Abstract
Abstract A multiple channel fiber optic connector (44) carries a plurality of fiber optic socket termini (58, 60, 62, 64), each of which includes an alignment sleeve (42) mounted on a forward end. In order to facilitate installation of the alignment sleeves and removal of the sleeves for cleaning of the sleeves (42) and the end (35) of the optical fiber (34) of each socket terminus, the alignment sleeves (42) for each terminus of the connector (44) are all securely mounted in an alignment sleeve carrier (46). The carrier itself is detachably connected to the connector 44 and, when so connected, positions each alignment sleeve on its respective fiber optic terminus. A simply and easily operated latch mechanism (100, 82) latches the carrier to the connector body to hold all of the alignment sleeves in place and is readily operated by a plunger 150, without any type of tool, to enable the carrier together with all of its alignment sleeves to be removed from the connector body and expose the ends (35) of fibers for cleaning.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
Apparatus for detachably connecting a first part to a second part comprising: a post fixed to said first part and extending forwardly therefrom, said post having a head section having a first external diameter, a latch section of decreased external diameter and an inclined post shoulder between said sections, a resilient sleeve axially slidable on said post at said latch section having an outwardly flared end positioned at said shoulder, said second part having a bore receiving said post, said bore having an inner section of a first internal diameter and a latch section of decreased internal diameter, said bore latch section being positioned at said post latch section and having an inclined bore shoulder between said bore inner section and said bore latch section, said sleeve flared end being captured between said post shoulder and said bore shoulder, and means for axially shifting said sleeve relative to said shoulders.
Claim 2
Dependent Claim
150 words
Apparatus for detachably connecting a first part to a second part comprising: a post fixed to said first part and extending forwardly therefrom, said post having a head section having a first external diameter, a latch section of decreased external diameter and an inclined post shoulder between said sections, a resilient sleeve axially slidable on said post at said latch section having an outwardly flared end positioned at said shoulder, said second part having a bore receiving said post, said bore having an inner section of a first internal diameter and a latch section of decreased internal diameter, said bore latch section being positioned at said post latch section and having an inclined bore shoulder between said bore inner section and said bore latch section, said sleeve flared end being captured between said post shoulder and said bore shoulder, and means for axially shifting said sleeve relative to said shoulders.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 wherein said post head section has an external diameter slightly less than the internal diameter of said bore latch section.
Claim 4
Dependent Claim
19 words
The apparatus of claim 1 wherein said means for shifting comprises a plunger slidably mounted in said second part.
Claim 5
Dependent Claim
19 words
The apparatus of claim 3 wherein said plunger includes a plunger actuating projection extending outwardly of said second part.
Claim 6
Dependent Claim
22 words
The apparatus of claim 1 including spring means in said first part for urging said second part away from said first part.
Claim 7
Dependent Claim
36 words
The apparatus of claim 1 wherein said resilient sleeve is longitudinally split and includes a plurality of longitudinal slots extending from said flared end and dividing said flared end into a plurality of resilient spring fingers.
Claim 8
Dependent Claim
85 words
The apparatus of claim 1 wherein said sleeve is axially shiftable between a latched position in which said sleeve flared end is captured between and in contact with said post shoulder and said bore shoulder, and an unlatched position in which said sleeve flared end is spaced from and positioned behind said post shoulder and is positioned radially inwardly of said decreased internal diameter latch section of said bore, whereby in said unlatched position said post shoulder may be axially shifted post said bore shoulder.
