Embodiment

Below in conjunction with drawings and Examples, the present invention is described in detail.

Overall structure of the present invention as shown in Figure 1, when lamp tube electrode 9 packs into, the step surface of lamp tube electrode 9 promotes translation piece 8, enter in the guide groove of housing 2, now, because compact heap 5 and subdivision electrode 4 are subject to the elastic force effect of spring 6, therefore compact heap 5 does not contact with subdivision electrode 4, subdivision electrode is in malcompression state, and lamp tube electrode 9 can insert among two subdivision electrodes 4 smoothly.

Axial positioning mechanism as shown in Figure 2, fluorescent tube continues to move downward, promoting translation piece 8, spill spin block 7, spring 6 and subdivision electrode 4 moves downward, when moving down after certain distance, spill spin block 7 departs from the guide groove of housing 2, because of the effect of translation piece end helical teeth and spring 6 elastic force, spill spin block 7, by snapping in helical teeth along the canine tooth of housing 2 guide groove ends, no longer moves.Now two subdivision electrodes 4 are subject to the pressure of compact heap 5 and hold tightly, and the cylinder electrode that lamp tube electrode 9 protrudes also will be held tightly, completes insertion state.In addition, for preventing lamp tube electrode 9 dropping distances compared with hour just being held tightly and cannot complete spill spin block rotation by subdivision electrode 4, adding buffer spring 34 times at subdivision electrode, is that lamp tube electrode 9 still can continue to decline.

When fluorescent tube is extracted, promote lamp tube electrode 9, lamp tube electrode 9 step surfaces promote translation piece 8 and spill spin block 7 moves downward, when moving down after certain distance, spill spin block 7 departs from the guide groove of housing 2, because of the effect of translation piece 8 pitch faces, housing 2 end little tooth inclined-planes and spring 6 elastic force, spill spin block 7 will rotate to an angle, and reenter in the guide groove of housing 2.Now, due to the elastic force effect of spring 6, compact heap 5 reduces gradually with the power of subdivision electrode 4, while getting back to initial position, just separates, and at this moment lamp tube electrode 9, in releasing orientation, can exit smoothly.While extracting due to lamp tube electrode 9, need to press down a bit of distance, for preventing moving down, buffer spring 3 is set, make the axial positioning mechanism can normal running.

Owing to will realizing the design of the large electric current of low thrust, when electric current is excessive, in order to guarantee fail safe, require contact portion resistance enough little, and contact portion resistance sizes and Surface Contact pressure are inversely proportional to, Surface Contact pressure is larger, and contact resistance is less.Limited when thrust, while requiring large electric current, can provide enough large contact by adjusting taper angle, make it to satisfy condition.Wherein the general relationship of electric current and taper angle is:

$\mathrm{\θ}\≤\mathrm{acr}\tan \left(\frac{{\mathrm{FI}}^2}{C}\right)$

Wherein, F is thrust, and unit is ox; I is electric current, and unit is ampere; θ is taper angle, and unit is degree; C is constant, gets 100000.

Be illustrated in figure 3 subdivision electrode 4 structure charts, wherein upper end semicircle orifice act as and holds lamp tube electrode tightly, and ramp effect is for increasing contact, and end cone tank is set for connecing external power electrode.

The various embodiments described above are only for illustrating the present invention, and wherein structure, the connected mode etc. of each parts all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement, all should not get rid of outside protection scope of the present invention.
