Description

Technical Field

[0001] This utility model relates to the field of terminal block shorting technology, and specifically to a terminal block shorting device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In electrical construction, there are various wiring methods for terminal blocks. In many cases, it's necessary to short-circuit the terminals on the terminal block. Traditionally, this involves using existing cables to create short-circuit connections, which requires adding an extra cable (with cable terminations at both ends) to achieve the desired short-circuit. This is time-consuming and labor-intensive, and often results in the need to crimp two cable ends to the terminals on the terminal block simultaneously. This can lead to problems such as insecure crimping, loose connections, short-circuit cables that are too long and unsightly, and limited installation space that cannot accommodate many terminals. Furthermore, this is especially problematic with direct-insertion terminal blocks. Utility Model Content

[0004] The purpose of this utility model is to provide a terminal block shorting device to solve the problems of time-consuming and labor-intensive shorting wire production, large differences in shorting wire production quality, and the inability to produce reliable shorting wires for direct-insertion terminals during the terminal block shorting process.

[0005] A terminal block shorting device includes a tubular crimp terminal, a first pin-type parallel crimp terminal, and the tubular crimp terminal and the first pin-type parallel crimp terminal are connected by an adaptive metal connector;

[0006] The tubular crimping terminal includes a tubular crimping part and a second pin-type parallel crimping terminal. The tubular crimping part is used to insert the assembly cable. The first pin-type parallel crimping terminal and the second pin-type parallel crimping terminal are plugged into the terminal block.

[0007] As a further technical solution, the tubular crimping portion of the tubular crimping terminal is made of copper.

[0008] As a further technical solution, the second pin-type parallel crimp terminal of the tubular crimp terminal is made of copper.

[0009] As a further technical solution, the first pin-type parallel crimp terminal is made of copper.

[0010] As a further technical solution, the second pin-type parallel crimp terminal is also made of copper.

[0011] As a further technical solution, a wire insertion port is provided at the top of the tubular wire pressing part.

[0012] As a further technical solution, the tubular crimping part and the second pin-type parallel crimping terminal are connected by a metal transition part.

[0013] As a further technical solution, the metal transition section is made of copper.

[0014] As a further technical solution, the adaptive metal connector is made of copper.

[0015] As a further technical solution, the two ends of the adaptive metal connector are respectively welded to the top of the tubular crimping part and the first pin-type parallel crimping terminal.

[0016] The beneficial effects of one or more of the above technical solutions:

[0017] (1) The tubular crimping part of the tubular crimping terminal is used to crimp the cable. The first pin type parallel crimping terminal and the second pin type parallel crimping terminal are used to plug into the terminal block. Only one cable needs to be crimped to achieve short connection of the terminal block.

[0018] (2) The tubular crimp terminal and the first pin type parallel crimp terminal are connected by a connecting piece with an adaptive length. It can be installed adaptively according to the required distance between the shorting terminals, avoiding the use of more types of shorting wires and reducing construction costs. It can also effectively avoid problems such as loose connections in the terminal block and inconsistent wiring quality caused by differences in the skill level of the construction personnel.

[0019] (3) By adopting tubular crimp terminals, pin-type parallel crimp terminals, and adaptive metal connection technology, the problem that the direct-insertion terminal block cannot achieve terminal block short-circuiting is solved. Attached Figure Description

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-3 This section describes the specific implementation method of this embodiment.

[0026] This application provides a terminal block shorting device, referring to... Figure 1 A terminal block shorting device includes a tubular crimp terminal, a first pin-type parallel crimp terminal 8, and the tubular crimp terminal and the first pin-type parallel crimp terminal 8 are connected by an adaptive metal connector 7.

[0027] The tubular crimp terminal includes a tubular crimping part 5, a second pin-type parallel crimping terminal 3, and a metal transition part 4. Both the tubular crimping part 5 and the second pin-type parallel crimping terminal 3 are made of copper to ensure good conductivity of the cable. The tubular crimping part 5 and the second pin-type parallel crimping terminal 3 are connected by the metal transition part 4. This metal transition part 4 ensures a secure connection between the assembled cable and the tubular crimping part 5 and the second pin-type parallel crimping terminal 3, reducing the risk of loose connections during short-circuit installation.

[0028] The top of the tubular wire clamping part 5 is provided with a wire clamping insertion port 6 for inserting the assembly cable 1. Before inserting the assembly cable 1, it is necessary to strip about 2 mm of the short-circuited assembly cable 1, pass the exposed copper wire through the tubular wire clamping part 5, and clamp the inserted assembly cable 1 through the wire clamping insertion port 6.

[0029] The first pin-type parallel crimp terminal 8 is made of copper and is connected to the tubular crimp terminal via an adaptive metal connector 7. The two ends of the adaptive metal connector 7 are respectively connected above the tubular crimp section 5 and the first pin-type parallel crimp terminal 8. The adaptive metal connector 7 can be adaptively selected for installation according to the required distance between the shorting terminals (adaptive length 1mm-20mm), avoiding the use of more models of this type of product and reducing construction costs. Furthermore, the terminal block shorting device can be designed in different sizes according to site requirements, allowing the adaptive length of the adaptive metal connector 7 to be between 1mm and 100mm.

[0030] During the short-circuiting process, firstly, the second pin-type parallel crimping end 3 of the tubular crimping terminal of the assembly cable 1 is crimped into the terminal block's wiring terminal. Then, the first pin-type parallel crimping end 8 is crimped into the wiring terminal of the terminal block to be short-circuited. By using the tubular crimping part 5 of the tubular crimping terminal to crimp the cable and the asymmetrical process of connecting the wiring terminal in parallel with the pin-type parallel crimping end, only one cable needs to be crimped to achieve short-circuiting of the wiring terminals.

[0031] The working principle of the terminal block shorting device provided in this embodiment is as follows:

[0032] The cable 1 is assembled by pressing the tubular crimping part 5 of the tubular crimping terminal. The second pin-type parallel crimping end 3 of the tubular crimping terminal is then inserted into the terminal block on the terminal block. Depending on the position of the terminal block to be shorted, the length of the adaptive metal connector 7 is adjusted to ensure a suitable distance between the second pin-type parallel crimping end 3 and the first pin-type parallel crimping end 8. Then, the first pin-type parallel crimping end 8 is inserted into the terminal block to be shorted, thus achieving shorting between the terminal blocks. Using this shorting device effectively avoids problems such as inconsistent wiring quality due to differences in the skill level of construction personnel, loose connections in the terminal blocks, and the inability of direct-insertion terminal blocks to achieve shorting.

[0033] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
