Description
Technical field
The present invention relates to a kind of pin connector and push-pull connector components.
Background technique
The locking device of the round electric connector of the prior art mostly uses greatly screw thread or buckle, ball lock form, screw thread
Structure is to achieve the purpose that locking-type plug connector and socket using the threaded engagement of the two；Buckle structure is screwed in by bail
Card slot achievees the purpose that locking-type plug connector and socket.First two structure requires the lock sleeve on rotary connector connector,
Not only cause grafting or the breaking course of pin connector and socket cumbersome laborious, and rotation process is empty in some installations
Between limit to, fast-mating and isolated occasion use required to be very limited.Latter needs on circular housing circumference
Even processing steel ball hole, and steel ball is placed in and carries out turning over riveting in hole, it is very high to the required precision of hole machined, turn over riveting required precision
Height, especially to the product for having coating requirement, the subsequent corrosion resistance for turning over riveting and being also easily destroyed coating, therefore the life of product
Cost is produced with regard to relatively high.
In view of the above problems, the Chinese patent that Authorization Notice No. is 202159836 U of CN discloses, one kind is plug-type to be electrically connected
Connect device, including circular plug (i.e. pin connector) and socket (i.e. socket connector), the front end outer wall of the plug body
Several locking positioning keys are equipped with, the inner wall of jack housing is equipped with compatible keyway, sets on the front end outer wall of jack housing
There is an annular groove, the depth of annular groove is greater than the thickness of the keyway slot bottom, snap lock collar is equipped in annular groove, outside the plug
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.
Summary of the invention
