[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 3 The present invention provides an embodiment of a plug-in type non-melting optical distribution box, comprising a housing 1 and a closing cover 2 mounted on the top thereof. Both sides of the housing 1 are fixedly connected with mounting plates to facilitate the stable installation of the housing 1. Both sides of the closing cover 2 are provided with blind grooves (such as the attached Figure 3 The front end of the housing 1 is fixedly connected with a positioning mechanism 3 for reinforcing the plug-in components, so that the external interface can be more stably fixed on the distribution box to avoid loosening of the interface due to external shaking. The front end of the housing 1 is fixedly connected with a plurality of plug interfaces 4, which facilitates the connection of external devices and improves the diversity of the interface. The interior of the housing 1 is fixedly connected with a combing mechanism 5 for arranging the wires, so that the internal wires or optical fibers can be arranged more neatly to avoid the risk of failure caused by clutter.

[0034] The combing mechanism 5 includes a limiting plate 1 501, the bottom of which is fixedly connected to the inner wall of the shell 1, providing stable support. The top of the limiting plate 1 501 is rotatably connected to the limiting plate 2 502, and the internal wires can be conveniently clamped by rotating the limiting plate 2 502. The adjacent sides of the limiting plate 1 501 and the limiting plate 2 502 are fixedly connected with magnets 503. When the two magnets 503 are close to each other, they will automatically adsorb, so that the wires are firmly fixed between the limiting plates, ensuring that the internal wires are not scattered due to shaking. The inner wall of the shell 1 is fixedly connected with multiple rubber rings 504, which can further fix the wires and play a double fixing role, thereby increasing the reliability of cable management. The four corners of the top of the shell 1 are fixedly connected with a snap-fit ​​mechanism 6 for fixing the closing cover 2, ensuring that the closing cover 2 will not fall off easily during use, thereby improving the sealing and protectiveness of the equipment.

[0035] refer to Figure 3 and Figure 4 The locking mechanism 6 includes four blocks 601, which are fixedly connected to the four corners of the top of the housing 1 to provide a firm support for the closing cover 2. The four corners of the closing cover 2 are each provided with a notch (as shown in the attached Figure 3(as shown), allowing block 601 to be smoothly inserted therein, thereby enhancing the securing effect of closing cover 2. The exterior of block 601 is slidably connected to the inner wall of the slot, enabling smooth sliding and facilitating the installation and removal of closing cover 2. A rotating block 602 is rotatably connected to the end of block 601 away from housing 1. Rotating block 602 can rotate within a range of 90 degrees to securely secure the cover. The bottom of rotating block 602 contacts the top of closing cover 2, allowing closing cover 2 to be securely closed on housing 1, enhancing the overall sealing of the device.

[0036] refer to Figure 2 The positioning mechanism 3 includes a fixing plate 301, which is detachably connected to the front end of the housing 1 by bolts, so that the user can disassemble and assemble the positioning mechanism 3 as needed. The inner wall of the fixing plate 301 is rotatably connected to a fixing rod 302. By rotating the fixing rod 302, its position can be more conveniently adjusted during the installation process to adapt to different wiring requirements. The outside of the fixing rod 302 is rotatably connected to a hollow tube 303. The hollow tube 303 can move flexibly with the rotation of the fixing rod 302, which is convenient for the fixing operation of the external cable. Torque springs 304 are sleeved on both sides of the outside of the fixing rod 302. When connecting the external cable, the torque spring 304 provides the necessary torque force to ensure a stable connection. One end of the torque spring 304 is fixedly connected to one side of the hollow tube 303, and the other end is fixedly connected to one side of the fixing plate 301. In this way, stable torque support can be provided to prevent loosening.

[0037] The front end of the hollow tube 303 is fixedly connected to a plurality of extension rods 305. Driven by the hollow tube 303, the extension rods 305 move downward to better support the external cables. The ends of the plurality of extension rods 305 away from the hollow tube 303 are fixedly connected to a support block 306. The support block 306 provides a stronger support force for the positioning block 307 to prevent the external cables from sliding. The outside of the support block 306 is fixedly connected to a positioning block 307. The positioning block 307 is used in conjunction with the pad 30802 to provide a stable positioning point for the external cables. The front end of the shell 1 is fixedly connected to a support assembly 308. The support assembly 308 includes a support plate 30801. The rear end of the support plate 30801 is fixedly connected to the front end of the shell 1, so that the positioning block 307 and the pad 30802 can be firmly fixed on the shell 1.

[0038] The top of the support plate 30801 is fixedly connected to a pad 30802. The pad 30802 has multiple grooves on the side away from the support plate 30801. These grooves are used to accommodate external cables, making the cables more stably fixed in the distribution box and avoiding the possibility of the cables loosening due to vibration or movement. One side of the positioning block 307 contacts one side of the pad 30802. When the connection is completed, it can effectively clamp the external cable, thereby improving the fixing effect of the cable. The pad 30802 and the positioning block 307 are both made of rubber. The rubber material has a certain degree of flexibility. While ensuring the fixing effect, it can also protect the cables and prevent the cables from being damaged due to long-term stress.

[0039] Working principle: When the device needs to be used, the rotating block 602 is rotated so that the rotating block 602 fits into the notch of the closing cover 2. At this time, the closing cover 2 can be removed through the blind slots on both sides of the closing cover 2;

[0040] At this time, the second limiting plate 502 can be rotated to place the wire inside the shell 1 between the arc-shaped groove between the first limiting plate 501 and the second limiting plate 502. Then, by rotating the second limiting plate 502, the two magnets 503 are brought close to each other for adsorption, thereby sealing the wire. Then, the placed wire is pressed from the top of the rubber ring 504, so that the wire enters the inside of the rubber ring 504 and is further restricted, thereby arranging the wire inside the shell 1. After arranging, the closing cover 2 is placed on the top of the shell 1. At this time, the block 601 can pass through the notch of the closing cover 2. Then, the rotating block 602 is rotated 90 degrees so that the rotating block 602 is pressed against the closing cover 2, thereby closing the closing cover 2.

[0041] Finally, connect the external interface to the plug interface 4, and generate torque through the torque spring 304, so that the hollow tube 303 will drive the extension rod 305 to move downward, and the extension rod 305 will drive the support block 306 to push the positioning block 307 against the external wire. At this time, the external wire will be restricted between the positioning block 307 and the pad 30802, located in the groove of the pad 30802, so that the external wire can remain stable and avoid loosening or falling off due to external shaking, thereby improving the connection stability and increasing the stability of the equipment.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
