Description

Technical Field

[0001] The utility model belongs to the technical field of wiring terminals, and particularly relates to a flexible and convenient through-wall wiring terminal. Background Art

[0002] A wiring terminal is an electrical component used to connect, fix, and protect cables or wires. It usually consists of a metal contact part (for conducting electricity) and an insulator (usually plastic) housing. The metal contact part is designed with holes or grooves for the wire to be inserted and fixed through a fastening mechanism (such as a screw) to achieve a safe and reliable electrical connection. A high-voltage through-wall wiring terminal is a specially designed wiring terminal for passing through walls or partitions and safely transmitting electricity in a high-voltage environment. Such terminals can withstand high voltages and currents while ensuring good insulation performance, preventing the generation of electric arcs and the risk of electrical fires. They usually have a higher insulation level and mechanical strength. Existing through-wall wiring terminals fix the wiring on the terminal by twisting multiple bolts. When installing and disassembling, it is necessary to turn and adjust multiple bolts in sequence, which is very troublesome, time-consuming, and laborious. Therefore, there is the drawback of cumbersome installation.

[0003] For example, the utility model with the publication number CN219739327U discloses a multi-layer stepped through-wall wiring terminal row. The insulating housing is also provided with a plurality of limit holes, and each limit hole is provided with a limit screw; each conductive tube is provided with a limit bayonet, and one end of the limit screw is fixed in the limit bayonet. In the solution of this patent, it is necessary to use tools (such as a screwdriver) to tighten multiple bolts one by one, increasing the installation time and labor cost. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a flexible and convenient through-wall wiring terminal, which uses a pressing plate to quickly fix the wiring. Only pressing operation is required without additional tools, greatly improving the efficiency. When adjustment or maintenance is needed, the wiring can be released and re-fixed more quickly.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A flexible and convenient wall-piercing terminal, including a mounting plate, two sliding plates corresponding to each other in the up and down positions are slidably connected inside the mounting plate. Five docking cylinders are arranged on the lower side of the upper sliding plate, and five fixing columns are arranged on the upper side of the lower sliding plate. The five fixing columns are respectively installed in cooperation with the adjacent five docking cylinders. Wiring pieces are fixedly sleeved on the outer arc surfaces of the five fixing columns. A plurality of avoidance openings corresponding to the positions of the wiring pieces are opened inside the mounting plate. A quick locking mechanism is arranged on the front side of the mounting plate. The quick locking mechanism includes two telescopic columns corresponding to each other in the left and right positions arranged on the front side of the mounting plate. Rotating frames are arranged on the telescopic ends of the two telescopic columns. Two connecting frames are rotatably connected inside each of the two rotating frames. Rotating seats are respectively arranged on the left and right sides of the two sliding plates. The rear ends of the four connecting frames are respectively rotatably connected inside the adjacent rotating seats. An elastic driving unit is arranged between the rotating frame and the mounting plate, and a linkage assembly is arranged between the two rotating frames. The elastic driving unit includes springs arranged between the rotating frame and the mounting plate. The two springs are respectively sleeved on the outer arc surfaces of the corresponding telescopic columns. The linkage assembly includes a pressing plate arranged between the two rotating frames.

[0006] As a further improvement of the present utility model, mounting holes are opened at the four corners of the mounting plate.

[0007] As a further improvement of the present utility model, an anti-slip pad is bonded to the front side of the pressing plate.

[0008] As a further improvement of the present utility model, a protective frame plate is arranged on the rear side of the mounting plate, and all five wiring pieces are located inside the protective frame plate.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] First, by pressing the pressing plate, the rotating frames on both sides move backward, causing the connecting frames on both sides inside them to rotate and expand, thereby driving the fixing columns and docking cylinders on the two sliding plates to move away from each other. At this time, the springs are in a compressed state. Then, the installer inserts the mounting rings on the cable onto the fixing columns, and then releases the pressing plate. At this time, the springs quickly rebound, driving the two sliding plates to quickly approach each other. The fixing columns slide into the inside of the docking cylinders to fix the cable. Using the pressing plate to quickly fix the wiring, only pressing operation is required, without additional tools, greatly improving the efficiency. When adjustment or maintenance is needed, the wiring can be released and re-fixed more quickly.

