[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 As shown:

[0023] A dustproof electronic connector includes a female connector 1 and a male connector 2 for plugging into the female connector 1. The male connector 2 is provided with a pin header 4. The surface of the female connector 1 is provided with a pinhole 3 adapted to the pin header 4.

[0024] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "most of the existing electronic connectors include a male head and a female head, and the female connector is provided with many pinholes 3 exposed to the air, which easily causes the accumulation of internal dust, and easily causes poor connection between the pin header 4 and the female connector, affecting the normal operation of the circuit and reducing the use effect of the connector." In terms of use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve this technical problem, a dustproof component 5 is added to the application document.

[0025] More specifically:

[0026] like Figure 1-Figure 4 As shown:

[0027] A dustproof assembly 5 is mounted on the female connector 1. The dustproof assembly 5 comprises a strip-shaped blocking plate 503 disposed on the surface of the female connector 1 near each longitudinal row of pinholes 3, a symmetrically arranged rectangular groove 502 formed on the surface of the female connector 1, and rectangular frame plates 506 that slide within the rectangular grooves 502 formed on the female connector 1. The ends of the strip-shaped blocking plate 503 are fixedly connected to the two sets of rectangular frame plates 506.

[0028] A symmetrically arranged telescopic rod 507 is fixed between the rectangular frame plate 506 and the female connecting joint 1, and a spring 508 is wound around the surface of the telescopic rod 507;

[0029] A limit rod 504 is fixed inside the rectangular frame plate 506, and a top sheet 501 that can be plugged into the rectangular frame plate 506 is installed inside the male connector 2. One end of the top sheet 501 is provided with an inclined chamfer.

[0030] The bottom end of the rectangular frame plate 506 and the side close to the top plate 501 are both designed as open structures, and the two ends of the spring 508 are fixedly connected to the female connecting joint 1 and the rectangular frame plate 506 respectively.

[0031] In this embodiment, when the dustproof electronic connector is in use, when the pin header 4 on the male connector 2 is inserted into the pinhole 3 on the female connector 1, the top plate 501 first contacts the limit rod 504. As the male connector 2 is continuously pushed, the limit rod 504 slides on the inclined surface of the chamfered portion of the top plate 501.

[0032] As the top plate 501 moves on the inclined surface, its height increases, thereby pushing up the rectangular frame plate 506 and compressing the telescopic rod 507 and the spring 508. As the rectangular frame plate 506 moves upward, it also drives the strip-shaped blocking plate 503 to move upward.

[0033] When the inclined surface of the top sheet 501 is fully inserted into the rectangular frame plate 506, the limiting rod 504 is located on the horizontal surface of the top sheet 501. At this time, the strip-shaped blocking sheet 503 is misaligned with the vertical row of pinholes 3 of the female connector 1, releasing the blockage of the pinholes 3. At the same time, one end of the pin 4 is located at the end of the pinhole 3. Then, the male connector 2 is plugged into the female connector 1.

[0034] When the male connector 2 is detached from the female connector 1, the pin header 4 is pulled out of the pinhole 3, and the top plate 501 is pulled out of the rectangular frame plate 506. At this time, the spring 508 rebounds, thereby driving the rectangular frame plate 506 to reset, and the rectangular frame plate 506 drives the strip blocking plate 503 to reset, so that the pinhole 3 is blocked by the strip blocking plate 503. Through this operation, the female connector 1 can be prevented from being exposed to the outside for a long time, which may cause dust to enter the inside of the pinhole 3, effectively blocking the accumulation of dust inside the pinhole 3, and avoiding the pin header 4 on the male connector 2 from being inserted into the pinhole 3 of the female connector 1 to cause poor contact problems, which can better ensure the normal operation of the circuit and improve the use effect of the electronic connector.

[0035] Going further;

[0036] In an optional embodiment, the portion of the top sheet 501 that extends relative to the pin header 4 is an inclined chamfered portion;

[0037] The height of the inclined chamfered portion of the top sheet 501 is greater than the inner diameter of the needle hole 3 .

[0038] In this embodiment, when the chamfered portion of the top sheet 501 is fully inserted into the rectangular frame plate 506, the pin header 4 and the pinhole 3 are still in a separated state. The height of the chamfered portion of the top sheet 501 is greater than the inner diameter of the pinhole 3. During this process, the rectangular frame plate 506 drives the strip-shaped blocking sheet 503 to completely release the blockage of the pinhole 3, thereby not affecting the insertion of the pin header 4 into the pinhole 3.

[0039] Going further;

[0040] In an optional embodiment, a sleeve 505 is sleeved on the surface of the limiting rod 504 , and the sleeve 505 can reduce the friction between the limiting rod 504 and the top sheet 501 .

[0041] In this embodiment, the provision of the sleeve 505 can reduce the friction between the limiting rod 504 and the top sheet 501, thereby improving the smoothness of the insertion of the top sheet 501.

[0042] When the pins 4 on the male connector 2 are inserted into the pinholes 3 on the female connector 1, the top plate 501 first contacts the limiting rod 504. As the male connector 2 is continuously pushed to move, the limiting rod 504 slides on the inclined surface of the inclined chamfered part of the top plate 501. The setting of the sleeve 505 can reduce the friction between the limiting rod 504 and the top plate 501, thereby improving the smoothness of the insertion of the top plate 501. As the inclined surface of the top plate 501 moves, the height continues to increase, thereby pushing the rectangular frame plate 506 upward, and compressing the telescopic rod 507 and the spring 508. As the rectangular frame plate 506 moves upward, it drives the strip blocking plate 503 to move upward. When the inclined surface of the top plate 501 is completely inserted into the interior of the rectangular frame plate 506, the limiting rod 504 and the sleeve 505 are located on the horizontal surface of the top plate 501. When the pinhole 3 is pulled out of the pinhole 3, the pin 4 on the male connector 2 is pulled out of the pinhole 3, and the top plate 501 is pulled out of the rectangular frame plate 506. At this time, the spring 508 rebounds, thereby driving the rectangular frame plate 506 to reset, and the rectangular frame plate 506 drives the strip blocking plate 503 to reset, thereby blocking the pinhole 3 through the strip blocking plate 503. Through this operation, the female connector 1 can be prevented from being exposed to the outside for a long time, which may cause dust to enter the inside of the pinhole 3, effectively blocking the accumulation of dust inside the pinhole 3, and preventing the pinhole 4 on the male connector 2 from being inserted into the pinhole 3 of the female connector 1 to cause poor contact, which can better ensure the normal operation of the circuit and improve the use effect of the electronic connector.
