Abstract
A pluggable electrical connection device comprises at least one pin-shaped male element of electrically conductive material and at least one female element. The female element is a metal coil spring having at least four turns sufficiently spaced apart to receive the male element between two mutually adjacent turns. The coil spring may have end portions which are bent to constitute tabs parallel to an axis of said coil spring and soldered to said support. It may also be locked between two elongated holes formed in two opposed sides of a cage and connected to a base circuit fast with said cage by pin.

Pluggable electrical connection device comprising:
- a plurality of pin-shaped male elements of electrically conductive material;
- a plurality of female elements each constituted by a metal coil spring having at least four turns sufficiently spaced apart to receive the male element between two mutually adjacent turns thereof and sufficiently close to be in contact with a respective one of said male elements, said coil springs being mutually identical and having mutually aligned longitudinal axes;
- and
- a strip of insulating material formed with a plurality of separate passages each for receiving one of said coil springs formed at regular intervals.
Pluggable electrical connection device for surface mounting comprising:
- a printed circuit support,
- at least one pin-shaped male element of electrically conductive material;
- at least one female element constituted by a metal coil spring having at least four turns sufficiently spaced apart to receive the male element between two mutually adjacent turns, having end portions which are bent to constitute tabs parallel to an axis of said coil spring and soldered to said support.
Pluggable electrical connection device comprising:
- at least one pin-shaped male element of electrically conductive material;
- at least one female element constituted by a metal coil spring having at least four turns sufficiently spaced apart to receive the male element between two mutually adjacent turns thereof and sufficiently close to be in contact with said male element;
- a base circuit provided with a pair of mutually parallel-walls separated by a distance smaller than a diameter of said coil spring and formed with respective elongated openings for receiving side portions of said coil spring and retaining said coil spring;
- and
- another electrically conductive pin secured to said base circuit, projecting between two successive turns of said coil spring and in contact therewith.
Pluggable electrical connection device comprising:
- at least one pin-shaped male element of electrically conductive material;
- at least one female element constituted by a metal coil spring having at least four turns sufficiently spaced apart to receive the male element between two mutually adjacent turns thereof and sufficiently close to be in contact with said element;
- and an insulating bar on which said plurality of coil springs are threaded at regular intervals, said insulating bar being formed with diametral passages for receiving said male ends.
Pluggable electrical connection device for surface mounting comprising:
- a printed circuit support,
- at least one pin-shaped male element of electrically conductive material;
- and
- at least one female element constituted by a metal coil spring having at least four turns sufficiently spaced apart to receive the male element between two mutually adjacent turns, having end portions which are bent to constitute tabs parallel to an axis of said coil spring and soldered to said support, the two end portions of said female element being disposed symmetrically and the two tabs being in alignment in an axial plane of the coil spring.
