[0001] The invention relates to the technical field of connectors, and in particular to an electrical connector and an assembly process thereof. Background Art

[0002] The existing electrical connector connection methods basically include the following three categories: 1. Direct plug-in type; 2. Snap-on type; 3. Threaded type. Among them, the direct plug-in connector is fast to plug and unplug and is widely used, but it does not have a locking structure and has low reliability.

[0003] At present, in order to enhance the firmness of the connection, many plug-in electrical connectors generally configure screws between the male and female heads of the connector for connection, such as the connection between a computer host and a display screen, to reinforce the connection to prevent the connector from accidentally falling off and affecting the use of the appliance. This reinforcement method is relatively troublesome. In addition, the plug-in connector needs to ensure that the male and female heads are clean when plugged in. Otherwise, once foreign objects are stuck in the male and female heads, it is easy to cause the connection between the male and female heads to be unstable. However, since one of the male and female heads is generally fixed, it is more troublesome to clean and foreign objects are not easy to remove. There is room for improvement. Summary of the invention

[0055] The transmission mechanism 5 is arranged between the first transmission gear 42 and the opening and closing plate 6, and converts the rotation operation of the control button 3 into the sliding operation of the opening and closing plate 6, thereby enriching the functions of the control button 3;

[0056] The opening and closing plate 6 is provided with a receiving groove on the outer top of the male head 1. The opening and closing plate 6 is slidably connected with the male head 1 and is arranged on the top side of the receiving groove. A scraper 61 for cleaning stains is placed in the receiving groove, which is convenient for storing the scraper 61. The scraper 61 is convenient for cleaning the docking sleeve 11 of the male head 1 and the slot 23 of the female head 2, thereby cooperating with the cleaning mechanism 7 to complete the all-round cleaning of the male head 1 and the female head 2;

[0057] The cleaning mechanism 7 includes a slider 71 and a second scraper 72. The slider 71 is slidably connected to the slide rail 15. The second scraper 72 is fixedly connected to the bottom of the slider 71. The shape of the second scraper 72 is the same as the shape of the gap between the docking sleeve 11 and the inner wall of the male head 1. The docking sleeve 11 is seamlessly plugged into the inner wall of the female head 2.

[0058] Specifically, when the connector is connected, the control button 3 is rotated to control the special-shaped rod 41 to rotate, thereby driving the first transmission gear 42 to rotate, and the first transmission gear 42 drives the transmission mechanism 5 to work, open the opening and closing plate 6, and take out the scraper 61 to pre-clean the slot 23 and the docking sleeve 11. After cleaning, the scraper 61 is put back into the receiving groove. After the internal cleaning of the slot 23 and the docking sleeve 11 is completed, the male head 1 and the female head 2 can be docked. During the plugging process, the plug plate 21 is aligned with the slide rail 15, and the second scraper 72 is inserted as the plug plate 21 slides, and foreign objects are cleaned on the outer wall of the docking sleeve 11 and the inner wall of the male head 1. The first scraper 24 cleans the inner wall of the female head 2 and the outer wall of the slot 23 as the docking sleeve 11 is inserted, and the removed foreign objects are discharged from the bottom of the male head 1 and the female head 2 respectively. It should be noted that during the plugging process, the block 22 and the self-locking mechanism 4 complete self-locking. When the lock needs to be released, press the control button 3.

[0059] Reference Figure 1 , Figure 4 and Figure 8 Specifically, in the embodiment of the present invention, the self-locking mechanism 4 includes a fixed plate 43, a rotating rod 44 and a rotating plate 45. Two fixed plates 43 are provided and are fixedly connected to the inner wall of the male head 1. The rotating plate 45 is arranged between the two fixed plates 43. The rotating rod 44 runs through the rotating plate 45, and both ends of the rotating rod 44 are rotatably connected to the fixed plate 43. A reset spring 46 is fixedly connected between the fixed plate 43 and the rotating plate 45. The reset spring 46 is sleeved on the outside of the rotating rod 44. The reset spring 46 facilitates the resetting of the rotating plate 45. A clamping groove 451 is opened on the rotating plate 45, and the clamping groove 451 is clamped with the clamping block 22. The rotating plate 45 is located on the bottom side of the special-shaped rod 41. The position of the rotating rod 44 is arranged close to the special-shaped rod 41. The force arm distance is adjusted to make it laborious to press and prevent the rotating plate 45 from tilting up at will.

[0060] In the embodiment of the present invention, when self-locking is performed, Figure 4 As shown, one end of the card block 22 has an inclined surface. When plugged in, the rotating plate 45 contacts the inclined surface of the card block 22 to lift the rotating plate 45, and the card block 22 continues to move to the locking groove 451. At this time, the rotating plate 45 loses the support of the card block 22, and the rotating plate 45 falls so that the card block 22 is locked with the locking groove 451. When unlocking is required, the control button 3 is pressed, and the control button 3 drives the special-shaped rod 41 to move downward. The bottom end of the special-shaped rod 41 abuts against the rotating plate 45, and one end of the rotating plate 45 is pressed down. The other end of the rotating plate 45 is tilted, so that the card block 22 is unlocked from the locking groove 451. At this time, you only need to pull out the male head 1 to complete the separation of the male head 1 and the female head 2.
