The circuit can be realized by an external power supply, or by RFID radio frequency identification technology. Different circuit functions can be realized according to the connected electronic components. A disconnected circuit has two access points, and all electronic components are connected between the two access points. The access point of the circuit can also be called a connection point. The access point of the circuit refers to the point that can connect the circuit. The access point is attached to a physical mechanical component. The component can be a conductive sheet, a conductive block or a conductive plate, etc. It can also be composed of one end of the wire, a conductive sheet, a conductive block, a conductive plate and the exposed part of the wire to form a conductive area (also called a conductive cell). The conductive area is composed of countless conductive contacts. Connecting any conductive contact will connect to the corresponding circuit. When there is current in the circuit, the circuit will perform corresponding work. In the utility model, "connected or electrically connected to two conductive contacts of the circuit", the two conductive contacts refer to two conductive contacts located at two access points at both ends of the circuit. Two disconnected circuits are connected by connecting two of four conductive contacts, thereby connecting the two disconnected circuits into a closed circuit. In the present utility model, the definition of the orthographic projection of an object on a horizontal plane refers to the part of the object projection above the horizontal plane. The electrical connection in the present utility model refers to the direct contact of the mechanical structure of the access point of the circuit to connect the circuits. In the present utility model, the seal body, plate body, electronic seal column, and plastic plate body all refer to the seal body, but they are called differently in different embodiments and can be marked with the same number 10.

[0041] Please refer to Figure 1 and Figure 2The utility model discloses an electronic seal 100 that can be connected to an external circuit. The electronic seal 100 includes a seal body 10, at least one circuit and a blocking structure 12. The circuit is installed in the seal body 10. The seal body 10 is generally plate-shaped. The plate-shaped seal body 10 includes an upper surface, a lower surface and a side surface between the upper surface and the lower surface. One side surface is the front end of the seal body 10, and the side opposite to the front end is the rear end. During the operation of the seal body 10, the front end of the seal body 10 specifies the forward direction. The conductive parts 11 connected to different ends of different circuits are different conductive parts 11. The seal body 10 plays a protective role and a mounting carrier role for the circuit. At least two access points of one circuit are installed on the surface of the seal body 10. The part of the access point exposed to the seal body 10 is called the conductive part 11. The surface of the conductive part 11 is a conductive contact surface (not marked). The conductive contact of the conductive part 11 contacts the access point of the external circuit to realize the connection between the two circuits. The maximum length dimension of the conductive part 11 is a, 0cm<a≤100cm, and the maximum width dimension of the conductive part 11 is b, 0cm<b≤100cm. The conductive part 11 has a certain length and width and is called a conduction section. That is, in the utility model, the conductive part 11 and the conduction section refer to the same mechanical structure. The electronic seal 100 also includes at least one blocking structure 12. The blocking structure 12 is used to block and limit the external connection components that touch it. The blocking structure 12 is located on the seal body 10;

[0042] Wherein, the circuit in the seal body 10 can be a connection circuit that plays a connecting role, a connection circuit that plays a regulating role or an RFID radio frequency circuit.

It can also be a conductive area with relatively large length and width, such as the conductive part 11 length dimension is 100cm, and the width dimension of the conductive part 11 is 100cm. The conductive part 11 length dimension can be 0.1cm, 1.0cm, 2cm, 3cm, 4cm, 4.5cm, 10cm, 30cm, 50cm, 70cm, 99.9cm, etc., and the conductive part 11 width dimension can be 0.1cm, 1.0cm, 2cm, 3cm, 4cm, 4.5cm, 10cm, 30cm, 50cm, 70cm, 99.9cm, etc. Design according to the needs of the utility model.

[0043] In the first embodiment of the utility model, among the circuits in the seal body 10, one of the circuits is named as the first circuit (not shown), and two access points of the first circuit are installed on the surface of the seal body 10, and the electronic seal 100 is slidably connected and matched with an external component having a circuit. When the conductive contacts of the two conductive parts 11 of the first circuit touch the two access points of an external circuit, the first circuit is connected with the external circuit to become a connected circuit.

