Description

PCB board spacer

Technical Field

The utility model relates to the technical field of spacer columns, in particular to a PCB board spacer column.

Background Art

In electronic products and electrical equipment, in order to separate one circuit board (PCB board) from another circuit board (or housing) to prevent short circuit and damage of components on the circuit boards, generally, multiple spacer columns are set between the two circuit boards (or the circuit board and the housing) to separate the two.

A spacer column as shown in FIG1 is one of the commonly used spacer columns for circuit boards, and includes a spacer portion 10 and two elastic hooks 20 arranged at both ends of the spacer portion 10, and each elastic hook 20 also has a corresponding elastic abutment plate 30. When in use, the two elastic hooks are inserted into the through holes of the two circuit boards, and the elastic abutment plates corresponding to each elastic hook abut against the corresponding circuit boards respectively, so as to achieve the separation of the two circuit boards. The above-mentioned spacer column usually requires sufficient installation space on the circuit board (the positions corresponding to the elastic hooks and the elastic abutment plates on the circuit board should avoid setting components to prevent the components from being damaged by the spacer column), and the spacer column can only play a spacing role for the circuit board, and cannot connect the circuit board and the casing. When the circuit board needs to be fixed to the casing, additional fasteners are required.
