Description

Technical Field

[0001] The utility model relates to the field of sockets, in particular to a waterproof discharge socket. Background Art

[0002] As we all know, under normal circumstances, plugs and sockets can only be used in water-free environments to prevent short-circuit failures. However, in actual use, plugs and sockets sometimes come into contact with water, such as in construction sites, outdoors, bathrooms, kitchens, and other places. In some scenarios, such as plugs and sockets on vehicles such as electric vehicles, water is easily able to enter the plug and socket when used outdoors. In order to ensure the electrical safety of plugs and sockets in various environments, plugs and sockets with waterproof functions are required. In the prior art, some waterproof plug and socket designs generally install a waterproof ring between the plug and socket, and the waterproof ring relies on the extrusion and deformation of the plug and socket to achieve sealing.

[0003] The inventors have found that the waterproof plugs and sockets in the prior art have at least the following disadvantages:

[0004] The waterproof ring is separated from the plug and socket and needs to be positioned and installed, which is inconvenient to operate and has problems such as sealing failure caused by poor positioning effect. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof discharge seat, which can reduce the difficulty of installation, improve the waterproof performance, extend the service life, and save the use cost.

[0006] The embodiment of the present utility model is achieved as follows:

[0007] In a first aspect, the utility model provides a waterproof discharge seat, comprising:

[0008] A discharge seat body, a conductive member and a sealing ring; the discharge seat body is provided with an annular groove, the groove wall surface of the annular groove is provided with a first concave-convex structure, the conductive member is mounted on the discharge seat body and is located within the area enclosed by the annular groove; the sealing ring is embedded in the annular groove, and the sealing ring forms a second concave-convex structure that engages with the first concave-convex structure at a position corresponding to the first concave-convex structure.

[0009] In an optional embodiment, the annular groove has an annular groove bottom wall and two annular groove side walls, the groove bottom wall is provided with an inner ring edge and an outer ring edge, and the two groove side walls are respectively connected to the inner ring edge and the outer ring edge.

[0010] Based on the above solution, the annular groove is a closed groove with no seam position. The bonding area between the annular groove and the sealing ring is large, the bonding is firm and reliable, and the sealing performance at the bonding position between the sealing ring and the annular groove is good, thereby improving the overall sealing performance.

[0011] In an optional embodiment, the first concave-convex structure is provided on the bottom wall of the groove.

[0012] Based on the above solution, the first concave-convex structure is distributed over a wide range and is firmly and reliably combined with the sealing ring.

[0013] In an optional embodiment, the first concave-convex structure is provided on at least one of the two groove side walls.

[0014] Based on the above solution, the first concave-convex structure is distributed over a wide range and is firmly and reliably combined with the sealing ring.

[0015] In an optional embodiment, the first concave-convex structure is configured as laser dermatoglyphics.

[0016] Based on the above solution, the first concave-convex structure has a simple structure, is easy to process, and has high molding quality. By engaging with the sealing ring, the bonding firmness between the discharge seat body and the sealing ring can be improved.

[0017] In an optional embodiment, the discharge seat body has a first side and a second side opposite to each other, the width of the first side is smaller than the width of the second side, the first side is provided with a mounting lug, and the mounting lug is provided with a first assembly hole;

[0018] The discharge seat body is provided with a second assembly hole close to the second side, and the second assembly hole is located outside the annular groove.

[0019] Based on the above solution, the discharge holder body is configured with one side wider and the other side narrower, which can save materials and reduce processing and manufacturing costs. The design of the first assembly hole and the second assembly hole allows the discharge holder body to be connected to a carrier such as a battery box using fasteners such as screws, making assembly convenient.

[0020] In an optional embodiment, there are multiple second assembly holes, and the multiple second assembly holes are all arranged close to the second side and are all located outside the annular groove.

[0021] Based on the above solution, by providing a plurality of second assembly holes, the firmness of the connection between the discharge seat body and a carrier such as a battery box can be improved.

