Abstract
Description
Technical Field
[0001] This invention belongs to the field of socket equipment technology, and particularly relates to a smart socket. Background Technology
[0002] With the development of electrification, more and more electrical appliances are being used in daily life, providing services and improving convenience. This has led to the development of electrical outlets to facilitate the supply of power to these appliances. A socket typically provides at least one socket unit, usually a three-hole or two-hole socket unit. Normally, the socket assembly is always connected to power. When an appliance needs power, the user simply inserts the appliance's plug into the socket assembly. In daily life, children lack safety awareness and may touch the socket with their fingers or other objects, or insert their fingers or other objects into the socket holes, potentially causing electric shock. Existing technology provides a smart socket (application number CN201510993156.9), including a controller, at least one socket unit, and switches connected to each socket unit. Each switch is connected to the controller. Each socket in the socket unit is equipped with a line sensor, and the infrared sensor is connected to the controller. The infrared sensor is used to detect whether an object is inserted into the socket. The controller determines whether all infrared sensors in the same socket unit simultaneously detect an object being inserted. If only some infrared sensors in the same socket unit detect an object being inserted, a prompt message is sent to the user to indicate that the same socket unit is unsafely plugged in.
[0003] The existing smart socket technology relies on infrared sensors to detect foreign objects inserted into the socket. When the sensing control unit malfunctions, it inevitably fails to provide timely warnings. Furthermore, it cannot directly prevent dangers from occurring, inevitably posing a technical risk of electric shock to children. Summary of the Invention
[0004] The purpose of this invention is to provide a smart socket that addresses the technical problem of children accidentally touching existing smart sockets.
[0005] To achieve the above objectives, an embodiment of the present invention provides a smart socket, comprising a housing and a first contact piece, a second contact piece, a third contact piece, a T-shaped sliding blocking device, and a contact piece separating device installed within the housing. The top of the housing has three sockets, each corresponding to one of the first, second, and third contact pieces respectively. Each of the first, second, and third contact pieces has a resilient connector at its bottom, which passes through the bottom of the housing. The three ends of the T-shaped sliding blocking device extend to block the first, second, and third contact pieces respectively. The separating device is located between the first contact piece and the second contact piece, and the two ends of the separating band of the contact piece separating device extend to the bottom of the first contact piece and the second contact piece, respectively. Two separating plates are provided at intervals on one side of the separating band, and each of the two separating plates is provided with a power connection hole. The two separating plates can be moved to the bottom of the first contact piece and the second contact piece, respectively. One end of the two control springs of the contact piece separating device extends to the top of the first contact piece and the second contact piece, respectively. The other end of the two control springs is connected to the center position of the separating band, which is used to pull up the center position of the separating band and drive the two separating plates to move synchronously.
[0006] Preferably, the contact plate separating device further includes a fixed shell and a telescopic device. The fixed shell is fixedly installed inside the housing. The two control springs are movably installed inside the fixed shell, and protrusions are provided on the opposite sides of the two control springs. The protrusions are engaged with the inner sidewall of the fixed shell. The telescopic device is fixedly installed at the bottom of the fixed shell, and the separating strip is sleeved on the rotating shaft at the two telescopic ends of the telescopic device.
[0007] Preferably, the top ends of the two control springs are bent and extended upwards toward the first contact piece and the second contact piece, respectively.
[0008] Preferably, the T-shaped sliding blocking device includes a T-shaped plate and a spring. The T-shaped plate is slidably installed at the top position inside the housing, and the three ends of the T-shaped plate extend to the top positions of the first contact piece, the second contact piece, and the third contact piece, respectively. One end of the spring abuts against the protrusion at the top of the housing, and the other end of the spring abuts against the top protrusion of the T-shaped plate.
[0009] Preferably, one end of the T-shaped plate is provided with a beveled upright plate, the beveled upright plate is located above the third contact piece and below one of the insertion holes, and the inclined surface of the beveled upright plate is located below the insertion hole and is inclined downward in the direction originally away from the T-shaped plate.
[0010] Preferably, the housing includes a base and a mounting cover. The base has an upward-facing mounting groove. The first contact piece, the second contact piece, the third contact piece, and the contact piece separating device are all located in the mounting groove. The T-shaped sliding shielding device is installed at the bottom of the mounting cover.
