The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., only refer to the direction of the additional drawing. Therefore, the directional terminology used is used to illustrate that it is not intended to limit the creation. 7 M352048 Please refer to the figure ’ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ ─ The lamp holder includes a tube body and an electrode 340. The electrode 340 is electrically connected to the end of the tube 32〇. The material of the electrode 340 can be a conductive material such as a gold wire, for example, the wrong line _ by the lamp holder 200 includes an insulating body 22 and a conductive strip. . The insulative housing 22 can be spaced 226 by rotating or other resilient insulating material. The groove 222 has a bottom surface ^ for placing the conductive strip 24G. In this embodiment, the insulating body further includes a positioning groove 22i'. The positioning groove 221 is located at the end of the groove 222. In another embodiment, the insulating body 220 is body-formed to form the positioning groove 221, the grooved groove, the broadcast piece 224, and the fixed space 226. In the present embodiment, the conductive strip has a trap chamber, and the portion of the bottom surface 222a of the recess is recessed to form a receiving groove 228 for the recess of the conductive strip 240 to be woven therein. The groove 222 has a side wall, and the dam 224 is visible to the eye, and is respectively erected on the side of the accommodating groove 228. The piece 224 is located between the nano-slot 228 and the fixed space 226 to block the holding groove and the fixed space. The /block 224 provides a notch 224a' that allows the receiving slot 228 to communicate with the mosquito space 226 through the notch 224a of the flap 224. The conductive strip 240 can be a long strip of copper or a metal material of other conductivity: the purchase of the conductive strip 24 of the conductive strip 24, which is the arc of the conductive strip (10) 'The degree of bending is suitable for being placed in the M352048 of the receiving groove 228 and is sufficient for the electrode 340 of the lamp tube 300 to be placed therein. It is worth mentioning that the conductive strip 240 has a positioning member for snapping into the positioning groove 221 of the insulating body 22〇. In one embodiment, the conductive strip 240 can be bent into an L-shaped structure that includes a strip 242 and a short strip 244 with the strip 244 as the locating member. Referring to FIG. 3B, the structure of the lamp tube 300 and the lamp holder 2〇〇 is shown. For convenience of explanation, FIG. 3B does not show the side wall 222b of FIG. 3A. When the end portion 322 of the tube body 320 of the tube 3 is inserted into the fixing space 226 of the insulative housing 22, the insulative housing 220 grips the tube 32 of the lamp f 3〇〇 by its own elastic force. The electrode 340 is in contact with the recessed portion of the conductive strip through the notched island of the flap 224. The recess is adapted to receive a solder for soldering the conductive strip to the electrode 340 of the tube 300 to form a tan junction 4 (8). As shown in Fig. 4, compared with the Tan connection in the ton of the ton, compared with the point-carrying structure, in this embodiment, the thin circumferential surface of the electrode of the lamp is in contact with the curved curved surface of the depressed portion, so that the electrode 340 is larger. The surface area is in contact with the conductive strip 240, and the electrode alone and the conductive strip 240 are not easily phased in the welding process, so that the welding can be avoided. In addition, since the electrode 3 has a small portion of the surface indentation a after the electrode (4) is placed in the recessed portion, and the gravure tin is added, it is easier to completely cover the electrode. Referring to FIG. 3A in May, when the recessed portion 2 of the conductive strip is placed into the receiving portion 228 of the insulative housing 220, the crucible is cut, the 汲罝'ba margin and the 224 piece are Yang Hu 2 and his opposite two The opening is 224 _ by the side wall 222b, and the axis is set to the axis, so that the capacity of the solder in the mother-recessed portion is substantially equal, so that the cost of the solder is preliminarily controlled. In addition, the cymbal piece 224 can be made of a heat insulating material. Since the damper 224 is formed to block the accommodating groove 228, the sealing space is fine. Therefore, during the welding process, the cymbal piece 22 prevents the lower temperature tube from contacting the high temperature solder. Or with the exception of: the temperature of tin is still abnormal. Referring to the figure and FIG. 4, the long strip portion 242 of the conductive strip 24G is placed on the bottom surface of the insulating 2 whip, and the short strip portion 244 is inserted into the insulating layer.
