[0002] Existing electronic speed controllers typically connect the circuit board to one side of the motor. Both the positive and negative terminals of the circuit board use stamped male connectors, with one or two terminals soldered together. Because these stamped male connectors are thin, have a small contact area, and insufficient strength, they are prone to deformation or breakage, thus affecting the connection between the speed controller and the motor. Therefore, a high-strength CNC-machined positive and negative male connector and speed controller mounting structure were designed to improve the connection structure of the speed controller and ensure its operational stability. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 4 This utility model provides a technical solution: a high-strength CNC positive and negative male connector insert, including an integrally formed connecting part 41 and a positioning part 43. The lower end of the positioning part 43 is inserted into the circuit board 3 and then welded and fixed. The upper end of the connecting part 41 is connected to the speed controller. A limiting part 42 is formed on the upper end of the positioning part 43. The size of the limiting part 42 is larger than the size of the positioning part 43. The lower end of the limiting part 42 is attached to the upper end of the circuit board 3 to position the insertion depth of the positioning part 43 and also prevent the connecting part 41 from being inserted into the lower end of the circuit board 3, thereby reducing the contact between the connecting part 41 and the speed controller. The contact area between the components is reduced. The connecting part 41 is flat and strip-shaped. The existing stamped terminal female is an arc-shaped piece. The arc-shaped piece has a small thickness and low strength, and is prone to deformation or breakage. Moreover, the contact area of ​​the arc-shaped piece is small. Only the outer arc-shaped surface is electrically connected. The electrical connection area is small. At the same time, stamping is required, which involves many processes and high production costs. Therefore, the connecting part 41 is designed as a flat and strip-shaped piece. This strengthens the male plug 4, increases the contact area of ​​the electrical connection, improves the current carrying capacity, and the one-piece molding reduces the production process and lowers the production cost.

[0022] The top of the connecting part 41 is chamfered, which guides the connection between the connecting part 41 and the speed controller.

[0023] The positioning part 43 is cylindrical, semi-circular, or polygonal. The through hole on the circuit board 3 matches the shape of the positioning part 43. The positioning part 43 is inserted into the circuit board 3. The semi-circular or polygonal positioning part 43 fixes the positioning part 43 to the circuit board 3, preventing the positioning part 43 from rotating. The different shapes of the positioning part 43 increase the contact surface, improve the connection strength, and also improve the positioning accuracy during production, making the consistency of the product more stable.

[0024] A threaded hole is provided on the side of the positioning part 43. The screw passes through the side of the circuit board 3 and is connected in the threaded hole to fix the positioning part 43, so that the positioning part 43 will not move up and down, thus enhancing the connection stability between the positioning part 43 and the circuit board 3.

[0025] A reinforcing part 44 is formed between the limiting part 42 and the connecting part 41, which enhances the connection strength and rigidity between the connecting part 41 and the limiting part 42.

[0026] like Figures 1 to 3 As shown, this utility model also provides a technical solution: a speed controller mounting structure, including a motor 2, a circuit board 3, and a top cover 1. The circuit board 3 has insert holes 31, which are symmetrically distributed in the center to prevent incorrect installation of the speed controller and prevent incorrect installation direction. The insert holes 31 are connected to and welded with the aforementioned high-strength CNC positive and negative male connectors 4. The outer edge of the top cover 1 has centrally symmetrically arranged through holes. The upper end of the male connector 4 is inserted into the through hole, and the upper end of the male connector 4 is located above the top cover 1 to facilitate the connection between the male connector 4 and the speed controller. The circuit board 3 also has pin holes 32, in which pins are inserted. The lower end of the pin is connected to the motor 2, and the upper end of the pin is connected to the speed controller to transmit signals to the speed controller and realize the connection with the speed controller.

[0027] like Figure 2 and 3 As shown, a positioning post 5 is installed on the upper end of the motor 2, and a positioning hole 33 corresponding to the positioning post 5 is opened on the circuit board 3. The positioning post 5 is inserted into the positioning hole 33 to position and install the circuit board 3, further ensuring that the surface of the circuit board 3 is aligned with the surface of the motor 2, so that the overall side of the device is flush and the aesthetics are guaranteed.

[0028] The circuit board 3 has multiple round holes 34 on its edge. The motor 2 has threaded holes at the corresponding positions of the round holes 34. The upper cover 1 has bolts inserted into it, and the lower end of the bolts is connected to the threaded holes of the motor 2 to fix the circuit board 3 to the motor 2.

[0029] The upper surface of the cover 1 has a groove formed in the center, and a positioning platform 6 is inserted into the groove. The upper end of the positioning platform 6 is located on the upper end of the cover 1. The positioning platform 6 is used for the installation and positioning of the electronic speed controller.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
