[0002] As an electrical product, miniature sockets have different requirements in different usage environments. In some cases, they need to be waterproof while in use, while in others they only need to be waterproof when not in use.

[0003] Currently, there are various waterproof structures available on the market for small sockets when they are not in use. Therefore, how to break through the existing waterproof structures and improve the waterproof rating has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is how to improve the protective effect of a small socket. A small socket includes:

[0005] The housing contains a socket module. The top surface of the housing has a protrusion, and a sealing gasket is fixed to the top surface of the protrusion. The socket hole of the socket module is located on the top surface of the protrusion. The sealing gasket and the socket hole are independent of each other.

[0006] The flip cover has one end rotatably connected to the housing and the other end snapped to the housing. The flip cover has a groove and a limiting protrusion on the side facing the housing. The groove engages with the top surface of the sealing gasket, and the limiting protrusion abuts against the side of the sealing gasket near the center of the protrusion.

[0007] The groove is a stepped groove, which includes a first groove and a second groove. The first groove is connected to the second groove. The limiting protrusion is located on one side of the second groove. The depth of the second groove is greater than the depth of the first groove.

[0008] One of the housing and the flip cover is provided with a snap-fit ​​protrusion, and the other of the housing and the flip cover is provided with a snap-fit ​​groove that engages with the snap-fit ​​protrusion.

[0009] The snap-fit ​​protrusion is provided on the flip cover, and the flip cover is also provided with a driving part, which drives the snap-fit ​​protrusion to move.

[0010] An elastic element is also provided at the rotatable connection between the housing and the flip cover, and the elastic element drives the flip cover to rotate.

[0011] The socket module includes a terminal block, and the housing is provided with a fixing hole and a wire hole. The fixing hole and the wire hole cooperate with the terminal block. The side wall of the fixing hole is provided with an anti-detachment limiting part, which prevents the bolt of the terminal block from falling off.

[0012] It also includes an indicator light. The housing includes a base and a top cover. The base and the top cover cooperate to form a first receiving cavity. The socket module is housed in the first receiving cavity. The socket module includes a conductive sheet. The indicator light is electrically connected to the conductive sheet.

[0015] The type of socket is two-hole, three-hole, five-hole, or small five-hole.

[0016] The technical solution of this utility model has the following advantages:

[0017] 1. The present invention provides a small socket. With this structure, when not in use, the flip cover can be rotated to achieve a fastening with the housing. At this time, the sealing gasket is located between the flip cover and the boss, and the limiting protrusion is located on the inner side, forming a double sealing effect and improving the waterproof sealing level.

[0018] 2. The present invention provides a small socket with a stepped groove that creates a multi-compression effect.

[0039] Example 1

[0040] This embodiment provides a small socket, as shown in the attached diagram. Figures 1-7 As shown, it includes:

[0041] The housing 11 houses the socket module 12. A boss 111 is located on the top surface of the housing 11, and the socket 121 of the socket module 12 is situated on the top surface of the boss 111. The plug of an external power supply device can mate with the socket 121 to form an electrical connection. A sealing gasket 13 is fixed to the top surface of the boss 111. The sealing gasket 13 and the socket 121 are independent and do not interfere with each other. Specifically, when the plug of an external power supply device mates with the socket 121, the sealing gasket 13 will not interfere with insertion or removal. The function of the sealing gasket 13 is to provide a sealing effect.

[0042] The flip cover 14 is rotatably connected to the housing 11 at one end and snap-fitted to the housing 11 at the other end. When the flip cover 14 is snap-fitted to the housing 11, the flip cover 14 closes the socket 121 (the plug of the external power supply device cannot be matched with the socket 121); when the snap-fit ​​connection between the flip cover 14 and the housing 11 is released, the flip cover 14 can be rotated and the plug of the external power supply device can be matched with the socket 121.

