Description
Technical field
The present invention relates to high-voltage electric connector field more particularly to a kind of secondary locking and delay unlocking structures.
Background technology
Electric connector is generally made of plug and socket, is realized being reliably connected for plug and socket by locking mechanism, is inserted
Head and socket, which plug together power connector in rear electric connector, to be contacted.High-voltage electric connector usually also contains high-voltage interlocking work(
Can, i.e., it will be after power connector completes physical connection, it is also necessary to its conducting be controlled by signal socket connector, then could allow high pressure
Circuit is initially powered up work；Similarly, when disconnecting high tension loop, signal socket connector should be made first to disconnect, by the electricity of high-tension line
Stream cut-out, then disconnects the connection of power connector again, the height that is connected to inside such a construction ensures electric connectors in separation
Operating personnel will not be damaged by pushing back road.
Most of existing high-tension connector uses snap lock structure, realizes plug by the flexible deformation of buckle and inserts
Seat is plugged together and is detached.But in actual mechanical process, the separating rate of plug and socket is possible to quickly so that signal patches
It does not pause in the separation process of part and power connector, almost simultaneously switches off.Electric elements are easy arcing at this time, influence to use
Service life, and there is also the risks of operator's accidental shock.
