The first placement groove 12 The second placement groove 13 is connected to the through groove 2. At the same time, rotating seats 19 fixed on the inner wall of the through groove 2 are provided on both sides of the double-headed locking bent rod 9. A horizontal axis 20 is fixed between the rotating seats 19. The outside of the horizontal axis 20 is rotatably connected to the double-headed locking bent rod 9. Torsion springs 21 are fixed at both ends of the double-headed locking bent rod 9. The torsion spring 21 is sleeved on the outside of the horizontal axis 20, and the other end of the torsion spring 21 is fixed on the inner wall of the rotating seat 19, so that the double-headed locking bent rod 9 can rotate along the horizontal axis 20, and a hook groove 8 is provided on the side of the limit block 5. The structure of the double-headed locking bent rod 9 is shown in the figure, and its end close to the limit block 5 can be clamped in the hook groove 8, so that the double-headed locking bent rod 9 can fix the limit block 5. At this time, the contact plate contacts the side of the shell of the plug connector, and then the connecting shell 1 is installed.

[0029] The connection housing 1 and the plug connector are fixed by utilizing the friction force generated by the contact between the top contact plate 7 and the plug connector housing. At the same time, a plurality of bosses 14 are fixed to the end of the top contact plate 7 away from the limit block 5, and the bosses 14 can further increase the installation stability between the two.

[0030] In the above structure, after pressing the pressing plate 6, the pressing plate 6 drives the limit block 5 and the top contact plate 7 to move downward. During the downward movement of the limit block 5, after the bottom of the limit plate hits the side of the double-headed locking bent rod 9, the double-headed locking bent rod 9 rotates along the horizontal axis 20, so that the double-headed locking bent rod 9 rotates upward.

[0032] When it is necessary to plug in the connecting shell 1, the push plate 11 is pressed to drive the moving rod 10 to move toward the through groove 2, and the moving rod 10 is abutted against the side of the double-headed locking bent rod 9, wherein the two ends of the double-headed locking bent rod 9 can respectively abut against the limit block 5 or the end face of the moving rod 10. As the moving rod 10 continues to move, the double-headed locking bent rod 9 can be driven to start rotating, and then the end close to the limit block 5 is moved out of the hook groove 8. After moving out of the hook groove 8, since a support rod 16 is connected to the other side of the limit block 5, the support rod 16 moves synchronously with the shaft sleeve 17. Then, after the limit block 5 is not affected by the clamping and limiting action of the double-headed locking bent rod 9, under the action of the elastic potential energy of the spring 18, the shaft sleeve 17 and the support rod 16 carry the limit block 5 to automatically move up and reset.