[0043] The flip cover 14 has a groove 141 and a limiting protrusion 142 on the side facing the housing 11. Specifically, the bottom surface of the flip cover 14 has the groove 141 and the limiting protrusion 142. The groove 141 mates with the top surface of the sealing gasket 13, meaning the shape of the sealing gasket 13 matches the shape of the groove 141. The limiting protrusion 142 abuts against the center of the sealing gasket 13 near the boss portion 111, and also abuts against the inner side of the sealing gasket 13. With this structure, when not in use, rotating the flip cover 14 achieves a locking mechanism with the housing 11. At this time, the sealing gasket 13 is located between the flip cover 14 and the boss portion 111, and the limiting protrusion 142 is located on the inner side, forming a double sealing effect and improving the waterproof sealing level.

[0044] Specifically, as shown in the attached document Figures 1-7 As shown, the groove 141 is a stepped groove, including a first groove 1411 and a second groove 1412. The first groove 1411 and the second groove 1412 are connected. The limiting protrusion 142 is located on one side of the second groove 1412. The depth of the second groove 1412 is greater than the depth of the first groove 1411, specifically the distance extending to the top surface of the flip cover 14. The stepped groove design of the groove 141 creates a multi-compression effect. The portion of the sealing gasket 13 located in the first groove 1411 forms a preliminary waterproof seal. The portion of the sealing gasket 13 located in the second groove 1412 deforms due to compression, and the excess portion enters the second groove 1412, forming multiple compressions and improving the sealing effect. Alternatively, the sealing effect can also be improved by designing the sealing gasket 13 as a stepped structure.

[0045] Specifically, one of the housing 11 and the flip cover 14 is provided with a snap-fit ​​protrusion 15, and the other of the housing 11 and the flip cover 14 is provided with a snap-fit ​​groove 16 that mates with the snap-fit ​​protrusion 15. The groove 141 is a stepped groove, and the snap-fit ​​protrusion 15 and the snap-fit ​​groove 16 mate to form a snap-fit ​​connection and fixation effect.

[0046] Specifically, a snap-fit ​​protrusion 15 is disposed on the flip cover 14, and the flip cover 14 is also provided with a driving part 143, which drives the snap-fit ​​protrusion 15 to move. The driving part 143 realizes the action of the snap-fit ​​protrusion 15, thus better achieving the snap-fit ​​connection and release. In this embodiment, the driving part 143 and the snap-fit ​​protrusion 15 are arranged vertically, and their connection point is connected to the rest of the flip cover 14 through a connecting part 144, forming the driving effect of the driving part 143. In addition, the driving part 143 can also be provided with wear-resistant ribs to improve the driving effect.

[0047] Specifically, as shown in the attached document Figure 6 As shown, an elastic element 17 is also provided at the rotatable connection between the housing 11 and the flip cover 14. The elastic element 17 drives the flip cover 14 to rotate. The function of the elastic element 17 is to drive the flip cover 14 to rotate quickly, that is, when the snap connection is released, the flip cover 14 can be opened quickly. The rotatable connection is specifically formed by the cooperation of a rotating shaft and a hole. In this embodiment, the elastic element 17 is specifically a torsion spring. When the flip cover 14 rotates, the torsion spring stores energy. When the snap connection is released, the torsion spring quickly releases energy, driving the flip cover 14 to rotate quickly.

[0048] Specifically, the sealing gasket 13 is annular, which can be a circular ring or other annular shapes. The sealing gasket 13 can be fixed to the top cover by adhesive bonding or by secondary injection molding. In this embodiment, the groove 141 is also an annular groove with a stepped cross-section. The limiting protrusion 142 is also annular. Alternatively, it can be a square ring structure.

[0049] Specifically, when the groove 141 is an annular groove, a reinforcing rib 1413 is also provided in the second groove 1412. The reinforcing rib 1413 connects the two side walls of the second groove 1412 to improve the strength of the flip cover 14.

