Definitions

the invention relates to a method for producing connecting lugs on hybrid housings according to the preamble of claim 1.
hybrid housings are commercially available components which are used, for example, in communications technology or in data processing.
connection lugs From EP 0 270 820 B1 an IC component with connecting lugs is known, in which a closed lead frame with inwardly directed connecting lugs is first punched out of sheet metal during the production of the connecting lugs. The free ends of the connection lugs are then connected, for example by means of bonding, to corresponding connection surfaces of the integrated circuit and then hermetically sealed by encapsulation with plastic.
the plastic capsule forms a housing from which the connecting lugs still connected to the lead frame protrude on four sides.
four lead combs are created formed, the connecting lugs are bent together with the webs of the conductor combs and the webs are then separated from the connecting lugs.
the free ends of the connection lugs are all in one connection plane and allow surface mounting of the component in this embodiment.
DE 35 44 125 C2 discloses a surface-mountable connector in which, for example, three rows of contact elements are arranged one above the other in an insulating body.
the connecting lugs led out at the rear of the insulating body of different lengths each have step-shaped bends such that the lower lug legs of each row of contacts lie side by side in a connection plane.
the flag legs of the second row of contacts are aligned behind those of the first row of contacts and the flag legs of the third row of contacts are behind those of the second row of contacts.
the invention has for its object to provide a method for producing terminal lugs on hybrid housings, with which the number of terminal lugs lying parallel in a row in a connecting plane can be substantially increased by commercially available, approximately 5.30 mm high housing troughs.
the object is achieved with the features specified in claim 1.
a further solution to the object on which the invention is based is specified in claim 5.
the solutions have the advantage that, with the same dimensions of the hybrid housing, the number of connecting lugs led out on each side of the housing trough can be almost doubled. Further procedural features can be found in the subclaims.
the housing trough of a commercially available hybrid housing made of Kovar is designated by 1.
the housing trough 1 has a base area of 60 mm ⁇ 60 mm and a trough height of approximately 5.30 mm.
connecting lugs are glazed into a row of holes.
two rows of bores 2, 3 are first made in each side wall of the housing trough 1 with a parallel spacing and a gap.
two versions of conductor combs 4, 5 are punched out of sheet metal, one version of which has longer connecting lugs 7 hanging on a web 6 than the connecting lugs 9 connected to the web 8 of the other embodiment.
the glass leadthroughs produced in this way are briefly called glazings 11 below.
connection lugs 7, 9 After the connection lugs 7, 9 have been glazed in, the housing trough 1 is fed to a molding tool (not shown) for further processing and is fed into centered this.
the molding tool consists of two halves of the tool, which have depressions corresponding to the grid of the connecting lugs. These recesses are offset between the upper and the lower half of the tool, whereby the connecting lugs 7, 9 are clamped directly onto the glazing 11 when the tool halves are closed.
the connecting lugs 7, 9 are then bent by lowering a die, in which they are fixed in position.
the connecting lugs 7 of the conductor comb 4 glazed into the first row of holes 2 are bent between the connecting lugs 9 of the other, remaining flat conductor comb 5 such that the webs 6, 8 do not touch.
the web 6, the connecting lugs 7 of which are bent by cranking protrudes from the sheet metal plane of the non-deformed conductor comb, in particular from the web 8 thereof, at an acute angle.
a cutting tool is attached to the forming die, with which the webs 6, 8 of all conductor combs 4, 5 are separated from them in the same operation after the connecting lugs 7, 9 have been bent.
the dividing line 14 is at a short distance from the webs (FIG. 2).
connecting lugs 7, 9 are shown, which can be produced with modified tools, in particular the form stamp.
the terminal lugs 7, 9 are mutually in a common, before separating the conductor comb webs the two rows of glazing 11 lying connection level bent, while in Fig. 4 terminal lugs 7, 9 are shown, the two rows of which have been bent towards the same side in a common connection level. This can take place both towards the edge of the housing trough 1 and towards the trough bottom 10.
connection lugs 7, 9 lying in a connection plane can be arranged.
connection lugs made of sheet metal, which have a halving pitch.
the conductor comb has a number of connecting lugs corresponding to the number of the two rows of bores 2, 3. Up to 90 pieces therefore hang on the bridge of the conductor comb.
the two rows of bores 2, 3 on each side of the tub are then fitted with the flag ends 12, 13 of a conductor comb and then glazed. The web is then separated from the connecting lugs by punching away.
