Definitions

  • the present invention relates to a connector system.
  • the present invention relates to a plug connection system which is typically used at an electrical voltage of 60 volts or more, in particular in connection with batteries for vehicles with electric drive with an electrical power of the drive train of at least 12 kW.
  • Batteries, which are used to drive vehicles electrically are so-called high-voltage batteries, which typically have an output DC voltage of 60 V and higher, in particular up to 2 kV, depending on the drive concept selected and the minimum motor and maximum generator voltages that occur.
  • a high-voltage battery requires a switching device, generally called a switch box or S-box, to switch the energy flow on and off.
  • a switching device generally called a switch box or S-box
  • This can be located as an integrated switch box inside the battery housing or as a switch box that is separately arranged outside the battery. If a separate switch box is used, the inputs of the switch box must be electromechanically connected to the battery outputs in such a way that no live part is exposed. In the case of separate switch boxes, the connection to the battery must also be made directly, i.e. without an intermediate set of cables. This means that all cable set plug connections are ruled out as a solution.
  • this connection is made using RADSOK® connectors, for example the RADSOK® D14.
  • RADSOK® connectors are expensive and allow only a tolerance compensation in the range of a few tenths of a millimeter both with regard to the two contacts of the RADSOK® connector and with regard to the contact of the connection pieces, eg the connection pieces on the battery and switch box.
  • This has the disadvantage that the pin and socket position of the contacts of the socket part-side connection pieces as well as the plug part-side connection pieces have to be tolerated very closely and thus cost-intensive.
  • these connectors allow relative movements between the pin and socket in the mating direction even in the mated state, which can lead to increased wear and premature failure of the connector.
  • the object of the invention is therefore to use means that are as simple as possible to provide a plug connection system which enables a higher manufacturing tolerance with regard to the connection pieces and is designed to be wear-resistant.
  • a plug connection system comprises a plug part and a socket part electrically connected to the plug part, the plug part comprising at least one contact element with an end facing away from the socket part and an end facing the socket part, the end facing away from being designed to establish an electrical connection with a not from Plug connection system comprised plug part-side connector in a plug-in direction, the socket part having at least one busbar, the at least one busbar having a first, essentially non-elastic section and a second, elastic section, the second elastic section being designed in such a way that with this a transverse force transverse to the plug-in direction, in particular in the longitudinal direction of the at least one busbar, can be absorbed by elastic deformation, and the at least one busbar with a non-plug connection system includes Most socket part-side connector is connectable.
  • Such a plug connection system can advantageously be used as a plug connector between a high-voltage battery and a switch box assigned to the high-voltage battery for controlling the flow of energy.
  • the connector system does not include a harness, i. is free of a cable set arranged between the plug part and the socket part and is particularly suitable for use in electric drives of all types of vehicles.
  • An elastic deformation is considered to be a deformation which is not plastic, i.e. enables reversible energy absorption and release through mechanical deformation.
  • the busbar In an installed state of the plug-in connection system, the busbar has an initial state that is left when a force is applied depending on the direction of the force, but is resumed after the force has been applied, or in a state deflected from the initial state, restoring forces occur which restore the state of the busbar approximate the initial state.
  • At least one power rail conceptually includes one, two, three or four power rails.
  • Each busbar itself can be formed from a plurality of electrically conductive elements connected to one another, such as a laminated busbar.
  • Such a plug connection system can provide significantly greater compensation options for relative movements of the connection pieces and the plug connection system.
  • the tolerances of the connection pieces can be manufactured with less accuracy, which means that their manufacture is significantly cheaper in terms of costs.
  • the relative movement of the contacts between the socket part and the plug part is significantly reduced or minimized.
  • the socket part has at least one receiving socket for receiving and making electrical contact with the at least one contact element, the at least one receiving socket being connected in an electrically conductive manner to the at least one busbar, and the elastic section of the at least one busbar being designed such that the absorption of forces like that takes place that when the transverse force, ie a force with transverse components to the plug-in direction, acts on the at least one busbar, the at least one receiving socket and the at least one contact element are fixed and / or positionally fixed to one another.
  • Fixed in this context means fixed in the position, while fixed should indicate that the alignment of the respective components should be unchanged relative to one another.
