Abstract:
A combination apparatus combined by a Bluetooth headset and a charging holder includes a Bluetooth headset and a charging holder capable of connecting to power supply, the charging holder includes a main body, at one end of the charging holder is an electrically connecting part connected to DC power supply, and at the opposite end is a socket part for seating the Bluetooth headset, and there is an electric-contact adapted to the electric-contact at the bottom of the Bluetooth headset.
Abstract:
An improved voice transmitter-receiver, a plug of which has a clamping portion at a front end thereof, and a connecting socket is located on an electronic device. A mounting hole is located at an outer side of the connecting socket, thereby enabling the voice transmitter-receiver to use the plug to plug into the connecting socket of the electronic device and clamp into the mounting hole of the connecting socket by means of the clamping portion on the plug, thus connecting and fixedly locking the voice transmitter-receiver to the electronic device to prevent the plug of the voice transmitter-receiver from being inadvertently pulled out or coming away from the connecting socket of the electronic device.
Abstract:
A method is provided for tuning the characteristic impedance of an electrical switching connector (12). A pair of switch terminals (24,26) are provided with operatively engageable contact portions (24c,26c). A pair of ground terminals (28,30) are juxtaposed alongside the switch terminals. The spacing (A-F) between at least one of the ground terminals and one of the switch terminals is adjusted to adjust the capacitance therebetween and, thereby, adjust the impedance of the connector. An overlapping area (36,36A,36B) between one of the switch terminals and one of the ground terminals can be adjusted to adjust the capacitance therebetween and, thereby, adjust the impedance of the connector.
Abstract:
PROBLEM TO BE SOLVED: To provide a grounding terminal capable of reducing size, aiming at improvement of an electric connection property with a body of equipment. SOLUTION: The polygon-shaped grounding terminal 5 to be mounted on the surface of a printed board 2 at the position of a mounting hole 2a has a plurality of connection parts 5j formed on the inner periphery of a mounting hole 5a, keeping a distance from each other in a peripheral direction, extending toward the center of the terminal.
