SSQ-138-03-S-D

Rectangular Connectors - Headers, Receptacles, Female Sockets

The SSQ-138-03-S-D rectangular connectors are among the most popular and widely used connectors in the market, and they are often used to provide a secure and reliable connection between two electronic devices.

Application field

These connectors are widely used in a multitude of electrical and electronic applications including computers, routers, modems, switches, components of machines, cars, audio and medical equipment, electrical home appliances and instrumentation. They are also used in industrial control systems, communication systems, test and measuring instruments, lighting systems and automation control systems.

Working principle

The SSQ-138-03-S-D rectangular connectors are generally composed of one male plug and one female socket or one female plug and one male socket. The male plug generally has two rows of contacts that are inserted into the female socket. The female socket usually has one row of protruding contacts which are connected with the corresponding contacts on the male plug. The contacts on both sides form a secure connection when the male and female connectors snap together.

In order to ensure reliable electrical connection, SSQ-138-03-S-D connectors are usually equipped with latching mechanisms which snap into place when inserting the plug and socket together. At the same time, the contact pressure of the connectors is adjustable, and it also has a certain wear resistance and life cycle. The varied shapes and sizes of the connectors are designed to ensure that they can fit into different housings, covers and buss bars.

Because of their superior electrical and mechanical characteristics and their excellent adaptability, SSQ-138-03-S-D rectangular connectors have become an essential component of almost all electrical and electronic appliances, enabling them to perform at an optimal level.
