Description of the invention: [Technical field to which the invention pertains] Used in ΓΓ: relates to a coil device, in particular to a small, low-thickness type inductor and a line for transforming a surface wave. Prior Art A-type electronic devices have been developed toward miniaturization and thinning, and are required to be smaller and lower in thickness than components on specialized machines. =: The coil f of the inductor and the transformer on the circuit board of the sub-machine is generally: the base of the synthetic resin made of the external connection terminal is wound around the core of the coil, and there is no resistance. The method of pressing the specified line (4) with /' corresponding to the requirements of miniaturization and low thickness is mainly to use an adhesive to directly connect the metal terminal to the core. However, when an adhesive is used to directly connect the metal terminal to the core, it is a sintered body of a core ferrous salt or the like, so that it is difficult to obtain a high strength and then a strong metal is used. Metal materials such as copper alloys and irons are plated with metals such as gold, silver or tin to ensure corrosion resistance of the terminals and properties of the solder. The end of the electric mine! The surface smoothness is high' and the high smoothness will lower the metal terminal's connection = degree #者' in the formation of a tin-plated or solder electric ore, etc. The heat attached to the coating causes softening or dissolution of the electrodemine layer so that the adhesive surface is also softened, and as a result, the subsequent strength of the metal terminal is further reduced. The #目目 causes the adhesion of the solder: "The second is the increase in the number of ships used in recent years," which makes the problem even more serious. For this reason, 1254325 has many ideas for improving the strength of the core and the metal terminal. (T 丄u - du 3 〇3 4), it is disclosed that a recess is formed on the rear surface of the terminal of the core, and an adhesive insertion structure is provided on the terminal corresponding to the recess, and the terminal can be used. The technique of fixing the core and the terminal is fixed by the two sides, and the technique of fixing the core and the terminal is described in the patent document 2 (Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. There is a star-shaped uneven portion and a surface area-increasing structure in which a groove or the like is provided on the bottom surface of the core, and the core and the terminal cannot be peeled off even if the solder heat is used. Patent Document 3 (Japanese Patent Laid-Open No. 1) L_ 2 8 3 8 In the No. 7 bulletin, it is disclosed that the core mounting portion of the lead frame having the outer layer of the soldering layer (thickness of the copper layer or the solder plating) is not provided. The material adhesion preventing layer is used to improve the strength of the adhesive. It is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. The convexity, the edge 'the technology of the core setting portion and the flange and the core to improve the strength. However, all of the above techniques require processing of the metal terminal and the core shape to improve the bonding strength', so there is a problem that the cost rises. It does not improve the basic poor strength of the material of the core and metal terminals composed of ferrous salts, and the subsequent strength is limited. ^In addition, the miniaturization and thinning of components make the heat dissipation surface of the coil device There is a problem, that is to say, 'When the component with the same heat quantity is I254325, the external surface area is also reduced, which will reduce the heat dissipation. Therefore, when designing the coil device, it is necessary to consider the heat generation control and heat dissipation. SUMMARY OF THE INVENTION The main object of the present invention is to provide an improved core and metal terminal that is subsequently attached. In the case of the above-mentioned invention, the present invention provides a coil device which is excellent in heat dissipation. The coil device of the present invention includes a core, a coil, a S-stage, and a terminal. The core includes a winding portion, a port connection σ®, and a joint surface ′. The coil portion is wound with a coil; The synthetic resin is composed of a core joint portion and a terminal joint portion, and the terminal portion is composed of a metal plate 5 including a core joint portion and a coil joint portion, and is formed by a terminal joint portion formed on the base portion. The base is coupled; the core joint formed on the base and the core joint formed on the base are respectively connected to the base of the core: the surface and the terminal joint surface; The coil system is connected to a coil connecting portion formed on the aforementioned terminal. In the coil device described above, the base is made of synthetic resin and includes a core joint portion and a terminal joint portion. The synthetic resin is equivalent to the adhesion of the adhesive to the core, and the selection range of the adhesive and the synthetic resin material is large. By using a suitable combination of the synthetic resin material and the adhesive, the alloy and the metal can be compared with the metal. Obtain a greater 1254325 followed by strength. The terminal is formed of a metal plate including a core joint portion and a coil connecting portion, and is coupled to the 3 base plate by a terminal joint portion formed on the base plate. The core joint portion formed on the base 5 and the core joint portion formed on the terminal are respectively surface-engaged with the base joint surface of the core and the terminal joint surface. With such a configuration, the core joint portion formed on the terminal is joined to the base of the synthetic resin having the strength 咼 with respect to the metal terminal having the lower core strength, and the core joint portion formed on the base is together Then, on the core, the overall strength of the terminal is higher from the perspective of the coil device as a whole. The hot spring garden is formed by connecting the aforementioned terminals to the coil connecting portions on the above-mentioned green ring device. The terminal is bonded to the terminal interface of the core. With such a configuration, the heat dissipation performance of the coil device can be effectively improved. The heat generated in the coil device is due to the heat generated by the copper loss of the coil and the eddy current loss of the core and the heat loss caused by the iron loss. This heat can be dissipated via the terminal in contact with the core surface, and the coil is connected via the coil. The heat is removed from the terminals and terminals. Therefore, it is possible to set the heat dissipation performance of the coil u by considering the contact area with respect to the terminal of the core, the sectional area of the terminal, and the surface area of the terminal. ,山子:;:::' The invention can use a synthetic resin to improve the core and the metal and the subsequent bad connection. The terminal of the coil device as a whole: "Therefore, it can provide a coil device with excellent heat dissipation performance. In the case of the body, the terminal joint portion of the terminal 'the cookware is formed as a tooth hole. If the synthetic resin of the terminal joint portion 1254325 is buried in the through hole, the terminal and the base can be made. The combination of the platform is more stable, and the strength of the core and the terminal is improved. Although the contact area of the core joint formed on the terminal with respect to the core surface is larger, it is more helpful for the heat dissipation performance, but when it is too large, The surface of the core joint formed on the base is relatively small with respect to the surface contact surface of the core, and the 'will also narrow the interval between adjacent terminals. The interval between the materials is narrowed. The lead frame forming right armor used in the manufacture of the terminal is a combination of the fate and the amp , 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 Weighing =: 3 The problem of poor insulation occurs. Therefore, the adjacent stalks are separated by n η .n. The sigh is placed above 0·5 mm, and the better is better than 1 mm. The core joint on the base is in contact with the surface of the core, and the strength of the fabric is higher. For this reason, the core base joint surface, the second is better than the adjacent terminal spacing, and the core pair The direction of the center of the second Buyuan has more than 1/4 of the size of the outer edge: respectively. The above are all necessary for the terminal strength and heat dissipation performance of the present invention: a: # Bζ, 广, , , With reference to the drawings, the description of the leg from the leg is made. The figure attached to the figure θ - 疋 ' is merely an example. As described above, the present invention can be obtained by the present invention.
