Abstract
Abstract A lockout device for enclosing and inhibiting unauthorized access to an electrical connector attached to an electrical cable has first and second identical joinable shell portions each with a concave interior so that when the shell portions are joined the interiors define a cavity for receiving an electrical connector. Each shell portion has a hinge pin and a hinge clevis for connection to a hinge clevis and a hinge pin, respectively, on the other shell portion to pivotally join the shell portions so that they are pivotable between open and closed positions. Male and female latch members engageable with similar members on the other shell portion are provided to hold the shell portions in the closed position. Arcuate recesses at opposite ends of the said shell portions form a circular opening, when the portions are joined, to permit a cable attached to the connector contained in the cavity to extend out of the housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
A lockout device for enclosing and inhibiting unauthorized access to an electrical connector attached to an electrical cable, the device comprising the combination of first and second shell portions joinable along edges thereof, each said shell portion having a hollow interior which, when joined with the other shell portion, defines a cavity having a central longitudinal axis for receiving said electrical connector, said first shell portion further comprising a hinge pin extending generally axially along an edge thereof, said second shell portion comprising hinge clevis means for releasably receiving said hinge pin on said first shell portion to pivotally join said shell portions so that they are movable between open and closed positions, and each said shell portion comprising latch means engageable with said other shell portion to hold said shell portions in said closed position, said latch means comprising means defining an axially opening latch recess and a protruding latch dog, said latch recess on one shell portion being positioned to receive said latch dog on said other shell portion when said portions are placed together and moved axially relative to each other.

Claim 3
Dependent Claim
34 words
A device according to claim 1 wherein each said shell portion includes and outwardly extending flange having means defining openings to receive a lock to hold said shell portions in the joined, closed position.
Claim 4
Dependent Claim
49 words
A device according to claim 1 wherein each said shell portion further comprises means defining an arcuate recess at an end of each said shell portion, said recesses of two joined shell portions forming a generally circular opening for a cable connected to said connector contained in said cavity.
Claim 5
Dependent Claim
20 words
A device according to claim 3 wherein each said shell portion includes means defining said arcuate recesses at both ends.
Claim 6
Dependent Claim
67 words
A device according to claim 1 wherein said hinge clevis means includes means defining a U-shaped recess opening in a direction opposite to the opening direction of said hollow interior and having an axial length L, said hinge pin extends axially and has a length greater than L, whereby said shell portions can be moved axially relative to each other after said pin and clevis are joined.
Claim 7
Dependent Claim
34 words
A device according to claim 5 wherein each said shell portion includes and outwardly extending flange having means defining openings to receive a lock to hold said shell portions in the joined, closed position.
Claim 8
Independent Claim
169 words
A method of enclosing an electrical connector attached to an electrical cable to inhibit unauthorized access to the connector comprising the steps of forming a pair of shell members, one said shell member having a male half-hinge on one side, the other shell member having a female half-hinge on one side, and each said shell member having axially engageable latches on the other side, a generally arcuate opening at an end and a lock opening, placing the shell members together so that the latch on each shell member is adjacent the latch on the other shell member, joining the half-hinges to form an openable and closable housing in which the lock openings are aligned in the closed position, opening the housing thus formed and inserting a connector with the cable attached thereto extending out of the housing through the arcuate openings at the end, closing the housing the enclose the connector, and inserting the shackle of a lock through the aligned openings to thereby inhibit access to the connector.
