[0019] The general wiring device for electric power engineering is a common wiring device, and the fastening capacity is not good. However, the connection of the cable is the weakest place, and after the cable is subjected to tension, the wiring part is easy to separate to cause short circuit, and re-inspection and connection are needed, which affects the work efficiency.
[0020] In order to solve this problem, please refer to Figures 1-5 A wiring device for electric power engineering, comprising: a lower protective shell 10 and an upper protective shell 11, arc-shaped grooves 12 are formed on the short edges of the lower protective shell 10, arc-shaped grooves 12 are also formed on the bottom of the short edges of the upper protective shell 11, the arc-shaped grooves 12 on the lower protective shell 10 and the upper protective shell 11 correspond to each other, and the arc-shaped grooves 12 on the lower protective shell 10 and the upper protective shell 11 form a circular hole after splicing, a plurality of wedge-shaped blocks 13 are fixedly arranged on the outer edges of the arc-shaped grooves 12 on the lower protective shell 10 and the upper protective shell 11, the plurality of wedge-shaped blocks 13 are arranged in a ring shape around the circular hole, internal threads 14 are arranged on the outer surfaces of the plurality of wedge-shaped blocks 13, a cylinder 15 is arranged on each of the plurality of wedge-shaped blocks 13, an external thread 16 is arranged at one end of the inner surface of the cylinder 15, the opening of the cylinder 15 gradually decreases from one end to the other end, and the external thread 16 is located at the larger end of the opening of the cylinder 15.
[0021] At least one pair of fixing devices 20 is arranged between the lower protective shell 10 and the upper protective shell 11, each fixing device 20 comprises a shell 21 and a conductive copper sheet 24, wire insertion ports 22 are formed on the two sides of the shell 21, a threaded rod 23 is rotatably arranged in the shell 21, and the conductive copper sheet 24 is slidably arranged in the shell 21.
[0022] In use, first, the end of the two cables to be connected together, respectively from the two small opening end of the cylinder 15, the cable outer insulation layer is stripped, the copper wire of the two cables are inserted into the wire insertion port 22 of the fixing device 20, rotate the threaded rod 23, the threaded rod 23 drives the conductive copper sheet 24 to move upward, the conductive copper sheet 24 extrudes the copper wire upward, and extrudes and fixes it in the wire insertion port 22. After connecting the two cables together, combine the lower protective shell 10 and the upper protective shell 11 together, so that the fixing device 20 is located therein, and the cable is located in the arc-shaped groove 12, surrounded by the wedge block 13 in the middle, finally pull back the cylinder 15 previously sleeved on the cable, so that the external thread 16 on the inner surface of the cylinder 15 is engaged with the internal thread 14 on the wedge block 13, rotate the cylinder 15 to move the cylinder 15 to the end of the cable through the internal thread 14. The continuous forward movement of the cylinder 15 will gradually extrude the end of the wedge block 13 due to the gradual reduction of the opening of the cylinder 15, so as to bend and deform inward, fix the cable in the wedge block 13, and fix and connect the lower protective shell 10 and the upper protective shell 11 together. Through the fixation of the cable, it will not affect the connection end of the fixing device 20 when subjected to tension.
[0023] In the specific implementation process, as shown in Figure 3 and Figure 5 A pair of fixing grooves 101 are formed in the lower protective shell 10, and a limiting groove 102 is formed on both sides of the fixing groove 101. A limiting block 103 is slidably arranged in the limiting groove 102. A first elastic member 104 is fixed on one side of the limiting block 103. The first elastic member 104 is fixedly connected with the inner wall of the limiting groove 102 away from the limiting block 103. A fixing hole 29 is formed on both sides of the long side of the shell 21. A push plate 105 is fixed on the limiting block 103. The limiting block 103 is inserted into the fixing groove 101 through the limiting groove 102. The side of the limiting block 103 inserted into the fixing groove 101 is in the shape of a triangular column. The side of the triangular column of the limiting block 103 is inclined upward. The push plate 105 penetrates through the limiting groove 102.
[0024] In use, after the fixing device 20 connects the two ends of the cable together, the fixing device 20 is inserted into the fixing groove 101. When it is about to reach the bottom of the fixing groove 101, the bottom of the housing 21 will press the inclined surface of the limiting block 103, causing it to move into the limiting groove 102 and press the first elastic member 104. When the housing 21 reaches the bottom of the fixing groove 101, the fixing holes 29 on both sides of the housing 21 are at the same height as the limiting block 103. The first elastic member 104 pushes the limiting block 103 into the fixing hole 29 to fix the fixing device 20, so that it will not shake when it is between the lower protective shell 10 and the upper protective shell 11, reducing the possibility of loosening at the connection. When it is necessary to remove the fixing device 20, the lever 105 is turned. The lever 105 drives the limiting block 103 to move into the limiting groove 102, so that it is pulled out from the fixing hole 29, and the fixing device 20 can be removed.
[0025] In the specific implementation process, such as Figure 4 As shown, a knob 25 is fixedly provided on the top of the threaded rod 23, a serrated strip 26 is provided on the upper surface of the conductive copper sheet 24, a serrated strip 27 is provided on the top of the housing 21, the serrated strip 26 and the serrated strip 27 are arranged in a staggered manner, and a second elastic member 28 is fixedly provided at the bottom of the housing 21, the top of the second elastic member 28 is fixedly connected to the bottom of the conductive copper sheet 24.
[0026] When the threaded rod 23 needs to be rotated, the knob 25 is turned by hand. The rotation of the knob 25 drives the threaded rod 23 to rotate together, making it more convenient to use. When the conductive copper sheet 24 squeezes and fixes the copper wire, the first serrated bar 26 and the second serrated bar 27 clamp it in the middle, making the clamping and fixing of the copper wire more stable and preventing slippage that could cause it to fall off. The second elastic element 28 applies a continuous upward pushing force to the conductive copper sheet 24, reducing the slight rotation of the threaded rod 23 due to vibration, reducing the clamping force, and thus preventing the connection from breaking.
