Definitions

  • the invention relates to a cover for a chamber of a housing of a device, with an approximately plate-like carrier which carries a printed conductor pattern designed as a lead frame, with a sensor arranged on the printed conductor pattern and a plug receptacle formed on the carrier for a device plug for contacting the printed conductor pattern ,
  • the object of the invention is therefore to provide a lid of the type mentioned, which consists of simple components, is easy to assemble and ensures proper functioning.
  • the lead frame is held on the approximately plate-like support, held by fixing elements and covered by a cover connected to the support at its peripheral edge.
  • the separately produced lead frame is applied to the carrier, which is also produced separately, and is held in its installed position by the fixing elements. The connection points are then separated and the cover is applied.
  • Plug contacts so that only small distances between the conductor tracks of the conductor pattern are necessary. This also allows the size of the cover to be kept small.
  • the sensor can easily be applied before the lead frame is installed. This makes it possible to manufacture the lead frame with the sensor at a different location than the location where the carrier and cover are produced, so that production can be carried out more efficiently, flexibly and cost-effectively.
  • the lead frame can have contact tongues for contacting the device connector, which protrude into the connector receptacle.
  • the contact tongues can be component-reducing, in particular parts of the lead frame bent out of the plane of the lead frame.
  • the connector receptacle can be sleeve-like
  • Carrier be formed protruding, wherein the connector receptacle is preferably formed in one piece with the connector.
  • the carrier plate can have one or more bushings through which one or more further contact tongues on the side of the carrier plate facing away from the lead frame are excellently guided.
  • the one or more further contact tongues in particular parts of the leadframe which are bent out of the plane of the leadframe, are also.
  • the carrier can have a sensor housing on its side facing away from the lead frame, into which the sensor protrudes, the carrier and sensor housing preferably being formed in one piece.
  • the further contact tongues and / or the sensor or the sensor housing can protrude into the chamber of the housing.
  • the cover is welded to the carrier at its peripheral edge, in particular laser-welded, or glued in a component-saving manner.
  • the cover prefferably connected to the support with its peripheral edge by means of a peripheral seal on the support and, in particular, by a screw connection.
  • the fixing elements are latching elements or clamping elements into which the lead frame can be snapped or clamped.
  • the carrier can be a plastic part, in particular a plastic injection-molded part, that is easy to manufacture and at the same time isolates the conductor tracks from one another.
  • the cover is a shell-shaped or cup-shaped plastic part, in particular a plastic injection-molded part.
  • the lead frame can be constructed in different ways.
  • the leadframe can be punched out of a metal sheet (leat frame) or from a printed circuit board carrying conductor tracks.
  • the carrier can be connected to the housing by means of screws, closing the chamber of the housing.
  • the lid can be used for a wide variety of devices. So he can e.g. can be used on accelerator pedal modules.
  • a preferred use is that the device is a throttle valve assembly for an internal combustion engine, in particular of a motor vehicle, and a continuous throttle opening is formed in the housing, which can be shut off by a throttle valve arranged on a throttle valve shaft, an electromotive drive being arranged in the housing which is pivotally drivable, in particular via a gearbox.
  • the sensor can be a position sensor that detects the position of the throttle valve shaft or the transmission.
  • the at least one or further contact tongues can be a motor connector for contacting the electromotive drive.
  • FIG. 1 is a perspective view of a throttle body
  • Figure 2 is a basic exploded view of a
  • FIG. 3 shows a perspective view of a lead frame
  • the throttle valve connector 1 shown in the figures has a housing 2 in which a throttle opening 3 is formed.
  • a throttle valve shaft 4 is guided transversely through the throttle opening 3 and carries a throttle valve 5, through which the passage cross section of the throttle opening 3 can be blocked.
  • the housing cover 8 has a plate-like carrier 9, which is an insulating plastic injection molded part, a sleeve-like connector receptacle 10 for contacting a device connector, a pot-like sensor housing 11 and a further connector receptacle 12 of a motor connector, all of which protrude into the pot-like housing chamber.
  • a lead frame 6 is placed on the side of the carrier 9 facing away from the housing chamber, and the conductor tracks 7 of the lead frame 6 are held in position by latching elements (not shown). After this latching fastening of the conductor tracks 7 on the carrier 9, the connection points 13 of the conductor tracks 7 of the lead frame 6 are separated.
  • End regions of the conductor tracks 7 are bent at right angles from the plane of the lead frame 6 and form contact tongues 14 which protrude through corresponding bushings in the carrier 9 into the plug receptacle 10.
  • Another bent contact tongue 15 also protrudes through the carrier 9 and protrudes into the connector receptacle 12, which forms a motor connector for contacting the electric motor.
  • the conductor tracks 7 of the leadframe 6 are completely covered by a shell-like cover 17, which is laser-welded to the carrier 9 on its peripheral edge and thus the space of the conductor tracks 7 is sealed off.
  • the carrier 9 and thus the entire housing cover 8 is connected to the housing 2 by means of screws 18 and closes the housing chamber from the outside.

Abstract

L'invention concerne un couvercle destiné à une chambre d'un carter (2) d'un appareil. Ce couvercle comporte un support de type plaquette (9) supportant un réseau de conducteurs sous la forme d'une grille estampée (6), réseau de conducteurs sur lequel un capteur (16) est installé. Ledit support (9) est également pourvu d'un logement à connecteur (10) destiné à loger un connecteur d'appareil permettant la mise en contact du réseau de conducteurs. Ladite grille estampée (6) est maintenue en appui sur ce support de type plaquette (9) par des éléments de fixation et recouverte par une pièce de recouvrement (17), reliée au support (9) au niveau de son bord périphérique.
