Description

Protective door assembly

Technical Field

The utility model discloses relate to the shutter field generally, particularly to a shutter subassembly.

Background

The protective door is used for preventing the structure protected by the protective door from being exposed to the outside, so that danger, misoperation, dirtying and the like can be avoided. For example, the protective door of the socket can be used for avoiding power utilization accidents caused by misoperation or accidents, and can also prevent children from inserting fingers into the jacks to cause electric shock accidents. Therefore, safety and reliability of the protection door are very important.

For example, in modern life, with the importance of people on electricity safety, sockets with protective doors are more popular, and new national standards further require that the sockets need to be provided with the protective doors.

The existing socket protective door is mostly in a seesaw structure in the principle of structural design, namely two (positive and negative) holes of the protective door are pressed simultaneously to keep the whole protective door balanced, and the protective door can move in parallel, so that positive and negative metal elastic pieces of a power supply are exposed, and positive and negative plug pins of a plug are normally contacted with the positive and negative metal elastic pieces to be electrified. If the foreign matter is inserted into only one hole, the unbalanced stress can cause the protective door of the jack on the other side to tilt and hang at a certain position of the structure due to the seesaw principle, so that the protective door is limited in movement and cannot move in parallel, and the positive and negative electrode metal elastic sheets of the power supply cannot be exposed, thereby preventing abnormal insertion which is not required and playing a role in protection.

The protective door using the seesaw principle is simple in structural design and easy to realize in principle, but is poor in structural reliability and prone to deformation and failure in actual production, the seesaw structure needs to be well matched, the production precision requirement is high, and therefore the yield of the protective door using the seesaw principle in actual production is low.

Therefore, in view of the above technical problems, it is necessary to provide a new protective door assembly.
