Description

Technical Field

[0001] The present invention relates to the technical field of electrical components, and particularly relates to a detachable terminal block. Background Art

[0002] In a power system, in order to provide a reliable interface for electric wires, terminal blocks are usually installed in the power system, so that the electric wires can be connected more easily and quickly, improving the overall performance and reliability of the power system. Existing terminal blocks usually consist of an insulating housing, an inlet interface, and an operating rod.

[0003] For example: The invention patent with the application number CN201910876684.4 discloses a terminal block, which specifically includes an insulating mounting base and a support member for connecting a wire. An installation groove for accessing the wire is formed in the insulating mounting base, and the support member is arranged in the installation groove. The terminal block further includes a pressing member and a clamping mechanism. The pressing member is used to cooperate with the support member to clamp the wire, and the clamping mechanism is used to lock the pressing member to the insulating mounting base; when the terminal block is connected to the wire, after the wire is inserted into the installation groove, the pressing member is loaded into the installation groove, and the pressing member presses the wire against the support member, and the pressing member and the insulating mounting base are locked through the clamping mechanism. In the present invention, when the wire is connected, the pressing member is locked to the insulating mounting base through the clamping mechanism, so as to realize the pressing of the wire. The operation of the clamping mechanism is convenient, and no tool is required for operation, which is convenient for wire connection and can adapt to the operation in a narrow space.

[0004] However, the inlet interfaces of existing terminal blocks are usually exposed. During use or storage, dust and particles in the surrounding environment will enter the inlet interfaces of the terminal blocks through air flow and accumulate. The accumulated dust will increase the resistance inside the inlet interfaces, resulting in poor contact, unstable current transmission, affecting the normal operation of the power system, and being relatively inconvenient to use. Summary of the Invention

[0005] In view of this, the present invention provides a detachable terminal block, which has a sealing baffle that can not only prevent dust from entering the introduction interface but also assist in fixing the wire. In the initial state, the sealing baffle seals the introduction opening. As the fixed rotating plate is erected, it will drive the sealing baffle to be erected. Then, the wire is inserted into the introduction opening through the friction roller. Subsequently, the operating lever is toggled to reset it. As the operating lever resets, it will drive the first belt pulley to rotate again. During the rotation of the first belt pulley, the second belt pulley will be driven to rotate in the reverse direction through the transmission belt. As the second belt pulley rotates in the reverse direction, the above-mentioned movement will run in the reverse direction, causing the fixed rotating plate to fall again. After the fixed rotating plate falls again, the wire will squeeze the sealing baffle, causing the sealing baffle to drive the guiding slide plate to slide in the guiding chute and squeeze the connecting spring, so that the sealing baffle will neither interfere with the connection of the wire nor fix the wire to a certain extent.

[0006] The present invention provides the purpose and efficacy of a detachable terminal block, which specifically includes: an insulating housing; two disassembly and assembly threaded plates are symmetrically and fixedly connected to the rear of the insulating housing; a set of threaded holes are symmetrically penetrated through the front end faces of the two disassembly and assembly threaded plates; an operating lever is rotatably connected to the upper part of the insulating housing; an introduction opening is opened at the lower part of the front end face of the insulating housing; the position of the introduction opening is aligned with that of the operating lever; two sealing protection boxes are symmetrically and fixedly connected to the outside of the insulating housing; two fixed vertical plates are symmetrically and fixedly connected to the front end face of the insulating housing; the two fixed vertical plates are respectively aligned with the positions of the two sealing protection boxes; a connecting rotating shaft is rotatably connected in each of the two fixed vertical plates; a fixed rotating plate is fixedly connected to the outside of each of the two connecting rotating shafts.

[0007] Further, two first belt pulleys are symmetrically and coaxially fixedly connected to the outside of the rotating shaft of the operating lever; two second belt pulleys are symmetrically rotatably connected to the outside of the insulating housing; the positions of the two second belt pulleys are respectively aligned with those of the two first belt pulleys; the two second belt pulleys and the two first belt pulleys are respectively connected by a transmission belt.

