Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to a continuous intelligent pressure plate. Background Technology

[0002] Power circuit breakers are crucial secondary electrical devices, typically installed in power line system circuits for opening and closing power lines, controlling the on / off state of transmission lines. Integrated intelligent circuit breakers are usually installed on substation control panels. These panels typically have two terminals connecting to the transmission lines, and the panel usually has two corresponding electrical contact holes. The integrated intelligent circuit breaker has two electrodes corresponding to these two electrical contact holes, which are inserted to form a control circuit.

[0003] A multi-piece intelligent pressure plate with remote control function typically consists of a pressure plate body and a deployment / retraction device that drives the pressure plate body. For example, in related technologies, please refer to the structure of a relay protection multi-piece hard pressure plate position sensor disclosed in Chinese Patent Publication No. CN216160783U. Figure 14 The structure includes a fixing member 401, two terminals 402, a contact piece 403, a washer 405, and a locking nut 405. One of the terminals 402 is rotatably mounted on the fixing member 401. The contact piece 403 rotates together with the terminal 402 to make or break contact with the other terminal 402. Two washers 405 are provided at intervals on each terminal 402. The entire structure is locked into the installation environment by the cooperation of the locking nut 405 and the fixing member 401.

[0004] The connection point between this structure and the external power supply is located on two terminals 402. Specifically, the wiring is clamped between two pads 405. With this structure, when maintenance or replacement is required, the entire device needs to be replaced and the original wiring needs to be disconnected, which brings inconvenience to the installation and maintenance work. Summary of the Invention

[0005] The main objective of this invention is to provide a continuous intelligent pressure plate, which aims to improve the ease of disassembly and maintenance of the continuous intelligent pressure plate during its use in power distribution cabinets.

[0006] To achieve the above objectives, the present invention proposes a continuous intelligent pressure plate, which is applied to a power distribution cabinet. The continuous intelligent pressure plate includes an engagement / disengagement device for installation on the inner side of the cabinet panel and a pressure plate body for installation on the outer side of the cabinet panel. The engagement / disengagement device is detachably connected to the pressure plate body and has two terminals for connection to external power wiring. The pressure plate body has a first electrode and a second electrode, which are detachably inserted into the two terminals. The pressure plate body has a conductive connecting piece fixedly connected to the first electrode. The engagement / disengagement device has a driving component for driving the first electrode to rotate. The driving component drives the first electrode to rotate, causing the conductive connecting piece to contact or disconnect from the second electrode.

[0007] In one embodiment of the present invention, the deployment / retraction device includes a housing, an electronic control board, a drive assembly electrically connected to the electronic control board, and two terminals. The electronic control board and the drive assembly are installed inside the housing, and the two terminals are installed inside the housing and exposed outside the housing for connection to an external power source.

[0008] The pressure plate body includes a base, the first electrode and the second electrode are mounted on the base, and the first electrode and the second electrode can be plugged through the housing and respectively inserted into two terminals.

[0009] In one embodiment of the present invention, the box body includes a bottom box and a box cover, the electronic control board and the drive assembly are mounted on the bottom box, and the two terminals are spaced apart on the box cover, wherein the box cover and the bottom box are slidably connected.

[0010] The first electrode and the second electrode are respectively pluggable through the bottom box and inserted into one of the terminals.

[0011] In one embodiment of the present invention, sliding pillars are provided on opposite sides of the bottom box, and sliding grooves are formed on opposite sides of the box cover, with the sliding pillars engaging in the sliding grooves.

[0012] In one embodiment of the present invention, the bottom box includes a bottom plate and a cover covering one end of the bottom plate. Long strip-shaped sliding columns are formed on opposite sides of the bottom plate. The cover and the bottom plate cooperate to form a receiving cavity. The driving component is embedded and fixed in the receiving cavity. The cover has a socket for the first electrode and the second electrode to extend into.

[0013] And / or, the cover includes a top plate and two side plates respectively connected to opposite sides of the top plate, the side plates away from the top plate having the groove formed thereon, the top plate having a stepped surface, and the two terminals mounted on the stepped surface.

[0014] In one embodiment of the present invention, the driving assembly includes a drive motor and a transmission wheel that is drively connected to the drive motor, the transmission wheel having a shaft hole;

[0015] The first electrode can be plugged through the shaft hole and inserted into the terminal block. The insertion / retraction device drives the first electrode to rotate through the shaft hole, and the first electrode further drives the conductive connecting piece to rotate.

