[0040] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0041] See also Figure 1 , Figure 2 and Figure 3 As shown, one or more embodiments of the present application provide a debugging station AC test needle plate tooling, which includes: a guide device 101, a needle plate 102 and a connecting rod structure 103, the guide device 101 includes a guide rail 104 and a movable frame 105, the movable frame 105 is slidably arranged on the guide rail 104; the needle plate 102 includes a plate body 107 and a plurality of test needles 106, the test needles 106 are installed on the plate body 107, the needle plate 102 is fixed on the movable frame 105, and the movable frame 105 can drive the needle plate 102 to move, so that the test needles 106 correspond to the tested device 300. The connecting rod structure 103 includes a first connecting rod 108, a second connecting rod 109 and an operating connecting rod 110, one end of the first connecting rod 108 is hinged to the movable frame 105, the other end of the first connecting rod 108 is hinged to the operating connecting rod 110, the operating connecting rod 110 is hinged to one end of the second connecting rod 109, the other end of the second connecting rod 109 is hinged to the guide rail 104, the operating connecting rod 110 has a strip-shaped through hole 111, and the movable frame 105 is provided with a guide pin 112, which is penetrated by the strip-shaped through hole 111. Figure 1 and Figure 2 The device under test in FIG. 1 is a simplified schematic diagram.

[0042] At least one embodiment of the present application provides a debugging station AC test needle plate tooling, after the needle plate 102 with multiple test needles 106 is installed on the mobile frame 105, the operating link 110 is used to drive the linkage of the first link 108 and the second link 109, so that the mobile frame 105 can move along the guide rail 104. When the operating link 110 drives the first connection and the second link 109 to be linked, the guide pin 112 can move along the length direction of the strip through hole 111, and the guide pin 112 is connected to the operating link 110, and the first link 108 is hinged to the mobile frame 105, so that the mobile frame 105 can move along the guide rail 104. A stable guide is provided. This design effectively prevents the movable frame 105 from shaking or deflecting during the sliding process, thereby ensuring the stability of the test. After the test pin 106 contacts the corresponding terminal 301 on the tested device 300, a one-to-one contact connection between multiple test pins 106 and multiple different terminals 301 is quickly achieved, so as to implement the test of the tested device 300.

Exemplarily, the other end of the second connecting rod 109 has a pin hole, and the third pin 128 passes through the third hinge hole 127 and the pin hole at the other end of the second connecting rod 109 to realize the hinge between the second connecting rod 109 and the mounting plate 129.

[0051] See also Figure 7 and Figure 8 As shown, in some embodiments, the distance between the third hinge hole 127 and the guide rail 104 is greater than the distance between the second hinge hole 125 and the guide rail 104.

Exemplarily, the distance between the first hinge hole 123 and the guide rail 104 is the distance between the hole center of the first hinge hole 123 and the first surface 130 of the guide rail 104, so that when the mobile frame 105 is located at the detection position, the distance between the hole center of the second hinge hole 125 and the hole center of the first hinge hole 123 and the first surface 130, respectively, is smaller than the distance between the hole center of the third hinge hole 127 and the first surface 130, and the hole center of the first hinge hole 123 is between the dead point of the connecting rod structure 103 and the first surface 130, so that the connecting rod structure 103 cannot be linked, thereby realizing the locking function of the connecting rod structure 103.

[0054] See also Fig. 9As shown, in some embodiments, the needle plate 102 also includes a spring 132, the needle plate 102 has a front side 133 and a rear side 134, the spring 132 is sleeved on the test needle 106, one end of the spring 132 abuts against the step surface 136 on the test needle 106, and the other end of the spring 132 abuts against the front side 133; when in use, the front side 133 faces the device under test 300; the test needle 106 has a slot, and a retaining spring 135 is arranged in the slot, and the retaining spring 135 abuts against the rear side 134, so that the distance between the end face of the contact end 113 of the test needle 106 and the front side 133 can be changed. When the surfaces of multiple different terminals 301 on the device under test 300 are not on the same plane, when the end face of the contact end 113 of the test needle 106 abuts against the surface of the terminal 301, different test needles 106 will compress their corresponding springs 132.

[0055] Combination Figures 1 to 3 As shown, in one or more embodiments, the present application also provides a debugging station, which includes: a table panel 201 and a debugging station AC test needle board tooling in any embodiment. The table panel 201 is provided with a first positioning block 202 and a second positioning block 203 that can be detachably fixed. The first positioning block 202 and the second positioning block 203 can position the position of the device under test 300 on the table panel 201, so that when the test board on the mobile frame 105 contacts the terminal 301 on the device under test 300, the device under test 300 will not move. The number of the first positioning blocks 202 can be multiple, and the number of the second positioning blocks 203 can be multiple, so as to adapt to the devices under test 300 of different sizes. In addition, the number of the debugging station AC test needle board tooling in the debugging station can be one or more. When the number of the debugging station AC test needle board tooling is multiple, this can meet the test of the device under test 300 with a larger number of terminals 301. The wire connected to the test needle 106 passes through the threading hole 204 on the table panel 201 to connect with the measuring instrument. The second surface 131 of the guide rail 104 contacts the table top 201 ; the guide rail 104 can be fixed to the table top 201 by screws.
