Description

TECHNICAL FIELD

[0001] The utility model relates to a transformer low pressure Buddha's hand wire clamp quick power taking connection device. BACKGROUND

[0002] With the rapid development of economy and society, the reliability demand of people for power supply is also improving. Low-voltage uninterrupted operation is one of the important means to reduce customer power outage awareness and improve power supply reliability. Transformer low-voltage Buddha's hand is a common conductive connection device, which is usually fixedly installed on the low-voltage side terminal of the transformer for connecting the low-voltage cable. In the past, when taking power from the low-voltage side of the transformer, there are two methods, one is to take power from the low-voltage cable by piercing the clamp, and the other is to loosen the connection between the transformer low-voltage Buddha's hand and the low-voltage cable, and then connect the copper terminal on the lead wire with the transformer low-voltage Buddha's hand for power taking. However, the previous operation method has the following shortcomings:

[0003] 1. The piercing clamp can pierce the insulation layer of the low-voltage cable, affecting the service life of the cable. The piercing clamp has limited capacity and is generally suitable for small power taking requirements. If the piercing clamp is not selected properly, it may cause loose connection, excessive resistance and other problems, which may cause safety accidents.

[0026] In this embodiment, the top surface of the clamping top block 14 is a flat structure, which is conducive to pressing the protruding plane of the Buddha's hand wire clamp 4.

[0027] In this embodiment, the lower end of the clamp body 12 is provided with a connecting portion 17 extending horizontally toward the left side, and the connecting portion 17 is located directly below the clamping portion 121. The connecting portion 17 is provided with a first screw hole 171 that passes through vertically; the driving mechanism includes a locking screw 16 that passes through the first screw hole 171 vertically, and the locking screw is screwed to the first screw. The upper end of the locking screw 16 is movably connected to the clamping top block 14. When the locking screw 16 rotates, it drives the clamping top block 14 to move up and down. Specifically: the outer peripheral side surface of the upper end of the locking screw 16 is provided with a An annular groove 161 is provided; a circular hole 141 is provided on the bottom surface of the clamping top block 14, the diameter of the circular hole 141 is larger than the diameter of the upper end of the locking screw 16, the upper end of the locking screw 16 extends into the circular hole 141 and can rotate in the circular hole 141, and the front side of the clamping top block 14 is provided with a pair of pins 15 distributed on the left and right, the pins 15 are arranged longitudinally and extend into the inside of the circular hole 141, the pins 15 extend into the annular groove 161 at the upper end of the locking screw 16, and the locking screw is limited by the pin to prevent the upper end of the locking screw 16 from separating from the circular hole.
