Technical Field

Background

Power connectors are used in a wide variety of applications, and are used in almost every type of electrical appliance. However, the power connectors used at present are dangerous. When the socket is empty, the socket hole is still electrified, and if a conductive object is inserted by mistake, electric shock or short circuit accidents are easily caused. At present, the state provides that an anti-electric-shock door is required to be installed on a jack of a power socket, so that accidents are avoided, but other defects are brought, such as labor consumption and easy damage of plugging and unplugging plugs, and the anti-electric-shock door can still be opened when a conductive object is plugged into the power socket from two holes at the same time, so that short circuit or electric shock accidents are caused. Moreover, the electric shock prevention door is not damp-proof, short-circuit accidents are still easy to happen due to wetting and water immersion, and electric shock accidents are caused by the fact that fingers touch pins of the plug carelessly when the plug is inserted or pulled by half. Therefore, the method of installing the electric shock preventing door is not a good method.

In view of these problems, some safety connectors have been proposed in recent years, and as disclosed in application No. 201210148779.2, there is provided an electrical leakage preventing method and an electrical leakage preventing connector including two connecting units to be connected, each of the connecting units including a conductor and an insulating unit, and at least one of the connecting units having a switching unit therein, the insulating units of the two connecting units being in contact with each other to form a closed insulating space in which an external conductive medium is isolated from the conductor, the switching unit, and the contact unit inside. Also, for example, application No. 201620764069.6 discloses an electrical connection device with a sealing mechanism, which includes a connection seat with an electrical connection hole, wherein a conductor part is arranged in the connection seat, and the sealing mechanism is arranged in the electrical connection hole to isolate the conductor from the outside of the connection seat; the connecting conductor matched with the connecting seat can push the sealing mechanism to open the connecting hole, so that the connecting conductor is electrically contacted with the conductor part. In both the two patents, the sealing mechanism is arranged, so that water is prevented from entering the connecting seat, the use safety of the connecting seat is ensured, and the connecting seat has the characteristics of strong water resistance, electric leakage prevention and short circuit prevention; however, the above patents have disadvantages that: if a hard conductive object similar to the connecting conductor is inserted into the electric connecting hole, the hard conductive object is opened to cause electric shock accidents; in addition, in an environment with water, the sealing mechanism is difficult to completely remove the external water without electric leakage, and particularly after the sealing mechanism is used for a certain time, the sealing mechanism is easy to touch and leak electricity due to abrasion, aging, deformation and the like of the sealing material.

Also, for example, application No. 201620763779.7 discloses a socket with a relay, which includes a housing, wherein a contact portion, a conductor portion, a relay, and a trigger portion are provided in the housing, and the conductor portion is isolated from the outside of the housing; the relay is connected with contact site and conductor portion respectively and whether control contact site and conductor portion communicate electrically, and the control end of relay is connected and control relay switch action to the trigger part electricity. This patent starts the closed power transmission of relay through a starting part, and when not triggering the starting part, the relay is in normally open state and can not electrically conduct in the jack. However, the disadvantages of this patent are: when no plug is inserted, once another conductive object which is not a plug is inserted into the socket hole, the starting part is started again, and then an electric shock or a short circuit accident occurs.
