The middle part of described shell fragment outer surface and the terminal projection that convexes with claw respectively and turn up, described catching groove setting or be formed at claw and projection between.
Described plug positive stop has the part extension to be suspended at the shell fragment top.
The technical scheme of shell fragment locking type electric connector socket of the present utility model is: a kind of shell fragment locking type electric connector socket, the side of the Socket casing of described socket is provided with the breach that cooperates with plug, on breach, be hung with on the side of Socket casing can hold shell fragment by and with shell fragment on catching groove in the mutual buckle that cooperates of button, the side of Socket casing is provided with the socket positive stop that cooperates with plug.
Described socket positive stop is arranged at the breach both sides, and described buckle two ends are connected between the two socket positive stops and stride and be located on the breach.
Be respectively equipped with shell fragment and breach on the plug of the utility model electric connector and the socket, when plug and socket plugged together, the shell fragment of position correspondence plugged together and makes catching groove on the shell fragment and the buckle on the breach to detain mutually to cooperate mutually and realizes locking with breach; It is inner and shell fragment is protected that shell fragment is taken in breach and buckle, also be provided with in addition corresponding plug, socket guide vane end stop can be when plug plugs together with socket roof pressure cooperate realization to plug together spacing on the direction, reduce overvoltage or impact to shell fragment or connector.
In addition, the catching groove setting on the described shell fragment or be formed at claw and projection between, but claw block buckle is realized anticreep, projection is beneficial to and pushes shrapnel.
In addition, the plug positive stop has part to extend to be suspended at the shell fragment top, but the block shell fragment limiting its amplitude of turning up, thereby prevent that shell fragment from fractureing because of excessively turning up.
In addition, the inside and outside surface and the plug casing junction of shell fragment root are all excessive with circular arc, and the root shape of shell fragment is enlarged gradually by export-oriented junction, and above structure can increase the intensity of shell fragment.
In addition, buckle and socket positive stop connect as one, and make the buckle two ends be connected between the two socket positive stops and stride and be located on the breach, improve the intensity of buckle.