[0011] Preferably, the side of the mounting cover is provided with a plurality of fixing protrusions, and all the fixing protrusions are located at the same horizontal height.
[0012] Preferably, a plurality of guide grooves are provided on the inner sidewall of the mounting groove, and each guide groove is located near the top plane of the base. The guide grooves penetrate the top plane of the base, and each guide groove corresponds to each of the fixing protrusions.
[0013] Preferably, the top of the housing is provided with a plurality of closed annular protrusions, each of the annular protrusions surrounding the opening of each of the insertion holes.
[0014] Preferably, the flexible connector includes a terminal block, a reset component, and a contact block. The terminal block passes through the bottom surface of the housing and connects to an external wire. A clearance groove is provided on the top of the terminal block. The reset component and the contact block are both located in the clearance groove. The contact block engages with the opening of the clearance groove, and both ends of the reset component abut against the contact block and the bottom of the clearance groove, respectively.
[0015] The smart socket provided in this invention has at least one of the following technical effects:
[0016] The smart socket of this invention includes a housing, a first contact piece, a second contact piece, a third contact piece, a T-shaped sliding blocking device, and a contact piece separating device. During assembly, the first, second, and third contact pieces, the T-shaped sliding blocking device, and the contact piece separating device are all installed inside the housing. The bottoms of the first, second, and third contact pieces are all abutted against elastic connectors. One end of each elastic connector passes through the bottom of the housing, and the other end elastically abuts against the bottom of the first, second, and third contact pieces. The first, second, and third contact pieces are arranged in a triangular pattern, with the first and second contact pieces facing each other. The contact piece separating device is located between the first and second contact pieces. Two control springs in the contact piece separating device extend from one end to the top of the first and second contact pieces, respectively, and from the other end to the center of the separating strip of the lower contact piece separating device, connecting to the upper separating strip. Due to the separation strip… Two partition plates are provided at the edge, with electrical connection holes on the partition plates. When the bending end of the control spring is squeezed and bent by an external foreign object, it pulls the other end upward, thereby pulling the partition strip upward and pulling the partition plates at both ends towards the middle, so that the electrical connection holes on the partition plates correspond to the elastic connectors. This allows the elastic connectors located below the first and second contacts to connect the circuit and achieve power supply. When the original state is restored, the two electrical connection holes separate, and the partition plates separate the first and second contacts from the elastic connectors, achieving the effect of power off. When only one socket is inserted with a foreign object, because the partition plates do not move completely, the contact between the first and second contacts and the elastic connectors is still separated, achieving the effect of power off. Through the above structure, even if accidental contact occurs, as long as the neutral and live wires are not inserted into the sockets at the same time, the problem of electric shock risk can be prevented.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.
[0036] In one embodiment of the present invention, such as Figures 1-5As shown, a smart socket is provided, including a housing 10 and a first contact piece 20, a second contact piece 30, a third contact piece 40, a T-shaped sliding blocking device 50, and a contact piece separating device 60 installed within the housing 10. The top of the housing 10 has three sockets, corresponding to the first contact piece 20, the second contact piece 30, and the third contact piece 40 respectively. The first contact piece 20 and the second contact piece 30 are used to connect the neutral wire and the live wire, respectively, and the third contact piece 40 is used to connect the ground wire. The T-shaped sliding blocking device 50 is used to block the sockets when not in use. The T-shaped sliding blocking device 50 is used to block the plug when it is inserted into the socket, causing the T-shaped plate 51 to move and leave space for the three sockets, thus completing the plug insertion. The bottom of the first contact 20, the second contact 30, and the third contact 40 are all provided with elastic connectors 21. The elastic connectors 21 can be freely adjusted to abut against the first contact 20, the second contact 30, and the third contact 40, and the elastic connectors 21 pass through the bottom of the housing 10. The three ends of the T-shaped sliding blocking device 50 extend to block the first contact 20. The second contact 30 and the third contact 40 synchronously control the first contact 20, the second contact 30, and the third contact 40. A contact separator 60 is located between the first contact 20 and the second contact 30, and the separator band 64 of the contact separator 60 extends to the bottom of the first contact 20 and the second contact 30 respectively, for connecting the first contact 20 and the second contact 30 to the live wire and the neutral wire. Two separator plates 641 are spaced apart on one side of the separator band 64, and each separator plate 641 has a contact hole 642. The partition 641 can be moved to below the first contact piece 20 and the second contact piece 30 respectively. One end of the two control springs 63 of the contact piece separating device 60 extends above the first contact piece 20 and the second contact piece 30 respectively. The other end of the two control springs 63 is connected to the center position of the separating strip 64, which is used to pull up the center position of the separating strip 64 and drive the two partition plates 641 to move synchronously. When the control springs 63 lift the separating strip 64, the telescopic device 62 located at the bottom of the contact piece separating device 60 retracts, and the two rotating shafts located on the telescopic device 62 move closer to each other.
