Abstract
Abstract A plug-type connector is provided for one end of a fiber-optic cable, which cable includes at least one optical fiber surrounded by a fiber sheath, a strand-type strain-relief element and a cable sheath. The plug-type connector includes a ferrule with a central longitudinal bore for receiving an unsheathed end of the optical fiber, a ferrule-holder for receiving a rear region of the ferrule, and a casing in which the ferrule-holder is mounted. The ferrule holder is axially movable in the casing against a restoring force. The ferrule-holder and the casing each include central openings through which the optical fiber and the fiber sheath are movable into the cable sheath. The casing includes a receiving space into which an end of the strain-relief element can be introduced and immobilized by adhesive bonding and/or sealing. The receiving space is separated in a liquid-tight manner from the central opening in the casing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A plug-type connector for one end of a fiber-optic cable, which cable includes at least one optical fiber surrounded by a fiber sheath, a strand-type strain-relief element and a cable sheath, said plug-type connector comprising: a ferrule with a central longitudinal bore for receiving an unsheathed end of the optical fiber; a ferrule-holder for receiving a rear region of said ferrule; a casing in which said ferrule-holder is mounted, said ferrule holder being axially movable in said casing against a restoring force, said ferrule-holder and said casing each including central openings through which the optical fiber and the fiber sheath are movable into the cable sheath; and means for fastening an end of the strain-relief element to the casing, including a receiving space in said casing into which the end of the strain-relief element can be introduced and immobilized by adhesive bonding and/or sealing, said receiving space being separated in a liquid-tight manner from the central opening in said casing.
Claim 2
Dependent Claim
160 words
A plug-type connector for one end of a fiber-optic cable, which cable includes at least one optical fiber surrounded by a fiber sheath, a strand-type strain-relief element and a cable sheath, said plug-type connector comprising: a ferrule with a central longitudinal bore for receiving an unsheathed end of the optical fiber; a ferrule-holder for receiving a rear region of said ferrule; a casing in which said ferrule-holder is mounted, said ferrule holder being axially movable in said casing against a restoring force, said ferrule-holder and said casing each including central openings through which the optical fiber and the fiber sheath are movable into the cable sheath; and means for fastening an end of the strain-relief element to the casing, including a receiving space in said casing into which the end of the strain-relief element can be introduced and immobilized by adhesive bonding and/or sealing, said receiving space being separated in a liquid-tight manner from the central opening in said casing.
Claim 3
Dependent Claim
25 words

Claim 4
Dependent Claim
12 words
The plug-type connector of claim 1, wherein the receiving space tapers conically.
Claim 5
Dependent Claim
14 words
The plug-type connector of claim 1, wherein the casing is an injection-molded plastic part.
Claim 6
Dependent Claim
22 words
The plug-type connector of claim 1, wherein the end of the cable sheath closes off the receiving space in substantially liquid-tight fashion.
Claim 7
Dependent Claim
22 words
The plug-type connector of claim 2, wherein an inner wall of the receiving space extends at least partly into the cable sheath.
Claim 8
Dependent Claim
29 words
