Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a terminal connector that solves the problem that the existing connectors, which require inserting the terminal bodies one by one into the insulator, result in low production efficiency and poor quality.

[0005] The purpose of this utility model is also to provide a terminal connection structure that uses the above-mentioned terminal connector.

[0006] To achieve the above objectives, the first technical solution of this utility model is as follows: a terminal connector includes a housing, a first cover, a second cover, and a terminal body disposed within the housing. The first cover and the second cover are connected to form a cavity for accommodating the terminal body. During installation, the terminal body is placed within the cavity, and the first cover and the second cover are fixed and protected by the housing.

[0007] Furthermore, a molding groove is provided on the opposite side of the first cover and the second cover; when the first cover and the second cover are connected, the molding groove and the second cover form a cavity for accommodating the terminal body.

[0008] Furthermore, a groove and a wire clamp are provided on the opposite side of the first cover and the second cover, and the forming groove is connected to the groove and the wire clamp.

[0009] Furthermore, a recessed portion is provided at one end of the forming groove away from the groove. When the terminal body is housed in the forming groove, the end away from the cable extends into the recessed portion and has a gap with the bottom of the recessed portion.

[0010] Furthermore, the inner side of the groove is provided with tooth-shaped protrusions.

[0011] Furthermore, the side of the forming groove is provided with a limiting groove, and the terminal body is provided with a limiting protrusion that cooperates with the limiting groove.

[0012] Furthermore, a limiting member is provided on the outer side of the first cover and / or the second cover, and a spring piece is provided on the outer shell to cooperate with the limiting member.

[0013] The second technical solution of this utility model is implemented as follows: a terminal connection structure includes two of the above-mentioned terminal connectors, which are inserted into each other.

[0014] Furthermore, when the two terminal connectors are inserted into each other, the first cover of one terminal connector abuts with the second cover of the other terminal connector, and the second cover of one terminal connector abuts with the first cover of the other terminal connector.

[0015] Furthermore, when the two terminal connectors are inserted into each other, the positioning element provided on the outer shell of one terminal connector contacts the inner wall of the outer shell of the other terminal connector.

[0016] Furthermore, in one of the two terminal connectors, the end of the terminal body away from the cable in one terminal connector is flat, and the end of the terminal body away from the cable in the other terminal connector is bent to form a bend.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1

[0030] The terminal connector provided in this embodiment has the following structure: Figure 1 , Figure 2 As shown, it includes an outer shell 1, a first cover 2, a second cover 3 disposed inside the outer shell 1, and a terminal body 4. The first cover 2 and the second cover 3 are connected to form a cavity for accommodating the terminal body 4. During installation, the terminal body 4 is placed in the cavity, and the first cover 2 and the second cover 3 are fixed and protected by the outer shell 1.

[0031] Based on the above structure, the terminal connector separates the first cover 2 and the second cover 3. During assembly, the terminal body 4 is first placed on the first cover 2, and then the second cover 3 is connected to it. The assembly efficiency is high, and the terminal body 4 is not easily deformed during assembly, so the quality of the terminal connector can be guaranteed.

[0032] Specifically, the first cover 2 is provided with a slot, and the second cover 3 is provided with a hook that cooperates with the slot, or the first cover 2 is provided with a hook, and the second cover 3 is provided with a slot that cooperates with the hook; in use, the hook and the slot are engaged to connect the first cover 2 and the second cover 3.

[0033] The terminal body contains at least two terminals.

[0034] like Figure 3 , Figure 4 As shown, in some embodiments of this application, a molding groove 21 is provided on the opposite side of the first cover 2 and the second cover 3; when the first cover 2 and the second cover 3 are connected, the molding groove 21 and the second cover 3 form a cavity for accommodating the terminal body 4.

[0035] The terminal body 4 is housed in the molding groove 21, which allows the first cover 2 and the second cover 3 to fit together and seal, thus achieving a sealed protection for the terminal body 4.

[0036] In some embodiments of this application, the first cover 2 and the second cover 3 are further provided with a groove 22 and a wire clamp 23 on the opposite side, and the forming groove 21 is connected to the groove 22 and the wire clamp 23.

[0037] The terminal body 4 is placed in the molding groove 21, and the cable connected to it is located in the groove 22. It is clamped and limited by the wire clamp 23 to prevent it from jumping out of the groove 22, which would be detrimental to the assembly of the first cover 2 and the second cover 3.

[0038] like Figure 5 As shown, in some embodiments of this application, a recessed portion 24 is provided at one end of the forming groove 21 away from the groove 22. When the terminal body 4 is accommodated in the forming groove 21, the end away from the cable extends into the recessed portion 24 and there is a gap between it and the bottom of the recessed portion 24.

