## Abstract

An electrical outlet strip is disclosed, the outlet strip comprised of a power source, such as a power cable, and a plurality of socket modules. At least one socket module includes at least one electrical socket electrically interconnected with the power source. Each socket module is mechanically and adjustably engaged with at least one other socket module, whereby the outlet strip is expandable and compressible such that both small power plugs and larger AC adapters may be plugged into the electrical socket of each socket module.

## Claims

### Claim 1

An electrical outlet strip comprising: a power cord having a proximal end and a distal end, the power cord adapted for receiving a power input at the distal end thereof and conducting it to the proximal end thereof; a base module including a housing fixed to the proximal end of the power cord at a distal end thereof, and including a mutual adjustment means, the base module adapted for conducting power from the power cord through the housing; a plurality of socket modules each including a substantially hollow housing, each socket module including the mutual adjustment means, and at least one socket module including at least one electrical socket electrically interconnected to each next adjacent module, each socket for receiving a power plug and providing power thereto; and an end module including a substantially hollow housing having the mutual adjustment means; whereby each socket module or end module may be pulled away from a collapsed position to its next adjacent module to manually select the distance between adjacent electrical sockets by manually adjusting the contiguous mutual adjustment means while maintaining electrical and mechanical connectivity.

### Claim 2 (depends on 1)

The electrical outlet strip of claim 1 wherein each mutual adjustment means is a rigid neck of one socket module slidably retained within an aperture of an adjacent socket module.

### Claim 3 (depends on 2)

The electrical outlet strip of claim 2 wherein each socket module is mechanically prevented from completely disengaging from each adjacent module with a stop means.

### Claim 4 (depends on 2)

The electrical outlet strip of claim 2 wherein the neck portion of each socket module, when in an expanded position with relation to an adjacent module, forms a cable management channel therebetween.

### Claim 5 (depends on 1)

The electrical outlet strip of claim 1 further including a conventional power plug fixed at the distal end of the power cord and electrically connected thereto.

### Claim 6 (depends on 1)

The electrical outlet strip of claim 1 wherein each socket module is electrically connected to each adjacent socket module with a plurality of electrical conductors therein.

### Claim 7 (depends on 6)

The electrical outlet strip of claim 6 wherein at least one of the plurality of electrical conductors is a rigid, conductive bus bar traversing through each socket module.

### Claim 8 (depends on 6)

The electrical outlet strip of claim 6 wherein at least one of the plurality of electrical conductors is a flexible wire.

### Claim 9 (depends on 1)

The electrical outlet strip of claim 1 wherein each socket module is mechanically nestable with each adjacent module when each adjacent module is in a collapsed position therewith.

### Claim 10 (depends on 1)

The electrical outlet strip of claim 1 wherein the base module further includes a power switch for selectively supplying power to the sockets.

### Claim 11 (depends on 10)

The electrical outlet strip of claim 10 further including at least one status light indicator on the base module for indicating the status of the power switch.

### Claim 12 (depends on 1)

The electrical outlet strip of claim 1 further including a surge-protection circuit electrically connected in parallel to each electrical socket.

### Claim 13 (depends on 1)

The electrical outlet strip of claim 1 further including a circuit-breaker electrically connected in series with the power source.
