Description

Technical Field

[0001] The present invention relates to the technical field of connection and installation of wiring harness connectors for new energy vehicles, and in particular to a wiring harness connector for new energy vehicles. Background Art

[0002] Industrial gateways are widely used in manufacturing, energy, transportation, healthcare, agriculture, and other fields. In the transportation sector, they facilitate the Internet of Vehicles (IoV) and intelligent transportation systems. New energy vehicles (NEVs) in the transportation sector are vehicles that utilize unconventional automotive fuels or novel power units, combined with advanced technologies in vehicle power control and drive, resulting in advanced technical principles, new technologies, and new structures. Unlike traditional fuel vehicles, NEVs are powered by clean energy sources such as electricity and hydrogen, or by novel powertrains. They offer low or zero emissions and are a core focus of the global automotive industry's electrification transformation. The power source of NEVs is a key component that connects the various electrical components of NEVs via wiring harnesses, enabling signal transmission and power connections. Wiring harness connectors, also known as wire connectors, are used to connect two wires and are typically plug-in designs for easy installation and maintenance.

[0003] Because wiring harnesses need to connect multiple power-supplying devices and for ease of operation, wiring harness connectors for new energy vehicles are typically designed with a flat, circular shape. Operators typically manually plug in these connectors. To accommodate the compact interior layout, these connectors are often smaller and feature intricate interface details. Manual plugging requires precise alignment of pins, sockets, or latches within a confined space; even the slightest misalignment can prevent smooth insertion. In densely packed wiring harnesses, where connectors often look similar, it can be difficult to quickly identify their corresponding positions. Repeated attempts not only waste time but can also damage connectors due to incorrect insertion. Furthermore, vehicles experience frequent jolting and vibration during driving, and manual plugging can easily cause connectors to shift if not tightened to the desired level. While the flat, circular design reduces space, the latch or locking mechanism can fail to fully engage due to angle or force issues, leading to the connector gradually loosening, causing power outages, signal loss, and even sparks from poor contact, posing a safety hazard.

DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 8 A wiring harness connector for new energy vehicles comprises a connector body 1, a connector portion 2 fixedly mounted on one side of the connector body 1, a wiring harness tube 3 mounted on one side of the connector portion 2, a connector base 4 fixedly mounted on the connector base 4, and a connector frame 5 fixedly mounted on the connector body 1. The connector frame 5 and the connector body 1 are pluggable with each other, achieving electrical connection through the plug-in design of the wiring harness connector body 1. When the wire bundle in the wiring harness tube 3 passes through the connector portion 2, the pre-installed male / female conductive contacts on its ends form elastic contact with the corresponding contacts in the connector base 4, ensuring a low-impedance conductive path through a multi-point spring structure.

[0035] As a preferred embodiment, please refer to Figures 1 to 4 A wiring harness connector for new energy vehicles also includes: a positioning mechanism 6, which is arranged on the connector frame 5 and the connector body 1. The positioning mechanism 6 includes a sliding piece 10 symmetrically arranged on one side of the connector frame 5, and an arc-shaped plate 12 is fixedly provided at the end of the sliding piece 10. The curvature of the inner wall of the arc-shaped plate 12 is adapted to the curvature of the connector body 1. The positioning mechanism 6 is used to assist in longitudinally positioning the connector body 1 into the connector frame 5;

[0036] In the above embodiment, the curved plate 12, which matches the curvature of the connector body 1, enables floating positioning of the connector body 1 during insertion, thus preventing wear of the male or female conductive contact assembly due to inaccurate positioning during insertion of the connector body 1. The curved plate 12 aligns with the curvature of the connector body 1, forming a guide track for insertion. During the insertion process, even with slight angular deviations, the curved structure automatically guides the male or female contact assembly to the correct position through curved contact, preventing contact displacement caused by hard collisions.

[0037] Specifically, the positioning mechanism 6 also includes a fixed block 7 fixedly mounted on the joint frame 5. The fixed block 7 is symmetrically arranged and has grooves 8 symmetrically formed therein. A fixed rod 9 is fixedly mounted within each groove 8. The outer surface of the fixed rod 9 is slidably connected to a sliding piece 10. The outer surface of the sliding piece 10 slides on the groove wall of the groove 8. The outer surface of the fixed rod 9 is sleeved with a telescopic spring 11. The telescopic spring 11 is located on the side of the sliding piece 10 away from the joint body 1. The positioning mechanism 6 also includes a fixed block 13 symmetrically arranged on the side of the joint body 1 near the connecting portion 2. The side wall of the fixed block 13 is in contact with the sliding piece 10.

