Incorrect Coupling Prevention TRIZ Cases
- Modular Connector Housing for Hybrid Optical and Electrical Signals
A modular connector housing accepts interchangeable inserts to join optical fiber and electrical conductors within a single unit.
- Connector Lock Arm with Entrance Space for Stress Dispersion
A connector lock arm features an inclined leg and entrance space that receives the mating housing tip to disperse stress during unlocking.
- Electrical Connector Cover Prevents Premature Lock Actuation
A sliding cover masks the lock mechanism during initial assembly to prevent accidental engagement.
- Connector Position Assurance Device Independent Fulcrum Latch
Independent CPA devices prevent inadvertent separation by providing clear tactile feedback without increasing latch complexity.
- Aircraft Cabin Fitting Fastening System with Integrated Electrical Contacts
Integrates bush and plug electrical contacts into mechanical bearings for single-step aircraft cabin fitting installation.
- Female Connector Groove Design for Pin Load Reduction
Gradually shallower grooves on the female connector guide male projections to absorb displacement, preventing pin breakage under load.
- Interlocked Shell and Housing Electrical Connector
Interlocked shell and housing portions create an interference fit that resolves automated production inefficiencies in electrical connectors.
- Sensor Unit Torque Isolation via Molded Part
A sensor unit uses a rotationally fixed molded part to absorb torque and protect internal electronics from mechanical stress.
- CPA Element Latch Deflection for Electrical Connector
A connector position assurance element deflects a mating latch via an extending arm to secure electrical connections.
- Electrical Connector CPA Member Flexible Locking Arm
A connector CPA member uses a flexible locking arm with distinct ramp thresholds to prevent accidental blocking during mate assist lever actuation.
- Connector with Branched Terminals for High Current Management
Branched terminal pieces split electric current in parallel paths, reducing Joule heating while maintaining compact vehicle space.
- Polarization Tab Prevents Connector Misalignment
An EMI shielding cage with a rearward polarization tab prevents incorrect connector mating orientations that cause misalignment and electrical failure.
- Connector Guide Protrusion for Terminal Collision Prevention
A connector housing features a guide protrusion at communication hole edges to direct terminal insertion paths.
- Shielding Shell Mating Protrusion Prevents Reverse Connector Insertion
A receptacle connector shielding shell features a mating protrusion that blocks incorrect plug insertion paths.
- Connector Fitting Detection Member Unintentional Release Prevention
A connector fitting detection member uses a deflection regulator to maintain engagement.
- PCB Connector Locking Mechanism Space Optimization
A printed circuit board connector integrates locking and holding devices between contact rows to maximize installation space.
- Resilient CPA Locking Element for Connector Stability
Resiliently deflected locking elements in a CPA device reduce stress on components while maintaining reliable connection stability.
- Connector Guide Grooves for Assembly Alignment
A connector housing uses guide grooves to displace a detection member from a pre-assembling position.
- Card Edge Connector Covering Block for Rigidity and Grounding
Covering blocks with deflectable latches and abutment ribs secure grounding contacts, restoring rigidity lost when housing portions are removed for shielding.
- Plug Element Contact Lock Test Path Verification
A plug element contact lock member features a test recess forming a defined path for a test member to verify engagement.
- Divided Connector Positioning Frame Eliminates Backlash
A divided connector uses a front part positioning frame to secure the terminal main body within the outer housing.
- Connector Position Assurance Locking Mechanism
A connector position assurance locking mechanism engages a female assembly in a pre-lock position before transport.
