Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to scent releasing devices and more specifically, to a lamp socket and cable bracket assembly, which is equipped with a flat cable bracket configured to hold electrical wires in a smoothly curved manner against stretching and to dissipate heat radiated by the lamp bulb, avoiding electrical wire damage. 
       DESCRIPTION OF THE RELATED ART 
       [0002]    An electrical wire fixation structure for lamp socket must pass a tensile strength test, avoiding disconnection from the lamp socket upon an external force. In U.S. Ser. Nos. 12/614,189; 12/626,979, a plastic bracket is fastened to the holder base of the lamp socket for holding electrical wires. The plastic bracket comprises a transverse extension lug, a wire hole cut through the transverse extension lug and two wire notches at two sides relative to the transverse extension lug. The electric wires are inserted through the wire hole on the transverse extension lug and turned backwardly apart and then respectively attached to the wire notches for electrically connecting two metal terminals in the holder base to an external power source. After installation, the electrical wires are curved in a large angle. As the electrical wires are heavily curved, the molecules of the insulation of the electrical wires at the curved corners may be damaged when the electrical wires are stretched by an external force. Further, the insulation of the electrical wires at the curved corners will deteriorate in mechanical strength under the effect of the heat energy released by the lamp bulb. 
       SUMMARY OF THE INVENTION 
       [0003]    The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a lamp socket and cable bracket assembly, which holds electrical wires in a smoothly curved manner against stretching and quickly dissipates heat radiated by the lamp bulb, avoiding electrical wire damage. 
         [0004]    To achieve this and other objects of the present invention, a lamp socket and cable bracket assembly comprises a lamp socket, electrical wires electrically connected to respective electrodes in the lamp socket for connection to power source, and a high tensile strength cable bracket for securing the electrical wires. The high tensile strength cable bracket is a plate member comprising a mounting lug fixedly connected to the lamp socket, a planar panel, a sloping panel obliquely connected between the mounting lug and the planar panel, a first cable-retaining notch and a second cable-retaining notch respectively and symmetrically located on two opposite lateral sides of the sloping panel, and a third cable-retaining notch and a fourth cable-retaining notch respectively and symmetrically located on two opposite lateral sides of the planar panel. 
         [0005]    Further, the first, second, third and fourth cable-retaining notches each define a mouth. The mouth has a width relatively shorter than the internal width of the respective cable-retaining notch. 
         [0006]    Further, the first electrical wire is inserted from the bottom side of the sloping panel through the first cable-retaining notch toward the top side of the planar panel, and then extended downwardly through the third cable-retaining notch to the bottom side of the planar panel and then turned forwardly out of the cable bracket to the power source. Further, the second electrical wire is inserted from the bottom side of the sloping panel through the second cable-retaining notch toward the top side of the planar panel, and then extended downwardly through the fourth cable-retaining notch to the bottom side of the planar panel and then turned forwardly out of the high tensile strength cable bracket to the power source. 
         [0007]    The lamp socket and cable bracket assembly further comprises a lamp bulb installed in the lamp socket and electrically connected to the electrodes for giving off light and heat energy, and an aroma-diffusion lampshade fastened to the lamp socket around the lamp bulb and configured to hold an aromatic substance in a recessed top side thereof for heating into vapor by the heat energy released by the lamp bulb. Further, the aroma-diffusion lampshade has a cable hole for the passing of the first electrical wire and the second electrical wire. 
         [0008]    Further, the cable bracket can transfer heat energy for quick dissipation of heat, maintaining the mechanical strength of the electrical wires.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0015]    Referring to  FIGS. 1-3 , a lamp socket and cable bracket assembly in accordance with the present invention is shown comprising a lamp socket  2  and a high tensile strength cable bracket  3 . 
         [0016]    The high tensile strength cable bracket  3  comprises a mounting lug  31  fixedly connected to the lamp socket  2 , a planar panel  35 , a sloping panel  33  obliquely connected between the mounting lug  31  and the planar panel  35 , a first cable-retaining notch  331  and a second cable-retaining notch  333  respectively and symmetrically located on two opposite lateral sides of the sloping panel  33 , and a third cable-retaining notch  351  and a fourth cable-retaining notch  353  respectively and symmetrically located on two opposite lateral sides of the planar panel  35 . 
