[0003] Although the sockets of the sockets / strips in the prior art are protected by safety baffles, they cannot prevent safety accidents and are likely to become the fuse of the contact. For the convenience of daily use, the sockets are usually placed within reach, but due to children's ignorance and curiosity, they may insert their fingers or other conductive objects into the sockets, causing safety accidents. Moreover, the safety baffles are prone to aging due to frequent plugging and unplugging, and will lose their protective effect.
[0004] In the existing sockets and plugs, the socket device cannot identify the inserted plug device, cannot distinguish or match the corresponding functional socket, and cannot provide power in a targeted manner. Summary of the invention
[0005] In view of the shortcomings of the prior art mentioned above, the purpose of the present invention is to provide an identifiable safety socket based on electronic tag technology, which is used to solve the technical problems in the prior art that the socket has poor safety protection function, is prone to cause safety accidents, and the socket cannot effectively identify the plug that matches it.
[0006] To achieve the above-mentioned purpose and other related purposes, the present invention provides an identifiable safety socket based on electronic tag technology, comprising a plug and a socket, wherein the plug has an electronic tag built in, and the socket comprises a base, a PCB board and a socket cover arranged in sequence from bottom to top, wherein the PCB board is fixed in the base, and a plurality of groups of female plug sockets and contacts are arranged on the PCB board, and a plug-in group is arranged above the female plug socket;
[0007] The plug-in group includes a detection needle, a single plug-in B, a single plug-in A and an induction coil arranged in sequence from bottom to top. The induction coil is used to identify the electronic tag. The detection needle is plugged into one side of the bottom of the single plug-in B, located directly above the contact, and the top of the detection needle is in contact with the single plug-in A.
[0008] In one embodiment of the present invention, a fixing ring is disposed on the side of the single plug-in unit B, a spring ring is disposed on the outside of the detection needle, and the detection needle and the spring ring are both located inside the fixing ring.
[0009] In one embodiment of the present invention, the single plug-in B is provided with a triangular socket, a slide groove and a round hole, the round hole and the slide groove are located in the middle of the triangular socket, and the round hole is located on both sides of the slide groove, and a receiving groove is provided at the bottom of the triangular socket, and the top of the pin socket is located in the receiving groove.
[0010] In one embodiment of the present invention, the single plug-in A is composed of a first blocking member and a second blocking member, a strip through hole is formed between the first blocking member and the second blocking member, and a connecting surface between the second blocking member and the strip through hole is a beveled surface.
[0011] In one embodiment of the present invention, the first blocking member and the second blocking member are respectively provided with a first guide rod and a second guide rod at the bottom, the first guide rod, the second guide rod and the strip through hole are located on the same straight line, and the first guide rod and the second guide rod are both located in the slide groove.
[0012] In one embodiment of the present invention, one end of the second guide rod is provided with an angled angle, and the top of the detection needle contacts the inclined surface of the angled angle.
[0013] In one embodiment of the present invention, a spring is connected between the first blocking member and the single plug-in unit B, and the expansion and contraction direction of the spring is consistent with the length direction of the slide slot.
[0014] In one embodiment of the present invention, the induction coil is located above the first blocking member and the strip-shaped through hole, and the wires of the induction coil enter the circular hole from both sides of the strip-shaped through hole and extend to the bottom to be connected to the PCB board.
[0015] As described above, the present invention has the following beneficial effects:
[0016] 1. In the present invention, the induced magnetic field of the induction coil is about 10mm. After the magnetic field passes through the obstacle, the induced magnetic field will be shortened by 1-2mm, that is, the detection distance is about 8-9mm. When the plug is completely inserted into the plug socket, the distance between the induction coil of the socket and the electronic tag in the plug is about 6mm. On the whole, only when the plug is almost completely inserted into the plug socket, the electronic tag can be placed in the magnetic field of the induction coil, and the induction coil can normally identify the electronic tag and determine whether it is a power supply ID.

