[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] Example 1, referring to Figure 1-4 An experimental device for testing the pins of a locomotive plug includes a support plate 1, a first support block 2 and a second support block 10 fixed on both sides of the upper end face of the support plate 1, a test component connected between the first support block 2 and the second support block 10, a cooling component connected to the upper end of the first support block 2 and the second support block 10, and a U-shaped frame 6 fixed on the lower end face of the support plate 1, with an elastic support structure connected to the U-shaped frame 6.
[0023] The test assembly includes a sub-plug 12 fixed in the middle of the first support block 2, a female plug 7 fixed in the middle of the second support block 10, a test wire 3 connected between the sub-plug 12 and the female plug 7, and a test bulb 4 connected in series in the middle of the test wire 3.
[0024] The cooling component includes a connecting plate 11 fixed to the upper ends of the first support block 2 and the second support block 10. Both ends of the connecting plate 11 are fixed with inclined plates 8, and cooling fans 9 are installed on both inclined plates 8.
[0025] A heat dissipation cavity 15 is provided on one side of the second support block 10 and around the female plug 7. Heat-conducting fins 16 are fixed at equal intervals in the heat dissipation cavity 15, which improves the heat dissipation effect of the female plug 7.
[0026] The elastic support structure includes a T-shaped rod 13 that is slidably inserted into the middle of the support plate 1 and the U-shaped frame 6. The bottom end of the T-shaped rod 13 is connected to a base 5. A spring 14 is sleeved on the part of the T-shaped rod 13 located between the base 5 and the horizontal section of the U-shaped frame 6. Vibration motors 17 are fixed on both sides of the upper end face of the horizontal section of the U-shaped frame 6.
[0027] Working principle: Connect the two plugs in the front and rear compartments to the male plug 12 and female plug 7 respectively. By turning on the vibration motor 17 and the elastic support of the U-shaped frame 6 by the spring 14, the vibration generated by the vibration motor 17 driving the eccentric block is transmitted to the U-shaped frame 6 and the support plate 1, causing the male plug 12 and female plug 7 to vibrate. During the vibration, observe whether the test bulb 4 lights stably, so as to test the connection stability of the plug pins under vibration. By turning on the two cooling fans 9, the heat-generating parts of the male plug 12 and female plug 7 are cooled down to avoid damage caused by excessive heat during continuous testing and to ensure service life.
