[0002] When a device with a circuit needs to be connected to a circuit in an external component, it is often connected through a connection method similar to a connector, such as an electrical plug-in or an electrical socket, and can only achieve the connection of a fixed circuit, and cannot achieve that a circuit in the device can be connected to circuits in different external components at different times;

[0003] In existing devices with circuits, there are circuits controlled by switches inside, or radio frequency circuits in RFID radio frequency identification tags, which can only realize functions such as reading, writing and identification through the circuits themselves.

The moving part presses the hook part and moves forward along the sliding inclined surface. When the hook part presses or abuts the second circuit access point, the first circuit electrically connected to the metal body and the second circuit access point of the moving part are electrically connected and turned on.

[0039] 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. However, it should be understood that without further description, the elements, structures and features in one embodiment can also be beneficially combined with other embodiments.

[0040] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] A circuit is a conductive loop composed of metal wires and electrical and electronic components. When the circuit is connected, it generates current and works. The circuit can work by an external power supply or by RFID radio frequency identification technology. Generally, the circuit works by switching. However, for a device with a disconnected circuit or multiple disconnected circuits, when it needs to be connected to a circuit or multiple circuits in the outside world to work, it can be achieved by one or more conductive claws of the present invention.

[0043] Please refer to Figure 1 and Figure 2The conductive hook of the present invention includes a metal body 100 made of a metal material, and the metal is a conductive metal, and the metal includes silver, copper, aluminum, iron, tungsten and alloys. The metal body 100 includes a hook portion 10, a hook arm 20 and a connecting portion 30. The hook portion 10 is located at one end of the hook arm 20. The hook portion 10 is constructed with a sliding inclined surface 11 and a reverse stop and hold surface 12 that are arranged in opposite directions. The connecting portion 30 is located at the other end of the hook arm 20. The connecting portion 30 is connected to an external connecting component by an elastic connection, and a connecting shaft is constructed at the connection. When the sliding inclined surface 11 is subjected to a force, the conductive hook is compressed downward and moves circumferentially around the connecting shaft. When the force is removed, the conductive hook can bounce upward and return to the initial position, or move toward the initial position, or reset along the original path.

[0044] One end of the metal body 100 is electrically connected to an access point of the first circuit, and an external moving part includes a second circuit, and an access point of the second circuit is located on the surface of the moving part. When the moving part presses the hook part 10 and moves forward, after the front end of the moving part slides over the sliding inclined surface 11, the hook part 10 presses or abuts against a side of the moving part provided with the second circuit access point. When the hook part 10 presses or abuts against the second circuit access point, the conductive hook electrically connects the first circuit and the second circuit at both ends of the moving part.

[0045] When the moving part moves in the reverse direction, that is, in the direction opposite to the forward direction, after the reverse stop abutting surface 12 abuts against the moving part, the reverse stop abutting surface 12 prevents the moving part from continuing to move.

[0046] The technical solution of the present invention is that the metal body 100 itself has conductivity, elastic connection mode and the hook part 10 is provided with a reverse stop and abutting surface 12. The moving part presses the hook part 10 and moves forward along the sliding inclined surface 11. When the hook part 10 supports or abuts the second circuit access point, the first circuit electrically connected to the metal body 100 is electrically connected to the second circuit access point of the moving part and is turned on. When the moving part moves in the opposite direction, the reverse stop and abutting surface 12 engages with the moving part to prevent the moving part from continuing to move, thereby realizing the unidirectional movement function of the conductive claw. The connecting part 30 is connected to the external connecting component through an elastic connection mode. When the moving part presses the conductive claw and moves in the horizontal direction, it is ensured that the hook part 10 always supports the moving part, so that the first circuit and the second circuit are stably connected, which is convenient for the movement of the moving part, realizes the corresponding positioning and signal transmission perception functions, and at the same time increases the movement touch of the hand that pushes the moving part to move.

[0047] Among them, the sliding inclined surface 11 is set away from the hook arm 20, and the reverse stop and support surface 12 is set facing the hook arm 20. The reverse stop and support surface 12 and the adjacent surface of the hook arm 20 form a hook groove 121. The connection between the reverse stop and support surface 12 and the adjacent surface of the hook arm 20 forms a smooth curved surface connection. The hook groove 121 can further limit the reverse movement of the moving part. When the rear end of the moving part slides over the hook part 10, the rear end of the moving part is located in the hook groove 121. During the reverse movement of the moving part, the rear end of the moving part approaches the reverse stop and support surface 12 along the bottom wall of the hook groove 121 and is supported.

