Abstract: A main body of an electronic part has multiple electrodes, to which multiple terminals are respectively connected. The terminals include a normal terminal and a fuse terminal, each of which extends from lands formed in a printed board so as to hold the main body at a position above and separated from a board surface of the printed board. The fuse terminal has multiple leg portions divided by slits. A first leg portion forms an electrical path portion having a cut-off portion, a width of which is smaller than that of other portions of the electrical path portion. A second leg portion has a first supporting leg and a second supporting leg, which are arranged at both sides of the first leg portion. Each of the supporting legs is connected to each of dummy lands formed in the printed board.

Abstract: A printed board includes an insulated base, a wiring pattern, and an inspection interrupting portion. The wiring pattern is disposed on a first surface of the insulated base, and includes a wiring portion, a land, and an interrupting portion disposed between the wiring portion and the land. The inspection interrupting portion is made of a same material with the interrupting portion and has a same pattern with the interrupting portion. In order to assure an interrupting performance of the interrupting portion, the inspection interrupting portion is inspected instead of the interrupting portion by applying an inspection current to the inspection interrupting portion.

Abstract: A main body of an electronic part is formed in a rectangular pillared shape having a first and a second axial end surface. A first electrode is formed on the first axial end surface electrically and mechanically connected to a first wiring pattern formed on a board surface of a printed board. A second electrode is formed on the second axial end surface, to which one end of a fuse terminal is electrically connected. The other end of the fuse terminal is connected to a second wiring pattern of the printed board or a wiring member which is formed as an independent member from the printed board. A cut-off portion is formed in a connecting portion of the fuse terminal.

Abstract: A main body of an electronic part has multiple electrodes, to which multiple terminals are respectively connected. The terminals include a fuse terminal and a normal terminal, each of which extends from the main body to a printed board so that the main body is supported at a position above and separated from a board surface of the printed board. The fuse terminal has an intermediate portion between an electrode-connected portion and a land-connected portion. The intermediate portion has a cut-off portion having a smaller width than other portions of the fuse terminal, so that the cut-off portion is melted down when excess current flows in the fuse terminal. The intermediate portion extends in a direction parallel to the board surface or in a direction inclined to the board surface at an angle smaller than 90 degrees.

Abstract translation: 电子部件的主体具有分别连接有多个端子的多个电极。 端子包括保险丝端子和正常端子，每个端子从主体延伸到印刷电路板，使得主体被支撑在印刷电路板的板表面上方和离开印刷电路板的位置。 熔丝端子在电极连接部分和平台连接部分之间具有中间部分。 中间部分具有比熔丝端子的其它部分更小的宽度的截止部分，使得当过剩的电流在熔丝端子中流动时，截止部分被熔化。 中间部分在平行于板表面的方向上或者以小于90度的角度沿与板表面倾斜的方向延伸。
