Description
Technical field
The utility model relates to a kind of tin-coated copper bar, belongs to electrical facility technical field.
Background technology
Copper bar is a kind of conducting heavy current product, play conveying electric current in circuit and be connected electric equipment, be applicable to the electro-engineerings such as high and low voltage electrical equipment, switch contact, controller switching equipment, bus duct, be also widely used in the super-large current electrolysis for production engineering such as metal smelt, electrification plating, chemical industry caustic soda.Traditional electrician has the following disadvantages with copper bar: the cross section of copper bar is rectangular, rectangular copper bar can only be satisfied with general electric equipment products and make conductor material, there is the occasion of special cross-section shape need then can not be suitable for for some to conductor material, as: for the element original paper rectifier dispelling the heat, conduct electricity, thus can not meet the demand of the electrical apparatus industry updating and upgrading of a product; Secondly the copper bar of square-section, its conductive area is little, and is made up of fine copper, therefore poor electric conductivity; The copper bar of square-section, its installing space is limited; In addition, the copper bar as big current carrier adopts rectangular configuration to be also unfavorable for radiating and cooling.
Utility model content
The deficiency that the utility model exists for prior art, provides a kind of structure simple, and can meet the tin-coated copper bar of some special shape needs.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of tin-coated copper bar, comprise copper bar body, it is characterized in that, the outer surface of described copper bar body is tin coating, described copper bar body comprises plane, bottom surface and a left side, right flank, described left surface is provided with the first outer lug edge from top to bottom, second outer lug edge, described right flank is provided with the 3rd outer lug edge from top to bottom, lug edge all round, the first groove is provided with between described first outer lug edge and the second outer lug edge, described 3rd outer lug edge and is provided with the second groove all round between lug edge, the middle part of described bottom surface is provided with the 3rd groove, the cross section entirety of described copper bar body is in " scholar " type.
Further, described first groove, the second groove and the 3rd groove are rectangular channel, and described first, second, third, fourth outer lug edge is all rectangular configuration, and the width of described upper plane is greater than the width between described first groove and the second groove.
Further, described first outer lug edge is concordant with the upper surface of the 3rd outer lug edge, and described second outer lug edge and all round lug edge is symmetrical arranged.
Further, the height of described second groove is greater than the height of described first groove.
The beneficial effects of the utility model are, the cross section entirety of the utility model copper bar is in " scholar " type structure, occasion conductor material being had to special cross-section shape need can be applicable to, meet the demand of the upgrading of electrical apparatus industry, copper bar adopts the outer lug edge design bending strength of multiple rectangular configuration high, be out of shape minimum, and the applicable more requirements of installation space of groove between outer lug edge and on bottom surface, in addition the structure of outer lug edge also effectively increases conductive area, improves the electric conductivity of copper bar.
