The electromechanical industry offers consumers a wide variety of products that are in demand both in industrial production and in everyday life. Engineers are constantly working to improve equipment, trying to simplify their maintenance as much as possible. The G9 cartridge belongs to this type of product.
Cartridge
There are two types of cartridges on the market: for threaded (marked - E) and pin (marked G) connection. The threaded version is familiar to most home fixtures. The pin version is gaining popularity due to its convenience and the ability to use unusual lighting points in the interior. Designers can offer dozens of options for using spotlights not only when decorating a room, but also furniture.
The main task of the cartridge is to ensure the transmission of electric current to the lighting device. The design consists of several elements:
- outer case;
- contacts;
- sleeve;
- fasteners.
The G9 chuck is equipped with a spring-loadednest. Instead of a thread on the base, the light bulb has several pins and is not screwed in, but simply stuck into the base. They securely "sit" in the sockets, providing excellent contact. Socket specifications:
- distance between holes (grooves) - 9 mm;
- outer diameter of the product - 17.78 mm;
- height - 22.86 mm.
Designed and widely used socket for G9 halogen lamps. Typically used for decorative or directional lighting:
- lighting showcases, paintings and other works of art;
- in a variety of spotlights, including suspended ceilings;
- for decorating furniture designs;
- for lighting aquariums and heating terrariums.
Modifications
In the marking, the letter G indicates that the socket is used to install lamps with a pin base. The number "9" determines the distance between the pins, which is 9 mm. The G9 cartridge is available in different versions and may vary:
by type of attachment:
- with two screws;
- with threaded connection (mounted on the back of the chuck);
- complete with a ring and a thread (with their help, a cover is installed on the cartridge).
by wire connection type:
- wires are pre-attached to the socket;
- the presence of flat spring terminals.
All models are convenient and easy to use. "G 9" ranks second in popularity after products withmarked "E".
Material
For the manufacture of such products, either ceramics or heat-resistant plastic are used:
- The G9 ceramic chuck is one of the most reliable and safe products. Ceramic is an excellent insulator that minimizes the possibility of short circuits.
- Plastic sample. The modern chemical industry can offer plastic with characteristics that meet all the necessary requirements for the safety of electrical appliances. G9 plastic chuck is lightweight, does not break when accidentally dropped, perfectly withstands temperature fluctuations, is cheaper than ceramic analogues.
Both options are in the same demand among consumers. Ceramic products are preferred if the lighting device is turned on for a sufficiently long time. Plastic ones are quite suitable for furniture or decorative lighting. Lightweight and easy to install, you can create any combination of directional lighting.
Features
G9 lampholder has a number of features:
- tightness: dust, moisture, condensation does not get on the contacts;
- the ability to use special adapters (usually ceramic) makes them universal;
- ease of operation (even a teenager can insert the pins into the grooves);
- produced for energy-saving (fluorescent), LED, halogen lamps;
- grooves securely hold the lamp pins, providing reliablecontact;
- strong spring mechanism and light bulb;
- Reliable materials: high quality ceramics used for body, heat resistant braid for wires;
- disposable: halogen bulb sockets cannot be repaired, if damaged they are simply replaced with new ones.
Modern electronic equipment and cutting-edge technology achieve perfect groove and pin alignment, greatly improving their reliability.
