Description

Technical Field

[0001] This utility model relates to the field of optical module technology, specifically to an optical module pin header correction fixture. Background Technology

[0002] During the production and testing of optical modules, such as Figure 1 , Figure 2 The optical modules shown are prone to poor soldering or cold solder joints when soldered onto customer products or test boards due to the upward tilting of the optical module pin headers, which can lead to malfunctions and disconnections. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tooling for correcting the pins of an optical module header, so as to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A pin alignment fixture for an optical module includes a base and an alignment block. The upper surface of the base has two symmetrically arranged limiting blocks, and the gap between the two limiting blocks forms a limiting groove for limiting the optical module. The upper surface of the base has a recessed clearance space from the middle area of ​​the limiting groove to its tail end. The alignment block is fixed on the upper surface of the base and is located in front of the limiting groove. The lower surface of the alignment block has an alignment groove that matches each pin of the corresponding optical module pin and penetrates the rear end face.

[0005] The beneficial effects of this utility model are: When correcting the pin header pins of the optical module, the optical module is positioned within the limiting groove between two limiting blocks, and each pin of the optical module pin header is aligned with its corresponding correction groove in the correction block. Because the upper surface of the base has a recessed clearance space from the middle area of ​​the limiting groove to its tail end, the tail end of the optical module can be pressed down, causing it to descend a certain height. The end of the optical module with the pin header pins is then tilted upwards. Since each pin of the optical module pin header is positioned within its corresponding correction groove in the correction block, and each correction groove is specially machined according to the angle and shape of the pins, the pin header pins can be corrected during this process. This ensures that the angle and length of the pins are consistent after correction, preventing issues such as cold solder joints or desoldering, thus ensuring consistency with the dimensions agreed upon by the customer and improving product yield.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a limiting platform, which is lower than the correction block and used to limit the downward stroke of the optical module's tail end, is provided on the base in the area where the clearance space is located.

[0008] The further beneficial effects of the above are as follows: when the end of the optical module is pressed down, the end of the optical module will contact the limiting platform. The limiting platform ensures that the final height is consistent with each downward press, thereby correcting the height of each pin of the optical module pin header to ensure that the size is consistent with the customer's agreement. This can achieve 100% guarantee and thus improve the product yield.

[0009] Furthermore, the base has two first clearance slots arranged side by side in the clearance space area. The two first clearance slots are used to avoid the two mounting posts on the lower surface of the optical module. The distribution direction of the first clearance slots is the same as the distribution direction of the limiting blocks.

[0010] The further beneficial effect of adopting the above is that when the tail end of the optical module is pressed down, the first clearance groove can avoid the two mounting posts on the lower surface of the optical module, so as not to affect the height of the optical module being pressed down.

[0011] Furthermore, a second clearance groove is provided on the base between the two first clearance grooves. The second clearance groove is used to avoid the spring sheet on the lower surface of the optical module.

[0012] The further beneficial effect of adopting the above is that when the tail end of the optical module is pressed down, the second clearance groove can avoid the spring piece on the lower surface of the optical module, so as not to affect the height of the optical module being pressed down.

[0013] Furthermore, the corrective block is fixed to the base in a detachable manner.

[0014] Furthermore, the corrective block is fixed to the base using multiple screws.

[0015] The further beneficial effects of adopting the above are: easy to assemble and disassemble, and good sturdiness.

[0016] Furthermore, the rear end face of the correction block has a chamfer at the edge of each correction groove.

[0017] The further beneficial effect of adopting the above is that it can guide each pin of the optical module header, which is conducive to each pin of the optical module header entering the corresponding correction slot.

[0018] Furthermore, the corrective blocks are made of stainless steel.

[0019] Furthermore, the base is made of aluminum alloy. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1 like Figures 1 to 7 As shown, a pin alignment fixture for an optical module includes a base 1 and an alignment block 2. Two limiting blocks 110 are provided on the upper surface of the base 1. The two limiting blocks 110 are symmetrically distributed side by side, and the gap between the two limiting blocks 110 forms a limiting groove 120. The limiting groove 120 is used to limit the optical module, or it can be understood that the optical module 3 is stuck in the limiting groove 120 during alignment. A recessed clearance space 130 is provided on the upper surface of the base 1 from the middle area of ​​the limiting groove 120 to the tail end of the base 1. The alignment block 2 is fixed on the upper surface of the base 1 and is located in front of the limiting groove 120. Multiple alignment grooves 210 are provided on the lower surface of the alignment block 2, which are arranged in rows and penetrate through its rear end face. The cross-sectional shape of the alignment groove 210 matches the cross-sectional shape of the pin 310 of the optical module 3. Each alignment groove 210 corresponds to one pin 310 of the optical module 3 pin.

