According to its functional purpose, the cartridge for bulbs is a special element by which the light source is fixed inside the device connected to the network. Any repair work associated with the installation of electrical equipment requires the mandatory performance calculations of wiring performance in the room. These events are often directly related to the wishes of the owner regarding the design, design projects are also taken into account. So, to create an original home in its design, it may be necessary to install various types of lighting devices, which will inevitably entail the need to install various cartridges. Therefore, you should figure out how to connect the bulb holder correctly, that is, in compliance with all safety rules.
What does the cartridge consist of?
In the process of working with electricity, it is very important not to forget about clearly regulated rules that can not only ensure normal operation of the equipment, but also maintain the health of homeowners.
Therefore, before thinking about how to install a bulb holder, you must firmly remember a few prerequisites:
- firstly, the element itself and the lamp mounted in it must correspond to each other. This means that the base of the light must be suitable;
- secondly, do not forget about the periodic replacement of electrical equipment, which explains the need to connect the lamp directly in the cartridge, and not directly from the network.
The principle of the device of this element is as follows: by means of a special screw, one of the wires is attached to the side contact, and the other is connected to the central one using the same screw.
The main components of this part are the sleeve, the housing and the central contact. All of them are fixed on the insulator.
Types of lampholders for lighting
It is no secret that the cartridge for bulbs can have any configuration, as a result of which there is a division of this element into 4 large categories.
- Threaded chuck having a diameter of 27 mm. Most often used in standard apartments and private houses, since such a sample is equipped with the most common base and is suitable for a standard light source.
- 14 mm threaded chuck. This type is used in devices equipped with small incandescent lamps. Such lighting is usually zonal, that is, not general, since the range of such equipment is not large.
- Cartridge with a diameter equal to 40 mm. The main lamps for such samples are large-sized models with high power (500 W and more). The scope of such equipment is outdoor lighting (streets, roads).
- A special type, called bayonet type, is resistant to even the most powerful vibrations. Such elements are very often used for transport, in addition, they differ from other threaded samples in that they are not screwed in according to the standard principle, but are inserted, since due to heavy loads and vibration, the standard cartridge can easily fall out.
Technical features of various tube cartridges
It is important to note that the bulb holder can be different not only in type, but also in accordance with the design features. Therefore, according to this parameter, several varieties can be distinguished, such as suspended (used for rooms with a high level of humidity), equipped with a special mounting mechanism, straight, inclined and others.
Ammo bodies also differ. So, the most popular are samples made of plastic or porcelain (more resistant to high temperatures).
Next, you should consider in more detail how to disassemble the bulb holder as correctly as possible and, just as importantly, safely.
Dismantling the lamp holder
In order to accurately divide the equipment into its components, it is necessary, firstly, to unscrew the upper fragment of the device so that its base is made of ceramic, which, in turn, is connected to the contacts. Then this part needs to be taken out and disconnected from all elements adjacent to it.
It is very important to understand how the bulb holder interacts directly with the wire. Connection of equipment to a stationary switch must be accompanied by a connection of a phase cable with a central contact. After that, it is important to make sure that the resulting system works reliably. To do this, you need to attach the light source with a socle to understand that the contact obtained as a result of assembly is bent to a distance of at least 2 mm. The assembly of the entire element is completed by wrapping the body in the form of a cylinder.
Further it is necessary to dwell in more detail on how to properly replace a decommissioned device.
Cartridge replacement
It is imperative to remember that the installation of a bulb holder must take place with strict observance of safety precautions.
First of all, you need to de-energize the shield, that is, turn off those machines in it that are directly responsible for lighting. After this, it is absolutely necessary to remove the lighting device in which the light bulb with the defective cartridge is installed. This should always be done to avoid the potential risk of harm to health.
After removing the lamp, you can proceed to disassemble the cartridge, the process of which was described above.
As a rule, the fastening of this element of the bulb falls on a tube of metal. This type of fixation is the most popular, since with its help it is possible not only to give the whole structure the greatest strength, but also to realize numerous design decisions due to the ability of such a mechanism to withstand the heavy load that falls on a metal tube. In addition, this part can be equipped with various nuts, which allows you to fix a variety of plafonds and decorative lampshades on the lamp.
If the wires inside are significantly outdated, they are also recommended to be replaced. It is not difficult to do this, just take out the old cables from the tube, and stretch new ones in their place.
The assembly of the cartridge ends in the reverse order. It is especially important to be careful, as any, even minimal damage to the insulation can cause short circuits.
Possible repair of the bulb holder
Thinking about how to make a cartridge for a light bulb with your own hands, the owners may encounter a number of problems associated with either installation difficulties or an elementary lack of experience in such work. Nevertheless, there are situations when it is imperative to dismantle or repair installed equipment. For example, a light source starts to work with less power, a specific sound (buzzing) appears, and sometimes a burning smell.
If any of these problems occur, you need to unscrew the device and carefully examine its cartridge. If his contacts have turned black, then it will be enough just to clean them.
It also happens that when the bulb is twisted out of the lamp, the bulb can peel off from the base. To fix this problem, it will be most correct to completely unscrew the base, while removing the cartridge case. This can be done both manually and using, for example, pliers.
One way or another, but a quality repair requires a complete disassembly of the cartridge and verification of all its connections. Subject to all the above rules, the lighting equipment will last a long time and will not disturb owners with frequent breakdowns.
