Abstract
The utility model relates to a three-layer composite electrical contact. The three-layer composite electrical contact comprises a contact body and a contact connection pipe. The three-layer composite electrical contact is characterized in that the head portion of the contact connection pipe is provided with a layer of first silver-plated layer, and the contact surface of the contact body is provided with a layer of second silver-plated layer. The contact body and the contact connection pipe are made from copper. By adopting the technical scheme of the utility model, silver-plated layers having the advantage of better electrical conductivity are added on the base of an original structure, so the electrical conductivity of the electrical contact itself can be improved, and the production cost can be reduced compared with the situation that the whole electrical contact is made from silver.
Description
Technical field
The utility model relates to a kind of electric contact, especially a kind of three-layered composite electric contact.
Background technology
Present electric contact on the market all is to be made of contact bodies and contact tube connector, and its material all is to adopt copper, but the electric conductivity of copper itself is general, can not satisfy the environment of ask for something high conduction performance.
Summary of the invention
The purpose of this utility model is, provides a kind of electric conductivity high three-layered composite electric contact.
The technical scheme that the technical problem that proposes in the utility model solution background technology adopts is:
A kind of three-layered composite electric contact comprises contact bodies and contact tube connector, it is characterized in that: described contact tube connector head is provided with one deck the first silver coating, and the contact-making surface of described contact bodies is provided with one deck the second silver coating.
Described contact bodies and contact tube connector are made of copper.
After adopting the technical solution of the utility model: on original architecture basics, increase the better silver coating of electric conductivity, improved the electric conductivity of electric contact itself, and will save production cost than adopting silver to make fully.
