Abstract

The invention relates to a modularizable electrical connection plug (100), intended to be connected to an electrical device, provided with:

• • a first element (110) comprising first electrical contacts (111),
  • a second element (120) separately comprising, on the one hand, intermediate electrical contacts (121) adapted to be connected to the said first electrical contacts (111) and, on the other hand, electrical output contacts (122) intended to be connected to electrical terminals of a current outlet,
  • means (140) for assembling the first and the second element together with one another.

According to the invention, the plug has interlocking means (150) for assembly of the first and second elements, distinct from the said assembly means.

Claims

1. A modularizable electrical connection plug (100), intended to be connected to an electrical device, provided with:

a first element (110) comprising first electrical contacts (111),

a second element (120) separately comprising, on the one hand, intermediate electrical contacts (121) adapted to be connected to the said first electrical contacts (111) and, on the other hand, electrical output contacts (122) intended to be connected to electrical terminals of a current outlet,

means (140) for assembling the first (110) and the second element (120) together with one another,

characterized in that it has interlocking means (150) for assembly of the first (110) and second elements (120), distinct from the said assembly means (140).

2. A modularizable electrical connection plug (100) according to claim 1, wherein the said interlocking means (150) can be deactivated only when the connection plug (100) is not connected to the said current outlet.

3. A modularizable electrical connection plug (100) according to one of claims 1 and 2, wherein the said interlocking means (150) are accessible only on one connecting face (123) of the second element (120) which carries the electrical output contacts (122) of the said plug (100).

4. A modularizable electrical connection plug (100) according to one of the preceding claims, wherein the said interlocking means (150) can be deactivated only by means of a key (153).

5. A modularizable electrical connection plug (100) according to one of the preceding claims, wherein the said interlocking means (150) are mechanical means having a movable lock (152) adapted to be partly seated in the said second element (120) and a recess (151A) made in the said first element (110) of the plug with which the said lock (152) is adapted to cooperate in retained relationship when the interlocking means (150) are activated.

6. A modularizable electrical connection plug (100) according to one of the preceding claims, wherein there are provided connection-blocking means (156) for preventing the connection of the electrical output contacts (122) of the plug (100) with the said electrical outlet when the interlocking means (150) are deactivated.

7. A modularizable electrical connection plug (100) according to the preceding claim, wherein the said connection-blocking means (156) have a means for retracting the said interlocking means (150) to a stable position in which these interlocking means (150) form a projection on the connecting face (123) of the said second element (120) of the plug (100) when these interlocking means (150) are deactivated.

8. A modularizable electrical connection plug (100) according to one of the preceding claims, wherein there are provided means for sealing between the said first (110) and second elements (120).

9. A modularizable electrical connection plug (100) according to the preceding claim, wherein the said sealing means are provided with a seal disposed on the said second element (120), so as to surround the said intermediate electrical contacts (121).

19. An electric motor vehicle having an electrical battery connected to a supply cable for recharging it, the end of the said cable having an electrical plug according to one of claims 1 to 9.

10. An electrical element (120) separately comprising, on the one hand, intermediate electrical contacts (121) adapted to be connected to the first electrical contacts (111) of an electrical plug of an electrical device and, on the other hand, electrical output contacts (122) intended to be connected to electrical terminals of a current outlet, and means (125, 142) for assembling this electrical element (120) together with the said plug,

characterized in that it has means (152, 151B) for interlocking the assembly of this electrical element (120) and of the said plug that are distinct from the said assembly means (125, 142), adapted to cooperate with complementary interlocking means (151A) of the said plug.

11. An electrical element according to claim 10, wherein the said interlocking means (152, 151B) can be deactivated only when the electrical element (120) is not connected to the said current outlet

12. An electrical element according to one of claims 10 and 11, wherein the said interlocking means (152, 151B) are accessible only on one connecting face (123) of this electrical element (120) which carries the electrical output contacts (122).

13. An electrical element according to one of claims 10 to 12, wherein the said interlocking means (150) can be deactivated only by means of a key (153).

14. An electrical element according to one of claims 10 to 13, wherein the said interlocking means (150) are mechanical means having a movable lock (152) adapted to be partly seated in the said electrical element (120) and adapted to cooperate in retained relationship with a recess (151B) made in the plug.

15. An electrical element according to one of claims 10 to 14, wherein there are provided connection-blocking means (156) for preventing the connection of the electrical output contacts (122) of the plug with the said electrical outlet when the interlocking means (150) are deactivated.

16. An electrical element according to the preceding claim, wherein the said connection-blocking means (156) have a means for retracting the said interlocking means (150) to a stable position in which the said interlocking means (150) form a projection on the connecting face (123) of the said element when these interlocking means (150) are deactivated.

17. An electrical element according to one of claims 10 to 16, wherein there are provided sealing means adapted to establish a sealed connection of the intermediate electrical contacts (121) of the electrical element (120) and the first electrical contacts (111) of the electrical plug.
