The passageway is configured to receive the cable therethrough. The body includes a flange and a seal fitting extending outwardly from the flange along the length of the body. The seal fitting includes an exterior sealing surface. The cable entry seal includes a seal conduit having a sealing end surrounding and sealingly engaged with the exterior sealing surface of the seal fitting. The seal conduit is configured to surround the cable when the cable is received through the passageway of the body. The cable entry seal includes a lock ring connected to the body. The lock ring surrounds and sealingly engages with the sealing end of the seal conduit such that the sealing end is held between the exterior sealing surface of the seal fitting and the lock ring.

A connector assembly that includes a plug connector and a receptacle connector configured to mate with each other. The plug connector has a connector body including shroud with socket contacts received therein. The shroud also includes ribs and wing guides that extend in directions that are generally perpendicular to each other. The receptacle connector has walls that define a cavity that has a complementary shape for receiving the connector body. The walls are configured to direct the connector body into the cavity such that socket contacts within the plug connector engage pin contacts within the receptacle connector. The wing guide and the rib are configured to prevent damage to the pin contacts when the connector body is erroneously inserted into the receptacle connector.

A connector that includes a main body having ends and sides with a passage extending between the ends. The passage is configured to receive at least one of conductors and cables and the main body includes a guide channel that extends from at least one end and a guide channel that extends from at least one side into the main body. The guide channels join each other at an intersection. The connector also includes a first accessory that has a projection inserted into one of the guide channels and a second accessory that has a projection inserted into another of the guide channels.

An electrical protection device for protecting an operating circuit from overcurrent and having relay contacts in series between an electrical power supply and an electrical power load and having a relay coil in parallel across the electrical power supply in an on state. The protection device includes a single relay package having a frame, the relay coil, an armature mechanically actuated from a normally closed contact position to a normally open contact position when the coil is energized, a bimetallic wiper mounted to the armature, a wiper contact mounted to the bimetallic wiper and a normally open contact, a diode connected in series with the relay coil and the normally open contact to pass coil energizing current to the coil from the electrical power supply during the on state and to prevent backflow of coil energizing current to reach the electrical power load when power is first applied to the coil, a first coil lead connected to the relay coil and a second coil lead connected to an anode of the diode, a first contact lead connected to the wiper contact, and a second contact lead connected to the normally open contact. In the on state the relay coil is connected to the electrical power supply through the diode and causes the wiper contact to connect to the normally open contact to connect the supply to the load through the first contact lead and the second contact lead. In the off state the bimetallic wiper responds to an overcurrent in the power supply path by changing shape and moving the wiper contact out of connection with the normally open contact thereby disconnecting the load from the supply.

An overcurrent protection system giving rapid response to relatively small overcurrents has a sensor element and an interruption element in series between a power source and a load. The sensor element is functionally linked to the circuit interruption element via a control element. When current exceeds a predetermined amount, the sensor element transfers heat to the control element which causes the circuit interruption element to change from a conducting state to a non-conducting fault state. The control element may include a PTC device.

Resetable overcurrent protection arrangement

An electrical device which contains a first electrode, a second electrode, a third electrode, a first resistor which is connected in series between the first and second electrodes, and a second resistor which (i) is thermally coupled to the first resistor, (ii) exhibits anomalous resistance/temperature behavior, and (iii) is connected in series between the first and third electrodes. The device has at least one of the following characteristics: (a) the first resistor and at least one of the first and second electrodes are formed from a single piece of metal; (b) the device has a generally planar configuration and comprises at least one electrical connector connected to one of the first, second, and third electrodes, whereby the first, second and third electrodes or connectors secured thereto can be secured directly to a circuit board with the device parallel to the circuit board; and (c) the second resistor is a planar sheet of a material which exhibits anomalous resistance/temperature behavior, the sheet having a first major surface to which the first and second electrodes are attached and a second major surface to which the third electrode is attached.

Circuit protection devices

An electrical protection system on a power distribution side includes a control element of a series combination of a PTC device thermally coupled with a resistive device, and a relay coil coupled with relay contacts. If the relay contacts are open the only way in which they can be closed is by supplying current to the relay coil through a resistance-capacitance network. An electronic control module on a control side includes an electronic control module for monitoring a voltage present in the system, and a switch for opening a current path feeding the system upon detection of a fault condition. An indicator indicates presence of a sensed fault condition.

Electrical protection systems

An overcurrent protection system gives rapid response to relatively small overcurrents has a sensor element and an interruption element in series between a power source and a load. The sensor element is functionally linked to the circuit interruption element via a control element. When current exceeds a predetermined amount, the sensor element transfers heat to the control element which causes the circuit interruption element to change from a conducting state to non-conducting fault state. A latching arrangement causes the protection system to remain in the non-conducting fault state until reset. The control element may include a PTC device or a bimetal switch.
