Definitions

  • the present invention relates to electrical connection systems in general and relates, more particularly, to an electrical connection system, which can be placed on storage cells, of the container or crate type, used in the transport of perishable foodstuffs by air, maritime, rail or road.
  • the perishable food market involves very high quality transport. This very high quality translates into a certain number of requirements, including in particular the use of storage cells so as to allow efficient transport ensuring the continuity of the cold chain.
  • This market for perishable foodstuffs increasingly uses thermal protection due to regulatory requirements or technical requirements such as the pre-cooling of certain fruits and vegetables. Transport must therefore be carried out by means of a vehicle which imperatively complies with technical standards concerning the thermal insulation of the storage cell and the characteristics of the refrigeration unit.
  • a major drawback of the electrical connectors of the prior art is that they must be connected and / or disconnected manually, hence the significant risk of tearing off the electrical connectors during the loading and / or unloading of the storage cells.
  • An object of the present invention is an electrical connection system which does not have the drawbacks of the devices of the prior art.
  • Another object of the present invention is an electrical connection system which does not disturb the standard mechanical fixing or pre-existing positioning systems, lashing parts and gripping supports by clamps.
  • the invention therefore relates to an electrical connection system implemented during the loading or unloading of storage cells on or of a transport platform.
  • the electrical connection system comprises electrical connection means consisting of at least one connector of the male type and at least one connector of the female type, one being fixed to the transport platform or to the storage cell, the other being moved by a positioning element fixed to the storage cell or to the transport platform, respectively; control means, fixed to the storage cell or to the transport platform, making it possible to control the positioning element so as to establish the electrical connection between said connectors and comprising elements of the retarder type such that the control of the positioning element of the movable electrical connector is effective, when loading the storage cell, only after said storage cell is positioned on the transport platform in a predetermined position.
  • connection device of the invention is that it is automatic.
  • connection device Another advantage of the connection device is that the electrical connection is delayed over time.
  • the electrical connection system shown in FIG. 1 comprises electrical connection means 3 as well as control means 7.
  • the electrical connection means 3 consist of at least one male type connector 4 or 5 and at least a female type connector 5 or 4.
  • One of the connectors is fixed to the transport platform 2 or to the storage cell 1.
  • the other connector is moved by a positioning element 6 fixed to the storage cell 1 or to the transport platform 2.
  • the control means 7, fixed to the storage cell 1 or to the transport platform 2, make it possible to control the positioning element 6 which is associated with it so as to establish an electrical connection to the using said connectors 4,5.
  • These control means 7 are connected to the positioning element 6 by means of connection elements 9.
  • These control means 7 comprise a delay-type element 8 so that the control of the positioning element 6 of the mobile electrical connector 4 or 5 is effective, when loading the storage cell 1, only after said storage cell 1 is positioned on the transport platform in a preset position.
  • control means 7 When loading the storage cell 1 on the transport platform 2, the control means 7, owing to the fact that it is connected to the positioning element 6 by connection elements 9, is actuated in such a way that the positioning element 6 positions the mobile connector 4 or 5 in abutment against the fixed connector 5 or 4.
  • the mode of obtaining these mechanical then electrical connections will be described below, in more detail, in one embodiment, hydraulic type, control means 7.
  • FIG. 2 shows a schematic view in partial section of a preferred embodiment of the control means 7, in the rest position, connected to the associated positioning element 6.
  • the rest position is obtained when the storage cell is unloaded from the transport platform.
  • the timer piston 8 described below is then in the low position in the body of the distributor cylinder 15.
  • the control means 7 is of the hydraulic type and comprises a spring 10, a floating piston 11, a chamber 12 containing a fluid 13, a timer piston 8, the assembly being disposed in the body of the distributor cylinder 15 so as to form a hydraulic distributor device, and a return spring 14 disposed along the external rod of the timer piston 8.
  • the chamber 12 is delimited by the space included in the body of the distributor cylinder 15 by the floating piston 11 and the timer piston 8.
  • the floating piston 11 is held by the spring 10, on the one hand, and by the fluid 13, on the other hand, in such a way that the fluid is compressed.
  • the body of the distributor cylinder 15 comprises an inlet nozzle 16 and an outlet nozzle 17 for the fluid 13.
  • the chamber 12 is connected to the inlet nozzle 16 via a channel 18 formed, longitudinally from the chamber 12 and then transversely to the inlet nozzle 16, in the body of the timer piston 8.
  • the positioning element 6 can be, for example, a hydraulic cylinder with a chamber, the piston 19 of which is integral, for example, with the female connector 5.
  • the inlet nozzle 16 is connected to a non-return valve 20 (cf. 2) allowing the fluid 13 to flow only from the chamber of the positioning element 6 towards the inlet nozzle 16.
  • the timer piston 8 When loading the storage cell 1 on the transport platform 2, the timer piston 8 is actuated first and enters the body of the distributor cylinder 15 (Figure 3) to come to position in the high position ( Figure 4).
  • the supply channel 18 open on the chamber 12 and initially on the inlet nozzle 16 is positioned opposite the outlet nozzle 17.
  • the fluid 13, compressed by the spring 10 and by the timer piston 8 in the high position in the body of the distributor cylinder 15 is injected into the chamber of the positioning element 6, not shown (FIGS. 5 and 6).
  • the injection of the fluid 13 into the chamber of the hydraulic cylinder causes the female connector to move until it is in contact with the male connector.
  • the timer piston 8 When the storage cell 1 is unloaded from the transport platform 2, the timer piston 8 is actuated and moves, under the action of the return spring 14, to the low position in the body of the distributor cylinder 15 ( Figure 7) .
  • the supply channel 18 open on the chamber 12 and previously on the outlet nozzle 17 is positioned facing the inlet nozzle 16.
  • the fluid 13 in the chamber of the positioning element 6 is sucked into the chamber 12 due to the vacuum created in this chamber 12 following the displacement of the timer piston 14 from its high position to its low position.
  • the fluid 13 is also expelled into the chamber 12 from the body of the distributor cylinder 15 under the effect of the automatic return, to its rest position, of the single-acting type cylinder.
  • the speed of movement of the floating piston 11 depends on the handling system of the storage cell 1.
  • the rear speed of movement V11 of this floating piston during the injection of the fluid 13 into the chamber of the element positioning 6 is a function of the internal diameter d17 of the outlet nozzle 17 and of the pressure P10 applied by the spring 10 to the fluid 13 by means of the floating piston 11.
  • the stroke of the piston 19 of the positioning element 6 is a function of the diameter of the chamber of this positioning element and the volume of oil injected into this chamber.
  • the difference between the inlet nozzle 16 and the outlet nozzle 17 is of the order of 15 mm.
  • the electrical connectors 4,5 are connected, for example by means of electrical cables (not shown), respectively, to a cooling unit (not shown), fixed, for example, to the storage cell 1, and to an electrical power source (not shown), fixed, for example, on the transport platform 2.
  • connection system described can be used on any type of storage cell and any type of fixed or transport platform.
  • Connectors 4 and 5 are supported by a mechanical automatic coaxiality take-up system (not shown).
  • the play to be made up is of the order of plus or minus 30 mm because it is limited by the relative positions of the axis of the pin of the transport platform 2 relative to the axis of the corner piece. storage cell 1.
