Abstract

An electric shielding contact device in the form of a hollow cylinder that has a contact section and a crimping section. The contact section serves to electrically contact the electric shielding contact device with an electric counter contact. The crimping section serves to attach the electric shielding contact device to an electrical cable upon crimping of the crimping section and has a gaping opening shaped and sized to become a slit when the crimping section of is crimped and the electric shielding contact device attached to the electrical cable.

First claim

What is claimed is:

1. An electric shielding contact device comprising a hollow cylindrical shielding contact having:
a contact section for electrically contacting an electric counter contact; and
a crimping section;
(a) for attaching the hollow cylindrical shielding contact to an electrical cable upon crimping the crimping section, and
(b) having a gaping opening shaped with a plurality of opposing edges forming a spherical triangle with at least one shape being serrated, toothed, and/or jagged and sized to become a slit when the crimping section of the hollow cylindrical shielding contact is crimped and attached to the electrical cable the slit extending in at least one of:
(1) an axial direction of the shielding contact,
(2) partially in an axial direction and partially skewed from the axial direction, and
(3) entirely skewed from an axial direction.

2. The electric shielding contact device according to claim 1 wherein the gaping opening in the crimping section has the form of a spherical triangle defined by:
(a) a starting location inside a material of the shielding contact,
(b) an end location outside the material of the shielding contact, and
(c) a part from only the start location is composed of only two opposing edges.

3. The electric shielding contact device according to claim 1 , wherein a start location in the crimping section further comprises a recess in a material of the shielding contact, the recess having an extension in circumferential direction equal to or smaller than 10-times of a diameter of the slit in the closed state of the crimping section.

4. The electric shielding contact device according to claim 1 , wherein a cross-sectional measurement of at least a rear portion of the crimping section is substantially the same as or greater than a cross-sectional measurement from a mid-portion in the shielding contact towards a rear end of the shielding contact along its axial direction.

5. The electric shielding contact device according to claim 1 , wherein a bottom line of at least a rear portion of the crimping section is tilted at an angle to a bottom line of the contact section, wherein the angle measures less than or substantially equal to 10°.

6. The electric shielding contact device according to claim 1 , further including a middle transitional section between the contact section and the crimping section.

7. The electric shielding contact according to claim 1 , wherein the crimping section has:
(a) in an open state of the crimping section two edges that can be positively joined,
(b) in a closed state of the crimping section two edges of the slit that are positively connected, and
(c) in a positive-locking state of the crimping section two edges that are meshed with one another.

8. The electric shielding contact device according to claim 7 , wherein the opposing edges of the gaping opening in the crimping section in the form of a spherical triangle has at its two inner circumferential length end portions at least one tooth and at least one recess, the at least one tooth and the at least one recess arranged complementary formed to a corresponding tooth of the opposite inner circumferential length end portion of the crimping wall.

9. The electric shielding contact according to claim 1 , wherein the crimping section, when crimped, positively joins the two opposing edges.

10. The electric shielding contact device according to claim 9 , wherein a circumferential direction of the toothed and recessed opposing edges nearer to the mid-portion of the shielding contact are smaller than the circumferential direction of the toothed and recessed opposing edges nearer to the rear end of the shielding contact.

11. The electric shielding contact device according to claim 1 , further comprising an electrical contact means.

12. The electric shielding contact device according to claim 11 , further comprising a preassembled or assembled electrical cable.