[0008] Further, a control worm is coaxially fixedly connected to the outside of each of the two second belt pulleys; two transmission rotating shafts are symmetrically rotatably connected to the outside of the insulating housing; the two transmission rotating shafts are respectively arranged in the two sealing protection boxes; a control worm gear is fixedly connected to the rear of each of the two transmission rotating shafts; the two control worm gears are respectively meshed with the two control worms.

[0009] Further, a first bevel gear is fixedly connected to the front of each of the two transmission rotating shafts; a second bevel gear is fixedly connected to the outside of each of the two connecting rotating shafts; the two second bevel gears are respectively meshed with the two first bevel gears.

[0010] Further, a guiding sliding groove is formed in the inner side of each of the two fixed rotating plates; a guiding sliding plate is slidably connected in each of the two guiding sliding grooves; a connecting spring is fixedly connected to the top surface of each of the two guiding sliding plates; the ends of the two connecting springs are respectively fixedly connected to the two guiding sliding grooves; a sealing baffle is fixedly connected between the two guiding sliding plates; the sealing baffle is aligned with the introducing opening.

[0011] Further, two fixing frames are symmetrically and fixedly connected to the front part of the insulating housing; a fixing slider is slidably connected to the outside of each of the two fixing frames; a friction rotating roller is rotatably connected between the two fixing sliders; the friction rotating roller is movably connected within the two fixing frames; a connecting plate is fixedly connected to the rear part of each of the two fixing frames; a set of auxiliary springs is fixedly connected to the front part of each of the two connecting plates; the ends of the two sets of auxiliary springs are respectively fixedly connected to the rear end surfaces of the two fixing sliders.

[0012] Further, two auxiliary torsion springs are symmetrically and fixedly connected to the outside of the friction rotating roller; the ends of the two auxiliary torsion springs are respectively fixedly connected within the two fixing sliders.

[0013] Further, two auxiliary extrusion rods are symmetrically and fixedly connected to the outside of the friction rotating roller; a pressure switch is fixedly connected to the outside of each of the two fixing sliders; the two pressure switches are respectively aligned with the two auxiliary extrusion rods; a small warning light is bolted and fixedly connected to the front part of each of the two fixing sliders; the two small warning lights are electrically connected to the two pressure switches respectively.

[0014] Beneficial effects

[0015] During the wiring process of the present invention, in the initial state, the sealing baffle will block the introducing opening to provide dust protection for the introducing opening. During the wiring process, as the operating lever rotates, it will drive the first transmission pulley to rotate. As the first transmission pulley rotates, it will drive the second transmission pulley to rotate through the transmission belt. During the rotation of the second transmission pulley, a series of transmissions will cause the fixed rotating plate to stand up. During the process of the fixed rotating plate standing up, the sealing baffle will stand up to expose the introducing opening. After the wiring is completed, the operating lever is toggled again to make it fall to fix the wire. At this time, through a series of transmissions again, the sealing baffle will fall. At this time, the connected wire will squeeze the sealing baffle, causing the sealing baffle to slide, which will neither interfere with the connection of the wire nor will it fix the wire to a certain extent. The operation is simple and fast, effectively improving the practicability of the terminal, preventing dust from entering the introducing opening, ensuring the connection effect between the wire and the terminal, and making it more convenient to use.

[0016] When wiring the wire, first pull the fixed slider, so that the fixed slider drives the friction roller to move and stretch the auxiliary spring. After inserting the wire into the introduction opening, release the fixed slider, so that the fixed slider resets with the rebound of the auxiliary spring. As the fixed slider resets, the friction roller will clamp the wire to fix the wire, ensuring the stability of the connection between the wire and the terminal.

[0017] When the connected wire is pulled, as the wire moves, the friction roller will rotate. During the rotation of the friction roller, it will drive the auxiliary extrusion rod to rotate. As the auxiliary extrusion rod rotates, it will slowly contact the pressure switch. When the auxiliary extrusion rod rotates to the pressure switch, it will squeeze the pressure switch, causing the pressure switch to activate the small warning light to prompt the staff, which can quickly attract the attention of the surrounding people, remind the staff that the wire at the terminal here has been pulled a long distance, timely discover potential safety hazards, facilitate the staff to perform maintenance in time, improve the safety of the terminal, and can also quickly help the maintenance personnel locate the problem, reduce the troubleshooting time, and improve the maintenance efficiency.

