Description

Technical Field

[0001] This utility model relates to the field of vehicle accessories, and in particular to a vehicle wiring harness connector. Background Technology

[0002] In the production process of medium and heavy-duty trucks, chassis wiring harnesses are a crucial component. However, due to mechanical movement and environmental factors, chassis wiring harnesses are highly susceptible to damage and corrosion, affecting the normal operation of electrical components and thus posing safety hazards. Furthermore, the high cost and long maintenance cycles of chassis wiring harnesses significantly impact the user experience for medium and heavy-duty truck users.

[0003] Automotive wiring harness connectors are components used for interconnecting and protecting interfaces between automotive wiring harnesses. They can integrate multiple wiring harnesses or cables into one unit, enabling modular production of wiring harnesses and improving circuit maintainability. They can also protect wires, cables, or wiring harnesses from mechanical damage, wear, and bending stress, thereby extending the life of the wiring harness. Furthermore, they can provide insulation to a certain extent, protecting the wires from interference from external electric and electromagnetic fields.

[0004] As more and more wire harnesses are integrated into wire harness connectors, the number of holes and pins on the connectors also increases, resulting in a higher area density. This leads to higher precision requirements when the male and female connectors are mated, which reduces the assembly speed of wire harness mating to some extent. At the same time, the failure rate of mating increases, and the pins are more likely to bend under pressure. Summary of the Invention

[0005] This invention addresses the problem that the increased number of pins in current wire harness connectors leads to higher assembly precision requirements, reduced efficiency, and increased susceptibility to errors. It provides a vehicle wire harness connector with a guiding structure.

[0006] To address the aforementioned problems, this utility model employs a vehicle wiring harness connector, comprising a male plug and a female plug, which are mated together. On the mating surfaces of the male and female plugs, one has a guide post, and the other has a guide groove. The guide post can be inserted into the guide groove. One of the male and female plugs has a locking through hole, and the other has a locking threaded hole. A locking bolt is installed in both the locking through hole and the locking threaded hole. This solution provides a plug-in guiding structure between the male and female plugs. During male-female mating, the insertion of the guide post and guide groove enables rapid and precise mating of the wiring harness connector, thus preventing pin bending. Simultaneously, this design increases the friction and torsional resistance between the connectors. After mating, the bolt locking connection significantly improves the connector's pull-out resistance, enhances connection stability and reliability, effectively reduces the failure rate caused by poor connection, and improves the overall performance of the vehicle's electrical system.

[0007] As a preferred embodiment of a vehicle wiring harness connector, the guide post has a cross-shaped cross-section, and the guide groove is adapted to the shape of the guide post. This cross-shaped design increases guidance and stability during insertion, ensures a smoother connection process, significantly reduces the possibility of installation errors, and improves the connector's compatibility and interchangeability.

[0008] As a preferred implementation of a vehicle wiring harness connector, the guide post has a cross-section comprising a long side and a short side that are perpendicular to each other. The long side is positioned along the width direction of the male connector end face, and the short side is positioned along the length direction of the male connector end face. This design ensures the uniqueness of the wiring harness connector's mating direction, effectively preventing mating failure due to incorrect orientation. Simultaneously, it divides the connector end face into two relatively complete spaces along the length direction, resulting in a more scientific layout that can accommodate more pin holes.

[0009] As a preferred embodiment of a vehicle wiring harness connector, two guide posts are provided, symmetrically arranged on both sides of the locking through hole; two guide grooves are provided, respectively arranged on both sides of the locking threaded hole. This symmetrical design enhances the connector's balance and stability, ensures precise mating, significantly improves the overall strength and durability of the connector, and reduces maintenance frequency.

[0010] As a preferred embodiment of a vehicle wiring harness connector, one of the male and female connectors has a surrounding plate along its outer edge, while the other has a recessed outer edge forming a positioning step. The inner cavity enclosed by the surrounding plate matches the shape of the positioning step. This, combined with guide posts and guide grooves, further forms a multi-layered insertion structure, enhancing the connector's structural strength and resistance to deformation. Simultaneously, the staggered surface of the positioning step from the pin mating surface significantly improves the connector's sealing and dustproof performance, ensuring stability and safety during long-term use.

