Abstract

A structure of connection among a circuit body, a bus bar and an electronic element includes a circuit body configured by a flexible board on which a wiring pattern is provided, a bus bar attached to a mounting surface of the circuit body, and an electronic element attached to the mounting surface so as to connect the bus bar and the wiring pattern. The bus bar has a fixed portion extending along the mounting surface. The fixed portion is fixed to the mounting surface so that a restricted area which restricts deformation of the mounting surface is formed in a periphery of the fixed portion. The electronic element is arranged in the restricted area and is fixed to the mounting surface.

First claim

What is claimed is:

1. A structure of connection among a circuit body, a bus bar and an electronic element, the connection structure comprising:
a circuit body configured by a flexible board on which a wiring pattern is provided;
a bus bar attached to a mounting surface of the circuit body; and
an electronic element attached to the mounting surface so as to connect the bus bar and the wiring pattern,
wherein the bus bar has a fixed portion projecting from a bus bar body and extending along the mounting surface;
wherein the fixed portion is fixed to the mounting surface so that a restricted area which restricts deformation of the mounting surface is formed in a periphery of the fixed portion;
wherein the electronic element is arranged in the restricted area and is fixed to the mounting surface;
wherein the fixed portion of the bus bar has a first portion extending in a direction along the mounting surface and a pair of second portions protruding from the first portion and extending in a direction intersecting with the first portion and along the mounting surface; and
wherein the first portion and the pair of second portions are fixed to the mounting surface so that the restricted area is formed in a part sandwiched between the pair of second portions.

2. The connection structure according to claim 1 ,
wherein the electronic element is attached to the mounting surface so as to connect the fixed portion and the wiring pattern.

3. The connection structure according to claim 1 ,
wherein the fixed portion is higher than the electronic element in a thickness direction of the circuit body; and
the connection structure further comprising:
a sealing member that is arranged in the restricted area formed by the fixed portion and covers the electronic element so as to isolate the electronic element from an outside.

4. The connection structure according to claim 1 ,
wherein the first portion and the pair of second portion form an L shape around the restricted area.

5. The connection structure according to claim 1 ,
wherein the fixed portion of the bus bar has a third portion extending in the direction intersecting with the pair of second portions; and
wherein the pair of second portions is disposed between the first portion and the third portion to form a rectangular shape around the restricted area.
