Mounting clamp for switch moving contact

Abstract

The invention belongs to the field of a tooling clamp, in particular to a mounting clamp for a switch moving contact and used for a semi-insulating ring main unit. The mounting clamp comprises an upper clamp body and a lower clamp body, wherein the upper clamp body and the lower clamp body are connected with each other in a moving manner and have the same length L; a space compressing mechanism and a resetting mechanism are arranged between the upper clamp body and the lower clamp body; both ends of the space compressing mechanism are respectively connected with the upper clamp body and the lower clamp body; both ends of the resetting mechanism are respectively arranged in the upper clamp body and the lower clamp body; the horizontal distance D from the position of the space compressing mechanism to the connection position of the upper clamp body and the lower clamp body is greater than or equal to 0.5L; and the end of the upper clamp body is provided with a notch, the end of the lower clamp body is provided with a pit, and the notch and the pit are in the same line approximately in the vertical direction. By utilizing the invention, the problem of arranging a dished spring pad or other elastic components with high elasticity on a device similar to a latch is solved, the operation is convenient and quick, and the working efficiency is enhanced greatly.

Description

technical field [0001] The invention belongs to the field of tooling fixtures, in particular to a switch movable contact installation fixture for a semi-insulated ring network cabinet. Background technique [0002] The ring network cabinet is a group of high-voltage switchgear installed in the steel plate metal cabinet or made into an assembled spaced ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, low price, and Improve power supply parameters and performance and power supply security and other advantages. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. In order to improve the reliability of power supply and enable users to obtain power from two directions, the power supply network is usually connected into a ring. This power supply method is referred to as the ring ...

Problems solved by technology

Just because the elasticity of the disc spring pad is very strong, it is difficult to compress and clamp it with the circlip c in the actual assembly process. Sometimes it is clamped with pliers, but the effect is very poor, and it is easy to damage the disc spring. to the expected effect
