Abstract
Abstract An optical fiber connector comprises a main body, two ferrules, an adapter, a keying element and a shroud. The main body has a first side wall, a second side wall, a third side wall opposite the first side wall, a fourth side wall opposite the second side wall, two latching arms respectively extending out from the first and third side walls, and two receiving bases attached to the second side wall. Each of the latching arms has at least one latching lug. The two ferrules are received in the receiving bases. The adapter is connected to the fourth side wall of the main body, wherein an optical fiber cable extends out from the adapter and is divided into two parts in an interior of the main body, and the two parts of the optical fiber cable are connected to the ferrules. The shroud movably envelops the receiving bases and has two through holes corresponding to the ferrules and at least one latching hole corresponding to the latching lug. The keying element is rotatably received in a receiving cavity of the shroud and has an indicating means to indicate the present operation type of the optical fiber connector.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
183 words
An optical fiber connector comprising: a main body having a first side wall, a second side wall, a third side wall opposite the first side wall, a fourth side wall opposite the second side wall, two latching arms, each of which has at least one latching lug, respectively extending out from the first and third side walls, and two receiving bases attached to the second side wall; two ferrules received in the receiving bases; an adapter connected to the fourth side wall of the main body, wherein an optical fiber cable extends out from the adapter and is divided into two parts in an interior of the main body, and the two parts of the optical fiber cable are connected to the ferrules; and a shroud movably enveloping the receiving bases of the main body and having two through holes corresponding to the ferrules and at least one latching hole corresponding to the latching lug, whereby the ferrules can stick out from the through holes and the latching lug can engage into the latching hole to fix the shroud to the main body.
Claim 2
Dependent Claim
183 words
An optical fiber connector comprising: a main body having a first side wall, a second side wall, a third side wall opposite the first side wall, a fourth side wall opposite the second side wall, two latching arms, each of which has at least one latching lug, respectively extending out from the first and third side walls, and two receiving bases attached to the second side wall; two ferrules received in the receiving bases; an adapter connected to the fourth side wall of the main body, wherein an optical fiber cable extends out from the adapter and is divided into two parts in an interior of the main body, and the two parts of the optical fiber cable are connected to the ferrules; and a shroud movably enveloping the receiving bases of the main body and having two through holes corresponding to the ferrules and at least one latching hole corresponding to the latching lug, whereby the ferrules can stick out from the through holes and the latching lug can engage into the latching hole to fix the shroud to the main body.
Claim 3
Dependent Claim
26 words
