Field of the Invention
[0001] The present invention is related to a power strip having a plurality of electrical
outlets.
Background of the Invention
[0002] Extension cords and power strips are common household objects which are used as a
means to effectively extend the length of the electric cord on an electric appliance
or device. In general, an extension cord consists of a plug for receiving electric
power from a wall socket, an electrical cord and at least one receptacle for providing
electric power to one or more electric devices. In general, an extension cord does
not come with a surge protector circuit and, therefore, it is not very useful for
providing electrical power to a voltage sensitive device such as a computer. A power
strip generally consists of a plug, an electrical cord and one or two rows of electrical
receptacles. Some power strips also come with an on/off switch and a surge protector
circuit. However, the electrical cord on the power strip is an integral part of the
strip and its length is fixed. If the plug, the on/off switch or the surge protector
circuit becomes defective, the entire power strip is usually thrown away. Moreover,
a power strip with a short electrical cord cannot be used to connect to an electric
device which is quite far from a wall socket. A power strip with an electrical cord
with an excessive length, however, is costly and untidy.
[0003] It is advantageous to provide a multiple-outlet power strip wherein the length of
the power cord can be changed.
Summary of the Invention
[0004] It is an objective of the present invention to provide a power strip wherein the
length the electric cord can be changed.
[0005] It is another objective of the present invention to provide a power strip wherein
the outlet section can be replaced or interchanged.
[0006] The above objectives can be achieved by providing a power strip having two separable
sections: a cord section and an outlet section. The cord section consists of a plug,
an electrical connector and an electrical cord electrically connecting the plug and
the connector, the outlet section mainly consists of a plurality of receptacles and
a matching connector to be connected with the connector on the cord section. A number
of options can also be implemented on the outlet section. For example, an outlet section
may further comprise a surge protector device, a timer or an on/off switch. Preferably,
the cord section comes with different cord lengths. With the separable power strips,
the consumer can simply buy a separate cord section and connect it to an existing
outlet section if he or she needs a power strip with a different cord length. When
the cord section becomes defective, one can replace the defective cord section with
another cord section, without buying another outlet section.
[0007] The objectives and the scopes of the present invention will become apparent upon
reading the description of the drawing.
Brief Description of the Drawing
[0008] Fig.1 shows a preferred embodiment of the separable power strip, according to the
present invention.
[0009] Fig.2 shows another embodiment of the present invention.
[0010] Fig.3 shows an embodiment of the outlet section of the separable power strip.
[0011] Fig.4 shows another embodiment of the outlet section.
[0012] Fig.5 shows yet another embodiment of the cutlet section.
Detailed Descripticn of the Invention
[0013] Fig.1 shows a preferred embodiment of separable power strip, according to the present
invention. As shown in Fig.1, the separable power strip consists of a cord section
10 and an outlet section 20. The cord section 10 comprises an electrical cord 12,
a first connector 13, and a plug 11 for receiving electric power from a wall socket
or a similar receptacle. Preferably, the first connector 13 is a female connector.
The outlet section 20 mainly comprises a power strip body 21 to accommodate a plurality
of receptacles 23, and a second connector 22 to be connected with the first connector
13 of a cord section. Preferably, the second connector 22 is a male connector. It
is also preferred that the cord section comes with different cord lengths so that
a consumer can select a cord section with a proper length to connect it to an outlet
section.
[0014] Fig.2 shows another embodiment of the present invention. As shown in Fig.2 the cord
section 30 comprises an electrical cord 33, a connector 34, and a Plug 31 having a
surge protector device 32 so that an electric device that receives electric power
through the connector 34 is protected from unexpected power surge. The connector 34
is compatible with the second connector 22 of the outlet section 20 shown in Fig.1.
In that respect, the cord section 10 and the cord section 30 are interchangable.
[0015] Fig.3 shows an embodiment of the outlet section of the separable power strip. As
shown in Fig.3, the outlet section 40 comprises a power strip body 41 to accommodate
a plurality of receptacles 43, a connector 42 and a time 44 which can be set to turn
on or cut off the Power in one or more receptacles 43 for a preset period at a preset
time. The outlet section may further comprise an on/off switch 46 which can be manually
operated to turn on or cut off the power in all receptacles 43. It is understood that
the connector 42 is compatible with the first connector 13 of the cord section 10
or the connector 34 of the cord section 30 shown in the previous drawing figures.
[0016] Fig.4 shows another embodiment of the outlet section. As shown in Fig.4, the outlet
section 50 comprises a power strip body 51 to accommodate a plurality of receptacles
53, a timer 54, a connector 52 and a surge protector device 55. It is understood that
the connector 52 is compatible with the first connector 13 of the cord section 10
or the connector 34 of the cord section 30. Preferably, an on/off switch 56 is provided
on the outlet section to turn on or trun off the power.
[0017] Fig.5 shows yet another embodiment of the outlet section. As shown in Fig.5, the
outlet section 60 comprises a power strip body 61 to accommodate a plurality of receptacles
63, a connector 62 and a surge protector device 64. It is understood that the connector
62 is compatible with the first connector 13 of the cord section or the connector
34 of the cord section 30. In that respect, the outlet section 60 are interchangeable
with the outlet section 50 shown in Fig.4, the outlet section 40 shown in Fig.3, and
the outlet section 20 shown in Fig.1 and Fig.2. The connector 62 may be designed to
be compatible with the receptacle on a regular extension cord, so that the outlet
section can be used in conjunction with a regular extension cord. But it can also
be designed to be compatible with a PC power cord. It is also understood that one
or more receptacles 63 can be designed as a universal socket, or an electrical socket
compatible with a PC power cord. Moreover, the outlet section may further comprise
a plurality of telephone jacks to accommodate telephone lines and fax machine data
lines, and the telephone jacks may be surge-protected.
