Define the harness architecture and verification plan before comparing an assembly approach. Use the controlled drawing, actual operating conditions, and approval requirements. Contents Part 1. What should an electrical test plan prove? Part 2. How does continuity testing fit the sequence? Part 3. When is hi-pot or insulation testing relevant? Part 4. What does contact […]

Define the harness architecture and verification plan before comparing an assembly approach. Use the controlled drawing, actual operating conditions, and approval requirements. Contents Part 1. What defines a wire harness branch? Part 2. When does an inline splice fit the branch? Part 3. When should a junction be specified? Part 4. How do breakouts change […]

Define actual assembly, fixture, service, and repair cycles before selecting a fine-pitch interface. Use the drawing, intended operating conditions, and validation plan before comparing component options. Contents Part 1. Why should mating cycles be a design input? Part 2. Which operating scenarios create the most wear? Part 3. How do alignment and retention affect durability? […]

Treat the connector footprint, mating geometry, reference path, and intended signaling as one design review. Use the drawing, operating conditions, and validation plan before comparing component options. Contents Part 1. What signal-integrity risks change with a small pitch connector? Part 2. How should the interface and return path be defined? Part 3. Where do impedance […]

Sizing a crimp splice connector means confirming the conductor, insulation, barrel, die, and finished installation work as one controlled combination. Wire gauge is an important starting point, but it is not enough by itself. Strand construction, insulation diameter, transition-wire conditions, tool profile, and inspection access can all change whether a nominally similar splice is appropriate. […]

A butt splice is selected when two conductors must become one continuous, controlled inline connection; a terminal splice is the broader category that can include that same join and other conductor-to-conductor formats. The decision should begin with the wire and the installation environment, then move to insulation, tool access, inspection, and the release requirements. It […]