  • a transverse force is considered to be a force which has an active component in a plane perpendicular to the insertion direction.
  • the second, elastic section of the at least one busbar is designed as a meander.
  • the meander forms an elastic section of the at least one busbar due to its design and its properties.
  • a meander is to be understood as a loop-like, convex or concave shape of the busbar. In particular, this can be realized, for example, by an essentially semi-cylindrical jacket surface which forms the first elastic section of the busbar.
  • a single meander can be provided; however, several meanders can also be provided along the busbar, which meanders, for example, are alternately concave and convex in the longitudinal direction of the busbar.
  • the convex and / or concave design allows the busbar to develop an elastic behavior, depending on the design of the meander or meanders, for example its radius, rigidity, etc.
  • the at least one busbar is a laminated copper busbar, which is compacted outside the elastic section.
  • the compacted area forms the first, non-elastic section of the busbar.
  • the first elastic section, which is not compacted, can be formed in this embodiment by a correspondingly suitable meander.
  • the elastic section of the at least one busbar is designed such that an elastic compression or expansion of the at least one busbar of at least 1 millimeter to 5 millimeters relative to the at least one connection socket can be carried out or realized.
  • a reference point is used here, for example, which is arranged on the busbar in the longitudinal direction on that side of the elastic section which faces away from the connection socket.
  • the socket part comprises a first busbar and a second busbar, the first and second busbars each having a first, essentially non-elastic section and a second, elastic section, the two busbars being arranged such that the respective elastic sections are each arranged on the socket part side, on different sides of the socket part, in particular opposite sides of the socket part.
  • the elastic sections of the first and second busbars are arranged and aligned on opposite sides of the socket part in such a way that their longitudinal axes or current conduction directions have an angle of approximately 180 ° or are aligned antiparallel.
  • the plug part can be positioned with an additional centering device relative to the socket part, so that the socket part is stationary relative to the plug part in the plugging direction and / or transversely to the plugging direction.
  • the centering device By means of the centering device, the socket part and the plug part and, if necessary, further components of the plug connection system can be aligned with one another in the desired manner.
  • the centering device is designed as a separate part, for example a housing part, which determines the position and / or orientation of the Socket part to the plug part, in particular the at least one contact element to the at least one connection socket. This avoids a misalignment of the socket part to the plug part or their components, which further reduces the wear and tear on the components of the plug-in system and the electrical connection pieces.
  • the centering device has a first non-electrically conductive housing part which is attached to the at least one busbar, the first non-electrically conductive housing part having a recess into which the receiving socket protrudes and the at least one is fixed in the receiving socket Contact element protrudes in the plugging direction, the first non-electrically conductive housing part having at least one centering means with which the at least one contact element can be positioned or centered relative to the first non-electrically conductive housing part.
  • the centering means relative fixation of the desired arrangement and alignment of busbar, receiving socket and contact elements relative to one another takes place.
  • the first non-electrically conductive housing can advantageously be plugged onto the busbar, the attachment preferably having locking means so that the housing cannot be displaced along the busbar.

  • the force absorbing device preferably also has elastic properties so that the forces in the plug-in direction can be absorbed in this way.
  • the force absorbing device can be used repeatedly or permanently in order to absorb or compensate for forces in the insertion direction.
  • This is preferably formed from a non-electrically conductive material in order to avoid inadvertent contact with the at least one contact element, for example plastic.
  • the force absorbing device can be designed as a separate part or as part of the first non-electrically conductive housing part and has at least one function of absorbing forces in the plug-in direction and, if necessary, of compensating for them by elastic deformation.
  • the force absorbing device can be part of the centering device or be comprised by it.
  • the force absorption device is designed as a plastic attachment with a spring function in the plug-in direction. This dampens a force in the direction of insertion. The mechanical load in the plugging direction on the contact element and the receiving socket is reduced by the suspension. This further reduces the wear and tear on the connector system.
  • An inexpensive, non-electrically conductive force absorbing device is thus provided.
  • the force absorption device has at least one recess through which the at least one contact element protrudes.
  • the force absorbing device can be designed in such a way that the at least one recess supports the centering of the plug part and the socket part with respect to one another.
