Because the rotation direction of the eccentric wheel is transited from the long radius direction to the short radius direction, the restoring force and the friction force provided by the eccentric wheel are very small in the sliding-in stage of the rear section in the inserting process of the inserting piece, so that the inserting is very easy in the inserting stage; when the inserted sheet is inserted into the gap through the socket of the shell, the rotation of the eccentric wheel drives the rotation of the switch shifting sheet, so that the switch sheet of the switch shifting sheet is close to the wiring terminal, and after the switch shifting sheet rotates to a certain angle, the switch sheet of the switch shifting sheet is contacted with the wiring terminal, so that the circuit is conducted. When the insert is pulled out, the eccentric wheel is provided with a tendency of rotating towards the direction of the substrate under the action of the friction force between the insert and the eccentric wheel, and the contact part of the eccentric wheel and the insert is transited from a short radius to a long radius in the rotating direction, and the rotation in the rotating direction provides larger pressing force for the insert due to the change of the radius, so that larger friction force is provided for the insert. Therefore, when the plug-in connector is pulled out, the locking force of the eccentric wheel to the plug-in connector is larger than the insertion force when the plug-in connector is inserted.

Example 3

The utility model provides a socket that embodiment 3 provided is basically the same as embodiment 2, and its difference lies in, is provided with first reset spring 34 on eccentric wheel 3; the first return spring 34 is connected to the eccentric wheel 3 at one end and to the rotating shaft 7 at the other end (the connection to the housing, the base, or the base plate may be any, as appropriate). A limiting groove 33 is formed in one side, away from the socket, of the eccentric wheel 3, a shaft hole 41 matched with the rotating shaft 7 is formed in the switch shifting piece 4, a driving piece 42 is arranged on the switch shifting piece 4, and the driving piece 42 can move in the limiting groove 33 in the circumferential direction; the switch shifting piece 4 is provided with a second reset spring 43, one end of the second reset spring 43 is connected with the switch shifting piece 4, the other end of the second reset spring 43 is connected with the rotating shaft 7 (the second reset spring 43 can be connected with an eccentric wheel, a shell, a base and a substrate according to the situation), and when the second reset spring 43 is in an initial state, the driving piece 42 is positioned at one end, close to the wiring terminal 5, in the limiting groove 33.

In order to achieve the purpose that the switch shifting piece can stably move on the limiting groove, the driving piece is of a U-shaped structure, the thickness of the eccentric wheel is matched with the opening of the U-shaped structure, and the driving piece can be clamped and sleeved on the limiting groove to prevent falling. When the switch driving piece is used, the driving piece of the switch shifting piece is tightly attached to one side, away from the second guide opening, of the eccentric wheel limiting groove by the elastic force provided by the spring element, and the elastic force capable of continuously ensuring the close connection can be provided along with the rotation of the eccentric wheel. Meanwhile, the switch shifting piece can be pushed to move in the direction opposite to the elastic direction under the action of external force, the switch shifting piece can move in the range of the limit groove of the eccentric wheel, and after the action of the external force disappears, the driving piece of the switch shifting piece can return to the state that the front part of the driving piece is in contact with one side of the limit groove of the eccentric wheel. The binding post is directly connected with a power supply lead and is arranged at a fixed position and cannot move. After the direction of keeping away from the socket earlier at eccentric wheel second guide mouth rotates certain angle, the switch plate of switch plectrum can contact with the terminal in the assembly of eccentric wheel and switch plectrum, because the driving plate can move in the spacing inslot, so that the second guide mouth that does not influence the eccentric wheel can continue to rotate certain angle to the direction of keeping away from the socket, simultaneously, under the effect of above-mentioned second reset spring elasticity, the terminal is hugged closely all the time to the switch plate of switch plectrum this moment. After the eccentric wheel is rotated to return, the switch sheet of the switch plectrum can be disconnected with the wiring terminal and returns to the power-off state. When the plug is inserted into the socket along the direction in fig. 5 and the plug is not inserted, the base, the substrate, the eccentric wheel and the switch plectrum are all in a non-powered state because the switch piece of the switch plectrum and the binding post are in a non-contact state. The base, the substrate and a part of the eccentric wheel are exposed in the jack of the socket, and the binding post is buried in the deep part of the base and is in a position which cannot be reached by a user, so that the jack is in a completely safe state; when the plug is inserted, the inserting sheet can be inserted into the first guide opening from the socket, then the inserting sheet is inserted into the gap, after the inserting sheet is inserted to a certain depth, the front end of the inserting sheet can be contacted with the second guide opening of the eccentric wheel, along with the penetration of the inserting sheet, the inserting sheet can push the eccentric wheel to rotate along the rotating shaft on the base, due to the eccentric design of the eccentric wheel and the design of the second guide opening part, after the eccentric wheel rotates for a certain angle, the second guide opening of the eccentric wheel can be separated from the inserting sheet to lose the effect, and the inserting sheet can slide into the gap between the substrate and the eccentric wheel along the outer ring wall of the eccentric wheel. Because the rotation direction of the eccentric wheel is transited from the long radius direction to the short radius direction, the restoring force and the friction force provided by the eccentric wheel are very small in the sliding-in stage of the rear section in the inserting process of the inserting sheet. Therefore, the insertion is easy in the insertion stage. When the inserted sheet is inserted, the rotation of eccentric wheel will drive the rotation of switch plectrum, and lead to the switch piece and the terminal of switch plectrum to be close, when rotating certain angle after, the switch piece of switch plectrum will contact with the terminal to make the circuit switch on. The eccentric wheel continues to rotate, the binding post leads the switch plectrum to move and stop, and at this moment, the position of the driving piece of the switch plectrum in the spacing groove of the eccentric wheel will change, and the switch piece of the switch plectrum keeps in close contact with the binding post under the effect of the second reset spring. When the insert is pulled out, the eccentric wheel is provided with a tendency of rotating towards the direction of the substrate under the action of the friction force between the insert and the eccentric wheel, and the contact part of the eccentric wheel and the insert is transited from a short radius to a long radius in the rotating direction, and the rotation in the rotating direction provides larger pressing force for the insert due to the change of the radius, so that larger friction force is provided for the insert. Therefore, when the plug-in connector is pulled out, the locking force of the eccentric wheel to the plug-in connector is larger than the insertion force when the plug-in connector is inserted. When the base plate or the eccentric wheel is used for a long time and is worn, the eccentric wheel can automatically compensate errors caused by the worn part due to the eccentric design of the eccentric wheel. Because the access point of the live wire is fixed in the socket, the switch function is only required to be provided for the corresponding insertion point of the live wire, the insertion points of the zero wire and the ground wire are accessed, the switch plectrum, the binding post and the corresponding structure can be omitted, and the zero wire and the ground wire can be directly connected with the base or the substrate.
