Description

Technical Field

[0001] This utility model relates to a testing fixture, and more particularly to a camera testing fixture and testing equipment. Background Technology

[0002] Cameras undergo rigorous functional testing during mass production to ensure stable product performance and quality. During testing, test fixtures are commonly used auxiliary tools to hold the product under test and mate it with the testing components. Test fixtures effectively improve testing efficiency, ensure testing stability, and reduce errors caused by human operation, and are widely used in the production and testing of various types of cameras.

[0003] In related technologies, camera test fixtures typically consist of a cover plate and a base, with the camera under test fixed between them for convenient testing. However, in practical applications, to bring out the camera's interface for connection to the testing components, holes are usually drilled in the fixture, and adapter pins are placed inside these holes. The adapter pins contact the camera's interface, and the interface connection is achieved through multiple signal transfers for camera testing. Because the signal needs to pass through multiple transfer points, the transmission speed of the line may be affected, especially in testing scenarios requiring high-speed data transmission. Multiple transfers may lead to signal quality degradation, affecting the accuracy and efficiency of the test. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a camera testing fixture and testing equipment that can improve the data transmission speed of the line.

[0005] This utility model provides a camera testing fixture for connecting a camera to be tested to a testing component. It is characterized by including a fixture cover plate, a fixture base, a product mounting base, an adapter plate, and a connecting pin seat.

[0006] The fixture cover plate is detachably connected to the fixture base. The product mounting base is disposed at one end of the fixture base near the fixture cover plate and is used to fix the camera to be tested. The adapter plate is disposed at one end of the fixture cover plate away from the product mounting base and is used to electrically connect with the detection component.

[0007] One end of the connecting pin holder passes through the fixture cover plate and is used for electrical connection with the interface of the camera under test. The other end of the connecting pin holder is electrically connected to the adapter plate and is used to electrically connect the camera under test to the testing component.

[0008] In one embodiment, the fixture base has a limiting cavity at one end near the fixture cover plate for limiting the displacement of the product mounting seat, and the product mounting seat is embedded in the limiting cavity.

[0009] In one embodiment, the camera test fixture further includes a resilient buffer component. The fixture cover has a mounting groove, and the buffer component is at least partially located within the mounting groove for pressing against the camera to be tested mounted on the product mounting base during testing.

[0010] In one embodiment, the buffer assembly includes a pressure block disposed in the mounting groove. Both ends of the pressure block are provided with mounting flanges. One of the mounting flanges is engaged with the side of the fixture cover plate away from the fixture base, and the other mounting flange is engaged in the mounting groove. The end of the pressure block near the product mounting seat has a receiving groove for accommodating and pressing against the camera to be tested.

[0011] In one embodiment, the camera testing fixture further includes a fixing member connected to the fixture cover plate and used to fix the buffer assembly on the fixture cover plate, wherein at least one end of the fixing member abuts against the pressure block.

[0012] In one embodiment, the device further includes an elastic pad disposed within the limiting cavity, the pad at least partially passing through the product mounting base and abutting against the camera under test, for providing flexible support when the camera under test is connected to the connecting pin socket.

[0013] In one embodiment, the connector includes a first seat disposed on the fixture cover and a second seat for connecting to an interface of the camera under test, wherein the first seat is at least partially connected to the second seat through the fixture cover.

[0014] In one embodiment, the first base includes a plurality of first pins, the second base includes a plurality of second pins, the plurality of first pins are electrically connected to the adapter board, and the plurality of second pins are electrically connected to the camera under test.

[0015] In one embodiment, the first base has a plug portion for electrical connection with the second base, and the second base has a slot into which the plug portion can be inserted.

[0016] This utility model also provides a camera testing device, including a detection component for acquiring performance parameters of the camera under test, a connector, and the aforementioned camera testing fixture. The detection component is electrically connected to the adapter plate of the camera testing fixture via the connector.

[0017] This invention provides a camera testing fixture that simplifies the signal transmission path by using a connecting pin socket that passes through the fixture cover. This allows the signal to be directly transmitted from the interface of the camera under test to an adapter board, and then from the adapter board to the testing component. Compared to existing signal transmission methods that require multiple transfers, this invention only requires one transfer, effectively avoiding signal attenuation and delay issues, and improving the speed and quality of signal transmission. It is particularly suitable for high-speed data testing scenarios. Furthermore, the detachable connection between the fixture cover and the base facilitates the quick installation and replacement of the camera under test, simplifying the operation process and improving production efficiency.

