However, in some high-vibration working environments, the solder joints on the terminals often become loose or fall off due to vibration, which can affect the normal operation of the micro motor and pose certain safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide a motor housing that is not easily detached, thus solving the problem that the solder joints on the terminals of micro motors often become loose or fall off due to vibration during use.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A motor housing that is not easily detached includes a housing body. A trapezoidal support block is fixedly connected to the bottom of the housing body. A terminal block is fixedly connected to the bottom of the trapezoidal support block. Copper sheets are fixedly connected to both the front and rear sides of the terminal block. A first U-shaped plate is attached to both the front and rear sides of the trapezoidal support block. A first rubber block is adhered to the inner wall of the first U-shaped plate. A strip hole is opened on both the front and rear sides of the first U-shaped plate. A cylinder is fixedly connected to both the front and rear sides of the trapezoidal support block.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] like Figures 1 to 8As shown, the motor housing, which is not easily detached, includes a housing body 1. A trapezoidal support block 2 is fixedly connected to the bottom of the housing body 1. A terminal block 3 is fixedly connected to the bottom of the trapezoidal support block 2. Copper sheets 4 are fixedly connected to both the front and rear sides of the terminal block 3. A first U-shaped plate 5 is fitted to both the front and rear sides of the trapezoidal support block 2. A first rubber block 6 is adhered to the inner wall of the first U-shaped plate 5. Strip holes 7 are opened on both the front and rear sides of the first U-shaped plate 5. A cylinder 8 is fixedly connected to both the front and rear sides of the trapezoidal support block 2. The surface of the cylinder 8 is in contact with the inner wall of the strip hole 7. The front and rear sides of the trapezoidal support block 2 are provided with strip grooves 9. The front and rear sides of the trapezoidal support block 2, the inner wall of the strip grooves 9 and the bottom of the first U-shaped plate 5 are all provided with limit brackets 10. The inner wall of the limit brackets 10 and the left side of the trapezoidal support block 2 are fixedly connected with springs 11. The inside of the trapezoidal support block 2 is provided with a first wiring hole 12. The bottom of the main body 1 of the casing is provided with a second wiring hole 13. The first wiring hole 12 and the second wiring hole 13 are aligned.
[0029] The limiting bracket 10 includes a second U-shaped plate 101, a sliding column 102, a limiting plate 103, and a hollow block 104. The front and rear sides of the trapezoidal support block 2 are both in contact with the inner wall of the second U-shaped plate 101. The front and rear sides of the inner wall of the second U-shaped plate 101 are both fixedly connected to the surface of the sliding column 102. The surface of the sliding column 102 is in contact with the inner wall of the strip groove 9. The bottom of the second U-shaped plate 101 is fixedly connected to the upper surface of the limiting plate 103. The upper surface of the limiting plate 103 is in contact with the bottom of the first U-shaped plate 5. The bottom of the hollow block 104 is fixedly connected to the inner wall of the second U-shaped plate 101. The inner wall of the hollow block 104 is fixedly connected to the surface of the spring 11. The tension of the spring 11 on the hollow block 104 is greater than the weight of the limiting bracket 10.
[0030] It should be noted that the wires on the terminal block 3 enter the housing body 1 from the first wiring hole 12 and the second wiring hole 13, and are connected to the wires inside the housing body 1. Through the cooperation of the cylinder 8 and the strip hole 7, the first U-shaped plate 5 can not only move up and down, but also rotate around the cylinder 8.
[0031] Through the cooperation of the sliding column 102 and the strip groove 9, the second U-shaped plate 101 can only move left and right. When the limiting plate 103 on the limiting bracket 10 contacts the first U-shaped plate 5, the tension of the spring 11 on the limiting bracket 10 prevents the limiting plate 103 from automatically separating from the first U-shaped plate 5. The limiting plate 103 fixes the first rubber block 6 to the terminal 3. At this time, the first rubber block 6 presses the solder joint on the copper sheet 4, and the pressing pressure makes it difficult for the wire soldered on the copper sheet 4 to loosen or fall off.
[0032] like Figures 1 to 7As shown, the bottom of the trapezoidal support block 2 is provided with a trapezoidal groove 14, which is located on the left side of the first U-shaped plate 5. When the first U-shaped plate 5 rotates into the trapezoidal groove 14, the cooperation between the first U-shaped plate 5 and the trapezoidal groove 14 prevents the limiting plate 103 on the limiting bracket 10 from moving below the terminal 3. This allows the user to directly fix the limiting plate 103 on the left side of the terminal 3 when soldering the wire to the copper sheet 4, and prevents the limiting plate 103 from affecting the soldering process.
[0033] like Figures 1 to 9 As shown, a hollow cylinder 15 is fixedly connected to the bottom of the trapezoidal support block 2. The hollow cylinder 15 is located to the right of the terminal block 3. A groove 16 is provided at the bottom of the hollow cylinder 15. An arc plate 17 is fixedly connected to the inner wall of the groove 16. A second rubber block 18 is attached to the inner wall of the hollow cylinder 15. The bottom of the second rubber block 18 is bonded to the inner wall of the first U-shaped plate 5.
[0034] It should be noted that after the first rubber block 6 is fixed below the terminal block 3, the second rubber block 18 can be fixed inside the hollow cylinder 15 through the first U-shaped plate 5, and the second rubber block 18 presses the wire inside the arc plate 17. At this time, the pressing force makes the solder joint not subject to tension after the wire is pulled, thereby further making the copper sheet 4 and the wire more firmly fixed.
[0035] During assembly, the following steps are taken: First, the limiting bracket 10 is moved to the left to separate the limiting plate 103 from the first U-shaped plate 5. Then, the second rubber block 18 is moved out of the hollow cylinder 15 by pulling the first U-shaped plate 5, and the first U-shaped plate 5 is rotated into the trapezoidal groove 14. At this time, through the cooperation of the first U-shaped plate 5 and the trapezoidal groove 14, the limiting plate 103 on the limiting bracket 10 cannot move below the terminal 3. Then, the wire is soldered onto the copper sheet 4 and placed in the arc plate 17.
[0036] After the wire welding is completed, the second rubber block 18 is inserted into the hollow cylinder 15 by rotating and moving the first U-shaped plate 5. The tension of the spring 11 on the hollow block 104 causes the limiting plate 103 to fit against the bottom of the first U-shaped plate 5. At this time, the limiting plate 103 fixes the first rubber block 6 at the terminal 3 and presses the solder joint on the copper sheet 4. Then, the pressing pressure makes it difficult for the wire welded to the copper sheet 4 to loosen or fall off. At the same time, the second rubber block 18 presses the wire in the arc plate 17 and the pressing pressure makes the solder joint not subject to tension after the wire is pulled.
[0037] When it is necessary to separate the wire from the copper sheet 4, first move the limiting bracket 10 to the left to separate the limiting plate 103 from the first U-shaped plate 5. Then, by pulling the first U-shaped plate 5, the second rubber block 18 is moved out of the hollow cylinder 15, and the first U-shaped plate 5 is rotated into the trapezoidal groove 14. At this time, through the cooperation of the first U-shaped plate 5 and the trapezoidal groove 14, the limiting plate 103 on the limiting bracket 10 can not move to the bottom of the terminal 3, and the solder joints on the copper sheet 4 are exposed.
[0038] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
