Description

Technical Field

[0001] The invention relates to the field of sockets, and in particular to a waterproof discharge socket and a production process of the waterproof discharge socket. Background Art

[0002] As we all know, under normal circumstances, plugs and sockets can only be used in a waterless environment to prevent short circuit failures. However, in actual use, plugs and sockets sometimes come into contact with water, such as in engineering, outdoors, bathrooms, kitchens and other places. In some other scenarios, such as plugs and sockets on vehicles such as electric vehicles, water is also easy to enter the plug and socket position when used outdoors. In order to ensure the electrical safety of plugs and sockets in a variety of 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 the socket, and the waterproof ring relies on the extrusion deformation of the plug and the 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 due to poor positioning effect. Summary of the invention

[0005] The purpose of the present invention is to provide a waterproof discharge seat and a production process of the 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 invention is achieved as follows:

[0007] In a first aspect, the present invention 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, a first concave-convex structure is provided on the groove wall surface of the annular groove, the conductive member is mounted on the discharge seat body and is located in the area surrounded 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 scheme, the annular groove is a closed groove without any joint 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, at least one of the two groove side walls is provided with the first concave-convex structure.

[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, has high molding quality, and can improve the firmness of the combination between the discharge seat body and the sealing ring by engaging with the sealing ring.

[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 convexly 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 seat body is set to a structure with one side wide and the other side narrow, which can save materials and reduce processing and manufacturing costs. Through the design of the first assembly hole and the second assembly hole, the discharge seat body can be connected to a carrier such as a battery box through fasteners such as screws, which is easy to assemble.

[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 which is recessed toward the middle of the annular groove and is used to avoid the second assembly hole. The inner groove section has relative inner convex surfaces and outer concave surfaces, and the second assembly hole is provided on one side of the inner groove section corresponding to the outer concave surface.

[0023] Based on the above scheme, by adjusting the extension shape of the annular groove, a processing position can be provided for the second assembly hole, thereby reducing the size of the second side of the discharge seat body, thereby reducing the volume of the discharge seat body, saving installation space resources, reducing consumables, and reducing 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 the waterproof discharge seat described in any one of the aforementioned embodiments, and the production process comprises the following steps:

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

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

[0030] Based on the above scheme, 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 invention are:

[0032] In summary, the waterproof discharge seat provided in this embodiment is processed on the discharge seat body by machining an annular groove and processing a first concavo-convex structure on the groove wall surface of the annular groove. During assembly, part of the sealing ring is embedded in the annular groove, and the position corresponding to the first concavo-convex structure of the annular groove on the sealing ring is adaptively deformed to form a second concavo-convex structure that engages with the first concavo-convex structure. In this way, the sealing ring and the discharge seat body are not only positioned by the annular groove, but also positioned by the mutual engagement of the first concavo-convex structure and the second concavo-convex structure. The combination of the sealing ring and the discharge seat body is firm and reliable. During installation, the sealing ring is positioned on the discharge seat body, and no position adjustment and other operations are required. The assembly is convenient and efficient. At the same time, the sealing performance between the sealing ring and the discharge seat body is determined by the contact area between the two. Since the sealing ring not only contacts the groove wall surface of the annular groove to form a sealing area, the first concavo-convex structure and the second concavo-convex structure are also formed at the combination position. The sealing area is large and the sealing effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the prior art, the sealing of the plug and the socket is achieved by a waterproof ring arranged between the two. The waterproof ring is independent of the plug and the socket and is easy to lose. During assembly, the waterproof ring needs to be adjusted to the position of the plug and the socket, which is inconvenient to assemble. There is a problem of sealing failure caused by poor contact, and the sealing performance is poor.

[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; an annular groove 101 is provided on the discharge seat body 100, and a first concave-convex structure 110 is provided on the groove wall surface of the annular groove 101; the conductive member 200 is installed on the discharge seat body 100 and is located in the area surrounded by the annular groove 101; the sealing ring 300 is embedded in the annular groove 101, and the sealing ring 300 corresponds to the position of the first concave-convex structure 110 to form a second concave-convex structure 310 that bites with the first concave-convex structure 110.

[0048] Based on the above, the waterproof discharge seat provided in the present embodiment is provided with an annular groove 101 processed on the discharge seat body 100, and a first concavo-convex structure 110 processed on the groove wall surface of the annular groove 101. During assembly, part of the sealing ring 300 is embedded in the annular groove 101, and the position of the sealing ring 300 corresponding to the first concavo-convex structure 110 of the annular groove 101 is adaptively deformed to form a second concavo-convex structure 310 engaged with the first concavo-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 concavo-convex structure 110 and the second concavo-convex structure 310. The sealing ring 300 and the discharge seat body 100 are firmly and reliably combined. During installation, the sealing ring 300 is positioned on the discharge seat body 100, and no position adjustment and other operations are required. The assembly is convenient and efficient. 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 combination position 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 upper removal, lower removal, side removal 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] In this embodiment, the annular groove 101 optionally has an annular groove bottom wall 102 and two annular groove side walls 103, the groove bottom wall 102 is provided with an inner ring edge and an outer ring edge, and the two groove side walls 103 are respectively connected to the inner ring edge and the outer ring edge. The annular groove 101 is a closed groove, and there is no seam position. The annular groove 101 and the sealing ring 300 have a large bonding area, and the bonding is firm and reliable. The sealing performance at the bonding position of the sealing ring 300 and the annular groove 101 is good, thereby improving the overall sealing performance.

