An embodiment of a vehicle 50 is described below with reference to Figures 1 to 3. The vehicle is preferably of the automotive type with thermal or electric or hybrid motorization. The vehicle 50 comprises a device 100 for encapsulating a battery 1. The device 100 comprises an enclosure 10, the enclosure 10 comprising a housing 11 and a cover 12. The housing 11 and the cover 12 form a housing 110 for receiving of the battery 1. When the cover 12 closes the case 11, the housing 110 is sealed against liquids and dust. The enclosure 10 is formed from an electrically insulating material. In the case of a vehicle with thermal motorization, the battery is for example a battery supplying electrical equipment of the vehicle.

The device 100 comprises a first electric line 2 connecting a first terminal 201 of the battery 1 to a first element or electric line output terminal 5. The device 100 comprises a second electric line 3 connecting a second terminal 202 of the battery 1 to the circuit breaker 30. A first wired connection 41 connects the second electrical line 3 to the circuit breaker 30. The device 100 comprises a third electrical line 4 connecting the circuit breaker 30 to a second electrical line output element or terminal 6. A second wire connection 42 connects the third electric line to the circuit breaker 30. The first and the second electric line output elements 5, 6 are intended to preserve the tightness of the housing 110. To do this, these elements are integrated in a wall of the enclosure, in particular in a wall of the casing and / or of the cover. They provide a galvanic connection between the inside and the outside of the enclosure. The circuit breaker 30 comprises a first electrical contact 31, in particular a first male electrical contact 31. The first electrical contact 31 is integral with the actuating element 34. The first electrical contact 31 is mounted so as to be mobile, in particular mobile in translation and / Or in rotation with respect to a first insulating ring 21 andlor with respect to the enclosure. The first electrical contact 31 generally has a cylindrical shape made of conductive material. It is in particular formed of a conductive shaft made of copper or a copper alloy or even of any other conductive material. The gripping element 36 is fixed on a part of the driver shaft outside the enclosure 110. The circuit breaker 30 comprises a second electrical contact 32, in particular a second female electrical contact 32. The second electrical contact 32 has the overall shape of a ring or the arc of a ring. The second electrical contact cooperates with the first electrical contact 31 by sliding relative to each other. The second electrical contact 32 is mounted in a second insulating ring 22 and / or is mounted fixed relative to the enclosure. The second insulating ring 22 is mounted in the casing 11 and / or in the cover 12. The second insulating ring 22 is advantageously cylindrical in shape. The circuit breaker 30 comprises a third electrical contact 33, in particular a third female electrical contact 33. The third electrical contact 33 has the overall shape of a ring or of the arc of a ring. The third electrical contact cooperates with the first electrical contact 31 by sliding relative to each other. The third electrical contact 33 is mounted in a third ring insulation 23 and / or is mounted fixed relative to the enclosure. Third insulating ring 23 is mounted in housing 11 and / or in cover 12. Third insulating ring 23 is advantageously cylindrical in shape. The second and third electrical contacts 32, 33 are made of electrically conductive material so as to be in electrical contact when the first electrical contact 31 cooperates therewith. Advantageously, the second and third electrical contacts 32, 33 comprise a conductive leaf spring so as to maintain galvanic contact with the first electrical contact 31 when the first contact is introduced at the level of the first and second contacts. The circuit breaker 30 is arranged in a bore in a wall of the housing. Advantageously, the circuit breaker 30 is arranged in a bore arranged opposite the cover 12. The first electrical contact 31 is mounted mobile, in particular mobile in translation and / or in rotation relative to the second electrical contact 32 and to the third electrical contact 33. The electrical contacts are arranged so that the first electrical contact 31 has a first position corresponding to a first position of the actuating element, in which the second and third electrical contacts 32, 33 are each electrically connected to the first electrical contact 31 In this configuration, terminal 202 is electrically connected to terminal 5. Furthermore, the first electrical contact has a second position corresponding to a second position of the actuating element, in which at least one of the second and third electrical contacts is not electrically connected to the first electrical contact 31. The passage from the first position of the actuating element to the second position of the actuating element or vice versa, is preferably done by a translational movement of the first electrical contact 31 along its axis. The actuating element 34 may comprise an electric actuator 70 illustrated in FIG. 2. The electric actuator 70 is able to actuate the circuit breaker 30 without manual intervention. According to one embodiment, the electric actuator 70 is able to move the actuating element 34 from its first position to its second position and, conversely, it is able to move the actuating element 34 from its second position to its first position. The electric actuator 70 changes the position of the actuating element 34 for example by the activation of an electric coil. According to the alternative embodiment illustrated in FIG. 3, a second electronic circuit breaker 63 is arranged in the enclosure 10. The second electronic circuit breaker 63 comprises a first and a second relay 61, 62. The first relay 61 is intended to open or close the first electrical line 2 and the second relay 62 is intended to open or close the third electrical line 4. The second circuit breaker 63 also comprises a control unit 60 of the first and second relays. The second electronic circuit breaker 63 is capable of breaking the electric circuit of the battery 1 independently of the circuit breaker 30, for example on an order from a control unit 55 of the vehicle 50. The first and the second relays 61, 62 are controlled opening relays, that is to say that in the absence of electronic control the contacts of the relays 61, 62 are closed. The operation of device 100 is now described below with reference to Figure 1. Let us consider a vehicle 50 comprising a device 100 and a battery 1 placed in the enclosure 10 of the device 100. The battery 1 is connected to the first and to the second electrical lines 2, 3. When the actuating element 34 is in function position or activated position, the first electrical contact 31 is in the first position, thus making it possible to electrically connect the second electrical line 3 with the third electrical line 4. In the alternative embodiment, in addition to the actuating element in function , the second circuit breaker 63 must be in the functional configuration, that is to say that the control unit 60 does not electrically energize the first and the second relays 61, 62. When the battery 1 supplies the electrical and / or electronic circuit of the vehicle 50, it is possible to cut off the electrical supply coming from the battery 1 using the circuit breaker 30. The power supply is cut off by activating the cut-out. circuit using the manual gripping element 36 so as to place the first electrical contact 31 in the second position and thus cut the electrical connection between the second electrical line 3 and the third electrical line 4. The actuating element 34 is also controlled by the electric actuator 70. For example, when the electric actuator 70 is supplied with electricity, an electric current is established in a coil placed in the electric actuator 70. This coil created a magnetic field capable of causing the position of the actuating element 34 to change. According to the alternative embodiment, it is also possible to control the cut-off of the power supply from the battery 1 using the second electronic circuit breaker 63. When the second electronic circuit breaker is activated, it opens the first and the second relay 61, 62 thus cutting off the electrical power supply from battery 1. Advantageously, the encapsulation device 100 makes it possible to cut off or switch on the power supply coming from a battery 1 while keeping the battery in a sealed housing 110 .
