The cover body 1G includes a base 1 and a top plate 12 which can be closed correspondingly. The base u has—a recessed groove / 11 ′ from its top surface and a shaft post u that is set upright at the center of the receiving groove ⑴. The receptacle ill has two open ends 112. The top cover 12 is roughly 3 plates. It has two indentations 121, which are recessed downwards from two opposite sides of the top surface. The top cover 12 corresponds to the manufacturing method of covering the base u. The joint between 12 and the base u is coated and bonded with iron core glue, and it is difficult to bond the one component into one. '4 wire 11 13 has a winding portion 131 which is formed by a long flat wire and a predetermined number of turns along a 20-to-fiber axis f, and two are respectively formed by the winding, and 131 ends outward.

As shown in the first figure, the outer ends of the two extensions 13 2 can be attached to the top cover 12 and bent upwards as required. The two grooves 5 121 are inside. In the manufacturing process of the above-mentioned conventional inductance element, in addition to the glue bonding processing performed on the base 11 and the top cover 12 of the casing body 10, it will cause its operation to be more troublesome, which is not conducive to mass production and increase costs. The installation structure in the receiving groove lu of the base 11 is because the coil 13 is accommodated between the base 11 and the top cover 12 in a 10-fit manner. There will inevitably be a gap, and the open ends U2 on both sides are an unavoidable magnetic permeability. Due to the gap, in addition to being prone to vibration and voice, it will cause large magnetic losses, and the quality factor (Q value) of the inductor will decrease. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an inductor element and a method for manufacturing the same, which have no gap between the cover and the coil and are convenient for mass production. Therefore, the inductor 7G manufactured by the method for manufacturing an inductive element according to the present invention has a coil and a covering body covered on the outside of the coil. 20 < The coil has a predetermined winding bent by a long wire The coiled portion counted and two extending portions respectively extending outward from the two ends of the coiled portion.

This design is to respond to the fact that the two extension portions 212 of the coil 21 are extended in a high and low level when the coil 21 is straddled. The upper mold 4 is a long sheet-like plate body which can be correspondingly covered with the aforementioned lower mold 3, and has a laterally extending upper base wall 41, and most of the adjacent grounds are connected by the lower base 8 200423162., ... ........ f 玖, :: Description of the invention, (5) A long box-shaped upper surrounding wall 42 which extends from the bottom surface of one of the walls 41 to the same body.

