Abstract

Methods, systems, and devices for a lock out device for locking a battery connector. The lock out device may include a plug having a plug end configured to engage the battery connector to prevent another connector from being connected to the battery connector. The plug may further include a lock end opposite of the plug end defining a length of the plug, the lock end having a first ring configured to receive a lock shackle. The lock out device may further include a sliding device movably coupled to the plug and having a second ring configured to receive the lock shackle. The sliding device may be configured to rotate about an axis perpendicular to the length of the plug and to slide in a direction perpendicular to the length of the plug to prevent the plug from being removed from the battery connector.

Claims (45)

1 . A lock out device for locking a battery connector comprising:

a plug having:

a plug end configured to engage the battery connector to prevent another connector from being connected to the battery connector, and

a lock end opposite of the plug end defining a length of the plug, the lock end having a first ring configured to receive a lock shackle; and

a sliding device movably coupled to the plug and having a second ring configured to receive the lock shackle, the sliding device being configured to rotate about an axis perpendicular to the length of the plug and to slide in a direction perpendicular to the length of the plug to prevent the plug from being removed from the battery connector.

2 . The lock out device of claim 1 , wherein the sliding device is further configured to slide in the direction perpendicular to the length of the plug to align the first ring and the second ring such that the first ring and the second ring may receive the lock shackle to lock a position of the sliding device relative to the plug to prevent the plug from being removed from the battery connector.

3 . The lock out device of claim 1 , wherein the plug further includes one or more protrusions along the axis perpendicular to the length of the plug, the one or more protrusions being configured to movably couple the plug to the sliding device.

4 . The lock out device of claim 3 , wherein:

the plug further includes a retainer ramp, and

the sliding device further includes:

one or more legs each having a channel configured to receive a protrusion of the one or more protrusions, and

a retainer coupled to a leg of the one or more legs and configured to engage the retainer ramp.

5 . The lock out device of claim 3 , wherein the sliding device further includes one or more legs each having:

a distal end and a proximal end opposite of the distal end, and

a channel configured to receive a protrusion of the one or more protrusions.

6 . The lock out device of claim 5 , wherein the sliding device may rotate about the axis perpendicular to the length of the plug when at least one protrusion of the one or more protrusions is adjacent to the distal end of at least one leg of the one or more legs.

7 . The lock out device of claim 6 , wherein the first ring and the second ring will align if the sliding device is positioned such that at least one protrusion of the one or more protrusions is adjacent to the proximal end of at least one leg of the one or more legs.

8 . The lock out device of claim 4 , wherein:

each channel of the one or more legs includes a narrow portion having a first width and an enlarged portion having a second width that is larger than the first width, and

the sliding device may rotate about the axis perpendicular to the length of the plug when the one or more protrusions are within the enlarged portion of at least one leg of the one or more legs.

9 . The lock out device of claim 1 , wherein the sliding device further includes one or more legs configured to engage one or more tabs of the battery connector.

10 . The lock out device of claim 9 , wherein the sliding device further includes a data connector cover coupled to at least one leg of the one or more legs and configured to receive a data plug of the battery connector.

11 . A lock out device for locking a connector of a vehicle battery comprising:

a plug configured to engage the connector of the vehicle battery to prevent another connector from being connected to the connector of the vehicle battery and having:

a first ring configured to receive a shackle of a lock,

a left side protrusion, and

a right side protrusion opposite of the left side protrusion defining a width of the plug; and

a sliding device movably coupled to the plug and having a second ring configured to receive the shackle, the sliding device being configured to rotate about the left side protrusion and the right side protrusion and to slide toward the plug to align the first ring and the second ring such that the first ring and the second ring may receive the shackle to prevent the plug from being removed from the connector of the vehicle battery.

12 . The lock out device of claim 11 , wherein the sliding device further includes one or more legs each having:

a distal end and a proximal end opposite of the distal end, and

a channel configured to receive the left side protrusion or the right side protrusion.

13 . The lock out device of claim 11 , wherein:

the plug further includes a retainer ramp, and

the sliding device further includes:

one or more legs each having a channel configured to receive the left side protrusion or the right side protrusion, and

a retainer coupled to a leg of the one or more legs and configured to engage the retainer ramp to retain a position of the sliding device relative to the plug.

14 . The lock out device of claim 13 , wherein the one or more legs are configured to engage one or more tabs of the connector of the vehicle battery.

15 . The lock out device of claim 13 , wherein:

each channel of the one or more legs includes a narrow portion having a first width and an enlarged portion having a second width that is larger than the first width, and

the sliding device may rotate about the left side protrusion and the right side protrusion when the left side protrusion or the right side protrusion is positioned within the enlarged portion of the channel of at least one leg of the one or more legs.

16 . The lock out device of claim 13 , wherein the sliding device is prevented from rotating about the left side protrusion and the right side protrusion when the left side protrusion or the right side protrusion is positioned within the narrow portion of the channel of the at least one leg.

17 . The lock out device of claim 13 , wherein the first ring and the second ring will align if the sliding device is positioned such that the left side protrusion or the right side protrusion is adjacent to the proximal end of at least one leg of the one or more legs.

18 . The lock out device of claim 13 , wherein the second ring is coupled to at least one leg of the one or more legs.

19 . The lock out device of claim 13 , wherein at least one leg of the one or more legs has a cutout portion at the distal end of the at least one leg.

20 . The lock out device of claim 13 , wherein the sliding device further includes a data connector cover coupled to at least one leg of the one or more legs and configured to receive a data plug of the connector of the vehicle battery.
