Utility power-line-jumper apparatus with external venting

摘要

A line-jumper apparatus typically includes a first connector, a second connector, and a housing attached to the first connector and the second connector. In a closed position, the housing provides a low-resistance current path and a high-resistance current path between the first connector and the second connector. In an open position, the housing inhibits current from flowing between the first connector and the second connector. The housing is configured so that, when the housing is transitioned from the closed position to the open position, the low-resistance current path is opened before the high-resistance current path. The housing typically includes a safety mechanism that prevents the low-resistance current path from being opened unless the high-resistance current path is closed.

主权项

1. A line jumper apparatus, comprising:
a housing including an intermediate assembly movably positioned therein,
a first connector attached to the housing;a second connector attached to the housing; andsaid apparatus being capable of being transitioned between a closed position and an open position, said apparatus in the closed position providing a low-resistance current path and a high-resistance current path between said first connector and said second connector through said intermediate assembly, said apparatus in the open position inhibiting current from flowing between said first connector and said second connector, and said apparatus being configured so that, when said apparatus is transitioned from the closed position to the open position, said low-resistance current path is opened before said high-resistance current path is opened;wherein said apparatus comprises a safety key mechanism, said safety key mechanism configured to: (1) prevent the intermediate assembly from being sufficiently extended in a way that breaks the low resistance current path, thereby preventing said low-resistance current path from being opened when said high-resistance current path is open, and (2) permit the intermediate assembly to be extended in a way that breaks the low resistance current path when said high-resistance current path is closed.
