An unauthorized connection detecting device to detect an unauthorized device connection at a connection part at which an electronic control unit mounted on a vehicle and an input and output unit are connected to each other is provided. The unauthorized connection detecting device includes a pair of connectors having one connector mounted on the electronic control unit and another connector mounted on the input and output unit, the pair of connectors being to be attached to each other, a protrusion or a conductor pattern formed on the another connector, a switch unit arranged on the one connector and to detect the protrusion or a conductor connection detecting unit arranged on the one connector and to be electrically connected to the conductor pattern, and an unauthorized connection identification unit to detect an unauthorized connection based on a state detected by the switch unit or the conductor connection detecting unit.

The present invention provides a receptacle connector including: a grounding portion configured to ground a connection object; and a ground connection terminal that is configured to be switchably held in a first state in which the ground connection terminal is electrically separated from the grounding portion, or in a second state in which the ground connection terminal is electrically brought into conduction with the grounding portion. The ground connection terminal is switched between the first state and the second state in operative association with interlining of the plug connector and the fitting portion. In the first state, the grounding terminal and the grounding portion are electrically separated. In the second state, the grounding terminal and the grounding portion are electrically brought into conduction with each other through the ground connection terminal.

An audio jack may include two contacts to electrically connect to a ground contact of an audio plug in order to detect that a metallic audio plug is inserted into the audio jack. A first of these two contacts may be grounded to form a current return path that generates a ground voltage at the ground contact of the audio plug. The second of these two contacts may be repurposed after the detection to sense the ground voltage. The sensed ground voltage may be added to right and left audio signals. The net voltages provided to the audio plug may be right and left audio signals that include the sensed ground voltage minus the actual ground voltage at the ground contact of the audio plug. This may remove the ground voltage from the net audio output signals, which may reduce crosstalk.

A wall mountable connector for securing a thermostat to a wall is disclosed. The wall mountable connector may include built in jumper functionality. In some cases, the wall mountable connector may include a plurality of wiring terminals as well as structure enabling an installer or other person to easily electrically connect (e.g. jumper) one or more of the wiring terminals in order to accommodate different equipment installations. For example, in some cases there may be a desire to electrically connect (e.g. jumper) or disconnect certain wiring terminals that correspond to transformer input terminals, which in some equipment installations are intended to be independently powered while in others they are not.

In some cases, the wall mountable connector may include a slider with a cam that selectively lifts a conductor to disconnect two or more wiring terminals. The wall mountable connector may also include structure that helps prevent electrically connecting field wires to particular wiring terminals in error, depending on the position of the slider.

Telecommunications jacks and methods of their use and construction are described. One telecommunications jack is adapted to receive a plug, and includes a housing defining a port for receiving the plug, as well as first, second, third, fourth, fifth, sixth, seventh and eighth consecutively arranged contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing along a first axis. The jack includes first, second, third, fourth, fifth, sixth, seventh and eighth wire termination contacts for terminating wires to the jack, and a circuit board arrangement including first and second circuits, the circuit board arrangement including a circuit board moveable in a direction non-parallel with the first axis between first and second positions. In the first position the circuit board electrically connects contact springs to wire termination contacts in a first configuration, and in the second position the circuit board connects contact springs to wire termination contacts in a second configuration.

An interface includes a connector that is physically and electrically connectable to a device conforming to a first interface standard and a device conforming to a second interface standard, and an interface circuit including a signal line extending to a terminal of the connector, a coupling capacitor disposed on the signal line, and a switch having a first end electrically connected to a first terminal of the coupling capacitor and a second end electrically connected to a second terminal of the coupling capacitor. The switch is turned on when the connector is connected to a device conforming to the first interface standard so that a signal bypasses the coupling capacitor and is transmitted through the switch and turned off when the connector is connected to a device conforming to the second interface standard so that the signal is transmitted through the coupling capacitor.

The present disclosure provides a connector for coupling a first electronic device and a second electronic device with a power source to enable the power source to provide a current to the first electronic device and the second electronic device, the connector includes: a first connector component; a second connector component; a third connector component; a power line coupled with the first connector component, the second connector component, and the third connector component; a first data line; and a signal switching circuit, configured to: detect whether the third connector component is coupled with the power source; control the first connector component and the second connector component to be coupled when it is not detected that the third connector component is coupled with the power source; and when it is detected that the third connector component is coupled with the power source: control the first connector component and the third connector component to be coupled, to send a power source connection message to the first electronic device via the first data line; or control the second connector component and the third connector component to be coupled, to send a power source connection message to the second electronic device via the first data line.

Remote management of network interface peripheral cards uses physical pin reassignment and a dedicated management network. One or more physical pins in a connector may be dynamically redefined from an interface protocol to a different interface protocol. The dynamic redefinition allows existing input/output signals to be routed to the pins to provide remote management features.
