Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, and more specifically, to an adaptive and efficient terminal block structure. Background Art

[0002] In the power system, terminal blocks are used to connect various electrical equipment and cables to achieve power transmission and distribution. Adaptive and efficient terminal blocks can improve the reliability and stability of the power system and reduce the probability of failure. A large number of cables need to be connected through terminal blocks. Efficient and reliable terminal blocks are crucial to ensure the normal operation of the power system.

[0003] The connection and fixation of existing terminal blocks are generally bolt-tightening connections. When connecting, the cable is plugged into the live connector on the terminal block, which is less safe. Therefore, it is generally necessary to turn off the power before making the connection. However, turning off the power in order to connect a cable is quite troublesome.

[0004] After searching, the Chinese patent with authorization announcement number CN107834228A discloses a safe and efficient terminal block. The device rotates the rocker arm to disengage from the horizontal groove of the terminal seat, that is, the conductive column realizes the disconnection of the upper connecting seat and the lower connecting seat. Then, it is safer to install the cable on the lower connecting seat. It can be safely connected by using the rocker arm without turning off the main power supply. The terminal block can disconnect the connected connector from the connector connected to the power supply when connecting the cable, thereby improving the safety of the cable connection.

[0005] However, when this structure is actually used, the device is an integrated design as a whole, which makes it impossible for users to freely adjust the distance between adjacent wiring positions or disassemble it according to actual needs, and thus it is difficult to adapt to the connection of wires of different numbers and specifications, resulting in low versatility and flexibility of the terminal block, especially when it is necessary to connect complex circuits with multiple different types of wires.

[0008] An adaptive and efficient terminal block structure includes a fixed frame, a fixed plate fixedly provided on one side of the fixed frame, a slide groove provided at the bottom of the fixed plate, a plurality of L-shaped slide bars slidably connected to the interior of the slide groove, and a disassembly mechanism provided on one side of the L-shaped slide bar;

[0009] The disassembly mechanism includes a connecting frame fixedly arranged on one side of the L-shaped sliding bar, a plurality of limiting holes are provided on the surface of the fixing plate, the interiors of the plurality of limiting holes are clamped with limiting strips, a U-shaped clamping block is fixedly provided on the top of the limiting strip, a stabilizing frame is fixedly provided on one side of the fixing plate, a movable groove is provided inside the stabilizing frame, a fixed door is clamped inside the movable groove, threaded holes are provided on the surfaces of the stabilizing frame and the fixed door, and bolts are threadedly connected to the interiors of the threaded holes.

[0010] By adopting the above technical solution, it is not only convenient for users to install and maintain, but also can be adjusted and expanded at any time according to changes in the circuit, thereby improving the overall adaptability and scalability of the device.

[0013] As a further description of the above technical solution: a base is fixedly provided at the bottom of the fixing frame, and fixing ears are provided on both sides of the base.

[0014] By adopting the above technical solution, the device can be conveniently fixed as a whole, and the installation is quick and easy.

[0015] The technical effects and advantages of this utility model are:

The operation is convenient. At the same time, the bolt is rotated in the opposite direction to drive the bolt to be removed from the inside of the threaded hole, open the fixed door, and then remove the terminal block. This allows users to choose different numbers and types of modules to combine according to actual needs to form a terminal block that meets specific needs;

[0017] 2. By setting up an adjustment mechanism, compared with the existing technology, if the diameter of the wire is large or the insertion angle does not match the initial position, the threaded column can be rotated in the opposite direction to remove the threaded column from the inside of the thread groove, and then the terminal seat can be moved back and forth to drive the T-shaped block to move inside the movable groove. After moving to the appropriate position, the threaded column is rotated forward into the threaded groove at the appropriate position and then fixed. It can better adapt to the size of the wire, and the terminal seat can be moved to make the terminal seat move at an angle, further ensuring the clamping effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The disassembly mechanism includes a connecting frame 5 fixedly arranged on one side of the L-shaped slide bar 4, a plurality of limiting holes 6 are opened on the surface of the fixing plate 2, and the limiting strips 7 are clamped inside the plurality of limiting holes 6, and a U-shaped clamping block 8 is fixedly arranged on the top of the limiting strip 7, and a stabilizing frame 9 is fixedly arranged on one side of the fixing plate 2. A movable groove is opened inside the stabilizing frame 9, and a fixed door 10 is clamped inside the movable groove. The surfaces of the stabilizing frame 9 and the fixed door 10 are provided with threaded holes, and the internal threads of the threaded holes are connected with bolts 11. When it is necessary to adjust the distance between the multiple terminal seats 15, the U-shaped clamping block 8 can be pulled upward to drive the limiting strip 7 at the bottom to be taken out from the inside of the limiting hole 6, and then the position of the terminal seat 15 is moved to drive the connecting frame 5 to move, and the connecting frame 5 drives the L-shaped slide bar 4 to move inside the slide groove 3, thereby improving stability, and then after moving to the appropriate position, the limiting strip 7 is inserted into the limiting hole 6 at the appropriate position, thereby changing the spacing between the terminal seats 15;

[0027] Moreover, when the terminal seat 15 needs to be disassembled, the bolt 11 is rotated in the opposite direction to drive the bolt 11 to be removed from the inside of the threaded hole, and then the fixed door 10 is pulled upward to drive the fixed door 10 to be removed from the movable groove opened inside the stabilization frame 9, and then the terminal seat 15 is pulled outward to drive the connecting frame 5 to move, and the connecting frame 5 drives the L-shaped slide 4 to move inside the slide groove 3, and then slides out directly from one side of the fixed plate 2, and then removes the terminal seat 15, so that the user can choose different numbers and types of modules to combine according to actual needs to form a terminal block that meets specific needs.

