The current guiding part 304 is located in the current/voltage connection terminal 4 and is directly connected to the current/voltage connection terminal 4 . Compared with the original mutual protruding screw connection, this method not only greatly reduces production costs (materials), but also improves production efficiency and product qualification rate.

The inside of the current/voltage connection terminal 4 is made of iron. The iron material is more conducive to conduction between the transformer connection contact 3 and the current/voltage connection terminal 4 .

The current/voltage connection terminal 4 is square; the flow guide part 304 is oblate and square, and the large side of the flow guide part 304 is in direct contact with the inner wall of the current/voltage connection terminal 4 . The contact area between the current/voltage connection terminal 4 and the transformer connecting contact 3 is large, so that a larger current can pass through, and the application range is wider.
