Description

Technical Field

[0001] The utility model relates to the technical field of optical waveguide chips, in particular to an optical waveguide chip capable of preventing installation deviation. Background Art

[0002] An optical waveguide is a physical structure used to control and guide the propagation path of light. It is usually made of materials with a high refractive index and can guide light from one place to another without the need for an external light source or power source. The core principle of an optical waveguide is total reflection. When light is incident from a high refractive index medium into a low refractive index medium, if the angle of incidence is greater than a certain critical angle, the light will be completely reflected back into the high refractive index medium, thereby being confined to propagate in the waveguide. An optical waveguide chip is an integrated optical component that uses optical waveguide technology to integrate multiple optical functions on a small chip. It has the advantages of small size, low power consumption, high speed, and wide bandwidth. It is one of the key components of modern optoelectronic technology. This chip can realize multiple functions such as transmission, modulation, amplification, filtering, and switching of optical signals, and is widely used in communications, sensing, image processing, and other fields.

[0003] When producing an optical waveguide chip, in order to transmit signals and exchange data between the optical waveguide chip and an external circuit, pins are usually set on the optical waveguide chip. Since the pins are exposed to the outside and cannot be well protected, the pins are easily deformed under the action of external forces, and then their shapes and sizes may not match the installation positions, resulting in inability to accurately align during installation, which will cause the installation position of the optical waveguide chip to shift, resulting in reduced working stability and reliability of the optical waveguide chip. Therefore, in order to solve the above problems, an optical waveguide chip that can prevent installation shift is proposed. Utility Model Content

[0025] A protective mechanism is provided on the surface of the optical waveguide chip body 1, and the protective mechanism includes a protective plate 2, which is sleeved on the surface of the optical waveguide chip body 1, and a fixing plate 21 is fixedly connected to the surface of the protective plate 2. A through groove 22 is provided on the inner side of the protective plate 2, and the pin 11 is provided on the inner side of the through groove 22. A cover plate 23 is provided on the surface of the protective plate 2. The opening of the through groove 22 facilitates the placement of the pin 11, and then facilitates the protection of the pin 11 through the fixing plate 21 and the cover plate 23, so as to avoid the pin 11 from being offset during installation, and is more convenient for the use of the optical waveguide chip body 1.

[0026] Furthermore, the protective mechanism also includes a positioning rod 24, which is fixedly connected to the lower surface of the cover plate 23. A positioning groove 25 is provided on the inner side of the protective plate 2. A limiting rod 26 is movably connected to the inner side of the protective plate 2. A slot 27 is provided on the surface of the positioning rod 24. A spring 28 is fixedly connected to the surface of the limiting rod 26. The limiting rod 26 is movable and plugged into the slot 27, so that the cover plate 23 can be fixed on the protective plate 2, thereby realizing protection of the pin 11 by the protective plate 2 and the cover plate 23, thereby preventing the pin 11 from being deformed and causing displacement during installation.

[0027] Furthermore, the positioning rods 24 are in two groups and fixedly connected to the cover plate 23, the positioning grooves 25 are in four groups and opened on the inner side of the protective plate 2, and the limiting rods 26 are in four groups and movable on the inner side of the protective plate 2.

When the positioning rod 24 contacts the limiting rod 26, the limiting rod 26 will be squeezed, so that the limiting rod 26 can move on the inner side of the protective plate 2. At this time, the spring 28 is in a stretched state. When the positioning rod 24 makes the limiting rod 26 and the slot 27 relative to each other during the insertion process, the limiting rod 26 will Under the rebound effect of the spring 28, the limit rod 26 and the slot 27 are inserted into each other, thereby limiting the positioning rod 24, fixing the cover plate 23, and protecting the pin 11 through the fixing plate 21 and the cover plate 23; when the optical waveguide chip body 1 needs to be installed, the limit rod 26 is pulled to separate the limit rod 26 and the slot 27, so that the limit of the positioning rod 24 can be released, the cover plate 23 can be removed, and then the optical waveguide chip body 1 and the pin 11 can be taken out for installation;

[0032] By rotating the forward and reverse screws 3, the moving block 31 is limited by the limiting groove 32, and moves inside the limiting groove 32 under the action of the forward and reverse screws 3, and then the limiting plate 33 moves horizontally under the action of the moving block 31.
