Abstract
The utility model relates to a tin-coated copper bar, which belongs to the technology field of electric alloy materials. The tin-coated copper bar includes a copper bar body (1) comprising two portions of an upper portion and a lower portion, wherein the lower portion possesses a rectangular shape (11), the upper portion possesses an inclined edge (12), the included angle at the intersection of the rectangular shape (11) and the inclined edge (12) is an acute angle, and the intersection of the rectangular shape (11) and the inclined edge (12) employs an arc for transition. Thereby the tin-coated copper bar is suitable for an occasion having a special requirement on the cross section shape of a conductor material. The requirement of product updating in electric appliance industry is satisfied. The surface of the copper bar body (1) is coated by a layer of metallic tin (2), which can enhance the conductive performance of the copper bar.
Description
Technical field
The utility model relates to a kind of electrician and uses copper bar.Be mainly used in mesolow switch cubicle, bus-bar system, transformer, railway, wind-force, nuclear power and hydroelectric generator etc.Belong to electrical alloy material technology field.
Background technology
The electrician is to make installations such as mesolow switch cubicle, bus-bar system, transformer, railway, wind-force, nuclear power and hydroelectric generator to use conductor material with copper bar.Traditional electrician is not enough below existing with copper bar:
1, its cross section is rectangular.Rectangular copper bar can only be satisfied with general electric equipment products and make conductor material, has the occasion of special cross-section shape need then can not be suitable for for some to conductor material.Thereby satisfied not the demand of the electrical apparatus industry updating and upgrading of a product.
2, copper bar is processed by fine copper, its electric conductivity a little less than.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and can be applicable to the zinc-plated copper bar that conductor material is had the occasion of special cross-section shape need and conducts electricity very well.
The purpose of the utility model is achieved in that a kind of zinc-plated copper bar; Comprise the copper bar body, said copper bar body cross-section is abnormally-structured greatly, is made up of two parts up and down; Its lower middle portion is a rectangle; Top is divided into a hypotenuse, and said rectangle and hypotenuse intersection angle be acute angle, and arc transition is adopted in rectangle and hypotenuse intersection.And be coated with layer of metal tin on the surface of said copper bar body.
The beneficial effect of the utility model is:
1, the employing of the cross section of the utility model copper bar is abnormally-structured greatly, therefore can be applicable to the occasion that conductor material is had the special cross-section shape need, has satisfied the demand of the electrical apparatus industry updating and upgrading of a product.
2, owing to be coated with layer of metal tin, can increase the electric conductivity of copper bar on the surface of copper bar.
Description of drawings
Fig. 1 is the cross-sectional structure sketch map of the zinc-plated copper bar of the utility model.
Reference numeral among the figure:
Copper bar body 1, rectangle 11, hypotenuse 12;
Metallic tin 2.
Embodiment
Referring to Fig. 1, Fig. 1 is the cross-sectional structure sketch map of the zinc-plated copper bar of the utility model.Can find out that by Fig. 1 the zinc-plated copper bar of the utility model comprises copper bar body 1; Said copper bar body 1 cross section is abnormally-structured greatly; Be made up of two parts up and down, its lower middle portion is a rectangle 11, and top is divided into a hypotenuse 12; And said rectangle 11 is an acute angle with hypotenuse 12 intersection angles, and rectangle 11 adopts arc transition with hypotenuse 12 intersections.And be coated with layer of metal tin 2 on the surface of said copper bar body 1.
Claims (1)
1. zinc-plated copper bar; Comprise copper bar body (1), it is characterized in that said copper bar body (1) is made up of two parts up and down, its lower middle portion is a rectangle (11); Top is divided into a hypotenuse (12); And said rectangle (11) is an acute angle with hypotenuse (12) intersection angle, and rectangle (11) adopts arc transition with hypotenuse (12) intersection, and is coated with layer of metal tin (2) on the surface of said copper bar body (1).
