Socket and discharge socket

Abstract

The application provides a socket and a discharge socket, and belongs to the technical field of sockets. The socket comprises a socket body and an upper cover. The top wall of the socket body is provided with a socket hole, and the side wall is provided with a wire slot extending along the height direction. The cable of the plug inserted into the socket hole penetrates into the wire slot and penetrates out through the lower end of the wire slot. The upper cover is used for covering the periphery of the socket body, and the side wall of the upper cover closes the slot opening of the wire slot. In this way, the socket only retains the downward opening of the wire slot in communication with the outside. In the scene of rain or lateral water spraying, it is difficult for water to enter the wire slot and the inside of the socket through the lower end opening of the wire slot. Moreover, even if a small amount of water splashes into the wire slot, it will flow out from the lower end opening of the wire slot under the action of gravity. It can be seen that the socket provided by the application has good waterproof performance.

Description

Technical Field

[0001] This application relates to the field of socket technology, and in particular to a socket and a discharge socket. Background Technology

[0002] A discharge socket is a device that allows electric vehicles or other equipment to output electrical energy. By equipping electric vehicles with discharge sockets, users can supply power to external devices during outdoor camping, outdoor work, and other scenarios, thus meeting their mobile power needs. A discharge socket typically consists of a discharge gun and a socket, which are connected by a cable. The discharge gun draws power from the electric vehicle, and the socket is used for discharging.

[0003] However, the outdoor environment is more complex and harsher than the indoor environment. For example, in the outdoor environment, the discharge socket may be exposed to high humidity, splashes, or even rain, which places higher demands on the waterproof performance of the socket itself. Summary of the Invention

[0004] This application provides a socket and a discharge socket. The socket has good waterproof performance. The technical solutions for the socket and the discharge socket are described below.

[0005] In a first aspect, this application provides a socket. The socket includes a socket body and a top cover. The top wall of the socket body is provided with a socket hole, and the side wall is provided with a cable routing groove, which extends along the height direction. The cable of a plug inserted into the socket hole passes through the cable routing groove and exits through its lower end. The top cover is used to cover the periphery of the socket body, and the upper side wall of the top cover obstructs the lateral opening of the cable routing groove.

[0006] In one implementation, the top cover includes a first top cover chamber and a second top cover chamber, with the first top cover chamber located above the second top cover chamber. When the top cover is positioned over the periphery of the socket body, the second top cover chamber accommodates the socket body, and the first top cover chamber accommodates a plug inserted into the socket.

[0007] In one implementation, an abutment portion is provided between the first and second upper cover chambers. When the upper cover is placed around the socket body, the abutment portion abuts against the top wall of the socket body.

[0008] In one implementation, the length of the first cover chamber is less than the length of the second cover chamber, and / or the width of the first cover chamber is less than the width of the second cover chamber, so as to form a stepped surface between the first cover chamber and the second cover chamber, the stepped surface being an abutment portion.

[0009] In one implementation, the top cover includes a first top cover portion and a second top cover portion. The first top cover portion has a first top cover chamber, and the second top cover portion has a second top cover chamber. The length of the first top cover portion is less than the length of the second top cover portion, and / or, the width of the first top cover portion is less than the width of the second top cover portion.

[0010] In one implementation, the socket further includes a sealing ring, which is pressed between the abutment portion and the top wall of the socket body, and the sealing ring is arranged around the socket hole. A wiring channel is provided on the outside of the sealing ring.

[0011] In one implementation, the top wall of the socket body has an annular groove, and a sealing ring is embedded in the annular groove. A sealing rib is provided on the abutment portion, which presses against the sealing ring, and the sealing rib breaks off at the wiring groove.

[0012] In one implementation, a wire clamping plate is provided inside the top cover. The wire clamping plate has a groove. When the top cover covers the periphery of the socket body, the cable is constrained within the space enclosed by the groove and the top wall of the socket body.

[0013] In one implementation, the pressure plate is parallel to the side wall where the cable tray is located.

[0014] In one implementation, a reinforcing plate is also provided inside the top cover. One end of the reinforcing plate is connected to the pressure plate, and the other end is connected to the side wall of the top cover. The pressure plate, the reinforcing plate, and the side wall of the top cover form an isolation cavity, which is located above the cable routing groove.

[0015] In one implementation, the reinforcing plate is perpendicular to the pressure plate.

[0016] In one implementation, a limiting plate is also provided inside the top cover. The limiting plate is located above the cable tray and is used to limit the upward displacement of the cable passing through the cable tray along the height direction.

[0017] In one implementation, the limiting plate is parallel to the pressure plate.

[0018] In one implementation, the side wall of the socket body is provided with multiple cable routing grooves, each groove being used to allow one cable to pass through.

[0019] In one implementation, a sealing plate is provided at the lower end of the cable tray, extending outward from the bottom of the cable tray to close a portion of the opening at the lower end of the cable tray.

[0020] In one implementation, a vertical plate is also provided in the cable tray. The vertical plate is connected to the end of the sealing plate away from the bottom of the cable tray. The vertical plate extends along the height direction, and its height is less than the dimension of the cable tray along the height direction. The cable is used to pass through the space enclosed by the vertical plate, the side wall of the top cover, and the side wall of the cable tray.

[0021] In one implementation, the socket body includes two short sidewalls arranged opposite each other along the length direction, and two long sidewalls arranged opposite each other along the width direction. The sidewall containing the cable tray is one of the two short sidewalls.

[0022] In one implementation, the top wall of the socket body has multiple sockets arranged sequentially along its length. Two long sidewalls are designated as a first long sidewall and a second long sidewall. Along the width direction, the cable routing groove is closer to the first long sidewall, and the multiple sockets are closer to the second long sidewall. The central axis of the sockets is inclined relative to both the length and width directions, causing the cable extending from the plug to extend towards the first long sidewall and the cable routing groove.

[0023] In one implementation, the sidewall of the socket body is higher than the surface of the socket hole, and the portion of the sidewall above this surface forms a cavity. A plug inserted into the socket is housed within this cavity. The sidewall also has a first cable entry point that connects the cavity to a cable tray, through which a cable is threaded into the cable tray.

[0024] In one implementation, a partition is provided inside the chamber, dividing the chamber into a receiving chamber and a waterproof chamber. The receiving chamber is used to accommodate the plug. The side wall surrounding the waterproof chamber is provided with a cable routing groove and a first cable entry port, and the partition is provided with a second cable entry port. The cable is sequentially passed through the second cable entry port and the first cable entry port into the cable routing groove.

[0025] In one implementation, the receiving cavity and the waterproof cavity are arranged sequentially along the length of the socket. Along the length, the sidewall containing the wiring trough and the first wiring opening is positioned opposite the partition.

[0026] In one implementation, the projection of the first threading opening onto the partition is offset from that of the second threading opening along the length direction.

[0027] In one implementation, the height of the bottom wall of the waterproof cavity near the first threading opening is lower than the height of the bottom wall of the waterproof cavity near the partition.

[0028] In one implementation, the inner surface of the top wall of the upper cover is provided with water-retaining ribs, and the water-retaining ribs and partitions extend in the same direction. When the upper cover is installed on the socket body, the water-retaining ribs and partitions are stacked and arranged along the length direction.

[0029] In one implementation, the socket body includes two short sidewalls arranged opposite each other along the length direction, and two long sidewalls arranged opposite each other along the width direction. The sidewall containing the cable tray is one of the two short sidewalls.

