发明名称 ELECTRONIC PART AND ELECTRONIC CONTROL UNIT
摘要 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.

主权项 1. An electronic part mounted to a printed board comprising: a main body arranged at a position above and separated from a board surface of the printed board, the main body having at least one electronic element and multiple electrodes for the electronic element; and multiple terminals, each of which is connected at its one end to each of the electrodes and electrically and mechanically connected at its other end to a land formed in the printed board, each of the terminals extending from the main body toward the printed board so as to hold the main body at the position above and separated from the board surface in a condition that each of the terminals is electrically and mechanically connected to the respective electrodes and the respective lands; wherein each of the terminals has an electrode-connected portion electrically and mechanically connected to the corresponding electrode, a land-connected portion electrically and mechanically connected to the corresponding land, and an intermediate portion for connecting the electrode-connected portion and the land-connected portion with each other, wherein the terminals include at least one fuse terminal, wherein the fuse terminal has a first connecting portion at least as a part of the intermediate portion, the first connecting portion extending in a direction parallel to the board surface or in a direction inclined with respect to the board surface by an angle smaller than 90 degrees, wherein the fuse terminal further has a cut-off portion formed in the first connecting portion, wherein the cut-off portion, which has a width smaller than that of other portions of the fuse terminal, is melted down due to heat generation by excess current, and wherein the fuse terminal has tapered portions at both sides of the cut-off portion, so that the cut-off portion is respectively connected to the electrode-connected portion and the land-connected portion via the respective tapered portions.
