Problems solved by technology

[0004] However, the copper filings generated when the dynamic and static contacts are disconnected will sputter to the side wall of the insulating cover of the relay. After the copper filings touch the side wall of the insulating cover, they will rebound and hit the lower end of the return force spring. Because the copper filings have high energy, The lower end of the return force spring will be melted and damaged, reducing the service life of the return force spring, making the reliability of the relay poor and the service life short

Abstract

The invention discloses a high-voltage relay. The high-voltage relay comprises a yoke, a static contact assembly and a moving contact assembly, wherein the static contact assembly and the moving contact assembly are arranged on the yoke. The static contact assembly comprises lead-out ends and static contacts. The moving contact assembly comprises moving spring sheets and moving contacts. The moving spring sheets are fixed with the upper end of a pushing rod. The lower end of the pushing rod is arranged below the yoke. An insulation cover is arranged on the upper side of the yoke. The insulation cover cooperates with the yoke to form a chamber for accommodating the moving contact assembly and static contact assembly. The insulation cover comprises a top plate and an enclosure part. The top plate is used for fixing the static contact assembly. An upwards extending protection projection is formed on the yoke. The cross section, in the radial direction of the pushing rod, of the protection projection is of an enclosure structure. The pushing rod is arranged on the inner side of the protection projection.

Description

technical field [0001] The invention relates to a high voltage relay. Background technique [0002] When the relay is assembled, some debris will be generated. When the relay is in use, the moving and static contacts will break and some copper scraps will be generated. These debris are sealed in the cavity formed by the insulating cover and the yoke iron, and the debris will move to the push rod and the yoke In the gap between the irons, the push rod is blocked when it moves up and down, and even the push rod is stuck, so that the dynamic and static contacts cannot be contacted or broken in time, which affects the use effect of the relay. [0003] In the high-voltage relay, the moving iron core will drive the push rod to move up and down, so that the moving contact on the moving reed fixed on the upper end of the push rod will contact or separate from the static contact. In the prior art, the push rod is only guided in the axial direction, but there is no limit in the circu...
