Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically a terminal block with high integration and protection functions. Background Technology

[0002] Terminal blocks, as a key component in electrical connection systems, are widely used in power, automation control, industrial equipment and other fields. Their function is to realize the reliable connection between cables and electrical components. Traditional terminal blocks usually consist of a terminal body and a simple installation structure, which face problems such as insufficient protection performance and poor cable fixing reliability in actual use. Currently, most terminal blocks lack effective sealing and protection structures. In industrial environments (such as dusty workshops and humid places), dust, moisture, and other impurities can easily enter the interior through the connection holes or exposed gaps of the terminal block. Dust accumulation can lead to increased terminal contact resistance and poor contact; moisture intrusion can cause oxidation and corrosion of the terminal metal components, and even cause short circuit faults, seriously affecting the stability and safety of the electrical system. During equipment inspection or maintenance, since terminal blocks usually connect multiple cables, the dragging and pulling of cables by workers can easily cause the connection between the cables and the terminal blocks to loosen. Traditional terminal blocks only fix the cables with simple methods such as bolts, lacking additional mechanical clamping structures, and cannot effectively resist external interference. Loose cables can not only cause circuit interruptions, but may also cause unexpected power outages and equipment failures during maintenance, increasing maintenance costs and safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide a terminal block with high integration and protection functions to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a terminal block with high integration and protection functions, comprising a terminal block, a protective shell at the top of the terminal block, fixing members on both sides of the protective shell, a cover plate rotatably connected to the top of the protective shell, a magnet fixed to the bottom of the cover plate, a groove plate fixed to the side wall of the protective shell, a cavity formed inside the groove plate, a turntable rotatably connected inside the cavity, a slider fixed to the bottom of the turntable, spiral strips symmetrically fixed to the outer walls of both sides of the turntable, a clamping plate slidably connected to the outer wall of the spiral strips, and the side of the clamping plate away from the spiral strips slidably connected to the groove plate, a connecting rod fixed to the top of the turntable, a driving disk fixed to the outer side of the connecting rod, the driving disk being disposed on the outer side of the groove plate, and a snap-fit ​​member at the top of the driving disk.

[0005] Preferably, both the protective shell and the cover are made of transparent acrylic material.

[0006] Preferably, a square iron block is provided on the protective shell at the position of the magnet at the bottom of the cover plate, so that the magnet can be attracted to its surface to fix the cover plate.

[0007] Preferably, the fixing component includes a slot block, which is fixed to the top of both sides of the terminal block. A locking block is engaged inside the slot block, and a support plate is fixed to the top of the locking block. The side wall of the support plate is connected to the protective shell.

[0008] Preferably, the snap-fit ​​component includes a limiting plate, which is disposed at the top of the drive disk, and the side wall of the limiting plate is connected to the protective shell. A spring is fixed at the top of the drive disk, and a limiting block is fixed at the top of the spring, and the limiting block is inserted into the interior of the limiting plate.

[0009] Preferably, the limiting plate has equidistant limiting grooves inside that match the limiting block.

[0010] Preferably, the position where the clamping plate connects to the spiral strip is provided with a spiral groove that matches the spiral strip, and when the turntable drives the spiral strip to rotate, it can drive the clamping plate to move inward or outward through the cooperation with the spiral groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Sealed protection design: The protective shell is made of transparent acrylic material, with a magnetic and square iron block adsorption structure that can completely cover the top opening of the terminal block, effectively preventing dust, moisture and other substances from entering the interior, avoiding short circuits or poor contact caused by environmental factors, extending the service life of the equipment, and providing visual monitoring. The transparent material makes it easy to observe the cable connection status and operation of the terminal block in real time without the need for frequent disassembly of the cover, thus improving maintenance efficiency.

[0012] Screw drive clamping mechanism: The turntable engages with the spiral groove of the clamping plate via a spiral strip. Rotating the drive disc moves the clamping plate inward, clamping the cable with anti-slip rubber pads. This provides high friction and even force distribution, preventing the cable from loosening due to dragging or vibration, and ensuring the stability of the electrical connection. Limit and locking design: The slider at the bottom of the turntable engages with the groove plate's limit structure to prevent axial movement, allowing only circumferential rotation and ensuring the clamping plate's movement accuracy. The drive disc is locked by a spring and a snap-fit ​​mechanism with the limit plate to prevent accidental rotation of the turntable, ensuring a durable and reliable cable fixation.

