  • the invention relates to a connector for electrical components in motor vehicles with a punching comb, which forms terminal contacts for a counterpart of the connector, a cable with insulated electrical connection lines, which are electrically connected to the punching comb, a first connector housing part made of hard plastic, to which the cable is attached and through which the punching comb protrudes and a second plug housing part made of a soft plastic, which immediately surrounds the individual lugs of the punching comb along an extension portion of the lugs.
  • Such connectors are used in motor vehicles for the electrical connection of various electrical units, such as actuators for throttle valves or other valves and flaps, which are electrically adjusted, electric pumps or electrically operated position sensors.
  • the connectors are on the one hand to be produced as inexpensively as possible, on the other hand, they must meet high demands in terms of their tightness and thermal resistance.
  • the best possible tightness is especially desired along the connecting lines or the punching comb in the interior of the plug, since otherwise moisture could get in the direction of the electronic components, which leads to short circuits and errors in the electronics.
  • a plug connector is proposed in DE 100 41 812 A1, in which initially a soft plastic surrounds a section of a punching comb for sealing.
  • This soft plastic is in turn encapsulated by a harder plastic, which is at the same time formed so that the wall element is formed by the hard plastic, so it replicates the actual plug shape.
  • the outer hard plastic presses on the inner soft plastic, whereby the sealing effect is to be improved.
  • this connector should also be inexpensive to produce, have a small footprint, prevent kinking of the connection cable as possible and ensure a firm connection to the counterpart.
  • the soft plastic is a thermoplastic elastomer or a silicone elastomer. Both materials have good sprayability and very good sealing effects.
  • the second plug housing part surrounds the first plug housing part in a region in which the tabs project out of the plug connector and in a region in which the cable protrudes from the plug connector. This protects the hard plastic from damage in the area of the electrical cables. It is particularly advantageous if the second plug housing part extends beyond the first plug housing part along the cable. Thus, the effect of a grommet around the cable, whereby a kinking of the cable, which can lead to breakage of the connecting lines, is prevented.

  • the second housing part can be clamped in a simple manner with its stop surface against the counterpart, whereby the axial seal is ensured.

It is important in particular that both the cable 2 in the area in which it protrudes from the connector and the punching comb 14 in the region 38 in which the flags protrude from the housing of the connector, are surrounded by plastic plastic directly. Also, the intermediate area is surrounded by soft plastic to provide the opposite soft plastic areas an effective grip on hard plastic.

  • the region 36 extends beyond the first housing part along the cable 2 and thus acts in this area as a spout 40, through which a kinking of the cable is avoided.
  • the region 38 protruding beyond the plates 26 in the insertion direction and adjoining the plate-shaped section 22 has an elongated shape, so that all six lugs 12 of the punching comb 14 are surrounded over a defined length of soft plastic.
  • the vertical surface forms the contact surface 48 for a male connector and is disposed between the two plates 26.
  • This contact surface 48 which extends perpendicularly to the plug-in direction, has an elastic design, so that a sealing deformation of this region occurs when it is connected to the plug counterpart. This prevents moisture from entering between the two connector parts.
  • the deformation takes place in particular by screwing the first Plug housing part 18 via the through holes 28 on the connector counterpart, whereby bearing surface 48 acts as an axial seal.
  • the elongate region 38 serves as a seal between the individual lugs 12.
  • a cost-producible connector is provided, which is insensitive to moisture, since both in the axial direction in the connector connection via the elastic contact surface 48 and along the punching comb 14 is reliably sealed. Nevertheless, the connector has sufficient stability. Damage to the electrical connection is also avoided by the position of the cable and its connection.

Abstract

L'invention concerne des connecteurs connus pour des composants électriques dans des véhicules automobiles, comprenant : un peigne d'estampage (14) formant des contacts de connexion (16) pour une pièce complémentaire du connecteur ; un câble (2) doté de conduites de connexion électriques (6) isolées connectées électriquement au peigne d'estampage (14) ; une première partie de boîtier de connecteur (18) en matière plastique dure contre laquelle le câble (2) est fixé et à travers laquelle le peigne d'estampage (14) fait saillie ; une deuxième partie de boîtier de connecteur (32) en matière plastique souple entourant directement les languettes de connexion (12) individuelles du peigne d'estampage (14) le long d'une partie d'étendue des languettes (12). Mais lesdits connecteurs ne proposent fréquemment pas de protection contre la pénétration d'humidité dans la zone des contacts de connexion (16). A cet effet, la deuxième partie de boîtier de connecteur (32) fait saillie de la première partie de boîtier de connecteur (18) dans la direction d'enfichage du connecteur, la partie (38) de la deuxième partie de boîtier de connecteur (32), faisant saillie de la première partie de connecteur, comportant une surface d'appui (48) pour une pièce complémentaire du connecteur.
