Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] Please see Figure 1-7In this embodiment of the present invention, a waterproof USB connector includes a connector body 100, an outer shell 200, a movable sleeve 300, and a protective cover 400. The outer shell 200 has a through-hole inside, mainly for fitting with the outer shell of the connector body 100. The inner wall of the outer shell 200 is provided with an anti-slip pad to enhance the friction between the outer shell 200 and the connector body 100, ensuring the outer shell 200 fits tightly against the outer shell of the connector body 100. The top of connector 100 has a sliding slot 210, and the movable sleeve 300 is also rectangular in shape. The size of the movable sleeve 300 is larger than the size of the connector body 100. The movable sleeve 300 covers the outer periphery of the connector body 100 connector. The bottom of the movable sleeve 300 is slidably inserted into the sliding slot 210. A limit ring 320 is fixedly connected to the bottom surface of the movable sleeve 300. The limit ring 320 is used to prevent the movable sleeve 300 from coming out of the insertion groove 230. Several compression springs 330 are fixedly connected to the bottom surface of the limit ring 320. The other end of the compression spring 330 is fixedly connected to the inner bottom surface of the sliding slot 210, so that in the absence of external force, the compression spring 330 will push the moving sleeve 300 upward, so that the moving sleeve 300 is defaulted to covering the outside of the connector body 100 connector. The top surface of the moving sleeve 300 is provided with a sealing ring 310, which is made of highly elastic silicone material. The width of the sealing ring 310 is greater than the width between the two inner walls of the insertion slot 230, so that when the connector body 100 is inserted, the sealing ring 310 can seal the moving sleeve 300. The protective cover 400 is also rectangular, with a small gap between the 00 and the insertion slot 230. The size of the protective cover 400 is larger than that of the movable sleeve 300, so that the protective cover 400 can be used to cover the joint of the movable sleeve 300 and the connector body 100. The protective cover 400 is rotatably connected to the outer wall of the outer shell 200 through two connecting rods 440. The top surface of the outer shell 200 is provided with an insertion slot 230, the size of which matches the size of the protective cover 400. The bottom end of the protective cover 400 is inserted into the insertion slot 230.

[0030] Specifically, during installation, the connector body 100 can be passed through the outer casing 200 from top to bottom, so that the outer casing of the connector body 100 is locked against the inner wall of the outer casing 200. The sealing ring 310 is flush with the top of the connector body 100 connector. The anti-slip rubber pad on the inner wall of the outer casing 200 enhances the sealing performance. During use, the connector body 100 connector is aligned with the socket interface and inserted. As the connector body 100 connector is inserted into the socket, the sealing ring 310 is compressed by the socket surface, thereby causing the moving sleeve 300 to retract into the insertion groove 230. The compression spring 330 is compressed until the connector body 100 connector is fully inserted into the socket. At this time, the bottom surface of the sealing ring 310 abuts against the top surface of the outer casing 200, and its top surface abuts against the outer wall of the socket, thus achieving a seal. When the connector body 100 is no longer needed, the connector body 100 is pulled out, and the compression spring 330, which has lost pressure, returns to its initial state, causing the moving sleeve 300 to return to its original position. At this time, the connecting rod 440 is rotated to adjust the position of the protective cover 400, so that the protective cover 400 covers the outside of the moving sleeve 300, and the bottom end of the protective cover 400 is inserted into the insertion groove 230. The sealing ring 310 abuts against the inner top surface of the protective cover 400, so that the connector of the connector body 100 is sealed inside, preventing dust and moisture from entering.

[0031] like Figure 4 and Figure 7 As shown, in this embodiment, the outer cover 200 has two opposite sidewalls with sliding grooves 220, and the protective cover 400 has two opposite sidewalls with connecting posts 410 fixedly connected. The outer ends of the two connecting posts 410 are rotatably connected to one end of the two connecting rods 440, and the other ends of the two connecting rods 440 are rotatably connected to connecting posts 430. The opposite ends of the two connecting posts 430 are fixedly connected to sliders 420, and the two sliders 420 are slidably connected to the two sliding grooves 220 respectively.

[0032] In this embodiment, when it is necessary to open the protective cover 400, pull the protective cover 400 upward, and the slider 420 moves along the slide groove 220, so that the protective cover 400 is disengaged from the moving sleeve 300. Then rotate the connecting rod 440 so that the connecting rod 440 and the connecting post 430 rotate together, so that the connecting rod 440 drives the protective cover 400 to deflect and is no longer on the same horizontal line as the moving sleeve 300. At this time, the connector body 100 can be inserted and used.

[0033] like Figure 2 and Figure 7 As shown, in this embodiment, a wire clamping ring 450 is fixedly connected to the outer wall of the protective cover 400. The wire clamping ring 450 has a certain degree of flexibility and is provided with an opening.

[0034] In practice, when the connector body 100 is plugged into the socket, the connecting rod 440 is rotated around the connecting post 430 as the axis, causing the protective cover 400 to deflect. This causes the side of the protective cover 400 with the wire clamping ring 450 to move closer to the position of the wire on the connector body 100, and the connecting post 410 and the connecting rod 440 to rotate relative to each other, so that the protective cover 400 is horizontal with the wire and the wire is clamped in the wire clamping ring 450, thus temporarily fixing the protective cover 400 to the connector body 100.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
