Abstract

A connecting element for mounting an electrical circuit board to an electrical flat conductor, in particular a busbar, has a flat or substantially flat mounting surface for applying and mounting the connecting element to the circuit board, and a tulip contact for receiving the flat conductor in an electrically contacting manner. The tulip contact includes at least one clamping element and a support element, between which a receptacle for the flat conductor is provided, and wherein the tulip contact preferably extends at a mounting angle greater than 45° and less than 135° with respect to the mounting surface. An electrical circuit board having such a contact element, a terminal block having such an electrical circuit board, and a method for automated mounting of such a terminal block are also provided.

First claim

The invention claimed is:

1. A connecting element, comprising
(a) a flat mounting portion configured for mounting on a circuit board; and
(b) a tulip contact extending at a mounting angle greater than 45° and less than 135° relative to said mounting portion and configured to receive a flat conductor in an electrically contacting manner, said tulip contact including at least one clamping element which extends in a sliding direction relative to the flat conductor and a support element which extends in a direction against the sliding direction between which a receptacle for the flat conductor is defined, a free end of said clamping element extending from said mounting portion at the mounting angle.

2. A connecting element as defined in claim 1 , wherein said support element includes a free end which extends from said mounting portion at the mounting angle.

3. An electrical circuit board including the at least one connecting element as defined in claim 1 .

4. An electrical circuit board as defined in claim 3 , wherein said mounting portion of each connecting element lies flat against the circuit board.

5. A connecting element, comprising
(a) a flat mounting portion configured for mounting on a circuit board;
(b) a tulip contact configured to receive a flat conductor in an electrically contacting manner and including at least one clamping element which extends in a sliding direction relative to the flat conductor and a support element which extends in a direction against the sliding direction between which a receptacle for the flat conductor is defined; and
(c) a connecting arm extending from said mounting portion opposite said support element, said connecting arm extending above and spaced from a free end of said support element, said at least one clamping element extending from said connecting arm.

6. A connecting element as defined in claim 5 , wherein said at least one clamping element extends resiliently from said connecting arm.

7. A connecting element as defined in claim 5 , wherein at least two clamping elements are arranged side by side on said connecting arm.

8. A connecting element as defined in claim 5 , wherein said connecting arm has a rectangular cross-sectional shape.

9. A connecting element as defined in claim 5 , wherein an outer surface of said connecting arm is configured for fastening to an automation robot.

10. A connecting element as defined in claim 5 , wherein said mounting portion, said connecting arm and said at least one clamping element are manufactured from an electrically conductive flat strip material as a stamped and bent component.

11. A connecting element, comprising
(a) a flat mounting portion which contains a through-hole for mounting on a circuit board; and
(b) a tulip contact configured to receive a flat conductor in an electrically contacting manner and including at least one clamping element which extends in a sliding direction relative to the flat conductor and a support element which extends in a direction against the sliding direction between which a receptacle for the flat conductor is defined.