[0030] See also Figure 1 The present invention provides an identifiable safety socket based on electronic tag technology, including a plug 1 and a socket 2, wherein the plug 1 has an electronic tag 11 built in. Figure 3 The socket 2 includes a base 21, a PCB board 22 and a socket cover 23 arranged in sequence from bottom to top. The PCB board 22 is fixed in the base 21. A plurality of groups of female plug sockets 24 and contacts 25 are arranged on the PCB board 22, and a plug-in group 3 is arranged above the female plug socket 24. It should be noted that one group of female plug sockets 24 and contacts 25 corresponds to one plug-in group 3. A power cord 26 is also connected to the PCB board 22;
[0031] For details, please refer to Figure 2 The plug 1 also includes a plug cover 12, an inner lining 13, a plug 14 and a wire 15. The plug 14 is connected to the bottom surface of the inner lining 13. The plug cover 12 is arranged above the inner lining 13 and is fixedly connected to the inner lining 13. Preferably, in this embodiment, the electronic tag 11 is first injection molded into the inner lining 13, and the wire 15 is welded to the inner lining 13, and then the plug 14 is welded to the bottom surface of the inner lining 13.
[0032] See also Figure 4 The plug-in group 3 includes a detection needle 31, a single plug-in B33, a single plug-in A32 and an induction coil 34 arranged in sequence from bottom to top. The induction coil 34 is used to identify the electronic tag 11. The detection needle 31 is plugged into one side of the bottom of the single plug-in B33 and is located directly above the contact 25. The top of the detection needle 31 is in contact with the single plug-in A32.
[0033] See also Figure 7 , Figure 8 Specifically, screw holes 331 are provided on both sides of the single plug-in unit B33, and screws are passed through the screw holes 331 to connect with the socket strip cover 23, thereby fixing the single plug-in unit B33 with the socket strip cover 23.
[0034] In this embodiment, the detection needle 31 is arranged corresponding to the position of the contact 25 , and the detection needle 31 is used to detect whether the plug 14 is fully inserted into place. When the plug 14 is fully inserted into place, the detection needle 31 is pressed down so that the bottom of the detection needle 31 contacts the contact 25 .
[0035] In this embodiment, the induced magnetic field of the induction coil 34 is about 10mm. After the magnetic field passes through the obstacle, the induced magnetic field will be shortened by 1-2mm, that is, the detection distance is about 8-9mm. When the plug 14 is completely inserted into the plug socket 24, the distance between the induction coil 34 of the socket 2 and the electronic tag 11 in the plug 1 is about 6mm. On the whole, only when the plug 1 is almost completely inserted into the plug socket 24, the electronic tag 11 can be placed in the magnetic field of the induction coil 34, and the induction coil 34 can normally identify the electronic tag 11 and determine whether it is a power-supply ID. Here is the second detection of whether the plug 14 is in place;
[0036] When the bottom of the detection needle 31 contacts the contact 25 and the electronic tag 11 is placed in the magnetic field of the induction coil 34, the power of the plug socket 24 is turned on, and the plug 11 is energized at this time; when the plug 1 is pulled out a little, so that the electronic tag 11 is placed outside the induced magnetic field of the induction coil 34 or the bottom of the detection needle 31 leaves the contact 25, the induction coil 34 cannot sense the existence of the plug 1, and the plug socket 24 is immediately powered off.
[0037] It should be noted that the electronic tag 11 shown contains a specific "identity code" (pre-set in the electronic tag 11 of the plug 1 according to different electrical appliances). When the electronic tag 11 is placed within the magnetic field of the induction coil 34 in the socket 2, the reader / writer in the PCB board 22 sends a radio frequency signal through the induction coil 34. The electronic tag 11 emits the "identity code" information stored in the chip by means of the energy obtained by the induced current. The reader / writer then gives corresponding operations according to the permissions set by the user (power on / off / limited power, etc., the default identity authorization is the pass state, and the "identity code" is not classified and controlled, and the function of powering on is only realized when the plug 1 is fully inserted) (the comparison of the "identity code" is realized by software control, and the operation of the software can be connected and set / controlled by the APP on the mobile phone. This part of the functions are all prior art).
[0038] The double detection mechanism can ensure that plug 1 and socket 2 are in full contact, completely avoiding the risk of sparks and providing great security.
[0039] Based on the above embodiment, a fixing ring 332 is provided on the side of the single plug-in unit B33, and a spring ring 311 is provided on the outside of the detection needle 31. The detection needle 31 and the spring ring 311 are both located in the fixing ring 332. When force is applied to the top of the detection needle 31, the detection needle 31 moves downward and presses down the spring ring 311. When the force is removed, the detection needle 31 moves upward and returns to its original state under the rebound action of the spring ring 311.
