Description

Technical Field

[0001] The utility model relates to a coupler sealing structure. Background Art

[0002] Small appliance couplers are also called small appliance connectors. They are components used to form electrical connections for small household appliances. Small appliance couplers usually include an upper coupler and a lower coupler. The upper coupler and the lower coupler are plugged and coupled to form an electrical connection between the small appliance and an external power source. The lower coupler is arranged on the chassis of the small appliance. The lower coupler includes a shell. The shell is provided with an electrical connection socket for matching with the upper coupling electrical connection column. Since various small appliances are placed and used in kitchens, restaurants and other places, and these small appliances are often exposed to liquids, a sealing structure is also provided at the connection of the electrical connection socket of the lower coupler. The sealing structure of the lower coupler in the prior art usually provides a sealing gasket layer, and the electrical connection socket is covered by the sealing gasket layer to achieve the purpose of waterproofing. However, the prior art is mainly aimed at electrical connection columns of smaller specifications. To this end, our company's prior application number "2023228838705" provides a lower coupler sealing structure, including an integrally formed sealing cover. In addition to the covering part, the sealing cover is also provided with a reinforcing part surrounding the covering part. The greater thickness of the reinforcing part ensures that the covering part will not open until it is subjected to a force that meets safety requirements, and can also ensure the strength of the covering part to better cope with large-sized electrical connection columns; and the sealing cover is arranged to be integrally formed, and the sealing cover is fixed at the end of the shell corresponding to the jack, so that the shell and the sealing cover are more integrated, and the sealing cover is prevented from being subjected to greater force, and its own structure or the connection structure between the shell is damaged. However, according to customer feedback from our company's existing design, the edge of the sealing cover near the upper end is pulled out by external force, which affects subsequent use. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a coupler sealing structure with greater stability while ensuring better handling of large-sized electrical connection columns.

[0004] To achieve the above-mentioned purpose, the utility model provides a coupler sealing structure, including a shell and a sealing cover, the shell including an outer shell and an inner bracket, a card groove for embedding the lower edge of the sealing cover is formed between the outer shell and the inner bracket, the sealing cover includes a covering part and a reinforcing part, the reinforcing part is arranged around the covering part, the thickness of the reinforcing part is greater than the thickness of the covering part, the outer shell includes an extending part, the extending part extends to be flush with the upper end surface of the sealing cover, and the extending part surrounds the sealing cover to cover it.

[0005] The advantages of adopting the above technical solution are: providing a shell and a sealing cover, dividing the shell into an outer shell and an inner bracket, forming a slot for embedding the lower edge of the sealing cover between the outer shell and the inner bracket, and providing a reinforcement portion in the sealing cover, so that the reinforcement portion has a larger thickness and surrounds the covering portion to ensure better handling of large-sized electrical connection columns. On this basis, an extension portion is provided on the outer shell, so that the extension portion is flush with the upper end surface of the sealing cover, and the extension portion surrounds the sealing cover to cover it, thereby avoiding the problem of the sealing cover being pulled out and damaged during use or installation, thereby ensuring the stability of the product.

[0006] The utility model can be further configured as follows: a retaining edge is provided at the upper end of the extension portion, the sealing cover includes grooves located at the edges of four sides thereof, and the retaining edge is bent toward the sealing cover and extends into the groove.

[0007] Through further configuration, a rib and a groove are respectively provided on the extension part and the sealing cover, and the rib is bent and extended into the groove. On the basis of allowing the extension part to cover the sealing cover, the sealing cover can also be limited by the rib, thereby further enhancing the stability of the product.

[0008] The utility model can be further configured as follows: the sealing cover includes a hook portion located at its lower edge, the outer wall of the hook portion is convex and snap-fitted with the inner wall of the outer shell, and the cross-section of the inner wall of the hook portion is inclined downward with a gradually increasing distance from the inner bracket.

[0009] Through further configuration, a hook is provided at the lower edge of the sealing cover, and its outer wall is protruding to engage with the outer shell sleeve, thereby strengthening the limiting effect of the retaining edge on the sealing cover, and then the cross-section of the inner wall of the hook is inclined, so that it is convenient to be sleeved on the inner bracket during installation.

[0010] The utility model can be further configured as follows: the outer shell includes a chamfer located between the extension portion and the retaining edge.

[0011] Through further configuration, a chamfer is provided at a position between the corresponding extension portion of the outer shell and the retaining edge to reduce the risk of collision and damage. BRIEF DESCRIPTION OF THE DRAWINGS
