How to change a chandelier cartridge: step by step instructions. How to choose lampholders for chandeliers How to unwind an e14 pendant lampholder

One of the main components of a chandelier or lamp is an electric cartridge, through which not only fixing the light bulb and transferring current to it, but also fastening the ceiling and other elements to control the light source is carried out.

The design of the product consists of the following elements:

• body of cylindrical configuration;
• internal threaded sleeve;
• ceramic insert;
• a pair of brass or copper contacts;
• bottom;
• fasteners.

The design of the body of the product eliminates the possibility of electric shock when screwing in the light bulb. This is due to the fact that when the central contacts come into contact, the base is inside the cartridge.

Types of cartridges

Structurally, there are several types of them according to the method of fastening light bulbs:

1. Screw threaded(Incandescent bulb twists inward). Suitable for standard incandescent lamps.
2. Pin(fastening is carried out by means of fastening tabs or pins located on the outer surface of the product). Used for fluorescent, halogen and.

The material used to make the case is:

The principle of operation of all cartridges is identical, the differences are only in size and design. All products are designed for operation in the mains 220V.

There are the following types of them (the value “E” with a number is used for designation, where the number corresponds to the diameter of the sleeve):

1. E5 and E10. They are rarely used due to the consumption of a considerable amount of current with little light output.
2. E14. Product small size, is used with decorative lamps, the so-called "minions", of identical diameter. Their power does not exceed 60 watts.
3. E27. The most commonly used threaded socket designed for use with conventional, fluorescent, LED and halogen lamps.
4. E40. This type is designed for street lighting, where powerful lamps of large sizes are used.

Cartridge selection

When choosing this product, first of all, you should give preference to a well-known and proven brand.

To avoid difficulties with fastening, the design of the new cartridge must match the type of product previously used in the chandelier. It is better to give the advantage to a ceramic product due to its reliability during operation.

Basic selection requirements:

• the power of the lamp to be connected;
• diameter corresponding to the type of cartridge;
• marking;
• parameters: dimensions, power;
• the price should not be too low.

The cost depends on many factors, in particular on the type of product and its manufacturer. Today the market provides the consumer with a wide choice of both Russian and imported brands.

The price range is quite large:

1. Type E27:
   • domestic production - 25 rubles;
   • China - 45 rubles;
   • Italy - 130 rubles.
2. Type E14:
   • domestic production - 20 rubles;
   • China - 20 rubles;
   • Italy - 90 rubles.
3. For halogen lamps:
   • domestic production - 15 rubles;
   • China - 30 rubles;
   • Italy - 150 rubles.

How to change the cartridge in the chandelier

Replacing the product is not difficult and does not require experience in the field of electrics, however, it requires caution and compliance with all rules and recommendations.

Reasons for replacement

First of all, the need to change the product is indicated by the fact that the lamp does not glow when the switch is activated. This is due to rusting of the sleeve or center contact. As a rule, cleaning does not give a positive effect.

Replacement is required if:

1. The presence of cracks and other defects on the outer part of the body;
2. When the internal elements come into contact, a short circuit occurs.
3. Exit from working state.
4. The service life is 5 years.

Necessary materials and tools

In the process of work you will need:

• replacement item;
• terminal blocks for connecting electrical wires;
• indicator mini-tester (screwdriver);
• insulating tape;
• construction knife with replaceable blades.

Step by step replacement guide

Replacing the cartridge in the ceiling lamp is performed in the following sequence:

They place the chandelier on a table or other convenient plane, disassemble it by removing all the shades and unscrewing the light bulbs so as not to break

Checking work

After fixing the chandelier to the ceiling, a lamp is screwed into the cartridge and an electric current is supplied. If the replacement work is done correctly and all contacts are connected, the lamp will glow.

If, after replacing the product, any problems are found (flashing of the lamp or its burnout), their causes should be found. Alternatively, it may be an incorrect connection of the current-carrying wires.

1. Perform replacement without de-energizing the room, is strictly prohibited, often this leads to tragic consequences.
2. If problems are found in the main it is necessary to make a complete or partial replacement of it.
3. Sometimes cartridges initially have branch wires, so when connecting different kind wires, for example, aluminum acts as the main one, and copper comes from the lighting fixture, it is advisable to use special terminal blocks for connection. If there are none, the wires should be connected, twisted and covered with insulating tape.
4. Before removing the chandelier, you should remember or sketch the wiring diagram to prevent misconnection.
5. If the reason for withdrawal ceiling lamp is a cartridge that has gone out of tune, you can try to repair it. Often, brass plates move away, oxidize or rust. In this case, they can be cleaned with a sandpaper. You should also inspect the contact fasteners under the ceramic insert. If necessary, they are cleaned and twisted. After a thorough inspection, the cartridge is assembled and the lamp is screwed into it, the ends of the lamp wires are placed in the carrier. The result of a properly carried out repair will be the emission of light by the lamp.
6. Sometimes it is not possible to remove the incandescent lamp from the cartridge - the base is jammed, and when the lamp is unscrewed, only the glass bulb is removed. So that in the future the cartridge can be used in other chandeliers, it is necessary to unscrew the cylindrical element of the product body, holding it by the lower part. If these manipulations do not positive result, the base can be unscrewed with pliers, taking its edge and turning it in the cartridge.

