[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a connector. Figure 1 and Figure 2A connector includes a connection column 1 and a plurality of cutters 2. The connection column 1 is provided with a plurality of connection grooves 11 for connecting wires to be inserted into. The plurality of cutters 2 are slidably connected to the connection column 1, and the plurality of cutters 2 are slidably extended into or extended from the corresponding connection grooves 11. When the cutters 2 are extended into the connection grooves 11, the plurality of cutters 2 are evenly distributed in the connection grooves 11, and the distribution direction of the cutters 2 located in the same connection groove 11 is parallel to the extension direction of the connection groove 11. The cutter 12 is provided with a blade 12 for inserting the metal part of the connection wire into. The cutter 2 is machined to form a cutting portion 21, which is located above the blade 12, and is located on opposite sides of the blade 12. The cutting portion 21 is inclined downward in a direction close to the blade 12, and is used to cut the insulation part of the connection wire; the cutter 2 is machined to form a blunt portion 22, which is located on the inner wall of the blade 12, and the cutter 2 abuts against the metal part of the connection wire through the blunt portion 22. The cutting part 21 cuts the insulating part of the connecting wire so that the metal part of the connecting wire is inserted into the blade 12 and abuts against the blunt part 22. A plurality of conductive sheets 7 are fixed on the connecting column 1. The position and number of the conductive sheets 7 correspond to the position and number of the connecting grooves 11. The conductive sheets 7 are located in the corresponding connecting grooves 11. The conductive sheets 7 abut against a plurality of cutters 2 in the connecting grooves 11. The sliding direction of the plurality of cutters 2 is perpendicular to the length direction of the connecting grooves 11, and adjacent cutters 2 are arranged at intervals.

[0033] Reference Figure 1 and Figure 2 A pressure cap 3 is hingedly connected to the connecting column 1. The pressure cap 3 is positioned by friction with the connecting column 1. The rotation axis of the pressure cap 3 is parallel to the distribution direction of the connecting groove 11. The pressure cap 3 rotates closer to or away from the connecting groove 11. The pressure cap 3 is used to compress the connecting wire so that the metal part of the connecting wire is stuck in the blade 12 and abuts against the cutter 2, which is conducive to maintaining the stability of the circuit.

[0034] Reference Figure 2 and Figure 3 The connecting column 1 is slidably connected with a connecting portion 4, and the sliding direction of the connecting portion 4 is parallel to the sliding direction of the cutter 2. When the cutter 2 is located in the connecting groove 11, the connecting portion 4 is located on the side of the cutter 2 close to the bottom of the connecting groove 11. The cutters 2 are fixedly connected to the connecting portion 4. The movement of the connecting portion 4 drives the cutters 2 to move simultaneously. A positioning member 5 is fixed on the connecting column 1, and the positioning member 5 is used to fix the cutter 2 and the connecting portion 4.

[0035] Reference Figure 1 and Figure 2The positioning member 5 is a thermal expansion and contraction block 51, which is located on one side of the connecting portion 4 close to the connecting groove 11. The thermal expansion and contraction block 51 is fixedly connected to one end of the cutter 2 close to the connecting groove 11 through the connecting portion 4. The opposite ends of the thermal expansion and contraction block 51 distributed parallel to the sliding direction of the cutter 2 are respectively fixedly connected to the connecting column 1 and the connecting portion 4. When the thermal expansion and contraction block 51 is not deformed, the cutter 2 is located in the connecting groove 11.

[0036] Reference Figure 1 and Figure 2 The connecting column 1 is provided with a limiting groove 13, the position and number of the limiting groove 13 correspond to the position and number of the cutters 2, the limiting groove 13 is connected to the connecting groove 11, and the inner wall of the limiting groove 13 abuts against the cutter 2 to limit the position of the cutter 2, thereby preventing the cutter 2 from deviating from the moving track during the movement. In this embodiment, the number of the connecting grooves 11 is 2, and the number of the cutters 2 is 4.

[0037] When using the connector to connect the connecting wires, the ends of the two connecting wires to be connected are respectively inserted into the connecting grooves 11, and the pressure cover 3 is rotated to press the connecting wires tightly, so that the cutter 2 cuts the insulating layer of the connecting wire and abuts against the metal part of the connecting wire, so that the two connecting wires are conductive.

[0038] As the usage time increases, if the circuit is overloaded or short-circuited, the temperature of the connection between the connecting wire and the cutter 2 rises, causing the thermal expansion and contraction block 51 to expand due to the heat, driving the connecting part 4 to move away from the connecting groove 11, and then driving the cutter 2 to move out of the connecting groove 11 and separate from the metal part of the connecting wire, making it easier to disconnect the connecting wire.

[0039] Reference Figure 1 and Figure 2 A support frame 6 is slidably connected to the connecting column 1, and the sliding direction of the support frame 6 is parallel to the sliding direction of the connecting part 4. The support frame 6 and the cutter 2 are respectively located on opposite sides of the connecting part 4, and the support frame 6 is fixedly connected to the connecting part 4. The support frame 6 is fixedly connected to the thermal expansion and contraction block 51 through the connecting part 4. The support frame 6 is located on the side of the connecting part 4 away from the thermal expansion and contraction block 51. The movement of the connecting part 4 drives the support part to slide into or out of the end of the connecting column 1 away from the connecting groove 11. The support frame 6 extends out of the connecting column 1 to support the connecting column 1, thereby increasing the contact area between the connecting column 1 and the air and improving the heat dissipation efficiency of the connector.

[0040] As the usage time increases, if the circuit is short-circuited or overloaded, the temperature of the contact point between the cutter 2 and the metal part of the connecting wire rises, thereby causing the temperature of the entire connector to rise. The heat-sensitive deformable part deforms with the temperature rise, driving the connecting part 4 to move, and then driving the support frame 6 and the cutter 2 to move away from the connecting groove 11, so that the cutter 2 moves away from the metal part of the connecting wire and the circuit is disconnected. The support frame 6 moves and extends out of the connecting column 1 to accelerate the heat dissipation of the connector, making it easier for the staff to find that the connector is disconnected.

[0041] When the temperature at the connector drops, the thermal expansion and contraction block 51 recovers its shape, allowing the cutter 2 to re-enter the connection groove 11 and abut against the metal part of the connection line, thereby reducing the contact between the staff and the connection line and improving safety.

[0042] The implementation principle of a connector in an embodiment of the present application is: during the actual installation process, the connecting wire is inserted into the connecting groove 11, and the pressure cover 3 is rotated. The connecting wire is pressed against the cutter 2 through the pressure cover 3. The cutter 2 cuts the insulating part of the connecting wire and the metal part is inserted into the blade 12. Several cutters 2 simultaneously abut the metal part of the connecting wire, and the contact area between the connecting wire and the connector is improved, thereby improving the stability of the connection between the connector and the connecting wire.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
