Description

Technical Field

[0001] This utility model belongs to the field of communication lines, and more specifically, relates to a communication line wiring device. Background Technology

[0002] For communication lines, you must never twist the wire cores together and wrap them with tape like you would with electrical wires. You must use dedicated modular connectors (such as network modules and patch panels) and special tools (such as punch-down tools) for the corresponding line type to terminate the connection, so as to ensure the quality, stability and maintainability of signal transmission.

[0003] Chinese Patent CN217545554U discloses a junction box for communication lines, including a box body and multiple wiring assemblies. Each wiring assembly is fixedly connected to the box body and located inside the box. Each wiring assembly includes a mounting plate, a base plate, a conductive groove, a bracket, a lead screw, a pressure plate, and a first torsion post. The mounting plate is fixedly connected to the box body, the base plate is fixedly connected to the mounting plate, the conductive groove is fixedly connected to the base plate, the bracket is fixedly connected to the base plate, the lead screw passes through the bracket and is rotatably connected to the pressure plate, and is threadedly connected to the bracket. The first torsion post is fixedly connected to the lead screw and located at the upper end of the lead screw. This structural design effectively prevents the connection ends of multiple cables from touching inside the box, thus preventing short circuits and reducing safety hazards during use.

[0004] The above technical solution has the following drawbacks:

[0005] When wiring cables, the original cable (i.e., the cable to be wired) is often fixed in place during the previous installation, and its position and length are also determined based on the previous installation. Therefore, when wiring it, it is necessary to pull and limit its position before connecting it to the new cable. The workers need to first fix the original line to the junction box with bolts, then loosen the bolts, connect the new line to it, and then tighten the bolts. During this process, the original line is often prone to shrinking back. Therefore, it is often necessary to have two workers, one to wire the cable and the other to stretch and fix the original line, which causes inconvenience to the wiring work. Utility Model Content

[0006] To address the above deficiencies, this utility model provides a communication line wiring device, including a junction box. The junction box includes a hinged box body and a box cover. Two wire holes 1 and two wire holes 2 are respectively opened on the left and right sides of the box body and the box cover. A busbar is installed inside the box body. A wire clamp 1 for limiting wire I and a wire clamp 2 for limiting wire II are respectively installed on the left and right sides inside the box body.

[0007] Each of the wire clamps II is equipped with a locking device between it and the busbar. The wire inlet directions of the two locking devices are the same. The locking device includes a front shell and a rear cover that engage with each other. The two ends of the rear cover are respectively provided with through holes for wire inlet and outlet. The interior of the rear cover is hinged with two symmetrically distributed limiting cams by two spring pins. The limiting end of each limiting cam is provided with a limiting tooth. The interior of the rear cover is provided with two screw holes. The two screw holes are respectively used to limit the rotation of the limiting cams toward the wire inlet end by inserted screws.

[0008] Furthermore, the first telescopic rod and the second telescopic rod are respectively fixed to the nuts inside the corresponding rear covers by bolts passing through the two front shells.

[0009] Furthermore, the teeth of the limiting tooth are arc-shaped.

[0010] Furthermore, the middle of both the left and right ends of the box body is integrally formed with hanging lugs.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] By setting a locking device to limit the original line end, it is possible to achieve the limit treatment of preventing the original line from resetting and retracting after stretching without affecting the stretching of the original line towards the new line. One person can complete the wiring work, and there is no need for additional hand pressing or bolt fixing of the original line, making the wiring work much simpler. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 3 As shown, this embodiment provides a communication line wiring device, including a junction box. The junction box includes a box body 12 and a box cover 11 that are hinged together by a hinge and fixed by a snap fastener. The left and right sides of the box body 12 and the box cover 11 are respectively provided with two wire holes 1 and two wire holes 2 for passing new cables and original cables, respectively. A busbar 3 is installed inside the box body 12 (a network module can be used to install the stripped original cable, which will not be described in detail here). The left and right sides inside the box body 12 are respectively provided with a wire clamp 14 for limiting wire I and a wire clamp 2 for limiting wire II.

[0019] Each clamp II2 is equipped with a locking device 5 between it and the busbar 3. The rope feeding and locking directions of the two locking devices 5 are the same (e.g., ...). Figure 2 As shown, the rope enters from the right and exits from the left. The locking device 5 includes a front shell and a rear cover 51 that are locked together. The two ends of the rear cover 51 are respectively provided with through holes 52 for rope entry and exit. Inside the rear cover 51, two symmetrically distributed limiting cams 53 are hinged by two spring pins 54. Each limiting cam 53 has a limiting tooth 55 at its limiting end for "engaging" the cable surface. The limiting tooth 55 is as follows: Figure 3 As shown, the direction of cable entry is indicated by the arrow. When entering, the limiting cam 53 will not "engage" with the insulation layer on the surface of the cable, but will instead "engage" with it. This can be referenced from existing eccentric wheel anti-fall devices.

[0020] The back cover 51 has two screw holes inside. The two screw holes are respectively controlled by the inserted screws 56 to restrict the rotation of the limiting cam 53 toward the cable inlet end, thereby realizing the function of "only in, no out" cable. This realizes the limitation of the original line (cable) when tightening and preparing for wiring, so that it can only be pulled to the left, which facilitates the subsequent wiring work.

[0021] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
