Description

Technical Field

[0001] The present application relates to the field of optical fiber connection, and in particular to an optical fiber coupler and an optical fiber distribution frame. Background Art

[0002] Fiber optic coupler, also known as splitter, connector, adapter, fiber optic flange, is a device for detachable connection between optical fibers. It precisely connects the two end faces of the optical fiber so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and its intervention in the optical link minimizes the impact on the system. It is used to realize optical signal splitting / combining, or to extend the optical fiber link. It belongs to the field of optical passive components and is used in telecommunication networks, cable TV networks, user loop systems, and regional networks.

[0003] When connecting an optical fiber to a fiber optic coupler, in order to facilitate the connection of the optical fiber and the fiber optic coupler together, it is necessary to fix a fiber optic plug on the optical fiber. When connecting, the fiber optic plug is directly inserted into the socket of the fiber optic coupler to complete the connection between the optical fiber and the fiber optic coupler.

[0004] The method of fixing the fiber optic plug inserted into the fiber optic coupler is generally to install an elastic clip on the fiber optic plug, and then open a corresponding clip groove on the inner wall of the fiber optic coupler socket. When the fiber optic plug is inserted into the fiber optic coupler, the clip on the fiber optic plug is squeezed and retracted by the fiber optic coupler socket, and then moved to the position of the clip groove, the clip pops up and enters the clip groove, so that the fiber optic plug and the fiber optic coupler are connected together. When the fiber optic line is accidentally dragged, the clip itself is made of plastic. During the pulling process, the clip may bend and break, which may cause the fiber optic plug and the fiber optic coupler to separate or the connection to be unstable. Summary of the invention

[0005] The purpose of the present application is to solve the problem that when the optical fiber plug and the optical fiber coupler are connected together and the optical fiber line is accidentally dragged, the buckle itself is made of plastic.

[0037] When using the coupler body 2 to connect the optical fiber plug 1, first install the coupler body 2 on the optical fiber distribution box 7, and then insert the optical fiber plug 1 to be connected into the coupler body 2. After the optical fiber plug 1 is inserted into the coupler body 2, let the support mechanism 3 rotate on the coupler body 2, let the support mechanism 3 hold the tail of the optical fiber plug 1, and then let the support mechanism 3 and the coupler body 2 be fixed together, so that the support mechanism 3 limits and supports the optical fiber plug 1 inserted into the coupler body 2. When the support mechanism 3 and the coupler body 2 are fixed, the support mechanism 3 pushes the reinforcement mechanism 4, and the reinforcement mechanism 4 further fixes the limit block 6 on the optical fiber plug 1, so that the optical fiber plug 1 and the coupler body 2 are connected more firmly. After the optical fiber plug 1 is inserted into the coupler body 2, the support mechanism 3 on the coupler body 2 is used to fix and support the optical fiber plug 1, and then the reinforcement mechanism 4 is used to further fix the optical fiber plug 1 inserted into the coupler body 2, thereby improving the stability of the optical fiber plug 1 inserted into the coupler body 2, reducing the possibility of separation between the optical fiber plug 1 and the coupler body 2, and further improving the stability of the optical fiber plug 1 inserted into the coupler body 2.

[0038] Reference Figure 2 , Figure 3 and Figure 4 The support mechanism 3 includes two support blocks 31 symmetrically arranged on the coupler body 2, two symmetrical rotating shafts 35 are fixed on the coupler body 2, sliding grooves 34 are provided on the two support blocks 31, the rotating shafts 35 are located in the sliding grooves 34, and are slidably connected to the support blocks 31, connecting rods 32 are fixed on the two support blocks 31, a limiting ring 33 is fixed between the two connecting rods 32, and an opening is provided on one side of the limiting ring 33, and a clamping assembly 36 is provided between the support block 31 and the coupler body 2.

