Step 1:The restrictive coating for peeling off cable ends head, keeps the end of cable outer conductor exposed;

Step 2:One layer of scaling powder is coated in the cross cut end (of a beam) of cable outer conductor, makes cross cut end (of a beam)

Oxide layer eliminate;

Step 3:In copper sleeve and after having removed the end of surface oxide layer, copper sleeve is worn

Enter cable socket;

Step 4:It will be added without lead ring between copper sleeve and cable outer conductor using induction brazing machine

Solid tin wire bond is protected to connect.

Induction brazing is that the metal works for needing to weld are placed in induction coil, and induced electricity is generated by high-frequency alternating current Magnetic field couples in workpiece surface and generates induced electromotive force, forms inductive loop in metal surface, relies on metal surface generation Eddy-current heating can generally coat welding powder in welding position, until workpiece welds when reaching brazing filler metal melts temperature.

Preferably, the cable is 1/2 common cable or 1/2 super flexible cable.

Preferably, the cable outer conductor is aluminum pipe, the aluminum pipe helically tubulose or corrugated tube shape.

Preferably, the aluminum pipe helically tubulose when, wave crest be 12 ± 0.25mm, trough be 8.9 ± 0.25mm, pitch For 3.0 ± 0.2mm.When the aluminum pipe is in corrugated tube shape, wave crest is 113.9 ± 0.25mm, and trough is 12.2 ± 0.3mm, section Away from for 5.0 ± 0.3mm.

Preferably, the insulating layer is polyethylene foamed.It is a series of superior with heat preservation, moisture-proof, abrasion-proof, corrosion-resistant etc. Use characteristic.

Preferably, the scaling powder is that Al/Cu is brazed efficient scaling powder.There is pole to aluminium and copper dissimilar material low temperature brazing Good welding performance can quickly remove aluminium, aluminium alloy, copper and copper alloy surface oxide layer, make solder joint it is full, it is bright with it is secured, Two end faces coated in aluminum hull, can accelerate flowing of the solder in aluminum hull end face, keep the welding of aluminum hull and copper sleeve more firm.

Preferably, the current control of the induction brazing machine is within the scope of 36-38A, and induction brazing machine temperature is 220 DEG C- 380℃。

Preferably, the diameter range of the pure solid tin silk of the leadless environment-friendly is between 1.0-2.0.

Preferably, the sheath is PE materials or low smoke and zero halogen material.

The beneficial effects of the present invention are:The present invention, as cable outer conductor, alleviates the entirety weight of wire jumper using aluminum pipe Amount is brazed efficient scaling powder by aluminum pipe together with weld, due to Al/Cu using induction brazing machine technology using Al/Cu Be brazed efficient scaling powder has splendid welding performance to aluminium and copper dissimilar material low temperature brazing, quickly removes aluminum tube surfaces oxidation Layer improves the mobility of tin silk when welding, keeps solder joint more firm, aluminum pipe is made to be not easily disconnected from connector, effectively improve patch cord performance.

Specific implementation mode

The present invention is about a kind of aluminium wire jumper manufacturing method for communication base station, including wire jumper, the wire jumper include cable And copper sleeve, the copper sleeve are respectively provided at the both ends of cable, the cable includes inner wire, insulating layer, aluminum pipe from the inside to the outside And restrictive coating, the inner wire are made of copper clad aluminum flexible cord, and polyethylene foamed insulating layer is arranged on copper clad aluminum flexible cord, foaming Polyethylene layer has heat preservation, moisture-proof, abrasion-proof, corrosion-resistant etc. a series of superior using characteristic, is arranged outside insulating layer One layer of PE sheath or low smoke and zero halogen material is arranged in aluminum tube surfaces in aluminum pipe.Its step are as follows:

Step 1:The restrictive coating for peeling off cable ends head, keeps the end of cable outer conductor exposed;

Step 2:One layer of scaling powder is coated in the cross cut end (of a beam) of outer conductor, makes the oxygen of cross cut end (of a beam)

Change layer to eliminate;

Step 3:In copper sleeve and after having removed the end of surface oxide layer, copper sleeve is worn

Enter cable socket;

Step 4:It will be added without lead ring between copper sleeve and cable outer conductor using induction brazing machine

Solid tin wire bond is protected to connect.

Induction brazing is that aluminum pipe and copper sleeve are placed in induction coil, and induction field is generated by high-frequency alternating current, It is coupled on copper sleeve surface and generates induced electromotive force, formed inductive loop in aluminum tube surfaces, rely on the whirlpool of aluminum tube surfaces generation Stream fever, coats Al/Cu in welding position and is brazed efficient scaling powder, and aluminum pipe and copper sleeve are welded on one by solid tin silk It rises.
