Description

Technical Field

[0001] The invention relates to the technical field of chargers, in particular to a novel charger plug. Background Art

[0002] The connectors of general electronic products and the plugs of electrical appliances are called charger plugs. Household AC power plugs and sockets have male connectors with rod-shaped or copper-plate protrusions, which are physically inserted into female connector-type power sockets with slots or recesses. Most existing mobile phone chargers are directly inserted into the USB data cable, and then the pins are inserted into the socket for direct charging.

[0003] For example, a wired charger proposed in announcement number CN207218301U includes a charger body, a support part, a base, and a mobile phone connection piece; the charger body includes a shell, a power interface is provided on the outside of the shell, a first magnet sheet is provided inside the shell, a charging circuit board is provided above the first magnet sheet, a Mylar sheet is provided above the charging circuit board, a plurality of metal probes are provided on the charging circuit board, and the charging circuit board is connected to the power interface, a through hole is provided at the position of the Mylar sheet corresponding to the metal probe, and a suction cup is evenly provided on the outer periphery of the Mylar sheet; a ball head universal joint is provided at one end of the support part, the bottom of the charger body is connected to the ball head universal joint, and the other end of the support part is pivotally connected to one end of the base; the mobile phone connection piece includes a circuit sheet and a charging plug, the charging plug is connected to the circuit sheet, and the mobile phone connection piece is attached to the surface of the charging circuit board through the circuit sheet and is electrically connected to the metal probe.

[0009] A second spring is fixedly connected to the bottom end of the other mounting block, one end of the second spring is fixedly connected to the first permanent magnet, one end of the first permanent magnet passes through the limiting hole, the first electromagnet and the first permanent magnet are located in the same vertical plane, one end of the second rack plate is fixedly connected to a connecting plate, one end of the connecting plate passes through the first cavity and extends to the inside of the second slot body, one end of the connecting plate is fixedly connected to a top plate on the side wall, the top plate side wall is fixedly connected to a connecting block, and the connecting block is fixedly connected to the side wall of the rubber protective sleeve.

[0013] Furthermore, a glass plate is fixedly connected to the inner wall of the frame, and the sliding sleeve is threadedly connected to the side wall of the threaded rod.

[0014] Furthermore, one end of the threaded rod is fixedly connected to a warning plate, and the warning plate is a cross-shaped structure.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By setting a pop-up component and electrically connecting the first electromagnet to the circuit board, when the data line is unplugged or a short circuit occurs in the circuit, the current passing through the charger plug will decrease, thereby weakening the magnetism of the first electromagnet and the magnetic attraction to the first permanent magnet. Under the elastic action of the second spring, the first permanent magnet is pulled to move upward and leave the limiting hole, releasing the limiting position of the first rack plate, thereby resetting under the elastic action of the first spring, driving the first rack plate to move rightward, and utilizing the meshing relationship between the rack plate and the cylindrical gear to enable the second rack plate to drive the top plate to pop out from the inside of the shell, thereby popping the charger plug off the socket, and in the process of the top plate popping out, the rubber protective cover is driven to unfold and cover the pin to prevent the pin from contacting the ground and causing damage due to collision.

When the charger plug is short-circuited, it automatically pops out at the first time to avoid being on the socket after the short circuit and causing a fire, thereby improving the safety effect.

[0017] By setting the auxiliary components and the warning components, if the charger plug has been short-circuited and burned, but the appearance has not been seriously burned, it is impossible to distinguish whether the charging plug is in a normal state only from the appearance, and there are safety hazards if it is used directly; at the moment of short circuit, when the surge current passes through the second electromagnet, the electromagnetic force of the second electromagnet will suddenly increase sharply, pushing the second permanent magnet to move down a distance suddenly, and this distance allows the slide to push the wedge block into the installation groove and move to the bottom of the wedge block, releasing the limit of the wedge block on the slide, and then reset under the elastic action of the third spring, pushing the slide to move toward the circuit board. During the movement process, the air between the circuit board and the slide is driven into the first slot body along the connecting cavity by the pressure in the second cavity. These gases increase the pressure between the sliding sleeve and the first slot, thereby pushing the sliding sleeve to move outward, and using the threaded relationship between the sliding sleeve and the threaded rod, the threaded rod and the warning plate are rotated forty-five degrees, thereby warning that the charger plug has been short-circuited and damaged and can no longer be used, thereby improving the recognition of the use of the charger plug.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to solve the technical problem that if the charger plug is left plugged in for a long time, it will not only waste electricity, but also continue to heat up, accelerate the aging of the charger, and seriously cause short circuit or high voltage breakdown, causing fire, and there are safety hazards, such as Figure 1 - Figure 7 As shown, the following preferred technical solutions are provided:

