Background technique

The power socket is an electrical device that provides a power interface for electrical appliances. It is also an electrical accessory that is used more in residential electrical design. It has a very close relationship with people's lives. The socket whose position is fixed during use is called a fixed socket, and the one whose position can be moved freely according to needs is a mobile socket or a drag strip.

The hole shapes in the socket include two-hole hole type (socket hole for bipolar plug insertion), three-hole hole type (socket hole for three-pole plug insertion) and five-hole hole type (also known as universal socket hole, that is, at the same time A socket hole that can and can only be inserted by one of a double-pole plug and a three-pole plug). In order to meet the needs of inserting multiple plugs at the same time, a multi-position socket has been designed. The Chinese patent number is 2010206562334, the authorized announcement date is July 6, 2011, and the patent name is "a waterproof mobile socket with a protective door". A multi-position socket is disclosed in the literature. The existing five-hole hole type is set in a multi-position socket in such a way that the five-hole hole type electrode sleeves (5 in total) are fixed on the conductive sheet of the socket by welding, riveting or integral structure, and the socket sleeves are directly connected to each other. Positioning and fixing are carried out by the socket housing.

In order to improve the electrical safety of the socket, a safety door is usually set in the five-hole module.

A five-hole socket protection door is disclosed in the patent literature with the Chinese patent number 2010201880896, the date of authorization announcement being December 15, 2010, and the name "a protective door structure for five-hole sockets". The protective door of the five-hole socket includes a base, a pressure plate, a protective door, a return spring and a cover. One end of the return spring abuts against the cover, and the other end abuts against the protective door. A protective door is blocked in the five-hole socket at the same time. The sockets in the double-pole socket and the sockets (that is, five sockets) in the three-pole socket. Although the five-hole socket protection door in this patent has the advantage of sharing the return spring, it has the following defects: when one of the two sockets is opened, the other will also be opened at the same time, that is, there are two sockets that are opened at the same time. potential safety hazards (hereinafter referred to as simultaneous opening defects); the insertion of three-pole plugs with missing E poles cannot be restricted, and when the three-pole plugs are used when E poles are missing, it is impossible to achieve safe grounding of electrical appliances, thereby bringing safety Hidden dangers (hereinafter referred to as non-grounded insertable defects).

The five-hole plug-in protective door in the patent document adopts double return springs and double protective doors. It adopts the seesaw principle to avoid single-pole insertion, and the two protective doors work independently, thus overcoming the defect of simultaneous opening. But the second kind of five-hole plug-in protective door solves the defect of simultaneous opening and loses the advantage of sharing the return spring, and the defect that there is no ground pole that can be inserted still exists.

To sum up, the structure of the five-hole hole in the existing multi-position socket has the following deficiencies: it cannot be used universally among multi-position sockets with different layouts, which restricts the realization of automatic production of the socket; there is a defect that there is no ground pole and can be inserted .

The part 584 of the L pole inserting sleeve cannot move away from the second L pole clip 582 .

The side of the N-pole substrate 52 facing the N-pole substrate abuts against the side wall of the first accommodating chamber 511, that is, the N-pole substrate constitutes the first N-pole when the plug is inserted from the first N-pole socket 421 The position 523 of the socket cannot move away from the first N-pole clip 521, and the position 524 of the N-pole substrate that constitutes the second N-pole socket cannot move away from the second N-pole socket 411 when the plug is inserted. The direction of the second N-pole clip 522 moves.

Embodiment 3 is different from Embodiment 1 in that: the five-hole module cover plate is provided with a five-hole module panel on the side away from the five-hole module bottom box. An annular limit step is formed between the panel of the five-hole module and the cover plate of the five-hole module, which surrounds the outer periphery of the module panel of the five-hole module. Correspondingly, a five-hole module window that only passes through the five-hole module panel is directly arranged on the socket panel matched with the present invention. When in use, the five-hole module cover plate is aligned with the five-hole module window, and the limit step abuts against the inner surface of the socket panel, and is fixed by the hook in the socket panel.
