Description
Technical Field

Background Art
[0002] With the development of science and technology, RFID technology has been widely used, such as in locking devices. When existing bags, bags, boxes, boxes, cabinets, etc. contain confidential items and cash and need to be locked, they usually use padlocks, electronic password locks, etc. In the above-mentioned prior art, each padlock needs to be equipped with a dedicated key to unlock it, and each electronic password lock also needs a unique password key, which is not easy to manage. At the same time, the two can neither send and receive radio frequency signals, nor can they perform remote inspection of the lock's locking state. They can only be checked by macroscopic observation or manually to see whether the padlock or smart lock is in a locked state, which is cumbersome to operate. For example, batches of bags, boxes, cabinets, etc. cannot be checked at the same time, and it takes a long time to check them one by one, which increases the operating cost. Therefore, there is an urgent need for a locking device that uses a batch wireless detection method to detect the locked, unlocked / unlocked and the states between the two. Summary of the invention

[0053] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. 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.
[0054] Please refer to Figures 1 to 3 The present invention provides a locking device. In a first embodiment of the present invention, the locking device includes a radio frequency antenna 1, a first radio frequency conductive part 2, a second radio frequency conductive part 3 and a conductive clamping elastic moving part 4. The first radio frequency conductive part 2 is provided with at least one radio frequency circuit, the second radio frequency conductive part 3 is provided with at least one radio frequency circuit, and the radio frequency circuit includes at least one radio frequency IC chip; and each conductive clamping elastic moving part 4 includes a conductive contact part 41 and a conductive connection end 42. The conductive clamping elastic moving part body includes a conductive structure made of a conductive metal material. The conductive contact part 41 is directly electrically connected to the conductive connection end 42 through the conductive structure. The conductive clamping elastic moving part 4 has an elastic function and is configured with a force-bearing inclined surface 411 at one end. When the force-bearing inclined surface 411 is subjected to an oblique force, the conductive clamping elastic moving part 4 can bounce up, and when the oblique force is withdrawn, the conductive clamping elastic moving part 4 can bounce back to its original position;
[0055] Please refer to Figures 3 to 5 , a first RF circuit is provided in the first RF conductive part 2, which is electrically connected to the first RF IC chip 21, and an access end of the first RF circuit is located on the surface of the first RF conductive part 2, including a first conductive clamping elastic moving part 401 and a second conductive clamping elastic moving part 402, and an RF antenna 1 is electrically connected between two conductive connection ends 42 of the first conductive clamping elastic moving part 401 and the second conductive clamping elastic moving part 402, and an electrical connection is formed when the two conductive contact parts 41 thereof support the two access ends of the first RF circuit, and an external reading device matching the first RF circuit can read the first RF IC chip 21, and the locking device is in an unlocked or unlocked state;
[0056] Please refer to Figures 6 to 8 A second RF circuit is provided in the second RF conductive part 3, which is electrically connected to the second RF IC chip 31. The access end of the second RF circuit is located on the surface of the second RF conductive part 3. When the two force-bearing inclined surfaces 411 of the first conductive clamping elastic moving part 401 and the second conductive clamping elastic moving part 402 are subjected to the oblique force applied by the second RF conductive part 3, the two conductive contact parts 41 are separated from the two access ends of the first RF circuit. When the second RF conductive part 3 slides along the two force-bearing inclined surfaces 411 of the first conductive clamping elastic moving part 401 and the second conductive clamping elastic moving part 402 until its two conductive contact parts 41 support the two access ends of the second RF circuit, the second RF circuit is electrically connected and conducted with the RF antenna 1, and the second RF conductive part 3 is located between the first RF conductive part 2 and the first conductive clamping elastic moving part 401 and the second conductive clamping elastic moving part 402. An external reading device matching the second RF circuit can read the second RF IC chip 31, and the locking device is in a locked state.
