Structure of pressure-resistant sealed connecting cover

Abstract

The invention discloses a structure of a pressure-resistant sealed connecting cover. The structure comprises a shell which is provided with an outgoing line flange end surface. The structure also comprises a pin base, a flange, a compressing sleeve, an end cap, waterproof connectors, plug pins and sintered glass. The pin base is arranged on the internal side of the flange. The flange is fixedly connected on the outgoing line flange end surface of the shell through screws. The flange locates the pin base on the shell. The pin base is provided with multiple threading holes. The sintered glass isarranged in the threading holes. One plug pin is plugged in the sintered glass of each threading hole. The compressing sleeve is welded on the flange. The end cap is welded on the compressing sleeve.The waterproof connector is fixed on the end cap. The pin base and the compressing sleeve are separated so that the welding space is not constrained by the compressing sleeve in case of welding on the socket and the welding space is sufficient. According to the structure, the connecting part can be compressed and sealed through screw connection and silicon pad sealing like common flange connection so that the structure is ingenious, the components can be reduced and installation can be simplified without changing the connection mode.

Description

Technical field: [0001] The invention relates to a structure of a pressure-resistant sealed wiring cover. Background technique: [0002] At present, the sealing outlet of the magnetic bearing and the sensor mainly adopts the sealing structure of drilling holes on the rectangular plate and glass sintering pins. The sealing element and the casing are sealed by O-rings and connected by bolts. The protective cover is used to isolate the outlet wire from the outside world. However, due to the large internal pressure inside the casing, the selection of the O-ring model, the design check of the rectangular plate, and the specification and quantity of the bolts all require a certain strength calculation and check, and the design process is more complicated. In addition, although the design of the protective cover isolates the socket from the outside world and protects the socket, it takes up too much space, and needs to process threaded holes on the casing for installing the protec...

AI Technical Summary

Problems solved by technology

However, because there is a large internal pressure inside the casing, the selection of the O-ring type, the design check of the rectangular plate, and the specification and quantity of the bolts all need to be calculated and checked for certain strength, and the design process is more cumbersome.

Moreover, although the design of the protective cover isolates the socket from the outside world and protects the socket, it takes up too much space, and it is necessary to process threaded holes for installing the protective cover on the casing, which increases the processing task
