Abstract
Abstract A terminator system for coaxial cable and the like is comprised of a theft-proof terminator unit and a complementary installation tool coacting with the terminator unit for rapid installation and removal. The terminator unit includes a cylindrical housing, a plug loosely mounted in the housing for rotation relative thereto, a rotary drive member also mounted in the housing in spaced relationship to the plug and adapted for movement into engagement with the plug for imparting rotary motion thereto, and a spring constantly urging the rotary drive member out of driving engagement with the plug. The complementary installation tool is a reusable device including an elongated semicircular mounting member for holding the terminator unit during installation and removal and a drive stem on the terminator mounting member operative for driving the rotary drive member into engagement with the plug against the bias of the spring while the terminator is held by the terminator and for rotatably connecting the plug to the member being terminated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
190 words
An electrical terminator system for preventing unauthorized connection to coaxial cable, tap devices and similar electrical terminals comprising an electrical terminator unit and a complementary installation tool coacting with the electrical terminator unit for rapid installation and removal thereof, said electrical terminator unit including a housing, a plug loosely mounted in the housing adjacent one end thereof for rotation relative thereto, said plug including a resistive load and having rotary connecting means for connection to a terminal being terminated, a rotary drive member mounted in the housing in spaced relationship to said plug and adapted for movement toward said one end into engagement with said plug for imparting rotary motion thereto to connect the plug to said terminal and biasing means urging said rotary drive member out of driving engAgement with said plug, said installation tool including a terminator mount cooperating with said terminator housing and holding the terminator unit and a drive stem on the terminator mount operative for driving said rotary drive member toward said one end into engagement with said plug against the bias of said biasing means while the terminator unit is held by the mount.
Claim 2
Dependent Claim
190 words
An electrical terminator system for preventing unauthorized connection to coaxial cable, tap devices and similar electrical terminals comprising an electrical terminator unit and a complementary installation tool coacting with the electrical terminator unit for rapid installation and removal thereof, said electrical terminator unit including a housing, a plug loosely mounted in the housing adjacent one end thereof for rotation relative thereto, said plug including a resistive load and having rotary connecting means for connection to a terminal being terminated, a rotary drive member mounted in the housing in spaced relationship to said plug and adapted for movement toward said one end into engagement with said plug for imparting rotary motion thereto to connect the plug to said terminal and biasing means urging said rotary drive member out of driving engAgement with said plug, said installation tool including a terminator mount cooperating with said terminator housing and holding the terminator unit and a drive stem on the terminator mount operative for driving said rotary drive member toward said one end into engagement with said plug against the bias of said biasing means while the terminator unit is held by the mount.
