Description

A square silver contact

technical field

The utility model relates to electronic components, in particular to a square silver contact used for a power switch.

Background technique

Electrical components are indispensable products in people's daily life, especially the power switch, which plays a protective role for the circuit. The contact surfaces of the silver contacts used in the existing power switches are all round and single in shape. When installing the silver contacts, sometimes the disadvantage that the interface for installing components is not wide enough to install the silver contacts may be encountered.

Utility model content

The purpose of this utility model is to provide a square silver contact for a power switch in view of the above-mentioned defects of the prior art.

In order to solve the above-mentioned deficiencies of the prior art, the technical solution to be solved by the utility model is: a square silver contact, comprising a cylinder, one end of the cylinder is provided with a square connecting plate, the other of the square connecting plate One side is covered with a contact layer.

As an improvement of the square silver contact of the utility model, the contact layer is a silver component. Silver components have the characteristics of low melting point. When the circuit is short-circuited, the silver contacts in the power switch will be automatically fused by heat, which will protect the electrical appliances.

As an improvement of the square silver contact of the utility model, the cylinder and the square connecting plate are copper components. The copper component has the advantages of low price, durability and wear resistance, which is beneficial to the long-term use of the power switch.

As an improvement of the square silver contact of the utility model, the thickness of the contact layer is selected in the following range: 0.1mm-0.5mm. The thickness of the contact layer can be selected according to the size of the power switch to avoid wasting resources.

As an improvement of the square silver contact of the utility model, the thickness of the contact layer is 0.2 mm.

Compared with the prior art, the utility model has the advantages that: the utility model adopts a square silver contact, which avoids the disadvantage that the interface of the existing circular silver contact is not wide enough to install the silver contact.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

Below just will further describe the utility model according to accompanying drawing.

As shown in FIG. 1 , a square silver contact includes a cylinder 1 , one end of the cylinder 1 is provided with a square connection plate 2 , and the other side of the square connection plate 2 is covered with a layer of contact layer 3 .

The contact layer 3 is a silver member. Silver components have the characteristics of low melting point. When the circuit is short-circuited, the silver contacts in the power switch are automatically fused by heat, which protects the electrical appliances.

Both the cylinder 1 and the square connecting plate 2 are copper components. The copper component has the advantages of low price, durability and wear resistance, which is beneficial to the long-term use of the power switch.

The thickness of the contact layer 3 can be selected in the following range: 0.1mm-0.5mm. The thickness of the contact layer 3 can be selected according to the size of the power switch to avoid wasting resources.

The utility model adopts a contact layer 3 with a thickness of 0.2 mm, which is suitable for silver contacts of most power switches, which can protect power devices and save costs.

It should be noted that, according to the disclosure and teaching of the above specification, those skilled in the art to which the present invention pertains may also make changes and modifications to the above implementation manner. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some equivalent modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
