Document Type and Number:
WIPO Patent Application WO/2024/070257
Kind Code:
A1
Abstract:
The objective of the present invention is to cause both of two core members to adopt a state of being coupled together with a sufficient magnetic coupling force, while achieving a reduction in size. This clamp sensor comprises a first core member 21 constituting a circumferential-direction portion of a magnetic core 20 that is arranged in a ring shape, and a second core member 22 constituting another portion thereof, the clamp sensor being configure such that: first projecting portions that project out in the circumferential direction are provided at circumferential-direction tip ends P21a and P21b of the member 21, and second projecting portions that project out in the circumferential direction are provided at circumferential-direction tip ends P22a and P22b of the member 22; and in a closed state, the first projecting portions on the tip end P21a side and the second projecting portions on the tip end P22a side overlap in an insertion direction, and the first projecting portions on the tip end P21b side and the second projecting portions on the tip end P22b side overlap in the insertion direction.