[0044] In the first embodiment of the utility model, the electronic seal 100 also includes at least one radio frequency IC chip (not shown), which is installed in the circuit in the seal body 10, and one of the radio frequency IC chips is connected to the first circuit. When the first circuit is connected to the external circuit, the radio frequency IC chip connected to the first circuit can be read by the outside world. For example, the second circuit (not shown) in the external circuit is installed on the external connection component (not shown), and the second circuit includes two access points, and the two access points of the second circuit are partially or completely protruding on the surface of the external connection component. A radio frequency antenna is connected between the two access points of the second circuit, and the radio frequency antenna matches the radio frequency IC chip in the first circuit. When the conductive contacts of the two conductive parts 11 of the first circuit touch the conductive contacts of the two access points of the second circuit, the first circuit and the second circuit are connected to form a circuit using RFID technology, and the reader used in conjunction with the circuit can read the information in the radio frequency IC chip. Of course, other electronic components such as resistors, capacitors, amplifiers, regulators, etc. are also provided in the circuit formed by the first circuit and the second circuit, which will not be introduced one by one.

[0045] It can be understood that the seal body 10 also includes other circuits, and the external connection component also includes other circuits. The other circuits in the seal body 10 are connected with the other circuits in the external connection component before, after, or synchronously with the connection between the first circuit and the second circuit. For example, the seal body 10 also includes a third circuit, and the external connection component includes a fourth circuit. The connection between the third circuit and the fourth circuit is prior to the connection between the first circuit and the second circuit, which plays a prompting role, etc. The circuit formed by the combination of the third circuit and the fourth circuit can be provided with a display light, a buzzer, etc. Examples are not given here one by one.

[0046] Please refer to Figures 1 to 3In the first embodiment of the utility model, the lower surface of the seal body 10 is provided with convex ribs 13 arranged in parallel and at intervals, and the adjacent convex ribs 13 are substantially parallel and do not intersect each other. The convex ribs 13 extend along the direction where the front and rear ends of the seal body 10 are located, and two adjacent convex ribs 13 and the plate body therebetween form a sliding groove 131, and the front and rear ends of the sliding groove 131 are both open. The two conductive parts 11 of the first circuit are located on the bottom walls of the two sliding grooves 131, and the length direction of the two conductive parts 11 of the first circuit is substantially parallel to the length direction of the convex ribs 13, and the width dimension of the two conductive parts 11 of the first circuit is substantially consistent with or close to the width dimension of the bottom wall of the sliding groove 131. The access point of the second circuit includes a conductive hook claw, which includes a hook portion, and the surface of the hook portion is a conductive contact surface. The electronic seal 100 is pushed so that the two hook portions of the second circuit slide into the two sliding grooves 131 and abut or support the bottom walls of the two sliding grooves 131. The sliding grooves 131 limit the sliding path of the hook portion on the seal body 10, while ensuring the stability and accuracy of the connection between the circuit in the seal body 10 and the circuit on the external connecting component.

[0047] It can be rationally understood that at least two parallel convex ribs 13 are provided on the surface of the seal body 10, and the two parallel convex ribs 13 provided on the surface of the seal body 10 can also play a role in limiting the sliding direction;

[0048] The conductive portion 11 is disposed on the surface of the seal body 10 and is not within the sliding groove 131 , and can also achieve connectivity between the first circuit and the second circuit.

