Clamped/Spring Connections TRIZ Cases

A screwless terminal block uses a sliding mechanism to penetrate wire insulation and clamp conductors securely.

A direct plug-in compression spring terminal uses a spaced second contact zone to guide and center conductor strands during insertion.

A terminal clamp uses a narrowing guide channel to center conductors during insertion.

Angled frame surfaces and a U-bolt clamp conductors and pedestals, accommodating varied grid configurations without complex structures.

A pivotally mounted cover part guides conductors and actuates a clamping spring for tool-free insertion.

Longitudinal contact ribs on the busbar reduce insertion force and prevent conductor twisting while maintaining high clamping pressure.

Segmented bonding connectors replace drilling and welding with manual fastening, reducing installation time while maintaining reliable electrical grounding.

Mobile contact parts follow twisted feeder cable inclinations to maintain optimal alignment and reduce installation complexity.

Side-mounted ground rod connectors with precision-drilled holes and set screws accommodate thermal expansion while preventing loosening after installation.

A screwless terminal uses a leaf spring and moveable operator to clamp electrical leads without screws.

An insulating actuating element pivots a clamping spring to prevent accidental contact while maintaining electrical conductivity.

A press and spring-back terminal block uses a rocker to actuate an elastic sheet, eliminating two-handed tool pressure during lead wire insertion.

A grounding clamp employs a segmented locking and balance mechanism to prevent support arm misalignment during tightening operations.
