[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A MOSFET testing device includes a testing platform 1, with a plurality of testing seats 2 distributed on the top of the testing platform 1. Clamping members 3 are provided on both sides of the top of the testing seats 2. A pair of clamping members 3 are opened and closed by a reset structure 4 for clamping MOSFETs and for closing and protecting the testing socket.

[0023] The clamping member 3 is provided with a stop structure 5 at its bottom. The pair of clamping members 3 are unfolded through the stop structure 5 to facilitate dust removal and cleaning of the detection port.

[0024] It should be added that the principle of the detection unit is existing technology. The detection is mainly based on the detection pins to determine whether it is good or bad. Specifically, a MOSFET usually has three pins: gate (G), drain (D) and source (S). The pins can be tested using diode testing function.

[0025] Furthermore, a pair of clamping parts 3 close the detection port by fitting together to prevent dust, foreign objects and other impurities from entering the detection port. After long-term use, the clamping parts 3 can be prevented from resetting by the stop structure 5, so that the detection port can be cleaned by removing dust.

[0026] Furthermore, the reset structure 4 includes a shaft 41 and a torsion spring 42. The clamping member 3 has a T-shaped structure and is rotatably connected to the clearance groove 21 at the top of the detection seat 2 via the shaft 41 and the torsion spring 42 at the bottom.

[0027] It should be added that the two ends of the torsion spring 42 are fixedly connected to the clamping member 3 and the detection seat 2 respectively. Under normal circumstances, the clamping member 3 rotates towards the detection seat 2 under the action of the torsion springs 42 on both sides.

[0028] Further, the detection seat 2 is provided with an opening communicating with the clearance slot 21 at the middle of the top end, and each of the two opposite sides of the top of the pair of clamping members 3 is provided with an abutting portion 31, and the two abutting portions 31 are matched and matched with the top opening of the detection seat 2.

[0029] More specifically, the two abutting portions 31 are provided with a guide inclined surface 32 at the top of the opposite side, and a clearance inclined surface 33 at the bottom.

[0030] In this embodiment, the pair of clamping members 3 reduces the friction generated by the resistance between the pins and the MOS tube through the guide inclined surface 32, and the clearance inclined surface 33 is used to avoid the MOS tube.

[0031] In general, the stop structure 5 includes an extension 51, and the bottom of the clamping member 3 extends outwardly to form the extension 51 near one side of the clearance slot 21, and the extension 51 has a protruding end, and the side wall of the clearance slot 21 has a protruding structure 22, and the extension 51 is in contact with the protruding structure 22 by rotating.

[0032] Finally, it also includes a deformation cavity 52, and the bottom of the clamping member 3 is provided with the deformation cavity 52 communicating with the two sides near the extension 51, and the extension 51 avoids and contacts the protruding structure 22 through the deformation cavity 52.

[0033] It is worth mentioning that the clamping member 3 is preferably made of rubber, plastic and other materials with deformation ability, wherein the protruding structure 22 and the protruding end are arranged in a staggered manner in an up-down relationship;

[0034] After the clamping member 3 is rotated to a certain extent, the extension 51 contacts the protruding structure 22, and when the clamping member 3 is continuously rotated by manual intervention, the protruding end of the extension 51 avoids the protruding structure 22 through the deformation cavity 52, and after the deformation is restored, the side wall of the extension 51 contacts the clearance slot 21 and the protruding structure 22, preventing the clamping member 3 from resetting;

[0035] In addition, the protruding structure 22 is in an arc structure.

[0036] Working mode; when working, the pair of clamping members 3 clamps the MOS tube under the action of the reset structure 4, and the pins of the MOS tube are movably inserted into the detection socket for detection by the monitoring unit;

[0037] When not detecting, the pair of clamping members 3 shields and protects the detection socket by being matched and folded, and when long-term use needs to be cleaned, the clamping member 3 can be directly rotated, and because the protruding structure 22 and the protruding end are arranged in a staggered manner in an up-down relationship, the extension 51 is in contact with the protruding structure 22 after being rotated to a certain extent.

[0038] Then, the protruding end of the extension 51 avoids the protruding structure 22 by the deformation cavity 52, and after the deformation is restored, the sidewall of the extension 51 is in contact with the displacement slot 21, and the clamping piece 3 is prevented from resetting, so as to clean the detection socket.

[0039] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
