Connector product type division Although some confusion, but technically, the connector product category only two basic division method: ① by the shape structure: round and rectangular (cross-section), ② by operating frequency: low frequency and high Frequency (bounded by 3MHz).
In the above division, the coaxial connectors are round and the printed circuit connectors are rectangular (historically, the printed circuit connectors are indeed separated from the rectangular connector) and the popular rectangles The connector has a trapezoidal cross section, approximately rectangular. To 3MHz for the boundaries of low frequency and high frequency and radio frequency division is basically the same.
As for the other uses, installation, special structure, special performance, etc. can also be divided into many different types, and often appear in the publications and manufacturers of promotional materials, but generally only to highlight a feature and use, the basic classification is still Did not exceed the above division principle.
Taking into account the technical development of the connector and the actual situation, from its versatility and related technical standards, the connector can be divided into the following categories (sub-categories): ① low-frequency circular connector; ② rectangular connector; ③ printed circuit Connector; ④ RF connector; ⑤ fiber optic connector.
