Spacer fixing structure
Disclosed herein is a spacer fixing structure including a core member constituting a core to be wound with a coil; and a plate spacer fixed to the core member. The spacer has a loop shape. A communication groove is formed in at least one surface of front and back surfaces of the spacer, and extends radially to communicate with inner and outer peripheries of the spacer. A region of the at least one surface of the spacer other than a grooved portion is left as a flat surface. At least the flat surface of the spacer is adhered to the core member via an adhesive layer made of an adhesive.
1. A spacer fixing structure comprising:
a core member constituting a core to be wound with a coil; and
a plate spacer fixed to the core member, wherein
the spacer has a loop shape, at least one loop-shaped groove extending along a circumference of the spacer is formed in that at least one surface of the spacer, wherein an adhesive layer is extruded into the loop-shaped grove,
a communication groove is formed in at least one surface of front and back surfaces of the spacer, and extends radially to communicate with inner and outer peripheries of the spacer,
a region of the at least one surface of the spacer other than a grooved portion is left as a flat surface, and
at least the flat surface of the spacer is adhered to the core member via the adhesive layer made of an adhesive.
2. The structure of claim 1 , wherein
the spacer has a ring shape, and
the loop-shaped groove is coaxial with the spacer.
3. The structure of claim 1 , wherein
the at least one loop-shaped groove includes a plurality of loop-shaped grooves.
