Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to a structurally robust connector assembly. Background Technology
[0002] Connectors, also known as plugs or sockets, are generally electrical connectors. They are devices that connect two active devices to transmit current or signals. They can be categorized into many different types based on their application, installation method, special structure, and special performance characteristics, and are frequently mentioned in publications and manufacturers' promotional materials. They primarily use male and female connectors to connect and transmit data.
[0003] In existing connector assemblies, the female terminals are typically molded onto the insulator using an inlay molding process and extend into the insertion cavity. Because the female terminals need to extend a certain distance into the insertion cavity, the terminal fixing structure is not stable enough. During the mating process, when the terminals come into contact with the male connector, they are prone to shifting and deforming to one side due to inaccurate mating. This not only makes the mating process troublesome but also damages the terminal structure, thus affecting the overall service life. Therefore, it is necessary to further improve the existing connector structure. Utility Model Content
[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a structurally robust connector assembly that can effectively solve the problems of unstable terminal structure, cumbersome insertion process, and short service life in existing connectors.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A robust connector assembly includes a female connector and a male connector that are plugged together. The female connector includes a first body and a terminal. The first body has a insertion cavity with an open front end. A radially extending fixing groove is recessed inward at the rear end of the first body. A through hole communicating with the insertion cavity is formed at the bottom of the fixing groove. The terminal includes a fixing part that mates with the fixing groove and a plug-in part that extends forward from the fixing part. The plug-in part extends inward into the insertion cavity through the through hole. The male connector includes a second body and a plug-in member. The plug-in end of the second body mates with the insertion cavity. The plug-in member is disposed in the second body and is plugged into the plug-in part.
[0007] As a preferred embodiment, the side wall of the fixing groove is recessed inward to form a first glue groove, which is connected to the through hole, and a first glue sealant is provided in the first glue groove.
[0008] As a preferred embodiment, a fixing member is provided at the rear end of the first main body. The fixing member is embedded in the first main body, and the rear end of the fixing member is bent outward to form a fixing foot that cooperates with the outside. The fixing foot is provided with a fixing hole that cooperates with the outside.
[0009] As a preferred embodiment, the first main body has a buckle hole that connects to the insertion cavity, the second main body has an elastic arm, the outer end of the elastic arm is provided with a pressing part, and the elastic arm has a buckle part integrally formed to cooperate with the buckle hole.
[0010] As a preferred option, the second body is provided with a relief surface, and the elastic arm is disposed on the relief surface. When the male head is inserted into the female head, the elastic arm is located in the insertion cavity.
[0011] As a preferred option, the terminals are arranged in two symmetrical horizontal arrangements, and correspondingly, there are also two connectors, each connector being plugged into the corresponding terminal.
[0012] As a preferred embodiment, the second body has an installation cavity, and the connector is disposed in the installation cavity and crimped together with the external wire harness.
[0013] As a preferred embodiment, the rear end sidewall of the mounting cavity is recessed to form a second glue groove, the second glue groove is connected to the mounting cavity, and a second glue seal is provided in the second glue groove.
[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:
[0015] A radially extending fixing groove is provided recessed inward at the rear end of the first body, and the terminal includes a fixing part that mates with the fixing groove and a plug-in part that extends forward from the fixing part. The plug-in part extends inward into the insertion cavity through a through hole, so that the cooperation between the fixing groove and the fixing part increases the structural stability of the terminal on the first body, and prevents the position of the plug-in part in the insertion cavity from being shifted by external force. This not only makes the insertion process more convenient, but also makes it less likely for the terminal to deform, thus ensuring the overall service life.

[0035] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which includes a female connector 10 and a male connector 20 that are inserted together.
[0036] The female connector 10 includes a first body 11 and a terminal 12. The first body 11 has an insertion cavity 101 with an open front end. The rear end of the first body 11 is recessed inward and has a radially extending fixing groove 102. The bottom of the fixing groove 102 has a through hole 103 communicating with the insertion cavity 101. The terminal 12 includes a fixing part 121 that cooperates with the fixing groove 102 and a plug-in part 122 that extends forward from the fixing part 121. The plug-in part 122 extends inward into the insertion cavity 101 through the through hole 103. In this embodiment, a first adhesive groove 104 is recessed inward on the side wall of the fixing groove 102. The first adhesive groove 104 communicates with the through hole 103. A first adhesive sealant 13 is provided in the first adhesive groove 104. The first adhesive sealant 13 can not only further fix the fixing part 121, but also seal the gap between the fixing part 121 and the through hole 103, preventing external moisture from entering the insertion cavity 101 through the through hole 103, thus increasing its waterproof performance. The first adhesive sealant 13 is epoxy resin adhesive. A fixing member 14 is provided at the rear end of the first body 11. The fixing member 14 is embedded in the first body 11. The rear end of the fixing member 14 is bent outward to form a fixing foot 141 that mates with the outside. The fixing foot 141 has a fixing hole 105 that mates with the outside. The fixing member 14 is used to increase the installation stability between the female seat 10 and the outside. A snap hole 106 communicating with the insertion cavity 101 is provided on the first body 11. The terminals 12 are two that are arranged symmetrically in the horizontal direction.
[0037] The male connector 20 includes a second body 21 and a connector 22. The connector end of the second body 21 mates with the insertion cavity 101, and the connector 22 is disposed in the second body 21 and mates with the insertion part 122. In this embodiment, the second body 21 is provided with an elastic arm 23, and the outer end of the elastic arm 23 is provided with a pressing part 231. The elastic arm 23 is integrally formed with a fastening part 232 that mates with the fastening hole 106. When the female connector 10 and the male connector 20 are inserted, the fastening part 232 and the fastening hole 106 lock the male connector 20 and the female connector 10 together, thereby increasing the stability of the insertion structure between the female connector 10 and the male connector 20 and preventing the connector from falling off during the insertion process. The second main body 21 is provided with a clearance surface 211, and the elastic arm 23 is disposed on the clearance surface 211. When the male connector 20 is inserted into the female connector 10, the elastic arm 23 is located in the insertion cavity 101, thus hiding the elastic arm 23 in the insertion cavity 101, which not only improves the integrity but also avoids increasing the overall size of the connecting assembly during insertion. Two connectors 22 are also provided, each connector 22 being inserted into a corresponding terminal 12. An installation cavity 201 is formed inside the second main body 21, and the connector 22 is disposed in the installation cavity 201 and crimped together with the external wire harness 30. A second adhesive groove 202 is recessed into the rear side wall of the installation cavity 201, communicating with the installation cavity 201. A second adhesive sealant 24 is disposed within the second adhesive groove 202, sealing the gap at the connection between the external wire harness 30 and the installation cavity 201, further increasing its waterproof performance.
[0038] The key design feature of this invention is that a radially extending fixing groove is recessed inward at the rear end of the first main body, and the terminal includes a fixing part that mates with the fixing groove and a plug-in part that extends forward from the fixing part. The plug-in part extends inward into the insertion cavity through a through hole, thereby increasing the structural stability of the terminal on the first main body through the mate between the fixing groove and the fixing part. This prevents the position of the plug-in part in the insertion cavity from being shifted by external force, making the insertion process more convenient and also preventing the terminal from deforming, thus ensuring the overall service life.
[0039] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
