Electrical Connection Device and Method of Manufacturing the Same
An electrical connection device includes a cable and an electrical plug device. The electrical plug device has a crimping element with a crimping sleeve crimped on the cable. A pair of legs of the crimping sleeve that are bent toward one another to enclose the cable are welded together.
1 . An electrical connection device, comprising:
a cable; and
an electrical plug device having a crimping element with a crimping sleeve crimped on the cable, a pair of legs of the crimping sleeve that are bent toward one another to enclose the cable are welded together.
2 . The electrical connection device of claim 1 , further comprising a support sleeve disposed under the crimping sleeve.
3 . The electrical connection device of claim 1 , wherein the legs of the crimping sleeve have a pair of interlocking end contours.
4 . The electrical connection device of claim 3 , wherein the legs are welded in an engagement region of the interlocking end contours.
5 . An electrical connection device, comprising:
a cable having a shielding;
an electrical plug device having a crimping element electrically contacting the shielding, the crimping element has a crimping sleeve; and
a support sleeve disposed between the shielding and an exposed end region of the shielding, the crimping sleeve is positioned around an outer circumference of the cable and encloses the exposed end region, the crimping sleeve is welded to the support sleeve.
6 . A wiring harness, comprising:
an electrical connection device including a cable and an electrical plug device having a crimping element with a crimping sleeve crimped on the cable, a pair of legs of the crimping sleeve that are bent toward one another to enclose the cable are welded together.
7 . A method of manufacturing an electrical connection device, comprising:
providing a cable and an electrical plug device, the electrical plug device has a housing, a plug contact element, and a crimping element with a crimping sleeve;
connecting the crimping element to the cable by crimping a pair of legs of the crimping sleeve around the cable; and
welding the legs of the crimping sleeve to one another.
8 . The method of claim 7 , wherein the welding is performed with a laser.
9 . The method of claim 8 , further comprising connecting a support sleeve to the cable by crimping.
10 . The method of claim 9 , wherein the legs of the crimping sleeve are welded together at a level of the support sleeve.
11 . The method of claim 10 , further comprising a cable having a conductor and an inner sheath surrounding the conductor.
12 . The method of claim 11 , wherein the inner sheath is surrounded by a shielding, which is surrounded by a cable sheath.
13 . The method of claim 12 , wherein a section of the cable sheath is removed, a shielding braid of the shielding is cut to length, a section of the inner sheath is removed, and the crimping element is connected to the cable while enclosing the shielding.
14 . The method of claim 13 , wherein the legs of the crimping sleeve abut against an outer circumference of the shielding.
15 . The method of claim 13 , wherein the crimping sleeve is welded to an end region of the shielding that is exposed after the cable sheath has been cut.
16 . The method of claim 13 , wherein the crimping sleeve is welded to the support sleeve.
17 . The method of claim 13 , wherein, after the shielding braid has been cut, a film disposed between the shielding braid and the inner sheath is cut off.
18 . The method of claim 13 , wherein, after the inner sheath has been cut, the plug contact element is connected to the conductor and arranged in a contact element chamber of the housing.
