Abstract

A contact for an electrical plug connector comprises a plug portion and a contact spring. The plug portion has an opening receiving a pin contact in an insertion direction. The contact spring is connected by at least one spring arm base to the plug portion and extends from the at least one spring arm base toward the opening in a direction opposite the insertion direction. The contact spring exerts a contact force on the pin contact perpendicular to the insertion direction.

First claim

What is claimed is:

1. A contact for an electrical plug connector, comprising:
a plug portion having an opening receiving a pin contact in an insertion direction and a counter-clamping region; and
a contact spring having at least two spring arms which jointly support a free end of the contact spring, a clamping region positioned opposite the counter clamping region and laterally offset relative to the counter-clamping region prior to pin contact insertion, and being connected by at least one spring arm base to the plug portion and extending from the at least one spring arm base toward the opening in a direction opposite the insertion direction, the contact spring exerting a contact force on the pin contact perpendicular to the insertion direction.

2. The contact of claim 1 , wherein the contact spring is at least partially L-shaped in the insertion direction.

3. The contact of claim 1 , wherein a first spring arm of the at least two spring arms is connected to a side wall of the plug portion and a second spring arm of the at least two spring arms is connected to a ceiling of the plug portion.

4. The contact of claim 1 , further comprising an overbending protection device extending transverse to the insertion direction, the overbending protection device preventing deflection of the contact spring beyond a maximum elastic deflection.

5. The contact of claim 1 , wherein the plug portion has an insertion ramp formed in a region of the opening, spaced apart from a front edge of the contact spring, and extending obliquely relative to the insertion direction.

6. The contact of claim 5 , wherein the insertion ramp extends toward a chamfer formed on a front edge of the contact spring.

7. The contact of claim 6 , wherein a ramp insertion angle between the insertion ramp and a longitudinal axis of the contact is smaller than a chamfer insertion angle between the chamfer and the longitudinal axis.

8. The contact of claim 1 , further comprising an insulation crimp portion having a recess fixing an insulation of an electric conductor to the contact.

9. The contact of claim 8 , wherein the recess is an insulation crimp recess disposed in an insulation crimp flank of the insulation crimp portion.

10. The contact of claim 9 , wherein the insulation crimp recess is a through-opening extending through the insulation crimp flank.

11. The contact of claim 8 , wherein the recess is a base recess formed in a base of the contact.

12. The contact of claim 11 , wherein the base recess extends from the insulation crimp portion at least into a transition crimp portion, the transition crimp portion connecting the insulation crimp portion to a conductor crimp portion of the contact.

13. A carrier assembly for equipping electrical plug connectors with contacts, comprising:
a contact including; a plug portion having an opening receiving a pin contact in an insertion direction and a laterally offset counter-clamping region; and a contact spring having at least two spring arms which jointly support a free end of the contact spring, a clamping region positioned opposite the counter-clamping region, and being connected by at least one spring arm base to the plug portion, the contact spring extending from the at least one spring arm base toward the opening in a direction opposite the insertion direction and exerting a contact force on the pin contact perpendicular to the insertion direction, and
a carrier strip fastened to the contact.

14. The carrier assembly of claim 13 , wherein the carrier strip includes a transport hole having a drive edge extending transversely to a longitudinal axis of the carrier strip, a transport pin engaging the drive edge to drive the carrier strip.

15. The carrier assembly of claim 13 , wherein the carrier strip includes an impression having a rounded region.

16. A contact for an electrical plug connector, comprising:
a plug portion having an opening receiving a pin contact in an insertion direction, a counter-clamping region, and an insertion ramp formed in a region of the opening and extending obliquely relative to the insertion direction; and
a contact spring having a clamping region positioned opposite the counter clamping region laterally offset relative to the counter-clamping region prior to pin contact insertion and being connected by at least one spring arm base to the plug portion and extending from the at least one spring arm base toward the opening in a direction opposite the insertion direction, the contact spring exerting a contact force on the pin contact perpendicular to the insertion direction, the insertion ramp is spaced apart from a front edge of the contact spring and extends toward a chamfer formed on the front edge of the contact spring.

17. The contact of claim 16 , wherein a ramp insertion angle between the insertion ramp and a longitudinal axis of the contact is smaller than a chamfer insertion angle between the chamfer and the longitudinal axis.