[0016] In one embodiment of the present invention, the first electrode includes a conductive segment and a driving segment. The conductive segment passes through the shaft hole and is inserted into the terminal block. The driving segment is circumferentially engaged with the shaft hole so that the transmission wheel drives the first electrode to rotate.

[0017] In one embodiment of the present invention, the transmission wheel includes a first transmission segment and a second transmission segment coaxially arranged. The shaft hole passes through the first transmission segment and the second transmission segment, and the inner diameter of the shaft hole in the first transmission segment is larger than the inner diameter of the shaft hole in the second transmission segment to form a limiting step. The outer diameter of the conductive segment is smaller than the outer diameter of the driving segment to form a limiting part. The limiting part abuts against the limiting step to restrict the first electrode from moving axially.

[0018] In one embodiment of the present invention, the terminal block includes a sleeve, multiple conductive buckles and a conductive ring. The conductive buckles are elongated and extend axially within the inner cavity of the sleeve. The multiple conductive buckles are arranged at intervals along the circumference of the sleeve, and the conductive ring connects the multiple conductive buckles together in series.

[0019] The inner diameter of the conductive ring is smaller than the outer diameter of the first electrode and the second electrode, so that the first electrode and the second electrode are inserted into the inner side of the conductive ring and the plurality of conductive buckles in an interference fit.

[0020] In one embodiment of the present invention, the conductive buckle includes a long strip-shaped rod and a hook connected to the end of the rod, and a plurality of the hooks are hooked onto the conductive ring to support and fix the conductive ring.

[0021] In one embodiment of the present invention, a conductive element is also fixed on the second electrode. The conductive element includes a connecting portion and two elastic arms connected to the connecting portion. The connecting portion is fixedly connected to the second electrode. When the continuous intelligent pressure plate is in the throwing position, the conductive continuous plate is clamped by the two elastic arms.

[0022] In one embodiment of the present invention, the elastic arm includes a support segment, a transition segment, and a guide segment connected in sequence, wherein the guide segment and the transition segment form an angle.

[0023] The spacing between the guide segments on the two elastic arms gradually decreases in the direction toward the transition segment, and the minimum spacing between the two guide segments is less than the thickness of the conductive strip.

[0024] In one embodiment of the present invention, a receiving groove is formed in the base to accommodate the conductive connecting piece and the elastic arm. When the connected intelligent pressure plate is in the deployed position, the conductive connecting piece is received in the receiving groove and locked between the two elastic arms. When the connected intelligent pressure plate is in the retracted position, the conductive connecting piece extends out of the base from the receiving groove.

[0025] In one embodiment of the present invention, the base includes a base body and two connecting cylinders connected to one side of the base body. The first electrode and the second electrode pass through the base body and one of the connecting cylinders, respectively. A threaded connection portion is formed on the connecting cylinder. The pressure plate body passes through the mounting hole on the cabinet plate through the connecting cylinder and is locked to the cabinet plate by a nut.

[0026] The technical solution of this invention divides the continuous intelligent pressure plate into two parts: the pressure plate body and the activation / deactivation device. This allows the pressure plate body and the activation / deactivation device to be installed on the outer and inner sides of the power distribution cabinet, respectively. Furthermore, the first and second electrodes in the pressure plate body are pluggable and inserted into the activation / deactivation device, making electrical contact with the terminal block. The terminal block is fixed to the activation / deactivation device to connect the power supply line. With this structural configuration, during the disassembly and maintenance of the continuous intelligent pressure plate, separating the pressure plate body and the activation / deactivation device simply requires unplugging the activation / deactivation device from the two electrodes. Since the external wiring is located on the terminal block fixed in the activation / deactivation device, the terminal block on the activation / deactivation device and the external wiring can still be retained after removing the pressure plate body, without needing to disassemble the original wiring. Therefore, the entire disassembly and maintenance process is quite convenient. Attached Figure Description

[0049] This invention proposes a continuous intelligent pressure plate 300.

[0050] Please refer to the reference. Figures 1 to 5 In this embodiment of the invention, the continuous intelligent pressure plate 300 is applied to a power distribution cabinet. The continuous intelligent pressure plate 300 includes a deployment and retraction device 100 for installation on the inner side of the cabinet panel of the power distribution cabinet and a pressure plate body 200 for installation on the outer side of the cabinet panel.

