Description of the Invention: [Technical Field] The present invention relates to a structural improvement of a plug conductive blade, and more particularly to a conductive blade which can save processing steps and reduce occupation length. [Prior Art] According to the plug, in order to be electrically connected to the socket, the front end surface or the bottom surface of the main body protrudes from two or three predetermined metal pieces (rods) of a predetermined type, which is commonly called a conductive blade. The conductive blade has many forms and specifications, and the most commonly used one is the flat-shaped conductive blade with a solid blade thickness of i5min as shown in the second figure (20). As shown in the first figure, the upper surface (12) is milled into a thinner thickness (t2) on a metal plate (11) having a thickness (tl) of 1.5 mm, which can be used in subsequent stamping processes. In the process of bending, it is necessary to add a thinning process in the process, which not only increases working hours but also wastes materials. Further, as shown in the second figure, since the conventional conductive blade (2〇) is used to remove the blade body (21), it is required to be formed by a thin upper surface (12) to form a u-shaped body (22). The U-shaped body (22) covers the core wire (31) of the electric wire (30) (shown in the third figure) because the coated U-shaped body has a certain length and width dimension, so that the adjacent two blade bodies are formed during stamping. Excessive waste spacing (dl) is wasted between (21). However, the amount of metal materials stamped off is considerable, especially the recent price of copper metal, which increases the cost of waste. Furthermore, as shown in the second and third figures, the conventional conductive blade (2〇) includes the length (L2) of the u-shaped body (22) in addition to the length (L1) of the blade body (21). And the length (L3) of the connection end of the core wire (3丨), and the lengths 1301004 (L1) to (L3) of the three segments are all on the same axis (XX), so that the pressing structure of the entire conductive blade becomes very Long and more space, not conducive to the design of the plug. More importantly, as shown in the fourth figure, the U-shaped body (22) is stamped into a bent body (221) which is pressed against each other by both sides, thereby wrapping the core wire (31). Form an electrical connection. However, it is checked that the open-type bending 砥 depends on the processing method of covering the core wire (31), and the stability and accuracy thereof are poor, especially the two mutually bent bending bodies (221) are easy to form a dome effect with each other. However, it is not easy to densely cover the core wire (31), so it is often used for a small current, and when a high-current electrical connection is used, a tubular squeezing structure is often used. The reason is that overcoming the problems and missing problems is the subject of the invention. SUMMARY OF THE INVENTION The main object of the present invention is to provide a plug-in conductive blade pressing structure which saves processing steps, which has the advantages of saving processing process and reducing the length of the inner section. Still another object of the present invention is to provide a plug-in conductive blade pressing structure that saves processing steps, which has a waste of metal material saving, thereby improving the cost of the plug. A further object of the present invention is to provide a conductive blade pressing structure for a plug which saves the processing process, which has the characteristics of being firmly pressed against the core wire, and thus can be applied to a high-current electrical connection and can improve the safety of the plug. Efficacy. In order to achieve the above object, the technical means adopted by the present invention comprises: a conductive blade having a flat elongated body and defining a section electrically connectable to the power supply socket, and a wire connectable a section, and a flat surface of the inner section is integrally formed with a flat elongated body integrally formed with a 1301004 through hole and a plane perpendicular to the convex ring body; and an electric wire, the front part of the core line is placed therethrough Inside the hole, and the convex ring body compresses the tight beam and electrically engages the conductive blade. [Embodiment] First, referring to the fifth to eighth embodiments, a preferred embodiment of the present invention comprises: a conductive blade (40) integrally stamped and formed of a metal plate having a thickness of 1.5 mm, the metal plate It includes materials such as brass or red copper, which are excellent in electrical conductivity and ductility. The design of this conductive blade (4〇) focuses on the structure of one-time stamping. It is not necessary to use milling machine for milling and secondary bending. The processing program, in order to achieve this effect, the conductive blade (4〇) has a flat long body, the length of which is (L1), and defines a region that can be electrically connected to the power supply jack (not shown). a segment (41), and an inner segment (42) connectable to the wire (30) (shown in Figure 9), and a flat elongated body on the flat surface of the inner region (42) The integral stamping is formed with a perforated (431) and a planar vertical convex ring body (43). Moreover, as shown in the sixth figure, the inner diameter of the through hole (431) includes a contraction surface (the 2), so that the core wire (3丨) of the electric wire (3〇) is penetrated; when the core wire (3丨) arrives After the through hole (431) is preliminarily pressed, the jig is used to perform a tight work on the outer periphery of the convex ring body (43), and as shown in the seventh and eighth figures, a concave is formed on the convex ring body (43). The compression surface (433) of the perforation (431) is inserted. The biggest difference between the pressing structure and the conventional pressing structure is that the conventional pressing structure is composed of a u-shaped body bending, and cannot completely tighten the coated core wire (31), and the convexity of the present invention is reflected. The ring body (43) is a seamless structure integrally formed with the conductive blade. When it forms a compression surface (433) and tightly binds the core wire (31) without any joints or gaps, it is firmly tightened to the core wire. (3 1 ), not only is not easy to relax, and the electrical connection is good, and the conductivity can be improved by 1301004. In addition to the characteristics of the aforementioned pressing structure being stable, since the necessary width of the U-shaped body is not used, the distance (d2) between the two conductive blades (40) of the press forming can be very small as shown in the fifth figure. Therefore, it saves a lot of washed metal materials. Moreover, the length of the conductive blade (40) is only (L1), and there is no (L2) length of the conventional U-shaped body (22) shown in the third figure, because this part The present invention has been replaced by the convex ring body (43). Therefore, the present invention can directly reduce the cost of the conductive blade (40), which is economical. Further, in addition to the foregoing structural stability and material saving effect, the present invention has another feature as shown in the ninth figure, that is, the electric wire (30) is not in the same axis as the conductive blade (40) as usual (XX). , but the Y axis perpendicular to the X axis, that is, the length (L3) of the core wire (31) is on the side of the conductive blade (40), not at the upper end thereof, and the structure includes two branches. When the opposing pairs are called a set of positive and negative conductive edge types, they are very suitable for the conductive blade of the very popular flat plug (50) shown in the tenth figure, the outer section of the conductive blade (40) (41) is vertically protruded from the bottom surface of the flat plug (50), and the inner section (42) is fixed in the plug body, and is formed as a convex ring body (43) joined to the electric wire (30). Formed on the side of the inner section (42), so the thickness (T) of the flat plug (50) can be very thin, about 10 mm or so, so the present invention also has no space to reduce the thickness of the plug. The effect is enhanced. Of course, the structure of the conductive blade (40) of the present invention is not limited to the use of a thin plug and a straight plug, and has the same effect of reducing the height of the plug. Other electrical connectors are also applicable, and are not described herein.
