Description of the invention (丨) The present invention relates to a choke structure, and in particular to a surface-adhesive choke structure. (Please read the note on the back? Matters before filling out this page.) Due to the advancement and demand of electronic technology, all kinds of electronic related products have been developed to be light, thin, short and small. Taking a notebook computer as an example, the thickness of its LCD panel has been reduced from 8mm to 7mm a few years ago, 6mm to the nearest 5mm. For booster chokes, thickness and weight, which are often used in thin control panels, The demand is even lower. However, the conventional choke coil still has some problems in reducing the thickness and weight, as described below. Please refer to FIG. 1, which is a flowchart of a conventional choke process. Please refer to FIG. 2 to FIG. 5 at the same time, which are sectional views of each step before the test procedure of the conventional choke process. The conventional choke manufacturing process includes the following steps: First, please refer to Fig. 2 to provide an iron core (such as 112 in Fig. 1). The iron core 110 is slightly cylindrical and the side is slightly I-shaped. The material is The ferrous iron structure has an iron core 110 with an axial center portion 110a and two circular plate surface portions 110b. Then, a winding process is performed (such as 114 in FIG. 1), and a winding wire 102 is wound along the surface of the core portion 110 a of the iron core 110. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, please refer to Figure 3. On the other hand, the metal shell and terminals are processed (such as 116 in Figure 1). After the metal shell and terminals are processed, they are inserted. In the iron core step (such as 118 in FIG. 1), the metal shell 100 is sleeved into the iron core 110 completed by winding. Please refer to Figure 6 and Figure 7 at the same time, where Figure 6 is the top view of Figure 3 and Figure 7 is the sectional view of Figure 6 (for the sake of clarity, the winding is not shown in Figure 7) Draw), the metal housing 100 is composed of two 3 paper sizes that are applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 470979 B7 7085twf.doc / 008 5. Description of the invention (π) symmetrical Each of the arc pieces has an electrode terminal 106 ′ protruding outward on the upper and lower sides of the arc piece, and has protruding portions 100 a and 100 b protruding inward. This step of inserting the iron core is performed by clamping the upper and lower circular plate parts of the iron core no. 100a and 100b with the protruding portions 100a and 100b of the metal housing 100, respectively, for fixing. Please refer to Figure 4, and then perform a winding process (such as 120 in Figure 1). Wrap the ends and ends of each winding 102 on the electrode terminals 106, as shown in the winding part 108 in Figure 4. Show. The material of the winding 202 is copper wire. Please refer to Fig. 5 'for the wire-wound soldering process (such as 122 in Fig. 丨)' using the solder 104 to fix the wire-wound portion 108 to the electrode terminal 106. Follow-up tests are carried out in sequence (such as the 12th sentence in Figure 1, the seal (such as K6 in Figure 1)) and the packaging process (such as 128 in Figure 1). The conventional choke coil, its electrode terminals and metal The shell is integrally formed, and the core is clamped by the protruding portion of the metal shell. Because the core is a brittle material, the thickness of the upper and lower circular plate surfaces must increase in response to the force generated by the clamp. It is still necessary to maintain the electromagnetic effect of the axial part of the original iron core, and the height of the axial part needs to be maintained unchanged. Therefore, the height of the conventional choke coil is not easy to decrease. The conventional choke coil has a metal case. The weight of the conventional choke coil is not easy to be reduced. After the winding process of the conventional choke coil is completed, it is necessary to carry out the process of inserting the core, and then the winding process is performed, which causes the process to be incoherent. Therefore, the object of the present invention is to provide a surface.

After the winding is completed, the ends and ends of each winding 202 It is wound around the winding notch 203 (as shown in FIG. 15) and the winding part 208 of FIG. 12 respectively on the winding notch 203 of the winding leg 206a of each electrode terminal 206. The material of the 'winding wire 202' includes polyurethane copper wire. In the general winding process, the positions of the winding ends of the wire ends and the wire ends are symmetrical. Take the second winding 202 and the four electrode terminals 206 of the present invention as an example (as shown in FIG. 15). The wire is wound on the wire wound notch 203 of the upper right electrode terminal 206, then this wire is wound 202 9 This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) I \, nnnn I n- ^ aJ 1 nnn I (Please read the notes on the back before filling this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 470979 A7 B7 708 5 twf. Doc / 008 V. Description of the invention (?) The wire wound notch 203 ° of the lower left electrode terminal 206 Please refer to FIG. 13 to perform a wire winding soldering process (such as 222 in FIG. 8), and use the solder 204 to fix the wire wound portion 208 in the wire wound notch. Then carry out subsequent tests (such as 224 in Figure 8), seals (such as 226 in Figure 8), and packaging processes (such as 228 in Figure 8). According to the embodiment, the present invention replaces the conventional metal casing and electrode terminals with surface-adhesive electrode terminals, and does not require the use of a clip to fix the electrode terminals, thereby reducing the thickness of the circular plate surface portion of the core. It can reduce the thickness of the whole choke, and it can also reduce the weight of the whole choke. According to the embodiment, the present invention replaces the conventional metal case and electrode terminal with a surface-adhesive electrode terminal. When it is attached to the electrode terminal, it does not block the winding of the iron core, and can make the coil and the wire wound. Coherent process. The plugging process according to the present invention has at least the following advantages: (1) The conventional metal casing and electrode terminals are replaced with surface-attached electrode terminals, and the electrode terminals are not fixed by using a clip, so that the circle of the core can be reduced. The thickness of the plate surface part can reduce the thickness of the overall choke coil under the same standard of the core electromagnetic effect. (2) Replace the conventional metal case and electrode terminals with surface-adhesive electrode terminals. Under the same standard of core electromagnetic effect, the weight of the overall choke is reduced because the metal case is not required. (3) Surface-adhesive electrode terminals are used to replace the conventional metal case and electrode terminals. When attaching the electrode terminals, the winding of the core will not be blocked, and the winding and winding processes can be made continuous.
