Electrical connector assembly

1. An electrical connector assembly, comprising:

a housing having cavities for receiving electric contact elements and a fastening device to fasten a cable harness that includes the electrical contact elements; and

a cover attached to the housing, wherein a housing transition portion of the housing and a cover transition portion of the cover cooperate with each other to define a tube shaped guiding channel for guiding the cable harness, wherein the fastening device is arranged inside the guiding channel, wherein the fastening device comprises means configured to cooperate with a cable tie such that it guides and holds the cable tie in a holding direction perpendicular to an extension direction of the guiding channel, wherein the fastening device comprises a handle having a first protrusion and a second protrusion spaced apart from the first protrusion by a first distance, protruding from the housing transition portion into the guiding channel and wherein a handle bar connects a free end of the first protrusion and a free end of the second protrusion at a second distance from the housing transition portion, wherein the fastening device has a channel segment including a first rib and a second rib protruding along the holding direction, spaced apart from each other by a third distance from the housing transition portion into the guiding channel, and wherein a rib bar connects a portion of the free end of the first rib and a portion of the free end of the second rib in a fourth distance from the housing transition portion, thereby defining a tube shaped portion.

2. The electrical connector assembly according to claim 1 , wherein the first distance is corresponds to the cable tie such that the first distance is greater than a width of the cable tie and wherein the second distance corresponds to the cable tie such that the second distance is greater than a height of the cable tie.

3. The electrical connector assembly according to claim 1 , wherein the handle bar has a guiding surface located between the first protrusion and the second protrusion, wherein the guiding surface is sloped or curved to enlarge an area of the handle at a location where the cable tie is inserted while assembling.

4. The electrical connector assembly according to claim 1 , wherein the first protrusion and the second protrusion are arranged in a row along the extension direction of the guiding channel.

5. The electrical connector assembly according to claim 1 , wherein the third distance corresponds to the cable tie such that the third distance is greater than a width of the cable tie and wherein the fourth distance corresponds to the cable tie such that the fourth distance is greater than a height of the cable tie.

6. The electrical connector assembly according to claim 1 , wherein the fastening device comprises the handle and the channel segment arranged in a row along the holding direction.

7. The electrical connector assembly according to claim 6 , wherein the first distance is greater than the third distance and the second distance is greater than the fourth distance.

8. The electrical connector assembly according to claim 1 , wherein the guiding channel comprises a channel first end and a channel second end, wherein the channel first end is closer to the cavities than the channel second end, and wherein the fastening device is located at the channel first end.

9. The electrical connector assembly according to claim 8 , wherein the guiding channel comprises holding means for securing a corrugated tube on the channel second end of the guiding channel.

10. The electrical connector assembly according to claim 9 , wherein the holding means comprises a holding rib protruding along the holding direction from the housing transition portion into the guiding channel and wherein the holding rib cooperates with a narrowing in the corrugated tube to secure the corrugated tube.

11. The electrical connector assembly according to claim 1 , wherein the housing is made in one piece.

12. The electrical connector assembly according to claim 1 , wherein the housing is produced by injection molding.

13. An electrical cable harness assembly, comprising;

an electrical connector assembly according to claim 1 ;

the cable harness;

the electrical contact elements; and

the cable tie.
