Abstract

The utility model belongs to a low voltage power transmission and distribution device, and relates to a drawer cabinet primary contact head for a low voltage drawer type switch cabinet. The drawer cabinet primary contact head is composed of two contact pieces symmetrically arranged side by side and a spring piece; the middle sections of the two contact pieces protrude inwardly and are in contact with each other, so that each contact piece forms a lever structure with a supporting point where the contact occurs; the front sections of the two contact pieces stretch outwardly and are curved; an arched outer surface is formed on the outer side at the front section of the contact piece, and is taken as a working surface where the conduction contact with a vertical conductive bar by the two contact pieces occurs; the rear sections of the two contact pieces are straight; and the spring piece with a C-shaped section is clamped on the outer side at the rear sections of the two contract pieces, so that the rear sections of the two contact pieces can approach mutually. The utility model has the advantages of simple structure and convenient manufacture and installation. By utilizing the lever structure, the utility model ensures that the conductive contact part always has good elasticity, and the contact point has enough contact pressure, thereby ensuring the reliability of conductive contact.

Description

The drawout cubicle one-time contact

Technical field

The utility model belongs to the low pressure equipment for power transmission and distribution, relates to a kind of drawout cubicle one-time contact that is used for low pressure drawer-type switch cabinet.

Background technology

One-time contact in the low-voltage drawer cabinet is to be used for arranging the conductive component that is conductively connected and touches with vertical conduction, the vertical conduction row that existing a kind of cross sectional shape is a C shape, it is compared with the busbar of traditional square-section and can improve current capacity and reduce temperature rise, but for the one-time contact that is conductively connected with it and touches, structural design is brought certain difficulty, existingly be used for conducting electricity the one-time contact that is connected and exist complex structure mostly, make defectives such as the reliability of inconvenience being installed, contacting is low with C tee section vertical conduction row.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of simple in structure, easily manufactured, reliable drawout cubicle one-time contact of conduction contact is provided.

Drawout cubicle one-time contact of the present utility model is made up of two symmetrically arranged side by side contacts and a spring leaf, and the stage casing of described two contacts is to inner process and be in contact with one another, and making each contact constitute with the contact point is the lever construction of fulcrum; The leading portion of two contacts outwards opens, and is bending, forms the outer surface that arches upward in the outside of contact leading portion, as arranging the working surface that is conductively connected and touches with vertical conduction; The back segment of two contacts is a linear, and the c-shaped spring leaf in cross section is clamped in the outside of two contact back segments, makes two contact back segments close mutually.

The outwards bending of edge of opening part of the spring leaf of described C tee section forms guiding surface toward the outer side.

The utility model is simple in structure, manufacturing and easy for installation, and it utilizes lever construction to make conduction contact part keep better elastic, makes the contact have enough contact pressures, has guaranteed the reliability of conduction contact.

Embodiment

As shown in the figure, this drawout cubicle one-time contact is made up of two symmetrically arranged side by side contacts 1 and the c-shaped spring leaf 2 in cross section.The stage casing of two contacts is to inner process and be in contact with one another, and making each contact constitute with contact point 0 is the lever construction of fulcrum; The leading portion of two contacts outwards opens, and is bending, forms the outer surface 11 that arches upward in the outside of contact leading portion, the working surface (referring to Fig. 4) that this outer surface contacts as conduction when being connected with vertical conduction row 3; The c-shaped spring leaf 2 in cross section is clamped in the two contact back segments outside, and spring force makes two contact back segments close mutually, and the outwards bending of edge of opening part of spring leaf forms guiding surface 21, so that with contact on the spring pressure.