Each upper wall 42 has parallel front and rear wall sections 421 and 422, and two side wall sections 423 connected between the two ends of the front and rear wall sections 421 and 422. The upper wall 42 and the upper base wall 41 collectively defines an upper mold cavity 43 with an opening facing downward, and the shape of the upper surrounding wall 42 is a complementary shape corresponding to that of the lower surrounding wall 31 of the aforementioned lower mold 3, that is, These side wall sections 423 have the same degree of protrusion as the front wall section 421, and only the degree of protrusion of the rear wall section 422 is small. 10 As shown in the sixth figure, when the base 24 and the coil 21 are placed on the lower surrounding walls 32 of the aforementioned lower mold 3, the upper mold 4 can then be correspondingly covered on the top surface of the lower mold 3, and at this time borrowed The upper surrounding walls 42 of the mold 4 are tightly pressed against the lower surrounding walls 32 of the lower mold 3, respectively, and the two extension portions 212 of each coil 21 are clamped by using a jig (not shown). Positioned between the uranium wall sections 421, 321 and the rear wall sections 422, 322 of the corresponding 15 upper and lower surrounding walls 42, 32. At this time, the upper and lower molds 4 are in each of the upper and lower surrounding walls 4 夂 ^ Between them, a container space 5 defined by the communication between the upper and lower mold cavities 43 and 33 is defined together. The base 24 and the coil 21 are accommodated in the lower end of the container space 5. 20 As shown in the seventh figure, after each base 24 and the coil 21 are accommodated and positioned between the upper and lower molds 4 and 3, a fluid coating fluid made of iron alloy powder is then injected and formed by metal injection. In this way, the injection hole 411 of the upper mold 4 is injected into and fills the upper end of the containing space 5 to form a solid junction coating layer 23 covering the base 24 and the coil 21 by condensation. Covered here 200423162 发明, description of the invention (6) The fluid can be made of ferroalloy powder plus a solvent to aid flow and some cementation: 丨: made by these injection holes 411 into the upper and lower mold 4, 3 The volume is within% ° 卩, and the bifurcation fills the base 24 and the winding portion 1 so that the winding portion 211 of each base 24 and the coil 21 is filled with the solidified coating layer 23 which is condensed into a solid afterwards. And then combined into one. ίο 15 20 The connector is even more, and it can optionally be used to bake these integrated bases%, the coil 21 and the junction layer 23, so that the junction layer 23 is hardened and shaped, so that the desired inductance element 2 is made, and In the manufactured inductor element 2, the layer 23 occupies only a small part of the overall coating 22. In this embodiment, the volume of the composite layer 23 accounts for approximately the entire coating 22. The volume of the T base 24 occupies about 70% to 80% of the overall covering body 22, so the covering layer 23 only takes up a small part of the volume of the covering body 22 here. η is also 'worthy-mentioning that' the maternity made by the manufacturing method of this embodiment: + 2, the base 24 and the junction layer 23 can be used with different characteristics ... so that the inductance element 2 can meet the needs of different operating characteristics, Not limited by a single material condition, the effect of manufacturing a composite material type material ™ can be found in the new patent case of “Composite Inductor” No. 493790 issued by the inventor of this case. If you need it, you can go online ... If I will, it will be fixed by the two stoppers 6 preset on the guard machine (see === the two extensions 212 at the end of the coil 21 are blocked, so that subsequent operations will be injected During the cladding of the 2nd layer 212 army club, it is necessary to prevent the coil 21bis from extending and shifting forward and backward due to the influence of the flow pushing of the cover. 10 200423162 发明, Description of the invention (7) :: 'In addition, this implementation The ends of the two extensions 212 of the inductive element 2 made in the example can be separately bent and added with jade, and folded up to cover the top surface of the covering body 22, and the folded state is the same as that of the aforementioned first section. The two pictures are the same as shown in the figure. 4 The bottom surface of the upper substrate 41 is provided with a projecting downward portion, so that a corresponding groove is formed on the top surface of the covering body 22, which is not shown in the drawings. Ίο 15 According to the above manufacturing method of the conventional yoke example, In the manufacturing process, it is really unnecessary to perform the assembling operation of the bonding process performed by the conventional method, so that the manufacturing cost can be reduced and mass production is facilitated. Moreover, the manufactured inductor element 2 has a covering layer 22 formed by a junction layer. 23 and the base 24 cover the winding portion 211 of the coil 21 without a gap, and there is no gap between the winding portion 211 and the covering body 22, so it can avoid generating vibration and noise, reduce magnetic loss, and increase the Q of the inductance. In the manufacturing process, the coil 21 can also be stably positioned so that the distance from the inner wall of the mold is sufficiently separated and fixed to ensure the regular thickness of the magnet guide (the cover 22). As shown in Figure 8 It is shown that the coil 21 used in the manufacturing of the 7L inductor according to the manufacturing method of the second embodiment of the present invention is different from the previous embodiment. The coil 21 is formed by bending a long round wire, and the coil 21 has a A long round line A winding portion 211 formed by bending a wire into a predetermined number of turns, two extension portions 212 extending outward from both ends of the winding portion 211, and two extending in the same direction downward from the ends of the extension portions 212, respectively.

There are side positioning grooves 326 and 327 extending from the lower positioning grooves 324 and 325 to 11 20/200423162 respectively. (8) The side positioning grooves 326 and 327 of the lower i are extended so that the two bent portions 213 of the coil 21 can face each other and abut the two. The side positioning grooves 326 and 327 can further ensure the vertical stable state of the central axis of the coil 21. When the bases 24 and 5 coils 21 are placed on the lower surrounding walls 32 of the aforementioned lower mold 3, the upper mold 4 can then be correspondingly covered on the top surface of the lower mold 3, that is, as shown in the tenth figure, borrowing The upper surrounding walls 42 of the mold 4 are closely abutted on the lower surrounding walls 32 of the lower branch 3, respectively, and the two extension portions 212 of each coil 21 are clamped and positioned at the corresponding upper and lower surrounding walls 42 respectively. 32, between the front wall sections 421, 321 and the rear wall sections 422, 322, the base 24 is accommodated in the lower end of the accommodation space 5 like the wire 10 circle 21. As shown in the eleventh figure, after each base 24 and the coil 21 are accommodated and positioned between the upper and lower molds 4 and 3, the flow-covering fluid made of iron alloy powder is then transferred from the upper mold 4 The injection hole 411 penetrates and fills the upper end of the accommodating space 5, and forms a solid junction coating layer 23 covering the base 24 and the coil 21 15 by condensation. Summarizing the above, the manufacturing method of the present invention covers the base 24 and the top of the coil 21 with a body coating layer 23 made of iron alloy powder, so that the integrally formed covering body 22 and the coil 21 are not formed. There will be a gap, which can effectively improve the quality of the manufactured inductor element, so it can indeed achieve the purpose of 20 < invention.