[0038] In summary of the above embodiments, when plugging the connector body 1, the operator can pinch the connecting portion 2 and align the connector body 1 with the connector frame 5. At this time, the curved plate 12 will fit on the outer surface of the connector body 1. The curved plate 12 is floated around the connector frame 5 by the telescopic spring 11 on one side of the sliding piece 10. The floating design allows the connector body 1 to produce slight displacement during plugging. The elastic deformation capacity of the curved plate 12 can absorb the lateral force generated by operating errors or vibration. This buffering effect prevents the contact group from being subjected to shear stress due to forced docking, avoiding contact deformation or coating damage.

[0039] As a preferred embodiment, please refer to Figures 1 to 2 as well as Figures 5 to 8 A wiring harness connector for new energy vehicles also includes: a locking mechanism 14, which is arranged on the connecting seat 4 and the connector body 1. The locking mechanism 14 includes a connecting component 15 and a connecting component 25. A limit lock is formed between the square block 19 set in the connecting component 15 and the spherical block 32 set in the connecting component 25. The locking mechanism 14 is used to assist in lateral positioning while locking the connector body 1 and the connector frame 5.

[0040] In the above embodiment, connector assembly 15 and connector assembly 25 enable quick locking between connector body 1 and connector frame 5, preventing vibration during operation from interrupting signal transmission and power connections to electrical components. During insertion, they form a wedge-shaped fit with the inclined guide structure of square block 19. The operator only needs to apply axial thrust to automatically achieve lateral positioning and vertical locking through the mechanical self-locking principle, allowing for a secure connection with a single hand.

[0041] Specifically, connecting assembly 15 also includes connecting blocks 16 symmetrically fixed to connecting base 4. Connecting blocks 16 are located on both sides of joint frame 5. Sliding grooves 17 are defined on connecting block 16. Square grooves 18 are symmetrically defined on connecting block 16. The inner walls of square grooves 18 are slidably connected to square blocks 19, and one side of square blocks 19 is provided with an inclined surface. Sliding grooves 20 are symmetrically defined on connecting block 16. Sliding grooves 20 and square grooves 18 are interconnected. A fixing ring 21 is fixedly defined on the inner walls of sliding grooves 20. A sliding rod 22 is slidably provided through the middle of fixing ring 21. The ends of sliding rod 22 are fixedly connected to square blocks 19. An elastic member 23 is sleeved on the outer surface of sliding rod 22. A fixing ring 24 is fixedly defined on sliding rod 22. The elastic member 23 is located between fixing ring 24 and fixing ring 21.

[0042] Furthermore, the second connecting assembly 25 also includes a second connecting block 26 fixedly mounted on one side of the joint body 1 near the connecting portion 2. The second connecting block 26 is symmetrically arranged and on the same horizontal line as the first connecting block 16. Concentric grooves 27 are formed at both ends of the second connecting block 26. A first movable cavity 28, a second movable cavity 29, and a mounting cavity 30 are sequentially formed on the second connecting block 26 between the concentric grooves 27. A through rod 31 is slidably mounted on the wall of the concentric groove 27. The end of the through rod 31 is fixedly connected to a spherical block 32, which is provided with an adapting groove 33. An elastic member 34 is sleeved on the outer surface of the through rod 31. A sliding block 35 is slidably mounted on the outer surface of the through rod 31. The sliding block 35 is adapted to fit within the adapting groove 33. The elastic member 34 is positioned between the spherical block 32 and the sliding block 35. A limiting ring 36 is fixedly mounted on one side of the sliding block 35 on the through rod 31. The limiting ring 36 and the sliding block 35 are mutually engaged under the restraint of the elastic member 34. A third elastic member 37 is disposed within movable cavity 1 28 and is mounted on through-rod 31. A second limiting ring 38 is fixedly mounted on through-rod 31, with elastic member 37 located on the side of limiting ring 38 near limiting ring 1 36. A cylindrical block 39 is also disposed on the outer surface of through-rod 31 and is fixedly mounted within mounting cavity 30. Limiting ring 38 and cylindrical block 39 are engaged by elastic member 37.

