Abstract: A charging device for a battery of a vehicle includes an insulation resistance detecting circuit, a charging circuit, a leak current detecting circuit and a decoupling circuit. The insulation resistance detecting circuit includes a coupling capacitor, and is disposed between the battery and a vehicle body for detecting an insulation resistance between the battery and the vehicle body. The charging circuit converts an alternating current supplied from an alternating current source into a direct current and charges the battery in a state without insulting the input terminal and the output terminal and in a state where the vehicle body is coupled to an earth. The leak current detecting circuit detects a leak current between the charging circuit and the earth. The decoupling circuit decouples the insulation resistance detecting circuit from one of the battery and the vehicle body during a charging of the battery.

Abstract: A terminal cover includes a cover body equipped with a curved portion and a base portion. The curved portion has formed therein a pair of claws diametrically opposed to each other. The claws are arranged at an interval away from each other. The interval is selected to be smaller than the width of the terminal and increased by elastic deformation of the cover body arising from installation of a terminal in the terminal cover, so that the claws retain the terminal. This structure enables the terminal cover to be simple and small-sized and facilitates installation of the terminal in the terminal cover without being scraped by the terminal when inserted into the terminal cover.

Abstract: A terminal cover includes a lid and a cover body. The lid is rotatable around a hinge to open or close the cover body. An assembly of the cover body and the lid closed has a first side wall and a second side wall. A shoulder side wall that is at least one of the first and second side walls has a shoulder. The shoulder side wall is equipped with a first snap-fit and a second snap-fit. The first snap-fit is located closer to the hinge than the shoulder is, while the second snap-fit is located farther away from the hinge than the shoulder is. If the second snap-fit is undesirably unlocked, the shoulder serves to block transmission of resultant deflection of a portion of the shoulder side wall to the first snap-fit, thereby eliminating a risk that the first snap-fit may be accidently undone by the undesirable unlocking of the second snap-fit.
