Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and in particular to an installation device for optical communication optoelectronic components. Background Technology

[0002] Optical communication optoelectronic components are miniaturized components that integrate optical transmitters and optical receivers. They achieve signal conversion through semiconductor lasers or photodiodes, and standard packaging includes circuit driving, clock recovery, and digital diagnostic functions.

[0003] Currently, traditional installation devices for optoelectronic components are bolts and clips. Bolt connections are complex to install, requiring installers to use various tools for tedious fixing and positioning operations, which is not only inefficient but also prone to installation errors. In addition, tightening bolts on-site may damage the optoelectronic component circuit board, affecting the normal operation of the optoelectronic component. Clip connections, on the other hand, are prone to loosening, displacement, or even falling off of the optoelectronic component. Utility Model Content

[0007] To achieve the above objectives, the installation device for the optical communication optoelectronic component of this utility model includes a fixed base plate, multiple positioning pins, and multiple positioning sleeves.

[0008] Multiple positioning pins are disposed on the circuit board of the optical communication optoelectronic component, and multiple positioning sleeves are disposed on the fixed base plate. The multiple positioning pins and multiple positioning sleeves are sleeved one-to-one.

[0009] The positioning pin is provided with a fixing mechanism, and the inner wall of the positioning sleeve is provided with an annular fixing groove. The fixing mechanism is detachably connected to the annular fixing groove.

[0010] Optionally, the circuit board of the optical communication optoelectronic component has a through hole, and the first end of the positioning pin is sleeved in the through hole;

[0011] The first end of the positioning pin is provided with an annular boss and an external thread.

The small ends of the multiple tapering holes are all arranged opposite to the annular fixing groove.

[0014] Multiple balls are arranged in a one-to-one correspondence with multiple tapered holes. The driving component is disposed within the positioning pin. The driving component can drive the balls to move from the large end to the small end of the tapered hole, so that the balls are partially located within the annular fixing groove.

[0035] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0036] While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0037] like Figure 1 and Figure 2 As shown, this utility model provides an installation device for an optical communication optoelectronic component. The optical communication optoelectronic component has a conventional structure, including a circuit board and multiple electronic components disposed on the circuit. The installation device for the optical communication optoelectronic component includes a fixed base plate 1, multiple positioning pins 2, and multiple positioning sleeves 3. The fixed base plate 1, as part of the optical communication equipment, is pre-fixed on the optical communication equipment. The installation and fixing of the fixed base plate 1 are all conventional methods, serving as the mounting base for the optoelectronic component. Alternatively, other panels in the optical communication equipment can be used as the fixed base plate 1, and the multiple positioning sleeves 3 can be installed and fixed on the fixed base plate 1 according to preset positions. The multiple positioning pins 2 are all disposed on the circuit board of the optical communication optoelectronic component, and the multiple positioning pins 2 and multiple positioning sleeves 3 are sleeved one-to-one. Through the mutual matching and installation of the multiple positioning pins 2 and positioning sleeves 3, the optical communication optoelectronic component can be quickly positioned, simplifying the positioning process and improving installation efficiency. The positioning pins 2 are provided with a fixing mechanism 21, and the inner wall of the positioning sleeves 3 is provided with an annular fixing groove 31. The fixing mechanism 21 and the annular fixing groove 31 are detachably connected. After the positioning pin 2 is inserted into the positioning sleeve 3, it is locked inside the positioning sleeve 3 by the fixing mechanism 21, preventing the optical communication optoelectronic component from loosening or falling off. This simplifies the installation process of the optical communication optoelectronic component and reduces the manpower and time costs during installation. The positioning pin 2 can be pulled out of the positioning sleeve 3 by separating the fixing mechanism 21 from the annular fixing groove 31, thus realizing the disassembly and assembly of the optical communication optoelectronic component. This invention combines positioning and fixing into one unit, reducing the size of the installation device and improving the efficiency of positioning and fixing the optical communication optoelectronic component, thereby improving installation efficiency.

[0038] like Figures 1 to 3 As shown, the circuit board of the optical communication optoelectronic component has a through hole, and the first end of the positioning pin 2 is fitted into the through hole. An annular boss 22 is provided on the positioning pin 2 near the first end, and the first end of the positioning pin 2 has an external thread. See also... Figure 3 After the first end of the positioning pin 2 passes through the through hole, the annular boss 22 abuts against the first side of the circuit board of the optical communication optoelectronic component. A nut 23 is connected to the external thread. After the nut 23 is tightened, it abuts against the second side of the circuit board of the optical communication optoelectronic component. Before the optical communication optoelectronic component is installed, the positioning pin 2 is fixed on the circuit board. After the circuit board passes the inspection, it is inserted and installed with the positioning sleeve 3.

