[0002] When a device with a circuit needs to be electrically connected to a circuit in an external component, it often uses connection methods similar to connectors such as electrical plugging and electrical socketing, and can only achieve the connection of fixed circuits, and cannot achieve that a circuit in the device can be electrically 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, and can only realize functions such as reading and writing identification through their own circuits. The device uses one or more switches to achieve the connection of one or more circuits, and then realizes the transmission of electrical signals and / or communication signals of the device.

[0019] Preferably, the hook body is generally flat or columnar;

[0020] And / or, the hook arm includes a horizontally connecting section and a lifting section connected to each other. The upper surface of the horizontally connecting section is a horizontal plane or is substantially arranged as a horizontal plane. The distance dimension from the upper surface of the lifting section to the horizontal plane gradually increases substantially along the direction of the connecting section towards the hook portion.

[0021] Preferably, the sliding inclined surface and the surface of the adjacent hook arm are substantially arranged in a V shape or a U shape, and / or, the intersection of the sliding inclined surface and the surface of the adjacent hook arm is a curved surface;

[0022] And / or, the reverse anti-retreat abutting surface is smoothly connected to the surface of the hook arm, so that the inner wall of the hook groove is smooth.

[0023] Preferably, the sliding inclined surface is a plane, or the sliding inclined surface is a curved surface;

[0029] The technical solution of the present invention realizes the electrical connection between the first circuit electrically connected to the conduction end and the second circuit access point of the moving member through the conductivity of the hook body itself, the elastic connection method, and the reverse anti-retreat abutting surface provided on the hook portion. When the moving member presses the hook portion and moves forward along the sliding inclined surface, when the hook portion abuts or contacts the second circuit access point, it is electrically connected and conducts. When the moving member moves in the reverse direction, the reverse anti-retreat abutting surface engages with the moving member to prevent the moving member from continuing to move, realizing the one-way movement function of the conductive hook. The connecting portion is connected to the external connecting member through an elastic connection method. During the process of the moving member pressing the conductive hook and moving in the horizontal direction, it ensures that the hook portion always abuts the moving member, enabling the stable connection between the first circuit and the second circuit, facilitating the movement of the moving member, and realizing the corresponding positioning and signal transmission sensing functions.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0046] A circuit is a conductive loop composed of metal wires and electrical and electronic components, and is called a circuit. When the circuit is connected, current is generated and it can work. The circuit can work by applying an external power supply, or it can also work by generating current through RFID radio frequency identification technology. Generally, a circuit is controlled by a switch to work, but for a device with one or more disconnected circuits, when it needs to be connected to one or more external circuits to work, it can be achieved by one or more conductive claws of the present invention.

[0047] Please refer in combination to Figure 1 and Figure 2The conductive hook of the present invention comprises a hook body 100, which comprises 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 and is provided with a conductive contact on the surface. The hook body 100 is also provided with a conducting end, the conducting end 40 is electrically connected to an access point of the first circuit, and the conductive contact is electrically connected to the conducting end 40 through the hook body 100. The surface of the hook body 100 is partially or completely covered with a plastic material shaping layer. The connecting portion 30 is located at the other end of the hook arm 20, and the connecting portion 30 is connected to an external connecting component by an elastic connection method, and a connecting shaft is constructed at the connection point.

[0048] The hook portion 10 is constructed with a sliding inclined surface 11 and a reverse stop-retract abutting surface 12 which are arranged in opposite directions. The sliding inclined surface 11 is arranged away from the hook arm 20, and the reverse stop-retract abutting surface 12 is arranged facing the hook arm 20. The reverse stop-retract abutting surface 12 and the surface of the hook arm 20 adjacent thereto form a hook groove 121.

[0049] When the conductive hook is installed on the external connection component, the sliding inclined surface 11 and its orthographic projection on the horizontal plane are set at an acute angle, and the reverse stop holding surface 12 coincides with its orthographic projection on the horizontal plane or is set at an acute angle;

[0050] When the sliding inclined surface 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 removed, the conductive hook can bounce upward.

