However, these terminals have poor bending resistance and are unable to effectively protect them from damage. In particular, they are susceptible to external forces and become skewed during transportation and assembly. During assembly of the male and female ends of a wiring harness connector, due to the smaller diameter of the female end's insertion hole, a skewed plug terminal can hinder smooth assembly and may even break, affecting the reliability of the wiring harness connector and causing malfunctions in the vehicle.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0032] like Figure 1 As shown, this embodiment provides a wiring harness connector, which includes a male terminal 1 and a female terminal 2. The female terminal 2 includes a female end housing 21 and a plug hole 23 provided in the female end housing 21. A socket terminal 22 is installed in the plug hole 23. The male terminal 1 includes a male end housing 11 and a plug terminal 12 located in the male end housing 11. The plug terminal 12 is plugged into the plug hole 23 to electrically connect with the corresponding socket terminal 22, thereby realizing plug-in mating between the male terminal 1 and the female terminal 2.

[0033] In existing wiring harness connectors, the male end plug terminal is typically designed as a slender, sheet-like structure to facilitate the transmission of current and signals. However, the plug terminal has poor bending resistance and cannot effectively protect the plug terminal from damage. In particular, the plug terminal is easily distorted by external forces during transportation and assembly. When the male and female ends of the wiring harness connector are assembled, due to the smaller diameter of the female end's plug hole, a distorted plug terminal is difficult to assemble smoothly and may even cause the plug terminal to break, affecting the reliability of the wiring harness connector and causing malfunction of the entire vehicle.

[0034] To solve the above problems, Figure 1 As shown, this embodiment also proposes a male terminal head 1, which includes the male terminal sheath 11 and the plug terminal 12, and also includes a guide assembly, the guide assembly includes a limiter 13 and an elastic member 14, the limiter 13 is guided by the elastic member 14 along the length direction of the plug terminal 12 ( Figure 1The retaining member 13 is slidably mounted within the male end housing 11 (in the cd directions). The retaining member 13 defines a retaining hole 131, through which the plug terminal 12 can move and mate with the female end 2. The retaining member 13 is slidably mounted within the male end housing 11 via an elastic member 14. The plug terminal 12 can move through the retaining hole 131 on the retaining member 13, so that the retaining member 13 limits the position of the plug terminals 12, maintaining a stable spacing between adjacent plug terminals 12 and preventing the plug terminals 12 from skewing or deforming. This protects the plug terminals 12 while ensuring precise mating between the plug terminals 12 and the receptacle terminals 22, thereby improving the mating accuracy between the male end 1 and the female end 2. The cd direction is perpendicular to the ab direction.

[0035] Specifically, the inner side of the male end sheath 11 is along Figure 1 There are multiple plug terminals 12 arranged in the ab direction, and the inner side of the female end sheath 21 is along the Figure 1 Multiple insertion holes 23 are arranged in corresponding intervals along the ab direction, and the number of plug terminals 12 is the same as the number of insertion holes 23. Each plug terminal 12 is inserted into a limiting hole 131 of the limiting member 13 to provide protection for the plug terminal 12 and prevent deformation and misalignment during insertion.

[0036] When the male end 1 and the female end 2 of the wiring harness connector are plugged in, the plug terminal 12 and the socket terminal 22 approach each other, the mating plane of the female end sheath 21 contacts and squeezes the limiter 13, and the elastic member 14 is compressed. The plug terminal 12 moves relative to the limiter hole 131 and plugs into the plug hole 23. After the plug terminal 12 and the socket terminal 22 are plugged in, the male end 1 and the female end 2 complete the plugging operation. At this time, the compression of the elastic member 14 is the maximum. When the male end 1 and the female end 2 are separated, the limiter 13 returns to its initial position under the action of the elastic restoring force of the elastic member 14. At this time, the limiter 13 is close to the free end of the plug terminal 12 to improve the protection of the plug terminal 12.

