Each of theslide slots 117 is disposed between the grounding wire-mounting wall 116 and a respective one of the power wire-mounting walls 115, and is adjacent to the corresponding power wire-mounting wall 115. Each of the power wire-mounting walls 115 defines a mounting space for mounting thecorresponding power wire 112 therein, and is formed with aretaining groove 118 communicated with the mounting space in the corresponding power wire-mounting wall 115 as well as with thecorresponding slide slot 117. The grounding wire-mounting wall 116 also defines a mounting space for mounting thegrounding wire 113 therein, and has a top surface that is formed with anelongated opening 119. Each of thepower wires 112 and thegrounding wire 113 has an end connected electrically to thepower supply unit 13. Thepower supply unit 13 may be configured as an electrical plug. - One of the
receptacle units 12 will be described in the succeeding paragraphs. - The
receptacle unit 12 is disposed above thesliding rail unit 11, and includes abase 2, a conductingunit 3, areceptacle seat 4 and acover ring 5. Thebase 2 is made of a plastic material, and includes abase wall 21, two pairs of limitingrib units 22, a surroundingwall 23, anaccommodating chamber 24 and aninsert rod 25 that has a circular cross section. Thebase wall 21 bridges the power wire-mounting walls 115, and is formed with two first openings 211 (see Fig. 3) aligned respectively with theretaining grooves 118 in the power wire-mounting walls 115, and a second opening 212 (see Fig. 3) aligned with theopening 119 in the grounding wire-mounting wall 116. The two pairs of limitingribs 22 extend downwardly from thebase wall 21, and are disposed respectively and movably within theslide slots 117 in the slidingrail seat 111. The surroundingwall 23 extends upwardly from an outer periphery of thebase wall 21, and defines theaccommodating chamber 24. The surroundingwall 23 is rectangular, and has two parallelfirst walls 231 perpendicular to thelongitudinal direction 10, and two parallelsecond walls 232 parallel to thelongitudinal direction 10. Eachfirst wall 231 is formed with tworetaining holes 233. Theinsert rod 25 extends upwardly from the center of thebase wall 21, and is disposed in theaccommodating chamber 24. - The conducting

Each of theconducting plates 31 is disposed on thebase 2, and has avertical base portion 311 disposed in theaccommodating chamber 24, a curved prong-engaging portion 312 extending upwardly from an upper end of thebase portion 311, and a curved wire-engaging portion 313 extending from a lower end of thebase portion 311 and having a lowerend contact portion 314. The prong-engaging portions 312 extend initially from thebase portions 311 toward each other, and then away from each other, as shown in Fig. 5. The wire-engaging portions 313 extend respectively into theslide slots 117 through thefirst openings 211 in thebase wall 21 of thebase 2. Thecontact portions 314 extend away from each other, as shown in Fig. 5, and are in electrical contact with thepower wires 112, respectively, by extending effectively into theretaining grooves 118. Thegrounding plate 32 is disposed in theaccommodating chamber 24, and includes avertical base portion 321, a curved prong-engaging portion 322 extending from an upper end of thebase portion 321, and a grounding wire-engaging portion 323. The grounding wire-engagingportion 323 extends through the second opening 212 in thebase 2 and into the opening 119 in the grounding wire-mounting wall 116, to therefore be in electrical contact with thegrounding wire 113. - The
receptacle seat 4 is mounted rotatably on theinsert rod 25, and includes adriving block 41 and arotary button 42. Thedriving block 41 is generally elliptical, and has opposite top andbottom surfaces 411, two oppositevertical pushing surfaces 412, two opposite curvednon-pushing surfaces 413, and ahole 414 formed through thedriving block 41. The distance between the pushingsurfaces 412 is greater than that between thenon-pushing surfaces 413. Thehole 414 has a lowercircular hole portion 415 and an uppernon-circular hole portion 416. Thedriving block 41 is disposed between therotary button 42 and thebase 2. Therotary button 42 includes atop wall 421, a surroundingwall 422 extending downwardly from an outer periphery of thetop wall 421, and amounting rod 423 extending downwardly from the center of thetop wall 421. Thetop wall 421 is formed with two power prong-engagingholes 424 and a grounding prong-engaging hole 425. The prong-engaging portion 322 of thegrounding plate 32 is disposed in proximity to the grounding prong-engaging hole 425. Themounting rod 423 has anon-circular insert portion 426 engaging fittingly thenon-circular hole portion 416 of thehole 414 in thedriving block 41 so as to allow for synchronous rotation of therotary button 42 and thedriving block 41, and abore 427 engaging fittingly an upper end of theinsert rod 25 so as to allow for rotation of therotary button 42 about theinsert rod 25. The surroundingwall 422 has a lower end that is formed with anannular flange 428 extending radially and outwardly therefrom. - The
cover ring 5 has an annularhorizontal plate 51 defining acircular hole 511, a surroundingwall 52 extending downwardly from an outer periphery of thehorizontal plate 51, and fourretaining hooks 53 extending downwardly from the surroundingwall 52. Thecover ring 5 is sleeved on therotary button 42, and abuts against a top surface of theannular flange 428 of therotary button 42. Theretaining hooks 53 engage respectively the retainingholes 233 in thebase 2 so as to confine therotary button 42 between thecover ring 5 and thebase 2. - Referring to Figs. 2, 4, 5, and 8, the
receptacle seat 4 is normally disposed at a conducting position shown in Figs. 4, 5 and 8, where thepressing surfaces 412 of thedriving block 41 press respectively against the wire-engagingportions 313 of the conductingplates 31 so as to maintain the positioning of thereceptacle seat 4. In the conducting position, the power prong-engagingholes 424 in thereceptacle seat 4 are aligned respectively with the prong-engagingportions 312 of the conductingplates 3, as shown in Fig. 8, so as to allow for electrical contact of two power prongs of a plug (not shown) with the prong-engagingportions 312 of the conductingplates 31 when the plug is inserted into the power prong-engaging holes 424. Also in the conducting position, thecontact portions 314 of the conductingplates 31 extend respectively through theretaining grooves 118 in the power wire-mounting walls 115, and are in electrical contact with thepower wires 112. Because of engagement between the conductingplates 31 and theretaining grooves 118, removal of thereceptacle unit 12 from thesliding rail unit 11 can be prevented. - The
rotary button 42 can be operated to rotate thereceptacle seat 4 by 90° to a non-conducting position shown in Figs. 6, 7 and 9, where thenon-pressing surfaces 413 are aligned respectively with the prong-engaging portions 312 of the conductingplates 31 so as to maintain the positioning of thereceptacle seat 4. In the non-conducting position, each of the power prong-engaging holes 424 in thereceptacle seat 4 is deflected from the prong-engagingportion 312 of thecorresponding conducting plate 31, as shown in Fig. 9. As a result, when the plug is inserted into thereceptacle unit 12, because one of the power prongs of the plug is blocked by one of theconducting plates 31, the power prongs of the plug cannot be inserted completely into the power prong-engaging holes 424. This prevents electrical contact between the plug and both the conductingplates 31. Also in the non-conducting position, thecontact portions 314 of the conductingplates 31 are removed from the retaininggrooves 118 in the power wire-mountingwalls 115 and, therefore, as well as thepower wires 112. This allows for removal of thereceptacle unit 12 from the slidingrail unit 11.
