Abstract

Abstract An optical fiber connector comprises a retaining plate (20, 60, 85, 95, 113, 142, 173) made of comparatively thin sheet metal and having a slot (22, 61, 86, 113a, 173a) formed therein which has an opening at one end, the opening having a width smaller than an outer diameter of an optical fiber jacket (5a, 101b, 103a) and larger than a diameter of a fiber optic core (5b, 101a, 103d). The retaining plate is inserted in a connector body (10, 70, 80, 90, 111, 141, 171) at almost a right angle to an axial direction of the optical fiber cable (5, 101, 103) disposed in the connector body with the opening of the slot facing toward the optical fiber cable, and the retaining plate is pressed into the connector body and the jacket of the original fiber cable in the connector body.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 195 words
A connector (1,7) for connection to an optical fiber cable (5) having an optical fiber core (5b) and an outer jacket (5a), the connector (1,7) comprising a housing (10,70) having a bore (13) for receiving an end of the optical fiber cable (5), a slot (14,15,71) in the housing (10,70) communicating with the bore (13), a retaining member (20,60) in the form of a plate (21,60) for retaining the optical cable in the bore (13), said plate having a slot (22,61) therein having edges for engagement with the optical cable (5), the retaining member (20,60) being constructed to be pressed into the housing slot (14,15,71) to extend partly into the bore (13) so that the edges of the slot (22,61) in the retaining member (20,60) penetrate the outer jacket (5a) of the cable (5), securing means being provided on the retaining member (20,60) for securing it in the housing (10,70); characterized in that said securing means are resilient projection means (23) which extend from said plate (21,60) outwardly of the plane thereof, and which move parallel to the axis of the bore (13) when the plate (21,60) is being received in the housing slot (14,15,71).
Claim 2
Dependent Claim 21 words
A connector as claimed in claim 1, characterized in that retaining means (20) comprises parallel plates(21) interconnected by a further plate.
Claim 3
Dependent Claim 32 words
A connector as claimed in claim 1 or 2, characterized in that the bore (13) has a portion (13b) of reduced diameter for receiving an exposed end of the fiber core (5b).
Claim 4
Dependent Claim 42 words
A connector as claimed in claim 1, 2, or 3, characterized in that a photoelectronic element (6) is aligned with the bore (13) for alignment with a light transmitting end of an optical cable (5) to be received in the bore (13).
