[0035] An embodiment of the present application provides a waterproof cover for an electrical connector.

[0036] like Figures 1 to 8 As shown, the electrical connector 10 includes a base 11 and an electrical connector 12 (such as a conductive sheet), the base 11 includes a base 111, at least one socket 112 arranged on a first side of the base 111, and at least one sleeve 113 arranged on a second side of the base 111, the at least one sleeve 113 forms at least one cavity connected to the at least one socket 112, the electrical connector 12 is arranged in the at least one cavity, and the base 111 is provided with a plurality of first mounting holes 114.

[0037] The waterproof cover 20 includes at least one cover body 21, a connecting plate 22, and at least one connecting strap 23. The at least one cover body 21 is adapted to fit over the at least one socket 112 and is used to close or open the at least one socket 112. The connecting plate 22 defines a through hole 221 through which the connecting plate 22 can be inserted into the at least one sleeve 113. The connecting plate 22 also defines a plurality of second mounting holes 222, which are adapted to fit over the plurality of first mounting holes 114. A soft waterproof ring 223 is provided around the periphery of each of the plurality of second mounting holes 222. The waterproof ring 223 can extend into the first mounting hole 114 to abut against the head of the screw 13 in the first mounting hole 114. The at least one connecting strap 23 is a soft connecting strap 23. A first end of the at least one connecting strap 23 is connected to the connecting plate 22, and a second end of the at least one connecting strap 23 is connected to the at least one cover body 21.

[0038] In the embodiment of the present application, the cover 21 of the waterproof cover 20 is used to achieve waterproofing of the socket 112. Specifically, the cover 21 of the waterproof cover 20 can be used to achieve waterproofing of the socket 112 when the socket 112 is not in use. For example, during the transportation or storage of the electrical connector 10, the cover 21 of the waterproof cover 20 can be placed on the socket 112. For another example, when the electrical connector 10 is disconnected from other electrical connectors 10, the cover 21 of the waterproof cover 20 can be placed on the socket 112. When the electrical connector 10 needs to be connected to other electrical connectors 10, the cover 21 of the waterproof cover 20 can be removed from the socket 112. At this time, the electrical connector 10 is in use, and the electrical connector 10 achieves waterproofing through connection with other electrical connectors 10.

[0039] The connecting plate 22 can also be called a mounting plate, and the waterproof cover 20 can be mounted on the electrical connector 10 through the connecting plate 22. Specifically, the through hole 221 of the connecting plate 22 is aligned with the sleeve 113 of the electrical connector 10, and the connecting plate 22 is sleeved on the sleeve 113 of the electrical connector 10.

[0040] The soft connecting strap 23 can be used to carry the cover 21 , so that the waterproof requirement of the electrical connector 10 can be met anytime and anywhere, and it is easy to use.

[0041] For ease of description and understanding, the present embodiment uses an electrical connector 10 with a combined male and female socket as an example. Specifically, two sockets 112 are provided on a first side of a base 111, one of which is a female socket and the other is a male socket. Two sleeves 113 are provided on a second side of the base 111, thereby forming two chambers. One chamber communicates with one of the sockets 112, and the other communicates with the other socket 112.

[0042] Accordingly, there are two covers 21, one cover 21 being adapted to one of the sockets 112 to close or open the socket 112; the other cover 21 being adapted to the other socket 112 to close or open the socket 112. The material of the cover 21 can be a soft material, or a combination of soft and hard materials, that is, the cover 21 can include a soft portion and a hard portion. When there are two covers 21, the materials of the two covers 21 can be the same or different, and the structures of the two covers 21 can be the same or different. They can be reasonably configured according to the structural characteristics and waterproof requirements of the two sockets 112, and this embodiment of the present application does not limit this.

[0043] The number of the first mounting holes 114 and the number of the second mounting holes 222 can be equal. For example, the number of the first mounting holes 114 and the number of the second mounting holes 222 are both four, which are respectively arranged at the four vertex areas of the base 111 and the connecting plate 22. The first mounting holes 114 and the second mounting holes 222 are used to install the screws 13, so as to achieve the connection between the connecting plate 22 and the base 111 through the screws 13. During operation, the screw 13 usually enters from the first mounting hole 114 and passes through the second mounting hole 222. The head of the screw 13 is generally located in the first mounting hole 114, and the screw shaft of the screw 13 is generally located in the second mounting hole 222. Therefore, the aperture of the first mounting hole 114 can be appropriately larger than the aperture of the second mounting hole 222 to better adapt to the shape of the screw 13, thereby improving the stability of the screw 13. In addition, the aperture of the first mounting hole 114 is appropriately larger than the aperture of the second mounting hole 222, and the waterproof ring 223 arranged on the periphery of the second mounting hole 222 can also be extended into the first mounting hole 114, so that the waterproof ring 223 can abut against the head of the screw 13. In this way, the waterproof ring 223 and the head of the screw 13 can be sealed, preventing rainwater from flowing into the gap between the head of the screw 13 and the first mounting hole 114.

[0044] As the name suggests, the waterproof ring 223 is circular (or annular) in shape. It protrudes upward relative to the first surface of the connecting plate 22 (i.e., the surface facing the second side of the base 111). The protruding portion is circular or annular. The waterproof ring 223 can be made of a waterproof material such as rubber or silicone.

