Abstract
The utility model discloses a low-resistance connection wire. The low-resistance connection wire comprises a receptacle and an aluminum strand wire which are fixedly connected together. The receptacle is made of iron, stainless steel or red copper. The aluminum strand wire is made from steel-cored aluminum strand wire, steel aluminum strand wire or pure aluminum strand wire. The receptacle and the aluminum strand wire are connected in a friction-welding manner. A stainless steel transition jacket is tightly clamped around the part close to the receptacle of the aluminum strand wire, and a protective jacket is covered around other parts of the aluminum strand wire. The protective jacket and the stainless steel transition jacket are closely rested to each other or spaced with a clearance therebetween. A protective layer is sleeved on the aluminum strand wire and the receptacle. One side of the protective layer is arranged on the section of the receptacle close to the stainless steel transition jacket, and the other side is arranged on the section of the protective jacket close to the stainless steel transition jacket. The connection wire has low resistance, stable electrical conductivity and reliable connection and contact. The stainless steel transition jacket is bonded and fused to the receptacle by friction-welding, so that the tensile strength of the connecting wire is greatly increased. In additional, the connecting wire has high safety performance, high temperature, corrosion and flame resistance, good insulating property and electrical safety.
Description
Technical field
The utility model relates to the connecting line technical field, especially relates to a kind of Low ESR connecting line that can be used for substituting measured length iron, copper connecting line.
Background technology
All need to use a large amount of cables in the productive life at present, its electric wire not only will possess the performance of bearing long-time energising, and must have certain pull resistance, the fail safe of various electric wires also more and more is subjected to people's attention in addition, the security incident that quality problems caused of cable itself also happens occasionally, especially for connecting line.Because the welding performance of aluminium is poor, band sheath aluminium stranded conductor (comprising steel wire aluminium stranded conductor, steel reinforced aluminium conductor) and iron in the prior art, stainless steel, when the red copper jointing is connected, the mode that generally adopts pressure clamp to compress connects.There is following defective in actual use in this kind crimping mode: the one, and adopt the formed connecting line joint of this kind crimping mode that electrochemical corrosion easily takes place under field conditions (factors), and cause the damage of aluminum steel; The 2nd, the joint of the made connecting line of this crimping mode under the energising situation not only influences the conductive characteristic of aluminium stranded conductor itself because contact resistance is bigger, and the joint heat that generates heat is bigger simultaneously, more aggravates the electrochemical corrosion of joint.To sum up, above-mentioned conventional pressure clamp compresses the made connecting line of mode, and not only electric conductivity is relatively poor relatively, and fragile in actual use, and security incident takes place often.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of Low ESR connecting line at above-mentioned deficiency of the prior art, and its impedance is low and conduct electricity very well, and can effectively solve conduction that the aluminium stranded conductor cable connects, reliably connect and the power supply safety problem.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of Low ESR connecting line, comprise the joint 1 and the aluminium stranded conductor that are fixed together, joint 1 is iron, stainless steel or red copper joint, described aluminium stranded conductor is the stranded aluminium stranded conductor of steel reinforced aluminium conductor, steel wire aluminium stranded conductor or pure aluminum wire 3,1 of described aluminium stranded conductor and joint are connected in the friction welding (FW) mode, aluminium stranded conductor is near the joint 1 part stainless steel spacer shell 5 that linked closely, the aluminium stranded conductor other parts are set with sheath 6, and described sheath 6 and stainless steel spacer shell 5 rely closely or there is the gap in the two; Be set with the overcoat that is used to seal on aluminium stranded conductor and the joint 1, overcoat one side is arranged on joint 1 near on a section of stainless steel spacer shell 5, and opposite side is arranged on sheath 6 near on a section of stainless steel spacer shells 5.
As a kind of preferred version of the present utility model, described stainless steel spacer shell 5 diameter of bores are greater than the aluminium stranded conductor diameter, and the wall thickness d of stainless steel spacer shell 5 is that 1-4mm, length L are 20-60mm.
As another kind of preferred version of the present utility model, described stainless steel spacer shell 5 is provided with and compresses place 7.
As another preferred version of the present utility model, described overcoat is an interlinkage polyethylene overcoat 4.
To sum up, adopt a kind of Low ESR connecting line of the utility model, have the following advantages: 1, Low ESR, electric conductivity is stable and it is reliable to connect, connecting line connects the junction different metal and fuses into one, contact is reliable and resistance is little; 2, tensile strength is big, and set stainless steel excessively cover also combines and fuses into one with iron, stainless steel, red copper joint by friction welding, has improved the tensile strength of connecting line greatly; 3, security performance height, it uses insulation, the waterproofing protection of interlinkage polyethylene as the junction, and high temperature resistant, corrosion-resistant, fire-retardant and good insulation preformance guarantees power supply safety admirably.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
