Radial shielding projections block potting leakage in round plug connectors, protecting the connector face while improving conductor strain relief.

A collar-guided housing connector uses one peripheral seal instead of many line seals, cutting leak points and easing installation troubleshooting.

An elastomeric fold-in seal forms precise internal ribs from easier-to-mold external features, improving FFC connector sealing reliability.

A round built-in connector uses one circumferential seal and a sealless holder to cut leak points and simplify housing assembly and maintenance.

A polyurethane, acrylic ester, or polyolefin elastomer coating protects aluminum-copper joints from galvanic corrosion while stabilizing contact resistance.

A plunger-driven sealant cavity fully encapsulates wire joints to block water, humidity, and corrosives that can cause shorts or grounding.

Continuous hot-air supply and discharge heat shrink tubes faster while the holder maintains positioning without blocking airflow.

A nested sealing ring, O-ring, and biasing unit keep a USB-C module sealed during use while easing tolerance and assembly constraints.

Temperature-tuned sealing viscosity helps a heat-shrink wire connector fill gaps, resist water intrusion, and stay durable at high temperatures.

Uncured plastic is pressed over the connector opening and cured in place, while an insulating protective member shields terminals and avoids custom dies.

Movable, foldable cantilevers with multiple fixtures let one heat shrink machine clamp spliced, crimped, and multi-tube wire harnesses.

Movable cantilevers with multiple fixtures clamp spliced, crimped, and other wire harnesses, then fold away to save heat shrink machine space.

A two-part reusable enclosure replaces tape to shield cable connectors from dust, debris, and water without sticky residue.

Sealed power and signal modules isolate EMI and resist vibration, helping automotive connectors stay mated and preserve signal integrity.

A horizontal-axis conveyor wheel feeds and positions spouts in less space, enabling compact modules and quick nozzle variant changeovers.

A split enclosure replaces electrical tape to shield cable connectors from dust and water while avoiding sticky residue and enabling reuse.

A bias-loaded USB-C module uses dual sealing rings and an intermediate housing to improve waterproof sealing and ease assembly.

A stacked plastic-and-sealant seal closes channel openings to block contaminants and preserve DDR5-class signal integrity over time.

A lever-driven interface pushes an elastic sleeve off a reusable holdout tube, cutting waste, mounting effort, and cable damage risk.

Dual potting reservoirs linked by a wall passage simplify resin injection and improve waterproofing in downsized signal connectors.

A visual fill indicator in a recessed potting reservoir helps small connectors receive the right sealant volume for reliable waterproofing.

Two solid cores and a PET film cut cold shrink removal force while helping mastic form a reliable moisture seal on cable splices.

An EDM-roughened inner shell anchors an adhesive seal to block water ingress while cutting molded-seal cost and mounting constraints.

A rigid-flexible wire seal assembly limits longitudinal compression while preserving lateral sealing, keeping connector terminals aligned and engaged.

Segmented clamp members and guided hot-air paths keep shrink tubes stable while improving heating speed and uniform shrinking.

By creating a gas-free interface around conductors and contacts, this connector housing prevents triple-point discharge and improves HV connection reliability.

Two solid cores and a PET film cut removal force and repetitive motion while trapping mastic to form a waterproof cable splice seal.

Coaxial chambers pre-position connector parts so a cable can pass through in sequence, cutting manual errors and assembly time.

A nested conductor-insulator-housing feedthrough uses dielectric fluid and a movable contact to deliver subsea power under high pressure with less maintenance.

A stiff internal grid with softer outer layers limits seal deformation during cable insertion while maintaining moisture and dirt sealing.

Segmented sheath prevents inward deformation under stopper pressure, resolving uneven sealing and water ingress issues in flat cables.

An overlapped sheet member prevents elasticity recovery detachment in connector wires, ensuring long-term waterproof reliability.

Front member assembly forms the fitting recess to eliminate radial mold parting lines and burrs that reduce sealing performance.

Segmented sealing elements engage between a protection device and connector to isolate cables from environmental factors while simplifying the assembly process.
