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.
SUMMARY OF THE INVENTION
The present invention is to provide a socket structure of current-rectifiable lamp string and especially is aimed at a socket set with rectification diodes. Its features are that one pin of the left and right rectification diodes along with wires inside the socket are clamped on the left and right terminals and the other pin are rivet-assembled with one conductive connector to form a mutually conducting status. It thus can solve the problem of inconvenience in constructing caused by the former welding method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Please firstly refer to those shown in FIGS. 1 and 2, which disclose a structure while the front plugging socket has two conductive wires. It includes a base 10, left, right copper plug pins 11, 12, left, right copper seats 13, 14 connect-setting with wires 50, 51 and fuses 20. 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'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. The anode (positive pole) end pins 301, 311 of left, right rectification diodes 30, 31 along with electrical wires 50, 51 are separately clamped on the left, right copper seats 13, 14, and the cathode (negative pole) end pins 302, 312 are laid at two sides in the opening of housing hole's seat 104. The conductive connector 40 is then inserting into the housing hole's seat 104, and the outward-bent conductive connecting plate 41 in the top end of conductive connector 40 is rivet-assembled separately with the cathode (negative pole) end pins 302, 312 of the left, right rectification diodes 30, 31 such that the left, right rectification diodes 30, 31 form a conducting status. It thus can solve the problem of inconvenience in constructing caused by adopting the welding method in the prior art.
Please refer to FIGS. 3 and 4 that are a structure and assembling method while the front plugging socket has three conductive wires. 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' 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'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. And, the cathode (negative pole) end pins 301, 311 of left, right rectification diodes 30, 31 along with electrical wires 50, 51 are clamped separately on the left, right terminal plates 61, 62, and anode (positive pole) end pins 302, 312 are laid at two sides in the opening of housing hole's seat 603. The conductive connector 40 is then inserting into the housing hole's seat 603, and the outward-bent conductive connecting plate 41 in the top end of conductive connector 40 is rivet-assembled separately with the one end pins 302, 312 of the left, right rectification diodes 30, 31 such that the left, right rectification diodes 30, 31 form a conducting status. And, while assemble-connecting with a third electrical wire, it also just requires to insert the copper wire portion in the third electrical wire 52 directly into the through hole 42 of conductive connector 40 then the assemble-connecting is completed. Let the third electrical wire of tail-plugging socket and the third electrical wire of front-plugging socket connect together to one or more circuits of LED lamp strings' circuitry. After the DC current of the third electrical wire in the front-plugging socket is passing through the LED lamp string, the DC is transferred into AC by the left, right rectification diodes 30, 31 of tail-plugging socket such that more LED lamp strings can be connect-inserted to this lamp string.
