Abstract
Description
Technical Field
[0001] This application relates to the field of electronic technology, and in particular to a testing device for optical components. Background Technology
[0002] Optical components are core devices in optical communication networks. Their optical performance (such as insertion loss, return loss, and optical power stability) directly affects the operating efficiency and reliability of the entire system. Therefore, it is necessary to verify whether their performance meets the standards through optoelectronic performance testing.
[0003] During the photoelectric performance testing of optical components, it is necessary to electrically connect the DC power supply pins of the optical component under test to the test board to achieve circuit flow and signal transmission. In related technologies, displacement can easily occur between the DC power supply pins of the optical component and the gold fingers on the test board, resulting in unstable electrical connection between the optical component and the test board, which in turn leads to reduced test reliability. Utility Model Content
[0004] This application provides a testing device for optical components, which helps to improve the reliability of photoelectric performance testing of optical components.
[0005] This application provides a testing apparatus for optical components, comprising:
[0006] A test board mounting block, which is used to mount a test board;
[0007] A connecting component is detachably connected to the test board mounting block. The connecting component is provided with an optical component mounting slot for mounting the optical component under test.
[0008] An optical component crimping assembly, wherein the optical component crimping assembly is detachably connected to the connecting assembly.
[0009] In the case where the test board is mounted on the test board mounting block and the optical component under test is electrically connected to the test board in the optical component mounting slot, the connecting component is fixedly disposed on the side of the test board away from the test board mounting block, the optical component pressing component is fixedly connected to the connecting component, and at least a portion of the optical component pressing component extends into the optical component mounting slot and presses the optical component under test to restrict the movement of the optical component under test.
[0010] In this embodiment, a test board mounting block, a connecting component, and an optical component pressing component are included. The test board mounting block is used to mount a test board. The connecting component is detachably connected to the test board mounting block and is provided with an optical component mounting slot for mounting the optical component under test. The optical component pressing component is detachably connected to the connecting component. When a test board is mounted on the test board mounting block and the optical component under test, which is electrically connected to the test board, is mounted in the optical component mounting slot, the connecting component is fixedly disposed on the side of the test board away from the test board mounting block. The optical component pressing component is fixedly connected to the connecting component, and at least a portion of the optical component pressing component extends into the optical component mounting slot and presses down on the optical component under test to restrict movement of the optical component under test. In this way, the optical component under test (OST) that is electrically connected to the test board can be installed in the optical component mounting slot of the connecting component. The OST pressing component is inserted deep into the mounting slot to press the OST onto the OST, providing the pressing force required for testing and restricting the movement of the OST. This ensures that the pins of the OST are tightly attached to the pads of the test board, thereby preventing the OST from moving during the photoelectric performance test, reducing the risk of alignment deviation between the OST and the test board, and thus improving the reliability of the photoelectric performance test of the optical component.

[0021] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0023] During the photoelectric performance testing of optical components, the optical component under test needs to be electrically connected to the test board to enable circuit flow and signal transmission.
[0024] In related technologies, the DC power supply pins of optical components are usually connected to the test board by a crimping method. This involves manually aligning the DC power supply pins with the gold fingers on the test board and then pressing the pins down with a pressure block. However, this method does not completely fix the optical component after manual alignment. During the crimping process, displacement may occur, causing misalignment between the DC power supply pins of the optical component and the gold fingers on the test board. This can lead to test abnormalities or even short circuits on the test board, burning out the components and reducing the reliability of the optoelectronic performance test of the optical component.
[0025] Therefore, in related technologies, there is a problem of low testing reliability in the photoelectric performance testing process of optical components.
[0026] Based on this, please refer to Figures 1 to 2 This application provides a testing apparatus for optical components. For example... Figures 1 to 2 As shown, the testing device for the optical component includes at least a test board mounting block 110, a connecting component 120, and an optical component crimping component 130.