[0013] Modular fixing components: The fixing components adopt a precise snap-fit ​​design of slot blocks and clip blocks. The protective shell and terminal block are connected by a support plate. No additional tools are required during installation. It can be quickly snapped and fixed, improving assembly efficiency. At the same time, it is easy to disassemble and maintain. Cable management is integrated. The slot plate and turntable assembly are integrated into the side wall of the protective shell. After the cable passes through the center of the slot plate, it is directly clamped by the clamp plate. No additional binding tools are required, simplifying the wiring process, reducing space occupation, and realizing a highly integrated layout of the terminal block.

[0014] Quick-opening cover: The cover is fixed by magnetic attraction and can be easily opened by pulling the pull block upwards. No screws are required for disassembly, reducing the difficulty of operation and shortening maintenance time. The anti-misoperation design features a spring limit block structure on the drive plate that can automatically lock after clamping the cable to prevent external force from accidentally causing the clamp to loosen. At the same time, the multi-slot design of the limit plate can adapt to the fixing needs of cables of different diameters, providing high flexibility. Attached Figure Description

A spiral groove matching the spiral strip is provided at the connection point between the spiral strip 12 and the clamping plate 13. This design allows the turntable 10 to rotate the spiral strip 12, thereby moving the clamping plate 13 inwards or outwards through the engagement with the spiral groove. The clamping plate 13 is slidably connected to the outer wall of the spiral strip 12. An anti-slip rubber pad is provided on the inner side of the clamping plate 13. When the clamping plate 13 moves inwards to clamp the cable, the anti-slip rubber pad increases friction and prevents the cable from slipping. To ensure the cable is securely fixed, the side of the clamp 13 away from the spiral strip 12 is slidably connected to the slot plate 9. A connecting rod 14 is fixed to the top of the turntable 10. The connecting rod can transmit the force of the drive plate 15 to the through plate 10. The drive plate 15 is fixed to the outside of the connecting rod 14 and is located on the outside of the slot plate 9. A snap-fit ​​is provided at the top of the drive plate 15. Both the protective shell 2 and the cover plate 6 are made of transparent acrylic material. A square iron block is provided on the protective shell 2 at the position of the magnet at the bottom of the cover plate 6, so that the magnet 8 can be attracted to its surface to fix the cover plate 6.

[0019] The fastener includes a slot 3, which is fixed to the top of both sides of the terminal block 1. The inside of the slot 3 is designed as a slot of a specific shape to match the slot 4. The slot has high dimensional accuracy, which can achieve precise engagement of the slot 4. The slot 4 is engaged inside the slot 3.

[0021] Working Principle: When using a terminal block with high integration and protection functions, if it is necessary to connect the cable in the terminal block 1, the user first fastens the protective shell 2 on top of the terminal block 1, then inserts the locking block 4 into the slot 3. After the locking block 3 is inserted into the slot 3, it can be fixed to the protective shell 2 through the connection of the support plate 5. Then, the user pulls the block 7 upward, which causes the cover plate 6 to rotate. The magnet 8 at the bottom of the cover plate 6 separates from the square iron block. Then, the user passes the cable through the center of the slot plate 9, extends it into the protective shell 2, and inserts it into the connection port of the terminal block 1. After insertion, the operator uses a tool to rotate the bolt from the top of the protective shell 2 to fix the cable to the terminal block 1. After fixing, the user moves the limiting block 18 towards the... Pulling down pulls the limiting block 18 out of the limiting plate 16. When the limiting block 18 moves downward, it compresses the spring 17. Then, the user rotates the drive disk 15. When the drive disk 15 rotates, it drives the turntable 10 to rotate inside the slot plate 9 through the connecting rod 14. When the turntable 10 rotates, it is limited by the slider 11. Then, when the turntable 10 rotates, it drives the clamping plate 13 to move inward through the spiral strips 12 on both sides. When the clamping plate 13 moves inward, it supports the outer wall of the cable to prevent the cable from being dragged and separated from the terminal block 1 during maintenance. After the cable is supported, the user releases the limiting block 18. The reaction force of the spring 17 inserts the limiting block 18 into the limiting plate 16 to lock the drive disk 15.
