Note(s)

  1. This sub-class deals with all kinds of contact-making disconnectible and non-disconnectible electric line connectors, coupling devices, lamp or similar holders or current collectors for all kinds of electric lines, cables or apparatus. Mounting of connections in or on specified apparatus is classified in the sub-class for such apparatus, e.g. mounting in junction or distribution boxes is classified in sub-class H02B or H02G, high-temperature connections for heating elements in group H05B 3/08. Structural association of one part of a two-part coupling device with specific electric apparatus is classified with the apparatus, e.g. association of cap with incandescent lamp is classified in sub-class H01K.
  2. In this sub-class, a contact in a coupling device is only regarded as an additional earth contact if this contact is clearly designed for that purpose. General details are classified in groups H01R 5/00, H01R 7/00, H01R 9/00 or H01R 11/00.