[0027] Among them, the test board mounting block 110 is used to mount the test board 200;
[0028] The connecting component 120 is detachably connected to the test board mounting block 110. The connecting component 120 is provided with an optical component mounting slot 1400, which is used to install the optical component 300 under test.
[0029] The optical component crimping assembly 130 is detachably connected to the connecting assembly 120.
[0030] In the case where a test board 200 is fixedly mounted on the test board mounting block 110 and a test optical component 300 is installed in the optical component mounting slot 1400, the test optical component 300 is electrically connected to the test board 200; the connecting component 120 is fixedly disposed on the side of the test board 200 away from the test board mounting block 110, the optical component pressing component 130 is fixedly connected to the connecting component 120, and at least a portion of the optical component pressing component 130 extends into the optical component mounting slot 1400 and presses down the test optical component 300 to restrict the movement of the test optical component 300.
[0031] The test board mounting block 110 can be any structure that can be used to mount the test board 200, and the shape, size, and material of the test mounting block can be set according to actual needs. For example, the test board mounting block 110 can be a rectangular metal base made of insulating material.
[0032] The upper test board 200 is used for photoelectric performance testing of optical components, and the test board 200 is detachably mounted on the test board mounting block 110. For example, the test board 200 can be detachably connected to the test board mounting block 110 by screws.
[0033] The test plate 200 is mounted on the test plate mounting block 110. Alternatively, the test plate 200 and the test plate mounting block 110 can be fitted together. Or, multiple test plate support columns 140 can be fixedly provided on one side of the test plate mounting block 110. The test plate 200 and the multiple test plate support columns 140 are detachably connected, and the multiple test plate support columns 140 support the test plate 200 so that a certain gap is formed between the test plate 200 and the test plate mounting block 110.
[0034] For example, if the test board mounting block 110 is a metal base, hexagonal copper pillars (i.e., test board support pillars 140) can be provided at the four corners of the metal base, and the test board 200 can be detachably connected to the hexagonal copper pillars at the four corners by screws.
[0035] When the test plate 200 is supported by multiple test plate support columns 140, in order to increase the support performance of the test plate 200, the above-mentioned test device may further include a test plate bottom support block 150. The test plate bottom support block 150 is detachably connected to the test plate mounting block 110. When the test plate 200 is fixedly mounted on the test plate mounting block 110, the test plate bottom support block 150 is located between the test plate mounting block 110 and the test plate 200, and the test plate bottom support block 150 supports the test plate 200.
[0036] For example, in the case where the test board 200 is detachably connected to the metal base via hexagonal copper pillars at the four corners of the metal base, a test board bottom support block 150 can be provided at the center of the side of the metal base on which the test board 200 is located.
[0037] The aforementioned connecting component 120 is detachably connected to the test mounting block, and the connecting component 120 is provided with an optical component mounting slot 1400, which is used to install the optical component 300 under test.
[0038] The aforementioned connecting component 120 can be any structure with an optical component mounting slot 1400 for mounting the optical component under test 300. For example, the connecting component 120 can be composed of four connecting blocks, and when the test plate 200 is mounted on the test mounting block, the four connecting blocks are arranged on the side of the test plate 200 away from the test mounting block to form the aforementioned optical component mounting slot 1400, and the four connecting blocks are detachably connected to the test mounting block.
[0039] The connecting component 120 is detachably connected to the test board mounting block 110. This connection can be achieved by directly connecting the connecting component 120 to the test board mounting block 110 using screws or similar means; alternatively, the connecting component 120 can be connected to the test board mounting block 110 via other structures. For example, if the metal base has a test board bottom support block 150, the connecting component 120 can be connected to the metal base via this test board bottom support block 150, such as by detachably connecting the connecting component 120 to the test board bottom support block 150 using screws.