[0045] The connecting plate 22 can be made of a hard material, such as plastic, or a soft material, such as rubber.

[0046] In the embodiment of the present application, a soft waterproof ring 223 is provided around the mounting hole of the connecting plate 22. When the connecting plate 22 is connected to the electrical connector 10 via the screws 13, the waterproof ring 223 abuts against the heads of the screws 13, thereby preventing rainwater from flowing in. Thus, the waterproof cover 20 of the embodiment of the present application has a good waterproof effect.

[0047] In some embodiments, the connecting plate 22 and the waterproof ring 223 are integrally formed by an injection molding process.

[0048] To increase the strength of the connecting plate 22 and improve its ease of installation, the connecting plate 22 can be made of a hard material, such as plastic or rubber. Thus, a soft waterproof ring 223 can be formed on the connecting plate 22 through an injection molding process. For example, the connecting plate 22 and the waterproof ring 223 are molded by a secondary injection molding process.

[0049] By adopting the injection molding process to manufacture the connecting plate 22 and the waterproof ring 223 , the structural stability between the connecting plate 22 and the waterproof ring 223 can be improved, so that the waterproof ring 223 has stable waterproof performance.

[0050] In some embodiments, the first surface of the connecting plate 22 is provided with M soft waterproof ribs, and the M waterproof ribs are used to abut against the second side of the base 111. The first surface of the connecting plate 22 is the surface facing the second side of the base 111, and M is an integer greater than 1 or equal to 1.

[0051] By providing waterproof ribs on the first surface of the connecting plate 22 , rainwater can be prevented from flowing into the gap between the connecting plate 22 and the base 11 , thereby achieving a waterproof effect between the connecting plate 22 and the base 11 .

[0052] In some embodiments, the connecting plate 22 and the M waterproof ribs are integrally formed through an injection molding process.

[0053] In some embodiments, the M waterproof ribs include a first waterproof rib 224 and a second waterproof rib 225 , and the second mounting hole 222 is disposed in an area between the first waterproof rib 224 and the second waterproof rib 225 .

[0054] That is to say, waterproof ribs are provided on both sides of the second mounting hole 222 , which can effectively prevent rainwater from flowing into the area where the second mounting hole 222 is located. In this way, the waterproof effect between the connecting plate 22 and the base 11 can be further improved.

[0055] In some embodiments, a soft third waterproof rib 226 is provided on the second surface of the connecting plate 22 . The second surface of the connecting plate 22 is the surface facing away from the second side of the base 111 . N is an integer greater than 1 or equal to 1.

[0056] In one implementation, the electrical connector 10 may further include an encapsulating shell for encapsulating the sleeve 113 and the electrical connector 12. The encapsulating shell may be connected to the connecting plate 22 on its second surface. For example, the base 111, the connecting plate 22, and the encapsulating shell may be connected by screws 13. Thus, by providing waterproof ribs on the second surface of the connecting plate 22, a waterproof effect can be achieved between the connecting plate 22 and the encapsulating shell.

[0057] In some embodiments, the second side of the base 111 is further provided with a flange 111a;

[0058] The third waterproof rib 226 is disposed on the second surface of the connecting plate 22 in an area corresponding to the flange 111 a .

[0059] The area of ​​the second surface of the connecting plate 22 corresponding to the flange 111a can be understood as the edge area of ​​the second surface of the connecting plate 22. By providing the third waterproof rib 226 in the area of ​​the second surface of the connecting plate 22 corresponding to the flange 111a, pressure can be applied to the third waterproof rib 226 by the flange 111a, thereby improving the waterproof effect of the third waterproof rib 226.

[0060] In some embodiments, the connecting plate 22 and the third waterproof rib 226 are integrally formed by an injection molding process.

[0061] In some embodiments, the cover 21 is further formed with a hard operating portion 211. The operating portion 211 facilitates manual operation of the cover 21 when closing or opening the cover 21. For example, the operating portion 211 is a sheet-like structure and may be provided with protrusions or textures to increase the coefficient of friction of the operating portion 211, thereby facilitating manual operation of the cover 21. The operating portion 211 may be located on a side away from the connecting strip 23.

[0062] like Figures 1 to 8 As shown, an embodiment of the present application further provides an electrical connector assembly, comprising:

[0063] The electrical connector 10 includes a base 11 and an electrical connector 12. The base 11 includes a base 111, at least one socket 112 disposed on a first side of the base 111, and at least one sleeve 113 disposed on a second side of the base 111. The at least one sleeve 113 forms at least one cavity communicating with the at least one socket 112. The electrical connector 12 is disposed in the at least one cavity. The base 111 defines a plurality of first mounting holes 114.

[0064] In any of the waterproof covers 20 in the above embodiments, the connecting plate 22 of the waterproof cover 20 is sleeved on at least one sleeve 113 , the connecting plate 22 is connected to the electrical connector 10 via screws 13 , and the waterproof ring 223 of the connecting plate 22 abuts against the head of the screw 13 .

[0065] Any implementation in the above-mentioned embodiment of the waterproof cover 20 can be applied to the embodiment of the electrical connector assembly and can achieve the same beneficial effects. To avoid repetition, it will not be described in detail.

[0066] The above specific embodiments do not constitute a limitation on the scope of protection of this application. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application shall be included within the scope of protection of this application.
