Special-shaped I-shaped copper bar and processing method thereof

Abstract

The invention discloses a special-shaped I-shaped copper bar and a processing method thereof. The special-shaped I-shaped copper bar comprises a first I-shaped copper bar body, the first I-shaped copper bar body comprises an upper copper plate, a supporting plate is fixedly connected to the middle of the bottom surface of the upper copper plate, a lower copper plate is fixedly connected to the bottom end of the supporting plate, and the upper copper plate and the lower copper plate are vertically aligned; the edge of one side of the surface of the top of the upper copper plate is fixedly connected with a second I-shaped copper bar through two additional mechanisms, the middles of the surfaces of the two sides of the supporting plate are fixedly connected with reinforcing ribs, and the surface of the top of the upper copper plate is electroplated with a tin layer. The special-shaped I-shaped copper bar is composed of an upper copper plate, a supporting plate and a lower copper plate, the first I-shaped copper bar and the second I-shaped copper bar are additionally arranged through the additionally-arranged mechanism, according to the additionally-arranged mechanism, a hand-screwed stud penetrates through a penetrating hole in a connecting piece and then penetrates through penetrating holes in the surfaces of the tops of the two I-shaped copper bars to be connected together, and the two I-shaped copper bars are fastened through a nut, so that the additionally-arranged fastening effect is better, and the situation of deformation cannot occur in the additionally-arranged process.

Description

technical field [0001] The invention relates to the technical field of copper components, in particular to a special-shaped H-shaped copper bar and a processing method thereof. Background technique [0002] Copper bar is a high-current conductive product, which is suitable for electrical engineering such as high and low voltage electrical appliances, switch contacts, power distribution equipment, bus ducts, etc. Copper bars have the advantages of low resistivity and large bendability, and special-shaped copper bars are copper bars whose cross-sectional shape is not rectangular and square, so as to meet the needs of electrical appliances of different shapes and sizes. The quality of special-shaped copper bars on the market is It is not good, and the method of adding copper plates is mostly to clamp the copper plates layer by layer. The fastening effect is not good, it is easy to be scattered during the assembly process, and it is easy to deform the copper bars due to misalign...
