Abstract

The invention relates to an electrical contact piece having an integrated stop, an L-shaped main contact body having a long and a short arm, the long arm having fastening means for fixing the contact piece in a housing and a bent-out stop piece, and the short arm having an electrical contact surface, and at least one clamping device attached to the long arm of the main contact body for clamping an electrical conductor introduced into the contact piece between a clamping part and the long arm.

Claims (27)

1 . An electrical contact piece having an integrated stop, comprising:

an L-shaped main contact body having a long arm and a short arm, wherein the long arm has fastening means for fixing the electrical contact piece in a housing and a bent-out stop piece and the short arm has an electrical contact surface; and

at least one clamping device attached to the long arm of the L-shaped main contact body for clamping an electrical conductor introduced into the electrical contact piece between a clamping part and the long arm,

wherein the bent-out stop piece is bent out from the L-shaped main contact body such that an insertion depth of an electrical conductor into the electrical contact piece is limited by the bent-out stop piece in such a way that uncontrolled and too-deep insertion is prevented.

2 . The electrical contact piece according to claim 1 , wherein the L-shaped main body further comprises, between the long arm and the short arm, a transition region that has a gradation.

3 . The electrical contact piece according to claim 1 , further comprising two clamping devices attached in parallel on the long arm.

4 . The electrical contact piece according to claim 1 , wherein the at least one clamping device has a contact spring mounted on a clamping holder that is fixed on the long arm by one or more rivets.

5 . The electrical contact piece according to claim 1 , wherein the fastening means for fixing the electrical contact piece in a housing have claws which are designed to hook onto walls of the housing.

6 . An electrical contact device for at least one electrical pole, the electrical contact device comprising:

at least one electrical contact piece according to claim 1 per electrical pole; and

an electrically insulating housing receiving and holding the at least one electrical contact piece.

7 . The electrical contact device according to claim 6 , wherein the housing has a plurality of chambers with a separate chamber for each of the at least one electrical contact piece, and all of the chambers are at least partially electrically insulated from one another.

8 . The electrical contact device according to claim 7 , wherein the housing has two housing halves, at least one chamber for at least one contact piece being provided in each housing half, the chambers of the housing halves being situated opposite each other in an assembled state of the housing halves, and a contact actuation device being able to be arranged between the housing halves and having, per pair of contact pieces situated opposite each other, at least one movable contact bridge for electrically connecting contact pieces situated opposite each other.

9 . The electrical contact device according to claim 8 , wherein the at least one movable contact bridge is held in a first position by restoring means and the contact actuation device has at least one actuating means and holding means which are designed to bring and hold at least one movable contact bridge from the first position to a second position.

10 . The electrical contact device according to claim 8 , wherein the at least one movable contact bridge is linearly movable.

11 . An electrical contact piece having an integrated stop, comprising:

an L-shaped main contact body having a long arm and a short arm, wherein the long arm has fastening means for fixing the electrical contact piece in a housing and a bent-out stop piece and the short arm has an electrical contact surface; and

at least one clamping device attached to the long arm of the L-shaped main contact body for clamping an electrical conductor introduced into the electrical contact piece between a clamping part and the long arm,

wherein the bent-out stop piece is bent out from the L-shaped main contact body such that an insertion depth of an electrical conductor into the electrical contact piece is limited by the bent-out stop piece in such a way that uncontrolled and too-deep insertion is prevented, and

wherein the fastening means for fixing the electrical contact piece in a housing have claws which are designed to hook onto walls of the housing.

12 . An electrical contact device for at least one electrical pole, comprising:

at least one electrical contact piece per electrical pole, the at least one electrical contact piece comprising:

an integrated stop;

an L-shaped main contact body having a long arm and a short arm, wherein the long arm has fastening means for fixing the at least one electrical contact piece in a housing and a bent-out stop piece and the short arm has an electrical contact surface; and

at least one clamping device attached to the long arm of the L-shaped main contact body for clamping an electrical conductor introduced into the at least one electrical contact piece between a clamping part and the long arm,

wherein the bent-out stop piece is bent out from the L-shaped main contact body such that an insertion depth of an electrical conductor into the at least one electrical contact piece is limited by the bent-out stop piece in such a way that uncontrolled and too-deep insertion is prevented; and

an electrically insulating housing for receiving and holding the at least one electrical contact piece, wherein the housing has a separate chamber for each of the at least one electrical contact piece and all the chambers are at least partially electrically insulated from one another.
