ABSTRACT:
In connection with a method and a device for mounting electric components, such as coils, anti-interference coils, transformers, transistors, capacitors, or the like, on a circuit board, it is proposed to give the carrier housing for the electric component a two-part design and to lock the lower part directly on the printed circuit board, while an upper housing part serving as a component carrier may be locked in two different positions on the lower housing part. In the first, extended locking position of the two housing parts detent legs provided on the lower housing part can be brought into locking engagement with passages in the printed circuit board, if necessary by an additional rotary movement, while in the compressed position locking webs projecting from the upper housing part engage and fix the said detent legs from the rear or laterally, and electric connection wires projecting from the electric component may, if desired, be guided by means of wire-guiding sleeves provided on the housing through, corresponding passage openings in the printed circuit board, simultaneously with and due to the compression of the housing parts.
