This solution can quickly complete the connection of the cable while ensuring insulation safety, eliminate the conventional insulation treatment method of tape wrapping, and also has a phase sequence marking function to avoid confusion of personnel during subsequent use. However, in the above solution, when the slot is not fully filled with wires, some slots with unconnected wires are directly exposed to the outside, increasing the risk of external dust and humid gas invading the slot. Once the dust and humid gas enter the slot, they will directly affect the conductive sheet inside the slot, resulting in oxidation, corrosion, etc. of the conductive sheet, thereby weakening the stability and reliability of the electrical connection. Therefore, it is necessary to provide a polymer insulating protection wire clamp to solve the above problems.

The following will describe the present application in detail with reference to the accompanying drawings and in combination with the embodiments. In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application. As shown in Figures 1-5, the present application provides a polymer insulated protection wire clamp, including: a housing 1 and a plugging component 7. A plurality of wire insertion holes 2 are provided on one side of the housing 1, and a wiring hole 6 is provided on the other side of the housing 1. First conductive sheets 8 are embedded and installed on the inner walls of the plurality of wire insertion holes 2, and a second conductive sheet 9 is embedded and installed on the inner wall of the wiring hole 6. The second conductive sheet 9 and the first conductive sheet 8 are electrically connected. The plugging component 7 includes a moving plate 71 that can move in the vertical direction. A plurality of installation grooves 72 are provided inside the moving plate 71. A plugging plate 75 is provided inside the installation groove 72. The bottom end of the plugging plate 75 is semicircularly arranged and is adapted to the wire insertion hole 2. When there is no wire connected to some of the wire insertion holes 2, the plugging plate 75 can block the wire insertion hole 2. A spring 74 is installed inside the installation groove 72. The two ends of the spring 74 are fixedly connected to the inner wall of the installation groove 72 and the plugging plate 75 respectively, providing the function of resetting the plugging plate 75. A plurality of arc-shaped grooves 76 are provided inside the moving plate 71 and are respectively communicated with the plurality of installation grooves 72. Among them, the positions of the plurality of arc-shaped grooves 76 correspond to the positions of the plurality of wire insertion holes 2 one by one. In this embodiment, by inserting the main line into the wiring hole 6 and inserting a plurality of branch lines into the plurality of wire insertion holes 2 respectively, through the electrical connection between the first conductive sheet 8 and the second conductive sheet 9, the power transmission and circuit connection between the main line and the branch lines can be realized. When the branch line is plugged in, by controlling the downward movement of the moving plate 71, when there is a wire connected to the wire insertion hole 2, the plugging plate 75 is blocked by the wire and contracts into the installation groove 72. As the moving plate 71 continues to move, until the arc-shaped groove 76 abuts against the wire, the connected wire can be fixed above the first conductive sheet 8 to ensure the stability of the wire connection. When there is no wire connected to some of the wire insertion holes 2, the plugging plate 75 at the corresponding position is not blocked, and under the elastic force of the spring 74, the plugging plate 75 abuts against the inner wall of the wire insertion hole 2, thereby blocking the wire insertion hole 2 to form a seal, reducing the possibility of dust and moisture entering the wire insertion hole 2, and improving the stability and reliability of the electrical connection.Among them, both the housing 1 and the plugging component 7 are made of high-strength polymer materials, having excellent insulation performance and mechanical strength, which can effectively isolate the current, prevent current leakage or short circuit, and play a certain protective role. As shown in Figure 4, a sliding groove is provided on the inner wall of the installation groove 72, and a sliding block 73 is installed on the outer side of the plugging plate 75. The plugging plate 75 and the sliding block 73 can be integrally formed, and the sliding block 73 is slidably connected to the sliding groove. In this embodiment, by providing the sliding block 73 and the sliding groove, the movement track of the plugging plate 75 can be restricted. As shown in Figure 3, a reserved groove communicating with a plurality of wire insertion holes 2 is provided inside the housing 1, and the moving plate 71 is slidably connected to the reserved groove. In this embodiment, restricting the movement track of the plugging component 7 ensures that the moving plate 71 can stably slide in the vertical direction. As shown in Figures 1-3, a screw rod 3 is threadedly connected to the top of the housing 1, the bottom end of the screw rod 3 is rotatably connected to the moving plate 71, and a knob 4 is installed at one end of the housing 1 away from the moving plate 71. In this embodiment, by rotating the knob 4, the screw rod 3 is controlled to rotate, thereby realizing the movement of the moving plate 71 in the vertical direction. As shown in Figure 5, a connecting rod 5 is provided at the top of the housing 1, the connecting rod 5 is L-shaped, the screw rod 3 passes through the connecting rod 5 and is rotatably connected to the connecting rod 5, an arc-shaped notch is provided at the end of the connecting rod 5, and a limiting groove communicating with the wiring hole 6 is provided at the top of the housing 1. The connecting rod 5 is slidably connected to the limiting groove. In this embodiment, when the moving plate 71 moves in the vertical direction, it can control the synchronous movement of the connecting rod 5, that is, when the plugging component 7 fixes the branch line connected to the wire insertion hole 2, the connecting rod 5 can use its arc-shaped notch to fix the main line above the second conductive sheet 9 at the same time, thereby realizing the power transmission and circuit connection between the main line and the branch line.Working principle: Insert the main line into the wiring hole 6, and insert multiple branch lines into multiple wiring holes 2 respectively. By controlling the downward movement of the moving plate 71, when there is a line connected to the wiring hole 2, the blocking plate 75 is blocked by the line and contracts into the installation groove 72. As the moving plate 71 continues to move until the arc groove 76 abuts against the line, the connected line can be fixed above the first conductive sheet 8 to ensure the stability of the line connection. When there is no line connected to some of the wiring holes 2, the corresponding blocking plate 75 will not be blocked, and under the elastic force of the spring 74, the blocking plate 75 abuts against the inner wall of the wiring hole 2, thereby blocking the wiring hole 2 to form a seal, reducing the possibility of dust and moisture entering the wiring hole 2. While the moving plate 71 moves, control the connecting rod 5 to move synchronously. The connecting rod 5 can use its arc-shaped notch to fix the main line above the second conductive sheet 9 at the same time, so as to realize the power transmission and circuit connection between the main line and the branch lines. The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
