Electrical contact element and contact arrangement

1. An electrical contact element, comprising:

a plate member with a contact slot configured to receive an electrically insulated conductor, the plate member having first and second plate arms extending there from that delimit the contact slot; and

at least one substantially triangular retaining element extending from a plane of the plate member configured to secure the electrical contact element in a housing, the retaining element having first and second retaining surfaces arranged at a fixed angle to each other of less than 180 degrees, the first retaining surface being arranged parallel to a longitudinal axis of the contact slot and the second retaining surface being arranged perpendicular to the longitudinal axis of the contact slot.

2. The electrical contact element of claim 1 , wherein the retaining element is an embossment.

3. The electrical contact element of claim 1 , wherein the plate member includes two of the retaining elements, the retaining members being symmetrically arranged with respect to the longitudinal axis of the contact slot.

4. The electrical contact element of claim 1 , wherein the first and second retaining surfaces are connected in a connecting region, the first and second retaining surfaces being inclined and having a maximum height from a surface of the plate member in the connecting region.

5. The electrical contact element of claim 1 , wherein the plate member has a substantially triangular opening adjacent to the retaining element.

6. The electrical contact element of claim 1 , further comprising a second plate member arranged substantially parallel to the plate member, the second plate member being connected to the plate member by at least one connecting strip.

7. The electrical contact element of claim 6 , wherein the second plate member has a contact slot arranged parallel to the contact slot of the plate member that is configured to receive an electrically insulated conductor, the second plate member having first and second plate arms extending there from that delimit the contact slot of the second plate member.

8. The electrical contact element of claim 6 , further comprising a spring contact that extends from the plate member.

9. The electrical contact element of claim 6 , wherein the second plate member has at least one retaining element extending from a plane of the second plate member.

10. A contact arrangement, comprising:

an electrical contact element including a plate member with a contact slot configured to receive an electrically insulated conductor, the plate member having first and second plate arms extending there from that delimit the contact slot;

at least one substantially triangular retaining element extending from a plane of the plate member configured to secure the electrical contact element in a housing, the retaining element having first and second retaining surfaces arranged at a fixed angle to each other of less than 180 degrees, the first retaining surface being arranged parallel to a longitudinal axis of the contact slot and the second retaining surface being arranged perpendicular to the longitudinal axis of the contact slot; and

a housing having a contact accommodating chamber that receives the electrical contact element, the contact accommodating chamber having first and second conductor receiving openings and a wall, the retaining element engaging the wall when the electrical contact element is positioned in the contact accommodating chamber.

11. The contact arrangement of claim 10 , wherein the retaining element is an embossment.

12. The contact arrangement of claim 10 , wherein the plate member includes two of the retaining elements, the retaining members being symmetrically arranged with respect to longitudinal axis of the contact slot.

13. The contact arrangement of claim 10 , wherein the housing is made of a flexible plastic material.

14. The contact arrangement of claim 10 , wherein the retaining element penetrates the wall of the housing.

15. The contact arrangement of claim 10 , wherein the housing includes support edges that abut stop elements on the electrical contact element that fix the electrical contact element at a maximum insertion depth.

16. The contact arrangement of claim 10 , wherein the first and second retaining surfaces are connected in a connecting region, the first and second retaining surfaces being inclined and having a maximum height from a surface of the plate member in the connecting region.

17. The contact arrangement of claim 10 , further comprising a second plate member arranged substantially parallel to the plate member, the second plate member being connected to the plate member by at least one connecting strip.

18. The contact arrangement of claim 17 , wherein the second plate member has a contact slot arranged parallel to the contact slot of the plate member that is configured to receive an electrically insulated conductor, the second plate member having first and second plate arms extending there from that delimit the contact slot of the second plate member.

19. The contact arrangement of claim 17 , further comprising a spring contact that extends from the plate member.

20. The contact arrangement of claim 17 , wherein the second plate member has at least one retaining element extending from a plane of the second plate member.
