## Abstract

A cleaning module adapted to clean a socket or a pin of a ferrule includes a tip assembly comprising a tip, the tip adapted to receive a cleaning media, a retractable alignment sleeve spring-mounted on a retractable alignment sleeve spring, wherein the sleeve retracts when a flange of an opening of the tip assembly presses against a surface of the ferrule, and wherein the retractable alignment sleeve is sized to surround the pin, and a main spring that extends the tip assembly, wherein the retractable alignment sleeve spring has both a spring constant and total compressive force that are lower than that of the main spring.

## Claims

### Claim 1

A cleaning module adapted to clean a socket or a pin of a ferrule, comprising:
a housing;
a tip assembly extending from the housing, the tip assembly comprising a tip adapted to receive a cleaning media;
a retractable alignment sleeve having a flange at an end thereof, the alignment sleeve adapted to move along the tip assembly during use between a first position adjacent to the tip and a second position displaced from the tip in a direction toward the housing, wherein the sleeve retracts when the flange presses against a surface of the ferrule and further when the sleeve is sized to surround the pin;
a sleeve spring having a first end portion engaged with a portion of the housing and a second end portion engaged with the flange of the alignment sleeve; and the tip assembly being mounted to a block movably secured within a portion of the housing,
a main spring within the housing and engaged with an end portion of the block that allows the tip assembly to move relative to the housing during use, and
further wherein the sleeve spring has both a spring constant and total compressive force that are lower than that of the main spring.

### Claim 2 (depends on 1)

The cleaning module of claim 1, wherein the cleaning module comprises a guide slot to continually provide an unused portion of cleaning media to the tip that contacts a socket or the pin, and wherein the cleaning media is continually carried away after use.

### Claim 3 (depends on 1)

The cleaning module of claim 1, wherein the tip is a rectangular tip adapted for cleaning optical fiber end faces of MT connectors.

### Claim 4 (depends on 1)

The cleaning module of claim 1, wherein the cleaning media is selected from one or more of a fabric, a thread and a yarn.

### Claim 5 (depends on 4)

The cleaning module of claim 4, wherein the fabric is a polyester or nylon fabric.

### Claim 6 (depends on 4)

The cleaning module of claim 4, wherein the fabric is a felt material.

### Claim 7 (depends on 4)

The cleaning module of claim 4, wherein the cleaning media is formed of a lint-free material.
