按，隨著科技時代的不斷進步，許多電子、電氣產品被研發問世，提供人們更舒適的日常生活中，而各種電子、電氣產品例如手提音響、收錄音機、影音放映機(如VCD、DVD或藍光DVD等)、電腦或筆記型電腦等都要用電，必須透過電源連接器與市電插座或充電器等電性插接，以供電子、電氣產品獲得所需電源而能運作。 According to the continuous advancement of the scientific and technological era, many electronic and electrical products have been researched and developed to provide people with a more comfortable daily life. Various electronic and electrical products such as portable audio, radio cassette recorders, and video projectors (such as VCD, DVD, or Blu-ray) DVDs, etc.), computers or notebook computers, etc. all require electricity, and must be plugged into the mains socket or charger via a power connector, so that the power supply and electrical products can obtain the required power to operate.
而電源插座內部不可或缺的元件是至少一根金屬插銷，傳統的金屬插銷可分為空心與實心兩種，如第十四圖所示，空心金屬端子係在一金屬板材，例如銅板沖出一預定造形之片體，然後將其一端捲曲為圓柱形之接觸部A，另端則延伸一扁平狀之端子部B，該接觸部A與端子部B係為一體成型製成，而非鉚接連接，該空心金屬端子之缺失則在於，因係透過捲曲成型，在捲製的過程中力量的掌控相當重要，若施力過大或施 力不足，則二側邊無法在接合位置緊密的相對接合，並容易導致板材翹曲或變形，以致產品不良率提高，且空心金屬端子的結構強度差，與相對型式電連接器插接時，容易造成金屬端子受力則發生變形、扭曲或斷裂等現象，此外，片狀捲曲之插銷前緣包合處會形成接縫，而嚴重影響產品外觀。 The indispensable component inside the power socket is at least one metal pin. Traditional metal pins can be divided into hollow and solid. As shown in Figure 14, the hollow metal terminal is tied to a metal plate, such as a copper plate. A predetermined shape of the sheet body, and then one end is rolled into a cylindrical contact portion A, and the other end is extended to a flat terminal portion B. The contact portion A and the terminal portion B are integrally formed instead of riveting. The connection, the lack of the hollow metal terminal is that because the coil is formed by curling, the control of power during the rolling process is very important. If the force is insufficient, the two sides cannot be tightly and relatively joined at the joint position, and it is easy to cause warpage or deformation of the plate, so that the product defect rate is increased, and the structural strength of the hollow metal terminal is poor. When it is plugged into the opposite type electrical connector, It is easy to cause the metal terminal to deform, twist or break when it is stressed. In addition, the front edge of the pin-shaped curling pin will form a seam, which will seriously affect the appearance of the product.
