Embodiment Construction

[0035] Now refer to the attached Figures 1 to 5 , an embodiment of the electrical junction box according to the present invention will be described below.

[0036] The electric junction box is installed in the motorcycle such that the electric junction box is inclined in the motorcycle.

[0037] as attached figure 1 As shown in and 2, the electrical junction box may include a cover assembly having an upper cover 10 and a lower cover 11. The bus bar lamination unit 18 and the printed circuit board unit 15 can be housed in the cover assembly so that they are disposed from the upper cover 10 to the lower cover 11, and the bus bars 16 and insulating plates 17 are alternately laminated in the bus bar lamination unit , the printed circuit board unit includes a first printed circuit board 13 , a spacer 12 and a second printed circuit board 14 .

[0038] The shorter-sized fixing rod 10x may be integrally formed with the inner surface of the top wall 10a of the upper cover 10, and...

Abstract

An electrical junction box reduces the number of components to be contained in an electrical junction box and simplifies a structure of the box. The electrical junction box has a casing assembly including an upper casing and a lower casing. A laminated unit including bus bars and insulation plates is contained in the upper casing, while a first printed circuit board, a second printed circuit board and a spacer made of an insulation resin material are contained in the lower casing. The first printed circuit board is disposed on one side of the spacer, while the second printed circuit board is disposed on the other side of the spacer. Shorter size fixing bars and longer size fixing bars project from an inner surface on a top wall of the upper casing. The shorter size fixing bars penetrate the laminated unit, first printed circuit board and spacer. Screws are inserted upward into the shorter size fixing bars via through-holes in the spacer to secure the unit, first printed circuit board, and spacer to the shorter bars. Longer size fixing bars penetrate the laminated unit, first printed circuit board, spacer, second printed circuit board, and lower casing. Screws are inserted upward into the longer size fixing bars via through-holes in the lower casing to secure the unit, first and second printed circuit boards, spacer, and lower casing to the longer bars.

Description

technical field [0001] The present invention relates to an electric junction box mounted on a motorcycle, and more particularly, to an electric junction box that accommodates a printed circuit board, can reduce the number of parts to be accommodated, can simplify the structure, and can achieve slimming and miniaturization the goal of. Background technique [0002] With the rapid increase of electrical components to be installed on motorcycles, electrical junction boxes to be installed on motorcycles need to accommodate electrical and electronic components together with conventional ordinary laminated units including busbars and insulating plates Several printed circuit boards mounted on it. Since the number of components to be installed in the electrical junction box has increased, the configuration of the electrical junction box tends to be complicated and increased in size. [0003] For example, as the appended Figure 6 As shown in , the electrical junction box disclose...
