Abstract
Abstract A multicore optical connector includes a connector body having a pair of alignment pin holes and a plurality of optical fiber holes formed therebetween and optical fibers inserted in the optical fiber holes such that the end faces of the optical fibers are exposed through the optical fiber holes. In the multicore optical connector, the optical fiber holes are divided into optical fiber hole groups of a number which coincides with the number of the groups of the optical fibers, and the optical fiber hole groups are separated from one another.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
176 words
A multicore optical connector, comprising: a connector body having top and bottom walls joined to each other by front and rear end walls to define a cavity; a pair of alignment pin holes formed in said front end wall; an opening formed in said rear end wall sized to accommodate a plurality of optical fibers; a plurality of optical fiber holes formed in said front end wall interposed between said alignment pin holes so that end faces of optical fibers accommodated in said opening and extending through the cavity in the connector body are respectively exposed through said optical fiber holes, wherein said optical fiber holes are divided into groups which coincide in number with groups of optical fibers; partition walls extending at least part way between said top and bottom walls and extending longitudinally along the optical fibers to partition said cavity and thereby separate adjacent groups of the optical fibers from each other; and a window formed in one of said top and bottom walls to communicate with the cavity in said connector body.
Claim 2
Dependent Claim
176 words
A multicore optical connector, comprising: a connector body having top and bottom walls joined to each other by front and rear end walls to define a cavity; a pair of alignment pin holes formed in said front end wall; an opening formed in said rear end wall sized to accommodate a plurality of optical fibers; a plurality of optical fiber holes formed in said front end wall interposed between said alignment pin holes so that end faces of optical fibers accommodated in said opening and extending through the cavity in the connector body are respectively exposed through said optical fiber holes, wherein said optical fiber holes are divided into groups which coincide in number with groups of optical fibers; partition walls extending at least part way between said top and bottom walls and extending longitudinally along the optical fibers to partition said cavity and thereby separate adjacent groups of the optical fibers from each other; and a window formed in one of said top and bottom walls to communicate with the cavity in said connector body.
Claim 3
Dependent Claim
25 words
A multicore optical connector according to claim 1, wherein each of the optical fiber hole groups is constituted by two to nineteen optical fiber holes.
Claim 4
Dependent Claim
23 words
A multicore optical connector according to claim 1, wherein the plurality of optical fiber hole groups are constituted by a plurality of columns.
Claim 5
Dependent Claim
18 words
The multicore optical connector of claim 1, wherein said partitions extend fully to said top and bottom walls.
Claim 6
Dependent Claim
35 words
The multicore optical connector of claim 1, wherein said partitions begin at said rear end face for guiding insertion of the optical fiber groups into respective partitioned portion of the cavity in said connector body.
Claim 7
Dependent Claim
23 words
The multicore optical connector of claim 1, wherein said window is sized to extend across all the optical fibers in the connector body.