[0033] A novel charger plug comprises a shell 1, wherein a pin 2 is symmetrically fixedly connected to the side of the shell 1, a circuit board 21 is symmetrically fixedly installed inside the shell 1, and first cavities 11 are symmetrically opened on the side walls of the shell 1, and a pop-up assembly 3 is fixedly installed inside each first cavity 11. By setting the pop-up assembly 3 and the first electromagnet 313 being electrically connected to the circuit board 21, when the data line is unplugged or the circuit is short-circuited, the current passing through the charger plug will decrease, so that the magnetism of the first electromagnet 313 is weakened, and the magnetic attraction to the first permanent magnet 311 is weakened. Under the elastic action of the second spring 310, the first permanent magnet 311 is pulled upward and leaves the limiting hole 312, thereby releasing the limiting of the first rack plate 32, thereby 4 is reset under the elastic action, driving the first rack plate 32 to move rightward, and utilizing the meshing relationship between the rack plate and the cylindrical gear 31, the second rack plate 33 drives the top plate 36 to pop out from the inside of the shell 1, thereby popping the charger plug off the socket, and in the process of the top plate 36 popping out, the rubber protective cover 37 is driven to unfold and cover the pin 2 to prevent the pin 2 from contacting with the ground and causing damage by bumping. After charging is completed, when the data cable is unplugged, the charger plug automatically pops off from the socket, slowing down the aging of the charger and extending the service life. When the charger plug is short-circuited, it automatically pops out at the first time to avoid it still being on the socket after the short circuit and causing a fire, thereby improving the safety effect. The top wall and the bottom wall of the shell 1 are symmetrically provided with a second cavity 12.

[0034] An auxiliary component 4 is fixedly installed inside each second cavity 12. By setting the auxiliary component 4, the current short-circuit characteristic of the charger plug is utilized: at the moment of short circuit, the current in the circuit will increase sharply. This increased current is several times or even dozens of times that of the normal current, and the short circuit time will last for about one second. During this one second, when the surge of current passes through the second electromagnet 43, the electromagnetic force of the second electromagnet 43 will suddenly increase sharply, thereby pushing the second permanent magnet 44 to move downward a certain distance. This distance allows the slide plate 42 to push the wedge block 46 into the mounting groove 16 and move to the bottom of the wedge block 46, releasing the wedge block 46 from limiting the slide plate 42, and then resetting under the elastic action of the third spring 41, pushing the slide plate 42 to move toward the circuit board 21, and utilizing the pressure difference generated by the sealed sliding of the slide plate 42 and the second cavity 12 to squeeze the gas inside the second cavity 12, so as to drive the warning component 5.

[0035] A warning component 5 is fixedly installed inside each first slot body 13. By setting the warning component 5, if the charger plug has a short circuit, with the cooperation of the auxiliary component 4, the air between the circuit board 21 and the slide plate 42 is introduced into the first slot body 13 along the connecting cavity 15. These gases will increase the pressure between the sleeve 52 and the first slot body 13, thereby pushing the sleeve 52 to move outward. By utilizing the threaded relationship between the sleeve 52 and the threaded rod 51, the threaded rod 51 and the warning plate 53 are rotated forty-five degrees, thereby warning that the charger plug has a short circuit and is damaged and cannot be used anymore, thereby improving the recognition of the charger plug usage.

