Abstract
Description
Technical Field
[0001] The utility model relates to a plug-in unit, in particular to an internal plug-in unit of a household appliance. Background Art
[0002] Home appliances are household appliances, mainly referring to various electrical appliances and electronic devices used in homes and similar places. Home appliances free people from heavy, trivial and time-consuming housework, provide rich and colorful cultural and entertainment conditions, and have become a necessity of modern family life.
[0003] The interior of home appliances requires a variety of accessories to be assembled, and plug springs are one of the most commonly used plug-ins. The current plug spring structure is relatively simple, and most of them are made of metals such as alloys and pure copper in one piece. The conductive sheet connected to the pin is X-shaped or U-shaped. This easily causes problems such as large deflection in the plastic part, which pushes the pin on the pin seat, and a limited fitting area with the pin, which is prone to poor contact after long-term use. In addition, the plug spring has a simple structure and weak functionality, and there is no corresponding matching structure to ensure that its surface is not contaminated or deformed by external forces during transportation and processing. Utility Model Content
[0004] The purpose of the utility model is to provide an internal plug-in for household appliances to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an internal plug-in of a household appliance, comprising a connecting plate, a side wall of the connecting plate is provided with a plurality of plug spring bodies, one end of each of the plurality of plug spring bodies is provided with a bottom plate, both sides of the top of the bottom plate are provided with conductive sheets, a protective plate is provided between two opposite conductive sheets, the tops of the two side walls of the protective plate are fixedly connected with insulating cotton pads, the middle parts of the two side walls of the protective plate are fixedly connected with silicone plates, one end of the protective plate is fixedly connected with a sponge rod, and one side of each of the two sponge rods is provided with a flexible scraper.
[0006] As a preferred technical solution of the utility model, the connecting plate, the plug spring body, the bottom plate and the conductive sheet are integrally formed of brass.
[0007] As a preferred technical solution of the utility model, both sides of the bottom end of the protection plate are fixedly connected with cylinders, and the bottom end of the cylinder is fixedly connected with a vertical pole.
[0008] As a preferred technical solution of the utility model, a slide groove is provided in the middle of the top end of the bottom plate, and the vertical rod is slidably connected to the slide groove.
[0009] As a preferred technical solution of the utility model, a pair of springs are fixedly connected to the middle of the two side walls of the protection plate, and the back side of the silicone plate is in contact with the springs.
[0010] As a preferred technical solution of the utility model, the flexible scraper is fixedly arranged on the side wall of the protection plate.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model provides a pair of conductive sheets with bent ends that fit together. Compared with the traditional conductive sheets that fit together in an "X" shape, the structural advantages are: first, the deflection in the plastic part is small, and the pin seat will not be pushed; second, the contact area between the conductive sheet and the pin is large, the contact is good, and the phenomenon of poor contact is prevented.
[0013] 2. The utility model provides a protective plate placed between a pair of conductive sheets, which cooperates with the insulating cotton pads on both sides, so that the two conductive sheets can be respectively fitted and touched on the insulating cotton pads, so that during transportation or transmission, the conductive sheets can be prevented from being misaligned and colliding with each other, resulting in surface scratches. The provided silicone plate and spring can fully fit the silicone plate to the inner wall of the conductive sheet, and the inner wall is a contact conductive surface, so it is not easy to be contaminated during transportation and delivery. The provided sponge rod and flexible scraper can use the thrust of the pin when the subsequent pin is assembled for the first time to make the flexible scraper first scrape the surface of the conductive sheet to remove foreign matter that may be attached to the surface. The sponge rod that follows can be coated with a small amount of conductive paste in advance, so that better conductive contact can be achieved by applying the conductive paste in the subsequent long-term use. The protective plate and other structures can be removed after the first assembly of the pin, without affecting the integrity and conductivity of the plug. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 , the utility model provides a technical solution for the internal plug-in of household appliances:
[0021] according to Figure 1 , Figure 2 and Figure 3 , Figure 4 As shown, an internal plug-in of a household appliance comprises a connecting plate 1, a side wall of the connecting plate 1 is provided with a plurality of plug spring bodies 2, one end of each of the plurality of plug spring bodies 2 is provided with a bottom plate 3, both sides of the top of the bottom plate 3 are provided with conductive sheets 4, a protective plate 6 is provided between two opposite conductive sheets 4, the tops of the two side walls of the protective plate 6 are fixedly connected with insulating cotton pads 7, which shield and protect the conductive sheets 4 originally fitted to avoid direct scratches, the middle parts of the two side walls of the protective plate 6 are fixedly connected with silicone plates 8, which are made of elastic material and can be fitted on the conductive sheets 4 for shielding and protecting them, one end of the protective plate 6 is fixedly connected with a sponge rod 9, and one side of the two sponge rods 9 is provided with a flexible scraper 10.
[0022] The connecting plate 1, the plug spring body 2, the bottom plate 3 and the conductive sheet 4 are integrally formed of brass. When the protection plate 6 is no longer used, it needs to be removed, and the remaining connecting plate 1, the plug spring body 2, the bottom plate 3 and the conductive sheet 4 are the main structure.
[0023] The two sides of the bottom end of the protection plate 6 are fixedly connected with cylinders 11, the bottom end of the cylinder 11 is fixedly connected with a vertical rod 12, and a slide groove 5 is opened in the middle of the top end of the bottom plate 3, and the vertical rod 12 is slidably connected to the slide groove 5.

[0025] When used specifically, the utility model is an internal plug-in of a household appliance. During the transportation of the plug-in, the protection plate 6 can be inserted into the slide groove 5 with the help of the vertical rod 12, so that the protection plate 6 is placed between the two conductive sheets 4, and the conductive sheet 4 will directly contact the insulating cotton pad 7 to avoid mutual scratching due to transportation shaking. At the same time, the silicone plates 8 on both sides will be tightly fitted on the inner side wall of the conductive sheet 4 under the support of the spring 13, so that the inner side wall is shielded and protected to avoid surface contamination before assembly. During the assembly process, the pin will be inserted between the two conductive sheets 4, thereby synchronously pushing the protection plate 6 to move out between the two conductive sheets 4. During the movement, the two flexible scrapers 10 will scrape the surface of the conductive sheet 4 to remove foreign matter that may be attached. The sponge rod 9 that comes with it can be coated with a small amount of conductive paste in advance. In this way, when the protection plate 6 slides out between the two conductive sheets 4, the conductive paste can be coated on the conductive sheet 4 to enhance the conductive performance after subsequent assembly. At the same time, after the protection plate 6 is pushed out, the protection plate 6 can be removed from the bottom plate 3.