[0049] The conductive portion 11 located in the sliding groove 131 may be located on the bottom wall of the sliding groove 131 or on the side wall of the sliding groove 131;

[0050] The length direction of the conductive part 11 is arranged in parallel with the length direction of the convex rib 13, or the width direction of the conductive part 11 is arranged in parallel with the length direction of the convex rib 13, or the length direction of the conductive part 11 is arranged between the length direction and the width direction of the convex rib 13, according to specific needs;

[0051] The slide groove 131 may also be provided with a bend or curved section to play a role of engagement, such as a slide groove 131 designed in a Z or H shape;

[0052] All the convex ribs 13 are located on the upper surface or the lower surface of the seal body 10, or the upper surface and the lower surface of the seal body 10 are provided with convex ribs 13, or the front end, the rear end and the side of the seal body 10 may also be provided with convex ribs 13;

[0053] All the conductive parts 11 are located on the upper surface or the lower surface of the seal body 10 , or both the upper surface and the lower surface of the seal body 10 are provided with conductive parts 11 , and / or the front end, rear end and side of the seal body 10 may also be provided with conductive parts 11 .

[0054] In the first embodiment of the utility model, a limiting groove 132 is recessed in the bottom wall of the sliding groove 131, and the conductive part 11 is located in the limiting groove 132. The hook part slides from the front end of the seal body 10 into the sliding groove 131 and moves toward its rear end to the position of the limiting groove 132, which increases the sense of the hook part of the external connection component sliding into the limiting groove 132, thereby knowing the connectivity of the two corresponding circuits. At the same time, the limiting groove 132 further plays a limiting role.

[0055] At least one of the limiting grooves 132 includes a first side wall. When the plate-shaped seal body 10 is placed horizontally, the upper surface of the seal body 10 is almost parallel to the horizontal plane, and the bottom wall surface of the limiting groove 132 is roughly flat. When the first side wall is set in the up and down direction, the connection between the first side wall and the bottom wall of the limiting groove 132 is lower than the part of the first side wall away from the connection with the bottom wall of the limiting groove 132. When one first side wall is set in the up and down direction, the other first side walls may be set in the up and down direction, or may be set in other directions. When the first side wall is arranged in the up and down directions, the first side wall corresponds to a first plane. At this time, the first plane is located in the horizontal plane, and the first plane is located below the connection of the corresponding first side wall. The surface of the first side wall and its orthographic projection on the corresponding first plane are arranged at an acute angle to form a blocking structure 12, and the part of the surface of the first side wall away from the bottom wall of the limiting groove 132 is projected on the first plane away from the front end of the seal body 10 relative to the part of the surface of the first side wall connected to the bottom wall of the limiting groove 132. Or the surface of the first side wall coincides with its orthographic projection on the first plane to form a blocking structure 12, and the part of the surface of the first side wall away from the bottom wall of the limiting groove 132 is projected on the first plane at an equal distance from the front end of the seal body 10 relative to the part of the surface of the first side wall connected to the bottom wall of the limiting groove 132. The surface of the first side wall is located in a vertical plane, and the surface of the first side wall is supported by a horizontal force, thereby preventing the force-applying object from continuing to move. After the hook portion of the external connection component slides into the limiting groove 132, if the hook portion of the external connection component moves relative to the seal body 10 toward the rear end of the seal body until it abuts against the first side wall, the first side wall blocks the hook portion from continuing to move relative to the seal body 10 toward the rear end of the seal body 10.

[0056] like Figure 4As shown, of course, at least one conductive part 11 is used for fixed connection or detachable connection with the external circuit. Fixed connection includes welding and gluing, etc., and detachable connection includes snap connection and interference fit connection, etc. The conductive part 11 can also be connected to the external circuit by plugging on the sealing plate, or the wire of the circuit of the sealing plate passes through the surface of the sealing plate, extends a certain length and is directly fixedly connected to the external circuit. One conductive part 11 of the RF IC chip circuit forms a conductive section laid on the surface, and another conductive part 11 of the RF IC chip circuit is directly connected to the access point of the external circuit through a wire 30. When the conductive section of the RF IC chip circuit touches the other access point of the external circuit, the two circuits are connected. When the reader / writer suitable for the RF IC chip reads, the RF IC chip is identified.

[0057] The blocking structure 12 has the first side wall in the above two situations. When the first side wall of the blocking structure 12 is not arranged in the up-down direction, the direction of the first plane and the horizontal force applied thereto also changes accordingly, and the relative positional relationship between the first side wall and the first plane and the horizontal force applied thereto remains unchanged. It can be rationally understood that all the conductive parts 11 can be located in the limiting groove 132, one conductive part 11 can be located in one limiting groove 132, or at least two conductive parts 11 can be located in one limiting groove 132, or some conductive parts 11 can be located in the limiting groove 132.