[0036] The pop-up assembly 3 includes a cylindrical gear 31, which is rotatably connected to the inside of the first cavity 11. The side wall of the shell 1 is symmetrically provided with a second groove 14, each of which is an inverted convex structure. The inner wall of each second groove 14 is fixedly connected with a rubber protective sleeve 37. The inner wall of the first cavity 11 is symmetrically and slidingly connected with the first rack plate 32 and the second rack plate 33 along the diagonal. The inner wall of the first cavity 11 is symmetrically and fixedly connected with a mounting block 39. The inner wall of the first cavity 11 is fixedly connected with a first spring 34, one end of the first spring 34 is fixedly connected to the side wall of the first rack plate 32, the first rack plate 32 and the second rack plate 33 are both meshed with the cylindrical gear 31, and a limiting hole 312 is provided at the top of the first rack plate 32, and a first electromagnet 313 is fixedly connected to the top of one of the mounting blocks 39, and the first electromagnet 313 is electrically connected to the circuit board 21.

[0037] A second spring 310 is fixedly connected to the bottom end of another mounting block 39, and one end of the second spring 310 is fixedly connected to the first permanent magnet 311, and one end of the first permanent magnet 311 passes through the limiting hole 312. The first rack plate 32 is long enough so that the first permanent magnet 311 is always located at the top of the first rack plate 32, the first electromagnet 313 and the first permanent magnet 311 are located in the same vertical plane, and the magnetism of the adjacent end faces of the first electromagnet 313 and the first permanent magnet 311 are opposite, and one end of the second rack plate 33 is fixedly connected to a connecting plate 35, and one end of the connecting plate 35 passes through the first cavity 11 and extends to the inside of the second slot body 14, and one end of the connecting plate 35 is fixedly connected to the top plate 36 on the side wall, and the top plate 36 is fixedly connected to the connecting block 38 on the side wall, and the connecting block 38 and the side wall of the rubber protective sleeve 37 are fixedly connected.

[0038] In this solution: when charging, connect one end of the data cable to the electronic device, and insert the other end into the charger plug, then insert the pin 2 into the socket, and the charger plug is powered on. At this time, the first electromagnet 313 is powered on to generate magnetism, and the first permanent magnet 311 is attracted. At this time, the second spring 310 is in a stretched state, and the elastic force of the second spring 310 is less than the magnetic attraction between the first electromagnet 313 and the first permanent magnet 311, but the second spring 310 is greater than the gravity of the first permanent magnet 311. As the pin 2 continues to enter the socket, the two top plates 36 will be pushed to move into the first cavity 11. At this time, the second rack plate 33 moves synchronously, and the meshing relationship between the rack plate and the cylindrical gear 31 is used to make the first rack plate 32 move in the opposite direction and compress the first spring 34, wherein the elastic force of the first spring 34 is less than the force of the pin 2 inserted into the socket. As the first rack plate 32 continues to move, the first permanent magnet 311 is inserted into the limiting hole 312 to stably limit the first rack plate 32;

[0039] The first electromagnet 313 is electrically connected to the circuit board 21. When the data line is unplugged or a short circuit occurs in the circuit, the current passing through the charger plug will decrease, thereby weakening the magnetism of the first electromagnet 313 and weakening the magnetic attraction to the first permanent magnet 311. Under the elastic action of the second spring 310, the first permanent magnet 311 is pulled upward and leaves the limiting hole 312, thereby releasing the limiting position of the first rack plate 32, thereby resetting under the elastic action of the first spring 34, driving the first rack plate 32 to move rightward, and utilizing the meshing relationship between the rack plate and the cylindrical gear 31. , so that the second rack plate 33 drives the top plate 36 to pop out from the inside of the shell 1, thereby popping the charger plug off the socket, and in the process of the top plate 36 popping out, the rubber protective cover 37 is driven to unfold and cover the pin 2 to prevent the pin 2 from contacting the ground and causing damage by bumping. After charging is completed, when the data cable is unplugged, the charger plug automatically pops off from the socket, slowing down the aging of the charger and extending the service life. When the charger plug is short-circuited, it will automatically pop out at the first time to avoid it still being in the socket after a short circuit and causing a fire, thereby improving the safety effect.

