Abstract

A plug connector part for connecting to a mating plug connector part includes: a housing part on which a plug-in section for a plug-in connection to the mating plug-in connector part is arranged; at least one contact element arranged on the plug-in section so as to make electrical contact with an associated mating contact element of the mating connector part; an electrical line arranged on the housing part and electrically connected to the at least one contact element; a strain relief element movably arranged on the housing part; and an adjusting element that can be brought into operative connection with the strain relief element. Via actuation of the adjusting element, the strain relief element is movable into a position in which the strain relief element fixes the electrical line, relative to the housing part, in a tension-loadable manner.

Claims

1. A plug connector part for connecting to a mating plug connector part, the plug connector part comprising:

a housing part on which a plug-in section for a plug-in connection to the mating plug connector part is arranged;

at least one contact element arranged on the plug-in section so as to make electrical contact with an associated mating contact element of the mating plug connector part;

an electrical line arranged on the housing part and electrically connected to the at least one contact element;

a strain relief element movably arranged on the housing part; and

an adjusting element configured to be brought into operative connection with the strain relief element,

wherein, via actuation of the adjusting element, the strain relief element is movable into a position in which the strain relief element fixes the electrical line, relative to the housing part, in a tension-loadable manner, and

wherein a body of the strain relief element has a wedge shape along a longitudinal direction of the strain relief element.

2. The plug connector part according to claim 1, wherein the adjusting element is actuatable by a tool from outside of the housing part.

3. The plug connector part according to claim 1, wherein the adjusting element comprises a screw which is configured to be brought into threaded engagement with the strain relief element and to be rotated in order to move the strain relief element, relative to the housing part.

4. The plug connector part according to claim 1, wherein the strain relief element has a threaded element with which the adjusting element, for moving the strain relief element, is configured to be brought into threaded engagement.

5. The plug connector part according to claim 4, wherein the threaded element comprises a nut arranged in a rotationally-fixed manner in an insertion opening of the strain relief element.

6. The plug connector part according to claim 1, wherein the strain relief element is guided on a guide device of the housing part so as to be displaceable.

7. The plug connector part according to claim 6, wherein the guide device is configured to guide the strain relief element longitudinally along a clamping direction at the housing part.

8. The plug connector part according to claim 7, wherein the clamping direction is directed in parallel to a longitudinal direction along which the electrical line is to be introduced into the housing part.

9. The plug connector part according to claim 1, wherein the strain relief element has a clamping surface which, for jamming, is configured to be brought into contact with the electrical line.

10. The plug connector part according to claim 9, wherein, at the clamping surface, at least one of the contour elements projecting from the clamping surface is configured to fix the electrical line to the housing part in a tension-loadable manner.

11. The plug connector part according to claim 1, wherein at least one toothed section is formed at the housing part, which toothed section is in contact with the electrical line when the electrical line is arranged at the housing part.

12. The plug connector part according to claim 11, wherein the toothed section is formed at an edge of an opening through which the electrical line extends into the housing part.

13. A method for producing a connector part for connecting to a mating plug connector part, the method comprising:

arranging a strain relief element movably on a housing part;

arranging an electrical line on the housing part, the electrical line being connectable to at least one contact element to make electrical contact with an associated mating contact element of the mating plug connector part;

bringing an adjusting element into operative connection with the strain relief element; and

actuating the adjusting element in order to move the strain relief element into a position in which the strain relief element fixes the electrical line, relative to the housing part, in a tension-loadable manner,

wherein a body of the strain relief element has a wedge shape along a longitudinal direction of the strain relief element.

14. The method according to claim 13, wherein the strain relief element is guided on a guide device of the housing part so as to be displaceable, and is moved along the guide device via actuation of the adjusting element.
