Description

Technical Field

[0001] The utility model relates to a connection structure of a power line in electromechanical equipment, in particular to a connection structure of a power line in a motor. Background Art

[0002] As we all know, high-power drive motors for electric motorcycles are widely used due to their advantages such as light weight, small size and high efficiency. Whether the drive motor can work properly directly affects the performance of the electric motorcycle itself. At present, the connection structure of the power cord in the drive motor is relatively complicated and cumbersome, and it is easy to scratch the power cord during assembly, which poses a safety hazard. In addition, since the wiring harness in the power cord cannot be fixed, the terminal is easily pulled and loosened during use, resulting in poor contact of the terminal and affecting the service life of the terminal. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a connection structure for the power line of a motor which is simple in structure, convenient in operation, safe and reliable.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a connection structure of the power cord in the motor, comprising: a shell and an insulating terminal block, the insulating terminal block comprising: a base plate, and a partition plate vertically arranged on the base plate, at least two terminal block fixing through holes are arranged on one side of the partition plate on the base plate, and terminal fixing installation holes corresponding to the terminals of the power cord are arranged on the other side of the partition plate, the shell is provided with terminal block fixing threaded holes corresponding to the terminal block fixing through holes one by one, and terminal fixing threaded holes corresponding to the terminal fixing installation holes one by one, a screw is selected to pass through the terminal block fixing through hole on the insulating terminal block and is arranged in the terminal block fixing threaded hole of the shell, and a screw is selected to pass through the terminal and is arranged in the terminal fixing installation hole on the insulating terminal block and the terminal fixing threaded hole of the shell.

[0005] As a preferred solution, in the connection structure of the power cord in the motor, the insulating terminal block is provided with columnar protrusions corresponding to the terminal fixing holes on the back side of its base plate, and the terminal fixing holes pass through the corresponding columnar protrusions.

[0006] As a preferred solution, in the connection structure of the power cord in the motor, the power cord is passed through the housing through a cable gland.

[0007] As a preferred solution, in the connection structure of the power cord in the motor, the cable gland is a plastic cable waterproof connector.

[0008] As a preferred solution, in the connection structure of the power cord in the motor, the cable gland is a nylon cable waterproof connector.

[0009] The beneficial effects of the present utility model are as follows:

[0010] 1. The structure of the insulating terminal block of the present utility model is very simple. During installation, it can be directly fixed with screws, which is very convenient to operate, and the connection of the terminals is also very reliable.

[0011] 2. By arranging a partition plate on the bottom plate of the present utility model, the screws for installing and fixing the terminal block are separated from the screws for installing the terminals, making the transfer of the terminals safer.

[0012] 3. By arranging columnar protrusions on the back of the bottom plate of the insulating terminal block of the present utility model, the screws for installing the terminals are completely immersed in the corresponding terminal fixing threaded holes in the shell, making the transfer of the terminals safer and more reliable.

[0013] 4. By passing the power cord through the gland and arranging it in the shell of the present utility model, the terminals will not be loosened due to pulling, thus ensuring good contact of the terminals and extending the service life of the terminals. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will describe in detail the specific implementation of the connection structure of the power cord in a motor according to the present utility model with reference to the drawings.

[0019] As Figure 1 shown, a connection structure of the power cord in a motor according to the present utility model includes: a shell 1 and an insulating terminal block 3, as Figure 2 and Figure 3As shown in the figure, the insulating terminal block 3 includes: a bottom plate 30 and a partition plate 31 vertically arranged on the bottom plate 30. On one side of the partition plate 31 on the bottom plate 30, there are two terminal block fixing through holes 301, and on the back of the other side of the partition plate 31, there are three columnar protrusions 32. The bottom plate 30 is respectively provided with terminal fixing and mounting holes 302 penetrating through the corresponding columnar protrusions 32 opposite to each columnar protrusion 32 on the other side of the partition plate 31. The terminal fixing and mounting holes 302 correspond to the terminals 51 of the power line 5. On the housing 1, there are terminal block fixing threaded holes corresponding one by one to the terminal block fixing through holes 301, and terminal fixing threaded holes corresponding one by one to the terminal fixing and mounting holes 302 (which belongs to the conventional technology in the field and will not be further described here). Select a fixing screw 2 to pass through the terminal block fixing through hole 301 on the insulating terminal block 3 and be arranged in the terminal block fixing threaded hole of the housing 1. Select a connection screw 4 to pass through the terminal 51 of the power line 5 and be arranged in the terminal fixing and mounting hole 302 on the insulating terminal block 3 and the terminal fixing threaded hole of the housing 1.
