[0036] In the description of this application, it should be noted that, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection, an electrical connection, or a communication connection; it can mean a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood in specific circumstances.

[0037] An embodiment of the present application provides a waterproof cover for an electrical connector.

[0038] 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 has a cavity 13 connected to the outside. At least part of the electrical connector 12 extends into the cavity 13. A soft O-ring 14 is also provided at the bottom of the cavity 13.

[0039] The waterproof cover 20 comprises a flexible cover body 21, a connecting plate 22, and a flexible connecting strap 23. The cover body 21 is formed with a rigid, annular insert 24. The cover body 21 fits over the end 11a of the base 11 to close the chamber 13. When the cover body 21 covers the end 11a of the base 11, the insert 24 is inserted into the chamber 13 and abuts against the O-ring 14 throughout its entire circle. The connecting plate 22 has a through-hole 221 through which it can be fitted onto the base 11. The first end of the connecting strap 23 is connected to the connecting plate 22, and the second end of the connecting strap 23 is connected to the cover body 21.

[0040] The waterproof cover 20 of the embodiment of the present application can be used to waterproof the electrical connector 10 when it is not in use. For example, during transportation or storage of the electrical connector 10, the cover 21 of the waterproof cover 20 can be placed on the base 11 of the electrical connector 10. For another example, when the electrical connector 10 is disconnected from another electrical connector 10, the cover 21 of the waterproof cover 20 can be placed on the base 11 of the electrical connector 10. When the electrical connector 10 needs to be connected to another electrical connector 10, the cover 21 of the waterproof cover 20 can be removed from the base 11 of the electrical connector 10. At this point, the electrical connector 10 is in use, and the electrical connector 10 is waterproofed by being connected to another electrical connector 10. Therefore, the waterproof cover 20 is used quite frequently. To this end, in addition to the cover 21, the waterproof cover 20 may also include a connecting plate 22 and a soft connecting strap 23. The connecting plate 22 can also be called a mounting plate, and the waterproof cover 20 is mounted on the electrical connector 10 via the connecting plate 22. Specifically, align the through hole 221 of the connecting plate 22 with the outer shell 12 of the electrical connector 10, and then fit the connecting plate 22 onto the base 11 of the electrical connector 10. 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 convenient to use.

[0041] In the embodiment of the present application, the cover body 21 is made of a soft material, such as rubber, silicone and other materials. The soft cover body 21 is formed with a hard annular insertion portion 24, and the insertion portion 24 is made of a hard material, such as plastic, plastic and other materials. When the cover body 21 covers the end 11a of the base 11, the cover body 21 and the base 11 interfere (or interference fit) to form a first waterproof structure. When the cover body 21 covers the end 11a of the base 11, the insertion portion 24 is inserted into the chamber 13 and abuts against the O-ring 14 in a full circle to form a second waterproof structure. It can be seen that the cover body 21 and the base 11 in the embodiment of the present application can form two waterproof structures, thereby having a better waterproof effect.

[0042] It should be noted that the shape of the cover 21 is compatible with the shape of the base 11 of the electrical connector 10. If the base 11 is a circular base, the cover 21 is a circular cover; if the base 11 is an irregular base, the cover 21 is an irregular cover. Figures 1 to 8 The base 11 used in the electrical connector 10 shown in FIG. 1 is a circular base.

[0043] In the embodiment of the present application, a hard annular insert 24 is formed on the cover 21. When the cover 21 covers the end 11a of the base 11 of the electrical connector, the insert 24 is inserted into the cavity 13 of the base 11 and abuts the O-ring 14 inside the cavity 13. This creates two waterproof structures: the interference between the cover 21 and the base 11 forms the first waterproof structure, and the interference between the insert 24 and the O-ring 14 forms the second waterproof structure. As can be seen, the waterproof cover of the embodiment of the present application has a good waterproof effect.

[0044] It should be noted that the second waterproof structure formed by squeezing the O-ring 14 through the insertion portion 24 generally has a stronger and more stable waterproof performance than the first waterproof structure, and can meet higher waterproof requirements.

[0045] Furthermore, during the process of putting the cover 21 on the base 11 , since the hard inserting portion 24 can properly fix the shape of the cover 21 , the hard inserting portion 24 can play a guiding role, making it easier for the cover 21 to be put on the base 11 .

[0046] In some embodiments, the cover 21 and the inserting portion 24 are integrally formed by an injection molding process.

[0047] Exemplarily, the cover 21 and the inserting portion 24 are made of soft plastic and hard plastic by secondary injection molding.

[0048] By adopting the injection molding process to manufacture the cover body 21 and the inserting portion 24 , the structural stability can be improved, and the cover body 21 can have stable waterproof performance.

