[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0040] The following is for reference. Figures 1-7 A connector 100 according to a first aspect embodiment of the present invention is described.

[0041] like Figure 1 As shown, the connector 100 according to the first aspect of the present invention includes: a housing 1, a terminal 2, and a resistor 3.

[0042] Specifically, the housing 1 has a receiving cavity 12 and a terminal slot 121 communicating with the receiving cavity 12. The terminal 2 is adapted to pass through the receiving cavity 12 and extend into the terminal slot 121. The resistor 3 is located in the receiving cavity 12, and its two ends are connected to the terminal 2. In other words, by integrating the resistor 3 into the connector 100, the structure of the existing motor connector 100 is simplified, and the number of components and process complexity are reduced. The housing 1 has a receiving cavity 12 and a terminal slot 121. The receiving cavity 12 is used to place the resistor 3, and the terminal slot 121 is used to insert the terminal 2. The terminal 2 passes through the receiving cavity 12 and extends into the terminal slot 121, ensuring electrical connection while also providing mechanical fixation. The resistor 3 is located in the receiving cavity 12, and its two ends are connected to the corresponding terminal 2 to realize the resistive function.

[0043] Understandably, by directly integrating the resistor 3 inside the connector 100, steps such as external soldering and heat shrink tubing protection are reduced, greatly simplifying the assembly process. Furthermore, the elimination of additional components such as insulated wires, heat shrink tubing, and cable ties reduces the overall production cost of the connector 100. The integrated design reduces the number of connection points, thereby reducing the risk of poor contact, avoiding the influence of the external environment on the resistor 3, improving the reliability of the connector 100, and making the overall structure more compact and space-saving.

[0044] In the prior art, the motor connector 100 is connected to a resistor, with the leads at both ends of the resistor welded to the cores of an insulated wire. Heat-shrink tubing is added to the welded joints of the resistor and its leads 31 for protection. The other end of the insulated wire is crimped to the terminals 2 of the connector 100. One side of the terminal 2 is inserted into the connector 100. An insulating sleeve is added outside the insulated wire and heat-shrink tubing, and a cable tie is added outside the insulating sleeve for fixation. This existing solution involves many materials, complex processes, and high costs. According to the present invention, the connector 100 integrates the resistor 3 inside the connector 100, eliminating the need for additional insulated wires, heat-shrink tubing, and cable ties. This reduces the overall production cost of the connector 100. The integrated design reduces the number of connection points, thereby reducing the risk of poor contact, avoiding the influence of the external environment on the resistor 3, improving the reliability of the connector 100, and reducing external welding and heat-shrink tubing protection steps, greatly simplifying the assembly process.

[0045] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 5 As shown, a positioning groove 131 is formed within the receiving cavity 12, and the positioning groove 131 is along a first direction (e.g., Figure 1Extending in the first direction (as shown), the resistor 3 is located within the positioning groove 131. That is, by forming the positioning groove 131 within the receiving cavity and positioning the resistor 3 within it, the installation stability of the resistor 3 and the reliability of the overall structure are significantly improved. It can be understood that by forming the positioning groove 131, the precise position of the resistor 3 within the receiving cavity 12 is ensured, preventing the resistor 3 from moving or being damaged due to vibration or other external forces. Furthermore, the positioning groove 131 simplifies the assembly process of the resistor 3, reducing the number of manual adjustment steps required. The first direction is consistent with the electrical connection direction of the resistor 3, extending along the direction of the leads at both ends of the resistor 3, ensuring that the resistor 3 can be easily electrically connected to the terminal 2 after installation. Therefore, by providing the positioning groove 131 extending in the first direction within the receiving cavity 12, not only can the resistor 3 be effectively fixed, but the assembly process can also be simplified and the reliability of the overall structure improved.

[0046] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 5 As shown, a positioning plate 13 is provided inside the receiving cavity 12, and the positioning plate 13 is along the second direction (e.g. Figure 1 The positioning groove 131 extends along the second direction (perpendicular to the first direction) and is formed on the positioning plate 13, penetrating the positioning plate 13 in its thickness direction. In other words, by setting a positioning plate 13 within the receiving cavity 12, extending along the second direction (perpendicular to the first direction), and having the positioning groove 131 formed on and penetrating the positioning plate 13 in its thickness direction, the installation stability of the resistor 3 and the reliability of the overall structure are further enhanced. It is understood that by adding the positioning plate 13, additional support points are provided for the resistor 3, preventing movement or vibration in different directions. The positioning plate 13 can be rationally arranged within a limited space, making the internal structure of the connector 100 more compact and orderly. Therefore, by setting a positioning plate 13 within the receiving cavity 12 and having the positioning groove 131 penetrate the positioning plate 13, not only is the installation stability of the resistor 3 and the reliability of the overall structure further enhanced, but the assembly process is also simplified and maintenance convenience is improved.