[0011] As a preferred embodiment of a vehicle wiring harness connector, the male plug has multiple male wire holes along the mating direction, and a male terminal locking hole is provided on the side of the male plug, communicating with the male wire holes. A male terminal locking element is inserted into the male terminal locking hole. The female plug has multiple female wire holes along the mating direction, and a female terminal locking hole is provided on the side of the female plug, communicating with the female wire holes. A female terminal locking element is inserted into the female terminal locking hole. After the cable pins are inserted into the connector, they are fixed by the horizontally inserted locking element, which greatly improves the pull-out resistance of the wiring harness, ensures the firmness of the wiring harness connection, effectively prevents the wiring harness from falling off due to vibration, improves the durability and reliability of the connector, and reduces pin wobble, keeping them in the mating position and making the connector mating easier.

[0012] As a preferred embodiment of a vehicle wiring harness connector, the male terminal locking component includes a connecting plate with a strip on its side. The strip is inserted into the locking hole of the male terminal, and the connecting plate abuts against the side of the male plug. The female terminal locking component has the same structure as the male terminal locking component. This simplifies the connector assembly process, improves production efficiency, reduces manufacturing costs by using the same structure for both the male and female terminals, and ensures the stability and long-term reliability of the connector.

[0013] As a preferred embodiment of a vehicle wiring harness connector, the male plug has male terminal locking holes and male terminal locking elements on both sides; the female plug has female terminal locking holes and female terminal locking elements on both sides. This symmetrical design allows the insert on each side to be shortened by half, making manufacturing and installation easier.

[0014] As a preferred embodiment of a vehicle wiring harness connector, the male plug is provided with a male plug sheath on its outer periphery, and the female plug is provided with a female plug sheath on its outer periphery. The male and female plug sheaths extend towards the opposite side of the mating surfaces of the male and female plugs, respectively. This sheath design effectively protects the internal structure of the wiring harness connector, extends its service life, and improves its aesthetic appearance.

[0015] As a preferred embodiment of a vehicle wiring harness connector, the male plug sheath includes a first housing and a second housing, which are mated together, with the male plug located between the first and second housings; the female plug sheath includes a third housing and a fourth housing, which are mated together, with the female plug located between the third and fourth housings. This facilitates the installation of the plug sheaths.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are as follows: First, by setting up a plug-in guide structure and locking bolts, this solution achieves rapid and precise docking of the wire harness connector, effectively avoiding the problem of pin bending, while significantly improving the connector's pull-out resistance, stability, and reliability, greatly reducing the failure rate caused by poor connection, thereby improving the overall performance of the vehicle's electrical system. Second, the design of the cross-shaped guide post and guide groove enhances the guidance and stability during plugging, greatly reducing the possibility of installation errors and significantly improving the connector's compatibility and interchangeability. In addition, the long and short side design of the guide post ensures the unique docking direction of the wire harness connector, effectively preventing docking failure due to incorrect direction, and optimizing the spatial layout in the length direction, increasing the capacity of pin holes. The symmetrically arranged guide posts and guide grooves further enhance the connector's balance and stability, significantly improving the overall strength and durability of the connector, and reducing maintenance frequency. The design of the surrounding plate and positioning steps forms a multi-layer plugging structure, enhancing structural strength and resistance to deformation, while significantly improving the connector's sealing and dustproof performance, ensuring stability and safety during long-term use. The design of the wire hole and terminal locking mechanism improves the pull-out resistance of the wire harness, ensures the firmness of the connection, effectively prevents the wire harness from falling off due to vibration, and improves the durability and reliability of the connector, while also facilitating connector mating. The simplified design of the terminal locking mechanism improves production efficiency, reduces manufacturing costs, and ensures the stability and long-term reliability of the connector. The symmetrical design of the terminal locking holes and locking mechanism facilitates manufacturing and installation, further improving production efficiency. The sheath design effectively protects the internal structure of the wire harness connector, extends its service life, and improves its aesthetic appearance. Finally, the modular design of the sheath facilitates installation, improving the overall performance and practicality of the connector. Attached Figure Description

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figure 1-3 As shown, a vehicle wiring harness connector includes a male plug 1 and a female plug 2, which are mated together. On the mating surfaces of the male plug 1 and the female plug 2, one is provided with a guide post 3, and the other is provided with a guide groove 4 adapted to the guide post 3. Specifically, the cross-section of the guide post 3 is cross-shaped, including mutually perpendicular long sides and short sides. The mating surfaces of the male plug 1 and the female plug 2 are rectangular. The long side of the cross-section of the guide post 3 is set along the width direction of the end face of the male plug 1, and the short side is set along the length direction of the end face of the male plug 1.

