Abstract
Abstract The connector pin (2) is protected by a lid (6) which is opened into the sleeve portion (3) when the plug portion (1) is slid in linearly. For this purpose, a sleeve portion is provided with a control path, for example in the form of guide grooves (30), which coordinates with the cover (6). When withdrawing the plug portion (1), the lid (6) is once again closed with the aid of the control path.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
131 words
In an optical fiber connector comprising a plug (1) having at least one connector pin with an optical end surface and a receptacle (3) having at least one sleeve for receiving the connector pin, the plug portion including a shield for protecting the end surface of the connector pin, said shield having a hinge connection with the plug so that it can swing from a closed position covering said end surface to an open position exposing said end surface, the improvement wherein said hinge connection includes an element which is slidably mounted in the plug, and the cover has a guide piece, extending beyond the hinge connection, which engages a protrusion in said receptacle as the plug is inserted, causing the cover to pivot, exposing the pin, and to move rearward.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
19 words
A connector as recited in claim 8, wherein the cover pivot approximately 90° between its open and closed positions.
Claim 4
Dependent Claim
39 words
A connector as recited in claim 1, wherein the plug has an end portion (9) beyond out of which the connector pin protrudes, and the cover, in its closed position, bears against the end surface of the end portion.
Claim 5
Dependent Claim
41 words
A connector as recited in claim 1, wherein the cover has an inner face oriented at an angle with respect to the end surface of the pin, to prevent reflection of light from the inner face back into the optical fiber.
Claim 6
Dependent Claim
19 words
A connector as recited in claim 1, wherein the plug includes a housing having an approximately rectangular cross section.
Claim 7
Dependent Claim
52 words
A connector as recited in claim 1, wherein the sleeve portion is a central component which can be mounted on a housing wall, and the plug portion can be slid into said central component from both sides, and a separate control path is provided for each plug portion in the sleeve portion.
Claim 8
Dependent Claim
17 words
A connector as recited in claim 1, further comprising means for latching the plug in the receptacle.
Claim 9
Dependent Claim
28 words
A connector as recited in claim 1, wherein the plug has a guide slot and the slidably mounted element has a protruding cam which slides in the slot.
Claim 10
Dependent Claim
35 words
A connector as recited in claim 8, wherein the receptacle ha a guide groove and the slidably mounted element has an engagement member which is received in the guide groove when the plug is inserted.
Claim 11
Dependent Claim
33 words
A connector as recited in claim 9, wherein the guide groove is configured so that the cover is retracted into the open position behind the plane of the end surface of the pin.
Claim 12
Dependent Claim
18 words
A connector as recited in claim 8, further comprising a spring biasing the cover towards its closed position.
Claim 13
Dependent Claim
26 words
