Title:
放熱性の高い絶縁電線及びそれを用いたコイル
Document Type and Number:
Japanese Patent JP7216555
Kind Code:
B2
Abstract:
To provide an insulated wire with high heat dissipation that can be applied to voice coils with high heat resistance and high output and other coils requiring heat resistance, and to provide a coil using the same.SOLUTION: In an insulated wire 10 having a metal conductor 1 made of copper or a copper alloy and an insulation layer 2 provided on an outer periphery of the metal conductor 1, the insulation layer 2 is set to contain a non-conductive black pigment 3 in the range of 1.0 to 5.0 mass% in order to solve the above problem. As the black pigment, an oxide-based black pigment such as copper-chromium-manganese composite oxide or iron-chromium composite oxide, or a non-carbon black-based organic pigment is used and it is preferable that a fusion bonding layer 4 is provided on an outer periphery of the insulation layer 2.SELECTED DRAWING: Figure 1
