Abstract

Electrical connector assembly comprising a cover part and a contact assembly for providing a mechanical and electrical contact to an electrode, and connecting arrangements for connecting lead wire to the contact component. The contact component is made of an elongated flat-formed strip forming at least two contact points for the electrode and between the contact points forming a recess having walls enlarging when drawing away from the contact points. The contact points are arranged to press against the electrode for detachable fastening.

Claims

1. Electrical connector assembly comprising a cover part and a contact assembly for providing a mechanical and electrical contact to an electrode, and connecting arrangements for connecting lead wire to the contact component, the contact component being made of an elongated flat-formed strip forming at least two contact points for the electrode and between the contact points forming a recess having walls enlarging when drawing away from the contact points, the contact points being arranged to press against the electrode for detachable fastening.

2. Electrical connector assembly as claimed in claim 1, wherein the flat-formed strip is made of electrically conductive material.

3. Electrical connector assembly as claimed in claim 1, wherein the contact points are arranged to press against the electrode with spring properties of the elongated flat-formed strip.

4. Electrical connector assembly as claimed in claim 1, wherein the recess of the elongated flat-formed strip is formed of two walls placed with a distance to each other, the contact points being formed by the walls.

5. Electrical connector assembly as claimed in claim 4, wherein the walls of the recess are arranged in the two contact points to create contact forces acting in opposite directions and along the longitudinal axis of the flat-formed strip.

6. Electrical connector assembly as claimed in claim 4, wherein bottom part of the recess is arranged to form a third contact point, and the recess is arranged in the third contact point to create a contact force acting in right angle direction with respect to the longitudinal axis of the flat formed strip.

7. Electrical connector assembly as claimed in claim 1, wherein the cover part comprises at least a bottom part and that the elongated flat-formed strip has been fixed to the bottom part.

8. Electrical connector assembly as claimed in claim 7, wherein the cover part further comprises a top cover part attachable to the bottom part.

9. Electrical connector assembly as claimed in claim 6, wherein the cover part is provided with fastening and positioning elements to form a press fit connection with the elongated flat-formed strip, and the elongated flat-formed strip is provided with element co-operating with the fastening and positioning elements in the cover part.

10. Electrical connector assembly as claimed in claim 6, wherein the cover part comprise only a bottom part into which the elongated flat-formed strip has been fixed by moulding.

11. Electrical connector assembly as claimed in claim 1, wherein the elongated flat-formed strip comprises connecting arrangements for connecting lead wire to the connector assembly.

12. Electrical connector assembly as claimed in claim 11, wherein the connecting arrangements for connecting lead wire to the connector assembly is made as an integral part of the elongated flat-formed strip.

13. Electrical connector assembly as claimed in claim 11, wherein the cover part is further provided with lead wire clamp arrangement.

14. Electrical connector assembly as claimed in claim 7, wherein the wire clamp arrangement is provided at least into the bottom part.

15. Electrical connector assembly for connecting lead wire to the press stud of a patient skin electrode, comprising a cover part and a contact component for providing a mechanical and electrical contact to the press stud of the patient skin electrode, and connecting arrangements for connecting lead wire to the contact component, the contact assembly being made of an elongated flat-formed strip forming at least two contact points for the press stud and between the contact points forming a recess having walls enlarging when drawing away from the contact points, the contact points being arranged to press against the press stud for detachable fastening.

16. Electrical connector assembly as claimed in claim 15, wherein the recess of the elongated flat-formed strip is formed of two walls placed with a distance to each other, the contact points being formed by the walls.

17. Electrical connector assembly as claimed in claim 15, wherein bottom part of the recess is arranged to form a third contact point.

18. Electrical connector assembly for connecting lead wire to the press stud of a patient skin electrocardiography electrode, comprising a cover part and a contact component for providing a mechanical and electrical contact to the press stud of the patient skin electrocardiography electrode, and connecting arrangements for connecting lead wire to the contact component, the contact assembly being made of an elongated flat-formed strip forming at least two contact points for the press stud and between the contact points forming a recess having walls enlarging when drawing away from the contact points, the contact points being arranged to press against the press stud for detachable fastening.

19. Electrical connector assembly as claimed in claim 18, wherein the recess of the elongated flat-formed strip is formed of two walls placed with a distance to each other, the contact points being formed by the walls.

20. Electrical snap connector assembly as claimed in claim 18, wherein bottom part of the recess is arranged to form a third contact point.
