Definitions

  • the invention relates to a connection system for an electric bicycle with a plug, with a plug receptacle and with a locking device to lock the plug relative to the plug receptacle.
  • Bicycles can have supporting electric motors in order to relieve the cyclist, e.g. on inclines or when accelerating.
  • the motors of such electric bicycles can be located at the bottom bracket and have sensors that detect the torque at the bottom bracket and the speed of the bicycle. From a comparison of the measurement data, a control unit determines whether the motor has to accelerate the electric bicycle in order to relieve the driver or to maintain a predetermined speed.
  • the motors need electrical lines to the energy storage devices and the peripheral devices in order to transmit energy or signals. Since the peripheral devices are usually not attached to the engine itself but at another point on the frame of the bicycle, cables are used for the connection, which are connected to the corresponding connections via electrical connectors.
  • the electrical plug connections must be protected from the influence of moisture. In addition, it must be taken into account that there is often not much installation space available for electrical plug connections in electric bicycles.
  • the invention is based on the object of presenting a connection system that is suitable for connection to an electric bicycle and has a compact design. Based on the prior art mentioned, the task is solved with the features of the independent claims. Advantageous embodiments are specified in the dependent claims.
  • the locking device comprises a locking tongue connected to the plug.
  • the connector receptacle has a connector wall surrounding the connector, the connector wall having a sealing section and a locking section, the sealing section and the locking section being arranged one behind the other in the axial direction.
  • the sealing portion of the plug wall forms a sealing transition with the plug.
  • the locking section of the connector wall is interrupted by a recess. In the locked state, the locking tongue is arranged in the recess.
  • the connector and the connector receptacle can be made slim, so that little space is required in the radial direction.
  • the same radial portion in which the seal is formed in the sealing portion is used again in the locking portion to lock the plug to the receptacle. This creates the possibility of arranging a plurality of plugs and plug receptacles next to one another in a small space.
  • the seal located between the plug and the wall of the plug can extend without interruption around the perimeter of the plug.
  • the seal can be permanently connected to the plug or to the plug socket, for example by the sealing material being applied by two-component injection molding.
  • the sealing surface formed on the other part can extend without interruption around the circumference of the connector.
  • the plug includes the seal, while the sealing surface interacting with the seal is formed on the plug receptacle. With such a seal, water can be prevented from penetrating to the plug contacts of the connection system.
  • the direction in which the connector is moved relative to the connector receptacle when the connection system is disconnected and connected is referred to as the axial direction.
  • the direction in which the plug is brought up to the plug receptacle when the connection is established is referred to as the plug-in direction.
  • the sealing section can be arranged in front of the locking section.
  • the recess can form an opening in the connector wall, so that the connector wall has a gap in the area of the recess.
  • the plug wall can be freely continuous in the area of the recess.
  • a web which bridges the recess can be arranged in a radial section adjacent to the plug wall. The web can be part of the locking device.
  • the locking tongue can be adapted to the cross section of the recess, so that the locking tongue fills the recess in the locked state.
  • the plug wall can span a contour in the sealing section, which continues in the locking section.
  • the contour of the plug wall in the locking section can be identical to the contour in the sealing section, with the exception of the recess with which the plug wall is interrupted in the locking section.
  • the locking tongue can continue the contour of the plug wall corresponding to the contour in the sealing section.
  • the sealing tongue can form a continuation of the contour of the plug wall in the sealing section.
  • the connector wall can be parallel to the axis of the plug extend so that the plug wall in the sealing section has the same distance from the axis of the plug as in the locking section.
  • a root of the locking tongue may be connected to the body of the plug.
  • the locking tongue can extend in the axial direction to a free end.
  • the locking tongue can have a locking projection which, in the locked state, interacts with a locking counterpart of the plug receptacle.
  • the latching projection can be provided with an insertion bevel so that the locking tongue is tensioned by the latching counterpart when the plug is inserted into the plug socket.
  • the latching projection can project outwardly from the locking tongue.
  • the locking device may form a rigid lock in which the lock must be released before the connector can be removed from the receptacle. This is to be distinguished from detents, which are overcome by simply applying increased force, see for example EP 2 978 077 A1 .
  • the connector may also have a sealing portion and a locking portion.
  • the sealing section can be arranged in front of the locking section in the insertion direction.
  • the outer circumference of the plug can fit the plug wall of the plug receptacle over the entire circumference.
  • the circumference of the plug can be set back relative to the sealing section, so that a free space remains between the body of the plug and the locking tongue, in particular between the body of the plug and a free end of the locking tongue. It is into this clearance that the latch tongue can move when tensioned relative to the receptacle to release the latch.
  • the rest of the outside areas of the plug can also be adapted to the plug wall in the locking section.