[0028] Reference Figures 2-4 As shown, the interior of the connection frame 5 is provided with an adjustment mechanism, which includes a movable groove 12 provided inside the connection frame 5, a T-shaped block 13 is slidably connected to the interior of the movable groove 12, a plurality of threaded grooves are provided on the surface of the T-shaped block 13, and a threaded column 14 is connected to the internal thread of the threaded groove. One end of the threaded column 14 passes through the connection frame 5 and extends to the outside of the connection frame 5. The top of the T-shaped block 13 is rotatably connected to the terminal seat 15, and a conductive sheet 16 is fixedly provided on the top of the terminal seat 15. A fixing groove 17 is provided on the surface of the conductive sheet 16. The internal thread of the fixing groove 17 is connected to a screw 18, and the external rotation of the screw 18 is provided with a metal clip 19. The wire will be accurately inserted into the top of the conductive sheet 16 along the terminal base 15, and then the screw 18 will be rotated to gradually screw in along the thread direction of the fixing groove 17. As the screw 18 continues to screw in, it drives the metal clip 19 to gradually approach and contact the wire. When the screw 18 continues to screw in, it will generate pressure on the wire. This pressure will cause the metal clip 19 to clamp the wire. Since the metal clip 19 and the conductive sheet 16 are in close contact with the wire, an electrical connection is achieved. At the same time, the tightening force of the screw 18 can ensure the stability and reliability of this connection. Even under conditions of vibration, external force, etc., the wire is not easy to fall off from the terminal.

[0029] Reference Figure 1 As shown, a base 20 is fixedly provided at the bottom of the fixed frame 1, and fixing ears 21 are provided on both sides of the base 20. By rotating the external bolts forward into the interior of the fixing ears 21, the base 20 is fixed in a suitable position to enhance stability.

[0030] Working principle of this utility model:

[0031] The present invention is an adaptive and efficient terminal block structure. When the device is in use, the wire is first accurately inserted into the top of the conductive sheet 16 along the terminal base 15, and then the screw 18 is rotated to gradually screw in along the thread direction of the fixing groove 17. As the screw 18 is continuously screwed in, it drives the metal clip 19 to gradually approach and contact the wire. When the screw 18 continues to be screwed in, pressure is generated on the wire. This pressure causes the metal clip 19 to clamp the wire. Since the metal clip 19 and the conductive sheet 16 are in close contact with the wire, an electrical connection is achieved. At the same time, the tightening force of the screw 18 can ensure the stability and reliability of the connection. Even under the conditions of vibration, external force pulling, etc., the wire is not easy to fall off from the terminal. Then, the external bolt is rotated forward to enter the interior of the fixing ear 21, so as to fix the base 20 in a suitable position and enhance stability.

[0032] Moreover, if the diameter of the wire is large or the insertion angle does not match the initial position, the threaded column 14 can be rotated in the reverse direction to remove the threaded column 14 from the inside of the thread groove, and then the terminal seat 15 can be moved back and forth to drive the T-shaped block 13 to move inside the movable groove 12, and then after moving to the appropriate position, the threaded column 14 is rotated forward to enter the thread groove at the appropriate position, and then fixed, which can better adapt to the size of the wire, and the terminal seat 15 can be moved, so that the terminal seat 15 can be moved at an angle to further ensure the clamping effect;

[0033] Moreover, when the distance between the multiple terminal blocks 15 needs to be adjusted, the U-shaped block 8 can be pulled upward to drive the limiting strip 7 at the bottom to be taken out from the inside of the limiting hole 6, and then the position of the terminal block 15 can be moved to drive the connecting frame 5 to move, and the connecting frame 5 drives the L-shaped slide 4 to move inside the slide groove 3, thereby improving stability. After moving to the appropriate position, the limiting strip 7 is inserted into the limiting hole 6 at the appropriate position, thereby changing the spacing between the terminal blocks 15;

[0034] Moreover, when the terminal seat 15 needs to be disassembled, the bolt 11 is rotated in the opposite direction to drive the bolt 11 to be removed from the inside of the threaded hole, and then the fixed door 10 is pulled upward to drive the fixed door 10 to be removed from the movable groove opened inside the stabilization frame 9, and then the terminal seat 15 is pulled outward to drive the connecting frame 5 to move, and the connecting frame 5 drives the L-shaped slide 4 to move inside the slide groove 3, and then slides out directly from one side of the fixed plate 2, and then removes the terminal seat 15, so that the user can choose different numbers and types of modules to combine according to actual needs to form a terminal block that meets specific needs.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
