[0001] The present invention relates to the field of electrical appliance accessories, and particularly to a fully assembled wall electrical appliance accessory. Background Art

[0002] With the continuous improvement of modern people's living needs, in the fields of decoration and home improvement, more and more people choose to find one or several relatively large companies to do the whole-house assembly including soft decoration, hard decoration, customized furniture, electrical appliances, and accessories. The whole-house assembly is a brand-new decoration mode after the overall home decoration, creating a new connotation of home decoration services. Users only need to purchase household appliances and daily necessities to move in, which can be said to be a real assembly.

[0003] In order to pursue fashion and beauty, people optimally match and combine the home furnishings with the areas of each hall and room in the house. The traditional method of first drilling holes in the wall to embed wire boxes and then installing switches, sockets, or other electrical appliance accessories into the wire boxes has been gradually phased out. In the whole-house assembly, there is no need to embed wire boxes in the wall, and the switches, sockets, or other electrical appliance accessories are directly installed on the furniture wall panels. This poses a new challenge to the thickness dimension of the electrical appliance accessories. The traditional wire box specifications are 8.6 cm * 8.6 cm * 4.5 cm, and the allowable thickness of the electrical appliance accessories is 3 cm to 4 cm. However, the thickness of the furniture wall panels in the whole-house assembly is 2.2 cm to 2.5 cm. Therefore, the existing electrical appliance accessories have the defect that they cannot be used in the whole-house assembly due to their too thick thickness. To solve the thickness problem of the existing electrical appliance accessories, this solution proposes a fully assembled wall electrical appliance accessory. Summary of the Invention

[0004] The invention purpose of the present invention is to solve the defect problem that the existing electrical appliance accessories cannot be used in the whole-house assembly due to their too thick thickness. The specific solution is as follows:

[0052] It should be specially noted that for the design principle of the electrical accessories in this solution, according to the needs of users, the functional components on the panel can also be designed as a switch button + two-hole socket, or a switch button + five-hole socket. Correspondingly, the power distribution module can be designed as a switch + two-hole socket, or a switch + five-hole socket. Therefore, the examples in this specific embodiment do not limit this solution.

[0053] In summary, adopting the technical solution of the present invention has the following beneficial effects:

[0054] This solution solves the defect problem of existing electrical accessories that they are too thick to be used in whole-house decoration. This solution uniquely adopts a brand-new wiring method: inserting the wiring from the side of the rear seat of the electrical accessory and vertically arranging the fastener from the front of the pressing plate. In this way, it is ensured that the depth of the electrical accessory inserted into the wall panel of the house is less than 18.5 mm, and the overall thickness of the electrical accessory is less than 23.5 mm. It is ultra-thin and fashionable, especially suitable for installing electrical accessories on the integral wall. It cancels the material cost of the traditional wire box and the drilling and installation costs. At the same time, this solution is also compatible with the installation of electrical accessories on the traditional wire box in the wall. The switch component product of this solution adopts the structure of a button + swing rod + swing block, which magnifies the 2-degree rotation angle of the button to the 4.8-degree rotation angle of the swing block, thereby reducing the protruding size of the button and ensuring the aesthetics of the electrical accessory. There are multiple reinforcing rib plates behind the fastener inside the rear seat of this solution, which ensures that the fastener is firmly fixed on the rear seat during wiring and is completely limited by the rib plates, avoiding deformation or fracture of the fastener, and thus can withstand the torsional wire pressure of 1.2 N·m for 5 times. The five-hole socket component product of this solution adopts the structure of a first safety door and a second safety door that move horizontally, improving the safety of the product and the convenience of unlocking operation. After the pressing plate and the rear seat are buckled, this solution can assemble and accurately position each part of the power distribution module, which is beneficial to the fastener to fix the wiring operation and the normal use of the button or socket, thereby improving the stability of the electrical accessory.