[0030] In one implementation, the top wall of the socket body has multiple sockets arranged sequentially along its length. Two long sidewalls are designated as the first and second long sidewalls. Along the width direction, the second wire insertion port is closer to the second long sidewall, the wire routing groove is closer to the first long sidewall, and the multiple sockets are closer to the first long sidewall. The central axis of the sockets is inclined relative to both the length and width directions, causing the cable extending from the plug to extend towards the second long sidewall and the second wire insertion port.

[0031] In one implementation, the bottom wall of the socket body includes a first bottom wall portion and a second bottom wall portion. The second bottom wall portion is higher than the first bottom wall portion, and the second bottom wall portion is provided with an opening at the lower end of the wiring groove.

[0032] In one implementation, the sidewall of the socket body is provided with at least two layers of water-retaining rings, which extend circumferentially along the socket body and break at the wiring groove. The at least two layers of water-retaining rings are spaced apart along the height of the socket body. When the top cover is installed around the socket body, the upper cover sidewall surrounds at least two layers of water-retaining rings.

[0033] In one implementation, the socket body includes two long sidewalls disposed opposite each other along its width. One side of the top cover is rotatably connected to one of the long sidewalls, and the other side of the top cover is used to engage with the other long sidewall.

[0034] In one implementation, the socket body includes two long sidewalls disposed opposite each other along its width. One side of the top cover is rotatably connected to one of the long sidewalls. The socket also includes a latch, which is rotatably connected to the other side of the top cover and is used to engage with the other long sidewall.

[0035] Secondly, this application provides a discharge socket. The discharge socket includes a discharge gun, a connecting cable, and a socket as described in any of the first aspects. The discharge gun is electrically connected to the socket body of the socket via the connecting cable.

[0036] The technical solution provided in this application includes at least the following beneficial effects.

[0037] The socket provided in this application has a cable routing groove extending along its height on the side wall of the socket body. The cable passes through the cable routing groove and exits through the lower opening of the groove. When the top cover is placed over the socket body, the side wall of the top cover blocks the opening of the cable routing groove. In this way, the socket only retains the downward opening of the cable routing groove for communication with the outside. In scenarios such as rain or side spraying of water, water is unlikely to enter the cable routing groove through the lower opening. Furthermore, even if a small amount of water splashes into the cable routing groove, the water will naturally drip out from the lower opening under the influence of gravity, making it difficult for water to enter the socket body along the cable routing groove, thereby effectively improving the waterproof performance of the socket.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0041] A power outlet is a device that allows electric vehicles or other equipment to output electrical energy. By equipping electric vehicles with power outlets, users can output electrical energy from their vehicles to external devices in scenarios such as outdoor camping and outdoor work, thereby meeting their mobile power needs.

[0042] For example, such as Figure 1 As shown, the discharge socket includes a socket 100 and a discharge gun 200, which are electrically connected via a connecting cable 300. The discharge gun 200 is used to plug into a discharge interface (also known as a charging interface) on the vehicle and can convert the electrical energy output from the discharge interface before outputting it to the socket 100.

[0043] Unlike conventional household sockets (i.e., power strips), the socket 100 in the discharge socket is designed for outdoor environments. Outdoor environments are more complex than indoor environments. In outdoor settings, the socket 100 is more susceptible to high humidity, splashes, and even rain, placing higher demands on its waterproof performance.

[0044] For example, current requirements stipulate that socket 100 in a discharge socket must pass a waterproof performance test. Among these requirements, Figure 2 The diagram illustrates a scenario for a waterproof performance test. (For example...) Figure 2 As shown, during the waterproof performance test, the socket 100 is placed horizontally and rotated 360°, and water is sprayed downwards from the side of the socket 100 (as indicated by the arrow). It is required that no water enters the interior of the socket 100 (such as the socket hole).

[0045] In view of the above-mentioned technical problems, this application provides a novel socket 100 (or power strip), which can be used in discharge sockets and has high waterproof performance. The socket 100 provided in this application embodiment is described below with reference to the accompanying drawings. The accompanying drawings of this application embodiment show two types of sockets 100. Figures 1-21 The attached diagram is for the first type of socket 100. Figures 22-36 The attached diagram shows the second type of socket 100.

[0046] The first type of socket 100 provided in the embodiments of this application will be described by way of example below. Figure 3 A schematic diagram of the first type of socket 100 after the top cover is closed is shown. Figure 4 An exploded view of the first type of socket 100 is shown. Figure 5 A schematic diagram of the bottom of the first type of socket 100 after the top cover is closed is shown. Figure 6 and Figure 7 A schematic diagram of the first type of socket 100 with its top cover opened is shown.

[0047] like Figures 3-7 As shown, the socket 100 provided in this embodiment includes a socket body 10 and a top cover 20. The top wall 13 of the socket body 10 is provided with a socket hole 131. The top cover 20 is used to cover the periphery of the socket body 10 to protect the socket hole 131. Wherein, as... Figure 4 As shown, the top cover 20 includes a top wall (referred to as the top cover top wall 21) and multiple side walls (referred to as the top cover side walls 22). The top cover top wall 21 and the top cover side walls 22 form a top cover chamber 23, which is used to accommodate the socket body 10 and the plug 400 inserted into the socket 131.

[0048] In the technical solution provided in this application embodiment, since the top cover 20 is installed around the socket body 10, external water will be blocked by the top cover 20, making it difficult for water to enter the socket hole of the socket body 10, thus effectively improving the waterproof performance of the socket body 10.

[0049] For ease of description, the socket 100 provided in the embodiments of this application, as follows Figure 3 As shown in the embodiment of this application, the socket 100 is defined in the length direction X, width direction Y, and height direction Z. The height direction Z can also be referred to as the thickness direction.

[0050] In some examples, such as Figure 6 and Figure 7 As shown, the top cover 20 is rotatably connected to the socket body 10. In this way, the user can protect and open the socket body 10 by flipping the top cover 20.

[0051] In some examples, such as Figure 6 and Figure 7 As shown, the socket body 10 includes two short sidewalls arranged opposite each other along the length direction X, and two long sidewalls arranged opposite each other along the width direction Y. One side of the upper cover 20 is rotatably connected to one of the long sidewalls.

[0052] In some examples, such as Figure 6 and Figure 7 As shown, the socket 100 also includes a latch 30, which is rotatably connected to the other side of the top cover 20 and is used to engage with another long side wall, thereby keeping the top cover 20 in a protected state.

[0053] Of course, in other examples, the socket 100 may not include the latch 30, and the other side of the top cover 20 may be directly engaged with another long side wall to achieve the closed fixation of the top cover 20 and the socket body 10.

[0054] It should be noted that since the socket body 10 needs to draw power from the connecting cable 300 and also needs to connect to the plug 400 and discharge through the cable 401, a corresponding wiring structure (such as a hole, slot, or opening) needs to be provided on the socket body 10 or the top cover 20 for the connecting cable 300 and the cable 401 to pass through. However, there may be gaps between the wiring structure and the cable, and there is a risk that external water may enter the socket body 10 through these gaps.

[0055] The sealing methods of the wiring structure corresponding to the connecting cable 300 and the wiring structure corresponding to the cable 401 of the plug 400 will be described by way of example below.

[0056] In some examples, such as Figure 7As shown, the wiring structure corresponding to the connecting cable 300 is the wiring hole 123 on the side wall 12 of the socket body 10. The socket 100 also includes a waterproof rubber ring 50, which surrounds the connecting cable 300 and is located at the wiring hole 123. This improves the sealing performance between the wiring hole 123 and the connecting cable 300.

[0057] Based on the same principle, to improve the sealing performance between cable 401 and the corresponding wiring structure, a corresponding seal can also be provided between cable 401 and the corresponding wiring structure. However, unlike the fixed and always-present connecting cable 300, cable 401 is movable, and cable 401 does not exist when the socket body 10 is not connected to the plug 400. This means that if a seal is used, the structure of the seal is more complex in terms of cost and implementation compared to the waterproof rubber ring 50.