[0040] The aforementioned optical component mounting slot 1400 can be any accommodating space capable of accommodating the optical component under test 300, and the shape and size of the optical component mounting slot 1400 can be set according to actual needs. When the optical component under test 300 is installed in the optical component mounting slot 1400, the optical component under test 300 is electrically connected to the test board 200. For example, the gold fingers on the test board 200 used for electrical connection with the pins of the optical component under test 300 can be located in the optical component mounting slot 1400, and when the optical component under test 300 is installed in the optical component mounting slot 1400, the pins of the optical component under test 300 can contact the gold fingers on the test board 200.
[0041] When the aforementioned optical component crimping assembly 130 is detachably connected to the connecting assembly 120, and a test board 200 is mounted on the test board mounting block 110, and a test optical component 300 electrically connected to the test board 200 is installed in the optical component mounting slot 1400, the optical component crimping assembly 130 is fixedly connected to the test optical component crimping assembly 130, and at least a portion of the optical component crimping assembly 130 extends into the optical component mounting slot 1400 and presses down on the test optical component 300, providing the crimping force required for testing the test optical component 300, thereby limiting the movement of the test optical component 300 and ensuring that the pins of the optical component are tightly attached to the test board pads.
[0042] For example, the aforementioned connecting component 120 can be composed of the four connecting blocks. The optical component pressing component 130 can include a clamping part and a cylinder assembly connected to the clamping part. The clamping part can be clamped onto any one of the connecting blocks. In this case, the piston rod of the cylinder assembly can be set perpendicular to the test board mounting block 110. When a test optical component 300 electrically connected to the test board 200 is provided in the optical component mounting slot 1400, the cylinder assembly can extend the piston rod toward the test board 200 until the piston rod touches the test optical component 300. This applies pressure to the test optical component 300 through the piston rod, restricting the movement of the test optical component 300 and ensuring that the pins of the optical component are tightly attached to the test board pads.
[0043] It should be noted that the optical component crimping assembly 130 can crimp the optical component under test 300 at any position. For example, if the optical component crimping assembly 130 includes a crimping block, the crimping block can be provided with a groove that can accommodate the optical component under test 300, and the groove wall of the crimping block can crimp the pins of the optical component under test 300.
[0044] In this embodiment, the optical component testing apparatus includes: a test board mounting block 110, a connecting component 120, and an optical component crimping component 130. The test board mounting block 110 is used to mount a test board 200; the connecting component 120 is detachably connected to the test board mounting block 110, and the connecting component 120 is provided with an optical component mounting slot 1400 for mounting the optical component 300 under test; the optical component crimping component 130 is detachably connected to the connecting component 120, wherein, on the test board... When a test board 200 is mounted on the mounting block 110 and a test optical component 300 electrically connected to the test board 200 is installed in the optical component mounting slot 1400, the connecting component 120 is fixedly disposed on the side of the test board 200 away from the test board mounting block 110, the optical component pressing component 130 is fixedly connected to the connecting component 120, and at least a portion of the optical component pressing component 130 extends into the optical component mounting slot 1400 and presses down the test optical component 300 to restrict the movement of the test optical component 300. Thus, the optical component under test 300, which is electrically connected to the test board 200, can be installed in the optical component mounting slot 1400 of the connecting component 120. The optical component pressing component 130 presses the optical component under test 300 into the mounting slot 1400, providing the pressing force required for testing and restricting the movement of the optical component under test 300. This ensures that the pins of the optical component are tightly attached to the pads of the test board, thereby preventing the optical component under test 300 from moving during the photoelectric performance test, reducing the risk of alignment deviation between the optical component under test 300 and the test board 200, and improving the reliability of the photoelectric performance test of the optical component.
[0045] In some embodiments, such as Figure 3 and Figure 4 As shown, the aforementioned optical component crimping assembly 130 includes:
[0046] Connecting base 131;
[0047] Optical component crimping part 132 is disposed on the first side of the connecting base 131;
[0048] Limiting member 133 is connected to connecting base 131;
[0049] When the optical component under test 300 is installed in the optical component mounting slot 1400, the connecting base 131 is fixedly connected to the connecting component 120, the optical component pressing part 132 presses the optical component under test 300 to restrict the movement of the optical component under test 300; and the limiting member 133 is connected to the optical component pressing part 132, and the limiting member 133 restricts the optical component pressing part 132 from moving in a direction away from the optical component under test 300.
