The preferred a kind of aluminium tube joint for the aluminum pipe wire jumper again that the utility model provides, described connector is bolt, described bolt is that regular screw threads, Major Diam are 10mm.
Another preferred a kind of aluminium tube joint for the aluminum pipe wire jumper that the utility model provides, described coupling internal diameter is greater than in aluminum pipe external diameter 0.2～0.5mm, and described coupling inwall is that electric contact-making surface roughness is not more than 12.5 μ m.
Another preferred a kind of aluminium tube joint for the aluminum pipe wire jumper that the utility model provides, described bolt is symmetrically distributed and is arranged on the coupling both sides.
Another preferred a kind of aluminium tube joint for the aluminum pipe wire jumper that the utility model provides, described coupling surface is rounding off type profile, the position after described bolt is installed is lower than bolt hole.
Another preferred a kind of aluminium tube joint for the aluminum pipe wire jumper that the utility model provides begins to beat screw at each 95mm place, described nipple center line both sides.
The utility model provides another preferred a kind of aluminium tube joint for the aluminum pipe wire jumper is beaten screw in the axial upright position of described aluminum pipe, and described screw and nipple Kongxiang perpendicular to axial direction is corresponding.
Because the beneficial effect that has adopted technique scheme, the present invention to obtain is:
1, aluminium tube joint Stability Analysis of Structures in the utility model, machinery, electric property is good;
2, aluminium tube joint is simple in structure in the utility model, and cost is low and can be used as the Technological improvement plan that builds up the circuit aluminium tube joint;
3, in the utility model in aluminum pipe and the aluminum pipe nipple corresponding hole connect by slotted pan head screw or slotted cheese head screw, it is locked to form structure, and the situation of aluminum pipe slippage can not take place;
4, aluminum pipe coupling surface rounding off type profile in the utility model, the position after bolt is installed is lower than bolt hole, avoids the generation of corona;
The position was certain when 5, the boss of aluminum pipe nipple was guaranteed the aluminium tube joint integral installation in the utility model, can not be offset.
