Description

Technical Field

[0001] The invention belongs to the technical field of measuring instruments, and in particular relates to a collector which is convenient for wiring. Background Art

[0002] The main function of the collector is to collect signals and data from various sensors or devices. To achieve this function, the collector needs to be connected to the sensor or device through wires to receive the electrical signals output by it. In addition, existing collectors can connect to many wires at the same time to collect data synchronously. In order to adapt to the separate installation of many wires, the collector will be equipped with multi-channel connectors.

[0003] The existing Chinese invention patent with patent number CN114295877A discloses a smart meter collector that prevents false connections and facilitates wiring. The wiring mechanism and positioning pins integrated in the collector are used to achieve the installation of the wire copper nose. The wiring can be positioned and firmly fixed.

[0004] The existing connector of the collector is directly fixed on the circuit board of the collector to achieve a fixed electrical connection. During production, the collector will be fixed to a complete set of distribution boxes and then sent to customers for subsequent self-wiring. The customer will perform wiring after receiving the goods. During this process, the connector is in the distribution box and will be blocked by other components, making wiring inconvenient. During subsequent maintenance and repair, there is a risk of accidentally touching the surrounding wires due to the narrow space when disassembling the wires at the connector. In view of this, a collector that is easy to wire is provided. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a collector that is easy to connect.

[0006] The technical solution adopted to solve the above technical problems is: A collector convenient for wiring, comprising a housing and a collection module, wherein a relay board is provided through the side wall of the housing, the relay board comprises a substrate and pins, plugs are provided at both ends of the pins, one end of the pins is connected to the collection module through a detachable plug connector, and a connector for connecting a wire is detachably installed at the other end of the pins; The connector comprises a housing, a wire insertion hole is provided in the middle of the housing, a pressing member, a first conductive frame and a second conductive frame are installed in the wire insertion hole; The conductive frame 1 includes a horizontally arranged wire carrier, the pressing member is located directly above the wire carrier, a spring is installed at one end of the wire carrier close to the opening of the wire insertion hole, a contact piece 1 is installed at the lower end of the spring, the spring is bent and protruded toward the opening of the wire insertion hole, the spring forms an overhead space between the wire carrier and the contact piece 1, and a flange is formed at the junction of the spring and the wire carrier protruding toward the pressing member; The conductive frame 2 includes a contact sheet 2, and the contact sheet 2 and the contact sheet 1 are located at the same level, and a plug-in gap that matches the pin is formed between the contact sheet 1 and the contact sheet 2.

[0007] During assembly, the relay board is used for expansion to achieve a detachable connection between the acquisition module and the connector. When assembling the wires, the connector can be temporarily taken out of the wiring box for wiring. The operating positions are more diverse, which improves convenience and safety. When wiring, the wire is inserted into the gap between the wire carrier and the clamping piece. After the wire is inserted, the spring is pressed down and deformed. Under the action of the rebound force, the flange will be stuck at the lower edge of the wire, and the clamping piece will temporarily squeeze the wire. Multiple wires can be inserted into the connector at one time, and then the clamping piece can be tightened uniformly with a tool. In addition, the wire carrier clamps the wire and will not cause the wire to fall off when the clamping piece is tightened.

[0008] Furthermore, the conductive frame 1 also includes a support sheet 1, and the conductive frame 2 also includes a support sheet 2. The support sheet 1 and the support sheet 2 extend upward along the inner wall of the wire insertion hole avoiding the opening of the wire insertion hole. The upper parts of the support sheet 1 and the support sheet 2 are horizontally stacked, and a vertical hole that cooperates with the clamping piece is opened at the stacking position of the support sheet 1 and the support sheet 2.

[0009] Through the above technical solution, the design of support piece 1 and support piece 2 extends the wire body from the vertical inner wall and the top inner wall of the wire insertion hole, which can provide more conductive contact surfaces for inserting wires. The clamping piece moves vertically under the guidance of the vertical hole to ensure stable contact at the wiring position.

