According to the electrical contacts of the connector parts quantity can be divided into single core circuit connector and multi-core self-short circuit connector, single core circuit connector is a relatively simple structure, as long as the solution to a single contact between the enclosure and the problem of short circuit can be automatically, and multi-core self-short circuit connector are relatively more complex, not only to solve the contact between the enclosure and the automatic short circuit problem, is to solve the contact and the contact between the automatic short circuit problem.

According to circuit function lifting sequence can make the following classification : one is when the connector is inserted and combined, first lift short circuit function, and then realize the contact normal insertion; another is when the connector is inserted and combined, first of all to achieve contact insertion, lifting the short-circuit function; another is the sequence does not make requirements.

In accordance with the contacts of connector combination is different, can be divided into high and low frequency mixer type circuit connector, photoelectric mixed type circuit connector, comprising a fluid channel circuit connector, and hybrid electric ( low frequency, high frequency ), light, fluid ( gas, liquid ) in one of the circuit connector, the connector from the nature are in the circuit connector is added on the basis of other channel.

According to circuit function in the plug or the socket can be divided into circuit from short circuit plug connector and socket connector, the circuit structure have no essential difference, is only in the shell structure design is somewhat different.

In the circuit connector structure for a certain extension, such as on the connector design corresponding to the floating structure, coupled with the appropriate guide mechanism, can become with automatic alignment function circuit connector, can be installed on a fixed rail, meet the requirements of mechanical plugging.

Main performance index

Circuit connector is different from general electric connector is the main difference between self short circuit, short circuit resistance is its special performance requirements, the general requirement is a short circuit between the contact resistance15mW, life test is less than or equal to 30mW.
