Description

A kind of conducting copper

Technical field

This utility model relates to conductive connecting device technical field, is specifically related to a kind of conducting copper.

Background technology

Copper bar is also called copper bus-bar or copper bus-bar, belongs to a kind of conducting heavy current product, have resistivity low, can bending The advantages such as degree is big, are mainly used in the field such as middle-low voltage switch cabinet, transformator.Existing copper bar is typically all cuboid tabular, only General electro-engineering product can be satisfied with and make conductor material, and some be had to the occasion of special shape requirement to conductor material The most inapplicable.Although utilizing the modes such as welding can also obtain abnormity copper bar, but bronze medal Site Welding difficulty being big, technological level It is difficult to grasp and control；Welding meeting lack of standardization causes the junction resistance such as solder side big, and heat is fast, copper bar can be caused because of overheated and Reduce the magnitude of current, even burn out copper bar.

Prior art CN204332408U discloses a kind of tin plating abnormity copper bar, including copper bar body, it is characterized in that copper bar The cross section of body is I-shaped, and the surface of described copper bar body is coated with layer of metal stannum.This tin plating abnormity copper bar can meet some The demand of the conductor material of special shape, but the electric current that bears of I-shaped middle part copper coin and physical stress are the biggest, in using It is easily deformed, causes the problem such as spark, electric discharge.

Summary of the invention

The purpose of this utility model is to provide that corrosion resistance is strong, the conducting copper of dependable performance.

For achieving the above object, the technical solution adopted in the utility model is: a kind of conducting copper, including copper bar originally Body, described copper bar body is that a horizontal edge and two vertical edges are constituted, described two vertical edges be positioned at the homonymy of horizontal edge and the top of two vertical edges with Horizontal edge connects, and described horizontal edge is provided with several the first through holes；The bottom of described two vertical edges the most outwards arranges a flanging, described The inner side of flanging arranges groove, and the outside of described flanging arranges copper hanger, and described copper hanger arranges the second through hole；Described copper bar Surface is through tin plating process.

It is preferred that the cross sectional shape of described groove is semicircle.

It is preferred that the length of described copper bar body is 45-50mm, width is 20-25mm, and thickness is 2-2.5mm.

Advantageous Effects of the present utility model is: the conducting copper of a kind of π shape structure that this utility model provides, can be complete Entirely substituting existing I-shaped copper bar, and whole copper bar meets with stresses and is uniformly dispersed, electric current, heating are also uniformly dispersed, and use Respond well.It is suitable for the various occasion multiple uses such as transformator, transformer station, power station to use, uses flexibly.And can be significantly Reduce Site Welding quantity, convenient installation, ensure using effect.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

Detailed description of the invention

A kind of conducting copper as shown in Figure 1, including copper bar body, described copper bar body is by horizontal edge 1 and two vertical edge structures Becoming, the top of homonymy and two vertical edges that described two vertical edges are positioned at horizontal edge 1 is connected with horizontal edge 1, described horizontal edge 1 be provided with several the One through hole 2.This conducting copper shape is π shape structure, the copper bar body of this π shape structure, can substitute existing I-shaped completely Shape copper bar, and whole copper bar meets with stresses and is uniformly dispersed, and electric current, heating are also uniformly dispersed, and using effect is good.Can be significantly Degree reduces Site Welding quantity, convenient installation, ensures using effect.The length of described copper bar body is preferably 45-50mm, width Being 20-25mm, thickness is 2-2.5mm.

The bottom of described two vertical edges the most outwards arranges a flanging 6, and the inner side of described flanging 6 arranges groove 5.Groove 5 Shape matches with components and parts to be connected, the cross sectional shape of described groove 5 preferably semicircle.

In order to conducting copper applicable surface of the present utility model is wider, easier for installation, preferably outside described flanging 6 Side arranges copper hanger 3, and described copper hanger 3 arranges the second through hole 4.Copper hanger 3 and the design of the second through hole 4, be convenient for changing with The components and parts that conducting copper is connected, and recycle conducting copper.

Metallic copper has good electric conductivity, but price is costly and the most oxidized.In order to further enhance this practicality The corrosion resistance of novel middle conducting copper, on the surface of copper bar body through tin plating process.Certainly, in order to be prevented effectively from because of by mistake Touch conducting copper and cause the danger such as electric shock, it is also possible at the surface configuration vinyon plate of described copper bar body, play and more enter The protective action of one step.
