Abstract

The utility model discloses a split type insert for a bus bushing. The split type insert comprises an upper block and a lower block; the face-to-face ends of the upper block and the lower block are provided with strip-shaped grooves; a U-shaped cutting sleeve is arranged in each strip-shaped groove; the inner wall of the recess of each U-shaped cutting sleeve is provided with antiskid convex point arrays; and the opening of each U-shaped cutting sleeve extends to two sides to form ribs pressed on the corresponding end of the upper and lower block. According to the split type insert, the structure is simple and reasonable, installation and usage are convenient, the split type design is employed, U-shaped cutting sleeves are arranged on the upper and lower blocks, the stability after a bus bar is arranged is effectively raised, a loosening phenomenon is prevented after long-term use of the bus bar, and usage safety of the bus bushing is effectively guaranteed.

Description

The split type inserts of a kind of bus casing

Technical field

The utility model relates to a kind of electric fittings, is specially the split type inserts of a kind of bus casing.

Background technology

When installing in switch cubicle, need to use bus bus casing to be fixed, and existing bus casing structure is reasonable not, bus bar is not good at bus casing internal stability after installing, easily there is loosening phenomenon in the inserts after long-time use in bus bar and bus casing, cause the stability decreases of bus casing, and then affect the use safety of bus bar.

Utility model content

The purpose of this utility model is to provide the split type inserts of a kind of bus casing, reasonable not to solve bus casing structure traditional in prior art, bus bar is not good at bus casing internal stability after installing, easily there is loosening phenomenon in the inserts after long-time use in bus bar and bus casing, cause the stability decreases of bus casing, and then affect bus bar and use safe problem.

For achieving the above object, the technical solution adopted in the utility model is:

The split type inserts of a kind of bus casing, it is characterized in that: include fixture block and lower fixture block, the corresponding end of described upper fixture block and lower fixture block is provided with strip groove, U-shaped cutting ferrule is installed in described strip groove, on the recess inwall of described U-shaped cutting ferrule, be distributed with anti-skidding salient point array, the openend of described U-shaped cutting ferrule extends to form to both sides to press puts the rib in upper and lower fixture block corresponding end.

The described split type inserts of a kind of bus casing, is characterized in that: on described upper fixture block and lower fixture block, be equipped with a plurality of installing holes.

The beneficial effects of the utility model are:

The utility model is simple and reasonable, easy to install, adopts split-type design, and U-shaped cutting ferrule is installed on upper and lower fixture block, effectively improve the stability after bus bar is installed, avoided the long-time loosening phenomenon of rear generation of using of bus bar, effectively guaranteed the use safety of bus casing.
