Relieving Strain On Wire Connection TRIZ Cases

Angular alignment members and elastic cable grips enable low-force mating, protect contacts, and prevent cable movement from damaging joints.

Grooves and a rotatable cover align coated wires and exposed conductors for reliable pressure contact on narrow-pitch substrate terminals.

A hinged cover with a wire pressing portion secures the wire while cutting separate cover parts, assembly complexity, and cost.

A housing stopper limits sheath advance near draw-out openings, keeping differential wires spaced correctly and preserving transmission characteristics.

A routing groove and guide structure keep exposed differential wires aligned during terminal insertion to preserve transmission characteristics.

An insert and overmolded sleeve replace separate grommets to seal the cable end, provide strain relief, and shorten plug connector assembly.

A tapered support sleeve improves axial positioning, crimp stability, and impedance matching for vibration-proof high-frequency cable connections.

A ramped rotary clamp displaces a lamella to grip cables quickly in tight spaces while enabling precise torque-based strain relief.

Coupling teeth lock the pinch sleeve against rotation, maintaining cable clamping force over time without damaging the sheath.

A single retainer with supporting members presses resilient pieces onto each wire, cutting parts count while keeping multi-wire holding stable.

Braided copper-clad aluminum wires cut connection count between transformers and modules while improving flexibility, retention, and conductivity.

A slotted retention wall plate secures USB charging connectors in AC/DC outlets to prevent cable removal, wear, and theft.

A pivoting lid drives a spring clamp to secure exposed cable ends, cutting junction box wiring time without sacrificing connection reliability.

A slotted pin contact plugs directly into PCB through-holes to carry high current while avoiding complex soldered connector assembly.

A U-shaped terminal and elastic lance geometry resist pull-force disengagement and damage while keeping wire-to-board connectors compact.

Pivoting cable covers form a support sleeve that fits multiple cable angles and diameters while reducing housing variants and storage needs.

A polymer cable bracket and arced guide organize antenna coaxial cables, maintain bend radius, and reduce PIM from metal contact.

A one-way locking tightening sleeve secures cable connectors against tool-free loosening while still accommodating varying cable diameters.