[0050] Specifically, as shown in the attached document Figures 4-5As shown, the socket module 12 includes a terminal block 18 for connecting to conductive components (such as wires or conductive sheets) of an external circuit. The terminal block 18 is then tightened with bolts to achieve an electrical connection. The housing 11 has a fixing hole 112 and a wire-passing hole 113. The fixing hole 112 and the wire-passing hole 113 mate with the terminal block 18. For example, an external wire passes through the wire-passing hole 113 and extends into the terminal block 18. A screwdriver passes through the fixing hole 112, causing the bolt to move and tighten the external wire. The central axis of the fixing hole 112 and the central axis of the wire-passing hole 113 can be perpendicular or inclined. The side wall of the fixing hole 112 has an anti-detachment limiting part 1121 to prevent the bolts of the terminal block 18 from falling off. The anti-loosening limiting part 1121 is used to prevent the bolt from falling out. Specifically, the anti-loosening limiting part 1121 reduces the cross-sectional area of ​​the opening of the fixing hole 112, preventing the bolt head from passing through the location of the anti-loosening limiting part 1121. For example, the normal fixing hole 112 has a circular cross-section. The anti-loosening limiting part 1121 and the fixing hole 112 cooperate to form a straight line and an arc, and its size is smaller than the size of the circle, thereby creating the effect of preventing the bolt from falling out. It should be noted that the terminal 18 was built-in in the early stage of installation, and the screwdriver could pass through the fixing hole 112 to engage with the bolt.

[0051] Specifically, as shown in the attached document Figure 6 As shown, it also includes an indicator light 19. The housing 11 includes a base 20 and a top cover 21, which cooperate to form a first receiving cavity 22. The socket module 12 is housed in the first receiving cavity 22. The socket module 12 includes a conductive sheet 122, which is electrically connected to the terminal block 18, forming an electrical connection between the external power supply circuit and the socket module 12. The external plug passes through the socket 121 and forms an electrical connection with the conductive sheet 122. The indicator light 19 is electrically connected to the conductive sheet 122. Specifically, the indicator light 19 is electrically connected to the neutral wire conductive sheet 122 and the live wire conductive sheet 122, forming an electrical circuit. This electrical circuit can directly supply power to the indicator light 19, or it can be connected in series with a resistor for voltage division. Those skilled in the art can adjust it according to actual needs. The boss portion 111 has a through hole, and the indicator light 19 is housed in the through hole. The indicator light 19 indicates whether the entire circuit is energized, serving as an indicator. The indicator light 19 indicates whether the socket module 12 is powered.

[0052] Specifically, it also includes a wire 23, one end of which is electrically connected to the indicator light 19, and the other end of which is electrically connected to the conductive sheet 122. The wire 23 and the conductive sheet 122 can be connected by soldering to achieve the electrical connection. Alternatively, the wire 23 and the indicator light 19 can be integrally formed. In this embodiment, the wire 23 is housed within the first receiving cavity 22.

[0053] Specifically, as shown in the attached document Figure 3 As shown, it also includes a wire 23 and an elastic conductive element 24. One end of the wire 23 is electrically connected to the indicator light 19, and the other end of the wire 23 is electrically connected to the elastic conductive element 24. One end of the elastic conductive element 24 abuts against the top surface of the first receiving cavity 22, and the other end of the elastic conductive element 24 abuts against the conductive sheet 122. Compared with the direct connection of the wire 23, this structure of the elastic conductive element 24 does not require welding, and the elastic conductive element 24 can also improve the stability of conductivity during compression. Here, the elastic conductive element 24 is specifically a spring. The upper cover 21 is provided with a fixing post that cooperates with the spring. The spring is sleeved on the fixing post, with one end of the spring abutting against the bottom surface of the upper cover 21 and the other end of the spring abutting against the conductive sheet 122. At this time, the wire 23 can pass through the area with a small pitch at the upper end of the spring to form a clamping fixation, thereby achieving the electrical connection effect. In addition, the wire 23 and the indicator light 19 can also be integrally formed.

[0054] Specifically, the socket 121 can be a two-hole, three-hole, five-hole, or small five-hole socket. Those skilled in the art can adjust the type of socket 121 according to actual needs to meet the requirements of different situations.

[0055] Specifically, a sealing structure is also provided between the top cover 21 and the base 20, such as a sealing ring (not shown in the attached drawings, but those skilled in the art should know how to set it up) or potting filler.

[0056] Specifically, the base 20 is also fixed with a mounting pad, which serves as a cushioning effect during installation.

[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
