Totally-closed indirect conductive snap safety socket and mating snap plug

Abstract

The innovatively designed indirect conductive socket and the mating snap plug of the present invention, through indirect conductive communication with the power source, not only effectively avoid arcsparks caused by the collision and friction between the plug and the metal part of the socket and eliminate potential safety hazards, but also greatly reduce the quantity of conductive metal materials. Before the mating operation of the plug and the socket is completed, the conductive connection contact of the socket is in a power-off state. Under the effect of a sleeve sealing ring disposed on the indirect conductive socket, an elastic gasket and a mating sealing ring disposed on the mating snap plug, after the mating operation of the plug and the socket is completed, the conductive connection contact is completely wrapped and protected, and can be used safely in a humid or water environment. When the plug is pulled out of the socket, the conductive connection contact is immediately powered off so as to achieve a good safety protection effect. Further, a fluid conductive medium in the dielectric conductive ball of the present invention is completely enclosed in a closed space, cannotbe leaked or lost, and is safe and reliable to use.

Description

technical field [0001] The invention relates to an electrical accessory, in particular to a fully enclosed indirect conduction buckle-type safety socket and a matching plug. Background technique [0002] In production and life, the use of electric equipment and various electrical appliances or equipment to connect to the power supply, power sockets and matching plugs are essential. For a long time, there have been various types of power sockets and matching plugs on the market, but the way these sockets and matching plugs are connected to the power supply is the same, that is, by inserting the metal strip or metal post on the plug into the elastic metal clip of the socket. connected circuit. [0003] Although this method of plugging and connecting to the power supply is fast and convenient, it also has relatively large defects. One is that when the metal strip or short metal column is inserted into the elastic metal clip of the socket, the impact and friction will generate ...

Problems solved by technology

[0003] Although this method of plugging and connecting to the power supply is fast and convenient, it also has relatively large defects. One is that when the metal strip or short metal column is inserted into the elastic metal clip of the socket, the impact and friction will generate arc sparks, which will cause damage in certain environments. Explosion accidents have great safety hazards; the second is that metal strips or short metal posts are inserted into the elastic metal clips of the socket, which can easily cause loosening and falling off, affecting normal use, and arcs will also be generated during loose friction, forming a safety hazard; It is the metal strip on the plug and the elastic metal clip in the socket, which requires the use of a large amount of metal materials, consumes non-renewable resources, and increases production costs. economic burden

[0004] Compared with the utility model patent of patent number 2019201667453 and the invention patent of application number 2019100937572, a buckle-type safety socket and matching plug are innovatively designed. The plug-in connectors of the plug-in joints...expand the hollow lumen of the elastic sealing tube by pushing and squeezing, and pass through the elastic sealing tube to contact and immerse in the medium sealing box that stores the non-solid conductive medium"... New technical solution It solves many problems such as arc sparks are easily generated when the plug and socket are plugged in the prior art, and a large amount of metal materials are consumed, and it is also kept in a closed state during the plugging or pulling out process, which is safer to use, but the technical solution design is still It is not scientific and reasonable enough, and there are also relatively prominent technical defects; first plug in the power supply, and the probe pins provided with the snap-on plug "expand the hollow lumen of the elastic sealing tube by pushing and squeezing, and pass through the elastic sealing tube to contact and immerse In the storage of non-solid conductive medium, it is inevitable that a small amount of "non-solid conductive medium" will adhere to the plug connector when it is pulled out. Repeated use for a long time will not only cause the "non-solid conductive medium" stored in the medium sealed box to be damaged. It will also cause pollution of utensils and the environment due to the long-term adhesion of a small amount of "non-solid conductive medium" by the plug connector, which will bring health and safety problems; The long-term repeated plugging and unplugging of the plug connector and the fatigue aging of the material itself lead to a decrease in sealing performance, which affects the sealed storage of "non-solid conductive media" in the medium sealing box, and reduces the safety of fully enclosed indirect conduction buckle-type safety sockets and supporting components. The functional quality of the plug; compared with the utility model patent of the application number 201921492623X and the invention patent technical scheme of the application number 2019108491659, the special structure and plugging method of the socket and plug not only keep the conductive parts in the whole process of plugging or pulling out without exposure. Completely wrapped and closed, it can be used in a humid and watery environment, and after the plug is pulled out, the live parts are protected by multiple insulations, and the connection between the socket and the plug is always in a power-off state, but the medium conduction in this technical solution The device still has certain defects; the present invention further optimizes the technical scheme of the reference document, and innovatively designs a fully enclosed indirect conduction device, which has greater advantages in safety, reliability and practicality
