Incorrect Coupling Prevention TRIZ Cases
- Connector Plug Bosses Prevent Contact Damage
Asymmetric bosses on the plug align with receptacle slots to prevent midspan insertion and contact damage.
- Connector Assembly Mating Detection Mechanism
A connector assembly uses a mating detecting member to signal connection status through distinct positional states.
- Connector Guide Portions With Projections For Circuit Board Positioning
A connector holding member uses deformable guide projections to securely hold circuit boards within manufacturing tolerances.
- Connector Tube With Partially Closing Wall For Air Hole Protection
A connector tube features a partially closing wall at its leading end to protect the internal air hole from external matter intrusion.
- PCB Contacting Device Using Guided Insertion and Centering
Guided insertion of a printed circuit board into a holder prevents damage from high insertion forces while ensuring reliable electrical connections.
- Connector Detector Resilient Piece Tactile Feedback
A connector detector uses a resilient piece to provide tactile feedback during movement.
- Contact Unit With Rolled Fulcrum Surfaces For Stable Resistance
A contact unit employs a rolled fulcrum surface to stabilize resistance values, eliminating unstable paths caused by complex swaging or welding operations.
- Electrical Connector Foolproof Structure for Miniaturization
Relocating fool-proof portions to the mating cavity surface prevents misinsertion while minimizing space occupancy and maintaining structural strength.
