Description

Technical Field

[0002] A Chinese patent with the authorization announcement number CN205609762U discloses a cold-pressed terminal, including a wiring tube and a connecting terminal. The wiring tube is provided with a wiring hole for inserting a cable, and a limiting baffle is provided at the opening of the wiring tube at one end relative to the connecting terminal. During the insertion process of the cable in the above-mentioned disclosed document, it is possible to observe through a visual port whether the cable is inserted in place and the insertion state, so it is convenient for the staff to observe until the cable is blocked by the limiting baffle at the bottom of the wiring tube and cannot be inserted further, which can avoid the cable extending beyond the end of the wiring tube from scratching the staff and even causing inconvenience in the installation of the connecting terminal. Therefore, after the limiting baffle is provided, when the staff inserts the cable to the bottom, the installation is completed, that is, the contact area between the wiring tube and the cable is maximized, thereby effectively ensuring the connection firmness.

[0003] However, during the process of connecting the terminal to the conductive sheet by screws, it is necessary to ensure that the screws are tightened. Otherwise, there will be a wobble between the terminal and the conductive sheet, which will affect the reliability of the connection between the terminal and the conductive sheet. Therefore, usually the screws are over-tightened to prevent the wobble between the terminal and the conductive sheet. However, after such over-tightening, it is not conducive to the disassembly of the terminal. Therefore, how to ensure that there is no wobble after the connection between the terminal and the conductive sheet without over-tightening the screws is a technical problem to be solved. Summary of the Utility Model

[0004] In view of the above deficiencies in the background art, the utility model provides an automotive wire harness terminal, which solves the technical problem that in the prior art, the terminal and the conductive sheet need to be over-tightened by screws to avoid wobbling between the terminal and the conductive sheet, which is not conducive to the disassembly of the terminal.

[0005] The technical solution of the utility model is realized as follows: An automotive wire harness terminal includes a wiring part and a connecting part. The wiring part and the connecting part are integrally connected, and an anti-rotation structure for blocking and cooperating with the conductive sheet is provided on the connecting part.

[0006] Preferably, the connecting part and the anti-rotation structure are integrally connected.

[0007] Preferably, two of the anti-rotation structures are oppositely arranged on the connecting part.

[0008] Preferably, the anti-rotation structure is formed by bending the connecting part after stamping.

[0009] Preferably, the anti-rotation structure is bent at 90°.

[0010] Preferably, the width of the leading end of the connecting portion is a, where a is greater than 10 mm and less than 18 mm.

[0011] Preferably, a connection hole is provided on the connecting portion.

[0012] Preferably, the connection hole is an oblong hole.

[0013] Preferably, a peephole structure is provided at the connection between the wiring portion and the connecting portion.

[0014] Preferably, a copper wire insertion chamfer is provided on the wiring portion.

[0015] Advantages of the present utility model: The present utility model provides an anti-rotation structure on the connecting portion of the terminal. After the terminal and the conductive sheet are connected by screws, the anti-rotation structure and the conductive sheet are in a blocking fit. By using the anti-rotation structure, the situation that the terminal and the conductive sheet shake after connection is avoided. It is not necessary to over-tighten the screws to prevent shaking between the terminal and the conductive sheet. The screws between the terminal and the conductive sheet only need to be tightened normally, which avoids affecting the disassembly of the terminal, and solves the technical problem in the prior art that the terminal and the conductive sheet need to be over-tightened by screws to prevent shaking between the terminal and the conductive sheet, which is not conducive to the disassembly of the terminal.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1, an automotive wiring harness terminal, as Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, includes a wiring part 1 and a connecting part 2. The wiring part 1 and the connecting part 2 are integrally connected. An anti-rotation structure 3 that is in blocking cooperation with the conductive sheet 7 is provided on the connecting part 2. By providing the anti-rotation structure 3 on the connecting part 2 of the terminal, when the terminal is connected to the conductive sheet 7 by a screw, the anti-rotation structure 3 is in blocking cooperation with the conductive sheet 7. Using the anti-rotation structure 3, the situation where the terminal and the conductive sheet 7 shake after connection is avoided. It is not necessary to over-tighten the screw to prevent shaking between the terminal and the conductive sheet 7. The screw between the terminal and the conductive sheet 7 only needs to be tightened normally, avoiding affecting the disassembly of the terminal, and solving the technical problem in the prior art that the terminal and the conductive sheet need to over-tighten the screw to prevent shaking between the terminal and the conductive sheet 7, which is not conducive to the disassembly of the terminal.

[0026] Embodiment 2, on the basis of Embodiment 1, an automotive wiring harness terminal, as Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, the connecting part 2 and the anti-rotation structure 3 are integrally connected. The integral connection of the connecting part 2 and the anti-rotation structure 3 can improve the connection strength between the connecting part 2 and the anti-rotation structure 3 and reduce the resistance of the entire automotive wiring harness terminal.

