[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-5 Specific embodiments of this utility model will be described in detail.

[0035] In this utility model, the terms "connection" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure.

[0036] In this utility model, terms such as "inner", "upper", and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, 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.

[0037] This utility model embodiment provides a plug-in / plug-out testing fixture, see attached drawing. Figure 1 and Figure 2 The insertion / removal test fixture includes a base 10 and a test device 20. The base 10 has a support portion 110 for placing the product under test; for example, such as Figure 1 and Figure 2As shown, the testing device 20 includes a test drive assembly 210, a pressure sensor 230, and a buffer assembly 240 connected in sequence. A test movable block 30 is fixedly mounted on the end of the buffer assembly 240 away from the pressure sensor 230. Alternatively, the testing device 20 may include a test drive assembly 210, a buffer assembly 240, and a pressure sensor 230 connected in sequence. A test movable block 30 is fixedly mounted on the end of the pressure sensor 230 away from the buffer assembly 240. The test drive assembly 210 is mounted on the base 10. The testing device is configured such that if the product under test is fixed to the support portion 110, the test drive assembly 210 drives the test movable block 30 to insert or remove it from the product under test to perform an insertion / removal test. The pressure sensor 230 is used to detect the insertion / removal force between the test movable block 30 and the product under test.

[0038] During the manufacturing process of a charger, the plug-in structure needs to be tested for insertion and removal to ensure a stable connection between the charger and the socket or electronic device's connection cable. Therefore, this utility model provides a plug-in testing fixture that, firstly, improves testing efficiency and reduces labor intensity compared to manual plug-in testing, by automatically performing the test on the charger using this fixture; secondly, by using a pressure sensor 230, the insertion and removal force between the test block 30 and the charger is detected; thirdly, by using a buffer component 240, the test block 30 is inserted into the charger's plug-in structure, providing cushioning to reduce the impact force between the test block 30 and the charger's plug-in structure, thus reducing or even preventing damage to the charger's plug-in structure during testing; furthermore, the compressed buffer component 240 can apply an elastic force to the charger's plug-in structure, ensuring the test block 30 is firmly inserted into the plug-in structure and providing a corrective effect.

[0039] In this embodiment of the invention, there are at least two test movable blocks 30; for example, there can be two, three, or other numbers of test movable blocks. There are at least two test devices 20; for example, there can be two, three, or other numbers of test devices, spaced apart and matching the number of test movable blocks 30. The test devices 20 are used to drive the corresponding test movable blocks 30 to perform insertion and removal tests on different positions of the product under test. It should be noted that different positions refer to adjacent or opposite surfaces of the product under test. This embodiment of the invention provides a insertion and removal testing fixture that, by setting at least two test devices 20 and at least two test movable blocks 30, can simultaneously perform insertion and removal tests on different positions of the charger, thereby improving the insertion and removal testing efficiency of the charger.

[0040] In this embodiment of the utility model, see appendix. Figures 1-4The test movable block 30 includes a first test movable block 310 and a second test movable block 320; the test device 20 includes a first test device 201 and a second test device 202. The first test device 201 includes a test drive assembly 210, a pressure sensor 230, and a buffer assembly 240 connected in sequence. One end of the buffer assembly 240 away from the pressure sensor 230 is fixed to the first test movable block 310. The test drive assembly 210 is mounted on the base 10 and is used to drive the first test movable block 310 to insert or remove it from the product under test along a first direction for insertion / removal testing. The second test device 202 includes a test drive assembly 210, a pressure sensor 230, and a buffer assembly 240 connected in sequence. One end of the buffer assembly 240 away from the pressure sensor 230 is fixed to the second test movable block 320. The test drive assembly 210 is mounted on the base 10 and is used to drive the second test movable block 320 to insert or remove it from the product under test along a third direction for insertion / removal testing. The third direction is perpendicular to the first direction. For example, ... Figure 1 As shown, the first direction is the X direction, and the third direction is the Z direction.

[0041] In this embodiment of the invention, the product under test has at least two spaced-apart plug-in structures. Each test movable block 30 has a plug-in portion that can be inserted into or removed from the corresponding plug-in structure. One plug-in portion is a pin, and the corresponding plug-in structure is an interface; the other plug-in portion is a slot, and the corresponding plug-in structure is a plug. For example, see the attached diagram. Figures 1-4 The test active block 30 includes a first test active block 310 and a second test active block 320. The first test active block 310 has a first plug portion 311, which is a pin. The second test active block 320 has a second plug portion 321, which is a slot.

