Abstract

A connection unit for connecting at least one connection element includes: a housing; a first contact element; a second contact element arranged on an opposite side to the first contact element, at least one receiving space being formed between the first contact element and the second contact element for clamping the at least one connection element between the first contact element and the second contact element; and at least one finger guard element which covers at least some regions of the first contact element and the second contact element in a region of the at least one receiving space. The first contact element, the second contact element, and the finger guard element are borne in the housing in a floating manner.

First claim

The invention claimed is:

1. A connection unit for connecting at least one connection element, comprising:
a housing;
a first contact element;
a second contact element arranged on an opposite side to the first contact element, at least one receiving space being formed between the first contact element and the second contact element for clamping the at least one connection element between the first contact element and the second contact element; and
at least one finger guard element which covers at least some regions of the first contact element and the second contact element in a region of the at least one receiving space,
wherein the first contact element, the second contact element, and the finger guard element are borne in the housing in a floating manner, and
wherein the first contact element and the second contact element are joined together by two spring elements which are arranged at a distance from one another on the two contact elements, a first spring element being attached to a first end region of the two contact elements and a second spring element being fastened to a second end region of the two contact elements, the two spring elements each comprising a U-shape bent wire spring.

2. The connection unit of claim 1 , wherein the at least one finger guard element is movably borne on the first contact element and on the second contact element.

3. The connection unit of claim 1 , wherein the at least one finger guard element has a U shape having a first leg and a second leg formed in parallel with the first leg, the first leg covering the first contact element at least in some regions, and the second leg covering the second contact element at least in some regions.

4. The connection unit of claim 1 , wherein the at least one finger guard element comprises two parts.

5. The connection unit of claim 1 , wherein the first contact element and the second contact element each have a first bearing point and a second bearing point spaced apart from the first bearing point, the first contact element and the second contact element being held on the at least one finger guard element by the first bearing point, and the first contact element and the second contact element being held on the housing by the second bearing point.

6. The connection unit of claim 5 , wherein the first bearing point and the second bearing point of the two contact elements each comprise at least one slot.

7. The connection unit of claim 1 , wherein the at least one finger guard element is borne in the housing in a floating manner by a slotted guide.

8. The connection unit of claim 1 , wherein the first contact element and the second contact element each comprise an oblong metal sheet extending in one plane.

9. The connection unit of claim 1 , wherein the first contact element and the second contact element each have a contact region in the region of the at least one receiving space, which contact regions have a rounded form at least in some portions.

10. A connection arrangement, comprising:
a plurality of the connection unit of claim 1 , arranged in a row.

11. The connection arrangement of claim 10 , further comprising:
a holding frame, the plurality of connection units arranged in the row being held in the holding frame.

12. An electronic device, comprising:
at least one connection unit of claim 1 .

13. An electronic device, comprising:
at least one connection arrangement of claim 10 .

14. A connection unit for connecting at least one connection element, comprising:
a housing;
a first contact element;
a second contact element arranged on an opposite side to the first contact element, at least one receiving space being formed between the first contact element and the second contact element for clamping the at least one connection element between the first contact element and the second contact element; and
at least one finger guard element which covers at least some regions of the first contact element and the second contact element in a region of the at least one receiving space,
wherein the first contact element, the second contact element, and the finger guard element are borne in the housing in a floating manner, and
wherein the first contact element and the second contact element each have a first bearing point and a second bearing point spaced apart from the first bearing point, the first contact element and the second contact element being held on the at least one finger guard element by the first bearing point, and the first contact element and the second contact element being held on the housing by the second bearing point.

15. The connection unit of claim 14 , wherein the first bearing point and the second bearing point of the two contact elements each comprise at least one slot.