[0057] The oblique force refers to the force acting on the force-bearing inclined surface of the conductive clamping elastic moving part 4, which enables it to bounce relative to the first RF conductive part 2, and the bounce is the movement away from the first RF conductive part 2. After the conductive clamping elastic moving part 4 bounces, the second RF conductive part 3 can slide forward along the force-bearing inclined surface 411. After sliding over the force-bearing inclined surface 411, one end of the conductive clamping elastic moving part 4 or the conductive contact part 41 supports the surface of the second RF conductive part 3. The front of the deep end of the second RF conductive part 3 is also an inclined surface, which facilitates the sliding of the second RF conductive part 3 and reduces resistance.
[0058] In the technical solution of the present invention, the conductive clamping elastic moving part 4 connects and disconnects the RF antenna 1 with the circuit in the first RF conductive part 2 or the second RF conductive part 3, and is read separately using a matching external reading and writing device. According to the acquired first RF IC chip 21, it can be determined whether the locking device is in an unlocked or unlocked state; or the information of the second RF IC chip 31 can be obtained to determine whether the locking device is in a locked state. When the locking device is not damaged, the external reading and writing device does not read the information of the first RF IC chip 21 and the second RF IC chip 31, and it can be determined that the locking device is in the process of being locked, thereby realizing the detection of the locking device being in the locked, unlocked / unlocked and states between the two.
[0059] Radio Frequency (RF) is the abbreviation of Radio Frequency, which means the electromagnetic frequency that can be radiated into space, ranging from 300KHz to 300GHz. Radio Frequency is short for RF, which is the abbreviation of radio frequency current, a high-frequency alternating electromagnetic wave. Alternating current that changes less than 1000 times per second is called low-frequency current, and alternating current that changes more than 10,000 times per second is called high-frequency current, and radio frequency is such a high-frequency current. High frequency (greater than 10K); radio frequency (300K-300G) is a higher frequency band of high frequency; microwave frequency band (300M-300G) is a higher frequency band of radio frequency. In electronic theory, when current flows through a conductor, a magnetic field is formed around the conductor; when alternating current passes through a conductor, an alternating electromagnetic field is formed around the conductor, which is called an electromagnetic wave. When the frequency of electromagnetic waves is lower than 100khz, the electromagnetic waves will be absorbed by the ground and cannot form effective transmission. However, when the frequency of electromagnetic waves is higher than 100kHz, the electromagnetic waves can propagate in the air and be reflected by the ionosphere at the outer edge of the atmosphere, forming long-distance transmission capability. We call high-frequency electromagnetic waves with long-distance transmission capability radio frequency; radio frequency technology is widely used in the field of wireless communications.
[0060] The locking device of the present invention adopts RFID radio frequency technology, which includes active RFID radio frequency technology and passive RFID radio frequency technology. In this embodiment, passive RFID radio frequency technology can be used to save electricity, especially for some places where electricity is strictly controlled, such as bank storage, warehouse, etc., in order to prevent fire, passive RFID radio frequency technology is used. Of course, in some embodiments, active RFID radio frequency technology can also be used to increase the signal transmission distance, etc. In the present invention, the radio frequency antenna 1 circuit and the radio frequency IC chip connected to the radio or the circuit board radio frequency IC chip are all matched with each other, and they are not described one by one below.
[0061] Among them, the number of RF circuits provided in the first RF conductive component 2 is one, such as the first RF circuit, or it can be two, or more than two, such as 3, 4, 5, 6, 7, 8, etc.; the number of RF circuits provided in the second RF conductive component 3 is one, such as the second RF circuit, or it can be two, or more than two, such as 3, 4, 5, 6, 7, 8, etc.
[0062] The first RF conductive component 2 and the second RF conductive component 3 can be circuit boards, RFID electronic seals, and parts / structures of various shapes with RF circuits. For example, the first RF conductive component 2 is a circuit board, and the second RF conductive component 3 is an RFID electronic seal. The second RF conductive component 3 is inserted between the first RF conductive component 2 and the conductive clamping elastic moving component 4 to disconnect the first RF circuit and connect the second RF circuit, thereby realizing the process of converting the locking device from an unlocked / unlocked state to a locked state, and finally realizing a locked state.