[0011] Second, during the process of the installer pressing the pressing plate, the anti-slip pad can effectively increase the friction between the human hand and the pressing plate, avoiding the phenomenon of hand slipping.

[0012] Third, the wiring pieces on the fixing columns can be connected to external wires to facilitate the installer to connect the conductive circuit, and the frame plate can provide a protective shielding effect for the wiring pieces.

[0013] Fourthly, the mounting plate can be quickly mounted on the wall surface through the mounting holes, which is convenient for personnel to install. Description of the Drawings

Detailed Embodiments

[0020] To better understand the present utility model, the content of the present utility model will be further clearly elaborated below in conjunction with the embodiments. However, the protection scope of the present utility model is not limited to the following embodiments only. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0021] As shown in Figure 1 , 2 , 3, and 4, a flexible and convenient wall-piercing terminal includes a mounting plate 101. Two sliding plates 103 corresponding to the upper and lower positions are slidably connected inside the mounting plate 101. Five docking cylinders 105 are arranged on the lower side of the upper sliding plate 103. Five fixed columns 104 are arranged on the upper side of the lower sliding plate 103. The five fixed columns 104 are respectively installed in cooperation with the adjacent five docking cylinders 105. Wiring pieces 106 are fixedly sleeved on the outer arc surfaces of the five fixed columns 104. A plurality of avoidance openings corresponding to the positions of the wiring pieces 106 are formed inside the mounting plate 101. A quick locking mechanism is arranged on the front side of the mounting plate 101. A protective frame plate 107 is arranged on the rear side of the mounting plate 101. All five wiring pieces 106 are located inside the protective frame plate 107.

[0022] As shown in Figure 1 , 2 , Figures 3 and 4, the quick locking mechanism includes two telescopic columns 205 corresponding to the left and right positions on the front side of the mounting plate 101. Rotating frames 201 are arranged on the telescopic ends of the two telescopic columns 205. Two connecting frames 206 are rotatably connected inside the two rotating frames 201. Rotating seats 204 are arranged on the left and right sides of the two sliding plates 103 respectively. The rear ends of the four connecting frames 206 are rotatably connected to the inside of the adjacent rotating seats 204 respectively. An elastic driving unit is arranged between the rotating frame 201 and the mounting plate 101. A linkage assembly is arranged between the two rotating frames 201. The elastic driving unit includes springs 203 arranged between the rotating frame 201 and the mounting plate 101. The two springs 203 are respectively sleeved on the outer arc surfaces of the corresponding telescopic columns 205. The linkage assembly includes a pressing plate 202 arranged between the two rotating frames 201. An anti-slip pad 207 is adhered to the front side surface of the pressing plate 202.

[0023] By pressing the pressing plate 202, the rotating frames 201 on both sides move backward, so that the connecting frames 206 on both sides inside them rotate and expand, thereby driving the fixing columns 104 and the docking cylinders 105 on the two sliding plates 103 to move away from each other. At this time, the springs 203 are in a compressed state. Then, the installation rings on the cable are inserted onto the fixing columns 104 by the personnel. Then, the pressing plate 202 is released. At this time, the springs 203 quickly rebound to drive the two sliding plates 103 to quickly approach each other. The cable is fixed by the fixing columns 104 sliding into the inside of the docking cylinders 105. During the process of pressing the pressing plate 202, the anti-slip pad 207 can effectively increase the friction between the human hand and the pressing plate 202, avoiding the phenomenon of hand slipping by the personnel. The wiring pieces 106 on the fixing columns 104 can be connected to external wires to facilitate the personnel to connect the conductive circuit. The frame plate can provide a protective shielding effect for the wiring pieces 106.

[0024] According to another embodiment of the present invention, as shown in Figure 1 , 2 , mounting holes 102 are opened at the four corners of the mounting plate 101. The mounting plate 101 can be quickly installed on the wall through the mounting holes 102.
