Definitions

  • the present invention relates to the general technical field of the electrical connection and more particularly the connection of parts in relative motion.
  • the present invention relates to any application comprising a movable portion, in motion relative to a fixed part, an electrical connection to be established between the parts.
  • a movable portion in motion relative to a fixed part, an electrical connection to be established between the parts.
  • electrical connection to be established between the parts.
  • These latter consist for example of a connector and a moving contact surface.
  • the present invention relates more particularly to the field automobile, in which it is often necessary to resort to such connectivity, especially in the environment of the columns of direction. It is therefore often necessary to make a connection between a first fixed element and a second movable element, linked to a housing in motion, for example rotating with the steering wheel direction.
  • the interface is connected to the flexible blades by any means and in particular by welding points and must be fixed or must be optimally arranged in relation to moving parts relative and the wires used. This also poses congestion problems often difficult to solve and reliability issues.
  • the object of the present invention is to provide a connecting device between moving parts that do not have the same disadvantages of the state of the art and allowing by its use of reduce the number of parts to establish the electrical connection.
  • Another object of the present invention is to provide a connection device whose technical characteristics make it possible to respond to different constraints and requirements related to making a sliding contact on the one hand and the connection to a standard connector on the other.
  • each electrical branch has two ends of different cross section, the elastic member being realized with the end having the smallest cross section.
  • each electrical branch is made of one piece.
  • each electrical branch is made of two pieces joined together by welding or riveting points.
  • the parts connecting zones components of the electrical branches are covered at least in part by the support, which is made of plastic.
  • the support is an overmolded part.
  • the first electrical interface presents a series of connection terminals made for the ends, protruding out of the support and intended to be engaged in the connector.
  • the elastic members are blades Flexible.
  • connection terminals made for the ends and the flexible blades made for the other ends extend in directions having an inclined angular inclination between 30 ° and 180 °, and preferably close to 90 °.
  • the present invention also relates to a control under a steering wheel vehicle comprising an electrical connection device as presented above.
  • the electrical connection device according to the invention is shown in FIGS. Figures 1 to 3 is intended to be mounted for example on or in the vicinity of a steering column of a vehicle.
  • the electrical connection device makes it possible to electrically connecting a contact surface 1 having conductive tracks 2 to a standard electrical connector not shown.
  • the contact surface 1 is for example in motion relative to the electrical connection device.
  • the movement is in general but not exclusively a rotation.
  • the electrical connection device comprises electrical branches 3 electrically insulated from each other. We can refer for example to Figure 2.
  • certain electric branches 3 are electrically connected to each other.
  • a first electrical connection interface is made with a first end 4 of the electric branches 3, adapted to the mounting of the connector. These first ends 4 are for example intended to engage in the standard electrical connector.
  • a second electrical connection interface is made with the seconds ends 5 of the electric branches 3. These second ends 5 have elastic members making a sliding contact with the contact area 1.
  • the electrical connection device also comprises a support 6 in plastic material providing mechanical support for electrical branches 3 between them. This is how the electrical connection device conforms to the invention has different technical characteristics to each of these electrical connection interfaces.
  • the standard electrical connector not shown is mounted directly on the first ends 4, and without use of an intermediate piece.
  • each electrical branch 3 presents a different cross section at both ends 4 and 5.
  • the organs elastics are made with the ends 5 having the smallest section cross. The latter is chosen to guarantee their flexibility and a contact optimal with the contact surface 1, which is made to move for make sliding contacts.
  • the end 4 of the electric branches advantageously has a larger cross-section to give them rigidity more important mechanics, which allows them to be engaged indirectly in a standard electrical connector.
  • each electrical branch 3 is made in one piece.
  • the latter is for example obtained by molding or by cutting and stamping.
  • the number of component parts of the electrical connection device is therefore very limited and its realization is particularly simple.
  • each electrical branch 3 is made in two pieces interconnected by welding or riveting points. It is so possible to connect together parts with a cross-section more important realizing the first ends 4 to be engaged in the standard electrical connector and cross sectional parts less important properties of elasticity and flexibility to ensure sliding contacts.
  • the binding areas of the parties components of the electrical branches 3 are advantageously covered by the support 6 made of plastic.
  • the support 6 made of plastic material is example a molded part partially covering the electric branches 3 except the ends 4 and 5 of said branches 3.
  • FIG. 2 is a simplified representation partially cut away support 6 made of plastic.
  • the first electrical interface present advantageously a series of connection terminals made by the first ends 4 projecting out of the support 6 and intended to be engaged in the electrical connector.
  • the second ends 5 are preferably flexible blades constituting the elastic members.
  • connection terminals made by the ends 4 and the flexible blades made by the second ends 5 of the electrical branches 3 extend in directions having a angular inclination between 30 and 180 °, and preferably close to 90 °.
  • the second ends 5 components of the flexible blades therefore extend substantially parallel or slightly inclined relative to the plane of extension of the contact surface 1 and the connection terminals made by the first ends 4, extend substantially orthogonally with respect to the contact surface 1, facilitating the engagement of the electrical connector.
  • the angular orientation between the terminals and the flexible blades can be adjusted.
  • the support 6 of plastic is split in a first part 7 and a second part 8.
  • the first and second parts 7 and 8 are, for example, overmolded respectively on the branches 3 electrical components of the first and second electrical interface link.
  • the electrical connection device according to the invention is particularly well suited for its use in steering wheel controls in the environment of the steering columns of vehicles.
  • the support 6 and / or the parts 7, 8 can also constitute one or several electronic circuits. Electronic components can also be positioned between the electrical branches to create specific electrical signals.
  • the device according to the invention has the advantage of reducing the number of intermediate parts needed to establish links electric.
  • Another advantage of the device according to the invention is related to the large number of mechanical configurations and miniaturization that we can consider.
  • the device according to the invention also has a robustness increased electrical connection, even in case of miniaturization.