[0039] Specific usage and function of this embodiment: In the present invention, the cooperation of the dismountable threaded plate 101 and the bolt enables the staff to quickly disassemble and assemble the wiring terminal. When using the wiring terminal to connect wires, by rotating the operating lever 102, the first pulley 105 will be driven to rotate during the rotation of the operating lever 102. During the rotation of the first pulley 105, the second pulley 106 will be driven to rotate through the transmission belt. During the rotation of the second pulley 106, the control worm 107 will be driven to rotate. During the rotation of the control worm 107, the control worm gear 109 engaged with it will be driven to rotate. Due to the self-locking characteristic between the control worm 107 and the control worm gear 109, only the control worm 107 can drive the control worm gear 109 to rotate, while the control worm gear 109 cannot drive the control worm 107 to rotate. During the rotation of the control worm gear 109, the transmission shaft 108 will be driven to rotate. During the rotation of the transmission shaft 108, the first bevel gear 110 will be driven to rotate. During the rotation of the first bevel gear 110, the second bevel gear 113 engaged with it will be driven to rotate. During the rotation of the second bevel gear 113, the connecting shaft 112 will be driven to rotate within the fixed vertical plate 111. As the connecting shaft 112 rotates, the fixed rotating plate 114 will be driven to flip. When the fixed rotating plate 114 is erected, in the initial state, the sealing baffle 118 seals the introduction opening 103. As the fixed rotating plate 114 is erected, the sealing baffle 118 will be driven to stand up. Then, the wire is inserted into the introduction opening 103 through the friction roller 121. Subsequently, the operating lever 102 is toggled to reset it. As the operating lever 102 resets, the first pulley 105 will be driven to rotate again. During the rotation of the first pulley 105, the second pulley 106 will be driven to rotate in the reverse direction through the transmission belt. As the second pulley 106 rotates in the reverse direction, the above-mentioned movement will run in the reverse direction, causing the fixed rotating plate 114 to fall again. After the fixed rotating plate 114 falls again, the wire will squeeze the sealing baffle 118, causing the sealing baffle 118 to drive the guiding sliding plate 116 to slide within the guiding chute 115 and compress the connecting spring 117, so that the sealing baffle 118 will neither hinder the connection of the wire nor fix the wire to a certain extent. When connecting the wire, first pull the fixed slider 120 to drive the friction roller 121 to move and stretch the auxiliary spring 127. After inserting the wire into the introduction opening 103, release the fixed slider 120, and the fixed slider 120 will reset with the rebound of the auxiliary spring 127. As the fixed slider 120 resets, the friction roller 121 will clamp the wire to fix the wire. When the connected wire is pulled, as the wire is pulled, the friction roller 121 will be driven to rotate.

[0040] Embodiment Two:

[0041] Based on the first embodiment, please refer to Figures 9 to 10 As shown in the figure, it includes: an auxiliary extrusion rod 122, a pressure switch 123, and a small warning light 124. Two auxiliary extrusion rods 122 are symmetrically and fixedly connected to the outside of the friction rotating roller 121; a pressure switch 123 is fixedly connected to the outside of each of the two fixed sliders 120; the two pressure switches 123 are aligned with the positions of the two auxiliary extrusion rods 122 respectively; a small warning light 124 is bolted and fixedly connected to the front of each of the two fixed sliders 120; the two small warning lights 124 are electrically connected to the two pressure switches 123 respectively.

[0042] The specific usage method and function of this embodiment: In the present invention, during the rotation of the friction rotating roller 121, the auxiliary extrusion rod 122 will be driven to rotate. As the auxiliary extrusion rod 122 rotates, it will gradually come into contact with the pressure switch 123. When the auxiliary extrusion rod 122 rotates to the position of the pressure switch 123, it will squeeze the pressure switch 123, causing the pressure switch 123 to activate the small warning light 124 to give a prompt to the staff, reminding the staff that the wire at the wiring terminal here has been pulled a long distance, and prompting the staff to perform detection in a timely manner.
