Description

Technical Field

[0001] This utility model relates to the technical field of optical communication device bases, specifically an optical communication device base with an auxiliary positioning structure. Background Technology

[0002] Optical communication devices are key components in optical communication systems that convert optical signals into electrical signals. They are divided into two main categories: active devices and passive devices. Laser diodes are optoelectronic devices that can convert electrical signals into optical signals, and they are the core light source in optical communication systems.

[0003] Some devices on the market can be directly replaced using the laser diodes in the mounting base. Individual laser diodes in the array formed by the mounting base can also be replaced individually, improving the flexibility of use. The lens and laser diode are connected by a fixing rod, which can also limit the position of the laser diode and prevent it from moving during use.

[0004] However, in actual use, the laser diode moves when the fixing rod rotates, causing it to tilt inside the mounting base and become stuck, making it difficult to remove. Therefore, we propose a base for optical communication devices with an auxiliary positioning structure. Utility Model Content

[0005] The purpose of this invention is to provide a base for an optical communication device with an auxiliary positioning structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a base for an optical communication device with an auxiliary positioning structure, comprising a mounting base, a protective sleeve fixedly connected to the upper surface of the mounting base, a laser diode sleeved inside the protective sleeve, a limiting member fixedly connected to the inner wall of the protective sleeve, a fixing member provided on the upper surface of the limiting member, a lens provided on the upper surface of the fixing member, and a positioning assembly provided inside the protective sleeve, the positioning assembly comprising:

[0007] The positioning component is fixedly connected to the inner wall of the protective sleeve. The positioning component has a through groove inside, and the laser diode has a positioning groove on its outer surface. A sealing component is fixedly connected to the inner wall of the positioning groove, and an embedding groove is provided at the bottom of the fixing component.

[0008] Preferably, the end of the positioning member is provided through the bottom of the limiting member, and the position of the end of the positioning member corresponds to the position of the embedding groove, which allows the lens to be well limited.

[0009] Preferably, the outer surface of the seal is provided with a groove, and the seal is evenly distributed in a linear array on both sides of the inner wall of the positioning groove, which makes the sealing between the protective sleeve and the laser diode better.

[0010] Preferably, the position of the positioning groove corresponds to the position of the positioning element, and the size of the positioning groove is adapted to the size of the positioning element, which allows the positioning element to move well inside the positioning groove.

[0011] Preferably, the upper surface of the limiting member is provided with an auxiliary component, the auxiliary component including a groove, the groove being formed on the upper surface of the limiting member, and a protrusion being fixedly connected to the bottom of the fixing member.

[0012] Preferably, the protrusion is semi-circular, and the position of the protrusion corresponds to the position of the groove.

[0013] Preferably, the groove is located on the upper surface of the limiting member near the positioning member.

[0014] Compared with the prior art, the present invention provides a base for an optical communication device with an auxiliary positioning structure, which has the following advantages:

[0015] 1. This optical communication device base with an auxiliary positioning structure, in order to facilitate the replacement of the laser diode, has the lens installed from the top of the protective sleeve, with the bottom of the fixing component in contact with the upper surface of the limiting component, and the end of the positioning component inserted into the embedding groove, thus allowing the lens to be well limited inside the protective sleeve. The positioning groove is then aligned with the positioning component, and the laser diode is pushed in from the bottom of the protective sleeve. A vacuum is then drawn from inside the through groove, causing the air between the lens and the laser diode inside the protective sleeve to be extracted through the through groove, and the laser diode to move upwards inside the protective sleeve, allowing for quick installation. Furthermore, when replacing the laser diode, air is transmitted through the through groove, allowing the air inside the protective sleeve to push the laser diode downwards inside the protective sleeve for quick removal and replacement.

[0016] 2. The optical communication device base with auxiliary positioning structure, in order to avoid the bottom of the fixing part contacting the upper surface of the limiting part during lens installation, and to prevent the protrusion from being stuck into the groove, improves the sealing between the fixing part and the limiting part, and allows the air inside the protective sleeve to be better evacuated through the through groove.