[0051] Wherein, a moving part includes a second circuit, an access point of the second circuit is located on the surface of the moving part, and during the process that the moving part has a side provided with the second circuit access point pressing or abutting against the conductive hook claw and moves in the horizontal direction, after the front end of the moving part slides over the sliding inclined surface 11, the hook portion 10 presses or abuts against the moving part, and when the conductive contact touches the second circuit access point, the conductive hook claw electrically connects the first circuit and the second circuit at both ends of the moving part;

[0052] When the moving part moves in the reverse direction, that is, in the direction opposite to the forward direction, the reverse stop abutting surface 12 is abutted by the horizontal force, thereby preventing the moving part from continuing to move.

[0053] The technical solution of the present invention enables the hook body to have conductivity through the electrical connection between the conductive contact and the conduction end, the elastic connection mode of the connecting part, and the reverse anti-retreat abutting surface 12 provided on the hook part 10. The moving part presses the hook part 10 and moves forward along the sliding inclined surface 11. When the hook part 10 abuts or contacts the second circuit access point to connect the conductive contact with the second circuit access point, the first circuit electrically connected to the hook body 100 is electrically connected and conducted with the second circuit access point of the moving part. When the moving part moves in the reverse direction, the reverse anti-retreat abutting surface 12 engages with the moving part to prevent the moving part from continuing to move, realizing the one-way movement function of the conductive hook. The connecting part 30 is connected to the external connecting component through an elastic connection mode. During the process that the moving part presses the conductive hook and moves in the horizontal direction, it is ensured that the hook part 10 always abuts the moving part, enabling the stable connection between the first circuit and the second circuit, facilitating the movement of the moving part, realizing the corresponding positioning and signal transmission sensing functions, and at the same time increasing the movement touch feeling of the hand that pushes the moving part, with flexible control and convenient operation.

[0054] Among them, the surface of the hook part 10 is paved with conductive contacts, that is, the conductive contacts can conduct electricity. The surface of the hook part 10 can be entirely paved with conductive contacts, or the upper surface of the hook part 10 can be paved with conductive contacts, or a partial area of the upper surface of the hook part 10 can be provided with conductive contacts. The conductive contacts are used to connect the second circuit. Therefore, the conductive contacts can be formed by plating metal on the surface of the hook part 10, or metal sheets or metal blocks can be embedded in the hook part. The metal is a conductive metal, and the metal includes silver, copper, aluminum, iron, tungsten, and alloys, etc.

[0055] Please refer to Figure 1 and Figure 2 , the conduction end 40 is made of a conductive material such as metal, etc. The conduction end 40 can be formed by plating metal on the surface of the hook part, or metal sheets or metal blocks can be embedded or protruded on the hook body 100. The metal is a conductive metal. The conduction end 40 has various design structures. One structural design is, please refer to Figure 1 , the conduction end 40 is a protrusion protruding from the connecting part 30. A groove is also provided at the free end of the conduction end 40 to facilitate the connection with the access point of the first circuit. Generally, the wire of the circuit is electrically connected to the conduction end 40 by welding. The groove provided on the conduction end 40 connects the access point of the first circuit and at the same time plays a role in protecting the connection end to prevent damage caused by external contact. The conduction end 40 is provided on the connecting part 30, making the overall structure of the conductive hook beautiful and compact, and at the same time enhancing the strength of the connecting part 30, facilitating the elastic movement of the conductive hook to prevent contact with other structures. Therefore, the conduction end 40 is arranged in the elastic movement direction of the conductive hook;

[0056] Please refer to Figure 3 and Figure 4Another position change design of the conducting end 40 is that the conducting end 40 can protrude from the hook claw arm 20, and the conducting end 40 can be a long, oval, circular or other protrusion; another design method of the conducting end 40 is that the conducting end 40 can also be a groove recessed in the hook claw body 100, and the conducting end 40 is located on the inner wall of the groove; or the conducting end 40 is laid on the surface of the hook claw body 100, and the area occupied by the conducting end 40 is determined according to specific design needs.

