[0022] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0023] Ginseng Figure 1-3 As shown, the present invention is an electrical connector assembly that can be used in a high voltage system of a new energy vehicle. The assembly includes an electrical connector 100 and a docking connector 200 that dock with each other. The docking process is first described below. When the electrical connector 100 is ready to be inserted into the docking connector 200 (such as Figure 1As shown in FIG. 2 , the locking device 30 of the electrical connector is located in a substantially vertical position, and slide posts 51 are provided on opposite sides of the outer peripheral surface of the docking connector 200, and the guide opening 312 of the locking device 30 is aligned with the slide post 51. The slide post 51 passes through the guide opening 312 and enters the slide groove 311 of the locking device (as shown in FIG. 2 ). Figure 2 As shown in FIG. 1 , the locking device 30 is rotated backward with force. The shape of the slide groove 311 is designed so that the electrical connector 100 is further inserted into the docking connector 200 during the rotation process of the slide groove 311 and the slide post 51, so that the two are fully matched (as shown in FIG. 1 ). Figure 3 At this time, the locking device 30 is located in a substantially horizontal position, close to the top surface of the body 10 of the electrical connector, and finally the locking device 30 is fixed by the locking member 32 to prevent the locking device from loosening or rotating in the reverse direction (i.e., rotating forward).

[0024] Similarly, when the electrical connector 100 needs to be unplugged, the locking member 32 is pulled backward and the locking device 30 is rotated forward until it abuts against the rib (eg, Figure 2 ), and then pull out the electrical connector 200 with force.

[0025] The detailed structure of the electrical connector 100 is described in detail below. Figure 4-5 As shown, the electrical connector 100 includes a body 10 , a terminal assembly 20 , and a locking device 30 . The locking device 30 is pivotally mounted on the body 10 .

[0026] The body 10 has two terminal holes 11 extending forward, and the terminal assembly 20 is accommodated in the terminal holes 11, and a cable is connected to the rear end thereof. The specific structure of the terminal assembly 20 refers to another patent application filed by the applicant on the same day. The body 10 is provided with a first positioning column 13 and two second positioning columns 14 on its top surface 101. The first positioning column 13 is provided with a positioning groove 131 opening backward, and the second positioning columns 14 are located on both sides of the rear of the first positioning column 13. The lateral width and height of the first positioning column 13 are greater than those of the second positioning columns 14. The body 10 is provided with a strip rib 15 extending in the front-to-back direction and a convex rib 16 located at the front end of the strip rib on its two opposite side surfaces 102. The strip rib 15 has an upper rib surface 151 facing upward, and a first pivoting portion 17, and the first pivoting portion 17 protrudes from the strip rib.

[0027] The locking device 30 includes a rotating member 31 and a locking member 32. The rotating member 31 is provided with a slide groove 311, a guide opening 312 at the front end of the slide groove, and a hanging finger 313, which is used to be matched with the docking connector 200. Figure 6-7, the rotating member 31 is provided with a receiving groove 315, a first through hole 3161 and a second through hole 3162, and the locking member 32 is received in the receiving groove 315. In terms of the overall structure, the rotating member 31 includes two side portions 3181 and a horizontal bar portion 3182 that transversely connects the two side portions. The sliding groove 311, the guide opening 312 and the hanging finger 313 are arranged on the side portion 3181, and the receiving groove 315 and the first and second through holes 3161 and 3162 are arranged on the horizontal bar portion 3182. At the same time, the horizontal bar portion 3182 also serves as an operating portion for the user to apply force. The side portion 3182 is provided with a second pivoting portion 317, which cooperates with the first pivoting portion 17 to enable the rotating member to rotate relative to the body 10.

[0028] The locking member 32 includes an operating portion 321, a first positioning plate 322, a pair of first holding arms 323, and a second holding arm 324 located between the first positioning plate and the first holding arm. The first holding arm 323 is held in the receiving groove 315 to prevent the locking member 32 from falling out of the receiving groove 315. Fig.10 The first latch arm 323 is provided with a laterally protruding latch head 3231, which can latch backwards on the abutment surface in the receiving groove to prevent the latch member 32 from falling off the rotating member 31. In this way, the latch member 32 is always placed on the latch device 30 to avoid the risk of loss. Fig.11 The second buckling arm 324 is provided with a buckle head 3241 protruding downward, which protrudes into the second through hole 3162 by gravity, and is buckled backward on the rear inner wall of the second through hole 3162, which can also prevent the lock member 32 from falling backward from the receiving groove 315, and is also blocked forward by the front inner wall of the second through hole 3162, limiting the lock member 32 from running freely. The operating portion 321 is plate-shaped, which is perpendicular to the first positioning plate and the first and second buckling arms.

[0029] When the rotating member 31 rotates backward to a position close to the top surface 101, Fig.12 As shown, the first positioning column 13 passes through the first through hole 3161 and enters the receiving groove 315, and the locking member 32 moves forward until the first positioning plate 322 is inserted into the positioning groove 131 of the first positioning column 13, thereby preventing the rotating member 32 from rotating forward. At the same time, the second positioning column 14 enters the second through hole 3162, and the second positioning column 14 pushes upward against the second holding arm 324 to move upward and break away from the restriction of the front inner wall of the second through hole 3162, so that the second holding arm 324 can move forward until the buckle head 3241 of the second holding arm 324 is buckled in the receiving groove, thereby locking the locking member to the main body 10. A third through hole is provided behind the second through hole 317 to form a resisting surface 3163, so that the buckle head 3241 can be buckled on the resisting surface 3163. From Fig.12 , 13It can be seen that the first through hole 3161 extends upward through the top surface of the receiving groove 315, which is more conducive to the positioning of the first positioning column 13, and the second through hole 3162 extends to the receiving groove 315. The horizontal bar 3182 is provided with a receiving opening 319 at the corresponding operating part 321 to accommodate the operating part 321. The receiving opening 319 can not only limit the shaking of the operating part, but also help the appearance of the operating part and the rotating part to be more integrated.

[0030] When releasing the lock, a large force is used to move the lock member 32 backward, and the buckle head 3241 of the second buckle arm 324 is separated from the receiving groove 315, and the first positioning plate 322 is also separated from the first positioning column 13. Then the rotating member 31 is rotated forward until the hanging finger 313 abuts against the upper rib surface 151, limiting the rotating member 31 from further rotating forward. At this time, the rotating member 31 is approximately in a vertical state (such as Figure 2 As shown), then the electrical connector 100 can be pulled out. A through slot 3131 is provided between the hanging finger 313 and the rotating member 31, so that the hanging finger 3131 has a certain elasticity.

[0031] The above are only preferred embodiments of the present invention, and should not be used to limit the scope of the present invention. That is, all simple equivalent changes and modifications made according to the claims and the content of the present invention description should still fall within the scope of the present invention.
