Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motors, in particular to a motor coil bracket with a male connector. Background Art
[0002] In modern motor design and manufacturing, achieving effective connection between the motor's internal coils and external circuits is one of the key links to ensure motor performance. The traditional motor manufacturing process usually includes the following steps:
[0003] 1. Solder the printed circuit board (PCB) to the male connector to form an intermediate transition assembly.
[0004] 2. Install the male connector with PCB onto the coil holder.
[0005] 3. Solder the wires on the coil bracket to the PCB board to establish an electrical path.
[0006] 4. The final step is to fix the PCB, male connector and coil holder into one piece through the injection molding process to ensure mechanical stability and electrical continuity between them.
[0007] However, this traditional method has numerous drawbacks. First, the production process is complex and time-consuming due to the assembly of multiple independent components. Second, defects can easily be introduced during the multiple welding and injection molding processes, compromising product quality. Finally, high material costs and cumbersome manual labor contribute to the high overall manufacturing cost of the final product.
[0008] As market demand for higher performance and lower prices continues to grow, simplifying motor manufacturing processes and reducing unnecessary steps has become a pressing issue for the industry. Therefore, developing new technology solutions that can both meet functional requirements and significantly reduce production costs has become increasingly important.
[0009] In view of the above background, the present invention provides a motor coil support with a male connector. Utility Model Content
[0010] In view of the deficiencies in the background technology, the utility model provides a motor coil bracket with a male connector.
[0011] The technical solution adopted by the present utility model is: a motor coil bracket with a male connector, including a coil bracket, a male connector integrally formed on the coil bracket, a connection port for docking with a female connector is provided on one side of the male connector, a plurality of pins are connected to the bottom wall of the connection port, one end of the pin is located on one side of the connection port, and a wire groove is provided on the other end pin located on one side of the coil bracket.
[0012] Furthermore, the wire trough is a "U"-shaped structure.
[0013] Furthermore, a puncture structure for puncturing the outer sheath of the wire is provided in the wire groove.
[0014] Furthermore, the coil support is an equilateral polygonal structure of an equilateral hexagon or an equilateral octagon, and the male connector is integrally formed on one of the side walls of the coil support.
[0015] Furthermore, a socket for connecting a pin is provided on the bottom wall of the connecting port, and a separation step is provided between the sockets.
[0016] The beneficial effects of the utility model are:
[0017] 1. Simplified production process: Because the male connector and coil bracket are integrated into a single design, with pins on the integrated male connector connecting to the copper wires on the coil bracket, there is no need for additional soldering or assembly steps to secure the male connector to the coil bracket, nor is a separate PCB board required as an electrical connector. This greatly simplifies the entire motor assembly process.
[0018] 2. Reduced costs: Eliminating the PCB and related processes such as soldering and injection molding reduces raw material consumption and labor costs. In addition, a simpler structure means the use of more economical production equipment and technology, further reducing overall production costs.
[0019] 3. Improved reliability: This solution effectively avoids the quality issues that can arise from multiple soldering steps in traditional methods. The integrated design reduces the number of joints and enhances the mechanical strength between components, contributing to improved durability and stability of the final product.
[0020] 4. Enhanced Flexibility: This solution allows for customization of male connector-coil bracket assemblies in various sizes and shapes, according to specific customer needs, providing greater freedom in motor design. Furthermore, the wire guide design on the pins facilitates quick and accurate connection of the copper wires on the coil bracket.
[0021] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] The utility model provides a motor coil bracket with a male connector.
[0028] In this embodiment, referring to Figure 1-3 The motor coil bracket with a male connector includes a coil bracket 1, on which a male connector 2 is integrally formed. One side of the male connector 2 is provided with a connection port 3 for docking with a female connector. A plurality of pins 4 are connected to the bottom wall of the connection port 3. One end of the pin 4 is located on one side of the connection port, and a wire groove 5 is provided on the pin at the other end located on one side of the coil bracket.
[0029] In this technical solution, by integrating the male connector directly into the coil support, the assembly steps during motor manufacturing are simplified (see the table below), reducing production costs. This integrated design not only enhances the mechanical strength between components but also improves the reliability of the electrical connection. Furthermore, the wire grooves on the pins facilitate installation and securing with the copper wires on the coil support, ensuring good electrical contact.

Required Materials Male connector, PCB board, injection molding material, coil bracket Coil holder with male connector
[0032] Specifically, the wire duct 5 is a "U"-shaped structure.
[0033] In this embodiment, the "U"-shaped wire trough design allows the wires to be more stably positioned within the trough, preventing them from shifting or becoming loose, thereby ensuring a stable electrical connection over long-term use. Furthermore, the "U"-shaped structure facilitates quick and accurate wiring, improving assembly efficiency.
[0034] Specifically, a puncture structure for puncturing the outer sheath of the wire is provided in the wire groove.
[0035] In this embodiment, the piercing structure can directly penetrate the wire insulation layer to achieve direct electrical contact with the conductor without stripping the wire insulation. This not only simplifies the wiring process and reduces manual operation time, but also avoids wire damage that may be caused by manual stripping, further improving the safety and reliability of the electrical connection.
[0036] The puncture structure belongs to conventional technology in the prior art. The following are examples of common puncture mechanisms:
[0037] 1. Needle-puncture contacts:
[0038] This piercing structure typically consists of one or more sharp metal pins. When a wire is inserted, these pins pierce the wire's insulation and make good electrical contact with the conductor inside. Needle-piercing contacts can be single pins or multi-pin arrays, suitable for different wire diameters and types.
[0039] 2. Fork-shaped puncture contacts:
[0040] The forked piercing contact resembles two sharp, V-shaped blades facing each other. When a wire is pressed between the blades, they cut through the insulation and clamp the inner conductor. This design provides a larger contact area, helping to improve the stability and reliability of the electrical connection.
[0041] 3. Sawtooth puncture contacts:
[0042] The serrated contact has multiple small teeth that simultaneously pierce the insulation and grip the conductor when the wire is pressed between them. This design is particularly suitable for applications that require a certain amount of tension as it provides a better mechanical fixation.
[0043] Specifically, the coil support is an equilateral polygonal structure of an equilateral hexagon or an equilateral octagon, and the male connector is integrally formed on one of the side walls of the coil support.
[0044] In this embodiment, an equilateral polygonal coil support (e.g., a hexagon or octagon) provides a more uniform magnetic field distribution and improved heat dissipation. The male connector is located on one side of the coil support, which can better adapt to different installation space requirements and help optimize the compactness and aesthetics of the entire motor structure.
[0045] Specifically, a socket 9 for connecting the plug pin 4 is provided on the bottom wall of the connection port, and a separation step 10 is provided between the sockets.
[0046] In this embodiment, the sockets are used to precisely install the pins, while the separating steps ensure sufficient spacing between the pins to prevent short circuits. This sophisticated layout helps improve the quality of the electrical connection and also facilitates the inspection or replacement of individual pins during subsequent maintenance.
[0047] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