[0058] Therefore, this application embodiment also provides another implementation method to prevent external water from entering the socket body 10 through the gap between the cable 401 and the wiring structure. Specifically, as... Figures 4-7 As shown, the side wall 12 of the socket body 10 is provided with a cable routing groove 121, which extends along the height direction Z. The cable 401 of the plug 400, which is inserted into the socket 131, passes through the cable routing groove 121 and exits through its lower end. When the upper cover 20 is placed over the socket body 10, the upper cover side wall 22 of the upper cover 20 blocks the lateral opening of the cable routing groove 121. The upper cover side wall 22 confines the cable 401 within the cable routing groove 121.

[0059] The wiring trough 121 extends along the height direction Z. The extension direction of the wiring trough 121 can be completely parallel to the height direction Z, or it can be inclined relative to the height direction Z, as long as the wiring trough 121 extends from the upper end to the lower end of the side wall 12. The upper cover side wall 22 covers the lateral opening of the wiring trough 121. This can be done by completely covering the lateral opening of the wiring trough 121, or by partially covering it. In some examples, the upper cover side wall 22 covers at least half of the lateral opening of the wiring trough 121.

[0060] In the technical solution provided in this application embodiment, the side wall 12 of the socket body 10 is provided with a wiring groove 121 extending along the height direction Z. The cable 401 passes through the wiring groove 121 and exits through the lower opening of the wiring groove 121. When the upper cover 20 covers the periphery of the socket body 10, the side wall 22 of the upper cover blocks the opening of the wiring groove 121. In this way, the socket 100 only retains the downward opening of the wiring groove 121 to communicate with the outside. In scenarios such as rain or side spraying water, water is unlikely to enter the wiring groove 121 through the lower opening. Furthermore, even if a small amount of water splashes into the wiring groove 121, the water will naturally flow out from the lower opening under the action of gravity, making it difficult for water to enter the interior of the socket body 10 along the wiring groove 121, effectively improving the waterproof performance of the socket 100.

[0061] In some examples, such as Figure 5 As shown, the bottom wall 11 of the socket body 10 includes a first bottom wall portion 111 and a second bottom wall portion 112. The second bottom wall portion 112 is higher than the first bottom wall portion 111, and the second bottom wall portion 112 is provided with an opening at the lower end of the wiring groove 121.

[0062] In this way, when the socket 100 is placed on a supporting surface (such as the ground), the first bottom wall portion 111 contacts the supporting surface, and the second bottom wall portion 112 forms a gap with the supporting surface. On the one hand, this gap provides bending and extension space for the cable 401 extending from the lower end of the cable tray 121, preventing the cable 401 from being squeezed. On the other hand, when there is water accumulation on the supporting surface, this gap keeps the second bottom wall portion 112 at a distance from the water on the supporting surface, preventing water from directly contacting the lower opening of the cable tray 121, further improving the waterproof performance of the socket 100.

[0063] In some examples, such as Figure 5 As shown, the height difference d1 between the second bottom wall portion 112 and the first bottom wall portion 111 is 7mm to 20mm. For example, d1 is 8mm to 15mm.

[0064] In some examples, such as Figure 5 As shown, the lower end face of the upper cover sidewall 22 is flush with the second bottom wall portion 112, or the lower end face of the upper cover sidewall 22 protrudes from the second bottom wall portion 112. In this way, the upper cover sidewall 22 surrounds the lower opening of the wiring trough 121. During waterproof testing or actual use, when water is encountered, after the water flow impacts the upper cover sidewall 22 laterally, it flows downwards along the outer surface of the upper cover sidewall 22, detaches at the lower end face of the upper cover sidewall 22, and drips downwards; or it is reflected outwards by the upper cover sidewall 22. In either case, water is less likely to enter the lower opening of the wiring trough 121, thereby further improving the waterproof performance of the socket 100.

[0065] Of course, in other examples, the lower end face of the upper cover sidewall 22 may also be slightly higher than the second bottom wall portion 112, for example, the height difference is within 2mm. In this case, the upper cover sidewall 22 can also block and guide the lower opening of the wiring channel 121, and external water still cannot directly enter the lower opening of the wiring channel 121.

[0066] It should be noted that the terms "high", "low" and "down" in this application embodiment are defined with the socket 100 placed horizontally on a supporting surface (such as the ground) as the reference.

[0067] In some examples, such as Figure 4 , Figure 6 and Figure 7 As shown, the socket body 10 includes two short sidewalls arranged opposite each other along the length direction X, and two long sidewalls arranged opposite each other along the width direction Y. The sidewall 12 where the cable tray 121 is located is one of the two short sidewalls.

[0068] In some examples, such as Figure 6 and Figure 7 As shown, the side wall 12 of the socket body 10 is provided with a plurality of cable routing grooves 121, each cable routing groove 121 being used for a cable 401 to pass through. For example, the plurality of cable routing grooves 121 are located on the short side wall and are arranged sequentially along the width direction Y.

[0069] In some examples, such as Figure 8 and Figure 9 As shown, the upper cover 20 includes an upper cover chamber 23. When the upper cover 20 covers the periphery of the socket body 10, a portion of the upper cover chamber 23 (i.e., the second upper cover chamber 232) accommodates the socket body 10, and another portion (i.e., the first upper cover chamber 231) is located above the socket body 10 and accommodates the plug 400 inserted into the socket 131. Figure 8 and Figure 9 This is a schematic diagram of the top wall of the top cover 20 of the first type of socket 100 after being cut open. The upper surface of the side wall 12 can be flush with the top wall 13 (or the plane where the socket 131 is located) or lower than the top wall 13 (or the plane where the socket 131 is located).

[0070] In some examples, such as Figure 6 And refer to Figure 8 and Figure 9As shown, the upper cover chamber 23 includes a first upper cover chamber 231 and a second upper cover chamber 232. When the upper cover 20 covers the socket body 10, the first upper cover chamber 231 is located above the second upper cover chamber 232. An abutment portion 233 is provided between the first upper cover chamber 231 and the second upper cover chamber 232. Specifically, when the upper cover 20 covers the periphery of the socket body 10, the second upper cover chamber 232 accommodates the socket body 10, the abutment portion 233 abuts against the top wall 13 of the socket body 10, and the first upper cover chamber 231 accommodates the plug 400 inserted into the socket 131.

[0071] In the technical solution provided in the embodiments of this application, when the upper cover 20 is covered on the socket body 10, it can abut against the top wall 13 of the socket body 10 through the abutment part 233, thereby limiting the displacement of the upper cover 20 in the height direction Z and improving the fit stability between the upper cover 20 and the socket body 10.

[0072] The implementation of the contact portion 233 in this application embodiment is not limited. In some examples, such as Figure 6 As shown, the length of the first upper cover chamber 231 is less than the length of the second upper cover chamber 232, and / or the width of the first upper cover chamber 231 is less than the width of the second upper cover chamber 232, so as to form a stepped surface between the first upper cover chamber 231 and the second upper cover chamber 232. This stepped surface is the aforementioned abutment portion 233.

[0073] In the technical solution provided in the embodiments of this application, by setting the size of the first upper cover chamber 231 to be smaller than the size of the second upper cover chamber 232, a stepped surface is naturally formed inside the upper cover chamber 23. This stepped surface is directly used as the abutment part 233, without the need for additional independent components, which simplifies the structure of the upper cover 20 and reduces the manufacturing difficulty and cost.

