Busbar implementation structure

Abstract

This provides a mounting structure for a busbar that connects a circuit board to an external interface terminal. [Solution] The pair of nut members 3 comprises an inner nut member 31 located in a space S surrounded by a first plate member 11, a second plate member 12, and a third plate member 13, and an outer nut member 32 located on the opposite side of space S. An external interface terminal Y is connected to the open end of the screw member 2 that protrudes from the screwed outer nut member 32. The inner nut member 31 has a substantially square shape when viewed from the extending direction of the screw member 2 and has a size that prevents rotation due to being restricted by the first plate member 11 and the second plate member 12.

Claims

1. A busbar is electrically connected to a pattern formed on a substrate and has through holes formed in it, A screw member having screw threads cut into it and inserted into the through hole, A pair of nut members are screwed onto a threaded member inserted through the aforementioned through hole, from both sides of the busbar, Equipped with, The busbar comprises a first plate member positioned upright on the substrate, a second plate member positioned upright on the substrate so as to be substantially parallel to and opposite to the first plate member, and a third plate member positioned upright on the substrate so as to be substantially perpendicular to the first and second plate members, connecting the first and second plate members. The side of the first plate member on the substrate side and the side of the second plate member on the substrate side are in a plane position. The through hole is formed in the third plate member, The pair of nut members comprises an inner nut member located in the space enclosed by the first plate member, the second plate member, and the third plate member, and an outer nut member located on the opposite side of the space. An external interface terminal is connected to the open end of the screw member that protrudes from the screwed outer nut member. The busbar mounting structure is characterized in that the inner nut member has a substantially square shape when viewed from the extending direction of the screw member and has a size that is restricted by the first plate member and the second plate member so that it cannot rotate.

2. The busbar mounting structure according to claim 1, characterized in that the screw member is also inserted through a through hole formed in the housing, and the housing is sandwiched between the outer nut member and the third plate member.

3. The busbar mounting structure according to claim 1, characterized in that a first lead portion and a second lead portion extend from one side of the first plate member and one side of the second plate member, respectively, and are inserted into through holes formed on the substrate side.

4. A busbar is electrically connected to a pattern formed on a substrate and has through holes formed in it, A screw member having a screw head, having screw grooves cut into it, and being inserted into the through hole, An outer nut member is screwed onto a screw member inserted through the aforementioned through hole, Equipped with, The busbar comprises a first plate member positioned upright on the substrate, a second plate member positioned upright on the substrate so as to be substantially parallel to and opposite to the first plate member, and a third plate member positioned upright on the substrate so as to be substantially perpendicular to the first and second plate members, connecting the first and second plate members. The side of the first plate member on the substrate side and the side of the second plate member on the substrate side are in a plane position. The through hole is formed in the third plate member, The screw head is located in the space enclosed by the first plate member, the second plate member, and the third plate member. An external interface terminal is connected to the open end of the screw member that protrudes from the screwed outer nut member. The busbar mounting structure is characterized in that the screw head has a substantially square shape when viewed from the extending direction of the screw member and has a size that prevents rotation due to being restricted by the first plate member and the second plate member.
