摘要:
The present invention provides a high-speed electrical interconnection system designed to overcome the drawbacks of conventional interconnection systems. That is, the present invention provides an electrical connector capable of handling high-speed signals effectively.
摘要:
A resettable switching apparatus, useful in a GFCI receptacle, has an auto-monitoring circuit for automatically testing various functions and structures of the device. The auto-monitoring circuit initiates an auto-monitoring routine which, among other things, establishes a test fault situation on either the positive or negative half-wave of the power cycle and determines whether the detection mechanisms within the device appropriately detect the test fault and whether the device would trip in the event of an actual fault. Additional functionality of the auto-monitoring circuit permits automatic verification that the device is properly wired, that is, not miswired, and determines whether the device has reached the end of its useful life.

摘要:
A resettable switching apparatus, useful in a GFCI receptacle, has a space-efficient coaxial configuration in which a mechanical latching arrangement for resetting (i.e., closing) main switch contacts is disposed inside the trip solenoid. A movable carriage for the main contacts spans one end of the solenoid and has a latching portion in the solenoid that engages the inner end of a reset plunger in two sequential states (i.e., unlatched and latched). An electrical miswire feature is included to prevent the device from being reset until the AC power is properly connected to the device and inadvertent failure of the miswire feature due, for example, to dropping the device prior to installation is avoided. Also, an enhanced self-test, or auto-monitoring, feature is provided that is more robust than that which has been previously disclosed.

A connector latch according to the present invention is described. The connector latch comprises a generally U-shaped member having laterally extending arms, a body portion, and a spring member integral with the arms. The connector latch also includes cantilever beams projecting outwardly from the spring member. The cantilever beams deflect proportional to an applied force or load. The spring member biases against the force generated by the cantilever beams, and the arms and body portion bias against compression of the spring member. In another embodiment, a latching system is provided. The latching system includes an end cap comprising a first generally U-shaped member having a body portion. The body portion includes a first arm member, a second arm member, and a connector member having at least one of a first connector surface and a second connector surface. A connector latch is affixed to the at least one of the first and second connector surfaces. The connector latch comprises a second generally U-shaped member having outer spring loops including first end and upper surfaces, inner spring loops including second end and upper surfaces, and a spring member formed at the second upper surfaces of the inner spring loops. The latching system biases against compression produced from a compression mount type connector system.

摘要:
A GFCI device includes a latch assembly provided with a rigid electrically conducting bar connected thereto such that when a user presses a reset button the latch assembly is moved toward a pair of contacts provided as part of a reset circuit to initiate a reset operation. When the electrically conducting bar on the latch assembly connects the pair of contacts, the reset circuit is closed and an actuator is activated to place the GFCI device in the latched, reset, condition. If the GFCI device is correctly wired, the latch assembly enters the latched state. If the device is not properly wired no power is provided to the actuator and the device remains in the tripped, or open, state.