[0074] In some examples, such as Figure 6 As shown, the length of the first upper cover chamber 231 is less than the length of the second upper cover chamber 232, and the width of the first upper cover chamber 231 is less than the width of the second upper cover chamber 232. Thus, the stepped surface formed between the first upper cover chamber 231 and the second upper cover chamber 232 is an annular stepped surface, and the abutment portion 233 is distributed in a ring shape. When abutting against the top wall 13 of the socket body 10, the annular stepped surface provides a more uniform and continuous abutment effect, improving the reliability of the abutment and the stability of the fit between the upper cover 20 and the socket body 10.

[0075] In some examples, such as Figure 6 And refer to Figure 4As shown, the upper cover 20 includes a first upper cover portion 221 and a second upper cover portion 222. The first upper cover portion 221 has a first upper cover chamber 231, and the second upper cover portion 222 has a second upper cover chamber 232. The length of the first upper cover portion 221 is less than the length of the second upper cover portion 222, and / or the width of the first upper cover portion 221 is less than the width of the second upper cover portion 222. That is, the inner (upper cover chamber) and outer shapes of the first upper cover portion 221 and the second upper cover portion 222 are matched, both following a shape that is smaller at the top and larger at the bottom. The wall thickness of the first upper cover portion 221 and the second upper cover portion 222 can be the same.

[0076] In some examples, such as Figure 6 And refer to Figure 4 As shown, the length of the first upper cover portion 221 is less than the length of the second upper cover portion 222, and the width of the first upper cover portion 221 is less than the width of the second upper cover portion 222.

[0077] It should be noted that, in addition to being formed by a stepped surface, the abutment portion 233 can also be a structure such as a partition disposed in the upper cover chamber 23 in other examples. In this case, the dimensions of the first upper cover chamber 231 and the second upper cover chamber 232 can be the same.

[0078] In addition to infiltrating the socket body 10 through the wiring channel 121, external water may also infiltrate the socket body 10 through the gap between the socket body 10 and the top cover 20. Therefore, to improve the sealing performance between the socket body 10 and the top cover 20, in some examples, such as... Figure 6 , Figure 7 and Figure 10 As shown, the socket 100 also includes a sealing ring 40, which is pressed between the abutment portion 233 and the top wall 13 of the socket body 10, and the sealing ring 40 is arranged around a plurality of socket holes 131. In addition, a wiring groove 121 is provided on the outside of the sealing ring 40.

[0079] In the technical solution provided in this application embodiment, when water enters from the gap between the socket body 10 and the upper cover side wall 22, the water will be blocked by the sealing ring 40, thereby improving the waterproof performance of the socket 100.

[0080] In some examples, such as Figure 10 As shown, the top wall 13 of the socket body 10 is provided with an annular groove 132, and the sealing ring 40 is embedded in the annular groove 132. Figure 11 As shown, a sealing rib 2331 is provided on the abutment part 233, and the sealing rib 2331 presses against the sealing ring 40.

[0081] In the technical solution provided in this application embodiment, by embedding the sealing ring 40 into the annular groove 132, the sealing ring 40 can be limited, preventing the sealing ring 40 from shifting during use. At the same time, the sealing rib 2331 on the abutment portion 233 presses the sealing ring 40, so that the sealing ring 40 is clamped by the annular groove 132 and the sealing rib 2331, further improving the sealing effect.

[0082] In some examples, such as Figure 11 As shown, the sealing rib 2331 is broken at the cable tray 121. This avoids interference between the sealing rib 2331 and the cable 401, ensuring that the cable 401 can smoothly pass into the cable tray 121, and also avoids the risk of the sealing rib 2331 failing due to compression at the cable tray 121.

[0083] In some examples, such as Figures 7-9 As shown, a wire clamping plate 24 is provided inside the upper cover 20, and a groove 241 is provided on the lower end face of the wire clamping plate 24. When the upper cover 20 covers the periphery of the socket body 10, the cable 401 is constrained in the space enclosed by the groove 241 and the top wall 13 of the socket body 10. The wire clamping plate 24 can be located in the first upper cover cavity 231. In this way, the cable 401 is limited by the wire clamping plate 24 in the wiring path, preventing the cable 401 from moving or shifting randomly in the space between the socket body 10 and the upper cover 20, and ensuring the stability of the cable 401 wiring path.

[0084] In some examples, the bottom of the groove 241 presses against the cable 401.

[0085] In some examples, such as Figures 7-9 As shown, the pressure plate 24 is parallel to the side wall 12 where the cable tray 121 is located. For example, the cable tray 121 is located on a short side wall. The pressure plate 24 is parallel to the width direction Y.

[0086] In some examples, such as Figures 7-9 As shown, the two ends of the pressure plate 24 along the width direction Y are respectively connected to the two upper cover sidewalls 22.

[0087] In some examples, such as Figures 7-9 As shown, a reinforcing plate 25 is also provided inside the upper cover 20. One end of the reinforcing plate 25 is connected to the pressure plate 24, and the other end is connected to the side wall 22 of the upper cover. The pressure plate 24, the reinforcing plate 25, and the side wall 22 of the upper cover form an isolation cavity 250, which is located above the cable tray 121. For example, the reinforcing plate 25 is perpendicular to the pressure plate 24.

[0088] In the technical solution provided in this application embodiment, by setting the reinforcing plate 25, the structural strength of the wire clamping plate 24 is enhanced. On the other hand, the formed isolation cavity 250 is located above the wiring groove 121. When external water rises from bottom to top along the wiring groove 121, the isolation cavity 250 acts as an independent buffer, preventing water from easily entering the area inside the upper cover 20 that contacts the plug 400. Of course, due to the presence of the groove 241, the isolation cavity 250 cannot actually completely isolate external water from the socket 131.

[0089] In some examples, such as Figures 7-9 As shown, a limiting plate 26 is also provided inside the upper cover 20. Figure 13 and Figure 14 As shown, the limiting plate 26 is located above the cable tray 121 and is used to limit the upward displacement of the cable 401 along the height direction Z when it enters the cable tray 121. For example, the presence of the limiting plate 26 ensures that after the cable 401 enters the cable tray 121, it can only bend downwards.

[0090] In some examples, such as Figures 7-9 As shown, the limiting plate 26 is parallel to the pressure plate 24.

[0091] In some examples, such as Figures 7-9 As shown, the limiting plate 26 is located in the isolation cavity 250.

[0092] The internal structure of the wiring duct 121 will now be described by way of example. Figure 12 This is a magnified view of the wiring channel of the first type of socket. Figure 13 and Figure 14 This is a partial cross-sectional view of the first type of socket in the wiring trough.

[0093] In some examples, such as Figures 12-14 As shown, a sealing plate 1211 is provided at the lower end of the wiring trough 121. The sealing plate 1211 extends outward from the bottom of the wiring trough 121 to close a portion of the opening at the lower end of the wiring trough 121.

[0094] In the technical solutions provided in the embodiments of this application, such as Figure 13 and Figure 14 As shown, the cable 401 is curved in an arc (i.e. parabolic) shape within the cable tray 121. Compared to a right-angled bend, this curvature makes the cable 401 bend more gently, effectively reducing stress concentration at the bend and preventing damage to the cable 401 due to excessive bending.

[0095] For this curved shape, the depth of the cable tray 121 needs to be significantly greater than the diameter of the cable 401 to provide sufficient space for the curved bend. However, the actual path for the cable 401 to pass through the lower end of the cable tray 121 only occupies a portion of the lower opening (i.e., the side near the opening), while the space near the bottom of the tray is ineffective when the cable 401 passes through, which actually increases the risk of water ingress. Therefore, in this embodiment, a sealing plate 1211 is provided to close a portion of the lower opening of the cable tray 121. This reduces the effective area of ​​the lower opening without affecting the normal curved bend and smooth passage of the cable 401, thereby reducing the risk of external water entering the cable tray 121 through the lower opening and further improving the waterproof performance of the socket 100.