[0037] The smart socket of this invention includes a housing 10, a first contact piece 20, a second contact piece 30, a third contact piece 40, a T-shaped sliding blocking device 50, and a contact piece separating device 60. During assembly, the first contact piece 20, the second contact piece 30, the third contact piece 40, the T-shaped sliding blocking device 50, and the contact piece separating device 60 are all installed inside the housing 10. The bottoms of the first contact piece 20, the second contact piece 30, and the third contact piece 40 all abut against a resilient connector 21. One end of each resilient connector 21 passes through the bottom of the housing 10, and the other end of each resilient connector 21... The first contact piece 20, the second contact piece 30, and the third contact piece 40 are elastically abutted against the bottom of the third contact piece 40. The third contact piece 40 and the first contact piece 20 are arranged in a triangle. The first contact piece 20 and the second contact piece 30 are arranged opposite each other. The contact piece separating device 60 is located between the first contact piece 20 and the second contact piece 30. One end of each of the two control springs 63 in the contact piece separating device 60 extends above the first contact piece 20 and the second contact piece 30, and the other end extends to the center of the separating band 64 of the lower contact piece separating device 60, opposite to the upper separating band 64. The system is interconnected. Since the edge of the separating strip 64 has two separating plates 641, and each separating plate 641 has a power contact hole 642, when the bent end of the control spring 63 is squeezed and bent by an external foreign object, it pulls the other end upwards, thereby causing part of the separating strip 64 to be pulled upwards. This pulls the separating plates 641 at both ends to move towards the middle, so that the power contact hole 642 on the separating plate 641 corresponds to the elastic connector 21. This allows the elastic connector 21, located below the first contact piece 20 and the second contact piece 30, to achieve circuit connection and energize the system. When the original state is restored, the two electrical terminals 642 separate, and the partition plate 641 separates the first contact piece 20 and the second contact piece 30 from the contact with the elastic connector 21, achieving the effect of power disconnection. When only one socket is inserted with a foreign object, because the partition plate 641 does not move completely, it still separates the contact between the first contact piece 20 and the second contact piece 30 and the elastic connector 21, achieving the effect of power disconnection. Through the above structure, even if accidental contact occurs, as long as the neutral and live wires are not inserted into the sockets at the same time, the problem of electric shock risk can be prevented.
[0038] In another embodiment of the invention, such as Figure 2 and Figures 4-5As shown, the contact plate separating device 60 also includes a fixed shell 61 and a telescopic device 62. The telescopic device 62 allows the distance between the two ends of the separating strip 64 to be changed. The fixed shell 61 is fixedly installed inside the housing 10. Two control springs 63 are movably installed inside the fixed shell 61. Each of the two opposite sides of the control springs 63 is provided with a protrusion. The protrusion is engaged with the inner wall of the fixed shell 61. When the control springs 63 deform, the protrusion disengages from the engagement with the inner wall of the fixed shell 61. The telescopic device 62 is fixedly installed at the bottom of the fixed shell 61. The separating strip 64 is sleeved on the rotating shaft on the two telescopic ends of the telescopic device 62. The telescopic device 62 can extend and retract so that the adjustment of the distance between the two ends of the separating strip 64 is not affected.
