Abstract
An optical connector includes: a ferrule that includes a connection end surface, and a fiber hole into which an optical fiber is configured to be inserted up to the connection end surface; a spring that is disposed on a rear side of the ferrule that is opposite to a front side that is a side on which the connection end surface is disposed in a longitudinal direction of the fiber hole; a spring push that sandwiches the spring with the ferrule and through which the optical fiber is inserted in the longitudinal direction; and a housing that accommodates the ferrule and the spring and that is engaged with the spring push such that the ferrule is biased to the front side by the spring. The optical fiber is configured to be inserted into and removed from the spring push.
Claims8
An optical connector comprising:
- a ferrule that comprises:
- a connection end surface;
- and
- a fiber hole into which an optical fiber is configured to be inserted up to the connection end surface;
- a spring that is disposed on a rear side of the ferrule that is opposite to a front side that is a side on which the connection end surface is disposed in a longitudinal direction of the fiber hole;
- a spring push that sandwiches the spring with the ferrule and through which the optical fiber is inserted in the longitudinal direction;
- and
- a housing that accommodates the ferrule and the spring and that is engaged with the spring push such that the ferrule is biased to the front side by the spring, wherein
- the spring push comprises:
- a first member comprising a spring holding part that is inserted into and fitted inside a rear end of the spring and that holds the rear end of the spring;
- and
- a second member that:
- accommodates the first member within,
- supports the first member, and
- is engaged with the housing,
- the first member is configured to move with respect to the second member, and
- the optical fiber is configured to be inserted into and removed from the second member.