Any adult person at least once in his life faced with the simplest, at first glance, situation - the incandescent lamp burned out and it needs to be replaced. It may seem that no problems can arise here. Unscrew the burnt one from the chandelier, in its place a new one - and that's it. But even here troubles can await.

Due to high humidity (oxidation and rust on the base and inside the socket), due to factory defects in the lamp or jump voltage, a situation may arise in which the base remains inside. It makes sense to figure out how to get the rest of the light element, that is, how to unscrew the bulb base from the cartridge. Someone might say, "Take off the lamp and work quietly." But there are much easier options.

Options for the development of events

During a power surge or a factory defect, an incandescent bulb (or halogen) burst during operation. Then in the cartridge, in addition to the base itself, there will also be sharp fragments from the light bulb sticking out of it. In this case, you need to be especially careful when dismantling the remaining part of the light fixture. Or it may happen that the flask broke when unscrewing, if there is rust inside the cartridge, which prevents the base from being turned out.

Also, the cause of such a nuisance can be such a marriage, in which the bulb itself is easily separated from the metal base.

How to unscrew a broken light bulb in any of the above cases without resorting to the help of specialists? The main thing is calmness. You should not rush anywhere, pulling out the remains of a damaged light element, so that some other trouble does not happen, such as a cut on glass or a broken cartridge.

Solutions

There are several ways to unscrew a light bulb if it has burst, and each of them is good in its own way. The main thing that needs to be done first is to de-energize the damaged chandelier or other lighting device.

Ideally, of course, if the wiring was carried out with several inputs, then it is possible to turn off the power from the circuit breaker of only part of the room, leaving you the opportunity to connect a portable lamp in the next room. If this is not possible, then you will have to de-energize the entire apartment and highlight when removing the broken light bulb with a flashlight or cell phone. If, in addition to the base, the central tube remains in the cartridge, then it breaks neatly.

When the power is turned off, you should not rely on the switch of a broken lighting device - it can be powered incorrectly during installation, and interrupt not the phase, but the neutral wire.

Pliers

Carefully removing the remnants of the fragments, you need to pick up the edge of the base with pliers (without grabbing the cartridge) and start rotating it counterclockwise. If the metal base is stuck or stuck due to rust, it does not hurt to first sprinkle the stuck surface with cologne or toilet water so that the liquid gets between the base and the cartridge, and give a little time to soak. Also acceptable is the option in which the pliers are stuck inward and unclenched, after which you can try to turn the part out.

Disassembly

This option is not feasible with new-style ceramics. It can be used if the cartridge is made of carbolite, because it will be collapsible. How to unscrew the cartridge? It is not difficult. It is necessary to carefully, holding the base with one hand, unscrew the cylinder, dividing it in two. A “skirt” with a plinth stuck in it will remain in the hands. Here, no longer under the ceiling, you can safely unscrew the base of the light bulb in any of the proposed ways.

Plastic bottle

This option requires caution, because hot plastic that gets on the skin is a very painful thing. So, the neck of a soda bottle is heated over an open fire to a melting point, after which it is inserted inside a metal base. You need to wait a bit until the plastic cools down, after which you can turn the bulb out of the cartridge. The fact is that the heated plastic sticks inside the base of the light bulb, penetrating into the bumps, with the help of which it fixes the base. At the same time, part of the oxidation and rust burns out from the heating of the base.

Champagne cork

Similarly, you can use a cork from wine or champagne. Its edges need to be slightly sharpened by chamfering, and then driven inside the stuck base of the light bulb. Slowly, with a gentle twisting motion, try to unscrew the base and pull it out. Any metal base of any lamp with a screw base is unscrewed exclusively counterclockwise - this must be remembered so as not to waste time and effort.

Potato

Probably the most interesting and unusual way of all presented. They can be used if fragments of the flask stick out of the base. The potato must be cut into two parts, take one of them in your hand and, as it were, “plant” the cut part on the protruding pieces of glass. After that, simply unscrew the base from the cartridge.

