Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the socket schematic diagram of the utility model extinguishing arc type plugs and sockets embodiment.
Fig. 2 is the plug construction schematic diagram of the utility model extinguishing arc type plugs and sockets embodiment.
In figure, 1-first socket, 2-second socket, 3-the 3rd socket, 4-the 4th socket, 5-the 5th socket, 6-first plug, 7-second plug, 8-the 3rd plug, 9-the 4th plug, 10-the 5th plug, the KT-alternating current die mould time relay, T-AC transformer, L-live wire, N-zero line.
Embodiment
Fig. 1 is a kind of extinguishing arc type socket, and Fig. 2 is plug supporting with it.
T in the socket of Fig. 1 is AC transformer, and the alternating voltage of 220V can be changed into the alternating voltage of 5V, KT is the alternating current die mould time relay, and after coil adds the alternating voltage of 5V, the normal opened contact of 2S time KT closes.
In socket, first socket 1 is connected with one end of the secondary coil of AC transformer T by the coil of alternating current die mould time relay KT, second socket 2 is connected with the other end of the secondary coil of AC transformer T, 3rd socket 3 is connected with one end of the primary coil of AC transformer T by the joint of often opening of alternating current die mould time relay KT, 4th socket 4 is connected with the other end of the primary coil of AC transformer T, the 5th socket 5 ground connection; The two ends of the primary coil of AC transformer T are connected with the live wire L of AC power and zero line N respectively.
Plug in Fig. 2 has five binding posts, and wherein the 5th plug 10 is protective earthing joint, and the 3rd plug 8 is the joint of live wire L, and the 4th plug 9 is the joint of zero line N, and these three joints are identical with ordinary plug.First plug 6 and the second plug 7 plug particular design part for this reason, these two joints connect at plug inside wire, form the state of short circuit.
After in plug insertion socket, the first plug 6 in plug is plugged together with the first socket 1 on socket, second plug 7 and the second socket 2 are plugged together, 3rd plug 8 and the 3rd socket 3 are plugged together, 4th plug 9 and the 4th socket 4 are plugged together, and the 5th plug 10 and the 5th socket 5 are plugged together.
When plug insertion socket moment, because KT contact is in open mode, so the 3rd socket 3 does not have voltage, so can not electric arc be produced.Because the first plug 6 on plug and the second plug 7 are short circuits, the first socket 1 on socket is inserted again due to the first plug 6, second plug 7 inserts the second socket 2 on socket, the loop at KT coil place forms path, the coil of time relay KT is coupled with the alternating voltage of 5V, the time delay 2S time, the normal opened contact of the time relay closes, thus the 3rd socket 3 on socket is connected with live wire L, the 3rd plug 8 on plug is inserted in the 3rd socket 3 on socket, so, now the 3rd plug 8 of plug is also connected with live wire, the alternating voltage of 220V is just added between the 3rd plug 8 and the 4th plug 9 of plug, thus make the normal charged use of electrical equipment, avoid the generation of electric arc.
In plug, first plug 6 and the second plug 7 are than other the 3rd plug 8, the length of the 4th plug 9 and the 5th plug 10 is slightly short, like this, when plug is extracted from socket time, first plug 6 and the first socket 6, second plug 7 and the second socket 2 coupling part are than the 5th plug 10 and the 5th socket 5, 3rd plug 8 and the 3rd socket 3, the coupling part of the 4th plug 9 and the 4th socket 4 first disconnects, due to the first plug 6 and the first socket 6, second plug 7 and the second socket 2 coupling part disconnect, the coil losing electricity of time relay KT, the contact of KT is opened, in the 3rd plug 8 and the 3rd socket 3 coupling part by dead electricity before separately, when moment is separately pulled out in the 3rd plug 8 and the 3rd socket 3 coupling part, in fact between the 3rd socket 3 and the 4th socket 4, voltage is not had, ensure that and also to produce without electric arc when unpluging plug from socket.
Above-described the utility model execution mode, does not form the restriction to the utility model protection range.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within claims of the present utility model.
