Torx contact spring installation device

Abstract

The invention discloses a plum blossom contact spring installation apparatus, which comprises a power apparatus, at least one retainer ring and at least two bar-shaped fins; the bar-shaped fins are installed at the periphery of the retainer ring and are in cooperation with the retainer ring to form a deformation cylinder sleeved by springs. The power apparatus drives each bar-shaped fin to get close to or be far from the central axis of the deformation cylinder at the same time. Only one person is needed to install the springs on the plum blossom contact, and the complex procedure of butt joint by two or more persons during spring installation in the prior art is avoided, thereby raising the efficiency of assembling the springs on the plum blossom contact. At the same time, phenomena like plum blossom contact deformation or scratch heating because of replacement carried out by a screwdriver or the hands are avoided, therefore, the circuit equipment usage safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of assembly tools for electric equipment, in particular to a plum blossom contact spring installation device. Background technique [0002] The plum blossom contact is a commonly used conductive sliding connection part, which is installed on other handcarts such as switch handcarts, fuse handcarts and isolation handcarts. attached figure 1 Shown is a three-dimensional schematic diagram of the tulip contact 100 , which includes a tulip contact finger 110 and several springs 120 installed on the tulip contact finger 110 . Wherein, whether the pressure of the spring 120 in use is normal or not is directly related to the safe operation of the electric equipment. Under long-term use, the spring is prone to fatigue and loosening, which affects the safe and stable operation of the equipment. Therefore, the spring must be replaced regularly. At present, the replacement method of the spring is that the staff use ...

AI Technical Summary

Problems solved by technology

At present, the replacement method of the spring is that the staff use a screwdriver or hand to replace it, which will easily deform the plum blossom contact finger 110 or scratch and generate heat; If the spring is not strong, it will easily cause the spring to bounce and hurt the staff, and if the installation is not good or not in place, it will easily cause poor contact between the contacts and the switch; this installation method takes a long time and the installation efficiency is not high