[0096] In some examples, such as Figures 12-14 As shown, a vertical plate 1212 is also provided in the cable tray 121. The vertical plate 1212 is connected to the end of the sealing plate 1211 away from the bottom of the cable tray 121. The vertical plate 1212 extends along the height direction Z, and its height is less than the dimension of the cable tray 121 along the height direction Z. Wherein, as... Figure 13 and Figure 14 As shown, cable 401 is used to pass through the space enclosed by the sidewall of vertical plate 1212, upper cover sidewall 22 and cable tray 121.

[0097] In the technical solution provided in this application embodiment, the vertical plate 1212 extends upward from the outer end of the sealing plate 1211, increasing the contact area between the inside of the cable tray 121 and the side wall of the cable 401. This provides a wider range of support and restraint in the lateral direction of the cable 401, preventing the cable 401 from shaking or shifting excessively in the cable tray 121, and ensuring the stability of the cable 401 routing path.

[0098] In some examples, such as Figure 13 and Figure 14 As shown, cable 401 passes between vertical plate 1212 and limiting plate 26.

[0099] In some examples, such as Figure 12 As shown, the two side walls of the cable tray 121 are provided with buckles 1213, which can be used to limit the cable 401.

[0100] In some examples, such as Figure 15 As shown, the sidewall 12 of the socket body 10 includes a first short sidewall 12a and a second short sidewall 12b arranged opposite each other along the length direction X, and a first long sidewall 12c and a second long sidewall 12d arranged opposite each other along the width direction Y. The wiring groove 121 is located on the first short sidewall 12a.

[0101] In some examples, such as Figure 15As shown, the top wall 13 of the socket body 10 is provided with multiple socket holes 131, which are arranged sequentially along the length direction X. Along the width direction Y, the cable tray 121 is closer to the first long sidewall 12c, and the multiple socket holes 131 are closer to the second long sidewall 12d. The central axis I of the socket holes 131 is inclined relative to both the length direction X and the width direction Y, causing the cable 401 extending from the plug 400 to extend towards the first long sidewall 12c and the cable tray 121, or rather, to have a tendency to extend towards the first long sidewall 12c and the cable tray 121. This facilitates the extension of the cable 401 to the cable tray 121 and prevents excessive bending of the cable 401.

[0102] The following is an exemplary description of how the socket body 10 and the top cover 20 are rotatably connected.

[0103] In some examples, such as Figure 16 and Figure 17 As shown, a first hinge portion 122 is provided on one long side wall of the socket body 10, and the first hinge portion 122 is provided with a first hinge shaft 1221. Figure 18 As shown, the upper cover 20 has a second hinge portion 223 on its upper cover side wall 22, and the second hinge portion 223 has a first hinge hole 2231. The first hinge shaft 1221 extends into the first hinge hole 2231, thereby realizing the rotatable connection between the socket body 10 and the upper cover 20.

[0104] In some examples, such as Figure 16 and Figure 17 As shown, the first hinge portion 122 is a protruding structure on the side wall 12 of the socket body 10. First hinge shafts 1221 are provided on both side walls of the first hinge portion 122 along the length direction X. Figure 18 As shown, the upper cover 20 has at least one pair of second hinge portions 223 on its upper cover sidewall 22, and each first hinge portion 122 extends into the pair of second hinge portions 223. The second hinge portion 223 can be a hinge plate.

[0105] In some examples, such as Figure 16 and Figure 17 As shown, the side wall 12 of the socket body 10 is provided with two second hinge parts 122, and a total of four first hinge axes 1221. Figure 18 As shown, the upper cover sidewall 22 is provided with two pairs of second hinge parts 223 and a total of four first hinge holes 2231.

[0106] In some examples, such as Figure 18 As shown, the second hinge portion 223 is disposed on the cavity wall of the second upper cover chamber 232.

[0107] It should be noted that in some examples, the positions of the first hinge shaft 1221 and the first hinge hole 2231 can be interchanged. That is, the first hinge hole 2231 can be provided in the first hinge portion 122, and the first hinge shaft 1221 can be provided in the second hinge portion 223.

[0108] The following is an exemplary description of how the latch 30 is rotatably connected to the top cover 20 and how the latch 30 is snapped into the socket body 10.

[0109] In some examples, such as Figure 19 and Figure 20 As shown, the upper cover 20 has a third hinge portion 224 on its upper cover side wall 22, and the third hinge portion 224 has a second hinge shaft 2241. Figure 21 As shown, the latch 30 includes a plate 31, and a fourth hinge portion 32 is provided on the side of the plate 31 facing the upper cover 20. The fourth hinge portion 32 is provided with a second hinge hole 321. The second hinge shaft 2241 extends into the second hinge hole 321, thereby realizing the rotational connection between the latch 30 and the upper cover 20.

[0110] In some examples, such as Figure 19 and Figure 20 As shown, the third hinge portion 224 is a protruding structure on the side wall 22 of the upper cover. Second hinge shafts 2241 are provided on both side walls of the third hinge portion 224 along the length direction X. (See diagram) Figure 21 As shown, the latch 30 is provided with at least one pair of fourth hinge portions 32, and each third hinge portion 224 extends between the pair of fourth hinge portions 32. The fourth hinge portion 32 can be a hinge plate.

[0111] In some examples, such as Figure 19 and Figure 20 As shown, the upper cover sidewall 22 is provided with two third hinge parts 224, for a total of four second hinge shafts 2241. (As...) Figure 21 As shown, the latch 30 is provided with a fourth hinge part 32, and a total of four second hinge holes 321.

[0112] In some examples, such as Figure 18 As shown, the second hinge portion 223 and the third hinge portion 224 are respectively provided on two oppositely arranged upper cover sidewalls 22. Furthermore, the second hinge portion 223 is provided on the inner side of the upper cover sidewall 22, and the third hinge portion 224 is provided on the outer side of the upper cover sidewall 22.

[0113] It should be noted that in some examples, the positions of the second hinge shaft 2241 and the second hinge hole 321 can be interchanged. That is, the second hinge hole 321 can be provided in the third hinge portion 224, and the second hinge shaft 2241 can be provided in the fourth hinge portion 32.

[0114] In some examples, such as Figure 6 and Figure 7 As shown, a plurality of first snap-fit ​​structures 18 are provided on the side wall 12 of the socket body 10. For example... Figure 21 As shown, the latch 30 includes a plurality of second latching structures 33, which are respectively latched with a plurality of first latching structures 18 to realize the latching of the latch 30 and the socket body 10.

[0115] The second type of socket 100 provided in the embodiments of this application will now be described by way of example. Figure 22 A schematic diagram of the second type of socket after the top cover is closed is shown. Figure 23 A schematic diagram of the bottom of the second type of socket after the top cover is closed is shown. Figure 24 A schematic diagram of the second type of socket with its top cover opened is shown. Figure 25 An exploded view of the second type of socket is shown. Figure 26 A schematic diagram of the second type of socket with the top cover concealed is shown.

[0116] like Figures 22-25 As shown, the second type of socket 100 provided in this application embodiment has the same core structure as the aforementioned first type of socket 100, that is, it also includes a socket body 10 and a top cover 20. The top wall 13 of the socket body 10 is provided with a socket hole 131, and the side wall 12 is provided with a cable routing groove 121. When the top cover 20 covers the periphery of the socket body 10, the side wall 22 of the top cover blocks the lateral opening of the cable routing groove 121 and constrains the cable 401 within the cable routing groove 121.

