Description

Technical Field

[0001] This utility model relates to the field of terminal crimping technology, and in particular to a motor terminal crimping device. Background Technology

[0002] Motor terminals are electrical connection components between motor windings and external conductors. They are typically made of conductive metal (copper / copper alloy) and include structures such as threaded posts, terminal holes, or solder surfaces. They must possess high conductivity, mechanical strength, and corrosion resistance. Their core function is to reliably transmit operating current, while also meeting the requirements for insulation protection (such as plastic bases) and rapid installation. They are widely used in cable termination connections for various AC / DC motors, servo motors, and other electrical equipment.

[0003] Existing motor terminals are generally installed inside the motor's junction box. When wiring, the worker opens the box cover, connects the wires to the terminals, and then closes the junction box cover.

[0004] Based on the aforementioned technologies, the applicant believes that existing junction boxes lack a crimping device between the connecting post and the connecting wire during installation. The simple winding or bolt installation method has poor stability and is prone to loosening during actual use. In response to the above problems, we have introduced a motor terminal crimping device.

[0015] In a preferred embodiment, the main material of the pressure plate is silicon nitride ceramic with high insulation properties.

[0016] The crimping plate is made of silicon nitride ceramic material, which has excellent insulation properties and high temperature resistance, preventing current leakage and short circuit risks, while also having high mechanical strength to ensure a stable and reliable crimping process.

[0017] In a preferred embodiment, a support base is fixedly connected to the bottom of the motor body, and mounting holes are symmetrically opened on both sides of the interior of the support base.

[0018] The support base securely fixes the motor body through the mounting holes, reducing vibration and displacement during operation, improving the overall stability of the equipment, and is suitable for different installation environments, such as industrial motors or automated equipment.

[0019] The motor terminal crimping device provided by this utility model has the following advantages:

[0020] Firstly, the wiring mechanism allows for crimping between the terminals of the wiring box. The device has a reasonable structure, reliable crimping, and ensures a firm connection, making it suitable for various motor wiring needs.

The wiring mechanism includes a crimping component and a mounting component, which cooperate with each other. The crimping component includes a pressing cover 3, which is positioned above the junction box 2. Terminals 4 are fixedly connected at equal intervals inside the junction box 2.

The mounting component includes a mounting groove 8, which is triangularly formed and located on the top of the pressing cover 3. A bolt 9 is threadedly connected inside the mounting groove 8, and the bolt 9 is threadedly connected to the junction box 2.

[0031] In this embodiment: the wire is introduced into the junction box 2 through the wiring hole 10 and inserted into the corresponding terminal 4. The pressing cover 3 is closed, so that the clearance hole 6 of the crimping plate 5 is aligned with the terminal 4.

[0032] In the above technical solution, considering that the existing junction box installation lacks a crimping device between the connecting post and the connecting wire, and the simple winding or bolt 9 installation method has poor stability and is prone to loosening in actual use, the specific operation is as follows to solve this problem:

The terminal block 4 is made of copper-tungsten alloy material, which has both high conductivity and high temperature resistance, can withstand large current load, reduce resistance heating, and extend service life. It is suitable for high-power motor application scenarios. The pressing plate 5 is made of silicon nitride ceramic material, which has excellent insulation performance and high temperature resistance, prevents current leakage and short circuit risk, and has high mechanical strength to ensure stable and reliable pressing process.

The pressing cover 3 is closed, and the clearance hole 6 of the crimping plate 5 is aligned with the terminal 4. After pressing down, the wire and the terminal 4 are tightly crimped through the rectangular connecting groove 7. The bolt 9 is used to lock the pressing cover 3 to ensure a firm crimp. The heat dissipation hole 12 promotes heat dissipation. The copper-tungsten alloy terminal 4 and the silicon nitride ceramic crimping plate 5 work together to ensure high conductivity and insulation safety. The support base 13 maintains the stable operation of the equipment. The equipment has a reasonable structure and reliable crimping, and is suitable for various motor wiring needs.
