Problems solved by technology

[0004] The disadvantage of this cable connector is that two separate parts (contact spring plus power spring) have to be manufactured and assembled, and the range of diameters of the cable conductors that can be safely contacted by the cable connector is rather limited

Embodiment Construction

[0050] figure 1 A perspective view of a cable connector 19 with a cable 1 having a cable conductor 2 and a cable insulation 3 according to the invention is schematically shown. The cable connector 19 is a cutting clamp connector 19 designed as an insulation displacement connector 20 (IDC). The cable connector 19 has two legs 190 whose ends form a slot 192 . The cable 1 can be inserted into the slot 192 through the insertion opening 196 , which also functions as a cutting element for removing the insulation 3 . When the cable conductor 2 contacts the leg 190 , the cable conductor 2 reaches the contact position and is held in the contact position by the force applied to the conductor 2 via the leg 190 . The force is figure 1 is symbolized as two empty arrows in . It is substantially perpendicular to the direction of movement M of the cable during insertion. The cable 1 is shown with dotted lines before the insulation 3 is cut and before the cable is in contact position. Th...

Abstract

The cable connector (19) for making an electrical contact with a cable conductor (2) of a cable (1) comprises two legs (190), at least one of which can make electrical contact with a cable conductor (2) inserted into the cable connector (19) into a contacting position, and the two legs (190) are capable of exerting a contacting force on a cable conductor (2) in the contacting position for holdingthe cable conductor (2) in the contacting position. When there is no cable (1) inserted in the cable connector (19), the legs (190) exert an non-vanishing initial force on each other. In other words,the cable connector has two prestressed legs. Ends of the legs press against each other with some force prior to the insertion of any cable into the connector. The cable connector can, e.g., be used as an insulation displacement connector and in connector terminal blocks. Methods for manufacturing such a cable connector (19) comprise methods, in which an elastic deformation in at least one sectionofthe cable connector (19) is performed, while another section of the cable connector (19) is plastically deformed. Preferably, the cable connector is integrally made from one piece of bent sheet metal .

Description

technical field [0001] The present invention relates to the field of low voltage cable connections and cable connectors, and in particular to clamping contacting elements, insulation displacement connectors and connector terminal blocks and methods of manufacture thereof. It relates to methods and devices according to the opening clauses of the claims. Such devices find application, for example, in industrial cabinets or in residential installations. Background technique [0002] Such a low voltage cable connector is known from published European patent application EP 0 893 845 A2. The connector is an insulation displacement connector (IDC), ie a connector that does not require the cable insulation to be stripped before making the connection to the cable conductors. The IDC has a contact spring with two spring legs for contacting the cable. The insulation of the cable inserted into the IDC is cut through by means of the leg so that the cable conductor ends up in the open ...