[0039] Before inserting the optical fiber plug 1 into the coupler body 2, first pull the limiting ring 33 to allow the limiting ring 33 to drive the connecting rod 32, and the connecting rod 32 to drive the supporting block 31, so that the supporting block 31 slides on the rotating shaft 35 using the sliding groove 34, and then rotate the supporting block 31 to make the supporting block 31, the connecting rod 32 and the limiting ring 33 form a ninety-degree angle with the coupler body 2, and then insert the optical fiber plug 1 into the coupler body 2, and then rotate the limiting ring 33 to allow the limiting ring 33 to drive the connecting rod 32 and the supporting block 31 to rotate, and then use the opening on the limiting ring 33, and then the tail of the optical fiber plug 1 enters the limiting ring 33, and then pushes The limiting ring 33 pushes the connecting rod 32, and the connecting rod 32 pushes the supporting block 31, so that the supporting block 31 moves on the clamping assembly 36, and the clamping assembly 36 fixes the supporting block 31. The limiting ring 33 pushes the tail of the optical fiber plug 1 toward the direction of the coupler body 2, and then the limiting ring 33 limits and fixes the tail of the optical fiber plug 1. After the optical fiber plug 1 is inserted into the coupler body 2, the limiting ring 33 is used to fix the tail of the optical fiber plug 1, thereby improving the stability of the optical fiber plug 1 inserted into the coupler body 2 and reducing the possibility of looseness between the optical fiber plug 1 and the coupler body 2.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The clamping assembly 36 includes a clamping block 361 arranged on the coupler body 2, and both ends of the clamping block 361 are fixedly connected to the coupler body 2. The clamping block 361 is hollow and has an open end close to the coupler body 2. A clamping plate 362 is slidably connected inside the clamping block 361, and a support spring 365 is arranged between the clamping plate 362 and the clamping block 361. Both ends of the support spring 365 are fixedly connected to the clamping plate 362 and the clamping block 361. Evenly distributed clamping teeth 363 are provided on the support block 31, and evenly distributed clamping teeth 364 are provided on the surface of the clamping plate 362 facing the support block 31. The clamping teeth 363 and the clamping teeth 364 correspond to each other. A pull rod is fixed on the clamping plate 362, and the pull rod passes through the clamping block 361 and is slidably connected to the clamping block 361.

[0041] When the limiting ring 33 is sleeved on the tail of the optical fiber plug 1, the limiting ring 33 is pushed, the limiting ring 33 pushes the connecting rod 32, the connecting rod 32 pushes the supporting block 31, the supporting block 31 passes between the clamping block 361 and the coupler body 2, and then the inclined surface of the clamping tooth 1 363 on the supporting block 31 contacts the inclined surface of the clamping tooth 2 364 on the clamping plate 362, and then the clamping plate 362 slides on the clamping block 361, and the clamping plate 362 squeezes the supporting spring 365, so that the inclined surfaces of the clamping tooth 1 363 and the clamping tooth 2 364 do not conflict with each other, under the push of the supporting spring 365, the supporting The engaging tooth 1 363 on the support block 31 is engaged with the engaging tooth 2 364 on the engaging plate 362, so that the support block 31 drives the connecting rod 32, and the connecting rod 32 drives the limiting ring 33 to abut against the tail of the optical fiber plug 1, so that the limiting ring 33 supports the tail of the optical fiber plug 1. By allowing the support block 31 to pass between the engaging block 361 and the coupler body 2, and then using the engaging plate 362 to fix the support block 31, it is convenient to drive the limiting ring 33 to abut against the tail of the optical fiber plug 1 by the supporting block 31, so that the limiting ring 33 can facilitate the abutment and support of the tail of the optical fiber plug 1.

[0042] Reference Figure 3 , Figure 4 and Figure 5 The reinforcement mechanism 4 includes two supporting blocks 41 symmetrically arranged on both sides of the coupler body 2, the supporting block 41 is fixedly connected to the optical fiber distribution box 7, a sliding block 42 is slidably connected to the supporting block 41, a fixed tooth 45 is fixed on the sliding block 42, a corresponding fixing groove is opened on the limit block 6, a synchronization component 44 is arranged on the sliding block 42, and a reset component 43 is arranged on the sliding block 42.

