Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness connector technology, and specifically to a male terminal structure for a connector. Background Technology
[0002] The function of male and female plug connectors is to achieve fast and reliable electrical connection and signal transmission between wire harnesses, while also having anti-misinsertion and physical protection functions. In the prior art, the utility model patent with publication number CN204130844U discloses a male and female plug connector for wire harnesses, which includes a female socket and a male head. The male head in the prior art is made of plastic. However, when the wire passes through, the side wall of the male head does not have a certain elasticity, which may cause damage to the protective film on the outside of the wire when the wire is forcibly passed through. Utility Model Content
[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art that the inner sidewall of the male connector may damage the protective film on the outside of the wire when the wire is forcibly passed through due to the lack of elasticity of its sidewall, thereby providing a male terminal structure of the connector that can protect the wire harness.
[0004] Therefore, this utility model provides a male terminal structure for a connector, including a connecting block inserted into the female socket and an elastic block disposed above the connecting block. A positioning plate that engages with the elastic block is disposed on the side of the elastic block facing away from the connecting end. A first through groove is disposed in the connecting block, a second through groove is disposed in the elastic block, and a third through groove is disposed in the positioning plate. The first through groove, the second through groove, and the third through groove are connected.
[0005] Furthermore: the connecting block and the elastic block are injection molded together, and the elastic block is provided with a plurality of extension rings that can abut against the end face of the wire. The extension rings are integrally formed with the elastic block, and the extension rings are arranged along the circumferential direction of the second through groove.
[0006] Furthermore: the connecting block is provided with an extension rod, which can pass through the elastic block and extend to the positioning plate, and the side of the extension rod facing away from the connecting block is provided with a fastening block that engages with the positioning plate.
[0007] Furthermore: the positioning plate is provided with an abutting block adapted to the fastening block, the abutting block being included in the contact surface that abuts the fastening block.
[0008] Furthermore, the fastening block is configured with a semi-circular arc shape.
[0009] Furthermore, the connecting block has a insertion ring on the side facing away from the elastic block that is inserted into the female seat.
[0010] The technical solution of this utility model has the following advantages:
[0011] 1. The present invention provides a male terminal structure for a connector, wherein an elastic block made of rubber material is provided above the connecting block. When the wire harness passes through the first through slot, the second through slot, and the third through slot in sequence, the wire harness contacts the soft end face inside the elastic block, thus ensuring that the wire harness is not scratched when passing through, and better protecting the wire harness. A positioning plate is provided above the elastic block. The positioning plate is also made of plastic and has a certain strength. The positioning plate and the connecting block clamp the elastic block in the middle position, which not only protects the wire, but also ensures that the entire male terminal has a certain strength, and avoids damage to the male terminal during wire insertion and removal.
[0012] 2. The male terminal structure of the connector provided by this utility model allows the connecting block to be placed on an injection molding machine during the manufacturing process. An elastic block is then injection molded on the machine. After removing the injection-molded connecting block and elastic block, a positioning plate is attached to the upper end of the elastic block. The entire process is highly automated, ensuring production efficiency while controlling production costs. An extension ring is provided on the inner wall of the elastic block. The inner diameter of the extension ring is smaller than the inner diameter of the first through groove. When the wire harness passes through the second through groove, the extension ring will abut against the outer end face of the wire harness. This allows the extension ring to have an interference fit with the wire harness, preventing movement of the wire harness and avoiding damage caused by forced compression. Attached Figure Description

[0023] Example
[0024] This embodiment provides a male terminal structure for a connector, including a connecting block 1 inserted into the female socket and an elastic block 2 disposed above the connecting block 1. A positioning plate 3 is disposed on the side of the elastic block 2 facing away from the connecting end and engaging with the elastic block 2. A first through groove 11 is disposed in the connecting block 1, a second through groove 21 is disposed in the elastic block 2, and a third through groove 31 is disposed in the positioning plate 3. The first through groove 11, the second through groove 21, and the third through groove 31 are connected.
