DESCRIPTION OF THE EMBODIMENTS

[0045] FIG. 1 shows a vehicle 100 equipped with an assembly 50, shown in more detail in FIG. 2, comprising an electrical connection mount system 10 having an electrical connection mount 12, and a complementary electrical connection mount 40. In FIG. 1, the complementary mount 40 is connected to the mount 12. In this example, the complementary mount 40 is an outlet mount and is equipped with a handle 42, while the connection mount 12 is a connector mount. Thus, in this example, the complementary mount 40, the handle 42 and the mount 12 form a connector 70. The vehicle 100 is supplied with electrical power by the cable 80 via the assembly 50.

[0046] FIGS. 2 and 3 show the assembly 50 in perspective in a disconnected position. The outlet mount 40 is a butt contact outlet mount and has a locking element 44 configured to cooperate with the connector mount system 10 so as to lock the connection between the outlet mount 40 and the connector mount 12. The connector mount system 10 comprises the connector mount 12, which is a butt contact connector mount, and a controlled locking mechanism 14. It is noted that, in this example, in addition to having couplers 13A1/13B1 of electric power lines, the mounts also have pneumatic couplers 13A2/13B2 for gas under pressure. The presence of other couplers, electrical/electronic for example, to allow coupling other lines, such as for example data transfer lines, can also be contemplated. The mechanism 14 is configured to lock/unlock the outlet mount 40 when it is connected with the connector mount 12. In this example, the mechanism 14 cooperates with the locking element 44 of the outlet mount 40. In this example, the system 10 comprises a cowl 16 configured to protect the electrical couplings with the connector mount 12, and a front face 18. In this example, the connector mount 12, the cowl 16 and the locking mechanism 14 are assembled together with one another. The front 18 is assembled with the connector mount 12 and with the locking mechanism 14, and serves for mounting the system 10 on a frame, for example the vehicle 100. It is noted that the front 18 has a protective cowl 18A, which allows protecting the plugs of the connector mount 12 when no outlet mount is connected.

[0047] FIG. 4 shows in more detail the locking mechanism 14. The mechanism 14 has a first lever 20, a second lever 22, an electromagnet 24 and a circuit breaker 26. In this example, the first lever 20 and the second lever 22 are movable in the same plane P while the electromagnet 24, and more particularly in this example the axis X of the coil 24A of the electromagnet 24, extend in the plane P.

[0048] The first lever 20 forms a ratchet that is movable between one, locking, position (see FIG. 5) and an unlocking position (see FIG. 4). The first lever 20 has a first distal end 20A configured to cooperate with an outlet mount 40, for example with the locking element 44, and a second distal end 20B configured to cooperate with the second lever 22. The first lever 20 has a first axis of rotation 20C around which the first lever 20 pivots. In this example, the first distal end 20A and the second distal end 20B are arranged on the same side with respect to the first axis of rotation 20C. In this example, the first lever 20 has substantially a “U” shape, the axis of rotation 20C being arranged in the base of the “U” shape. The “U” shape has a first arm 21A having the first distal end 20A and a second arm 21B having the second distal end 20B. Any other shape of the lever can be contemplated for the first lever 20.

[0049] In this example, the distance D1 between the first distal end 20A and the first axis of rotation 20C is smaller than the distance D2 between the second distal end 20B and the first axis of rotation 20C. In this example, D2 is greater than three times D1. More precisely, in this example D1=8.5 mm and D2=32.5 mm.

[0050] The first lever 20 has a lug 21 configured to cooperate with a strip 26A of the circuit breaker 26, whereby the circuit breaker 26 cuts the electric power supply circuit (not shown) of the electromagnet 24 when the first lever 20 is in the unlocking position and closes the electric power supply circuit of the electromagnet 24 when the first lever 20 is in its locking position. In this example, the lug 21 presses on the strip 26A in the locking position and does not press on the strip 26A in the unlocking position. In other words, in the resting position, the circuit breaker 26 is configured to open the electric power supply circuit of the electromagnet 24.

[0051] The first lever 20 is mounted on a first return element 28, a torsion spring 28 in this example, one end of which cooperates with a casing 30 and one end cooperates with the lever 20 (also see FIG. 6). The first return element 28 tends to return the first lever 20 from the locking position to the unlocking position.

[0052] The second lever 22 has a third distal end 22A forming a hook and configured to cooperate with the first lever 20 in the locking position, in this example with the first distal end 20A of the first lever 20. The second lever 22 is movable between a hooking position (FIGS. 4 and 5, position in a continuous line in FIG. 6) in which it is configured to block the first lever 20 in the locking position and a liberation position (position in a dashed line in FIG. 6) in which it is configured to free the first lever 20. In this example, the first lever 20 and the second lever 22 cooperate directly.

[0053] The second lever 22 has a fourth distal end 22B coupled with the electromagnet 24. The second lever 22 has a second axis of rotation 22C around which the second lever 22 pivots. In this example, the third distal end 22A and the fourth distal end 22B are arranged opposite to one another with respect to the second axis of rotation 22C. In this example, the second lever 22 has a substantially rectilinear shape. Any other shape of the lever can be contemplated for the second lever 22.