[0010] Furthermore, the clamping member includes a threading thread, and the support piece 1 and the support piece 2 are provided with threads on the inner wall of the vertical hole, and the threading thread is screwed and assembled with the support piece 1 and the support piece 2 through the threads.

[0011] Through the above technical solution, a thread is opened in the vertical hole, and only one threading member can be used as a clamping member. The threading member can be moved up and down in the wire insertion hole by rotating, and no other components are required, which simplifies the structure of the clamping member and reduces the manufacturing difficulty and cost.

[0012] Furthermore, the clamping member includes a threading thread, and a screw hole frame is installed on the outer side of the threading thread through a threaded connection. The screw hole frame is arranged below the overlapping part of the support piece 1 and the support piece 2, and the screw hole frame is slidably connected with the support piece 1 and the support piece 2 via the vertical hole.

[0013] Through the above technical solution, the screw hole holder is used as a positioning part for threading. The threading can rotate and move up and down in the screw hole holder. When the threading and the screw hole holder are damaged, they can be replaced separately. The first support piece and the second support piece only play a guiding role and have a long service life.

[0014] Furthermore, the pressing member further includes a pressing plate. The wire-carrying piece extends vertically upward at both ends on both sides of the opening of the wire insertion hole in a U-shaped design, and the pressing plate is in sliding contact with the vertical side wall of the wire-carrying piece.

[0015] Through the above technical solution, the threading and the screw hole holder can slide up and down synchronously. After inserting the wire, by pressing the threading, the distance between the pressing plate and the wire-carrying piece can be quickly adjusted to adapt to the temporary pressing work of wires of different sizes. The frictional resistance between the pressing plate and the wire-carrying piece can make the pressing plate stay at the position after being pressed, ensuring the quickness and stability of the temporary wire pressing.

[0016] Furthermore, a card slot is provided on the vertical side wall of the wire-carrying piece facing the pressing plate. The card slot is arranged horizontally up and down. A card tooth is provided on the side of the pressing plate facing the card slot, and the card tooth is arranged horizontally.

[0017] Through the above technical solution, the setting of the card slot can cooperate with the card tooth to increase the frictional force of the contact surface between the wire-carrying piece and the pressing plate, further improving the stability of the pressing. Although it will increase the manufacturing difficulty, it can ensure a greater pressing force and has a significant effect when dealing with the temporary pressing of single-strand copper wires.

[0018] Furthermore, a card slot is provided on the vertical side wall of the wire-carrying piece facing the pressing plate. The card slot is inclined at an angle of 45 degrees relative to the horizontal plane. The extending directions of the card slots on different vertical side walls of the wire-carrying piece are opposite. A card tooth corresponding to the inclined direction of the card slot is provided on the side of the pressing plate facing the card slot.

[0019] Through the above technical solution, through the card slots with opposite inclination angles, the pressing plate can be fixed in a stable position and will not slide horizontally along with the pulling of the wire, avoiding the threading from being bent by force. When connecting wires of multi-strand copper wires, the copper wires scattered by the pressing plate will be squeezed on the vertical plane of the wire-carrying piece, so that the loose multi-strand copper wires can also be more stably pressed to avoid wire detachment.

[0020] Furthermore, the first contact piece and the second contact piece are arranged vertically. The edges of the vertical side walls of the first contact piece and the second contact piece are bent towards each other and abutted. A stepped hole is provided in the middle of the plug, and the vertical inner wall of the stepped hole is in sliding contact with the vertical outer walls of the bent parts of the first contact piece and the second contact piece.

[0021] Through the above technical solution, the cross-sections of the first contact piece and the second contact piece are in a C shape, which can wrap the pin, increasing the conductive contact area. The inner wall of the stepped hole will squeeze and press the front and rear ends of the first contact piece and the second contact piece against the pin, improving the contact stability.

[0022] Furthermore, the edges of the vertical side walls of contact piece 1 and contact piece 2 are bent close to each other and form an inclined end surface, and a guide block is provided on the lower inner wall of the plug opposite to the center line of contact piece 1 and contact piece 2, and the guide block protrudes from top to bottom toward the pin direction.

