News

JIAXING NT ELECTRONIC TECHNOLOGY CO., LTD. is a China-based Electronic Wire Harness manufacturer supplying custom internal and external connection harnesses for consumer electronics, home appliances, office equipment, wearables, drones, and smart terminal devices. Our range covers jumper wires, battery connection leads, charging cables, switch and terminal harnesses, ribbon cables, and multi-branch assemblies, built to match device geometry, connector specifications, and electrical parameters.

We work from concept review and sample development through mass production, so a harness that starts as a drawing or a physical sample becomes a stable, repeatable part in your build. Our Jiaxing facility and Ho Chi Minh City factory support both custom projects and repeat volume orders.

Our Electronic Wire Harness Range

Electronic wire harnesses sit outside the dedicated automotive, medical, and industrial categories, covering the broad field of internal and external connection cables used across electronic terminals and systems. The product types below show where each assembly fits.

Switch & Terminal Harnesses

Metal push-button switches, rocker switches, and indicator-light assemblies terminated to XH, PH, or spade connectors for control panels and equipment interfaces.

Battery & Power Leads

High-current battery connection harnesses with Amass, EC5, and fuse-box options, plus sheathed multi-core power leads with spade terminals.

Board-to-Board & Ribbon Cables

PH2.0 single-end rainbow ribbon harnesses, XH multi-pin splitters, and twisted-pair control leads for internal device wiring.

Ground & Ring Terminal Assemblies

HB 4-pin to O-type ring ground harnesses and L-shaped 6.3mm spade-to-pin insulated connectors for chassis and enclosure grounding.

Adjacent categories in our Products range include Automotive & EV Wire Harness, Industrial Control Cables, and Medical Wire Harness; electronic harnesses often share materials and connector families with these lines.

Application Fit by Product Type

Harness Type Typical Application Key Configuration Points
Switch & indicator harness Control panels, machine tools, security devices Switch housing color, light color/brightness, harness length, terminal type
Battery connection harness Power tools, chargers, energy storage, e-mobility Connector series (Amass, EC5), fuse box, wire gauge, length
Sheathed multi-core lead Home appliances, lighting, power adapters Core count, conductor cross-section 0.5–2.5mm², sheath material, spade size
Ribbon & splitter harness Internal board wiring, sensor fan-out, LED modules Pin count, pitch (PH2.0, XH2.54), branch count, twist option
Ground & ring terminal harness Chassis grounding, enclosure bonding, power distribution Ring diameter, insulation style, wire gauge, terminal plating

Materials and Critical Specifications

Conductor, insulation, and terminal choices determine how a harness performs in bending, heat, and vibration. We select these against the working current, voltage, temperature, and routing environment of each device.

  • Conductors: stranded copper, with cross-sections commonly from 0.5mm² to 2.5mm² for multi-core power and signal leads; larger gauges for high-current battery connections.
  • Insulation and sheath: PVC, TPE, silicone, or polyurethane, selected for flame retardance, abrasion resistance, flexibility, and aging resistance.
  • Terminals: copper alloy spade, ring, and pin terminals with tin or nickel plating for conductivity and oxidation resistance; fully insulated, semi-insulated, or bare options.
  • Connectors: XH2.54, PH2.0, Molex 5557, Amass LCC30-F, EC5, HB 4-pin, and other standard families matched to mating method and insertion frequency.
  • Shielding and jacketing: shielded and coaxial constructions where signal integrity or EMI control is required.

Configuration and OEM/ODM Engineering

Our OEM/ODM service starts from either complete drawings and BOM files or an initial concept, performance target, or application idea. Engineering reviews harness routing, branch structure, fixing method, and connector layout against installation space and assembly path, then matches wire, insulation, and terminals to the electrical and environmental requirements.

Where protection or integration is needed, we support overmolding and low-pressure molding, plus multiple cable and harness assembly processes. Packaging, labeling, and shipment requirements are planned with the harness design so that samples and mass-production batches arrive ready for your line.

Manufacturing and Quality Control

Our Jiaxing facility covers approximately 10,000 square meters with production lines organized by product category, supported by automated wire harness equipment and injection molding equipment. The process sequence runs from wire extrusion and cutting through stripping, crimping or welding, sub-assembly, overmolding, harness assembly, inspection and testing, and packing.

  • Continuity and conductor resistance checks on assembled harnesses.
  • Insulation resistance and withstand voltage testing for power-carrying leads.
  • Terminal pull-force and crimp-height verification.
  • Visual inspection of sheath, terminal plating, and connector seating.
  • Durability testing on switch assemblies, including press-cycle life tests.

Our quality system is supported by IATF 16949 and ISO 14001 certification, and our wire harnesses are covered under UL certification (ZPFW8.E502461). Certification evidence can be supplied with project documentation where required.

Prototyping, Volume Production, and Delivery

We support small-batch sample validation and high-mix flexible production alongside volume orders. Sample lead time is typically 15–25 days, with bulk orders running around 3–4 weeks, and shipment can be arranged from Shanghai or Vietnam. Minimum order quantities vary by product; many catalog harnesses start at 1000 pieces, while selected items are available from 500 pieces.

Dual-location manufacturing in China and Vietnam gives overseas projects an alternative supply path and helps with delivery flexibility for European and American customers.