[0063] The number of RF IC chips is at least two, and can be three or more than three, such as 4, 5, 6, and 7. The number of conductive clamping elastic moving parts 4 is at least two, a first conductive clamping elastic moving part 401 and a second conductive clamping elastic moving part 402. The number of conductive clamping elastic moving parts 4 can be two or more than two, such as 3, 4, 5, 6, 7, 8, 9, 10 or more than 10. Multiple conductive clamping elastic moving parts 4 are elastically mounted on the mounting part 5. Figure 1 Multiple conductive clamping elastic moving parts 4 can be arranged side by side on the mounting part 5, that is, vertically or horizontally, or both, or in an array or cross arrangement, and the number and arrangement method are designed according to needs. The shape and size of the mounting part 5 are designed according to needs, such as round, long strip, plate, square, irregular shape, etc. Figure 1 Only one situation is shown in the figure, the first conductive clamping elastic moving part 401 and the second conductive clamping elastic moving part 402 may not be arranged in parallel, such as there is a certain interval between the first conductive clamping elastic moving part 401 and the second conductive clamping elastic moving part 402, and one or more conductive clamping elastic moving parts 4 are arranged between them to separate them. Since the conductive clamping elastic moving part 4 has an elastic function, it is disconnected from the first RF circuit access end in the first RF conductive part 2, and is connected to the second RF circuit access end in the second RF conductive part 3 to realize the conduction of the locking circuit or the conduction and disconnection of other RF circuits.
[0064] Please refer to Fig. 9 and Fig.10The conductive clamping elastic moving part 4 has an elastic function because one end of the conductive clamping elastic moving part 4 used for connecting with the external connecting part is connected to the mounting part through an elastic structure, such as a compression spring. It can be understood that the conductive clamping elastic moving part 4 can have an elastic function itself, such as a spring. In the process of the locking device forming a locked state, one end of the second RF conductive part 3 slides forward along and presses at least the two force-bearing inclined surfaces 411 of the first conductive clamping elastic moving part 401 and the second conductive clamping elastic moving part 402 until the second RF circuit is turned on. In the process, the first conductive clamping elastic moving part 401 and the second conductive clamping elastic moving part 402 are subjected to the oblique force applied by the second RF conductive part 3 and bounce up, so that the conductive clamping elastic moving part 4 has elastic potential energy or increases the elastic potential energy; when the second RF conductive part When the conductive clamping elastic moving part 3 is separated from the top holding surface of the conductive clamping elastic moving part 4, the oblique force is withdrawn instantly, so that the conductive clamping elastic moving part 4 rebounds to its original position under the action of elastic potential energy or rebounds toward the original position to resist other parts of the surface of the second RF conductive part 3 that block the rebound, such as a concave groove appears at the relative sliding position between the second RF conductive part 3 and the conductive clamping elastic moving part 4, and the conductive clamping elastic moving part 4 and one end of the sliding part further rebound. If the groove is a through hole, the end will pass through the through hole to the original position under the action of elastic force. The relative movement between the second RF conductive part 3 and the conductive clamping elastic moving part 4 can be a linear motion or a curved motion, such as an S-shaped curved motion.
[0065] Among them, the access end provided on the surface of the first RF conductive part 2 and the second RF conductive part 3 can conduct electricity and is used to electrically connect with the circuit in the corresponding RF conductive part. The access end occupies a certain surface area on the surface of the first RF conductive part 2 and the second RF conductive part 3. The surface of the access end is preferably a plane, or it can be a curved surface, which is designed according to the use needs. The access end has a certain length, which can ensure that the circuit is still in a conductive state during the insertion or withdrawal of the second RF conductive part 3 from the insertion space, and different signals are transmitted. The insertion space is the space formed between the first RF conductive part 2 and the conductive clamping elastic moving part 4. The exposed surface of the access end is a conductive contact surface (not marked), and the conductive contact of the access end contacts the conductive clamping elastic moving part 4 to realize the connection and communication of the two circuits. The length of the access end can be greater than 0mm and less than or equal to 200mm, such as 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, mm, 150mm, 160mm, 190mm, etc. Of course, the access end can also be designed to be greater than 200mm.
