[0030] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0031] An embodiment of the utility model provides an interface plug strength test fixture, including a clamping assembly and a test assembly; the clamping assembly is used to fix the product to be tested, and the test assembly is used to press on the plug of the product to be tested in an automated manner, wherein the clamping assembly includes a rotating structure that can drive the product to be tested and the plug to rotate synchronously, thereby realizing testing of multiple surfaces of the plug.

[0032] The following is a detailed description of the components of the interface plug strength test fixture provided by the embodiment of the utility model, the positional relationship and the connection relationship between the components in conjunction with the accompanying drawings.

[0033] like Figures 1 to 6 As shown, in the embodiment of the utility model, the clamping assembly 1 includes a fixed clamp 11 and a rotating structure 12, the fixed clamp 11 is used to clamp the product to be tested 4, the rotating structure 12 is connected to the fixed clamp 11, and the rotating structure 12 is used to drive the fixed clamp 11 to rotate along a set angle to adjust the angle of the plug 5 on the product to be tested 4; when the interface plug strength is tested, it is necessary to apply pressure to different sides of the plug 5. The test fixture provided by the utility model adopts automated testing, wherein the flipping of the product to be tested 4 and the plug 5 is completed by automated operation of the rotating structure 12.

[0034] For example, the fixing clamp 11 includes a carrier plate 111 and a pressing member 112, the carrier plate 111 includes a bearing surface, the product to be tested 4 is arranged on the bearing surface, a blocking member is arranged at the edge of the bearing surface, and the blocking member is used to block the edge of the product to be tested 4 to play a role of limiting, or, for example, a soft layer such as rubber material is arranged on the surface of the bearing surface and the blocking member to prevent the carrier plate 111 from scratching the product to be tested 4. The pressing member 112 is located above the product to be tested 4 and is used to press the product to be tested 4 onto the carrier plate 111. For the specific structure of the pressing member 112, refer to the following description.

[0035] For example, the rotating structure 12 includes a driving motor 121; the output shaft of the driving motor 121 is connected to one end of the carrier 111, so that the carrier 111 and the output shaft of the driving motor 121 rotate synchronously. After completing the inspection of one side of the plug 5, the angle between the product to be tested 4 and the plug 5 is adjusted by the rotating structure 12 so that the other side of the plug 5 is in a state to be inspected, and then the inspection of the other side of the plug 5 is completed in cooperation with the test component 2.

[0036] Taking the laptop computer test as an example, the plug 5 is plugged into the socket at the side end. During the test, the four sides of the plug 5 need to be tested, namely the front side, the back side and the two side sides of the plug 5. After completing the test of one side, the driving motor 121 is used to rotate 90 degrees, driving the carrier 111, the product to be tested 4 and the plug 5 to rotate 90 degrees synchronously until the strength test of multiple sides of the plug 5 is completed.

[0037] Continue to refer Figures 1 to 6 As shown, in the embodiment of the utility model, the test assembly 2 includes a movable structure 21, a test sensor 22 and a test head 23. One end of the test sensor 22 is connected to the test head 23, and the other end is connected to the movable structure 21. The test head 23 is adjusted by the movable structure 21 to press the plug 5.

[0038] When the plug 5 rotates to different angles, the relative position between it and the test assembly 2 will change, and the position of the test head 23 is changed by the mobile structure 21, and the pressing operation on the plug 5 is realized. After the test head 23 is pressed on the plug 5, the test sensor 22 can obtain the current pressure value of the test head 23, and the pressure value is transmitted to the control device. If the current pressure value meets the set value range, the control device controls the mobile structure 21 to stop moving and maintain the current state. The above steps are repeated periodically to realize the test of one side of multiple plugs 5.

[0039] Then, the rotating structure 12 adjusts the positions of the product to be tested 4 and the plug 5, and the test assembly 2 completes the current test again until the tests on multiple surfaces are completed.

[0040] For example, the rotating structure 12 also includes a fork arm 122, which includes a vertical portion 1221, a first horizontal portion 1222 and a second horizontal portion 1223. The first horizontal portion 1222 and the second horizontal portion 1223 are located on the same side of the vertical portion 1221 and are fixedly connected to the vertical portion 1221 respectively; the output shaft of the driving motor 121 is vertically connected to a side of the vertical portion 1221 away from the first horizontal portion 1222 and the second horizontal portion 1223, the first horizontal portion 1222 is connected to the carrier plate 111, the second horizontal portion 1223 extends to above the product to be tested 4, and a clamping member 112 is provided on the second horizontal portion 1223.

[0041] In the rotating structure 12, the first horizontal portion 1222 and the second horizontal portion 1223 of the fork arm 122 provide stable support for the carrier plate 111 and the clamping member 112 respectively, making the adjustment more convenient when the angle is adjusted, and the support of the fork arm 122 structure is more stable, thereby improving the accuracy of the test.

