Specific embodiment

It names preferred embodiment, and becomes apparent from intactly illustrating the utility model with reference to attached drawing.

Earthing or grounding means on rear side of the interchanger of the present embodiment, interchanger rear side earthing or grounding means are mounted on interchanger housing 1, such as Shown in Fig. 1 and Fig. 2, earthing or grounding means includes mounting portion 2 and conduct piece 3 on rear side of interchanger, and mounting portion 2 is located at interchanger housing 1 Outside, mounting portion 2 include body part 21, pit part 22 and mounting hole 23, and body part 21 is around pit part 22, and pit part 22 is relatively In the surface of body part 21 to the inner recess of interchanger housing 1, mounting hole 23 is located at the center of pit part 22.Conduct piece 3 with Pit part 22 is bonded and is electrically connected.

By setting a pit part 22 on interchanger housing 1, can be touched before baking vanish with baking vanish protection film Pit part 22, there are a steps, such setting between pit part 22 and body part 21 can improve conduct piece 3 and mounting portion 2 conductive contact performance.The reason is that, first, baking vanish protection film shares pit part 22 closely along step sticker, this makes it possible to Ensure the positional precision of baking vanish protection film, baking vanish region is made to keep certain boundary with conductive region, ensure conduct piece 3 and peace The contact area of conductive region in dress portion 2.Secondly, during 1 baking vanish of interchanger housing, the particle of baking vanish is not easy to cross Step is diffused into pit part 22, and after baking vanish, the surface of pit part 22 does not have baking vanish particle, ensure that conduct piece 3 and installation The contact quality of conductive region in portion 2.

As shown in Fig. 2, conduct piece 3 includes contact ring 31 and conducting wire 32, conducting wire 32 is connected to the side of contact ring 31, contact The end face of ring 31 is bonded with pit part 22, and conducting wire 32 is grounded.Contact ring 31 is convenient for that conduct piece 3 is allowed to be fixed on mounting portion 2, And contact the pit part 22 that ring 31 can make conduct piece 3 be preferably bonded mounting portion 2.
