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 the equipment, trying to simplify their maintenance as much as possible. Cartridge G9 refers to products of this type.
Cartridge
Two types of cartridges are most widely represented on the market: for threaded (marking - E) and pin (indicated by G) connections. The threaded version is familiar to most home lights. 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 in the design of the room, but also in 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 casing;
- contacts;
- sleeve;
- fasteners.
The cartridge G9 is equipped with a sleeve with a spring socket. The bulb instead of a thread on the base has several pins and does not screw in, but simply sticks into the base. They reliably "sit" in the nests, providing excellent contact. Socket Specifications:
- the distance between the holes (grooves) - 9 mm;
- the outer diameter of the product is 17.78 mm;
- height - 22.86 mm.
The cartridge for G9 halogen lamps was developed and found wide application. As a rule, they are used for decorative or directional lighting:
- window dressing, paintings and other works of art;
- in a variety of spotlights, including in suspended ceilings;
- for decorating furniture designs;
- for highlighting aquariums and heating terrariums.
Modifications
In the marking, the letter G indicates that the lampholder is used to install lamps with a pin base. The number "9" defines the distance between the pins, which is equal to 9 mm. Cartridge G9 is available in various versions and may vary:
- with two screws;
- with threaded connection (mounted on the back of the cartridge);
- complete with a ring and thread (with their help, a plafond is installed on the cartridge).
- by type of connection with wires:
- wires are pre-connected to the cartridge;
- the presence of flat spring terminals.
All models are convenient and easy to operate. "G 9" is the second most popular after products marked "E".
Material
For the manufacture of such products, either ceramic or heat-resistant plastic is used:
- Cartridge G9 ceramic is one of the most reliable and safe products. Ceramics 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 safe operation of electrical appliances. The plastic cartridge G9 is lightweight, does not fight in the event of an accidental fall, perfectly withstands temperature fluctuations, cheaper than ceramic counterparts.
Both options are in equal demand among consumers. Ceramic products are preferred if the lighting device is turned on for a sufficiently long time. Plastic is quite suitable for furniture or decorative lighting. Light weight and ease of installation will create any combination of directional lighting.
Features
The holder for the G9 lamp has a number of features:
- tightness: dust, moisture do not get on contacts, condensation does not form;
- the ability to use special adapters (usually ceramic) make them universal;
- ease of operation (a teenager will be able to insert pins into grooves);
- produced under energy-saving (fluorescent), LED, halogen lamps ;
- grooves reliably hold pins of a lamp, providing reliable contact;
- powerful spring mechanism and light bulb;
- material reliability: high-quality ceramics are used for the case, heat-resistant braid for wires;
- disposability: cartridges for halogen bulbs cannot be repaired, in case of damage they are simply replaced with new ones.
Modern electronic equipment and advanced technologies make it possible to achieve perfect alignment of the grooves and pins, which significantly increases their reliability.
