Custom Wire Harness Assemblies

 

Y.C. Cable manufactures custom wire harness assemblies for OEM, industrial, automotive, medical, automation, and electronic equipment applications.

 

A wire harness organizes wires, cables, terminals, connectors, protective materials, labels, and mounting features into a defined routing configuration. Each harness is manufactured according to customer-approved drawings, BOMs, wiring diagrams, branch dimensions, pinouts, and testing requirements.

 

Wire Harness Configurations

Wire harness assemblies can range from simple point-to-point wiring to complex multi-branch configurations.

Typical configurations may include:

• Point-to-point harnesses

• Multi-branch harnesses

• Power distribution harnesses

• Signal and control harnesses

• Sensor and actuator harnesses

• Internal equipment wiring

• Panel and cabinet wiring

• Board-to-wire harnesses

• Combined power and signal configurations

• High-density wiring configurations

 

Routing & Branch Requirements

Wire harness design should consider how the harness will be installed and serviced within the finished equipment.

Important requirements may include:

• Main harness length

• Branch lengths

• Breakout locations

• Connector orientation

• Wire routing

• Service loops

• Bend radius

• Mounting points

• Clips and fasteners

• Separation of power and signal wiring

• Installation and maintenance access

• Protection from moving or sharp components

 

Connectors, Terminals & Components

Wire harness assemblies may incorporate:

• Customer-approved connectors

• Crimp terminals

• Soldered terminations

• Splices

• Junctions

• Grommets

• Boots

• Clips

• Mounting components

• Labels

• Wire markers

• Heat-shrink identification

• Protective sleeves and tubing

All materials should follow the approved product documentation and project requirements.

 

Harness Protection & Identification

Protective and identification materials may include:

• Braided sleeving

• Protective tubing

• Conduit

• Wire loom

• Heat-shrink tubing

• Tape

• Grommets

• Boots

• Labels

• Wire markers

• Connector identification

• Branch identification

Material selection depends on installation, environmental, mechanical, and customer requirements.

Inspection & Testing

Testing and inspection should follow the approved product requirements.

Depending on the project, these may include:

• Pin-to-pin verification

• Electrical continuity testing

• Connector and terminal verification

• Visual workmanship inspection

• Dimensional verification

• Pull-force testing when specified

• Insulation resistance or Hi-Pot testing when specified

• First-article inspection

• Customer-defined functional testing

 

Wire Harness vs. Cable Assembly

A wire harness typically organizes multiple wires or cables into defined routes and branches using connectors, terminals, protective coverings, labels, and mounting features.

A cable assembly may use multi-conductor cable, shielding, molded connector protection, or other features as part of a finished connection.
