Abstract: A plug connector comprises a fitting portion to be fitted with another fitting portion of a receptacle connector. In an outer peripheral surface of the fitting portion, an engagement depression is formed. The engagement depression is depressed in a radial direction of the plug connector. A coupling member surrounds the outer peripheral surface of the fitting portion with a predetermined gap kept therebetween. The coupling member is pressed forwards in an axial direction of the plug connector by a coil spring. The receptacle connector further comprises a spring portion, on the free end of which an engagement projection is provided. The engagement projection projects inwardly in the radial direction. The fitting portion of the receptacle connector has a thickness which is substantially equal to the predetermined gap provided for the plug connector.

Abstract: In a battery charger for charging a plurality of battery cells connected in series with each other with a constant current in a batch manner, the present invention is intended to suppress the generation of heat in cell shunt circuit sections which are provided as overheat protective measures for the individual cells. Surplus energy, which is generated in the cell shunt circuit sections by the product of a cell voltage and a shunt current and which becomes a heat generating source, is regenerated to a charger side via a flyback transformer provided in each of the cell shunt circuit sections, thereby suppressing heat generation.

Abstract: In cell shunt circuit sections provided as overcharge protective measures for a plurality of individual cells of a lithium ion battery which are connected in series with one another so as to be charged with a constant current in a batch manner, the present invention is intended to suppress the generation of heat, which would be caused by shunting a charging current to a cell shunt. In each of the cell shunt circuit sections, an energy reservoir acts as a bypass path for bypassing a charging current supplied to a corresponding one of the battery cells so as to be input to the following battery cell, which is provided at a downstream side of the one battery cell, so as to reserve surplus energy obtained from the charging current thus bypassed and regenerate the thus reserved surplus energy to a batch charging line connected with the serially connected battery cells. A switching element is inserted in the bypass path for opening and closing thereof.

Abstract: A nut covering device comprises the following: a cover assembly, including an inner cover, outer cover, and a first constraining mechanism; a second constraining mechanism; and a third constraining mechanism. The first constraining mechanism constrains so that there is no relative motion of the outer cover with respect to the inner cover in an axis direction. The second constraining mechanism constrains so that there is no relative motion of the inner cover with respect to the nut member in the axis direction. The third constraining mechanism constrains so that there is no relative motion of the outer cover with respect to the nut member in the axis direction at least in the removal direction. When a circumferential phase of the inner cover and the outer cover is matched with a predetermined specified phase, second and third constraining mechanisms are released, and the cover assembly can be removed from the nut member.