[0047] In some embodiments of this utility model, such as Figure 5 and Figure 13 As shown, the terminal slot 121 is located on at least one side of the positioning slot 131 along its length. The terminal slot 121 communicates with the receiving cavity 12 through a connection port, and the terminal 2 extends into the terminal slot 121 through the connection port. That is, referring to... Figure 5 As shown, the terminal slot 121 can be located along the length of the positioning slot 131 (e.g., Figure 5The terminal slot 121 is located on both sides of the positioning slot 131 (in the first direction shown) and communicates with the receiving cavity 12 through the connection port, allowing the terminal 2 to extend into the terminal slot 121 through the connection port. This not only ensures a reliable electrical connection between the resistor 3 and the terminal 2, but also optimizes the compactness and ease of assembly of the overall structure. It is understood that the terminal slot 121 is used to install and fix the terminal 2, preventing it from loosening or shifting during use, ensuring that the terminal 2 can reliably contact the resistor 3 and achieve an electrical connection. The terminal slot 121 is located at both ends of the positioning slot 131 along its length, ensuring a uniform distribution of electrical connections at both ends of the resistor 3 and reducing stress concentration problems caused by eccentricity. The size and shape of the connection port match the external dimensions and shape of the terminal 2.

[0048] In other embodiments, reference is made to Figure 12 and Figure 13 As shown, the terminal slot 121 can be located along the length of the positioning slot 131 (e.g., Figure 12 On one side of the first direction shown, that is, both terminals 2 are located on the same side of the length direction of the positioning groove 131, and both terminal slots 121 are located on the same side of the length direction of the positioning groove 131, and the two terminal slots 121 are arranged apart. The resistance lead 31 of the resistor 3 at the end opposite to the terminal slot 121 has a bent portion 311, so that the resistance leads 31 at both ends of the resistor 3 can be connected to one terminal 2 respectively. As a result, not only is the electrical connection stability between the resistor 3 and the terminal 2 enhanced, but the compactness and assembly convenience of the overall structure are also optimized, and the application range and structural adjustment range of the connector 100 are broadened, thus making it suitable for more types of motors.

[0049] In some embodiments of this utility model, such as Figure 1 As shown, terminal 2 has a connecting portion 21, such as Figure 6 As shown, the connecting portion 21 is located within the receiving cavity 12. The resistor 3 has resistor leads 31 located at both ends of the resistor 3 and connected to the connecting portion 21. In other words, the connecting portion 21 of the terminal 2 is located within the receiving cavity 12, and the resistor 3 has resistor leads 31 at both ends, which are connected to the connecting portion 21 of the terminal 2. This ensures a reliable electrical connection between the resistor 3 and the terminal 2, while optimizing the compactness and ease of assembly of the overall structure. It can be understood that the connecting portion 21 is a part of the terminal 2, located within the receiving cavity 12, and is used for electrical connection with the resistor leads 31. As shown, the connecting portion 21 extends along a first direction. It can be understood that by providing the connecting portion 21 on the terminal 2 and connecting the connecting portion 21 to the resistor leads 31, the stability of the electrical connection between the resistor 3 and the terminal 2 is enhanced, better meeting the requirements of the electronics industry for stability and reliability.

[0050] In some embodiments of this utility model, such as Figure 1 As shown, there are two terminals 2, each with a connecting portion 21. There are also two resistance leads 31, each connected to a corresponding connecting portion 21. As shown, the two terminals 2 are located at opposite ends of the positioning groove 131 along its length, for electrical connection with the resistance leads 31 at both ends of the resistor 3. The two terminals 2 are symmetrically arranged at both ends of the positioning groove 131, ensuring uniform electrical connection distribution at both ends of the resistor 3 and reducing stress concentration caused by eccentricity. Each terminal 2 has a connecting portion 21 located within the receiving cavity 12 for electrical connection with the resistance lead 31. There are two resistance leads 31, located at both ends of the resistor 3, for electrical connection with the corresponding terminal 2 connecting portion 21. Therefore, by designing two terminals 2, each with a connecting portion 21, and with resistance leads 31 at both ends of the resistor 3, connected one-to-one with the connecting portions 21, this design not only enhances the electrical connection stability between the resistor 3 and the terminals 2 but also optimizes the overall structural compactness and assembly convenience.