[0051] In this embodiment, the deployment / retraction device 100 is detachably connected to the pressure plate body 200. The deployment / retraction device 100 includes a housing 110, an electrical control board 120, a drive assembly 130 electrically connected to the electrical control board 120, and two terminals 180. The electrical control board 120 and the drive assembly 130 are installed inside the housing 110, while the two terminals 180 are installed in the housing 110 and exposed outside for connection to an external circuit. The drive assembly 130 includes a drive motor 150 and a transmission wheel 170 connected to the drive motor 150. The transmission wheel 170 has a shaft hole 173. Specifically, during power connection, the wires of the external circuit can be locked to the exposed portion of the terminals 180 using locking screws.

[0052] The pressure plate body 200 includes a base 210, a first electrode 220, a second electrode 230, and an engagement / disengagement structure (not shown). The first electrode 220 and the second electrode 230 are both installed through the base 210. The engagement / disengagement structure is used to connect and disconnect the first electrode 220 and the second electrode 230. The engagement / disengagement structure is connected to and controlled by the drive assembly 130.

[0053] The first electrode 220 and the second electrode 230 of the present invention can be inserted into the deployment and retraction device 100 and make conductive contact with a terminal 180.

[0054] In this embodiment, the conductive contact between the second electrode 230 and the first electrode 220 and the terminal 180 can be either abutment against the outer wall surface or a nested connection. In short, the conductive contact between the second electrode 230 and the first electrode 220 and the terminal 180 is such that they can be separated without the aid of disassembly tools. In a preferred embodiment, the first electrode 220 and the second electrode 230 are detachably inserted into the two terminals 180.

[0055] Therefore, the technical solution of this invention divides the continuous intelligent pressure plate 300 into two parts: a pressure plate body 200 and a deployment / retraction device 100. This allows the pressure plate body 200 and the deployment / retraction device 100 to be installed on the outer and inner sides of the power distribution cabinet, respectively. Furthermore, the first electrode 220 and the second electrode 230 in the pressure plate body 200 are both pluggable into the deployment / retraction device 100 and make electrical contact with the terminal block 180. The terminal block 180 is fixed to and exposed on the housing 110 of the deployment / retraction device 100, enabling external connection of the power supply line. This structural configuration... In the process of disassembling and maintaining the continuous intelligent pressure plate 300, when separating the pressure plate body 200 and the deployment / retraction device 100, it is only necessary to disconnect the deployment / retraction device 100 from the two electrodes. Since the external wiring position is set on the terminal 180 of the box 110 fixed in the deployment / retraction device 100, the wiring position is exposed. Therefore, after removing the drive component 130 in the deployment / retraction device 100, the terminal 180 on the box 110 and the external connection can still be retained without disassembling the original wiring. Therefore, the entire disassembly and maintenance process is relatively convenient.

[0056] In one embodiment, the deployment / retraction structure includes a conductive element 240 and a conductive connecting piece 250. The conductive connecting piece 250 is fixed to the end of the first electrode 220 away from the deployment / retraction device 100, and the conductive element 240 is fixed to the end of the second electrode 230 away from the deployment / retraction device 100. The drive assembly 130 includes a drive motor 150 and a drive wheel 170 connected to the drive motor 150. The drive wheel 170 has a shaft hole 173. The second electrode 230 can be plugged into the deployment / retraction device 100 and inserted into a terminal 180. The first electrode 220 can be plugged into the deployment / retraction device 100 and partially passes through the shaft hole 173 to be inserted into another terminal 180. The deployment / retraction device 100 drives the first electrode 230 and the conductive connecting piece 250 to rotate relative to the base 210 through the shaft hole 173.

[0057] In this embodiment, the continuous intelligent pressure plate 300 retains the traditional continuous intelligent pressure plate structure with two electrodes. Therefore, during the upgrade and renovation of the power cabinet, there is no need to drill additional holes in the original cabinet. This ensures safety during installation and reduces the difficulty and cost of the renovation. Furthermore, during the disassembly and maintenance of the continuous intelligent pressure plate 300, especially when maintaining the activation / deactivation device 100 as an electrical component, there is no need to adjust the original wiring. Simply disconnect the activation / deactivation device 100 from the two electrodes, making disassembly and maintenance convenient.

