In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0020] like Figure 1-Figure 3 As shown, a test seat body 100 disclosed in the present application includes a base 10, a rotating clamp 40, a pressure cover 20 and a positioning member 30 for installing a DUT 50, the pressure cover 20 is slidably connected to the base 10, an elastic member is connected between the base 10 and the pressure cover 20, a mounting groove 13 is provided on the base 10, the positioning member 30 is installed in the mounting groove 13, and a signal pin 60 is also provided in the mounting groove 13, the rotating clamp 40 is rotatably connected to the base 10, one end of the rotating clamp 40 is connected to the pressure cover 20, and the other end of the rotating clamp 40 abuts against the DUT 50, when the pressure cover 20 slides upward, the pressure cover 20 causes one end of the rotating clamp 40 to press against the DUT 50, so that the pin 51 of the DUT is electrically connected to the signal pin 60; when the pressure cover 20 slides downward, one end of the rotating clamp 40 is away from the DUT, and the DUT 50 can be replaced or placed at this time.
[0021] In the above embodiment, the test seat body 100 is connected to the signal of the test device for sending the test signal, and the test seat body 100 can be installed in the test device. The test seat body 100 includes a pressure cover 20 and a positioning member 30 for installing the device to be tested 50. The device to be tested 50 is installed on the positioning member 30. When the pressure cover 20 slides upward, the pressure cover 20 causes one end of the rotating clamp 40 to press against the device to be tested 50, so that the pin of the device to be tested 50 and the signal pin 60 are more firmly electrically connected. The device to be tested 50 can receive the test signal (power signal) of the test device, and the device to be tested can be tested. Therefore, the test seat body 100 does not need to plug the device to be tested into the test seat, which facilitates testing and improves the test effect.
[0022] The test piece 50 may be a capacitor, a diode, a chip, etc. The elastic member facilitates the upward sliding reset of the pressure cover 20, and the rotating clamp 40 is similar to a "seesaw".
[0023] like Figure 1 As shown, in a preferred embodiment, the test seat body 100 further includes a bottom plate 11, the base 10 is fixed to the upper end of the bottom plate 11, and the signal pin 60 passes through the bottom plate 11 and is electrically connected to the test device. Figure 2 As shown, the base 10 is also provided with a bayonet 131, a through hole 16, a pinhole 15 and a slide groove 14, the positioning member 30 is engaged in the bayonet 131, the elastic member is a spring 21, and the spring 21 is arranged in the through hole 16. The signal needle 60 passes through the pinhole 15, and the pressure cover 20 is provided with a slide 23 corresponding to the slide groove 14, and the pressure cover 20 is slidably connected with the base 10 through the slide 23.
[0024] In the above embodiment, the bayonet 131 makes the positioning member 30 more stable, the positioning member 30 is convenient for installing the DUT 50, and the bottom plate 11 facilitates the installation of the base 10 on the test device. When the pressure cover 20 is pressed down, the slide 23 slides in the slide slot 14, the spring 21 stores energy, and one end of the rotating clamp 40 moves away from the DUT 50; when the pressure on the pressure cover disappears, the pressure cover 20 can be reset under the elastic force of the spring 21, and one end of the rotating clamp 40 presses against the DUT 50, so that the pin 51 of the DUT 50 and the signal pin 60 are more stably connected.
[0025] like Figure 4As shown, in a preferred embodiment, the positioning member 30 includes a clamping plate 33 and a mounting platform 31 fixed on the clamping plate 33, the mounting platform 31 is fixed in the clamping port 131, and baffles 32 are fixed at both ends of the mounting platform 31. The slide 14 is provided with a positioning column 121, and the slide 23 is provided with a limiting hole 231, and the positioning column 121 is arranged in the limiting hole 231. Figure 5 As shown, the rotating clamp 40 includes a rotating shaft 42 and a curved plate 41 rotatably connected to the rotating shaft 42 . The rotating shaft 42 is fixed on the base 10 . One end of the curved plate 41 is provided with a pressing end 411 or a clamping end (not shown) for pressing the test piece 50 .
[0026] In the above embodiment, the body of the DUT 50 can be clamped between the two baffles 32 .
[0027] The limiting hole 231 can only slide with the slide 23 above and below the positioning column 121 (or the positioning column 121 can only slide in the limiting hole 231), thereby limiting the slide 23 and the gland 20, and preventing the gland 20 from falling off. The pressing end 411 is conducive to pressing the test piece 50, and the clamping end has a clamping opening for clamping the test piece 50. The clamping end is conducive to installing or replacing the test piece 50, and can make the test piece 50 installed more firmly.
[0028] In a preferred embodiment, Figure 3 As shown, the gland 20 includes a frame 22, a transfer portion 24 is further provided at the lower end of the frame 22, the other end of the curved plate 41 is fixedly connected to the transfer portion 24, and a positioning hole 221 is further provided at the upper end of the gland 20. The test seat 100 also includes a protective clip 52 for protecting the test piece 50, and the protective clip 52 includes a grounding terminal 521 and a notch 522 for clamping the test piece 50. The signal needle 60 includes a needle head 61, and a plum blossom terminal 611 is provided on the needle head 61 for contacting the pin 51 of the test piece 50.
[0029] In the above embodiment, the DUT 50 can be placed in the mounting groove 13 from the middle of the frame 22, the adapter 24 facilitates the connection of the rotating shaft 42, and the positioning hole 221 can be clamped with the base 10, so that the pressure cover 20 cannot slide. One end of the protective clip 52 is metal, and the grounding end 521 can be used for grounding. Some DUTs 50 (chips) also come with protective clips 52. The signal pin 60 can be a probe, and the plum blossom end 611 can increase the contact area and facilitate electrical connection.
[0030] In summary, the test socket 100 drives the rotating clamp 40 to press or clamp the DUT 50 through the pressure cover 20, so that the pin 51 of the DUT 50 is more firmly electrically connected to the signal pin 60, without the need for the pin 51 to be plugged into the test socket 100, thereby facilitating testing and improving testing results.
