Terminal board for fastening electrical lines, and method for fastening electrical lines to a terminal board

1. A terminal board assembly for fastening electrical lines, comprising:

a terminal board having a cut-out therein,

a cylindrical insert inserted into the cut-out of the terminal board and including an end section that projects from a surface area of the terminal board,

a first electrical line including a connecting element, and

a second electrical line including another connecting element,

wherein the cylindrical insert includes a threaded hole so as to fasten the another connecting element of the second electrical line to the terminal board by way of a screw that is screwed into the threaded hole,

wherein the end section of the cylindrical insert is jointed to the connecting element of the first electrical line by way of plastic deformation, and

wherein an electrically conducting connection is established between the connecting element of the first electrical line and the cylindrical insert as a result of plastic deformation.

2. The terminal board assembly according to claim 1 , wherein the plastic deformation is created by at least one of a crimping method, press-fit stemming, and flanging.

3. The terminal board assembly according to claim 1 , wherein an undercut is created between the connecting element of the first electrical line and the insert as a result of the plastic deformation.

4. The terminal board assembly according to claim 1 , wherein the connecting element is designed as a cable lug and includes a cut-out that is adapted to a diameter of the threaded hole.

5. The terminal board assembly according to claim 1 , further comprising a plurality of terminal boards, each having the cut-out, and a plurality of cylindrical inserts, each being inserted into the cut-out and having the threaded hole.

6. The terminal board assembly according to claim 1 , wherein the connecting element includes an opening, the another connecting element includes another opening, and the opening, the another opening, and the threaded hole are arranged to be aligned each other, and

the end section of the cylindrical insert is fit into the opening of the first electrical line through the plastic deformation, and the second electrical line is arranged on the first electrical line to fix the second electrical line to the terminal board through the screw.

7. The terminal board assembly according to claim 6 , wherein the terminal board includes a flange portion having the surface area at a top surface thereof, and the end section projects outwardly from the top surface of the flange portion to be exposed, and

when the screw is screwed in the threaded hole to fasten the second electrical line to the terminal board, the first electrical line and the second electrical line are pressed toward the flange portion.

8. A method for fastening electrical lines to a terminal board, comprising the following steps:

generating a threaded hole in the terminal board by inserting an insert, which includes the threaded hole, into a cut-out of the terminal board;

positioning a connecting element of a first electrical line over the insert of the terminal board;

joining the connecting element and the insert by way of plastic deformation; and

joining another connecting element of a second electrical line to the terminal board by way of a screw that is screwed into the threaded hole.

9. The method according to claim 8 , wherein the insert is used which comprises an end section that projects from a surface of the terminal board and is plastically deformed so as to be joined to the connecting element.

10. The method according to claim 8 , wherein the plastic deformation takes place by at least one of crimping, press-fit stemming, and flanging.

11. A terminal board assembly for fastening electrical lines, comprising:

a terminal board portion having a cut-out therein, and

a cylindrical insert inserted into the cut-out, and including

a cylindrical portion arranged inside the terminal board portion,

an end section formed at one end of the cylindrical portion and projecting outwardly from the terminal board portion,

a threaded hole formed inside the cylindrical insert so that when a screw is adapted to be screwed with the threaded hole, the end section is pressed radially outwardly and adapted to fix one of the electrical lines to the terminal board.
