Cable for transmitting signals
A cable for the transmission of signals, includes a plurality of leads, on whose inner conductors an electrically conductive end piece is affixed. At least one of the end pieces includes a first latching element. The cable includes a coupler element, and the coupler element has a body having a longitudinal axis. In addition, the body has parallel feed-throughs, electrically insulated from each other, to accommodate the end pieces. At least one of the feed-throughs includes a second latching element. The end piece is inserted into the feed-through such that the first latching element locks into place with the second latching element. The body furthermore has a first surface and a second surface to guide a mating piece of the coupler element, the first surface having a radially outwardly directed normal vector, and the second surface having a radially inwardly directed normal vector.
1. A cable for transmitting signals, comprising:
a plurality of leads;
an electrically conductive end piece fixedly provided on an internal conductor of each lead, at least one end piece including a first latch;
a coupler having a body formed of one piece from an insulating material and having a longitudinal axis;
wherein the body includes parallel feed-throughs, electrically isolated from each other, that accommodate the end pieces, at least one feed-through including a second latch arranged as an integral component of the body;
wherein the end piece is inserted into the feed-through such that the first latch cooperates with the second latch to lock the end piece and the body; and
wherein the body includes a first surface and a second surface arranged as a guide for a mating piece of the coupler, the first surface having a radially outwardly directed normal vector and the second surface having a radially inwardly directed normal vector; and
wherein a lead is axially secured in form-locking manner by a secondary latching element that engages at the end piece by a shift of the secondary latching element in a tangential and orthogonal direction to the longitudinal axis without intersecting it.
2. The cable according to claim 1 , wherein the cable is arranged without a shield.
3. The cable according to claim 1 , wherein points along a circumferential line on the first surface and/or on the second surface have different distances from the longitudinal axis, for mechanical coding.
4. The cable according to claim 1 , wherein the first surface is axially set back in relation to the longitudinal axis, in comparison with the second surface.
5. The cable according to claim 1 , wherein in cross-section, the first surfaces and the second surface are located radially opposite each other and are separated by an air gap.
6. The cable according to claim 1 , wherein the feed-throughs completely surround the end pieces along a circumferential line on the end piece, at least in a subsection extending along a direction of the longitudinal axis.
7. The cable according to claim 1 , wherein at least one of the end pieces is connected to an internal conductor of a lead, via a plastically, crimpedly deformed connection element.
8. The cable according to claim 1 , further comprising a secondary latch captively accommodated by the body.
9. The cable according to claim 1 , wherein the cable includes a first pair of leads twisted together, and a second pair of leads twisted together.