[0025] like Figures 1-7 As shown, this utility model provides a technical solution: a base for an optical communication device with an auxiliary positioning structure, including a mounting base 1, a protective sleeve 2 fixedly connected to the upper surface of the mounting base 1, a laser diode 6 sleeved inside the protective sleeve 2, a limiting member 5 fixedly connected to the inner wall of the protective sleeve 2, a fixing member 3 provided on the upper surface of the limiting member 5, a lens 4 provided on the upper surface of the fixing member 3, and a positioning component 7 provided inside the protective sleeve 2. The positioning component 7 includes a positioning member 701, a through groove 702, a positioning slot 703, a sealing member 704, and an embedding slot 705.

[0026] In this embodiment of the present invention, the positioning member 701 is fixedly connected to the inner wall of the protective sleeve 2. The end of the positioning member 701 is provided through the bottom of the limiting member 5. The position of the end of the positioning member 701 corresponds to the position of the embedding groove 705, which allows the lens 4 to be well limited. A through groove 702 is provided inside the positioning member 701. A positioning groove 703 is provided on the outer surface of the laser diode 6. The position of the positioning groove 703 corresponds to the position of the positioning member 701. The size of the positioning groove 703 is adapted to the size of the positioning member 701, which allows the positioning member 701 to move well inside the positioning groove 703. A sealing member 704 is fixedly connected to the inner wall of the positioning groove 703. A groove is provided on the outer surface of the sealing member 704. The sealing members 704 are evenly distributed in a linear array on both sides of the inner wall of the positioning groove 703, which makes the sealing between the protective sleeve 2 and the laser diode 6 better. An embedding groove 705 is provided at the bottom of the fixing member 3.

[0027] Meanwhile, an auxiliary component 8 is provided on the upper surface of the limiting member 5. The auxiliary component 8 includes a groove 802, which is formed on the upper surface of the limiting member 5. The groove 802 is located on the upper surface of the limiting member 5 near the positioning member 701. The bottom of the fixing member 3 is fixedly connected to the protrusion 801, which is semi-circular. The position of the protrusion 801 corresponds to the position of the groove 802. This allows the bottom of the fixing member 3 to contact the upper surface of the limiting member 5 when the lens 4 is installed. At the same time, the protrusion 801 will be inserted into the groove 802, which improves the sealing between the fixing member 3 and the limiting member 5. This allows the air inside the protective sleeve 2 to be better evacuated through the through groove 702.

[0028] In this invention, during use, the lens 4 is installed from the top of the protective sleeve 2, with the bottom of the fixing member 3 contacting the upper surface of the limiting member 5. Simultaneously, the end of the positioning member 701 is inserted into the embedding groove 705, thus allowing the lens 4 to be well-positioned inside the protective sleeve 2. The position of the positioning groove 703 corresponds to the position of the positioning member 701. The laser diode 6 is pushed in from the bottom of the protective sleeve 2, and a vacuum is drawn from inside the through groove 702. This allows the air between the lens 4 and the laser diode 6 inside the protective sleeve 2 to be extracted through the through groove 702, causing the laser diode 6 to move upwards inside the protective sleeve 2. This allows for quick installation of the laser diode 6. Furthermore, when replacing the laser diode 6, air is transmitted through the through groove 702, allowing the air inside the protective sleeve 2 to push the laser diode 6 downwards inside the protective sleeve 2 for quick removal and replacement.

[0029] Furthermore, when installing the lens 4, the bottom of the fixing part 3 is brought into contact with the upper surface of the limiting part 5, and the protrusion 801 is inserted into the protrusion groove 802, which improves the sealing between the fixing part 3 and the limiting part 5, and allows the air inside the protective sleeve 2 to be better evacuated through the through groove 702.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
