Referring to fig. 2, the trigger switch 4 includes a conductive plate 5 and a conductive elastic element 6 fixed at the bottom of the socket board, wherein the conductive plate 5 is connected to a terminal on the socket, but not the conductive contact plate 3 is connected to a terminal on the socket, as shown in fig. 3, when the socket is powered on, if the conductive plate 5 is connected to a live wire terminal 10 on the socket, the conductive plate 5 is in a charged state, and the conductive contact plate 3 is in an uncharged state, and if the conductive plate 5 is connected to a ground wire terminal 11 on the socket, the conductive plate 5 and the conductive contact plate do not form a loop when the plug terminal of the plug is not inserted into the jack, i.e., are in an open circuit state. The conductive elastic element 6 is placed at the bottom of the socket board, the conductive elastic element 6 has a contact terminal 7 and an elastic metal sheet 8 connected with the contact terminal 7, the contact terminal 7 and the elastic metal sheet 8 may be an integrally formed structure, and may also be connected by welding, which is not limited in this embodiment. As shown in fig. 4, when the jack terminal 12 of the plug is not inserted into the jack 2 or when the jack terminal 12 of the plug is not almost completely inserted into the jack 2, the conductive elastic member 6 is disconnected from the conductive plate 5. When the plug terminal 12 of the plug is inserted into the jack 2, the plug terminal 12 presses the elastic metal piece 8 of the conductive elastic element 6 through the contact terminal 7 so that the elastic metal piece 8 of the conductive elastic element 6 extends left and right to connect the conductive pieces 5. The contact terminals 7 in this embodiment are preferably made of a relatively hard material, such as iron, and the resilient metal sheet 8 is preferably made of a relatively soft material, such as copper.
In the anti-electric shock socket in the embodiment, when the plug terminal of the plug is not inserted into the jack 2 of the socket, the conductive contact piece 3 is not electrified, and when the plug terminal of the plug is slowly inserted into the jack 2, under the action of an external force, the plug terminal 12 of the plug contacts the contact terminal 7 of the conductive elastic element 6, and the elastic metal sheet 8 of the conductive elastic element 6 is pressed through the contact terminal 7, so that the elastic metal sheet 8 of the conductive elastic element 6 extends leftwards and rightwards to be connected with the conductive piece 5, and at the moment, the conductive piece 5, the conductive elastic element 6, the conductive contact piece 3 and the plug form a path, so that the smoothness of a circuit is ensured; when the plug is pulled out, the conductive elastic element 6 will be restored to the original shape under the elastic force of the elastic metal sheet 8 itself, that is, the conductive elastic element 6 will be disconnected from the conductive sheet 5, thereby breaking the circuit, so that the conductive contact piece 3 is not electrified, thereby preventing electric shock.
Preferably, as an implementation manner, the conductive sheets are disposed on one side of the conductive elastic element, that is, the conductive sheets 5 are disposed on the left side or the right side of the conductive elastic element 6, it is understood that the conductive sheets 5 may also be disposed on the left side and the right side of the conductive elastic element 6, wherein when the conductive sheets are disposed on the left side and the right side of the conductive elastic element 6, the connection terminal on the socket is connected to any one of the conductive sheets 5 on the left side and the right side, that is, the connection terminal may be connected to the conductive sheet 5 disposed on the left side of the conductive elastic element 6, or may be connected to the conductive sheet 5 disposed on the right side of the conductive elastic.
Preferably, as an embodiment of the present invention, the bottom of the conductive contact piece 3 has a through hole 9, and the contact terminal 7 of the conductive elastic element 6 passes through the through hole 9, that is, the contact terminal 7 can move up and down in the through hole 9 under the action of external force. In this embodiment, the contact terminal 7 of the conductive elastic member 6 can be easily brought into contact with the jack terminal 12 of the plug by providing the through hole 9 in the bottom of the conductive contact piece 3.
Preferably, as an embodiment of the present invention, the contact terminal 7 has a T-shaped structure, and the contact terminal 7 having the T-shaped structure in the embodiment can increase the contact area between the plug terminal 12 of the plug and the contact terminal 7, so that the plug terminal 12 of the plug can easily contact with the contact terminal 7 when being inserted into the jack 2.
Preferably, as an embodiment of the present invention, the elastic metal sheet 8 of the conductive elastic element 6 has an inverted U-shaped or inverted V-shaped structure, and the elastic metal sheet 8 having the inverted U-shaped or inverted V-shaped structure can make the elastic metal sheet 8 easily extend to the left and right to connect the conductive sheet 5 when an external force is applied, and can automatically recover its original shape under its own elastic force when the external force disappears. It will be appreciated that the resilient metal sheet 8 may also be of other inverted U-like or V-like configuration.
Preferably, as another possible implementation manner of the present invention, the trigger switch 4 is only disposed in the live wire jack of the electric shock prevention socket, and of course, the trigger switch 4 may also be disposed in the live wire and neutral wire jacks of the electric shock prevention socket. Work as when trigger switch 4 only sets up in the live wire jack, then when will preventing electric shock socket and power cord connection, need distinguish the live wire and the zero line of power cord earlier, then correspond the binding post that links to each other with the live wire jack of this electric shock socket with the live wire of power cord and be connected, however, work as trigger switch 4 set up in when preventing electric shock socket's live wire and zero line jack, then need not distinguish the live wire and the zero line of power cord for this use of preventing electric shock socket is more convenient.
According to the electric shock prevention socket provided by the invention, the trigger switch is arranged below the conductive contact piece in the jack of the existing socket, so that the conductive contact piece is not electrified when no plug terminal of a plug is inserted into the jack or the plug terminal of the plug is almost completely connected into the jack, and therefore, a user is prevented from touching the conductive contact piece to get an electric shock.
