Definitions

  • the invention relates to a method for welding a plastic housing according to the preamble of claim 1.
  • a circuit carrier such as a circuit board is arranged inside the housing, which in turn must be attached to a housing half, especially if acceleration sensitive sensors are arranged on this circuit substrate, which a correspondingly rigid attachment for receiving the sensed Need accelerations.
  • an oil filter in eime plastic housing is also known, in which the elsesiche filter medium is bent by a clamping rib in a formation, a part of the filter medium, the clamping rib engages behind and is secured substantially form-fitting manner, wherein the plastic housing
  • the object of the present invention is to provide a method for welding a plastic housing, in which particularly inexpensive and yet secure the circuit board can be attached.
  • the circuit board is inserted.
  • An essential idea of the invention is that on the other housing part a molding is provided towards the circuit board and the housing part is pressed with the molding during welding in the direction of the circuit board, preferably until a predetermined counterforce is achieved, and also during cooling a predetermined force is exerted on the housing part with the shaping, so that a frictional attachment of the circuit board in the housing is achieved.
  • the pressing ensures a fixation of the printed circuit board in the predetermined position and prevents floating of the circuit board and the spread of melt in critical regions of the circuit board.
  • the pressing causes a spring-like tension of the housing part with the shape.
  • the preferred laser welding is always discussed below in the embodiments, however, the invention is also suitable for other forms of local welding, such as friction welding, ultrasonic welding, etc.
  • the invention is a new concept for closing a plastic housing with a lid, with simultaneous attachment of a circuit board, during a welding operation, for example via a laser.
  • the goal is the PCB so too
  • the circuit board is fixed by stops on the lid frictionally in the housing.
  • the joining path is, by the stops, depending on the board thickness. He is for example at 0.4-0.8mm.
  • the fixation of the PCB is always done with different thickness tolerances of the PCB with the same force and over the life of a secure fixed fixation is generated, for example suitable for vibration-free mounting of the PCB without additional components (eg screws, gluing) and transmission of crash pulses.
  • a watertight housing closure takes place.
  • the advantage of this concept is that it is necessary to attach the circuit board and closing the housing only one operation. Furthermore, the mounting surface of the circuit board is much larger than the conventional hot gas riveting. However, the space requirement on the circuit board is lower because the contact surfaces affect only the edge zone of the circuit board.
  • This edge zone in turn is defined as a barrier zone due to the separation of the individual circuit board from the benefit. Due to the larger contact surface preload losses caused by creep of the plastic are not disturbing in appearance.
  • this method is very reliable, since the sweat path is controlled by means of a force evaluation. Therefore, the welding process can be stopped when the biasing force increases (after the stops on the printed circuit board have come to rest) without overstressing the printed circuit board.
  • the welding of a lid is much more material-saving than the casting of the circuit board.
  • a welding process also saves considerable time because the welded joint cools faster and does not have to dry.
  • the electrical contacting of the circuit board can be done both in a conventional manner, with Pressfitein expertsn, as well as with single pins or direct connections.

Abstract

Selon le procédé, la carte de circuit imprimé (3) est introduite dans une partie de boîtier (2). Une protubérance (1.1) s'étendant en direction de la carte de circuit imprimé (3) est formée sur l'autre partie de boîtier (1) et une pression est appliquée, pendant le soudage, sur la partie de boîtier (1) présentant la protubérance (1.1), de préférence jusqu'à ce qu'une force antagoniste prédéfinie soit atteinte. De plus, une force prédéfinie est exercée, même lors du refroidissement, sur la partie de boîtier (1) présentant la protubérance (1.1) et la carte de circuit imprimé (3) est ainsi immobilisée à force dans le boîtier. Pendant le soudage, l'application d'une pression permet d'immobiliser la carte de circuit imprimé (3) dans la position prédéfinie et empêche que la carte de circuit imprimé (3) ne flotte et que le métal fondu ne se répande dans des régions critiques de la carte de circuit imprimé. En outre, l'application de pression provoque une précontrainte élastique de la partie de boîtier (1) présentant la protubérance (1.1). Grâce au maintien d'une force prédéfinie pendant le refroidissement, la carte de circuit imprimé (3) reste immobilisée dans le boîtier par l'intermédiaire de la protubérance (1.1) et la contrainte ne peut pas se relâcher, mais est plutôt encore renforcée par le retrait du matériau lors de son durcissement. Il est ainsi garanti que, même après le durcissement, la protubérance (1.1) appuie sur la carte de circuit imprimé (3) avec une force prédéfinie et immobilise ainsi à force ladite carte de circuit imprimé dans le boîtier d'une manière extrêmement fiable.
