Definitions

  • the invention relates to an electrical contact between a component and a flexible cable set.
  • a connector of this type includes contact devices arranged on a side surface of the connector housing.
  • the connector housing receives the contact connections of an inserted flexible cable and brings them into electrical contact with the contact devices.
  • the connector also includes a slider to press the contact terminals of the flat flexible cable against the contact devices in the connector housing and to contact the contact devices. After the cable has been inserted into the housing, the slider is fitted into the connector housing in order to clamp the inserted cable section with the connector housing.
  • the invention is based on the object of specifying an electrical contact between a component and a flexible wiring harness which is particularly simple to implement.
  • a contact area of the wiring harness arranged in a predetermined bending area of the flexible wiring harness is in electrical contact with a mating contact area of the component, the predetermined bending area being maintained by means of a fixing element.
  • the predetermined bending area of the line set preferably has at least one preformed fold running transverse to the line direction.
  • the present contacting can thus be used in a variety of ways and is not restricted to flat contact areas or counter-contact areas.
  • the fixing element has a mechanical holding function in order to make the position of the cable set relative in the contact position to maintain the component.
  • the fixing element preferably also has an electrical function. With this function, the fixing element can close one or more circuits of the component together with corresponding electrical contact areas of the line set and counter-contact areas of the component.
  • the fixing element is preferably designed as a component of the component.
  • the fixing element also has only a mechanical fixing function as part of the component.
  • the fixing element is designed as a clamping part, which generates a clamping force that maintains the electrical contact between the contact area and the counter-contact area in the contact pitch.
  • the clamping part ensures the stability of the electrical contact between the component and the wiring harness through clamping forces, in particular pressure forces.
  • the clamping part is for electrical contacts in confined spaces, e.g. B. in installation spaces of motor vehicles, particularly suitable, since no more space for electrical plugs or sockets must be kept.
  • the clamping part has a U-shaped cross section with U legs as the clamping leg generating the clamping force.
  • the clamping legs can be designed to be resilient in the effective direction of the clamping force. A flat electrical contact between the contact area in the predetermined bending area of the wiring harness and the mating contact area of the component is thereby supported.
  • the spring elasticity contributes to the contact pressure being adaptable in the sense of reliable electrical contacting depending on the geometrical dimensioning of the contact area and / or counter-contact area.
  • the component is preferably designed as a circuit board, as a cable set, in particular as a flexible flat cable set, or as a control device. This is the possibility given to combine a flexible cable set with a fixed and / or with a flexible component.
  • Figure 1 is a side view of a flexible wiring harness and a component before electrical contact in a schematic representation.
  • FIG. 2 shows a side view of the flexible cable set and the component according to FIG. 1 after the electrical contact has been made in a schematic representation
  • Fig. 3 shows the introduction of a mating contact area of a component in a flexible cable set in a perspective view.
  • the flexible cable set 2 shown in FIG. 1 is electrically contacted with a component 4 in the form of a printed circuit board.
  • the cable set 2 is designed as a flexible flat cable set and has three folds 8 transversely to the line direction 30 in a predetermined bending area 6.
  • the folds 8 are selected such that the contact area 10 in the predetermined bending area 6 of the wiring harness 2 completely covers a mating contact area 12 of the component 4 after the contact has been made, in other words that there is effective electrical contact between the contact area 10 of the wiring harness 2 and the mating contact area 12 of component 4 is guaranteed.
  • the predetermined bending area 6 can individually adapt to the geometry of the component 4.
  • a fixing element 14 is designed as a clamping part, which in the contact position is the electrical contact generating clamping force between contact area 10 and mating contact area 12 (FIG. 2).
  • the number of folds can vary depending on the geometric configuration of the component.
  • the contact area 10 in the predetermined bending area 6 of the cable set 2 is flush with the mating contact area 12 of the component 4, the predetermined bending area 6 being maintained by the fixing element 14.
  • the fixing element 14 With its U-legs 16, the fixing element 14 generates a clamping force in the effective direction 32, so that good electrical contact is ensured. Vibration or other external forces caused by driving in a motor vehicle can thus be absorbed without the strength of the electrical contact being impaired.
  • the fixing element 14 designed as a clamping part has a U-shaped cross-section with the U-legs as the clamping leg 16 generating the clamping force, for flush adaptation to the mating contact area 12 of component 4, the clamping leg 16 are designed to be resilient in the effective direction 32 of the clamping force.
  • the contact pressure is automatically adjusted.
  • the wiring harness 2 therefore lies essentially flush on the component 4 on three sides.
  • component 4 can have a different shape, the configuration of fixing element 14 being adapted correspondingly to the geometry of component 4 for effective electrical contacting.
  • the component can be designed, for example, as a circuit board, as a cable set, in particular as a flexible flat cable set, or as a control device.
  • FIG. 3 shows the introduction, indicated by an arrow 20, of the component 4 designed as a circuit board into the line set 2 in a perspective illustration.
  • the mating contact area 12 of the component 4 is a component of four conductor tracks 22, which correspond to a corresponding number of a further four conductor tracks 24 in the wiring harness 2, in order to ensure complete electrical contact between the wiring harness 2 and the component 4.
  • Component 4 has electronic structures (not shown) for performing various functions. For example, data transmission and / or control functions for actuators or sensors can be carried out as operational functions via the electrical contact.
  • the component may not include any electronic structures.
  • the component has one or more electrical contacts as an electrical or electronic component.
  • control units, actuators, sensors etc. are thus achieved by means of a film / flat conductor technology without the use of complex contact systems. Due to the simple implementation and the small space requirement, the present electrical contacting proves to be advantageous, inter alia, when expanding or retrofitting special equipment for existing flat conductor electrical systems in motor vehicles.

Abstract

Pour établir un contact électrique entre un composant (4) et un faisceau de câbles souple (2), une zone de contact (10) située dans une zone flexionnelle théorique (6) dudit faisceau de câbles souple (2) est disposée dans une position de contact électrique de façon à se trouver en contact électrique avec une zone de contact correspondante (12) dudit composant (4), ladite zone flexionnelle théorique (6) étant maintenue en position verticale à l'aide d'un élément de fixation (14). Ainsi, l'invention permet de réduire les moyens techniques mis en oeuvre pour établir un contact électrique.
