Technical Field

[0001] The utility model relates to the field of optical fiber connection equipment, in particular to an optical fiber adapter combination structure. Background Art

[0002] The optical fiber adapter is a connection device used to cooperate with the optical fiber plug to realize the cascading of two optical fibers. In the actual use process, multiple optical fiber adapters need to be used at the same time. The current practice is to insert multiple optical fiber adapters into the same panel, and then insert the panel into the patch panel. For example, a "optical fiber adapter connection structure, optical fiber wiring device, patch box and patch panel" disclosed in Chinese patent documents, with the publication number CN219676330U, the optical fiber adapter connection structure includes a panel and a plurality of adapter connectors, the adapter connector is provided with an adapter wiring hole for connecting the optical fiber plug, the patch panel includes an optical fiber adapter connection structure and a mounting plate, the adapter connector is provided with a snap-on assembly for inserting the panel, and the panel is provided with an elastic paddle for inserting the mounting plate of the patch panel. Therefore, during installation, multiple adapter connectors need to be inserted into the panel, and then the panel is inserted into the patch panel. This structure not only has many installation steps, but also because only the adapter wiring hole is an effective space, the panel and the adapter connector occupy a large amount of invalid space, resulting in a large waste of space in the patch panel and the chassis where the patch panel is installed. Utility Model Content

[0003] In order to solve the problems of complex installation and large space waste of the existing optical fiber adapter structure, a optical fiber adapter combination structure which does not require a panel and has a more compact structure is provided.

[0004] The technical solution provided by the utility model is as follows:

[0005] A fiber optic adapter combination structure is directly snapped onto a mounting plate of a distribution frame, the mounting plate being provided with a mounting opening for accommodating the main structure, comprising a main structure and a plurality of adapter wiring holes arranged in the main structure, the outer wall surface of the main structure being provided with a protruding structure and a spring sheet extending outward, one end of the spring sheet being connected to the outer wall surface, and the other end being a free end and extending toward the protruding structure, a snap-on space for snapping onto the mounting plate being formed between the end surface of the free end of the spring sheet and the protruding structure.

[0006] The mounting plate of the distribution frame is provided with a mounting port for installing the optical fiber adapter combination structure. During installation, the optical fiber adapter combination structure is pushed upward from the bottom of the mounting port of the mounting plate. The two sides of the mounting port press the springs toward the outer wall under the guidance of the outer side of the springs until the mounting plate stops at the protruding structure. At this time, the mounting plate is inserted between the protruding structure and the spring to complete the installation.

[0007] Preferably, the end surface is inclined or parallel to the upper surface of the mounting plate.

[0008] The inclined end face just butts against the edge of the installation opening, and the end face applies a force in both horizontal and vertical downward directions to the installation plate, so that the optical fiber adapter assembly structure and the installation plate are directly butted firmly, avoiding vibration caused by the gap between the optical fiber adapter assembly structure and the installation plate; the parallel end face has a larger contact area with the installation plate, which is not easy to cause damage to the shrapnel.

[0009] Preferably, the area of ​​the end face is larger than the cross-sectional area of ​​other parts of the spring sheet, so that the spring sheet can increase the area of ​​the end face while ensuring its elasticity.

[0010] Preferably, every two of the adapter wiring holes are arranged symmetrically to form an adapter wiring hole group, and several adapter wiring hole groups are arranged side by side. When using optical fiber adapters, multiple groups are often required, and adjacent optical fiber adapters share the same main structure to reduce the space occupied by the optical fiber adapters and reduce the volume of the optical fiber adapter combination structure.

[0011] Preferably, a first transverse partition is provided in the adapter wiring hole, and the first transverse partition divides the adapter wiring hole into two upper and lower accommodating grooves. A second transverse partition is provided above the first transverse partition, and the second transverse partition is arranged parallel to the first transverse partition and fixedly connected through a snap-fit ​​structure.

[0012] Preferably, the first transverse partition is provided with a first socket extending downward, and the second transverse partition is provided with a second socket extending upward, and the second socket is communicated with the first socket.

[0013] Preferably, the snap-fit ​​structure includes a snap-fitting part arranged on the second transverse partition and a square through hole arranged on the first transverse partition for accommodating the passage of the snap-fitting part. The snap-fitting parts are respectively arranged on two opposite side surfaces of the second transverse partition and extend toward the interior of the square through hole. The snap-fitting part includes an upward second abutting surface and a downward second guide surface. A snap-fitting part is arranged on a side wall surface of the square through hole away from the second transverse partition, and the snap-fitting part is provided with a first abutting surface facing downward and abutting the second abutting surface and a first guide surface facing upward.

[0014] The first transverse partition is integrally formed or fixedly connected with the main structure. When installing, the ceramic sleeve is placed in the first socket, and then the second transverse partition is installed, and the clips and the through holes are used for clipping. The square through holes and clips arranged on the opposite sides can fix the first transverse partition and the second transverse partition together, and play a role in positioning and preventing loosening, without the need for a separate positioning structure; in addition, the clips are arranged on the side wall of the square through hole away from the second transverse partition, so that the second transverse partition does not press the main structure outward during installation, thereby avoiding damage to the main structure and the second transverse partition during installation.

[0015] Preferably, the adapter wiring hole includes a pair of symmetrically arranged first transverse partitions and a pair of symmetrically arranged second transverse partitions, and the symmetrical surfaces of the pair of first transverse partitions are provided with a first vertical partition located at the lower part of the first transverse partition, and the symmetrical surfaces of the second transverse partitions are provided with a second vertical partition located at the upper part of the second transverse partition.