[0023] Through the above technical scheme, in order to avoid the plugging and unplugging obstruction caused by the stepped hole always squeezing the contact piece 1 and the contact piece 2, a guide block is arranged at the lower part of the plug, which can play the role of squeezing the contact piece 1 and the contact piece 2 from both sides toward the pin direction, and through the mutual squeezing and pushing of the inclined end surfaces, the front and rear ends of the contact piece 1 and the contact piece 2 can also be squeezed and pressed tightly against the pin, and the guide block is arranged at a short distance before the contact piece 1 and the contact piece 2 are inserted into place, which can reduce the plugging and unplugging resistance in most of the stroke.

[0024] Furthermore, the plug connector includes a metal sheet, an encapsulation head is provided at the end of the metal sheet, and the end of the metal sheet is bent 180 degrees to form a buckle strip elastically crimped to the outer wall of the pin.

[0025] Through the above technical solution, after the pins connected to the connector are worn on the front and back sides due to long-term plugging and unplugging, the outer shell can be disassembled, the plug connector can be unplugged, and then the relay board can be swapped left to right, and the pins that are connected to the plug connector and are not worn can be swapped to the connection position with the connector, and the molded pins can be connected to the plug connector. The plug-in buckle strip will produce elastic deformation after being plugged in with the pin, and the contact position is at the left and right sides of the pin where the wear is lighter. This can ensure a stable electrical connection between the plug connector and the relay board after the replacement, reduce the difficulty of repairing the relay board, and increase the service life of the relay board.