[0039] This embodiment provides a recessed portion 24 so that the end of the terminal body 4 away from the cable extends into it, thereby limiting the end of the terminal body 4 and preventing it from moving out of the molding groove 21 during transportation and use, thus preventing the front end from lifting up.

[0040] In some embodiments of this application, the inner side of the groove 22 is provided with toothed protrusions 221.

[0041] When the first cover 2 and the second cover 3 are connected, the toothed protrusion 221 presses against the outside of the cable, increasing the friction and connection strength between the cable and the groove 22. During use, the terminal body 4 will not detach from the cable, ensuring the effectiveness of the terminal connector.

[0042] In some embodiments of this application, the side of the forming groove 21 is provided with a limiting groove 211, and the terminal body 4 is provided with a limiting protrusion 41 that cooperates with the limiting groove 211.

[0043] In this embodiment, the limiting protrusion 41 is located in the limiting groove 211 to limit the axial position of the terminal body 4, which can prevent the terminal body 4 from moving forward or backward in the first cover 2, thus ensuring the connection stability and performance of the terminal connector.

[0044] In some embodiments of this application, a limiting member 25 is provided on the outer side of the first cover 2 and / or the second cover 3, and a spring piece 11 that cooperates with the limiting member 25 is provided on the outer shell 1.

[0045] In this embodiment, the limiting member 25 is a groove that cooperates with the spring piece 11. When the first cover 2 and the second cover 3 are connected, they will squeeze the spring piece 11 and deform it when they are inserted into the outer shell 1. When they reach the corresponding position, the spring piece 11 returns to its original position and abuts in the groove that serves as the limiting member 25, thereby limiting the relative positions of the first cover 2, the second cover 3 and the outer shell 1.

[0046] The specific method for using the connector provided in this embodiment is as follows:

[0047] When assembling the terminal connector, first connect the rear end of the terminal body 4 to the cable, then extend the front end of the terminal body 4 into the recess 24. The terminal body 4 is accommodated in the molding groove 21 on the first cover 2, and the cable is accommodated in the groove 22 and the wire clamp 23. Then, the first cover 2 and the second cover 3 are connected and inserted into the outer shell 1. At this time, the spring piece 11 on the outer shell 1 cooperates with the limiting member 25.

[0048] Example 2

[0049] The terminal connection structure provided in this embodiment is as follows: Figure 6 , Figure 7 As shown, it includes two terminal connectors as described in Embodiment 1, and the two terminal connectors are inserted into each other.

[0050] When this terminal connection structure is in use, the two terminal connectors are inserted as male and female terminal connectors respectively, so that the terminal bodies of the two are in contact to realize the transmission of signals or current.

[0051] In some embodiments of this application, when the two terminal connectors are inserted into each other, the first cover 2 of one terminal connector is mated with the second cover 3 of the other terminal connector, and the second cover 3 of one terminal connector is mated with the first cover 2 of the other terminal connector.

[0052] When two terminal connectors are inserted, the two terminal bodies 4 need to be in contact. Therefore, the length of the first cover 2 is longer than the length of the second cover 3. After the two are connected, a part of the end of the terminal body 4 is exposed. The first cover 2 and the second cover 3 of one of the two terminal connectors are flipped so that the first cover 2 is connected to the second cover 3 of the other terminal connector, and the second cover 3 is connected to the first cover 2 of the other terminal connector, thereby realizing the connection of the two terminal bodies 4 in the terminal connection structure.

[0053] In some embodiments of this application, when two terminal connectors are inserted into each other, the positioning member 12 provided on the outer shell 1 of one terminal connector contacts the inner wall of the outer shell 1 of the other terminal connector.

[0054] Specifically, the positioning element 12 is at least one set of positioning protrusions symmetrically arranged on the outside of the outer shell 1 of one of the terminal connectors. When the two terminal connectors are inserted together, the symmetrical positioning protrusions can ensure that the outer shell 1 of one terminal connector is aligned with the middle position of the outer shell 1 of the other terminal connector, which facilitates the insertion of the two connectors.

[0055] like Figure 8 As shown, in some embodiments of this application, in one of the two terminal connectors, the end of the terminal body 4 away from the cable in one terminal connector is flat, and the end of the terminal body 4 away from the cable in the other terminal connector is bent to form a bend 42.

[0056] That is, the terminal bodies 4 of the two terminal connectors have different end structures. When they are used together, the bent part 42 has a certain deformation ability and can make close contact with the flat terminal body 4 to ensure the contact stability of the two terminal bodies 4 and the transmission effect of current and signal.

[0057] This application also allows for a gap between the bottom of the terminal body 4 and the recessed portion 24, providing redundant space for the deformation of the terminal body 4, preventing the recessed portion 24 from restricting the deformation of the terminal body 4 and causing it to protrude too much, thus ensuring the effectiveness of the terminal connection structure.

[0058] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
