Description of the Invention: [Technical Field] The present invention relates to a plug plastic terminal, and more particularly to a plug for use in a power socket, and a plastic terminal thereof. [Prior Art] In general daily life and industrial operation, the use of electrical appliances or electrical appliances, the source of electrical power for alternating current is mainly to engage a socket with a wire plug and conduct current to electrical appliances or electrical appliances. Based on the safety of electricity, the current wire plugs have safety requirements in many countries. Therefore, the socket usually has a three-pole jack to provide three-pole (positive, negative and ground) terminals for plugging, and some countries Or the grounding terminal of the area does not have the configuration of the conductive grounding wire (that is, there is no metal conduction and riveting for the grounding terminal), and the plastic terminal is used as the place to replace the grounding terminal, and the grounding terminal can be inserted into the two-pole socket' Provide a record for inserting the ground terminal. Avoid the inadvertent paste of the original. __The Naxuan first inserted and used as a positive and negative energizing gate. Since the plastic terminal is different from the ground terminal of the original metal, it still has its own standardization, so many _ or regions still provide safety specifications for this _ axis as a specification. Among the various specifications, the main one is that when the plastic terminal and the plug n body are shot fine, the grip of the junk is covered and the stability is fixed, and since the outer edge of the petal terminal is smooth, the scratch is The force is not strong, and the test towel in the safety specification cannot be passed. At the same time, there are safety concerns in the use of the actual 5 201001814. Referring to the first to third figures, there is a prior art plug plastic terminal 'the plastic knee terminal (6) and an inner frame body (3) are injection molded into a body, and the terminal body of the plastic terminal (6) The inner frame body (5) is a part of the body injection molding, and is provided with a concave edge _ 'the combination of the terminal (6) ram body (3), which has a slightly stable and gripping money. However, since the terminal of the terminal (6) of the _ axle is trapped, the terminal body (6) of the terminal (6) is degraded in the cross-sectional area, so in the safety specification test: the under-roller test, because the terminal body (10) The strength is weakened' so it is easy to break. SUMMARY OF THE INVENTION The present inventors believe that there should be an improved structure of 'design intent' material - a plug plastic terminal, the plastic terminal can be placed into an inner frame And the inner frame body is injection molded into a body, mainly because the terminal body of the plastic terminal and the portion of the inner frame body-body injection molding are provided with a flange, and the main purpose is to make the plastic terminal and the gorge body Combined, it has a strong production of stable and grasping, and the firm grasping the branch ensures that the terminal section is degraded, and the mechanical strength is not degraded, and there is a better strength. The present invention is directed to the fact that the plug is a terminal and can be characterized by various embodiments. The flange phase is provided on the outer edge of the stator, and the flange may be provided on a partial outer edge of the terminal body. The two can be selected to achieve the foregoing objects. In addition, the present invention is further provided with a perforation in the terminal body of the plastic terminal at the position of the terminal and the singular body. When the plastic is allowed to be injection molded by perforation, the molten plastic material can enter the perforation, and when the plastic material is dried, there is a stronger grip for the plastic terminal, and the perforation is under a limited cross-sectional area. It does not detract from the mechanical strength of the plastic terminals required by the safety specifications. In addition, the flange of the present invention adjacent to the terminal body can form a chamfered or R-angled connection state to avoid stress concentration caused by the difference between the flange and the terminal body. The return line is a defect in the resistance to bending. According to the fact that the flange is buried inside the inner frame, and the general country is based on electrical safety, there is a safety requirement for the plug product. For example, in the hoisting test, 2 plastic terminals must withstand more than 25 minutes of gravity (can not fall off), so the added flange, the convex area (quantity) can make the plastic knee terminal firmly in the inner frame Meet the requirements of safety regulations. On the one hand, the invention can also pass the roller test on the safety gauge (that is, the invention is placed in the drum to check whether the plastic terminal is loose or broken according to the test specifications and the number of times), and the compressive strength and other mechanical strength requirements. The structure of the flange has a cut-off and a product that is far larger than the size of the scale safety, and the mechanical strength of the safety test such as the drum test and the compressive strength can be determined in the overall structure. [Embodiment] Hereinafter, the structure, characteristics, and embodiments of the present invention are assisted by the assistance of the drawings, and the examiner is responsible for the knowledge of the financial progress. 7 201001814 The present invention relates to a type of plug-in terminal, as shown in the sixth figure, which is a state of the finished product of the combination of the present invention, which comprises: '-inner frame body (1) 'The body (1) is pierced - the positive terminal (3) and the negative terminal (4) (assisted by the seventh figure), and is provided with a plastic terminal (2), because the positive terminal (3) and the negative terminal (4) and the case The subject matter is not directly _, and it is a prior art, and it is not described here. θ Please refer to the fourth figure, as shown in the fifth figure, the nano terminal (2) and the inner frame body (1) of the present invention can be injection molded into a body as shown in the sixth figure of FIG.
