Abstract:
A wire guide for an electronic device has a base being mounted in the electronic device and a protecting tube being pivotally mounted in the base. Wires of the electronic device are mounted through the protecting tube so the wires pivot smoothly to connect the electronic device conveniently to a power supply. Therefore, The wires do not have to be bent or forced so the electronic device is more convenient to use, and safer since the wires and protective tube are not snapped easily.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a wire guide for an electronic device, especially to a wire guide that allows wires of the electronic device to pivot without causing failure to the wires. 
     2. Description of the Prior Arts 
     Electronic devices have a lead and a plug. The plug is electrically connected to a distal end of the lead and is put in a socket to transmit electricity to the electronic device through the lead. 
     With reference to  FIG. 6 , a conventional electronic device ( 40 ), such as an extension cord, has a housing ( 41 ), multiple sockets ( 42 ) and a lead ( 43 ). The housing ( 41 ) has an end and a protecting tube ( 411 ). The protecting tube ( 411 ) is securely mounted on the end of the housing ( 41 ) and has a hole communicating with the housing ( 41 ). The sockets ( 42 ) are separately embedded in the housing ( 41 ) for mounting electrical plugs. The lead ( 43 ) is mounted through and protrudes from the protecting tube ( 411 ) of the housing ( 41 ), is electrically connected to the sockets ( 42 ) and a power supply to provide power to the sockets ( 42 ) and has multiple wires and an insulating cover. The insulating cover is formed around the wires. 
     The protecting tube ( 411 ) prevents the wires of the lead ( 43 ) from being levered out of the end of the housing ( 41 ) or the insulating cover suffering excessive fatigue. However, as the lead ( 43 ) is repeatedly bent and twisted during use, the wires of the lead ( 43 ) may be snapped or the protective tube ( 411 ) removed from the housing ( 41 ), exposing the wires and causing danger of electric shock and fire. Furthermore, extension cords and leads ( 43 ) are frequently hidden behind furniture, along walls or in corners, so removal of the protective tube ( 411 ) may be promoted by persons moving the furniture, forcing the extension cord into a corner or between furniture so crushing the extension cord or protective tube ( 411 ). 
     To overcome the shortcomings, the present invention provides a wire guide for an electronic device to mitigate or obviate the aforementioned problems. 
     SUMMARY OF THE INVENTION 
     The main objective of the present invention is to provide a wire guide for an electronic device. The wire guide has a base being mounted in the electronic device and a protecting tube being pivotally mounted in the base. 
     Wires of the electronic device are mounted through the protecting tube so the wires pivot smoothly to connect the electronic device conveniently to a power supply. Therefore, The wires do not have to be bent or forced so the electronic device is more convenient to use, and safer since the wires and protective tube are not snapped easily. 
     Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to  FIGS. 3 and 4 , an electronic device ( 30 ), such as an extension cord, comprises a housing ( 31 ), multiple sockets ( 32 ) and a lead ( 33 ). The housing ( 31 ) has an upper surface and a mounting recess ( 311 ). The mounting recess ( 311 ) is formed in the upper surface of the housing ( 31 ). The sockets ( 32 ) are separately embedded in the upper surface of the housing ( 31 ) and may be arranged in a line perpendicular to the mounting recess ( 311 ) of the housing ( 31 ). The lead ( 33 ) is mounted in the housing ( 31 ), is electrically connected to the sockets ( 32 ) and has a distal end and multiple wires ( 331 ). The distal end of the lead ( 33 ) is selectively connected electrically to a power supply. 
     With further reference to  FIG. 1 , a wire guide ( 1 ) for the electronic device ( 30 ) in accordance with the present invention is mounted in the mounting recess ( 311 ) of the housing ( 31 ) of the electronic device ( 30 ) and comprises a base ( 10 ) and a protecting tube ( 20 ). 
     With further reference to  FIG. 2 , the base ( 10 ) may be formed from two segments, is securely mounted in the mounting recess ( 311 ) of the housing ( 31 ) of the electronic device ( 30 ), has an upper surface, two opposite pivoting walls ( 14 ), two opposite limiting walls ( 15 ), a tube recess ( 11 ), two pivot holes ( 12 ) and may have two limiting recesses ( 13 ). 
     The tube recess ( 11 ) is formed in the upper surface of the base ( 10 ) and may have a bottom ( 111 ). The bottom ( 111 ) of the tube recess ( 11 ) is semi-cylindrical. 
     The pivot holes ( 12 ) are respectively formed through the opposite pivoting walls ( 14 ) of the base ( 10 ). Each pivot hole ( 12 ) may align with the other pivot hole ( 12 ) of the base ( 10 ). 
     The limiting recesses ( 13 ) are respectively formed in the limiting walls ( 15 ) of the base ( 10 ) and communicate with the tube recess ( 11 ). 
     The protecting tube ( 20 ) may be formed from two segments, may be resilient, is disposed in the tube recess ( 11 ) of the base ( 10 ), is mounted rotatably on the base, and has a shaft ( 21 ) and a cable mount ( 22 ). 
     With further reference to  FIG. 5 , the shaft ( 21 ) is tubular and has a sidewall ( 213 ), two opposite ends ( 211 ) and a guiding channel ( 212 ). The ends ( 211 ) of the shaft ( 21 ) respectively protrude in the pivot holes ( 12 ) of the base ( 10 ) and are mounted rotatably on the opposite pivoting walls ( 14 ) of the base ( 10 ) to allow the protecting tube ( 20 ) to pivot relative to the base ( 10 ). The guiding channel ( 212 ) is formed through the shaft ( 21 ). 
     The cable mount ( 22 ) protrudes transversely from the sidewall ( 213 ) of the shaft ( 21 ), has a sidewall ( 223 ), a through hole ( 221 ) and may have multiple circumferential indentations ( 222 ). The through hole ( 221 ) is formed through the cable mount ( 22 ) and communicates with the guiding channel ( 212 ) of the shaft ( 21 ) to allow the wires ( 331 ) of the lead ( 33 ) of the electronic device ( 30 ) to be mounted through the guiding channel ( 212 ) of the shaft ( 21 ) and the through hole ( 221 ) of the cable mount ( 22 ). The circumferential indentations ( 222 ) are formed around the sidewall ( 223 ) of the cable mount ( 22 ) to allow the cable mount ( 22 ) to be flexed more easily. 
     The wire guide ( 1 ) for the electronic device ( 30 ) as described has the following advantages. As the wires ( 331 ) of the lead ( 33 ) of the electronic device ( 30 ) are mounted through the protecting tube ( 20 ) of the wire guide ( 1 ), the lead ( 33 ) is smoothly pivoted toward different directions to be connected to the power supply and is limited by the limiting recesses ( 13 ) of the base ( 10 ) to prevent over-rotating. Therefore, The wires ( 331 ) of the lead ( 33 ) do not have to be bent repeatedly and wires of each wire ( 334 ) are not snapped easily. Furthermore, the electronic device ( 30 ) may be conveniently placed against a wall, in a corner or the like and the lead ( 33 ) moved for improved ease of installation and use. 
     Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
