Embodiment

As shown in Figures 2 and 3, but the electric supply installation of the automatic cut-off loop of present embodiment includes a direct current joint 10 and an attaching plug.

With reference to Fig. 3, Fig. 4 and Fig. 5, this direct current joint includes a joint housing 11, a starting switch and a DC output end 40, joint housing 11 hollows and include a room.

Starting switch is located in the room of joint housing 11, and it includes a sleeve 20, a conducting element 22, a movable part 30, first conducting strip 31 and second conducting strip 32.

This sleeve 20 is installed in joint housing 11 rooms, is provided with a shrink-fit structure 21 in sleeve 20, annular flange flange 23 in an openend inner edge of sleeve 20 is provided with.

Conducting element 22 is installed in the room of joint housing 11, the movable part 30 of present embodiment this sleeve 20 relatively slidably reciprocates, being formed with one on movable part 30 is positioned at sleeve 20 and can makes movable part 30 break away from shells 11 against the outer annular flanges 23 of sleeve 20, movable part 30 is provided with first conducting strip 31 and closes second conducting strip 32, this first and second conducting

strip

31,32 is respectively positive and negative electrode, and connects first lead 1 and second lead 2 respectively.

Spring 50 is arranged in the sleeve 20, and an end is against the outer annular flanges 33 of movable part 30, and the other end makes it to separate conducting element 22 and first and second lead 1,2 under the situation of no external force effect against sleeve, and the reset effect of movable part 30 is provided.

This DC output end 40 is arranged on movable part 30 ends, which is provided with two conducting positions 41,42, lead a position 41,42 for not connecting privates 3 and privates 4, wherein privates 4 one ends connect negative pole, the 3rd with privates 3,4 as a supply line, wherein first, second, third, fourth lead 1,2,3,4 passes plug casing 11.

With reference to shown in Figure 6, among the figure equivalent circuit diagram of present embodiment, wherein this attaching plug includes a plug body 60, an electric pressure converter 61, a direct current transducer 62 and a broken-circuit controller 63.

Plug body is provided with the tank that totally first, second, third, fourth lead 1,2,3,4 stretches into.

This electric pressure converter 61 is arranged on tank.Have two inputs, an input connects one of AC power input, and another input then connects second lead.
