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.

Systems ( 100 ) and methods ( 1400 ) for detecting removal and attempted removals of an electronic component from an electronic device. The methods comprising: disposing the electronic component ( 112 ) on the electronic device such that a conductive surface of the electronic component contacts a ground conductor ( 802 ) disposed on a first surface ( 812 ) of an internal circuit board ( 500 ); using an electro-mechanical member ( 700 ) to mechanically couple the electronic component to the internal circuit board and to create an electrical path from the ground conductor to a sensing conductor ( 800 ) disposed on a second surface ( 814 ) opposed from the first surface of the internal circuit board; and sensing a break in the electrical path.

The invention relates to a coaxial connector (COAX _ CON) for terminating a coaxial cable (COAX _ CAB), wherein the coaxial connector (COAX _ CON) comprises means for connecting an inner conductor (lC_COAX_CAB) and an outer conductor (OC_COAX_CAB) of the coaxial cable (COAX_CAB) and wherein an outer conductor (OC_COAX_CON) of the coaxial connector (COAX _ CON) comprises means for connecting a grounding cable (G _ CAB). The invention further relates to a coaxial cable (COAX _ CAB) with a grounding cable (G_CAB) and a coaxial connector (COAX_CON) and to base station for use in a radio communication system comprising the coaxial cable (COAX_CAB) with the grounding cable (G_CAB) and the coaxial connector (COAX_CON).
Abstract:
A ground terminal (5) capable of being downsized and having good electrical connectability with a chassis. The ground terminal (5) includes a ground terminal body (5') formed into an annular shape as viewed in plan, and at least one connection portion (5j) formed integrally with the ground terminal body (5'), the connection portion (5j) being bendable and extending from an inner circumference of the ground terminal body (5') toward the center of the ground terminal (5). When a mounting screw used to mount a printed board (2) mounted with the ground terminal (5) to a chassis is inserted into the annular ground terminal body (5') and a mounting hole (2a) of the printed board (2), the connection portion (5j) of the ground terminal (5) is bent in the mounting hole (2a) to be brought in contact with the chassis.
Abstract:
Coaxial connector provided with a body (20) of electroconductive material which extends in the casing (1) of the connector between the connection ends (18, 19) and is electrically separated therefrom. The body (20) functions as a capacitive coupling medium between the connection ends (18, 19) and thus influences the electrical connection impedance of the connector. Because a body of magnetic material (21) is accommodated at the same time, an inductive coupling can be provided and frequency-dependent impedance matching is possible.

An example cable assembly includes a coaxial cable. A layer encases at least part of the coaxial cable. A memory on, or in contact with, the layer, the memory is configured to store calibration data for the coaxial cable.
Abstract:
The present invention includes a plug bolt and a bolt seat. The plug bolt includes a bolt pin having a receiving hole that receives a circuit device including an RFID chip electrically connected with a main circuit and a radiation unit. The receiving hole defines a hole body arranged in an axial direction, and an open hole bottom at a bottom of the hole body. The main circuit includes a lower contact point. The radiation unit induces an effect of coupling feed with respect to the hold body to make the bolt pin forming an upper monopole antenna. The bolt seat includes a lower monopole antenna and a locking hole into which the bolt pin is insertable. When the lower monopole antenna is electrically connected with the lower contact point, the upper and lower monopole antennas jointly form a standard dipole antenna to emit a signal that is monitorable.