[0025] In addition, one of the male plug 1 and the female plug 2 has a locking through hole, and the other has a locking threaded hole. A locking bolt 5 is installed in both to secure the plugs and prevent them from falling off. Figure 3 As shown, there are two guide posts 3 and two guide grooves 4 respectively. The two guide posts 3 are symmetrically arranged on both sides of the locking through hole, and the two guide grooves 4 are respectively arranged on both sides of the locking threaded hole. Alternatively, it can be understood that the locking through hole is opened in the middle of the guide post 3, thus cutting the guide post 3 into two parts, and the locking threaded hole is located in the middle of the guide groove 4, thus dividing the guide groove 4 into two parts.

[0026] Between the mating end faces of the male plug 1 and the female plug 2, a surrounding plate 6 is provided on the outer edge of one end face, and the outer periphery of the other end face is recessed, with the recessed surface forming a positioning step 7 with the end face. The inner cavity enclosed by the surrounding plate 6 matches the shape of the positioning step 7 to enhance the stability and positioning accuracy of the plug.

[0027] The male plug 1 has multiple male wire holes along the mating direction. A male terminal locking hole 8 is provided on the side of the male plug 1, which communicates with the male wire holes. A male terminal locking element 9 is inserted into the male terminal locking hole 18. Specifically, as shown... Figure 2 As shown, the male terminal holes are arranged in an array, and the male terminal locking holes 8 are located between two adjacent rows of male terminal holes. Each male terminal locking hole 8 communicates with adjacent male terminal holes on both sides. The female plug 2 has multiple female terminal holes along the mating direction, and a female terminal locking hole 10 is provided on its side. The female terminal locking hole 10 communicates with the female terminal holes. The layout of the female terminal holes and the female terminal locking hole 10 is the same as that of the male terminal holes and the male terminal locking hole 8. A female terminal locking member 11 is inserted into the female terminal locking hole 10. The male terminal locking member 9 and the female terminal locking member 11 have the same structure, both including a connecting plate and a strip, as shown... Figure 1 As shown, the connecting plate is attached to the side of the plug (male plug and female plug), and the insert is inserted into the terminal locking hole. The insert can lock the terminals in two adjacent wire holes to achieve fixation.

[0028] Furthermore, both sides of the male plug 1 are provided with male terminal locking holes 8 and male terminal locking elements 9; both sides of the female plug 2 are provided with female terminal locking holes 10 and female terminal locking elements 11. Thus, for the terminal locking elements on each side, the plug strip can be shortened by half, making it easier to manufacture and install.

[0029] To further protect the wire harness connectors, the male plug 1 is provided with a male plug sheath 12 on its outer periphery, and the female plug 2 is provided with a female plug sheath 13 on its outer periphery. Both extend in the direction away from the mating surface of the male plug 1 and the female plug 2, respectively. The male plug sheath 12 includes a first housing and a second housing, which are mated together, and the male plug is located between the first housing and the second housing. The female plug sheath 13 includes a third housing and a fourth housing, which are mated together, and the female plug is located between the third housing and the fourth housing.

[0030] As can be seen from the above embodiments, the beneficial effects of this utility model are that, by adopting a plug-in guide structure and a locking bolt mechanism, this solution achieves rapid and precise docking of the wire harness connector, effectively prevents pin bending damage, significantly enhances the tensile strength, stability and reliability of the connector, greatly reduces faults caused by connection problems, and thus improves the overall performance of the vehicle's electrical system. Next, the design of the cross-shaped guide posts and guide grooves improves guidance and stability during the docking process, significantly reducing the risk of installation errors and greatly improving the compatibility and interchangeability of the connectors. The long and short side design of the guide posts ensures the uniqueness of the connector docking direction, effectively avoiding docking failures caused by incorrect orientation, and optimizes the spatial configuration in the length direction, increasing the number of pin holes. The symmetrical layout of the guide posts and guide grooves further improves the balance and stability of the connector, significantly enhancing overall strength and durability, and reducing the need for maintenance. The combination of the surrounding plate and positioning steps forms a multi-layered plug-in structure, enhancing the structural strength and resistance to deformation, while significantly improving the sealing and dustproof capabilities of the connector, ensuring stability and safety under long-term use. The design of the wire holes and terminal locking components enhances the pull-out resistance of the wire harness, ensuring the stability of the connection, effectively preventing the wire harness from loosening due to vibration, improving the durability and reliability of the connector, and also facilitating the installation of the connector. The simplified design of the terminal locking components improves production efficiency, reduces costs, and ensures the long-term stability and reliability of the connector; the symmetrical design of the terminal locking holes and locking components simplifies the manufacturing and installation process, further improving production efficiency. The sheath design effectively protects the internal structure of the wire harness connector, extends its service life, and enhances its aesthetic appearance; the modular design of the sheath makes installation more convenient, further improving the overall performance and practicality of the connector.
