Description

Technical Field

[0001] This utility model relates to the field of wire connector technology, and specifically to a terminal structure for a wire connector. Background Technology

[0002] The function of automotive wiring connectors is to reliably connect and transmit electrical signals or power, ensuring stable communication and power supply between various components of the automotive circuit system. In the prior art, patent CN104659511A discloses a non-circular plug terminal for automotive connectors, including a plug terminal body. One end of the plug terminal body is a contact part, and the other end is a crimping part. The wire harness is connected to the crimping part, and its contact part is used to mate with an external plug-in. However, in the prior art, the crimping part and the plug-in are interference-fitted. During installation, the crimping part needs to be installed into the plug-in with a large force. Furthermore, the contact part has a slender structure and is easily deformed. After deformation, the pins are easily bent, resulting in a reduction in contact area and an increase in resistance. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art where the contact part is long and thin and easily deformed, which leads to the bending of the pin after deformation, resulting in a reduction in contact area and an increase in resistance. Thus, this invention provides an automotive wiring harness connector that allows for easy insertion of the contact part into the plug and whose contact part is not easily deformed.

[0004] Therefore, this utility model provides a terminal structure for a wire connector, including a connecting body, a conductive end disposed at one end of the connecting body, and a wire harness connecting end disposed at the other end. The conductive end is connected to an external connector. The wire harness connecting end is provided with an extension portion for the wire harness to pass through and to wrap around the outside of the wire harness. A rubber pad for insertion into the external connector is provided between the conductive end and the wire harness connecting end.

[0005] Furthermore, the outer side of the rubber pad is provided with several extension rings, which can abut against the inner wall of the plug-in.

[0006] Furthermore, the extension includes a ring through which the wire passes and abuts against the side of the rubber end, and a wrapping plate that can be included from both sides toward the middle, the wrapping plate being arranged in an arc shape and forming an upward opening.

[0007] Furthermore, the wrapping plate is provided with an anti-slip part that abuts against the outer wall of the wire.

[0008] Furthermore, the conductive end is composed of several elastic sheets arranged in a circumferential structure, and the elastic sheets are provided with sockets for inserting pins into the plug.

[0009] Furthermore: a protective sleeve is provided on the outside of the conductive end. The protective sleeve includes a connecting sleeve and a plurality of bent pieces disposed at the end of the connecting sleeve. The bent pieces are fastened to the elastic pieces, and a fastening structure for connecting the two is provided between the bent pieces and the elastic pieces.

[0010] Furthermore, the fastening structure includes a fastening block disposed at the connecting sleeve and a fastening groove disposed at the conductive end that can be adapted to the fastening block.

[0011] Furthermore, the sidewall of the connecting sleeve is provided with a pushing piece that can abut against the outer side of the elastic sheet.

[0012] The technical solution of this utility model has the following advantages:

[0013] 1. The present invention provides a terminal structure for a wire connector. During the manufacturing process, the entire connector body is placed on a mold, and a rubber pad is directly injection molded on the mold. The product is then removed, and a crimping machine is used to crimp the wire to the extension. Finally, the crimped terminal structure can be inserted into the external connector. During the connection process, the conductive end is inserted into the round hole inside the connector, and the rubber pad fills the round hole inside the connector, thereby improving the tightness of the connection between the conductive end and the round hole inside the connector, and effectively improving the waterproof and dustproof effect of the connector. Because the rubber pad is made of soft material, during installation, the conductive end only needs to be gently inserted to fill the round hole inside the connector without the need for brute force.

[0014] 2. The terminal structure of the wire connector provided by this utility model has an extension ring on the outside of the rubber pad. The extension ring can effectively improve the sealing between the rubber pad and the inner wall of the connector, and prevent water, dust and other impurities from entering.

[0027] Example

[0028] This embodiment provides a terminal structure for a wire connector, including a connecting body 1, a conductive end 2 disposed at one end of the connecting body 1, and a wire harness connecting end 3 disposed at the other end. The conductive end 2 is connected to an external connector. The wire harness connecting end 3 is provided with an extension 4 for the wire harness to pass through and to wrap around the outside of the wire harness. A rubber pad 5 is provided between the conductive end 2 and the wire harness connecting end 3 to be inserted into the external connector.