[0042] In this embodiment of the utility model, see appendix. Figures 1-4The testing device 20 also includes a displacement sensor 260, which is installed at the power output end of the test drive assembly 210 and is used to detect the displacement of the test movable block 30 when it is inserted into or removed from the product under test. It should be noted that the test drive assembly 210 moves at a preset test speed from a state where the test movable block 30 is completely separated from the product under test to a state where the test movable block 30 is completely inserted into the product under test. This setup serves two purposes: firstly, by setting up the displacement sensor 260, the displacement of the test movable block 30 when it is inserted into or removed from the charger's plug-in structure can be recorded, which can be used to determine whether the length or depth of the charger's plug-in structure meets the preset size standard; secondly, by setting up the displacement sensor 260 and the pressure sensor 230, the two work together to accurately obtain the dynamic changes in insertion force and displacement during the insertion process, improving the comprehensiveness and accuracy of the insertion and removal test; furthermore, by setting up the displacement sensor 260 and the pressure sensor 230, based on the displacement data and insertion force data, the energy loss and friction coefficient during the insertion and removal process of the test movable block 30 and the charger can be further calculated, providing a quantitative basis for optimizing the charger design.

[0043] In this embodiment of the utility model, the type of displacement sensor 260 is not limited; it can be either a contact type or a non-contact type, as detailed below: For example, Figure 2 As shown, displacement sensor 260 is a contact displacement sensor, which is installed at the power output end of test drive assembly 210. The probe of the contact displacement sensor abuts against the end of test movable block 30 near buffer assembly 240. Alternatively, displacement sensor 260 may be a laser displacement sensor (not shown in the figure).

[0044] In this embodiment of the utility model, see appendix. Figure 3 and Figure 4 The power output end of the test drive component 210 is fixed with a movable base 220, and the displacement sensor 260 is installed on the movable base 220.

[0045] In this embodiment of the utility model, see appendix. Figure 3 and Figure 4 The buffer assembly 240 includes a buffer connecting plate 241, a guide post 242, and a spring 243. The buffer connecting plate 241 is fixed to the end of the pressure sensor 230 away from the test drive assembly 210. One of the buffer connecting plate 241 and the test movable block 30 has a guide hole (not shown in the figure), the guide post 242 is slidably connected to the guide hole, and the end of the guide post 242 is fixed to the other. The spring 243 is disposed between the buffer connecting plate 241 and the test movable block 30. For example, as... Figure 3 and Figure 4As shown, the buffer connecting plate 241 has a guide hole, and the guide post 242 is slidably connected to the guide hole, with the end of the guide post 242 fixed to the test movable block 30; or, for example, the test movable block 30 has a guide hole, the guide post 242 is slidably connected to the guide hole, and the end of the guide post 242 is fixed to the buffer connecting plate 241. It should be noted that if the test movable block 30 is fully inserted into the insertion structure of the product under test, the spring 243 is compressed, and the spring 243 at this time has a tendency to drive the insertion part of the test movable block 30 to move along the depth direction of the insertion structure of the product under test. With this configuration, the guide post 242 provides guidance for the movement of the test movable block 30, and the spring 243 provides buffering for the charger insertion test, avoiding hard contact between the insertion part of the test movable block 30 and the charger insertion structure, reducing or even preventing damage to the charger insertion structure during testing.

[0046] In this embodiment of the invention, the location of the spring 243 is not limited, as detailed below:

[0047] For example, such as Figure 3 and Figure 4 As shown, spring 243 is sleeved on guide post 242; for example, at least one of buffer connecting plate 241 and test movable block 30 is provided with spring receiving groove, and spring 243 is provided in spring receiving groove.

[0048] In this embodiment of the invention, a movable base 220 is fixedly mounted on the power output end of the test drive assembly 210, and one of the pressure sensor 230 and the buffer assembly 240 is fixedly mounted on the movable base 220; for example, Figures 2-4 As shown, the movable base 220, pressure sensor 230, and buffer assembly 240 are connected in sequence; or, for example, the movable base 220, buffer assembly 240, and pressure sensor 230 are connected in sequence; the testing device 20 also includes a guide rail 250, which is mounted on the movable base 220, and the test movable block 30 is slidably connected to the guide rail 250. In this configuration, the guide rail 250 provides guidance for the movement of the test movable block 30.

[0049] In this embodiment of the utility model, the type of the test driver component 210 is not limited, and the specific implementation is as follows: In one embodiment, such as... Figure 3 As shown, the test drive assembly 210 includes a motor 211 and a linear module 212 connected by a drive connection. The motor 211 is mounted on the base 10, and the linear module 212 is connected by a drive connection to a movable base 220. One of the pressure sensor 230 and the buffer assembly 240 is mounted on the movable base 220; for example, as Figure 3 As shown, pressure sensor 230 is mounted on movable base 220; for example, buffer assembly 240 is mounted on movable base 220. In another embodiment, as... Figure 4As shown, the test drive assembly 210 includes a linear drive 213, which is mounted on the base 10 and is drivenly connected to a movable base 220. One of the pressure sensor 230 and the buffer assembly 240 is mounted on the movable base 220. Furthermore, the test drive assembly 210 may also employ other drive structures found in the prior art, which will not be described in detail here.

