Technical field of the invention:

The invention relates to an Electrical Power Extension Cord with Multi-Connector for joining two electric cables together or multi appliances or machines in houses, factories, and in any buildings and in which the cables each include one, two, or more conductors.

Background of the invention:

Connecting devices by electric cable are well known and have been in wide spread use for a number of years.

For examples, a Us Patent Application of Daoud 13/221959 discloses an electrical connector for joining two cables each of which contains one or more separate conductors together to complete an electrical connection. The electrical connector include a longitudinally extending triangle shaped inner body having a central core, two, or three outwardly extending walls, two or three outer body members with one of the body members disposed on an outer end of each of the wails, and wherein the number of walls and body members are equal to at least the number of conductors in a. cable being joined together. The connector also includes an outer tubular housing extending around the triangular inner body member and a-shaped outer members. In addition, the connector includes three pair of clamps at each end for fixing and positioning the conductors iii place and in contact with two longitudinally extending conductors, The main problems of this invention are the heat can affect the connector and the fixing of wires inside the connector isn't perfectly.

The EP200 1090 (A2) field on 2008-12-10, the invention relates to a multiple extension cord for communications and power cables formed by at least one electrical cable, one telephone cable and one television antenna cable, an insulating and flexible outer tubular body housing them therein, leaving the fixed end and the free end of each of the cables exposed, and a casing with electrical, telephone and television antenna outlets to which the fixed ends of the cables are connected, the free ends of said cables being couplable to electrical, telephone, and television antenna outlets arranged in an enclosure.

Detailed description of the invention:

The present invention contemplates an electrical power extension cord with multi-connector for joining series of two electric cables together and also multiple devices, appliances or machines in houses, factories, or in any buildings in the same time and in which the cables each include one, two, or more conductors. The power extension cord has a main plug connected with multi-connectors by main electric cord to connect multi series of two cables together or connect multiple appliances.

According to fig. 1, the power extension cord has a main plug (1) which is connected with multi-connectors (2) by main electric cord (3) to connect multi series of two cables together or connect multiple appliances. The main plug (1) has two or thee terminal pins (6), circuit breaker (5) for safety and for protection, blade cutter (4) to cut the cover of the electric cable, ampere meter (7) to measure the flow current shown in fig. 2 and USB sockets (8) for cellular phone charger (shown in fig. 3). Also, for more protection of the plug there is a fuse (9) (shown in fig. 8).

The multiple electric connectors (2) as in first embodiment of the invention (shown in fig. 4) for joining two electric cables together, consist of lower connector base (24),font and back covers (23) which are opened and closed by screw (25). Also, the connector (2) ha.s three longitudinal cylindrical tubular channels (22) extended through the connector. Through the channels, the insulated conductors are mounted. The channels are divided symmetrically, half of them are housed in the lower base (24) and the other half is mounted in the covers (23). There is a conductive plate as copper (28) housed in the lower half of the channels base (24) to connect the electric wire together. Each channel is colored by different color to reduce the user's time and help him to connect conductors easily.

The two movable covers (23) in the upper of the connector (2) are separated by middle plastic part (29). All channels extended under the plastic part (29) in both sides. There is a clamping member slot (2i) of electrical cables is made of waterproof sponge rubber to clamp, hold and fix the electric cable inside the connector.

In the upper part of each channel (22) housed in covers (23), There is a.

plastic wire pillars pusher (26) to push and press on the insulated conductors inside the lower base part of channels so the a sharp abrasive (27) (made from copper) cut the insulated conductor cover and contact the inner core copper of the insulated conductor. So the current flow inside the cable.

The power extension cord (3) has two, three or more heavy insulated conductors (32) which are extended longitudinal the extension cord (32) as in fig. 5. The main insulated conductors (32) are used to connect multiple connectors (2) by contact the electric passing conductive bridge (31) with the copper channel plates (28). The thickness of the heavy duty insulated conductors (32) is very big to bear the overload.

The blade cutter tool (8) works as clamping tools (shown in fig. 6) to cut the electric wire cover and the user just put the cable in channels (22) and rotate the cable to cut the cover of it and so he can separate the three insulated conductors of the cable and mount them in different channel (22). The cutter tool (8) has a blade (82) and the blade is pressed by a cutter button (81).

The plug (1) according to fig. 7 consists of lower base (12) wherein the heavy duty insulated conductors terminals (ii) are housed in three channels.

The end of the three terminals (1) are housed in three pipes (17) made of conductive material as copper. The three copper pipes has holes (18) wherein the three plastic pillars pusher (16) are go through and push, and clamp the wires inside the pipes (17). So, the sharp abrasive (19) (made from copper shown in fig. 10) cut the insulated conductors terminals (II) cover and contact the inner core copper of the insulated conductor terminals.

The plug cover (13) is opened and closed by the screw (15) where it is housed in the screw slot (14).

in another embodiment of the invention, the electncal power extension cord with multi-connector is used for joining series of any devices as in fig. it.

The user can connect any devices with the power extension cord (3) by using the power socket connector (2'). The power socket connector (2') has base socket (2a) which is divided by middle plastic part (2d). Each side of the base has three pin sockets (2b) to put the plug of any devices in it. The cable of any device is fixed and clamping by cable clamp (2c). so the extension power cable extend to have many series of power socket connectors.

In another embodiment of the invention, the electrical power extension cord with multi-connector is used for joining series of two electric cables together or series of any devices at the same time. The electrical connector either 2 or 2' can connect both electric cables and a plug of a device in the same time by dividing the connector to have one side for joining cables and the other side for connect the plug of any device (not shown in figures).

In another embodiment of the invention, the plug 1 ma.y have two pins and the extension cord have also two or more insulated conductors. Also, the extension power cord is suitable for all types of electrical cable with different sizes. And also it is suitable to connect or join all cables which contains more than three separate insulated conductors. Also, the connector has different shapes.
