The application of blister shell in life

A blister shell is a member that contains something or places something in it. In electrical products, the housing contains both uninsulated live electrical parts and insulated live electrical parts, and sometimes contains potentially dangerous moving parts. The shell protects against the risk of electric shock and injury by means of an insulator or mechanical interlayer between the shell itself and the internal components. For devices connected with flexible wires, the housing can also be used to reduce stress on the flexible wires. In other words, the housing helps prevent the cord from being pulled out of the product or pushed into the product.

Many electrical products use metal housing or molded blister housing. This category of electrical products includes small appliances, stationary and fixed large electrical equipment. Blister plate manufacturers feel that whether the product uses a metal shell or a blister shell, its test requirements are mostly the same, for example, shock voltage test. However, a series of relevant special factors should be taken into account when evaluating the blister housing, such as the flammability requirements for the blister housing, the requirements for the electrical and mechanical characteristics of the housing material, consideration of the impact of abnormal operation on the housing, and the replacement requirements for the housing material. When using the blister shell, be sure to understand its performance and use it safely.
