[0021] The following is combined with Figure 1-6 This application is described in further detail.

[0022] The embodiment of the present application discloses a hanging type optical fiber access device with firm connection.

[0023] Reference Figure 1 A hanging optical fiber access device with a secure connection comprises a wall-mounted cabinet 1 and an optical fiber terminal box 11, wherein the optical fiber terminal box 11 is fixedly installed inside the wall-mounted cabinet 1, and an optical fiber fixing seat 2 is fixedly installed inside the wall-mounted cabinet 1, as shown in the attached Figure 2-3 As shown, the optical fiber fixing seat 2 is provided with a plurality of wire clamping grooves 21, and the wire clamping grooves 21 are provided with a locking mechanism 3, and the locking mechanism 3 includes a locking tongue 31 and a fastening screw 32. Figure 4 As shown, a telescopic hole 22 is provided on the inner wall of one side of the wire clamping slot 21, and a locking tongue 31 is slidably mounted on the telescopic hole 22. The outer end of the locking tongue 31 is provided with a chamfered surface 33, and the chamfered surface 33 is arranged outwardly toward the notch position of the wire clamping slot 21. Figure 5 As shown, the chamfered surface 33 is used to guide the optical fiber to be pushed into between the end face of the locking tongue 31 and the wire clamping groove 21 and control the locking tongue 31 to retract. A reset spring 34 is provided between the inner end of the locking tongue 31 and the telescopic hole 22. The reset spring 34 is used to drive the locking tongue 31 to extend to compress the optical fiber. A screw hole 23 connected to the inner wall of the telescopic hole 22 is provided on the surface of the optical fiber fixing seat 2. A fastening screw 32 for locking the position of the locking tongue 31 is threadedly connected to the screw hole 23.

[0024] The implementation principle of a firmly connected hanging optical fiber access device in the embodiment of the present application is as follows:

[0025] 1. Install the fiber optic terminal box: First, the fiber optic terminal box 11 is fixedly installed inside the wall-mounted cabinet 1 as a core component of the hanging fiber optic access device, and is provided with a fiber optic interface for connecting optical fibers.

[0026] 2. Fiber positioning: Introduce the optical fiber into the wall-mounted cabinet 1 and place it in the cable groove 21 of the optical fiber fixing seat 2. The cable groove 21 is designed to fix and guide the optical fiber.

[0027] 3. Locking operation: The optical fiber is fixed by the locking mechanism 3. The locking mechanism 3 is composed of a locking tongue 31 and a fastening screw 32. When the optical fiber is placed into the cable slot 21, it is introduced through the chamfered surface 33, and the locking tongue 31 is pushed to slide along the telescopic hole 22 on the inner wall of the cable slot 21. The locking tongue 31 on the telescopic hole 22 slides to a proper position through the chamfered surface 33 at its outer end.

[0028] 4. Adjustment and fixation: When the optical fiber is in place, the return spring 34 at the inner end provides elastic force to ensure that the outer end plane of the locking tongue 31 presses the optical fiber cable in the clamping groove 21, thereby achieving elastic clamping and fixation of the optical fiber.

[0029] 5. Fastening connection: The fastening screw 32 is screwed into the screw hole 23 on the surface of the optical fiber fixing seat 2, and the screw hole is connected to the telescopic hole 22. The inner end of the fastening screw 32 contacts the side wall of the locking tongue 31, and the locking tongue 31 is locked by tightening the screw, thereby strengthening the fastening of the optical fiber.

[0030] 6. Enhanced stability: Through the design of the locking mechanism 3, longitudinal fastening and limiting are achieved, thereby enhancing the stability of the optical fiber connection end and effectively avoiding accidental disconnection due to vibration or other external forces.

[0031] Through the above steps, the technical solution solves the problem of optical fiber connection stability, and through the design of the longitudinal fastening structure and the limiting structure, the reliability and maintenance convenience of the optical fiber access equipment are significantly improved.

[0032] like Figure 6 As shown, a locking bevel 35 is provided on the side wall of the locking tongue 31, and the locking bevel 35 is arranged outwardly toward the screw hole 23, and the locking bevel 35 is slidably matched with the inner end of the fastening screw 32. The locking bevel 35 is a slope surface formed by chamfering or groove processing, and the locking bevel 35 is matched with the inner end of the fastening screw 32. In this way, when the fastening screw 32 is locked, the locking tongue 31 can be pushed out by the locking bevel 35 to clamp the optical fiber.

[0033] An anti-loosening spring 36 is provided between the fastening screw 32 and the screw hole 23 to make the fastening screw 32 and the screw hole 23 more tightly connected and prevent the fastening screw 32 from loosening and falling off due to thread gap.

[0034] An elastic pad 24 is provided on the inner wall of the other side of the clamping groove 21, and the elastic pad 24 is arranged opposite to the locking tongue 31. The elastic pad 24 can protect the optical fiber cable and enhance the friction force, and can reduce the noise generated by the locking tongue 31 popping out and colliding when the cable is removed.

[0035] The telescopic hole 22 is a square hole, which can be used for circumferential positioning when the lock tongue slides. The wire clamping groove 21 is a rectangular groove, which is convenient for processing and manufacturing.

[0036] The front of the wall-mounted cabinet 1 is provided with a cabinet door 12, and wiring operations can be performed when the cabinet door 12 is opened. The bottom of the wall-mounted cabinet 1 is provided with a wiring hole 13 for bottom wiring of optical fibers. The interior of the wall-mounted cabinet 1 is provided with a cabinet rail 14, which is generally four vertical rails. The cabinet rail 14 is provided with a plurality of mounting holes 15 for indicating different mounting heights. The mounting holes 15 are bolted to install partitions of different heights, and the optical fiber terminal box 11 is placed on the partition. The optical fiber fixing seat 2 is fixedly installed on the edge of the partition to facilitate combing of the optical fiber.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
