Clamping element
View Patent ↗A clamping element for fastening an electrical conductor to a printed circuit board, by which electrically conductive connection between the electrical conductor and the printed circuit board is produced. In order to achieve an inexpensive and completely automatable possibility for connection between electrical conductors and printed circuit boards, the clamping element is in the form of a stamped sheet-metal part and has at least two clamping wings and one clamping web, which is arranged between the clamping wings. The clamping web is capable of being bent in such a way that the clamping wings clamp in the conductor. At least one securing claw is formed on the clamping wings. The securing claw can be pressed into the printed circuit board.
1. A clamping element for fastening an electrical conductor to a printed circuit board, an electrically conductive connection being produced by the clamping element between the electrical conductor and the printed circuit board, the clamping element comprising:
a stamped sheet-metal part including at least two clamping wings and one clamping web arranged between the clamping wings, the clamping web being bendable such that the clamping wings clamp in the conductor; and
at least one securing claw protruding from an edge of at least one of the clamping wings such that the securing claw is pressable into the printed circuit board by bending back the clamping web.
2. The clamping element as claimed in claim 1 , wherein the clamping wings have a conductor pocket configured to surround the conductor.
3. The clamping element as claimed in claim 1 , wherein the clamping wings have a clamping wing arch configured to mount the conductor in a sprung manner.
4. The clamping element as claimed in claim 1 , wherein the clamping wings have a contact face.
5. A fastening system for an electrical conductor on a printed circuit board, comprising:
the clamping element as claimed in claim 1 ; and
a receiving element with an electrically conductive surface formed on the printed circuit board, the clamping element being configured to be insertable into said receiving element.
6. The fastening system as claimed in claim 5 , wherein the receiving element is U-shaped.
7. A method for fastening an electrical conductor on a printed circuit board, comprising:
clamping the electrical conductor into a clamping element for fastening an electrical conductor to a printed circuit board, an electrically conductive connection being produced by the clamping element between the electrical conductor and the printed circuit board, the clamping element having: a stamped sheet-metal part including at least two clamping wings and one clamping web arranged between the clamping wings, wherein the clamping web is capable of being bent in such a way that the clamping wings clamp in the conductor; and at least one securing claw formed on the clamping wings, the securing claw being capable of being pressed into the printed circuit board, by bending back the clamping web; and
clamping the electrical conductor in between the clamping wings of the clamping element, whereupon the clamping element is pushed into a receiving element, and whereupon the securing claw is one of pressed and driven into the printed circuit board.
