Embodiment Construction
[0025] Below in conjunction with accompanying drawing, the present invention will be further described.
[0026] figure 1 It is a structural schematic diagram of an embodiment of the electric shock-proof power plug of the present invention. figure 2 It is a schematic diagram of the internal structure of the insulating seat 10 of an embodiment of the electric shock-proof power plug of the present invention. like figure 1 and figure 2 As shown, the waterproof power plug includes an insulating base 10 and several pins 50 located at the front end of the insulating base 10 , and also includes an insulating sheath 20 , a connecting cable 30 and a gear assembly 40 . When the sheath 20 moves close to the insulating seat 10, the sheath 20 is driven by the gear set so that the pin 50 moves in the sheath 20 in a direction away from the insulating seat 10 and from The sheath 20 protrudes inside.
[0027] A connection channel 11 is disposed in the insulating base 10 , the connecting...

The invention relates to an electric-shock preventive power supply plug. The electric-shock preventive power supply plug comprises an insulation seat and a plurality of pins arranged on the front endof the insulation seat, and also comprises an insulation jacket, a connecting cable and a gear assembly, the end portion of each pin and the end portion of the jacket are respectively connected with the gear assembly, and when the jacket moves to the insulation seat, the jacket is driven by virtue of the gear group, so that the pins move in a direction, away from the insulation seat, in the jacketand stretches out of the jacket. When the electric-shock preventive power supply plug is in use, and when the jacket squeezes a connector in a socket, the pins are squeezed by the jacket and driven by the gear assembly to move outwards so as to stretch out of the jacket to be connected with the connector of the socket, so that a switch-on function between the power supply plug and the socket canbe realized; and moreover, when the plug is connected with the socket, other portions of the pins are still located in the jacket, so that the contact electric conduction of the pins can be prevented,and the safety performance of the power supply plug can be improved.
Description
technical field [0001] The invention belongs to the field of connectors, and specifically discloses an electric shock-proof power plug. Background technique [0002] Power plugs are used in various fields. The general power plug can be used as long as it is connected to the power cord. According to the different uses of the power plug, the power cord plug can be used at 250V, 125V, 36V voltage, and can be used at 16A, 13A, 10A, etc. depending on the current. 5A, 2.5A. [0003] The power plug in the prior art includes an insulating base, a metal pin and a transmission cable, the metal pin is arranged on the insulating base, and a welding foot electrically connected with the metal pin is provided on the insulating base, and one end of the transmission cable is welded to the The feet are soldered. The power plug of this structure is easy to leak electricity, and the prongs are easily exposed when inserted into the socket, and the safety is low. Contents of the invention ...