[0066] in, Figure 1 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 In the figure, the conductive clamping elastic moving part 4 connecting the radio frequency antenna 1 is not shown. Fig. 9 In the figure, the dotted line indicates that the antenna part is omitted, and the line connected to the dotted line is an electric wire, and can also be other connection structures without limitation.
[0067] In the present invention, an antenna is a converter that converts the guided waves propagating on the transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or performs the opposite conversion. A component used to transmit or receive electromagnetic waves in a radio device. Engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., all of which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are reversible, that is, the same pair of antennas can be used as both transmitting antennas and receiving antennas. The basic characteristic parameters of the same antenna as a transmitter or receiver are the same. Antennas are now more and more widely used, anti-interference requirements are becoming more and more stringent, and the types of designs are also diversified. For example, the radio frequency antenna 1 used in RFID electronic seals or tags is widely used in the field of logistics. It can store relevant data of commodities, credit cards, access cards and vehicle control in RF. The radio frequency antenna 1 matches the radio frequency IC chip in the RFID electronic seal, and the RFID reader matching the radio frequency antenna 1 reads the information in the radio frequency IC chip. RFID electronic seals can also be used in locking devices. When the locking device is in a locked state, the radio frequency IC chip can be read. Among them, the ideal antenna does not consider the feeder, but in order to lead out the signal, the lead-out point is called the feeder, which is expressed in English as feedpoint. The addition of the feeder generally affects the field distribution of the antenna, and the selection of this point is also particular. In the present invention, the conductive connection end of the conductive clamping elastic moving part 4 is directly connected to the feeder of the radio frequency antenna 1 or to the circuit of the radio frequency antenna 1.
[0068] A circuit is a conductive loop composed of metal wires and electrical and electronic components. It is called a circuit. When the circuit is connected, it can generate current to work. 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 different electronic components connected. A continuously connected 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 or an access end (called an access end in the present invention). The access end of the circuit refers to the point / end that can connect the circuit. The access end 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 its corresponding circuit. When there is current in the circuit, the circuit will perform corresponding work. The electrical connection in the invention refers to the direct contact of the mechanical structure of the circuit access point to connect the circuits. Electrical connection refers to the direct contact of the mechanical structures at the access points of the circuits, making the circuits connected.
[0069] Further, please refer to Fig.11 At least one sliding groove 32 is recessed on the surface of the second RF conductive component 3, and at least one access end of the second RF conductive component 3 is laid on the inner wall of the sliding groove 32. The conductive contact portion 41 of the first conductive clamping elastic moving part 401 slides along the inner wall of the sliding groove 32.
[0070] Among them, the sliding groove 51 limits the conductive clamping elastic moving part 4, and the sliding groove 32 allows the conductive clamping elastic moving part 4 to slide along the sliding groove 32, that is, it limits the sliding path of the conductive clamping elastic moving part 4 on the second RF conductive part 3, ensuring the accuracy and stability of the electrical connection between the conductive clamping elastic moving part 4 and the access end on the surface of the second RF conductive part 3, and at the same time avoids the locking device from being subjected to external impact and vibration, causing the conductive clamping elastic moving part 4 to slide, thereby separating the conductive clamping elastic moving part 4 from the access end on the surface of the second RF conductive part 3 and affecting the use effect, thereby enhancing the relative position stability of the conductive clamping elastic moving part 4 and the second RF conductive part 3, being able to keep the second RF conductive part 3 locked in place, improving the use performance, and extending the service life of the locking device.
