Plum blossom-shaped contact installing tool and plum blossom-shaped contact propeller

Abstract

The invention discloses a plum blossom-shaped contact installing tool and a plum blossom-shaped contact propeller. The plum blossom-shaped contact propeller comprises a bottom plate and a pressing plate, wherein the pressing plate which moves up and down relative to the bottom plate is arranged above the bottom plate; an up-and-down guide moving mechanism is connected between the bottom plate and the pressing plate; a pushing surface for pushing a plum blossom-shaped contact is arranged on the lower surface of the pressing plate; and the upper surface of the bottom plate is provided with a positioning boss for positioning a contact arm, which is vertically opposite to the pushing surface of the pressing plate. According to the plum blossom-shaped contact propeller, the contact arm is positioned on the positioning boss on the bottom plate, a guide body in the prior art is placed on the contact arm, and then the plum blossom-shaped contact is placed on the guide body and is arranged on the contact arm after being pressed by the pressing plate; and during installation, the plum blossom-shaped contact is uniformly stressed, and contact fingers are difficult to stagger and scatter.

Description

technical field [0001] The invention relates to an installation tool for a tulip contact and a contact arm used on a VSI vacuum circuit breaker. Background technique [0002] The installation of the plum blossom contact used in electrical equipment is to first clamp the protruding parts arranged along the circumference of the rear end of the plum blossom contact in the annular groove at the front end of one contact arm, and insert the other contact arm directly from the front end during use. , to achieve conductive connection, the structure diagram of the plum blossom contact is attached figure 1 The schematic diagram of the structure of the contact arm is shown in the attached figure 2 As shown, the installation effect diagram of the plum blossom contact and the contact arm is as attached image 3 As shown, for the connection between the annular groove on the above-mentioned contact arm and the rear end of the plum blossom contact, traditionally, a guide body with a tape...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a plum-blossom contact pusher to solve the problem in the prior art that the contact fingers on the plum-blossom contacts are dislocated and scattered due to the uneven force of the plum-blossom contacts during the installation process. The purpose is also to provide a plum contact installation tool using the pusher
