The socket 100 also includes a protective hand for the connectors 102-118. Paragraphs to: protect the operator from electric shock and/or protect the connector from external erosion, such as from corrosion.

In the illustrated embodiment, the protection means comprises an assembly of two wall members 128 and 130 shown in FIG. 2, which is mounted to a spring 132 that is securely fastened to the socket 100, particularly a coupling recess In the base of 120. The assembly formed by the two wall members 128-130 can be translated in the coupling recess 120 by applying pressure in a direction perpendicular to the plane in which the wall members are formed. The wall member 128 is located below the wall member 130, that is, closer to the base wall 122 of the coupling recess 120. The wall member 130 is mounted in a non-rotatable manner relative to the socket 100, and the wall member 128 is rotatably mounted relative to the wall member 130.

Alternatively, the wall member 128 can be mounted in a non-rotatable manner, and the wall member 130 can be mounted in a rotatable manner relative to the wall member 128.

When the assembly formed by the two wall members 128 and 130 is translatable in the socket, and particularly in the coupling recess 120, the wall member 128 is rotatable relative to the wall member 130, for example It is rotated by pushing the power plug of the notch 120. According to an embodiment, the wall member 128 is rotatable via a torsion groove (not shown) provided on the inner surface of the coupling recess 120.

In the illustrated embodiment, wall members 128 and 130 each have a through hole for each connector 102 to 118 that allows access to the connectors 102-118.

At this level In the closed position, the connectors 102 to 118 are not allowed to be accessed, which are protected in a sealed manner. This closed position is achieved when the assembly of wall members 128 and 130 is in the standby position, i.e., when the translational motion is not being performed, and is remote from the base wall 122.

In a second position, referred to as an open position, obtained by rotating the wall member 128 relative to the wall member 130, the through-hole facing wall member 130 associated with the connectors 102-118 is associated with the connectors 102-118.

The wall member 230 is mounted in a non-rotatable manner, and the wall member 228 is rotatably mounted relative to the wall member 230. Alternatively, the wall member 228 can be mounted in a non-rotatable manner, and the wall member 230 can be mounted in a rotatable manner relative to the wall member 228.

The wall members 228 and 230 each have a through hole for allowing the connectors 202 to 218 to be accessed.

In a position referred to as the closed position, the wall member 228 is positioned such that the through hole associated with the wall member 228 and the connectors 202-218 is displaced relative to the through hole associated with the wall member 230 and the connectors 202-218. . In this closed position, access to connectors 202 through 218 is not permitted, which is protected in a sealed manner.

In a second position, referred to as an open position, which is obtained by rotating the wall member 228 relative to the wall member 230, the wall member 228 associated with the connectors 202 to 218 has a through-hole facing wall member 230 associated with the connectors 202-218. The through holes are connected to allow access to each of the connectors 202 to 218. In this position, each connector 202-218 can be mated with a connector of a power outlet.

In particular, the plug 200 includes a cavity 234 (FIG. 6) disposed in the wall member 228 and accessible from the wall member 230 using the opening 236 provided in the wall member 230. A cavity 234 is provided for receiving a male drive of the power outlet, such as the fingers 134 of the receptacle 100 described above, which are received in the cavity 234. Thus, when the plug 200 is nested within the receptacle 100, the fingers 134 are received in the cavity 234. Pushing the plug 200 centrally into the socket 100 causes the wall member 128 of the socket 100 to rotate, thereby rotating the fingers 134 and securely securing to the wall member 128. As the finger 134 engages the cavity 234 of the wall member 228, it drives the cavity 234 as the opening 136 rotates, causing the wall member 228 of the plug 200 to rotate relative to the wall member 230 to bring it into the open position, wherein the wall The respective through holes of members 228 and 238 are aligned and allow access to connectors 202 through 218.

Similarly, the connectors 102-118 of the receptacle 100 are connected to one or more cables that are routed into the power outlet 100.

In the embodiment of Figures 6 through 9, the power plug 200 has a circular outer cross section, particularly at the top of the plug 220.

Moreover, supply connectors 202-204 and ground/earth connector 206 are placed on a circular path at a constant 72[deg.] angular pitch that is the same center as circular cross-section 220 of plug 200.

In addition, the complementary connectors 208 to 218 are placed in pairs at a constant 72° angular pitch in the center of the top section of the center and plug 220, and the paths of the upper supply connectors 202 to 204 and the ground connector 206. The center is on the same circular path.

In addition, the supply connectors 202-204 and the ground connector 206 are alternately placed on the one hand, and the complementary connectors 208-218, on the other hand, such that the supply (or ground) connector has a pair of complementary sides on each side. Connector.

The power plug 200 can be placed at the end of a charging line located on the electric vehicle or on the charging station.

Alternatively, the power plug 200 can be fixedly placed on a vehicle or charging station.

Of course, the invention is not limited to the embodiments detailed above. For example, alternatively, a coupling recess can be provided on the plug instead of the socket, the latter having a male coupling.

In addition to the above, instead of the socket, at least one connector of the plug may be a female or male connector, respectively.

In addition, the socket and the plug may respectively comprise more than two supply connector groups, each group being associated with an independent supply signal.

The number and function of the complementary connectors can be different from the above.

The position of the at least one connector may be different from the position described in the embodiment.

In particular, the number of storage modules is not limited to the number given in the embodiment, and corresponds to the maximum number of electrical energy storage modules, especially depending on the weight and operating range of the vehicle for consideration of the vehicle operation. .