[0071] The second RF conductive member 3 may be provided with a sliding groove 32 on one side, or on two sides (not shown) or more than two sides. The surface of the second RF conductive member 3 is provided with at least two convex ribs 33 arranged at intervals, and the adjacent convex ribs 33 and the second RF conductive member 3 therebetween form a sliding groove 32. At least one access end of the surface of the second RF conductive member 3 is located at the bottom wall or side wall of the sliding groove 32, and the length direction of the access end of the surface of the second RF conductive member 3 is arranged in parallel with the length direction of the convex rib 33, or the width direction of the access end of the surface of the second RF conductive member 3 is arranged in parallel with the length direction of the convex rib 33, or the length direction of the access end of the surface of the second RF conductive member 3 is arranged between the length direction and the width direction of the convex rib 33. The convex rib 33 and the second RF conductive member 3 can be integrally formed or separately provided, and the separately provided convex rib 33 is connected to the surface of the second RF conductive member 3 by welding, gluing, clamping, etc. When the second RF conductive component 3 is provided with multiple sliding grooves 32, the multiple sliding grooves 32 are arranged in parallel. The sliding grooves 32 can be arranged along a straight line or a curve, such as the groove walls of the sliding grooves 32 are arranged to form concentric circles. Some sliding grooves 32 do not have access ends on the surface of the second RF conductive component 3, and some sliding grooves 32 have one, two, or more access ends on the surface of the second RF conductive component 3.
[0072] In some other embodiments, please refer to Fig.12 , the surface of the second RF conductive member 3 may not have a sliding groove, and the access end of the second RF conductive member 3 is directly laid on the surface of the second RF conductive member 3; and / or, please refer to Fig.13 It can be understood that in order to limit and position the second RF conductive member 3, other limiting structures can be provided, such as one end of the second RF conductive member 3 is used to be inserted into the insertion space, and the other end away from the insertion space is provided with a protruding structure 34. During the insertion of the second RF conductive member 3 into the insertion space, when the protruding structure 34 abuts against or approaches the periphery of the opening of the insertion space, the second RF circuit is turned on, and then the locking device is in a locked state. The second RF conductive member 3 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 35, the elastic spine 35 is elastic and bent, and the elastic spine 35 is convex on the surface of the second RF conductive member 3, and one elastic spine 35 is accommodated in one receiving hole, or two elastic spines 35 are accommodated in one receiving hole, or multiple elastic spines 35 are accommodated in one receiving hole. The number of elastic spines 35 can be one, two, or more. When the second RF conductive component 3 is accommodated in or inserted into the insertion space, the elastic spine 35 partially abuts against the first RF conductive component 2 and thus plays the role of a fixed locking device, so that the relative position relationship between the first RF conductive component 2, the second RF conductive component 3 and the conductive clamping elastic moving part 4 is stable. The elasticity of the elastic spine 35 itself is conducive to the relative movement of the two under the action of external force.
[0073] In order to further limit the path for the second RF conductive member 3 to move forward, at least one sliding groove 32 runs through the surface of the second RF conductive member 3 , so that the movement of the second RF conductive member 3 is easy to control.
[0074] Please refer to Fig.14 A plurality of sliding grooves 51 are provided on the surface of the second RF conductive part 3, and a plurality of conductive clamping elastic moving parts 4 are correspondingly provided on the mounting part 5. A conductive contact part 41 of a conductive clamping elastic moving part 4 slides into a sliding groove 51. Of course, in a vertical row, two or more conductive contact parts 41 of a conductive clamping elastic moving part 4 can be provided in a sliding groove 51.
[0075] Furthermore, an access end of the second RF conductive member 3 is connected or separated from a conductive contact portion 41 by a concave-convex locking position, so that the second RF circuit is connected or disconnected from the RF antenna 1 .
[0076] The access end of the second RF conductive part 3 is locked with the conductive contact part of at least two conductive clamping elastic moving parts 4 through a concave-convex clamping position. The two can be separated and locked by the concave-convex clamping position. The conductive clamping elastic moving part 4 has an elastic function to realize that the convex part automatically penetrates into the concave part. The convex end of the conductive clamping elastic moving part 4 can be inserted into the concave end of the second RF conductive part 3 to form a clamping position and lock the connection, or the concave end of the conductive clamping elastic moving part 4 can be locked with the convex end of the second RF conductive part 3 to form a clamping position. The second RF conductive part 3 is locked after being clamped by the conductive clamping elastic moving part 43, and the second RF conductive part 3 is locked in place, and the corresponding RF circuit is turned on.