[0050] In this embodiment, when the optical component pressing part 132 presses against the optical component under test 300, the limiting member 133 can restrict the movement of the optical component pressing part 132 in a direction away from the optical component under test 300, thereby ensuring that the optical component pressing part 132 can stably press against the optical component under test 300.
[0051] The connection base 131 and the connection component 120 are fixedly connected. The connection between the connection base 131 and the connection component 120 can be achieved by means of bolts, snaps or interference fit, so as to restrict relative movement between the connection base 131 and the connection component 120.
[0052] When the optical component under test 300 is installed in the optical component mounting slot 1400, the optical component pressing part 132 can press the optical component under test 300 to restrict the movement of the optical component under test 300, and the limiting member 133 can be connected to the optical component pressing part 132 to restrict the movement of the optical component pressing part 132 away from the optical component under test 300.
[0053] For example, the aforementioned connecting base 131 can be a connecting block with a through hole, the optical component pressing part 132 includes a pressing block and a pressing block elastic part, and the limiting member 133 includes a mounting plate. When the optical component to be tested 300 is installed in the optical component mounting groove 1400, one end of the mounting plate extends toward the center of the through hole and is fixedly connected to the elastic part, and the other end of the mounting plate is fixedly connected to the connecting base 131 by screws or the like. The pressing block presses down on the optical component to be tested 300 under the elastic force provided by the elastic part, and the mounting plate can restrict the entire optical component pressing part 132 from moving within the through hole.
[0054] In some embodiments, the limiting member 133 includes:
[0055] A limiting rod 1331 has a first end that passes through and is movably connected to a connecting base 131. The second end of the limiting rod 1331 is located on the second side of the connecting base 131. The second side of the connecting base 131 is opposite to the first side of the connecting base 131. The second end is used to drive the first end to move in a direction that is close to or away from the connecting base 131.
[0056] When the optical component pressing part 132 presses against the optical component under test 300, the first end of the limiting rod 1331 is connected to the optical component pressing part 132, and the limiting rod 1331 is locked in the connecting base 131 to restrict the optical component pressing part 132 from moving away from the optical component under test 300.
[0057] In this embodiment, a limiting rod 1331 is movably provided through the connecting base 131. When the optical component pressing part 132 presses against the optical component under test 300, the first end of the limiting rod 1331 is connected to the optical component pressing part 132. Thus, the limiting rod 1331 can restrict the optical component pressing part 132 from moving away from the optical component under test 300 by locking the limiting rod 1331 with the connecting base 131.
[0058] When the optical component to be tested 300 is installed in the optical component mounting slot 1400, the aforementioned limiting rod 1331 can be any rod-shaped structure that is movably disposed through the connecting base 131; and when the optical component pressing part 132 presses the optical component to be tested 300, the first end of the limiting rod 1331 is connected to the optical component pressing part 132. This connection can be either fixed or abutted by the first end of the limiting rod 1331 against the optical component pressing part 132.
[0059] For example, the limiting member 133 can be a cylindrical metal rod, and the optical component pressing part 132 can be a pressing block, with one end of the metal rod passing through the base 131 and fixedly connected to the pressing block.
[0060] When the optical component pressing part 132 presses against the receiving optical component 300, the limiting rod 1331 and the connecting base 131 can be locked to restrict relative movement of the limiting rod 1331 relative to the connecting base 131. For example, if the limiting rod 1331 is a metal rod fixedly connected to the pressing block, the metal rod and the connecting base 131 can be interference-fitted. When a force is applied to the metal rod in its extension direction, the metal rod can move relative to the connecting base 131, thereby adjusting the pressing part 132 of the optical component pressing part to press against the receiving optical component 300. When the force in the extension direction is stopped, the interference fit can restrict the metal rod from sliding.
