Since it arrange | positions so that engagement to the edge part of the insertion port 13 is possible, it can prevent that the fixing | fixed part 15 slips out of the insertion port 13, and can hold | maintain the state in which the fixing | fixed part 15 was inserted in the insertion port 13. .

(Fourth embodiment)
A fourth embodiment will be described with reference to FIGS.

  In the bus bar and terminal fixing structure 301 according to the present embodiment, the fixing portion 303 is formed in a hook shape.

  In addition, the same code | symbol is attached | subjected to the structure similar to other embodiment, and description of a structure and function shall refer to other embodiment, and since it is the same structure, the effect | action and effect obtained are the same. It is the same.

  As shown in FIGS. 9-12, the fixing | fixed part 303 is formed in the hook shape by which the front end side was turned back toward the terminal through-hole 7 side, and was curved toward the direction away from the terminal 9 from a base end to a front end. Yes.

  Here, the insertion port 13 of the curved portion 11 is provided with a through hole that is twice as large as the insertion port 13 with respect to the bus bar 5, and then the curved portion 11 is formed with a straight line passing through the center of the through hole as a bent portion. It is formed in the curved portion 11 by cutting and raising, and the height of the insertion port 13 is set higher than the plate thickness of the terminal 9.

  Thus, by providing the insertion port 13 in the curved part 11, the hook-shaped fixing | fixed part 303 can be easily inserted in the insertion port 13, and an assembly property can be improved.

  In such an insertion port 13, a hook-shaped fixing portion 303 is inserted so as to be caught by the insertion port 13 from the tip, and the fixing portion 303 does not come out of the insertion port 13, thereby preventing the terminal 9 from rotating. It can be performed stably.

  In such a bus bar and terminal fixing structure 301, since the fixing portion 303 is formed in a hook shape, the fixing portion 303 is caught by the insertion port 13 in a state where the fixing portion 303 is inserted into the insertion port 13. The fixing portion 303 can be prevented from coming out of the insertion port 13 and the state where the fixing portion 303 is inserted into the insertion port 13 can be maintained with a simple structure.

  Note that, in the bus bar and terminal fixing structure according to the embodiment of the present invention, the case where the engaging portion has the protruding portion and the insertion portion and the case where the engaging portion has the restricting portion are illustrated independently. However, the engaging portion may include a protruding portion, an insertion portion, and a restricting portion.

  In addition, a terminal having a bent part or a terminal having a fixed part formed in a hook shape is not provided with an engaging part. However, the present invention is not limited thereto, and an engaging part may be provided on these terminals. Good.
