Description

Technical Field

[0001] The utility model relates to the technical field of wire harness connection, in particular to a wire harness connection terminal. Background Art

[0002] Common methods for designing automotive wiring harness connections include ultrasonic welding, terminal crimping, J / C connectors, soldering, etc. Among them, terminal crimping is the physical crimping of the wire harness copper wire evenly through the terminal, which is currently the most commonly used connection method.

[0003] The terminal block is generally made of brass, and the part for crimping the copper wire of the wire harness includes a U-shaped supporting part at the bottom for supporting the copper wire, and two crimping parts extending upward from both sides of the supporting part. The ends of the two crimping parts extend upward in a trumpet shape, or the ends of the two crimping parts extend upward in an inward curling shape. There is a gap between the two crimping parts of both structures. Although both structures have the advantages of easy operation, high efficiency, good conductivity and economy, the terminal of the above structure still has a defect in the process of crimping the wire harness, that is, the copper wire of the wire harness is easily exposed from the gap between the ends of the two crimping parts, resulting in incomplete crimping of the copper wire, affecting normal use, or the operator needs to pay special attention to the operation of this step during use to prevent the copper wire from not being completely pressed into the supporting part of the terminal and the two crimping parts, but this undoubtedly increases the difficulty of operation for the operator and affects work efficiency. Utility Model Content

[0004] In order to solve the technical problem that the existing wiring terminal in the above background technology has a gap between the two wire crimping parts, resulting in the copper wire in the wiring terminal being easily exposed and difficult to be completely pressed when crimping the wiring harness, the utility model provides a wiring harness wiring terminal.

[0005] The technical solution of this utility model is as follows:

[0006] A wire harness terminal comprises a terminal body, the terminal body comprises a crimping structure located in the middle thereof, and the crimping structure is configured to wrap the wire core of the wire harness, the crimping structure comprises a supporting portion and a wire pressing portion, the supporting portion is an arc-shaped sheet structure with an opening toward the wire pressing portion, the wire pressing portion comprises two wire pressing pieces arranged on both sides of the supporting portion, the two wire pressing pieces are bent toward each other on one side away from the supporting portion, and one of the wire pressing pieces is bent to the inner side of the other wire pressing piece.

[0007] Compared with the wiring harness terminal in the prior art in which there is a gap between the two crimping parts, the wiring harness terminal can wrap the wire core of the wire harness through the crimping structure, which can prevent the wire core from being exposed from the gap between the two crimping parts, reducing the risk of poor contact or short circuit caused by the exposure of the wire core, thereby ensuring the stability and conductive performance of the wire harness connection, while reducing the operating difficulty of the operator and improving work efficiency.

[0008] As a wiring harness terminal as described above, as a preferred embodiment, both crimping members are arc-shaped structures with their openings facing the supporting portion. The arc-shaped structure of the supporting portion and the curved arrangement of the crimping members on both sides can better adapt to wiring harnesses of different diameters, and the curved crimping members can provide a stronger and tighter crimping effect.

[0009] Furthermore, the length of the overlapping portion of the two crimping members is not less than 1 / 3 of the opening size of the supporting portion. Such a design enhances the crimping strength and further prevents the wire core from slipping off.

[0010] As a preferred embodiment, a plurality of protrusions are provided on the inner sides of the supporting part and the wire pressing part, which can increase the friction between the inner sides of the supporting part and the wire pressing part and the wire core to ensure that the wire harness is more stable after crimping, thereby improving the quality of the conductive connection.

[0011] In order to improve the overall strength of the wiring harness terminal, the thickness of the two crimping pieces is 0.2mm-0.5mm to facilitate crimping, ensuring that the wiring harness terminal has sufficient strength and good conductivity during the crimping process, and will not be difficult to crimp due to excessively thick materials or easily damaged due to excessively thin materials, thereby improving the reliability of the connection and work efficiency.

[0012] Furthermore, the width of the two crimping pieces is 3mm-6mm to accommodate wire harnesses of different diameters, providing a larger contact area for the crimped wire harnesses, preventing the crimping part from being deformed or damaged during use, and ensuring the reliability of the connection.

[0013] To ensure that the supporting part and the two wire crimping pieces have equal strength, the thickness of the supporting part and the two wire crimping pieces are set to be equal. The uniform thickness ensures manufacturing consistency and reliability to ensure that the supporting part and the two wire crimping pieces have equal strength and good conductivity.

[0014] Furthermore, the width of the two wire crimping members close to the supporting portion is greater than the width of the side away from the supporting portion to improve the strength of the two wire crimping members. By designing the wire crimping members to have a larger width close to the supporting portion, it can be ensured that the wire core is fully crimped, reducing invalid gaps and improving electrical performance.

[0015] In the wiring harness terminal as described above, the maximum linear dimension between the wire pressing piece arranged near the supporting part and the supporting part is not less than 1 / 5 of the opening dimension of the supporting part to facilitate the insertion of the wire core.

[0016] In order to improve the durability of the wiring harness terminal, the supporting part and the wire pressing part are manufactured as one piece, which simplifies the production process, improves production efficiency, and also ensures the integrity and durability of the crimping structure.

