The connector with the secondary lock catch comprises a plug, a socket and a lock catch structure, the plug is provided with an insertion cavity matched with the socket, the plug is provided with a first placement groove, the lock catch structure comprises a buckle, a pressing block and the secondary lock catch, the middle of the buckle is rotatably connected in the first placement groove, and the pressing block is arranged in the second placement groove. One end of the buckle is sleeved with a pressing block in a sliding mode, the pressing block and the first containing groove are clamped in a matched mode so as to lock the position of the buckle, the other end of the buckle is provided with a clamping groove, the socket is provided with a clamping block connected with the clamping groove in a clamped mode, one end of the secondary lock catch is connected to the socket in a rotating mode, and the other end of the secondary lock catch is connected to the socket in a rotating mode. And the other end of the secondary lock catch is clamped with two sides of one end of the buckle through a locking structure. The secondary lock catch structure is added on the plug and the socket, so that the problem that a buckle type connector is not inserted in place can be effectively solved, and the electric shock potential safety hazard caused by loosening of a high-voltage connector is avoided.

This invention relates to the field of power distribution cabinet technology and discloses a multi-channel heat dissipation power distribution cabinet for smart grids. It includes a cabinet body with supporting legs at the bottom, a perforated grille top cover at the top of the cabinet body, symmetrically mounted frames on the inner walls of the cabinet, and several copper busbar partitions arranged sequentially from top to bottom on the rear inner walls of the two frames. Layered panels are also symmetrically mounted vertically on the inner walls of the two frames, and a base plate is also mounted on the inner walls of the two frames. This multi-channel heat dissipation power distribution cabinet for smart grids effectively solves the problems in existing technologies where the heat dissipation channels of power distribution cabinets are mostly fixed and normally open, unable to flexibly switch between open and closed states according to environmental conditions. In low-temperature and high-humidity environments, cold and humid air from the outside easily enters the power distribution cabinet, causing condensation, leading to corrosion and short circuits of electrical components, and the inability to effectively balance the contradiction between dust prevention, waterproofing, and heat dissipation.

The present invention discloses a floor socket, comprising a base and a socket body rotatably arranged on one side of the base, wherein a static contact, a moving contact, a first elastic member, an operating mechanism, an interlocking mechanism and a power-off driving device are arranged in the socket body; the interlocking mechanism has a locking state in which the operating mechanism is linked to the moving contact, and an unlocking state in which the operating mechanism is disengaged from the moving contact; by linking the driving structure of the power-off driving device with the interlocking mechanism, the base pushes the driving structure when the socket body is closed to drive the interlocking mechanism to move from the locking state to the unlocking state, thereby realizing power-off isolation protection of the floor socket when it is not in use, and realizing rapid power-off protection by manually operating the power-off driving device when the floor socket is in use, so as to cope with emergencies, avoid leakage accidents and electric shock hazards to people, and the operation is convenient, practical, safe and reliable.