[0048] Among them, when the conductive hook is installed in the external connection component, the angle between the sliding slope 11 and its positive projection on the horizontal plane is set at an acute angle, and the reverse stop and hold surface 12 coincides with its positive projection on the horizontal plane or is set at an acute angle. The sliding slope 11 is conducive to the forward sliding of the moving part and has a guiding effect. The sliding slope 11 is a smooth surface to reduce friction. When the sliding slope 11 is subjected to a horizontal force, the conductive hook is compressed downward and moves circumferentially around the connecting axis. When the horizontal force is withdrawn, the conductive hook can bounce upward. It can be understood that after the conductive hook is installed in the external connection component, the spatial position of the connecting part 30 changes, so that the sliding slope 11 and its projection on the horizontal plane change. In the present invention, after the conductive hook is installed in the external connection component, the conductive hook and the external connection component, the sliding slope 11 are subjected to a horizontal force, and the reverse stop and hold surface 12 is subjected to a horizontal force. The relative position relationship between the three remains roughly unchanged, that is, the conductive hook can be installed and set in any space.

[0049] Among them, the closed loop formed by the first circuit and the second circuit includes an RF IC chip and an RF antenna. The RF IC chip is located in the first circuit, and the RF antenna board is located in the second circuit, or the RF IC chip is located in the second circuit, and the RF antenna board is located in the first circuit; or the RF IC chip and the RF antenna board are located in the first circuit, or the RF IC chip and the RF antenna board are located in the second circuit. When the first circuit and the second circuit are connected through a conductive hook, the RF IC chip can be read by the outside world. Of course, the first circuit and the second circuit can be provided with a conductive hook, or two conductive hooks, or more conductive hooks. Multiple conductive hooks can be connected at the same time, or they can be connected asynchronously. For example, when the first circuit and the second circuit are connected through a conductive hook, the RF IC chip can be read by the outside world. Of course, the first circuit and the second circuit include a first conductive hook and The second conductive hook, when the moving part slides to the first preset distance, the first conductive hook and the second conductive hook are connected to the two access points of the second circuit. Of course, the two ends of the first conductive hook and the second conductive hook can also be connected to the two access points of the first circuit and the second circuit respectively; for example two, the first circuit and the second circuit include the first conductive hook, the second conductive hook, the third conductive hook and the fourth conductive hook, the first circuit is disconnected into two connecting circuits, the first circuit and the second circuit include the first conductive hook, the second conductive hook, the third conductive hook and the fourth conductive hook, which are electrically connected to the four access points of the first circuit respectively, when the moving part slides to the first preset distance, the first conductive hook and the second conductive hook are connected to the two access points of the second circuit, when the moving part slides to the second preset distance, the third conductive hook and the fourth conductive hook are connected to the two access points of the second circuit.

[0050] It can be understood that a device may be provided with multiple conductive hooks connected to multiple circuits, and the moving part may be provided with two or more circuits. When the moving part slides to different preset distances, one or two devices are connected to the circuits in the moving part through the conductive hooks to realize the positioning sensing function, that is, the corresponding functions are realized according to the different components provided in the circuit.

[0051] Please refer to Figure 1 and Figure 2Furthermore, the sliding slope 11 intersects with the reverse stop and hold surface 12 and forms an intersecting free end 122. When the conductive hook is installed on the external connection component, the highest points of the sliding slope 11 and the reverse stop and hold surface 12 are both located at the free end 122. When the front end of the moving part slides over the sliding slope 11, the free end 122 supports or abuts the moving part. The surface of the free end 122 is a smooth curved surface, which includes a circular curved surface, an arc curved surface, and an elliptical curved surface. Reducing friction is conducive to sliding. The curved surface allows the free end 122 to fully contact the moving part during sliding. The sliding slope 11 can be a plane, or a curved surface. The curved surface is conducive to guiding the moving part and increasing the guiding acceleration.

[0052] The top of the sliding slope 11 of the hook part and the reverse stop and retreat abutment surface 12 can be connected in other ways, that is, as long as the corresponding function can be achieved, such as the top of the sliding slope 11 and the top of the reverse stop and retreat abutment surface 12 are also connected through a contact surface, the contact surface is used to support or abut with the moving part, and the contact surface is flat or roughly flat, so that the first circuit and the second circuit are electrically connected or conductive; or the sliding slope 11 and the reverse stop and retreat abutment surface 12 intersect and form a straight line or a curve.