[0039] In another embodiment of the invention, such as Figure 2 and Figures 4-5 As shown, the tops of the two control springs 63 are bent and extended upwards toward the first contact 20 and the second contact 30, respectively, which can accurately locate foreign objects inserted into the first contact 20 and the second contact 30. When subjected to force, the control springs 63 bend, causing the other end of the control springs 63 to move upwards, causing the distance between the two ends of the separator 64 to shrink, thereby causing the two separator plates 641 on the separator 64 to move, and the electrical connection holes 642 on the separator plates 641 to align, so as to realize the circuit connection of the first contact 20 and the second contact 30.
[0040] In another embodiment of the invention, such as Figure 2 As shown, the T-shaped sliding blocking device 50 includes a T-shaped plate 51 and a spring 52. The T-shaped plate 51 is slidably installed at the top position inside the housing 10, and the three ends of the T-shaped plate 51 extend to the top positions of the first contact piece 20, the second contact piece 30 and the third contact piece 40, respectively. One end of the spring 52 abuts against the protrusion at the top inside the housing 10, and the other end of the spring 52 abuts against the top protrusion of the T-shaped plate 51. The T-shaped plate 51 moves by pressing the spring 52 under force. When the foreign object is pulled out, the spring 52 returns to blocking the socket under the reset action of the spring 52.
[0041] In another embodiment of the invention, such as Figure 2 As shown, one end of the T-shaped plate 51 is provided with a beveled plate 511. The beveled plate 511 is located above the third contact piece 40 and below a socket. The inclined surface of the beveled plate 511 is located below the socket and is inclined downward in the direction originally away from the T-shaped plate 51. The addition of a beveled plate 511 with an inclined surface makes it easier for the socket to be inserted and push the T-shaped plate 51 to move more smoothly.
[0042] In another embodiment of the invention, such as Figure 2As shown, the housing 10 includes a base 12 and a mounting cover 11. The base 12 has an upward-facing mounting groove 121. The first contact piece 20, the second contact piece 30, the third contact piece 40, and the contact piece separating device 60 are all located in the mounting groove 121. The T-shaped sliding shielding device 50 is installed at the bottom of the mounting cover 11. The mounting groove 121 provides mounting positions for the first contact piece 20, the second contact piece 30, the third contact piece 40, and the contact piece separating device 60, and also plans the relative positions between the first contact piece 20, the second contact piece 30, and the third contact piece 40.
[0043] In another embodiment of the invention, such as Figure 2 As shown, the side of the mounting cover 11 is provided with several fixing protrusions 111, and each fixing protrusion 111 is located at the same horizontal height. The fixing protrusions 111 on the side of the mounting cover 11 can effectively prevent the mounting cover 11 from being easily removed after assembly, thereby improving the overall safety of the socket.
[0044] In another embodiment of the invention, such as Figure 2 As shown, a number of guide grooves 122 are provided on the inner sidewall of the mounting groove 121, and each guide groove 122 is located near the top plane of the base 12. The guide groove 122 penetrates the top plane of the base 12. Each guide groove 122 is respectively provided in correspondence with each fixed protrusion 111. Multiple guide grooves 122 are provided on the inner sidewall of the mounting groove 121 in correspondence with the fixed protrusion 111, so that the assembly of the mounting cover 11 is smoother.
[0045] In another embodiment of the invention, such as Figures 1-2 As shown, the top of the housing 10 is provided with several closed annular protrusions, each annular protrusion surrounding the opening of each socket. The annular protrusions at the sockets make it easier for users to find the socket position, and make it more accurate to find the socket position when visibility is poor.
[0046] In another embodiment of the invention, such as Figures 4-5 As shown, the flexible connector 21 includes a terminal block 211, a reset member 212, and a contact block 213. The terminal block 211 passes through the bottom surface of the housing 10 and connects to the external wire. A clearance groove is provided on the top of the terminal block 211. The reset member 212 and the contact block 213 are both located in the clearance groove. The contact block 213 is engaged with the opening of the clearance groove, and the two ends of the reset member 212 abut against the contact block 213 and the bottom of the clearance groove, respectively. Under the action of the reset member 212, the contact block 213 always maintains an upward movement trend, so that the passage of the partition plate 641 can interact with the reset member 212 to change the contact between each contact block 213 and the first contact piece 20 and the second contact piece 30, thereby realizing the connection and disconnection of the circuit.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
