Definitions

  • the present invention relates to the general technical field of electrical connection and more particularly the connection of parts in relative motion.
  • the present invention relates to any application comprising a moving part, moving relative to a fixed part, an electrical connection to be established between said parts.
  • the latter consist for example of a connector and a moving contact surface.
  • the present invention relates more particularly to the automotive field, in which it is often necessary to use such a connection, especially in the environment of the steering columns. It is therefore often necessary to make an electrical connection between a first fixed element and a second movable element, linked to a moving housing, for example rotating with the steering wheel (see document US-A-6,007,344).
  • the interface is connected to the flexible blades by any means and in particular by welding points and must be fixed or must be arranged optimally relative to the parts in relative motion and son used. This also causes congestion problems often difficult to solve and reliability problems.
  • the object of the present invention is to provide a device for electrical connection between parts in relative movement does not have the disadvantages of the state of the art and allowing its use to reduce the number of parts to establish the electrical connection.
  • Another object of the present invention is to provide an electrical connection device whose technical characteristics make it possible to meet various constraints and requirements related to the realization of a sliding contact on the one hand and to the connection to a standard connector. somewhere else.
  • each electrical branch has two ends of different cross section, the elastic member being made with the end having the smallest cross section.
  • each electrical branch is made in one piece.
  • each electrical branch is made in two parts interconnected by welding or riveting points.
  • connection zones of the constituent parts 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 has a series of connection terminals made for the ends, protruding from the support and intended to be engaged in the connector.
  • the elastic members are flexible blades.
  • connection terminals made for the ends and the flexible blades made for the other ends extend in directions having an angular inclination of between 30 ° and 180 °, and preferably close to 90 °.
  • the present invention also relates to a steering wheel control of a vehicle comprising an electrical connection device as presented above.
  • the electrical connection device according to the invention is shown in 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 is used to electrically connect 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 usually but not exclusively a rotation.
  • the electrical connection device comprises electrical branches 3 electrically insulated relative to each other. We can refer for example to Figure 2.
  • certain electrical branches 3 are electrically connected to each other.
  • a first electrical connection interface is made with a first end 4 of the electrical 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 second ends 5 of the electric branches 3. These second ends 5 comprise elastic members establishing a sliding contact with the contact surface 1.
  • the electrical connection device also comprises a support 6 made of plastic material that mechanically holds the electrical branches 3 together.
  • a support 6 made of plastic material that mechanically holds the electrical branches 3 together.
  • the standard electrical connector not shown is mounted directly on the first ends 4, and without the use of an intermediate piece.
  • each electrical branch 3 has a different cross section at its two ends 4 and 5.
  • the resilient members are made with the ends 5 having the smallest cross section. The latter is chosen to guarantee their flexibility and an optimal contact with the contact surface 1, which is caused to move to make sliding contacts.
  • the end 4 of the electrical branches advantageously has a larger cross section so as to give them a greater mechanical rigidity, 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 very limited and its implementation is particularly simple.
  • each electrical branch 3 is made in two parts interconnected by welding or riveting points. It is thus possible to connect together parts having a larger cross section providing the first ends 4 intended to be engaged in the standard electrical connector and smaller cross-sectional portions having elasticity and flexibility properties allowing ensure sliding contacts.
  • the connection zones of the constituent parts of the electric branches 3 are advantageously covered by the support 6 made of plastic.
  • the support 6 made of plastic material is for example a molded part partially covering the electrical branches 3 except the ends 4 and 5 of said branches 3.
  • Figure 2 shows in a simplified manner partially cut the support 6 of plastic.
  • the first electrical interface advantageously has a series of connection terminals made by the first ends 4 protruding from 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 formed by the ends 4 and the flexible strips produced by the second ends 5 of the electric branches 3 extend in directions having an angular inclination of between 30 and 180 °, and preferably close to one another. 90 °.
  • the second constituent ends 5 of the flexible strips therefore extend substantially parallel or slightly inclined with respect 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 material is split into a first portion 7 and a second portion 8.
  • the first and second parts 7 and 8 are for example overmoulded respectively on the electrical branches 3 constituting the first and the second electrical connection interface.
  • the electrical connection device according to the invention is particularly well suited for use in steering controls in the environment of the steering columns of vehicles.
  • the support 6 and / or the parts 7, 8 may further constitute one or more 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 necessary for the establishment of electrical connections.
  • Another advantage of the device according to the invention is related to the large number of mechanical configurations and miniaturization that can be envisaged.
  • the device according to the invention also has increased robustness of the electrical connection, even in the case of miniaturization.
