Embodiment

As shown in Figure 1, ground connection at first in the plug insertion process, the prime single-pole double-throw switch (SPDT) is got to the upper end then, make plug by the electric capacity energising that is connected with power supply, indicator light is bright, capacitor fast charging, the electric capacity both end voltage rises to 220 volts, next step short switch closure, and power supply is directly switched on to plug, electric capacity is by short circuit, indicator light extinguishes, the electric capacity repid discharge, and the electric capacity both end voltage is reduced to 0 volt, utilize the capacitor fast charging discharge to realize quick changes in voltage in the whole process, avoid sparkover.

Divide three phases to be described further embodiment in conjunction with other accompanying drawing more below.

Stage one, shown in Fig. 3-1, when jack 2 certain depths are injected at the plug two ends simultaneously with patch core 4 in advance and contact, patch core 4 and patchplug 8 one in advance, patchplug 8 was connected with grounding contact 17 in this stage, thereby plug is in ground state, and plug continues to inject and promotes position limiting slide block 6 and leave, this moment, socket panel 2 integral body can glide along limited post 9, and plug inserts and be about to be in "on" position fully.

Stage two, shown in Fig. 3-2, continue to promote plug downwards, make top, 8 liang of outer ends of patchplug leave grounding contact 17, and make bottom, 8 liang of outer ends of patchplug insert one-level lock pin 16, this moment, plug was by electric capacity 15 and power turn-on, electric capacity can be stored a large amount of electric charges in the short time, can avoid sparkover, and this stage plug is in indirect "on" position, indicator light 14 is bright, and back-moving spring 2 is in compressive state.

Stage three, shown in Fig. 3-3, continue to advance plug downwards, insert secondary lock pin 13 up to bottom, 8 liang of outer ends of patchplug, and offset with baffle plate 10, this moment, plug had been inserted into lowermost end, loosed one's grip, and the elastic force of frictional force and back-moving spring 2 balances each other and makes plug stay in this position between dependence one-level lock pin 16, secondary lock pin 13 and the patchplug 8, this stage plug is in direct "on" position, electric capacity is by patchplug 8 short circuits, and indicator light extinguishes, and back-moving spring further is compressed.

Unplugg is above-mentioned three stage inverse process, for simplicity's sake, no longer repeats.

Above-mentioned jack panel 1 is sliding up and down in the process along limited post 9, and topmost the position is determined by position limiting slide block 6, this moment patchplug 8 normal ground connection, lowest positions determines that by baffle plate 10 jack panel 1 top still is positioned at position limiting slide block 6 tops at this moment.

Owing to adopt patch plug device, making that socket is inside and outside isolates, provide patch plug device downslide lower limit simultaneously at the reservation baffle plate in addition, baffle design becomes tilt mode, can effectively prevent the generation of socket short circuit under the unexpected flooded condition of socket, jack panel 1, plate base 5, position limiting slide block 6, limited post 9, bottom plug 12 all adopt insulator.

Secondary power on/off device relies on electric capacity 15 to prevent sparkover, and can indicator light 14 is used for observing electric capacity operate as normal, if indicator light 14 extinguishes all the time, illustrates that electric capacity 15 breaks down, and should in time change electric capacity 15.
