Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical module manufacturing technology, specifically a fixing component for TOSA optical modules. Background Technology
[0002] A TOSA optical module is an optical transmitting component that is mainly responsible for converting electrical signals into optical signals for transmission. It includes components such as semiconductor lasers, driving circuits, and optical lenses. The performance of a TOSA optical module directly affects the transmission distance, speed, and quality of an optical communication system. It is widely used in fields such as fiber optic communication and data centers to meet the needs of high-speed, high-capacity data transmission.
[0003] During the production and testing of TOSA optical modules, it is usually necessary to fix their external structure. Especially during the testing process, if the fixing effect is not good, abnormal shaking can easily affect the test results. Similarly, during production, if the components cannot be effectively fixed, it can easily cause abnormalities in operations such as soldering, which is quite inconvenient. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a fixing component for TOSA optical modules. It has the advantage of stably and effectively clamping TOSA optical module devices during production or testing. This solves the problem that TOSA optical modules usually require external structural fixing during production and testing. Especially during testing, if the fixing effect is not good, abnormal shaking can easily affect the test results. Similarly, during production, if the components cannot be effectively fixed, it can easily cause abnormalities in welding and other operations, which is quite inconvenient.
[0006] (II) Technical Solution
[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fixing component for a TOSA optical module includes a reference sleeve, a drive shaft extending to the outside and connected to a power component is rotatably disposed inside the reference sleeve, two drive sleeves with opposite directions of movement are connected to the outside of the drive shaft by threaded transmission, an oblong sliding hole is provided on the outside of the reference sleeve, a force measuring connecting sleeve extending to the outside of the reference sleeve through the oblong sliding hole is provided on the outside of the drive sleeve, and a fixing rod is inserted into and engaged with the end of the force measuring connecting sleeve;
[0008] A pressure sensor for compressive force testing is provided between the connection point of the force measuring sleeve and the fixed rod.
[0009] The force measuring connecting sleeve and the fixed rod are connected by an elastic snap-fit device. The fixed rod has two snap-fit points on its outside that are linked to the elastic snap-fit device. The two sides of the fixed rod are respectively provided with a curved surface and a flat surface clamping surface. The two snap-fit points are respectively located on the clamping surfaces.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, the pressure detection sensor is located on the back side of the clamping direction at the outer end of the inner side of the force measuring connecting sleeve, and the pressure detection sensor is protruding with the protruding surface forming a compression with the outside of the fixing rod. There is a gap between the end of the fixing rod and the inner wall of the force measuring connecting sleeve, and the rod is compressed with the pressure detection sensor.
[0012] Furthermore, the drive shaft is divided into a forward drive section, a reverse drive section, and a connecting section. The connecting section extends to the outside of the reference sleeve. The threads on the outside of the forward drive section and the reverse drive section are opposite and are respectively adapted to the two drive sleeves.
[0013] Furthermore, the elastic snap-fit component includes an elastic sleeve that is connected to the force-measuring connecting sleeve and extends to its inner wall. A compression spring is provided inside the elastic sleeve, and a restrictive snap-fit block is slidably connected inside the elastic sleeve. One end of the restrictive snap-fit block is pressed against the compression spring, and the other end extends into the interior of the fixing rod.
[0014] Furthermore, the inner side of the elastic sleeve is provided with a groove to limit the maximum movement distance of the restrictive block, and the end of the restrictive block extending into the fixed rod is arranged in an arc.
[0015] This utility model provides a fixing component for TOSA optical module devices. By setting a drive shaft, when it is necessary to clamp the TOSA optical module device, the drive shaft can be driven by an external drive component to drive the external drive sleeve to move. At this time, under the influence of the drive shaft, it can be ensured that the movement direction of the two drive sleeves is towards each other or away from each other. At this time, the clamping of the TOSA optical module device can be completed by the fixing rod connected to the force measuring connecting sleeve.
[0016] Meanwhile, when clamping TOSA optical module devices, the clamping scheme can be switched according to the external shape of the components. When the external shape of the component is circular, the arc surface is used for clamping, and when the external shape of the component is square, the flat surface is used for clamping. When it is necessary to switch the clamping surface, simply rotate the fixing rod to disengage it from the elastic snap-fit and move to the next snap-fit point.
[0017] During the clamping process, the fixing rod presses against the outside of the TOSA optical module device, thereby changing the force point at the connection between the fixing rod and the force measuring connecting sleeve. At this time, the pressure detection sensor bears the pressure. By detecting the pressure, the clamping and fixing can be kept relatively stable while preventing the fixing failure.
[0018] In summary, this component has the advantage of stably and effectively clamping TOSA optical module devices during production or testing. Attached Figure Description

[0025] Please see Figure 1-4 This utility model provides a fixing component for a TOSA optical module, including a reference sleeve 1. A drive shaft 2 is rotatably disposed inside the reference sleeve 1 and extends to the outside and is connected to a power component. Two drive sleeves 3 with opposite directions of movement are connected to the outside of the drive shaft 2 by threaded transmission. An oblong sliding hole is provided on the outside of the reference sleeve 1. A force measuring connecting sleeve 4 is provided on the outside of the drive sleeve 3 and extends through the oblong sliding hole to the outside of the reference sleeve 1. A fixing rod 5 is inserted into and engaged with the end of the force measuring connecting sleeve 4.
[0026] A pressure sensor for extrusion force testing is installed between the connection point of the force measuring sleeve 4 and the fixed rod 5.
[0027] The force measuring connecting sleeve 4 and the fixed rod 5 are connected by an elastic snap-fit 6. The fixed rod 5 has two snap-fit points on its outside that are linked to the elastic snap-fit 6. The two sides of the fixed rod 5 are respectively provided with a curved surface and a flat surface clamping surface, and the two snap-fit points are respectively located on the clamping surfaces.
[0028] Furthermore, the pressure detection sensor is located on the back side of the clamping direction at the outer end of the inner side of the force measuring connecting sleeve 4, and the pressure detection sensor is protruding with the protruding surface forming a compression with the outside of the fixing rod 5. There is a gap between the end of the fixing rod 5 and the inner wall of the force measuring connecting sleeve 4, and it is compressed with the pressure detection sensor.
[0029] Furthermore, the drive shaft 2 is divided into a forward drive section, a reverse drive section and a connecting section. The connecting section extends to the outside of the reference sleeve 1. The threads on the outside of the forward drive section and the reverse drive section are opposite and are respectively adapted to the two drive sleeves 3.
[0030] Furthermore, the elastic snap-fit member 6 includes an elastic sleeve 61 that is connected to the force-measuring connecting sleeve 4 and extends to its inner wall. A compression spring 62 is provided inside the elastic sleeve 61, and a restrictive snap-fit block 63 is slidably connected inside the elastic sleeve 61. The end of the restrictive snap-fit block 63 is pressed against the compression spring 62, and the other end extends into the interior of the fixing rod 5.
[0031] Furthermore, the inner side of the elastic sleeve 61 is provided with a groove to limit the maximum movement distance of the restrictive block 63, and the end of the restrictive block 63 extending into the interior of the fixing rod 5 is arranged in an arc.
[0032] Under normal conditions, the compression spring 62 is in a compressed state. The end of the limiting block 63 extends into the fixing rod 5 to assist in fixing it. At the same time, the arc at its end is designed to effectively push the limiting block 63 and further compress the compression spring 62 when the fixing rod 5 rotates. When it moves to the next engagement point, the end of the limiting block 63 extends into the fixing rod 5 again to assist in fixing it, so as to achieve the flipping of the clamping surface.
