Description

Technical Field

[0001] This invention relates to the field of electronic product testing technology, and in particular to a clamping device and a method of using the clamping device. Background Technology

[0002] When testing electronic products, the device under test (DUT) needs to be fixed in place to maintain a stable connection with the test connector. However, when the surface of the DUT is concave and the test connector needs to contact the DUT on the concave surface, the test connector needs to be designed with a matching convex shape. The convex connector head is prone to collision with the DUT during assembly, which can damage the test connector itself or scratch the appearance of the DUT. Over time, this will affect the lifespan of both the DUT and the test connector.

[0003] Therefore, it is urgent to design a clamping device to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping device and a method for using the clamping device, which can avoid friction and collision between the connector head of the test connector and the test object during the testing process, thereby protecting the test object and the test connector.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The clamping device includes:

[0007] A support assembly includes a support member, an elastic member, and a base plate. The elastic member is disposed between the base plate and the support member. The support member has a support surface on its side opposite to the base plate, and a connecting hole is formed on the support surface. The support member is movable relative to the base plate in a first direction between a test position and a disengagement position. The elastic member is configured to drive the support member to stop in the disengagement position. A test connector is located between the support member and the base plate. When the support member is in the test position, the connector head of the test connector extends out of the support surface through the connecting hole. When the support member is in the disengagement position, the connector head of the test connector is located between the support surface and the base plate.

[0008] A pressure plate, which is used to press against the object to be tested placed on the support member along a first direction.

[0009] Preferably, the clamping device further includes a mounting frame, on which both the base plate and the pressure plate are mounted.

[0010] Preferably, the mounting frame includes a frame body and a cover rotatably connected to the frame body, a base plate is disposed on the frame body, and a pressure plate is disposed on the cover. When the cover rotates, it can drive the pressure plate to press against the object to be tested.

[0011] Preferably, the pressure cap has a rotating end and a snap-fit ​​end. The rotating end is hinged to the frame. The snap-fit ​​end and the frame are provided with a slot on one side and a buckle on the other side, and the buckle is snapped in the slot.

[0012] Preferably, the mounting bracket further includes a limiting block disposed on the bracket body, and the support member has a guide groove that matches the limiting block. The guide groove extends along the first direction, and the limiting block is engaged in the guide groove.

[0013] Preferably, the support member is provided with a stop portion, and the limiting block is sandwiched between the bottom of the guide groove and the stop portion in the first direction.

[0014] Preferably, the support surface is recessed on the support member.

[0015] Preferably, the surface of the pressure plate that is in contact with the object to be tested is the pressure surface, and the pressure surface is recessed on the pressure plate;

[0016] A clamping cavity for accommodating the object to be tested is formed between the pressing surface and the supporting surface.

[0017] Preferably, the support member has a surrounding plate extending in a first direction, the surrounding plate being used to enclose the test connector.

[0018] The clamping device is used in the following steps:

[0019] S1. Place the object to be tested on the support surface of the support member in the disengaged position, adjust the position of the object to be tested so that the connection port of the object to be tested is aligned with the connection hole, place the test connector between the support member and the base plate, and adjust the test connector so that the connector head of the test connector is aligned with the connection hole.

[0020] S2. The pressure plate is used to press the object to be tested along the first direction. The support member moves to the test position under pressure. The connector head of the test connector passes through the connection hole and connects to the connection port of the object to be tested.

[0021] S3. Perform a connection test;

[0022] S4. After the test is completed, the pressure plate is removed from the test object. The support member automatically returns to the disengaged position under the elastic force of the elastic member, and then the test object is removed.

[0023] The beneficial effects of this invention are as follows:

[0024] The clamping device provided by this invention has a support surface of a support member used to abut against the object to be tested, thereby supporting the object. Since the pressure plate can press against the object to be tested on the support member in a first direction, the object to be tested is clamped and fixed under the cooperation of the support member and the pressure plate to ensure the stability of the object to be tested during the test. The support member has a disengagement position. When not being tested, the support member stops at the disengagement position by moving away from the base plate in the first direction under the elastic force of the elastic member. Since the connector head of the test connector is located between the support surface and the base plate and does not protrude from the support surface at this time, when the object to be tested is placed on the support surface, it will not come into contact with the connector head of the test connector, thereby avoiding collision or scratching between the object to be tested and the test connector. After the object to be tested is placed on the support member, the pressure plate is used to press against the object to be tested in the first direction. Under the pressure of the object to be tested, the support member will move closer to the base plate in the first direction to reach the test position. Since a connection hole is provided on the support surface, the connector head of the test connector will extend out of the support surface through the connection hole, thereby automatically connecting with the object to be tested placed on the support surface. When not testing the object under test, this clamping device can automatically move the support to hide the connector head of the test connector, thus preventing the connector head from colliding and scratching the object under test, and effectively protecting both the test connector and the object under test. During testing, the pressure plate presses against the object under test and simultaneously presses against the support, exposing the connector head of the test connector through the connection hole and allowing it to connect directly to the object under test on the support. The device is simple to operate, requires no additional complex electromagnetic or other control structures, and has good practicality.

