Abstract: Disclosed is a battery pack and a mechanism for connecting the battery pack (40) that provide increased freedom for detachment and removal from an electric/electronic device (10). Since a head (46), wherein a plurality of terminals are so provided inside individual slits as not to be exposed externally, is connected to a battery interface (76) that is a part of a personal computer and that has a plurality of plugs, the terminals of the battery pack are electrically connected to the corresponding plugs. Since all the slits of the head (46) are so formed that each extends fully through the head (46) in the direction of the thickness of the battery pack (40), and so that each is open at the top, at the bottom, and at one side, the head (46) can be connected to the battery interface (76) from the top, from the bottom, or from the side of the battery interface (76).

Abstract: PURPOSE: To easily accommodate cables by providing an engaging mechanism for removably engaging the end part of the cable to a body. CONSTITUTION: An engaging mechanism 6 is formed of a DC terminal 3 at the end part of a DC cable 2 and a recess 100 of a first flange 1A. A recess 10 is formed by cutting out one side of a first flange 1A and a DC connector socket 33 of the DC terminal 3 is just accommodated in the recess 100. Moreover, a window 9 communicated with the recess 100 is formed to the first flange 14, along the longitudinal direction of the recess 100. When a DC connector socket 33 is to be accommodated in the recess 100, the DC connector socket 33 is placed within the recess 100, while the end point 31 of plug is inserted to the window 9. Thereby the cables can be accommodated easily.

Abstract: PROBLEM TO BE SOLVED: To inform used equipment such as a charger or a batter of its abnormality and prevent overcharge or overdischarge by changing the temperature detection output into the signal equivalent abnormal temperature, when this protective circuit detects the abnormality of the charge condition or discharge condition of a secondary battery. SOLUTION: Secondary batteries 1 and 2 are charged by fixed voltage charge method used for, for example, a lithium secondary battery, a lead battery, etc. The batteries 1 and 2 are connected in series, and n-channel FETs 3 and 4 constituting first and second switch elements are connected in series to the charge/discharge circuit. The parasitic diodes D1 and D2 of the FETs 3 and 4 get in forward direction at the time of charge and discharge. In a protective circuit, the + terminal, to the + terminal of the battery 1, and the - terminal, to the source of the FET 3, and a thermistor 1, between the outer terminal T and the - terminal, are connected. The thermistor 11 operates overcharge or overdischarge preventive circuits 5 or 6 through a transistor 12 and an abnormality detection circuit 10 so as to charge or discharge it properly when the temperature during charge or discharge deviates from the specified range.
