     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference to  FIGS. 1 to 4 , a pivot plug connector in accordance with the present invention may comply with the high-definition multimedia interface (HDMI) standard and may be connected to a cable ( 90 ) that has two ends and a mounting block ( 91 ) on one end. 
     The pivot plug connector comprises a cable mount ( 10 ), a pivoting member ( 20 ), a rotating member ( 30 ), a plug head ( 40 ) and an internal cable ( 50 ). 
     The cable mount ( 10 ) may consist of two substantially symmetrical casing halves ( 100 ) and has a front end, a rear end, a transverse axis (T) and a cavity ( 11 ) and may further have two pivot brackets ( 12 ), an interval, and two pivot pins ( 13 ). 
     The cavity ( 11 ) is defined in the cable mount ( 10 ) and holds the mounting block ( 91 ) of the cable ( 90 ). 
     With further reference to  FIGS. 9 and 10 , the pivot brackets ( 12 ) are formed on and protrude from the front end. Each pivot bracket ( 12 ) has a first positioning protrusion ( 123 ) formed on and protruding inwardly from the pivot bracket ( 12 ). 
     The interval is defined between the pivot brackets ( 12 ). 
     The pivot pins ( 13 ) are formed respectively on and protrude inward from the pivot brackets ( 12 ) and each pivot pin ( 13 ) has a through hole ( 131 ) defined through the pivot pin ( 13 ) and communicating with the cavity ( 11 ). 
     With reference to  FIG. 5 , the pivoting member ( 20 ) is connected pivotally to the front end of the cable mount ( 10 ) so that the pivoting member ( 20 ) is capable of pivoting around the transverse axis (T). The pivoting member ( 20 ) may consist of two substantially symmetrical casing halves ( 200 ) and has a front end, a rear end, a longitudinal axis (L), a chamber ( 23 ) and may further have a pivot segment ( 21 ) and a supporting segment ( 22 ). 
     The chamber ( 23 ) is defined in the pivoting member ( 20 ) and may have an inner surface and at least one limiting protrusion ( 235 ) formed on the inner surface. 
     The pivot segment ( 21 ) is mounted pivotally on the pivot brackets ( 12 ) of the cable mount ( 10 ), may be mounted in the interval between the pivot brackets ( 12 ) and has two sides, a pivot hole ( 211 ) and two sets of multiple first positioning notches ( 213 ). The pivot hole ( 211 ) is defined transversely through the pivot segment ( 21 ), communicates with the chamber ( 23 ) and the through holes ( 131 ) and has two opposite openings respectively and rotatably accommodating the pivot pins ( 13 ) of the cable mount ( 10 ). The sets of the first positioning notches ( 213 ) are defined respectively in the sides of the pivot segment ( 21 ). Each set engages selectively with the first positioning protrusion ( 123 ) of one pivot bracket ( 12 ) of the cable mount ( 10 ) to position the pivoting member ( 20 ) in a specific angular position relative to the cable mount ( 10 ). 
     With further reference to  FIG. 11 , the supporting segment ( 22 ) is formed on the pivot segment ( 21 ) and has a front end, a rotating element ( 221 ) and multiple second positioning notches ( 223 ). The rotating element ( 221 ) may be a pintle hole defined through the front end of the supporting segment ( 22 ) and communicating with the chamber ( 23 ). The second positioning notches ( 223 ) are defined in the front end of the supporting segment ( 22 ). 
     The rotating member ( 30 ) is connected rotatably to the pivoting member ( 20 ) so that the rotating member ( 30 ) is capable of rotating around the longitudinal axis (L) of the pivoting member ( 20 ). The rotating member ( 30 ) may be mounted rotatably on the front end of the supporting segment ( 22 ) of the pivoting member ( 20 ), may consist of two substantially symmetrical casing halves ( 300 ) and has a front end, a rear end, an internal space ( 31 ), a fastening hole ( 33 ) and may further have a rotating portion ( 32 ). 
     The internal space ( 31 ) is defined in the rotating member ( 30 ). 
     The fastening hole ( 33 ) is defined in the front end of the rotating member ( 30 ) and communicates with the internal space ( 31 ). 
