Plug incapable of coming loose

Abstract

The present invention discloses a plug incapable of coming loose. The plug includes a plug body and an insulating sleeve. The upper surface of the plug body is equipped with a first groove at the center. The other end of a connecting shaft is connected with an upper plug. A connecting spring is disposed inside the lower surface of the plug body. A lower plug is embedded in the upper surface of each steering wheel. A return spring is connected between the inner side surface of the lower end of an inclined hook and the outer side surface of the lower end of the lower plug. The insulating sleeveis disposed on the surface of the plug body. According to the plug incapable of coming loose, the lower plug can be freely rotated in the steering wheel by the assembly between the steering wheel andthe lower plug. Thus, the lower plug can be adapted to various jacks, and can be prevented from falling off when unplugged. The two steering wheels are connected by the connecting spring, and can slide in a second groove, so that the distance between the two lower plugs can be changed, thereby improving the loosening problem of the plug.

Description

technical field [0001] The invention relates to the technical field of plugs, in particular to a non-loosening plug. Background technique [0002] The connectors of general electronic products and the pins of electrical appliances are called plugs, household AC power plugs and sockets, with rod-shaped or copper-shaped protruding male connectors, which are physically inserted into female connector-type power sockets with slots or recesses, The size is an important technical requirement related to whether the plug, socket and converter can be used safely and whether they meet the general interchangeability requirements to avoid wrong insertion. Unqualified size will affect the user's use or cause poor contact, wrong insertion and other hidden dangers. If it is light, it will damage the equipment, and if it is heavy, it will cause fire and electric shock. [0003] The plugs on the market will loosen after a long time, resulting in poor contact or electric leakage, which is bot...