[0025] The clamping device and its usage method provided by this invention involves placing the object to be tested on the support surface when the support member is in the disengaged position. At this time, the connector head of the test connector is hidden below the support surface, thereby avoiding friction and collision between the object to be tested and the connector head, effectively protecting both the connector head and the object to be tested. After the object to be tested is placed, a pressure plate is used to press against the object to be tested along a first direction, and the support member will move to the test position. During this process, the connector head of the test connector will automatically connect to the connection port of the object to be tested through the connection hole. The steps are simple and the operation is convenient. During the test, this clamping device and its usage method can effectively prevent accidental friction and collision between the object to be tested and the connector head of the test connector, thus protecting both the object to be tested and the test connector, and has good practicality.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] like Figure 1 and Figure 2As shown, the present invention provides a clamping device, which includes a support assembly 1 and a pressure plate 2. The support assembly 1 includes a support member 11, an elastic member 12, and a base plate 13. The elastic member 12 is disposed between the base plate 13 and the support member 11. The support member 11 has a support surface 111 on the side opposite to the base plate 13. A connecting hole 112 is provided on the support surface 111. The support member 11 can move relative to the base plate 13 in a first direction between a test position and a disengagement position. The elastic member 12 is configured to drive the support member 11 to stop in the disengagement position. A test connector 100 is located between the support member 11 and the base plate 13. When the support member 11 is in the test position, the connector head of the test connector 100 extends out of the support surface 111 through the connecting hole 112. When the support member 11 is in the disengagement position, the connector head of the test connector 100 is located between the support surface 111 and the base plate 13. The pressure plate 2 is used to press against the test object placed on the support member 11 in the first direction. In this embodiment, the elastic element 12 is a compression spring, and the support surface 111 of the support element 11 is used to abut against the object to be tested, thereby supporting the object to be tested. Since the pressure plate 2 can press against the object to be tested on the support element 11 in the first direction, the object to be tested is clamped and fixed under the cooperation of the support element 11 and the pressure plate 2 to ensure the stability of the object to be tested during the test. The support element 11 has a disengaged position. When not being tested, the support element 11 moves away from the base plate 13 in the first direction under the elastic force of the elastic element 12 and stops in the disengaged position. Since the connector head of the test connector 100 is located between the support surface 111 and the base plate 13 and does not protrude from the support surface 111 at this time, the test connector 100 is located between the support surface 111 and the base plate 13. The support surface 111 is designed so that when the test object is placed on the support surface 111, it will not come into contact with the connector head of the test connector 100, thereby avoiding collision or scratches between the test object and the test connector 100. After the test object is placed on the support 11, the pressure plate 2 is used to press the test object along the first direction. Under the pressure of the test object, the support 11 will move closer to the base plate 13 along the first direction to reach the test position. Since the support surface 111 has a connection through hole 112, the connector head of the test connector 100 will extend out of the support surface 111 through the connection through hole 112, thereby automatically connecting with the test object placed on the support surface 111. When the object under test is not being tested, the clamping device can move the support member 11 by the elastic force of the elastic member 12 to hide the connector head of the test connector 100, so as to avoid the connector head of the test connector 100 from colliding and scratching with the object under test, thereby effectively protecting the test connector 100 and the object under test. At the same time, when testing, the pressure plate 2 presses against the object under test and presses against the support member 11 to expose the connector head of the test connector 100 through the hole of the connection 112 and directly connect it to the object under test on the support member 11. The operation is simple and does not require additional complex electromagnetic or other control structures, and has good practicality.Specifically, when using the clamping device, the base plate 13, elastic element 12, support element 11 and pressure plate 2 are arranged sequentially from bottom to top along the height direction. That is, the pressure plate 2 presses the object to be tested placed on the lower support element 11 downward along the height direction. The first direction is the downward direction along the height direction, that is, parallel to the pressing direction of the pressure plate 2 on the object to be tested.

[0040] Furthermore, such as Figure 1 As shown, the clamping device also includes a mounting frame 3, on which both the base plate 13 and the pressure plate 2 are mounted. In this embodiment, both the base plate 13 and the pressure plate 2 are mounted on the mounting frame 3, thereby connecting the supporting component 1 and the pressure plate 2 into an integrated structure via the mounting frame 3, which facilitates handling.

[0041] Specifically, such as Figure 2 and Figure 3 As shown, the mounting frame 3 includes a frame body 31 and a pressure plate 32 rotatably connected to the frame body 31. A base plate 13 is disposed on the frame body 31, and a pressure plate 2 is disposed on the pressure plate 32. When the pressure plate 32 rotates, it can drive the pressure plate 2 to press against the object to be tested. In this embodiment, the pressure plate 32 is rotatably disposed on the top of the frame body 31, and the pressure plate 2 is connected to the pressure plate 32 by bolts. When the pressure plate 32 is rotated, the pressure plate 32 drives the pressure plate 2 to rotate synchronously, and the pressure plate 2 presses against the object to be tested on the support member 11 downward in the first direction.

