Claims

[Scope of utility model registration request]

A pair of holders in which current detecting units having divided magnetic cores are housed are supported by being biased in the opening direction by a spring member interposed in a support shaft, so that the magnetic cores are brought into abutment. The holders are formed so that the end faces can come into contact with and separate from each other, and are always biased to press the abutting end face side of the magnetic core by a spring member interposed on both sides of either one of the holders. In addition, a wing-shaped clamping piece having a hook extending from the butt end face is attached, and the clamping piece is attached to both sides of the holder on the other side when the holder is closed. An opening/closing mechanism for a clamp sensor, characterized in that a clamped part is formed in a positional relationship that allows the holder to be latched to the latching part, thereby making it possible to maintain a forcibly closed state between the holders.
