Doublepin

Doublepin is a term used in multiple technical domains to denote components or configurations that incorporate two pins. The exact meaning varies by context, but common thread is a dual-pin arrangement that provides alignment, redundancy, or a simple connect/disconnect action.

In electrical and electronic contexts, a doublepin connector refers to a connector with two conductive pins. Such connectors are used for low-power signaling, power delivery, or as simple removable interconnects. They are specified by pin diameter, pitch, current rating, and housing style, and may be gendered (receptacle and plug) or paired as a plug-in module. The two pins can carry separate signals or one power and one ground line.

In mechanical engineering and manufacturing, a doublepin joint or fastener uses two parallel pins to secure parts together. This arrangement improves rotational alignment and resists lateral shear as compared to a single pin. Applications include hinges, linkages, and couplings, where pins may be perpendicular to the joint plane and retained by clips, cotter pins, or retaining rings. Materials range from steel to stainless alloys depending on load and environment.

In other uses, the concept appears in fixtures and modular assemblies where a two-pin configuration defines a mating interface or a guiding alignment feature.

The term doublepin is not universally standardized across industries; spec sheets and engineering drawings should define pin size, spacing, load ratings, retention method, and compatibility to avoid ambiguity.