[0026] The beneficial effects of the present invention are as follows: (1) The present invention optimizes the relay board and the connector, independently designs the acquisition module and the connector, and performs a detachable electrical connection through the relay board. When connecting the wires and the connector, the connector can be separated from the relay board and moved to an open space to perform wire combing and wiring operations. After completion, the connector connected with the wires can be plugged back into the relay board to be electrically connected to the acquisition module, which has high flexibility in use; (2) The present invention improves the interior of the connector, designs a horizontal wire-carrying sheet in the middle of the conductive frame, and uses a spring sheet to elastically hang the wire. After the wire is inserted, the deformation of the spring sheet is used to temporarily press the wire, so that multiple wires can be elastically crimped at a time. During the wire arrangement process, the position relationship of each wire can be more conveniently disassembled and adjusted, and there is no need to adjust and lock a large number of wires one by one, which simplifies the process. (3) The present invention optimizes the locking member so that the threading of the locking member can be connected to the screw hole frame. The screw hole frame can slide up and down in the wire insertion hole when the threading is relaxed. The internal space of the wire insertion hole can be fully released before wiring. After wiring, the wires of different sizes can be compressed by pressing the threading plate. The pressure plate and the wire carrier are fixed by friction with each other to complete the rapid elastic compression of the wires, making the temporary compression operation of the wires more convenient and quick.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1-Figure 11 As shown, this embodiment provides a collector that is easy to connect. Figure 1 and Figure 3 , including a shell 1 and a collection module 4. The shell 1 is made of insulating material and provides an installation position and wrapping protection. The collection module 4 is the core component of the existing finished line collector, which can collect data such as voltage and current in the line and upload them. When the collection module 4 is connected to the line, it is necessary to use a wire for electrical connection. In addition, the collection module 4 generally collects signals from multiple circuits at the same time, so it will be equipped with a multi-channel connector 2; In actual use, because the connector 2 is mostly fixed at the port position of the acquisition module 4, and then the acquisition module 4 is fixed to the distribution box, a set of distribution boxes is assembled and sent to the customer for use, and the customer performs wiring after receiving the goods. During this process, the connector 2 is in the distribution box, and there will be other components blocking it, which makes wiring inconvenient. In addition, during subsequent maintenance and repair, when disassembling and assembling the wires at the connector 2, there will also be a risk of accidentally touching the surrounding wires due to the narrow space. Therefore, the connection between the connector 2 and the acquisition module 4 is optimized to facilitate the wiring operation during assembly and maintenance; First, refer to Figure 2 The side wall of the housing 1 is penetrated by a relay board 3, which includes a substrate 31 and pins 33. The pins 33 are made of wire material and can transmit current. The substrate 31 is made of insulating material and provides insulation protection for the pins 33. Figure 4 , the substrate 31 is provided with plugs 32 at both ends of the pins 33, and the plugs 32 are located to expose the ends of the pins 33. When in use, one end of the pins 33 is connected to the acquisition module 4 through a detachable plug connector 5, and the other end of the pins 33 is detachably installed with a connector 2 for connecting wires. This detachable connection allows the entire connector 2 to be removed from the relay board 3 when wiring, and the wiring operation can be performed in an open space outside the power distribution cabinet, which is more convenient for operators to comb and fix the wires and can also ensure safety; For connector 2, refer to Figure 5The connector 2 includes a shell 21, which is made of solid insulating material. The bottom of the shell 21 is provided with a slot 22, which can be plugged with the plug 32. After plugging, the inner wall of the slot 22 and the outer wall of the plug 32 slide in contact, which plays a role in protecting the pins 33 from bending and can provide installation space. A wire insertion hole 24 is opened in the middle of the shell 21, and the opening of the wire insertion hole 24 is located on one side of the shell 21, which is convenient for horizontal plugging of wires. Among them, a clamping piece 6, a conductive frame 1 7 and a conductive frame 2 8 are installed in the wire insertion hole 24. The conductive frame 1 7 and the conductive frame 2 8 are fixed parts and are located at the lower part of the wire insertion hole 24. The clamping piece 6 is a movable part and is located at the upper part of the wire insertion hole 24. Before the wire is installed, the clamping piece 6 can be moved upward away from the conductive frame 1 7 and the conductive frame 2 8 to leave sufficient space for the wire to be inserted smoothly. After that, the clamping piece 6 can be moved downward to clamp the wire at the position of the conductive frame 1 7 and the conductive frame 2 8 to complete the fixed electrical connection; Regarding the conductive frame 7, the conductive frame 7 includes a horizontally arranged wire carrier 74, which is horizontally arranged below the pressing member 6 and is in the form of a sheet to increase the contact area with the wire. A spring 72 is installed at one end of the wire carrier 74 near the opening of the wire insertion hole 24. The spring 72 is bent and protruded toward the opening direction of the wire insertion hole 24. The middle part of the spring 72 gradually rises as it goes deeper into the opening of the wire insertion hole 24, which can guide the wire so that the wire is inserted into the top of the wire carrier 74. At the same time, refer to Figure 6 The lower end of the spring piece 72 is provided with a contact piece 71. The spring piece 72 forms an overhead space 25 between the wire carrier piece 74 and the contact piece 71. When wiring, the wire is inserted into the wire insertion hole 24. The spring piece 72 can be deformed downward after the wire is inserted, driving the wire carrier piece 74 downward. In this way, the wire carrier piece 74 can move upward under the rebound force of the spring piece 72, and the wire is pressed between the top surface of the wire carrier piece 74 and the bottom surface of the pressing member 6. The junction of the spring piece 72 and the wire carrier piece 74 protrudes toward the direction of the pressing member 6 to form a flange 73. The flange 73 has a linear protrusion perpendicular to the wire, which can be clamped. At the lower edge of the wire, a temporary elastic limit is performed on the wire, so that the wire can be installed without being locked. After the other wires are plugged in, a unified wire arrangement adjustment is performed, and finally all the clamping members 6 are locked by a screwdriver or an electric screwdriver. During the process, there is no need to bend and arrange multiple wires one by one, use tools to lock, put down the tools to arrange the wires, and then use the tools to lock. The process is simpler and the operation is more convenient. When locking the wire, the spring sheet 72 and the wire carrier sheet 74 will also keep the wire stuck to prevent the wire from being displaced or falling off, and the wiring stability is better. Regarding the conductive frame 28, refer to Figure 6 , the conductive frame 2 8 includes a contact piece 2 81, and the contact piece 2 81 and the contact piece 1 71 are located at the same level. When connecting the relay board 3, refer to Figure 5A plug-in gap that cooperates with the pin 33 is formed between the contact piece 1 71 and the contact piece 2 81. The pin 33 can be inserted into the plug-in gap formed by the contact piece 1 71 and the contact piece 2 81 for wrapped plug-in, thereby improving the plug-in firmness and preventing the connector 2 from falling off the relay board 3 during use.

