Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of row plug, especially to a row plug shell. BACKGROUND

[0002] The traditional socket design usually adopts the mode that the upper cover and the lower cover are combined through screw locking, this structure can realize relatively firm connection, but in the assembly process, the locking process of the screw is relatively cumbersome, increases the assembly time, and the operation proficiency of the worker is required to be higher. In addition, the screw locking mode is convenient to disassemble, there is the risk of being disassembled or damaged by non-professionals, and the service life and safety of the socket are easily affected. Therefore, in the structural design of the socket, a more rapid, firm and not easy to disassemble connecting mode is needed to improve the production efficiency and ensure the safety and stability of the technical state of the socket in use.

[0003] For the adaptability of various installation scenes, the traditional socket design also has certain limitations. The traditional socket usually only has a structure for fixing on the wall, such as a hook or a hanging hole, etc. at one end of the shell. Although this structure can provide basic fixing function, due to the fewer fixing points, it is often difficult to ensure the stability of the socket in use. When the row plug is installed on the wall surface of different materials (such as foam wall, wooden wall, etc.), if no additional shell drilling, expansion pipe and screw are used, it is often difficult to realize reliable fixation, resulting in unfirm installation and even safety hazards. In addition, the exposed screw around the installation hole of the socket also affects the overall aesthetics of the socket and reduces the user experience.

[0004] In the prior art, the alternating current circuit and the direct current circuit board of the socket are usually not completely isolated, which may cause interference of alternating current electromagnetic radiation on the direct current circuit board, affecting the normal use performance of the socket. At the same time, in the alternating current part, the welding points of the wire harness and the copper bar of the traditional socket are easy to be affected by metal fatigue, and the pulling and rotation in daily use may cause damage to the welding points, thereby affecting the current carrying capacity, and even causing the risk of short circuit.