[0061] In some embodiments, the limiting member 133 includes:
[0062] The screw is movably connected to the connecting base 131 by a thread, and the second end of the screw is located on the second side of the connecting base 131.
[0063] When the optical component crimping part 132 presses down on the receiving optical component 300, the first end of the screw is connected to the optical component crimping part 132.
[0064] In this embodiment, since the screw and the connecting base 131 are connected by a thread, the screw can be adjusted to move relative to the connecting base 131 along the extension direction of the screw, thereby adjusting the pressing force between the optical component pressing part 132 and the optical component 300 under test. When the screw is stopped, the screw is restricted from moving relative to the connecting base 131 under the action of the thread, thereby restricting the optical component pressing part 132 from moving away from the optical component 300 under test. The structure is simple and easy to implement.
[0065] When the optical component crimping part 132 presses against the optical receiver optical component 300, the first end of the screw is connected to the optical component crimping part 132. This connection can be either fixed or abutted against.
[0066] It should be noted that the adjustment screw described above can be achieved by directly rotating the screw to make the screw move relative to the connecting base 131 along the extension direction of the screw.
[0067] In some embodiments, the limiting member 133 further includes:
[0068] Rotating component 1332 is disposed on the second side of the connecting base 131 and fixedly connected to the second end of the screw. Rotating component 1332 is used to drive the first end of the screw to move in a direction close to or away from the connecting base 131.
[0069] In this embodiment, by fixing a rotating component 1332 to the second end of the screw, the screw can be easily adjusted by rotating the rotating component 1332.
[0070] The aforementioned rotating component 1332 can be any shape that is easy to rotate. For example, the rotating component 1332 can be a cylindrical rotating component 1332, and the side of the cylindrical rotating component 1332 used for rotation can be provided with texture or frosted structure, etc.
[0071] In the case where the limiting member 133 includes a screw and a rotating member 1332, the limiting member 133 may also include at least one limiting post 1333. The limiting post 1333 is fixedly connected to the connecting base 131 and is located between the connecting base 131 and the rotating member 1332. The limiting post 1333 is used to limit the rotating member 1332 from driving the screw to move in a direction close to the connecting base 131, thereby preventing the screw from applying excessive pressure to the optical component pressing part 132.
[0072] In some embodiments, the optical component crimping portion 132 includes:
[0073] The optical component crimping member is disposed on the first side of the connecting base 131 and is separate from the connecting base 131 and the limiting member 133.
[0074] At least one first guide shaft 1321, each first guide shaft 1321 passes through the connecting base 131 and is movably connected to the connecting base 131, one end of the first guide shaft 1321 is fixedly connected to the optical component crimping member, and each first guide shaft 1321 is used to guide the optical component crimping member to move in a direction close to or away from the connecting base 131;
[0075] When the optical component pressing part 132 presses against the receiving optical component 300, the first end of the limiting member 133 abuts against the optical component pressing part.
[0076] In this embodiment, when the optical component crimping member is separated from the connecting base 131 and the limiting member 133, the optical component crimping member can be guided to move in a direction close to or away from the connecting base 131 by at least one first guide shaft 1321, and the limiting member 133 can restrict the optical component crimping member from moving away from the optical component 300 under test by the first end of the limiting member 133 abutting against the optical component crimping member, thereby making the structure of the optical component crimping part 132 more stable and reliable.
[0077] The aforementioned optical component crimping member can be any structure that is separately disposed from the connecting base 131 and the limiting member 133, and is capable of crimping the optical component 300 under test installed in the optical component mounting slot 1400. For example, the optical component crimping member can be a square crimping block that is separately disposed from the connecting base 131 and the limiting member 133.
[0078] The aforementioned at least one first guide shaft 1321 may include only one first guide shaft 1321, or it may include multiple first guide shafts 1321. For example, when the aforementioned optical component crimping member is a square crimping block, a first guide shaft 1321 may be provided at each of the four corners of the side of the square crimping block near the connecting base 131, that is, the optical component crimping part 132 includes four first guide shafts 1321, thereby making the guidance more stable.