[0031] In a further embodiment, referring to Figure 6 , the conductive frame 1 7 also includes a support sheet 1 75, and the conductive frame 2 8 also includes a support sheet 2 82. The support sheet 1 75 and the support sheet 2 82 avoid the opening of the wire insertion hole 24 and extend upward along the inner wall of the wire insertion hole 24. The design of the support sheet 1 75 and the support sheet 2 82 extends the wire body from the vertical inner wall and the top inner wall of the wire insertion hole 24, which can provide more conductive contact surfaces for the wire to be inserted, and make more comprehensive contact with the side and top surfaces of the wire. The contact area is large, the resistance is low, and the wiring is more secure. A vertical hole that cooperates with the clamping piece 6 is opened at the stacking position of the support sheet 1 75 and the support sheet 2 82. The clamping piece 6 moves vertically under the guidance of the vertical hole to ensure the contact stability of the wiring position. The upper parts of the support sheet 1 75 and the support sheet 2 82 are horizontally stacked, which can increase the overall thickness of the horizontal position of the support sheet 1 75 and the support sheet 2 82, avoid bending deformation, and improve the stability of the guide.

[0032] In a further embodiment, referring to Figure 5 The clamping member 6 includes a threading wire 61, and the shell 21 is provided with a receiving groove 23 at the position of the threading wire 61. The height of the receiving groove 23 is not lower than the highest position that the threading wire 61 can reach, and the protection effect is good. The space of the receiving groove 23 is much larger than the outer diameter of the threading wire 61, which can facilitate the contact of the tool with the threading wire 61 and the locking operation. The support piece 1 75 and the support piece 2 82 are provided with threads on the inner wall of the vertical hole, and threads are opened in the vertical hole. Only one threading wire 61 can be used as the clamping member 6. The threading wire 61 can be moved up and down in the wire insertion hole 24 by rotating it. No other components are required. The threading wire 61 is screwed and assembled with the support piece 1 75 and the support piece 2 82 through threads. The threading wire 61 can be rotated to complete the locking and release of the wire, simplifying the structure of the clamping member 6 and reducing the manufacturing difficulty and manufacturing cost.

[0033] In a further embodiment, referring to Figure 6 The pressing member 6 includes a threading member 61, and a screw hole frame 62 is installed on the outer side of the threading member 61 through a threaded connection. The screw hole frame 62 is used as a positioning member for the threading member 61, and the threading member 61 can be extended and retracted up and down by rotating in the screw hole frame 62 to compress and relax the wire. At the same time, when the threading member 61 and the screw hole frame 62 are damaged, they can be replaced separately. The screw hole frame 62 is arranged below the stacking of the support piece 1 75 and the support piece 2 82. The screw hole frame 62 is slidably plugged with the support piece 1 75 and the support piece 2 82 via the vertical hole. The support piece 1 75 and the support piece 2 82 only play a guiding role and have a long service life.

[0034] In a further embodiment, referring to Figure 6, the pressing member 6 further includes a pressing plate 63. The wire-carrying piece 74 extends vertically upward at both ends on both sides of the opening of the wire insertion hole 24 and is designed in a U shape. The wire threading 61 and the screw hole holder 62 can slide up and down synchronously. After inserting the wire, the distance between the pressing plate 63 and the wire-carrying piece 74 can be quickly adjusted by pressing the wire threading 61 to adapt to the temporary pressing work of wires of different sizes. The pressing plate 63 is in sliding contact with the vertical side wall of the wire-carrying piece 74. The frictional resistance between the pressing plate 63 and the wire-carrying piece 74 can make the pressing plate 63 stay at the position after being pressed, continuously pressing the wire to ensure the quickness and stability of the temporary wire pressing.

