Description

Technical Field

[0001] The utility model relates to the technical field of switch and socket structures, in particular to a safety switch and socket structure for preventing electric shock. Background Art

[0002] The socket is a device used to provide power to electrical appliances. However, since the socket is basically in a energized state (that is, there is voltage on the live wire), when the socket is not in use, there is still electricity in the circuit inside the socket. When liquid enters the socket, since there is still voltage on the live wire, the circuit inside the socket is short-circuited the moment the liquid enters.

[0003] For example, Chinese patent publication number CN206332227U discloses a water-permeable, moisture-proof, self-springing safety socket, comprising a retaining wall, an insert hole, and a live wire socket. The retaining wall encloses a sealed live wire cavity and a neutral wire cavity. Both the live and neutral wire cavities are provided with drainage outlets. A waterproof insert membrane is placed in the insert hole. The live wire socket includes a live wire connection plate and a live wire slot sleeve, with a gap between the two.

[0004] The safety switch assembly in the aforementioned reference document is located on the bottom surface of the live wire connection plate. The entire socket can only be powered when the plug is fully inserted. At this time, the conductive metal part of the plug will not be exposed outside the socket, effectively preventing the user from contacting it and avoiding electric shock. Secondly, the waterproof insert can effectively prevent water from entering the socket, improving the socket's sealing and safety. When water enters the socket, the water can be quickly drained out through the drain port;

[0005] However, when the above-mentioned switch and socket structure is in use, if a child inserts a finger or a conductive object into one of the sockets of the switch and socket by mistake, an electric shock accident may occur. In this way, when the double holes and triple holes of the switch and socket structure are exposed to the outside, children may be easily accidentally inserted into the sockets and suffer electric shock accidents, and the safety protection is low. Utility Model Content

[0006] The purpose of the utility model is to provide a safety switch and socket structure that prevents electric shock. This switch and socket structure can block and position the sockets to prevent electric shock accidents caused by the wrong insertion of one group of sockets, thereby greatly improving the safety against electric shock.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an anti-electric shock safety switch socket structure, comprising a panel and a rear end cover, wherein a first socket and a second socket are respectively provided on one side of the panel, and a device groove is provided at the junction of the panel and the rear end cover, a fixed block is fixedly installed on one side of the inner wall of the device groove, a positioning plate is nested on the outside of the fixed block, a compression spring is fixedly installed between the positioning plate and the inner wall of the device groove, wedge-shaped platforms are respectively provided on both sides of the outside of the positioning plate, and tooth blocks are integrally formed with equal intervals on the side of the wedge platform close to the inner wall of the second socket, and an insertion rod is fixedly connected to the side of the wedge platform away from the tooth block, and a positioning spring is nested on the insertion rod located on the outside of the positioning plate.

[0008] Preferably, the second insertion hole is provided with a clearance hole on one side close to the device slot, and the two groups of wedge-shaped platforms are respectively located at the edge of one side of the inner wall of the two groups of the clearance holes.

[0009] Preferably, an engagement groove matching the tooth block is provided on the inner wall of the second insertion hole, and the tooth block on one side of the wedge-shaped platform is inserted into the corresponding engagement groove.

[0010] Preferably, an open groove is provided in the middle of one side of the positioning plate, and the open groove on one side of the positioning plate is nested outside the fixing block.

[0011] Preferably, one end of the insertion rod is movably inserted into the inner wall of the positioning plate.

[0012] Preferably, the opening slot and the end of the insertion rod are respectively fitted with the fixing block in a clearance fit, and the positioning plate is fitted with the device slot in a clearance fit.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the present invention, if a child accidentally inserts a finger or a conductive object into one of the groups of sockets on both sides of the first socket or the second socket, the wedge-shaped platform on one side squeezes the positioning spring through the insertion rod and moves closer to the positioning plate, thereby separating the tooth block on the wedge-shaped platform on one side from the bite groove in the socket, while the wedge-shaped platform in the socket on the other side still bites the tooth block into the socket through the bite groove. In this way, the wedge platform in the socket that is accidentally inserted can be moved a certain distance from the clearance hole and then locked in position, thereby preventing the child's inserted finger or conductive object from further entering the accidentally inserted socket and causing an electric shock accident. The switch and socket structure can actively lock one of the groups of sockets on both sides to avoid electric shock caused by accidental insertion, and has a high safety factor.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-4 The utility model provides a technical solution: an anti-electric shock safety switch socket structure, comprising a panel 1 and a rear end cover 2, wherein a first jack 11 and a second jack 12 are respectively provided on one side of the panel 1, and a device slot 3 is provided at the junction of the panel 1 and the rear end cover 2;

