Plug-socket in gap-free fit

Abstract

The invention discloses a plug-socket in gap-free fit, comprising a plug and a socket. The plug mainly comprises a plug body and a plug electrode fixed to the plug body. The socket comprises a box-type socket body and a jack arranged on the socket body. A contact piece of the plug electrode is arranged in the jack of the socket. The plug electrode is arranged into a conical convex body, the contact piece is arranged into a conical concave body matched with the conical convex body of the plug electrode, and the cone angle of the conical convex body and the cone angle of the conical concave body are 0.2-15 degrees. The plug-socket is simple in structure and safe and reliable. By adopting the cone design, plugging and pulling are more convenient and labor-saving compared with the currently used X-type, Y-type and 'Hui'-shaped (two squares sleeved together) structures, and the phenomenon of point discharge is avoided. The cone angle of the conical convex body and the cone angle of the conical concave body are designed into 0.2-15 degree, which can eliminate power consumption caused by gap discharge. The plug is safer and more reliable than the existing sheet plug, and the energy saving effect is remarkable.

Description

technical field [0001] The invention relates to a plug and socket with no clearance fit. Background technique [0002] With the development of society and the progress of human beings, the application of electricity and electrical appliances has already entered thousands of households. When people use electricity, they find that the two wires of the plug and the socket are easy to heat while the middle wire is not hot. The same current and voltage produce this phenomenon. The reason is that the tip discharge of the plug and the gap between the plug and the socket continue to increase, resulting in gap discharge, and the discharge will consume a large amount of electric energy, causing heat to be generated at both ends of the connecting line between the electrical appliance and the power supply. The greater the power, the greater the heat. Thereby consume electric energy, reduce the service life of electric appliance, also make electric appliance have certain potential safety...

[0002] With the development of society and the progress of human beings, the application of electricity and electrical appliances has already entered thousands of households. When people use electricity, they find that the wires at both ends of the plug and socket tend to heat up while the middle wire is not hot. This phenomenon occurs with the same current and voltage. The reason is that the tip discharge of the plug and the gap between the plug and the socket continue to increase, resulting in gap discharge, and the discharge will consume a large amount of electric energy, causing heat to be generated at both ends of the connecting line between the electrical appliance and the power supply. The greater the power, the greater the heat. Thereby consuming electric energy, reducing the service life of electrical appliances, and making electrical appliances have certain safety hazards when they are in use

The charger of the mobile phone is easy to loose the socket due to long-term use, resulting in poor contact and unable to charge, which will also reduce the service life of the mobile phone and the charger.
