Embodiment: Refer to a power distribution cabinet lead shown in Figures 1-5, which includes a lead box 1, a lead cover 2 and two front and rear clamping plates 3. The lead cover 2 is arranged on the top of the lead box 1, and the lead cover 2 is There are two fixed plates 4 fixedly connected to the bottom. The opposite sides of the two fixed plates 4 are fixedly connected with protective parts 5. A pressure sensor 9 is provided in the protective part 5. One side of the protective part 5 and the pressure sensor 9 is connected to the same The fixed plate 4 is fixedly connected, the top of the lead cover 2 is fixedly connected to a collector box 6, both sides of the collector box 6 are fixedly connected to an alarm module 7, and the top two sides of the alarm module 7 are respectively provided with a switch 11 and an alarm 12 , apply the existing distribution and installation technology of lead to connecting wire, the connecting wire runs through the lead box 1, penetrates into the lead box 1, and is electrically connected to the connection end, and then the two front and rear clamping plates 3 on the lead cover 2 are respectively The clamp is connected to the outside of the connecting wire, the connecting wire is limited and fixed, and then the lead box 1 and the lead cover 2 are installed to complete the distribution arrangement of multiple connecting wires by the lead device.

As shown in Figure 2, two fixed plates 4 are located at the bottom of the lead cover 2 and are distributed in parallel. The front and rear clamping plates 3 are vertically connected to the protective parts 5. The tops of the two front and rear clamping plates 3 are connected to the lead cover 2 through a plurality of silicone strips 15. For fixed connection, when the lead is used to distribute the connection between the connecting wire and the connection terminal in the power distribution cabinet, the two front and rear clamping plates 3 are vertically connected to the outside of the connecting line to realize the fixation of the outside of the connecting wire in the 3 pairs of front and rear clamping plates. The silicone strip 15 is used for elastic connection between the front and rear clamping plates 3 and the lead cover 2 .

As shown in Figure 3, the protective piece 5 is located in the middle of the fixed plate 4 and the front and rear clamping plates 3. The protective piece 5 has a rectangular tubular structure and is made of rubber material. The protective piece 5 is convenient for protecting its internal components. For support, the front and rear clamping plates 3 are installed vertically on the bottom of the lead cover 2 for use. The elastic characteristics of the rubber material facilitate the elastic movement of the front and rear clamping plates 3.

As shown in Figure 3, the other side of the pressure sensor 9 is fixedly connected to a force spring 8. The force spring 8 is fixedly connected to the fixed plate 4. The force spring 8 has a wave-shaped structure. The force spring 8 is located on the protective member 5. In the middle position inside, the force-bearing spring 8 facilitates the elastic connection between the fixed plate 4 and the front and rear clamping plates 3, and is used for force transmission, so that when the front and rear clamping plates 3 are under tension, the protective piece 5 can be squeezed to make the internal The force spring 8 is compressed and shortened under force, and the pressure sensor 9 detects the pressure received.

As shown in Figure 4, the pressure sensor 9 is connected to the alarm module 7 through the transmission line 10, and the switch 11 is electrically connected to the alarm 12. The alarm 12 is set with a pressure alarm value. Using existing pressure detection technology and alarm technology, the pressure sensor 9 is used to detect the pressure between the force spring 8 and the front and rear clamping plates 3 in real time. When the fixed connection line of the front and rear clamping plates 3 is subjected to tension, the detection value of the pressure sensor 9 will become larger. When the detection value is greater than When the pressure reaches the alarm value, the alarm 12 will sound the whistle to perform alarm work.

As shown in Figure 5, the two alarm modules 7 are electrically connected to the power collection box 6 through the power cord 13. The power collection box 6 is provided with a battery 14. The power collection box 6 is used to transmit the power of the battery 14, so that through the power collection The box 6 and the power cord 13 transmit the power inside the battery 14 to the two alarm modules 7 to perform alarm work.

This practical working principle:

When using the lead of the power distribution cabinet, first apply the existing lead installation technology to install the lead box 1, and install the battery 14 in the collector box 6, so that the collector box 6 can be connected to two pairs through the power cord 13 The alarm module 7 supplies power, and then according to the wiring arrangement, pass the connecting wire through the lead box 1 into the middle of the interior of the lead box 1, and connect it to the connection end in the lead box 1, and then connect the front and rear clamps at the bottom of the lead cover 2 3 are respectively stuck on the outside of the connecting wire, limit and fix the outside of the connecting wire, install the lead box 1 and the lead cover 2, open the switches 11 on the two alarm modules 7, and clamp the front and rear plates 3 of the alarm module 7 The tension protection alarm on the wire guide completes the assembly of the wire lead; during the use of the wire lead, when the outside of the connecting wire is pulled by an external force, the connecting wire will drive the external front and rear clamping plates 3 to squeeze against the protective piece 5, causing the internal The pressure sensor 9 transmits force to the force spring 8. The force spring 8 and the protective member 5 are elastically compressed. The pressure on the pressure sensor 9 and the force spring 8 increases. By applying the existing sensor The pressure detection technology and detection alarm technology enable the pressure sensor 9 to transmit the detected data to the alarm module 7 through the transmission line 10. When the detection value is greater than the pressure alarm value set in the alarm 12, the alarm 12 will sound the alarm and sound the alarm. External users will alarm and remind, reduce the pulling of the connecting wire, avoid the breakage of the connecting wire and the connecting terminal, protect the connecting wire and the connecting terminal, and increase the safety of the use of the wire lead.

Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it is still possible to modify the technical solutions recorded in the foregoing embodiments, or to perform equivalent substitutions on some of the technical features.