[0053] Furthermore, the conductive hook is connected to the external connection component by an elastic connection, and the moving part can move within a limited range during movement. The conductive hook ensures the connectivity between the hook portion 10 of the conductive hook and the moving part through elastic action. If the conductive hook is fixedly connected to the external connection component, when the moving part is detached from the hook portion 10, the hook portion 10 cannot move up and down and is abutted against the moving part, so that the circuit connection is interrupted. The external connection component can be the main body of the device, or it can be a plate-shaped mounting part, or a mounting part of other shapes.

[0054] Please refer to Figure 1 and Figure 2 , further, the metal body 100 is roughly flat or columnar, or other shapes, such as the lower end of the metal body 100 is square, etc.; and / or, the hook arm 20 includes a lifting section 21 and a horizontal connecting section 22 connected to each other, the hook portion 10 is located at the end of the lifting section 21 away from the horizontal connecting section 22, the connecting portion 30 is located at the end of the horizontal connecting section 22 away from the lifting section 21, the upper surface of the horizontal connecting section 22 is a horizontal plane or is roughly horizontal, the distance from the upper surface of the lifting section 21 to the horizontal plane is gradually increased along the direction of the lifting section 21 toward the hook portion 10, the lifting section 21 increases the height of the hook portion 10, and also increases the range of elastic movement up and down, there is no specific requirement for the shape of the lower end of the lifting section 21 and the horizontal connecting section 22, and the thickness and structural design are increased according to the design and use needs. Of course, the hook arm 20 can also be an irregular shape, and the length and thickness are designed according to specific needs.

[0055] Furthermore, the sliding slope 11 and the surface of the adjacent hook arm 20 are roughly V-shaped or U-shaped, which saves materials and thus reduces costs, occupies little space, and / or the intersection of the sliding slope 11 and the surface of the adjacent hook arm 20 is a curved surface; and / or the reverse stop support surface 12 is smoothly connected to the surface of the hook arm 20, so that the inner wall of the hook groove 121 is smooth, thereby enhancing the guiding effect and reducing friction. When the bottom end of the hook arm 20 has a variety of shapes, the thickness and width can be set arbitrarily without affecting use.

[0056] Please refer to Figure 2 and Figure 3 The end of the metal body 100 electrically connected to an access point of the first circuit is located at the connection part 30, and is named as the conducting end 40. The conducting end 40 is a protrusion convexly provided on the connection part 30. The free end of the conducting end 40 is also provided with a groove, which is convenient for connecting with the access point of the circuit. Generally, the wire of the circuit is electrically connected to the conducting end 40 by welding. The groove provided on the conducting end 40 is used for connection, and at the same time plays a role in protecting the connecting end to prevent damage caused by external touch. The conducting end 40 is provided at the connection part 30, and the overall structure is beautiful, and the strength of the connection part 30 is enhanced, which is convenient for the elastic movement of the conductive claw to prevent contact with other structures. The conducting end 40 is provided in the elastic movement direction of the conductive claw.

[0057] Please refer to Figure 4 and Figure 5 Another design method of the conducting end 40 is that the conducting end 40 can protrude from the claw arm 20; or, it can be a groove recessed in the claw arm 20, and the conducting end 40 is located on the inner wall of the groove; or the conducting end 40 is located on the surface of the claw arm 20.

[0058] Please refer to Figures 4 to 7 Further, the surface of the connecting portion 30 is covered with an insulating shaping layer 200, and an annular ring or a semi-annular shape is provided at the connecting portion 30, and an axial hole 31 is opened in the middle of the annular ring or the semi-annular shape. The annular ring is a closed axial hole 31, and the semi-annular shape is an open semicircular axial hole 31. The shaping layer 200 covers the surface of the annular ring or the semi-annular shape. The annular ring or the semi-annular shape has a certain supporting effect, and is convenient for shaping and opening the shaping layer 200. The shaping layer 200 is made of plastic material, and of course it can also be other insulating layer materials, such as urea-formaldehyde resin, aniline formaldehyde resin, melamine formaldehyde resin, glycerin resin, silk, cotton yarn, cotton cloth and their mixed products with a certain strength. A connecting column 201 is provided on one side of the shaping layer 200, and a connecting hole 202 is opened in the middle of the shaping layer 200, which penetrates the connecting column 201, and the axial hole 31 is connected to the connecting hole 202. Please refer to Figure 8The connecting column 201 is sleeved with a torsion spring 50, and the conductive hook is sleeved on the connecting shaft 32 through the connecting hole 202. The connecting shaft 32 is fixed to the external connecting component. A straight torsion arm of the torsion spring 50 is stuck in the torsion arm groove 203 provided on the connecting portion 30, and another straight torsion arm is stuck on the external connecting component. The hook arm 20 of the conductive hook is supported and limited to the external connecting component, so that the torsion spring 50 generates torque. When the holding hook portion 10 is pressed downward, the torsion spring 50 further increases the torque, and the conductive hook moves circumferentially around the connecting shaft. When the force is withdrawn, the conductive hook can bounce upward and roughly return to the initial position.

