Bipolar socket protection door

Abstract

The invention discloses a bipolar socket protection door, which comprises a cover plate, a pressure plate, a first spring, a second spring, a first door and a second door, wherein the first door is provided with a first bevel door leaf and a second plane door leaf; the second door is provided with a second bevel door leaf and a second plane door leaf; the first and second doors are arranged in a staggered way; the first bevel door leaf and the second plane door leaf are superposed; the second bevel door leaf and the first plane door leaf are superposed; and the first and second doors can slide along a guide direction respectively and are not linked. The novel bipolar socket protection door in the invention has the advantages of very high safety grade and very high use reliability.

Description

technical field [0001] The invention relates to an electrical accessory, in particular to an industrial and civil building socket, in particular to a two-pole socket protection door. Background technique [0002] Power sockets are low-voltage electrical appliances widely used in industry and construction, including fixed sockets and movable sockets. According to the national electrical standard, the socket installed at a height of less than 1.8 meters should use a protective door to prevent non-plug objects from being inserted into the socket normally or contacting the electrodes, which may cause leakage accidents. electric shock when plugged into an outlet. Starting from the requirement of 1.8 meters below the national standard, most power sockets must have protective doors. These sockets include industrial electrical sockets that are fixedly installed in equipment or facilities, building electrical sockets that are fixedly installed on the wall, and used for various Remo...

Problems solved by technology

However, when the plug is forcibly inserted into the jack of the socket, the safety baffle can be forced to open so that the plug is normally inserted into the jack and contacts the electrodes in the jack. This safety baffle structure is very unreliable and brings Here comes the following problem: When a child is playing and inserts a conductive object into the jack forcibly, the safety baffle will also be forced to open, and the non-plug conductive object can still be easily inserted into the jack and make contact with the electrodes in the jack, which will still cause security incident

Obviously, no matter it is a single-layer protective door composed of single door, double door or multiple doors, there are the following serious defects: firstly, the safety protection function is still unsatisfactory, or its safety protection level is still low. ; Secondly, the realization of the single-insert safety protection function must be realized through a single seesaw structure of the mobile door and a cover plate blocking structure. That is, when one end of the movable door is subjected to the insertion pressure of the single plug, the other end of the movable door will tilt up. The so-called cover plate blocking structure refers to the raised end of the movable door that is set on the cover plate under the condition of single plug. Blocking, through which the movement of the moving door is restricted, so that the single-plug insert cannot be smoothly inserted into the jack, so as to avoid non-plug objects from contacting the electrodes in the jack

In order to ensure the reliability of use, it is necessary to adjust the coordination of the cover plate, the movable door and the base during assembly. As we all know, debugging the coordination of the three is much more difficult than debugging the coordination of the two, and it is time-consuming, which is not conducive to improving production efficiency.

In actual production, due to the difficulty of controlling the shape and position error during part processing and the difficulty of installation and debugging, the reliability of the use of this type of product is often not guaranteed, which brings defects of poor performance and inconvenient use to the product.