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

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

[0055] It should be noted that the first concavoconvex structure 110 can be configured as laser leather grain. The first concavoconvex structure 110 has a simple structure, is easy to process, has high molding quality, and can improve the firmness of the combination of the discharge seat body 100 and the sealing ring 300 by engaging with the sealing ring 300.

[0056] In addition, the sealing ring 300 can be set as an integrated structure with the discharge seat body 100. For example, after the sealing ring 300 is embedded in the discharge seat body 100, the sealing ring 300 and the discharge seat body 100 are combined into one by using a hot melt process. The sealing ring 300 and the discharge seat body 100 are firmly combined, and the contact and fit are tight, and the sealing level and sealing effect are greatly improved. In this way, the sealing ring 300 is less affected by high and low temperature climate changes, and the service life can reach more than 3 times that of the existing sealing structure; the consistency of the flat size of the product is more stable, which effectively improves the differentiation of the product by the sealing ring assembly.

[0057] Please combine Figure 2In this embodiment, optionally, the discharge seat body 100 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 convexly provided with a mounting lug 120, and the mounting lug 120 is provided with a first assembly hole 121. The number of the mounting lugs 120 can be one or more, for example, in this embodiment, the number of the mounting lugs 120 is one and is located in the middle of the first side.

[0058] At the same time, the discharge seat body 100 is provided with a second assembly hole 130 close to the second side, and the second assembly hole 130 is located outside the annular groove 101. With such a design, the discharge seat body 100 is configured to have a structure with one side wide and the other side narrow, which can save materials and reduce processing and manufacturing costs. Through the design of the first assembly hole 121 and the second assembly hole 130, the discharge seat body 100 can be connected to a carrier such as a battery box by fasteners such as screws, and assembly is convenient.

[0059] Optionally, there are multiple second assembly holes 130, and the multiple second assembly holes 130 are all arranged close to the second side and are all located outside the annular groove 101. For example, in this embodiment, there are two second assembly holes 130. By providing multiple second assembly holes 130, the firmness of the connection between the discharge seat body 100 and a carrier such as a battery box can be improved.

[0060] In this embodiment, the annular groove 101 is optionally provided with an inner groove section 104 which is used to avoid the second assembly hole 130 and is recessed toward the middle of the annular groove 101. The inner groove section 104 has an inner convex surface and an outer concave surface relative to each other, and the second assembly hole 130 is provided on a side of the inner groove section 104 corresponding to the outer concave surface. By adjusting the extension form of the annular groove 101, a processing position can be provided for the second assembly hole 130, so that the size of the second side of the discharge seat body 100 can be reduced, thereby reducing the volume of the discharge seat body 100, saving installation space resources, reducing consumables, and reducing processing and 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 the waterproof discharge seat provided in this embodiment, the sealing ring 300 is firmly combined with the discharge seat body 100, has good sealing performance, and eliminates the role of positioning the sealing ring 300, thereby improving the assembly efficiency of the discharge seat body 100 and the plug or socket. The discharge seat body 100 can be a plug or a socket. Correspondingly, the conductive member 200 can be a conductive column or a conductive cylinder.

[0063] This embodiment also provides a waterproof discharge seat production process, which is used to process the 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, using the mold to position the discharge seat body 100 and the sealing ring 300 located in the annular groove 101. During operation, the discharge seat body 100 can be positioned on the lower mold base, and the sealing ring 300 can be positioned on the upper mold base, and the upper mold base and the lower mold base are matched. When the upper mold base and the lower mold base are molded together, the sealing ring 300 is embedded in the annular groove 101, thereby realizing the positioning of the sealing ring 300 and the annular groove 101, which is easy to operate and has high positioning quality.

[0067] Step s400, using ultrasonic vibration to heat-melt the discharge seat body 100 and the sealing ring 300 in the positioning state, and the heat-melting time is controlled at 43s-48s. Through ultrasonic vibration heat-melting, the sealing ring 300 can produce relative movement with the discharge seat body 100 during the deformation process, so that the sealing ring 300 can better fill the laser leather grain and form a mutual bite structure. The sealing ring 300 and the discharge seat body 100 are firmly combined and have good sealing performance.

[0068] Optionally, after step s100 and before step s200, the annular groove 101 is cleaned and dried. After cleaning the annular groove 101, there are fewer impurities in the annular groove 101, which reduces the probability of impurities occupying the installation space of the sealing ring 300, avoids the laser leather grain being filled with impurities, and does not affect the firmness of the sealing ring 300 and the discharge seat body 100. After cleaning, it can be dried naturally or by using a drying device.

[0069] The waterproof discharge seat production process provided in this embodiment has good sealing performance, convenient installation and long service life.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
