Abstract
Description
Technical Field
[0001] The invention relates to the technical field of automobile wiring harness connectors, in particular to a novel safety wiring harness connector for electric vehicles. Background Art
[0002] With the continuous development of the automotive field, cars have become the main means of transportation for people; especially new energy electric vehicles, which have developed rapidly in recent years and have become an important trend in the global automotive industry. There are many parts inside new energy electric vehicles, and the internal wiring of the car is relatively complex, especially some important wiring, which has a certain impact on the performance and safety of the car. Therefore, it is very important to install and fix the wiring in the car. Wiring harness connectors are important parts in new energy electric vehicles. Its function is very simple. It builds a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function.
[0003] In order to ensure the stability after plugging in, the existing new wiring harness connectors for electric vehicles usually have a suction cup structure on them, and the suction cup is adsorbed on the outer surface of the socket by the principle of negative pressure adsorption, thereby ensuring the stability of the connector when in use. However, due to some protrusions on the surface of the socket, the suction cup cannot be sealed on the surface of the socket, and a gap will be generated between the suction cup and the socket, so that the sealing cannot be guaranteed, and the stability is still insufficient. Due to some expensive electric vehicles, if the connector falls off, it is easy to cause serious traffic accidents, posing a great safety hazard.
[0004] To this end, we designed a new type of safety wiring harness connector for electric vehicles to solve the above problems. Summary of the invention

By turning on the electric heating wire, the electric heating wire can transfer heat to the plastic seal. Since the plastic seal can be shaped by heat, after the connector body is inserted into the socket, the plastic seal can be abutted against the protrusion on the socket and squeezed into the plastic seal, so that the plastic seal can be sealed against the socket shell, thereby improving the sealing performance and avoiding the problem of air leakage, so as to solve the problems raised in the above-mentioned background technology.

[0008] Further, a pull block is fixedly installed at the end of the pull rod away from the first piston. The diameter of the pull block is larger than that of the pull rod. Anti-slip particles are arranged on the pull block.
[0009] Further, a return spring is fixedly installed between the pull block and the positioning member. The return spring is movably sleeved on the pull rod.
[0010] Further, an air collecting box is fixedly installed at the top of the positioning member. One side of the air collecting box is fixedly inserted with an air guide pipe. The other end of the air guide pipe is fixedly inserted at the top of the positioning member. The second one-way intake valve is located inside the inner circle of the air guide pipe. A sliding member is slidably arranged in the air collecting box. One side of the sliding member is fixedly installed with a second piston which abuts against the inner wall of the air collecting box. Two first sliders are symmetrically and movably arranged in the air collecting box. Two second sliders are symmetrically slidably arranged on one side of the sliding member. A rotating member is rotatably arranged between the first slider and the second slider. An electromagnet is arranged in the air collecting box. The electromagnet is magnetically connected with the sliding member in a matching manner. A connecting pipe is fixedly inserted at the front side of the air collecting box. A solenoid valve is arranged on the connecting pipe. A heat dissipation groove is formed in the limiting frame. A heat dissipation port is formed on one side of the limiting frame. The other end of the connecting pipe is fixedly inserted on one side of the limiting frame and extends into the heat dissipation groove. The heat dissipation groove is communicated with the heat dissipation port. A ventilation hole is formed at the top of the air collecting box. A battery pack is arranged outside the air collecting box. The heat dissipation port is electrically connected with the electromagnet.
[0011] Further, a guide rod is fixedly installed in the air collecting box along the vertical direction. The first slider is slidably sleeved on the guide rod. A chute is formed on one side of the sliding member. A guiding rod is fixedly installed in the chute along the vertical direction. The second slider is slidably sleeved on the guiding rod.
[0012] Further, a mounting seat is fixedly installed on one side of the first slider, a fixed seat is fixedly installed on one side of the second slider, and both ends of the rotating member are rotatably arranged in the mounting seat and the fixed seat respectively.
[0013] Further, a first pin shaft is arranged in the mounting seat, a second pin shaft is arranged in the fixed seat, and both ends of the rotating member are rotatably sleeved on the first pin shaft and the second pin shaft respectively.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By turning on the electric heating wire, the electric heating wire can transfer heat to the plastic seal. Since the plastic seal can be shaped when heated, after the connector body is inserted into the socket, the plastic seal can abut against the protrusions on the socket and be squeezed into the plastic seal, so that the plastic seal can be hermetically abutted against the socket housing, improving the sealing performance and avoiding air leakage problems.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: By pushing and pulling the pull block, the pull block can drive the pull rod and the first piston to reciprocate in the fixed cavity. During this process, the first piston can suck the air between the negative pressure groove, the through port and the socket housing into the fixed cavity through the first one-way intake valve, and then discharge it outside the positioning member through the second one-way intake valve. At this time, negative pressure can be generated in the negative pressure groove, so that the connector body can be stably inserted into the socket, avoiding the problem of poor stability caused by the connector body slipping out of the socket, and having high safety.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The air discharged from the second one-way intake valve will enter the air collecting box through the air guide pipe, so that the air can push the second piston and the sliding member to slide in the air collecting box. During this process, the two second sliders and the first slider move away from each other, causing the rotating member to rotate, so that the air can be received in the air collecting box. Then, by turning on the solenoid valve and the electromagnet, the electromagnet can be energized to adsorb the sliding member, so that the sliding member can squeeze the air and enter the heat dissipation groove through the connecting pipe, and finally discharge it through the heat dissipation port, so that the heat transferred from the plastic seal to the heat dissipation groove can be quickly discharged, accelerating the cooling and shaping of the plastic seal and improving the installation efficiency.

