Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, specifically a novel electrically isolated optical module. Background Technology

[0002] With the rapid development of optical communication technology, fiber optic communication systems have been widely used in data centers, metropolitan area networks, and other fields. Optical modules are key components in optical communication systems, used to convert between electrical and optical signals. They are primarily used in optical communication systems, especially in fiber optic transmission. An optical module typically consists of hardware and software components such as optical transceivers, PCB circuit boards, a package, a thermal management system, and monitoring and control circuits. These components work together to enable efficient and reliable optical signal transmission, making them an indispensable component in modern optical communication systems.

[0003] Existing optical devices have certain shortcomings in electrical isolation, making them susceptible to electromagnetic interference and affecting signal stability and transmission quality. For example, the continuity between the signal ground and the chassis ground of an optical device can lead to signal interference. Signal ground (connected to the optical device) is used for transmitting electrical signals. Chassis ground (connected to the module's chassis) is primarily used for power supply and equipment grounding, especially in high-frequency or high-speed signal transmission. Noise in the chassis ground can couple to the signal ground through the ground plane, degrading signal quality and potentially causing data errors, distortion, or loss, thus affecting system performance. Furthermore, issues such as ground potential difference, difficulty in troubleshooting, and impact on overall system performance also exist. Therefore, developing an optical module with excellent electrical isolation performance is particularly important. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a novel electrically isolated optical module, including a housing 1, a base skirt 10 at the bottom of the housing 1, the size of the base skirt 10 being adapted to both the housing 1 and the top cover 9, so that the base skirt 10 fixes the housing 1 and the top cover 9 together, a dustproof protective plug 11 is provided at one end of the housing 1, the dustproof protective plug 11 serves to prevent dust and protect the connection end of the adapter 4, an operating handle is provided on the surface of the dustproof protective plug 11, the operating handle facilitates the user to install and remove the dustproof protective plug 11, and a fixing buckle 16 is provided at the end of the housing 1 near the dustproof protective plug 11;

[0026] The housing 1 contains a PCB board 2. A base 3 is located on one side of the PCB board 2. An adapter 4 and a transmitter 5 are located at opposite ends of the base 3. A receiver 6 is located on one side of the base 3. The bottom of the PCB board 2 is connected to the transmitter 5 and receiver 6 via a connecting piece 12. A ground plane 13 is located on the surface of the transmitter 5, and a ground plane 14 is located on the surface of the receiver 6. An adjustment ring is also coupled and soldered to the surface of the adapter 4. An insulating ring 7 is tightly assembled with the adjustment ring. The insulating ring 7 is fitted onto the surface of the adapter 4, and its inner diameter is compatible with the size of the adapter 4. The device uses a physical method to isolate the signal ground from the housing ground. Its insulating ring 7 can adopt a single-sided flange design, which has the advantages of simple processing and low cost. The assembly gap adopts a transition fit, and the insulating ring 7 can be assembled onto the adapter 4 with a slight hand push force for easy installation. At the same time, its structure is small and does not require modification of its housing structure. The connection method between the adapter 4 and the standard connector remains unchanged, and the mechanical performance of the fixing method is not affected. Therefore, the assembly of this device does not become more complicated, effectively avoiding the situation of redesigning the PCB board 2 and increasing development costs and time.

[0027] One end of the adapter 4 is also provided with a buckle 8, and the inner side wall of the housing 1 is provided with a first slot 15. The buckle 8 is snapped into the first slot 15. The top of the housing 1 is provided with a top cover 9. The length of the top cover 9 is shorter than that of the housing 1 so that the gold fingers of the PCB board 2 inside the housing 1 are exposed. The top of the housing 1 is also provided with a second slot 17 for installing the top cover 9. The housing 1, the top cover 9 and the insulating ring 7 are all made of high insulation material. By using high insulation material, leakage current and electromagnetic interference are reduced, ensuring the stability and reliability of the optical module. This effectively solves the problem that in sensitive analog signal processing, the potential of the outer casing ground may fluctuate due to poor grounding or other factors, thereby affecting the stability of the signal ground and causing signal distortion.

[0028] In this utility model, the assembly steps of the device are as follows:

[0029] First, assemble the insulating ring 7 onto the adapter 4, then couple and solder the adapter 4 onto the base 3, then couple and fix the receiver 6 onto one side of the base 3, and then solder the transmitter ground 13 of the transmitter 5 and the receiver ground 14 of the receiver 6 together with other pins to the corresponding positions on the PCB board 2 through the connecting piece 12.

[0030] Next, insert the adapter 4 into the buckle 8 and install it into the housing 1 corresponding to the first slot 15. Then, use bolts and the second slot 17 to assemble the top cover 9 onto the housing 1. Next, assemble the base skirt 10 onto the housing 1 and the top cover 9 to strengthen the fixation. Finally, insert the dustproof protective plug 11 into one end of the housing 1 to complete the assembly.
