As improvement, a kind of pull-switch is again disclosed in prior art, see that the patent No. is the Chinese utility model patent " button pull-switch " (Authorization Notice No. is CN202695749U) of ZL201220245602.X, although this patent is free-hand can complete installation, but ordinary person's operation is still convenient not, overall structure is comparatively complicated simultaneously, and manufacturing cost is higher, not easily promotes.

Utility model content

Technical problem to be solved in the utility model provides a kind of fast-wiring switch without the need to peeling.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of fast-wiring switch, is characterized in that comprising

Hold line shell, at least there are two appearance string holes roads stretched into for wire;

Conductive shaft, being located at rotationally on aforesaid appearance line shell and running through by aforesaid appearance string holes road, outer end has a knob, and the portion perimeter curved surface of this conductive shaft is isolation material; And

Line pressing rod, at least two, corresponding respective energy one end, appearance string holes road is located at rotationally on aforementioned appearance line shell and is also built-in with presser thread needle respectively, and this presser thread needle has the tip of stretching out downwards, and this presser thread needle one end can contact conducting with aforesaid conductive shaft and aforesaid appearance string holes road can be stretched in tip.

As preferably, described conductive shaft comprises

Conductive tube, hollow also alongst forms a v notch v; And

Insulating part, comprises bar portion and takes shape in the knob of one end, bar portion, and this bar portion to be arranged in aforesaid conductive tube and to fill aforesaid bar v notch v to make conductive tube portion perimeter curved surface for isolation material.

Here conductive tube and insulating part can integrated through injection molding, also can divide body formed after be assembled into one.

Described conductive tube one end forms a limiting section expanded, assembling or shaping time limiting section play the effect of spacing insulating part.

Further, described appearance line shell forms the bar-shaped trough arranged for line pressing rod

Compared with prior art, the utility model has the advantage of: presser thread needle by conductive shaft by two wire conductings, knob drives conductive shaft to rotate simultaneously, can realize the break-make of conductive shaft and presser thread needle, to reach switching function, overall structure is simple, when installing, hold line shell as long as inserted by wire, then close line pressing rod simultaneously, the cortex that presser thread needle pierces through wire contacts conducting with metallic member, convenient and swift.

Embodiment

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.

As shown in Figure 1 to 4, the fast-wiring switch in the present embodiment comprises and holds line shell 1, conductive shaft and line pressing rod 2, holds line shell 1 and has two appearance string holes roads 11 stretched into for wire 10, hold on line shell 1 and form two bar-shaped troughs 12.Conductive shaft can be located at rotationally and hold on line shell 1 and run through by holding string holes road 11, and outer end has a knob 42, and the portion perimeter curved surface of this conductive shaft is isolation material.Line pressing rod 2 is two, corresponding respective appearance string holes road 11 can be located on appearance line shell 1 in one end rotationally, line pressing rod 2 is adaptive with bar-shaped trough 12, each line pressing rod 2 is built-in with presser thread needle 3 respectively, this presser thread needle 3 has the tip 31 of stretching out downwards, and this presser thread needle 3 one end can contact conducting with conductive shaft and tip 31 can be stretched into and holds string holes road 11.

Conductive shaft comprises conductive tube 51 and insulating part 4, conductive tube 51 hollow also alongst forms a v notch v 53, afterbody has the limiting section 52 expanded, insulating part 4 comprises bar portion 41 and takes shape in the knob 42 of one end, bar portion 41, and this bar portion 41 is arranged at the interior also packing v notch v 53 of conductive tube 51 to make conductive tube 51 portion perimeter curved surface for isolation material.Conductive tube 51 and insulating part 4 can integrated through injection molding.

Shown in composition graphs 5 and Fig. 6, during installation, hold line shell 1 as long as inserted by wire 10, then close line pressing rod 2, and presser thread needle 3 pierces through the cortex of wire 10 and contacts conducting with metallic member, shown in composition graphs 7 and Fig. 8, when switch cuts out, as long as turning knob 42, knob 42 drives conductive shaft to rotate, isolation material part on conductive shaft contacts with presser thread needle 3, realizes open circuit.Reverse operating again, the conductive tube 51 on conductive shaft contacts with presser thread needle 3, realizes path.
