Description

Technical Field

[0001] This utility model relates to the technical field of equipment mounting boxes, specifically to a mounting box for ONU equipment in a PON system. Background Technology

[0002] An ONU (Optical Network Unit) is a device used in optical fiber networks. It's a terminal device in optical fiber transmission technology used to convert signals transmitted through optical fibers into electrical signals, which are then transmitted to end-user devices such as computers and mobile phones. ONU devices, along with optical modems, are components of a PON (Physical Optical Network) system.

[0003] Existing ONU equipment mounting boxes on the market mainly align the device's interface with the box opening to facilitate wiring and connection to the internal ONU equipment. However, in actual use, the wiring passes through the box opening before connecting to the internal equipment, which significantly affects the stability of the wiring and the device itself. Without a limiting mechanism, unstable connections may occur. Therefore, we propose a mounting box for ONU equipment in a PON system. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an installation box for ONU devices in a PON system. This solves the problem that in actual use, when wiring passes through the box opening and connects to the internal equipment, it significantly affects the stability of the wiring and the device itself. Without a limiting mechanism, unstable connections may occur.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A mounting box for an ONU device in a PON system is provided, including a mounting box body 1. A plurality of mounting holes are provided on one side of the mounting box body. The mounting holes are of an oblong shape. A limit block is engaged inside the mounting hole. The limit block is made of rubber. A first engagement groove is provided on the outer wall of the limit block. A first limit hole is provided on one side of the limit block.

[0007] Preferably, a base plate is fitted inside the mounting box body, two limiting strips are fixedly installed on the top surface of the base plate, and the ONU device body is set on the top surface of the base plate. The ONU device body is snapped between the two limiting strips, and several through holes are opened on one side of the mounting box body.

[0008] Preferably, a supplementary light is fixedly installed on the top surface of the base plate, and a top cover is snapped onto the top surface of the mounting box body.

[0009] Preferably, a fixing seat is fixedly installed on the top surface of the base plate, and a second snap-fit ​​groove is opened on the top surface of the fixing seat. A first fixing plate is snapped into the inside of the second snap-fit ​​groove, and a number of second limiting holes are opened on one side of the first fixing plate.

[0010] Preferably, a fixing hole is provided on one side of the mounting box body, and a second fixing plate is fixedly installed inside the fixing hole. Several heat dissipation holes are provided on one side of the second fixing plate.

[0011] Preferably, fixing blocks are fixedly installed on both sides of the mounting box body, and threaded holes are opened on the top surface of the fixing blocks.

[0012] In summary, the present invention has the following main advantages:

[0013] 1. By setting a limit block, and through the design of the limit block and the first limit hole, the limit block can be removed before wiring installation, so that the wiring passes through the first limit hole and then the limit block is inserted into the installation hole. Its rubber material can restrict the wiring on the one hand, and protect the periphery of the wiring on the other hand, providing a buffer for the wiring to pass through.

[0014] 2. By setting a second limiting hole, the wiring can be doubly limited in conjunction with the first limiting hole, which further increases the stability of the device during installation and reduces the occurrence of wiring disconnection or even detachment. Attached Figure Description
