[0002] Vehicle wiring harness connectors play a vital role in automobiles. They connect key components such as batteries, motors, and controllers to ensure efficient and stable transmission of electricity. In particular, wiring harness connectors are commonly used in new energy vehicles to connect new energy cables. Compared with traditional cables, new energy cables have significant differences in material selection, structural design, and performance requirements. New energy cables are designed to withstand higher voltage and current loads. For example, on-board cables can reach specifications of 600V / 300A, so they are thicker and heavier.

[0003] As the cable becomes thicker and heavier, the car will inevitably experience shaking or severe vibration during driving, which may cause the male and female connectors to become disconnected and separated due to shaking or vibration.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention

[0005] The purpose of the present invention is to design a vehicle wiring harness connector that can ensure that the male connector and the female connector are difficult to be disconnected and separated when the vehicle is shaken or vibrated violently during driving after the weighted cable is connected with the vehicle wiring harness connector, so as to solve the above-mentioned deficiencies in the technology.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The present invention provides Figure 1-4A vehicle wiring harness connector shown in the figure includes a male connector 1 and a female connector 2, the female connector 2 has a groove 3 at the end, a pin 4 is provided in the groove 3, the male connector 1 has a protrusion 5 inserted into the groove 3 at the end, the protrusion 5 has a jack for inserting the pin 4, the female connector 2 is provided with a first parallel slide groove 6 and a second slide groove 7, a negative pressure member 8 is slidably connected in the first slide groove 6, the negative pressure member 8 includes a first slide bar 8a slidably connected to the first slide groove 6, a sealing plate 8b fixedly connected to the end of the first slide bar 8a, a rack 8c fixedly connected to the other end of the first slide bar 8a, and a second exhaust hole 8d provided on the first slide bar 8a, the pin 4 passes through the sealing plate 8b and is slidably connected to the sealing plate 8b, one side of the sealing plate 8b is a negative pressure chamber 9, and the other side is an exhaust chamber 10, the sealing plate 8b and the first slide bar 8a are both hard rubber material components, the pin 4 and the groove The grooves 3 are all interference fit with the sealing plate 8b, the first slide groove 6 is interference fit with the first slide bar 8a, the female joint 2 is provided with a first exhaust hole 11 connected to the exhaust chamber 10, and a toggle member 12 is slidably connected in the second slide groove 7. The toggle member 12 includes a tooth plate 12a slidably connected to the second slide groove 7, and a toggle plate 12b fixedly connected to one end of the tooth plate 12a close to the male joint 1. The toggle plate 12b and the tooth plate 12a are both plastic components. A snap plate 12c is fixedly connected to the side of the toggle plate 12b away from the tooth plate 12a. When the tooth plate 12a is located at the end of the second slide groove 7, the snap plate 12c is snap-connected to the side wall of the female joint 2. A guide groove 14 is also provided in the second slide groove 7. A guide bar 15 fixedly connected to the tooth plate 12a is slidably connected in the guide groove 14. A gear 13 rotatably connected to the female joint 2 is meshed between the rack 8c and the tooth plate 12a. The user holds the male connector 1 with one hand and the female connector 2 with the other hand, and inserts the protrusion 5 into the groove 3. Since there is a gap between the tooth plate 12a and the parallel side wall of the female connector 2, when the protrusion 5 is inserted into the groove 3, the finger generates friction with the outer wall of the female connector 2 and does not push the tooth plate 12a. When the protrusion 5 is inserted into the groove 3, it will come into contact with the sealing plate 8b, gradually pushing the sealing plate 8b into the groove 3, and then the pin 4 will pass through the sealing plate 8b and be inserted into the jack, the sealing plate 8b will push the first slide bar 8a to slide in the first slide groove 6, and the first slide groove 6 will push the rack 8c to move toward the gear 13. When the end of the female connector 2 contacts the male connector 1, the distance between the male connector 1 and the female connector 2 cannot be shortened any further, and the pin 4 is inserted into the jack to complete the electrical connection between the male connector 1 and the female connector 2. At this time, the rack 8c is just meshed with the gear 13; At this time, the user continues to push the dial plate 12b to move toward the side of the male connector 1, and the dial plate 12b drives the tooth plate 12a to move. The guide bar 15 on the tooth plate 12a moves in the guide groove 14 to ensure the moving direction of the tooth plate 12a. The tooth plate 12a drives the gear 13 to rotate, and at the same time drives the buckle plate 12c to move toward the end of the second slide groove 7. The gear 13 drives the rack 8c to move, and the rack 8c drives the first slide bar 8a, and the first slide bar 8a drives the sealing plate 8b to move. At this time, the sealing plate 8b is separated from the protrusion 5, and the sealing plate 8b is separated from the protrusion 5. When the sealing plate 8b moves, the space of the negative pressure chamber 9 gradually increases, so that the air pressure in the negative pressure chamber 9 gradually becomes less than the atmospheric pressure, and the space of the exhaust chamber 10 gradually becomes smaller. When the second exhaust hole 8d on the first slide bar 8a is connected with the first exhaust hole 11, the air in the exhaust chamber 10 is discharged through the first exhaust hole 11 and the second exhaust hole 8d. When the buckle plate 12c is buckled with the female connector 2, the plate 12b is no longer pushed, and the connection between the male connector 1 and the female connector 2 is completed. When the rack 8c moves, the spring 16 is also compressed; When the wiring harness shakes during the movement of the vehicle, causing the male connector 1 and the female connector 2 to have a tendency to separate, since the pressure in the negative pressure chamber 9 is lower than the external atmospheric pressure, the negative pressure chamber 9 will become larger when the male connector 1 is separated from the female connector 2, further reducing the pressure in the negative pressure chamber 9. Therefore, the atmospheric pressure will press the protrusion 5 on the male connector 1 into the groove 3 of the female connector 2, preventing the male connector 1 from separating from the female connector 2. When the male connector 1 needs to be separated from the female connector 2, the user pulls the pull plate 12b to move it away from the male connector 1. Since the snap plate 12c is snap-connected with the female connector 2, the pull plate 12b cannot move. Under normal circumstances, the snap plate 12c needs to be pulled to separate the snap plate 12c from the female connector 2. However, since the pull plate 12b and the tooth plate 12a are both plastic components, the pull plate 12b will be deformed, thereby separating the snap plate 12c from the female connector 2. At this time, continue to pull the paddle plate 12b away from the male connector 1, the paddle plate 12b will drive the toothed plate 12a, the toothed plate 12a will drive the gear 13 to rotate, the gear 13 will drive the rack 8c to move toward the side of the male connector 1, when the toothed plate 12a contacts the end of the second slide groove 7, the toothed plate 12a is separated from the gear 13, and the originally compressed spring 16 begins to reset, the spring 16 will push the rack 8c, the rack 8c pushes the first slide bar 8a, the first slide bar 8a pushes the sealing plate 8b to contact the protrusion 5, at this time, no negative pressure is generated in the negative pressure chamber 9, continue to pull the paddle plate 12b until the paddle plate 12b pulls the female connector 2 to separate from the male connector 1.
