Safety door structure of power socket

Abstract

The invention relates to a safety door structure of a power socket. The safety door structure of the power socket comprises a socket shell body, a safety baffle, a safety door base and a reset bias piece. The safety baffle is of an integral structure and comprises a baffle body part and cover sheet parts located on the left side and the right side of the baffle body part respectively, the cover sheet parts comprise two-pin jack cover sheets arranged on the left side and the right side, upper three-pin jack cover sheets on the left side and the right side and lower three-pin jack cover sheets on the left side and the right side, the safety baffle is arranged on the safety door base and is used for covering two-pin jacks and three-pin jacks, and the reset bias piece is used for achieving the sliding of the safety baffle. The safety door structure of the power socket solves the problem that another pole jack is exposed after a two-pole plug or a three-pole plug is inserted into a five-hole socket, therefore, the safety of the socket is ensured, and accidental electric shocks can be prevented effectively.

Description

technical field [0001] The invention belongs to the electrical connection field of power supply equipment, in particular to a power socket safety door structure. Background technique [0002] The power socket is an electrical device that provides a power interface for household 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. Low-quality power sockets often cause personal electric shocks and electrical fires. Personal and property safety brings major hidden dangers, so the design of power sockets is also an important basis for evaluating residential electrical design. [0003] In order to realize the safe use of the socket, many power sockets are equipped with a safety door, also called a protective door, which is usually an insulator above the socket assembly. After the plug is inserted, the position of the insulator moves to make the power switch on. After the plug is pu...

Problems solved by technology

For the five-hole socket combined with two-prong and three-prong jacks, corresponding safety standards are also required. However, in the current use process, when using two-prong jacks or three-prong jacks, the other party will be exposed, which is easy Splashing into water, or accidental contact with live sockets will pose a safety hazard, which will reduce the safety performance of the socket. Chinese patent document 202373747U discloses an improved structure for the protection door of a five-hole socket, including a two-hole socket and a three-hole socket. The protective cover of the jack, the protective cover is provided with a two-hole protective door covering the two-hole jack and a two-hole protective door covering the three-hole jack; the two ends of the two-hole protective door pass through the protective door spring I and The top side of the protective cover is offset, and the middle part of the three-hole protective door is offset against the bottom side of the protective cover through the protective door spring II; the upper end of the three-hole protective door is provided with a guide column slidingly connected with the second-hole protective door to cover the three-hole socket. There is a limit block between the two-hole protection door and the three-hole protection door, but in this structure, since the two-hole protection door and the three-hole protection door are two separate and independent parts, they need to be designed separately In addition, it is necessary to configure three return springs to realize the reset of the two-hole protection door and the three-hole protection door. Therefore, the structure has many components, which is not only complicated and troublesome to assemble, but also has high production costs, which is not conducive to cost reduction.