[0058] It can be rationally said that the blocking structure 12 can also be set as other structures as long as the corresponding functions can be achieved. For example, the blocking structure 12 (not shown) includes a sliding slope (not shown) and a blocking surface (not shown). The blocking structure 12 is convexly arranged in the sliding groove 131. The sliding slope and the blocking surface are connected at one end away from the seal body 10 through a connecting portion. When the opening of the sliding groove 131 is arranged upward, the connecting portion is arranged higher than the bottom wall of the sliding groove 131. The angle between the sliding slope and its orthographic projection on the horizontal plane is set at an acute angle. When the sliding slope is subjected to a horizontal force, the force-applying object slides upward along the sliding slope.

[0059] The blocking surface coincides with its orthographic projection on the horizontal plane or is set at an acute angle. When the blocking surface is subjected to a horizontal force, the force-applying object is pressed against the blocking surface and prevented from continuing to move forward.

[0060] The surface of the connecting part is a smooth curved surface, and the curved surface includes a circular curved surface, an arc-shaped curved surface, and an elliptical curved surface.

[0061] The orthographic projections of the sliding slope and the blocking surface on the horizontal plane are located on the same side of the orthographic projection of the connecting part on the horizontal plane, or the orthographic projection of the connecting part on the horizontal plane covers the orthographic projection of the blocking surface on the horizontal plane.

[0062] In the first embodiment of the utility model, the electronic seal 100 also includes a snap-fit ​​structure, which is used to snap-fit ​​and fix with an external connection component so that the electronic seal 100 cannot be withdrawn in the reverse direction, and the snap-fit ​​structure is located at the rear end of the seal body 10; when at least one circuit in the seal body 10 is connected to at least one circuit in the external connection component, the snap-fit ​​structure is snap-fit ​​and fixed with the external connection component.

[0063] Please refer to Figure 3 Specifically, the snap structure includes at least one limiting wing 14, and a limiting wing 14 protrudes from one side of the seal body 10 along the transverse direction. The number of limiting wings 14 can be one, two, or more than two. When the number of limiting wings 14 is two, the two limiting wings 14 are located at the rear end of the seal body 10 and protrude on both sides of the seal body 10. The maximum distance between the two limiting wings 14 is greater than the maximum transverse distance of the seal body 10.

[0064] Or the buckle structure is at least one limiting hole (not shown) formed at the rear end of the seal body 10, and the external connection component is provided with at least one limiting column matched therewith, and the limiting column is inserted into the limiting hole to fix the position of the seal body 10, and the limiting column can be automatically controlled or manually set mechanically, and the electronic seal 100 can be reused, saving the user's use cost. Please refer to Figure 1 , wherein the limiting wing 14 includes a shearing portion 141. When the seal body 10 needs to be withdrawn, the shearing portion 141 of the limiting wing 14 is cut off, thereby cutting off the RF IC chip circuit and pushing out the seal body 10. It can be understood that the shape of the seal body 10 can also be plate-shaped, cylindrical, circular, elliptical, polygonal, cube, irregular shape, etc.;

[0065] The plate-shaped seal body 10 has at least one surface provided with a conductive portion 11 , and the conductive portion 11 is arranged along the length direction of the plate-shaped seal body 10 and / or along the width direction of the plate-shaped seal body 10 .

[0066] The cylindrical seal body 10 is provided with a conductive portion 11 on its axis, and / or on its periphery, and / or at both ends of the cylindrical seal body 10 .