[0039] like Figure 3 As shown, the fixing mechanism 21 includes a drive assembly and multiple balls 24. The positioning pin 2 is a hollow tubular structure with openings at both ends. Multiple tapering holes 41 at the same height are formed on the side wall of the positioning pin 2. The diameter of the tapering holes 41 gradually decreases radially along the positioning pin 2. The smaller ends of the multiple tapering holes 41 are all positioned opposite to the annular fixing groove 31. The multiple balls 24 are correspondingly positioned in the multiple tapering holes 41. The drive assembly is located inside the positioning pin 2. The drive assembly can drive the balls 24 to move from the larger end to the smaller end of the tapering holes 41, so that part of the balls 24 are located within the annular fixing groove 31. After the drive assembly drives the balls 24 to their limit position within the tapering holes 41, the multiple balls 24 are engaged in the tapering holes 41 and the annular fixing groove 31. The drive assembly can use a screw and eccentric locking structure to maintain the current position of the balls 24, fixing the positioning pin 2 and the positioning sleeve 3 together.

[0040] Furthermore, such as Figure 3 As shown, a receiving cavity 42 is formed inside the positioning pin 2. The driving assembly includes a conical driving head 25, which is slidably disposed within the receiving cavity 42 along the axial direction of the positioning pin 2. The large end of the tapered hole 41 communicates with the receiving cavity 42. The driving head 25 abuts against the ball 24. When the driving head 25 moves along the axial direction of the positioning pin 2, the conical driving head 25 gradually compresses the space of the receiving cavity 42, forcing the ball 24 to move from the large end to the small end of the tapered hole 41, thereby partially positioning the ball 24 within the annular fixing groove 31. Specifically, see... Figure 3 When the drive head 25 moves upward, it presses the ball 24 against the tapered hole 41. At this time, part of the ball 24 abuts against the annular fixing groove 31, and the positioning pin 2 is fixed in the positioning sleeve 3. When the drive head 25 moves downward, it releases the ball 24. When the positioning pin 2 is pulled out, the ball 24 is squeezed back into the tapered hole 41 and the receiving cavity 42 by the compression of the positioning groove. The fixed relationship between the positioning pin 2 and the positioning sleeve 3 is released, and the two can be separated. See also Figure 4 The annular groove is preferably an arc-shaped groove that matches the shape of the ball 24, so as to prevent the ball 24 from getting stuck when it slides back into the tapered hole 41 and the receiving cavity 42.

[0041] like Figure 3As shown, the drive assembly also includes a screw 26, which is coaxially sleeved and threadedly connected to the locating pin 2. The first end of the screw 26 is located outside the locating pin 2, and the second end is connected to the drive head 25. Rotating the screw 26 drives the drive head 25 to rotate while simultaneously moving it axially along the locating pin 2. When the drive head 25 moves upward, causing the ball 24 to reach its limit position, the threaded connection between the screw 26 and the locating sleeve 3 locks the current position of the drive head 25. A drive rod 27 is hinged to the first end of the screw 26. Rotating the drive rod 27 to a position perpendicular to the screw 26 allows the screw 26 to rotate, achieving a labor-saving drive without the need for tools.

[0042] Preferably, there are two tapered holes 41 and two ball bearings 24. The two tapered holes 41 are arranged symmetrically about the central axis of the positioning pin 2, which simplifies the structure of the device while ensuring the stability of the fixation.

[0043] This invention features multiple positioning pins 2, each mounted on the circuit board of an optical communication optoelectronic component. These pins 2 are individually fitted with positioning sleeves 3. Through the matching installation of the positioning pins 2 and the positioning sleeves 3, rapid positioning of the optical communication optoelectronic component is achieved, simplifying the positioning process and improving installation efficiency. Each positioning pin 2 is equipped with a fixing mechanism 21, and the inner wall of the positioning sleeve 3 is provided with an annular fixing groove 31. The fixing mechanism 21 and the annular fixing groove 31 are detachably connected. After the positioning pin 2 is inserted into the positioning sleeve 3, the fixing mechanism 21 locks the positioning pin 2 within the positioning sleeve 3, preventing the optical communication optoelectronic component from loosening or falling off. This simplifies the installation process and reduces labor and time costs during installation. Separating the fixing mechanism 21 from the annular fixing groove 31 allows the positioning pin 2 to be pulled out of the positioning sleeve 3, thus enabling the disassembly of the optical communication optoelectronic component. The disassembly and assembly operations are convenient.
