Description of the drawings
Fig. 1 show the structure diagram of the utility model.
Each mark of Fig. 1, pressure tester 1, input line 2, output line 3, socket 4, quick coupling 5 and insulation sleeve 6.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Embodiment 1 is with reference to figure 1, a kind of pressure resistant testing device for the equipment with video interface, including a pressure resistance
Tester 1, an input line 2 and an output line 3, one end of the input line 2 connect with the High voltage output port of pressure tester 1
It connects, one end of the output line 3 is connect with the grounding ports of pressure tester 1, is the prior art above, the utility model
It thes improvement is that, including a socket 4 and a quick coupling 5, the zero curve and firewire of the socket 4 pass through a lead-out wire short circuit
And other end welding and weld of the lead-out wire with input line 2 are equipped with insulation sleeve 6, one end of the quick coupling 5 has one
For entangling the sleeve of equipment under test video interface shell, the other end of the quick coupling 5 is welded with the other end of output line 3
And weld is equipped with insulation sleeve 6.
At present there are many kinds of video interfaces on the market, conventional video interface includes USB interface, DVI interface, HDMI and connects
Mouth and RF interfaces, the video interface have metal shell, and the metal shell of video interface is the casing for connecting equipment under test,
Using this feature, when testing pressure resistance, the attaching plug of equipment under test is directly inserted on the socket 4 in the utility model,
Zero curve and firewire short circuit to be input to all wiring in attaching plug and take high pressure in socket 4, at the same time, by this practicality
Novel quick coupling 5 is sleeved on the video interface of equipment under test, is equivalent to the shell for having accessed equipment under test, and then pressure resistance is surveyed
It tries 1 moment of instrument input high pressure and tests the leakage current of equipment under test, complete voltage-withstand test, insulation sleeve 6 is the anti-leak-stopping in order to insulate
Electricity or operating personnel get an electric shock.
