iecc19 plug anti-falling structure

Abstract

The invention discloses a novel anti-drop structure for an IECC19 plug. The structure comprises a plug body; the lower part of the plug body is inwards provided with a plug bush; the upper part of the plug body is inwards provided with a guide slot parallel to the plug bush; a button cavity extends from the other end of the guide slot perpendicularly upwards; a guide rod is arranged in the guide slot; a limiting block extends downwards from one end of the guide rod; the middle of the bottom surface of the limiting block is inwards provided with a V-shaped groove; a button extends perpendicularly upwards from the other end of the guide rod; the button is positioned in the button cavity; a boss extends upwards from the vicinity of the middle of the bottom surface of the guide slot; the upper end face of the boss is in contact with the bottom surface of the guide rod; a spring is arranged between the boss and the limiting block; one end of the spring is supported against the boss, and the other end of the spring is supported against the limiting block. The novel anti-drop structure is simple, and convenient to use; as the whole anti-drop device is an integral built-in structure, the whole anti-drop device is attractive and is fastened closely and reliably; the requirement on the structural size of the plug is not high.

Description

technical field [0001] The invention relates to the field of communication equipment processing and manufacturing, in particular to an IECC19 plug-off prevention structure. Background technique [0002] Most of the common IECC19 plugs are in-line convex structures. During daily use, there are often phenomena of falling off or poor contact at the interface. The plug, the anti-off structure of this kind of plug is mostly arranged on the periphery of the plug. The whole is composed of a metal rod, a plastic buckle and a bolt. The metal rod is installed between the bolts and can rotate at both ends. The plastic buckle is stuck on the metal rod, rotates with the metal rod, and is buckled at the joint of the plug and the wire. So as to achieve the anti-off function. But this structure is not only unattractive, but also unreliable, and it is easy to come out if the buckle is improper, and it has relatively high requirements on the size of the plug structure, so it may not be suit...

AI Technical Summary

Problems solved by technology

However, this structure is not only unsightly, but also unreliable, and it is easy to come out if the buckle is improper, and it has relatively high requirements on the size of the plug structure, so it may not be suitable for other types of plugs