[0040] In order to solve the technical problem that after charging is completed or after a short circuit, the charger plug will pop out of the socket, but it is not clear whether it is normal and intact, or has been short-circuited and burned, so there is a lack of warning devices to identify the condition of the charger plug, such as Figure 8 - Fig.12 As shown, the following preferred technical solutions are provided:

[0041] The auxiliary component 4 includes multiple third springs 41, each of which is fixedly connected to the inner wall of the second cavity 12. The side walls of the second cavity 12 are symmetrically provided with mounting grooves 16. The top wall of the second cavity 12 is fixedly connected with a second electromagnet 43, and the second electromagnet 43 is electrically connected to the adjacent circuit board 21.

[0042] A plurality of third springs 41 are commonly and fixedly connected with a slide plate 42, and the slide plate 42 is sealingly and slidingly connected with the inner wall of the second cavity 12, and the side wall of the slide plate 42 is an inclined surface, and each inner wall of the mounting groove 16 is fixedly connected with a fourth spring 45, and one end of the fourth spring 45 is fixedly connected with a wedge block 46, and each wedge block 46 is slidably connected to the inside of the mounting groove 16, and each wedge block 46 is in contact with the inclined surface of the slide plate 42, and a second permanent magnet 44 is fixedly connected with the top of the slide plate 42.

[0043] The warning component 5 includes a threaded rod 51 , which is rotatably connected to the inner wall of the first slot body 13 , a sleeve 52 is sealingly and slidably connected to the inner wall of the first slot body 13 , and a frame 54 is fixedly connected to the side wall of the first slot body 13 .

[0044] A glass plate is fixedly connected to the inner wall of the frame 54 to prevent it from contacting the warning plate 53 and causing the warning plate 53 to move and affect the warning effect. The sliding sleeve 52 is threadedly connected to the side wall of the threaded rod 51. One end of the threaded rod 51 is fixedly connected to the warning plate 53. The warning plate 53 is a cross-shaped structure.

[0045] In this solution: if a short circuit has occurred after the charger plug is ejected from the socket, the current short circuit characteristic of the charger plug is utilized: at the moment of short circuit, the current in the circuit will increase sharply, and this increased current is several times or even dozens of times that of normal current, and the short circuit will last for about one second. During this one second, when the surge of current passes through the second electromagnet 43, the electromagnetic force of the second electromagnet 43 will suddenly increase sharply, thereby pushing the second permanent magnet 44 to move downward a certain distance. This distance allows the slide plate 42 to push the wedge block 46, compressing the fourth spring 45 into the mounting groove 16, and moving it to the bottom of the wedge block 46, releasing the limit of the wedge block 46 on the slide plate 42, wherein the elastic force of the plurality of fourth springs 45 is greater than the sum of the electromagnetic force between the second electromagnet 43 and the second permanent magnet 44 and the elastic force of the third spring 41 when the current is normal, and is less than the sum of the electromagnetic force between the second electromagnet 43 and the second permanent magnet 44 and the elastic force of the third spring 41 when the short circuit occurs. 44 and the elastic force of the third spring 41, and then reset under the elastic action of the third spring 41, pushing the slide plate 42 to move toward the circuit board 21, wherein after the limit of the wedge block 46 is released, the elastic force of the third spring 41 is greater than the pressure between the slide plate 42 and the circuit board 21. During the movement, if the charger plug has been short-circuited, the pressure difference generated by the sealed sliding of the slide plate 42 and the second cavity 12 is utilized to draw the air between the circuit board 21 and the slide plate 42 along the connecting cavity 15 into the first slot body 13. These gases will increase the pressure between the sleeve 52 and the first slot body 13, thereby pushing the sleeve 52 to move outward, and utilizing the threaded relationship between the sleeve 52 and the threaded rod 51, the threaded rod 51 and the warning plate 53 are rotated forty-five degrees, thereby warning that the charger plug has been short-circuited and is damaged and cannot be used any more, thereby improving the recognition of the charger plug usage.