[0027] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] The terms “upper,” “lower,” “left,” “right,” “front,” “back,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.

[0031] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0032] Please refer to Figures 1 to 2 This utility model provides a camera testing fixture for connecting a camera to be tested to a testing component 7. The testing fixture includes a fixture cover plate 1, a fixture base 2, a product mounting base 3, a connecting pin seat 5, and an adapter plate 4. The fixture cover plate 1 and the fixture base 2 are detachably connected, facilitating quick installation and replacement of the camera to be tested. The product mounting base 3 is located at the end of the fixture base 2 near the fixture cover plate 1, used to fix the camera to be tested, preventing positional displacement during testing and reducing errors.

[0033] Furthermore, one end of the connecting pin socket 5 passes through the fixture cover plate 1 and is electrically connected to the interface of the camera under test, while the other end is electrically connected to the adapter plate 4. The adapter plate 4 is mounted on the end of the fixture cover plate 1 furthest from the product mounting base 3 and is electrically connected to the detection component 7. This allows the signal to be directly transmitted from the interface of the camera under test to the adapter plate 4 via the connecting pin socket 5, and then to the detection component 7 via the adapter plate 4, simplifying the signal transmission path. Compared to the prior art, where the interface of the camera under test needs to be connected to the adapter plate 4 via the connecting pin socket 5, then connected to the fixture base 2 via a set of adapter pins, and finally connected to the detection component 7 via the fixture base 2 and the connector 6, in this embodiment, the interface of the camera under test only needs to be connected to the adapter plate 4 via the connecting pin socket 5, and then directly connected to the detection component 7 via the connector 6. Signal transmission can be completed with only one adapter, effectively avoiding signal attenuation and delay problems, improving the speed and quality of signal transmission, and is particularly suitable for high-speed data testing scenarios.

[0034] Furthermore, a limiting cavity 21 is provided at one end of the fixture base 2 near the fixture cover plate 1, and the product mounting seat 3 is embedded in the limiting cavity 21. Its structural design can ensure the stability of the product mounting seat 3 and prevent it from shifting during the test, thereby further ensuring the fixation effect of the camera under test and reducing the error in the test.

[0035] In the above embodiments, although the limiting cavity 21 limits the product mounting base 3, preventing displacement of the camera under test, the camera is not completely axially constrained within the mounting area, and there is still a possibility that it may move towards the fixture cover plate 1. To solve this problem, such as... Figure 3 As shown, in this embodiment, the camera test fixture also includes an elastic buffer component 11. A mounting groove is formed on the fixture cover plate 1, and at least a portion of the buffer component 11 is embedded in the mounting groove, allowing one end of the buffer component 11 to press against the camera under test mounted on the product mounting base 3 during testing. The elastic pressure applied by the buffer component 11 effectively prevents the camera under test from shifting towards the fixture cover plate 1 during testing, thereby further improving the camera's stability. Simultaneously, because the buffer component 11 is made of elastic material, it will not damage the surface or interface of the camera under test when pressing against it, ensuring the integrity and reliability of the camera and guaranteeing its quality.

[0036] Because cameras are easily affected by dust and other debris during testing, potentially leading to inaccurate test results, and the larger the gap between fixture cover 1 and fixture base 2, the higher the possibility of debris entering, in order to minimize the gap between the cover and the base, such as Figure 4As shown, in this embodiment, the buffer assembly 11 includes a pressure block 110, with mounting flanges 111 at both ends of the pressure block 110. One mounting flange 111 is snapped into the side of the fixture cover plate 1 away from the fixture base 2, and the other mounting flange 111 is snapped into the mounting groove, thereby mounting the buffer assembly 11 onto the fixture cover plate 1. The pressure block 110 is disposed in the mounting groove of the fixture cover plate 1, and a receiving groove 112 is provided at its end near the product mounting seat 3. During the test, the receiving groove 112 can fit tightly against the contact area of ​​the camera under test, thereby reducing the excess gap between the fixture cover plate 1 and the fixture base 2, effectively preventing dust and other debris from entering the fixture, and ensuring the reliability of the test results.

