1. A connector for coupling a terminal connector portion of a terminal with a cord of a peripheral device, comprising:
- a plug member capable of being coupled with the cord, said plug member including a non-pivotal first engagement claw having a first angled surface positioned to engage a first complementary angled surface of the terminal connector portion;
a lever arm pivotally mounted on said plug member and movable between a first position for coupling said connector to the terminal connector portion and a second position for uncoupling said connector from the terminal connector portion, said lever arm including a second engagement claw having a second angled surface configured to engage a second complementary angled surface of the terminal connector portion when said lever arm is in said first position; and
a biasing member disposed between said plug member and said lever arm for biasing said lever arm toward said first position with a biasing force, wherein said connector uncouples from said terminal connector portion when said second angled surface is engaged with the second complementary angled surface and a break-away force is applied from the cord to said plug member effective to overcome said biasing force and cause said second angled surface to slidingly move relative to the second complementary angled surface thereby pivoting said lever arm from said first position toward said second position without manual actuation of said lever arm.

Abstract
An electrical connector has a plug portion and a terminal portion. The plug portion is couplable to the terminal portion to provide an electrical connection between a device and a peripheral item which is securely coupled to the device during normal operation of the device. Advantageously, the plug portion will break-away from the terminal portion when a force applied to the plug portion reaches a specified magnitude to thereby prevent damage to the connector and to prevent hindering operation of the device.

9. A break-away electrical connector with an attached cord, comprising:
-
a terminal connector portion, said terminal connector portion comprising;
a terminal housing having first and second engagement lips and a first mating surface, each of said first and second engagement lips including an angled surface, and at least one terminal-side electrical contact disposed proximate said first mating surface; and
a plug connector portion adapted to be removably coupled with said terminal connector portion, said plug connector portion comprising;
a plug member capable of being coupled with the cord, said plug member having a non-pivotal first engagement claw with an angled surface configured to engage said angled surface of said first engagement lip and a second mating surface configured to interface with said first mating surface, at least one plug-side electrical contact disposed proximate said second mating surface and electrically coupled with said at least one terminal-side contact when said plug connector portion is coupled to said terminal connector portion, a lever arm pivotally mounted to said plug member and movable between a first position for coupling said plug connector portion to said terminal connector portion and a second position for uncoupling said plug connector portion from said terminal connector portion, said lever arm including a second engagement claw with an angled surface configured to engage said angled surface of said second engagement lip when said lever arm is in said first position, and a biasing member disposed between said plug member and said lever arm for biasing said lever arm toward said first position with a biasing force, wherein said plug connector portion uncouples from said terminal connector portion when said angled surface of said second engagement claw is engaged with said angled surface of said second engagement lip and a break-away force is applied from the cord to said plug member effective to overcome said biasing force and cause said angled surface of said second engagement claw to slidingly move relative to said angled surface of said second engagement lip thereby pivoting said lever arm from said first position toward said second position without manual actuation of said lever arm. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. An electrical device coupling with a cord of a peripheral device, comprising:
-
a terminal supporting a voice user interface and including a terminal connector portion with first and second engagement lips each including an angled surface, a first mating surface, and at least one terminal-side electrical contact proximate said first mating surface; and
a plug connector portion adapted to couple with said terminal connector portion, said plug connector portion including;
a plug member having a second mating surface configured to interface with said first mating surface, and at least one plug-side electrical contact proximate said second mating surface, said plug member further including a non-pivotal first engagement claw having an angled surface positioned to engage said angled surface of said first engagement lip on said terminal connector portion;
a lever arm pivotally mounted to said plug member and movable between a first position in which said plug connector portion is coupled to said terminal connector portion and a second position in which said plug connector portion is uncoupled from said terminal connector portion, said lever arm including a second engagement claw having an angled surface configured to engage said angled surface of said second engagement lip when said lever arm is in said first position, and a biasing member disposed between said plug member and said lever arm for biasing said lever arm toward said first position with a biasing force, wherein said plug connector portion uncouples from said terminal connector portion when said angled surface of said second engagement claw is engaged with said angled surface of said second engagement lip and a break-away force is applied from the cord to said plug member effective for overcoming said biasing force and moving said angled surfaces of said second engagement claw and said second engagement lip relative to each other to pivot said lever arm from said first position toward said second position without manual actuation of said lever arm. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