[0067] Please refer to Figure 5In the first embodiment of the utility model, the circuit surface in the seal body 10 is covered with a shaping layer to form the seal body 10. The shaping layer is an insulating material. The insulating material includes insulating paint, insulating glue; fiber products; rubber, plastic and its products; glass, ceramic products; mica, asbestos and its products. The plastic material is formed into a shaping layer by injection molding process. The shaping layer plays a protective role of the shell. The surface of the shaping layer formed by the plastic material can be shaped by opening a plurality of small reinforcing blind holes 16. The reinforcing blind holes 16 play a role in strengthening the strength of the shaping layer and shaping. Of course, the seal body 10 can also be provided with a through hole without affecting the use of the seal body 10. The electronic seal 100 can be provided with a metal sheet inside, and the conductive part 11 is located on one side or both sides of the metal sheet. The metal sheet is wrapped with plastic through an injection molding process to form a seal body 10, and the conductive parts 11 are exposed on the surface of the plastic molding layer. The electronic seal 100 is slidably connected to the external connection component, so that the conductive part 11 is connected to the hook part and the access point in the external connection component, so as to achieve circuit conduction between the two. Among them, the electronic seal 100 produced by the injection molding process can be called an injection molded seal plate, and the seal body 10 can be called a plastic plate body. They are essentially the same, but the names are different. The radio frequency sheet can be called a metal sheet 20. In this article, electrical connection and electrical connection are both direct connections to the circuit.

[0068] Please refer to Figure 5 and Figure 6 Specifically, all the contents of the seal body 10 are arranged on a radio frequency sheet 20, the radio frequency sheet 20 includes a plurality of conductive parts 11 and radio frequency IC chips arranged along the length direction, at least two of the conductive parts 11 are electrically connected to the radio frequency IC chip, the seal body 10 is formed by wrapping the surface of the radio frequency sheet 20 through an injection molding process, the seal body 10 can also be called a plastic plate body, a plurality of parallel convex ribs 13 are formed on the surface of the plastic plate body, two adjacent convex ribs 13 and the plastic plate body therebetween form a sliding groove 131, the conductive part 11 is exposed at the bottom wall of the sliding groove 131, and a plurality of reinforced blind holes 16 arranged at intervals are formed on the other side of the plastic plate body; the radio frequency sheet 20 is also called a metal sheet.

[0069] The two access points of the external circuit are in contact with the two conductive parts 11 of the RF IC chip to make the RF IC chip readable by the outside world. The plastic plate can be provided with a sliding groove 131 on one side and a reinforced blind hole 16 on the other side to increase the strength and shaping of the plastic plate. The reinforced blind hole 16 is circular, polygonal, square, triangular or irregular in shape.

[0070] Please refer to Figure 1The seal body 10 is also provided with at least one receiving hole (not marked), and the hole wall of the receiving hole is fixedly connected with an elastic spine 17, which is elastic and bent, and part of the elastic spine 17 is convex on the surface of the plastic plate. When the plastic plate is accommodated in or inserted into an external connection component, the elastic spine 17 partially abuts against the external connection component and thus plays a role in fixing the plastic plate, so that the relative position relationship between the plastic plate and the external connection component is stable. Due to the elasticity of the elastic spine 17 itself, the relative movement of the two is facilitated under the action of external force. In the first embodiment of the utility model, the bottom wall of the sliding groove 131 is also provided with at least one plug hole 15, and two circuits can be connected through the plug hole 15. For example, the external circuit is connected with the circuit in the plastic plate, and when the plastic plate is pushed forward, the two access points of the external circuit pass through the two plug holes 15 and are connected with the access points of other external circuits.

[0071] It can be understood that the circuit in the seal body 10 can also be separately arranged, and then through gluing or injection molding, the circuit surface in the seal body 10 can also be covered with an insulating layer, and the outer surface of the insulating layer is covered with a shell, and the material of the shell includes a metal material. One elastic spine 17 is accommodated in one accommodation hole, or two elastic spines 17 are accommodated in one accommodation hole, or multiple elastic spines 17 are accommodated in one accommodation hole. The number of elastic spines 17 can be one

[0072] For example, the first circuit in the seal body 10 is located on a metal sheet or a metal block, and the third circuit in the seal body 10 is located on another metal sheet or a metal block. The first circuit and the second circuit are combined together through an injection molding process. Afterwards, the outer surface of the insulating layer is covered with a metal layer to form a shell. Since the plastic material is easy to bend and deform, or the parallel seal body 10 after injection molding is uneven and warped upward, the metal shell plays a role in fixing the shape and also plays a further protective role.