[0079] It should be noted that the first guide shaft 1321 may have a nut structure at the end away from the optical component crimping member. This nut structure is used to prevent the first guide shaft 1321 from detaching from the connecting base 131.
[0080] In some embodiments, the optical component crimping member includes:
[0081] Intermediate connector 1322 is fixedly connected to one end of at least one first guide shaft 1321;
[0082] A crimping block 1323 is disposed on the side of the intermediate connector 1322 away from the connecting base 131;
[0083] At least one second guide shaft 1324, each second guide shaft 1324 passes through the intermediate connector 1322 and is movably connected to the intermediate connector 1322, one end of the second guide shaft 1324 is fixedly connected to the crimping block 1323, and each second guide shaft 1324 is used to guide the crimping block 1323 to move in a direction close to or away from the intermediate connector 1322;
[0084] The elastic element 1325 is disposed between the crimping block 1323 and the intermediate connector 1322, and is used to provide the crimping block 1323 with a spring force toward the intermediate connector 1322.
[0085] When the optical component to be tested 300 is installed in the optical component mounting slot 1400, the pressing block 1323 presses down on the optical component to be tested 300, and the first end of the limiting member 133 abuts against the intermediate connecting member 1322.
[0086] In this embodiment, through the cooperation between the intermediate connector 1322, the pressing block 1323, at least one second guide shaft 1324 and the elastic member 1325, the elastic member 1325 can provide appropriate pressure to the pressing component when the pressing block 1323 presses down on the optical testing component 300, thereby reducing the risk of damage to the optical testing component 300 when the pressing component presses down on the optical testing component 300.
[0087] The aforementioned at least one second guide shaft 1324 may include only one second guide shaft 1324, or it may include multiple second guide shafts 1324. For example, when the aforementioned crimping block 1323 has a square structure, a second guide shaft 1324 may be provided at each of the four corners of the side of the crimping block 1323 near the connecting base 131, that is, the optical component crimping part 132 includes four second guide shafts 1324, thereby making the guidance more stable.
[0088] It should be noted that the second guide shaft 1324 may have a nut structure at the end away from the crimping block 1323. This nut structure is used to prevent the second guide shaft 1324 from disengaging from the intermediate connector 1322.
[0089] In some embodiments, the first end of the limiting member 133 is provided with a spherical structure, wherein when the optical component pressing part 132 presses the receiving optical component 300, the spherical surface of the spherical structure abuts against the optical component pressing part, thereby reducing the damage to the optical component pressing part caused by the limiting member 133 abutting against the optical component pressing part.
[0090] Of course, the first end of the aforementioned limiting member 133 can also be provided with other shapes, for example, the first end of the limiting member 133 can be provided with a planar structure, etc.
[0091] In some embodiments, the optical component crimping assembly 130 further includes:
[0092] At least one snap fastener 134 is provided, each snap fastener 134 is connected to the connecting base 131, and each snap fastener 134 includes a snap fastening end that is movably disposed.
[0093] When the connecting base 131 is disposed on the connecting assembly 120, if the latching end of at least one latching member 134 is in the first active position, the latching end of at least one latching member 134 is engaged with the connecting assembly 120, so that the connecting base 131 and the connecting assembly 120 are fixedly connected; if the latching end of at least one latching member 134 is in the second active position, the latching end of at least one latching member 134 is separated from the connecting assembly 120, so that the connecting base 131 and the connecting assembly 120 are separated.
[0094] In this embodiment, at least one snap fastener 134 is connected to the connecting base 131. By adjusting the movable position of the snap fastener end of the at least one snap fastener 134, the snap fastener end can be snapped or separated from the connecting component 120, making it convenient to disassemble the connecting component 120 and the connecting base 131.
