INSTRUCTIONS: [Technical Field] The present invention relates to a terminal and a coated insulating layer structure thereof, and more particularly to a terminal of a conductive plug and an insulating structure for protecting a user from accidental contact. [Prior Art] Ο 〇 General daily life and industrial operation 'Electric appliances or electric wares, the source of electric power for AC, mainly by the use of Wei plugs and brewing to conduct electricity to electrical appliances or electrical appliances. The wire plug is mainly provided with two terminals or another ground terminal. The overall manufacture of the wire plug 'mainly uses the terminal stabilizer on an inner frame', and after the inner frame is smashed, the terminal-part and the plug are: externally; injection-formed, and (4) sub-service-partially Engaged with the socket and used for electrical conduction. However, the portion of the bare iij that is joined to the socket is easily exposed, and the user is at risk of electric shock. Therefore, many countries or regions stipulate the bare portion of the terminal to a segment of the insulating layer to prevent use. The danger of electric shock. -Reading a picture (taking a circular terminal as an example), the prior art - the terminal (1) the dummy layer is covered (four) Huai Di - «the terminal is not yet included Wei Weiqiu, the terminal (1) is designed to be straight from top to bottom . The problem with silk is that, under the rule of making a plug, in order to consider the tolerance of the shape of the shot, try to set the terminal = external control to be smaller, so that the fitting is ordered, and the plastic material has a relatively large 2 pass. The coating path is convenient for the production operation, but if the outer diameter of the terminal (1) is set, the rigidity of the metal of the terminal (1) is relatively insufficient. Therefore, it is difficult to ride the inspection under the safety specification of the electrical plug. On the other hand, if the outer diameter of the terminal (1) of the 20092540 is to be maintained, the thickness standard of the insulating layer is relatively lowered, but this thickness reduction causes difficulty in forming the injection operation. That is, it is easy to produce a defect in the quality of the lack of glue at the end of the plastic filling filling, that is, the metal of the terminal (1) is exposed due to the excessive thickness of the insulating layer, and the quality thief of Wei Wei is lost. Referring to the second and second B-pictures (for example, a flat solid terminal), the first technique is substantially the same as the prior art, and the appearance is slightly different. And the second A picture and the second picture of the second end of the A), the outer rim is also a flat from top to bottom. The correspondingly coated insulating layer (11) is also flat from top to bottom, and thus has the same problem as the prior art one described above. SUMMARY OF THE INVENTION In view of the problems of the prior art for the insulating layer coating of the terminal, the present invention considers that there should be a balance between the satisfaction of the insulating layer coating and the balance between the rigidity of the terminal, and at the same time, the peripheral portion of the terminal body is small. However, after the insulating layer is coated, the appearance alkali is flat, and the (4) sub-body is sufficiently conformable in the part that needs to be tested for intensiveness, and the seam meets the safety specifications, and thus has the design of the present invention. The technical means used in the prior art to solve the previous problems is mainly to design a terminal and its covered insulating layer structure, including a terminal, the outer edge of the terminal is provided with an insulating layer, and the invention mainly lies in the section of the terminal covering the insulating layer The portion is formed from the back to the front to a convergent shape, and the thickness of the insulating layer covered by the outer edge of the terminal is relatively thicker from the back to the front to make the terminal form a flat shape after covering the insulating layer. In addition, the amount can be _ in various county Xuan, such as solid cylindrical 200926540, solid flat, hollow cylindrical, hollow flat terminal. [Embodiment] The following is a more in-depth understanding of the present invention by means of _, 朗本(4), narration and reality. EDGE: The present invention relates to a kind of terminal (2) and its coating, and the third _ saki solid 敎 solution (2) is a detailed example 〇 j. The body of the terminal (2) is divided by the rear line scale: (before the front of the head of the hairpin, = the position of the line is made to be #, then the insertion section of the socket is a line part ( 21): -2=4 her, _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ M. A body segment (23): == Insulation layer (24) 'The insulation layer (24) can be used with the inner frame (3) as a slap in the face of "users accidentally touched as a protection against electric shock. The segment of the extracorporeal circle = _24) is formed from the back to the front to a wide extent, and the outer diameter is formed from the back to the front from the largest to the smallest. And the insulating layer (24) covered by the terminal (2) is gradually thicker from the back to the front, so as to form a straight line with the terminal (2) = shape thief's * 阙 阙 (2) (as shown in the fifth figure). 7 200926540 One insertion section (25): As a section that can be inserted into the socket. In addition to the solid cylindrical shape, the terminal of the present invention may have other terminal shapes as an embodiment, such as a solid flat shape, a hollow cylindrical shape, a hollow flat shape, or the like, and even a terminal of other shapes. The sixth A diagram and the sixth B diagram are exemplified by the solid flat terminal (2A), and the terminal (2A) further includes a line portion (21A) and a neck portion (22A) from the rear to the front. a body segment (23A) and an insertion segment (25A), and an end insulator (2A) body segment (23A) is covered with an insulating layer (24A) (see the seventh and seventh panels for the insulating layer). Show). The body section (23A) of the terminal (2A) has an outer contour which is formed from a wide rear to a convergent shape. And the insulating layer (24A) covered by the outer edge of the terminal (2A) is gradually thicker from the back to the front to form a complementary and corresponding shape with the shape of the terminal (2A), so that the terminal (2A) is packaged. After the insulating layer (24A) is covered, a flat shape is formed (as shown in FIGS. 7A and 7b). 8A is a front view of a coated insulating layer according to another embodiment of the present invention. SI8B is a side view of a coated insulating layer of the present invention. The ninth embodiment of the present invention is combined with an inner frame. And a plan view of the appearance of the covered insulating layer.
