The mounting hole of the perforation in portion；A binding post is equipped in the mounting hole, the both ends of the binding post extend out to the peace
It fills except hole；Spacer sleeve is set there are two the intermediate ring being located in mounting hole on each binding post, and the both ends of the binding post are equipped with
Insulation sleeve and nut, the intermediate ring is by the axis location of the binding post in the center of the mounting hole, two centres
An O-ring seal is equipped between ring and between insulation sleeve and intermediate ring；The insulation sleeve and nut are for compressing axially
The intermediate ring is to compress the O-ring seal.
An embodiment according to the present utility model, the pedestal is equipped with the shield for accommodating the binding post, described
The top of shield is equipped with cover board to be opened/closed.

As shown from the above technical solution, it the advantages of the utility model and has the active effect that
The technology of vacuum leak and heatproof when the utility model termination avoids vacuum environment lead to atmospheric environment
Problem, while dismantling simple and fast, it improves work efficiency, reduces use cost.
Detailed description of the invention
Its example embodiment is described in detail by referring to accompanying drawing, above and other feature and advantage of the utility model will
It becomes readily apparent from.
Fig. 1 is the schematic diagram of the heatproof vacuum-resistant termination of one embodiment of the utility model.
In figure: 1, pedestal；2, flange；3, binding post；4, O-ring seal；5, intermediate ring；6, insulation sleeve；7, nut；8, prevent
Shield；9, cover board.
Specific embodiment
Example embodiment is described more fully with reference to the drawings.However, example embodiment can be with a variety of shapes
Formula is implemented, and is not understood as limited to embodiment set forth herein；On the contrary, thesing embodiments are provided so that this is practical new
Type will be full and complete, and the design of example embodiment is comprehensively communicated to those skilled in the art.It is identical in figure
Appended drawing reference indicates same or similar structure, thus the detailed description that will omit them.
As shown in Figure 1, the utility model embodiment discloses a kind of termination of heatproof vacuum-resistant, it to be used for vacuum
Conducting wire in vacuum tank can be connected in the power control cabinet except vacuum tank by the vacuum tank of drying equipment.This termination packet
A pedestal 1 is included, which is removably sealedly attached on the flange 2 of vacuum tank, and annular groove, the ring are equipped on flange 2
Sealing ring is equipped in shape slot, for being sealed cooperation with the end face of pedestal 1.At least one is provided on pedestal 1 for connecting
The mounting hole for passing to the perforation inside vacuum tank, is equipped with a binding post 3 in mounting hole, and the both ends of the binding post 3 are stretched
Out to except mounting hole.Two mounting posts are shown in FIG. 1, but the quantity of mounting hole and binding post is not intended to limit, it can be with
It is configured as needed.
Spacer sleeve is set there are two the intermediate ring 5 being located in mounting hole on each binding post 3, which is used for wiring
The axis location of column 3 is in the center of mounting hole, so that mounting hole and binding post 3 are in the state of coaxial line.The both ends of binding post 3
