[0002] In the fields of cables and optical fibers, an SR tail card (Stress Relief End Cap) generally refers to a device used to protect and manage the end of a cable. Its main functions are to provide stress relief, prevent the end of the cable from being damaged due to mechanical stress, protect the end of the cable from the external environment, and ensure the stability and reliability of the connection.

[0003] As shown in the attached drawing of the patent document "CN111431012A" for "A Method for Producing SR Cables and SR Cables", it includes a cable body 1 and an SR joint 2. The SR joint 2 is sleeved outside the cable body 1, and the SR joint 2 is integrally formed with the cable body 1. Figure 2 In this patent, the cable is fixed by passing through the SR joint. Since the cable needs to be pulled in multiple directions during use, the SR joint is simultaneously subjected to external forces in multiple directions, which may cause the risk that the SR joint spreads open or detaches from the cable.

[0004] Content of the Utility Model

[0005] The purpose of the utility model is to provide an enhanced structure of an SR tail card to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An enhanced structure of an SR tail card includes an SR tail card body and a bottom shell. A circumferential clamping groove is formed on the SR tail card body. The bottom shell is provided with an outlet hole and a protrusion. The protrusion limits the area of the outlet hole. One end of the SR tail card body close to the clamping groove passes through the outlet hole, and the SR tail card body is tightly fitted with the bottom shell.

[0008] It further includes a face shell. The face shell is provided with an insertion interface, and the insertion interface can be inserted into the clamping groove. The upper surface of the face shell abuts against the lower surface of the bottom shell, and the face shell, the bottom shell and the clamping groove are clamped.

[0009] As a further technical solution, the bottom shell is provided with a groove, the face shell is provided with a protrusion, the protrusion is provided with an insertion portion, the groove is clamped with the protrusion, and the insertion portion is inserted into the groove and abuts against the bottom of the groove.

[0010] Further technical solution: A plurality of receiving grooves are formed in the pore wall of the wire outlet hole of the bottom case, and the contact portion between the SR tail card body and the pore wall of the wire outlet hole is in press fit with the receiving grooves.

[0011] Further technical solution: The upper aperture diameter of the wire outlet hole is larger than the lower aperture diameter of the wire outlet hole.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Please refer to Figures 1-4 ;

[0024] An enhanced structure for an SR tail card, comprising an SR tail card body 1 and a bottom shell 2. In this embodiment, the bottom shell 2 is made of an elastic material. A circumferential clamping groove 3 is provided on the SR tail card body 1, and the clamping groove 3 is an annular clamping groove 3. The bottom shell 2 includes a flat plate portion 21 and an inclined portion 22. One end of the flat plate portion 21 and the inclined portion 22 are fixedly connected or integrally formed. An outlet hole 4 is provided on the flat plate portion 21 of the bottom shell 2. A raised portion 5 surrounding the outlet hole 4 is also fixedly provided on the lower surface of the flat plate portion 21 of the bottom shell 2. It should be noted that in this embodiment, the raised portion 5 limits the outlet area of the outlet hole 4. Let one end of the SR tail card body 1 close to the clamping groove 3 be the tail portion 6, and the tail portion 6 can pass through the outlet hole 4. In some embodiments, since the SR tail card body 1 is made of an elastic material, the tail portion 6 can pass through the outlet hole 4 by extrusion. In this embodiment, preferably, one end of the tail portion 6 is a flat surface 7, thereby reducing the area of the tail portion 6 so that the tail portion 6 can smoothly pass through the outlet hole 4, enabling the SR tail card body 1 and the bottom shell 2 to be tightly fitted. In this embodiment, preferably, the SR tail card body 1 and the bottom shell 2 are in an interference fit manner, that is, one end of the SR tail card body 1 close to the clamping groove 3 and facing away from the bottom shell 2 abuts against the hole wall of the outlet hole 4 on the bottom shell 2, and then a negative clearance is formed between the outer wall of the SR tail card body 1 and the hole wall of the outlet hole 4 through the extrusion deformation of the SR tail card body 1 and the bottom shell 2. The enhanced structure of the SR tail card further includes a face shell 8. The face shell 8 includes a plug-in portion 81 and a fixing portion 82. The plug-in portion 81 and the fixing portion 82 are integrally formed. The plug-in portion 81 includes two support plates 9 and a plug-in plate 10. The two support plates 9 are respectively located on both sides of the plug-in plate 10 and are integrally formed with the plug-in plate 10. When the plug-in plate 10 is horizontally placed, the plug-in plate 10 is located at the middle position of the height of the support plates 9. An insertion opening 11 is provided on the plug-in plate 10 of the face shell 8, and the shape of the insertion opening 11 is adapted to that of the clamping groove 3, so that the insertion opening 11 can be inserted into the clamping groove 3. It should be noted that when the insertion opening 11 is inserted into the clamping groove 3, the upper surface of the support plate 9 abuts against the lower surface of the flat plate portion 21 of the bottom shell 2, and a gap 12 is left between the plug-in plate 10 and the lower surface of the flat plate portion 21 of the bottom shell 2 to accommodate the raised portion 5.

