Detailed Description
The present invention will be further described with reference to the following drawings and examples, which may be typical:
the electric connection device comprises a controller 1, wherein the controller 1 is provided with a controller input end which is used for connecting with a mains supply output port of an energy storage power supply, and the controller 1 is also connected with a plug 2 which is used for connecting with a mains supply socket;
the plug 2 is provided with a pin 21, and the surface of the plug 2 facing the socket is provided with a safety switch part, so that when the plug 2 is inserted into the socket, the safety switch part is triggered to be in a first state, and the input end of the controller is communicated with the pin 21; when the plug 2 is pulled out of the socket, the safety switch part is triggered to be in a second state, so that the input end of the controller is disconnected with the plug pin 21.
The electric connection device is used for safely establishing power supply connection and is mainly suitable for the scene of commercial power voltage. Most typically, when a house has a power failure, the energy storage power supply safely supplies power to a household mains supply socket, and the plug is ensured to be electrified after being inserted into the socket, so that the electric shock risk is avoided.
As shown in fig. 1 and 2, a controller 1 is provided with a controller input end, and the controller input end is used for connecting a mains supply output port of an energy storage power supply. Specifically, in the embodiment shown in fig. 1, the input end of the controller is a delta socket 11, and when the controller is used, a delta power line can be used, one end of the delta power line is connected to a mains supply output port of the energy storage power supply, and the other end of the delta power line is connected to the delta socket 11 of the controller 1, so that connection is achieved.
The pin plug of the pin power line has no exposed metal contact, which can reduce the risk of electric shock, and the input end of the controller can also adopt other safe sockets, for example, the input end of the controller can be the male plug of the aviation plug. The adaptive cable with the aviation plug female head is used for connecting the energy storage power supply and the controller, namely the aviation plug female head is connected with the input end of the controller, and the other end of the cable is connected with a mains supply output port of the energy storage power supply. Because the metal contact of the aviation plug female head is not exposed, the electric shock risk can be reduced.
Or, the input end of the controller may be an input cable of the controller 1, and a plug is disposed at an end of the input cable and may be connected to a mains supply output port of the energy storage power supply.
The controller 1 is further connected with a plug 2 for connecting with a commercial power socket, the plug 2 may be directly arranged on the controller 1, or as shown in fig. 1, the controller 1 is connected with the plug 2 through a section of cable.
The surface of the plug 2 facing the socket, as shown in fig. 1 and 2, refers to the surface facing the socket when the plug 2 is inserted into the socket, and the surface is provided with a safety switch portion, when the plug 2 is inserted into the commercial power socket, the pin 21 enters the jack of the socket, and the surface of the plug 2 facing the socket abuts against the socket, so that the safety switch portion is triggered.
The safety switch part is in a first state, the input end of the controller is connected with the plug pin 21, the energy storage power supply supplies power to the mains supply socket, the lamp in the house can get electricity to work, and the small-sized electric appliance can get electricity from other sockets.
When the plug 2 is pulled out of the socket, the safety switch part is separated from triggering, and is in a second state, so that the input end of the controller is disconnected with the pin 21, and people can not get an electric shock even if touching the pin 21 of the electric connection device.
More specifically, to achieve the above-mentioned function, one possible solution is that, for example, the part of the pin 21 located in the insulator of the socket 2 is the pin tail;
a metal elastic sheet is arranged in the socket 2, one end of the metal elastic sheet is connected with the input end of the controller, and the other end of the metal elastic sheet is close to the tail part of the pin; the surface of the plug 2 facing the socket is provided with a pin hole, an insulating pin column is arranged in the pin hole, the inner end of the insulating pin column is abutted against the metal elastic sheet, and the outer end of the insulating pin column extends out of the surface of the plug 2 facing the socket.
When the plug 2 is inserted into the commercial power socket, the insulating pin column is extruded to move towards the direction of the metal elastic sheet, and then the metal elastic sheet is extruded to be close to and contact the tail part of the pin, so that the input end of the controller is communicated with the pin 21, and the energy storage power supply supplies power to the commercial power socket. When the plug 2 is pulled out from the socket, the elastic force of the metal elastic sheet makes the metal elastic sheet separate from the tail part of the pin, the input end of the controller is disconnected with the pin 21, and the pin 21 is not electrified any more.
More preferably, the related functions may be realized by a relay, for example, the controller may include a power supply module, a control module, and a relay unit;
the input end of the controller is connected with the plug to form a commercial power supply path, and the relay part is arranged on the commercial power supply path and used for controlling the on/off of the commercial power supply path;
the power supply module is respectively connected with the input end of the controller and the safety switch part and is used for receiving the commercial power from the input end of the controller and supplying power to the safety switch part after voltage reduction and rectification;
the power supply module is further connected with the relay part to form a relay power supply path for the power supply module to receive commercial power from the input end of the controller and convert the commercial power into adaptive voltage to supply power to the relay part, the control module is arranged on the relay power supply path, and the safety switch part is connected with the control module and used for the control module to receive a trigger signal of the safety switch part and further control the relay power supply path to be switched on/off.
As shown in fig. 3, the functional modules of the controller include a power supply module, a control module, and a relay part.
The relay part is arranged on the commercial power supply path and used for controlling the commercial power supply path to be switched on/off, for example, when the relay part is electrified and attracted, the input end of the controller is switched on with the plug, and the energy storage power supply supplies power to the commercial power socket; when the relay part is disconnected and released, the input end of the controller is disconnected with the plug.
