Abstract

A high-current plug-in connector for transmitting electrical currents, having a housing made of electrically conducting material, designed to mechanically and electrically connect to a cable, the housing having at least one open side for inserting a mating plug-in connector made of an electrically conducting material, and forming a chamber for accommodating the mating plug-in connector, and at least one contact element, which is arranged on the housing and designed so that the contact element establishes an electrical contact having a contact area and a contact pressure between the housing and the mating plug-in connector inserted into the housing, wherein the contact element is designed as a coil spring.

Claims

1. A high-current insertion-connected connector for transmitting electrical currents, comprising:

a housing including electrically conductive material, said housing designed to be connected mechanically and electrically to a cable, and having at least one open side or end, and forming a chamber for receiving a mating insertion-connected connector;

said mating insertion-connected connector for insertion within said housing, made of an electrically conductive material;

at least one contact member arranged against the housing to make an electrical contact, at which there is an area of contact and a contact-making pressure, between the housing and the mating insertion-connected connector inserted into the housing, the at least one contact member including a coil spring, there being arranged in the housing, in the chamber to receive the mating insertion-connected connector; and

a mounting member made of an electrically insulating material to hold the at least one contact member in a predetermined position, said mounting member receiving the mating insertion-connected connector, and including, for each of said at least one contact member in the form of a coil spring, a spigot having a free end, on each of which spigots the coil spring is so arranged that the spigot engages axially in turns of the coil spring.

2. The high-current insertion-connected connector of claim 1, wherein the mating insertion-connected connector includes a blade-type insertion-connected connector, an insertable blade, or a contact-making blade.

3. The high-current insertion-connected connector claim 1, wherein a central longitudinal axis of the coil spring is aligned parallel to a straight line.

4. The high-current insertion-connected connector of claim 3, including two, three, four, or more coil springs, with central longitudinal axes of each of said coil springs being aligned parallel to one another.

5. The high-current insertion-connected connector of claim 1, wherein that the at least one contact member in the form of said coil spring makes electrical and mechanical contact with the housing and the mating insertion-connected connector at radially outer sides of turns of the coil spring.

6. The high-current insertion-connected connector claim 1, wherein a longitudinal center axis of at least one turn of the coil spring is tilted relative to a longitudinal center axis of the coil spring by a predetermined angle greater than zero.

7. The high-current insertion-connected connector of claim 1, including the mounting member is formed in two parts.

8. The high-current insertion-connected connector of claim 1, wherein the mounting member includes apertures, with the at least one contact member in the form of a coil spring making electrical and mechanical contact with the housing by fitting through an aperture and projecting into the chamber within the housing for the mating insertion-connected connector.

9. The high-current insertion-connected connector of claim 1, wherein the mounting member includes two flaps facing one another, resiliently deflectable, said flaps having a spacing therebetween smaller than the thickness of the mating insertion-connected connector.

10. The high-current insertion-connected connector of claim 1, wherein a radial diameter of the at least one contact member in the form of said coil spring is perpendicular to a central longitudinal axis of the coil spring and greater than a distance between the housing and a mating insertion-connected connector inserted in the housing.

11. The high-current insertion-connected connector of claim 2, wherein a central longitudinal axis of the coil spring is aligned parallel to a straight line.

12. The high-current insertion-connected connector of claim 11, including two, three, four or more coil springs, with central longitudinal axes of each of said coil springs being aligned parallel to one another.

13. The high-current insertion-connected connector according to claim 3, wherein that the at least one contact member in the form of said coil spring makes electrical and mechanical contact with the housing and the mating insertion-connected connector at radially outer sides of turns of the coil spring.

14. The high-current insertion-connected connector of claim 3, wherein a longitudinal center axis of at least one turn of the coil spring is tilted relative to a longitudinal center axis of the coil spring by a predetermined angle greater than zero.

15. The high-current insertion-connected connector of claim 5, wherein a longitudinal center axis of at least one turn of the coil spring is tilted relative to a longitudinal center axis of the coil spring by a predetermined angle greater than zero.

16. The high-current insertion-connected connector of claim 7, wherein the mounting member includes apertures, with the at least one contact member in the form of a coil spring making electrical and mechanical contact with the housing by fitting through an aperture and projecting into the chamber within the housing for the mating insertion-connected connector.

17. The high-current insertion-connected connector of claim 8, wherein the mounting member includes two flaps facing one another, resiliently deflectable, said flaps having a spacing therebetween smaller than the thickness of the mating insertion-connected connector.

18. The high-current insertion-connected connector of claim 16, wherein the mounting member includes two flaps facing one another, resiliently deflectable, said flaps having a spacing therebetween smaller than the thickness of the mating insertion-connected connector.