[0023] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "linkage", "setting", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] Please refer to Figures 1-7 , the present invention provides a technical solution: a new type of safety wire harness connector for electric vehicles, including a wire harness main body 1 and a connector main body 2 installed at the end of the wire harness main body 1. A positioning member 3 is fixedly sleeved on the connector main body 2. A limiting frame 4 is fixedly installed on one side of the positioning member 3. A plastic seal 5 is fixedly installed on the inner circle of the limiting frame 4. An electric heating wire 6 is arranged on the plastic seal 5. A negative pressure groove 7 is opened on one side of the positioning member 3. A through hole 8 is opened in the plastic seal 5. The negative pressure groove 7 is communicated with the through hole 8. A fixing cavity 9 is opened in the positioning member 3. A first one-way intake valve 10 is arranged in the fixing cavity 9. A second one-way intake valve 11 is arranged on the top of the positioning member 3. The second one-way intake valve 11, the fixing cavity 9, the first one-way intake valve 10 and the negative pressure groove 7 are all communicated. A gas collecting assembly is also arranged in the fixing cavity 9. The gas collecting assembly includes a first piston 12. The first piston 12 is slidably connected in the fixing cavity 9. One side of the first piston 12 is fixedly installed with a pull rod 13. The other end of the pull rod 13 slidably penetrates through the positioning member 3.
[0025] During specific implementation, the wire harness main body 1 drives the connector main body 2 to be inserted into a matching internal socket of an electric vehicle. In this process, it is necessary to first turn on the electric heating wire 6, so that the electric heating wire 6 transfers heat to the plastic seal 5. Since the plastic seal 5 can be shaped by heat, after the connector main body 2 is inserted into the socket, the plastic seal 5 can abut against the protrusions on the socket and be squeezed into the plastic seal 5, so that the plastic seal 5 can be hermetically abutted against the socket housing. After the plastic seal 5 cools down, it can harden. Then, the operator pushes and pulls the pull rod 13 to drive the first piston 12 to reciprocate in the fixing cavity 9. During this process, the first piston 12 can inhale the air between the negative pressure groove 7, the through hole 8 and the socket housing into the fixing cavity 9 through the first one-way intake valve 10, and then can be discharged outside the positioning member 3 through the second one-way intake valve 11. At this time, negative pressure can be generated in the negative pressure groove 7, so that the connector main body 2 can be stably inserted into the socket, avoiding the problem of poor stability caused by the connector main body 2 slipping out of the socket, and the safety is relatively high.
[0026] Refer to Figures 1-7, a pull block 14 is fixedly installed at one end of the pull rod 13 away from the first piston 12. The diameter of the pull block 14 is larger than that of the pull rod 13, and anti-slip particles 16 are arranged on the pull block 14. By pulling the pull block 14, the pull rod 13 can be driven to move, making it more labor-saving when a person pulls the pull rod 13. By arranging the anti-slip particles 16, the friction between the person's hand and the pull block 14 can be increased, thus helping to solve the problem of slipping when pulling the pull block 14.
[0027] Refer to Figures 1-7 , a return spring 15 is fixedly installed between the pull block 14 and the positioning member 3. The return spring 15 is movably sleeved on the pull rod 13. Pulling the pull block 14 and then releasing it can make the elastic force of the return spring 15 automatically reset the pull block 14, further improving the labor-saving effect.
