It is an electrical product that is used more frequently in people's production and life. The socket is a connector used to connect the device to be charged and the power source. There are various types of existing sockets, and their application occasions are also extremely wide. At present, the socket is generally covered with a waterproof cover for waterproofing. However, if the socket is exposed to the outdoors, when it encounters rain, the waterproof use of the waterproof cover alone is not enough to easily lead to a low waterproof safety factor of the socket. The safety of ordinary sockets is very poor, especially after water ingress and when children accidentally touch it, there are great safety hazards. The waterproof structure of the existing socket cannot achieve a good waterproof effect, and the waterproof structure is easy to fall off and degrade, which makes it difficult to meet people's higher demands for electrical monitoring and electrical safety. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Embodiment 1:

[0029] like Figure 1-Figure 6 As shown, the present invention discloses a two-hole electrical connector, comprising a shell 1, two protective devices 2 are arranged on the side of the shell 1, a closed protective cavity is formed in the protective device 2, and a switching mechanism is arranged in each protective cavity; two unconnected slots are arranged in the shell 1, a trigger mechanism is arranged in each slot, and the switching mechanism is dynamically connected to the trigger mechanism in a one-to-one correspondence; the switching mechanism is electrically connected to another slot other than the slot where the trigger mechanism corresponding to it is located through a conductive device, the conductive device includes a staggered conductor 8, the slot includes a live slot and a neutral slot, the switching mechanism corresponding to the live slot is electrically connected to the neutral slot through the staggered conductor 8, and the switching mechanism corresponding to the neutral slot is electrically connected to the live slot through the staggered conductor 8.

[0030] An isolation protector 6 is provided between the protection cavity and the insertion bin, and the isolation protector 6 is a flexible sealing body; the trigger mechanism transmits the force between the isolation protector 6 and the on-off mechanism. The on-off mechanism includes a fixed conductive sheet 7 and an elastic conductive sheet 5, and the fixed conductive sheet 7 or the elastic conductive sheet 5 is connected to the power supply end through a conductor, and the fixed conductive sheet 7 and the elastic conductive sheet 5 that are not connected to the power supply end are electrically connected to the insertion bin through a conductor.

[0031] The trigger mechanism is triggered by the live and neutral pins. The trigger mechanism includes a slideway arranged in the insertion compartment, and the trigger mechanism includes a driver 4, which is arranged in the slideway. The driver 4 can slide along the slideway, and when the driver 4 slides, it can drive the elastic conductive sheet 5 and the fixed conductive sheet 7 to contact each other through the isolation protector 6. The driver 4 is provided with an inclined pushing surface, and the angle between the pushing surface and the insertion direction of the pin is an acute angle.

[0032] A conductive contact piece 9 is provided in the insertion compartment, and the fixed conductive piece 7 or the elastic conductive piece 5 is electrically connected to the conductive contact piece 9 through a conductor. A reset device is provided between the driver 4 and the compartment wall of the insertion compartment, and the driver 4 is reset by the elastic force of the reset device or the elastic conductive piece 5. A socket 3 is provided on the housing 1, and a socket protection device 10 is provided on the side wall of the socket 3, and the socket protection device 10 is used to seal the gap between the pin and the socket 3.

[0033] In the specific movement process, when not in use, the fixed conductive sheet 7 and the conductive contact sheet 9 are separated from each other, and the conductive contact sheet 9 in the insertion compartment is not charged.

[0034] When in use, the plug is inserted into the insertion compartment, and the live wire plug contacts the live wire conductive contact piece 9. The live wire plug drives the driver 4 to slide through the push surface. The driver 4 pushes the isolation protector 6 to move, and the isolation protector 6 pushes the elastic conductive sheet 5 and the fixed conductive sheet 7 to contact each other, and the ground electrode of the power supply is transferred to the conductive contact piece 9 of the ground wire through the fixed conductive sheet 7, the elastic conductive sheet 5, and the staggered conductor 8 to achieve conduction.

By adopting a sealing protection mechanism, the risk of socket leakage can be reduced; by fixing the sealing mechanism between the connector body and the conductive isolation mechanism, while ensuring the sealing, the service life of the seal can be increased and its reliability can be improved.

[0040] An isolation protector 6 is provided between the protection cavity and the insertion bin. The isolation protector 6 is a flexible sealing body, preferably made of silicone material. The trigger mechanism transmits the force between the isolation protector 6 and the on-off mechanism and provides a certain restoring force. The on-off mechanism includes a fixed conductive sheet 7 and an elastic conductive sheet 5. The fixed conductive sheet 7 or the elastic conductive sheet 5 is connected to the power supply end through a conductor. The fixed conductive sheet 7 or the elastic conductive sheet 5 that is not connected to the power supply end is electrically connected to the insertion bin through a conductor.

[0041] The trigger mechanism is triggered by the live and neutral pins. The trigger mechanism includes a slideway arranged in the insertion compartment, and the trigger mechanism includes a driver 4, which is arranged in the slideway. The driver 4 can slide along the slideway, and when the driver 4 slides, it can drive the elastic conductive sheet 5 and the fixed conductive sheet 7 to contact each other through the isolation protector 6. The driver 4 is provided with an inclined pushing surface, and the angle between the pushing surface and the insertion direction of the pin is an acute angle.

The driver 4 pushes the isolation protector 6 to move, and the isolation protector 6 pushes the elastic conductive sheet 5 and the fixed conductive sheet 7 to contact each other, and the ground wire electrode of the power supply is transferred to the ground wire conductive contact piece 9 of the same group through the fixed conductive sheet 7, the elastic conductive sheet 5, and the staggered conductor 8 to achieve conduction.

[0045] At the same time, the ground pin drives the driver 4 to slide through the push surface. The driver 4 pushes the isolation protector 6 to move, and the isolation protector 6 pushes the elastic conductive sheet 5 and the fixed conductive sheet 7 to contact each other, and transmits the live wire electrode of the power supply to the live wire conductive contact sheet 9 of the same group through the fixed conductive sheet 7, the elastic conductive sheet 5, and the staggered conductor 8 to achieve conduction.
