Embodiment Construction

[0020] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as Figure 1 to Figure 5 A plug for switching appliances shown, including a contact connecting plate 1 and a leaf spring 5 for forming a conductive circuit, a bracket 3 for installing the contact connecting plate 1 and a mounting plate for installing the leaf spring 5 4. The bracket 3 is a plastic part, comprising two horizontal plates 31 arranged in parallel and two vertical plates 32 arranged in parallel, and a plurality of installation holes 33 are evenly spaced on the vertical plates 32 . There are two contact connecting plates 1, both of which are made of copper and plated with silver. The contact connecting plate 1 is stamped from a copper plate, and a plurality of compartments 14 are evenly spaced on both sides of the contact connecting plate 1. , forming a plurality of connecting pieces 13, thereby forming a...

Abstract

The invention relates to a plug for a switching device. The plug comprises two contact-use connection pieces, elastic pieces, a support and mounting plates, wherein the two contact-use connection pieces and the elastic pieces are used for forming a conducting loop, the support is used for mounting the two contact-use connection pieces, and the mounting plates are used for mounting the elastic pieces. The two contact-use connection pieces are arranged on the two sides of the support respectively, and the elastic pieces abut against the contact-use connection pieces and exert certain pressure on the contact-use connection pieces; the inner surfaces of the two sides of the two contact-use connection pieces form a first contact face in contact with a drawer seat busbar and second contact face in contact with a body busbar. When the plug is plugged in, the first contact face and the second contact face are in contact with the drawer seat busbar and the body busbar respectively, breakover of a circuit is achieved, the current is borne, the main function of a switch is achieved, when the current flows across the switching device, electric power is overcome through pressure of the elastic pieces on the contact-use connection pieces, and a power system can operate safely and effectively.

Description

technical field [0001] The invention belongs to the technical field of electrical appliances, in particular to a plug for switching electrical appliances. Background technique [0002] Switching appliances are devices used in power distribution systems to switch on and off loads and protect the safety of lines and equipment. [0003] The drawer-type switching device in the prior art is used for the electrical connection system between the main body and the drawer seat to carry current. The same multi-piece copper contact plate is installed as a bridge-shaped contact. The amount of copper used is large and the cost is high. The spring needs to be installed with a special fixture, and the workmanship is poor. [0004] Therefore, it is an urgent need in actual production to seek an electrical connection system with small size, low cost, and easy installation to solve the defects in the production of previous products. Contents of the invention [0005] In order to solve the...
