Cable sealing and retaining device
The present invention relates to a cable sealing and retaining device capable of sealingly guiding and retaining a cable through an opening of the cable sealing and retaining device. The present invention provides an improved cable sealing and retaining device which allows a simple releasable fixation of a cable to the cable sealing and retaining device while the cable is sealingly guided through an opening provided with the cable sealing and retaining device. The cable sealing and retaining device ( 40;60 ) comprises a sealing part ( 11 ) providing a passageway with an inner seal ( 14 ) through which a cable ( 2 ) is sealingly guidable, and an outer seal ( 15 ) arranged on an outer circumference of the sealing part ( 11 ). The cable sealing and retaining device ( 40; 60 ) comprises a fixation part ( 12 ) for retaining the sealing part ( 11 ) in longitudinal direction of the passageway; and a sleeve portion ( 47; 67 ) forming an opening ( 41; 61 ) for receiving the fixation part ( 12 ) and the sealing part ( 11 ) of the cable sealing and retaining device ( 40; 60 ). The sleeve portion ( 47; 67 ) provides a sealing section ( 42; 62 ) for co-operating with the outer seal ( 15 ) to perform a sealing therebetween. The cable sealing and retaining device ( 40; 60 ) is characterized by the fixation part ( 12 ) which provides fixation means ( 24 ) on its outer circumferential surface to fix the fixation part ( 12 ) to the sleeve portion ( 47; 67 ).
1. A cable sealing and retaining device for an optical fiber cable comprising:
a fiber optic connector terminating the optical fiber cable, the fiber optic connector including a connector body and a release sleeve disposed around the connector body, the connector body having a front end at which an optical ferrule is disposed and a rear end including an attachment feature to which strength members of the optical fiber cable are crimped;
a fixation member disposed on the optical fiber cable to surround the attachment feature, the fixation member being configured to axially secure the cable sealing and retaining device to a port;
a cable seal disposed around the optical fiber cable; and
a second member slidably disposed on the optical fiber cable, the second member including a retention feature that axially secures the second member to the fixation member, the second member being disposed around the cable seal when the second member is axially secured to the fixation member, a front end of the second member having a larger circumference than a rear end of the second member.
2. The cable sealing and retaining device of claim 1 , wherein the second member has a largest circumference that is larger than a largest circumference of the fixation member.
3. The cable sealing and retaining device of claim 1 , wherein the fixation member defines an axial passage open at opposite forward and rearward ends.
4. The cable sealing and retaining device of claim 1 , wherein the second member defines an axial passage open at opposite forward and rearward ends.
5. The cable sealing and retaining device of claim 1 , wherein the fixation member includes a securing member having a forward facing abutment surface and wherein the retention feature of the second member has a rearward facing abutment surface that engages the forward facing abutment surface when the second member is axially secured to the fixation member.
6. The cable sealing and retaining device of claim 5 , wherein the fixation member has two securing members and wherein the retention feature of the second member has two rearward facing abutment surfaces that each engage one of the two securing members when the second member is axially secured to the fixation member.
7. The cable sealing and retaining device of claim 1 , wherein a forward end of the second member is disposed rearwardly of a forward end of the fixation member.
8. The cable sealing and retaining device of claim 1 , wherein the fixation member includes threads to axially secure the cable sealing and retaining device to a port.
9. The cable sealing and retaining device of claim 8 , wherein the threads are external threads.
