Abstract

An improved walling plug comprises an external body, an internal body. The inner bottom of the shell-shaped external body, the opening of which is upward, is provided with a fixed base for extension of a positive conductive insert edge and a negative conductive insert edge or an earth wire while the back side is provided with an embedding groove for fixing the electric wire. The internal body is combined with the external body to form a plug shape and the external body is the fully high shape of the plug body and the outer side of the external body is provided with an internally condensed step surface. The internal body is in covering plate shape to embed in the opening of the external body to fix the external body, forming a shape that the external body coats the internal body. The utility model adopts the mutual and rapid combination of the external body and the internal body, makes the external body coat the internal body and has the effects of increasing the strength of the body and convenient installation. The drawing area of the external body forms an integral body with the fixed seat of the conductive insert edge, making the external body having stronger effect in the process of drawing. The walling plug adopts various colors of the external body and the internal body which can be exposed on the surface of the external body, so the whole body can show various modelling changes.

Description

Improved wall-attaching type plug

One, technical field

The utility model relates to a kind of appliance plug, relates in particular to that a kind of to have an assembling convenient, firmer during drawing, and make integral body can manifest the improved wall-attaching type plug of various variation in moulding.

Two, background technology

The plug of commonly using (1) as shown in Figure 1, it is equidirectional with body (12) that its conduction is inserted sword (11), makes body (12) vertically protrude out on the socket of wall, has the shortcoming that takes up room.So wall-attaching type plug as shown in Figure 2 arises at the historic moment then.The feature of this plug (2) is that this conduction is inserted sword (21) and body (22) is to be vertical configuration, makes when the slotting sword (21) of conduction inserts wall socket, and be to abut on the wall, have the advantage that does not take up space.Yet this wall-attaching type plug is to utilize the plastics ejaculation one-body molded, still, utilizes plastics to penetrate and electric wire (23) and the slotting sword (21) of conduction must be placed die for molding simultaneously.Its method for making is announced No. 196786 patent as Taiwan and is disclosed.But, utilize plastics to penetrate and electric wire (23) and the slotting sword (21) of conduction must be placed die for molding simultaneously.So, cause production efficiency low, cause to cost an arm and a leg, the more important thing is, the body (2) that utilizes plastic shaping be must with the soft plastic of electric wire (23) with material, therefore intensity is slightly poor, and after it is flattened on wall jack, as it will being extracted, because of the finger grip area too little rather difficult, therefore must add a draw ring (24) in addition, will conduct electricity slotting sword (21) for the finger hook and in jack, extract.Case before this type patent still has Taiwan the patent case such as to announce No. 306687 and announce No. 383929, and it all is to add a lug or jack-up bar at body, so as to plug is taken out.But general plug can produce high temperature when load, make header body slightly softening, and the above-mentioned prior art that adds the drawing structure; Certain that all pulling capacity is concentrated on header body a bit forms stress and concentrates, and softening plug adds wrecking that upper stress concentrates, and is very easy to cause the short circuit of plug inside or open circuit, and diminishes plug itself on the contrary, need be improved really.

As shown in Figure 3, commonly use the another kind of method for making of wall-attaching type plug, its header body (25) is to utilize upper and lower casing (251), (252) moulding separately earlier, after combination coats each element mutually then, utilizes high frequency welding or screw to make upper and lower casing combination all around.But, this header body (25) of utilizing upper and lower casing (251), (252) be combined into, its faying face (253) is half height and position at body, added that again lug (26) is articulated in therebetween, for drawing usefulness, make pulling capacity concentrate on the faying face of upper and lower casing (253), and header body (25) is split, thereby useful life is not long and the proportion of goods damageds are higher.

In addition, no matter aforementioned which kind of plug construction because of being subject to the basic structure of upper and lower casing, is therefore limited in the variation of color or body, can't show various variable shaping, also is slight scarce shaking.

Three, summary of the invention

Main purpose of the present utility model is, a kind of improved wall-attaching type plug is provided, and it utilizes the mutual Rapid Combination of inside and outside structure body, and makes outside body coat inner body, has the body intensity of increasing and assembles effect easily.

A purpose more of the present utility model is, a kind of improved wall-attaching type plug is provided, and its outside body drawing district inserts sword holder consubstantiality with conduction, firmer effect when making it have drawing.

Another purpose of the present utility model is, a kind of improved wall-attaching type plug is provided, and it utilizes inside and outside structure body different colours and the protruding structure surface that exposes outside of inner body energy, makes integral body can manifest various variation in moulding.

The purpose of this utility model is realized by following technical scheme.

A kind of improved wall-attaching type plug comprises: an outside body is to be opening housing shape up, and end is provided with the holder of inserting sword or having earth connection to stretch through for positive and negative conduction in it; Rear side is provided with the caulking groove for securing electric lines; One inner body is to constitute a plug form with the outside body combination; It is characterized in that described outside body is the overall height form of header body, and the cascaded surface that in outer side edges is provided with, contracts; Described inner body is to be the cover plate form, with in the opening that embeds outside body and make it be stationary state, forms the form that coats inner body with outside body.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid improved wall-attaching type plug, wherein inner body can utilize high frequency welding and outside body to be combined as a whole and fix.

Aforesaid improved wall-attaching type plug, wherein the side of outside body is provided with several blocking holes, and inner body is provided with an elastic extension sheet with respect to the blocking hole of outside body, the Extendible flake bottom forms the button can be nested in the blocking hole, with hook in the blocking hole and be fastened mutually.

Aforesaid improved wall-attaching type plug, wherein the root edge face of inner body is provided with several positioning convex column, and outside body is provided with the convex body in band post hole relatively at the interior end, upwards be locked in positioning convex column by screw by the convex body bottom.

The utility model utilizes the mutual Rapid Combination of inside and outside structure body, and make outside body coat inner body, have the body intensity of increasing and assemble effect easily, its outside body drawing district inserts sword holder consubstantiality with conduction, firmer effect when making it have drawing, it utilizes inside and outside structure body different colours and the protruding structure surface that exposes outside of inner body energy, makes integral body can manifest various variation in moulding.