[0117] Alternatively, the wiring channel 121 can also be installed on the short side wall of the socket body 10.

[0118] like Figure 25 As shown, the second type of socket 100 also has a wire hole 123 on the side wall 12 of the socket body 10. The socket 100 also includes a waterproof rubber ring 50, which surrounds the connecting cable 300 and is located at the wire hole 123 to improve the sealing performance between the wire hole 123 and the connecting cable 300.

[0119] The following section focuses on describing the differences between the second type of socket 100 and the first type of socket 100.

[0120] In some examples, such as Figure 24 As shown, one side of the top cover 20 is rotatably connected to the socket body 10, and the other side is snapped into the socket body 10. In this way, the user can protect and open the socket body 10 by flipping the top cover 20, facilitating the insertion and removal of the plug 400.

[0121] In some examples, such as Figure 24As shown, the socket body 10 includes two short sidewalls arranged opposite each other along the length direction X, and two long sidewalls arranged opposite each other along the width direction Y. One side of the upper cover 20 is rotatably connected to one of the long sidewalls, and the other side of the upper cover 20 is snap-fitted to the other long sidewall.

[0122] It should be noted that the second type of socket 100 provided in this application embodiment can also use the latch 30 in the first type of socket 100 to achieve the snap-fit ​​between the upper cover 20 and the socket body 10, that is, the other side of the upper cover 20 is snapped to the corresponding long side wall through the latch 30. Similarly, the first type of socket 100 can also use the direct snap-fit ​​structure in the second type of socket 100, that is, the other side of the upper cover 20 is directly snapped to the corresponding long side wall. In other words, the above two connection methods (direct snap-fit ​​and snap-fit ​​through latch 30) can be used interchangeably, and this application embodiment does not specifically limit them.

[0123] In some examples, such as Figure 24 As shown, a cable routing groove 121 is provided on the side wall 12 of the socket body 10, which is used to allow multiple cables 401 to pass through. It should be noted that the above-mentioned solution of one cable routing groove 121 for multiple cables 401 can also be applied to the first type of socket 100; that is, a cable routing groove 121 can also be provided on the short side wall of the first type of socket 100, and multiple cables 401 can pass through this cable routing groove 121 together. Correspondingly, the second type of socket 100 can also adopt a solution of multiple cable routing grooves 121.

[0124] In some examples, such as Figure 24 and Figure 26 As shown, the side wall 12 of the socket body 10 is higher than the top wall 13 of the socket body 10, and the portion of the side wall 12 that is higher than the top wall 13 forms a cavity 14. Alternatively, the side wall 12 of the socket body 10 is higher than the surface where the socket hole 131 of the socket body 10 is located, and the portion of the side wall 12 that is higher than the surface forms a cavity 14.

[0125] The plug 400, which is inserted into the socket 131, is housed in the chamber 14. The side wall 12 is also provided with a first wire passage 1210, which connects the chamber 14 and the cable tray 121. The cable 401 is used to enter the cable tray 121 through the first wire passage 1210.

[0126] In some examples, such as Figure 24 and Figure 26As shown, a partition 15 is provided inside the chamber 14, dividing the chamber 14 into a receiving cavity 141 and a waterproof cavity 142. The receiving cavity 141 is used to receive the plug 400. Furthermore, the side wall 12 (which can be referred to as the waterproof cavity side wall) surrounding the waterproof cavity 142 is provided with a cable routing groove 121 and a first cable entry port 1210, and the partition 15 is provided with a second cable entry port 151. The cable 401 enters the cable routing groove 121 sequentially through the second cable entry port 151 and the first cable entry port 1210.

[0127] The top ends of the second threading opening 151 and the first threading opening 1210 are open, allowing the cable body of the cable 401 to be placed in the second threading opening 151 and the first threading opening 1210 through the top openings of the first threading opening 1210. Additionally, the second threading opening 151 and the first threading opening 1210 can also be used to limit the cable 401, such as by clamping the cable 401. In this case, the second threading opening 151 and the first threading opening 1210 can also be referred to as the first cable bundling opening and the second cable bundling opening.

[0128] In the technical solution provided in this application embodiment, the cable 401 passes sequentially through the second through-hole 151 on the partition 15, the first through-hole 1210 on the cavity wall of the waterproof cavity 142 (i.e., the side wall 12 used to enclose the waterproof cavity 142), and the cable tray 121 before exiting to the outside. Therefore, external water needs to flow upward through the gap between the cable tray 121 and the cable 401, and then enter the waterproof cavity 142 through the gap between the first through-hole 1210 and the cable 401. It then enters the receiving cavity 141 from the waterproof cavity 142 through the gap between the second through-hole 151 and the cable 401 before reaching the socket body 10. Both the cable tray 121 and the waterproof cavity 142 serve as intermediate transition spaces, buffering and intercepting externally intruding water, effectively preventing water from directly entering the receiving cavity 141 and contacting the socket body 10, thereby improving the waterproof performance of the socket 100.

[0129] Furthermore, even if the plug 400 is not plugged into the socket body 10 and the cable 401 is not present, external water must first enter the wiring trough 121 through the bottom opening, then enter the waterproof cavity 142 through the first wire insertion port 1210, and finally enter the receiving cavity 141 through the second wire insertion port 151. The wiring trough 121 and the waterproof cavity 142 successively form barriers and buffers for water, further reducing the risk of water directly intruding into the receiving cavity 141 and improving the waterproof performance of the socket 100.

[0130] In some examples, such as Figure 24 As shown, the receiving cavity 141 and the waterproof cavity 142 are arranged along the length direction X. This helps to reduce the width of the socket 100.

[0131] In some examples, such as Figures 24-27As shown, the side wall 12 where the cable tray 121 and the first cable opening 1210 are located is positioned opposite to the partition 15.

[0132] In some examples, such as Figures 24-27 As shown, along the direction perpendicular to the partition 15 (i.e., the length direction X), the projection of the first threading port 1210 on the partition 15 is offset from that of the second threading port 151. Thus, the second threading port 151 and the first threading port 1210 are misaligned and not on the same axis. Water entering the waterproof cavity 142 from the first threading port 1210 cannot reach the second threading port 151 in a straight line and must change direction to continue flowing, thereby further reducing the risk of water entering the receiving cavity 141.

[0133] In some examples, such as Figure 26 and Figure 27 As shown, the height of the end of the bottom wall 1420 of the waterproof cavity 142 near the first threading opening 1210 is lower than the height of the end of the bottom wall 1420 near the partition 15. This height difference in the bottom wall 1420 means that if water enters the waterproof cavity 142, it will naturally flow towards the lower end (i.e., the end near the first threading opening 1210) under gravity, and will not flow towards the partition 15, thereby reducing the risk of water entering the receiving cavity 141 through the second threading opening 151.

[0134] In addition, the height difference structure helps to guide the water in the waterproof cavity 142 to the vicinity of the first threading port 1210, so that the water can be discharged from the first threading port 1210 and avoid water accumulation in the waterproof cavity 142.

[0135] In some examples, such as Figure 27 As shown, the bottom wall 1420 of the waterproof cavity includes an inclined surface 1421, the height of the end of the inclined surface 1421 near the first wire opening 1210 is lower than the height of the end of the inclined surface 1421 near the partition 15. Of course, in some other examples, the inclined surface 1421 of the bottom wall 1420 of the waterproof cavity can also be replaced by a stepped surface, and this embodiment of the application does not limit this.

