Optical-connector-incorporating plug
In an optical-connector-incorporating plug accommodating and holding an optical connector in a barrel at a front end thereof and accommodating, in the barrel, an extra length portion of an optical fiber extending from an optical cable to the optical connector, the extra length portion bends as the optical connector is moved toward a back end of the barrel when the optical connector is connected to a mating receptacle; the distance from the position where the optical connector is held to the outer wall of the barrel depends on the direction, among the directions orthogonal to the direction in which the optical connector is moved; and a guide portion guiding the bend of the extra length portion in a direction other than the direction where the distance to the outer wall of the barrel is the shortest is formed in the barrel. The optical-connector-incorporating plug can be reduced in size.
1. An optical-connector-incorporating plug accommodating and holding an optical connector in a barrel at a front end thereof and accommodating, in the barrel, an extra length portion of an optical fiber extending from an optical cable to the optical connector,
the extra length portion bending as the optical connector is moved toward a back end of the barrel when the optical connector is connected to a mating receptacle,
the outer shape of the barrel being quadrilateral at the direction orthogonal to the direction in which the optical connector is moved, and
a guide portion guiding the bend of the extra length portion in a diagonal direction of the quadrilateral shape being formed in the barrel.
2. The optical-connector-incorporating plug according to claim 1 , wherein the guide portion is a groove-shaped accommodation space for accommodating the bend of the extra length portion.
3. The optical-connector-incorporating plug according to claim 1 , wherein the guide portion is a slit that allows the extra length portion to pass therethrough.
4. The optical-connector-incorporating plug according to claim 1 ,
wherein the barrel further accommodates and holds an optical connector identical to the optical connector in a manner identical to that for the optical connector, and
the extra length portions up to the two optical connectors are disposed to cross each other.
5. The optical-connector-incorporating plug according to claim 2 ,
wherein the barrel further accommodates and holds an optical connector identical to the optical connector in a manner identical to that for the optical connector, and
the extra length portions up to the two optical connectors are disposed to cross each other.
6. The optical-connector-incorporating plug according to claim 3 ,
wherein the barrel further accommodates and holds an optical connector identical to the optical connector in a manner identical to that for the optical connector, and
the extra length portions up to the two optical connectors are disposed to cross each other.
