Description

Technical Field

[0001] The utility model relates to the field of motor wiring, mainly to a motor lead-out wire wiring structure. Background Art

[0002] Terminal blocks, as a circuit connection method, are widely used in the electrical field. Their origins can be traced back to the early development of power systems. During the early stages of power system construction, people recognized the need for reliable, safe, and easy-to-maintain circuit connection methods. The traditional method of connecting insulated and bare wire ends posed safety risks and maintenance difficulties, leading to the emergence of terminal blocks. The primary purpose of terminal blocks is to provide a centralized, reliable connection point for conveniently connecting and disconnecting wires. Connecting at the terminal block simplifies circuit wiring and maintenance, improving circuit reliability and maintainability. With the continuous development of power systems and the increase in electrical equipment, terminal block connections have been continuously optimized and improved, evolving from simple terminal blocks to modern, multifunctional ones. Terminal blocks are widely used in power distribution systems, control systems, automation equipment, and instrumentation. They are used not only in low-voltage circuits but also in medium- and high-voltage power systems, making them a common connection method in electrical engineering design and installation. However, current terminal blocks suffer from issues such as insufficient wiring flexibility and convenience, interference between currents, and unsuitability for applications with limited mechanical dimensions. Utility Model Content

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a motor lead wire wiring structure, the main technical problem to be solved is how to increase the flexibility and convenience of wiring and reduce the interference between currents during the motor wiring process.

[0004] The purpose of the utility model is achieved through the following technical solutions: A motor lead-out wiring structure, comprising a wiring base plate and a wiring copper bar, wherein the wiring base plate is provided with three bosses at intervals, the bosses comprising boss A, boss B and boss C, each of the bosses being provided with two fixing holes A, and a positioning column being provided between the two fixing holes A; the wiring copper bar is in an L-shaped structure, comprising wiring copper bar A, wiring copper bar B and wiring copper bar C, one side of the wiring copper bar being positioned and connected to the boss, and the other side of the wiring copper bar being provided with a group of wiring holes, one wiring hole of the wiring copper bar A, the wiring copper bar B and the wiring copper bar C being respectively connected to one of the three phases of the motor coil power line and being fixed by a wiring bolt, and the other wiring holes of the wiring copper bar A, the wiring copper bar B and the wiring copper bar C being electrically connected to the wiring cabinet through an outlet connector.

[0005] Furthermore, the wiring copper bus B and the wiring copper bus C are symmetrically arranged facing each other, and the wiring copper bus B and the wiring copper bus A are arranged in the same direction.

[0006] Furthermore, a positioning hole matching the positioning column and a fixing hole B matching the fixing hole A are provided on one side surface of the wiring copper busbar. The wiring copper busbar is positioned and fixed to the boss through fixing bolts, fixing hole A and fixing hole B.

[0007] Furthermore, the wiring base plate is fixedly connected to the side wall of the junction box relative to the side cover of the junction box through the mounting hole.

[0008] The beneficial effects of the utility model are:

[0009] 1. Use the wiring base plate and the wiring copper busbar for wiring. The connection of each wiring copper busbar is independent, which makes it very convenient to modify and maintain the circuit, so it has good flexibility.

[0010] 2. Using a wiring base plate and wiring busbars for wiring is advantageous when space is limited and cables are routed sideways. Different busbars connect to different wires (each busbar connects to one of the three phases), making it easier to identify and find specific circuits. This is especially important in complex circuit wiring and troubleshooting.

[0011] 3. Use a wiring base plate and wiring copper busbars for wiring. Each wiring copper busbar is separated by a certain distance and is an independent contact point. The distance between the lead wires is separated to reduce interference, so that the current is isolated between different terminal posts, which helps to reduce problems caused by current interference and feedback.

[0012] 4. Compared to common terminal blocks, the use of copper bars B and C is symmetrically arranged, with copper bars B and A facing the same direction. This structure can reduce the length of the terminal base while maintaining the spacing. Using this type of terminal block wiring usually only occupies a narrow space, which is particularly suitable for applications where mechanical dimensions are limited.

A threaded seat that cooperates with the fixing bolt 6 can be pre-embedded in the wiring base plate 1.

[0026] like Figure 1 、 4 As shown, the wiring base plate 1 is fixedly connected to the side wall of the wiring box 9 relative to the wiring box side cover 9-1 through the mounting hole 1-1.

[0027] like Figure 5-8 The installation and use diagram shown includes a motor base 7, a motor outlet 8, a junction box 9, a junction box side cover 9-1, a junction box top cover 9-2, an outlet connector 10, and a junction box base 11. The installation includes the following steps:

[0028] 1. First, mate the junction box base 11 with the motor outlet 8;

[0029] 2. Install the junction box 9 on the corresponding position of the junction box base 11;

[0030] 3. Install the assembled copper busbar and wiring base into the junction box 9;

[0031] 4. Connect the motor lead wires;

[0032] 5. Replace the junction box cover 9-2 and tighten it with screws.

[0033] Note: The copper busbar and the motor lead wire should have good contact to ensure that there will be no adverse effects caused by poor wiring;

[0034] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
