Printed circuit board with counter bores

带沉孔的印刷电路板

Abstract

The utility model belongs to a printed circuit board with counter bores, which mainly consists of a printed circuit board and component holes. The inverted cone counter bores which are sunken downwards are arranged on the printed circuit board at intervals. In the utility model, fixing holes on the printed circuit board are the inverted cone counter bores which are sunken downwards. The utility model has the advantages of not occupying limited space of the upper end of the printed circuit board, making electric components arranged at the upper end of the printed circuit board tightly connected with the board surface of the printed circuit board, being favorable for fixing the electric components and being favorable for fixing the printed circuit board with a corresponding electric appliance shell.
本实用新型属于一种带沉孔的印刷电路板,主要由印刷电路板和元件孔所组成,印刷电路板上间隔距离设有呈倒圆台形向下凹陷的沉孔。本实用新型使印刷电路板上的固定孔为倒圆台形向下凹陷的沉孔,有不占用印刷电路板上端的有限空间,使印刷电路板上端设置的电器元件与印刷电路板板面紧密连接,利于电器元件的固定,利于印刷电路板与对应电器壳体的固定的优点。