[0136] In some examples, such as Figure 27 As shown, the bottom wall 1420 of the waterproof cavity also includes a flat surface 1422, which is located on one side of the wiring groove 121 along the width direction Y.

[0137] In some examples, such as Figure 28 As shown, the bottom wall 11 of the socket body 10 includes a first bottom wall portion 111 and a second bottom wall portion 112. The second bottom wall portion 112 corresponds to the waterproof cavity 142 and has an opening at the lower end of the wiring groove 121. Therefore, the second bottom wall portion 112 is also the bottom wall 1420 of the waterproof cavity or its outer surface. The second bottom wall portion 112 is higher than the first bottom wall portion 111.

[0138] In this way, when the socket 100 is placed on a supporting surface (such as the ground), the first bottom wall portion 111 contacts the supporting surface, and the second bottom wall portion 112 forms a gap with the supporting surface. On the one hand, this gap provides bending and extension space for the cable 401 extending from the lower end of the cable tray 121, preventing the cable 401 from being squeezed. On the other hand, when there is water accumulation on the supporting surface, this gap keeps the second bottom wall portion 112 at a distance from the water on the supporting surface, preventing water from directly contacting the lower opening of the cable tray 121, further improving the waterproof performance of the socket 100.

[0139] In some examples, such as Figure 23 As shown, the height difference d2 between the outer surface of the bottom wall 1420 of the waterproof cavity (i.e., the second bottom wall portion 112) and the outer surface of the first bottom wall portion 111 is 20mm~40mm. For example, d2 is 32±5mm.

[0140] Of course, the numerical ranges of d1 and d2 mentioned above can also be used interchangeably. That is, the first type of socket 100 can also use the numerical range of d2 (such as 20mm~40mm), and the second type of socket 100 can also use the numerical range of d1 (such as 7mm~20mm). This application embodiment does not specifically limit this. Or, to put it another way, the numerical ranges of d1 and d2 mentioned above are both 7mm~40mm.

[0141] In some examples, such as Figure 28 and Figure 30 As shown, when the top cover 20 is placed around the socket body 10, the lower end face of the top cover side wall 22 of the top cover 20 is lower than the outer surface of the bottom wall 1420 of the waterproof cavity (i.e., the second bottom wall portion 112). In this way, the top cover side wall 22 surrounds the periphery of the waterproof cavity 142 and the lower end opening of the wiring groove 121.

[0142] like Figure 28 As shown, when water is encountered during waterproof testing or actual use, the water flow impacts the upper cover sidewall 22 from the side and flows downward along the outer surface of the upper cover sidewall 22, detaching at the lower end face of the upper cover sidewall 22 and dripping downward; or, it is reflected outward by the upper cover sidewall 22. In either case, the water flow is unlikely to contact the outer surface of the bottom wall 1420 of the waterproof cavity, thereby further improving the waterproof performance of the socket 100.

[0143] Of course, the lower end face of the upper cover side wall 22 can also be flush with the outer surface of the bottom wall 1420 of the waterproof cavity, or slightly higher than the outer surface of the bottom wall 1420 of the waterproof cavity (for example, the height difference is within 2mm).

[0144] In some examples, such as Figure 27As shown, the upper end face of the partition 15 protrudes relative to the upper end face of the side wall of the receiving cavity (i.e., the side wall 12 that forms the receiving cavity 141). Figure 29 and Figure 30 As shown, when the top cover 20 is placed over the socket body 10, the upper surface of the partition 15 abuts against the top cover 20. In this way, there is no gap between the partition 15 and the top wall 21 of the top cover, and water cannot enter the receiving cavity 141 through the upper surface of the partition 15, further improving the waterproof performance of the socket 100.

[0145] In some examples, such as Figure 27 As shown, the upper end face of the waterproof cavity sidewall (i.e., the sidewall 12 forming the waterproof cavity 142) protrudes relative to the upper end face of the receiving cavity sidewall. Figure 29 and Figure 30 As shown, when the top cover 20 is placed over the socket body 10, the upper surface of the waterproof cavity sidewall also abuts against the top cover 20. Thus, the upper surface of the waterproof cavity sidewall and the upper surface of the partition 15 abut against the top cover 20, forming a continuous sealed boundary around the top cover 20. Except for the second wiring port 151 and the first wiring port 1210, the waterproof cavity 142 no longer has any channels communicating with the receiving cavity 141 or the outside. This makes it more difficult for water to enter the waterproof cavity 142, and even more difficult for water to enter the receiving cavity 141 after entering the waterproof cavity 142, further improving the waterproof performance of the socket 100.

[0146] In some examples, such as Figure 29 As shown, when the top cover 20 is placed over the socket body 10, there is a gap between the top wall 21 of the top cover and the side wall of the receiving cavity. The presence of this gap can improve the reliability of the top wall 21 abutting against the upper end surface of the waterproof cavity side wall and the upper end surface of the partition 15.

[0147] In some examples, such as Figure 31 As shown, the top wall 21 of the upper cover 20 is provided with a water-retaining rib 27, and the water-retaining rib 27 and the partition 15 extend in the same direction (i.e., the width direction Y). Figure 29 and Figure 30 As shown, when the top cover 20 is placed over the socket body 10, the water-blocking ribs 27 and the partition 15 are stacked and arranged in a direction perpendicular to the partition 15 (i.e., the length direction X).

[0148] In the technical solution provided in this application embodiment, by arranging the water-blocking ribs 27 and partitions 15 in a layered manner, the resistance to water intrusion into the receiving cavity 141 in the waterproof cavity 142 can be increased. Specifically, if water seeps into the receiving cavity 141 from the joint between the upper cover 20 and the partition 15, it must first bypass the partition 15 and then bypass the water-blocking ribs 27 (or first bypass the water-blocking ribs 27 and then bypass the partition 15), and cannot directly enter the receiving cavity 141 in a straight line through the joint between the upper cover 20 and the partition 15. In this way, the intrusion path of water in the waterproof cavity 142 is lengthened and the resistance to water movement is increased, reducing the risk of water entering the receiving cavity 141.

[0149] In some examples, such as Figure 29 and Figure 30 As shown, the water-blocking ribs 27 are arranged on the side of the partition 15 near the receiving cavity 141. Of course, in other examples, the water-blocking ribs 27 may also be arranged on the side of the partition 15 near the waterproof cavity 142, and this embodiment does not specifically limit this.

[0150] In some examples, such as Figure 32 As shown, the sidewall 12 of the socket body 10 includes a first short sidewall 12a and a second short sidewall 12b arranged opposite each other along the length direction X, and a first long sidewall 12c and a second long sidewall 12d arranged opposite each other along the width direction Y. The wiring groove 121 is located on the first short sidewall 12a.

[0151] Along the width direction Y, multiple sockets 131 are closer to the first long sidewall 12c, the second cable entry 151 is closer to the second long sidewall 12d, and the cable tray 121 is closer to the first long sidewall 12c. The central axis I of the sockets 131 is inclined relative to both the length direction X and the width direction Y, causing the cable 401 extending from the plug 400 to extend towards the second long sidewall 12d and the second cable entry 151. In other words, it tends to extend towards the second long sidewall 12d and the second cable entry 151. This facilitates the cable 401 extending to the second cable entry 151 and prevents excessive bending of the cable 401.

[0152] It should be noted that, for the second type of socket 100 with a waterproof cavity 142, in some other examples, the wiring groove 121 may not be provided on the side wall of the socket body 10, and the waterproof performance of the socket 100 may be improved solely by the buffering and interception function of the waterproof cavity 142. For example, a first wire through-hole 1210 may be directly provided on the side wall 12 of the waterproof cavity 142, and the cable 401 may pass directly through the first wire through-hole 1210.