[0051] In some embodiments of this invention, the resistor lead 31 is welded to the connecting part 21. This welding ensures a robust mechanical and electrical connection, extends service life, prevents loosening or breakage, reduces contact resistance between the resistor lead 31 and the connecting part 21, and improves electrical performance.

[0052] In some other embodiments of this utility model, the resistor lead 31 and the connecting part 21 are crimped together. The crimping connection does not require additional welding materials and the installation speed is fast.

[0053] In some other embodiments of this utility model, the resistor lead 31 and the connecting part 21 are connected by bolts, which facilitates frequent disassembly and maintenance.

[0054] In some embodiments of this utility model, such as Figure 1 and Figure 6As shown, a raised rib 15 is formed around the periphery of the connection port, and the raised rib 15 forms a relief groove 151. The connecting part 21 extends along the first direction and is located within the relief groove 151. That is, the raised rib 15 around the periphery of the connection port increases the structural strength and sealing of the connection port. The connecting part 21 is located within the relief groove 151, and the raised rib 15 provides additional protection and support for the connecting part 21. It can be understood that the raised rib 15 can increase the structural rigidity around the connection port, preventing deformation or damage during the assembly of the terminal 2. The relief groove 151 provides a dedicated space for the connecting part 21. The connecting part 21 is located within the relief groove 151, ensuring that the connecting part 21 is not subject to external interference or damage during installation and use. Furthermore, it serves to limit the position of the terminal 2. The shape and size of the connection port match the shape and size of the terminal 2, and the shape and size of the relief groove 151 match the shape and size of the connecting part 21. Therefore, by providing a rib 15 around the connection port and forming a relief groove 151 on the rib 15, the connection part 21 extends along the first direction and is located in the relief groove 151. This not only enhances the structural strength and sealing of the connection port, but also provides additional protection and support for the connection part 21 of the terminal 2.

[0055] Reference Figure 7 As shown, a support block 175 is provided on the side surface of the cover 17 facing the receiving cavity 12. The support block 175 is supported on the rib 15 to avoid compressing the resistor 3 or the terminal 2.

[0056] In some embodiments of this utility model, a first limiting portion is formed on the inner wall of the connector, and a second limiting portion is formed on the terminal 2. The first limiting portion and the second limiting portion cooperate to limit the relative position between the terminal 2 and the terminal slot 121. That is, the first limiting portion is located on the inner wall of the connector and is used to cooperate with the second limiting portion on the terminal 2 to prevent the terminal 2 from shifting or loosening during insertion; the second limiting portion is located on the terminal 2 and is used to cooperate with the first limiting portion at the connector to ensure that the terminal 2 can be accurately positioned and remain stable when inserted into the terminal slot 121. As a result, the accuracy and stability of the terminal 2 installation can be significantly improved, ensuring the reliability and mechanical strength of the electrical connection.

[0057] For example Figure 1 and Figure 5 As shown, the first limiting portion is formed as a first protrusion 14, which is located at the connection port and is located at both ends of the connection port in the length direction. The second limiting portion is formed as a second protrusion 22, which is located on both sides of the terminal 2 in the width direction. The first protrusion 14 and the second protrusion 22 are arranged correspondingly, and each of the two first protrusions 14 corresponds to one second protrusion 22. This ensures that the terminal 2 can be accurately positioned and remain stable when inserted into the terminal slot 121, and the first protrusion 14 and the second protrusion 22 cooperate to continuously limit the position of the terminal 2.

[0058] In some embodiments of this utility model, the housing 1 includes a main body 11 and a cover 17. The main body 11 and the cover 17 cooperate to define a receiving cavity 12. A clearance groove 171 is formed on the side of the cover 17 facing the receiving cavity 12. The clearance groove 171 is arranged opposite to the positioning groove 131 to accommodate the resistor 3. It can be understood that the main body 11 is the main part of the housing 1, and the cover 17 is used to close the main body 11. The cover 17 and the main body 11 cooperate to form the receiving cavity 12, ensuring the safety and stability of the internal components. The clearance groove 171 is located on the side of the cover 17 facing the receiving cavity 12 and is arranged opposite to the positioning groove 131 to accommodate the resistor 3, providing additional space and protection for the resistor 3. Furthermore, the shape and size of the clearance groove 171 match the shape and size of the resistor 3, ensuring that the resistor 3 can be placed stably. Thus, not only is the internal structural layout of the housing 1 optimized, but better protection and support are also provided for the resistor 3.

