Shell front is also arranged with lock ring, and the inner wall of lock ring is adapted with the outer wall of the jack housing, when plug and socket tight to mortise lock,
The snap lock collar, which is located at the rear portion of locking positioning key and is stapled, to be covered.It efficiently solves pushing away for the prior art
The problem that tensile capacity existing for pull-type electric connector is poor, reliability is low and structure is complicated, difficulty of processing is big.
It but is by lock ring to snap lock collar when this connector is locked there is also following problems, plug and socket
It carries out radial limit, snap lock collar is limited on plug extraction direction by locking positioning key, and plug is plugging together
Direction on limit then by being limited at the end of plug and step inside socket, in processing, it is difficult to ensure that working as
The end of the end face and plug at step when snap lock collar and locking positioning key are in the position of block limit inside socket
Just contact, if the end of plug is too close at a distance from the step surface inside socket, when plugging together, snap lock collar also not into
In the space for entering locking positioning key rear portion, the front end face of plug has been withstood on the step surface inside socket so that plug and insert
Seat can not lock;If the front end face of plug and step surface inside socket are apart from too far, when snap lock collar comes into lock
When in the space at tight positioning key rear portion, step surface of the inserted terminal identity distance of plug inside socket can then be led with a certain distance from still having
Cause plug in socket along axial shaking, cause to connect it is unstable, on electric connector safety stablize using influence it is very big.Therefore,
In order to guarantee the normal engagement of plug and socket and guarantee not shake each other upon engagement, then need to have plug and socket higher
Requirement on machining accuracy.