[0017] The beneficial effect of the utility model is that the utility model provides a wiring harness terminal, which can completely wrap the wire core of the wiring harness through the crimping structure, which can prevent the wire core from being exposed from the gap between the two crimping parts, reducing the risk of poor contact or short circuit caused by the exposure of the wire core, thereby ensuring the stability of the wiring harness connection and the conductive performance, while reducing the operator's operating difficulty and improving work efficiency.

[0023] Combination Figure 1 The present embodiment provides a wiring harness terminal, wherein the terminal body 1 mainly includes a wiring harness insulation layer connection structure 12 and a mounting hole 11 located at both ends thereof, and a crimping structure 13 located in the middle thereof. The wiring harness insulation layer connection structure 12 is used to fix the insulation layer of the wiring harness, the mounting hole 11 is used to connect with other electrical components, and the crimping structure 13 is used to fix the wire core of the wiring harness.

[0024] As the core technical concept of this embodiment, the crimping structure 13 is configured to be able to wrap the wire core of the wire harness. The crimping structure 13 includes a supporting portion 131 and a wire crimping portion. The supporting portion 131 is an arc-shaped sheet structure with an opening toward the wire crimping portion. The wire crimping portion includes two wire crimping pieces arranged on both sides of the supporting portion 131. The two wire crimping pieces are bent toward each other on one side away from the supporting portion 131, and one of the wire crimping pieces is bent to the inner side of the other wire crimping piece.

[0025] Compared with the wire harness terminal in the prior art in which there is a gap between the two crimping parts, the wire harness terminal in this embodiment can wrap the wire core of the wire harness through the crimping structure 13, which can prevent the wire core from being exposed from the gap between the two crimping parts, reducing the risk of poor contact or short circuit caused by the exposure of the wire core, thereby ensuring the stability and conductive performance of the wire harness connection, while reducing the operating difficulty of the operator and improving work efficiency.

[0026] Combination Figure 2 The two wire pressing pieces are a first wire pressing piece 132 and a second wire pressing piece 133. Both of the first wire pressing piece 132 and the second wire pressing piece 133 are arc-shaped structures with their openings facing the supporting portion 131. The arc-shaped structure of the supporting portion 131 and the curved arrangement of the wire pressing pieces on both sides can better adapt to wire harnesses of different diameters, and the curved wire pressing pieces can provide a stronger and tighter crimping effect.

[0027] In order to improve the overall strength of the wiring harness terminal, the present embodiment specifically makes the following arrangements:

[0028] In this embodiment, the length of the overlapping portion of the first crimping member 132 and the second crimping member 133 is not less than 1 / 3 of the opening size of the supporting portion 131. Such a design enhances the crimping strength and further prevents the wire core from slipping off.

[0029] In this embodiment, the thickness of the first crimping piece 132 and the second crimping piece 133 are both 0.2mm-0.5mm, which is convenient for crimping. This ensures that the wiring harness terminal has sufficient strength and good conductivity during the crimping process, and does not cause crimping difficulties due to excessively thick materials or easy damage due to excessively thin materials, thereby improving the reliability of the connection and work efficiency.

[0030] Preferably, the supporting portion 131 , the first wire pressing member 132 and the second wire pressing member 133 are all of equal thickness. The uniform thickness ensures manufacturing consistency and reliability, while ensuring equal strength and good conductivity of the supporting portion 131 and the two wire pressing members.

[0031] In this embodiment, the width of the first crimping piece 132 and the second crimping piece 133 are both 3mm-6mm to accommodate wire harnesses of different diameters, provide a larger contact area for crimping the wire harnesses, prevent the crimping part from being deformed or damaged during use, and ensure the reliability of the connection.

[0032] As a further preferred embodiment, the width of the first wire crimping piece 132 and the second wire crimping piece 133 close to the supporting portion 131 is greater than the width on the side away from the supporting portion 131, so as to improve the strength of the two wire crimping pieces. By designing the wire crimping pieces to have a larger width close to the supporting portion 131, it can be ensured that the wire core is fully crimped, reducing invalid gaps and improving electrical performance.

[0033] Furthermore, the maximum linear dimension between the first wire pressing member 132 disposed near the supporting portion 131 and the supporting portion 131 is not less than 1 / 5 of the opening dimension of the supporting portion 131 to facilitate the insertion of the wire core.

[0034] In order to improve the crimping connection strength of the wire harness, a number of protrusions are provided on the inner sides of the supporting part 131 and the wire pressing part. These protrusions can increase the friction between the inner sides of the supporting part 131 and the wire pressing part and the wire core to ensure that the wire harness is more stable after crimping, thereby improving the quality of the conductive connection.

[0035] In order to improve the durability of the wiring harness terminal, the supporting portion 131 and the wire crimping portion are manufactured as one piece, which simplifies the production process, improves production efficiency, and also ensures the integrity and durability of the crimping structure 13.

[0036] The utility model discloses a wiring harness terminal, which can completely wrap the wire core of the wiring harness through the provided crimping structure 13, which can prevent the wire core from being exposed from the gap between the two crimping pieces, and reduce the risk of poor contact or short circuit caused by the exposure of the wire core, thereby ensuring the stability and conductive performance of the wiring harness connection, while reducing the operator's operating difficulty and improving work efficiency.
