The utility model discloses a take copper bar of protective coating is applicable to fields such as high-low voltage apparatus, switch contact, switch board, bus duct, transformer, relates to electrician's alloy material technical field.

Background

Copper bars, also known as copper busbars or copper bus bars, are made of copper materials, long conductors with rectangular or chamfered (fillet) rectangular cross sections are called aluminum bars made of aluminum materials, and the aluminum bars have the functions of current transmission and electrical equipment connection in circuits. In devices such as distribution device, high and low voltage apparatus, transformer, inside is walked line and components and parts are more, and the wiring is denser, uses traditional copper bar product to take into account inside before the installation and walks the line rationality and occupy bigger space, prevents that inside is walked the line too densely and the potential safety hazard that causes when leading to two or more electrical equipment to connect, and inevitable messenger's whole electrical apparatus designs too big. Moreover, the traditional copper bar is exposed in the air, and verdigris is easily generated in the long-term use process, so that the conductivity of the electrical equipment is influenced, and the service life of the electrical equipment is prolonged. Therefore, in order to improve the problems of safety and product life of the traditional copper bar product, the applicant makes a beneficial design and finds a method for solving the problems, and the technical scheme to be described below is generated under the background.

Disclosure of Invention

The utility model discloses an aim at overcoming the weak point that above-mentioned traditional copper bar design exists, provide a product security height, long service life's product.

In order to solve the above problems, the utility model adopts the following technical proposal.

The utility model provides a take protective coating's copper bar, includes first copper, second copper and connecting plate, first copper sets up in the connecting plate one side, the second copper sets up in the connecting plate another side, first copper, second copper link to each other with the connecting plate and are the Z shape, first copper is equipped with first through-hole, the second copper is equipped with the second through-hole, the connecting plate one side is equipped with the locating hole, first copper, second copper and connecting plate surface are with protective coating.

Preferably, the width and the thickness of the first copper plate, the second copper plate and the connecting plate are consistent, and a height difference is arranged between the first copper plate and the second copper plate.

Preferably, the distance between the center point of the first through hole and the connecting plate is the same as the distance between the center point of the second through hole and the connecting plate, the diameter of the first through hole is the same as that of the second through hole, and the center points of the first through hole and the second through hole are located in the middle of the width of the first copper plate and the width of the second copper plate.

Preferably, a chamfer is arranged at the inlet of the positioning hole.

Preferably, the surfaces of the first copper plate, the second copper plate and the connecting plate are provided with electroplated nickel.

Preferably, the first copper plate, the second copper plate and the connecting plate are integrally processed.

Has the advantages that:

compared with the prior art, the beneficial effects of the utility model are that:

(1) The utility model discloses, the width of first copper, second copper, connecting plate is unanimous, and this design reduces the production of shearing the waste material, improves the mould utilization ratio, reduction in production cost to, because the width of copper bar is unanimous with thickness, the stability has been guaranteed to the heavy current that makes through the copper bar. Be equipped with certain difference in height between first copper bar and the second copper bar, when guaranteeing copper bar structural strength, avoid two electrical equipment because the potential safety hazard that electric arc caused is aroused to the excessive nearness, improve the inside line space of walking of electrical device after the installation, increase its security.

(2) The utility model discloses, the surface of copper and connecting plate scribbles the electronickelling, mainly plays the guard action, prevents that the surface from producing verdigris, oxidation, vulcanization etc to possess pleasing to the eye, corrosion-resistant use, because the hardness of copper is less, warp easily in the installation, consequently, can improve hardness at copper bar surface nickel plating, prevent that the copper bar from warping.

Detailed Description

In the prior art, as shown in fig. 1-5, the copper bar with the protective coating of the present invention is further described below, by the design that the height difference between the first copper plate and the second copper plate and the surface of the copper bar are coated with the protective layer, so as to achieve the purpose of high safety and long service life.

First copper 1, second copper 2, connecting plate 3 are integrated into one piece and form, and the copper bar width and the thickness of tailorring are unanimous for the electrical equipment output current of connecting the copper bar can be even carry the electrical equipment that second copper 2 links to each other through first copper 1 on, increase its stability that bears the circulation current. The height difference is arranged between the first copper plate 1 and the second copper plate 2, so that certain creepage distance and electric clearance are formed between two connected electric devices, and the electric arc generated by the output end of one main loop and the input end of another electric device or a plurality of electric devices due to too close distance is prevented from causing misoperation of the electric devices.

First copper 1,

second copper

2 and 3 surfaces of connecting plate scribble the electronickelling, can guarantee to warp by a wide margin in the installation, reduce in the transportation and warp, simultaneously, guaranteed in the long-term use, because of the bad influence such as the copper green that the oxidation produced, vulcanization, cause the electrical equipment conductivity to reduce and then shorten product life, this design protects the bad influence that the copper bar produced copper green when considering beautify the product to the life of extension electrical equipment.

By adopting the method, the stability of bearing circulating current is improved, the electric clearance, the creepage distance and the internal wiring space are improved, the safety of the electrical equipment is ensured, and the surface is coated with the protective layer, so that the service life of the product can be prolonged, the service life of the electrical equipment can be prolonged, and the like.

The above description is for further details of the present invention, and it is not assumed that the embodiments of the present invention are limited to these descriptions, and it is obvious to those skilled in the art that the present invention can be implemented by a plurality of simple deductions or replacements without departing from the concept of the present invention, and all should be considered as belonging to the protection scope defined by the claims submitted by the present invention.
