Definitions

  • the invention relates to an electrical device, in particular a switching or control device for motor vehicles, according to the preamble of the main claim.
  • electrical devices are known in a large variety of embodiments. Particularly when used in automotive electrics, these are exposed to different environmental influences, such as: B. moisture, penetrating salt, vibrations, etc. against which they should be resistant. At the same time, the space requirement of such devices must be as small as possible, since often only a limited installation space is available. In addition, a construction that is as simple and inexpensive as possible is sought.
  • the electrical device has to accommodate a sometimes very extensive and complex electronic circuit which, above all, also meets the requirements with regard to the mechanical loads (vibration resistance) that arise from use in a motor vehicle (for example when installed in the engine compartment) ⁇ kick.
  • the electrical device with the characterizing features of the main claim has the advantage that there is a particularly space-saving design, since the printed circuit board, which carries an electronic circuit, is flexible and is arranged in a rolled-up form in a housing.
  • the resulting curvature of the printed circuit board gives it a relatively high stability, despite the flexible design.
  • the electrical device according to the invention is characterized by a simple, compact structure, but can nevertheless have complex, complex circuits which are accommodated, for example, on a printed circuit board which has a very large footprint.
  • the dimensions of the printed circuit board, in particular the longitudinal extent, can be a multiple of the length of the housing.
  • FIG. 1 shows in FIG. 1 a cross section through an electrical device in a simplified representation and in FIG. 2 shows a section along II-II according to FIG. 1.
  • the electrical device shown in FIGS. 1 and 2 essentially has a housing 10, a printed circuit board 11 which carries an electronic circuit, and a plug connector 12.
  • the housing 10 consists of a housing base body 14, a side wall 15 and an end wall 16.
  • the housing base body 14 is composed of a base part 17, a side wall 18 and a rear wall 19 and a cover 20, and is a uniform, coherent component Made of plastic.
  • the transition 21 between the rear wall 19 and the cover 20 is rounded, the radius corresponds approximately to half the distance between the cover 20 and the base part 17.
  • the base part 17 is elongated, so that a fastening section 22 is formed which has a bore 23, which is used to fasten the housing at the installation site.
  • the side wall 15 also made of plastic as an individual part is connected to the housing base body 14, for. B. glued or ultrasonically welded, that it is opposite its side wall 18 approximately parallel.
  • Both side walls 15, 18 are provided on their opposite surfaces each with a spiral groove 25, 26, each starting from a wedge-shaped groove 27, 28, of which only the groove 27 formed in the side wall 18 is shown.
  • These wedge-shaped grooves 27, 28 are formed on the inner surface of the side walls, specifically in their upper region, on the side facing away from the rear wall 19.
  • the open side of the housing is closed by the end wall 16. This has an opening 29 into which the plug connector 12 is inserted.
  • the end wall is provided on the inside with locking tongues 30 which cooperate with correspondingly designed locking lugs 31 in the basic housing body.
  • the basic housing body 14 and the side wall 15 are connected to the end wall 16 firmly but releasably.
  • the end wall 16 has in the region of the base part 17 an approximately parallel to this, outwardly facing fastening section 33, which is provided with holes 34.
  • the flexible printed circuit board is rolled up approximately in a spiral and is guided in the corresponding spiral grooves 25, 26 of the side walls.
  • a section 37 of the printed circuit board extends to the end wall 16 and is fastened to the inside thereof, for. B. glued.
  • the circuit board is connected to the connector strip 12, which is known per se, and which carries a multiplicity of connectors 38 which are arranged next to one another and in two rows one below the other.
  • the contact pins 39 of the plug penetrate the printed circuit board and are soldered to it.
  • Power components 40 are attached to the printed circuit board between the contact pins and the base part and are likewise connected to the latter.
  • thermal energy can be dissipated from these power components to the end wall, which is preferably made of metal for this purpose.
  • this can additionally be provided on the outside with cooling fins.
  • the cooling surface can thereby be made relatively large.
  • the assembly of the printed circuit board or its layout is selected such that all components which heat up strongly are arranged on the section 37 fastened to the end wall 16.
  • the free end of the printed circuit board 11 with the opposite edge regions is inserted into the wedge-shaped grooves 27, 28 of the side walls.
  • the printed circuit board By further pushing in, the printed circuit board, the width of which is somewhat greater than the distance between the side walls, reaches the area of the spiral grooves 25, 26 and is guided through them and rolled up when pushed in.
  • the end wall 16 lies with the section 37 of the circuit board attached to it open side of the housing so that locking lugs 31 and locking tongues 30 lie opposite one another. By pressing in the end wall or the locking tongues, it locks with the locking lugs, so that the housing is closed.
  • these snap-in connections enable the housing to be opened easily, so that the printed circuit board can be pulled out of the housing again for maintenance or for subsequent adjustment.
  • a circumferential groove can be made into which a corresponding sealing ring is inserted. It is also possible to glue the end wall tightly to the basic housing body, but this makes subsequent opening of the housing more difficult.
  • the spiral grooves are formed so that the circuit board is inserted and fixed without opposite areas of the circuit board touching.
  • the width of the grooves is expediently greater than the thickness of the circuit board. This also prevents excessive stress on the discrete components or their connection to the printed circuit board and the printed circuit board itself when it is inserted.
  • the discrete components are preferably arranged in rows which run approximately parallel to the end wall (from side wall to side wall). In addition, they are expediently oriented so that their longitudinal extension also extends in this direction. Furthermore, it is advantageous to carry out the assembly or the layout of the circuit board such that wide discrete components are arranged relatively close to section 37 of the circuit board, i. H. in areas of the printed circuit board with little curvature.
  • the vibrating strength very high ie the mechanical strength is much greater than with flat or folded flexible printed circuit boards, so that the risk of a short circuit due to unintentional contact between adjacent printed circuit board sections is very low.
  • the housing 10 shielding i. that is, to improve the electromagnetic compatibility (EMC) of the circuit
  • its plastic parts can be coated on the inside or the outside with a metallic or an electrically and / or magnetically well-conductive coating.
