Electric noise absorber

An electric noise absorber for attenuating electric noise on an electric cable, said noise absorber comprising:

• two bodies of magnetic material, each magnetic body having abutment surfaces which contact the abutment surfaces of the other magnetic body to form a magnetic circuit, each of the magnetic bodies having a notch located at one end of the magnetic body;
• two case members which are relatively movable into a closed position, each of the case members including a bottom wall portion and first and second end wall portions extending from the bottom wall portion, the first and second end wall portions being located opposite from each other, the first end wall portion of one case member having a notched opening which cooperates with the corresponding notched opening of the first end wall portion of the other case member to form a first opening through which an electric cable extends when the case members are closed, the second end wall portion of one case member having a notched opening which cooperates with the corresponding notched opening of the second end wall portion of the other case member to form a second opening through which an electric cable extends when the case members are closed;
• each of the case members receiving a magnetic body, each of the case members including a positioner for extending into the notch of the respective magnetic body when the magnetic body is received in the case member, each of the magnetic bodies being movable in its respective case member and being prevented from moving out of the case member when the positioner of the case member extends into the notch of the magnetic body;
• the case members including engagement means for retaining the case members in their closed position;
• and
• a single leaf spring member acting between the bottom wall portion of one of the case members and the magnetic body in the interior space of the one case member and for (i) pressing the abutment surfaces of the magnetic body in the interior space of the one case member into contact with the abutment surfaces of the other magnetic body and (ii) pressing the other magnetic body into contact with the bottom wall portion of the other case member when the case members are closed and the magnetic bodies extend around an electric cable to form a magnetic circuit to absorb electric noise on an electric cable, said single leaf spring member being separate from the magnetic bodies and the case members and being the only spring member associated with said electric noise absorber, said single leaf spring member being located in the interior space of the one case member and having a first portion abutting against the bottom wall portion of the one case member and a second portion abutting against the magnetic body in the interior space of the one case member.

An electric noise absorber for attenuating electric noise on an electric cable, said noise absorber comprising:

• two bodies of magnetic material, each magnetic body having abutment surfaces which contact the abutment surfaces of the other magnetic body to form a magnetic circuit, each of the magnetic bodies having a notch formed therein, at least one of the magnetic bodies having a rectangular contact side surface area, the rectangular contact side surface area of the one magnetic body having first and second end portions located adjacent to opposite ends of the one magnetic body and a central portion located between the opposite end portions;
• two case members which are relatively movable between an open position and a closed position, each of the case members including a bottom wall portion and side wall portions extending from the bottom wall portion to define an interior space of the case member;
• each of the case members receiving a magnetic body, each of the case members including a positioner for extending into the notch of the respective magnetic body when the magnetic body is received in the case member, each of the magnetic bodies being prevented from moving out of the interior space of its respective case member when the positioner of the case member extends into the notch of the magnetic body, one of the case members having a rectangular inner side surface area which faces toward the other case member when the case members are in their closed position, the rectangular inner side surface area of the one of the case members being disposed on the bottom wall portion of the one of the case members;
• the case members including engagement means for retaining the case members in their closed position;
• and
• a single leaf spring member acting between the bottom wall portion of one of the case members and the magnetic body in the interior space of the one case member and for (i) pressing the abutment surfaces of the magnetic body in the interior space of the one case member into contact with the abutment surfaces of the other magnetic body and (ii) pressing the other magnetic body into contact with the bottom wall portion of the other case member when the case members are closed and the magnetic bodies extend around an electric cable to form a magnetic circuit to absorb electric noise on an electric cable, said single leaf spring member being separate from the magnetic bodies and the case members and being the only spring member associated with said electric noise absorber, said single leaf spring member being located in the interior space of the one case member and having a central portion abutting against the bottom wall portion of the one case member and first and second end portions abutting against the magnetic body in the interior space of the one case member, said single leaf spring member having a rectangular configuration with the central portion disposed between the first and second end portions of said spring member, said single leaf spring member having a bowed configuration, the first end portion of said single leaf spring member being disposed in abutting engagement with the first end portion of the rectangular contact side surface area of the one magnetic body and being spaced from the rectangular inner side surface area of the one of the case members when the case members are in their open position, the second end portion of said single leaf spring member being disposed in abutting engagement with the second end portion of the rectangular contact side surface area of the one magnetic body and being spaced from the rectangular inner side surface area of the one of the case members when the case members are in their open position, the central portion of said single leaf spring member being disposed in abutting engagement with the rectangular inner side surface area of the one of the case members and being spaced from the rectangular contact side surface area of the one magnetic body when the case members are in their open position, said single leaf spring member pressing the notch on the one magnetic body against the positioner when the case members are in their open position, said single leaf spring member pressing the abutment surfaces on the one magnetic member against the abutment surfaces on the other magnetic member when the case members are in their closed position, the one magnetic member being moved relative to the one case member against the influence of said single leaf spring member during movement of the case members toward their closed position, the first and second end portions of said single leaf spring member being moved toward the rectangular inner side surface area of the one case member during movement of the case members toward their closed position, the central portion of the rectangular contact side surface area of the one magnetic body being moved toward the central portion of said single leaf spring member during movement of the case members toward their closed position.