[0057] In the above design of the conducting end 40, the conducting end 40 is electrically connected to the surface with the conductive contact through a metal material such as a wire, a metal wire, a metal strip, or a metal block. Figure 1 The dotted lines are used to illustrate, and other situations are not shown. That is, the conducting end 40 and the surface with the conductive contact can be set as one piece, or can be connected together by welding or the like, and then the hook body 100 is shaped and protected by wrapping the corresponding plastic shaping layer on the outside. In order to increase the strength of the hook body 100, the volume of the internal conductive metal can be appropriately increased. The specific structure is determined according to the design requirements, as long as it can achieve the corresponding function.

[0058] 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.

[0059] 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 and the reverse stop and hold surface 12 are subjected to a horizontal force, and the relative position relationship between the three remains roughly unchanged, that is, the conductive hook can be installed and set in any space.

[0060] Among them, the closed loop formed by the first circuit and the second circuit includes a radio frequency IC chip and a radio frequency antenna. The radio frequency IC chip is located in the first circuit, and the radio frequency antenna board is located in the second circuit, or the radio frequency IC chip is located in the second circuit, and the radio frequency antenna board is located in the first circuit; or the radio frequency IC chip and the radio frequency antenna board are located in the first circuit, or the radio frequency IC chip and the radio frequency antenna board are located in the second circuit. When the first circuit and the second circuit are conducted through a conductive hook, the radio frequency IC chip can be read by the outside world. Of course, one conductive hook, or two conductive hooks, or more conductive hooks can be provided in the first circuit and the second circuit. Multiple conductive hooks can be connected simultaneously, or they can be conducted out of sync. For example, when the first circuit and the second circuit are conducted through a conductive hook, the radio frequency IC chip can be read by the outside world. Of course, the first circuit and the second circuit include a first conductive hook and a second conductive hook. When the moving part slides to the first preset distance, the first conductive hook and the second conductive hook are conducted with 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 respectively connected to the two access points of the first circuit and the second circuit; For example 2, the first circuit and the second circuit include a first conductive hook, a second conductive hook, a third conductive hook and a fourth conductive hook. The first circuit is disconnected into two connecting circuits. The first conductive hook, the second conductive hook, the third conductive hook and the fourth conductive hook included in the first circuit and the second circuit are respectively electrically connected to the four access points of the first circuit. When the moving part slides to the first preset distance, the first conductive hook and the second conductive hook are conducted with 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 conducted with two access points of the second circuit.

[0061] It can be understood that in a device, multiple conductive hooks can be provided, connecting multiple circuits. Two or more circuits can be provided in the moving part. When the moving part slides to different preset distances, one or two devices and the circuits in the moving part are connected through the conductive hooks to realize the positioning and sensing function, that is, according to the different components provided in the circuit, the corresponding functions are realized.

[0062] Please refer to Figure 1 and Figure 2, Further, the sliding inclined surface 11 intersects with the reverse anti-retreat abutting surface 12 to form an intersecting free end 122. When the conductive hook is installed on an external connecting component, the highest points of both the sliding inclined surface 11 and the reverse anti-retreat abutting surface 12 are located at the free end 122. The outer surface of the free end has a conductive contact. After the front end of the moving part slides over the sliding inclined surface 11, the surface of the free end 122 with the conductive contact abuts or contacts the moving part. The surface of the free end 122 is a smooth curved surface, and the curved surface includes a circular curved surface, an arc-shaped curved surface, and an elliptical curved surface. Reducing friction is beneficial for sliding, and the curved surface enables the free end 122 to fully contact the moving part during the sliding process. The sliding inclined surface 11 can be a plane, and the sliding inclined surface 11 can also be a curved surface. The curved surface is beneficial for guiding the moving part and increasing the guiding acceleration.

[0063] There can be other connection methods between the top end of the sliding inclined surface 11 of the hook part 10 and the reverse anti-retreat abutting surface 12, that is, as long as the corresponding functions can be achieved. For example, the top end of the sliding inclined surface 11 and the top end of the reverse anti-retreat abutting surface 12 are also connected through a contact surface. The contact surface is used to abut or contact the moving part. The contact surface (not shown) is arranged as a plane or approximately a plane, so that the first circuit and the second circuit are electrically connected or conducted; or the sliding inclined surface 11 intersects with the reverse anti-retreat abutting surface 12 to form a straight line or a curve.