[0024] When correcting the pins 310 of the optical module 3, the optical module 3 is positioned within the limiting groove 120 between the two limiting blocks 110, and each pin 310 of the optical module 3 is positioned within the corresponding correction groove 210 of the correction block 2. Since the upper surface of the base 1 has a recessed clearance space 130 from the middle area of ​​the limiting groove 120 to its (base 1) tail end, the tail end of the optical module 3 (the end away from the pins 310) can be pressed down, causing the tail end of the optical module 3 to descend a certain height, while the end of the optical module 3 with the pins 310 is tilted upwards. Since each pin 310 of the optical module 3 is positioned within the corresponding correction groove 210 of the correction block 2, and each correction groove 210 is specially processed according to the angle and shape of the pins 310, the pins 310 can be corrected during this process, and the angle and length of the pins 310 are consistent after correction, avoiding phenomena such as poor soldering and desoldering of the product, so as to ensure consistency with the dimensions agreed upon by the customer and improve the product yield.

[0025] Example 2 like Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, this embodiment is a further improvement on embodiment 1, as detailed below: A limiting platform 140, which is lower than the correction block 2 and used to limit the downward stroke of the tail end of the optical module 3, is provided on the base 1 in the area where the clearance space 130 is located. When the tail end of the optical module 3 is pressed down, the tail end of the optical module 3 will contact the limiting platform 140. The limiting platform 140 ensures that the final height is consistent with each downward press, thereby correcting the height of each pin 310 of the optical module 3 pin header to ensure that the size is consistent with the customer's agreement. This can achieve 100% guarantee and thus improve the product yield.

[0026] Example 3 like Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, this embodiment is a further improvement on embodiment 1 or 2, as detailed below: The base 1 has two first clearance grooves 150 arranged side by side in the clearance space 130 area. The two first clearance grooves 150 are used to avoid the two mounting posts 330 on the lower surface of the optical module 3. The mounting posts 330 have internal threaded holes on their lower surfaces. The two mounting posts 330 on the lower surface of the optical module 3 are used to match the PCB board of the user end. The distribution direction of the first clearance grooves 150 is the same as the distribution direction of the limit block 110.

[0027] Furthermore, a second clearance groove 160 is provided on the base 1 between the two first clearance grooves 150. When the tail end of the optical module 3 is pressed down, the second clearance groove 160 can avoid the spring piece 320 on the lower surface of the optical module 3 so as not to affect the height of the optical module 3 when pressed down.

[0028] Example 4 like Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, this embodiment is a further improvement on embodiment 1, 2, or 3, as detailed below: The straightening block 2 is fixed to the base 1 in a detachable manner, for example, the straightening block 2 and the base 1 are fixed by multiple screws. Of course, this is just an exemplary description and a relatively common assembly method. In actual application, other methods, such as snap-fit, are not excluded.

[0029] Example 5 like Figure 4 As shown, this embodiment is a further improvement on any one of embodiments 1 to 4, as detailed below: The rear end face of the correction block 2 has a chamfer 220 at the edge of each correction slot 210, which can guide each pin 310 of the optical module 3 pin header, so that each pin 310 of the optical module 3 pin header can enter the corresponding correction slot 210.

[0030] Example 6 like Figures 3-7 As shown, this embodiment is a further improvement on any one of embodiments 1 to 5, as detailed below: The material of the straightening block 2 is preferably stainless steel, such as 304 stainless steel. Of course, this is just an example, and other grades of stainless steel may be used in actual applications. The material of the base 1 is preferably aluminum alloy, such as 6061 aluminum alloy. Of course, this is just an example, and other grades of aluminum alloy may be used in actual applications. The surface of the base 1 can be treated, such as black anodizing.

[0031] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
