Problems solved by technology

[0002] The traditional plug-in box is connected to the bus duct by two pieces of plug-in connection. It needs to provide a large clamping force to ensure the reliability of the plug-in contact. The greater the clamping force, the greater the resistance during the installation process. The more difficult it is, under the restrictions of some construction occasions, the user's operation is inconvenient, and it is difficult to perform reliable installation

Abstract

The invention discloses a plug-in box pin pressing and interlocking device which comprises a plug-in box body which is provided with a a box body back plate facing a bus duct and a door cover arrangedopposite to the box body back plate; an elastic pin which is movably arranged in the plug-in box body, wherein the end part of the elastic pin extends from the box body back plate to the outside of the plug-in box body to be connected with the bus duct; and a plug-in interlocking assembly which can selectively press the elastic pin against the bus duct, wherein the end part away from the elasticpin hinders the closure of the door cover when the plug-in interlocking assembly does not press the elastic pin. The plug-in interlocking assembly is used for applying preset pressure to the elastic pin, thereby ensuring effective contact between the elastic pin and the bus duct and ensuring electrical connection performance.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a pin pressing interlocking device of a plug box. Background technique [0002] The traditional plug-in box is connected to the bus duct by two pieces of plug-in connection. It needs to provide a large clamping force to ensure the reliability of the plug-in contact. The greater the clamping force, the greater the resistance during the installation process. The more difficult it is, the more inconvenient the user's operation is under the restrictions of certain construction occasions, and it is difficult to perform reliable installation. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a plug-in box pin pressing interlocking device, which implements the pre-tightening force of plug-in and contact through two parts, and the user does not need to make a strong plug-in during the plug-in process After the insertion is completed,...