Measures to prevent such troubles

The first thing to note is that you should not put lamps that exceed the limit of the possible power of the cartridge or lamp so that they do not burst. The fact is that the more current the light device consumes and the brighter it shines, the more heat is released during its operation. And this can lead to the situation described above.

Of course, the lamp must be tightly screwed into the socket, but nevertheless, during installation, it is necessary to find such a tightening point so that it can then be unscrewed. There is no point in pulling the lamp all the way, as far as there is enough strength. You can also pre-lubricate the base thread with graphite.

It is not necessary to leave greasy stains on the glass, it is advisable to work with gloves. In addition, the hands will be more protected with the option of splitting the lamp.

You should buy lamps only in trusted stores and not chase cheap goods, which are most often illiquid, that is, they should not have been on sale at all.

By following simple rules, you can be sure that even if such a nuisance happens, it is easy to get rid of it.

An electric bulb holder is a device that is a connecting node between a lamp and an incandescent element. In addition, with the help of additional fasteners, a lampshade or shades are hung. Through such a part, current is transmitted through wires. The screwed burnt element is easily changed due to the simplicity of the product body.

Product marking

Depending on the diameter of the threaded part of the assembly, the products have several varieties:

Connecting an electric chuck

To understand how to connect a light bulb socket, you need to have a good understanding of its device. The central contact is made of brass. It is pressed against the ceramic insert. For this with reverse side There is a threaded steel plate. A screw is wrapped in it, which passes through ceramics and brass.

The screw is screwed in with good force, because an electric current passes through the part to the contact. A side brass plate is placed next to it, which is attached according to the same principle.

When connecting wires, rings for fasteners are formed on them. They pass through its central hole in the body and are fixed on steel plates. The phase from the network is fed to the central contact.

After that, a threaded sleeve for a light bulb is screwed on top. Then the selection of the lamp is carried out.

Product fastening

Typically, the fastening of the cartridge in chandeliers or lamps is carried out at the bottom of the case. It is unacceptable to put a weight load on the wires. For fixing in the chandelier from below there is a hole into which a plastic sleeve is inserted. The wiring runs into it and is fixed with a bolt. A more reliable mount is a metal tube. Wires run through it. The nuts located on it allow the installation of ceiling lamps and chandelier caps.

There are special cartridges for installing ceiling lamps or wall lamps. They are carved on the outside. The clamping of hinged elements is carried out with the help of plastic bushings, which are screwed onto the threaded part of the cartridge.

It should be remembered that it is impossible to install a high-intensity light bulb, because the plastic washers begin to melt.

Reasons for replacing the design

Over time, the product needs to be replaced. The need arises for the following reasons:

Before replacing the cartridge, there are some tips to consider:

Dismantling and installation works

Armed with the necessary tools, you can take on the dismantling of the old structure and the installation of a new product. . The step by step instructions are as follows:

Power is supplied to the network, and the device turns on. If the work is done correctly, then the light should light up.

An electric cartridge is a product that is present in any lamp. Over time, the structure fails. The cause may be the presence of rust or a crack in the case. Main, notice it in time and work to replace it.

If one of the bulbs in the ceiling lamp stops burning, and after replacing the lamp, the light does not appear, one of the reasons for the breakdown may be the failure of the cartridge. Most often, contacts in this element burn out or the case itself breaks, which cannot be repaired. Next, we will tell you how to change the cartridge in the chandelier with your own hands, providing instructions in pictures and visual video tutorials.

So, in order to correctly replace the failed element, you must perform the following steps:

1. Turn off the light on the dashboard. It is strictly forbidden to carry out replacement under voltage!
2. . You can, of course, change the cartridge without removing the lamp, but this will be much more difficult. All that needs to be done is to disconnect the connection of the conductors (usually twisted or, as in the photo) and remove the chandelier from the hook or plank.
   
3. Disassemble the lighting fixture by removing the glass shades and unscrewing all the bulbs (usually e27 or e14 - minion) so that they do not break during the repair process.
   
4. Unscrew the visible part of the electrical cartridge and disconnect the wires. In some models, the contacts are on the base. In this case, you will need to unscrew the clamping screws.

   
   
   

5. Dismantle the ceramic base of the product.
6. Replace the lamp holder by connecting the phase to the central contact of the base, and zero to the remaining free one. You can identify the wires by color by reading.
   
7. Reassemble the chandelier in reverse order.

If you have a lighting fixture with halogen lamps, we recommend that you view this lesson:

How to change cartridge?

