Abstract
Abstract A fiber optic connector plug body (1) receives a ferrule (2) therewithin. The plug body (1) receives an internal body (5) in a snap fit to retain the ferrule (2) within the plug body (1). Two inwardly biased latch members (14) on the plug body (1) are received within a circumferential groove on the internal body. The resulting assembly is resistant to disassembly upon application of tensile and lateral forces to the internal body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
A preassembled fiber optic connector comprising: (a) a hollow plug body (1) having at least two inwardly biased latch members (14), a mating end (11), and a nonmating end (10), (b) a fiber alignment ferrule (2) within said plug body, (c) an axial biasing element (4) within said plug body urging said ferrule toward said mating end, and (d) an internal body (5) rearward of said axial biasing element and said ferrule, said internal body captivating said ferrule and said axial biasing element within said plug body, said internal body having a recess (51) bounded by walls (52), wherein said recess receives said latch members and said walls of said recess interfere with said latch members to retain said internal body within said plug body.
Claim 2
Dependent Claim
125 words
A preassembled fiber optic connector comprising: (a) a hollow plug body (1) having at least two inwardly biased latch members (14), a mating end (11), and a nonmating end (10), (b) a fiber alignment ferrule (2) within said plug body, (c) an axial biasing element (4) within said plug body urging said ferrule toward said mating end, and (d) an internal body (5) rearward of said axial biasing element and said ferrule, said internal body captivating said ferrule and said axial biasing element within said plug body, said internal body having a recess (51) bounded by walls (52), wherein said recess receives said latch members and said walls of said recess interfere with said latch members to retain said internal body within said plug body.
Claim 3
Dependent Claim
46 words
A fiber optic connector as recited in claim 1 wherein, said internal body has a forward body section (53) contained by said plug body forward of said latch members to resist deflection of said latch members in response to lateral forces applied to said internal body.
Claim 4
Dependent Claim
22 words
A fiber optic connector as recited in claim 1 wherein, said latch members have an inner diameter that follows a cylindrical contour.
Claim 5
Dependent Claim
20 words
A fiber optic connector as recited in claim 1 wherein, said latch members and said plug body are integrally molded.
Claim 6
Dependent Claim
20 words
A fiber optic connector as recited in claim 1 wherein, said recess is a circumferential groove in said internal body.
Claim 7
Dependent Claim
137 words
A terminated fiber optic connector comprising: (a) a hollow plug body having at least two inwardly biased latch members, a mating end, and a nonmating end, (b) a fiber alignment ferrule within said plug body, said ferrule having a central fiber passage therethrough, (c) an optical fiber retained within said fiber passage (d) an axial biasing element within said plug body urging said ferrule toward said mating end, and (e) an internal body rearward of said axial biasing element and said ferrule, said internal body providing a reaction face for said axial biasing element as it urges said ferrule toward said mating end, said internal body having a recess bounded by walls that receives said latch members wherein said walls of said recess interfere with said latch members to retain said internal body within said plug body.
Claim 8
Dependent Claim
137 words
A terminated fiber optic connector comprising: (a) a hollow plug body having at least two inwardly biased latch members, a mating end, and a nonmating end, (b) a fiber alignment ferrule within said plug body, said ferrule having a central fiber passage therethrough, (c) an optical fiber retained within said fiber passage (d) an axial biasing element within said plug body urging said ferrule toward said mating end, and (e) an internal body rearward of said axial biasing element and said ferrule, said internal body providing a reaction face for said axial biasing element as it urges said ferrule toward said mating end, said internal body having a recess bounded by walls that receives said latch members wherein said walls of said recess interfere with said latch members to retain said internal body within said plug body.