[0040] Based on the above embodiment, the single plug-in unit B33 is provided with a triangular jack 333, a slide groove 334 and a round hole 335, wherein the round hole 335 and the slide groove 334 are located in the middle of the triangular jack 333, and the round hole 335 is located on both sides of the slide groove 334, and a receiving groove 336 is provided at the bottom of the triangular jack 333, and the top of the female plug seat 24 is located in the receiving groove 336;
[0041] Specifically, the slide slot 334 and the top plug hole of the triangular plug hole 333 are located on the same straight line, and the wire 341 of the induction coil 34 passes through the circular hole 335 and extends to the PCB board 22 at the bottom.
[0042] See also Figure 5 , Figure 6 Based on the above embodiment, the single plug-in A32 is composed of a first blocking member 321 and a second blocking member 322, a strip-shaped through hole 323 is formed between the first blocking member 321 and the second blocking member 322, and a connecting surface between the second blocking member 322 and the strip-shaped through hole 323 is a chamfered surface 324;
[0043] In this embodiment, when the single plug-in A32 is located on the single plug-in B33, the first blocking member 321 blocks the two oblique insertion holes of the triangular insertion hole 333, and the second blocking member 322 blocks the insertion hole at the top of the triangular insertion hole 333; when the plug 1 is inserted into the socket 2, the top plug 14 contacts the chamfered surface 324, and when pressed down with force, the chamfered surface 324 is pushed toward the other side away from the first blocking member 321, so that the entire single plug-in B33 moves in the above direction to expose the triangular insertion hole 333, so that the plug 14 can be normally inserted into the triangular hole;
[0044] It should be noted that the strip-shaped through hole 323 is aligned with the top plug hole of the triangular plug hole 333 .
[0045] Based on the above embodiment, the first blocking member 321 and the second blocking member 322 are respectively provided with a first guide rod 325 and a second guide rod 326 at the bottom, the first guide rod 325, the second guide rod 326 and the strip through hole 323 are located on the same straight line, and the first guide rod 325 and the second guide rod 326 are both located in the slide groove 334, and the slide groove 334 plays a guiding role, so that the single plug-in A32 moves along a straight line on the single plug-in B33.
[0046] Based on the above embodiment, a bevel 327 is provided at one end of the second guide rod 326, and the top of the detection pin 31 contacts the inclined surface of the bevel 327. During the movement of the second guide rod 326, the bevel 327 pushes the detection pin 31 downward. Only when the pin 14 is fully inserted into the pin socket 24 and the single plug-in A32 moves to the preset position, can the detection pin 31 move downward to contact the contact 25, so as to detect whether the pin 14 is inserted in place.
[0047] Based on the above embodiment, a spring 35 is connected between the first blocking member 321 and the single plug-in B33. The expansion and contraction direction of the spring 35 is consistent with the length direction of the slide groove 334. When the pin 14 is inserted, the single plug-in A32 moves along a straight line on the single plug-in B33 to compress the spring 35. When the pin 14 is pulled out, the spring 35 rebounds and the single plug-in A32 returns to its original position.
[0048] Based on the above embodiment, the induction coil 34 is located above the first blocking member 321 and the strip-shaped through hole 323, and the wire 341 of the induction coil 34 enters the circular hole 335 from both sides of the strip-shaped through hole 323, and extends to the bottom to connect with the PCB board 22;
[0049] Preferably, the first blocking member 321 is further provided with a gap, and the gap is located at the position of the wire 341 . When the first blocking member 321 moves, the wire 341 enters the gap, and the induction coil 34 does not move.
[0050] Working principle: When the plug 1 is inserted into the socket 2, the single plug-in A32 moves during the downward pressure of the plug 14. During the movement of the single plug-in A32, the bevel 327 applies a downward force to the detection needle 31, causing the detection needle 31 to move downward. When the plug 14 reaches the specified position, the bottom of the detection needle 31 is connected with the contact 25. At the same time, the electronic tag 11 in the plug 1 is placed in the magnetic field of the induction coil 34. At this time, the power supply of the plug socket 24 of the circuit board is turned on, and the plug 14 is energized.
[0051] In summary, the present invention uses the induction coil and the electronic tag in combination, and the detection needle and the contact point cooperate to not only determine whether the plug is inserted in place, but also play a role in identifying the plug, achieving a double safety protection effect. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
[0052] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
