Abstract
The utility model relates to a copper-aluminum connecting wire, which is suitable for an electric power supply and distribution wire. The internal part of the copper-aluminum connecting wire is provided with a copper-aluminum connecting tube; a copper directing line and an aluminum directing line are respectively pressed and connected in the copper-aluminum connecting tube; the external side of the copper-aluminum connecting tube is fixed with a heat-shrinkable tube, and simultaneously, the connection of the friction welding is arranged between the copper connecting tube and the aluminum tube in the copper-aluminum connecting tube. Accordingly, the utility model which is not easy to break the wire has the advantages of reasonable structural design, good tensile strength, small resistance, safe electricity supply, etc.
Description
The utility model relates to a kind of connecting line, particularly a kind of copper, aluminium connecting line, and it is applicable in the power supply and distribution of electric power circuit.
In present power supply and distribution of electric power circuit, what adopt being connected of copper conductor and aluminum conductor is canoe, after promptly twining by hand with two kinds of different plain conductors, wrap insulating tape or autoadhesion adhesive tape more outside, there is following shortcoming in actual use in this traditional wiring construction: 1, can not guarantee two kinds of fine contacts of different metal conductive line surfaces, especially 10 millimeters
2Above strand wire, thereby reduced conductive section, under the situation of rated current or slight overload, will cause conductor joint heating, conductor temperature raises, and causes the conductive line surfaces oxidation, and resistance increases, so vicious circle, the result causes joint to blow, thus interruption of power supply or cause fire incident; Need repeatedly bending during 2, owing to winding, low intensive aluminum steel has reduced tensile strength thus, very easily breaks in the joint; 3, insulating tape and autoadhesion adhesive tape are to be made by fiber and colloidal materials, when the joint heating temperature raises, and easily carbonization, can cause burning when meeting naked light or reaching uniform temperature, outdoor application is unable to undergo to expose to the sun and rain, very easily lose insulating effect, cause Danger Electric shock risk.According to statistics, south of a city power supply administration of Hangzhou power office 2715 of all kinds of accident of power supplys of coprocessing between the megathermal period on June 24th, 1 to August 20, wherein disconnection fault reaches 1869, account for 69.9% of total failare, as seen, traditional wiring construction is extremely unreasonable, and accident is too many.
The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, uses reliable and can guarantees the copper aluminium connecting line of safe power supply.
The purpose that the utility model proposed can be achieved through the following technical solutions: design has copper aluminium to take over, and copper conductor and aluminum conductor are crimped on respectively in the adapter of copper aluminium, and at copper aluminium adapter external fixation heat-shrinkable tube is arranged.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model.
Following the utility model will be described in further detail in conjunction with the accompanying drawings and by embodiment.
Referring to Fig. 1; this copper aluminium connecting line is by copper conductor 1; aluminum conductor 3; copper aluminium takes over I and heat-shrinkable tube 2 is formed; copper conductor 1 and aluminum conductor 3 are crimped on copper aluminium respectively and take in the I; make copper conductor 1 directly contact like this with the copper connecting tube 4 of copper aluminium adapter I; and the aluminium adapter 5 that makes aluminum conductor 3 and copper aluminium take over I directly contacts; thereby the lead of having avoided two kinds of varying strengths directly contacts and the repeatedly crooked consequence that is caused; simultaneously; the crimping structure that is adopted significantly improves the tensile strength of connecting line; copper connecting tube 4 is connected 5 and then adopts friction welding (FW) to connect with aluminium; for making this connecting line possess the effect of continuous protection; outside taking over I, copper aluminium is with heat-shrinkable tube 2; it is taken over I by heat baking and copper aluminium and fixes, and these heat-shrinkable tube 2 apparatus are made up of good flexibility and the combustible crosslinked polymers of high resistant.
During use, as long as this copper aluminium connecting line is installed in desired location, at copper conductor 1 termination copper cash, aluminum conductor 3 termination aluminum steels can be used safely.
The utility model compared with prior art has the following advantages: 1, the copper aluminum steel is in conjunction with tight, and tensile strength is good: copper, aluminum conductor and copper aluminium are taken over crimping, belong to metal of the same race and bear the not combination of pressure of the same race, so it is difficult for broken string; 2, copper aluminium is taken over and is adopted friction welding (FW) to connect, and the junction of different metal is fused into one, and contact-making surface is reliable, and resistance is little, and temperature rise is in allowed band, thereby it is reliable to guarantee to power; 3, use the heat-shrinkable tube that formed by crosslinked polymers as the junction insulation protection, high temperature resistant, corrosion-resistant, fire-retardant and good insulation preformance, thus guaranteed safe power supply.
Claims (2)
1, a kind of copper aluminium connecting line comprises copper conductor and aluminum conductor, it is characterized in that: also design has copper aluminium to take over (I), and copper conductor (1) and aluminum conductor (3) are crimped on copper aluminium respectively and take in (I), and at copper aluminium adapter (I) external fixation heat-shrinkable tube (2) is arranged.
2, copper aluminium connecting line as claimed in claim 1 is characterized in that: the copper connecting tube (4) in the described copper aluminium adapter (I) is taken between (5) with aluminium and is connected with friction welding (FW).
