Connector overview and different forms of product classification

The connector is also called a connector, generally refers to an electrical connector, which is used in a car as a car connector. Automotive connectors are primarily used to connect two active devices to transmit current or signals.
The basic performance of connectors can be divided into three categories: mechanical, electrical and environmental. Another important mechanical property is the mechanical life of the connector.
Connector product category

There are only two basic ways to divide the connector product category:

1 according to the shape structure: round and rectangular (cross section);

2 according to the operating frequency: low frequency and high frequency (with 3MHz as the boundary).

According to the above division, the coaxial connector is circular, and the printed circuit connector is rectangular, and the currently popular rectangular connector has a trapezoidal cross section and is approximately rectangular. The frequency division of low frequency and high frequency and radio waves is also basically the same.

As for other uses, installation methods, special structures, special properties, etc., many different types can be divided, and often appear in the publications and manufacturers' promotional materials, but generally only to highlight a certain feature and use, the basic classification is still There is no more than the above division principle.

Taking into account the technical development and actual situation of the connector, from its versatility and related technical standards, the connector can be divided into the following categories:

1 low frequency circular connector;

2 rectangular connectors;

3 printed circuit connectors;

4 RF coaxial connector;

5 fiber optic connectors.
