1), the bent part is strongly supported by the bottom surface, and a certain pressure can be applied when mounting;

2), the bent portion increases the contact area between the pin and the circuit board, and the mounting is firm;

3), the seat body is well insulated from the circuit board, which plays a good role in insulation and protection.

In the mounting seat of the present invention, the seat body may be provided with inwardly extending recesses for fixing the associated electronic components.

In the mounting seat of the present invention, a cover body may be further provided, and the cover body of the mounting seat and the cover body of the mounting seat are preferably engaged with each other so as to collectively constitute a closed outer casing. Such a design can serve as a package protection.

In the mount of the present invention, the cover may also be provided with inwardly extending recesses for securing the associated electronic components. This design allows the installed electronic components to be constrained between the limit pits of the two for easy fixing.

In another aspect, another object of the present invention is to provide an electronic component with a mounting body, the electronic component comprising an electronic component body having a plurality of pins, wherein the electronic component body has a pin From top to bottom, the holes are bent through the corresponding pin holes, and the bent portions are not in contact with each other.

Preferably, the bent portions are supported by the bottom surface of the base. The mounting seat of the present invention can be used for any electronic component. Preferably, the pins of the body of the electronic component are bendable.

As a specific embodiment, in the present invention, the electronic component body is a varistor. The mounting seat of the invention has the advantages of simple structure and convenient use. The common electronic component is equipped with the mounting seat of the invention, and can be turned into an electronic component for easy mounting, and is suitable for various electronic components which can be bent. The electronic components of the mounting base are further described, but these specific embodiments are not intended to limit the invention. DRAWINGS