[0049] In some embodiments, the cover 21 includes a cover plate 211 and a flange 212 , and the inserting portion 24 is formed on the inner wall of the cover plate 211 , with a space between the flange 212 and the inserting portion 24 for accommodating the end portion 11 a of the base 11 ;

[0050] When the cover 21 covers the end portion 11 a of the base 11 , the flange 212 is in contact with the outer side wall of the end portion 11 a of the base 11 .

[0051] The flange 212 is soft, and therefore fits against the outer side wall of the end portion 11 a of the base 11 to form a first waterproof structure. Specifically, the flange 212 is interference fit against the outer side of the end portion 11 a of the base 11 .

[0052] In order to enhance the waterproof effect, the inner side wall of the flange 212 may be formed with at least one circle of ridges 212 a to enhance the fit between the flange 212 and the end portion 11 a of the base 11 .

[0053] In some embodiments, the inner sidewall of the chamber 13 is provided with at least one guide groove 112;

[0054] At least one protrusion 241 is provided on the outer wall of the insertion portion 24 . The at least one protrusion 241 is matched with the at least one guide groove 112 . The insertion portion 24 slides along the at least one guide groove 112 to be inserted into the cavity 13 via the at least one protrusion 241 .

[0055] When the cover 21 is required to cover the base 11 , the protrusions 241 of the inserting portion 24 are aligned one by one with the guide grooves 112 , and then the inserting portion 24 is pushed into the cavity 13 along the guide grooves 112 .

[0056] Exemplarily, the number of the protrusions 241 and the number of the guide grooves 112 can be four (or other numbers), and the four protrusions 241 are arranged at intervals along the circumferential direction of the outer side wall of the insertion portion 24 .

[0057] Exemplarily, the protrusion 241 can be provided at an end of the insertion portion 24 away from the cover body 21 , so that when the cover body 21 is covered on the base 11 , the protrusion 241 can be directly aligned with the guide groove 112 , thereby facilitating the insertion of the insertion portion 24 .

[0058] In some embodiments, the inner wall of the chamber 13 is further provided with a locking groove 113 , which is located below the guide groove 112 and communicates with the guide groove 112 ;

[0059] When the insertion portion 24 is inserted into the cavity 13 , at least one protrusion 241 can rotate into the locking groove 113 to lock the insertion portion 24 in a first direction, where the first direction is the depth direction of the cavity 13 .

[0060] By providing the locking groove 113 and rotating the protrusion 241 into the locking groove 113, the insertion portion 24 can be prevented from moving upward and disengaging from the O-ring 14 or reducing the degree of fit with the O-ring 14, so that the insertion portion 24 can be continuously and stably abutted against the O-ring 14, which can improve the waterproof performance stability of the second waterproof structure.

[0061] In some embodiments, the cover 21 is further formed with a hard operating portion 214 , which extends out of the outer wall of the cover 21 .

[0062] The operating portion 214 facilitates manual operation of the cover 21 when closing or opening the cover 21. For example, the operating portion 214 is a sheet-like structure and may be provided with protrusions or textures to increase the friction coefficient of the operating portion 214, thereby facilitating manual operation of the cover 21. The operating portion 214 may be located on a side of the cover 21 away from the connecting strip 23.

[0063] In some embodiments, the connecting strip 23 and the cover 21 are integrally formed.

[0064] By integrally forming the connecting strip 23 and the cover body 21 , the structural stability of the waterproof cover 20 can be further improved, making the waterproof cover 20 more durable.

[0065] In some embodiments, the connecting plate 22 defines a first screw hole 222 , and the connecting plate 22 can be connected to the base 11 through the first screw hole 222 .

[0066] Correspondingly, the base 11 of the electrical connector 10 may also be provided with a corresponding second screw hole 111 , so that the base 11 and the connecting plate 22 can be locked by the screw 15 , thereby enabling the connecting plate 22 to be more stably mounted on the electrical connector 10 .

[0067] like Figures 1 to 8 As shown, an embodiment of the present application further provides an electrical connector assembly, comprising:

[0068] The electrical connector 10 includes a base 11 and an electrical connector 12. The base 11 has a cavity 13 connected to the outside. At least a portion of the electrical connector 12 extends into the cavity 13. A soft O-ring 14 is further provided at the bottom of the cavity 13.

[0069] The waterproof cover 20 and the connecting plate 22 of the waterproof cover 20 are sleeved on the base 11 .

[0070] Any implementation in the above-mentioned waterproof cover embodiment can be applied to the electrical connector assembly embodiment and can achieve the same beneficial effects. To avoid repetition, it will not be described in detail.

[0071] 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.
