Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically to an anti-loosening terminal block. Background Technology

[0002] In the field of electrical connections, terminal blocks are a commonly used connection component used to achieve electrical connections between wires.

[0003] Traditional terminal blocks are typically secured by simple plugging or screw tightening when connecting wires. However, in actual use, factors such as vibrations from equipment operation, thermal expansion and contraction due to ambient temperature changes, and human contact can easily cause the wires to loosen. Loosening of the wires not only interrupts the electrical connection and affects the normal operation of the equipment, but can also lead to electrical faults and even safety accidents such as short circuits and fires, posing a serious threat to people's lives and property. Therefore, developing a terminal block that can effectively prevent wire loosening is of significant practical importance. Utility Model Content

[0042] Fixed unit 2 includes:

[0043] Snap-in component 21, the snap-in component 21 includes:

[0044] Movable plate 211 is slidably connected to terminal block 1;

[0045] The locking block 212 is a right-angled trapezoid and is movably engaged with the connector.

[0046] Pressure block 213, which is arc-shaped, abuts against the end of the connector.

[0047] The bottom end of the slide rod 22 is fixedly connected to the movable plate 211, and the slide rod 22 is slidably connected to the terminal block 1.

[0048] Furthermore, the movable plate 211 is slidably connected within the cavity 13.

[0049] Furthermore, the snap-fit ​​assembly 21 also includes a slider 214, which is slidably connected within the groove 14.

[0050] Furthermore, the fixing unit 2 also includes:

[0051] Spring 23 is sleeved on the outside of slide bar 22, and the bottom end of spring 23 is fixedly connected to movable plate 211, and the other end of spring 23 is fixedly connected to terminal block 1.

[0052] The handle 24 is fixedly connected to the top of the slide bar 22.

[0053] Working principle:

[0054] When connecting the connector to the anti-loosening terminal block, first insert the connector into the insertion hole 11 on the front of the terminal block 1. During insertion, the connector will press against the pressure block 213 in the locking assembly 21. The pressure block 213, under pressure, pushes the moving plate 211 upwards. Since the moving plate 211 is fixedly connected to the slide rod 22, and the slide rod 22 is slidably connected to the terminal block 1, the moving plate 211 will move the slide rod 22 upwards together. Simultaneously, the spring 23, fixedly connected to the moving plate 211, will be compressed, generating a downward elastic force. When the connector is fully inserted into the insertion hole 11, under the elastic force of the spring 23, the moving plate 211 will move downwards, causing the locking assembly 21 to move downwards, so that the right-angled trapezoidal locking block 212 engages with the connector, and the arc-shaped pressure block 213 abuts tightly against the end of the connector, thereby firmly fixing the connector in the terminal block 1 and preventing it from loosening.

[0055] When it is necessary to disassemble the connector, simply pull the handle 24 upwards. The handle 24 moves the slide bar 22 upwards, which in turn moves the moving plate 211 and the locking assembly 21 upwards, disengaging the locking block 212 from the connector. At this point, the connector can be easily pulled out of the insertion hole 11. After releasing the handle 24, the slide bar 22 and the locking assembly 21 will automatically return to their initial positions under the elastic force of the spring 23, ready for the next wiring operation.
