Point can avoid high voltage arc problem under hypobaric.Also, it is simple and reliable for structure, easy to use, solve polytypic product
In the accessory bottleneck problem of low-atmospheric pressure test link.
As a further improvement of the above technical scheme:
The line three-way hole of crossing is in array distribution.
Multiple installation through-holes for fixing with low pressure test chamber ontology are offered in the transfer block, the installation is logical
Hole is set to the position that transfer block removes recessing backwards to low pressure test chamber body surface.
After gasket is padded in transfer block bottom, transfer block is fixed on by low pressure case connector installation site by screw,
Notice that screw installation procedure need to be installed uniformly, prevents gas leakage.
Circumferentially-spaced distribution of multiple installation through-holes along transfer block.
The material of first sealed colloid and the second sealed colloid is epoxy glue, it is ensured that connecting wire is fixed with transfer block
It is firm, it will not be loosened in turnover, test process.
The inventive concept total as one, the present invention also provides a kind of low pressure test chambers, including low pressure test chamber sheet
Body further includes above-mentioned low pressure test chamber switching device, offers adapter mounting hole on the low pressure test chamber ontology,
The transfer block is fixed on the outer surface of low pressure test chamber ontology and sealing covers the adapter mounting hole.
Compared with the prior art, the advantages of the utility model are:
The low pressure test chamber switching device of the utility model is versatile, design rationally, structure it is simple, it is easy to operate,
It is low in cost, easy to use, solve polytypic product in the accessory bottleneck problem of low-atmospheric pressure test link.Also, sealing effect
Fruit and insulation effect are good, and can avoid high voltage arc problem under hypobaric without any solder joint on device.
Detailed description of the invention
Fig. 1 is the partial profile structure of the low pressure test chamber switching device of the utility model embodiment.
The top view (omitting connecting wire) that Fig. 2 is Fig. 1.
Marginal data: 1, transfer block；11, groove；12, line three-way hole is crossed；13, installation through-hole；2, connecting wire；3, first is close
Adhesive body；4, the second sealed colloid.
Specific embodiment
The utility model is further described below in conjunction with specific preferred embodiment, but does not therefore limit this reality
With novel protection scope.
Embodiment 1:
As depicted in figs. 1 and 2, the low pressure test chamber switching device of the present embodiment, including transfer block 1 and several connections