[0037] like Figure 1As shown, the inner wall of the male end sheath 11 is provided with a slide groove 111 along the length direction of the plug terminal 12, and the end of the limiter 13 along the length direction is slidably provided in the slide groove 111. The elastic member 14 is retractably installed in the slide groove 111, and one end of the elastic member 14 is elastically connected to the limiter 13. The slide groove 111 extends along the cd direction. Through the sliding cooperation between the limiter 13 and the slide groove 111, the guide and limit function of the limiter 13 is realized, so that the limiter 13 can slide reliably in the cd direction in the slide groove 111. When the male terminal 1 is plugged into the female terminal 2, the plug terminal 12 slides from c to d and compresses the elastic member 14; when the male terminal 1 is separated from the female terminal 2, the elastic member 14 drives the plug terminal 12 to slide from d to c to the initial position. Since the elastic member 14 is installed in the slide groove 111 , the slide groove 111 limits the elastic member 14 , thereby preventing the elastic member 14 from being deformed or shifted during the expansion and contraction process, thereby improving the reliability of the elastic member 14 .

[0038] In this embodiment, two inner walls of the male end sheath 11 opposite to each other are provided with a sliding groove 111, and the limiting member 13 is provided along the length direction ( Figure 1 The two opposite ends (in the ab direction) of the male end sheath 11 are respectively slidably disposed in two slide grooves 111. The two inner walls of the male end sheath 11 along the ab direction are both provided with slide grooves 111, so that the two ends of the limiter 13 along the ab direction are respectively slidably disposed in the corresponding slide grooves 111, further improving the stability of the sliding process of the limiter 13. In other embodiments, a slide groove 111 is provided around the inner wall of the male end sheath 11 in the circumferential direction, so that the slide groove 111 is a closed annular groove, and the circumferential edge of the limiter 13 is slidably disposed in the slide groove 111. Alternatively, the slide groove 111 is an unclosed annular groove, and part of the circumferential edge of the limiter 13 is slidably disposed in the slide groove 111.

[0039] like Figure 1 As shown, the elastic member 14 of this embodiment is a spring, which has a low cost and is easy to disassemble. Of course, the elastic member 14 can also be an elastic member such as elastic rubber or shrapnel.

[0040] Optionally, the guide assembly further includes an assembly part 15, which is detachably mounted in the male end sheath 11, and the end of the elastic member 14 away from the limiting member 13 is connected to the assembly part 15. By providing the assembly part 15, the assembly part 15 provides stable support for the elastic member 14. Moreover, the assembly part 15 and the elastic member 14 are assembled into an integral module, which realizes the integrated disassembly and assembly of the assembly part 15 and the elastic member 14, thereby improving the efficiency of disassembly and assembly. When the male end 1 needs to be repaired, it is convenient to remove the limiting member 13 and the assembly part 15 and take out the male end sheath 11, thereby simplifying the maintenance operation of the male end 1. The assembly part 15 of this embodiment is a limiting claw, which is detachably engaged in the positioning groove 112. The assembly part 15 can be provided with a through hole so that the end of the elastic member 14 away from the limiting member 13 is inserted into the through hole. Alternatively, the assembly part 15 is provided with a boss, and the end of the elastic member 14 away from the limiting member 13 is sleeved in the boss. Alternatively, one end of the elastic member 14 away from the limiting member 13 is welded to the assembly member 15. Here, the assembly form of the elastic member 14 and the assembly member 15 is not specifically limited.

[0041] Optionally, the inner wall of the male end sheath 11 of this embodiment is provided with a positioning groove 112, and the assembly part 15 is snapped into the positioning groove 112. The assembly part 15 is snapped into the positioning groove 112, which not only improves the efficiency of assembly and disassembly of the assembly part 15, but also ensures that the assembly part 15 does not occupy the internal space of the male end sheath 11 and does not affect the arrangement of the plug terminal 12. The positioning groove 112 of this embodiment is connected with the slide groove 111. In other embodiments, the assembly part 15 can also be removed, and the inner wall of the male end sheath 11 is provided with a positioning groove 112 connected with the slide groove 111, and the other end of the elastic part 14 away from the limiter 13 is directly installed in the positioning groove 112. Alternatively, the inner wall of the slide groove 111 is provided with a guide column, and the other end of the elastic part 14 away from the limiter 13 is directly mounted on the guide column. By providing the positioning groove 112 or the guide column, the positioning installation of the elastic part 14 in the slide groove 111 is achieved, and the reliability of the elastic part 14 is further improved.

[0042] It should be noted that the limiter 13 is an insulating plastic part and is integrally formed by injection molding to reduce the cost of the limiter 13. Of course, the limiter 13 can also be made of other insulating materials as long as the insulating performance of the limiter 13 is guaranteed.

