Description

Technical Field

[0001] This utility model relates to a shielded cross connector for switch cabinets. Background Technology

[0002] Shielded cross-joints for switchgear are key components used for busbar cable connections in switchgear such as ring main units and gas-insulated switchgear, achieving fully insulated and sealed electrical connections. Existing switchgear cross-joints, when connected to cable assemblies at both ends, are frequently subjected to tensile forces, which can easily damage the cable core. Damaged cable cores lead to loose crimping, insulation slippage, and core wire damage, creating "virtual connections" with poor contact, affecting the safety and stability of the connection. Improvements and optimizations are therefore proposed to address these issues. Utility Model Content

The part 21 has a longitudinally arranged through hole for the connector mating part that communicates with the middle of the cross connector cable hole 22. The cable locking member 8 has a locking member inner hole 27 that is sleeved on the cross connector cable passage part 20. The inner wall of the locking member inner hole 27 is provided with cable locking blocks 28 at intervals around the arc. The two ends of the cross connector cable passage part 20 are provided with cable passage part outer limiting grooves 29 for limiting the installation of the cable locking member 8. The bottom of the cable passage part outer limiting groove 29 is provided with cable passage part clamping openings 30 at intervals around the arc, corresponding to the cable locking blocks 28.
