[0002] An optical fiber array connector is an optical communication device used to connect multiple optical fibers, mainly for high-speed data transmission in optical fiber communication systems. The main function of the optical fiber array connector is to integrate multiple optical fibers in one connector to transmit multi-channel data simultaneously. Compared with single-core optical fiber connectors, optical fiber array connectors have higher data transmission capacity and smaller volume, and are widely used in fields such as high-density wiring in data centers, optical modules, and optical fiber sensing.

[0003] This experimental team has long browsed and studied a large number of relevant records and materials on the related technologies of optical fiber array connectors. At the same time, relying on relevant resources, a large number of relevant experiments have been carried out. After a large number of searches, it is found that the existing optical fiber connector structures are usually relatively complex, the assembly steps are cumbersome, the accuracy and stability of optical fiber arrangement are poor, and positioning inaccuracies are prone to occur especially in high-density applications. In addition, the space utilization rate of traditional connectors is not high, the miniaturized design of modules cannot be achieved, and the material durability and environmental adaptability are also weak, and the performance is prone to decline after long-term use.

[0004] In order to solve the problems commonly existing in this field, such as poor durability and environmental adaptability of optical fiber connectors, high structural complexity, etc., the present utility model is made. Summary of the Utility Model

[0009] Further, the vertical substrate includes a horizontally arranged horizontal plate, a vertically arranged vertical plate, and an arc plate for connecting the horizontal plate and the vertical plate. Among them, the horizontal plate and the vertical plate are perpendicular to each other, and through channels are respectively arranged inside the horizontal plate, the vertical plate, and the arc plate. Moreover, the through channels inside the flat plate, the vertical plate, and the arc plate are interconnected to form the placement cavity.

[0010] Further, one side wall of the vertical plate relatively far from the arc plate is the penetration wall, and a number of penetration holes are arranged horizontally on the penetration wall.

[0024] Embodiment 1: In combination with the attached Figure 1 、attached Figure 2 、attached Figure 3 、attached Figure 4 and attached Figure 5 In this embodiment, a 90-degree optical fiber array connector based on an injection molding process is constructed. The 90-degree optical fiber array connector includes a vertical substrate that fixes the optical fiber and supports the 90-degree turning of the optical fiber, a placement cavity that is arranged inside the vertical substrate and penetrates through both sides of the vertical substrate correspondingly, and a clamping plate that is vertically intercepted in the placement cavity.

[0025] A through hole is arranged on the clamping plate, and the optical fiber penetrates through both sides of the vertical substrate. At the same time, each optical fiber respectively penetrates out from the through hole. The clamping plate fixes the position of the optical fiber penetrating through the vertical substrate.

[0026] The vertical substrate includes a horizontally arranged horizontal plate, a vertically arranged vertical plate, and an arc plate used to connect the horizontal plate and the vertical plate. Among them, the horizontal plate and the vertical plate are perpendicular to each other. Through cavities are respectively arranged inside the horizontal plate, the vertical plate, and the arc plate, and the through cavities inside the flat plate, the vertical plate, and the arc plate are communicated with each other to form the placement cavity.

[0027] The side wall of the vertical plate relatively far from the arc plate is the penetration wall, and a number of penetration holes are arranged horizontally on the penetration wall. The optical fiber penetrates into the vertical substrate through these penetration holes in sequence. Each optical fiber respectively penetrates into the vertical substrate from the vertical plate of the vertical substrate and penetrates out from the horizontal plate of the vertical substrate. Among them, after the vertical substrate is injection molded with kovar alloy 4j29 as the raw material, the surface is obtained after gold plating treatment.

[0028] One end of the horizontal plate is connected to the arc plate, and at the same time, the other end of the horizontal plate is relatively far from the arc plate.

Each optical fiber uniformly passes through the corresponding through hole, so as to realize the array arrangement of optical fibers.

[0030] The 90-degree optical fiber array connector based on the injection molding process of the present utility model is reasonably designed. By adopting the combination of a horizontal plate, a vertical plate and an arc plate, the smooth 90-degree turning of the optical fiber is realized, stress and loss are reduced. The uniformly arranged through holes on the engaging plate ensure the precise positioning of the optical fiber, improving the stability of signal transmission. The vertical substrate is injection molded with kovar alloy 4j29 and plated with gold on the surface, having good electrical conductivity and corrosion resistance. The engaging plate uses quartz glass, having high light transmittance and thermal stability. The injection molding process not only improves the production efficiency and precision, reduces the cost, but also makes the installation and maintenance more convenient, meeting the requirements of high-density optical communication systems.