  • the locking device can include a mating latching piece connected to the plug receptacle.
  • the mating latch may include a ridge extending across the recess.
  • the locking counterpart can be arranged radially outside the contour spanned by the plug wall. In the locked state, the locking projection of the locking tongue can be in engagement with a surface of the locking counterpart that is at the front in the direction of insertion.
  • the plug can have exactly one locking tongue.
  • the connector receptacle can have exactly one locking counterpart. This saves space in the radial direction compared to a design in which a plurality of locking devices distributed over the circumference of the plug protrude outwards relative to the plug wall.
  • the locking device can be designed in such a way that the locking tongue is stretched elastically in relation to the locking counterpart for unlocking.
  • the locking tongue can be provided with an actuating projection which projects in the same direction in relation to the locking tongue as the latching projection.
  • the actuating projection can be arranged behind the locking counterpart, viewed in the direction of insertion, and enclose an axial spacing with the locking counterpart.
  • the invention is based on the idea of enabling the plug to be released from the plug socket without tools, by applying finger force between the actuating projection and the counterpart in order to position the locking tongue relative to the latching counterpart to strain.
  • the finger Due to the axial distance between the actuating projection and the counterpart, the finger can be supported on both parts and apply the force required to tighten the locking tongue with a lever movement. As soon as the locking tongue is under sufficient tension relative to the locking counterpart, the plug can be pulled off the plug receptacle in the axial direction.
  • the axial distance between the rear closing surface of the locking counterpart and the actuating projection of the locking tongue can be between 0.1 mm and 5 mm, preferably between 0.2 mm and 2 mm.
  • connection system can include a connection part that has a plurality of plug receptacles.
  • the connecting part can have between two and twelve, preferably between three and eight, plug receptacles.
  • a connection system with such a connection part has independent inventive content, even without the connector receptacle being equipped with a sealing section and a locking section.
  • the connection part can comprise a first plug receptacle and a second plug receptacle which are adjacent to one another such that a plug wall of the first plug receptacle also forms a plug wall for the second plug receptacle (intermediate plug wall).
  • the intermediate plug wall may be free of an element of a locking device. In this way, a particularly space-saving arrangement of the connector receptacles is possible.
  • the first connector receptacle and the second connector receptacle can each have a latching counterpart, so that the intermediate connector wall is arranged between the latching counterpart of the first connector receptacle and the latching counterpart of the second connector receptacle
  • the connector receptacle can include a latching counterpart, the latching counterpart being arranged in a section of the connector wall opposite the intermediate connector wall.
  • the connector receptacle can include a plurality of plug contacts. The plug contacts can be arranged along a straight line.
  • the connector may include a third connector receptacle separated from the first connector receptacle by an intermediate connector wall.
  • the plug contacts of the first plug receptacle can be arranged along a straight line with the plug contacts of the third plug receptacle.
  • the first connector receptacle and the third connector receptacle can each include a counterpart latching piece, with the counterpart latching pieces also being arranged along a straight line.
  • the connection part can include a fifth connector receptacle, so that the plug contacts of the first, third and fifth connector receptacle are arranged along a straight line.
  • the connector may include a fourth connector receptacle separated from the second connector receptacle by an intermediate connector wall.
  • the plug contacts of the fourth plug receptacle can be arranged along a straight line with the plug contacts of the second plug receptacle.
  • the fourth connector receptacle may be separated from the second connector receptacle by an intermediate connector wall.
  • the connector may include a sixth receptacle having an intermediate receptacle wall with the first receptacle and the second receptacle.
  • the sixth connector receptacle can have a greater distance from the latching counterpart to the opposite connector wall than the first connector receptacle and the second connector receptacle.
  • the sixth connector receptacle can be arranged so that both a straight line spanned by the plug contacts of the first plug receptacle and a straight line spanned by the plug contacts of the second plug receptacle intersects the fifth plug receptacle.
  • the connection part can have a printed circuit board that carries the plug contacts of at least two, preferably at least three, more preferably at least five plug receptacles of the connection part.
  • the connection part can have a sealing plate which is provided with a plurality of openings, the plug contacts of the printed circuit board being guided through the openings in the sealing plate.
  • the openings can form a seal with the circumference of the plug contacts.
  • the sealing plate can form a plate that is continuous, so that the connection part is sealed against the transfer of moisture from the free ends of the plug contacts to the printed circuit board.
  • the sealing plate can be led to the outer end of the connection part and be intended to form a sealing closure with the motor housing of an electric bicycle.
  • the connection system can include one or more dummy plugs that can be plugged into the plug receptacles as an alternative to the plugs.
  • the dummy plugs have no electrical contacts.
  • the dummy plugs can include a sealing section, a locking section and a locking tongue as described in connection with the plugs.
