Definitions
- the invention relates to a housing for an electrical circuit consisting of a first housing part, in or on which the circuit and at least one electrical Connection point for the circuit is arranged, and a second housing part in which at least one connecting conductor is arranged, the circuit inside the housing by contacting the connection point with an electrical line outside the Housing connects.
- the two housing parts are used to form the housing together.
- ballast for gas discharge lamps in one Motor vehicle.
- a ballast consists of a base plate as the first Housing part on which the electrical circuit with the connection points is arranged, and a housing cover as a second housing part, in which the connection conductors sit.
- the object of the invention is to provide a generic housing for an electrical circuit create where the connection points on the circuit in easier and more reliable Way with the connection conductors for the electrical outside the housing Lines can be contacted.
- connection conductors in Joining direction of the two housing parts are resilient, the Connection conductor in the assembled state of the two housing parts under compression be pressed against the connection point.
- the spring-elastic design of the connecting conductors in the joining direction makes it easier and reliably causes tolerance compensation in the joining direction of the housing parts. This is particularly important if the installation position of the circuit (incl. Connection points) in the first housing part due to manufacturing tolerances in the joining direction (z direction) has a certain inaccuracy.
- the resilient Connection conductors designed so that they are always within the tolerance range cause reliable contacting, the tolerance compensation by a different elastic compression of the connecting conductor is effected.
- the pressure forces change only slightly; Pressure forces that destroy the circuit carrier could be avoided. This is particularly advantageous if a Circuit carrier made of ceramic is used, which is naturally very brittle and therefore is sensitive to breakage.
- the type of spring according to the invention has Contacting still the advantage that this contacting is detachable. This is special In the case of a repair, this is an advantage if, for example, a defective circuit is replaced shall be.
- Figure 1 shows a section through the two housing parts (I, II) before assembly.
- the Joining direction in which the two housing parts are assembled corresponds to drawn z-axis.
- the first housing part (I) is shown in the Embodiment designed as a metallic base plate on which a circuit carrier (4), for example made of ceramic, is fastened by means of an adhesive (6).
- the actual circuit is not shown.
- a connection point (1) for is located on the circuit carrier (4) the electrical circuit.
- This connection point (1) is a metallic contact plate formed and fixed via a solder connection (7) on the circuit carrier (4). That the Contact plates forming connection point (1) can, for example, be made of a base material exist like copper and have a precious metal coating, e.g. B. made of gold.
- connection conductor (2) In the second housing part (II), which is mounted on the base plate (I) as the upper housing part is a spring-elastic connecting conductor in the joining direction of the two housing parts (I, II) (2) arranged the circuit inside the housing by contacting the Connection point (1) with an electrical line (not shown) outside the housing combines.
- connection conductor (2) In the assembled state of the two housing parts, the connection conductor (2) pressed against the connection point (1).
- the connection conductor (2) is configured at its connection point (1) End (2A) half S-shaped. With a larger housing, the connection conductor (2) also be S-shaped.
- the manufacture of an S-shaped spring is special simple and inexpensive to implement by using the connection conductor (2) as a stamped and is formed in accordance with an S-shaped sheet metal strip, preferably with a Gold plating is provided.
- connection conductor (2) has in the embodiment shown a dome-shaped elevation (2A *).
- This Elevation (punch) is advantageously produced by embossing the metal strip.
- the connecting conductor (2) With this mark (2A *) the connecting conductor (2) becomes almost punctiform or at least with a small surface pressed against the connection point (1), which is sufficient large contact force for the electrical contacting is ensured.
- much larger area of the Connection point (2) forming contact plate is thereby ensured that the Surface pressure applied to the circuit carrier (4) is low.
- This is in particular in the case of a circuit carrier (4) made of a brittle material, such as ceramic, from Advantage.
- the dome-shaped design of the contact plate (1) is in any case a sufficient normal force of the resilient connection conductor (2) on the contact plate causes - even if the connection conductor (1) opposite the contact plate (1) is slightly inclined due to tolerances.
- a centering of the connecting conductor (2) in one piece is advantageously trained mark (2A *) in the plane perpendicular to the joining direction (x, y plane).
- tolerance compensation perpendicular to the joining direction.
- the connecting conductor (2) has one at its end (2B) lying outside the housing Connector pin (2A) for connecting a connector connected to the electrical cable (not shown).
- the connecting conductor (2) itself is held in a plastic part (3), that was sprayed around the connecting conductor (2) as an insert.
- This plastic part (3) is arranged with the connecting conductor (2) in an opening of the second housing part (II).
- the opening also forms the plug-in area (5) for receiving the electrical plug Line off.
- the second housing part (II) consists of Metal, the plastic part (3) with the connection conductor (2) being embedded directly in the housing part (II) is injected.
- the connecting conductor (2) is over the plastic part (3) thus kept electrically insulated in the metallic upper housing part (II).
- the upper housing part consists of plastic and is manufactured in an injection molding process with the connection conductor embedded.
- the two housing parts are held together, for example, by a screw connection or a clamp.
- the electrical contacting of the connection conductor with the connection point is also automatically effected.
- Both structural tolerances of the two housing parts and tolerances during the assembly (joining) of the two housing parts in all three spatial directions are compensated for, so that reliable contacting of the connection conductor with the connection point is permanently guaranteed.
- this tolerance compensation is brought about by the spring-elastic design of the connecting conductor in the joining direction and by the dome-shaped depression of the connection point in connection with the punched connecting conductor. In this way, relaxation and different setting behavior of different materials (eg the adhesive with which the circuit carrier is fixed), which play a major role, especially in the case of large temperature differences, are reliably compensated for.
- the invention is not based on a housing with a connecting conductor limited to a junction. Rather, are also in the illustrated embodiment perpendicular to the plane of the drawing, several connecting conductors of the same design and Connection points arranged spaced one behind the other.
