Definitions
- the invention relates to a connection arrangement with an end sleeve which is connected on the inside via a hex connection to a connecting wire of a component and is soldered to a conductor surface of a printed circuit board at a soldering joint.
- the invention further relates to a method for producing an electrical connection between a connecting wire of a component and a printed circuit board mounted on a housing part, in which an end sleeve is connected to the connecting wire by a bead connection and is soldered to a conductor surface of the printed circuit board at a soldering point.
- the invention is based on the object of specifying a connection arrangement of the type specified at the outset and a method for producing it, thus avoiding the problems mentioned above and a reliable production is guaranteed even with an automated procedure.
- the solder joint be arranged in a sleeve section outside the area of the bead connection. This ensures a secure connection of the connecting wire and at the same time an even soldering gap.
- the end sleeve extends through a hole in a printed circuit board and if the soldering point is arranged in a substantially undeformed free end section of the end sleeve which projects beyond the edge of the hole.
- the bead connection is arranged in the region of the hole in the circuit board at a distance from the conductor surface, advantageously in the region of a central section of the end sleeve.
- the bead connection is formed symmetrically by a plurality, preferably four beads distributed in a star shape over the circumference of the end sleeve.
- a further advantageous embodiment of the invention provides that the component and possibly the circuit board are anchored to a housing part via the end sleeve as mechanical connecting means.
- the end sleeve at its connector end plugged onto the connecting wire has a
- the wall opening advantageously has an undercut into which the end sleeve can be latched in a defined manner with a connection end that is flared conically as a front collar, even with diameter tolerances.
- the area of the wall opening following the undercut in the insertion direction of the end sleeve is formed by a stepped bore, the small bore diameter possibly being adapted to the diameter of the end sleeve with tolerance clearance.
- a reliable solder connection is advantageously ensured by the fact that the end sleeve has an undersize in relation to the hole in the printed circuit board while limiting a narrow annular solder gap.
- the connecting wire consist of copper and the end sleeve made of tinned brass.
- the object stated at the outset is achieved in that the end sleeve is anchored in a breakthrough in the housing part by means of a snap connection, and in that the free end section of the end sleeve protruding over the housing part is passed through a hole in the printed circuit board and the solder connection on the outside the area of the bead connection lying solder joint is produced.
- a further improvement of the manufacturing process results from the fact that the bead connection after anchoring the end sleeve in the area of a the breakthrough of the housing part protruding middle section of the end sleeve is made.
- the end sleeve is soldered to the inside of the connecting wire via an end opening of its free end section. It is advantageous here if the soldering point is produced by dip soldering or soldering by means of a soldering wave under the capillary action of a narrow annular soldering gap between the end sleeve and the conductor surface.
- Figure 1 shows an electrical connection arrangement with an end sleeve for connecting a connecting wire of a component with a circuit board mounted on a housing part in a sectional view.
- FIG. 2 shows an enlarged detail of the connection area according to FIG. 1;
- the end sleeve provided with beads or embossments in axial section and in a corresponding side view;
- the arrangement shown in the drawing is used for the mechanical and electrical connection of an electronic component (not shown) to a housing part 10 and a printed circuit board 12 mounted thereon on a broad side.
- the preferred area of application is in the field of automotive engineering, in particular for connecting the interference suppression chokes of brushed motors to control electronics.
- a lead wire 14 of the component is inserted into a hollow cylindrical end sleeve 16 and therein via a crimp or.
- Bead connection 18 set in an electrically conductive connection.
- the end sleeve 16 passes through a wall opening 20 of the housing part 10 and a bore 22 of the printed circuit board 12 aligned therewith and is connected with its free end 24 projecting beyond the edge of the bore 22 on the soldering side 26 of the printed circuit board 10 at a solder joint 28 to a conductor surface 30.
- the bead connection 18 is formed by four oblong-trough-shaped impressions or beads 34, which are distributed in a star shape over the circumference of a central section 32 of the end sleeve 16 and are separated from one another in the circumferential direction by remaining web areas 36.
- Plastic deformation of the connecting wire in the area of the bead base thus results in an inseparable, rigid connection of the connection partners 14, 16.
- the deformed connection area lies within the bore 22 of the printed circuit board 12, while the soldering point 28 is arranged outside of it in the essentially undeformed end section 24 of the end sleeve 16. This measure makes it possible to keep a defined narrow soldering gap 38 between the end sleeve 16 and the conductor surface 30, into which the solder is drawn as an annular soldering grape due to the capillary filling pressure.
- the end sleeve 16 is anchored in a fixed manner in its displacement in the wall opening 20 at its connecting end 40 facing the connecting wire 14 via a snap-in or snap connection 42.
- the wall opening 20 is provided with an undercut 44 which tapers inwards in a funnel shape and with which a conically widened end face collar 46 of the end sleeve 16 can be brought into engagement.
- the area of the wall opening 20 adjoining the undercut 44 is formed by a chamfered stepped bore 48, the small diameter of which is adapted to the end sleeve 16, possibly with a tolerance gap.
- the end sleeve 16 is inserted in a pre-assembly stage by means of a dome as an auxiliary tool into the opening 20 of the housing part 10, which is designed as an injection molded part, and anchored via the snap connection 42.
- the connecting wire 14 is then inserted into the end sleeve 16 and the bead connection 18 is produced by means of a suitable crimping tool. This also ensures that the component is fixed in the correct position.
- the printed circuit board 12 is placed on the protruding central section 32 of the end sleeve 16 and the soldered connection is made at the essentially undeformed solder joint 28 in the region of the free end section 24, preferably by means of a soldering wave in a wave bath.
- an inside solder connection between the end sleeve 16 and the connecting wire 14 is also achieved via the front opening of the free end section 24.
- the end sleeve also ensures a mechanical connection between the housing part 10 and the printed circuit board 12.