[0025] Specifically, under normal circumstances, the operator passes the cable through the SR tail clamp body 1 to complete the fixation of the cable by the SR tail clamp body 1. Since the user needs to move the position of the cable and then bend and fix the cable when using the cable, the stress borne by the SR tail clamp body 1 is relatively large. Generally, the SR tail clamp body 1 is made of an elastic material. Stretching the SR tail clamp body 1 for a long time is likely to cause the SR tail clamp body 1 to expand and deform or fall off the cable. Therefore, the present utility model provides an SR tail clamp reinforcement structure to enhance the stress response performance of the SR tail clamp body 1. When assembling the SR tail clamp body 1 and the bottom case 2, the operator first rotates the SR tail clamp body 1 until the plane 7 of the tail 6 is adapted to the protrusion 5 below the wire outlet hole 4, and passes the tail 6 through the wire outlet hole 4. At this time, the SR tail clamp body 1 and the flat part 21 of the bottom case 2 are in interference fit to complete the limitation of the increase in the deformation volume of the SR tail clamp body 1 under the action of stress, and enhance the structural durability of the SR tail clamp body 1; in addition, the plane 7 of the tail 6 of the SR tail clamp body 1 is rotated to the side away from the bottom case 2, and the insertion interface 11 of the face case 8 is inserted into the clamping groove 3, so that the upper surface of the support plate 9 abuts against the lower surface of the bottom case 2, the lower surface of the insertion plate 10 abuts against the groove wall of the clamping groove 3, and a gap 12 is left between the upper surface of the insertion plate 10 and the lower surface of the flat part 21 of the bottom case 2 to accommodate the protrusion 5; assuming that the SR tail clamp body 1 is stressed, the arrangement of the insertion plate 10 and the protrusion 5 can, on the one hand, limit the force deformation at the bottom of the clamping groove 3, thereby enhancing the service life of the SR tail clamp body 1 and reducing the risk of the SR tail clamp body 1 falling off the cable; on the other hand, the gap 12 left between the upper surface of the insertion plate 10 and the lower surface of the flat part 21 of the bottom case 2 can also enable the SR tail clamp body 1 to still protect the cable after thermal deformation.

[0026] In order to further enhance the fastening fit between the bottom case 2 and the face case 8, a groove 13 is opened at one end of the flat part 21 of the bottom case 2 away from the inclined part 22. Correspondingly, a clamping groove 18 formed by enclosing two convex blocks 14 is provided on the part of the fixing part 82 of the face case 8 that abuts against the flat part 21. Hereinafter, the two convex blocks 14 are respectively set as the first convex block 141 and the second convex block 142. A plurality of insertion parts 15 are provided on the first convex block 141. When the insertion interface 11 is inserted into the clamping groove 3, the groove 13 is clamped with the first convex block 141, one groove wall of the groove 13 is clamped with the clamping groove 18, and a plurality of insertion parts 15 are inserted into the groove 13 and abut against the groove bottom of the groove 13;

[0027] In this embodiment, in order to enhance the fastening fit between the flat portion 21 of the bottom shell 2 and the bracket of the SR tail card body 1, a plurality of receiving grooves 16 are formed in the hole wall of the wire outlet hole 4, so that when the SR tail card body 1 abuts against the hole wall of the wire outlet hole 4, the SR tail card body 1 and the receiving grooves 16 can be in extrusion fit, that is, the deformation of the SR tail card body 1 can be extruded into the receiving grooves 16, further enhancing the fastening fit between the flat portion 21 of the bottom shell 2 and the bracket of the SR tail card body 1; the upper aperture of the wire outlet hole 4 is larger than the lower aperture of the wire outlet hole 4, and the hole wall in the wire outlet hole 4 is continuous, so that when the operator passes the SR tail card body 1 through the wire outlet hole 4, the SR tail card body 1 can be more accurately passed through the wire outlet hole 4; let the end of the SR tail card body 1 passing through the wire outlet hole 4 be the tail portion 6, and a plurality of fixing strips 17 are fixedly arranged on both the face shell 8 and the bottom shell 2. In this embodiment, preferably three fixing strips 17 are arranged in parallel, and the fixing strips 17 abut against the side wall of the tail portion 6. Further, the end of the fixing strip 17 on the bottom shell 2 abutting against the outer wall of the tail portion 6 is designed to be arc-shaped; since one end of the tail portion 6 close to the face shell 8 is a plane 7, the end of the fixing strip 17 fixed on the face shell 8 abutting against the outer wall of the tail portion 6 is designed to be a plane 7, and the end of the fixing strip 17 fixed on the face shell 8 abutting against the outer wall of the tail portion 6 is a 45° bevel cut angle.