[0059] like Figure 7 As shown, the clearance groove 171 is recessed in a direction away from the receiving cavity 12.

[0060] In some embodiments of this utility model, the main body 11 has a first guide portion, and the cover 17 has a second guide portion. The main body 11 and the cover 17 cooperate through the first and second guide portions to limit the installation position between the cover 17 and the main body 11. That is, the first guide portion is formed on the main body 11, and the second guide portion is formed on the cover 17. The cooperation of the first and second guide portions limits the installation position between the cover 17 and the main body 11, thus ensuring the precise assembly of the housing 1 and improving the overall stability and sealing of the connector 100. It can be understood that the first guide portion is located on the main body 11 and is used to cooperate with the second guide portion on the cover 17 to ensure that the cover 17 can be accurately positioned during installation and prevent displacement or misalignment; the second guide portion is located on the cover 17 and cooperates with the first guide portion to ensure that the cover 17 can be accurately positioned and remain stable during installation. Therefore, by forming a first guide portion on the main body 11 and a second guide portion on the cover 17, the cooperation between the first guide portion and the second guide portion can significantly improve the installation accuracy between the cover 17 and the main body 11, ensuring the overall stability and sealing of the connector 100.

[0061] Reference Figure 1 As shown, in a specific embodiment of this utility model, the first guide portion is formed as a guide groove 16, and the guide groove 16 is along a third direction (e.g., Figure 1The second guide portion extends in a third direction (as shown), perpendicular to both the first and second directions. It is formed as a guide plate 172, with both ends adapted to extend into the guide groove 16 and slide along its extension direction. This ensures the installation accuracy between the cover 17 and the body 11, improving the reliability of the connector 100. The guide groove 16, located on the body 11, guides the guide plate 172 on the cover 17, ensuring accurate positioning of the cover 17 during installation and preventing displacement or misalignment during assembly. As shown, the guide groove 16 extends in a straight line, and the guide plate 172 also extends in a straight line. The cooperation between the guide plate 172 and the guide groove 16 significantly improves the installation accuracy and convenience between the cover 17 and the body 11, ensuring the overall stability and sealing of the connector 100, and improving assembly speed and production quality.

[0062] In some embodiments of this utility model, the receiving cavity 12 has an open opening, and a mounting groove 122 extending through the open opening is formed around its periphery. The sidewall of the mounting groove 122 forms a first positioning surface 1221, and the outer peripheral wall of the cover 17 forms a second positioning surface 173. The cover 17 and the main body 11 cooperate through the first positioning surface 1221 and the second positioning surface 173 to seal the cover 17 at the open opening. This ensures precise alignment and stable installation between the cover 17 and the main body 11, improving the overall assembly accuracy of the connector 100. (Refer to...) Figure 1 As shown, the mounting groove 122 is located around the opening of the receiving cavity 12. The sidewall of the mounting groove 122 is formed as a first positioning surface 1221, which mates with the outer peripheral wall of the cover 17 (i.e., the second positioning surface 173) to ensure that the cover 17 can be accurately positioned and tightly seal the opening. The outer peripheral wall of the cover 17 is formed as a second positioning surface 173, which mates with the first positioning surface 1221 of the mounting groove 122 to ensure that the cover 17 can be accurately installed and remain stable. This ensures the overall stability and sealing of the connector 100, reduces assembly difficulty, and increases assembly speed.

[0063] In some embodiments of this utility model, such as Figure 1As shown, the periphery of the side surface of the cover 17 facing the receiving cavity 12 forms a first sealing surface 174, and the bottom wall of the mounting groove 122 forms a second sealing surface 1222. The cover 17 and the main body 11 are sealed together by the cooperation of the first sealing surface 174 and the second sealing surface 1222. That is, the first sealing surface 174 is located on the periphery of the side surface of the cover 17 facing the receiving cavity 12, and is used to cooperate with the second sealing surface 1222 of the mounting groove 122 to form a tight sealing connection; the second sealing surface 1222 is located on the bottom wall of the mounting groove 122, and cooperates with the first sealing surface 174 of the cover 17 to ensure a tight seal between the cover 17 and the main body 11. Thus, the cooperation of the first sealing surface 174 and the second sealing surface 1222 significantly improves the sealing performance of the connector 100, ensuring the safety and reliability of the internal components of the connector 100.

[0064] The following will refer to Figures 1-14 The connector 100 according to two specific embodiments of the present invention is described.

[0065] Reference Figure 1 As shown, connector 100 includes: housing 1, terminal 2 and resistor 3. Housing 1 includes body 11 and cover 17.

