Abstract
A shield conductor Wa comprises: a metallic pipe 20, a wire 10 to be inserted into the pipe 20, and a groove-like fitting member 22 provided in the pipe 20 as extending along the direction of axis of the wire 10, and at the same time, attached tightly to the circumference of the wire. With the inner surface of the groove-like fitting member 22 in the pipe 20 attached tightly to the circumference of the wire 10, the heat generated in the wire 10 is transmitted directly to the pipe 20, and then released to the air from the circumference of the pipe 20. This improves radiation performance of the shield conductor Wa.
Claims17
A shield conductor comprising:
- a metallic pipe,
- a wire to be inserted into the pipe, and
- a groove-like fitting member which is provided in the pipe and extends along the direction of axis of the wire, and is securely attached to the circumference of the wire,
- wherein the pipe is formed by combining a plurality of plate shaped composing members having the groove-like fitting member, and
- wherein a plurality of the groove-like fitting members are formed in each plate shaped composing member, and a portion positioned between the groove-like fitting members in the plate shaped composing member and the groove-like fitting members in the other plate shaped composing member is in a magnetically-insulated condition.
A shield conductor comprising:
- a metallic pipe,
- a wire to be inserted into the pipe, and
- a groove-like fitting member which is provided in the pipe and extends along the direction of axis of the wire, and is securely attached to the circumference of the wire,
- wherein the pipe is formed by combining two plate shaped composing members overlapped in the plate thickness direction, and one plate shaped composing member is a flat plate, while the other plate shaped composing member is formed with the groove-like fitting member, and
- wherein a plurality of the groove-like fitting members are formed in the plate shaped composing member formed with the groove-like fitting member, and a portion positioned between the groove-like fitting members in the plate shaped composing member is in a magnetically-insulated condition.
A shield conductor comprising:
- a metallic pipe,
- a wire to be inserted into the pipe, and
- a groove-like fitting member which is provided in the pipe and extends along the direction of axis of the wire, and is securely attached to the circumference of the wire,
- wherein the pipe is formed with one plate shaped composing member folded back approximately at the center, and
- wherein a plurality of the groove-like fitting members are formed in the plate shaped composing member, and a portion positioned between the groove-like fitting members in the plate shaped composing member is in a magnetically-insulated condition.
A shield conductor manufacturing method, comprising the steps of:
- forming a plurality of metallic plate shaped composing members having a plurality of groove-like fitting members,
- externally fitting the groove-like fitting members to a wire, and
- constituting a pipe by combining the plate shaped composing members so as to enwrap the wire and by bringing the plurality of plate shaped composing members together so that a portion positioned between the groove-like fitting members in the plate shaped composing member and the groove-like fitting members in the other plate shaped composing member is in a magnetically-insulated condition.
