Abstract

The utility model relates to a conductive material, particularly a carbon fibre wire which is used in the electronic and electric fields and is used for heating. The carbon fibre wire comprises a carbon fibre filament, an insulating layer (1) which is coated on the carbon fibre filament, a metal filament and an insulating layer (2) which is arranged out of the metal filament. The corresponding ends of the carbon fibre filament and the metal filament are connected by a copper tube, and the copper tube is coated by an insulating external protecting layer. Both ends of the insulating external protecting layer are respectively connected with the insulating layers (1), (2) hermetically. Because the carbon fibre filament is placed in a continuous closed metal pipe, the possibility that the carbon fibre filament is worn by the end of the metal filament is avoided. The durability and the safety of products are improved. At the same time, because the copper tube is tightly pressed on the carbon fibre filament, the contact area between the carbon fibre and the copper tube is as large as possible. Therefore, the contact resistance between the carbon fibre and the copper pipe is efficiently reduced, and the contact resistance between the carbon fiber and a metal wire is efficiently reduced. Therefore, the practicable extent of products is improved.

Description

Carbon fiber line with splicing ear

Technical field

The utility model relates to electric conducting material, the carbon fiber line that is used to generate heat that use in particularly electric field.

Background technology

Carbon fiber line is widely used in having in the electronic and electrical equipment of heating function, generally at carbon fiber wire outer wrapping insulating barrier, but because carbon fiber wire weldbonding tin not, can't directly carbon fiber wire and metal solder be formed one with common welding method, and carbon fiber wire is made up of many filaments, every carbon filament is highly brittle, easily fractureed, rubbed easily when contacting with the metal end face, so when crimp commonly used carries out the crimping connection, rub easily, can't satisfy instructions for use, defectives such as and general connector connecting method exists contact resistance bigger, and long-term dependability is lower.

Technical scheme

The purpose of this utility model is to design a kind of above-mentioned defective that overcomes, and can satisfy instructions for use, has the carbon fiber line of better reliability.

The utility model comprises carbon fiber wire and is wrapped in its outer insulating barrier (); the utility model also comprises wire, is arranged on the outer insulating barrier (two) of wire; carbon fiber wire is connected with copper pipe with the wire opposite end; with insulation external protection parcel, the two ends of this insulation external protection are tightly connected with insulating barrier (), (two) respectively outside copper pipe.

Because carbon fiber wire is in the metal tube of continuous sealing, avoided the wire end face to rub the possibility of carbon fiber wire, durability of products and fail safe have been improved, simultaneously, because copper pipe is pressed on silk on the carbon fiber, big as far as possible contact area is just arranged between carbon fiber wire and the copper pipe, thus reduced effectively between carbon fiber and the copper pipe and with the contact resistance of metal cords, thereby improved the degree of being practical of product.

In addition, the end face by copper pipe is pressed on the insulating barrier of carbon fiber line, thereby has improved the tensile strength of product, and, when this copper pipe end face contacts with insulating barrier,, so also improved the permanence and the fail safe of product because the resistance to rubbing of insulating barrier is better than carbon fiber.

And; owing to adopted airtight external protection, make inner copper pipe isolated with extraneous air, so just reduced the possibility of copper generation oxidation; thereby do not adopt the scheme of airtight external protection to compare with other, reliability of products is further guaranteed.

In a word, the utility model production and processing is easy, and contact is reliable, and safe and effective, contact resistance is little, has solved during carbon fiber line is used the difficult point problem about joint, for the extensive use of carbon fiber line provides may.

Description of drawings

Accompanying drawing is the utility model structural representation

Among the figure, 1 carbon fiber wire, 2 insulating barriers (), 3 copper pipes, 4 insulating barriers (two), 5 wires, 6 external protections.

Specific embodiment

Carbon fiber wire 1 outer insulating barrier () 2 is delineated opening along its section direction, peel off the partial insulative layer () 2 of outside, the carbon fiber wire 1 that exposes the inside is in kind peeled off wire 5 outer partial insulative layers (two) 4 again, exposes the wire 5 of the inside.

With the carbon fiber wire 1 and wire 5 relative being wrapped in the copper pipe 3 that exposes; and compress, at copper pipe 3 overcoat external protections 6, its length is greater than copper pipe 3 length again; two ends form and are tightly connected with insulating barrier () 2, insulating barrier (two) 4 outer surfaces respectively, make product external surfaces form continuous insulating barrier.The double wall heat Heat-Shrinkable Tubings of band hot melt adhesive in external protection 6 can adopt.