         [0017]    Each of the cable-retaining notches  331 ; 333 ; 531 ; 533  defines a mouth C. The mouth C has a width relatively shorter than the internal width of the respective cable-retaining notch  331 ; 333 ; 531 ; 533 , facilitating quick positioning of electrical wires in the cable-retaining notches  331 ; 333 ; 531 ; 533 . Further, through holes can be formed in the sloping panel  33  and the planar panel  35  instead of the cable-retaining notches  331 ; 333 ; 531 ; 533  for securing electrical wires. 
         [0018]    Referring to  FIG. 4 , the lamp socket and cable bracket assembly further comprises a first electrical wire  4  and a second electrical wire  5 . The first electrical wire  4  and the second electrical wire  5  are respectively electrically connected to the electrodes E of the lamp socket  2  at right angles. Further, the first electrical wire  4  is inserted from the bottom side of the sloping panel  33  through the first cable-retaining notch  331  toward the top side of the planar panel  35  and then extended downwardly through the third cable-retaining notch  351  to the bottom side of the planar panel  35  and then turned forwardly out of the cable bracket  3  to the power source. The second electrical wire  5  is inserted from the bottom side of the sloping panel  33  through the second cable-retaining notch  333  toward the top side of the planar panel  35  and then extended downwardly through the fourth cable-retaining notch  353  to the bottom side of the planar panel  35  and then turned forwardly out of the high tensile strength cable bracket  3  to the power source. 
         [0019]    Thus, the first electrical cable  4  and the second electrical cable  5  are respectively secured to the first and third cable-retaining notches  331 ; 351  of the high tensile strength cable bracket  3  and the second and fourth cable-retaining notches  333 ; 353  of the high tensile strength cable bracket  3 , avoiding a large angle curving of the electrical wires  4 ; 5 . When the electrical wires  4 ; 5  are stretched by an external force, the high tensile strength cable bracket  3  transfer the stretching force to the lamp socket  2 , avoiding disconnection of the electrical wires  4 ; 5  from the electrodes E of the lamp socket  2 . 
         [0020]    Referring to  FIGS. 3 and 4  again, the electrodes E are arranged in one side of the lamp socket  2 . Preferably, the electrodes E are arranged in the lamp socket  2  in a parallel manner so that the respective ends of the first and second electrical wires  4 ; 5  can be conveniently and straightly connected to the electrodes E in a parallel manner without bending. 
         [0021]    Referring to  FIG. 4  again, a first binding strap  6  is fastened to the high tensile strength cable bracket  3  to hold down the first electrical cable  4  in the first cable-retaining notch  331  of the high tensile strength cable bracket  3  and the second electrical cable  5  in the third cable-retaining notch  333 . 
         [0022]    Further, a second binding strap  7  is fastened to the high tensile strength cable bracket  3  to hold down the first electrical cable  4  in the second cable-retaining notch  351  of the high tensile strength cable bracket  3  and the second electrical cable  5  in the fourth cable-retaining notch  353 . 
         [0023]    Further, the high tensile strength cable bracket  3  is prepared by a thermal conductive plate member. When viewed from one side, the high tensile strength cable bracket  3  shows a substantially Z-shaped configuration for supporting the first electrical wire  4  and the second electrical wire  5  in a smoothly curved manner, avoiding internal conductor damage. 
         [0024]    Referring to  FIGS. 5 and 6 , the lamp socket  2  holds an aroma-diffusing lampshade  8  and a lamp bulb  9 . The lamp bulb  9  is installed in the lamp socket  2  for giving off heat and light energy. The aroma-diffusing lampshade  8  is fastened to the lamp socket  2  around the lamp bulb  9 , having a cable hole  81  for the passing of the first electrical wire  4  and the second electrical wire  5 . Further, the aroma-diffusing lampshade  8  is prepared by a light transmissive material with high mechanical strength. Further, the aroma-diffusing lampshade  8  configured to hold an aromatic substance (such as essential oil, fragrant wax or the like) in a recessed top side thereof. When the lamp bulb  9  is electrically connected to give off light and heat energy, the aromatic substance in the recessed top side of the aroma-diffusing lampshade  8  will be heated into vapor. Thus, the invention is practical for home use as well as for SPA and beauty shop applications.
