Do you know anything about electrical connectors?

2023-02-08
Electrical connectors of various types can be used in almost all electronic devices, and electrical connectors may play a key role in ensuring device performance. However, unreliable connectors can be the cause of faulty products or damaged electrical shortages. Because connectors are responsible for protecting the wires and connecting them to each other, many connectors are waterproof and weatherproof, so they work even in high-performance applications.
In theory, the connector should be resistant to many external factors, such as oil, pressure and water. In addition, it should be relatively easy to disconnect, while creating secure and tight connections when connected to other connectors. Desirable connector characteristics include low contact resistance, durability, high insulation, cost effectiveness, and reliability. The properties depend on the application, but generally your connector should have at least some of the features listed above.
The basic electrical connector has several different components, including: connector housing, pins and receptacles, receptacle retainers, seals, etc.
1. Connector cover 
The housing of the connector serves as the first line of defense against environmental hazards by protecting the internal connector assembly and preventing the external environment from contacting the ends of the uncovered wires. The housing itself has holes and openings to accommodate wires and pins. In addition, the inside of the housing is designed to hold everything in place by locking the pins and holding the seals together. 
2. Pins and sockets 
Pins and sockets are connected to each other and conduct electricity through connectors. The fit must be snug enough to ensure a strong connection, but loose enough so that disconnecting them is not too difficult. The number of pins and sockets will vary depending on the type of connector. 
3. Socket retainer 
The main function of socket retainer is to prevent pins and sockets from loosening. To do this, the plastic socket retainer presses upward against the plastic latch that holds the pin and socket in place, serving as an auxiliary locking mechanism, and the socket retainer is connected from the front end to the connector. 
4. Seals 

To prevent water from entering the connector, a rubber sealing ring is placed at each end. The wire enters the connector through a seal, effectively using pressure to block water.
