[0052] Technical effects and advantages of the present invention:

[0053] 1. The present invention provides a hook lock assembly. When the female connection terminal and the terminal protective shell are in contact and close to each other, the hook lock assembly drives the rotating frame gear to rotate, thereby driving the locking claw to flip. The locking claw frame and the locking claw are close to the female connection terminal when they are not flipped. After flipping, the locking claw frame and the locking claw will hook the locking slide. The locking slide will compress the top pressure spring and provide elastic force to the locking slide, so that the locking slide will support the locking claw. Therefore, the female connection terminal and the terminal protective shell are more tightly connected and prevented from loosening due to vibration, thereby achieving a better waterproof effect.

[0054] 2. The present invention arranges a connecting rotating frame and a lifting connecting frame. When the connecting rotating frame drives the side connecting frames to move away from each other, the sides of the lifting connecting frames that are close to each other will move toward each other, so that the terminal wiring pushes the male connecting terminal to move, and the connecting terminal on the male connecting terminal side will slowly move from the inside of the terminal protective shell to the outside, and be inserted into the plug-in hole on the female connecting terminal side. In this way, when not in use and not connected, most of the connecting terminals on the male connecting terminal side will be located in the terminal protective shell, thereby achieving a protective effect on the connecting terminals on the male connecting terminal side, which is safer when used.

[0055] 3. The present invention is provided with a accompanying roller, which moves along the inclined surfaces on both sides of the female connecting terminal and rolls, and at the same time the second connecting rod is compressed. As the second connecting rod is compressed to the limit length, the side connecting frame and the supporting rotating frame are driven to achieve the effect of outward expansion, thereby promoting the use of the lifting frame. After the accompanying roller moves to the wheel limiting side plate, the elastic force of the force spring makes the length between the accompanying roller and the side connecting frame recover to the original length, and then the accompanying roller contacts the wheel limiting side plate, and the accompanying roller grabs the two sides of the female connecting terminal, thereby achieving the effect of locking the female connecting terminal and the terminal protective shell.

[0107] See also Figure 1 , Figure 2 , Figure 3 and Fig. 9 As shown, it also includes:

[0108] A male connection terminal 6, which is slidably disposed inside the terminal protection housing 2;

[0109] Terminal connection 601, terminal connection 601 is arranged at one side of the male connection terminal 6;

[0112] The auxiliary spring 603 is fixedly arranged on the end surface of the middle receiving ring 602 , and the auxiliary spring 603 is fixedly arranged on one side of the inner part of the terminal protection housing 2 .

[0113] As the angle of the lifting frame 301 changes, the terminal wiring 601 will slowly move, and the movement of the terminal wiring 601 will push the male connection terminal 6, so that the male connection terminal 6 can continue to be inserted into the plug hole on the side of the female connection terminal 1. At the same time, the telescopic outer tube 604 will become longer, and the auxiliary spring 603 will extend to adapt to the position change of the terminal wiring 601. When the male connection terminal 6 is not in use, part of it will be located inside the terminal protective shell 2, thereby protecting the male connection terminal 6 and preventing the male connection terminal 6 from being exposed to the outside and causing more damage.

[0114] Working principle of the present invention: when using the automobile connector, the male connection terminal 6 needs to be inserted into the plug hole on one side of the female connection terminal 1. At this time, the accompanying roller 405 contacts the inclined surfaces on both sides of the female connection terminal 1, and then pushes the terminal protection shell 2 to move. The accompanying roller 405 will roll during the movement, so that the terminal protection shell 2 can move more smoothly, and at the same time, the male connection terminal 6 will slowly be inserted into the plug hole on one side of the female connection terminal 1, and the length between the two wheel frames 4051 will gradually increase with the movement of the accompanying roller 405, and the force spring 402 will be compressed. When the force spring 402 is compressed to the limit length, the side connecting frames 4 will be forced to move away from each other, thereby driving the supporting rotating frame 3 to expand outward, and then driving the lifting frame 301 to move;

[0115] When the two lifting links 301 move, they will contact the terminal wiring 601, and as the angle of the lifting links 301 changes, the terminal wiring 601 will slowly move. The movement of the terminal wiring 601 will push the male connection terminal 6, so that the male connection terminal 6 can continue to be inserted into the plug hole on one side of the female connection terminal 1. At the same time, the telescopic outer tube 604 will become longer, and the auxiliary spring 603 will be extended to adapt to the position change of the terminal wiring 601. When the male connection terminal 6 is not in use, part of it will be located inside the terminal protection shell 2, so as to protect the male connection terminal 6 and prevent the male connection terminal 6 from being exposed to the outside and causing more damage. Among them, the angle change of the lifting links 301 will drive the waterproof pad 202 to deform. The waterproof pad 202 is made of rubber material, so as to achieve a certain waterproof effect.

[0116] When the male connection terminal 6 is fully inserted into the plug hole on one side of the female connection terminal 1, the accompanying roller 405 will move to one side of the wheel limiting side plate 101. At this time, the second connecting rod 404 will restore its original length to prevent the accompanying roller 405 from falling off, thereby achieving the effect of locking the female connection terminal 1 and the terminal protection shell 2. When unlocking, you only need to pinch the two unlocking connecting plates 5 with your fingers to make the accompanying roller 405 leave the wheel limiting side plate 101 to exit the female connection terminal 1, and at the same time, the angle of the lifting frame 301 will slowly recover, so that the terminal connection 601 can retreat;

[0117] When the female connecting terminal 1 and the terminal protection shell 2 are connected, the power-assisting gear 701 in the hook lock assembly 7 will contact the rotating frame gear 708, and the rotating frame gear 708 will be driven to rotate under the movement of the power-assisting gear 701. The rotation of the rotating frame gear 708 will drive the locking claw frame 705 and the locking claw 706 to flip, and the locking claw 706 will press down the locking slide plate 703. Through the setting of the inclined surface on one side of the top of the locking slide plate 703, the locking slide plate 703 will move, compress the top pressure spring 702, and provide elastic force to the locking slide plate. 703, so that the locking slide plate 703 presses against the locking claw 706, so that the female connection terminal 1 and the terminal protection shell 2 are connected more tightly and prevented from loosening due to vibration, thereby achieving a better waterproof effect, wherein the state of the inclined spring 710 changes to compression release, and changes the tilting direction with the flipping of the locking claw frame 705, thereby preventing the locking claw frame 705 from moving at will, thereby achieving a stable locking effect. When unlocking, move the guide rail 704 to one side, and then move the female connection terminal 1 in the opposite direction.