[0058] In one embodiment, the housing 110 includes a base box 110a and a cover 110b. An electronic control board 120 and a drive assembly 130 are mounted on the base box 110a. Two terminals 180 are spaced apart on the cover 110b. The cover 110b and the base box 110a are slidably connected. The first electrode 220 and the second electrode 230 are respectively pluggably inserted through the base box 110a and into a terminal 180. In this embodiment, the two terminals 180 are positioned on the cover 110b, and the cover 110b and the base box 110a are interlocked. When it is necessary to disassemble and maintain the continuous intelligent pressure plate 300, the cover 110b can be directly slid off. This simultaneously separates the terminals 180 from the first electrode 220 and the second electrode 230, facilitating the exposure of the core component, the drive assembly 130, in the deployment / retraction device 100 for maintenance.

[0059] Please refer to the reference. Figure 7 and Figure 8 The bottom box 110a has sliding posts 115 on opposite sides, and the top cover 110b has sliding grooves 116 on opposite sides, with the sliding posts 115 engaging in the sliding grooves 116. Specifically, the bottom box 110a includes a bottom plate 111 and a cover 113 covering one end of the bottom plate 111. The bottom plate 111 has elongated sliding posts 115 on opposite sides, and the cover 113 and the bottom plate 111 cooperate to form a receiving cavity 119. The drive assembly 130 is embedded and fixed in the receiving cavity 119, and the cover 113 has insertion holes 117 for the first electrode 220 and the second electrode 230 to extend into.

[0060] The cover 110b includes two side plates 112 and a top plate 114. The top plate 114 is connected to one side of the two side plates 112. The side of the two side plates 112 away from the top plate 114 is formed with a sliding groove 116. The top plate 114 is formed with a stepped surface 118. Two terminals 180 are installed on the stepped surface 118.

[0061] In this embodiment, the base box 110a and the cover 110b can be made of plastic and manufactured by injection molding. In the structure of the base box 110a, the cover 113 includes an arched surrounding plate and an end plate connected to one end of the surrounding plate. The upper part of the end plate has two spaced-apart insertion holes 117 for the insertion of the first electrode 220 and the second electrode 230, respectively. The sliding column 115 can be a flat rod 184 and is set on the side edge of the base plate 111. The length direction of the sliding column 115 is consistent with the length direction of the base plate 111. The sliding groove 116 is set on the inner wall surface of the side plate 112. After assembly, the cover 110b covers the exposed base plate 111 of the base box 110a, thereby forming a relatively sealed box 110. To improve the convenience of the assembly process, this embodiment can form a funnel-shaped guide groove section at the entrance of the slide groove 116. The opening width of the guide groove section is greater than the thickness of the slide column 115, which facilitates the guidance of the slide column 115 during the docking process so that it can be inserted into the slide groove 116.

[0062] Please refer to the reference again. Figures 1 to 3 In one embodiment, the drive assembly 130 includes a housing 140 and a drive motor 150, a transmission assembly 160, and a transmission wheel 170 mounted on the housing 140. The transmission assembly 160 drives the drive motor 150 and the transmission wheel 170. The transmission wheel 170 has a polygonal shaft hole 173. The first electrode 220 includes a conductive section 222 and a drive section 223. The outer diameter of the conductive section 222 is smaller than the diameter of the shaft hole 173. The conductive section 222 passes through the shaft hole 173 and makes conductive contact with the terminal 180. The cross-sectional shape of the drive section 223 is adapted to the opening shape of the shaft hole 173 and is nested in the shaft hole 173.

[0063] Please refer to the reference. Figure 11 In this embodiment, the first electrode 220 includes a first connecting segment 221, a conductive segment 222, and a driving segment 223 connected in sequence. The conductive segment 222 passes through the shaft hole 173 and is inserted into the terminal block 180. The driving segment 223 is circumferentially engaged with the shaft hole 173 so that the transmission wheel 170 drives the first electrode 220 to rotate.

[0064] The cross-sectional shape of the shaft hole 173 formed inside the transmission wheel 170 is exemplarily shown to be quadrilateral. The cross-sectional shape of the drive section 223 is adapted to the opening shape of the shaft hole 173 and is also quadrilateral. It is understood that the opening shape of the shaft hole 173 can also be other shapes, such as hexagonal, "D" shaped, etc. The outer diameter of the conductive section 222 is smaller than the diameter of the shaft hole 173. During the assembly process, the conductive section 222 first passes through the insertion hole 117 on the housing 110 and the hole on the casing 140 in sequence, and then passes through the shaft hole 173 and is inserted into the terminal 180. Subsequently, the drive section 223 is nested in the shaft hole 173. This structural form facilitates the removal and removal of the entire deployment and retraction device 100 from the pressure plate body 200 for disassembly and maintenance.

