Mother is fixed on the outer wall of babinet, and the wire through-hole for being passed through for aluminum conductor, the wire through-hole are offered on the nut
For counterbore, the wire through-hole is located on the center line of nut and is connected to the inside of babinet, between the aluminum conductor and nut
By being welded to connect.
Further, the nut is brass nut.
Further, the nut is hex nut.
Further, the outside of the nut is socketed with insulation sleeve, and the material of the insulation sleeve is rubber.
Further, spot welding glue is coated between the aluminum conductor and nut.
Compared with prior art, the beneficial effects of the utility model are：
Transformer in the utility model includes babinet, nut and aluminum conductor, nut be provided with it is multiple, nut is fixed
It is installed on the outer wall of babinet, wire through-hole is offered on each nut, aluminum conductor is made to pass through the wire through-hole, and conducting wire is logical
Hole is located on the center line of nut, and the wire through-hole is connected to the inside of babinet, i.e., aluminum conductor passes through the center of nut laggard
It realizes and connects with coil in cartonning body, specifically, realize connection between aluminum conductor and nut by welding so that aluminium is led
It can achieve a fixed connection between line and nut, more specifically, the aluminum conductor is flat type aluminium wire, be easier, will lead when in order to weld
Line three-way hole is set as oblate shape, so that the shape of wire through-hole is more matched with aluminum conductor, wire through-hole is counterbore so that solder is not allowed
It is easy to run off, solder can be coated along the perimeter of aluminum conductor, and then can improve the reliability of welding, ensure the quality of welding, be improved
Welding efficiency, keeps weld seam not easy to crack at the phenomenon that capable of avoiding the occurrence of rosin joint, avoids the use for influencing product, helps to improve
The quality of product.
