Second embodiment

The child safety socket 200 according to the embodiment of the present application has the same implementation principle and technical effects as those of the embodiment, and for brevity, reference may be made to the corresponding contents of the first embodiment.

As shown in fig. 7 to 10, the cambered surface fastener of the child safety socket 200 provided in the present embodiment is a ball 221, a baffle ring 223 is disposed between the spring 222 and the ball 221, and the projection of the slot 212 on the surface of the socket body 210 provided with the jack 218 is circular. The size of the spring 222 should be matched with the size of the socket 212, that is, the diameter of the spring 222 is the same as or slightly smaller than the external inner diameter of the circular arc wall 215 of the socket 212, so that the spring 222 can work stably during the plug-in process of the socket, the middle part of the baffle ring 223 is provided with a through hole 224, and the aperture of the through hole 224 is larger than or equal to the diameter of the pin 12 and smaller than the diameter of the ball 221.

The child safety socket 200 can be provided with a plurality of jack groups 217, each jack group 217 is correspondingly provided with a jack shielding mechanism 250, when one or more jack groups 217 in the child safety socket 200 are not used, the corresponding flexible shielding piece 252 is pushed to the front 211 to completely cover the unused jack groups 217, so that the jacks 218 are prevented from being exposed, and safety accidents caused by inserting conductive objects or fingers into the jacks 218 due to curiosity of children are avoided.

Preferably, in order to further prevent the child from pushing the flexible shielding sheet 252, rough treatment is performed on two ends of the flexible shielding sheet 252 disposed in the second sliding groove 251 or on the inner wall of the second sliding groove 251, so as to increase friction between the flexible shielding sheet 252 and the second sliding groove 251, so that the difficulty of pushing the flexible shielding sheet 252 is increased.

Further, the flexible shutter piece 252 is provided with a plurality of protrusions 253 on the outside of one end of the front face 111 of the socket body 210, which facilitate pushing of the flexible shutter piece 252.

When the flexible shielding sheet 252 needs to be pushed, the thumb of a person presses on the protrusions 253, friction between the fingers of the person and the flexible shielding sheet 252 can be increased, and the flexible shielding sheet 252 can be pushed conveniently.
