Abstract
A reel for a taped series of electronic components includes first and second reel halves. The first reel half includes a first protruding portion and a first flange portion extending radially outward from an end of the first protruding portion. The second reel half includes a second protruding portion and a second flange portion extending radially outward from an end of the second protruding portion. The first and second flange portions each include an outermost end extending in a different direction from the radial direction.
Claims18
A reel for a taped series of electronic components, the taped series of electronic components being configured to be wound on the reel, the reel comprising:
- a first reel half including a plate material;
- and
- a second reel half including a plate material and butted against the first reel half;
- the first reel half including:
- a first protruding portion protruding toward the second reel half and including a cylindrical circumferential wall and a top plate;
- and
- a first flange portion in a disk shape extending outward in a radial direction from an end of the first protruding portion;
- the second reel half including:
- a second protruding portion protruding toward the first reel half and including a cylindrical circumferential wall and a top plate;
- and
- a second flange portion in a disk shape extending outward in the radial direction from an end of the second protruding portion;
- wherein
- a top surface of the top plate of the first protruding portion including an axis of the first reel half and a top surface of the top plate of the second protruding portion including an axis of the second reel half are joined together to provide a core defined by the first protruding portion and the second protruding portion;
- a juncture between the circumferential wall of the first protruding portion and the first flange portion has a radius of curvature larger than a radius of curvature of a juncture between the top plate of the first protruding portion and the circumferential wall of the first protruding portion;
- the radius of curvature of the juncture between the circumferential wall of the first protruding portion and the first flange portion is about 0.1 mm or more and less than about 0.6 mm;
- a juncture between the circumferential wall of the second protruding portion and the second flange portion has a radius of curvature larger than a radius of curvature of a juncture between the top plate of the second protruding portion and the circumferential wall of the second protruding portion;
- the radius of curvature of the juncture between the circumferential wall of the second protruding portion and the second flange portion is about 0.1 mm or more and less than about 0.6 mm;
- an outer edge of the first flange portion extending in an out-of-plane direction different from an in-plane direction of the first flange portion;
- and
- an outer edge of the second flange portion extending in an out-of-plane direction different from an in-plane direction of the second flange portion.