[0022] In an optional embodiment, the annular groove is provided with an inner groove section for avoiding the second assembly hole and recessed toward the middle of the annular groove, the inner groove section having relative inner convex surface and outer concave surface, and the second assembly hole is provided on the side of the inner groove section corresponding to the outer concave surface.

[0023] Based on the above solution, by adjusting the extension shape of the annular groove, a processing position can be provided for the second assembly hole. Therefore, the size of the second side of the discharge seat body can be reduced, thereby reducing the volume of the discharge seat body, saving installation space resources, reducing consumables, and lowering processing and manufacturing costs.

[0024] In a second aspect, the present invention provides a production process for a waterproof discharge seat, which is applicable to any one of the aforementioned embodiments. The production process comprises the following steps:

[0025] Step s100, using a laser to process laser striae on the groove wall surface of the annular groove of the discharge seat body;

[0026] Step s200, preheating the discharge seat body formed with laser striae to a temperature of 120° C. to 160° C.;

[0029] In an optional embodiment, after step s100 and before step s200, the annular groove is cleaned and dried.

[0030] Based on the above solution, after cleaning the annular groove, there are fewer impurities in the annular groove, which reduces the probability of impurities occupying the installation space of the sealing ring, avoids the laser leather grain being filled with impurities, and does not affect the firmness of the sealing ring and the discharge seat body.

[0031] The beneficial effects of the embodiments of the present utility model are:

[0032] In summary, the waterproof discharge seat provided in this embodiment features an annular groove machined into the discharge seat body and a first concave-convex structure machined onto the wall surface of the annular groove. During assembly, a portion of the sealing ring is embedded in the annular groove, and the portion of the sealing ring corresponding to the first concave-convex structure of the annular groove adaptively deforms to form a second concave-convex structure that engages with the first concave-convex structure. This ensures that the sealing ring and the discharge seat body are positioned not only by the annular groove but also by the mutual engagement of the first and second concave-convex structures. This provides a secure and reliable bond between the sealing ring and the discharge seat body. During installation, the sealing ring is positioned securely on the discharge seat body, eliminating the need for further position adjustment, resulting in convenient and efficient assembly. Furthermore, the sealing performance between the sealing ring and the discharge seat body is determined by the contact area between the two. Because the sealing ring not only forms a sealing area in contact with the wall surface of the annular groove, but also forms a sealing area at the junction of the first and second concave-convex structures, this large sealing area provides a good sealing effect.

DETAILED DESCRIPTION

[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0042] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] In addition, the terms "horizontal" and "vertical" do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", not that the structure must be completely horizontal, but can be slightly tilted.

[0044] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0045] In the prior art, the sealing of the plug and the socket is achieved by a waterproof ring provided between the two. The waterproof ring is independent of the plug and the socket and is easy to lose. Moreover, during assembly, the position of the waterproof ring needs to be adjusted to correspond to the position of the plug and the socket, which makes assembly inconvenient. There is also a problem of sealing failure due to poor contact, resulting in poor sealing performance.

[0046] In view of this, the designer provides a waterproof discharge seat, which can improve the sealing performance, extend the service life and reduce the cost of use.

[0047] Please combine Figure 1-Figure 3 In this embodiment, the waterproof discharge seat includes a discharge seat body 100, a conductive member 200, and a sealing ring 300. The discharge seat body 100 is provided with an annular groove 101, and a first concave-convex structure 110 is provided on the groove wall surface of the annular groove 101. The conductive member 200 is mounted on the discharge seat body 100 and is located within the area enclosed by the annular groove 101. The sealing ring 300 is embedded in the annular groove 101, and the sealing ring 300 forms a second concave-convex structure 310 corresponding to the position of the first concave-convex structure 110 and meshing with the first concave-convex structure 110.

