[0031] Example

[0032] See also Figure 1-7As shown, the utility model provides a technical solution of an insulation piercing connector: it includes a lower shell 1 and an upper shell 2 fixed to the upper port of the lower shell 1 by ultrasonic welding, both ends of the lower shell 1 are integrally formed with insertion holes 101 for inserting cables, and the lower shell 1 and the upper shell 2 are equipped with a piercing mechanism 3 for piercing the insulation layer of the cable, and the piercing mechanism 3 includes a piercing core 31, two return buckles 32 and a pressing assembly, and the piercing core 31 is fixed to the lower end surface inside the lower shell 1, and the two return buckles 32 are connected to the lower shell 1. The inner wall of the shell 1 is slidably connected, and the pressing assembly is installed on the upper shell 2 to press the two return buckles 32. The two cables are respectively inserted from the insertion holes 101 at both ends of the lower shell 1, and then the pressing assembly is pressed downward. The pressing assembly pushes the two return buckles 32 to move downward, and the cable is pressed onto the piercing core piece 31. The piercing structure of the piercing core piece 31 pierces the surface of the cable. The two cables are conductively connected through the piercing core piece 31, and the two return buckles 32 are clamped and limited by the rectangular groove at the lower side of the piercing core piece 31.

[0033] Auxiliary mechanisms 4 for sealing and limiting the cable when inserted are installed on both sides of the insertion hole 101 on the lower shell 1. The auxiliary mechanism 4 includes two wire clips 41 and two rubber-coated structures 42. The two wire clips 41 are clamped on both sides of the interior of the lower shell 1 to limit the cable inserted into the insertion hole 101. The inserted cable is clamped by the two wire clips 41 to prevent the cable from withdrawing. The two rubber-coated structures 42 are installed on the outside of the insertion hole 101 on both sides of the lower shell 1 for sealing after the cable is inserted, so that the cable insertion position can be effectively sealed, which is beneficial to the transfer of copper and aluminum cables.

[0034] The pressing assembly includes two sockets 5 and two pressing blocks 6. The two sockets 5 are symmetrically distributed on the upper shell 2. The two pressing blocks 6 are inserted into the two sockets 5 to press the two return buckles 32. The two pressing blocks 6 are coated with rubber to achieve the sealing of the upper shell 2, which is beneficial to the transfer of copper and aluminum cables. When the cable is pierced and connected, the two return buckles 32 are pressed by the two pressing blocks 6, and the voltage is pressed into the piercing core 31 through the two return buckles 32.

[0035] The lower ends of the two pressing blocks 6 are integrally formed with protrusions that match the recesses at the upper ends of the two return buckles 32, ensuring that the two pressing blocks 6 can effectively squeeze the two return buckles 32 to move downward.

[0036] The piercing core piece 31 and the two return buckles 32 are mounted in the card slots and card pieces to ensure that after the cable piercing is completed, the two return buckles 32 can always press the cable onto the piercing core piece 31 .

[0037] A baffle 21 is integrally formed on the lower end surface of the upper shell 2, and slide grooves matching the baffle 21 are integrally formed on both sides of the interior of the lower shell 1, further increasing the sealing effect inside the lower shell 1 and blocking the two cables, making it easier for staff to know that the cables are inserted in place.

[0038] The two rubber-encapsulating structures 42 are multi-level and can be adapted to the sealing of cables of different specifications.

[0039] In this embodiment, when it is necessary to connect two cables, it is only necessary to insert the insertion hole 101 into the interior of the lower shell 1, and the cable will pass through the two return buckles 32 and the piercing core piece 31, and the cable will be clamped by the two wire clamping buckles 41 to prevent the cable from withdrawing. When the front end of the cable touches the baffle 21, press the corresponding one of the two pressing blocks 6, and the pressing block presses the corresponding one of the two return buckles 32 to move downward, and the return buckle presses the cable onto the piercing core piece 31, and pierces the surface of the cable through the piercing structure of the piercing core piece 31, and then the same method is adopted to insert another cable. The two cables are conductively connected through the piercing core piece 31, and the two return buckles 32 are clamped and limited by the rectangular groove at the bottom side of the piercing core piece 31. The device does not require stripping to connect the two cables, retains the insulation layer of the cable, improves the insulation of the cable and the insulation piercing connector, and is simple to operate, improves the use efficiency, and is suitable for multi-diameter cables, as well as the connection of copper and aluminum cables.
