ELECTRICALLY-CONDUCTIVE CONNECTIONS; STRUCTURAL ASSOCIATIONS OF A PLURALITY OF MUTUALLY-INSULATED ELECTRICAL CONNECTING ELEMENTS; COUPLING DEVICES; CURRENT COLLECTORS

Introduced: September 1968

Description

H01R encompasses electrical connection devices and systems that establish conductive pathways between electrical components. This subclass covers connectors, coupling devices, plugs, sockets, terminal assemblies, and current collectors used across diverse applications from consumer electronics to industrial equipment. It includes technologies for organizing and insulating multiple electrical conductors within a single connector body, as well as mechanisms for reliable and repeated connection/disconnection of circuits. Adjacent classes H01M (electrochemical devices) and H01G (capacitors) are excluded; H01R focuses specifically on mechanical and structural aspects of electrical connections rather than energy storage or conversion devices.

Of 25 combined children, 16 exist in both systems.

5 codes are CPC-only extensions, 4 exist only in IPC.

Note: 5 CPC extensions are marked as secondary classification only.

9 shared codes have differing titles between IPC and CPC.
