Description

Ultra-thin wire plug

technical field

The invention relates to an electric wire plug, in particular to an ultra-thin electric wire plug.

Background technique

Existing wire plugs all have relatively large thickness. Even if they are inserted into the best socket flush with the wall, the thickness will still be fully exposed outside the wall. This prominently protruding socket outside the wall is both It is unsightly, occupies indoor space, hinders people's activities, and especially cannot make furniture close to the wall. When moving or placing furniture, it is very easy to be bumped by furniture, causing unnecessary safety hazards or economic losses.

Contents of the invention

The object of the present invention is to overcome the above-mentioned defects of the prior art, and provide an ultra-thin plug which can significantly reduce the occupied space.

In order to achieve the above object, the ultra-thin electric wire plug of the present invention includes a plug base and a wire and a plug terminal which are fixedly mounted on the plug base and connected to each other; Leading out horizontally; one or two symmetrical long-strip notches or long-strip openings with upper and lower openings or two symmetrical long-strip notches on the outside are formed on one side of the plug base; the plug The base body is hinged with a lever-type end cover on the outer end wall of the elongated notch or elongated opening or elongated notch through the horizontal inner hinge shaft, and the outer end of the lever-type end cap is outside the horizontal inner hinge shaft through the horizontal outer hinge shaft. A horizontal ejector rod extending inward is hinged, and the inner end wall of the plug base is hinged at the inner end wall of the elongated notch or the elongated opening through a horizontal inner hinge shaft parallel to the aforementioned horizontal inner hinge axis to have an inner support protruding from the outer end. Rod, the outer end of the inner support rod is hinged with the inner end of the horizontal ejector rod through the horizontal outer hinge shaft parallel to the aforementioned transverse outer hinge axis, and the lever type end cover, the lateral ejector rod, the inner support rod and the plug base are connected through two transverse inner hinge shafts and two transverse outer hinged shafts constitute a parallelogram form lever mechanism. With such a design, when the plug needs to be pulled out, it is only necessary to pull the end cover or the operating handle outward, and the horizontal ejector rod can be ejected toward the socket surface, and because the two inner hinge shafts and the two outer The hinge axes are always located on the two upper and lower corners of the parallelogram respectively (or the lever-type end cap, transverse ejector rod, inner support rod and plug base are formed by two transverse inner hinge axes and two transverse outer hinge axes Parallelogram lever mechanism), the horizontal push rod is always flush with the socket surface and the bottom of the plug base, so the plug terminal is always perpendicular to the socket surface and the bottom of the plug base during the pulling out process, and there is always a parallel rod and the bottom of the plug base during ejection. The contact surface of the socket is balanced, and there will be no skew when ejected; the contact surface between the ejector rod and the socket surface is large, the handle is long, and the force is strong, no need for manual assistance. After adopting the above technical solution, the thickness of the plug can be made very thin, and it can be inserted into the wall socket close to the wall, occupying less space, thereby effectively preventing the furniture from bumping into the plug, and it is also convenient to close the furniture to the wall, unplug There is no need to use other hands to assist when pulling out, and the plug will not be skewed when pulling out, which is convenient for operation and reliable in performance.

As an optimization, the underside of the lever-type end cap is formed with a reinforcing rib equipped with a horizontal inner hinge shaft, and the reinforcing rib is then hinged to the elongated notch or elongated opening or elongated notch wall through the horizontal inner hinge shaft. Such design is convenient for manufacture and assembly.

As an optimization, the plug is a two-phase two-wire type, or a two-phase three-wire type, or a three-phase four-wire type. With such a design, the elastic force of the contact shrapnel of the two-phase two-wire or three-phase four-wire socket can be made very large, and the plug does not need to be pulled out too much force.

As an optimization, the plug base has a two-phase three-wire plug with a long slot or a long opening, and a ground wire plug terminal and a pair of parallel phase wire plug terminals are fixed under the plug base body. The wires are led out from the side of the phase line socket terminal of the plug base body, and a long strip notch or a long strip shape opening is opposite to the wire side, and is located between a pair of parallel ground wire plug terminals or the wires are drawn from the plug base body. One side of the ground wire plug-in terminal is led out, and a long strip notch or a long strip-shaped opening is opposite to the wire side, and is located between a pair of parallel phase line plug-in terminals. Designed in this way, it is convenient to choose and apply.

As an optimization, both the plug base body and the lever-type end cap are of thin-plate type. With such a design, the thin-plate structure can be made as thin as possible.

As an optimization, a finger pocket-type pit is formed under the end of the lever-type end cap. With such a design, the thin-plate end cover or the operating handle is more convenient to operate after the finger pit type pit is formed.

As an optimization, the lever-type end cap is composed of a middle base with a hinged shaft underneath and mutually symmetrical side wings hinged to both sides of the middle base.

As an optimization, a limiting mechanism that folds up the two wings is formed or equipped between the two wings and the middle base.

As an optimization, the upward folding angle of the two side wings ranges from 60 degrees to 90 degrees; the limiting mechanism is a limiting protrusion or rib.

That is: there is one or two symmetrical hinges in the middle of the lever-type end cover of the plug, through which the two sides of the lever-type end cover can be folded upwards to facilitate access to the plug. Between 60 degrees and 90 degrees.

After adopting the above technical solution, the thickness of the ultra-thin plug of the present invention can be made very thin, and when inserted into the wall socket, it can be close to the wall and occupy less space, thereby effectively preventing furniture from bumping into the plug, and can also conveniently put the furniture Close to the wall; and: using a parallelogram lever mechanism, when ejecting, there is always a horizontal ejector rod in contact with the socket surface, balanced contact, when ejecting, there will be no skewing; the contact surface between the lateral ejector rod and the socket surface is large, and the handle is long , the strength is strong, no need for manual assistance; the end cover or the operating handle covers the plug base and can also protect the plug base and the electrical connection parts below; it is easy to operate, reliable in performance, strong in practicability, and can easily and safely pull out the plug. .
