Abstract: An optical fiber connection structure which reduces MPI in the use of an optical fiber with a bend resistance improved by forming holes in the fiber, and a single-mode fiber which reduces MPI are provided. A second cladding portion of a second single-mode fiber 20 includes holes 28, and thus, the second single-mode fiber 20 has low bending loss. A portion of the second single-mode fiber 20 connected to a first single-mode fiber 10a is made solid by filling corresponding portions of the holes 28 over the length L0, and light in a mode LP11 is significantly attenuated in this portion, thereby reducing MPI.

In at least one fiber end, the second cladding has been removed by mechanical processing so that the at least one fiber end is formed by the core and the first cladding.

Abstract: A connector housing that is reduced in size in correspondence with reduction in size of a terminal. When a connecting terminal to which an electric wire and a waterproof sealing member are attached is inserted into a terminal accommodating hole from an terminal insertion opening, a step of the waterproof sealing member abuts against a step of the terminal insertion opening and also a taper surface meets a taper surface, preventing water from entering the terminal accommodating hole from the backside. In this state, the waterproof sealing member is pressed toward a connector housing by a rear holder to prevent the waterproof sealing member from falling out of position. Thus, because the terminal insertion opening is sealed, with a part of the waterproof sealing member placed outside the connector housing, the lateral width and vertical width of the terminal accommodating hole can be set to the magnitudes that substantially allow the connecting terminal to pass through the hole.

Abstract: A pivoting lever has tongue-like movable pieces formed in a squared U-shape on both side faces of a cover member, and locking claws at intermediate parts of the movable piece. A pivoting lever is pivotally supported on a support pin of the cover member. Circular arc-shaped cam grooves are formed in a lever body part, and locking holes engaging locking claws are formed in the lever body part. When a mating housing is pressed into a housing and the lever is pivoted, the cam grooves drive a driven pin and pull the mating housing toward the housing. The lever contacts the locking claws, and pivots the locking claws while pushing them down. When the housings are joined, the locking claws returned to the original positions fitted into the locking holes, setting the lever to a locked state, thereby disabling further rotation and reverse rotation of the lever.
