[0002] In electronic circuits, connectors are used to connect with opposing components. A nut is fitted onto the connector to connect it to the opposing component, thus achieving the connection. In existing technology, the nut is prone to detaching from the connector, requiring the nut to be found and fitted onto the connector before connecting it to the opposing component during on-site assembly. This method results in low assembly efficiency.
[0003] Therefore, a connector assembly stop structure is needed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a connector assembly stop structure that can improve assembly efficiency.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] The connector assembly stop structure includes:
[0007] A connector, wherein one end of the connector is provided with a PIN pin, the other end of the connector is provided with a wire connected to the PIN pin, and the outer peripheral surface of the connector is provided with a first limiting part;
[0008] A limiting protrusion is fixedly disposed on the connector, and the limiting protrusion is spaced apart from the first limiting part;
[0009] A nut, which is fitted onto the connector, has a second limiting portion located between a first limiting portion and a limiting protrusion. The first limiting portion and the limiting protrusion are used to limit the position of the nut on the connector.
[0010] In some embodiments, a plurality of the limiting protrusions are provided at circumferential intervals along the connector.
[0011] In some embodiments, the limiting protrusion and the connector are an integrated structure.
[0012] In some embodiments, the limiting protrusion has a first guide slope on the side opposite to the first limiting portion, and the second limiting portion has a second guide slope that cooperates with the first guide slope.
[0013] In some embodiments, three through holes are provided on the connector along its axial direction.
[0014] In some embodiments, the connector is provided with a triangular member, the three edges of which are connected to the wall of the connector to form three receiving spaces, each receiving space corresponding to a wire hole.
[0015] In some embodiments, the triangular member and the connector are an integrated structure.
[0016] In some embodiments, the outer peripheral surface of the nut is a corrugated surface.
[0017] In some embodiments, a plurality of weight-reducing grooves are formed on the first limiting portion along the circumference of the connector.
[0018] In some embodiments, the connector is provided with reinforcing ribs, which are located in the weight-reducing groove.
[0019] The beneficial effects of this utility model are:
[0020] This utility model provides a connector assembly stop structure, in which PIN pins and wires for electrical connection are respectively provided at both ends of the connector, and a first limiting part is provided around the outer periphery of the connector. A limiting protrusion is fixedly provided on the connector, and the limiting protrusion and the first limiting part are spaced apart. A nut is sleeved on the connector, and the nut has a second limiting part. The second limiting part is located between the first limiting part and the limiting protrusion.

[0032] In the process of using nuts to mate and secure connectors to their counterparts, in order to improve assembly efficiency, such as... Figs. 1-3 As shown, this utility model provides a connector assembly stop structure. The connector assembly stop structure includes a connector 1, a limiting protrusion 3, and a nut 2.
[0033] The connector 1 has a PIN pin at one end and a wire connected to the PIN pin at the other end. A first limiting portion 11 is provided around the outer periphery of the connector 1. A limiting protrusion 3 is fixedly disposed on the connector 1, and the limiting protrusion 3 is spaced apart from the first limiting portion 11. A nut 2 is fitted onto the connector 1 and has a second limiting portion located between the first limiting portion 11 and the limiting protrusion 3. The first limiting portion 11 and the limiting protrusion 3 limit the position of the nut 2 on the connector 1.
[0034] With the above settings, the first limiting part 11 and the limiting protrusion 3 on the connector 1 can be used to restrict the movement of the nut 2 in the axial direction of the connector 1. Since the first limiting part 11 and the limiting protrusion 3 restrict the nut 2, the nut 2 cannot fall off the connector 1. Therefore, when assembling the connector 1 with the other part, the nut 2 can be directly screwed to the other part, thus improving assembly efficiency.
[0035] In some embodiments, a plurality of limiting protrusions 3 are provided at circumferential intervals along the connector 1. In this embodiment, two limiting protrusions 3 are provided at equal intervals on the connector 1. The two limiting protrusions 3 can further and effectively block the nut 2, thereby preventing the nut 2 from falling off the connector 1. In other embodiments, no less than three limiting protrusions 3 may be provided on the connector 1 as needed, and no further restrictions are imposed here.