[0064] Further, the conductive hook is connected to the external connecting component through an elastic connection method. During the movement of the moving part, it can move within a limited range. The elastic action of the conductive hook ensures the connection between the hook part 10 of the conductive hook and the moving part. If the conductive hook is fixedly connected to the external connecting component, when the moving part disengages from the hook part 10, the hook part 10 cannot move up and down to abut against the moving part, resulting in the interruption of the circuit connection. The external connecting component can be the main body of the device, a plate-shaped mounting part, or a mounting part of other shapes.

[0065] Please refer to Figure 1 and Figure 2, Further, the hook body 100 is generally flat or columnar, or in other shapes, such as the lower end of the hook body 100 is square; 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 one end of the lifting section 21 away from the horizontal connecting section 22, and the connecting portion 30 is located at one 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 substantially a horizontal plane. The distance dimension from the upper surface of the lifting section 21 to the horizontal plane gradually increases generally along the direction of the lifting section 21 towards the hook portion 10. The lifting section 21 increases the height of the hook portion 10 and also increases the range of the up-and-down elastic movement. There is no specific requirement for the shapes of the lower ends of the lifting section 21 and the horizontal connecting section 22, and the thickness and structural design can be increased according to design and use needs. Of course, the hook body 100 can also be in an irregular shape, and the length and thickness are designed according to specific needs.

[0066] Further, the sliding inclined surface 11 and the surface of the adjacent lifting section 21 are generally arranged in a V or U shape, saving materials and thus reducing costs, occupying a small space, and / or the intersection of the sliding inclined surface 11 and the surface of the adjacent lifting section 21 is a curved surface; and / or, the reverse anti-retreat abutting surface 12 is smoothly connected to the surface of the lifting section 21, making the inner wall of the hook groove 121 smooth, enhancing the guiding effect and reducing the friction force. When the bottom ends of the lifting section 21 and the horizontal connecting section 22 have various shapes, the thickness and width can be set arbitrarily without affecting the use.

[0067] Please refer to Figures 3 to 7 , Further, in one design of the connecting portion 30, a metal ring or semi-ring is provided inside the connecting portion 30, and the surface of the ring or semi-ring is covered with an insulating shaping layer 200. The connecting portion 30 is integrally or separately provided with a metal and a conduction end inside. The metal provided inside the connecting portion 30 enhances the strength of the connecting portion 30. An axial hole 31 is provided in the middle of the ring or semi-ring. The axial hole 31 in the ring is a closed axial hole 31, and the axial hole 31 in the semi-ring is an open semi-circular axial hole 31. The shaping layer 200 covers the surface of the ring or semi-ring. The ring or semi-ring has a certain supporting effect and is also convenient for the shaping and hole opening of the shaping layer 200. The shaping layer (not shown) on the surfaces of the hook arm 20 and the hook portion 10 can be integrally or separately provided with the shaping layer 200 on the surface of the connecting portion 30, which is convenient for the formation of the specific structure. The material of the shaping layer is a plastic material. Of course, it can also be other insulating layer materials, such as urea formaldehyde resin, aniline formaldehyde resin, melamine formaldehyde resin, glycerol resin, silk, cotton yarn, cotton cloth, and their mixed products with a certain strength. Figure 7 As shown, a connecting column 201 is provided on one side of the shaping layer 200, and a connecting hole 202 penetrating the connecting column 201 is provided in the middle of the shaping layer 200. The axial hole 31 communicates with the connecting hole 202. Of course, connecting columns 201 can be provided on both sides of the shaping layer 200.

[0068] Understandably, another design of the connecting part 30 is that the connecting part 30 is entirely constructed by the shaping layer, which can be integrally or separately arranged with the shaping layer 200 on the surface of the connecting part 30.

[0069] Please refer to Figure 8 , a torsion spring 50 is sleeved on the connecting column 201, the conductive hook is sleeved on the connecting shaft 32 through the connecting hole 202, the connecting shaft 32 is installed and fixed on an external connecting component, one torsion arm of the torsion spring 50 is stuck in the torsion arm groove 203 provided on the connecting part 30, and the other torsion arm is stuck on the external connecting component. The hook arm 20 of the conductive hook abuts against and is limited by the external connecting component, so that the torsion spring 50 generates torsion force. When the clamping hook part 10 is pressed downwards, the torsion spring 50 further increases the torsion force, and the conductive hook makes a circumferential movement around the connecting shaft. When the acting force is removed, the conductive hook can bounce upwards and roughly return to the initial position.