[0043] When pushing the support block 31, the support block 31 pushes the synchronization component 44, and the synchronization component 44 pushes the sliding block 42, and the sliding block 42 slides on the support block 41, and then the sliding block 42 drives the fixed teeth 45 to approach the coupler body 2, and then the fixed teeth 45 on the sliding block 42 contact the fixed groove on the limit block 6, and the teeth are used to further fix the limit block 6 on the optical fiber plug 1, so that the limit block 6 can further fix the optical fiber plug 1 inserted into the coupler body 2. When pushing the support block 31, the support block 31 pushes the synchronization component 44, and the synchronization component 44 drives the fixed teeth 45 on the support block 41 to limit the limit block 6 on the optical fiber plug 1, thereby further improving the stability of the optical fiber plug 1 inserted into the coupler body 2, and further reducing the possibility of looseness between the optical fiber plug 1 and the coupler body 2.

[0044] Reference Figure 3 and Figure 5The synchronization component 44 includes a sliding ring 441 arranged on the coupler body 2, and two symmetrical extrusion bevel blocks 442 are fixed on the sliding ring 441. An extrusion groove 443 is opened on the sliding block 42, and the extrusion groove 443 passes through the sliding block 42, and the extrusion block corresponds to the extrusion groove 443.

[0045] When pushing the support block 31, the support block 31 pushes the sliding ring 441, the sliding ring 441 moves on the coupler body 2, and then the sliding ring 441 drives the extrusion bevel block 442, the extrusion bevel block 442 enters the extrusion groove 443 on the sliding block 42, and then under the push of the inclined surface of the extrusion bevel block 442, the sliding block 42 moves toward the direction of the limit block 6, so that the fixed teeth 45 on the sliding block 42 are abutted and fixed to the limit block 6. By allowing the support block 31 to push the sliding ring 441 while supporting the support block 31, and allowing the extrusion bevel block 442 on the sliding ring 441 to push the sliding block 42, it is convenient for the sliding block 42 to drive the fixed teeth 45 to abut and limit the limit block 6 on the optical fiber plug 1.

[0046] Reference Figure 3 and Figure 5 The reset assembly 43 includes two reset blocks 431 symmetrically arranged on both sides of the sliding block 42. The reset block 431 is slidably connected to the sliding block 42. A reset spring 432 is arranged between the reset block 431 and the sliding block 42. Both ends of the reset spring 432 are fixedly connected to the reset block 431 and the sliding block 42.

[0047] When the extrusion bevel block 442 pushes the sliding block 42, the sliding block 42 slides between the two reset blocks 431, and then the reset block 431 squeezes the reset spring piece 432. When the support block 31 does not interfere with the sliding ring 441, the sliding block 42 moves to its original position under the push of the reset spring piece 432, and then the sliding block 42 interferes with the extrusion bevel block 442, allowing the extrusion bevel block 442 to push the sliding ring 441 to its original position. By using the reset spring piece 432 to push the sliding block 42, the sliding block 42 is kept away from the coupler body 2 when it is not pushed by the extrusion bevel block 442, thereby reducing the possibility that the fixed teeth 45 on the sliding block 42 hinder the movement of the limit block 6 during the insertion of the optical fiber plug 1.

[0048] Reference Figure 1 and Figure 2 A fiber optic distribution frame includes four support rods 9 that are symmetrical in pairs. The support rods 9 are located in a fiber optic distribution box 7. A sliding rail 8 is slidably connected to the support rods 9. The sliding rail 8 is fixedly connected to the fiber optic distribution box 7. Winding blocks 11 are fixed on the four support rods 9, and an opening mechanism 10 is provided in the fiber optic distribution box 7.

[0049] After the coupler body 2 is installed on the fiber optic distribution box 7, the optical fiber lines are arranged in the fiber optic distribution box 7, and the optical fiber lines are directly wound on the winding block 11 on the support rod 9. When there are many optical fiber lines placed in the fiber optic distribution box 7, the opening mechanism 10 is used to drive the support rod 9, and the support rod 9 moves on the sliding rail 8, and then the support block 31 drives the winding block 11 to move toward the edge of the fiber optic distribution box 7, so that the distance between adjacent winding blocks 11 becomes larger, and the optical fiber lines wound on the winding block 11 become longer. By sliding the support rod 9 on the sliding rail 8, the support rod 9 drives the winding block 11 to move, so that the length of the optical fiber lines left in the fiber optic distribution box 7 can be changed according to the needs. The length of the optical fiber lines wound on the winding block 11 can be changed, the number of turns of the optical fiber lines can be reduced, and the possibility of the optical fiber lines being entangled due to too many turns of winding can be reduced.

