Abstract
The utility model relates to a silvered dumbbell-shaped copper bar. The copper bar comprises a copper bar body which is divided into an upper part and a lower part. The upper part is an upper layer copper bar body (2), and the lower part is a lower layer copper bar body (1). Both the upper layer copper bar body (2) and the lower layer copper bar body (1) have a rectangular cross section. The length of the long side of the upper layer copper bar body (2) is larger than that of the long side of the lower layer copper bar body (1). A dumbbell-shaped projection (3) is arranged on each of the left and right sides on the top of the upper layer copper bar body (2), and the copper bar body and the dumbbell-shaped projections (3) are all coated with silver. According to the utility model, the silvered dumbbell-shaped copper bar has a special shape with dumbbell-shaped projections, and is suitable for applications with special requirements on the shape of the cross section of the semiconductor, being able to be used instead of the conventional cooper bar; and the silver player increases the conductivity.
Description
Technical field
The utility model relates to a kind of silver-plated dumbbell shaped copper bar.
Background technology
Copper bar is to make middle-low voltage switch cabinet, bus-bar system, circuit breaker, transformer, railway, wind-force, nuclear power and the installation conductor materials such as hydroelectric generator and Highspeed Catenary.Traditional electrician is rectangular with the copper bar cross section, and rectangular copper bar can only be satisfied with general electric equipment products and make conductor material, for some, to conductor material, there is the occasion of special cross-section shape need can not be suitable for, thereby can not meet the demand of the electrical apparatus industry updating and upgrading of a product, and on electric conductivity also shortcoming to some extent.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the silver-plated dumbbell shaped copper bar that provides a kind of double cross-sectional area of conductor shape specific (special) requirements to be arranged and conduct electricity very well.
The purpose of this utility model is achieved in that
A kind of silver-plated dumbbell shaped copper bar, comprise the copper bar body, and described copper bar body is divided into upper and lower two parts, top is divided into upper strata copper bar body, bottom is divided into lower floor's copper bar body, and both cross sections all are rectangle, and wherein the long limit of upper strata copper bar body is greater than the length of lower floor's copper bar body; Copper bar body top in described upper strata each side is provided with a dumbbell shaped projection, at the outer surface of copper bar body and dumbbell shaped projection, is equipped with silver coating.
Compared with prior art, the beneficial effects of the utility model are:
The silver-plated dumbbell shaped copper bar of the utility model dumbbell shaped projection shape is special, can meet the occasion that double cross-sectional area of conductor shape has specific demand, can substitute traditionally shaped copper bar, and silver coating also can increase conductivity.
The accompanying drawing explanation
The structural representation that Fig. 1 is the silver-plated dumbbell shaped copper bar of the utility model.
Wherein:
Lower floor's copper bar body 1
Upper strata copper bar body 2
Dumbbell shaped projection 3.
Embodiment
Referring to Fig. 1, the silver-plated dumbbell shaped copper bar of the utility model, comprise the copper bar body, described copper bar body is divided into upper and lower two parts, top is divided into upper strata copper bar body 2, bottom is divided into lower floor's copper bar body 1, and both cross sections all are rectangle, and wherein the long limit of upper strata copper bar body 2 is greater than the length of lower floor's copper bar body 1; Copper bar body 2 tops, described upper strata each side are provided with a dumbbell shaped projection 3, at the outer surface of copper bar body and dumbbell shaped projection 3, are equipped with silver coating.
Dumbbell shaped projection 3 shapes are special, can meet the occasion that double cross-sectional area of conductor shape has specific demand, can substitute traditionally shaped copper bar, and silver coating also can increase conductivity.
Claims (1)
1. a silver-plated dumbbell shaped copper bar, comprise the copper bar body, it is characterized in that: described copper bar body is divided into upper and lower two parts, top is divided into upper strata copper bar body (2), bottom is divided into lower floor's copper bar body (1), both cross sections all are rectangle, and wherein the long limit of upper strata copper bar body (2) is greater than the length of lower floor's copper bar body (1); Described upper strata copper bar body (2) top each side is provided with a dumbbell shaped projection (3), at the outer surface of copper bar body and dumbbell shaped projection (3), is equipped with silver coating.
