A limiting protrusion 3731 is formed on the second surface 373 near one end thereof for engaging with the sidewall of the cover plate 34 for limiting. Limiting protrusion 3731 includes straight line section and circular arc portion connected at straight line portion both ends. When the dust cover 37 is placed on the cover plate 34, the linear portion of the stopper protrusion 3731 abuts against the side wall of the cover plate 34 to be stopped, and the arc portion is received in the first through groove 341. The second surface 373 further protrudes to form two fixing posts 3732 for mounting the pins and fixing one end of the elastic member 36.

The center line of the second surface 373 is provided with a guide groove 3733, and the guide groove 3733 penetrates through the first surface 371 of the dust cover 37 and extends to the side wall of the dust cover 37 close to the limiting protrusion 3731. The guide slots 3733 are positioned to align the guide blocks 331 so that the guide blocks 331 can slide within the guide slots 3733 as the dust cap 37 is moved relative to the cover plate 34 and mounting plate 33.

Two avoiding grooves 3734 are further formed in the second surface 373, the two avoiding grooves 3734 are located on two sides of the guide groove 3733, and each avoiding groove 3734 is adjacent to the corresponding fixing column 3732. The avoiding groove 3734 is used for avoiding the elastic piece 38 when the dust cover 37 moves relative to the cover plate 34 and the mounting plate 33. In this embodiment, the avoiding groove 3734 is a through groove.

One end of each avoiding groove 3734 is provided with a positioning groove 3735, and the positioning groove 3735 does not penetrate through to the first surface 371 and is used for clamping the elastic sheet 38. An inclined surface 3737 is further formed between the avoiding groove 3734 and the positioning groove 3735, that is, the inclined surface 3737 is located at one side of the positioning groove 3735, and the inclined surface 3737 is used for pressing the elastic piece 38 to generate elastic deformation when the dust-proof cover 37 moves to a certain position relative to the cover plate 34.

In a state where the male connector 10 is not inserted into the female connector 30, the male connector 10 and the female connector 30 are both in a state where the dust-proof covers are closed, and dust is prevented from entering, specifically, the dust-proof cover 14 of the male connector 10 covers the end of the male end body 11, and covers the inside, and dust and the like are prevented from entering the male end body 11. The dust cap 37 of the female connector 30 covers the cover plate 34 of the female body 31 and covers the through hole 340 to prevent dust from entering the female body 31.

When the male connector 10 is to be inserted into the female connector 30, the dust cover 37 of the female connector 30 and the dust cover 14 of the male connector 10 are manually opened. The operation of opening the dust cover 37 of the female connector 30 is as follows: the dust cover 37 is pulled to enable the dust cover 37 to move relative to the cover plate 34 and the female end body 31, in the process, the guide block 331 moves in the guide groove 3733, the elastic sheet 38 moves in the avoiding groove 3734 until the elastic sheet 38 abuts against the inclined surface 3737 and generates elastic deformation, and finally slides into the positioning groove 3735, the elastic piece 36 and the shrinkage corrugated tube 35 are in a stretching state and accumulate elastic potential energy, at the moment, although the elastic piece 36 and the shrinkage corrugated tube 35 have elastic force, the elastic sheet 38 is clamped in the positioning groove 3735, and therefore when the force for pulling the dust cover 37 is released, the dust cover 37 can still be positioned and cannot rebound to the original position. The operation of opening the dust cover 14 of the male connector 10 is as follows: when the dust-proof plate 142 of the male connector 10 is pulled, the dust-proof plate 142 is moved to one side of the male end body 11 (the position where the dust-proof plate 142 is pulled out is not limited to the position shown in the figure file in the present embodiment) under the action of the two rotating shafts 15 and the elastic element 14, and the elastic element 14 generates elastic deformation to accumulate elastic potential energy.

After the dust covers of the male plug-in unit 10 and the female plug-in unit 30 are opened, the male plug-in unit 10 is inserted into the female plug-in unit 30, and the sealing ring 17 is also inserted into the female plug-in unit 30, so that a waterproof effect is achieved. When the male connector 10 is fully inserted, the end of the post 18 abuts against the elastic piece 38, and the elastic piece 38 elastically deforms, so that the elastic piece 38 is released from being stuck in the positioning groove 3735.

After the male connector 10 is pulled out from the female connector 30, the dust cap 14 of the male connector 10 rotates relative to the connecting rod 13 under the elastic potential energy of the elastic member 14, and the connecting rod 13 rotates relative to the connecting plate 12, so that the dust cap 14 is automatically covered on the male end body 11. When the male connector 10 is inserted, the push rod 18 presses against the elastic piece 38, and the clamping state between the elastic piece 38 and the dust-proof cover 37 is released, so that after the male connector 10 is pulled out, the dust-proof cover 37 automatically returns to the position under the elastic force of the elastic piece 36 until the limiting protrusion 3731 abuts against the side wall of the cover plate 34.

In the embodiment, after the male plug 10 and the female plug 30 are pulled out from the female plug 30, the dust cover automatically resets, so that the movement of manually covering the dust cover is saved, and the dust is prevented from falling into the dust cover due to forgetting to cover the dust cover. Moreover, the sealing ring 17 can play a waterproof role, so that the dust-proof and automatic resetting effects can be achieved, and the waterproof effect can be achieved.

The waterproof electric connector can be used in different situations, such as plant protection machine industry in unmanned aerial vehicles, agricultural fans, small airplanes, equipment in severe environments with large wind and sand, and the like.

It is understood that various other changes and modifications may be made by those skilled in the art based on the technical idea of the present invention, and all such changes and modifications should fall within the protective scope of the claims of the present invention.