[0042] Specifically, such as Figure 1 and Figure 3 As shown, the pressure cap 32 has a rotating end and a snap-fit ​​end. The rotating end is hinged to the frame 31. Both the snap-fit ​​end and the frame 31 have a slot on one side and a buckle 33 on the other, with the buckle 33 snapping into the slot. In this embodiment, the frame 31 has a buckle 33, and the snap-fit ​​end has a slot that matches the buckle 33. When the pressure cap 32 rotates, moving the support member 11 to the test position, the slot engages with the buckle 33, thus keeping the support member 11 in the test position. This ensures that the pressure plate 2 can stably press against the object under test, preventing the connector head of the test connector 100 from disconnecting from the object under test during the test.

[0043] Specifically, such as Figure 2 and Figure 3As shown, the mounting frame 3 also includes a limiting block 34, which is disposed on the frame body 31. A guide groove 113 matching the limiting block 34 is provided on the support member 11. The guide groove 113 extends along a first direction, and the limiting block 34 is engaged in the guide groove 113. In this embodiment, guide grooves 113 are provided on both sides of the support member 11. A limiting block 34 is provided on the mounting frame 3 corresponding to the guide groove 113. The limiting block 34 is engaged in the guide groove 113, matching it. The limiting block 34 can slide along the first direction in the guide groove 113, thereby ensuring the stability and accuracy of the support member 11's movement between the test position and the disengagement position.

[0044] Specifically, such as Figure 2 As shown, the support member 11 is provided with a stop portion 114, and the limiting block 34 is sandwiched between the bottom of the guide groove 113 and the stop portion 114 in the first direction. In this embodiment, the stop portion 114 is provided on the support member 11, and the stop portion 114 can abut against the limiting block 34 in the first direction. Therefore, the stop portion 114 can limit the limiting block 34, so that the limiting block 34 can only slide between the bottom of the guide groove 113 and the stop portion 114, preventing the support member 11 located at the disengagement position from falling off the mounting bracket 3.

[0045] Furthermore, such as Figure 2 The support surface 111 is recessed on the support member 11. In this embodiment, the support surface 111 is recessed on the support member 11, and the support surface 111 is in contact with the lower surface of the object to be tested, so that the object to be tested can be pressed more stably against the support member 11.

[0046] Specifically, such as Figure 3 and Figure 4 As shown, the surface of the pressure plate 2 that is in contact with the object to be tested is the pressure surface 21, which is recessed in the pressure plate 2. A clamping cavity for accommodating the object to be tested is formed between the pressure surface 21 and the support surface 111. In this embodiment, opposite to the support surface 111, the pressure plate 2 is also recessed with a pressure surface 21, which is in contact with the upper surface of the object to be tested. A clamping cavity for accommodating the object to be tested and matching the object to be tested can be formed between the pressure surface 21 and the support surface 111, thereby further improving the clamping stability of the clamping device for the object to be tested.

[0047] Furthermore, such as Figure 2 and Figure 4As shown, the support member 11 has a surrounding plate 115 extending along a first direction, which is used to enclose the test connector 100. In this embodiment, the surrounding plate 115 extends along the first direction on all four sides of the support member 11. The test connector 100 is disposed on the base plate 13. When the support member 11 is in the disengaged position, the connector head of the test connector 100 is located below the support surface 111. The surrounding plate 115 encloses the connector head between the support member 11 and the base plate 13 to protect the connector head from contamination by external debris.

[0048] This embodiment also provides a method for using the clamping device, which includes the following steps:

[0049] S1. Place the object to be tested on the support surface 111 of the support member 11 in the disengaged position, adjust the position of the object to be tested so that the connection port of the object to be tested is aligned with the connection hole 112, place the test connector 100 between the support member 11 and the base plate 13, and adjust the test connector 100 so that the connector head of the test connector 100 is aligned with the connection hole 112. In this embodiment, before using the clamping device to test the object to be tested, the object to be tested is placed on the support surface 111, and the test connector 100 is provided between the support member 11 and the base plate 13.

[0050] S2. The pressure plate 2 is used to press against the test object along the first direction. Under the pressure, the support member 11 moves to the test position, and the connector head of the test connector 100 passes through the connection hole 112 and connects to the connection port of the test object. In this embodiment, the pressure plate 2 is used to press against the test object along the first direction. Under the pressure of the test object, the support member 11 moves to the test position along the first direction, and the connector head of the test connector 100 passes through the connection hole 112 and connects to the connection port of the test object.

[0051] S3. Perform a connection test.

[0052] S4. After the test is completed, the pressure plate 2 is removed from the test object. The support member 11 automatically resets to the disengaged position under the elastic force of the elastic member 12, and then the test object is removed. In this embodiment, after the test is completed, the pressure plate 2 is removed from the test object. The test object and the support member 11 will move upward in the first direction to the disengaged position under the elastic force of the lower elastic member 12. At this time, the connector head of the test connector 100 is located below the support surface 111, which facilitates the removal of the test object from the support member 11.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
