  • Patent number: 8303352
    Abstract: The contact clip according to the invention comprises a contact portion (11) comprising two elastic blades (15) capable of pressing a male contact portion (2) against an interior cylindrical portion (110) of the said contact portion. In view of the elongate shape of this contact portion, electrical contact between the contact clip and the male contact piece portion is had over a large surface area, thus reducing the contact resistance and the heating when high currents are passed. The contact clip further comprises an attachment portion (10) and possibly an end portion (12) and is intended to be fitted inside a hollow housing of a female contact piece (3).

  • Patent number: 6264508
    Abstract: The contact piece (1) comprises a portion of female type able to accommodate a corresponding portion of male type. This female type portion includes a contact clip (4) provided with elastic fingers (42) oriented towards the opening of a lodging (10) destined to accommodate said male type portion. The piece is completed with a bushing (5) encircling the clip and provided with a front side (50) comprising a passage opening (51) serving as gauge, accepting or refusing the passage of a male portion according to its diameter. In this manner, the elastic fingers (42) always operate in an elastic mode and never suffer a permanent deformation. Such a disposition has many other advantages.
