The invention relates to a strain relief device (1) for a plug connect for communications and data technology, comprising a base part (10) for holding at least part of the plug connector, and a cable (51) which can be connected to the plug connector, with the base part (10) being designed with first latching means, and closure means (30), with the closure means (30) being designed with second latching means which form a latching connection with the first latching means on the base part (10), wherein the closure means (30) are in the form of a spring comprising two limbs (31) which can be pushed along a guide (20) onto the base part (10), with the base part (10) being designed with at least one support point (21) for the closure means (30), and the closure means (30) being designed such that an opposing force, which is produced by the cable (51) moves the second latching means, which are arranged on the limbs (31), toward the first latching means on the base part (10).
The technical problem is solved by the subject matter having the features of patent claim 1. Further advantageous refinements of the invention can be found in the dependent claims.
The strain relief device 1 has a base part 10, closure means 30 and a head part 40. The base part 10 has two side walls 11, a rear wall 12 and an upper part 13. Guide edges 14 are arranged on the lower face of the side walls 11 and are at right angles to the rear wall 12. Guide edges 15, which run obliquely toward the rear, run on the upper face of the side walls 11 and on the lower face of the upper part 13. In the front region, the upper part 13 has a rounded cutout for holding a cable, which is not shown. On the side facing the rear wall 12, the upper part 13 has an incline 16 which runs inward and upward, and behind which a depression 17 is located. Two guide elements 18 are arranged in the front, side region of the upper part 13. Each guide element 18 firstly forms a guide 19 on the inside, and a guide 20 on the outside. In the region of the guide 20, the side wall 11 is raised somewhat above the upper part 13 in the front region, and forms a first support point 21. Furthermore, in the front region of the guide 20, the guide element 18 has an angle 22, which points downward and forms a second support point. In addition, the side walls 11 have indentations 23 on the insides.
The latching means 30 are essentially in the form of a W-shaped spring with two limbs 31. Angles 32 which point outward are arranged on the free ends of the limbs 31. The limbs 31 are each formed with a latching hook 33 which points inward. In the central region, the W-shaped spring is formed with a concave bulge 34. Four beads 35 are introduced into the spring in the region of the concave bulge 34.
The head part 40 is essentially U-shaped. The free limbs are in this case formed as a smooth guide edge 41 on the outside in the front region, and as an incline 42, which runs outward, on the inside. In the front region, the limb is stepped and is designed to be set-back, thus forming a further guide surface 43. In the rear region, the limbs are formed with ribs 44 on the outside. There is in each case a latching tab 45, which runs obliquely upward toward the rear, centrally on the upper face and lower face of the head part 40. Pyramid-like structures 46 are arranged in the inner, central region of the head part 40. Furthermore, material-saving cutouts 47 are provided in the rear region of the head part 40. The transition from the guide edge 41 to the outside with the ribs 44 forms a stop surface 48. The stop surface 48 is preferably inclined, with the rear wall of the guide element 18 being inclined in a correspondingly complimentary manner. The head part 40 is preferably designed to be completely symmetrical on the upper face and lower face.
