  • the base wall 21 bridges the power wire-mounting walls 115, and is formed with two first openings 211 (see Fig. 3) aligned respectively with the retaining grooves 118 in the power wire-mounting walls 115, and a second opening 212 (see Fig. 3) aligned with the opening 119 in the grounding wire-mounting wall 116.
  • the two pairs of limiting ribs 22 extend downwardly from the base wall 21, and are disposed respectively and movably within the slide slots 117 in the sliding rail seat 111.
  • the surrounding wall 23 extends upwardly from an outer periphery of the base wall 21, and defines the accommodating chamber 24.
  • the surrounding wall 23 is rectangular, and has two parallel first walls 231 perpendicular to the longitudinal direction 10, and two parallel second walls 232 parallel to the longitudinal direction 10. Each first wall 231 is formed with two retaining holes 233.
  • the insert rod 25 extends upwardly from the center of the base wall 21, and is disposed in the accommodating chamber 24.
  • the conducting unit 3 includes two spaced-apart conducting plates 31 and a grounding plate 32.
  • Each of the conducting plates 31 is disposed on the base 2, and has a vertical base portion 311 disposed in the accommodating chamber 24, a curved prong-engaging portion 312 extending upwardly from an upper end of the base portion 311, and a curved wire-engaging portion 313 extending from a lower end of the base portion 311 and having a lower end contact portion 314.
  • the prong-engaging portions 312 extend initially from the base portions 311 toward each other, and then away from each other, as shown in Fig. 5.
  • the wire-engaging portions 313 extend respectively into the slide slots 117 through the first openings 211 in the base wall 21 of the base 2.
  • the contact portions 314 extend away from each other, as shown in Fig. 5, and are in electrical contact with the power wires 112, respectively, by extending effectively into the retaining grooves 118.
  • the grounding plate 32 is disposed in the accommodating chamber 24, and includes a vertical base portion 321, a curved prong-engaging portion 322 extending from an upper end of the base portion 321, and a grounding wire-engaging portion 323.
  • the grounding wire-engaging portion 323 extends through the second opening 212 in the base 2 and into the opening 119 in the grounding wire-mounting wall 116, to therefore be in electrical contact with the grounding wire 113.
  • the receptacle seat 4 is mounted rotatably on the insert rod 25, and includes a driving block 41 and a rotary button 42.
  • the driving block 41 is generally elliptical, and has opposite top and bottom surfaces 411, two opposite vertical pushing surfaces 412, two opposite curved non-pushing surfaces 413, and a hole 414 formed through the driving block 41. The distance between the pushing surfaces 412 is greater than that between the non-pushing surfaces 413.
  • the hole 414 has a lower circular hole portion 415 and an upper non-circular hole portion 416.
  • the driving block 41 is disposed between the rotary button 42 and the base 2.
  • the rotary button 42 includes a top wall 421, a surrounding wall 422 extending downwardly from an outer periphery of the top wall 421, and a mounting rod 423 extending downwardly from the center of the top wall 421.
  • the top wall 421 is formed with two power prong-engaging holes 424 and a grounding prong-engaging hole 425.
  • the prong-engaging portion 322 of the grounding plate 32 is disposed in proximity to the grounding prong-engaging hole 425.
  • the mounting rod 423 has a non-circular insert portion 426 engaging fittingly the non-circular hole portion 416 of the hole 414 in the driving block 41 so as to allow for synchronous rotation of the rotary button 42 and the driving block 41, and a bore 427 engaging fittingly an upper end of the insert rod 25 so as to allow for rotation of the rotary button 42 about the insert rod 25.
  • the surrounding wall 422 has a lower end that is formed with an annular flange 428 extending radially and outwardly therefrom.
  • the cover ring 5 has an annular horizontal plate 51 defining a circular hole 511, a surrounding wall 52 extending downwardly from an outer periphery of the horizontal plate 51, and four retaining hooks 53 extending downwardly from the surrounding wall 52.
  • the cover ring 5 is sleeved on the rotary button 42, and abuts against a top surface of the annular flange 428 of the rotary button 42.
  • the retaining hooks 53 engage respectively the retaining holes 233 in the base 2 so as to confine the rotary button 42 between the cover ring 5 and the base 2.
  • the receptacle seat 4 is normally disposed at a conducting position shown in Figs. 4, 5 and 8, where the pressing surfaces 412 of the driving block 41 press respectively against the wire-engaging portions 313 of the conducting plates 31 so as to maintain the positioning of the receptacle seat 4.
  • the power prong-engaging holes 424 in the receptacle seat 4 are aligned respectively with the prong-engaging portions 312 of the conducting plates 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-engaging portions 312 of the conducting plates 31 when the plug is inserted into the power prong-engaging holes 424.
  • the contact portions 314 of the conducting plates 31 extend respectively through the retaining grooves 118 in the power wire-mounting walls 115, and are in electrical contact with the power wires 112. Because of engagement between the conducting plates 31 and the retaining grooves 118, removal of the receptacle unit 12 from the sliding rail unit 11 can be prevented.
  • the rotary button 42 can be operated to rotate the receptacle seat 4 by 90° to a non-conducting position shown in Figs. 6, 7 and 9, where the non-pressing surfaces 413 are aligned respectively with the prong-engaging portions 312 of the conducting plates 31 so as to maintain the positioning of the receptacle seat 4.
