The Product Category Of The Connector

Although the division of connector product types is somewhat confusing, from a technical point of view, there are only two basic division methods for connector product categories: (1) according to the shape structure: circular and rectangular (cross-section), (2) according to the operating frequency: low frequency and high frequency (bounded by 3MHz).

According to the above division, coaxial connectors belong to the circle, printed circuit connectors belong to rectangular (historically, printed circuit connectors are indeed separated from rectangular connectors from a class), and the current popular rectangular connector has a trapezoidal cross-section, similar to a rectangle. The division of low frequency and high frequency with 3MHz is basically the same as the frequency division of radio waves.

As for others, many different types can be divided according to use, installation method, special structure, special performance, etc., and often appear in publications and manufacturers' promotional materials, but generally only to highlight a certain feature and use, the basic classification still does not exceed the above division principle.

Considering 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 (categories:(1) low-frequency circular connector; (2) Rectangular connector; (3) Printed circuit connectors; (4) RF connector; (5) Optical fiber connector.
