A horizontally extending connecting block 231 is provided on the extension section 23 at the position corresponding to the supporting block 112.

[0039] The operating principle of the utility model is as follows:

[0040] like Figures 1 to 9 As shown, in this embodiment, the guide top ring 30 is made of nylon 66, and the locker 4 is formed by bending a spring steel wire. First, the sealing ring 3 is placed on the step surface of the step hole, and then the guide top ring 30 is placed. During the placement process, the lower end of the guide top ring 30 first moves along the first inclined surface 100 and shrinks. After shrinking into place, the outer wall of the guide top ring 30 abuts against the outer wall of the positioning block 10, and the guide top ring 30 continues to move, and the outer wall of the guide top ring 30 is separated from the outer wall of the positioning block 10. The guide top ring 30 expands and makes the limiting protrusion 31 move horizontally to the bottom of the positioning block 10, and the lower end surface of the positioning block 10 abuts against the upper end surface of the limiting protrusion 31 to limit the sealing ring 3.

[0041] Then, the fixing block 52 is adapted to be embedded in the connecting groove 511 so that the verification slider 5 and the verification piece 51 are clamped and fixed, and then the verification slider 5 and the verification piece 51 are placed in the placement groove 101. At the same time, the clamping block 501 is clamped and positioned with the clamping groove 103. In this way, the guide block 50 is connected and fixed with the strip groove 102, that is, the verification slider 5 and the verification piece 51 are fixedly placed in the placement groove 101.

[0042] Then, install the lock 4 on the shell 1. Specifically, open the two connecting rods 41 to the left and right sides respectively so that the positioning rod 43 can bypass the stop boss 113 and move to the position of the guide groove 114. Then release the two connecting rods 41, and the two connecting rods 41 move back horizontally and enter the clearance groove 11. The inner side wall of the positioning rod 43 fits with the bottom of the guide groove 114. At this time, the stop boss 113 can prevent the positioning rod 43 from moving outward; then push the lock 4 and make the limiting rod 44 move toward the positioning boss 22. In this process, since the positioning rod 43 fits and abuts against the groove wall of the guide groove 114, the middle parts of the two connecting rods 41 continue to retract and move back and move into the step hole until the positioning rod 43 abuts against the side wall of the extension section 111, and the inner side wall of the limiting rod 44 abuts against the outer side wall of the shell 1, thereby achieving the purpose of clamping and fastening with the shell 1 and standing by.

[0043] Then, if Fig. 9 As shown, the male plug 2 is inserted, the third inclined surface 24 abuts against the two connecting rods 41, and the male plug 2 continues to be inserted, and the outer wall of the male plug 2 simultaneously stretches the two connecting rods 41 to the left and right sides, and then the boss 20 simultaneously abuts against the upper end surfaces of the two guide blocks 50. Since the outer wall of the block 501 and the groove wall of the slot 103 are arranged with an inclined surface, under the action of external force and the condition that there is a gap between the two guide blocks 50, with the force of the male plug 2 being inserted and moved, the block 501 moves along the inclined surface of the groove wall of the slot 103, and the two guide blocks 50 are forced to move toward the middle, and finally the block 501 is separated from the slot 103, and the guide block 50 moves back under the influence of the deformation and giving way force, and the outer wall of the block 501 abuts against the groove wall of the strip through groove 102. At this time, with the continued insertion of the male plug 2, the boss 20 abuts against the guide block 50 and drives the verification slider 5 to move downward in the placement through groove 101.

[0044] Until the verification piece 51 is completely moved out of the placement slot 101, at the same time, the lower end surface of the positioning boss 22 is abutted against the bottom of the positioning slot 104 to limit the position, and the third inclined surface 24 is fitted with the second inclined surface 310, that is, the male plug 2 and the shell 1 are plugged into place. At this time, the non-embedded end of the verification piece 51 is rotated outward to pull out and the verification piece 51 is simultaneously moved out for collection.

[0045] At the same time, the limit groove 21 moves to the connection point between the clearance groove 11 and the step hole. The two stretched connecting rods 41 move back under the action of elastic force and move horizontally into the limit groove 21 through the clearance groove 11, thereby directly realizing the clamping and fixing between the male plug 2 and the shell 1.

[0046] When it is necessary to remove the male plug 2, an auxiliary tool is required to open the two connecting rods 41 to the left and right again, and at the same time, pull out the locker 4 horizontally until the positioning rod 43 moves to the position of the stop boss 113. At this time, the positioning rod 43 abuts against the bottom of the guide groove 11 and remains in an open state. The connecting rod 41 has moved out of the limit groove 21 and moved into the clearance groove 11, and the male plug 2 can be taken out; when it is necessary to remove the locker 4, the two connecting rods 41 are spread open and the stop boss 113 emerges, and the limiting rod 44 is pulled outward. Due to the provision of the clearance slope 115, the movement interference is reduced, and the positioning rod 43 can be quickly retracted and separated from the shell 1 at the position of the clearance slope 115.

[0047] It should be noted that the extension section 111 is provided to assist the movement of the horizontal limit lock 4, and the support plate 110 and the extension section 23 are provided to prevent the positioning rod 43 from tilting up or down, so as to prevent the connecting rod 41 from moving out of the limit groove 21 and affecting the connection state between the male plug 2 and the shell 1, while also avoiding installation interference; a through groove for limiting the upward and downward movement of the connecting rod 41 is formed between the connecting block 231 and the support block 112. Similarly, the support block 112 is provided to keep the lock 4 in a horizontal state in the moving direction, so as to avoid the influence of installation interference and cause the connection to be offset and not in place.

[0048] To sum up, in this embodiment, the insertion of the male plug 2 drives the verification slider 5 to push out the verification piece 51. After the verification piece 51 is removed, the locker 4 is pushed to make the male plug 2 and the housing 1 engage and fix, so as to determine whether the installation is in place; if the verification piece 51 cannot be disengaged from the embedded position, that is, when the verification piece 51 cannot be removed, the connecting rod 41 cannot move back into the limiting groove 21, and the male plug 2 is in a loose state, it indicates that the male plug 2 is not inserted in place, and the situation of inadequate installation can be discovered in time.