[0048] As described above, the waterproof discharge seat provided in this embodiment has an annular groove 101 machined on the discharge seat body 100 and a first concave-convex structure 110 machined on the groove wall surface of the annular groove 101. During assembly, a portion of the sealing ring 300 is embedded in the annular groove 101, and the position of the sealing ring 300 corresponding to the first concave-convex structure 110 of the annular groove 101 adaptively deforms to form a second concave-convex structure 310 that engages with the first concave-convex structure 110. In this way, the sealing ring 300 and the discharge seat body 100 are not only positioned by the annular groove 101, but also positioned by the mutual engagement of the first concave-convex structure 110 and the second concave-convex structure 310. The sealing ring 300 and the discharge seat body 100 are firmly and reliably bonded. During installation, the sealing ring 300 is positioned on the discharge seat body 100, and no further position adjustment operations are required, resulting in convenient assembly and high efficiency. At the same time, the sealing performance between the sealing ring 300 and the discharge seat body 100 is determined by the contact area between the two. Since the sealing ring 300 not only contacts the groove wall surface of the annular groove 101 to form a sealing area, but also forms a sealing area at the junction of the first concave-convex structure 110 and the second concave-convex structure 310, the sealing area is large and the sealing effect is good.

[0049] It should be understood that the waterproof discharge seat can be used for the electrical connection between the battery pack of the electrical equipment and the electrical components. The battery pack can be a portable battery pack, a hand-grabbed battery pack, etc. The installation position of the battery pack can cover all the lower tubes of the electric vehicle. The battery pack can be matched with the upper, lower, side and other methods.

[0050] In addition, electrical equipment may be, but is not limited to, industrial equipment such as forklifts, stackers, electric bicycles, electric motorcycles, new energy and electric energy storage.

[0051] The detailed structure of the waterproof discharge seat according to the embodiment of the present application is described below by way of example.

[0052] Please combine Figure 2 In this embodiment, the annular groove 101 optionally includes an annular bottom wall 102 and two annular side walls 103. The bottom wall 102 is provided with an inner ring edge and an outer ring edge, and the two side walls 103 are connected to the inner ring edge and the outer ring edge, respectively. The annular groove 101 is a closed groove with no seam. The annular groove 101 and the sealing ring 300 have a large bonding area, making the bonding firm and reliable. The sealing performance at the bonding point between the sealing ring 300 and the annular groove 101 is good, thereby improving the overall sealing performance.

[0053] Optionally, the first concavo-convex structure 110 is provided on the groove bottom wall 102, or at least one of the two groove side walls 103 is provided with the first concavo-convex structure 110. For example, in this embodiment, the first concavo-convex structure 110 is provided on the groove bottom wall 102, and at the same time, the first concavo-convex structure 110 is provided on both groove side walls 103.

[0054] With such a design, the first concave-convex structure 110 is distributed over a wide range, and the area for combining with the sealing ring 300 is large, so that the discharge seat body 100 and the sealing ring 300 are firmly and reliably matched.

[0055] It should be noted that the first concave-convex structure 110 can be configured as laser leather grain. The first concave-convex structure 110 has a simple structure, is easy to process, has high molding quality, and can enhance the bonding strength between the discharge seat body 100 and the sealing ring 300 by interlocking with the sealing ring 300.

[0056] Furthermore, the sealing ring 300 can be integrated with the discharge base body 100. For example, after the sealing ring 300 is embedded in the discharge base body 100, it is then integrated into the body 100 using a hot melt process. This creates a secure bond between the sealing ring 300 and the discharge base body 100, providing close contact and a tight fit, significantly enhancing the sealing level and effectiveness. This reduces the impact of high and low temperature climate fluctuations on the sealing ring 300, extending its lifespan to over three times that of existing sealing structures. Furthermore, the product's flat dimensional consistency is more stable, effectively improving product differentiation through the sealing ring assembly.

[0057] Please combine Figure 2In this embodiment, the discharge seat body 100 optionally has a first side and a second side opposite to each other, the first side being narrower than the second side, and a mounting lug 120 protruding from the first side, with a first assembly hole 121 defined in the mounting lug 120. The number of mounting lugs 120 may be one or more. For example, in this embodiment, there is one mounting lug 120 located in the middle of the first side.

