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).
This application is a continuation of U.S. Ser. No. 11/540,431, filed Sep. 29, 2006 which is a continuation of U.S. Pat. No. 7,114,987, issued on Oct. 3, 2006, which is the National Stage of International Application No. PCT/EP02/09023 filed Aug. 12, 2002, which claims priority to German Application No. 101 46 119.4 filed Sep. 19, 2001, and which application(s) is/are incorporated herein by reference.
The strain relief device 1 has a base part 10, closure means 30 and a head part (i.e., latching member) 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 111 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 closure 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. The closure means 30 include a central support element 34 configured to about cable 51, The central support element 34 of the W-shaped spring forms a concave bulge. Four beads 35 are introduced into the spring in the region of the concave bulge 34.
FIG. 3 shows the completely assembled strain relief device. As can be seen, the cable 51 is clamped in the region of the bent-up shield 55 by the concave region 34 of the W-shaped spring and by the structures of the head part 40, with the latching hooks 33 being latched into the ribs 44 on the head part 40. As can also be seen, the guide surface 43 of the head part 40 rests on the upper edge of the guide element 18. The free limbs 31 of the W-shaped spring are supported by the support point 21 and by the angle 22 on the front part of the base part 10.
1. A strain relief device for a telecommunications cable, comprising:
a telecommunications connector for a telecommunications cable, the telecommunications connector including a housing at which the telecommunications cable can be terminated, the housing defining an opening through which the telecommunications cable can extend out from the telecommunications connector;
a base member, the base member including a body defining a hollow interior configured to receive the housing of the telecommunications connector, the base member also defining a groove through which the telecommunications cable can extend;
a latching member, the latching member configured to mount to the base member adjacent the groove, the latching member including first and second limbs extending from a central region, the latching member being substantially rigid; and
a closure member, the closure member configured to mount to the base member adjacent the groove, the closure member including first and second limbs extending from a support element, the support element being configured to cooperate with the central region of the latching member to arrest the telecommunications cable adjacent the groove in the base member, the first and second limbs of the closure member being substantially flexible and being configured to couple to the first and second limbs of the latching member.
2. The strain relief device of claim 1, wherein the latching member is mounted to the base member to enable restricted movement of the latching member along the base member.
3. The strain relief device of claim 1, wherein the first and second limbs of the closure member are configured to apply an inward compression force to the first and second limbs of the latching member in response to a force applied to the support element of the closure member by the telecommunications cable.
4. The strain relief device of claim 1, wherein the closure member is generally W-shaped.
5. The strain relief device of claim 1, wherein the support element of the closure member defines a concave surface.
6. The strain relief device of claim 1, wherein the central region of the latching member defines a concave surface.
7. The strain relief device of claim 1, wherein the concave surface of the latching member defines a plurality of inwardly protruding pyramids.
8. The strain relief device of claim 1, wherein each of the first and second limbs of the latching member defines a plurality of ribs; and wherein each of the first and second limbs of the closure member includes a latching hook for latching to one of the ribs.
9. The strain relief device of claim 8, wherein the latching hooks of the closure member are configured to slide freely along the ribs of the latching member in a first direction.
10. The strain relief device of claim 1, wherein the base member is die-cast.
11. The strain relief device of claim 1, wherein the latching member is die-cast.
12. The strain relief device of claim 1, wherein the base member defines an inwardly inclined surface and an adjacent depression; and wherein the latching member defines an outwardly inclined surface configured to slide along the inwardly inclined surface of the base member and into the depression.