[0153] In addition to entering the interior of the receiving cavity 141 through the threaded structure, external water may also enter the interior of the receiving cavity 141 through the gap between the socket body 10 and the top cover 20.

[0154] Therefore, in order to improve the sealing performance between the socket body 10 and the top cover 20, in some examples, such as Figure 33 and Figure 34 As shown, at least two layers of water-retaining rings 16 are provided on the outer surface of the side wall 12 of the socket body 10, and the water-retaining rings 16 extend circumferentially along the socket body 10. Furthermore, the at least two layers of water-retaining rings 16 are spaced apart along the height direction Z of the socket body 10. Figure 35 As shown, when the top cover 20 is placed over the periphery of the socket body 10, the side wall 22 of the top cover surrounds at least two layers of water-retaining rings 16. For example, the outer surface of the side wall 12 of the socket body 10 is provided with two layers of water-retaining rings 16.

[0155] In the technical solution provided in this application embodiment, when water enters through the gap between the socket body 10 and the top cover 20, the water needs to pass through at least two layers of water-blocking rings 16. Each time it passes through a water-blocking ring 16, the direction and speed of water flow change, and energy is consumed step by step, making it difficult to pass through all the water-blocking rings 16 and enter the receiving cavity 141. This improves the waterproof performance of the socket 100.

[0156] in, Figure 35 The diagram shows the water flow path when water is sprayed from the side of the socket 100. (As shown) Figure 35 As shown, when water is sprayed from the side, some of the water is reflected by the side wall of the socket body 10 and flows upward. Due to the presence of the water-blocking ring 16, the upward-flowing water cannot enter the interior of the receiving cavity 141, thus improving the waterproof performance of the socket 100.

[0157] In some examples, such as Figure 33 As shown, the water-blocking ring 16 is disconnected at the opening of the cable tray 121.

[0158] It should be noted that the structure of the aforementioned water-retaining ring 16 can also be applied to the first type of socket 100. For example, at least two layers of water-retaining rings 16 can also be provided on the outer surface of the side wall 12 of the socket body 10 of the first type of socket 100. The water-retaining rings 16 extend circumferentially along the socket body 10 and are spaced apart along the height direction Z. When the upper cover 20 covers the periphery of the socket body 10, the side wall 22 of the upper cover surrounds at least two layers of water-retaining rings 16.

[0159] In some examples, such as Figure 35 and Figure 36 As shown, a support strip 17 is also provided on the outer surface of the side wall of the socket body 10, and the support strip 17 is located below the water-blocking ring 16. When the upper cover 20 is placed over the socket body 10, the upper cover 20 overlaps the support strip 17. The support strip 17 serves to support the upper cover 20.

[0160] The following is an exemplary description of how the socket body 10 and the top cover 20 are rotatably connected and snapped together.

[0161] In some examples, such as Figure 33 and Figure 34 As shown, the side wall of the socket body 10 is provided with a plurality of first hinge portions 122, and a first hinge shaft 1221 is provided on the first hinge portion 122. Figure 31 As shown, the upper cover 20 has a plurality of second hinge portions 223 on its upper cover sidewall 22, and each second hinge portion 223 has a first hinge hole 2231. The first hinge shafts 1221 of the plurality of first hinge portions 122 extend into the first hinge holes 2231 of the plurality of second hinge portions 223, thereby realizing the rotatable connection between the socket body 10 and the upper cover 20.

[0162] In some examples, both the first hinge portion 122 and the second hinge portion 223 are plate-shaped.

[0163] In some examples, such as Figure 33 and Figure 34 As shown, the side wall of the socket body 10 is provided with four first hinge portions 122. (As indicated...) Figure 31 As shown, the upper cover 20 is provided with four second hinge portions 223.

[0164] In some examples, such as Figure 33 and Figure 34 As shown, the first hinge shafts 1221 provided on two adjacent first hinge portions 122 in the plurality of first hinge portions 122 protrude in opposite directions. For example, as Figure 33 As shown, the first hinge shafts 1221 on the first and third first hinge portions 122 protrude in the same direction. The first hinge shafts 1221 on the second and fourth first hinge portions 122 also protrude in the same direction.

[0165] In some examples, such as Figure 33 and Figure 34 As shown, multiple first hinge portions 122 are disposed below multiple water-blocking rings 16, thereby preventing the placement of the first hinge portions 122 from damaging the water-blocking performance of the water-blocking rings 16.

[0166] In some examples, such as Figure 36 As shown, the side wall of the socket body 10 is provided with a plurality of first snap-fit ​​structures 18. The side wall 22 of the upper cover 20 is provided with a plurality of third snap-fit ​​structures 29. When the upper cover 20 covers the outside of the socket body 10, the plurality of first snap-fit ​​structures 18 respectively snap-fit ​​with the plurality of third snap-fit ​​structures 29. Wherein, by way of example, the first snap-fit ​​structure 18 is a snap-fit ​​protrusion, and the third snap-fit ​​structure 29 is a snap-fit ​​groove.

[0167] In some examples, such as Figure 36 As shown, multiple first snap-fit ​​structures 18 are arranged below multiple water-blocking rings 16, thereby preventing the arrangement of the first snap-fit ​​structures 18 from damaging the water-blocking performance of the water-blocking rings 16.

[0168] In some examples, such as Figure 35 and Figure 36 As shown, the top cover 20 is provided with a handle 28, which is used by the user to flip the top cover 20.

[0169] It should be noted that the implementation of the socket body 10 in this application embodiment is not limited. For example, in the first type of socket 100, such as Figure 4 As shown, the socket body 10 includes a housing and electrical components located within the housing. The housing includes a bottom shell 10a and a front panel 10b. The electrical components (such as sockets, switches, etc.) are housed in the bottom shell 10a, and the front panel 10b is used to close the opening of the bottom shell 10a. The front panel 10b has a top wall 13 of the socket body 10, and the bottom shell 10a has a bottom wall 11 and side walls 12 of the socket body 10. The front panel 10b may be higher than the bottom shell 10a.

[0170] In other examples, such as Figure 25 As shown, the socket body 10 includes a bottom shell 10a and a socket module. The socket module includes a socket housing and electrical components located within the socket housing. The socket module is located within the bottom shell 10a. The bottom shell 10a has a bottom wall 11 and a side wall 12 of the socket body 10. The socket housing of the socket module has a top wall 13.

[0171] It should also be noted that, according to testing, the two types of sockets 100 provided in this application embodiment can achieve IP55 level protection performance when the plug 400 is inserted (i.e., when the cable 401 is present). When the plug 400 is not inserted (i.e., when the cable 401 is not present), they can achieve IP54 level protection performance.

[0172] This application also provides a discharge socket. For example... Figure 1 As shown, the discharge socket includes a socket 100, a discharge gun 200, and a connecting cable 300. The socket body 10 of the socket 100 is electrically connected to the discharge gun 200 via the connecting cable 300. The connecting cable 300 can be a cable extending from the socket body 10, and this cable can be referred to as the socket cable.

[0173] This application does not limit the connection method between the connecting cable 300 and the discharge gun 200. In some examples, the connecting cable 300 and the discharge gun 200 are integrally connected or non-detachable. In other examples, the connecting cable 300 and the discharge gun 200 are detachably connected. For example, a connector is provided at the end of the connecting cable 300 away from the socket 100, and the connector is used to plug into the discharge gun 200.

[0174] It should be noted that the socket 100 provided in this application embodiment may not be used in a discharge socket. For example, the socket 100 may also draw power directly from a wall socket or other power strip.

[0175] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this application should be included within the protection scope of this application.
