[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In this embodiment, front, back, left, right, up and down are represented by Figure 1 Describes the datum. Figures 1-5 , the utility model provides a technical solution:

[0023] A wiring device for an automatic power switch includes a conductive copper busbar 1 for installation as a conductive member within the automatic power switch. The upper surface of the conductive copper busbar 1 is provided with a plurality of connection ports 11. A transparent shell 2 fixedly connected to the conductive copper busbar 1 is installed above each connection port 11. Each upper surface of the transparent shell 2 is provided with a through-hole 21. An extrusion block 3 is slidably installed within each through-hole 21. The extrusion block 3 is located above the connection port 11. A vertical plate 22 is fixedly installed on the rear surface of the transparent shell 2. A tightening device 4 for securing a cable is installed on the front surface of each vertical plate 22. The transparent shell 2 is a shell made of an insulating material. The extrusion block 3 is in the shape of an "I" (Chinese character for "H"), and a reset spring 32 is fixedly installed between the extrusion block 3 and the transparent shell 2.

[0024] It should be noted that, combined with Figure 4 and Figure 5 The squeezing device 4 includes a squeezing block 41, which is located below the connecting port 11, and a squeezing spring 42 is fixedly installed between the rear surface of the squeezing block 41 and the front surface of the vertical plate 22. Two directional rods 43 are symmetrically fixedly installed on the rear surface of the squeezing block 41, and the directional rods 43 are both slidably connected to the vertical plate 22;

[0025] Before wiring, first push the extrusion block 41 to the rear by means of a screwdriver, so that it moves backward and avoids the position of the cable passing through the connecting port 11. During wiring, directly insert the cable into the transparent shell 2, so that the end of the cable passes over the position of the connecting port 11. Then, manually press down the extrusion block 3, and press the cable downward by means of the extrusion block 3, so that it is bent and passes through the connecting port 11. Then, remove the screwdriver used to push the extrusion block 41, and the extrusion block 41 moves forward under the action of the extrusion spring 42, so that the cable is bent forward again at the connecting port 11, and the cable is clamped and fixed. After clamping, the cable is in contact with the conductive copper bar 1, so that the wiring work is completed. Compared with the prior art, the wiring device is simple and fast, avoids the operation of tightening the bolt, and can improve the overall wiring efficiency.

[0026] In order to strengthen the clamping effect of the extrusion block 41 on the cable, the extrusion block 41 needs to be arranged in an L shape, so that the extrusion block 41 can clamp the cable at the connecting port 11, prevent it from being separated from the conductive copper bar 1, and ensure the wiring effect.

[0027] When pushing the extrusion block 41 backward by means of a screwdriver, recesses 411 are formed on the front surface of the extrusion block 41 to prevent the screwdriver from slipping and separating from the extrusion block 41. The end of the screwdriver can be inserted into the recess 411 to push the extrusion block 41 backward, so that the screwdriver does not slip and separate during the pushing process.

[0028] When the cable is bent and broken by means of the extrusion block 3, an arc-shaped slot 31 is formed through the front surface of the extrusion block 3. The bent cable is in the arc-shaped slot 31, so that the breaking condition can be avoided.

[0029] Finally, when the conductive copper bar 1 is installed and in contact with the electrical connecting piece in the power automatic transfer switch, a conductive contact surface is arranged, as shown in Figure 1 or Figure 2 The copper seat 12 is fixedly installed in the conductive copper bar 1. The lower surface of the copper seat 12 is in the same horizontal plane as the lower surface of the conductive copper bar 1. The copper seat 12 can be in contact with the electrical connecting piece in the power automatic transfer switch to increase the conductive contact surface, so as to ensure the conductive effect.
