Outer loop water pump is mutually connected and be connected to by rubber hose, forms whole circulation waterway, the semi arch of the lower fixture
The middle part of connected in star is equipped with forming tank, and the depth of the forming tank is greater than 3~5mm of depth of semicircular arc groove, width 30
~40mm.The aluminium conductor of two sections of cables to be welded is fixed on the two of lower fixture by left and right two parts of the upper fixture respectively
End, and it is located at the middle part of lower fixture at docking, welding material is heat-fused in formation solder joint at forming tank by soldering appliance.
The bottom of the upper fixture is equipped with screw rod, and the lower fixture is equipped with the through-hole cooperated with the screw rod, described
Left and right both ends of the left and right two parts respectively with lower fixture of upper fixture be fixedly connected by screw rod and fastening nut.
The beneficial effects of the utility model are: the utility model is had well using cooling water channel design is come into contact in a large area
Cooling effect, effective protection cable insulation will not be damaged in the welding process due to high temperature, meanwhile, fixture is in welding
Fixed cable ends to be welded can be stablized, and guarantee that Forming Quality is stablized at solder joint, make to weld more convenient operation, be led after welding
Body is not bent, and weld conductor is full after welding, there is preferable resistive performance.
