Detailed Description

Embodiments of the plug and receptacle assembly of the present invention are further described with reference to fig. 1-9.

The first embodiment is as follows:

the utility model provides a plug and socket subassembly, includes plug body 1, socket body 2, the last extension bar 3 that is equipped with of socket body 2, the last barb form arch 31 that is equipped with of extension bar 3, the last through-hole that 3 wear to establish of extension bar that is equipped with of plug body 1, the last locking device who cooperates with 3 of extension bar that is equipped with of plug body 1, length is greater than plug body 1's thickness when extension bar 3 stretches out the state, through extension bar 3 and locking device, can fix plug body 1 who inserts in socket body 2 on socket body 2.

Locking device includes card 4, be equipped with first through groove 41 on the card 4, card 4 constitutes joint portion 411 with protruding 31 butt department on the extension bar 3, be equipped with card groove 11 on the plug body 1, card 4 slides with card groove 11 and is connected, be equipped with V type groove in the card groove 11, V type groove cooperatees with the V type arch on the card, prevent card 4 slip in-process roll-off card groove 11, be equipped with lug 12 in the card groove 11, be equipped with the second elastic component between opposite side and the lug 12 for joint portion 411 in the first through groove 41. The second elastic element is a second spring 7, the second spring 7 is in a tensioning state in a normal state, and the clamping portion 411 on the clamping piece 4 is clamped into a groove formed by adjacent bosses on the extension rod 3.