[0065] Please refer to the reference. Figure 2 and Figure 3 as well as Figure 9 and Figure 10 In one embodiment, the transmission assembly 160 includes a reduction gear set 161 and a driven wheel 162. The reduction gear set 161 is fixed to the motor shaft of the drive motor 150. The outer wall of the driven wheel 162 has meshing teeth 163 that mesh with the reduction gear set 161. The middle part of the driven wheel 162 also has a transmission hole 164 with a polygonal opening. The transmission wheel 170 includes a first transmission section 171 and a second transmission section 172 arranged coaxially. The shaft hole 173 passes through the first transmission section 171 and the second transmission section 172. The inner diameter of the first transmission section 171 is larger than the inner diameter of the second transmission section 172 to form a limiting step 174. The outer diameter of the conductive section 222 is smaller than the outer diameter of the driving section 223 to form a limiting part 224 at the connection between the two. The limiting part 224 abuts against the limiting step 174 to limit the axial movement of the first electrode 220.

[0066] By cooperating with the limiting part 224 and the limiting step 174, the first motor 220 is inserted into the deployment and retraction device 100. The limiting cooperation of the limiting part 224 and the limiting step 174 can form feedback that the insertion is in place, so as to avoid the situation where the installation is not in place or the insertion depth is too deep during assembly, which would result in poor power connection with the terminal 180.

[0067] In this embodiment, the outer diameter of the second transmission segment 172 is smaller than that of the first transmission segment 171. The second transmission segment 172 is inserted into the transmission hole 164, and the outer contour shape of the second transmission segment 172 is adapted to the opening shape of the transmission hole 164. This structural form allows the transmission wheel 170 and the driven wheel 162 to be assembled by a plug-in connection, making installation more convenient. Furthermore, the difference in outer diameter between the second transmission segment 172 and the first transmission segment 171 also facilitates the positioning of the transmission wheel 170 and the driven wheel 162 during the installation process.

[0068] Understandably, in other configurations, the outer diameters of the second transmission section 172 and the first transmission section 171 can be the same, and their cross-sectional shapes can be the same. In addition to the plug-in connection mentioned above, the transmission connection between the transmission wheel 170 and the driven wheel 162 can also be gear meshing, belt drive, chain drive, and other forms.

[0069] In this embodiment, the cross-sectional shape of the second transmission segment 172 is exemplarily shown as a quadrilateral, and the opening shape of the transmission hole 164 is also quadrilateral. This configuration ensures structural stability during transmission. It is understood that the cross-sectional shape of the second transmission segment 172 and the opening shape of the transmission hole 164 can also be other shapes, such as pentagons, hexagons, or D-shapes. This embodiment also sets the transmission connection between the transmission component 160 and the transmission wheel 170 as a gear connection, which provides a stable and precise driving structure. It is understood that in other embodiments, the transmission connection between the transmission component 160 and the transmission wheel 170 can also be a surface friction roller drive, a synchronous pulley drive, a synchronous belt drive, or other similar forms.

[0070] To ensure the stability of the conductive contact between the first electrode 220 and the second electrode 230 and the terminal 180, the present invention preferably uses a nested insertion form between the first electrode 220 and the second electrode 230 and the terminal 180. In one embodiment, the second electrode 230 includes a second connecting section 231 and a connecting section 232, both of which are cylindrical. The terminal 180 includes a sleeve 181, multiple conductive buckles 182, and a conductive ring 183. The conductive buckles 182 are elongated and extend axially within the inner cavity of the sleeve 181. The multiple conductive buckles 182 are arranged at intervals along the circumference of the sleeve 181. The conductive ring 183 is embedded at the entrance of the inner cavity of the sleeve 181 and connects the multiple conductive buckles 182 together. In this embodiment, the inner diameter of the conductive ring 183 is smaller than the outer diameter of the conductive segment 222 in the first electrode 220 and the contact segment 232 in the second electrode 230, so that the first electrode 220 and the second electrode 230 are inserted into the inner side of the conductive ring 183 and the multiple conductive clips 182 in an interference fit. The above-described structure of the terminal 180 in this embodiment ensures that the first electrode 220 and the second electrode 230 are not easily detached after being connected to the terminal 180, and that there are multiple conductive contact points, resulting in good conductivity.

