Embodiment

In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.

For making to understand structure of the present utility model more in detail, refer to shown in Fig. 1 to Fig. 4, the utility model provides a kind of plug construction, it includes a main body 1, this main body 1 is hollow cylindrical and has front end 11 and tail end 12, main body 1 front end 11 is arranged with two corresponding breach 13 and two corresponding pinch plates 14 are extended in front end 11 simultaneously, and main body 1 internal perisporium is provided with two symmetry and the fin 15 alignd for conllinear with aforementioned breach 13;

One power line 2, it includes positive wire 21 and a cathode wire 22, and this positive wire 21 one end is provided with an anode termination 210, and cathode wire 22 one end is around being snail shape and being provided with a negative electrode termination 220, as shown in Figure 4;

One flexible rib 3, it is the flexible rib 3 of a conductive material, this flexible rib 3 includes a U-shaped portion 31, and two ends of this U-shaped portion 31 extend the end pin 33 of suitable length respectively, and protrudes two half corresponding camber arch form portions 32 between two ends pin 33 with U-shaped portion 31 laterally; The negative electrode termination 220 that one end pin 33 of flexible rib 3 is first snail shape through cathode wire 22 one end of aforementioned power source line 2 is located in by the U-shaped portion 31 of flexible rib 3 and is contacted with on negative electrode termination 220 (can as shown in Figures 3 and 4); Power line 2 another end autonomous agent 1 tail end 12 being combined with flexible rib 3 passes and another device (not shown) external, and flexible rib 3 is inserted in main body 1, U-shaped portion 31 outer rim of its flexible rib 3 contacts at two symmetrical fins 15 of main body 1 internal perisporium, and the arch form portion 32 of half camber protrudes from two breach 13.

One lid 4, it is concaved with two and symmetricly wears mouth 41, the extension of this lid 4 medial surface centre is provided with a hollow posts 42, this hollow posts 42 is provided with a through hole run through completely 420, to extend internally out a bulge loop wall 421 in hollow posts 42 end, and form a ring between hollow posts 42 and lid 4 madial wall and receive groove 43;