     With further reference to  FIG. 8 , the rotating portion ( 32 ) is formed on the rear end of the rotating member ( 30 ), engages rotatably with the rotating element ( 221 ) of the pivoting member ( 20 ) and may be a pintle. The pintle protrudes from the rear end of the rotating member ( 30 ) and is mounted rotatably in the pintle hole of the pivoting member ( 20 ) and has an aperture ( 321 ), a limiting block ( 325 ) and a second positioning protrusion ( 313 ). The aperture ( 321 ) is defined through the pintle and communicates with the internal space ( 31 ). The limiting block ( 325 ) is formed on and protrudes radially from the pintle and selectively abuts the at least one limiting protrusion ( 235 ) in the chamber ( 23 ) of the pivoting member ( 20 ) to limit the rotating angle of the rotating member ( 30 ) relative to the pivoting member ( 20 ) and prevent wires in the pivot plug connector from over twisting and damage. The second positioning protrusion ( 313 ) is formed on and protrudes radially from the pintle and engages selectively with one of the second positioning notches ( 223 ) of the supporting segment ( 22 ) of the pivoting member ( 20 ) to position the rotating member ( 30 ) at a specific angular position relative to the pivoting member ( 20 ). 
     With further reference to  FIGS. 6 and 7 , the plug head ( 40 ) is mounted in the internal space ( 31 ) of the rotating member ( 30 ), extends out through the fastening hole ( 33 ) and has an insulative housing ( 41 ) and multiple terminals ( 42 ,  43 ) and may further have a shell ( 45 ). 
     The insulative housing ( 41 ) is mounted in the internal space ( 31 ) of the rotating member ( 30 ), extends out through the fastening hole ( 33 ) and has a front end and an engaging hole. The engaging hole is defined in the front end to accommodate a tongue of a corresponding socket connector and has an inner top surface and an inner bottom surface. 
     The terminals ( 42 ,  43 ) are mounted in the engaging hole and may be an upper row of terminals ( 42 ) mounted on the inner top surface and a lower row of terminals ( 43 ) mounted on the inner bottom surface. Each terminal ( 42 ,  43 ) has a rear end. 
     The shell ( 45 ) may be metal and covers the insulative housing ( 41 ). 
     The internal cable ( 50 ) is resilient, is connected to the rear ends of the terminals ( 42 )( 43 ), extends through the internal space ( 31 ) of the rotating member ( 30 ) and the chamber ( 23 ) of the pivoting member ( 20 ) and extends in the cavity ( 11 ) of the cable mount ( 10 ). The internal cable ( 50 ) may have a first sleeve ( 51 ), two second sleeves ( 52 ), a third sleeve ( 53 ) and multiple wires ( 55 ). 
     The first sleeve ( 51 ) is mounted through the aperture ( 321 ) of the rotating member ( 30 ) and the pintle hole of the pivoting member ( 20 ). 
     The second sleeves ( 52 ) are connected to the first sleeve ( 51 ), are mounted in the chamber ( 23 ) of the pivoting member ( 20 ), extend respectively through the openings of the pivot hole ( 211 ) of the pivot segment ( 21 ), extend respectively through the through holes ( 131 ) of the pivot pins ( 13 ) of the cable mount ( 10 ) and extend in the cavity ( 11 ). 
     The third sleeve ( 53 ) is connected to the second sleeves ( 52 ) and is mounted in the cavity ( 11 ) of the cable mount ( 10 ). 
     The wires ( 55 ) are connected respectively to the rear ends of the terminals ( 42 )( 43 ) directly or indirectly, are classified into two groups extending respectively through the second sleeves ( 52 ), all extend in the third sleeve ( 53 ) and are connected to the cable ( 90 ). While  FIG. 5  shows some of the wires ( 55 ), the wires ( 55 ) correspond to the terminals ( 42 )( 43 ). 
     The pivoting member ( 20 ) is connected pivotally to the cable mount ( 30 ) and the rotating member ( 30 ) is connected rotatably to the pivoting member ( 20 ) and allows the pivot plug connector to selectively achieve L-shaped and twisted configurations. Therefore, the pivot plug connector can be adjusted to prevent interference with nearby plug connectors when plugged into a corresponding socket connector.
