Abstract
A noise absorber that can be securely attached around electric wires of various diameters and types, and can be firmly closed without any electric wire caught between the ferrite parts. Wire supports are erected at both sides of a wire-receiving through hole on the inner surfaces of opposed walls of a first case member of the noise absorber. The tips of the wire supports are tilted toward the central axis of the through hole. Almost Y-shaped receptors are formed on the inner surfaces of opposed walls of the second case member for engaging with the tips of the wire supports when the case members are closed. The upper portions of the receptors serve as guide slopes for pressing inwardly the tips of the wire supports, so that the wires are securely pinched between the wire supports.
Claims13
An electric noise absorber comprising:
- a pair of magnetic bodies for surrounding an outer periphery of at least one electric wire to absorb noise current flowing through the electric wire;
- a hollow openable and closable holding case formed by a first and a second hollow case member, both said first and second hollow case members being open on one side for holding one of said pair of magnetic bodies therein, the open sides of said case members being joinable together to form a closed holding case with said pair of magnetic bodies being accommodated therein, and half through holes being formed in opposite ends of said case members, adjacent the open side, such that the half through holes form a through hole extending through the holding case, when the case members are joined together, for holding the electric wire therein;
- at least one wire support member extending from an end portion of said first case member, said support member directly abutting and being resiliently deformed by an opposed surface of said second case member when the case members are joined together;
- and
- an indentation being formed in said second case member for receiving said wire support member when the holding case is closed by joining said two case members;
- wherein, upon joining said case members together, said wire support member is biased by said indentation against a said wire accommodated within the through hole and secures said noise absorber in place at a desired location along that said wire.

- at least one resilient wire support member extending outwardly from said first case member adjacent said half through hole and said wire support member being positionable within and directly engaging with said second case member when said two case members are joined together with one another;
- and
- a guide surface being formed in said second case member for directly biasing said wire support member towards a central axis of said through hole when the holding case is closed by joining the two case members together such that said wire support member is forced against a said wire accommodated within the through hole thereby securing the noise absorber in place at a desired location along a said wire.
