AI Technical Summary
Existing busbar connectors are prone to loosening of nuts and bolts during prolonged use, leading to loose insulation, increased copper resistance, and severe overheating.
A busbar trunking connector is designed, which adopts a protective plate and an insulating plate structure. It is fixed by setting a first through hole and a second through hole on the connector and the side plate, using four sets of bolts, and setting springs on the bolts to prevent the bolts from being located in the center of the connector, thus maintaining the integrity of the copper sheet structure and improving stability through multi-point fixing.
This effectively avoids increased copper sheet resistance and heat generation caused by loose bolts, increases connector stability and redundancy, and prevents detachment due to single-point loosening.
