Description
Technical Field
[0001] The utility model belongs to the technical field of optical fiber connection, and particularly relates to an MPO / MTP optical fiber adapter module. Background Art
[0002] The data transmission and bandwidth pressure of the bearer network are increasing continuously. The transmission rate of the backbone network will be upgraded from 10G / 40G / 100G to higher speeds such as 200G / 400G. The multi-core optical fiber connector MPO / MTP has been widely used, and the requirement for interface density in the data center has also increased greatly.
[0003] Currently, the commonly used standard multi-core optical fiber connector interfaces include 8-core MPO / MTP interfaces, 12-core MPO / MTP interfaces, and 16-core MPO / MTP interfaces. In the data center, high-density optical fiber cabling usually uses an MPO / MTP adapter module to complete the connection of MPO / MTP-MPO / MTP pre-terminated optical cables and jumpers. In the existing mainstream solutions, one is to directly open MPO / MTP adapter installation holes on the front panel of the optical fiber distribution box; or use an MPO / MTP adapter module for cabling. The method of directly opening MPO / MTP adapter installation holes on the front panel affects the appearance, is inconvenient for disassembly and maintenance, and cannot achieve high-density cabling; the existing modular MPO / MTP adapter module often occupies a large space, has a complex structure, and is inconvenient to operate. Summary of the Utility Model
[0004] Aiming at the above-mentioned disadvantages, the purpose of the utility model is to provide an MPO / MTP optical fiber adapter module for connecting MPO / MTP-MPO / MTP pre-terminated optical cables and jumpers in a high-density scenario, which has a simple structure, occupies less space, and is convenient to disassemble.
[0005] In order to achieve the above technical purpose, the technical solution of the utility model is as follows:
[0006] An optical fiber adapter module includes an adapter bracket. The adapter bracket includes a first outer plate and a second outer plate. A connecting plate is connected between the first outer plate and the second outer plate. Between the first outer plate and the second outer plate, a partition plate is arranged on the connecting plate. The partition plate divides the space between the first outer plate and the second outer plate into a plurality of adapter slots, and an adapter (MPO / MTP adapter) is arranged in the adapter slot.
[0007] Between the first outer plate and the second outer plate, a plurality of (two or more) partition plates are arranged on the connecting plate. The plurality of partition plates are arranged in sequence and divide the space between the first outer plate and the second outer plate into a plurality of adapter slots.

The positioning chutes are arranged along the notch direction of the adapter slot, and the positioning bumps are located in the positioning chutes. The adapter is limited by the positioning bumps and the positioning chutes to prevent the adapter from displacing along the length direction of the adapter.
[0009] The adapter slot is provided with a clamping member, and the clamping member limits the adapter in the adapter slot.
[0010] The clamping member includes a notch piece, which is located at the notch of the adapter slot and is respectively clamped to the side walls of the adapter slot at both ends, so that the clamping member limits the adapter in the adapter slot.
[0011] The clamping member includes a side wall piece, which is located between the adapter and the side wall of the adapter slot; the side wall piece is provided with fins, one end of the fin is connected to the side wall piece, the fin faces the tail end of the adapter with the opening of the adapter, and the adapter slot is provided with fin locking holes, and the fin is clamped in the fin locking holes.

When the fin travels to the fin locking hole, the fin breaks free from the restraint of the inner wall of the adapter slot and is reset and clamped in the fin locking hole, so that the clamping member limits the adapter in the adapter slot. By squeezing the fin through the fin locking hole, the fin can enter between the adapter and the side wall of the adapter slot, and the disassembly of the adapter can be realized. The fin is clamped in the fin locking hole, which can not only clamp the adapter in the adapter slot to prevent the adapter from falling off from the notch of the adapter slot, but also prevent the adapter from displacing towards the tail end side of the adapter.
[0013] The side wall piece includes a first side wall piece and a second side wall piece. Both the first side wall piece and the second side wall piece are arranged on the notch piece. The notch piece is located at the notch of the adapter slot.

The module bracket is provided with a clamping hole for cooperating with the clamping block, and the clamping block on the clamping strip is clamped in the clamping hole. The clamping of the clamping block in the clamping hole enables the adapter bracket to be clamped in the bracket cavity of the module bracket. By pressing the clamping block through the clamping hole, the clamping strip deforms and the clamping block disengages from the clamping hole, and the disassembly of the adapter bracket can be realized.
[0019] The first outer plate or the second outer plate is provided with a guiding strip, and the guiding strip is arranged along the length direction of the adapter bracket. The module bracket is provided with a guiding chute for cooperating with the guiding strip, and the guiding strip slides in the guiding chute. The adapter bracket is limited by the guiding strip and the guiding chute to prevent the adapter bracket from displacing in the width direction of the adapter bracket; through the cooperation of the clamping block and the clamping hole, the adapter bracket is clamped in the bracket cavity.
[0020] The first outer plate or the second outer plate is provided with a lifting hole. By hooking a component such as a pull ring on the lifting hole, it is convenient for the adapter bracket to disengage from the bracket installation cavity.