[0037] Furthermore, to prevent the buffer assembly 11 from dislodging due to the top pressure from the camera under test during improper installation, such as... Figure 4 As shown, a fixing member 12 is provided on the fixture cover plate 1, which securely fixes the buffer assembly 11 to the fixture cover plate 1. One end of the fixing member 12 abuts against the pressure block 110. Through direct contact with the pressure block 110, the fixing member 12 can effectively limit the movement range of the buffer assembly 11. Even when subjected to the top pressure of the camera under test during installation or testing, it can ensure that the buffer assembly 11 remains in the correct position, thereby preventing the buffer assembly 11 from falling out of the mounting slot.

[0038] To prevent damage to the camera under test due to contact pressure or vibration when connecting it to connector pin 5, such as Figure 5 As shown, in this embodiment, an elastic pad 22 is provided within the limiting cavity 21. The pad 22 is made of a flexible material (such as silicone, rubber, or foam) and at least partially passes through the product mounting base 3, allowing its upper surface to directly contact the bottom of the camera under test. When the camera under test is connected to the connecting pin socket 5, the pad 22 provides a flexible support structure, effectively alleviating the mechanical pressure on the camera during installation due to contact with the pin socket.

[0039] Specifically, when the camera under test is installed on the product mounting base 3, the pad 22 is slightly compressed under the force of the connecting pin seat 5, forming a flexible support. This compression not only absorbs and disperses pressure, but also improves the stability of the camera under test, preventing shaking during the test.

[0040] like Figure 6 As shown, the connecting pin socket 5 includes a first seat 51 and a second seat 52. The first seat 51 is fixedly mounted on the fixture cover plate 1, and the second seat 52 is used to connect to the interface of the camera to be tested. The first seat 51 passes through the fixture cover plate 1 at least partially and is detachably connected to the second seat 52.

[0041] During installation, the product to be tested is first fixed onto the product mounting base 3. At this point, the first mounting body 51 can be connected to the interface of the product to be tested. Then, the fixture cover plate 1 and fixture base 2 are fastened together. This process does not require worrying about avoiding the position of the connecting pin seat 5, thus avoiding operational difficulties caused by interference from the connecting pin seat 5 in existing technical structures. After the fixture cover plate 1 and base are fastened together, the second mounting body 52 is easily connected from the outside to the part of the first mounting body 51 that penetrates the fixture cover plate 1 via a plug-in connection, thus completing the final electrical connection. Through this segmented connection method, the entire installation process is broken down into two independent steps, which reduces the requirements for initial alignment accuracy and facilitates subsequent adjustment of the pin seat, achieving a fast, accurate, and unobstructed connection operation.

[0042] Specifically, the first base 51 includes multiple first pins, and the second base 52 includes multiple second pins. The multiple first pins are electrically connected to the adapter board 4, and the multiple second pins are electrically connected to the camera under test. When the second base 52 is inserted into the first base 51, the multiple first pins and the multiple second pins are connected to each other to form a complete signal transmission path.

[0043] In this embodiment, to achieve a reliable electrical connection between the first base 51 and the second base 52, the first base 51 is provided with a plug portion 511 for insertion into the second base 52, and the second base 52 is provided with a slot 521 structure that matches the plug portion 511. Specifically, the plug portion 511 of the first base 51 is a slender conductive pin, and its outer surface is covered with a highly conductive material to achieve efficient electrical contact with the second base 52. The shape of the plug portion 511 can be designed as a cylindrical or rectangular cross-section to fit tightly with the slot 521 of the second base 52. The slot 521 of the second base 52 is located at the end where the camera under test is connected. The size and shape of the slot 521 are adapted to the plug portion 511, and its inner surface is also covered with a conductive material. The slot 521 is equipped with an elastic clamping device (such as a conductive spring or a tab) to provide a certain clamping force after the insertion part 511 is inserted, to ensure the stability of the connection and prevent loosening or poor contact caused by vibration or operation during the test.

[0044] During installation, once the fixture cover plate 1 is fastened to the base, the operator only needs to align the slot 521 of the second base 52 with the insertion part 511 of the first base 51 and gently insert it. The elastic clamping device in the slot 521 will automatically lock the insertion part 511, achieving a fast and reliable electrical connection.

[0045] This utility model embodiment also provides a camera testing device, including a detection component 7, a connector 6 and the aforementioned camera testing fixture. One end of the connector 6 is electrically connected to the detection component 7, and the other end of the connector 6 is electrically connected to the adapter plate 4 of the camera testing fixture, thereby electrically connecting the camera to be tested to the detection component 7.

[0046] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
