Description

Technical Field

[0001] The utility model relates to the technical field of test equipment, in particular to a pluggable test device. Background Art

[0002] Before the electronic devices leave the factory, they need to be electrically connected to a functional test circuit board (referred to as "functional board" for short) for electrical function testing. Generally, different types of electrical function tests require the use of different functional boards. Therefore, the test personnel need to frequently perform the installation and disassembly operations of the electronic devices and the functional boards.

[0003] When the size of the functional board is small, the operation is relatively convenient. However, when the size of the functional board is large, it is very time-consuming and laborious to frequently perform the installation and disassembly operations of the functional board.

[0053] For the plug-and-play test device provided in this embodiment, first place the device under test in the test point 201, then place the functional board 100 on the sliding component 302, and rotate the rotary handle 303 forward, so that the sliding component 302 drives the functional board 100 to move upward and insert into the test fixture 2, then the functional board 100 can be electrically connected to the device under test; after the test is completed, rotate the rotary handle 303 in the reverse direction, so that the sliding component 302 drives the functional board 100 to move downward and pull out from the test fixture 2, then the functional board 100 can be taken out, and further the functional board 100 can be replaced.

[0054] Therefore, the plug-and-play test device provided by the present utility model can effectively solve the problem of inconvenient installation and disassembly of the functional board 100.

[0055] Optionally, at the position of the bottom of the test fixture 2 corresponding to each function board 100, a test interface 202 for plugging and unplugging connection with the corresponding function board 100 is provided. Correspondingly, at the top position of the function board 100, a plug-in terminal for plugging and unplugging connection with the test interface 202 is provided.

[0056] See Figure 4 and Figure 5 As shown in and, the fixed base 301 includes a fixed horizontal plate 3011 and a fixed vertical plate 3012 fixed to one end of the fixed horizontal plate 3011. Among them, the fixed vertical plate 3012 is slidably connected to the sliding assembly 302 up and down. Further, a guide rail slider assembly is provided between the fixed vertical plate 3012 and the sliding assembly 302 to improve the smoothness and stability of the sliding assembly 302 when sliding up and down.

[0057] In this embodiment, the sliding assembly 302 includes a sliding seat 3021 and a sliding bar 3022 slidably connected to the sliding seat 3021 in the horizontal direction. Among them, the sliding bar 3022 is provided with a fixing hole 3022a for fixing the function board 100. Optionally, the sliding seat 3021 is provided with an installation slot 3021a for plugging and unplugging connection with the sliding bar 3022. Further, a fixed magnet is provided on the sliding seat 3021, and a movable magnet 304 for magnetically connecting with the fixed magnet is provided on the sliding bar 3022.

[0058] The rotating handle 303 includes an L-shaped handle 3031 and a roller 3032. The corner position 3031a of the L-shaped handle 3031 is hinged to the other end of the fixed horizontal plate 3011. The roller 3032 is rotatably installed at one end of the L-shaped handle 3031. Among them, a horizontal guide groove 3021b for rolling connection with the roller 3032 is provided at the side position of the sliding seat 3021.

[0059] At the beginning, the roller 3032 is located at one end of the horizontal guide groove 3021b close to the fixed vertical plate 3012, and the sliding seat 3021 is located at a lower position. The plug-and-play test device provided in this embodiment is used as follows:

[0060] S10: Open the door panel 101;

[0061] S20: Take out the sliding bar 3022 from the installation slot 3021a, and install and fix the lower end of the function board 100 on the fixing hole 3022a through a fastening bolt or the like. Then hold the function board 100 by hand and insert the sliding bar 3022 into the installation slot 3021a. When it is felt that the movable magnet 304 is magnetically attracted and positioned by the fixed magnet, it can be explained that the sliding bar 3022 is inserted in place (the plug-in terminal at the top of the function board 100 is directly below the test interface 202);

[0062] S30: Rotate the L-shaped handle 3031 so that the roller 3032 moves along the transverse guide groove 3021b to an end far from the fixed vertical plate 3012;

[0063] During the movement of the roller 3032, the sliding seat 3021 will be lifted upward by the roller 3032, so that the insertion terminals at the top of the function board 100 are inserted upward into the test interface 202, thereby realizing the electrical connection between the function board 100 and the device under test in the test point 201, and then using the function board 100 to perform electrical function tests on the device under test.

[0064] When the function board 100 needs to be replaced, only need to rotate the L-shaped handle 3031 in the reverse direction so that the roller 3032 moves to one end of the transverse guide groove 3021b close to the fixed vertical plate 3012. This embodiment will not be elaborated here.

[0065] In summary, the plug-and-play test device provided in this embodiment has the following advantages: Rotate the rotary handle 303 forward, so that the sliding assembly 302 drives the function board 100 to move upward and insert into the test fixture 2, then the function board 100 can be electrically connected to the device under test; after the test is completed, rotate the rotary handle 303 in the reverse direction, so that the sliding assembly 302 drives the function board 100 to move downward and pull out the test fixture 2, then the function board 100 can be taken out, and then the function board 100 can be replaced, thereby solving the problem of inconvenient installation and disassembly of the function board 100.
