Description

A kind of fixture for Hi-pot test

Technical field

The utility model relates to a kind of fixture more particularly to a kind of fixtures for Hi-pot test.

Background technique

PTC heater is widely used in electronic apparatus, and PTC heater generally can directly connect with the thermal conductor of metal Touching, so its voltage-resistent characteristic is directly concerning the life security of people, the fixture of existing testing high voltage is test clip, test Folder can only once test a product, not can be carried out batch testing.

Utility model content

In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide one kind for height Press the fixture of test.

Technical solution adopted by the utility model to solve the above technical problems is as follows:

A kind of fixture for Hi-pot test, including control valve, upper clamp plate, lower clamp plate, cylinder and bottom plate, the lower clamp plate It is fixed on bottom plate, which is arranged in parallel with lower clamp plate, which is slidably connected by positioning pin and lower clamp plate, described It is provided with cylinder above upper clamp plate, the cylinder-driven end is connected with upper clamp plate, and having on the bottom plate by connection can The control valve of power supply through and off is controlled, the cylinder is connected with control valve, and the lower clamp plate upper surface is fixed with copper sheet.

Preferably, the control valve includes electronic valve and air throttle, and the electronic valve and air throttle are connect with cylinder.

Preferably, the bottom plate is ambroin.

Preferably, the upper clamp plate lower surface is fixed with one layer of conducting foam.

Compared with the prior art, the advantages of the utility model are:

By increasing the clamping area of fixture, to achieve the purpose that disposably to clamp more products, detection effect is improved Rate saves labour, and the utility model is designed reasonably accords with the demands of the market, and is suitble to promote.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model,

Fig. 2 is the utility model structure diagram.

Specific embodiment

The utility model embodiment is described further with reference to the accompanying drawing:

As shown in Figure 1 with Figure 2, a kind of fixture for Hi-pot test, including control valve, upper clamp plate 2, lower clamp plate 5, gas Cylinder 1 and bottom plate 7, the lower clamp plate 5 are fixed on bottom plate 7, which is arranged in parallel with lower clamp plate 5, which passes through Positioning pin 6 is slidably connected with lower clamp plate 5, and cylinder 1,1 driving end of cylinder and upper clamp plate 2 are provided with above the upper clamp plate 2 It is connected, control valve is fixed on the bottom plate 7, the cylinder 1 is connected with control valve, and 5 upper surface of lower clamp plate is fixed with Copper sheet.

The control valve includes electronic valve 3 and air throttle 4, and the electronic valve 3 and air throttle 4 are connect with cylinder 1, passes through control Electronic valve 3 processed controls the movement of cylinder.

The bottom plate 7 is ambroin, achievees the purpose that insulation by the design of ambroin, people can be prevented electric Wound.

2 lower surface of upper clamp plate is fixed with one layer of conducting foam, can prevent the connecting line transition of PTC heater from squeezing.

Specifically, after multiple PTC heaters being placed on bottom plate 7, then the connecting line on multiple PTC heaters is placed on On the copper sheet of lower clamp plate 5, open electronic valve 3 after, the driving end of cylinder 1 move downward drive upper clamp plate 2 move downward, it is described on A closed circuit is formd after clamping plate 2 and 5 clamping of lower clamp plate, the bottom plate 7 has insulating effect, high pressure is successively used after clamping Style of writing touches PTC fever body case, if the high voltage testing device that short circuit is connected with high pressure pen, which occurs, to be sounded an alarm.

Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to It is so possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is replaced on an equal basis It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution Spirit and scope.
