Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a testing device for equipment plug terminals. Background Technology

[0002] Currently, various electronic devices and chargers require plugs for power connection. After production, plugs need to have an insulating layer installed on their terminals for protection. Before leaving the factory, this insulating layer must undergo an abrasion resistance test to ensure its protective quality. Current testing machines test the abrasion resistance of the terminal insulation layer by repeatedly rubbing it a certain number of times. However, for two-terminal plugs, different sizes and specifications of plugs vary, resulting in different terminal heights when placed on the testing machine. Therefore, current testing machines can only test one type of plug and cannot be adapted to different plug sizes. Utility Model Content

A U-shaped friction steel pin is disposed on the side of the lifting assembly facing the mounting base. A clamping assembly for fixing the plug is disposed on the mounting base. A driver is disposed on the side of the mounting base away from the U-shaped friction steel pin, and the driver is used to drive the mounting base to move closer to or away from the U-shaped friction steel pin.

[0004] Preferably, the lifting assembly includes a base, a support column that is slidably mounted on the base, a connecting block on the top of the support column, and a locking element for locking or releasing the support column on one side of the base.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0016] Example

[0017] To address the aforementioned technical problems, this embodiment provides a device for testing device plug terminals, suitable for testing products with insulated plugs, such as... Figure 1-2As shown, the device includes a machine base 10, a mounting base 20 slidably mounted on the machine base 10, a lifting assembly 30 located on one side of the mounting base 20 on the machine base 10, a U-shaped friction steel needle 40 located on the side of the lifting assembly 30 facing the mounting base 20, a clamping assembly 60 located on the mounting base 20, and a driver 50 located on the side of the mounting base 20 away from the U-shaped friction steel needle 40. After the plug is placed on the mounting base 20, the terminals on the plug face the U-shaped friction steel needle 40. The clamping assembly 60 fixes the plug on the mounting base 20, and then the driver 50 drives the mounting base 20 to move back and forth, so that the insulating layer on the terminal is inserted into the U-shaped friction steel needle 40 and can be repeatedly rubbed by the U-shaped friction steel needle 40. Before testing, the height of the U-shaped friction steel pin 40 is adjusted by the lifting component 30 according to the position of the terminal on the plug, so that the terminal can be inserted into the U-shaped friction steel pin 40, and the insulation layer on the terminal can be rubbed by the U-shaped friction steel pin 40 for a length of at least 7mm, thereby adapting to different sizes and models of plugs for wear resistance testing and improving compatibility.

[0018] Furthermore, to adjust the height of the U-shaped friction steel needle 40, the lifting assembly 30 includes a base 31 and a support column 32 that is slidably mounted on the base 10. A lifting block 33 is provided on the top of the support column 32. A locking member 34 for locking or releasing the support column 32 is provided on one side of the base 31. The locking member 34 can be a bolt threaded to the base 10, which locks or releases the support column 32. By releasing the locking member 34, the support column 32 can be raised and lowered on the base 31 to adjust its height. After adjustment, the locking member 34 is tightened to fix the support column 32, thus securing it to the base 31. In other embodiments, the lifting assembly 30 can also use a cylinder to drive the lifting block 33 to move up and down, thereby adjusting the height of the U-shaped friction steel needle 40.

[0019] Furthermore, a connecting rod 42 is provided on the side of the lifting block 33 facing the mounting base 20, and a connecting block 41 is provided at the end of the connecting rod 42. The U-shaped friction steel needle 40 is detachably installed on the end face of the connecting block 41, and then extends towards the mounting base 20 through the connecting rod 42, so that the U-shaped friction steel needle 40 on the connecting block 41 is close to the mounting base 20, so that the plug terminal with the insulating layer can be inserted into the socket of the U-shaped friction steel needle 40. The U-shaped friction steel needle 40 is bolted to the end face of the connecting block 41, which facilitates the replacement of worn U-shaped friction steel needles 40.

[0020] In the above scheme, the mounting base 20 is U-shaped, and a receiving groove for placing the plug is formed in the middle of the mounting base 20. The clamping assembly 60 is set on the top of the mounting base 20. After the plug is placed in the receiving groove, the plug is fixed by the clamping assembly 60, and the side of the plug with the terminal faces the mounting base 20. When the driver 50 drives the mounting base 20 to move back and forth, the terminal with the insulating layer can be inserted into the U-shaped friction steel needle 40 for repeated friction, thereby achieving the purpose of conducting a wear test on the insulating layer.

[0021] Specifically, the clamping assembly 60 includes two screws 61 fixed to both sides of the top of the mounting base 20, and pressure plates 62 with both ends passing through the screws 61. A fixing member 63, which can be a nut, is threaded onto the screws 61 and engages with the screws 61. The pressure plate 62 can move up and down on the screws 61. After the plug is placed in the receiving groove of the mounting base 20, the pressure plate 62 abuts against the top of the plug. By tightening the fixing member 63, the pressure plate 62 presses down to fix the plug, thereby securing the plug to the mounting base 20.

[0022] In the above scheme, the top of the mounting base 20 is formed with a slope 21, the screw 61 is set at the top of the slope 21, and a limiting plate 64 is set at the bottom of the slope 21, so that the limiting plate 64 and the pressure plate 62 form a height difference. When the plug is placed in the receiving groove of the mounting base 20, the limiting plate 64 abuts against the side of the plug, thereby limiting the plug in the horizontal direction, and then the pressure plate 62 presses down to fix the plug.

[0023] Furthermore, a slide rail is provided on the machine base 10, and a movable plate 22 is slidably connected to the slide rail. The bottom of the movable plate 22 is connected to the slide rail via a slider. A mounting base 20 is provided on one side of the movable plate 22. The machine base 10 is electrically connected to the driver 50, thereby controlling the start and stop of the driver 50 through the machine base 10, and thus controlling the start or stop of the test. A fixing block 23 is provided on the side of the movable plate 22 away from the movable plate 22, and the drive end of the driver 50 is connected to the fixing block 23. For example, the driver 50 can be a drive structure composed of a motor and a lead screw, or it can be a cylinder, thereby driving the movable plate 22 to move back and forth along the slide rail. The insulation layer of the terminal can be rubbed by the U-shaped friction steel needle for a length of at least 7 mm.

[0024] In summary, this application's solution involves sliding a mounting base on a machine base, with a lifting assembly on one side of the mounting base, and a U-shaped friction steel pin on the side of the lifting assembly facing the mounting base. A clamping assembly is located on the mounting base, and a driver is positioned on the side of the mounting base away from the U-shaped friction steel pin. After the plug is placed on the mounting base, the terminals of the plug face the U-shaped friction steel pin. The clamping assembly secures the plug to the mounting base, and the driver drives the mounting base to move back and forth, allowing the insulating layer on the terminals to be repeatedly rubbed by the U-shaped friction steel pin after insertion. Before testing, the height of the U-shaped friction steel pin is adjusted using the lifting assembly based on the position of the terminals on the plug, thus adapting to different sizes and models of plugs for wear resistance testing and improving compatibility.

[0025] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
