Description:
PRIOR ART OF THE INVENTION 
     Due to that the LED (light emitting diode) has the characteristics of lower power consumption, low generating heat and long service life, the former Christmas lamps or other decoration lamps using traditional lamps are gradually replaced by LEDs. However, the LED has the electrical directivity; it will not be lightened once the current direction is reversed. Therefore, it will cause the flickering while 10V or 220V AC (alternative current) are used and it also wastes the electrical energy. Presently, a socket setting additionally with the rectification diode is emerged, the problems of unstable current and voltage are solved through it such that the luminance of lamps in the LED lamp string can be stabilized and the service life can be prolonged. However, two rectification diodes need to be set additionally in the socket, and the ordinary design is using the welding method to weld one pin of the rectification diodes separately with the left and right terminals connect-setting with electrical wires and connect-weld the other pin of the rectification diodes together. However, it not only needs to be processed with care by man while proceeding the welding work, but also the narrow assembling space in the socket causes easily the inconvenience of welding process. It relatively will cause the increase in the manufacturing cost. It is not really ideal and thus waits to be improved.

The top of said base  10  is hollow, and the left, right compartment  102 ,  103  are formed by a central partition plate  101 . The left, right copper plug pins  11 ,  12  are laid in the front end of the left, right compartment  102 ,  103 , and the left, right copper seats  13 ,  14  are laid in the rear end. And, a fuse  20  is laid in between left, right copper plug pins  11 ,  12  and left, right copper seats  13 ,  14  to form a conduction. The front plugging socket can be sleeved in with a outer shell (not sown in figures) to form a complete front plugging plug. The feature of present invention is that a housing hole&#39;s seat  104  is set on the base  10  face in the end of central partition plate  101 . It is further distribute-set with left, right rectification diodes  30 ,  31  and a conductive connector  40  with its top end set with outward-bent conductive connecting plate  41  having a through hole  42  in the center.

Its main composing elements and setup method is the same as the front plugging socket with two conductive wires. The different point is there is set with a third electrical wire  52 . And, its assembling method is extremely simple. It just requires to insert the copper wire portion in the front end of electrical wire  52  directly into the through hole  42  of conductive connector  40  then the assemble-connecting is completed. After the 110V or 220V AC power is passing through left, right copper plug pins  11 ,  12  and fuse  20 , the AC is rectified by the left, right rectification diodes  30 ,  31  into DC (direct current) power then provided to the third electrical wire  52 . And, the third wire  52  is connected to one or more circuits of LED lamp strings&#39; circuitry. 
       FIG. 5  shows a composing structural diagram of a tail-plugging socket in the present invention while having two conductive wires. It has left, right compartment  601 ,  602  formed in two sides of a base  60  and has a housing hole&#39;s seat  603  set at a site close to the center, and left, right terminal plates  61 ,  62  set with electrical wires  50 ,  51  are separately laid in the left, right compartment  601 ,  602 .
