Abstract

Abstract For a contact element with a screw-type terminal for electric conductors, wherein the contact element comprises a conductor connection part provided with a bore, into which the conductor is insertable and clampable by means of a screw insertable at right angles to the bore and/or conductor into a threaded bore in the conductor connection part, and wherein between the end of the screw directed towards the conductor and the conductor a wire protection plate is provided in the bore, it is proposed to make the wire protection plate substantially L-shaped, an angled foot thereby being formed, to insert the wire protection plate into the bore in such a way that the foot is situated at the base of the bore, and to provide the foot with lateral, barb-like mouldings which, upon insertion of the wire protection plate, dig into the wall of the bore.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 226 words
A contact element with a screw-type terminal for electric conductors, wherein the contact element comprises a conductor connection part provided with a bore, into which the conductor is insertable and clampable by means of a screw insertable at right angles to the bore and/or conductor into a threaded bore in the conductor connection part, and wherein between the end of the screw directed towards the conductor and the conductor a wire protection plate is provided in the bore, characterized in that the wire protection plate ( 9 ) is substantially L-shaped and comprises an angled foot ( 11 ), that the wire protection plate ( 9 ) is inserted into the bore ( 6 ) in such a way that the foot ( 11 ) is situated at the base of the bore, and that the foot ( 11 ) is provided with lateral, barb-like mouldings ( 12 ) which, upon insertion of the wire protection plate ( 9 ), dig into the wall of the bore ( 6 ), wherein the insertion region ( 17 ) of the bore ( 6 ) is flared in a tulip-like manner, and the upper end ( 15 ) of the limb ( 10 ) of the wire protection plate ( 9 ) is provided with a correspondingly shaped, outwardly directed curvature which lies on the flared insertion region.
Claim 2
Dependent Claim 226 words
A contact element with a screw-type terminal for electric conductors, wherein the contact element comprises a conductor connection part provided with a bore, into which the conductor is insertable and clampable by means of a screw insertable at right angles to the bore and/or conductor into a threaded bore in the conductor connection part, and wherein between the end of the screw directed towards the conductor and the conductor a wire protection plate is provided in the bore, characterized in that the wire protection plate ( 9 ) is substantially L-shaped and comprises an angled foot ( 11 ), that the wire protection plate ( 9 ) is inserted into the bore ( 6 ) in such a way that the foot ( 11 ) is situated at the base of the bore, and that the foot ( 11 ) is provided with lateral, barb-like mouldings ( 12 ) which, upon insertion of the wire protection plate ( 9 ), dig into the wall of the bore ( 6 ), wherein the insertion region ( 17 ) of the bore ( 6 ) is flared in a tulip-like manner, and the upper end ( 15 ) of the limb ( 10 ) of the wire protection plate ( 9 ) is provided with a correspondingly shaped, outwardly directed curvature which lies on the flared insertion region.
Claim 3
Dependent Claim 58 words
Contact element according to claim 1 , characterized in that the limb ( 10 ) of the wire protection plate ( 9 ) adjoining the foot ( 11 ) comprises an embossed reinforcing bead ( 14 ), and that the transition ( 13 ) from the foot ( 11 ) to the limb ( 10 ) is rounded.
Claim 4
Dependent Claim 28 words
Contact element according to claim 1 , characterized in that the front end of the screw ( 8 ) is provided with a hemispherical tip ( 16 ).
