Couplings Bases/Cases TRIZ Cases

A ribbed waterproof covering member replaces interference-prone O-rings to seal the connector and PCB while improving assembly reliability.

A cam groove and moving pin keep the moving plate stable during temporary coupling, protecting terminals and simplifying connector structure.

A carrier-piece press-fastening structure secures the rubber plug without breakage, preserving sealing force while reducing terminal size and cost.

A pot-shaped cover with an integrated annular seal and potting socket keeps plug connections sealed against water, dust, and corrosion.

Rear hooks clamp cable assemblies while a rubber ring maintains sealing force, helping the connector housing stay watertight.

A ring-like flat spring links the cable shield to the casing, simplifying small connector shield assembly while improving contact reliability.

A spring-loaded annular cover buffers fast switchgear insertion, protecting contact pins from shear, wear, and contamination.

An annular sealing edge and integrated seal enable quick ultrasonic joining of plug connector housings without sacrificing sealing reliability.

An elastic bridge in the connector cage pushes the plug into contact and resists vibration-driven shift to keep signal transmission stable.

A pivoting access panel mechanically blocks high-voltage connector engagement until the junction box is closed, preventing accidental energization.

A movable guide cover shields the connector protrusion from scratches and debris, enabling smooth fitting and blocking foreign matter entry.

Movable control pieces expose the spring clip for wire insertion checks while segmented housing walls preserve airtightness and layout flexibility.

A multicolor indicator lamp distinguishes standby, lighting, and timing modes in LED lamp converters, reducing user confusion.

A gas-venting waterproof member keeps wire seals stable under pressure changes, improving connector waterproofing without tight molding tolerances.

A three-member connector structure fixes the cable and lug securely, improves positioning accuracy, and adds dust and moisture sealing.

Prewired EMT conduit sections with plug-in insulated connectors cut wire pulling, reduce connection errors, and speed commercial building installation.

A recessed fencing groove absorbs glue expansion during soldering, preventing terminal warping while improving connector yield and shielding.

A front sealing member that passes through the outer cover improves waterproofing while preserving connector strength in harsh environments.

A spring-biased access door improves port access while keeping computing device communication ports sealed against water and dust.

An annular seal in a housing groove and a gap-filling seal part simplify connector assembly while maintaining reliable casing sealing.

Rigid magnetic half-shells enclose a cable connector to resist impact, prevent displacement, and improve moisture protection in harsh use.

A sealing ring between the housing and cup-shaped cover blocks water, dust, and corrosion while keeping the plug connection detachable.

A separable conduit seal-off fitting uses brush barriers and a sliding coupler to simplify compound filling, inspection, leak prevention, and retrofit.

An elastic clip passing through the heat sink secures the connector without a sealing sheet, improving heat dissipation and lowering assembly cost.

A mechanical interlock blocks enclosure opening until the connector is removed, reducing shock and arc-flash risk during refrigeration service.

An extended grounding electrode bridges socket gaps in T-connectors, reducing stray capacitance and improving voltage measurement accuracy.

A recessed joint surface relieves thermal shrinkage stress between housing and molded portion, preserving waterproofness and preventing peeling.

A dual-lip annular packing seals the connector cover gap and end surface, improving waterproof and dustproof performance with lower closing force.

Groove projections block sealant flow around the connector, preventing local seal gaps and improving water resistance in housed electronics.

Stepped clearances around the cover opening block capillary water entry, improving waterproofness without enlarging the electronic unit.

Metal protective members reinforce slot ends in a card edge connector, limiting card movement and preventing terminal damage during angled insertion.

Guide holes and rib structures drain splash water away from the connector and PCB, improving ECU waterproofing without complex sealing.
