Accessories are removably received by a non-contact electrical detector for measuring an electrical characteristic without galvanic contact between the accessory and a non-contact sensor in the non-contact electrical detector. In some embodiments, an accessory is positioned in a gap between first and second extensions of the non-contact electrical detector. In some embodiments, an accessory includes first and second recesses on opposite sides of the accessory. First and second clamp arms of a non-contact electrical detector are inserted within the first and second recesses to removably hold the accessory. An external conductive prong of the accessory is electrically coupled, or is selectively electrically coupleable, with an internal conductive prong of the accessory. The external conductive prong is configured to be inserted into a receptacle of an electrical outlet. In use, the accessory positions the internal conductive prong within a sensing area of the non-contact electrical sensor of the non-contact electrical detector.

A detector includes a board with a connector, a measurement resistor, a switch, and circuitry. The board with the connector is coupled to an external board. The measurement resistor is connected to the connector. The switch is connected to the measurement resistor and switches on and off an electric current flowing thorough the measurement resistor. The circuitry measures a potential difference between both ends of the measurement resistor, and determines, based on the potential difference measured, a coupling state of the external board with respect to the connector. The circuitry controls the switch to switch on and off the electric current flowing through the measurement resistor.

Example implementations involve an electrical connector and a test method of the electrical connector, wherein the electrical conduction condition between a ground member and a ground terminal can be easily confirmed while reliably contacting the ground member and ground terminal. Electrical connector involves a plurality of terminals including two types of terminals, namely, signal terminals and ground terminals; a retaining body, made of an insulating material, that arranges and retains the plurality of terminals in a condition where the signal terminals and ground terminals are intermingled; and a ground member retained by the retaining body on the inward side of the retaining body, in a condition contacting at least two ground terminals; wherein the ground member has a detecting part exposed from the retaining body in order to detect an electrical conduction condition between the ground terminals and the ground member.

A USB interface detection module includes a detection unit and an adapting device. The adapting device is electrically connected between a first electronic device and a second electronic device. According to the interface specification of the first electronic device, the voltage value of a configuration channel pin is changeable through the use of the GND_DRAIN pin and the switching action of a field-effect transistor switch. Consequently, the interface specification of the first electronic device is acquired by the second electronic device.

A testing system for electrical interconnects having a removable device under test printed circuit board (DUT PCB) that electrically connects with the electrical testing components of the system. A removable top plate is placed on top of the DUT PCB and is locked in place by a plurality of locking posts that selectively connect to cam surfaces in the top plate that pull the top plate down sandwiching the DUT PCB between the top plate and the electrical testing components of the system. An actuator is also presented that presses the device under test into the electrical interconnect at increments where tests are performed on one, some or all of the contact points of the electrical interconnect. This information is then analyzed and graphed to assist with determine the optimum force and/or height to use during actual use.
