Description

Technical Field

[0001] This utility model relates to the field of electrical wiring technology, specifically a high-efficiency operation direct-insertion spring terminal block. Background Technology

[0002] Straight-insertion spring terminals are commonly used components in electrical connections and are widely used in control cabinets, distribution boxes, and other equipment for quick connection of wires.

[0003] In existing technologies, terminals are mostly fastened with screws or simple springs, requiring tools and time for operators. Tightening force is difficult to control, easily leading to wire damage or poor contact. Furthermore, spring-loaded structures are prone to fatigue after long-term use, resulting in insufficient pressure, loosening, and overheating risks. In addition, existing terminals lack effective anti-loosening mechanisms, making wires prone to detachment in vibrating or temperature-changing environments, causing circuit failures. Some improved terminals enhance fastening by adding spring plates or lever structures, but these are complex, costly to manufacture, and inconvenient to maintain. Moreover, traditional equipment lacks sufficient installation and positioning accuracy, resulting in unstable terminal mounting on the guide rail, affecting overall assembly quality and performance. Therefore, we propose a high-efficiency, direct-insertion spring terminal block to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of complex operation, easy loosening of connections, and insufficient installation positioning of existing terminal blocks.

[0005] The specific solution of this utility model is as follows: Design a high-efficiency, direct-insertion spring terminal block, comprising an insulating housing. Two symmetrically arranged insertion holes are formed on the upper surface of the insulating housing. A common conductive plate is positioned below the two insertion holes. The sidewall of the conductive plate is fixedly connected to the inner wall of an adjacent insulating housing. Two symmetrically arranged first positioning plates are fixedly connected to the inner wall of the insulating housing. The lower surfaces of both first positioning plates are fixedly connected to the inner wall of the conductive plate. Two symmetrically arranged anti-loosening button holes are formed on the sidewall of the insulating housing. Sliding sleeves are fixedly connected to the inner walls of both anti-loosening button holes. The other ends of both sliding sleeves are fixedly connected to the sidewalls of adjacent first positioning plates. A [missing information - likely a component or element] is fixedly connected to the upper surface of the two first positioning plates. Two symmetrically arranged second positioning plates are provided. A sliding groove plate is fixedly connected to the top of each of the two second positioning plates. Two symmetrically arranged anti-loosening pressure plates are slidably connected to the inner walls of the two sliding groove plates. A pivot pin is rotatably connected to the inner wall of each of the two anti-loosening pressure plates and the inner wall of each of the two second positioning plates. The same pivot plate is rotatably connected to the surface of each of the two adjacent pivot pins. Two symmetrically arranged fastening modules are fixedly connected to the top of each of the two pivot pins. Two symmetrically arranged spring plates are fixedly connected to the inner walls of each of the two fastening modules. Each of the two spring plates is located below an adjacent insertion hole. Two symmetrically arranged limiting modules are provided inside each of the two spring plates. The surfaces of each of the two limiting modules are slidably connected to the inner walls of the adjacent spring plates.

[0006] In specific implementation, the inner walls of the two sliding sleeves are slidably connected with two symmetrically arranged anti-loosening buttons. The other ends of the two anti-loosening buttons penetrate the side wall of the adjacent first positioning plate and extend to the surface of the adjacent rotating plate. The other ends of the two anti-loosening buttons are located on the rotation trajectory of the adjacent rotating plate.

[0007] In specific implementation, the surfaces of the two anti-loosening buttons are provided with a first annular groove, the inner walls of the two sliding sleeves are provided with a second annular groove, the surfaces of the two first annular grooves are rolledly connected with the same ball bearing to the surfaces of the adjacent second annular grooves, the inner walls of the two sliding sleeves are fitted with springs, one end of the two springs is fixedly connected to the side wall of the adjacent first positioning plate, and the other end of the two springs is fixedly connected to one end of the adjacent anti-loosening button.

[0008] In specific implementation, two symmetrically arranged insulating rubber plugs are provided on one side of the two adjacent insertion holes. The sidewalls of the two insulating rubber plugs are slidably connected to the inner wall of the insulating shell, and the lower surfaces of the two insulating rubber plugs are slidably connected to the surface of the adjacent spring sheet.

[0009] In a specific implementation, two symmetrically arranged retaining blocks are provided between the two fastening modules. The lower surfaces of the two retaining blocks are fixedly connected to the inner wall of the conductive sheet. Two parallel reinforcing ribs are provided above the two retaining blocks. The side walls of the two reinforcing ribs are fixedly connected to the inner wall of the adjacent insulating shell.

[0010] In specific implementation, an identification plate is movably connected to the upper surface of the insulating shell, the identification plate is located between two insulating rubber plugs, and a guide rail mounting base is fixedly connected to the lower surface of the insulating shell. A movable buckle is provided on the left side of the guide rail mounting base, and the movable buckle is connected to the guide rail mounting base.

[0011] The beneficial effects of this utility model are as follows: This utility model, through the cooperative structure of anti-loosening pressure plate, rotating pin, rotating plate, spring plate and limiting module, allows the spring plate to elastically press the wire after it is inserted into the insertion hole. The anti-loosening pressure plate, through the linkage of the rotating pin and rotating plate, can assist in limiting the pressing state of the spring plate, ensuring the stability of the electrical connection and greatly improving the reliability of the wiring. This utility model, through the cooperative structure of anti-loosening button, sliding sleeve, spring and ball, allows the rotating plate to be pushed to rotate when the wire needs maintenance or replacement. This, in turn, causes the anti-loosening pressure plate to release the spring plate's restriction, enabling quick operation. At the same time, the design of the ball and annular groove reduces the friction when the anti-loosening button slides, and the spring enables the anti-loosening button to automatically reset, significantly improving the efficiency of operation. This utility model, by setting up an identification plate, a guide rail mounting base, and a movable buckle, makes it easy to distinguish different wiring terminals by setting the identification plate, while the cooperation of the guide rail mounting base and the movable buckle makes the installation of terminals on the guide rail more convenient and stable, thus improving the convenience of installation and the practicality of the overall structure.

[0015] Two symmetrically arranged anti-loosening buttons 15 are slidably connected to the inner walls of the two sliding sleeves 6. The other ends of the two anti-loosening buttons 15 penetrate through the side wall of the adjacent first positioning plate 4 and extend to the surface of the adjacent rotating plate 11. The other ends of the two anti-loosening buttons 15 are located on the rotation trajectory of the adjacent rotating plate 11. Through the cooperation of the anti-loosening buttons 15 and the rotating plate 11, the wires can be easily disassembled, improving the efficiency of operation.

[0016] Both anti-loosening buttons 15 have a first annular groove 16 on their surfaces, and both sliding sleeves 6 have a second annular groove 17 on their inner walls. The surfaces of both first annular grooves 16 and the surfaces of adjacent second annular grooves 17 are connected by the same ball bearing 18.

The anti-loosening button 15 drives the rotating plate 11 to rotate through the linkage of the rotating pin 10 and the sliding plate 8, so that the anti-loosening pressure plate 9 limits the pressing state of the spring plate 13. When it is necessary to disconnect the wire or perform maintenance, the anti-loosening button 15 is pressed. The anti-loosening button 15 pushes the rotating plate 11 to rotate. The rotating plate 11 drives the rotating pin 10 to release the anti-loosening pressure plate 9 from the limit of the spring plate 13. At this time, the wire can be easily pulled out. After releasing the anti-loosening button 15, the spring 19 pushes the anti-loosening button 15 to reset, completing one operation process.
