Abstract

The crimping element for holding a wire with a nominal diameter of approximately 0.1 mm or less comprises sheet-metal with a base portion extending in a base plane and a holding portion connected to the base portion. The holding portion comprises first and second clamping elements spaced apart from each other by a holding portion recess. The first element comprises a first clamping portion extending in a first plane and connected to the base portion and a second clamping portion, forming a first clamping region for holding the wire. The second element comprises a third clamping portion extending in a second plane and connected to the base portion and a fourth clamping portion, forming a second clamping region for holding the wire The first plane forms a first angle approximately 0°-10° with the base portion plane. The second plane forms a second angle approximately 1°-10° with the first plane.

First claim

The invention claimed is:

1. A crimping element for holding a wire with a nominal diameter of approximately 0.1 mm or less, comprising:
a sheet-metal element comprising a base portion extending in a base plane and a holding portion connected to the base portion, wherein the holding portion comprises a first clamping element and a second clamping element, which is spaced apart from the first clamping element by means of a recess in the holding portion,
wherein the first clamping element comprises a first clamping portion connected to the base portion, and a second clamping portion connected to the first clamping portion, and the first clamping portion and the second clamping portion are bent toward one another about a first bending axis to form a first clamping region configured to hold the wire between the first clamping portion and the second clamping portion,
wherein the second clamping element comprises a third clamping portion, which is connected to the base portion, and a fourth clamping portion, which is connected to the third clamping portion, and the third clamping portion and the fourth clamping portion are bent toward one another about a second bending axis to form a second clamping region configured to hold the wire between the third clamping portion and the fourth clamping portion,
wherein the first clamping portion of the first clamping element extends in a first plane, which forms a first angle in a range of approximately 0° to 10° with the base plane of the base portion, and
wherein the third clamping portion of the second clamping element extends in a second plane, which forms a second angle in a range of approximately 1° to 10° with the first plane.

2. The crimping element as claimed in claim 1 , wherein the second angle is in a range of approximately 2° to 3°.

3. The crimping element as claimed in claim 1 , wherein the first angle is approximately 0°.

4. The crimping element as claimed in claim 1 , wherein the first bending axis extends substantially perpendicularly with respect to a direction of longitudinal extent of the recess.

5. The crimping element as claimed in claim 4 , wherein the second bending axis extends substantially parallel to the first bending axis.

6. The crimping element as claimed in claim 1 , wherein the holding portion comprises a third clamping element, which is spaced apart from the second clamping element by a further recess in the holding portion,
wherein the third clamping element comprises a fifth clamping portion, which is connected to the base portion, and a sixth clamping portion, which is connected to the fifth clamping portion, and the fifth clamping portion and the sixth clamping portion form a third clamping region configured to hold the wire between the fifth clamping portion and the sixth clamping portion,
wherein the fifth clamping portion of the third clamping element extends in a third plane, which substantially coincides with the first plane of the first clamping element.

7. The crimping element as claimed in claim 1 , wherein the base portion also comprises contact elements, which are configured to make electrical and mechanical contact with an electrical printed circuit board.

8. The crimping element as claimed in claim 2 , wherein the second clamping portion and the first clamping portion are bent toward one another about a first bending axis and the first bending axis extends substantially perpendicularly with respect to a direction of longitudinal extent of the recess.

9. The crimping element as claimed in claim 2 , wherein the first angle is approximately 0°.

10. The crimping element as claimed in claim 9 , wherein the base portion also comprises contact elements, which are configured to make electrical and mechanical contact with an electrical printed circuit board.

11. The crimping element as claimed in claim 3 , wherein the second clamping portion and the first clamping portion are bent toward one another about a first bending axis and the first bending axis extends substantially perpendicularly with respect to a direction of longitudinal extent of the recess.

12. The crimping element as claimed in claim 11 , wherein the base portion also comprises contact elements, which are configured to make electrical and mechanical contact with an electrical printed circuit board.

13. The crimping element as claimed in claim 4 , wherein the base portion also comprises contact elements, which are configured to make electrical and mechanical contact with an electrical printed circuit board.

14. The crimping element as claimed in claim 5 , wherein the base portion also comprises contact elements, which are configured to make electrical and mechanical contact with an electrical printed circuit board.

15. The crimping element as claimed in claim 6 , wherein the base portion also comprises contact elements, which are configured to make electrical and mechanical contact with an electrical printed circuit board.

16. A crimping system, comprising:
a wire with a nominal diameter of approximately 0.1 mm or less,
a crimping element for holding the wire, comprising:
a sheet-metal element comprising a base portion extending in a base plane and a holding portion connected to the base portion, wherein the holding portion comprises a first clamping element and a second clamping element, which is spaced apart from the first clamping element by means of a recess in the holding portion,
wherein the first clamping element comprises a first clamping portion connected to the base portion, and a second clamping portion connected to the first clamping portion, and the first clamping portion and the second clamping portion are bent toward one another about a first bending axis to form a first clamping region configured to hold the wire between the first clamping portion and the second clamping portion,
wherein the second clamping element comprises a third clamping portion, which is connected to the base portion, and a fourth clamping portion, which is connected to the third clamping portion, and the third clamping portion and the fourth clamping portion are bent toward one another about a second bending axis to form a second clamping region configured to hold the wire between the third clamping portion and the fourth clamping portion,
wherein the first clamping portion of the first clamping element extends in a first plane, which forms a first angle in a range of approximately 0° to 10° with the base plane of the base portion, and
wherein the third clamping portion of the second clamping element extends in a second plane, which forms a second angle in a range of approximately 1° to 10° with the first plane;
