[ description of the drawings ]
Fig. 1 is a schematic circuit diagram of a dc socket according to the present invention, which is powered on and powered off after the plug is inserted.
[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the present invention provides a dc socket with a plug inserted therein and then powered off before being plugged out, including: insulating casing 1, locate and be used for 2 inserted sheet male anodal shell fragment 3, negative pole shell fragment 4, directional shell fragment 5 of plug in insulating casing 1, anodal shell fragment 3, negative pole shell fragment 4, directional shell fragment 5 and power electricity are connected, still include: a contactor and a travel switch 6, the contactor comprising: contactor contact 7, contactor coil 8, contactor contact 7 is located between anodal shell fragment 3 and the power, 8 negative poles of contactor coil are connected with the power negative pole electricity, anodal and the 6 one end electricity of travel switch are connected, the 6 other end of travel switch is connected with the power anodal electricity, it is equipped with a logical groove 9 to lie in between negative pole shell fragment 4 and the travel switch 6 in insulating casing 1, insulating touching end 10 tip is worn out in negative pole shell fragment 4 after stretching out in logical groove 9, diode 11 reverse parallel connection is in 8 both ends of contactor coil.
Particularly, the width of the end part of the insulated touch end 10 is not more than the distance between the negative elastic pieces 4; by the design, after the inserting piece is inserted into the socket, the end part of the inserting piece is completely contacted with the insulating touch end 10, so that smooth electrification is ensured.
Specifically, the length of the insulating touch end 10 is not less than twice that of the through groove 9, and the insulating touch end 10 extends out of the through groove 9 by not more than half of the insulating touch end 10; by the design, the travel switch can be further ensured to be in an open state when the plug is not inserted or not completely inserted, so that the circuit is ensured to be in a non-electrified state, and the power utilization safety is ensured.
In the utility model discloses in, the model of contactor, diode requires to match through voltage current.
The working principle is as follows:
when the plug is not inserted, the travel switch contact is opened, the coil of the contactor is in a power-off state, the contactor contact opens the positive elastic piece to be disconnected from the power supply without electricity, and the positive elastic piece is in a power-off state.
When the plug is inserted into the socket, the plug insert firstly contacts the positive elastic sheet, the negative elastic sheet and the directional elastic sheet, when the plug is inserted into a certain position, the plug insert and the socket elastic sheet are in sufficient contact at the moment, the stroke switch insulating contact end is touched, the stroke switch contact is closed, the contactor coil is electrified through the stroke switch contact, the driving contactor contact is closed at a normally open point, the positive elastic sheet is electrified with the power supply side, the plug phase line insert and the power receiving side are electrified, and the socket and the plug form a circuit loop communication state.
When the plug is pulled out of a certain position of the socket, the plug insert side wall is in contact with the socket elastic sheet side wall at the moment, the end part of the plug insert leaves the travel switch insulating touch end, the travel switch contact is opened, the contactor coil loses power, current is released through the diode, the contactor contact is opened, the socket positive elastic sheet is disconnected from the power supply side and loses power, the plug positive insert and the power receiving side lose power simultaneously, the socket and the plug form a circuit loop disconnection state, the plug is continuously pulled out until being pulled out of the socket, electric sparks and arcing cannot be generated in the process, and therefore power utilization safety is improved.