[0029] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, during the manufacturing process, the entire connector body 1 is placed on the mold, and the rubber pad 5 is directly injection molded on the mold. Then, the product is removed, and the wire is crimped onto the extension part 4 using a crimping machine. Finally, the crimped terminal structure can be inserted into the external connector. During the connection process, the conductive end 2 is inserted into the round hole inside the connector, and the rubber pad 5 fills the round hole inside the connector, thereby improving the tightness of the connection between the conductive end 2 and the round hole inside the connector, and effectively improving the waterproof and dustproof effect of the connector. Since the material of the rubber pad 5 is relatively soft, during installation, the conductive end 2 only needs to be gently inserted, and the rubber pad 5 can fill the space where the conductive end 2 is inserted into the round hole inside the connector without using brute force.

[0030] Based on the above embodiments: a plurality of extension rings 51 are provided on the outer side of the rubber pad 5, and the extension rings 51 can abut against the inner wall of the plug-in.

[0031] The specific improvements mentioned above are as follows: Figure 3 As shown, an extension ring 51 is provided on the outside of the rubber pad 5. The extension ring 51 can effectively improve the sealing between the rubber pad 5 and the inner wall of the plug-in, and prevent water, dust and other impurities from entering.

[0032] Based on the above embodiments: the extension 4 includes a ring 41 through which the wire passes and abuts against the side of the rubber end, and a wrapping plate 42 that can be included from both sides toward the middle, the wrapping plate 42 being arranged in an arc shape and forming an upward opening.

[0033] Based on the above embodiments: the wrapping plate 42 is provided with an anti-slip part 43 that abuts against the outer wall of the wire.

[0034] The specific improvements mentioned above are as follows: Figure 3 and Figure 4 As shown, the extension 4 includes a ring 41 and a wrapping plate 42. When the wire is crimped onto the extension 4, the wire will first pass through the ring 41. Then the crimping machine will press the wrapping plate 42 down from both sides to the middle, so that the two sides of the wrapping plate 42 tightly wrap the wire. The anti-slip part 43 can improve the sliding friction between the wire and the wrapping plate 42, and prevent the wire from coming off under strong pull.

[0035] Based on the above embodiments: the conductive end 2 is composed of a plurality of elastic sheets 21 arranged in a circumferential structure, and the elastic sheets 21 are provided with sockets 22 for inserting pins in the plug-in.

[0036] Based on the above embodiments: a protective sleeve 6 is provided on the outside of the conductive end. The protective sleeve 6 includes a connecting sleeve 61 and a plurality of bent pieces 62 disposed at the end of the connecting sleeve 61. The bent pieces 62 are fastened to the elastic piece 21. A fastening structure 7 for connecting the two is provided between the bent pieces 62 and the elastic piece 21.

[0037] The specific improvements mentioned above are as follows: Figure 4 and Figure 5 As shown, multiple elastic sheets 21 arranged in a circumferential direction are provided at the conductive end 2. A male terminal on the plug is inserted into the socket 22. To better protect the elastic sheet 21, a protective sleeve 6 is provided on the outside of the elastic sheet 21. During insertion, the external pin is inserted into the socket 22, and the pin will squeeze the elastic sheet 21, causing it to deform from the middle to both sides. Due to its own elastic restoring force, the elastic sheet 21 will tightly hold the pin and contact the side wall of the pin. The protective sleeve 6 is provided with several bending pieces 62, the number of which corresponds one-to-one with the number of elastic sheets 21, and they wrap around the elastic sheet 21, effectively preventing damage to the elastic sheet 21 when the pin is inserted. The pin in this embodiment is prior art and will not be described in detail.

[0038] Based on the above embodiments: the fastening structure 7 includes a fastening block 71 disposed at the connecting sleeve 61 and a fastening groove 72 disposed at the conductive end and adapted to the fastening block 71.

[0039] The specific improvements mentioned above are as follows: Figure 4 As shown, the fastening block 71 is located at the connecting sleeve 61, and the fastening groove 72 is located at the conductive end 2. By fastening the fastening block 71 and the fastening groove 72, the connecting sleeve 61 can be firmly wrapped around the outside of the conductive end 2, thereby better protecting the conductive end 2.

[0040] Based on the above embodiments: the side wall of the connecting sleeve 61 is provided with a pushing piece 8 that can abut against the outer side of the elastic piece 21.

[0041] The specific improvements mentioned above are as follows: Figure 4 As shown, a pusher plate 8 is provided on the side wall of the connecting sleeve 61. The pusher plate 8 can apply pressure to the elastic plate 21 when the pin is inserted and the elastic plate 21 springs outward from the middle, thereby increasing the contact force between the elastic plate 21 and the pin.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