[0066] Example 1,

[0067] Specifically, such as Figures 1-7 As shown, the housing 1 has a receiving cavity 12 and a terminal slot 121 communicating with the receiving cavity 12. The terminal 2 is adapted to pass through the receiving cavity 12 and extend into the terminal slot 121. The resistor 3 is located in the receiving cavity 12, and the two ends of the resistor 3 are connected to the terminal 2. A positioning plate 13 is provided in the receiving cavity 12. The positioning plate 13 extends along a second direction, which is perpendicular to the first direction. A positioning groove 131 is formed on the positioning plate 13 and penetrates the positioning plate 13 in the thickness direction (i.e., the positioning groove 131 extends along the first direction).

[0068] Two terminals 2 are included, and two terminal slots 121 are included. The two terminals 2 are located at both ends of the positioning slot 131 along its length and are used to make electrical connections with the resistance leads 31 at both ends of the resistor 3. The two terminals 2 are symmetrically arranged at both ends of the positioning slot 131 to ensure that the electrical connections at both ends of the resistor 3 are evenly distributed and to reduce stress concentration problems caused by eccentricity. Each terminal 2 has a connecting part 21 located in the receiving cavity 12 and is used to make electrical connections with the resistance leads 31. There are two resistance leads 31, located at both ends of the resistor 3 and used to make electrical connections with the corresponding terminal 2 connecting parts 21.

[0069] Terminal slot 121 and receiving cavity 12 are connected through a connection port. Terminal 2 extends into terminal slot 121 through the connection port. A rib 15 is formed around the periphery of the connection port, and the rib 15 forms a relief groove 151. The connecting part 21 extends along a first direction and is located within the relief groove 151. A first limiting part is formed as a first protrusion 14, which is located at the connection port and at both ends in the length direction of the connection port. A second limiting part is formed as a second protrusion 22, which is located on both sides in the width direction of terminal 2. The first protrusion 14 and the second protrusion 22 are arranged correspondingly, and each of the two first protrusions 14 corresponds to one second protrusion 22. A support block 175 is provided on the side surface of the cover 17 facing the receiving cavity 12. The support block 175 is supported on the rib 15 to prevent pressure on the resistor 3 or terminal 2.

[0070] The cover 17 and the main body 11 cooperate to form a receiving cavity 12, ensuring the safety and stability of the internal components. The clearance groove 171 is located on the side of the cover 17 facing the receiving cavity 12 and is arranged opposite to the positioning groove 131 to accommodate the resistor 3, providing additional space and protection for the resistor 3. The first guide portion is formed as a guide groove 16, which extends along a third direction. The third direction is perpendicular to the first direction and also perpendicular to the second direction. The second guide portion is formed as a guide plate 172, the two ends of which are adapted to extend into the guide groove 16 and slide along the extension direction of the guide groove 16. This ensures the installation accuracy between the cover 17 and the main body 11 and improves the reliability of the connector 100.

[0071] The receiving cavity 12 has an open opening, and a mounting groove 122 extending through the opening is formed around its periphery. The mounting groove 122 is located around the periphery of the open opening of the receiving cavity 12. The side wall of the mounting groove 122 is formed as a first positioning surface 1221, which is used to cooperate with the outer peripheral wall of the cover 17 (i.e., the second positioning surface 173) to ensure that the cover 17 can be accurately positioned and tightly seal the opening of the cover. A first sealing surface 174 is located around the periphery of the side surface of the cover 17 facing the receiving cavity 12, and a second sealing surface 1222 is located on the bottom wall of the mounting groove 122, cooperating with the first sealing surface 174 of the cover 17 to ensure a tight seal between the cover 17 and the body 11.

[0072] Example 2,

[0073] like Figures 8-14 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, with the same components using the same reference numerals. The only difference is that the terminal slot 121 described in Embodiment 1 is arranged on both sides of the positioning slot 131 in the first direction, while the terminal slot 121 described in this Embodiment 2 is arranged on one side of the positioning slot 131 in the first direction.

[0074] In summary, by setting the positioning groove 131 and placing the resistor 3 within the positioning groove 131, the problems of fixing and welding the resistor 3 are solved; by placing the resistor 3 within the connector 100 and covering the resistor 3 with a cover 17, the problem of insulation protection for the resistor 3 is solved; by forming a sealing surface on the cover 17 and the main body 11, the problem of injection molding sealing protection for the resistor 3 is solved, and the sealing protection effect of the resistor 3 is improved.