[0016] This structure is suitable for universal dual-port structure socket adapters, and the second vertical partition and the second horizontal partition are fixed together, which is convenient for one-piece molding. At the same time, it is convenient for people to take the second vertical partition by hand, so it is convenient for manual installation.

[0017] Preferably, the main structure is provided with a guide groove corresponding to the second vertical partition, and the guide groove can just accommodate the second vertical partition. The guide groove plays a guiding role during installation and plays a fixing role after the installation is completed.

The step is provided at the corner of the first transverse partition, and the second transverse partition is provided with an inwardly contracted square groove at a position corresponding to the step, and the wall of the square groove is in close contact with the side of the step.

[0019] The setting of the step not only ensures the flatness of the bottom of the second socket, but also plays a positioning role and reduces the edge width of the second transverse partition, thereby reducing the friction and extrusion between the second transverse partition and the main structure during installation.

[0020] Compared with the prior art, the needle protection assembly of this embodiment has the following beneficial effects:

[0021] The outer wall surface of the optical fiber adapter assembly structure is provided with a protruding structure and a spring piece. The optical fiber adapter assembly structure is directly inserted into the mounting plate of the distribution frame without the need for a panel transition, thereby reducing the installation process and improving space utilization.

DETAILED DESCRIPTION

[0034] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0035] For the convenience of description and understanding, the opening direction of the receiving groove 11 corresponding to the first transverse partition 21 is defined as vertically downward. Figure 4 , Figure 5 , Figure 6 , Figure 7 shown.

[0036] Embodiment 1, as Figure 1-Figure 5 As shown, a fiber optic adapter assembly structure is directly snapped onto the mounting plate 4 of the distribution frame, comprising:

[0037] The main structure 1 comprises an outer wall surface 16 located on the outer surface of the main structure 1;

[0038] Adapter wiring holes 2, which are arranged in the main structure 1 and are provided with twenty-four;

[0039] The protruding structure 14 is arranged at the outer wall surface 16 and located at the lower side of the mounting plate 4, and comprises a protruding structure abutting surface 141 facing the mounting plate 4 and abutting against the lower side of the mounting plate 4;

[0040] The spring piece 15 is located on the upper side of the mounting plate 4. One end of the spring piece 15 is connected to the outer wall surface 16, and the other end is a free end and extends downward and away from the outer wall surface 16. The spring piece 15 includes an end surface 151 located at the lower end of the spring piece 15 and facing the mounting plate 4. A clamping space 17 for clamping the mounting plate 4 is formed between the end surface 151 of the free end of the spring piece 15 and the protruding structure 14. A groove 152 recessed toward the outer wall surface 16 is also provided on the side of the spring piece 15 away from the outer wall surface 16, so as to facilitate pressing the spring piece 15 to disassemble the optical fiber adapter assembly structure;

[0041] When the protruding structure 14 and the spring sheet 15 are not clamped with the mounting plate 4, the side of the end surface 151 close to the outer wall surface 16 is inclined downward, and the thickness of the mounting plate 4 is greater than the distance between the side of the end surface 151 close to the outer wall surface 16 and the protruding structure abutting surface 141, that is, the minimum distance between the end surface 151 and the protruding structure abutting surface 141, and less than the distance between the side of the end surface 151 away from the outer wall surface 16 and the protruding structure abutting surface 141, that is, the maximum distance between the end surface 151 and the protruding structure abutting surface 141;

[0042] The area of ​​the end surface 151 is larger than the area of ​​the horizontal cross section of other parts of the spring piece 15;

[0043] Every two adapter wiring holes 2 are arranged symmetrically to form an adapter wiring hole group, and twelve adapter wiring hole groups are arranged side by side;

[0044] The mounting plate 4 of the distribution frame is provided with a mounting opening for installing the optical fiber adapter assembly structure. During installation, the optical fiber adapter assembly structure is pushed upward from the bottom of the mounting opening 41 of the mounting plate 4, and the two sides of the mounting opening press the spring sheet 15 toward the outer wall surface 16 under the guidance of the outer side surface of the spring sheet until the mounting plate 4 stops at the protruding structure 14. At this time, after the end face 151 is away from the outer wall surface for a certain distance, it is inserted between the protruding structure and the spring sheet to complete the installation.

[0045] Since the thickness of the mounting plate 4 is greater than the distance between the side of the end face 151 close to the outer wall surface 16 and the protruding structure abutting surface 141, and is smaller than the distance between the side of the end face 151 away from the outer wall surface 16 and the protruding structure abutting surface 141, the end face 151 just abuts against the edge of the mounting opening, and the end face 151 applies a force in both horizontal and vertical downward directions to the mounting plate 4, so that the optical fiber adapter assembly structure is directly and firmly abutted against the mounting plate 4, avoiding vibration caused by the gap between the optical fiber adapter assembly structure and the mounting plate.

The snap-fitting piece 222 includes an upward second abutting surface 2221 and a downward second guide surface 2222. A snap-fitting piece 213 is arranged on a side wall surface of the square through hole 212 away from the second transverse partition 22. The snap-fitting piece 213 is provided with a downward first abutting surface 2131 abutting against the second abutting surface 2221 and an upward first guide surface 2132.

[0048] A step 214 is provided on the first transverse partition 21 , and the upper surface of the step 214 is flush with the upper surface of the second transverse partition 22 .