[0027] Embodiment 3, on the basis of Embodiment 2, an automotive wiring harness terminal, as Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, two of the anti-rotation structures 3 are oppositely arranged on the connecting part 2. After the terminal is connected to the conductive sheet by a screw, the two anti-rotation structures 3 on the connecting part 2 are respectively located on both sides of the conductive sheet 7 and the two anti-rotation structures 3 are respectively in blocking cooperation with the side surface of the conductive sheet 7.

[0028] Embodiment 4, on the basis of Embodiment 3, an automotive wiring harness terminal, asFigure 1 , Figure 2 , Figure 3 and Figure 6 As shown in Figure 3 and Figure 6 , the anti-rotation structure 3 is formed by bending the connecting portion 2 after stamping. The rotation structure 3 is formed by bending the connecting portion 2 after stamping. On the one hand, the rotation structure 3 and the connecting portion 2 are integrally formed by stamping, and the connection strength between the rotation structure 3 and the connecting portion 2 is high and the resistance is small. On the other hand, the rotation structure 3 is a structure formed by bending. The rotation structure 3 formed by bending is in stop cooperation with the side surface of the conductive sheet 7, that is, the rotation structure 3 and the connecting portion 2 are not in the same plane, and the rotation structure 3 and the connecting portion 2 form a connection structure that wraps and surrounds the conductive sheet 7.

[0029] Embodiment 5, on the basis of Embodiment 4, an automotive wire harness terminal, as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown in Figure 3 and Figure 6 , the anti-rotation structure 3 is bent at 90°. The anti-rotation structure 3 being bent at 90° means that the rotation structure 3 is perpendicular to the connecting portion 2, that is, the two anti-rotation structures 3 and the connecting portion 2 form a connection structure with an inverted U-shaped longitudinal section. The inverted U-shaped connection structure wraps and connects the conductive sheet 7, greatly increasing the connection area between the terminal and the conductive sheet 7, which is beneficial to ensuring the connection stability and reducing the connection resistance between the terminal and the conductive sheet 7.

[0030] Embodiment 6, on the basis of any one of Embodiments 1 to 5, an automotive wire harness terminal, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , the width of the first end of the connecting portion 2 is a, where a is greater than 10 mm and less than 18 mm. The width of the first end of the existing ordinary terminals is greater than or equal to 18 mm, which results in that the existing ordinary terminals are only applicable to installation spaces with a size greater than or equal to 18 mm. When the installation space is less than 18 mm, the existing ordinary terminals are not suitable. The width of the first end of the terminal in this application is greater than 10 mm and less than 18 mm, making the terminal in this application applicable to installation spaces with a size greater than 10 mm and less than 18 mm, that is, the terminal in this application can be used in a narrow installation space greater than 10 mm and less than 18 mm, improving the application range of the terminal.

[0031] Preferably, the dimension of the width a of the first end of the connecting portion 2 is 14.8 ± 0.2 mm, and the dimension of the diameter b of the copper wire inserted into the wiring portion 1 is ∅8.7 ± 0.2 mm.

The setting of the connection hole 6 is to facilitate the fixed connection between the terminal and the conductive sheet 7, which is beneficial to improving the connection efficiency between the connection part 2 and the conductive sheet 7.

[0033] Embodiment 8, based on Embodiment 7, an automotive wiring harness terminal, as Figure 3 and Figure 4 shown, the connection hole 6 is an oblong hole. The setting of the oblong hole makes the connection part 2 more variable and adjustable because it can usually more easily adapt to different manufacturing and assembly requirements, facilitating fixed connection even when there are certain dimensional errors when the connection part 2 is connected to the conductive sheet 7 by screws.

[0034] Embodiment 9, based on Embodiment 8, an automotive wiring harness terminal, as Figure 2 、 Figure 3 and Figure 6 shown, a peephole structure 4 is provided at the connection between the wiring part 1 and the connection part 2. The setting of the peephole structure 4 is to be able to see the crimping state of the internal copper wire, greatly improving the reliability and safety, and at the same time being beneficial to improving the assembly efficiency of the entire automotive wiring harness terminal.

[0035] Embodiment 10, based on Embodiment 1 or 9, an automotive wiring harness terminal, as Figure 2 and Figure 5 shown, a copper wire insertion chamfer 5 is provided on the wiring part 1. The setting of the copper wire insertion chamfer 5 facilitates the insertion of the copper wire into the wiring part 1, which is beneficial to improving the assembly efficiency of the entire automotive wiring harness terminal.

[0036] When implementing Embodiment 10, after integrally forming the terminal, bend the rotating structure 3 by 90°, then insert the copper wire into the wiring part 1 and press it tightly. Through the peephole structure 4, see the crimping state of the internal copper wire in the wiring part 1. After determining that the internal copper wire in the wiring part 1 is properly crimped, form the automotive wiring harness terminal of the present application. Place the automotive wiring harness terminal on the corresponding conductive sheet 7. At this time, the connection part 2 is located on the top surface of the conductive sheet 7, and the two rotating structures 3 are respectively in blocking cooperation with the two side surfaces of the conductive sheet 7. Then connect the connection part 2 to the top of the conductive sheet 7 by screws to achieve the contact conduction between the automotive wiring harness terminal and the conductive sheet 7.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