[0071] Furthermore, the conductive buckle 182 includes an elongated rod 184 and a hook 185 connected to the end of the rod 184. The hook 185 abuts against the inner wall of the inner cavity of the sleeve 181, and the hooks 185 of multiple conductive buckles 182 are hooked onto the conductive ring 183 to support and fix the conductive ring 183. In one structural form, a buckle groove can be formed at the end of the sleeve 181, and the hook 185 abuts against the groove wall. This arrangement makes it less likely for the conductive buckle 182 to loosen, resulting in a stable structure. At the same time, the hook 185 provides a guiding effect during the insertion of the first electrode 220 and the second electrode 230 through its arc-shaped outer wall surface, making assembly more convenient. To ensure better conductivity, both the conductive buckle 182 and the conductive ring 183 can be made of copper. This design also allows the conductive buckle 182 and the conductive ring 183 to deform during the insertion of the first electrode 220 and the second electrode 230, thereby clamping the first electrode 220 and the second electrode 230 and ensuring a firm connection.

[0072] The above content mainly describes the throwing and unloading device 100 in detail. The following content will elaborate on the contents of the pressure plate body 200.

[0073] Please refer to the reference. Figure 1 and Figure 2 as well as Figure 6 and Figure 13 In one embodiment, the base 210 includes a base body 211 and two connecting cylinders 212 connected to one side of the base body 211. The first electrode 220 and the second electrode 230 pass through the base body 211 and one connecting cylinder 212, respectively. Threaded connections are formed on the connecting cylinders 212. The pressure plate body 200 passes through the connecting cylinders 212 through mounting holes in the cabinet panel and is locked to the cabinet panel with nuts. This structural design ensures a stable connection structure after the pressure plate body 200 is installed, and also facilitates assembly and disassembly.

[0074] In this embodiment, the second connecting segment 231 of the second electrode 230 has connecting threads. During installation, the second connecting segment 231 is fixed in the countersunk hole on the base 211 by a nut. A handle is installed on the first connecting segment 221 of the first electrode 220, and the handle is locked to the end of the first connecting segment 221 by a screw.

[0075] The conductive element 240 includes a connecting portion 241 and two elastic arms 242 connected to the connecting portion 241. The connecting portion 241 is fixedly connected to the second electrode 220. When the continuous intelligent pressure plate 300 is in the throwing position, the conductive continuous piece 250 is clamped by the two elastic arms 242. In this embodiment, the connecting portion 241 is provided with a through hole to be fixedly sleeved on the fixed second connecting section 231, and the structure of the conductive element 240 being clamped by the elastic arms 242 is beneficial to the stability of the conductive element 240 during electrical connection.

[0076] Furthermore, the elastic arm 242 includes a support section 243, a transition section 244, and a guide section 245 connected in sequence, with the guide section 245 and the transition section 244 forming an angle. The distance between the guide sections 245 on the two elastic arms 242 gradually decreases in the direction towards the transition section 244, and the minimum distance between the two guide sections 245 is less than the thickness of the conductive connecting piece 250. In this embodiment, the elastic arm 242 and the connecting part can be an integral structure, and the support section 243, transition section 244, and guide section 245 in the elastic arm 242 are also integral structures and are thin plates. By forming a guiding structure in the above-mentioned structure of the two elastic arms 242, the conductive connecting piece 250 is more easily engaged between the elastic arms 242 during the switching of the continuous intelligent pressure plate 300 to the positioning process, and is less prone to loosening.

[0077] In one embodiment, a receiving groove 213 is formed in the base 210. The receiving groove 213 extends to the first electrode 220 and is used to accommodate the conductive connecting piece 250. Two elastic arms 242 are embedded in the receiving groove 213. When the connected intelligent pressure plate 300 is in the deployed position, the conductive connecting piece 250 is received in the receiving groove 213 and engaged between the two elastic arms 242 (see reference). Figure 4 When the conductive connecting piece 250 is in the retracted position of the integrated intelligent pressure plate 300, it extends out of the base 210 from the storage groove 213 (see reference). Figure 5 ).

[0078] In this embodiment, the connection between the conductive connecting piece 250 and the conductive component 240 is hidden by the storage groove 213. This minimizes the possibility of external interference when the connected intelligent pressure plate 300 is in the insertion position, and prevents the conductive connecting piece 250 from becoming loose during insertion.
