Type connector products division, although some confusion, but from a technical point of view, the connector product categories only two basic plans
Points: ① Press Overall structure: circular and rectangular (cross-section), ② according to operating frequency: low frequency and high frequency (3MHz for the sector to).
According to the above division, coaxial connectors belong circular, printed circuit connector belongs rectangular (printed circuit connector is indeed separated historically from a rectangular connector out of sui generis), and the popular rectangle connector trapezoidal cross section which approximates a rectangle. In 3MHz for the sector division and frequency division of the high-frequency and low-frequency radio wave it is basically the same.
As for the other by end-use, installation, special structure, special properties can also be divided into many different types, and often appear in publications and promotional materials manufacturers, but generally only to highlight certain characteristics and uses, the basic classification is still does not exceed the above principle of classification.
Taking into account the technological developments connector and the actual situation, its versatility and related technical standards, the connector can be divided into the following categories (sub-categories): ① low frequency circular connector; ② rectangular connectors; ③ printed circuit connectors; ④ RF connectors; ⑤ fiber optic connectors.
