• FIG 4 is a perspective view of the reel 7 of Figure 2, unwound cable.
• the device 7 comprises: a housing 72 and a cable 3, a first end of which is connected to a plug 74 connected to the housing 72 (carried by the housing) and present in a wall 76 thereof, and a second free end of which is connected to a plug 34 for connection to an electricity supply installation (for example 5, Figure 1).
• the plug 74 is, at least in a position of use, protruding from the wall 76 towards the outside of the housing to be connected to a socket on the vehicle side.
• the face 76 is part of a drum 722 rotatably mounted in a ring 724, the drum 722 and the ring 724 forming the housing 72.
• the cable 3 is wound around the drum 722 being contained laterally by the wall 76, defining an outer face of the housing 72, and by a wall 726 internal to the housing.
• the drum 722 is, for example, rotatably mounted around a hub 728 carried by the wall of the housing 72, opposite the wall 76 and integral with the ring 724.
• a security and control equipment 36 containing the usual elements is interposed in the path of the cable near the plug 34.
• the safety equipment 36 contains electrical protection circuits (circuit breakers, etc.). ) and load control.
• this equipment 36 adapts to the shape of the ring 724 and constitutes a portion thereof when the cable 3 is wound. According to this embodiment, a part of the cable (its plug-end end section 38) can not be wound inside because of equipment 36.
• a circumferential groove 725 in the crown is then preferably provided. 724 to receive this section 38 of cable 3 between the equipment 36 and the plug 34.
• the length of the section 38 between the plug 34 and the safety equipment is generally standardized.
• this length is a few tens of centimeters, for example of the order of 30 centimeters or less, which is perfectly suited to a reel s' registering in a diameter of a few tens of centimeters (for example, between 20 and 50 centimeters).

• bottom of the housing 14, vehicle side, has a socket 16 for receiving the plug 74 while the housing 72 is partially inserted in the housing 14.
• the plug 74 engages the body of the vehicle, the wall 76 being pressed against the body.
• an advantage of an embodiment in which the housing 72 partially engages in the housing 14 is that it improves the seal and protects the connection plug 74, taken 16.
• the socket 16 is fixed on the vehicle side, its shape serves as a key to the user performs the connection.
• FIGS. 7A and 7B are perspective views illustrating an alternative embodiment in which the plug 74 is retractable inside the housing 2.
• the plug 74 is movable in translation along an axial direction of the crown 724.
• the plug 74 is output ( Figure 7B) when the reel 7 must be connected to the vehicle 1 and is returned to the housing otherwise. This reduces the overall bulk while protecting the plug 74.
• An advantage of the embodiments described is that the fact that the housing 72 is pressed against the body of the vehicle 1, or even engaged in the housing 14, reduces the overhang or lever arm that exists in a conventional system (FIG. 1) where the cable opening from the end of the plug 32 ', generates a moment of force on the connection to the socket 12 which may damage it. Damage to the socket is particularly troublesome because it is the fixed element of the link, vehicle side, the replacement of which generates significant costs.
• reel 7 is particularly convenient to use.
• the plug 34 is connected to the installation side (5, Figure 1) and the cable is unwound by driving the housing 72 to the vehicle. Then the housing is "connected" to the vehicle 1. Once charging is complete, the user disconnects the plug 74, thus the housing, and rewinds the cable 3 by rotating the drum 722 in the crown 724, for example by using the ergot 762.
• the reel or reel being carried by the vehicle eliminates the risk of soiling occurring when a reel is placed on the ground.
• the plug 74 protruding from the reel 7 and the socket 16 corresponding to the vehicle side are plugs and special plugs for the automotive field meeting the standards in the field for use outdoors.
• the reel 7 can be easily stored in the trunk of the vehicle without losing space.
• a dry plug 16 can be provided, that is to say not electrically connected to receive the plug 74.
• the wall 76 may be fixed relative to the housing, the plug 74 being connected to the cable by rotating contacts so that rotation of the drum inside the crown does not twist the cable.
• the general shape of the reel (the shape of the crown) is not circular (for example polygonal, square, triangular, etc.). It will be noted that certain vehicles are already equipped with a housing 14 for socket 16 for connecting an electric charging cable. These housings are generally much larger in size than the size of the socket 16 to allow a user to enter the hand in the housing by manipulating a conventional plug (32 ', Figure 1). We can then plan to size the reel 7 according to the size of the existing housing 14.
• the plug 74 is not centered with respect to the housing.
• the constitution of the plug 74 is of the type of cards commonly used to be compatible with the known connections.
