Abstract

Abstract The present invention relates to an optical fiber connector comprising: an internal member (10) including a block (10c) having a hole to receive a sheath portion on an end of an optical fiber cord and an optical fiber exposed therefrom, and cantilevers (12) provided on the side walls of the block (10c) to extend along the walls, which cantilevers (12) respectively have projections (12a) protruding inward as well as projections (13) which protrude outward when no force is applied thereon. The optical fiber connector comprises further an external member (20) including an opening (20a) through which said optical fiber cord is inserted, and openings or recesses (22) which engage with the projections on the cantilevers of the internal member (10) on the side wall thereof to be fit into the block of the internal member axially and slidably. The internal member (10) is inserted into the external member (20) gradually, the projections (12a) project therethrough to thereby prevent said external member from receding therefrom.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 143 words
An optical fiber connector comprising: an internal member including a block having a hole to receive a sheath portion on an end of an optical fiber cord and an optical fiber exposed therefrom, and cantilevers provided on the side walls of the block to extend along the walls which cantilevers respectively have projections protruding inward as well as projections which protrude outward when no force is applied thereon; and an external member including an opening through which said optical fiber cord is inserted, and openings or recesses which engage with the projections on the cantilevers of the internal member on the side wall thereof to be fit into the block of the internal member axially and slidably; Wherein when the internal member is being inserted into the external member gradually, the projections project therethrough to thereby prevent said external member from receding therefrom.
Claim 2
Dependent Claim 143 words
An optical fiber connector comprising: an internal member including a block having a hole to receive a sheath portion on an end of an optical fiber cord and an optical fiber exposed therefrom, and cantilevers provided on the side walls of the block to extend along the walls which cantilevers respectively have projections protruding inward as well as projections which protrude outward when no force is applied thereon; and an external member including an opening through which said optical fiber cord is inserted, and openings or recesses which engage with the projections on the cantilevers of the internal member on the side wall thereof to be fit into the block of the internal member axially and slidably; Wherein when the internal member is being inserted into the external member gradually, the projections project therethrough to thereby prevent said external member from receding therefrom.
Claim 3
Dependent Claim 22 words
The optical fiber connector, as claimed in Claim 1, wherein said optical fiber cord is secured with said projections of the cantilevers.
Claim 4
Dependent Claim 25 words
The optical fiber connector, as claimed in Claim 1, further including an optical element fixed on an end of said block of said internal member.
Claim 5
Dependent Claim 31 words
The optical fiber connector is claimed in Claim 1, wherein said internal member is structured to have another block which is identical to said block and is formed in continuation thereto.
