Description

The combined type conducting body

Technical field

The utility model belongs to the electric conductor technical field, relates in particular to a kind of combined type conducting body.

Background technology

At present, China is in fields such as electric power, communication, lightning protections, and the electric conductor that uses is generally fine copper metallic article (as lightning-proof grounding body, copper bar, copper strap wire and line hardware etc.), conductive rubber based article or bimetallic article (as copper cover aluminum etc.).

It is large that the fine copper metallic article not only consumes noble metal copper amount, and expensive, and cost is high; Though conductive rubber based article cost is low, poor electric conductivity, non-refractory, useful life is short; And bimetallic article must adopt special-purpose production equipment, and not only qualification rate is low, the waste raw material, and also personnel have high input, and labour intensity is high, and production efficiency is low, and therefore existing electric conductor combination property is poor.

The utility model content

Technical problem to be solved in the utility model is: provide a kind of combined type conducting body, to solve the existing poor technical problem of electric conductor combination property.

For solving the problems of the technologies described above, the technical solution of the utility model is: the combined type conducting body, comprise graphite cake, and described graphite cake outer surface is coated with metal layer.

As a kind of improvement, described metal level and described graphite cake are combined as a whole.

As further improvement, described graphite cake is that carbon content is the high-carbon graphite plate more than 99%.

As further improvement, described metal level is the outer conducting layer that silver or copper or stainless steel are made.

After having adopted technique scheme, the beneficial effects of the utility model are: due to the combined type conducting body, comprise graphite cake, described graphite cake outer surface is coated with metal layer, and described graphite cake good conductivity, high temperature resistant, corrosion-resistant, thermal conductivity is good, thereby can adapt to various environment, not only long service life, and low cost of manufacture, alternative fine copper metallic article, conductive rubber based article and part bimetallic material etc., can save raw material metal 50%, good in economic efficiency.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

As shown in Figure 1, the combined type conducting body, comprise graphite cake 1, graphite cake 1 outer surface is coated with metal layer 2, metal level 2 is closely as one with graphite cake 1, graphite cake 1 is high-carbon graphite plate more than 99% for carbon content, and the outer conducting layer that metal level 2 is made for silver, copper, 304 stainless steels or 316 stainless steels etc. is given an example no longer one by one at this.

As shown in Fig. 2 and Fig. 3 were common, lightning-proof grounding body 3 comprised graphite cake 1, and graphite cake 1 outer surface is coated with copper layer 4, due to graphite cake 1 good conductivity, corrosion-resistant, thereby be difficult for being corroded, be embedded in underground can the use for a long time, its longer service life, manufacturing cost is lower.

As shown in Fig. 4 and Fig. 5 were common, copper bar 5 comprised graphite cake 1, and graphite cake 1 outer surface is coated with copper layer 4, and is anticorrosive because graphite cake 1 is high temperature resistant, and thermal conductivity is good, therefore longer service life when instead of pure metal copper bar, and manufacturing cost is lower.

The combined type conducting body that the utility model provides, owing to comprising graphite cake 1, graphite cake 1 outer surface is coated with metal layer 2, graphite cake 1 good conductivity, high temperature resistant, corrosion-resistant, thermal conductivity is good, thereby can adapt to various environment, not only long service life, and low cost of manufacture, alternative fine copper metallic article, conductive rubber based article and part bimetallic material etc. can be saved raw material metal 50%, and are good in economic efficiency.

The utility model can be used for the line hardwares such as power communication equipment and copper bar, copper strap wire, binding post, conducting rod, wire clamp, clamp; the earthing material such as lightning-proof grounding body and down conductor; also can be used for the protection of the high-tension electricity circuits such as distribution board, High-low voltage switch cabinet, electric cabinet and equipment thereof, and nuclear power, boats and ships and aerospace cable and connecting line.

The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