[0050] In this embodiment of the utility model, see appendix. Figure 2 The bearing portion 110 is provided with a first limiting portion 410 and a second limiting portion 420, which can respectively abut against the first side and the second side of the product to be tested; see appendix. Figure 5 The base 10 is fixedly provided with a first clamping drive assembly 510 and a second clamping drive assembly 530. The first clamping drive assembly 510 is tractively connected to a first clamping part 520, which is used to drive the first clamping part 520 to move closer to or away from the first limiting part 410 along a first direction. The second clamping drive assembly 530 is tractively connected to a second clamping part 540, which is used to drive the second clamping part 540 to move closer to or away from the second limiting part 420 along a second direction. The first direction is perpendicular to the second direction, for example, as shown in the image. Figure 5 As shown, the first direction is the X direction, and the second direction is the Y direction. This setting limits and clamps the charger, ensuring that the charger's position is fixed during plug-in / plug-out tests, thus guaranteeing the smooth conduct of the tests.

[0051] In this embodiment of the utility model, the structures of the first limiting part 410 and the second limiting part 420 are not limited, and are as follows:

[0052] For example, such as Figure 2 As shown, the bearing portion 110 has a receiving groove 111, which has a first side wall and a second side wall adjacent to each other. The first side wall forms a first limiting portion 410, and the second side wall forms a second limiting portion 420.

Figure 5 The base 10 is fixedly provided with a clamping drive 550, which is drivenly connected to a clamping part 560 for driving the clamping part 560 to clamp the edge of the upper surface of the product to be tested along a third direction, for example, as Figure 5 As shown, the third direction is the Z direction. This setting allows the charger to be clamped in three directions, improving the stability of the charger and preventing it from shaking during plug-in / plug-out tests, thus ensuring the smooth conduct of the tests.

[0056] In this embodiment of the utility model, the type of the pressing drive 550 is not limited, and it can be a spinning cylinder, an electric push rod, or a linear cylinder.

[0057] In this embodiment of the invention, the clamping drive member 550 is disposed opposite to one of the first clamping part 520 and the second clamping part 540. This arrangement enables multi-point clamping of the charger, improving the clamping stability of the charger.

[0058] In this embodiment of the invention, the first clamping part 520, the second clamping part 540, and the pressing part 560 are each provided with a flexible structure (not shown in the figure). This arrangement avoids scratching the surface of the product to be tested.

[0059] In this embodiment of the utility model, see appendix. Figure 5 The base 10 includes a bottom plate 120 and a support platform 130 connected to each other. The support platform 130 has a clearance hole 113. A bearing portion 110 is fixed to the support platform 130.

[0060] The first clamping drive assembly 510 includes a first clamping drive member 511, a first clamping connecting plate 512, and a first slide 513 connected in sequence. The first clamping drive member 511 is installed between the support platform 130 and the base plate 120. The upper end of the first clamping connecting plate 512 extends out of the clearance hole 113 and is located in the through groove 112. The first slide 513 is disposed in the through groove 112, and the end of the first slide 513 away from the first clamping connecting plate 512 is connected to the first clamping part 520. It should be noted that the first clamping drive member 511 is an electric push rod or a cylinder.

[0062] In this embodiment of the invention, the bottom surface of the support portion 110 has an opening; the base 10 is provided with a detection component (not shown in the figure) for detecting whether the product to be tested is placed on the support portion 110 through the opening. Specifically, the sensor is a photoelectric sensor or an ultrasonic sensor.

[0063] In this embodiment of the utility model, the insertion and removal test fixture includes a controller, a test drive assembly 210, a pressure sensor 230, a displacement sensor 260, a first clamping drive 511, a second clamping drive 531, a pressing drive 550, and a detection component, all of which are electrically connected to the controller. The controller is configured to: control the first clamping drive 511, the second clamping drive 531, and the pressing drive 550 to clamp the product under test when the detection component detects that the product under test is placed on the support part 110; and control the test drive assembly 210 to drive the test movable block 30 to perform an insertion test on the product under test.

[0064] Taking the application of this insertion / removal testing fixture to a charger as an example, the working principle of the insertion / removal testing fixture provided by this utility model is as follows:

[0065] Place the charger under test in the carrier section 110;

[0066] If the detection component detects the charger under test, it controls the first clamping drive 511 to drive the first clamping part 520 to move along the first direction, and controls the second clamping drive 531 to drive the second clamping part 540 to move along the second direction, so as to bring the first side of the charger under test against the first side wall of the receiving groove 111 and the second side of the charger under test against the second side wall of the receiving groove 111. Then, it controls the pressing drive 550 to drive the pressing part 560 to press against the upper surface of the charger under test along the third direction, thereby achieving clamping of the charger under test in three directions.

[0067] The test drive component 210 of the control first test device 201 drives the first test movable block 310 to insert or pull out of the corresponding position of the plug-in structure of the charger along the first direction, and detects the insertion and extraction force between the first test movable block 310 and the charger based on the pressure sensor 230; and detects the displacement of the first test movable block 310 when it is inserted into or pulled out of the charger based on the displacement sensor 260.