[0022] A fixing block 6 is fixedly installed on one side of the inner wall of the device groove 3, and a positioning plate 4 is nested on the outside of the fixing block 6. A compression spring 41 is fixedly installed between the positioning plate 4 and the inner wall of the device groove 3. Wedge-shaped platforms 5 are respectively provided on both sides of the outer side of the positioning plate 4. Tooth blocks 51 are integrally formed at equal intervals on the side of the wedge platform 5 close to the inner wall of the second insertion hole 12. An insertion rod 52 is fixedly connected to the side of the wedge platform 5 away from the tooth block 51. A positioning spring 53 is nested on the insertion rod 52 located on the outside of the positioning plate 4;

[0023] The first socket 11 is a two-hole socket, and the second socket 12 is a three-hole socket, wherein the top of the three-hole socket is grounded, and the two sides of the bottom are neutral and live wiring;

[0024] When a child accidentally inserts his fingers or a conductive object into one of the groups of sockets on both sides of the first socket 11 and the second socket 12, the wedge-shaped platform 5 on one side squeezes the positioning spring 53 through the insertion rod 52 and moves closer to the positioning plate 4, so that the tooth block 51 on the wedge-shaped platform 5 on one side is separated from the bite groove 14 in the socket, while the wedge-shaped platform 5 in the socket on the other side still bites the tooth block 51 into the socket through the bite groove 14. In this way, the wedge-shaped platform 5 in the mistakenly inserted socket can be moved a certain distance from the clearance hole 13 and then locked in position, thereby preventing the child's inserted fingers or conductive objects from further entering the mistakenly inserted socket and causing electric shock accidents. The switch socket structure can actively lock one of the groups of sockets on both sides to avoid electric shock caused by accidental insertion, and has a high safety factor.

[0025] Among them, the second socket 12 is respectively provided with a clearance hole 13 on one side near the device slot 3, and the two groups of wedge-shaped platforms 5 are respectively located at the edge of one side of the inner wall of the two groups of clearance holes 13. The inner wall of the second socket 12 is provided with an engaging groove 14 matching the tooth block 51, and the tooth block 51 on one side of the wedge-shaped platform 5 is inserted into the corresponding engaging groove 14. A child accidentally inserts his fingers or a conductive object into one of the sockets on both sides of the first socket 11 and the second socket 12. The wedge-shaped platform 5 on one side squeezes the positioning spring 53 through the insertion rod 52 and moves closer to the positioning plate 4, so that the tooth block 51 on one side of the wedge-shaped platform 5 is separated from the engaging groove 14 in the socket, while the wedge-shaped platform 5 in the socket on the other side still engages the tooth block 51 in the socket through the engaging groove 14, so that the wedge-shaped platform 5 mistakenly inserted into the socket can be moved a certain distance from the clearance hole 13 and then locked in position.

[0026] Among them, an open groove 42 is opened in the middle of one side of the positioning plate 4, and the open groove 42 on one side of the positioning plate 4 is nested in the outside of the fixed block 6. One end of the insertion rod 52 is movably inserted into the inner wall of the positioning plate 4. The open groove 42 and the end of the insertion rod 52 are respectively fitted with the fixed block 6. There is a gap fit between the positioning plate 4 and the device slot 3. When the two groups of jacks are inserted with sockets at the same time, the two groups of wedge-shaped platforms 5 squeeze the positioning springs 53, so that the two groups of wedge-shaped platforms 5 are released from the corresponding bite grooves 14 and enter the clearance hole 13. The positioning plate 4 as a whole squeezes the compression spring 41 and separates from the nested fixed block 6, so that the socket can be inserted from the jack to the conductive spring sheet of the rear end cover 2 for conduction.

[0027] Working principle: When the switch socket structure is in use, when the two sets of sockets are inserted into the sockets at the same time, the two sets of wedge-shaped platforms 5 squeeze the positioning springs 53, so that the two sets of wedge-shaped platforms 5 are released from the corresponding bite grooves 14 and enter the clearance holes 13. The positioning plate 4 as a whole squeezes the compression spring 41 and separates from the nested fixing block 6, so that the socket can be inserted from the socket to the conductive spring sheet of the rear cover 2 to conduct electricity;

[0028] When a child mistakenly inserts his fingers or a conductive object into one of the two groups of sockets on both sides of the first socket 11 and the second socket 12, the wedge-shaped platform 5 on one side squeezes the positioning spring 53 through the insertion rod 52 and moves closer to the positioning plate 4, so that the tooth block 51 on the wedge-shaped platform 5 on one side is separated from the bite groove 14 in the socket, while the wedge-shaped platform 5 in the socket on the other side still bites the tooth block 51 into the socket through the bite groove 14. In this way, the wedge-shaped platform 5 in the mistakenly inserted socket can be moved a certain distance from the clearance hole 13 and then locked in position, thereby preventing the child's inserted fingers or conductive objects from further entering the mistakenly inserted socket and causing electric shock accidents. The switch socket structure can actively lock one of the two groups of sockets on both sides to avoid electric shock caused by mistaken insertion, and has a high safety factor.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
