Abstract
Abstract The optical connector of this invention consists of a plug housing 20 having a joining cavity 22 with bosses 22a and 22b formed on the inside walls 20a, an optical fiber protection member 40 having a plate-shaped base 42 which can be inserted in and pulled out from the joining cavity 22, and a header housing 60 having a joining protrusion 62 fitting in the joining cavity 22. When the plug housing 20 and the header housing 60 are not connected, the front end of the optical fiber 24 is located in the through opening 42a of the optical fiber protection member 40, thus protecting the optical fiber 24 from damage. Upon mating of the header housing 60 with the plug housing 20, the optical fiber protection member 40 is urged back into the plug housing 20 to expose the optical fiber 24.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
An optical connector comprising: A first housing having a joining cavity with bosses formed on its inside walls extending in a mating direction, an optical fiber protection member having a base with a through opening through which an optical fiber is inserted, at least one leg extending from the base in the mating direction and being latchable with the bosses of the first housing, a second housing having a joining protrusion fitting into the joining cavity of the first housing, and thrust protrusions formed on an outside wall; whereby in an unmated position, the optical fiber protection member is located in the first housing so that the front end of the optical fiber is inside said through opening because the legs and the bosses are engaged, and in a mated position, the legs and the bosses are released from each other due to the fact that when the joining protrusion is inserted in the joining cavity, the thrust protrusions spread the legs.
Claim 2
Dependent Claim
162 words
An optical connector comprising: A first housing having a joining cavity with bosses formed on its inside walls extending in a mating direction, an optical fiber protection member having a base with a through opening through which an optical fiber is inserted, at least one leg extending from the base in the mating direction and being latchable with the bosses of the first housing, a second housing having a joining protrusion fitting into the joining cavity of the first housing, and thrust protrusions formed on an outside wall; whereby in an unmated position, the optical fiber protection member is located in the first housing so that the front end of the optical fiber is inside said through opening because the legs and the bosses are engaged, and in a mated position, the legs and the bosses are released from each other due to the fact that when the joining protrusion is inserted in the joining cavity, the thrust protrusions spread the legs.
Claim 3
Dependent Claim
33 words
The optical connector as recited in claim 1 wherein the at least one leg is L-shaped having a long portion and a short portion, the leg engages the bosses along the short portion.
Claim 4
Dependent Claim
15 words
The first housing as recited in claim 1 wherein the bosses are rectangular in shape.
Claim 5
Dependent Claim
17 words
The second housing as recited in claim 1 wherein the thrust protrusions have a plurality of corners.
Claim 6
Dependent Claim
30 words
The second housing of claim 4 wherein the thrust protrusions are positioned such that two of the corners of each protrusion lie on an axis extending along the mating direction.
Claim 7
Dependent Claim
148 words
A first housing of an optical connector, containing an optical fiber for mating with a second housing retaining an optical element, characterized by the fact that it has a joining cavity with bosses formed on the inside walls extending in a mating direction, and that it retains an optical fiber inserted in said joining section along the mating direction and secures said fiber in an inserted position; it is furnished with an optical fiber protection member consisting of a base with a through opening through which said optical fiber is inserted, having at least one leg extending from the base in the mating direction and latching with said bosses of the first housing, said optical fiber protection member being movable between an inserted position and a withdrawn position due to the interaction of the bosses with the legs during mating and unmating of the first and second housings.
Claim 8
Dependent Claim
148 words
