The specific embodiment

The utility model is further specified as follows below in conjunction with accompanying drawing and most preferred embodiment:

As shown in Figure 1, the utility model is pegged graft mutually by some joint Transparent lamp tubes 2 and is formed the rope lamp of certain-length, and the two ends of this rope lamp join with power plug wire 1 and terminal plug 3 respectively.Be equipped with a transparent interior pipe 6 in described every joint Transparent lamp tube 2, should be installed with bulb group 21 and lead 22 in the interior pipe 6, there are female head and male connector 23 in the two ends of described fluorescent tube injection mo(u)lding respectively, 24, there is pin 235 to cooperate in the female connector 23 with the pin 245 of male connector 24, be with octagon nut 232 on the outer wall of female connector 23, this octagon nut upper edge receptacle ends direction has protruded out 2 catch 233, and these octagon nut two ends are respectively by the flange backstop in described female head or the male connector, the end of its male connector 24 forms the external screw thread 242 that cooperates with this octagon nut, and the periphery wall of male connector flange 241 is provided with 4 unidirectional backstop projections 243 with catch 233 corresponding matching.When the female connector of a joint fluorescent tube is connected with the male connector of another joint fluorescent tube, octagon nut 232 rotation sets of female socket end are advanced on the external screw thread 242 of male socket end, close up and can not throw off easily up to catch 233 and projection 244, finish the linking between fluorescent tube at this point.If will throw off fluorescent tube or change fluorescent tube, then must catch 233 upwards be levered up with instrument, unscrew nut then, can arbitrarily change fluorescent tube.As shown in Figure 2, on the lead in power plug wire 1 and the socket fluorescent tube cohesive end, be connected with fuse 13, reach safe handling in order to the control current overload.The socket of this power line and fluorescent tube cohesive end is made as female connector, and its basic structure is identical with the female connector of lamp tube end.In order further to reach good waterproof effect, flange 231 1 sides that cooperate with male connector in female connector are fixed with waterproof washer 4, and the grafting along with the male and female pin during assembling cooperates, and this packing ring is pressed between male-female sockets.For the reinforced insulation performance, also add heat-shrinkable T bush 5 on pin 245,235 in female head and male connector and the lead.The fluorescent tube end of this rope lamp is made as female connector, plug 3 is sealed by an end, the tarpaulin 31 of other end opening the have externally threaded stifle 32 external with being sleeved on this cap formed, the external screw thread of described stifle 32 and flanged structure are identical with male connector, thereby can closely cooperate with the octagon nut 232 of female connector.The external wall of described tarpaulin is smooth, and its internal diameter size just in time tightly is enclosed within the end of female connector 23, and in order to be nested with firmly, the inwall of this cap body is provided with 3 convex tendons, and the blind end of described stifle is jug 321 also.

Octagon nut described in the above-mentioned most preferred embodiment also can be replaced by hex nut, and the catch on the described nut (233) also can be 3 or 4, and the unidirectional backstop projection (243) in the described male connector (24) also can optionally be replaced by 2,3 or 5.

The utility model is not limited to the described structure of the foregoing description, and for a person skilled in the art, the change of in claim institute restricted portion the utility model being made all should belong to category of the present utility model.