[0042] In the embodiment of the utility model, the mobile structure 21 includes a multi-dimensional mobile module 211, and the test sensor 22 is connected to the multi-dimensional mobile module 211, and the position of the test head 23 is adjusted by the multi-dimensional mobile module 211. For example, the multi-dimensional mobile module 211 is a three-dimensional mobile module, which is an X-direction mobile module, a Y-direction mobile module, and a Z-direction mobile module. By setting the three-dimensional mobile module, the freedom of movement of the test head 23 can be improved, and the test head 23 can be moved to a specified position faster and more accurately.

[0043] For example, the X-axis moving module, the Y-axis moving module and the Z-axis moving module are linear screw modules.

[0044] In the embodiment of the utility model, the test head 23 includes an abutment terminal 231, and the abutment terminal 231 is detachably connected to the test sensor 22. The detachable connection method is adopted so that the abutment terminal 231 can be replaced. When testing different structures such as the plug 5, the abutment terminal 231 of the corresponding size can be replaced. For example, a screw rod 232 is provided on the abutment terminal 231, and the screw rod 232 is screwed to the test sensor 22. In this way, not only can the abutment terminal 231 be replaced, but also the relative position between the abutment terminal 231 and the test sensor 22 can be adjusted by rotating the screw rod 232.

[0045] For example, the clamping member 112 includes a pressing portion 1121 and a clamping screw 1122; the clamping screw 1122 is threadedly connected to the second horizontal portion 1223, and the axis of the clamping screw 1122 is perpendicular to the surface where the product to be tested 4 is located, the pressing portion 1121 is located between the second horizontal portion 1223 and the product to be tested 4, and is connected to one end of the clamping screw 1122; the pressure applied by the pressing portion 1121 to the product to be tested 4 is adjusted by rotating the clamping screw 1122.

[0046] A wrench is provided on the clamping screw 1122, and the clamping screw 1122 is rotated by turning the wrench. During the rotation of the clamping screw 1122, the pressing portion 1121 moves downward to gradually press the product 4 to be tested. Among them, the pressing portion 1121 has a certain pressing area, which can apply a more stable pressing to the product 4 to be tested. For example, the pressing portion 1121 includes a central portion 11211 and a plurality of pressing rods 11212, and the plurality of pressing rods 11212 are arranged in a divergent shape with the central portion 11211 as the center; a pressing end 11213 is provided at one end of the pressing rod 11212 away from the central portion 11211. For example, a soft material, such as a rubber material, is provided on the pressing end 11213, thereby preventing the pressing end 11213 from scratching the product 4 to be tested.

[0047] For example, a universal head 1123 is provided at the connection end of the clamping screw 1122 and the pressing portion 1121, and the clamping screw 1122 is connected to the central portion 11211 through the universal head 1123. By providing the universal head 1123, the relative position between the pressing portion 1121 and the clamping screw 1122 can be fine-tuned. When the surface of the product 4 to be tested pressed by the pressing end head 11213 changes, the position can be fine-tuned through the universal head 1123, thereby ensuring that the pressing rod 11212 is adapted to the current product 4 to be tested.

[0048] Continue to refer Figures 1 to 6 As shown, the interface plug strength test fixture also includes a base 3, and the clamping component 1 and the test component 2 are arranged on the base 3. Above the base 3 is a control space, and the clamping component 1 and the test component 2 are centrally arranged in the control space, so that the fixture forms an integral structure.

[0049] For example, a groove-shaped structure is arranged above the base 3, and the driving motor 121 of the clamping assembly 1 is arranged on a side wall of the groove-shaped structure, and the rotation of the fixed clamp 11 is controlled by the driving motor 121; the X-axis moving module or the Y-axis moving module of the multi-dimensional moving module 211 is arranged at the top of a group of side walls of the groove-shaped structure.

[0050] In the embodiment of the utility model, the base 3 includes a control panel 31, and the control panel 31 includes a control button 32 for controlling the clamping assembly 1 and / or the test assembly 2. A control device is included inside the base 3, and the control device is connected to the control panel. For example, the control button 32 includes a start-stop switch, a rotation button of the drive motor 121, a mobile module of the multi-dimensional mobile module 211, etc.

[0051] The utility model provides an interface plug strength test fixture. During the test operation, the product to be tested 4 is fixed by the clamping component 1, and the plug 5 is plugged into the interface of the product to be tested 4. The test head 23 is moved and pressed on the plug 5 by the moving structure 21. At this time, the test sensor 22 obtains the pressure of the test head 23. When the pressure value reaches the set value or the set range, the moving structure 21 stops, and after maintaining the current pressure setting time, a test is completed. Among them, one side of the plug 5 needs to be tested multiple times. After completing the test operation of one side of the plug 5, the clamping component 1 drives the product to be tested 4 and the plug 5 to rotate, and the test component 2 is used to test the other side of the plug 5. Repeat the above steps to complete the testing of multiple sides of the plug 5.

[0052] The technical solution of the utility model adopts automated testing. During the test, the test pressure is constant, the test accuracy is higher, the test time is shorter, the efficiency is higher, and during the test, no manual operation is required, which is safer.
