Abstract

An electric connection device for connecting a conductor having at least one contact bush of a conductive material with a clearing for a contact spring and a contact spring disposed thereat which clamps a conductor plugged into the contact bush from a plug-in side against the inner wall of the contact bush wherein the contact spring is pivotable outwardly through the clearing.

Claims

1. An electric connection device for connecting a conductor having at least one contact bush of a conductive material with a clearing for a contact spring and a contact spring disposed thereat which clamps a conductor plugged into the contact bush from a plug-in side against an inner wall of the contact bush wherein the contact spring is pivotable outwardly through the clearing;

wherein the contact spring is made of a conductive material and/or non-conductive material at least in part;

further including a releasing device for releasing the clamp of the contact spring; and

wherein the releasing device abuts the contact bush and is surrounded by the contact bush and the contact spring.

2. The electric connection device according to claim 1, wherein the contact bush is rotationally symmetric in cross-section at least in one place and is in particular manufactured from a turned component.

3. The electric connection device according to claim 1, wherein a linear arrangement of conductor to be connected and connected contact element is present.

4. The electric connection device according to claim 1, wherein the contact bush comprises a central receiving opening for receiving a conductor wherein the diameter of the receiving opening is matched to a cross-section of the conductor to be received.

5. The electric connection device according to claim 1 wherein the contact bush is configured slotted at one end opposite the plug-in side to facilitate placement onto a contact pin.

6. The electric connection device according to claim 1 wherein the attachment portion of the contact spring is received in a groove of the contact bush.

7. The electric connection device according to claim 1, wherein a conical insertion ring is provided at the releasing device.

8. The electric connection device according to claim 1, wherein at least one engagement element is provided at the releasing device.

9. The electric connection device according to claim 1, wherein the releasing device is semicircular in cross-section to bear against the contact bush.

10. The electric connection device according to claim 1, wherein multiple cylindrical contact bushes are disposed adjacent to receive one conductor each.

11. The electric connection device according to claim 1 wherein four cylindrical contact bushes are disposed at the corners of a rectangle and one contact bush, centrally in the rectangle, wherein a diagonal diameter through three contact bushes is smaller than four times the smallest diameter of one single contact bush.

12. The electric connection device according to claim 1 wherein the contact spring comprises a straight clamping edge and/or wherein the clamping groove is configured at a transverse opening and in particular at a transverse bore or transverse groove.

15. The electric connection device of claim 1 further including one receiving opening for a conductor to be plugged in, and a clamping groove is configured at the contact bush transverse to the plug-in direction of the conductor.

13. An electric connection device for connecting a conductor, comprising:

at least one contact bush of a conductive material with a clearing for a contact spring and a contact spring which clamps a conductor plugged into the contact bush from a plug-in side against a wall of the contact bush, wherein the contact spring is pivotable outwardly through the clearing, the contact spring is a separate component surrounding the contact bush at least in part by an attachment portion and includes a spring portion for clamping the conductor to be connected against the wall of the contact bush, and the contact bush includes a transverse opening transverse to the longitudinal extension of a receiving opening in a clamping zone.

14. The electric connection device of claim 13 further including a clamping edge is located on the contact spring for clamping the conductor to be plugged in.

16. The electric connection device of claim 13 further including one receiving opening for a conductor to be plugged in, and a clamping groove is configured at the contact bush transverse to the plug-in direction of the conductor.