[0077] When the second RF conductive part 3 is withdrawn or inserted, and the second RF circuit is not turned on, the concave-convex structures of the two parts in the engagement position are separated, and the RF circuit is disconnected. When the second RF circuit is turned on, the concave-convex structures of the two parts in the engagement position are connected, and the RF circuit is turned on. The detachable concave-convex engagement connection ensures that the conductive clamping elastic moving part 4 is connected and disconnected with the circuit in the second RF conductive part 3, and realizes the conversion between the locked state and the unlocked state of the locking device, which is convenient for use. The concave-convex engagement makes the conductive clamping elastic moving part 4 and the second RF conductive part 3 connected stably, and limits the relative movement of the two to lock, further ensuring the stability of the locked state. At the same time, the vibration during the concave-convex engagement can be felt by hand, which improves the user's hand feeling and is convenient for user use. The conductive clamping elastic moving part 4 plays the role of conducting electricity and connecting the circuit. At the same time, when reading the RF IC chip, the conductive clamping elastic moving part 4 can transmit electrical signals. In addition, the conductive clamping elastic moving part 4 has an elastic function to support the second RF conductive part 3 so that the second RF conductive part 3 is tightly connected to the lock body, thereby realizing the locked state of the locking device.
[0078] For details, please refer again to Fig.11 The bottom wall of the sliding groove 32 is concavely provided with at least one limiting snap-fitting groove 36, and the bottom wall of each limiting snap-fitting groove 36 is provided with an access end of a second radio frequency circuit. After a conductive contact portion 41 slides into the limiting snap-fitting groove 36 from the bottom wall of the sliding groove 32, it rebounds toward the bottom wall of the limiting snap-fitting groove 36 to support the access end of the bottom wall of the limiting snap-fitting groove;
[0079] Alternatively, an access end of the second RF circuit is protruded from the bottom wall of the sliding groove 32, and a conductive contact portion 41 of the first conductive clamping elastic moving part 401 is recessed with a through connecting groove. When the conductive contact portion 41 of the first conductive clamping elastic moving part 401 slides along the inner wall of the sliding groove 32 to be electrically connected to the access end of the second RF circuit, an access end of the second RF circuit penetrates into a connecting groove of a conductive contact portion 41 and at least contacts the bottom wall of the connecting groove.

It can be understood that the first conductive clamping elastic moving member 401 and the third conductive clamping elastic moving member 403 may not be in the same row, and the third conductive clamping elastic moving member 403 is arranged behind the first conductive clamping elastic moving member 401, and the second RF conductive member 3 first cooperates with the third conductive clamping elastic moving member 403 to separate the third conductive clamping elastic moving member 403 from the first RF conductive member 2.

[0084] Further, please refer to Fig.11 and Fig.17 The second RF conductive part 3 also includes two penetrating sockets 37. When the two force-bearing inclined surfaces 411 of the two third conductive clamping elastic moving parts 403 are subjected to the oblique force applied by the second RF conductive part 3, the two conductive contact parts 41 of the two second conductive clamping elastic moving parts 402 are separated from the two access ends of the third RF circuit; when the locking device is in the locked state, the two conductive contact parts 41 of the two second conductive clamping elastic moving parts 402 pass through the two sockets 37 and are electrically connected to the two access ends of the third RF circuit.
[0085] In this embodiment, when the information of the second RF IC chip 31 and the third RF IC chip is read by the external reading and writing device matched therewith, the locking device is in the locking state and locked in place. Then, according to the detected second RF circuit and third RF circuit, it can be judged that the locking is in place, and the hand can also feel the dynamic of the conductive contact part of the third conductive clamping elastic moving part 403 passing through the two plug holes 37, and it can be judged from the feeling that the locking is in place, so as to prevent the failure to detect the sealing circuit due to the inaccurate insertion of the second RF conductive part 3.