[0043] Furthermore, the inner wall of the retaining hole 131 is provided with a friction-reducing structure, and the plug terminal 12 slides in engagement with the friction-reducing structure. The provision of the friction-reducing structure reduces the frictional force when the plug terminal 12 slides relative to the retaining hole 131, thereby ensuring smooth insertion of the plug terminal 12 into the receptacle terminal 22 and reducing wear on the plug terminal 12, thereby extending the service life of the plug terminal 12.

[0044] like Figure 2As shown, the friction-reducing structure comprises a plurality of bumps 132, with the plug terminal 12 slidingly engaging with the bumps 132. The provision of the bumps 132 allows the plug terminal 12 to achieve point contact with each bump 132, significantly reducing the contact area between the plug terminal 12 and the limiting hole 131, thereby reducing the frictional force when the plug terminal 12 and the limiting hole 131 slide relative to each other.

[0045] Specifically, the convex hull 132 of this embodiment is a hemispherical convex hull, so that the arc-shaped vertex of the hemispherical convex hull contacts the plug terminal 12, avoiding the convex hull 132 from having sharp corners, and further reducing the wear of the plug terminal 12. Figure 2 As shown, two protrusions 132 are arranged side by side on the inner sidewall of the limiting hole 131 along the cd direction in the figure, so that each inner sidewall of the limiting hole 131 achieves two-point contact with the surface of the plug terminal 12, ensuring stable support for the plug terminal 12. In other embodiments, the sidewall of the limiting hole 131 has three or more protrusions 132 arranged side by side along the cd direction in the figure, so that the inner sidewall of the limiting hole 131 has a wavy surface. Alternatively, the inner wall of the limiting hole 131 is provided with multiple protrusions 132 distributed in a dotted pattern. In other embodiments, the friction-reducing structure can also be a friction-reducing coating, that is, a smooth friction-reducing coating is applied to the inner wall of the limiting hole 131 to reduce friction between the plug terminal 12 and the limiting hole 131. Alternatively, the friction-reducing structure can be a plastic ball rotatably mounted on the inner wall of the limiting hole 131, generating rolling friction between the plug terminal 12 and the plastic ball, thereby reducing friction between the plug terminal 12 and the limiting hole 131.

[0046] like Figure 1 and Figure 3 As shown, the end of the insertion hole 23 is provided with a guide socket 230 for inserting the plug terminal 12. The cross-sectional area of the guide socket 230 gradually decreases along the insertion direction of the plug terminal 12. Specifically, as the plug terminal 12 is inserted from d to c, the cross-sectional area of the guide socket 230 gradually decreases from d to c, forming a flared structure. This allows the guide socket 230 to guide the plug terminal 12 quickly and accurately into the insertion hole 23, ensuring precise mating between the plug terminal 12 and the receptacle terminal 22. Even if the plug terminal 12 is slightly skewed or inserted incorrectly, the guide socket 230 can guide the plug terminal 12 smoothly into the insertion hole 23.

[0047] In this embodiment, the insertion hole 23 is a circular hole, and the guide socket 230 is a bell-shaped opening. The cross-sectional area of the large-diameter end of the bell-shaped opening is smaller than that of the insertion hole 23, while the cross-sectional area of the small-diameter end of the bell-shaped opening is larger than that of the plug terminal 12. By designing the guide socket 230 as a bell-shaped opening, the guide socket 230 has an outwardly inclined arcuate side surface, thereby enhancing the guiding function of the guide socket 230. In other embodiments, the guide socket 230 may also be a tapered opening, i.e., the guide socket 230 has an outwardly inclined tapered surface.

[0048] This embodiment provides a vehicle comprising a wiring harness and the aforementioned wiring harness connector. The wiring harness effectively transmits current and signals between electrical appliances within the vehicle, and the wiring harnesses are connected via the wiring harness connector. The aforementioned vehicle can be a traditional fuel-powered vehicle, a new energy vehicle, or the like, without specific limitation herein. The plug terminals 12 are positioned by a limiting member 13 to maintain a stable spacing between adjacent plug terminals 12, preventing skew and deformation of the plug terminals 12. This improves protection for the plug terminals 12 and enhances the insertion accuracy of the wiring harness connector.

[0049] Furthermore, the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