[0058] Furthermore, the discharge holder body 100 is provided with a second assembly hole 130 near the second side, located outside the annular groove 101. This design allows the discharge holder body 100 to have a wide side and narrow side, saving material and reducing manufacturing costs. The design of the first assembly hole 121 and the second assembly hole 130 facilitates the connection of the discharge holder body 100 to a carrier such as a battery pack using fasteners such as screws.

[0059] Optionally, there are multiple second assembly holes 130, each of which is disposed near the second side and outside the annular groove 101. For example, in this embodiment, there are two second assembly holes 130. Providing multiple second assembly holes 130 can enhance the secure connection between the discharge holder body 100 and a carrier such as a battery pack.

[0060] In this embodiment, the annular groove 101 optionally includes an inner groove segment 104 recessed toward the center of the annular groove 101 to accommodate the second assembly hole 130. The inner groove segment 104 has opposing inner convex and outer concave surfaces, and the second assembly hole 130 is provided on the side of the inner groove segment 104 corresponding to the outer concave surface. By adjusting the extension of the annular groove 101, a machining position can be provided for the second assembly hole 130. This reduces the size of the second side of the discharge holder body 100, thereby reducing the volume of the discharge holder body 100, conserving installation space, reducing consumables, and lowering manufacturing costs.

[0061] It should be noted that when the number of the second assembly holes 130 is two, the number of the inner groove sections 104 of the annular groove 101 is also two. In this way, each second assembly hole 130 is correspondingly arranged at the position of the inner groove section 104, which can reduce the volume of the discharge seat body 100 and facilitate assembly.

[0062] In this embodiment, the waterproof discharge seat provided by the present invention securely bonds the sealing ring 300 to the discharge seat body 100, providing excellent sealing performance. This eliminates the need for a positioning ring 300, improving the efficiency of assembly between the discharge seat body 100 and a plug or socket. The discharge seat body 100 can be either a plug or a socket. Correspondingly, the conductive member 200 can be a conductive post or a conductive cylinder.

[0063] This embodiment also provides a production process for a waterproof discharge seat, which is used to process the above-mentioned waterproof discharge seat. The production process includes the following steps:

[0064] Step s100 : using a laser to process laser graining on the groove wall surface of the annular groove 101 of the discharge seat body 100 . The laser graining can be formed on the groove bottom wall 102 and two groove side walls 103 of the annular groove 101 .

[0065] Step s200: preheating the discharge seat body 100 formed with laser leather grain and making the temperature of the discharge seat body 100 reach 120°C-160°C. For example, the preheating temperature of the discharge seat body 100 can be 120°C, 140°C or 160°C, etc., wherein, by preheating the discharge seat body 100, it is convenient to insert the sealing ring 300 into the annular groove 101.

[0066] Step s300: Use the mold to position the discharge holder body 100 and the sealing ring 300 within the annular groove 101. During operation, the discharge holder body 100 can be positioned on the lower mold base, and the sealing ring 300 can be positioned on the upper mold base. The upper and lower mold bases are matched. When the upper and lower mold bases are closed, the sealing ring 300 is embedded in the annular groove 101, thereby achieving positioning of the sealing ring 300 and the annular groove 101. The operation is convenient and the positioning quality is high.

[0067] Step s400: Ultrasonic vibration heat-seals the positioned discharge base body 100 and the sealing ring 300, with the heat-seal time controlled between 43 and 48 seconds. Ultrasonic vibration heat-seals the sealing ring 300 relative to the discharge base body 100 during deformation, allowing the sealing ring 300 to better fill the laser grain lines and form a mutually interlocking structure. This ensures a secure bond between the sealing ring 300 and the discharge base body 100, ensuring a good seal.

[0068] Optionally, after step s100 and before step s200, the annular groove 101 is cleaned and dried. Cleaning the annular groove 101 reduces impurities, reducing the probability of impurities occupying the installation space of the sealing ring 300, preventing impurities from filling the laser striae, and not affecting the secure connection between the sealing ring 300 and the discharge seat body 100. After cleaning, the annular groove 101 can be dried naturally or in a drying machine.

[0069] The waterproof discharge seat production process provided in this embodiment has good sealing performance, is easy to install, and has a long service life.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
