Abstract

The invention discloses an IEC (Integrated Ethernet Chip) plug comprising a cylindrical shell, an inner conductor and an insulating part, wherein the insulating part is used for fixing the inner conductor into the cylindrical shell; the inner conductor comprises an inner conductor main body and elastic arm locks; each elastic arm lock consists of two parallelly-placed extending arms and elastic arm lock heads positioned on one ends of the two parallelly-placed extending arms; the extending arms are in the shapes of sheet-shaped strips, extend from both side ends of the inner conductor main body and are perpendicular to the flat surface of the flat-shaped inner conductor main body; the elastic arm lock heads are in the shapes of incurved arcs; the inner conductor main body positioned between the two extending arms is provided with elastic points, and the extending arms are positioned at both sides of the flat surface of the flat-shaped inner conductor main body, and the elastic points are positioned at the main body flat surface of the inner conductor; and a space for containing the extending arms of the inner conductor and the elastic points is retained in the insulating part. Compared with the traditional standard IEC plug, the IEC plug is reduced in half of the dimension, keeps the property unchanged, is convenient to realize industrial production due to the structure and has higher finished product ratio and greatly reduced material cost.

Description

The IEC plug

Technical field

The present invention relates to a kind of plug of IEC standard.

Background technology

At present, the IEC connector is usually used on the various electric equipments, and the external diameter of standard IEC plug is about 9.525mm.IEC plug outside commonly used is the tubular metal shell of both ends open, is inserted with the metal inner wire on the axis of enclosure interior, is fixed on the housing axis through insulating part, and the metal inner wire often adopts tubular structure.

Electric equipment products have more and more miniaturization, more and more thinner development trend now, the thickness that has even less than the diameter of full-sized IEC connector, and at this moment original IEC connector just seems too big.And the electric equipment products that have need mutual supporting use, between with the connection of IEC connector, the IEC connector of original standard large-sized can make matching used electric equipment products seem huger, and is exquisite inadequately attractive in appearance.But little as if directly the IEC connector of original structure being done, because the restriction of existing model technology is difficult to realization, when producing in batches, be difficult to ensure the quality of products, rate of finished products is lower.

Summary of the invention

The present invention seeks to: to the deficiency of prior art, a kind of IEC plug of miniaturization is provided, makes the size of IEC plug littler, property retention is constant, and its structure is convenient to commercial production.

Technical scheme of the present invention is: a kind of IEC plug; Comprise tubular shell, inner wire; With the insulating part that is used for inner wire is fixed on tubular shell; Said inner wire comprises inner wire main body and elasticity jig arm two parts, and the elasticity jig arm is made up of with the elastic clip arm head that is positioned at extension arm one end two extension arms of parallel placement; Said extension arm is strip in the form of sheets, stretch out from the two side ends of inner wire main body, and perpendicular to the inner wire main body plane of flat, said elastic clip arm head is aduncate camber line shape; Inner wire main body between two extension arms is provided with pop-off, and said extension arm is positioned at the both sides on inner wire main body plane, and pop-off is positioned on the inner wire main body plane; The extension arm of accommodating inner wire and the space of pop-off are left in said insulating part inside.

Further, the diameter of said tubular shell is 4.4mm.

Advantage of the present invention is: the size of this IEC plug is compared with prior standard IEC plug, and it is half that size reduces, but performance is unaffected, identical with existing standard IEC plug.The structure of this miniaturization IEC plug is convenient to commercial production and is realized that rate of finished products is higher, and material cost reduces greatly.

Embodiment

Embodiment: the IEC plug of present embodiment such as Fig. 1 be to shown in Figure 4, comprises tubular shell 1, the inner wire 3 of both ends open, inner hollow and be used for inner wire 3 is fixed on the insulating part 2 of tubular shell 1.Said inner wire 3 comprises inner wire main body 31 and elasticity jig arm two parts, and the elasticity jig arm is made up of with the elastic clip arm head 33 that is positioned at extension arm one end two extension arms 32 of parallel placement; Extension arm 32 stretches out from the two side ends of the inner wire main body 31 of flat; Strip in the form of sheets; And perpendicular to inner wire main body 31 planes, elastic clip arm head 33 is two aduncate camber line shapes, and the inner wire main body 31 between two extension arms 32 is provided with pop-off 34; Extension arm 32 is positioned at the both sides on inner wire main body 31 planes, and pop-off 34 is positioned on inner wire main body 31 planes.Said insulating part 2 is like Fig. 5 and shown in Figure 6, and the extension arm 32 of accommodating inner wire 3 and the space of pop-off 34 are left in inside, and the extension arm 32 of inner wire 3 is tightly snapped in the insulating part 2 with pop-off 34, and inner wire main body 31 is stretched out from the head end of insulating part 2.The outer surface of insulating part 2 is provided with a groove, and is inwardly recessed with the corresponding position of groove of insulating part 2 on tubular shell 1, and when making insulating part put into tubular shell, ability and tubular shell are closely fixing.Because present embodiment is simple in structure, compact, the tubular shell 1 of present embodiment can accomplish that the diameter at outside maximum gauge place is the size of 4.4mm.

When assembling this IEC plug, insulating part is inserted from the tubular shell afterbody, then the tail end of inner wire from insulating part inserted, and the top that makes the inner wire main body stretches out from the head of tubular shell, the pop-off of inner wire snaps in the receiving space of insulating part.The groove of insulating part outer surface just in time snaps in the recessed position of tubular shell.Then, on the head shell of tubular shell, get ready, make insulating part and tubular shell better fixing.

The above is merely the preferred embodiments of the present invention, can not limit the scope that the present invention implements with this, and all simple conversion of doing according to claim of the present invention and description all should still belong to the protection range that the present invention covers.