[0025] The specific improvements mentioned above are as follows: Figure 1As shown, compared to the prior art, an elastic block 2 made of rubber material is set above the connecting block 1. When the wire harness passes through the first through groove 11, the second through groove 21 and the third through groove 31 in sequence, the wire harness contacts the soft end face inside the elastic block 2. This ensures that the wire harness will not be scratched when passing through, thus better protecting the wire harness. A positioning plate 3 is set above the elastic block 2. The positioning plate 3 is also made of plastic and has a certain strength. The positioning plate 3 and the connecting block 1 clamp the elastic block 2 in the middle position, which not only protects the wire, but also ensures that the entire male terminal has a certain strength, avoiding damage to the male terminal during the insertion and removal of the wire.
[0026] Based on the above embodiments: the connecting block 1 and the elastic block 2 are injection molded, and the elastic block 2 is provided with a plurality of extension rings 4 that can abut against the end face of the wire. The extension rings 4 are integrally formed with the elastic block 2, and the extension rings 4 are arranged along the circumferential direction of the second through groove 21.
[0027] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, during the manufacturing process, the connecting block 1 can be placed on the injection molding equipment, and then the elastic block 2 can be injection molded on the injection molding equipment. After the injection-molded connecting block 1 and elastic block 2 are removed, the positioning plate 3 can be fastened to the upper end of the elastic block 2. The whole process is highly automated, and while ensuring production efficiency, it can control its production cost. An extension ring 4 is provided on the inner side wall of the elastic block 2. The inner diameter of the extension ring 4 is smaller than the inner diameter of the first through groove 11. When the wire harness passes through the second through groove 21, the extension ring 4 will abut against the outer end face of the wire harness. In this way, the extension ring 4 can be interference-fitted with the wire harness to prevent the wire harness from moving and to prevent damage to the wire harness due to forced compression.
[0028] Based on the above embodiments: the connecting block 1 is provided with an extension rod 5, the extension rod 5 can pass through the elastic block 2 and extend to the positioning plate 3, and the side of the extension rod 5 facing away from the connecting block 1 is provided with a fastening block 51 that is fastened to the positioning plate 3.
[0029] Based on the above embodiments: the positioning plate 3 is provided with an abutting block 6 adapted to the fastening block 51, and the abutting block 6 is included in the contact surface 7 that abuts against the fastening block 51.
[0030] The specific improvements mentioned above are as follows: Figure 2 and Figure 3As shown, an extension rod 5 is integrally formed on the connecting block 1. The extension rod 5 passes through the elastic block 2 and engages with the positioning plate 3. The positioning plate 3 is provided with an abutment block 6, which has an abutment surface. The extension rod 5 is provided with a fastening block 51. After the elastic block 2 and the connecting block 1 are injection molded, the positioning plate 3 needs to be pressed onto the upper end of the elastic block 2. During the connection process, the extension rod 5 needs to pass through the through hole on the positioning plate 3 so that the lower end surface of the fastening block 51 abuts against the contact surface 7, thereby completing the fastening of the positioning plate 3 and the connecting block 1, and clamping the elastic block 2 between the positioning plate 3 and the connecting block 1.
[0031] Based on the above embodiments: the fastening block 51 is configured with a semi-circular arc structure.
[0032] The specific improvements mentioned above are as follows: Figure 2 As shown, the positioning plate 3 has a circular through hole, and the fastening block 51 is set in a semi-circular arc structure. When the fastening block 51 passes through the through hole, it can have enough deformation space to ensure that the fastening block 51 can smoothly contact the contact surface 7.
[0033] Based on the above embodiments: the connecting block 1 is provided with a plug ring 8 inserted into the female seat on the side facing away from the elastic block 2.
[0034] The specific improvements mentioned above are as follows: Figure 2 As shown, the male terminal can be plugged into an external female connector by means of the insertion ring 8. The female connector is an externally purchased product and will not be described further here.
[0035] 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.
