Clamping Device For Connecting A Conductor Without Stripping The Insulation

A clamping device for connecting a conductor (50) without stripping its insulation, the clamping device having a housing (14) and an actuating part (22) mounted to pivot between a receiver position and a contact position, the housing including a duct (26) to receive the conductor (50) with which contact is to be established, and also a blade contact (18.1) that includes a rear web (32) and two spring legs (36) with end sections (44) bent toward each other that are adjacent to each other along a slot (42) and include contact blades (48) extending to the slot (42) which, when the actuating part (22) is transferred into the contact position, presses into its duct (26) and comes into contact with the conductor (50) contained within it after cutting through its insulation, and with a second contact part (18.2) to route the current path from the blade contact (18.1) out of the housing (14), which is in electrical contact with the blade contact (18.1), whereby the blade contact (18.1) and the second contact part (18.2) are formed as a single unit and whereby the rear web (32) of the blade contact (18.1) possesses a section (32.1) that is elongated over connection areas of the spring leg (36) from whose longitudinal sides spring arms (34) are bent that together with their ends are shaped into a contact tube or tulip contact (40).

A clamping device as in claim 12, wherein when viewed longitudinally along the rear web (32), the spring legs (36) of the blade contact (18.1) are wider than the spring arms (34) of the second contact part (18.2), and their cross section diminishes from the rear web (32) toward the contact blades (48).

A clamping device as in claim 12, wherein the spring arms (34) of the second contact part (18.2) possess a cross section that diminishes from the rear web (32) to a contact tube or tulip contact (40).

A clamping device as in claim 12, wherein the spring arms (34) of the second contact part (18.2) are angled from the rear web (32) in the direction opposite to the spring legs (36) of the blade contact (18.1).

A clamping device as in claim 12, wherein the spring arms (34) of the second contact part (18.2) are angled in the same direction as the spring legs (36) of the blade contact (18.1) from the rear web (32), whereby the contact blades (48) are located on those edges of the spring legs (36) of the blade contact (18.1) that rest at the side of the blade contact (18.1) adjacent to which the spring arms (34) of the second contact part (18.2) are located.

A clamping device as in claim 12, wherein the housing (14) includes an inner chamber (16) and an aperture (16.1) in its one sidewall (16.2) to receive the contact elements (18), whereby the inner chamber (16) and the aperture (16.1) are matched to the contour of the contact element (18) surrounding both ends of the rear web (32).