[0050] Reference Figure 1 and Figure 2 The opening mechanism 10 includes a rotating disk 101 rotatably connected to the optical fiber distribution box 7, and the rotating disk 101 is provided with four circumferentially distributed opening grooves 102. A moving column 103 is slidably connected in the opening groove 102, and the moving column 103 is fixedly connected to the corresponding support rod 9.

[0051] When the support rod 9 needs to be moved, the rotating disk 101 is rotated, and the rotating disk 101 drives the open slot 102 to rotate, and then the moving column 103 moves in the open slot 102. Under the push of the open slot 102, the corresponding moving column 103 drives the support rod 9 to slide on the sliding rail 8. By rotating the rotating disk 101, the rotating disk 101 uses the open slot 102 to drive the moving column 103 at the same time, so that the support rod 9 can be moved conveniently at the same time.

[0052] Working principle: First, install the coupler body 2 on the fiber optic distribution box 7. Before inserting the fiber optic plug 1 into the coupler body 2, first pull the limit ring 33 to let the limit ring 33 drive the connecting rod 32, and the connecting rod 32 drives the support block 31, so that the support block 31 slides on the rotating shaft 35 using the sliding groove 34, and then rotate the support block 31 to make the support block 31, the connecting rod 32 and the limit ring 33 form a ninety-degree angle with the coupler body 2, and then insert the fiber optic plug 1 into the coupler body 2, and then rotate the limit ring 33 to let the limit ring 33 drive the connecting rod 32 and the support block 31 to rotate, and use the opening on the limit ring 33, and then the tail of the fiber optic plug 1 enters the limit ring 33, and then push the limit ring 33, and the limit ring 33 pushes the connection Rod 32, connecting rod 32 pushes support block 31, support block 31 passes between clamping block 361 and coupler body 2, then the inclined surface of clamping tooth 1 363 on support block 31 contacts with inclined surface of clamping tooth 2 364 on clamping plate 362, then clamping plate 362 slides on clamping block 361, clamping plate 362 squeezes support spring 365, when the inclined surfaces of clamping tooth 1 363 and clamping tooth 2 364 are not in conflict, under the push of support spring 365, clamping tooth 1 363 on support block 31 and clamping tooth 2 364 on clamping plate 362 are clamped together, so that support block 31 drives connecting rod 32, connecting rod 32 drives limiting ring 33 to contact with the tail of optical fiber plug 1, so that limiting ring 33 supports the tail of optical fiber plug 1.

[0053] While pushing the support block 31, the support block 31 pushes the sliding ring 441, the sliding ring 441 moves on the coupler body 2, and then the sliding ring 441 drives the extrusion bevel block 442, the extrusion bevel block 442 enters the extrusion groove 443 on the sliding block 42, and then under the push of the inclined surface of the extrusion bevel block 442, the sliding block 42 moves toward the direction of the limit block 6, so that the fixed teeth 45 on the sliding block 42 resist and fix the limit block 6, when the extrusion bevel block 442 pushes the sliding block 42, the sliding block 42 slides between the two reset blocks 431, and then the reset block 431 squeezes the reset spring 432, when the support block 31 does not resist the sliding ring 441, under the push of the reset spring 432, the sliding block 42 moves to its original position.

[0054] After the coupler body 2 is installed on the optical fiber distribution box 7, the optical fiber lines are arranged in the optical fiber distribution box 7, and the optical fiber lines are directly wound on the winding block 11 on the support rod 9. When there are many optical fiber lines placed in the optical fiber distribution box 7, the opening mechanism 10 is used to drive the support rod 9, and the support rod 9 moves on the sliding rail 8, and then the support block 31 drives the winding block 11 to move to the edge of the optical fiber distribution box 7, so that the distance between adjacent winding blocks 11 becomes larger, and the optical fiber lines wound on the winding block 11 become longer.
