## Background
BACKGROUND
1. Technical Field
The present disclosure relates to power strips and, more particularly, to a power strip including at least one socket module removably attached to a housing thereof.
2. Description of Related Art
The popularity of electrical power strips has grown in pace with the increased use of personal computer equipment, electrical appliances, and the like. However, due to the different positions equipment may be placed in a location, the shared use of one power strip becomes difficult. Therefore, there is a need to provide a power strip that includes an extendable socket module to solve the abovementioned problem.

DETAILED DESCRIPTION
Referring to FIGS. 1-3, in an exemplary embodiment, a power strip 10 includes a housing 100 and a first power cord 200. The housing 100 is substantially rectangular and includes a front surface 110. The cord 200 extends from the front surface 110 and is used to receive an input of electricity from a power source (not shown). The cord 200 includes a plug 210 that may be plugged into a wall outlet (not shown).
The housing 100 further includes a plurality of socket modules 120a and at least one socket module 120b arranged in an upper surface of the housing 100 for receiving electrical plugs (not shown). In the exemplary embodiment, each of the socket modules 120a and the socket module 120b includes three socket holes. However, the number of the socket holes of each socket module is not limited and may be two or more than three according to need.
In the exemplary embodiment, the socket modules 120a are fixed to the housing 100 and the socket module 120b is removably attached to the housing 100. Specifically, a hollow cavity 130 is formed in the housing 100 and the socket module 120b is received in the hollow cavity 130.
In the exemplary embodiment, the socket module 120b includes a top portion 121, a bottom portion 122, and a reel portion 123 extended therebetween. The three socket holes of the socket module 120b are formed in the top surface of the top portion 121.
The top portion 121 is hollow and includes connectors (not shown) for engaging with electrical plugs (not shown). A second power cord 124 is connected to the connectors and is guided out through an opening (not labeled) formed in the bottom surface of the top portion 121. The second power cord 124 is connected to the first power cord 200.
The reel portion 123 is a round protrusion protruded from the bottom portion 122. The second power cord 124 is wound on the reel portion 123. The bottom portion 122 is a rectangular plate.
In the exemplary embodiment, four magnetic members 300 are disposed on the bottom surface bounding the cavity 130 and four magnetic members 400 are attached to the bottom surface of the bottom portion 122. The four magnetic members 400 are placed on the corners of the bottom portion 122. The magnetic members 300 and 400 are disposed so they attract one another, thereby enabling the socket module 120b to be removably attached to the housing 100.
In another embodiment, four magnetic members 300 are disposed on the bottom surface of the cavity 130 and the bottom portion 122 is made of metal material. The magnetic members 300 are disposed to attract the bottom portion 122, thereby enabling the socket module 120b to be removably attached to the housing 100.
In the exemplary embodiment, two recessed portions 140 are formed in the upper surface of the housing 100 and communicate with the cavity 130. The two recessed portions 140 enable a user's fingers to grasp two side walls of the top portion 121 to draw the socket module 120b out of the cavity 130.
When in use, a user can remove the socket module 120b from the housing 100 and rotate the socket module 120b to release the second power cord 124 wound on the reel portion 123. With the second power cord 124 released, the socket module 120b can then be placed in a position away from the housing 100, thereby enabling more flexibility in the placement of equipment (not shown) releative to placement of the power strip 10.
While various embodiments have been described and illustrated, the disclosure is not to be constructed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
