Assembly method for mounting a printed circuit board in a housing and associated assembly tool

摘要

An assembly method for a printed circuit board (3) is specified which enables the printed circuit board (3) to be positioned particularly precisely in a housing (2). In the assembly method, the printed circuit board (3) provided with catch holes (40) is placed on catch pins (22) of an (assembly) tool (1) corresponding to the catch holes (40), such that the catch pins (22) on a side facing away from the tool ( 41) protrude beyond the printed circuit board (3). The tool (1) is then moved against a circuit board receptacle (51) of the housing (2) such that the catch pins (22) engage in a form-fitting manner in corresponding centering holes (31) in the circuit board receptacle (51). After the subsequent fixing of the printed circuit board (3) in the housing (2), the tool (1) is pulled back out of the catch holes (40) while detaching the catch pins (22), the printed circuit board (3) remaining in the printed circuit board receptacle (51). The tool (1) comprises in particular an upper plate (5), to which the catch pins (22) are assigned, and a lower plate (4), which has a housing receptacle (10) for positioning the housing (2). The circuit board (3) can be placed on the catch pins (22) with the catch holes (40) provided therein. Furthermore, the printed circuit board (22) can be inserted into the printed circuit board receptacle (51) of the housing (2) by moving the upper plate (5) against the lower plate (4).