[0035] In a further embodiment, referring to Fig. 9 , a clamping groove 76 is formed in the vertical side wall of the wire-carrying piece 74 facing the pressing plate 63. The clamping groove 76 is arranged horizontally up and down. A clamping tooth 64 is arranged on one side of the pressing plate 63 facing the clamping groove 76. The clamping tooth 64 is arranged horizontally. The setting of the horizontal clamping groove 76 can cooperate with the clamping tooth 64 to increase the frictional force of the contact surface between the wire-carrying piece 74 and the pressing plate 63, further improving the stability of pressing. It should be emphasized that although it will increase the manufacturing difficulty, it can ensure greater pressing force and is not easily pressed and rebound upward. When dealing with the temporary pressing of single-strand copper wires, the pressing force can be increased, and the fixing effect on this cylindrical wire of single-strand copper wire is remarkable.

[0036] In a further embodiment, referring to Fig.10 , a clamping groove 76 is formed in the vertical side wall of the wire-carrying piece 74 facing the pressing plate 63. The clamping groove 76 is inclined at an angle of 45 degrees relative to the horizontal plane. The extending directions of the clamping grooves 76 on different vertical side walls of the wire-carrying piece 74 are opposite. Through the clamping grooves 76 with opposite inclination angles, the pressing plate 63 can be fixed in a stable position, and the pressing plate 63 is limited in the direction of wire insertion and extraction, and will not slide horizontally along with the pulling of the wire, avoiding the wire threading 61 from being bent by force. A clamping tooth 64 corresponding to the inclination direction of the clamping groove 76 is arranged on one side of the pressing plate 63 facing the clamping groove 76. When connecting a wire of multiple-strand copper wires, the copper wires scattered by the pressing plate 63 will be squeezed on the vertical plane of the wire-carrying piece 74, contact with the clamping groove 76, and will also be squeezed, making the wire not easy to move horizontally. In this way, the loose multiple-strand copper wires can also be pressed more stably, avoiding wire detachment, and the applicability is stronger.

[0037] In a further embodiment, referring to Figure 6 , the first contact piece 71 and the second contact piece 81 are arranged vertically. The edges of the vertical side walls of the first contact piece 71 and the second contact piece 81 are bent and close to each other and abut. The cross-sections of the first contact piece 71 and the second contact piece 81 are in a C shape, which can wrap the front and rear side walls of the pin 33, increasing the conductive contact area. When inserting, referring to Figure 7A stepped hole 34 is provided in the middle of the plug 32, and the vertical inner wall of the stepped hole 34 is in sliding contact with the vertical outer wall at the bending point of the contact piece 1 71 and the contact piece 2 81. The inner wall of the stepped hole 34 will press the front and rear ends of the contact piece 1 71 and the contact piece 2 81 against the pin 33 to improve the contact stability and effectively prevent the connector 2 from falling off after being plugged in.

[0038] In a further embodiment, in order to avoid plugging and unplugging obstruction caused by the stepped hole 34 always squeezing the contact piece 1 71 and the contact piece 2 81, refer to Figure 8 The edges of the vertical side walls of the contact piece 1 71 and the contact piece 2 81 are bent close to each other and form an inclined end surface 9. A guide block 35 is provided at the inner wall of the lower part of the plug 32, facing the midline of the contact piece 1 71 and the contact piece 2 81. The guide block 35 is provided at the lower part of the plug 32, which can play a role in squeezing the contact piece 1 71 and the contact piece 2 81 from both sides toward the pin 33, and through the mutual squeezing and pushing of the inclined end surface 9, the front and rear ends of the contact piece 1 71 and the contact piece 2 81 can also be squeezed and pressed against the pin 33. The guide block 35 protrudes from top to bottom toward the pin 33. At the same time, the guide block 35 is provided at a short distance before the contact piece 1 71 and the contact piece 2 81 are inserted into place, and will not contact the contact piece 1 71 and the contact piece 2 81 in the initial and middle stages of insertion, which can reduce the resistance of plugging and unplugging in most strokes, making disassembly and assembly more convenient.

