Clamped/Spring Connections TRIZ Cases

A spring tongue built into the support element adds a busbar clamping point, improving terminal stability and function without extra parts.

A lever-braced actuating element holds the clamp open, enabling one-handed, tool-free insertion of rigid and flexible conductors.

Segmented cover parts simplify conductor terminal assembly, cut insulating material use, and keep spring-loaded clamping reliable.

An angled pushbutton axis and thicker actuating head reduce insulating housing deformation while maintaining reliable conductor clamping.

An integrated separating section in the clamping spring splits shared conductor space into distinct chambers, preventing interference in compact terminals.

An integral busbar retainer snap-fits the clamping spring, removing extra support parts while improving terminal stability and assembly.

An angled actuation path and contoured pressure surface keep spring contact stable, lowering initial release force in conductor terminals.

A rotation-limited handle keeps the wire gap open for insertion and release, avoiding continuous force during connector operation.

Angled actuation regions and a moving pivot path let compact clamping connections release conductors more easily in cramped installations.

A detent-locked spring leg holds the terminal open, then an inserted wire triggers automatic clamping for easy, reliable cable connection.

A linearly guided actuating element improves spring clamp terminal force transfer while limiting overpressure for compact, ergonomic conductor clamping.

A two-axis lever and rotation element opens and clamps conductors without tools, reducing friction losses in compact terminals.

A perpendicular trigger and busbar latch let this spring terminal release its clamping spring with low force while staying compact and secure.

Two spaced fastening elements let a grounding bolt lock from one side, pierce coating, and create electrical contact only when needed.

A separate support plate stiffens the busbar against spring forces, enabling compact conductor terminals with reliable clamping and heat dissipation.

Mechanical clamping with friction-flow-drilled threads replaces welding on coaxial HV cable shields for uniform contact and lower stress.

Directly locking the metal leaf spring to the conductive support prevents detachment from housing deformation and simplifies terminal assembly.

An integrated resilient clamp and pivoting actuator secure a feed-through terminal in a wall opening without extra installation space or loose parts.

A pivoting retaining element lets the inserted conductor release a preloaded leaf spring, simplifying flexible wire clamping and cutting assembly time.

An elastic movable connector maintains housing-to-substrate contact during screw fastening, reducing plastic deformation and improving reassembly.

A busbar slot guides and supports the actuating lever, cutting housing load while keeping the conductor terminal compact and secure.

A flexible terminal lets one wiring device reference either ground or neutral, simplifying retrofit and non-retrofit installation.

A separate crimp-lug connection lets a smaller monitoring wire be added or removed without loosening the main terminal or breaking UL compliance.

A manually operable opening member releases the clamping spring for tool-free terminal removal while keeping busbar contact secure under vibration.