[0054] In this example, the distance D3 between the third distal end 22A and the second axis of rotation 22C is smaller than the distance D4 between the fourth distal end 22B and the second axis of rotation 22C. In this example, D4 is greater than two times D3. More precisely, in this example D3=11.5 mm and D4=27.1 mm.

[0055] The second lever 22 is mounted on a second return element 32, in this example a torsion spring 32, of which one end cooperates with the casing 30 and one end cooperates with the lever 22. The second return element 32 tends to return the second lever 22 from the liberation position to the hooking position.

[0056] The electromagnet 24 has a coil 24A with axis X and a sliding rod 24B extending partially within the coil 24A and coupled via a prong 25 with the fourth distal end 22B of the second lever 22. When the electromagnet 24 is activated, i.e. when it is supplied with electrical power, the rod 24B is moved, in this example the rod 24A is pulled toward the interior of the coil 24B along arrow F1 (see FIG. 4), along the axis X. This has the effect of pivoting the second lever 22, whereby the second lever 22 passes from the hooking position to the liberation position, which consequently liberates the first lever 20 when it is in the locking position. In this example, the electromagnet 24 has a duty factor of 6%.

[0057] The locking mechanism 14 comprises a manual mechanical unlocking control 34, in this example a push-button 34. The push-button 34 has a cam 34A configured to cooperate with a cam surface 22D of the second lever 22. Thus, when the push-button 34 is pushed manually via the button 34B along the arrow F2 (see FIG. 4), the cam 34A presses against the cam surface 22D, which has the effect of moving the second lever 22 from the hooking position to the liberation position, consequently freeing the first lever 20 when it is in the locking position. It is thus possible to move the first lever 20 from the locking position to the unlocking position. A return spring 37 allows returning the push-button 34 into its initial position, namely the position where the cam 34A allows the second lever 22 to remain in the hooking position.

[0058] During the connection of the connector mount 12 with the outlet mount 40, the locking element 44 engages with the first lever 20. In this example, the first lever 20, which is by default in the unlocking position because of the first return element 28, has the “U” shaped opening oriented toward the insertion orifice 35 of the casing 30 configured to receive the locking element 44. Thus, during the insertion of the locking element 44, the latter engages within the “U” of the first lever 20, and presses the second arm 20B while the first arm 20A engages with the locking element 44. This is shown in FIG. 6. The first lever 20 thus passes from the unlocking position to the locking position, in which the first lever 20 locks the outlet mount 40 in connection with the connector mount 12. In this example, the first arm 21A cooperates with the locking element 44, and is engaged in the loop formed by the locking element 44 so as to block the locking element 44, and therefore the outlet mount 40.

[0059] When passing from the unlocking position to the locking position, the second distal end 20B of the first lever 20 cooperates with the third distal end 22A of the second lever 22, which is pushed from the hooking position to the liberation position (position in a dashed line in FIG. 6), whereby the second end 20B engages with the third end 22A. The latter forming a hook, it hooks the second distal end 20B when returning to the hooking position, its default position due to the return element 32. This configuration is shown in FIG. 5.

[0060] The first lever 20 is thus held in the locking position by the second lever 22. In this position, the lug 21 presses on the strip 26A of the circuit breaker 26, whereby the electrical power supply circuit of the electromagnet 24 is closed. It therefore becomes possible to actuate the electromagnet 24.

[0061] According to a first example, to unlock the outlet mount 40, the electromagnet 24 is actuated, i.e. it is supplied with electrical power, for example when the vehicle 100 is started. The rod 24B then pulls on the second lever 22, which passes into the liberation position, which has the effect of freeing the first lever 20. The locking element 44 is then no longer locked by the first lever 20, the outlet mount 40 is ejected from the connector mount 12 due to the springs, not shown, of the butt contacts. The element 44 thus disengages from the first lever 20, and the latter is returned into the unlocking position by the return element 28. The lug 21 then ceases to cooperate with the strip 26A of the circuit breaker 26, the latter thus cutting the electrical power supply of the electromagnet 24. The rod 24B becomes free to move in the axial direction X, and the second return element 32 returns the second lever 22 into the hooking position. This configuration is shown in FIG. 4.

[0062] According to a second example, to unlock the outlet mount 40, manual control 34 is actuated, i.e. the button 34B is manually pressed. This has the effect of moving the second lever 22 into the liberation position. Then, in a similar manner to what has been described in the scope of the first example, the first lever 20 returns into the unlocking position and the outlet mount 40 is ejected. When the pressure exerted on the button 34B is released, the latter returns into its initial position due to the spring 37 and the second lever 22 returns into the hooking position due to the second return element 32.

[0063] Although the present invention has been described by referring to specific embodiments, it is obvious that modifications and changes can be carried out on these examples without departing from the general scope of the invention as defined by the claims. In particular, individual features of the different embodiments illustrated/mentioned can be combined into additional embodiments. Consequently, the description and the drawings must be considered in an illustrative, rather than a restrictive sense.

[0064] For example, the electrical connection mount 12 can be an outlet mount instead of a connector mount, while the complementary electrical connection mount 40 can be a connector mount instead of an outlet mount. According to another example, the mounts can be of the socket contact types rather than butt contact types.