[0036] In some embodiments, the limiting protrusion 3 and the connector 1 are an integral structure. Specifically, the limiting protrusion 3 and the connector 1 can be integrally molded using injection molding, ensuring a stable connection between the limiting protrusion 3 and the connector 1, while also saving assembly steps and further ensuring assembly efficiency. Both the connector 1 and the limiting protrusion 3 are made of plastic and have a certain degree of elastic deformation capability, facilitating the installation of the nut 2 on the connector 1.
[0037] In some embodiments, a first guide slope 31 is provided on the side of the limiting protrusion 3 facing away from the first limiting part 11, and the second limiting part has a second guide slope 22 that cooperates with the first guide slope 31. With this arrangement, during the process of inserting the nut 2 onto the connector 1, the second guide slope 22 cooperates with the first guide slope 31, and the first guide slope 31 serves as a guide, facilitating the compression of the limiting protrusion 3 until the second guide slope 22 separates from the first guide slope 31, at which point the nut 2 is properly fitted. At this time, the limiting protrusion 3 serves to prevent the nut 2 from coming off.
[0038] In some embodiments, three through holes 12 are provided on the connector 1 along its axial direction. These three through holes 12 guide and limit the installation of the wires, facilitating the threading and installation of the wires. One of the three through holes 12 is used for the live wire, one for the neutral wire, and the other for the ground wire.
[0039] In some embodiments, the connector 1 is provided with a triangular member 13, and the three edges of the triangular member 13 are connected to the wall surface of the connector 1 to form three receiving spaces, each receiving space corresponding to a wire hole 12. By providing the triangular member 13, the neutral wire, the live wire and the ground wire are separated into different receiving spaces.
[0040] In some embodiments, the triangular member 13 and the connector 1 are an integral structure. Specifically, the triangular member 13 and the connector 1 can be integrally molded using an injection molding process. This ensures a stable connection between the triangular member 13 and the connector 1 while saving installation steps, thereby ensuring assembly efficiency.
[0041] In some embodiments, the outer peripheral surface of the nut 2 is a corrugated surface 21. By designing the outer peripheral surface of the nut 2 as corrugated, slippage can be avoided during the tightening process, ensuring that the nut 2 is quickly tightened into place with the workpiece. In other embodiments, anti-slip protrusions, anti-slip patterns, or anti-slip grooves can also be provided on the surface of the nut 2 to increase the coefficient of friction between the hand and the nut 2, making it easier to tighten the nut 2.
[0042] In some embodiments, a plurality of weight-reducing grooves 14 are formed on the first limiting portion 11 along the circumference of the connector 1. Since the connector 1 is manufactured by injection molding, the injection molding material is relatively thick at the location where the first limiting portion 11 is provided. After injection molding, the first limiting portion 11 is at risk of shrinkage and deformation. By forming the weight-reducing grooves 14, on the one hand, the weight of the connector 1 can be reduced, and the use of injection molding material can be saved; on the other hand, it can prevent the first limiting portion 11 from shrinking and deforming.
[0043] In some embodiments, the connector 1 is provided with a reinforcing rib 15, which is located in the weight-reducing groove 14. By providing the reinforcing rib 15, the strength of the connector 1 can be further improved, and shrinkage deformation at the weight-reducing groove 14 can be further prevented, ensuring that the shape and structure of the connector 1 are stable after injection molding. In this embodiment, the reinforcing rib 15 is a cross-shaped rib; in other embodiments, it can be designed into other shapes according to actual needs, and no further restrictions are imposed here.
[0044] The assembly process of this connector assembly stop structure is as follows:
[0045] First, move the nut 2 from one end of the connector 1 so that the nut 2 is fitted onto the connector 1 to form an integral structure. Then, it can be threaded to the other part, thereby using the nut 2 to fix the connector 1 and the other part.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
