Abstract
The invention discloses a contact point of an electric appliance. The contact point comprises a tungsten alloy plane, wherein a first notch opening and a second notch opening are arranged on the plane; the first notch opening and the second notch opening are crossed to be a crossing shape; and both ends of each notch opening extend to the edge of the plane. With the adoption of the contact point of the electric appliance, a cross-shaped notch is cut on the contact point tungsten alloy, and certain air flow is generated when two contact points are contacted and disconnected, so that the contact points can be cooled, the ablation is reduced, and the service life of the contact points is prolonged.
Description
Technical field
The present invention relates to a kind of parts for electrical equipment, relate in particular to a kind of appliance contact.
Background technology
The contact is in normal use procedure, can be because constantly connect and cut off electric current and produce electric arc, the electric arc contact of can ablating, but also the temperature of contact is raise, if the contact temperature heat radiation is bad, will further accelerate the ablation of contact and coming off of tungsten alloy.
Summary of the invention
The invention provides a kind of appliance contact, with coming off of the ablation that slows down the contact and tungsten alloy.
The technical solution used in the present invention is as follows:
A kind of appliance contact comprises the tungsten alloy plane, and the first notch and the second notch are set on this plane, and the first notch and the second notch intersect and be " cross " type, and the two ends of every notch all extend to the edge on plane;
Appliance contact of the present invention is cut cross groove on the tungsten alloy of contact, in order to allow two contacts contact and produce certain air-flow when disconnecting and allow well the contact cooling, reducing ablates increases the service life.
Description of drawings
Fig. 1 is the structural representation of appliance contact one embodiment of the present invention.
Fig. 2 is the structural representation of Fig. 1 one side.
Embodiment
As depicted in figs. 1 and 2, appliance contact of the present invention comprises tungsten alloy plane 1, the first notch 11 and the second notch 12, the first notches 11 and the second notch 12 is set on this plane intersects and be " cross " type, and the two ends of every notch all extend to the edge on plane.
Claims (1)
1. an appliance contact comprises the tungsten alloy plane, it is characterized in that on described plane the first notch and the second notch being set, and the first notch and the second notch intersect and be " cross " type, and the two ends of every notch all extend to the edge on described plane.
