The top of the second spring 11 is connected to the telescopic plate 12, and a fixed block 13 is provided on the top of the front end of the telescopic plate 12. The second spring 11 can pop out the fixed block 13 at the top of the front end of the telescopic plate 12 from the second telescopic slot 10 through tension; the female connector 1 is provided with slots 4 at the upper and lower ends of the connector 3, and a toggle plate 14 is provided at the rear end of the telescopic plate 12. By toggling the toggle plate 14, the toggle plate 14 can drive the telescopic plate 12 to push the plug-in block 9 out of the first telescopic slot 7 and plug it into the female connector 1 opened around the connector 3. The slot 4 is provided with a fixed groove 5 at the inner top of the slot 4, and the second spring 11 at the top of the plug-in block 9 in the slot 4 can bounce the fixed block 13 at the top of the front end of the telescopic plate 12 into the fixed groove 5 through tension to fix the plug-in block 9; the male connector 2 is provided with a closed ring groove 17 around the outer side of the plug-in block 9, and a closed ring 18 is provided in the closed ring groove 17. The closed ring 18 can slide in the closed ring groove 17 so that the closed ring 18 closes the through hole 16 to prevent the operator from accidentally touching the toggle plate 14 at the top of the rear end of the telescopic plate 12; the front bottom of the closed ring 18 is connected to the first connecting plate 19, and the front end of the bottom of the first connecting plate 19 is connected to the limit block 20.

[0024] In actual use, when the female connector 1 is connected to the male connector 2, the wire rod 27 in the middle of the front end of the male connector 2 is first inserted into the connector 3 in the middle of the front end of the female connector 1, and then the pressing plate 25 is pressed to drive the clamping block 23 to squeeze the third spring 22 through the second connecting plate 24 and shrink it into the third telescopic groove 21, and at the same time, the closed ring 18 is pushed outward. At this time, the closed ring 18 starts to push the toggle plate 14 through the limit block 20 connected to the first connecting plate 19 at the bottom, so that the toggle plate 14 synchronously pushes the telescopic plate 12 to drive the plug-in block 9 out of the first spring 8. When the front end of the closed ring 18 reaches the front end of the closed ring groove 17, the second spring 11 at the bottom of the telescopic plate 12 uses tension to bounce the fixing block 13 at the top of the front end of the telescopic plate 12 into the fixing block 13 opened on the inner top of the slot 4, and the plug-in block 9 is fixed. The plug-in block 9 limits the connection between the female connector 1 and the male connector 2. When the telescopic plate 12 is extended and retracted upward, the toggle plate 14 is driven to move upward. At this time, the limiting groove 15 at the bottom of the toggle plate 14 is parallel to the limiting block 20. The limit block 20 can be inserted into the limit groove 15 to limit the telescopic plate 12. Then, the pressing plate 25 is released, and the third spring 22 at the bottom of the block 23 bounces the block 23 into the clamping groove 26 to complete the connection limit between the female connector 1 and the male connector 2. At the same time, the closing ring 18 begins to close the through hole 16 to prevent the operator from accidentally touching the toggle plate 14. When the connection between the female connector 1 and the male connector 2 is removed, the pressing plate 25 is pressed again to make the pressing plate 25 drive the block 23 to retract into the third telescopic groove 21 through the second connecting plate 24, and then toggle back. The closed ring 18 is moved, and the closed ring 18 opens the closure of the through hole 16, allowing the toggle plate 14 to leak out. Then, by pressing the toggle plate 14, the toggle plate 14 drives the telescopic plate 12 to squeeze the second spring 11, so that the fixed block 13 connected to the top of the front end of the second spring 11 is disengaged from the fixed groove 5 at the top of the inner side of the slot 4 and shrinks into the second telescopic groove 10. At this time, the second telescopic groove 10 connected to the inner side of the plug-in block 9 shrinks the plug-in block 9 into the first spring 8 through the shrinkage force, so that the wire rod 27 can be pulled out of the connector 3, and the female connector 1 and the male connector 2 are separated.
