Abstract
The utility model relates to a tinned multihole copper bar and belongs to the technical field of electrical alloy materials. The tinned multihole copper bar comprises a copper bar body (1), wherein the cross section of the copper bar body (1) is abnormally formed and consists of a left, a middle and a right part, the left part is a right trapezoid segment (11), the right part is a rectangular segment (13), and the middle part is a transitional oblique segment (12); and the middle of the right trapezoid segment (11) is provided with a first cylindrical through hole (111) along the length direction of the copper bar, the middle of the rectangular segment (13) is provided with an oblong through hole (131) and a second cylindrical through hole (132) from left to right along the length direction of the copper bar, and the middle of the right side of the rectangular segment (13) is provided with a groove (133) along the length direction of the copper bar. In the utility model, the cross section of the copper bar body is abnormally formed, therefore the tinned multihole copper bar can be applicable to occasions having special requirements on cross section shapes of conducting materials, thus meeting the demand of upgrading and updating products of the electrical appliance industry; and furthermore, the external surface of the copper bar is coated with a layer of metallic tin so as to improve the electric conductivity of the copper bar.
Description
(1) 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, distribution board, circuit breaker, transformer, railway, wind-force, nuclear power and high-speed electric railway contact line etc.Belong to electrical alloy material technology field.
(2) background technology
The electrician is to make installation conductor materials such as mesolow switch cubicle, bus-bar system, distribution board, circuit breaker, transformer, railway, wind-force, nuclear power and high-speed electric railway contact line with copper bar.Traditional electrician has the following disadvantages 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 do not satisfy the demand of the electrical apparatus industry updating and upgrading of a product.
2, copper bar is made by fine copper, its electric conductivity a little less than.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can be applicable to the zinc-plated porous copper bar that conductor material is had the occasion of special cross-section shape need and conducts electricity very well.
The purpose of this utility model is achieved in that a kind of zinc-plated porous copper bar, comprise the copper bar body, described copper bar body cross-section is abnormally-structured, form by left, center, right three parts, wherein left-hand component is the right-angled trapezium section, right-hand component is a rectangular section, mid portion is oblique section of transition, centre in described right-angled trapezium section is provided with one first cylindrical hole along described copper bar length direction, in the middle of described rectangular section, be provided with a square through hole and one second cylindrical hole from left to right along described copper bar length direction, in the middle of the right side of described rectangular section, be provided with a groove, and be coated with layer of metal tin at the outer surface of described copper bar body along described copper bar length direction.
The beneficial effects of the utility model are:
1, the employing of the cross section of the utility model copper bar is abnormally-structured, 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 the outer surface at copper bar is coated with layer of metal tin, can increase the electric conductivity of copper bar.
(4) description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of the zinc-plated porous copper bar of the utility model.
Reference numeral among the figure:
(5) embodiment
Referring to Fig. 1, Fig. 1 is the cross-sectional structure schematic diagram of the zinc-plated porous copper bar of the utility model.As seen from Figure 1, the zinc-plated porous copper bar of the utility model, comprise copper bar body 1, described copper bar body 1 cross section is abnormally-structured, form by left, center, right three parts, wherein left-hand component is right-angled trapezium section 11, right-hand component is a rectangular section 13, mid portion is a tiltedly section 12 of transition, centre in described right-angled trapezium section 11 is provided with one first cylindrical hole 111 along described copper bar length direction, in the middle of described rectangular section 13, be provided with a square through hole 131 and one second cylindrical hole 132 from left to right along described copper bar length direction, in the middle of the right side of described rectangular section 13, be provided with a groove 133, and be coated with layer of metal tin 2 at the outer surface of described copper bar along described copper bar length direction.
Claims (1)
1. zinc-plated porous copper bar, comprise copper bar body (1), it is characterized in that described copper bar body (1) is made up of left, center, right three parts, wherein left-hand component is right-angled trapezium section (11), right-hand component is rectangular section (13), mid portion is a tiltedly section (12) of transition, centre in described right-angled trapezium section (11) is provided with one first cylindrical hole (111) along described copper bar length direction, in the middle of described rectangular section (13), be provided with a square through hole (131) and one second cylindrical hole (132) from left to right along described copper bar length direction, in the middle of the right side of described rectangular section (13), be provided with a groove (133), and be coated with layer of metal tin (2) at the outer surface of described copper bar body (1) along described copper bar length direction.
