## Abstract

The present invention relates to a safety female adapter device for fiber optic connections, configured to house a male optical connector, characterized in that it includes controlled release locking means configured to constrain a longitudinal sliding of the male connector with respect to the female adapter device, when the connector is inserted in the adapter device to establish the optical connection, and release the longitudinal sliding of the connector with respect to the adapter device, during the insertion or disconnection of the male connector in/from the female adapter device.

## Claims

### Claim 1

A safety female adapter device for fiber optic connections, configured to house a SC male optical connector,
said safety female adapter device comprising a substantially box-shaped casing having a longitudinal reference slot on a wall of said casing at an insertion portion of the male connector, said slot being dimensioned to allow a reference protuberance of the SC male connector sliding inside the slot and guiding a coaxial insertion of the SC male connector into the female adapter device,
said safety female adapter device comprising a controlled-release lock configured to constrain a longitudinal sliding of the male connector with respect to the safety female adapter device, when the connector is inserted into the safety female adapter device to establish the optical connection, and release the longitudinal sliding of the connector with respect to the safety female adapter device, during the insertion or removal of the male connector into/from the safety female adapter device, wherein said lock comprises a locking lever, wherein said locking lever is comprised between two substantially longitudinal notches running along said slot, said locking lever having a closing stop at a terminal end of said slot, said terminal end facing towards a front opening of said casing, said closing stop being able to be moved from a lowered position to a raised position to allow the insertion of the reference protuberance of the male connector into said slot and from a raised position to a lowered position to provide a blockage of an exit of the male connector from said safety female adapter device.

### Claim 2 (depends on 1)

The safety female adapter device according to claim 1, wherein said closing stop has a tilted guide portion.

### Claim 3 (depends on 2)

The safety female adapter device according to claim 2, wherein said locking lever has two lateral rails.

### Claim 4 (depends on 1)

A double female adapter device configured to house an optical connection between a first and a second optic fiber connector inserted or insertable into said double female adapter device, comprising at least one safety female adapter device according to claim 1.

### Claim 5 (depends on 1)

A safety adapter system comprising a safety female adapter device according to claim 1 and a closing plug configured to be housed into said safety female adapter device as an alternative to the optical connector.

### Claim 6 (depends on 5)

The safety adapter system according to claim 5, wherein said closing plug comprises a reference protuberance dimensioned to be slidable into a slot of said safety female adapter device, said sliding being constrainable via an interaction of the protuberance with said lock.

### Claim 7 (depends on 1)

An optical connection system comprising an active or passive optical device and a safety female adapter device according to claim 1.
