A self-clamping electrical connector or terminal block is disclosed having one or more entrance passages for inserting a corresponding number of conductive cores of leads. A U-shaped metal guide member is mounted in the housing and a leaf spring part with a corresponding number of leaf springs each having an angled portion extending between the legs of the guide member. The angled portion is adapted to clamp the conductive core against one of the legs upon insertion of the lead. Each leaf spring comprises clipping means including a bowed portion connected to the angled portion and a flat portion. The bowed portion bears on the inner surface of the other leg of the guide member and the flat portion bears against the outer surface of said other leg. A lug may be provided on the leg to prevent the leaf spring part from slipping off the guide member.
A self-clamping electrical connecting device comprising an insulating housing, at least one entrance passage for inserting a conductive core of a lead, a U-shaped metal guide member, and a leaf spring member having a portion angled with respect to the axis of said entrance passage and extending between legs of said U-shaped guide member, said angled portion of said leaf spring member being adapted to clamp upon insertion the conductive core of the lead against one of the legs of said guide member, said leaf spring member comprising resilient clipping means extending around the free end of the other leg of said guide member and bearing on the inner and outer surfaces thereof.
A self-clamping electrical connecting device comprising an insulating housing, at least one entrance passage for inserting a conductive core of a lead, a U-shaped metal guide member and a leaf spring member having a portion angled with respect to the axis of said entrance passage and extending between legs of said U-shaped guide member, said angled portion of said leaf spring member being adapted to clamp upon insertion the conductive core of the lead against one of the legs of said guide member, said leaf spring member comprising resilient clipping means including a bent over resilient portion for clipping said leaf spring member on the other leg of said guide member, a fulcrum zone being formed between the angled portion and the bent-over resilient portion, said fulcrum zone bearing against the inner surface of said other leg, and said bent-over resilient portion comprising a flat part bearing against the outer surface of said other leg.
