[0027] See also Figure 1-Figure 5A car wiring harness connector connection structure, comprising a male connector 1, a female connector 2 and a locking module 3, wherein one end of the male connector 1 is connected to the corresponding car wiring harness, and the other end is provided with a plurality of extended connecting pins 11, and the connecting pins 11 are connected to the battery core in the corresponding car wiring harness, one end of the female connector 2 is connected to the corresponding car wiring harness, and the other end is provided with a plurality of connecting sockets 21, the number of the connecting sockets 21 is the same as the number of the connecting pins 11, and a connecting plug 22 is provided in the connecting socket 21, and the connecting plug 22 is also connected to the battery core in the corresponding car wiring harness. The connecting pin 11 can be inserted into the connecting plug 22 to complete the connection of the two automotive wiring harnesses. The male head 1 is provided with a positive magnet unit 12 on the side facing the female head 2, and the female head 2 is provided with a negative magnet unit 23 on the side facing the male head 1. The opposite surfaces of the positive magnet unit 12 and the negative magnet unit 23 have the same magnetic properties and can generate a repulsive thrust to push the male head 1 and the female head 2 apart. The edge of the male head 1 facing the female head 2 is provided with a raised first locking strip 13, and the first locking strip 13 is provided on the upper and lower sides of the male head 1. The female head 2 faces the male head A raised second locking strip 24 is provided at the edge of one side of the head 1, and the second locking strip 24 is provided on the upper and lower sides of the female head 2. The locking module 3 includes a locking buckle 31, and an opening is provided at one end of the locking buckle 31, and a locking groove 32 is provided on the inner side. The shape of the locking groove 32 matches the cross-sectional shape of the male head 1 and the female head 2, so that the locking buckle 31 can be stuck in the position where the male head 1 and the female head 2 are connected. The side wall of the locking groove 32 is provided with a locking hole 33 corresponding to the first locking strip 13 and the second locking strip 24. The locking buckle 31 After being inserted into the connecting position of the male head 1 and the female head 2, the first locking strip 13 and the second locking strip 24 can be inserted into the locking hole 33 of the locking buckle 31 after being fitted together, and the locking buckle 31 can play the role of locking the male head 1 and the female head 2. When the locking buckle 31 is pulled off the male head 1 and the female head 2, under the repulsive force of the positive magnet unit 12 and the negative magnet unit 23, the male head 1 and the female head 2 can be separated to both sides, thereby achieving a quick release effect, which is convenient for emergency power cut-off when an accident occurs, and preventing secondary damages such as short circuit or leakage.

[0028] In order to ensure the stability of the locking buckle 31 in locking the male head 1 and the female head 2, see Figure 5 A locking protrusion 34 protruding inward is provided on the inner side of the opening of the locking buckle 31. Preferably, a quick-release pull ring 36 is provided on the end of the locking buckle 31 away from the opening. Rescuers can pull the quick-release pull ring 36 to quickly separate the locking buckle 31 from the male head 1 and the female head 2.

[0029] In order to ensure that the locking buckle 31 can be removed from the male connector 1 and the female connector 2 smoothly, see Figure 3 and Figure 4The shapes of the first locking strip 13 and the second locking strip 24 both include arc shapes, so that the locking buckle 31 can slide smoothly along the first locking strip 13 and the second locking strip 24.

[0030] In order to ensure the stability of the connection between the male connector 1 and the female connector 2, see Figure 3 and Figure 4 , the male head 1 is provided with a connection groove 14 on the side facing the female head 2, the connection pins 11 are all arranged in the connection groove 14, the female head 2 is provided with a protruding connection platform 25 on the side facing the male head 1, the connection sockets 21 are all arranged on the connection platform 25, the cross-sectional shape of the connection groove 14 matches the shape of the connection platform 25, so as to ensure that the connection platform 25 can be inserted into the connection groove 14, and improve the stability after the male head 1 and the female head 2 are connected. Further, the height of the protrusion of the connection platform 25 is 2-5mm, and the depth of the connection groove 14 is not less than the height of the protrusion of the connection platform 25, so as to ensure that the connection platform 25 can be fully inserted into the connection groove 14, and the 2-5mm protruding height limit can avoid being inserted too deep into the connection groove 14, and prevent it from being unable to pop out of the connection groove 14 during quick release.

[0031] Furthermore, the length of the connecting pin 11 is less than or equal to the depth of the connecting slot 14, thereby preventing the connecting pin 11 from extending out of the connecting slot 14 and preventing the connecting pin 11 from accidentally scratching against debris and being damaged.

[0032] Furthermore, the cross-sectional shapes of the connecting groove 14 and the connecting platform 25 both include isosceles trapezoids. The connecting groove 14 and the connecting platform 25 designed with isosceles trapezoids can play a fool-proof role and prevent the operator from inserting the male connector 1 and the female connector 2 in reverse when connecting them.

[0033] In order to ensure that the male head 1 and the female head 2 can be stably separated in relative directions under the action of repulsion during quick disassembly, the positive magnet unit 12 includes two first magnets 15, which are respectively arranged on the left and right sides of the male head 1, and the reverse magnet unit 23 includes two second magnets 26, which are respectively arranged on the left and right sides of the female head 2. The above design enables the positive magnet unit 12 and the reverse magnet unit 23 to generate repulsion on both the left and right sides of the male head 1 and the female head 2, ensuring that the repulsion can push the male head 1 and the female head 2 apart.

[0034] Furthermore, the positive magnet unit 12 and the negative magnet unit 23 are both made of neodymium magnets. Neodymium magnets are small in size and have strong magnetism, and are suitable for use in automotive wiring harness connectors.

[0035] Preferably, in order to ensure the service life of the automobile wiring harness connector connection structure, the connecting pin 11 and the connecting sleeve 22 are made of pure copper with silver plating. The connecting pin 11 and the connecting sleeve 22 made of the above materials are not prone to generate electric sparks when plugging and unplugging, and are not prone to oxidation loss, thereby reducing the occurrence of poor contact.

[0036] Preferably, the locking module 3 also includes a connecting belt 35, one end of which is connected to the male head 1, and the other end is connected to the female head 2. The setting of the connecting belt 35 can prevent the male head 1 and the female head 2 from bouncing away too far after quick release, and prevent the male head 1 or the female head 2 from contacting other metal parts after separation to cause a short circuit.
