Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
131 words
A device for mounting electric components on a printed circuit board having openings adapted to receive locking members therethrough, comprising a housing, said housing including a first and second section, a preselected plurality of legs depending from said first section and sized and positioned to extend through the respective openings in the circuit board, said legs including first locking means engageable with the board for locking said first section in position on the board; said second section having receiving means for receiving an electric component therein, second complimentary formed locking means on said first and second section engageable with each other for maintaining said second section in one of two positions with respect to said first section, wherein said second section is closer to the circuit board in the second position.
Claim 2
Independent Claim
131 words
A device for mounting electric components on a printed circuit board having openings adapted to receive locking members therethrough, comprising a housing, said housing including a first and second section, a preselected plurality of legs depending from said first section and sized and positioned to extend through the respective openings in the circuit board, said legs including first locking means engageable with the board for locking said first section in position on the board; said second section having receiving means for receiving an electric component therein, second complimentary formed locking means on said first and second section engageable with each other for maintaining said second section in one of two positions with respect to said first section, wherein said second section is closer to the circuit board in the second position.
Claim 3
Dependent Claim
47 words
A device as in claim 1, in which said second locking means includes a plurality of webs adapted to extend into the circuit board openings when said second section is in said second position to maintain each one of said plurality of legs in the associated opening.
Claim 4
Dependent Claim
87 words
A device as in claim 1, in which the circuit board is provided with passages adapted to receive connector wires therethrough, and wherein said second section is provided with depending connector wires adapted to be connected to the leads of the electric component in said receiving means, and respective aligned guide means in said first and second sections for receiving said connector wires therethrough, said guide means being located to overlie a respective passage in said board when said first section is locked on the circuit board.
Claim 5
Dependent Claim
98 words
A device as in claim 1, in which said second locking means includes a plurality of webs depending from said second section and in one-to-one correspondence with said plurality of legs, and engaging means on each of said plurality of legs for engaging a respective one of said webs to retain said first and second sections in a desired one of said two positions, each of said webs being located in juxtaposition to a respective one of said legs, whereby said webs are moved into the circuit board openings to maintain each of said plurality of legs therein.
Claim 6
Dependent Claim
40 words
A device as in claim 4, in which said second locking means comprises a projection on each of said plurality of legs, and at least one spaced recesses on each of said webs adapted to receive the corresponding projection therein.
Claim 7
Dependent Claim
