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, and the relay comprises a yoke, a static contact assembly and a moving contact assembly, wherein the static contact assembly and the moving contact assembly are disposed above the yoke. The static contact assembly comprises a leading-out end and a static contact. The moving contact assembly comprises a moving contact spring and a moving contact, wherein the moving contact spring is fixed with the upper end of a push rod, and the lower end of the push rod is located below the yoke. The upper side of the yoke is provided with a positioning plate and an insulating cover. The insulating cover and the yoke are fixed to form a cavity for accommodating the moving contact assembly and the static contact assembly. The insulating cover comprises a top plate and an enclosing part. The top plate is used for fixing the static contact assembly, and the positioning plate is provided with a vertical positioning plate through hole so as to push the push rod to pass. A protection projection which extends upwards is formed on the positioning plate. The section of the protection projection along the radial direction of the push rod is of an enclosing structure, and the positioning plate through hole is located at an 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...