That's all I wanted to tell you about how to change the cartridge in the chandelier with your own hands. We hope that the provided replacement technology with photo and video examples was useful and interesting for you! By the way, this method can be suitable not only for a ceiling lamp, but also for a table lamp if it is broken.

Currently, lighting devices use various light sources that are connected to the network through cartridges. The cartridges themselves are an important link in wiring diagram devices. And some malfunctions of these elements require their replacement. But to do the job yourself, you need some basic knowledge.

Chandelier holder: types

Since the advent of incandescent lamps, devices have also been developed by which the lamp is connected to the mains - cartridges. From Soviet times to the present day, only two types of cartridges are used in chandeliers.

Connector types:

In the manufacture of cartridges, two types of materials are mainly used - plastic and ceramics. Ceramic products are more brittle than plastic, but they are very resistant to overheating. Thus, they allow the use of incandescent lamps of any power.

Cartridges made of old-style plastic were also distinguished by increased resistance to overheating and mechanical stress. But modern products, when working with lamps of higher power and temperature, quickly fail.

Note! Currently, with these types of socles, not only incandescent lamps are produced, but also halogen and LED light sources.

One of the design elements of plastic cartridges is the so-called "skirt", which allows you to mount products on various surfaces or structures (for example, in a table lamp with a shade).

These devices are divided into two types and according to such a parameter as the method of fastening the conductors in the terminal. It can be with screw or screwless contact.

Replacing a cartridge in a chandelier: dismantling the device

Replace the cartridge in the chandelier, enough simple work. But to do it right, you need to know in what order it is produced. And be sure to follow the safety rules.

Operating procedure:

• Power outage;
• Dismantling the chandelier;
• Removing the cartridge.

Before starting dismantling, it is necessary to turn off the power supply to this conductor. To do this, in the switchboard, you need to turn off the circuit breaker. Lighting groups are equipped with automatic machines for 10 or 15 Amperes.

Note! After turning off the mains voltage, using an indicator screwdriver, be sure to check for its absence. When touching the wires, there should be no indication on the device.

Since in a chandelier, each cartridge is connected by wires, it is first necessary to determine which type of clamp is used. If screw, then using a screwdriver, the screws are released and the wires are pulled out. If the clamp is screwless, then to remove the wires, it is better to use a thin knitting needle, which presses the spring holding the wire, making it easy to pull it out.

How to properly connect the cartridge to the wires

How well the connection is made will depend on how long and correctly the device will work. It is worth noting that the connection of wires to cartridges depends on several important parameters.

Connection Features:

• Characteristics of the conductor;
• Terminal type.

These works are carried out both when the cartridge is connected to an already laid wire on the ceiling, and when installed in a lighting fixture.

An important parameter when connecting a wire is the type of core used in it. For example, an electric chuck with screw terminals can be easily connected with both stranded and solid wires.

Note! The best option wires for connecting cartridges, is a single-core conductor.

But if it is easy to connect wires with any characteristics to a screw terminal, then connecting a stranded cable to a self-clamping terminal is a little more difficult. To do this, you should use the following tricks.

First of all, it is necessary to disassemble the cartridge and remove the insulation from the wires. The insulation is removed to a length corresponding to the length of the terminal.

Most The best way is the use of a soldering iron. In this case, the strands of a stranded conductor are treated with flux and tinned. Thus, it is possible to achieve a certain rigidity of the conductor.

Provided that the soldering iron is missing. Any hard metal product can be used. It can be a needle or a nail. A prerequisite is that the section of the object is greater than the section of the wire.

How to fix a light bulb holder

Many malfunctions associated with lighting devices can be easily fixed on your own. To do this, you will need certain knowledge and tools for electrical work.

Faults:

• One of the wires burned out;
• The light bulb burst;
• The base of the lamp does not reach the contacts of the cartridge.

Quite often, due to incorrect connection, one of the wires of the power cable burns out. In this case, you should not clean the burned-out contact and try to connect it. To do this, you need to disassemble the device, disconnect the second wire, and use pliers or wire cutters to make them the same length. After that, the wires are stripped and connected to the cartridge.

Note! When working with electricity, follow the safety regulations.

It happens that an incandescent lamp screwed into the cartridge explodes or the bulb of the lamp is separated from the base. At the same time, the base itself remains in the cartridge. Removing this is very easy. The switch of this line is switched to the “off” position and the base is unscrewed from the cartridge with pliers.

One of the most common malfunctions is the lack of contact between the light bulb and the contacts of the cartridge. In this case, using a screwdriver, the cartridge contacts are bent to their original position.

If there is no contact after that, then it is necessary to clean the terminals of the cartridge from oxide. If necessary and design features cartridge, contacts can be changed and new ones installed.
