How to connect a bulb holder?

It is difficult to imagine a lamp without an electric cartridge. This part not only fixes the bulb and transmits current, but also serves as an integral component for other additional elements. These parts include: lampshade, ceiling and a variety of aesthetics. In order to understand how to connect a bulb holder, you need to get acquainted with all the nuances closer.

Cartridge

Before you install the cartridge for the bulb, you should pay attention to its device, state standards, types, connection methods and other interesting things.

Marking

If you believe GOST-R IEC 60238-99, then you can see that threaded cartridges are of three different types:

• E14 is a cartridge called a minion. Such a device is used in microwave ovens and refrigerators.
• E27 is used in the vast majority of fixtures.
• E40 is used for street lighting sources.

All of them have the same principle of action, and differences can be observed only in dimensions and design solutions.

Important! Any device has its own marking on the surface of the housing. It is needed in order to indicate the technical characteristics:

• The first of the list is installed only in those places where the current consumption does not exceed 2 A, at 440 watts.
• E27 - no more than 4 A, at 880 W.
• The latter - no more than 16 A, at 3.5 kW. All these devices operate at an alternating voltage of 250 V.

How to remove the cartridge from the chandelier? Let's not rush and get acquainted with the device of this useful device.

How is the cartridge arranged?

The device boasts three main elements: a body in the form of a cylinder, in which there is a threaded sleeve, a bottom and a ceramic insert. The thread is based on the principle of Edison. To transfer current, two brass contacts and two strips are used, with a thread applied to them for fastening.

Important! For safety reasons, it is necessary to apply the phase directly to the contact of the base, which is located in the center. Such measures will help minimize the chance of being affected by the human phase.

Triple cartridge

There are devices that can accommodate three lamps at once. Often, contacts may fall out of the device, so you should pay attention to working with such devices.

To the holes that are located in the contact plates, wires are attached. You can attach them with nuts and screws, but no one forbids using a soldering iron.

Important! It will be quite difficult for a person who has never done this before, so it’s best to rely on instructions that can be found on the manufacturer’s websites or on the box of the product itself.

We are already close to installing the bulb holder.

Installation of a conventional appliance

You must understand how the cartridge itself is assembled from the very beginning. Such knowledge will always be useful in case of repair:

• The brass plate is pressed firmly against the ceramic insert. The contact plate is fixed with a screw that is screwed into the steel plate. This screw is needed not only to fix the central contact, but in order to pass current through itself.
• The second brass plate is installed exactly the same way. The contact, which is located in the center, must be bent to the level of the contacts located on the side. Rings are formed directly on the conductors and are threaded through the bottom, attaching to steel plates.

When connecting a cartridge through a standard key, the phase must be connected to the contact located in the center.

Important! During assembly, all components must be checked for integrity. Take the lamp base and press firmly against the contact. If during contact, the deflection is measured in several millimeters, then you did everything right. In the opposite case, you should bend the contacts up.

Now screw the case itself to the bottom, use the finished device under any lamps.

Terminals

Progress does not stand still, so the home appliance market has long been boasting a new type of device, the wires of which are fixed using special terminals.

Terminals help significantly speed up the installation process for chandeliers and lighting fixtures. The case of such a device itself is made of plastic, and the contacts are held inside by rivets.

Important! Unfortunately, if the device breaks down, it will not work to carry out restoration work, which will force the consumer to seek a replacement.

Screwless cartridge

How to assemble a lamp holder if it does not have a thread? Everything is very simple. The housing is equipped with two pairs of holes in which the wires touch. Inside the cartridge, brass contacts are installed, which are some kind of spring. This whole structure serves to fix the wires.

Important! Paired openings allow you to connect cartridges in parallel in chandeliers and lamps, which have several bulbs. One device is powered by voltage, and the rest are simply connected to it.

In order to connect a contactless cartridge, you need to take the wire and get rid of the insulation on it exactly one centimeter, and then simply pass it into the desired hole.

But when working with such devices, there are nuances. It is no secret that the most used wires are stranded, and fixing them in contacts is quite problematic. Manufacturers solved this problem as follows: stranded wires are tinned in order to make them single-core.

Important! If you find it difficult to reach the wires with your fingers, you can resort to using tweezers.

How to repair a cartridge?

Did the lamp lamps begin to flicker or burn out? Most likely, the matter is in poor contacts inside the cartridge. The buzzing and smell of burning when turned on and off only indicates this.

To check this, unscrew the bulb and inspect the cartridge. Blackened contacts need to be cleaned. The cause of such blackening may be poor contact at the junction of the wires and the cartridge. In order to get rid of this problem, you must do the following:

1. Disassemble the electric cartridge.
2. Make sure that it is well connected to the current conductor.
3. Clean the contacts well if necessary.
4. If the flask moves away from the base, it is best to unscrew it by unscrewing the device from the bottom.
