Ablation-proof electric power plug with power line rotatable

Abstract

The invention provides an anti-ablative power plug whose power cord can rotate, which comprises a plug chassis, rotating upper covers and an anti-ablative electrode, wherein the rotating upper covers are connected together through a locked structure, the anti-ablative electrode is arranged on the plug chassis, a power cord horizontally penetrates to be connected with the anti-ablative electrode from conical holes on the lateral surfaces of the rotating upper covers, and a wedge-shaped strip is inserted on the inner ends of the conical holes to fix the power cord in the conical holes. Comparedwith the prior art, the invention has the advantages of reasonable design, simple structure, safety, reliability, convenient employment, easy assemblage and the like, the power cord not only can rotate along the direction where consumer equipment exists, but also a plug electrode and a socket electrode can excellently contact to prevent flashover and heating from ablating electrodes. The anti-ablative power plug can improve the security and the service span of the plug and the socket, and can reduce the power-off rate, and therefore, the anti-ablative power plug has excellent popularity and service values.

Description

1. Technical field [0001] The invention relates to an electrical product, in particular to an anti-ablation power plug on which the power cord can rotate left and right. 2. Background technology [0002] Power plugs are indispensable for various electrical equipment and various household appliances. The power cords of the three-pole power plugs and four-pole power plugs in the prior art are arranged vertically above the plug, and most of them are horizontally arranged on the side of the plug. The disadvantage is that when the power cord is perpendicular to the plug, whether it is connected to the power strip on the desktop or to the fixed power socket on the wall, the power cord always has to bend a 90° bend, due to the frequent movement or length of the power cord. Time bending will cause damage to the bent part of the plug, resulting in poor contact of the power plug and affecting the normal use of electrical equipment. At present, most of the power strips sold in the mar...

[0002] Power plugs are indispensable for various electrical equipment and various household appliances. The power cords of the three-pole power plugs and four-pole power plugs in the prior art are arranged vertically above the plug, and most of them are horizontally arranged on the side of the plug. The disadvantage is that when the power cord is perpendicular to the plug, whether it is connected to the power strip on the desktop or to the fixed power socket on the wall, the power cord always has to bend a 90° bend, due to the frequent movement or length of the power cord. Time bending will cause damage to the bent part of the plug, resulting in poor contact of the power plug, affecting the normal use of electrical equipment

At present, most of the power strips sold in the market are double rows, that is, the plug strips are equipped with two rows of power sockets, and the electrode jacks of the sockets are consistent. It must be reversed 180°, which will bring inconvenience to the user and also cause damage to the plug wire

In addition, the electrodes of the power plug of the prior art and the electrodes on the power socket often cause electric sparks due to poor contact due to the small contact area. After a long time, the power plug and the power socket will be burned out at the same time, which not only easily damages the electrical equipment, but also causes electric energy. The waste, and the replacement and maintenance are very troublesome. In the overall injection-molded power plug, because the welding between the power cord and the plug electrode is very troublesome, some manufacturers just wrap the plug electrode and the power cord before casting them in plastic. In this way, poor contact between the electrode and the power line is inevitable. It is inevitable that the plug and socket will burn out after a long time or the current is too high. This is also a potential hidden danger of a fire accident. There is no good solution yet.
