First embodiment

As shown in fig. 1 to 6, the present embodiment provides a child-resistant receptacle 100, which includes a receptacle body 110, a front surface 111 of the receptacle body 110 is provided with a jack 118 for inserting a plug pin of a plug, a slot 112 is provided in the receptacle body 110 at a position corresponding to the jack 118, the slot 112 is communicated with the jack 118, an inner wall of the slot 112 is provided with a conductive contact 114, a position of the slot 112 close to the jack 118 is provided with an arc wall 115, a pin locking mechanism 120 is provided in the slot 112, the pin locking mechanism 120 includes a spring 122 and two arc latches having ferromagnetism, a surface of the arc latch contacting the slot 112 is an arc surface, one end of the spring 122 abuts against a slot wall of the slot 112 far from the jack 118, and the other end of the spring 122 abuts against the two arc.

The prongs 12 of the plug 11 for use with the child-resistant socket 100 are provided with two arcuate recesses 13 located opposite one another. Before use, the structure of the child-resistant socket 100 corresponding to the insertion hole 118 is shown in fig. 2, the pin 12 is inserted into the insertion hole 118, the pin 12 passes through between the two arc-shaped clamping pieces during the insertion process, and then is inserted into the spring 122, the arc surface of the arc-shaped clamping piece contacts with the arc wall 115 and moves downwards along the arc wall 115 during the insertion process, the structure of the slot 112 is shown in fig. 3 after the insertion, and the arc-shaped clamping pieces are embedded into the arc-shaped groove 13 after the insertion of the pin 12. At this time, the plug can not be pulled out only by external force because the pin 12 is clamped by the two cambered clamping pieces. Because the arc-shaped clamping piece has ferromagnetism, only one article with ferromagnetism needs to be taken and placed at the position, corresponding to the jack 118, on the back surface of the child safety socket 100, the arc-shaped clamping piece is attracted by utilizing magnetism, so that the arc-shaped clamping piece compresses the spring 122 towards the direction far away from the jack 118, and moves together with the spring 122 towards the direction far away from the jack 118 as shown in fig. 4, in the moving process, the arc-shaped clamping piece is separated from the arc-shaped groove 13, the locking of the plug 12 is released, and the plug 11 can be easily pulled out at the moment.

The arc wall of the present invention is arc-shaped and does not have a flat surface.

Through the arrangement, the plug 11 can be guaranteed to be difficult to be pulled out after being inserted into the child safety socket 100 on the premise of not using strong magnetic articles, and the safety accident caused by the fact that children pull the plug randomly due to curiosity driving can be effectively prevented.

As shown in fig. 5 and 6, fig. 5 is a top view of the slot 112 after the pins 12 are inserted into the slot 112, fig. 6 is a schematic view of a cut-away structure of the slot 112 after the pins 12 are inserted into the slot 112, and neither of fig. 5 and 6 shows the pins 12. Further, in this embodiment, the fastener is a cylinder 121. The projection of the slot 112 on the side of the socket body 110 where the insertion hole 118 is provided is rectangular, the size of the spring 122 matches with the size of the slot 112, and the length direction of the cylinder 121 is parallel to the arc wall 215.

When the specific configuration of the child-resistant receptacle 100 is as described above, the prongs 12 used in cooperation may be in the shape of a cylinder or a substantially rectangular parallelepiped. In the present embodiment, the shape of the insertion hole 118 is rectangular, and the shape of the pin 12 is rectangular parallelepiped. After the pin 12 is inserted into the insertion hole 118 and enters the insertion groove 112, the two cylinders 121 enter the arc-shaped grooves 13 to lock the pin 12, so that the pin 12 cannot be pulled out.

The embodiment also provides a child safety socket and plug set, which comprises a plug 11 and the child safety socket 100 provided by the embodiment, wherein two arc-shaped grooves 13 are arranged on the pins 12 of the plug 11, the positions of the two arc-shaped grooves 13 are opposite, the size of each arc-shaped groove 13 is matched with that of each cylinder 121, and the shape of each arc-shaped groove 13 is matched with the peripheral surface of each cylinder 121.

The plug 11 of this embodiment may be a plug of a connection wire, or may be an empty plug without a connection wire, and when the plug 11 is an empty plug, the plug 11 is inserted into the insertion hole 118, so as to prevent a child from causing a safety accident due to curious insertion of a conductive object or a finger into the insertion hole 118.

Second embodiment

The embodiment of the present invention provides a child safety socket 200, which has the same technical effects as the embodiment, and for the sake of brief description, the embodiment does not refer to the parts, and can refer to the corresponding contents in the first embodiment.

As shown in fig. 7 to 10, the arc-shaped fastener of the child-resistant socket 200 of the present embodiment is a round ball 221, a stop ring 223 is disposed between the spring 222 and the round ball 221, and a projection of the slot 212 on a side of the socket body 210 where the insertion hole 218 is disposed is circular. The size of the spring 222 should match the size of the slot 212, that is, the diameter of the spring 222 is the same as or slightly smaller than the outer diameter of the arc wall 215 of the slot 212, so that the spring 222 can work stably during the plugging and unplugging of the socket, the middle of the baffle ring 223 has a through hole 224, and the diameter of the through hole 224 is larger than or equal to the diameter of the pin 12 and smaller than the diameter of the round ball 221.
