Version (technology)
In technology, a socket is understood to be a device that allows replaceable components to be quickly attached and detached.
When the component is plugged in or screwed in, the connection of the power lines (e.g. electrical contacts or compressed air connections ) is usually established at the same time . Special connection work (clamping, soldering) is therefore not required.
The counterpart on the replaceable component is called the base , but colloquially it is often also the socket , the other side.
Types and examples
Lamp holders
Screw sockets
- Incandescent lamps , energy-saving lamps and gas discharge lamps with Edison screw bases (the most common are E10, E14, E27, E40, the number indicating the nominal diameter in millimeters)
Sockets with bayonet locking
- for incandescent lamps, glow lamps and LED indicator lamps with bayonet sockets in vehicles and systems (vibration-proof)
- for projection lamps (defined position of the filament), thyratrons
- on high-voltage halogen lamps (e.g. GU10) and fluorescent lamp starters (plug pins with head create the bayonet lock)
Jacks
- for plug-in bases of electron tubes , energy-saving lamps and incandescent lamps
- For plug-in relays , some can also be used for PCB relays ( circuit board connection pins )
- Sockets for individual transistors (previously and on test devices)
- Plug-in sockets for integrated circuits in DIL or SIL housing
- Zero force sockets (plug-in sockets without insertion force): "Sockets" for microprocessors with a large number of pins
Further versions
- "Base" for PLCC - circuits : contact at all four side edges
- coaxial sockets for high-frequency diodes (see for example tip diode ) and disc triodes
- Socket for the RV12P2000 electron tube (built from 1937): pins across the direction of insertion
- solderless versions or adapter for BGA - circuits
- Sockets or receptacles for accumulators , SIM cards (mobile phones), SIMM memory modules ( PC ), ink cartridges ( inkjet printer ), etc.
Sockets or sockets for ICs
The term socket is often used in connection with ICs , which is probably a wrong translation of the English socket .
IC sockets can initially be divided into the categories of production sockets and test or programming sockets . The first type are IC sockets that are used in end products, so their implementation must be reasonably priced for the application. The second category relates to IC sockets that are used specifically in development or production, for example to connect an IC to a programming device in order to program internal memory. This type of IC socket is usually designed for a high number of cycles and can easily reach prices in the three-digit euro range.
Since the arrangement of the operating voltage pins is standardized in many ICs (e.g. TTL series) (see pin assignment ), there are also sockets that have a back-up capacitor ( tantalum capacitor or electrolytic capacitor ) installed between these two diagonal pins, such as you would otherwise have to place it separately near most ICs on the circuit board anyway . This causes a significant reduction in the dynamic internal resistance of the power supply.
