Description

Technical Field

[0001] This application relates to the field of optical cable junction boxes, and more particularly to an optical cable junction box and an optical fiber tray. Background Technology

[0002] An optical fiber junction box is a device used to connect, distribute, and schedule backbone optical cables and distribution optical cables in communication networks for communication systems, power systems, traffic control systems, and cable television systems.

[0003] Currently, Chinese utility model patent CN209992716U discloses a high-density, high-temperature resistant FTTX optical cable junction box, including a box body, a door, and a cover. The door and cover are installed in the box body. An optical cable splicing section is provided inside the box body and includes multiple optical fiber trays. Optical fiber receiving sections are arranged adjacent to the splicing section, each including a receiving backplate. The receiving backplate has winding posts and cable routing rings installed towards the door. The side faces of the optical fiber receiving sections near the box body sidewalls and the side faces of the splicing sections near the box body sidewalls maintain a certain distance from the side faces of the box body sidewalls. This utility model optimizes the structural design, greatly improving the junction box's capacity, accommodating high-density optical fibers, and simultaneously possessing excellent heat dissipation and improved heat resistance.

[0004] Fiber optic trays are used to split large-pair optical cables into small-pair optical cables. The large-pair optical cables are then wound onto winding posts. Because a large number of large-pair optical cables need to be stored in the optical cable junction box, the optical cables on the winding posts are easily confused and become tangled, affecting subsequent maintenance. Utility Model Content

[0005] To facilitate the differentiation of optical cables on the winding column and reduce the occurrence of optical cable tangling, this application provides an optical cable junction box and an optical fiber tray.

[0006] Firstly, the optical cable junction box provided in this application adopts the following technical solution:

[0007] An optical cable junction box includes a box body, two winding posts, and several slots for inserting trays. The winding posts and slots are disposed on the box body and include several cable management trays. The cable management trays can be sleeved on the winding posts and can slide along the length direction of the winding posts to be connected to the winding posts.

[0008] By adopting the above technical solution, staff can adjust the number of cable trays according to the different number of latches, and adjust the distribution of winding posts according to the number of cable trays. Large-pair optical cables are wound onto the winding posts and then onto the trays. After passing through the cable trays, large-pair optical cables can reduce the tangling on the winding posts and make it easier for staff to distinguish them, which is beneficial for the subsequent maintenance of the optical cable junction box.

[0009] Optionally, the cable tray is provided with a positioning component, which includes a positioning spring and a positioning bead. The winding post is provided with a plurality of positioning grooves along the length of the winding post. The inner circumferential surface of the cable tray is provided with a receiving groove. The positioning bead is slidably connected in the receiving groove. The positioning spring is used to engage the positioning bead in the positioning groove.

[0010] By adopting the above technical solution, the positioning component facilitates the positioning of the cable tray on the winding post. When the operator needs to move the cable tray on the winding post, the operator moves the cable tray directly. At this time, the positioning bead, which was originally located in the positioning groove, overcomes the elastic force of the positioning spring and leaves the positioning groove. Until the cable tray is aligned with the corresponding positioning groove again, the positioning bead will enter the positioning groove under the action of the positioning spring. The positioning component has a simple structure and is convenient for the operator to adjust the cable tray.

[0011] Optionally, the winding post is also provided with an anti-detachment disc, which is detachably connected to the end of the winding post away from the housing, and the anti-detachment disc prevents the cable management disc from detaching from the winding post.

[0012] By adopting the above technical solution, when it is necessary to adjust the number of cable trays on the winding post, the staff can first remove the anti-detachment trays, then match the number of cable trays with the number of trays, adjust the distance between the cable trays, and then install the anti-detachment trays on the winding post, thereby further reducing the occurrence of cable trays detaching from the winding post.

[0013] Optionally, the two winding posts are slidably connected to the housing in a direction that moves closer or further apart from each other, and the housing is also provided with a control component for controlling the distance between the two winding posts.

[0014] By adopting the above technical solution, the distance between the two winding posts can be adjusted by the control components, which tightens the originally loosely wound optical cable, reduces the drooping part of the optical cable, thereby reducing the occurrence of optical cable tangling and making it easier for staff to identify.

[0015] Optionally, the control component includes a bidirectional screw, a first bevel gear, a second bevel gear, and a throttle. The length direction of the bidirectional screw is parallel to the sliding direction of the winding post. The bidirectional screw is rotatably connected to the housing. The two winding posts are threadedly connected to the two ends of the bidirectional screw with opposite directions of rotation. The first bevel gear is disposed on one end of the bidirectional screw. The second bevel gear is rotatably connected to the housing and meshes with the first bevel gear. The throttle is disposed on the second bevel gear.

[0016] By adopting the above technical solution, when the operator needs to adjust the distance between the two winding posts, the operator can turn the handle, which drives the second bevel gear to rotate, the second bevel gear to rotate the first bevel gear, and the first bevel gear to rotate the bidirectional screw. The bidirectional screw changes the distance between the two winding posts. The control component has a simple structure and is easy to operate.

[0017] Optionally, the throttle is provided with an anti-accidental contact component, which includes a mounting tube and a release spring. The end of the second bevel gear is provided with a spline groove. The mounting tube is sleeved on the second bevel gear. The throttle is provided on the mounting tube. The end of the throttle facing the second bevel gear is provided with a spline. The release spring is used to keep the throttle away from the second bevel gear.

[0018] By adopting the above technical solution, in order to reduce the change in the distance between the two winding posts caused by the operator accidentally touching the throttle, the throttle is equipped with an anti-accidental touch component. When the operator needs to adjust the distance between the two winding posts, the operator needs to move the spline on the throttle over the spring force of the release spring towards the spline groove of the second bevel gear and engage it. The mounting tube restricts the sliding direction of the throttle, so that the spline can smoothly enter the spline groove. At this time, the operator can change the distance between the two winding posts by rotating the throttle.

[0019] Optionally, the spline is provided with a guide slope to facilitate entry into the spline slot.

[0020] By adopting the above technical solution, since the throttle can rotate freely on the second bevel gear, the spline of the throttle and the spline groove on the second bevel gear cannot be fully aligned at times. When the throttle needs to drive the second bevel gear to rotate, the spline needs to be inserted into the spline groove. The guide slope can facilitate the spline entering the spline groove.

[0021] Secondly, the fiber optic tray provided in this application adopts the following technical solution:

[0022] An optical fiber tray includes a tray body, on which a mating strip is provided for insertion into a slot in the aforementioned optical cable junction box.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Several cable management trays are detachably connected to the winding post. The cable management trays can be slidably connected to the winding post, so that the number of cable management trays is the same as the number of trays, so that different optical cables can be routed around different cable management trays, which facilitates the identification of optical cables and subsequent maintenance.

[0025] 2. The distance between the two winding posts can be adjusted by the control components, which reduces the length of the drooping part of the optical cable, fits the cable reel well, and reduces the tangling between optical cables;

[0026] 3. The anti-accidental touch component is used to reduce the accidental touch of the throttle by the operator during operation and improve the reliability of the optical cable winding on the cable management reel. Attached Figure Description