[0095] The aforementioned latching member 134 can have any latching end in either of the aforementioned first movable positions. For example, the aforementioned optical component crimping assembly 130 may include a latching plate 1341, a connecting bolt 1342, and a spring 1343. One end of the latching plate 1341 is the latching end, the connecting bolt 1342 passes through the middle of the latching plate 1341, and both ends of the connecting bolt 1342 are respectively connected to the connecting base 131. The spring 1343 is disposed at the other end of the connecting base 131 and the latching plate 1341. The spring 1343 is used to provide elastic force between the connecting base 131 and the latching plate 1341. When the end of the latching plate 1341 with the spring 1343 is not pressed, the latching end can be in the first movable position; while when the end of the latching plate 1341 with the spring 1343 is pressed, the latching end can be in the second movable position.
[0096] In some embodiments, please also see Figure 5 and Figure 6 The aforementioned connection component 120 includes:
[0097] The optical component positioning block 121 has its first side detachably connected to the test board mounting block 110 and is used to position the optical component 300 under test mounted on the test board 200.
[0098] The crimping assembly connecting block 122 is detachably connected to the second side of the optical component positioning block 121 and the optical component crimping assembly 130. The second side of the optical component positioning block 121 is arranged opposite to the first side of the optical component positioning block 121.
[0099] The crimping component connecting block 122 and the optical component positioning block 121 together form the optical component mounting groove 1400.
[0100] In this embodiment, by setting the optical component positioning block 121 and the crimping component connecting block 122, the optical component 300 to be tested installed on the test board 200 can be positioned and is easy to disassemble and assemble.
[0101] The aforementioned optical component positioning block 121 can be any structure capable of positioning the installed optical component under test 300 to facilitate electrical connection between the optical component under test 300 and the test board 200. For example, a stepped surface can be provided inside the optical component positioning block 121 to position the optical component under test 300 within the optical component mounting slot 1400.
[0102] The first side of the aforementioned optical component positioning block 121 is detachably connected to the test board mounting block 110, which can be achieved by bolts or the like. For example, four through holes can be opened around the aforementioned stepped surface, and bolts can be passed through these four through holes to achieve a fixed connection between the optical component positioning block 121 and the test board mounting block 110.
[0103] The connection between the crimping assembly connecting block 122 and the optical component positioning block 121 can also be detachably connected by bolts or the like.
[0104] The aforementioned crimping assembly connecting block 122 is detachably connected to the optical component crimping assembly 130. This connection can be achieved through bolts, clips, or interference fits. For example, if the optical component crimping assembly 130 includes the aforementioned clip 134, the crimping assembly connecting block 122 can be provided with a snap-fit groove, and the snap-fit end of the clip 134 can snap into the snap-fit groove.
[0105] To facilitate understanding of the testing apparatus for optical components in the embodiments of this application, several application examples of the testing apparatus for optical components are provided below:
[0106] like Figures 1 to 6 As shown, the testing device for optical components includes a base assembly (including a test mounting block and a connection assembly 120) and a crimping assembly (i.e., an optical component crimping assembly 130).
[0107] The metal base (i.e., test board mounting block 110) is placed at the bottom, and four hexagonal copper pillars (i.e., test board support pillars 140) are installed at the four corners to elevate and fix the PCBA test board 200; the middle part of the metal base is locked with screws to install the PCBA bottom support block (i.e., test board bottom support block 150), which can fix and support the PCBA test board 200 and prevent the PCBA test board 200 from being deformed and damaged due to pressure applied during test crimping; the product positioning block (i.e., optical component positioning block 121) is placed in the test area of the PCBA test board 200 and fixed and locked to the PCBA bottom support block by screws passing through the PCBA test board 200;
[0108] The upper surface of the product positioning block has two stepped surfaces. The upper stepped surface 1211 has four through holes around its perimeter, through which four screws can be installed and fixed to the bottom support block by passing through the positioning holes on the PCBA test board 200. The inner perimeter of the upper stepped surface 1211 has eight screw holes for positioning and fixing the locking block. The lower stepped surface 1212 has four through holes, through which four screws can be installed and fixed to the bottom support block by passing through the positioning holes on the PCBA test board 200. The lower stepped surface 1212 has an internal slot, with the lower half of the slot sidewall being vertical. Its dimensions match the external dimensions of the BOX component under test, ensuring that the metal pins of the BOX component (i.e., the optical component) can be aligned one-to-one with the gold fingers of the PCBA test board 200. The upper half of the slot sidewall is angled outward to ensure that the product is placed smoothly into the slot without jamming.