[0039] In a further embodiment, referring to Fig.11 The plug connector 5 includes a metal sheet 52, which is used to conduct current. A sealing head 51 is provided at the end of the metal sheet 52. The sealing head 51 is made of insulating material to protect the metal sheet 52 and provide a hand-holding position for the user when plugging and unplugging. The end of the metal sheet 52 is bent 180 degrees to form a buckle strip 53 that is elastically crimped with the outer wall of the pin 33. After the pin 33 connected to the connector 2 is worn on the front and back sides due to long-term plugging and unplugging, the shell 1 can be disassembled, the plug connector 5 can be unplugged, and then the relay board 3 can be swapped left and right, and the pin 33 that is plugged with the plug connector 5 and is not worn can be swapped to the connection position with the connector 2, and the molded pin 33 can be connected to the plug connector 5. The plug-in buckle strip 53 will produce elastic deformation after being plugged with the pin 33, and the contact position is at the left and right sides of the pin 33 where the wear is lighter, which can ensure that the plug connector 5 and the relay board 3 are stably electrically connected after the replacement, reduce the difficulty of repairing the relay board 3, and increase the service life of the relay board 3.

[0040] The working principle of this embodiment is as follows: During assembly, the relay board 3 is used for expansion to realize the detachable connection between the acquisition module 4 and the connector 2. When assembling the wires, the connector 2 can be temporarily taken out of the distribution box for wiring. When wiring is done outside the distribution box, other wires and distribution components can be avoided. The operation positions are more diverse, which improves convenience and safety. In addition, the relay board 3 can also swap the ends of the connecting plug 5 and the connector 2. After the connector 2 is plugged and unplugged many times and the pins 33 are worn out, they can be swapped and continued to be used without replacement. The maintenance is convenient and the service life of the pins 33 of the wearing parts is long. When wiring, the wire is inserted into the gap between the wire carrier 74 and the clamping member 6. After the wire is inserted, because the spring sheet 72 is a "<"-shaped structure, it will be deformed when the spring sheet 72 is pressed down. Under the action of the spring sheet 72's rebound force, the flange 73 will be pushed up and stuck on the lower edge of the wire, and finally cooperate with the clamping member 6 above to temporarily elastically squeeze the wire, so that multiple wires can be inserted into the connector 2 at one time. When all the wires are cut, bent, compared and stuck in the connector 2, the clamping member 6 is tightened uniformly with a tool for final fixation. Misconnection in the offline process can be quickly adjusted, and the operation process is more simplified. In addition, the wire carrier 74 pressing the wire is a continuous force. In the process of tightening the clamping member 6, the wire will be continuously clamped and not easy to fall off, and the electrical connection after wiring is more stable. When dealing with single-strand wires with higher hardness, because the single-strand wires themselves are not easy to bend and deform, and the contact area between the cylindrical shape and the conductive frame 7 and the clamping member 6 is small, the clamping force of the single-strand wire can be increased by using the clamping teeth 64 of the pressing plate 63 and the clamping groove 76 of the wire carrier 74 to prevent it from falling off after temporary clamping; When dealing with multi-strand copper wire conductors that are easy to disperse, the mutual constraints inside the wires are poor, and they are easy to loosen and move during the pressing process of the pressing plate 63. The slot 76 is set to be inclined, and the copper wire is pressed in the slot 76 position by the pressing plate 63, which can prevent the wire from being easily pulled horizontally and falling off. The slot 76 can also be used to center the threading wire 61 to prevent the threading wire 61 from bending, thereby improving the stability of multiple uses.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
