Anti-icing, anti-adhesion and anti-oxidation relay with inclined surface

Abstract

The invention discloses an anti-icing, anti-adhesion and anti-oxidation relay with an inclined surface. The relay comprises a shell, a static contact arranged in an insulating seat at the bottom of the shell, an annular supporting limiting seat fixed to the upper part of the insulating seat, a movable contact rod penetrating through the axis of the annular supporting limiting seat, a movable contact piece arranged at the lower end of the movable contact rod, a sleeve arranged on the periphery of the upper portion of the annular support limiting seat in a sleeving mode, an electromagnetic coilarranged between the sleeve and the shell, and a movable iron core arranged in the sleeve and supported at the top of the annular supporting limiting seat by a supporting spring; an ice shovel with adirection opposite to an inclination direction is arranged at the outer end of a split body of the movable contact piece; a stop hook bent downwards is arranged at the upper end of the ice shovel; aninclined surface is arranged at the upper portion of the static contact; an arc-shaped return seat arranged in a radial direction is arranged on the lower surface of the annular supporting limiting seat; and the bottom surface of the arc-shaped return seat is provided with a guide inclined surface for returning the ice shovel. According to the relay, ice frozen on the top surface of the static contact can be removed; adhesion and oxidation phenomena are prevented; the operation reliability of the relay is ensured; and the service life of the relay is prolonged.

Description

technical field [0001] The invention relates to a vehicle relay, in particular to an anti-icing, anti-adhesion and anti-oxidation relay with an inclined surface. Background technique [0002] With the increasing sales of new energy vehicles and the increasing number of models, more and more high-power relays are used in electric vehicles. The traditional automotive high-power relay consists of a housing, an insulating seat located at the bottom of the housing, two static contacts located in the insulating seat, an annular support limit seat fixed above the insulating seat, and a circular support limit seat that passes through the The moving contact rod in the center, the moving contact piece fixed at the lower end of the moving contact rod and forming an angle of 90 degrees with the moving contact rod, the return spring arranged between the lower end of the moving contact rod and the bottom surface of the insulating seat, set in the ring The sleeve supporting the outer peri...

AI Technical Summary

Problems solved by technology

However, the relay has the following problems: the electrical components of the vehicle are often tested by changes in the external temperature

This patent not only solves the problem of icing of static contacts, but also introduces new problems such as complex overall structure and unreliable action.

At present, there is no mechanism that can avoid the problems of icing, adhesion and oxidation of relay contacts, and can work reliably and with a long life
