Abstract

A noise suppression member comprises a magnetic core and a case that houses the magnetic core therein. The case comprises a first housing and a second housing that form a housing space to house the magnetic core; a locking mechanism that allows the first housing and the second housing to be fixed to each other through engagement of a claw with a claw receiver; and a support receiver. The claw receiver comprises a movable portion displaceable to a first position and a second position, and the claw is released from the claw receiver when the movable portion is displaced to the second position. The movable portion is nondisplaceable to the second position when the support is inserted into the support receiver.

First claim

The invention claimed is:

1. A noise suppression member comprising:
a magnetic core comprising core parts, each core part including a magnetic material, and formed in an annular shape by combining the core parts; and
a case configured to house the magnetic core, the case comprising:
a first housing and a second housing that comprise respective recesses and form a housing space to house therein the magnetic core when the recesses are arranged opposite to each other;
a locking mechanism that comprises a claw provided to at least one of the first housing or the second housing and a claw receiver provided to at least the other of the first housing or the second housing, and allows the first housing and the second housing to be fixed to each other through engagement of the claw with the claw receiver when the first housing and the second housing are arranged at a position where the housing space is formed; and
a support receiver into which a support capable of supporting the case is inserted when the case is attached to the support,

at least one of the claw or the claw receiver comprising a movable portion displaceable to a first position and a second position, and being configured such that the claw is engaged with the claw receiver when the movable portion is displaced to the first position, whereas the claw is released from the claw receiver when the movable portion is displaced to the second position, and such that the movable portion is nondisplaceable to the second position when the support is inserted into the support receiver; and
a stopper provided in a position between the movable portion and the support with the support being inserted in the support receiver so as to inhibit displacement of the movable portion to the second position by the stopper being held between the movable portion and the support when the movable portion is displaced toward the second position,
wherein the stopper is configured to be displaceable with the movable portion when the movable portion is displaced toward the second position with the support being not-inserted in the support receiver.

2. A noise suppression member, comprising:
a magnetic core comprising core parts, each core part including a magnetic material, and formed in an annular shape by combining the core parts; and
a case configured to house the magnetic core, the case comprising:
a first housing and a second housing that comprise respective recesses and form a housing space to house therein the magnetic core when the recesses are arranged opposite to each other;
a locking mechanism that comprises a claw provided to at least one of the first housing or the second housing and a claw receiver provided to at least the other of the first housing or the second housing, and allows the first housing and the second housing to be fixed to each other through engagement of the claw with the claw receiver when the first housing and the second housing are arranged at a position where the housing space is formed;
a support receiver into which a support capable of supporting the case is inserted when the case is attached to the support;

at least one of the claw or the claw receiver comprising a movable portion displaceable to a first position and a second position, and being configured such that the claw is engaged with the claw receiver when the movable portion is displaced to the first position, whereas the claw is released from the claw receiver when the movable portion is displaced to the second position, and such that the movable portion is nondisplaceable to the second position when the support is inserted into the support receiver; and
a locking part configured to reduce a relative displacement between the support and the support receiver along a pull-out direction of the support from the support receiver by engagement of the locking part with an opening or a recess that is provided in the support when the support is inserted into the support receiver.

3. A noise suppression member, comprising:
a magnetic core comprising core parts, each core part including a magnetic material, and formed in an annular shape by combining the core parts; and
a case configured to house the magnetic core, the case comprising:
a first housing and a second housing that comprise respective recesses and form a housing space to house therein the magnetic core when the recesses are arranged opposite to each other;
a locking mechanism that comprises a claw provided to at least one of the first housing or the second housing and a claw receiver provided to at least the other of the first housing or the second housing, and allows the first housing and the second housing to be fixed to each other through engagement of the claw with the claw receiver when the first housing and the second housing are arranged at a position where the housing space is formed; and
a support receiver into which a support capable of supporting the case is inserted when the case is attached to the support,

at least one of the claw or the claw receiver comprising a movable portion displaceable to a first position and a second position, and being configured such that the claw is engaged with the claw receiver when the movable portion is displaced to the first position, whereas the claw is released from the claw receiver when the movable portion is displaced to the second position, and such that the movable portion is nondisplaceable to the second position when the support is inserted into the support receiver,
wherein the support comprises a portion to be inserted into the support receiver,
the portion to be inserted comprising:
a plate-shaped base part, and
a bent part bent at both ends of the base part and extending in a thickness direction of the base part,

the support having an insertion direction into the support receiver, the insertion direction being perpendicular to both the thickness direction of the base part and a thickness direction of the bent part,

wherein the support receiver comprises a base part opening that allows insertion therein of the base part and a bent part opening that allows insertion therein of the bent part,
wherein the base part opening is configured so as to allow introduction of the base part when the support is oriented in any one of a first orientation and a second orientation, which have a positional relationship where the thickness direction of the base part is reversed by 180 degrees, and
wherein the bent part opening is provided both in a portion to introduce the bent part in a case where the support is oriented in the first orientation and in a portion to introduce the bent part in a case where the support oriented is in the second orientation.

4. The noise suppression member according to claim 2 ,
wherein, when the movable portion is displaced toward the second position with the support being inserted in the support receiver, the support contacts the movable portion to thereby inhibit displacement of the movable portion to the second position.

5. The noise suppression member according to claim 3 ,
wherein, when the movable portion is displaced toward the second position with the support being inserted in the support receiver, the support contacts the movable portion to thereby inhibit displacement of the movable portion to the second position.
