    • PROBLEM TO BE SOLVED: To provide a board fixing structure that prevents or reduces play or overstress of a wiring board when holding the wiring board in a base body and a cover body by absorbing dimensional variations thereof.SOLUTION: A wiring board 1 is provided with one circularly sectioned through hole 11 penetrating in a thickness direction in each corner portion in correspondence with projecting portions 21, 31. A tip portion of the projecting portion 21 of a base body 2 is formed in a conical rib 22 as a radially contracted portion continuously radially contracted (tapered) toward the tip (upper end). The conical rib 22 has a continuous radial change in an insertion direction so as to coaxially enter the through hole 11 of the wiring board 1 from the tip side and, in the inserted state (mounted state) in the through hole 11, slantingly touch an insertion side inner circumferential edge (lower inner circumferential edge) of the through hole 11.
    • 要解决的问题:提供一种板固定结构,其通过吸收其尺寸变化来将电路板保持在基体和盖体中时,防止或减少布线板的播放或过度应力。 解决方案:布线板1在突出部21,31对应于每个角部设置有沿厚度方向贯通的一个圆形截面贯通孔11.基体2的突出部21的前端部 形成为径向收缩部分的圆锥形肋22朝向尖端(上端)连续径向收缩(锥形)。 锥形肋22在插入方向上具有连续的径向变化,从而从末端侧同轴地进入布线板1的通孔11,并且在插入状态(安装状态)中,在通孔11中倾斜地触摸 通孔11的插入侧内周缘(下内周缘)。版权所有(C)2012,JPO&INPIT