[0070] Two or more conductive hooks are installed in the device, which can be connected and installed on an external connecting component or the device main body through a connecting shaft 32, and adjacent conductive hooks can be connected by double torsion springs. The two torsion springs 50 are connected by their torsion arms, making the internal structure compact and saving space; or two or more connecting shafts 32 can be used, and one or two conductive hooks are sleeved on each connecting shaft 32, which can be arranged side by side in a row, or can be formed into two rows, or multiple rows for installation.

[0071] Certainly, according to the design or use requirements of the device, the torsion arm groove 203 is located in the shaping layer 200, and the shaping layer 200 protrudes with a clamping position. The connection between the clamping position and the shaping layer 200 encloses the torsion arm groove 203. The clamping position and the shaping layer 200 can be integrally formed by an injection molding process, which is simple in processing and saves costs. Of course, other connection methods such as gluing can also be used. The clamping position can also be located on the internal metal of the connecting part 30 and protrude from the surface of the shaping layer, which is strong and durable and not easy to deform. The clamping position can also have two or more, and the torsion force of the torsion spring 50 can be adjusted according to the use requirements. According to the design or use requirements of the device, the shaping layer 200 can also be provided with two connecting columns 201 located on both sides respectively, and the two connecting holes 202 in the two connecting columns 201 are communicated with each other.

[0072] Please refer to Figure 9, Another elastic connection structure of the connecting part 30. Connecting shafts 32 are formed on both sides of the connecting part 30, and the connecting shafts 32 and the metal inside the connecting part 30 are integrated. The connecting shafts 32 can be made integrated with the metal inside the connecting part 30 through processing or welding, etc. The surface of the connecting shafts 32 can be painted or have a relatively thin insulating layer. Of course, the external connecting components can also be made of insulating materials. The conducting end 40 is located in 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 connecting shafts 32 are formed in the shaping layer 200, and the shaping layer 200 is penetrated by the connecting shafts 32. One end of the connecting shaft 32 is installed in an installation hole (not shown) of an external connecting component and has a clearance fit. A torsion spring 50 is sleeved on both ends or one end of the connecting shaft 32. One straight torsion arm of the torsion spring 50 is stuck on the connecting part 30, and the other straight torsion arm is stuck on the external connecting component. Corresponding positions are provided on the external connecting component, so that the conductive hook is elastically installed on the external connecting component, and the connecting shaft 32 is insulated from the installation hole. The connecting shaft 32 can rotate freely. Adjacent conductive hooks can be fixed together through the connecting shaft 32, so that the movements of the conductive hooks are synchronized, which is convenient for unified control, makes the equipment work stably, and saves installation space. The hook arm 20 of the conductive hook abuts against and is limited by the external connecting component, so that the torsion spring 50 generates a torsion force. When the clamping hook part 10 is pressed downwards, the torsion spring 50 further increases the torsion force, and the conductive hook makes a circumferential movement around the connecting shaft 32. When the acting force is removed, the conductive hook can bounce upwards and roughly return to the initial position.

[0073] The technical solution of the present invention has the conductive hook body itself with conductivity, an elastic connection method, and a reverse anti-retreat abutting surface provided on the clamping hook part. The moving part presses the clamping hook part and moves forward along the sliding inclined surface. When the clamping hook part abuts against or contacts the second circuit access point, the first circuit electrically connected to the conducting end is electrically connected to the second circuit access point of the moving part to be conducted. When the moving part moves in the reverse direction, the reverse anti-retreat abutting surface engages with the moving part to prevent the moving part from continuing to move, realizing the one-way movement function of the conductive hook. The connecting part is connected to the external connecting component through an elastic connection method. During the process that the moving part presses the conductive hook and moves in the horizontal direction, it is ensured that the clamping hook part always abuts against 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 sensing functions.

[0074] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