[0109] The snap-locking block (i.e., the crimping assembly connecting block 122) has eight through holes around its perimeter, which can be fixed to the surface of the product positioning block with screws. The lower half of both sides has slots (i.e., snap-fit slots), and the opening size and shape of the slots match the snap-fit end of the snap-lock (i.e., snap-fit plate 1341); there is a triangular locking strip on the upper side of the slot.
[0110] The bottom of the pin clamping block (i.e., the clamping block 1323) is designed with a clamping platform, the distribution and size of which match the metal pins of the BOX optical component to be tested. The upper surface of the pin clamping block has seven circular holes in the middle, into which seven compression springs (i.e., elastic elements 1325) are embedded and installed. These springs are fixed to the pin clamping block spring block (i.e., the intermediate connecting piece 1322) by four sets of guide shafts (i.e., the second guide shaft 1324), flat washers, and hexagonal screws, simultaneously compressing the compression springs (i.e., elastic elements 1325). Four sets of guide shafts (i.e., the first guide shaft 1321), flat washers, and hexagonal screws are installed on the snap-fit mounting block (i.e., the connecting base 131). The roots of the guide shafts are fixed to the pin clamping block springs by threads. On the upper surface of the spring block, the snap-fit mounting block can slide up and down via the guide shaft; on each side of the snap-fit mounting block, a snap-fit is installed via a light shaft (i.e., connecting bolt 1342), and two round holes are distributed on the corresponding positions on both sides to embed and install two compression springs (i.e., springs 1343), with the other side of the spring contacting the inner side of the snap-fit; a threaded hole is opened in the center of the upper surface of the snap-fit mounting block, through which a screw rod (i.e., limit post 1333) can be installed, and there is a small threaded hole on each side of the threaded hole to install a limit screw; the screw rod passes through the snap-fit mounting block and contacts the upper surface of the foot pressure block spring block, and the height of screw rod screwing down depends on the height of the limit screw (i.e., limit post 1333) protruding from the upper surface of the snap-fit mounting block.
[0111] Brief instructions for use: Place the BOX optical component to be tested into... Figure 2 Place the entire crimping assembly into the slot of the product positioning block, then place the entire crimping assembly onto the base assembly and pinch it inwards. Figure 4 The upper part of the inner buckle opens the lower part of the buckle, allowing the buckle's hook to slide through. Figure 2 The locking strips on both sides of the buckle lock into the slot. When you release your hand, the spring force will push the upper part of the buckle outward, thereby causing the lower part of the hook to be tightly locked into the slot, ultimately fixing the entire crimping assembly to the base assembly. Then, tighten the screw to push the pin pressure block spring block downward. When the pin pressure block contacts the metal pin of the BOX optical component to be tested, if you continue to tighten the screw downward, the pin pressure block spring block will apply pressure to the pin pressure block through the compression spring, thereby increasing the pressure on the metal pin and achieving the ideal crimping effect.
[0112] After the test is finished, first loosen the screw, then pinch the upper part of the buckle. When the buckle hook moves out of the slot and its edge protrudes from the buckle limit block, lift it up to remove the entire crimping assembly. Then take the BOX optical assembly to be tested out of the product positioning block.
[0113] It should be understood that in this application, "at least one (item)" means one or more, and "more than" means two or more. "And / or" is used to describe the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can represent three cases: only A exists, only B exists, and both A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.
[0114] The above description, with reference to the accompanying drawings, illustrates some embodiments of this application, but does not limit the scope of the invention. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and spirit of this invention should be considered within the scope of this application.
