Description

Technical Field

[0001] This invention relates to optoelectronic communication technology and its equipment, specifically a 24-channel transceiver integrated optical module based on spring-loaded electrical connections. Background Technology

[0002] Current optical communication devices suffer from numerous components and bulky size in some space-constrained applications. Furthermore, most current optical communication devices use a single optical channel, which limits information carrying capacity and transmission rate, and is not conducive to improving modulation bandwidth.

[0003] Optimizing the electrical connections of optical modules can effectively optimize the overall size. Therefore, optimizing the electrical connection design to support the optimization of optical module size is essential.

[0004] Therefore, it is necessary to provide a 24-channel transceiver optical module based on spring-loaded electrical connections to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a 24-channel transceiver integrated optical module based on spring-loaded electrical connections.

[0006] The technical solution is as follows:

[0007] A 24-channel transceiver optical module based on spring-loaded electrical connectors includes a PCB assembly module. The PCB assembly module is connected to a socket via a tail sleeve. An electrical connector is located below the PCB assembly module. The electrical connector includes an insulating base. Several spring-loaded electrical connectors are evenly arranged on the insulating base. Each spring-loaded electrical connector includes a lower connector embedded on the lower side of the insulating base. A connecting solder ball is provided on the lower connector. The lower connector is connected to an upper spring. The upper spring includes a vertical connecting part and a conductive end. The conductive end of the spring includes an upward slope. An arc-shaped conductive terminal is connected to the upward slope. The upward slope includes a first upward slope, a second upward slope, and an upward slope.

[0008] The spring-loaded electrical connector uses a reverse bending structure for the terminals to achieve effective elastic contact of the contacts in an ultra-low / high density space. The current channel consists of five basic structures from top to bottom: conductive terminal - raised slope - vertical connection - lower connector - connecting solder ball. The raised slope achieves elastic compression, while the vertical connection and lower connector achieve reliable fixation.

[0009] The spring-loaded electrical connector has a height of 1.0mm and an arrangement spacing of 0.8x0.8mm. By designing a reverse bending structure, the vertical connector, the lower connector, and part of the upward slope can coexist in the same height space, which can provide sufficient space for the fixing part and the elastic arm at the same time.

[0010] Furthermore, the slope of the first upward slope is 60-62°.

[0011] Furthermore, the slope of the second upward slope is 43-47°.

[0012] Furthermore, the slope of the uphill slope is 29-32°.

[0013] Furthermore, the socket is an MT socket.

[0014] Furthermore, the PCB assembly module is equipped with several high-speed chips, with a total of four high-speed chips arranged in pairs, connected by optical fibers to form a fiber-coupled PCB main structure.

[0015] Furthermore, the PCB assembly module is located in the lower shell.

[0016] Furthermore, a protective cover and a thermal pad are provided on the top of the PCB assembly module, and the protective cover and the thermal pad are held in place by the top cover.

[0017] Furthermore, the lower shell and the upper cover are fixedly connected by screws and snap-fit ​​structures.

[0018] Compared with existing technologies, the present invention is smaller in size and easier to miniaturize, while effectively improving the information carrying capacity and information transmission rate of optical communication devices. Attached Figure Description
