Abstract
The utility model relates to an electric contact group of a magnetic latching relay, which comprises a moving contact and a fixed contact. The electric contact group is characterized in that the contacting face of the moving contact is provided with a first round table; the contacting face of the fixed contact is provided with a second round table; the outer surface of the first round table is an arc surface; and the outer surface of the second round table is planar. After adopting the above-mentioned technical scheme, the electric contact group which has the two round tables contact each other can prevent the moving contact and the fixed contact from contacting each other in an edge copper leakage condition by designing a gap space.
Description
Technical field
The utility model relates to a kind of electric contact, especially a kind of electric contact group of magnetic latching relay.
Background technology
The contact of magnetic latching relay on the market,, in the situation that the edge leaks copper, its sound contact contact can cause arcing to heat up.
Summary of the invention
The purpose of this utility model is, a kind of electric contact group that prevents the magnetic latching relay of arcing phenomenon is provided.
The technical scheme that the technical problem that proposes in the utility model solution background technology adopts is:
A kind of electric contact group of magnetic latching relay comprises moving contact and fixed contact, it is characterized in that: the contact-making surface of described moving contact is provided with the first round platform, and the contact-making surface of fixed contact is provided with the second round platform, and the outer surface of described the first round platform is arc surface.
The outer surface of described the second round platform is the plane.
After adopting the technical solution of the utility model: two round platform contacts are arranged, by the design pitch space, can prevent in the situation that the edge leaks copper.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model is a kind of electric contact group of magnetic latching relay, comprise moving contact 1 and fixed contact 2, the contact-making surface of moving contact 1 is provided with the first round platform 3, the contact-making surface of fixed contact 2 is provided with the second round platform 4, the outer surface of described the first round platform 3 is arc surface, and the outer surface of the second round platform 4 is the plane.
Shown by above-mentioned structure, the beneficial effects of the utility model are: two round platform contacts are arranged, by the design pitch space, can prevent in the situation that the edge leaks copper, its sound contact contact causes arcing to heat up, and affects properties of product.