[0043] In summary of the above embodiments, the operator aligns the spherical block 32 on the connecting block 26 with the sliding groove 17 for insertion. Under the limiting action of the limiting ring 28 and the cylindrical block 39, the spherical block 32 and the through rod 31 remain relatively stationary. The spherical surface of the spherical block 32 squeezes the inclined surface of the square block 19 to cause the square block 19 to retract into the square groove 18. The sliding rod 22 slides synchronously in the sliding groove 20. Under the limiting action of the fixing ring 1 21 and the fixing ring 24, the elastic member 1 23 is in a compressed state. When the spherical block 32 is continuously inserted until the spherical block 32 and the square block 19 are out of contact, the horizontal surface of the square block 19 is fitted onto the non-spherical side of the spherical block 32, causing the spherical block 32 to be locked in the sliding groove 1 7, when it is necessary to unlock the connector body 1 and the connector frame 5, the operator presses the end of the through rod 31 away from the spherical block 32 with both hands, causing the elastic member 3 37 to be compressed. At this time, the sliding block 35 gradually approaches and squeezes the square block 19 under the limiting action of the limit ring 1 36, causing the square block 19 to shrink back into the square groove 18 again, and the elastic member 1 23 is compressed. When the inclined surface of the sliding block 35 close to the limit ring 1 36 is on the same horizontal line as the horizontal surface of the square block 19, the connecting part 2 of the connector body 1 is pulled. At this time, the square block 19 squeezes the sliding block 35 to cause the elastic member 2 34 to be compressed, and the inclined surface of the sliding block 35 fits into the adapter groove 33. The connector body 1 and the connector frame 5 are unlocked, and the operator can perform maintenance operations.

[0044] Through all the above embodiments, the working principle of the present invention is specifically as follows:

[0045] The working process of the floating positioning of the positioning mechanism 6: When the operator is plugging in the connector body 1, he can pinch the connecting part 2 and align the connector body 1 with the connector frame 5. At this time, the arc plate 12 will fit on the outer surface of the connector body 1. The arc plate 12 can be floated around the connector frame 5 through the telescopic spring 11 on one side of the sliding piece 10. The floating design allows the connector body 1 to produce a small displacement during plugging. The elastic deformation ability of the arc plate 12 can absorb the lateral force generated by operating errors or vibrations. This buffering effect prevents the contact group from being subjected to shear stress due to forced docking, and avoids contact deformation or coating damage. By matching the arc plate 12 with the curvature of the connector body 1, the floating positioning of the connector body 1 can be achieved during plugging, avoiding wear of the male or female conductive contact group caused by inaccurate position when plugging in the connector body 1. The arc plate 12 fits in with the curvature of the connector body 1 to form a plug-in guide track. During the plugging process, even if there is a slight angle deviation, the arc structure can automatically guide the male or female contact group to slide to the correct position through curved surface contact, avoiding contact deviation caused by hard collision.

[0046] The working process of the locking mechanism 14 locking the joint body 1 and the joint frame 5 is as follows: the operator aligns the spherical block 32 on the connecting block 26 with the sliding groove 17 for insertion. Under the restriction of the limiting ring 2 38 and the column block 39, the spherical block 32 and the through rod 31 remain relatively stationary. The spherical surface of the spherical block 32 squeezes the inclined surface of the square block 19 to cause the square block 19 to retract into the square groove 18. The sliding rod 22 slides synchronously in the sliding groove 20. Under the limiting effect of the second 24, the elastic member 1 23 is now in a compressed state. When the spherical block 32 is continuously inserted until the spherical block 32 and the square block 19 are disengaged, the horizontal surface of the square block 19 fits against the non-spherical side of the spherical block 32, causing the spherical block 32 to be locked in the sliding groove 17. The connector body 1 and the connector frame 5 are quickly locked through the connecting component 15 and the connecting component 2 25, preventing the signal transmission and power connection of the electrical components from being interrupted due to vibration during driving. During the plug-in process, a wedge-shaped fit is formed with the inclined guide structure of the square block 19. The operator only needs to apply axial thrust to complete the lateral positioning and vertical locking through the automatic self-locking of the locking mechanism 14, and a reliable connection can be completed with a single hand.

[0047] The working process of the locking mechanism 14 unlocking the connector body 1 and the connector frame 5 is as follows: when the connector body 1 and the connector frame 5 need to be unlocked, the operator presses the end of the through rod 31 away from the spherical block 32 with both hands, causing the elastic member 3 37 to be compressed. At this time, the sliding block 35 gradually approaches and squeezes the square block 19 under the restriction of the limit ring 1 36, causing the square block 19 to shrink back into the square groove 18 again, and the elastic member 1 23 is compressed. When the inclined surface of the sliding block 35 close to the limit ring 1 36 is on the same horizontal line as the horizontal surface of the square block 19, the connecting portion 2 of the connector body 1 is pulled. At this time, the square block 19 squeezes the sliding block 35, causing the elastic member 2 34 to be compressed, and the inclined surface of the sliding block 35 fits into the adapter groove 33. The connector body 1 and the connector frame 5 are unlocked, and the operator can perform maintenance operations. This eliminates the tedious steps of manually resetting the traditional locking mechanism 14, shortens the maintenance cycle, and improves maintenance efficiency.

[0048] It should be understood by those skilled in the art that the discussion of any of the above embodiments is merely illustrative, and within the scope of the present invention, the technical features of the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
