Description
一種電感，尤其是指一種低電感值高功率電感。An inductor, especially a low inductance, high power inductor.
目前市場上的低電感值高功率電感一般分為二種，一種為插針式，使用本體導線做引腳實現產品功率最大化，但存在以下缺點，使用時必須進行人工插件，耗費大量人工，無法進行自動化製程；另一種為貼片式（Surface Mounted Devices，SMD）功率電感，先前製程一樣，增加料片，焊接後成型為SMD功率電感，使用時能實現表面貼裝技術(Surface Mount Technology， SMT）自動貼片，但存在以下缺點，產品本體與引腳有焊接點，從而可能產生開路及接觸面不夠，無法有效發揮最大功率，且因焊接料片而須將本體引出導體裁切，形成浪費。At present, low-inductance and high-power inductors on the market are generally divided into two types, one is a pin type, and the body wire is used as a pin to maximize product power, but the following disadvantages exist, and a manual plug-in must be used when using, which requires a lot of labor. It is impossible to automate the process; the other is a Surface Mounted Devices (SMD) power inductor. As in the previous process, the chip is added, and the SMD power inductor is formed after soldering. Surface mount technology can be realized when used. SMT) automatic patch, but the following shortcomings, the product body and the pin have solder joints, which may result in open circuit and insufficient contact surface, can not effectively maximize the power, and the body lead conductor must be cut due to the welding of the material, forming waste.
因而，在中華人民共和國公開第CN 204537823 U號的新型專利中公開了一種低電感值高功率電感，其透過本體導線引出磁殼外直接成形為導線引腳，進而形成類SMD功率電感的產品，具有使用方便、性能好、成本低等優點。然而，其本體導線需透過扁平化製程來成形為導線引腳，而扁平化製程使本體導線形變產生扁平貼片面，不僅有損導體本體結構，而且導線形變容易引起部分斷裂，甚至產生開路，降低產品可靠性，從而影響性能。另外，其形變後側面變得不規則而需切邊整形，因而產生材料上的浪廢，同時產生扁平化、切邊、人工上錫等工序，增加大量工時費用。Thus, a novel low-inductance, high-power inductor is disclosed in the new patent of the National Publication No. CN 204537823 U, which is directly formed into a wire lead through a body lead and is formed into a SMD-like power inductor. It has the advantages of convenient use, good performance and low cost. However, the body wire needs to be formed into a wire lead through a flattening process, and the flattening process deforms the body wire to produce a flat patch surface, which not only damages the conductor body structure, but also causes the wire deformation to cause partial breakage or even an open circuit. Reduce product reliability and thus performance. In addition, after the deformation, the side surface becomes irregular and needs to be trimmed, thereby causing waste on the material, and at the same time, processes such as flattening, trimming, and manual tinning are generated, which increases the labor cost.
本創作的目的在於提供了一種低電感值高功率電感，無需扁平化製程，可有效節約加工成本、提高產品性能。The purpose of this creation is to provide a low-inductance, high-power inductor that eliminates the need for a flattening process and saves processing costs and improves product performance.

作為上述低電感值高功率電感的改進，所述磁殼為一端開口的罩體結構，所述磁殼的開口端的對應兩側分別設有一引腳導線槽，以分別引出所述導線引腳。As a modification of the low-inductance and high-power inductor, the magnetic shell is a cover structure with an open end, and corresponding sides of the open end of the magnetic shell are respectively provided with a lead wire slot to respectively lead out the lead pins.
