[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-6 A dustproof electrical connector includes a male connector 1 and a female connector 2. The male connector 1 consists of a head 3, a middle part 4 and a tail 5. A first spring 6 is sleeved on the outer wall of the middle part 4. A dust cover 7 is connected to the first spring 6. The dust cover 7 is sleeved on the head 3. A cover plate 8 is rotatably connected to one end of the dust cover 7. One end of the head 3 is provided with a plurality of first jacks 9. One end of the female connector 2 is provided with a second jack 10. A plurality of pins 11 are provided in the second jack 10. The pins 11 are plugged into the first jack 9. The head 3 Inserted in the second socket 10, several balls 12 are movably connected to the outer wall of the female connector 2, and an annular groove 13 is provided on the outer wall of the head 3. One end of several balls 12 are embedded in the annular groove 13, and the other ends of several balls 12 are in contact with the inner wall of the dust cover 7. Several second springs 14 are connected to the second socket 10, and the same first dustproof pad 15 is connected to the several second springs 14. The first dustproof pad 15 is slidably connected in the second socket 10 and is slidably connected to the outer walls of several pins 11.

[0024] Through the cooperation between the first spring 6, the dust cover 7 and the cover plate 8, the dust cover 7 always protects the head 3 of the male connector 1 under the elastic force of the first spring 6, and the rotatable cover plate 8 is able to protect the opening of the dust cover 7 to prevent dust from contacting the head 3 of the male connector 1, and has a certain independent dust-proof effect. Through the cooperation between the second spring 14 and the first dust-proof pad 15, a protection effect is provided for the pin 11 in the female connector 2, and the pin 11 is prevented from contacting dust, and has a certain independent dust-proof effect. Through the cooperation between the ball 12, the annular groove 13 and the inner wall of the dust cover 7, the tightening effect of the male connector 1 and the female connector 2 after plugging is achieved, making the disassembly and assembly between the male connector 1 and the female connector 2 more convenient, and at the same time, the connection part of the male connector 1 and the female connector 2 is protected, and the connection part has a certain dust-proof effect.

[0025] Specifically, in this embodiment, a plurality of axially arranged anti-slip grooves 16 are provided on the outer wall of the dust cover 7 to increase the resistance to manual movement of the dust cover 7 and prevent the dust cover 7 from slipping.

[0026] Specifically, in this embodiment, the dust cover 7 and the cover plate 8 can be hinged by a torsion spring hinge 17, so that the dust cover 7 can be pulled, and the head 3 of the male connector 1 pushes the cover plate 8 to rotate, and when the dust cover 7 is loosened, the first spring 6 is reset, and the head 3 of the male connector 1 is separated from the cover plate 8, thereby realizing automatic closing of the cover plate 8.

[0027] Specifically, in this embodiment, a plurality of ball holes 18 are provided on the outer wall of the female connector 2. The ball holes 18 are located at one end of the outer wall of the female connector 2 and at one end passing through the second insertion hole 10, and the apertures are both smaller than the diameter of the ball 12. This ensures that the inner wall of the dust cover 7 contacts the outer side of the ball 12 while preventing the ball 12 from separating from the outer wall of the female connector 2. It also ensures that the ball 12 contacts the annular groove 13 while preventing the ball 12 from separating from the inner wall of the second insertion hole 10, thereby providing an overall effect.

[0028] Specifically, in this embodiment, the side walls at both ends of the annular groove 13 are inclined surfaces, which are symmetrical with each other and tangent to the outer wall of the ball 12, so that the head 3 of the male connector 1 can drive the ball 12 to expand during the plugging and unplugging process, so that the ball 12 is separated from the annular groove 13, thereby realizing the separation of the male connector 1 and the female connector 2.

[0029] Specifically, in this embodiment, a second dustproof pad 19 is rotatably connected to the first dustproof pad 15. The second dustproof pad 19 is the same as the first dustproof pad 15. The second dustproof pad 19 is arranged on one side of the opening of the second jack 10. When the female connector 2 is plugged in and not in use, the second spring 14 is in a restored state. The first dustproof pad 15 is sleeved on the pin 11. The second dustproof pad 19 can be rotated so that the through hole on the second dustproof pad 19 for the pin 11 to pass through is horizontally misaligned with the through hole on the first dustproof pad 15 for the pin 11, thereby protecting the end of the pin 11 and further improving the dustproof effect.

[0030] Specifically, in this embodiment, a connecting ring 20 is connected to one side of the second dustproof pad 19. The single-sided cross-section of the connecting ring 20 is L-shaped. The connecting ring 20 is rotatably connected to one side of the first dustproof pad 15, thereby realizing the rotatable performance of the second dustproof pad 19 on the first dustproof pad 15 while realizing an integrated design between the second dustproof pad 19 and the first dustproof pad 15.

[0031] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
