FIXATION STRUCTURE
FIG6 is a cross-sectional view illustrating the exemplary configuration of the fixation structure according to the second embodiment
The opening 41c of the housing 40 is blocked by the lid unit 42 while the board 20 housed in the housing space 41d is fixed to the second bottom surface 41i by a screw 23 (refer to FIG6). Then, the screws 32b are screwed into cylindrical parts 32a of the fixation parts 32 through the through-holes 41f of the second bottom surface 41i so that the stapler 30A is fixed to the board 20 in the housing 40. In this case, the contact part 31a of the stapler 30A integrated with the lid unit 42 contacts the core-wire exposed part 11 and the core-wire covered part 12 of the electrical wire 10 connected with the board 20. Heads of the screws 32b are positioned at the stepped part 41g between the first bottom surface 41h and the second bottom surface 41i, and do not protrude from the first bottom surface 41h as the lowermost surface of the housing 40. In the fixation structure 1A, since the stapler 30A is fixed to the board 20 by the screws 32b, constant fixation force can be achieved. In addition, in the fixation structure 1A, resin used for the stapler 30A are not limited unlike a case in which end parts of the resin fixation parts 32 are melted to achieve fixation.

['1. A fixation structure (1, 1A, 1B) comprising: an electrical wire (10) including a core wire (10a) that is conductive and a cover member (10b) that covers the core wire (10a), the electrical wire (10) including a core-wire covered part (12) covered by the cover member (10b) and a core-wire exposed part (11) exposed from the core-wire covered part (12); a board (20) including a junction part (22) electrically connected with the core-wire exposed part (11); and a stapler (30, 30A) including a contact part (31a) that has a plate shape and is positioned at a boundary (13) between the core-wire exposed part (11) and the core-wire covered part (12) while contacting the core-wire exposed part (11) and the core-wire covered part (12) from a side opposite to the board (20) when the core-wire exposed part (11) is connected with the junction part (22), and a pair of fixation parts (32) that are provided on both sides of the contact part (31a) and fix the contact part (31a) and the board (20).', '5. The fixation structure (1A, 1B) according to any one of claims 1 to 4, further comprising: a housing (40, 40B) to which the board (20) is assembled, wherein the housing (40, 40B) includes a housing unit (41, 41B) that has a box shape with an opening (41c) and that houses the board (20), and a lid unit (42) that is integrated with the stapler (30, 30A) and blocks the opening (41c), and the contact part (31a) of the stapler (30, 30A) integrated with the lid unit (42) contacts the core-wire exposed part (11) and the core-wire covered part (12) of the electrical wire (10) connected with the board (20) when the board (20) is housed in the housing unit (41, 41B) and the opening (41c) is blocked by the lid unit (42).']