[0073] The bottom wall or side wall of a sliding groove 131 may be provided with one, two, or more than two conductive parts 11, which are arranged at intervals on the inner wall of the sliding groove 131. It can be understood that the bottom wall or side wall of a limiting groove 132 may be provided with one, two, or more than two conductive parts 11.

[0074] In the second embodiment of the present utility model, the difference between the second embodiment and the first embodiment is that the surface of the plate-shaped seal body 10 is not provided with a sliding groove for limiting. Specifically,

For example, a conductive part 11 of the RF IC chip circuit forms a conductive section laid on the surface, and another conductive part 11 of the RF IC chip circuit is directly connected to the access point of the external circuit through a wire. When the conductive section of the RF IC chip circuit touches the other access point of the external circuit, the two circuits are connected, and when the reader / writer suitable for the RF IC chip reads, the RF IC chip is identified.

[0078] Among them, some blocking structures can also be located on the side of the seal body 10 without the conductive part 11, and the position of the blocking structure is set as needed. The circuit in the seal body 10 can be a connecting circuit that plays a connecting role, a connecting circuit that plays a regulating role, or a radio frequency IC chip circuit.

For example, the seal body 10 also includes a third circuit, and the external connection component includes a fourth circuit. The connection between the third circuit and the fourth circuit is before the connection between the RF IC chip circuit and the second circuit, which plays a prompting role, etc. The circuit combined by the third circuit and the fourth circuit can be provided with a display light, a buzzer, etc. Examples are not given here one by one.

[0081] When there is only one limiting wing 14, the limiting wing 14 protrudes from the surface of the seal body 10, and can be located on the upper surface, lower surface, or side surface of the seal body 10. When the electronic seal 100 board cooperates with the external connection component to connect the circuit, the limiting wing 14 is engaged with the external connection component, so that the electronic seal 100 board cannot continue to move forward. When the electronic seal 100 has only two limiting wings 14, the two limiting wings 14 can be located on both sides of the plate-type seal body 10, named as the left limiting wing 14 and the right limiting wing 14, and the connection is roughly located in the middle of the seal body 10, the number of radio frequency IC chips is greater than or equal to one, and at least one radio frequency IC chip is located on the left limiting wing 14 or the right limiting wing 14, and the left limiting wing 14 and the right limiting wing 14 are arranged along the width direction of the seal body 10, the maximum distance between the two limiting wings 14 is greater than the maximum width dimension in the width direction of the seal body 10, the maximum transverse dimension of the connection between the limiting wing 14 and the seal body 10 is less than the maximum transverse dimension of the seal body 10, the distance between the limiting wing 14 and the seal body 10 gradually increases in the transverse direction away from the connection, and the angle between the seal body 10 and the limiting wing 14 is set at an acute angle.

When the seal body 10 needs to be withdrawn, the shearing portion 141 of the limiting wing 14 is cut off, thereby cutting off the RF IC chip circuit and pushing out the seal body 10 .

[0082] In the second embodiment of the utility model, the radio frequency IC chip is located on the side of the limiting wing 14 away from the seal body 10. After the circuit of the seal body 10 is connected to the external circuit, the limiting wing 14 is used for limiting. When the seal body 10 needs to be separated from the external circuit, the limiting wing 14 is cut off, and the radio frequency IC chip is separated from the seal body 10, so that the maximum horizontal dimension of the part of the seal body 10 where the limiting wing 14 is cut off is less than or equal to the maximum horizontal dimension of the seal body 10, and then the seal body 10 is pushed, and the seal body 10 passes through the external connection component with the external circuit.

