A multifunctional anti-electric shock power converter

Abstract

The multifunctional anti-electric shock power converter of the present invention includes a power strip and an adapter. A preferred method of use is: first insert the electrical appliance plug into the adapter, and then insert the protrusion at the lower end of the adapter into the socket of the power strip. Since the live wire hole, the neutral wire hole, and the ground wire hole are located at the bottom of the socket of the power strip, it is impossible for a person's fingers to touch the circuit during the pin connection process with the adapter, so electric shock can be effectively prevented. At the same time, when the adapter fails, only the adapter needs to be replaced, which has a longer life than a conventional power converter. The upper end of the adapter can be made into a two-hole, three-hole or USB socket, which can be suitable for different usage environments. Furthermore, the power strip is provided with a linkage power connection mechanism. When the adapter is inserted into the socket of the power strip, the circuit is still in a disconnected state. Only after rotating a predetermined angle, the circuit will be connected, thereby effectively preventing people from getting electric shock.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0023] Please see Figures 1 to 9 A multifunctional anti-electric shock power converter includes a power strip 10 and an adapter 20. The power strip 10 is provided with at least one socket with a rectangular cross-section, and the bottom of the socket is provided with a live wire hole, a neutral wire hole, and a ground wire hole. The bottom of the adapter 20 is provided with a boss corresponding to the socket on the power strip 10, and the bottom of the boss is provided with a plurality of pins. The upper surface of the adapter 20 is provided with a socket matching an electrical plug to connect the electrical plug.

[0024] During the wiring process, since the boss and the socket are matched, the hand on the adapter 20 cannot touch the live wire hole at the bottom of the socket of the power strip 10, thus preventing the hand from getting an electric shock when dry. If the hand is wet, when the electrical plug is inserted into the adapter 20, the only exposed part of the wire is the pin part of the adapter 20. Compared with the traditional power strip 10, it is difficult for water to come into contact with the pins, thus preventing the hand from getting an electric shock when wet.

[0025] Embodiment 1, the plug board 10 includes an insulating shell 101, a live copper sheet 102, a neutral copper sheet 103, a ground copper sheet 104, a shunt power controller switch, and a linkage power connection mechanism 106, wherein the live copper sheet 102, the neutral copper sheet 103, the ground copper sheet 104, the shunt power controller switch, and the linkage power connection mechanism 106 are arranged in the insulating shell 101, a plurality of live connectors are connected in parallel on the live copper sheet 102, a plurality of neutral connectors are connected in parallel on the neutral copper sheet 103, and a plurality of ground connectors are connected in parallel on the ground copper sheet 104, the shunt power controller switch is connected to the live copper sheet 102 and the neutral copper sheet 103, the number of the shunt power controller switches is the same as the number of the live connectors or the neutral connectors, and the linkage power connection mechanism 106 includes a rotating bracket 1061, a gear 1062, a rack 1063, and three L-shaped copper columns 1064, a rotating bracket The bracket 1061 is mounted on the insulating shell 101, and the upper end surface of the rotating bracket 1061 is the bottom of the socket of the socket board 10. The upper end surface of the rotating bracket 1061 is provided with a live wire hole, a neutral wire hole, and a ground wire hole. The gear 1062 is sleeved and connected to the rotating bracket 1061, and the rack 1063 is meshed and connected with the gear 1062. One end of the rack 1063 is adjacent to the shunt power controller switch and is provided with a protrusion to control the operation of the shunt power controller switch by sliding the rack 1063. The lower end of the rotating bracket 1061 is also fixedly connected to three L-shaped copper columns 1064, and the upper ends of the three L-shaped copper columns are respectively connected to the live wire hole, the neutral wire hole, and the ground wire hole. When the rotating bracket 1061 rotates a predetermined angle, the three L-shaped copper columns are connected to the corresponding live wire connector, the neutral wire connector, and the ground wire connector, and the rack 1063 slides and controls the shunt power controller switch to close.

[0026] Children are very curious. Some children may insert conductive filaments into the through holes of the power strip 10. The power strip 10 of the present invention includes a linkage power connection mechanism 106. The circuit is connected only after the adapter 20 drives the linkage power connection mechanism 106 to rotate a predetermined angle, thereby preventing children from getting an electric shock through the conductive filaments.

[0027] In embodiment 2, the interior of the insulating shell 101 is provided with a support positioning seat, a rack 1063 guide groove, and a joint insulating groove. The rotating bracket 1061 is mounted on the support positioning seat. A horizontal support positioning groove is provided on the side wall of the support positioning seat. One end of the L-shaped copper column connected to the copper sheet is located in the horizontal support positioning groove. The rack 1063 is located in the rack 1063 guide groove. The live wire connector, the neutral wire connector, and the ground wire connector are located in the joint insulating groove.

[0028] In embodiment 3, the power strip 10 further comprises a magnetic guide plate 107 to guide the user to insert the adapter 20 into the power strip 10 . The magnetic guide plate 107 is snap-connected with the upper end of the insulating shell 101 . A through hole matching the socket of the power strip 10 is provided in the middle of the magnetic guide plate 107 .

[0029] In special circumstances such as darkness, it is difficult for people to observe the positions of the sockets of the power strip 10 . The magnetic connection between the power strip 10 and the adapter 20 can effectively guide the user to insert the adapter 20 into the power strip 10 .

[0030] In Example 4, the adapter 20 is spherical, and the boss at the lower end of the adapter 20 includes an adapter 201 and a cube portion 202. The lower end of the adapter 201 is connected to the upper end of the cube portion 202, and pins are provided at the bottom of the cube portion 202. The upper surface of the magnetic guide plate is a concave surface that matches the adapter 20.

[0031] The adapter 20 drives the linkage power connection mechanism 106 to rotate during the rotation process. The linkage power connection mechanism 106 is separated from the magnetic guide plate 107. The magnetic guide plate 107 and the cylindrical portion 201 of the boss of the adapter 20 are at the same position. The adapter 20 does not drive the magnetic guide plate 107 to rotate during the rotation process. After the linkage power connection mechanism 106 rotates to a predetermined position, the copper columns corresponding to the live wire hole, the neutral wire hole, and the ground wire hole are connected to the corresponding connectors. At the same time, under the action of the gear 1062, the rack 1063 triggers the switch of the branch power controller, thereby connecting the line.

[0032] In Embodiment 5, the power strip 10 further includes a voice prompt module 108. When the circuit is connected, the voice prompt module 108 emits a sound for prompting.

[0033] In Example 6, the power strip 10 further includes a main power switch 109 to control the connectivity of the circuit of the power strip 10 .

[0034] At the same time, since the present invention can realize the opening and closing of the circuit in the socket and the connection and disconnection of the current by only rotating, the plug of the frequently used electrical appliances can avoid frequent plugging and unplugging, and the power supply and power off only need to rotate the adapter plugged in the socket forward and reverse by a certain angle. When the electrical appliance needs to be replaced and used in the power supply area, the adapter can be unplugged.

[0035] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
