Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sockets, in particular to a strong current module of a polyhedral socket and a polyhedral socket. BACKGROUND

[0002] In order to meet the increasing power supply demand of electrical appliances and digital devices, the product category of the power strip (extension cord / wiring board / socket / socket extension / socket extension) meets the functional supplement of the wall socket in terms of power supply distance and the number of holes. After years of development and extensive application in furniture environment, people have higher requirements for the appearance modeling, volume control and aesthetic pursuit of the power strip. Therefore, many products that break through the traditional long strip shape and linear arrangement of the jack have been born in the market. The cuboid-shaped socket is one of them. Each jack of this type of socket is distributed on different surfaces of the cuboid, avoiding interference between multiple electrical devices when they are connected at the same time. It is convenient to carry, novel in modeling, and easy to associate with the toy Rubik's Cube, so it is very popular with consumers and is also called the Rubik's Cube socket.

[0003] The appearance form of the Rubik's Cube socket requires the design of the internal structure. The ground, fire, zero conductive structure, insulating parts, protection door (safety door), strong and weak current voltage conversion structure, USB interface and other components need to be reasonably stacked in a small volume to maintain compactness and not waste any space.

[0004] The existing Rubik's Cube socket product includes three layers of metal conductive sheets - zero line conductive sheet, ground line conductive sheet and fire line conductive sheet, which are integrally punched (or riveted) by copper sheets and then bent into shape (insert sleeve) for cooperation with the plug of the electrical appliance. It also includes at least two layers of plastic partitions - which are used to fix and isolate the three layers of conductive sheets. A plurality of plastic partitions are fixed by a buckle structure to wrap the conductive sheets in the inner container assembly. Three insert sleeves of the same polarity are integrally formed, and the conductive sheets of the same polarity are located in the same horizontal layer. Only the conductive sheets and plastic partitions need to be stacked layer by layer to complete the installation of the inner container assembly, and the assembly efficiency is high (single finger inner container part). The overall volume of the product is small. However, the problem with this structure is that the plastic partitions are only fixed by the buckle, and the longitudinal structural strength of the inner container is not high. Even if the inner container is installed in the outer shell, it is still easy to deform and produce structural looseness under the action of external forces such as falling or collision.

[0005] In addition, the buckle structure does not help to improve the clamping strength of the socket. To prevent the plug from loosening, the national safety regulations have requirements for the plug-in force of the socket, and the plug-in force needs to be provided by the metal socket itself, and cannot rely on the plastic part. However, in order to provide better safety protection, prevent the metal socket from being fatigued after long-term use, and prevent the plug from loosening due to poor clamping, the common practice in the industry is to further clamp the socket by using the plastic parts arranged on both sides of the socket under the premise that the metal socket meets the regulations, and to limit the deformation of the socket after the plug is inserted. However, the existing magic cube socket multi-layer strong current structure plastic partition plate is only fixed by buckling, and when the plug is inserted or twisted, the socket limiting structure distributed on different partition plates cannot effectively limit the excessive deformation of the socket, and cannot play a clamping auxiliary role.