The relay unit may be implemented by using one relay, or may be implemented by connecting a plurality of relays in series. For example, the relay part may include two relays connected in series to the mains supply path, and when the two relays are simultaneously energized and switched on, the energy storage power supply supplies power to the mains supply socket; when any relay is disconnected and released, the input end of the controller is disconnected with the plug. In the above preferred scheme, if a single relay fails to cause error suction, the input end of the controller and the plug are still in open circuit, and the safety can be improved.
The power supply module is used for acquiring mains supply and converting the mains supply into appropriate voltage to supply power for the relay part and other auxiliary circuits. As shown in fig. 3, the input end of the power supply module is connected to the input end of the controller, that is, the power supply module is connected to the mains outlet of the energy storage power supply to obtain the mains voltage.
The power supply module has two paths of outputs, wherein one path of output is to convert commercial power into adaptive voltage to supply power to the relay part, the adaptive voltage is determined according to the model of the used relay part, and most typically, the adaptive voltage is converted into direct current 12v to supply power to the relay part.
The other output of the power supply module is to convert the commercial power into low-voltage direct current to supply power to the safety switch part and other auxiliary circuits, and the direct current can be 5v or 3.3v.
The control module is arranged on a power supply path of the relay, when the safety switch part is triggered and is in a first state, the control module receives a trigger signal of the safety switch part, then the control module is switched on to supply power to the relay part, the relay part is switched on and closed, and the energy storage power supply is switched on to supply power to the mains supply socket. When the safety switch part is in the second state, the control module does not receive the trigger signal of the safety switch part, the power supply module is disconnected to supply power to the relay part, the relay part is powered off and released, and the energy storage power supply stops supplying power to the commercial power socket.
More specifically, the safety switch portion may be implemented by a tact switch or a photoelectric switch, for example, the tact switch is disposed on a surface of the plug 2 facing the socket as the safety switch portion, and when the plug 2 is inserted into the commercial power socket, the tact switch is triggered by being pressed, and when the plug 2 is pulled out from the commercial power socket, the tact switch is triggered by being released from the pressing.
Similarly, if the surface of the plug 2 facing the socket is provided with the photoelectric switch as the safety switch part, when the plug 2 is inserted into the commercial power socket, the photoelectric switch cannot receive the illumination and is triggered, and when the plug 2 is pulled out from the commercial power socket, the photoelectric switch receives the illumination and stops triggering.
More preferably, the safety switch unit may include the photoelectric switch 22 and the tact switch 23 connected in series, and for example, two switches in total of the photoelectric switch 22 and the tact switch 23 may be connected in series in sequence, or three switches in total of the photoelectric switch 22, the tact switch 23 and the photoelectric switch 22 may be connected in series in any sequence. When all the switches connected in series are triggered, the whole safety switch part is triggered, and the scheme can avoid the risk of false triggering caused by mistaken touching or failure of a single switch.
More specifically, the control module may be implemented in various forms, for example, the control module includes an MOS transistor, a source and a drain of the MOS transistor are respectively connected to the power supply module and the relay portion, and the serial photoelectric switch 22 and the tact switch 23 have one end connected to the power supply module and the other end connected to a gate of the MOS transistor, and are configured to enable the source and the drain of the MOS transistor to be conducted when the serial photoelectric switch 22 and the tact switch 23 are triggered.
The control module adopts an MOS tube to control the power supply of the relay, when the photoelectric switch 22 and the tact switch 23 which are connected in series are triggered, the source and the drain of the MOS tube are conducted, the relay part is powered and attracted, the input end of the controller is further connected with the plug, and the energy storage power supply supplies power to the commercial power socket. Those skilled in the art should know that the wiring method of the P-type MOS transistor and the N-type MOS transistor is slightly different, but both the P-type MOS transistor and the N-type MOS transistor can control the on/off of the source and the drain based on the gate to realize the function of controlling the action of the relay.
For another example, the control module may use a triode to control the power supply of the relay, so as to connect the input end of the controller with the plug, and the principle is similar to the foregoing principle.
For another example, the control module may adopt a single chip microcomputer and a switching tube to implement functions, for example, after a trigger signal of the safety switch portion is sent to the single chip microcomputer, the single chip microcomputer controls the switching tube to be conducted, and further, a power supply path of the relay is conducted.
The safety switch part is arranged on the surface of the plug 2 facing the socket, and is triggered when the plug 2 is inserted into the socket.
In order to improve the safety, the safety switch part is arranged as reasonably as possible, such as the following embodiments:
the plug 2 is a three-pin plug, the safety switch part comprises two photoelectric switches 22 and a light touch switch 23, and the photoelectric switches 22 and the light touch switch 23 are sequentially connected in series in any order;
the two photoelectric switches 22 and the light-touch switch 23 are arranged on the surface of the plug 2 facing the socket in a triangular mode, the two photoelectric switches 22 are distributed on two sides of a grounding pin of the three-pin plug, and a live pin and a neutral pin of the three-pin plug are located between the grounding pin and the light-touch switch 23.
As shown in fig. 1 and 2, the safety switch part is formed by connecting three switches in series, the three switches can be connected in series in any sequencing mode, and only when the three switches are triggered simultaneously, the energy storage power supply can energize the plug.
The three switches are arranged around the plug pin 21 in a triangular point position, and only when the plug is correctly inserted into the socket in the opposite direction, all the switches can be triggered simultaneously, so that the safety can be improved.