[0028] Refer to Figures 1-7 , a gas collecting box 17 is fixedly installed at the top of the positioning member 3. One side of the gas collecting box 17 is fixedly inserted with an air guide pipe 18. The other end of the air guide pipe 18 is fixedly inserted at the top of the positioning member 3. The second one-way intake valve 11 is located inside the inner circle of the air guide pipe 18. A sliding member 19 is slidably arranged in the gas collecting box 17. One side of the sliding member 19 is fixedly installed with a second piston 20. The second piston 20 abuts against the inner wall of the gas collecting box 17. Two first sliders 21 are symmetrically and movably arranged in the gas collecting box 17. Two second sliders 22 are symmetrically slidably arranged on one side of the sliding member 19. A rotating member 23 is rotatably arranged between the first slider 21 and the second slider 22. An electromagnet 24 is arranged in the gas collecting box 17. The electromagnet 24 is magnetically connected with the sliding member 19 in a matching manner. A connecting pipe 25 is fixedly inserted at the front side of the gas collecting box 17. An electromagnetic valve 26 is arranged on the connecting pipe 25. A heat dissipation groove 27 is formed in the limiting frame 4. A heat dissipation port 28 is formed in one side of the limiting frame 4. The other end of the connecting pipe 25 is fixedly inserted into one side of the limiting frame 4 and extends into the heat dissipation groove 27. The heat dissipation groove 27 is communicated with the heat dissipation port 28. A ventilation hole 35 is formed in the top of the gas collecting box 17. A battery pack 38 is arranged outside the gas collecting box 17. The heat dissipation port 28 is electrically connected with the electromagnet 24; A guide rod 29 is fixedly installed in the gas collecting box 17 along the vertical direction. The first slider 21 is slidably sleeved on the guide rod 29. A chute 30 is formed in one side of the sliding member 19. A guiding rod 31 is fixedly installed in the chute 30 along the vertical direction. The second slider 22 is slidably sleeved on the guiding rod 31. A mounting seat 32 is fixedly installed on one side of the first slider 21. A fixing seat 33 is fixedly installed on one side of the second slider 22. Two ends of the rotating member 23 are respectively rotatably arranged in the mounting seat 32 and the fixing seat 33. A first pin shaft is arranged in the mounting seat 32. A second pin shaft is arranged in the fixing seat 33. Two ends of the rotating member 23 are respectively rotatably sleeved on the first pin shaft and the second pin shaft.
[0029] During specific implementation, based on the above implementation, the air discharged from the second one-way intake valve 11 will enter the air collection box 17 through the air guide pipe 18, causing the air to push the second piston 20 and the sliding member 19 to slide within the air collection box 17. During this process, the two second sliders 22 will slide along the direction set by the guiding rod 31 within the sliding groove 30 and move away from each other. At the same time, the two first sliders 21 will also slide along the direction set by the guiding rod 29 and move away from each other, causing the rotating member 23 to rotate, allowing air to be collected into the air collection box 17. Then, the electromagnetic valve 26 and the electromagnet 24 are opened, and the electromagnet 24 is energized to adsorb the sliding member 19, causing the sliding member 19 to squeeze the air and enter the heat dissipation groove 27 through the connecting pipe 25, and finally discharged through the heat dissipation port 28. This can quickly discharge the heat transferred to the heat dissipation groove 27 by the plastic seal 5, accelerating the cooling and shaping of the plastic seal 5 and improving the installation efficiency.
[0030] Refer to Figures 1-7 , the two rotating members 23 are cross - arranged, and a pin 34 is inserted at the intersection of the two rotating members 23. This improves the stability of the two rotating members 23 during rotation.
[0031] One side of the positioning member 3 is provided with a threaded port 36, which is communicated with the negative pressure groove 7. A threaded plug 37 is threadedly inserted into the threaded port 36. Unscrewing the threaded plug 37 from the threaded port 36 can allow external air to be injected into the negative pressure groove 7, thus releasing the adsorption of the socket and facilitating the extraction of the connector body 2 from the socket.
[0032] Working principle: When in use, first drive the connector body 2 of the wire harness main body 1 to insert it into a compatible electric vehicle internal socket. During this process, the electric heating wire 6 needs to be turned on first, and the electric heating wire 6 transfers heat to the plastic seal 5. Since the plastic seal 5 can be shaped when heated, after the connector body 2 is inserted into the socket, the plastic seal 5 can abut against the protrusions on the socket and be squeezed into the plastic seal 5, enabling the plastic seal 5 to be in sealed contact with the socket housing. After the plastic seal 5 cools, it hardens. Subsequently, the operator pushes and pulls the pulling block 14, causing the pulling block 14 to drive the pull rod 13 and the first piston 12 to reciprocate within the fixed cavity 9. During this process, the first piston 12 can inhale the air between the negative pressure groove 7, the through - port 8, and the socket housing into the fixed cavity 9 through the first one - way intake valve 10, and then discharge it outside the positioning member 3 through the second one - way intake valve 11. At this time, negative pressure can be generated in the negative pressure groove 7, enabling the connector body 2 to be stably inserted into the socket, avoiding the problem of poor stability caused by the connector body 2 slipping out of the socket, and having high safety.
[0033] It should be noted that during the above operation, the air discharged from the second one-way intake valve 11 will enter the air collection box 17 through the air guide pipe 18, causing the air to push the second piston 20 and the sliding member 19 to slide within the air collection box 17. During this process, the two second sliders 22 will slide along the direction set by the guide rod 31 within the sliding groove 30 and move away from each other. At the same time, the two first sliders 21 will also slide along the direction set by the guide rod 29 and move away from each other, causing the rotating member 23 to rotate, allowing the air to be collected into the air collection box 17. Then, the solenoid valve 26 and the electromagnet 24 are opened, and the electromagnet 24 is energized to adsorb the sliding member 19, causing the sliding member 19 to squeeze the air and enter the heat dissipation groove 27 through the connecting pipe 25, and finally discharged through the heat dissipation port 28. The heat transferred to the heat dissipation groove 27 by the plastic seal 5 can be quickly discharged, accelerating the cooling and shaping of the plastic seal 5 and improving the installation efficiency.

Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above as equivalent embodiments of equivalent changes.
