Quick plugging device of plug and socket

Abstract

The invention discloses a quick plugging device for a plug and a socket. The quick plugging device comprises the plug and the socket, clamping jaws are arranged at the two ends of the socket, the clamping jaws are fixedly connected to the socket through nuts, and conical lock hooks are arranged at the ends of the clamping jaws; a clamping sleeve is arranged on the plug, and the clamping sleeve isfixedly connected to the plug through a limiting sleeve and a locking sleeve; after the socket is plugged with the plug, the conical latch hook of the clamping jaw is clamped with the clamping grooveof the clamping sleeve; and an unlocking rod is arranged in the locking sleeve, a pressing ring is arranged at one end of the unlocking rod, a closing ring is arranged at the other end of the unlocking rod, and the unlocking rod is sleeved with a spring. The device is simple in structure, easy to machine and low in machining cost. When the plug is connected with the socket, the plug is inserted into socket, and the conical latch hook step is arranged on the jack catch of the socket. When the plug is inserted into the socket, the clamping jaws automatically contract under the acting force of the clamping sleeve holes, when the plug is inserted in place, the conical locking hooks of the clamping jaws naturally reset under the acting force of the elastic arms, the steps of the conical lockinghooks of the clamping jaws in the socket are directly clamped with the clamping grooves of the clamping sleeve of the plug, and the purpose of quick connection is achieved.

Description

technical field [0001] The invention relates to a quick plug-in and pull-out device of a plug socket, which belongs to the technical field of quick connection. Background technique [0002] The locking methods of the existing plug and socket include thread locking, steel ball locking, bayonet locking and the like. [0003] In the prior art, the invention patent (publication number CN2583826) applied by Zhang Wenhui discloses a rotating safety power socket with a plug locking mechanism, including a housing upper cover, a housing lower seat, a jack, a rotating shaft and wiring Composed of poles, a right-angled trapezoidal space is formed between the inclination of the inner side of the terminal and the jack rotation shaft, and a right-angled trapezoidal conductor with a plug locking mechanism is embedded in the right-angled trapezoidal space, and a pair of right-angled trapezoids are lifted at the lower end of the jack rotation shaft Convex wings of an electrical conductor. ...

Problems solved by technology

[0005] However, some of these existing locking methods have complex structures and are difficult to process; some are bulky and not suitable for use in small connection spaces; and some have relatively high processing costs.

There are defects and deficiencies in existing locking structures in products that have strict requirements on product volume and product cost, and need to be further improved
