Utility model content
The technical problems to be solved in the utility model is:A kind of voltage-withstand test for the equipment with video interface is provided to fill It puts, to solve the input line of existing pressure resistant testing device using clamp, output line test probe, in calibration tape video interface During the pressure-resistant performance of equipment, clamp, which clamps conducting wire, can cause circuit unstable, and test probe is more unstable and does not allow to be fixed easily On the ground terminal of equipment the technical issues of.
To achieve these goals, the specific technical solution that the utility model is taken is:It is a kind of to be used for video interface The pressure resistant testing device of equipment, including a pressure tester, an input line and an output line, one end of the input line with it is resistance to The High voltage output port connection of pressure tester, one end of the output line and the grounding ports of pressure tester connect, feature Be, including a socket and a quick coupling, the zero curve and firewire of the socket by a lead-out wire short circuit and the lead-out wire with The other end welding of input line and weld are equipped with insulation sleeve, and one end of the quick coupling has one for entangling equipment under test The sleeve of video interface shell, the other end of the quick coupling and the other end of output line weld and weld is equipped with insulation Set.
Further, the interior shape of the sleeve is identical with the shell shape of the video interface of equipment under test, to cover Cylinder is closer, on the shell for the video interface for being sleeved on equipment under test securely, so as to ensure reliable ground.
Further, the lead-out wire and the other end of input line weld and electrician's glue are equipped between weld and insulation sleeve Band, to further increase the insulation performance of input line.
Further, the other end of the other end of the quick coupling and output line welds and between weld and insulation sleeve Equipped with electrical adhesive tape, to further increase the insulation performance of output line.
Compared with prior art, the beneficial effects of the utility model are:In the resistance to pressure of the equipment of calibration tape video interface Can when, the attaching plug of equipment under test is inserted into socket, and video interface is entangled in quick coupling, this mounting means securely and conveniently, no Circuit can be caused unstable, ensure the validity and stability of voltage-withstand test, while it is also ensured that operating personnel are not shocked by electricity.
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.