[0059] Of course, the connecting column 201 can also be formed on the connecting portion 30 of the metal body 100 and integrated with the metal body 100 to enhance the firmness and stability of the connecting portion 30. Figure 8 Two or more conductive hooks are installed in the device, which can be connected to the external connection components or the device body through a connecting shaft 32, and adjacent conductive hooks can be connected using double torsion springs. The two torsion springs 50 are connected through their torsion arms, so that the internal structure is compact and the use space is saved; two or two connecting shafts 32 can also be used, and each connecting shaft 32 is provided with one or two conductive hooks, which can be arranged in a row, or in two rows, or in multiple rows.

[0060] Of course, according to the needs of equipment design or use, the torsion arm groove 203 can be located in the shaping layer 200, and the shaping layer 200 is convexly provided with a snap-fit ​​position, and the connection between the snap-fit ​​position and the shaping layer 200 forms the torsion arm groove 203. The snap-fit ​​position and the shaping layer 200 can be integrally formed by an injection molding process, which is simple to process and saves costs. Of course, other connection methods such as gluing can also be used. The snap-fit ​​position can also be located on the metal body 100, which is strong and durable and not easy to deform. There can also be two or more snap-fit ​​positions, and the torsion of the torsion spring 50 can be adjusted according to the needs of use. According to the needs of equipment design or use, the shaping layer 200 can also be provided with two connecting columns 201 located on both sides, and the two connecting holes 202 in the two connecting columns 201 are connected.

[0061] Please refer to Fig. 9, another elastic connection structure of the connecting part 30, connecting shafts 32 are formed on both sides of the connecting part 30 of the metal body 100, and the connecting shaft 32 is integrated with the metal body 100, and the connecting shaft 32 can be made into an integral whole by processing or welding, and the surface of the connecting shaft 32 can be painted, or a relatively thin insulating layer is formed. Of course, the external connecting component can also be an insulating material. The conducting end 40 is located at the connecting part 30 or the hook arm 20, and is set according to design requirements, which will not be introduced one by one here; or, the surface of the connecting part 30 is covered with a plastic layer (not shown), and a connecting shaft is protruding on the plastic layer, and one end of the connecting shaft is installed in a mounting hole (not shown) of an external connecting component and is clearance-fitted. Torsion springs 50 are sleeved on both ends or one end of the connecting shaft 32. A straight torsion arm of the torsion spring 50 is clamped on the connecting part 30, and another straight torsion arm is clamped on the external connecting component. The external connecting component is provided with a corresponding clamping position, so that the conductive hook claw is elastically installed on the external connecting component, and the connecting shaft 32 is insulated and connected to the mounting hole. The connecting shaft 32 can rotate freely. Adjacent conductive hook claws can be fixed together by the connecting shaft 32, so that the movement between the conductive hook claws is synchronized, which is convenient for unified control, so that the equipment works stably and saves installation space. The hook claw arm 20 of the conductive hook claw is supported and limited to the external connecting component, so that the torsion spring 50 generates torque. When the clamping hook part 10 is pressed downward, the torsion spring 50 further increases the torque, and the conductive hook claw moves circumferentially around the connecting shaft 32. When the force is withdrawn, the conductive hook claw can bounce upward and roughly return to the initial position.

[0062] The technical solution of the present invention is that the metal body itself has conductivity, elastic connection mode and the hook part is provided with a reverse stop and abutment surface. The moving part presses the hook part and moves forward along the sliding inclined surface. When the hook part presses or abuts the second circuit access point, the first circuit electrically connected to the metal body and the second circuit access point of the moving part are electrically connected and turned on. When the moving part moves in the opposite direction, the reverse stop and abutment surface engages with the moving part to prevent the moving part from continuing to move, thereby realizing the unidirectional movement function of the conductive claw. The connecting part is connected to the external connecting part by an elastic connection mode. In the process of the moving part pressing the conductive claw and moving in the horizontal direction, the hook part is ensured to always press the moving part, so that the first circuit and the second circuit are stably connected, which is convenient for the movement of the moving part and realizes the corresponding positioning and signal transmission perception functions.