[0083] In the second embodiment of the utility model, the blocking structure (not shown) includes a sliding slope (not shown) and a blocking surface (not shown), the blocking structure is convexly arranged in the sliding groove, the sliding slope and the blocking surface are connected at one end away from the seal body 10 by a connecting portion, when the opening of the sliding groove is arranged upward, the connecting portion is arranged higher than the bottom wall of the sliding groove, the sliding slope and its orthographic projection on the horizontal plane are arranged at an acute angle, when the sliding slope is subjected to a horizontal force, the force-applying object slides upward along the sliding slope;

[0086] The orthographic projections of the sliding slope and the blocking surface on the horizontal plane are located on the same side of the orthographic projection of the connecting part on the horizontal plane, or the orthographic projection of the connecting part on the horizontal plane covers the orthographic projection of the blocking surface on the horizontal plane.

[0087] In the second embodiment of the utility model, the seal body 10 is provided with at least two conduction sections arranged at intervals along the length direction. The conduction sections can be located on the upper surface, the lower surface, the side surface or any combination thereof of the plate-type seal body 10, that is, the seal body 10 is provided with at least two conduction sections arranged at intervals along the length direction or the width direction. The two conduction sections of the circuit are synchronously connected to the external circuit. The seal body 10 also has at least one jack 15, and the two circuits can be connected through the jack 15. For example, the external circuit is connected to the circuit of the seal body 10, and when the seal body 10 is pushed forward, the two access points of the external circuit pass through the two jacks 15 and are connected to the access points of other external circuits.

The shaping layer is an insulating material. The insulating materials include insulating paint, insulating glue; fiber products; rubber, plastic and its products; glass, ceramic products; mica, asbestos and its products, etc. The plastic material is formed into a shaping layer through an injection molding process. The shaping layer plays a protective role for the shell. The surface of the shaping layer formed by the plastic material can be shaped by opening a plurality of small reinforcing blind holes 16. The reinforcing blind holes 16 play a role in strengthening the strength of the shaping layer and shaping. The shapes of the reinforcing blind holes 16 include circular, polygonal, square and irregular shapes. Of course, the seal body 10 can also be provided with through holes without affecting the use of the seal body 10.

The seal body 10 can be provided with a conductive part on one side, or both sides, or on the side as needed.

[0091] For example, the first circuit in the seal body 10 is located on a metal sheet or a metal block, and the third circuit in the seal body 10 is located on another metal sheet or a metal block. The first circuit and the second circuit are combined together through an injection molding process. Afterwards, the outer surface of the insulating layer is covered with a metal layer to form a shell. Since the plastic material is easy to bend and deform, or the parallel seal body 10 after injection molding is uneven and warped upward, the metal shell plays a role in fixing the shape and also plays a further protective role.

[0092] In the second embodiment of the utility model, at least the surface of the radio frequency IC chip circuit in the plate-type seal body 10 is covered with a shaping layer, two conductive sections or one conductive section of the radio frequency IC chip circuit are located on the surface of the seal body 10, and the plate-type seal body 10 is connected with the external connection component by plugging, so that the radio frequency IC chip circuit is connected to form a circuit through the two conductive sections and the two access points of the circuit located in the external connection component. The circuit includes a radio frequency antenna matching the radio frequency IC chip, and the reading and writing device or the reader can read the radio frequency IC chip information. When the plate-type seal body 10 is dragged in the reverse direction, the blocking structure blocks and restricts the external connection component that touches it, thereby preventing the plate-type seal body 10 from continuing to move in the reverse direction; the limiting wing 14 includes a shearing portion 14. When the plate-type seal body 10 needs to be withdrawn, the shearing portion 14 of the limiting wing 14 is cut off, thereby cutting off the radio frequency IC chip circuit, and the seal body 10 is continuously pushed forward, so that the seal body 10 passes through the external connection component and is withdrawn.

[0093] Of course, in other embodiments, the seal body 10 does not have a sliding groove, but may be provided with a limiting groove (not shown), and the conductive portion 11 or the conductive section is located in the limiting groove.
