Connections Effected By Permanent Deformation TRIZ Cases

Spot friction stir welding laterally bonds copper contacts to aluminum cable strands, improving joint strength while lowering connector cost.

Mechanical splices with asymmetric serrated tines crimp flat magnetic wires without soldering, improving connection stability and process speed.

Crimping followed by induction heating melts strand insulation in place, creating faster, safer, and more reliable Litz wire connections.

An integral sidewall and stress-relief coupling structure helps pre-crimped terminals resist bending as terminal fittings are miniaturized.

An inclined guide on the sliding terminal enlarges the wire entry path, easing insertion of small or large core wires without changing the housing.

An auxiliary sleeve in a radial press forms a burr-free metal sheath with close contact, strong heat transfer, and low overload risk.

Bendable terminal wings create direct contact and secure retention for planar conductors, reducing assembly steps and connection complexity.

Angled branch entry and a distributed trunk bus replace combiner boxes to simplify solar string wiring, cut material use, and improve connection reliability.

A transverse groove in the crimp terminal protrusion anchors the core wire, limiting loosening while maintaining stable electrical contact.

A conical insertion hole and heat-shrink tube prevent insulation crimping, lower resistance, and reduce corrosion risk in copper-aluminum joints.

A support sleeve preserves contact pressure in multi-wire crimp joints, improving contact stability and reducing coating-dependent processing.

A protruded transition section between wire and insulation barrels absorbs vibration and protects small-diameter core wire crimps.

A resilient locking guide lets stacked terminals self-position during assembly, cutting parts, preventing misalignment, and saving time.

A widened serration opening and shallower swage-piece grooves keep crimp serrations stable, lowering contact resistance and improving wire connection.

A base bore, lay-in slot, and plug compress conductors axially to create secure grounding connections that can be expanded without replacing existing hardware.

A multi-part contact carrier holds crimp contacts and a Y-shaped shield to enable on-site hybrid plug assembly with durable low-resistance conductivity.

Pointed piercing teeth cut through main and tap wire insulation to create secure multi-wire splice connections with simpler installation.

Segmented guide and abutment ribs improve terminal positioning and bolt fastening while helping detect misassembly and maintain sealing.

A magnetic ground clamp attachment creates a reliable conductive path on epoxy-coated pipes, preventing arcing and improving weld quality.

A two-zone wire connector secures metallic wires to PCBs by winding on a pre-mounting section, then pressing onto a final contact region.

A probe-access wire nut uses a top opening, metal ball, and spiral thread to test continuity and electrical parameters without disassembly.

A sliding pressurizing portion crimps the wire without large facilities, while a restricting portion prevents terminal bending.

Inward folded outer-conductor projections keep the shield close to the coated wire, limiting impedance change without cracking or larger connectors.

Insert holes in the shield ring sandwich the braided part, improving binding strength without increasing the ring width.

An elastic terminal piece sandwiches core wires to prevent breakage during connection.

Integrating the guide arm into the metal contact cage eliminates complex insulator fabrication while maintaining reliable conductor guidance.

Inclined standing piece distal ends guide the round terminal into precise alignment, preventing deformation during bolt tightening.

Embossed press joint with coating material forms intermetallic phase to reduce microcracking and electrical resistance in dissimilar material connections.

Machined tubular elements form electrodes and deflectors within an elastomeric sleeve.

Staggered cylindrical recesses tear oxide coatings and distribute force to stabilize electrical resistance and mechanical strength.
