A battery attaching/detaching structure for a saddle-type vehicle including: a plurality of substantially rectangular parallelepiped batteries for supplying electric power to a power source of the saddle-type vehicle; a battery case in which the batteries are stored; battery-side terminals provided on lower surfaces of the batteries; and case-side terminals engaged with the battery-side terminals, comprises terminal holders that support the case-side terminals such that the case-side terminals are movable between a connected position where the case-side terminals are connected to the battery-side terminals and a retracted position where the case-side terminals are separated from the battery-side terminals. Between the case-side terminals and the terminal holders, springs for urging the case-side terminals in a direction of pressing the battery-side terminals are disposed. Such battery attaching/detaching structure is capable of limiting the movement of a stored battery and maintaining good electrical connection between a battery-side terminal and a case-side terminal.

Battery attaching/detaching structure for saddle-type vehicle

A battery attachment/detachment structure for a saddle-ride type electric vehicle includes substantially rectangular parallelepiped batteries for supplying electric power to an electric motorcycle, a battery case in which the batteries are housed, a battery-side terminal provided on the bottom surface of each battery, and a case-side terminal engaged with the battery-side terminal. An operation lever for connecting or separating the battery-side terminal and the case-side terminal to/from each other by being operated in the up-and-down direction of a vehicle body, and a locking member for holding the operation lever at a position where the battery-side terminal and the case-side terminal are connected to each other are provided. The locking member regulates the movement of the operation lever towards the upper side of the vehicle body by engaging with the operation lever. The disclosed structure can regulate the movement of housed batteries to maintain excellent electrical connection with a simple configuration.

In a printed circuit board on which a first conductor pattern, a second conductor pattern of smaller area than the first conductor pattern and electronic components are mounted, a gap between a first through-hole connected to the first conductor pattern and a first lead pin inserted therein is defined to be larger than that between a second through-hole connected to the second conductor pattern and a second lead pin. With this, it becomes possible to improve solder rise property, without increasing the number of electronic component production processes or degrading strength with respect to the electronic component.

Printed circuit board

In a method of attaching an electronic component to a printed circuit board by a plurality of screws that are inserted into corresponding through holes cut in the board from a surface of the board and then screwed into corresponding screw holes formed in the component mounted on an opposite surface, the component is screwed onto the board using one of the screws and the component and the screw are soldered onto the board with lead-free solder. After they have been cooled down, the component is screwed onto the board using remaining screws. With this, the strength of the connection between the component and board is improved and also the occurrence of warp of the board and component can be prevented.
