Abstract

Embodiments disclose a contact part comprising a sleeve forming a receiving space for inserting a plug-in contact in an insertion direction, at least one contact spring secured to the inside of the sleeve, and a locking pin configured to be displaceably guided in the sleeve between first and second end positions in sliding contact with the contact spring, wherein the locking pin is configured to push the contact spring in the direction of the receiving space to varying degrees depending on the position of the locking pin between the two end positions. Embodiments disclose a method for producing a contact part comprising providing a sheet metal part and at least one contact spring held in a form-locked manner in the sheet metal part, and forming the sheet metal part to obtain a sleeve that forms a receiving space for inserting a plug-in contact in the insertion direction.

First claim

What is claimed is:

1. A contact part, comprising:
a sleeve enclosing a receiving space;
a contact spring secured to an inside of the sleeve, the contact spring including one or more planar terminal bearing regions configured to mount the contact spring in the sleeve, each of the one or more planar terminal bearing regions having a central recess; and
a locking pin configured to:
be displaceably guided in the sleeve between a first end position and a second end position,
be in sliding contact with the contact spring, and
push the contact spring towards the receiving space to a degree depending on a position of the locking pin between the first and second end positions.

2. The contact part according to claim 1 , wherein the sleeve is a formed sheet metal part configured to hold the contact spring in at least a form-locked or form-fit manner.

3. The contact part according to claim 1 , wherein the contact spring is made of steel or includes steel.

4. The contact part according to claim 1 , wherein the contact spring includes a first bent section and a second bent section bent towards the receiving space.

5. The contact part according to claim 4 , wherein:
the first bent section corresponds to the first end position, and
the locking pin exerts a lower force on the contact spring in the first end position than in the second end position.

6. The contact part according to claim 5 , wherein the second end position is arranged between the first and second bent sections.

7. The contact part according to claim 4 , wherein the second bent section is bent further into a lower portion of the receiving space than the first bent section.

8. The contact part according to claim 1 , further comprising:
a plate-shaped contact tab held in the sleeve in at least a form-locked manner,
wherein the receiving space is located between the contact tab and the contact spring.

9. The contact part according to claim 8 , wherein the contact tab has a projecting profile on a surface of the contact tab.

10. The contact part according to claim 9 , wherein the contact tab is made of copper, and the projecting profile is silver-coated.

11. The contact part according to claim 8 , wherein the sleeve includes one or more receiving holes configured to cooperate with one or more protrusions in the plate-shaped contact tab.

12. The contact part according to claim 1 , wherein the sleeve includes a plurality of side edges configured to mutually engage with each other in a form-locked manner.

13. A method for producing a contact part, comprising:
providing a sheet metal part and a contact spring, wherein the sheet metal part includes a tab and the contact spring includes a planar terminal bearing region having a central recess;
bending the tab to hold the contact spring against the sheet metal part in at least one of a form-locked manner or a force-fit manner, the tab engaging the central recess; and
bending the sheet metal part to form a sleeve that encloses a receiving space, wherein the contact spring is secured inside the sleeve.

14. The method according to claim 13 , wherein:
the sheet metal part further includes one or more butt edges, and
bending the sheet metal part to form the sleeve includes engaging the one or more butt edges with each other in a form-locked manner.

15. The method according to claim 13 , wherein bending the sheet metal part to form the sleeve further includes engaging a contact tab with the sheet metal part in at least a form-locked manner.

16. A high-current connection system for a vehicle, comprising:
a sleeve enclosing a receiving space for inserting a plug-in contact;
a contact spring secured to an inside of the sleeve;
a plate-shaped contact tab held in the sleeve in at least a form-locked manner, the receiving space being located between the contact tab and the contact spring; and
a locking pin configured to:
be displaceably guided in the sleeve between a first end position and a second end position,
be in sliding contact with the contact spring, and
push the contact spring towards the receiving space to a degree depending on a position of the locking pin between the first and second end positions.

17. The system according to claim 16 , wherein the sleeve is a formed sheet metal part configured to hold the contact spring in at least a form-locked or form-fit manner.

18. The system according to claim 16 , wherein:
the contact spring includes a first bent section and a second bent section bent towards the receiving space;
the first bent section corresponds to the first end position, and
the locking pin exerts a lower force on the contact spring in the first end position than in the second end position.

19. The system according to claim 18 , wherein the second end position is arranged between the first and second bent sections.

20. The system according to claim 16 , wherein the contact spring comprises one or more planar terminal bearing regions configured to mount the contact spring in the sleeve, each of the one or more planar terminal bearing regions having a central recess.
