Description

Technical Field

[0002] Low-voltage power distribution equipment currently mainly includes a enclosure, and main switches, circuit breakers, and terminal blocks housed within the enclosure. Existing terminal blocks typically consist of an insulating outer casing and a main connection plate. The main connection plate is installed inside the insulating outer casing and has a first terminal for electrical connection to the circuit breaker and a second terminal for electrical connection to the main switch. This main connection plate is pre-fabricated according to the model of the circuit breaker being connected, and the distance between adjacent first terminals is not adjustable. This means that the connecting feet on both sides of existing terminal blocks used in low-voltage power distribution equipment are generally fixed, making it inconvenient to connect different specifications of circuit breakers on a single terminal block, resulting in inconvenience in use.

[0003] To address the above issues, utility model patent CN217956310U discloses a multifunctional ribbed terminal block for low-voltage power distribution equipment. It includes a main connecting plate, with a set of second terminals on each side of the main connecting plate. These second terminals are located outside an insulating sleeve and are connected to ball-shaped terminals, which can be connected by a clamping structure. This ribbed terminal block features a set of second terminals extending from the insulating sleeve on each side of the main connecting plate. Each second terminal is connected to a ball-shaped terminal, and each set of ball-shaped terminals can be connected to a ball-shaped clamping foot encased in an insulating shell. A fixed third terminal is mounted on each ball-shaped clamp.

[0004] Although the above-mentioned terminal block frame can be adapted to different specifications of circuit breakers by clamping the ball terminals with ball clamps and then rotating the ball clamps, making it convenient to use, the adjustment range of the ball clamps is limited and the flexibility is low. At the same time, the manufacturing process of the ball clamps is complex and not easy to mass-produce. Utility Model Content
