Abstract
An adapter includes a tubular body having a tubular shape and surrounding a pair of ferrules over half a circumference or more with a ling along a first direction as an axis. The tubular body includes a guide extending in the first direction and engaging with side surfaces of the ferrule, and a slit formed from one end to the other end in the first direction.
Claims11
An optical connection structure comprising:
- an adapter that holds a pair of ferrules facing each other, the adapter comprising:
- a tubular body having a substantially rectangular tubular shape and surrounding the pair of ferrules such that the tubular body surrounds half or more of an outer peripheral length of each of the ferrules having a longitudinal axis along a first direction,
- wherein the tubular body includes:
- a first inner peripheral surface,
- a second inner peripheral surface that is parallel to the first inner peripheral surface and faces the first inner peripheral surface along a second direction that is orthogonal to the first direction,
- a third inner peripheral surface that is orthogonal to the first inner peripheral surface and to the second inner peripheral surface,
- a fourth inner peripheral surface that is parallel to the third inner peripheral surface that faces the third inner peripheral surface along a third direction orthogonal to the first direction and the second direction,
- a first guide that protrudes from the first inner peripheral surface toward the second inner peripheral surface, and
- a second guide that protrudes from the second inner peripheral surface toward the first inner peripheral surface,
- wherein a top surface of the tubular body and the third inner peripheral surface define an upper wall of the tubular body, and
- wherein a slit is formed in the upper wall and extends in the first direction from a first end to a second end opposite the first end of the tubular body;
- and
- the pair of ferrules held in the tubular body of the adapter, wherein;
- each of the pair of ferrules has a first engaging portion on a first side surface and a second engaging portion on a second side surface opposing the first side surface,
- the first engaging portion of each of the pair of ferrules engages with the first guide,
- the second engaging portion of each of the pair of ferrules engages with the second guide, and
- the pair of ferrules are biased in a direction in which the ferrules face each other via a pair of springs respectively disposed on a rear end side of each of the ferrules.
