[0023] Reference Figures 1 to 6The embodiment of the present application provides a TOLL to TO-220 package test socket, including a TO-220 package 1, a TOLL package 2 is arranged inside the TO-220 package 1, the TO-220 package 1 includes a shell 11, a pin 12 is fixedly installed on the front of the shell 11, a fixing cover 13 is clamped on the back of the shell 11, and a fixing groove 16 is opened inside the shell 11 and the fixing cover 13, the TOLL package 2 includes a TOLL body 21, the TOLL body 21 is plugged into the inside of the fixing groove 16, and a first contact 17, a second contact 18 and a third contact 19 are fixedly installed inside the fixing groove 16. The pins 12 are, from left to right, the first G pin, the first D pin, the first S pin The first contact 17 is electrically connected to the first S pin, the second contact 18 is electrically connected to the first G pin, and the third contact 19 is electrically connected to the first D pin. The second S pin 22, the second G pin 23, and the second D pin 24 are fixedly mounted on the bottom of the TOLL body 21. The second S pin 22 is in contact with the first contact 17, the second G pin 23 is in contact with the second contact 18, and the second D pin 24 is in contact with the third contact 19. The left-right length of the bottom end of the TOLL body 21 is 10 mm, the front-to-back length of the bottom end of the TOLL body 21 is 11.5 mm, and the thickness of the TOLL body 21 is 2.3 mm. The length, width, and height of the interior of the fixing slot 16 are the same as those of the TOLL body 21.
[0024] The front and rear inner walls of the fixing slot 16 are provided with mating slots, and the protrusions of the second S pin 22, the second G pin 23, and the second D pin 24 are inserted into the corresponding mating slots. A magnet block 14 is fixedly installed on the front of the fixing cover 13, and a card slot 15 is provided on the back of the shell 11, and the magnet block 14 is inserted into the card slot 15. An iron sheet is fixedly installed on the inner bottom of the card slot 15, and the magnet block 14 is adsorbed on top of the corresponding iron sheet.

[0026] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.
[0027] Working Principle: When testing the TOLL package 2, the TOLL package 2 is inserted into the fixing slot 16 and the fixing cover 13 is buckled onto the exposed portion of the TOLL package 2. While the fixing cover 13 is buckled onto the outside, the magnet block 14 is inserted into the locking slot 15. The magnet block 14 attracts the internal iron sheet to fix the fixing cover 13 to the outside of the TOLL package 2, thereby fixing the TOLL package 2. After the fixing is completed, the second S pin 22, the second G pin 23, and the second D pin 24 contact the first contact 17, the second contact 18, and the third contact 19, respectively, thereby electrically connecting the first and second S pins, the first and second D pins, and the first and second G pins, respectively. This converts the TOLL package 2 into a TO-220 package 1, thereby facilitating testing of the TOLL package 2. After the test is completed, the fixing cover 13 is removed from the housing 11 and the TOLL package 2 can be removed by manually grasping the exposed portion of the TOLL package 2.
