An anti-loosening high-temperature ceramic plug

Abstract

The invention relates to an anti-loosening high-temperature ceramic plug, which includes a spline housing and a connecting nut. Two annular grooves are arranged on the inner side of the rear end of the connecting nut, which are stepped from front to back. The annular groove is used to assemble the second gasket coaxially sleeved on the outer peripheral surface of the spline housing and the front end is limitedly matched with the convex key on the outer peripheral surface of the spline housing. The annular groove at the rear end is used to assemble the front end surface and the second The shims stop and cooperate with the retaining ring; the outer peripheral surface of the spline housing is also provided with a sleeve for preventing the retaining spring from breaking away from the annular groove, which is realized by the second gasket and the retaining ring assembled on the spline housing. Axial stopper. In the present invention, the existing one-piece stepped gasket is changed into two parts, the stopper and the gasket. The gap between the circlip and the baffle is widened, and the circlip has no escape space when subjected to high-level vibrations, thereby preventing the tail of the plug from loosening.

Description

technical field [0001] The invention relates to the technical field of high-temperature connectors, in particular to an anti-loosening high-temperature ceramic plug. Background technique [0002] At present, most of the anti-loosening mechanisms of the circular electrical connectors are clamped by the rear circlip. The one-piece stepped gasket that presses the circlip into the card slot provides a space for the circlip to be installed, and the gap between the gasket and the circlip is relatively large. In high levels of vibration, the circlip is continuously stressed for a long time, so that the expansion force is reduced, which is likely to cause the circlip to come out of the connecting nut. That is to say, when the existing connectors are used in high-temperature and high-level vibration environments, the product may fall apart and the circlip may fall out. Contents of the invention [0003] The purpose of the present invention is to provide a new type of anti-looseni...

Problems solved by technology

In high levels of vibration, the circlip is continuously stressed for a long time, so that the expansion force is reduced, which is likely to cause the circlip to come out of the coupling nut

That is, when the existing connectors are used in high-temperature and high-level vibration environments, the product may fall apart and the circlip may fall out.
