[0033] When in use, place the terminal on the support 3, then rotate the pressure plate 9 to move it away from the top plate 8, and pull the pressure plate 9 to drive the top plate 8 close to the plug block 4. At this time, insert the lead into the hole 5 on the top of the plug block 4 and make it enter the top surface of the pressure plate 9, and then continue to move the lead to expose it from the back side of the top plate 8. At this time, reverse the pressure plate 9 to press the lead on the top plate 8, and then push the pressure plate 9 to drive the top plate 8 and the slide 7 to move toward the support 3, insert the plug-in end of the lead into the interior of the terminal, and then use the drive assembly to drive the pressure needle 2 to move downward to complete the plug-in of the lead and the terminal. Since the plug-in interface on the terminal is small, it is possible to avoid taking the lead and inserting it into the terminal, thereby improving the convenience and efficiency of plug-in.

[0034] Reference Figure 1 and Figure 2 The driving assembly includes a cylinder 10 and a mounting frame 11. The cylinder 10 is fixedly connected to the top of the machine body 1, the output end of the cylinder 10 is fixedly connected to the top surface of the mounting frame 11, and the pressure needle 2 is fixedly connected to the inside of the mounting frame 11.

[0035] The driving cylinder 10 can push out the installation frame 11, at which time the pressing pin 2 can be pushed out to complete the plug-in, and the mounting block 12 and the pressing pin 2 can be installed inside the installation frame 11 using the screw 13, which can facilitate the adjustment of the position of the pressing pin 2 and also facilitate the increase in the number of the pressing pins 2, thereby improving the applicability of the device.

[0036] Reference Figure 1 and Figure 3 Insertion plates 14 are provided on both sides of the top of the support 3 , and a plurality of slots 15 are provided on the top of the support 3 , and the two insertion plates 14 are both located inside the slots 15 .

[0037] By inserting the plug board 14 into the slot 15 at the top of the support 3, the position of the terminal can be restricted, thereby achieving the purpose of auxiliary positioning of the terminal, and by inserting the plug board 14 into different slots 15, the distance between the two plug boards 14 can be adjusted, thereby limiting the terminals of different sizes, thereby improving the practicality of the device.

[0038] Reference Figure 5 The cross section of the jack 5 on the side close to the top plate 8 is set to be circular, and the cross section of the jack 5 on the side away from the top plate 8 is set to be conical.

[0039] By setting the diameters on both sides of the jack 5 to be larger and smaller, that is, the diameter of the jack 5 away from the support 3 is larger than the diameter of the jack 5 close to the support 3, it is convenient to insert the lead wire into the interior of the jack 5, thereby improving the convenience of using the device.

[0040] Reference Figure 1 and Figure 4 The middle part of the top surface of the machine body 1 is rotatably connected with a connecting frame 17, the top of the connecting frame 17 is fixedly connected with a baffle 18, the middle part of the connecting frame 17 is fixedly connected with a cross bar 19, the outer wall of the cross bar 19 is rotatably connected with a push rod 20, the bottom of the push rod 20 is rotatably connected with a push plate 21, the bottom of the push plate 21 is slidably connected with the machine body 1, the middle part of the push plate 21 is slidably connected with a guide rod 22, one end of the guide rod 22 is fixedly connected with a support 3, and the outer wall of the guide rod 22 between the push plate 21 and the support 3 is sleeved with a spring 23. The middle part of the top surface of the machine body 1 is fixedly connected with a connecting seat 16, and the connecting seat 16 is rotatably connected with the connecting frame 17. A limit plate 24 is provided on the front side of the connecting frame 17, and the limit plate 24 contacts the connecting frame 17, and the limit plate 24 is fixedly connected with the machine body 1.

[0041] When the pressure plate 9 is close to the support 3, it will squeeze the baffle 18. At this time, the baffle 18 will rotate toward the support 3. The push rod 20 can make the push plate 21 slide toward the support 3 to compress the spring 23. When the pressure plate 9 is away from the support 3, the spring 23 will drive the push plate 21 away from the support 3, and then push the push rod 20 to lift the baffle 18, so that the connecting frame 17 is in contact with one side of the limit plate 24, so that the baffle 18 is in a disposal state, and then the baffle 18 is reset. At this time, when the lead is inserted into the socket 5, the moving lead can make its plug-in end rest on the baffle 18. Therefore, when multiple leads are plugged in at the same time, the plug-in ends of multiple leads can be in a flush state, thereby avoiding unevenness and reducing the quality of plug-in.

[0042] Working principle: When in use, first place the terminal on the support 3 and insert the plug plate 14 into the support 3. At this time, the position of the terminal can be guided and fixed to prevent it from moving. Then lift the pressure plate 9 to rotate it along the top side of the top plate 8 so that the two sides close to the plug block 4 are away from each other. Then pull the pressure plate 9 to drive the top plate 8 and the slide 7 to move, so that the top plate 8 of the pressure plate 9 is in contact with the plug block 4. At this time, insert the plug-in end of the lead into the socket 5 of the plug block 4, and then push the lead to pass through the socket 5 and enter the top of the top plate 8. When the plug-in end of the lead is exposed from the back side of the top plate 8, it will contact the baffle 18. Therefore, when multiple leads enter the top of the top plate 8, the length of the multiple lead plug-in ends extending from the top plate 8 can be the same. When the lead is placed, reverse the pressure plate 9 to press the lead against the top surface of the top plate 8. , and then push the pressure plate 9 to drive the top plate 8 and the slide 7 to slide along the slide rod 6 and approach the support 3. At this time, the plug-in end of the lead can be inserted into the interior of the terminal. At this time, the driving cylinder 10 drives the pressure needle 2 to move down. At this time, the plug-in connection between the lead and the terminal can be completed, and when the pressure plate 9 approaches the support 3, the baffle 18 will be squeezed. At this time, the baffle 18 will rotate toward the support 3 and drive the push rod 20 to squeeze the push plate 21. At this time, the push plate 21 will slide toward the support 3 along the guide rod 22 and compress the spring 23. When the plug-in is completed, the pressure plate 9 is moved close to the plug-in block 4. At this time, the spring 23 will push the push plate 21 to move it away from the support 3, and then push the push rod 20 to lift the baffle 18. Finally, the connecting frame 17 is fitted with one side of the limit plate 24, so that the baffle 18 is in a disposal state, thereby completing the resetting of the baffle 18.
