摘要： A control section sets a positive side switching element of a positive side detection section and a negative side switching element of a negative side detection section to ON, thus outputting an ON signal. When the switching elements are set ON, a predetermined current outputted from a positive side constant current source and a negative side constant current source, or a portion of this current, flows through detection resistors. A ground fault decision section decides whether a ground fault has occurred in the positive or the negative side of a direct current power source, based upon the value of an output voltage detected by a positive side voltage detector, or upon the value of an output voltage detected by a negative side voltage detector. Ground faults are accurately detected with a simple structure.

摘要： To provide a technique by which an accumulated tolerance caused by the arrangement of terminal fittings is eliminated to improve the workability in a multipole cell-voltage detection connector. When all of receptacle terminals (94) are inserted into receptacle insertion groove parts (22), each of the receptacle terminals (94) is buckled at a bending hole (97) and a mark-off part (98) formed as a boundary of a receptacle root part (95) and a receptacle front part (96). Because the receptacle insertion groove parts (22) are formed in a state where there is substantially no tolerance, the terminal pitch tolerance correction housing (10) is fitted to receptacle units (90), and the receptacle terminals (94) (receptacle front parts (96)) protruded from the receptacle insertion groove parts (22) toward a bottom inner surface (15) are corrected to a state where there is no tolerance.
