A connector 10 is provided with electrically conductive inner conductors 11, an outer conductor 13 made of die casting for surrounding the inner conductors 11, an insulating housing 14 into which the outer conductor 13 is mounted, and a coupling member 15 for coupling the outer conductor 13 and the housing 14 to each other.

A board-to-board plug, comprising an insulating seat (20) integral to a metal insert (30), several signal terminals (40) arranged inside the insulating seat (20), and a shielding housing (10) coated outside the insulating seat (20). The insulating seat (20) comprises an engagement end (21) provided with terminal slots (214), terminal blocks (24) formed by extending from the engagement end (21) to the rear direction, and a pair of extension arms (22) formed by extending from both transverse sides of the terminal block (24) to the rear direction. The metal insert (30) comprises a board body portion (31) formed between a pair of extension arms (22), and several grounding terminals (37) bent from the front end of the board body portion (31) and extending into the terminal slots (214). The grounding terminals (37) and the signal terminals (40) are arranged at intervals.

An ultra-low profile coaxial cable connector (i.e. plug) is provided that implements a lateral coupling of a coaxial cable inner conductor and center pin of a mating PCB-mounted coaxial receptacle. The overall height of a mating coaxial receptacle center pin is also reduced by way of a cutout in the receptacle ground ring as well as a cutout in a mating outer shell of the coaxial cable connector. The ultra-low profile coaxial cable connector achieves a reduction in mated height of less than 1.0 mm for both 1.13 mm diameter and 0.81 mm diameter coaxial cables. In both cases, the coaxial cable connector designs as discussed herein enable a further reduction in the total thickness of communication module boards to 1.25 mm, thereby meeting the high demands for thinner electronic device designs.

A communication apparatus having a monitoring function for a coupling state of a connector and/or a method of controlling the communication apparatus are provided. According to various example embodiments, a communication device may include an RF connector portion detachably coupled with a cable connector portion of one end of a cable for transmitting an antenna signal, at least one capacitor disposed near the RF connector portion, and a controller (comprising circuitry) for monitoring a coupling state between the cable connector portion and the RF connector portion based on a capacitance of the at least one capacitor.

A device that includes a first board, a second board, and coaxial cable coupled to the first board and the second board. The coaxial cable includes a multi-line coaxial cable configured to provide at least two electrical paths for electrical currents between the first board and the second board. A first plug is coupled to the first board. A second plug is coupled to the second board. The coaxial cable includes a first receptable and a second receptable. The first receptable is configured to couple to the first plug. The second receptable is configured to couple to the second plug. The coaxial cable is configured to provide (i) a first electrical path for a first electrical current between the first board and the second board, and (ii) a second electrical path for a second electrical current between the first board and the second board.

A vehicular camera includes a front housing portion, a first circuit board having an imager, a second circuit board in board-to-board electrical connection with the first circuit board, and a rear housing portion having a connector for electrically connecting to an electrical connection of a wire harness of a vehicle. The rear housing portion when joined with the front housing portion forms a camera housing. The connector of the rear housing portion includes a multi-pin connector having at least three terminals that, with the rear housing portion joined with the front housing portion, electrically connect to respective terminals of the electrical connector at the second circuit board. The connector includes an electrically conductive metallic clamping element that engages a metallic shield element at the electrical connector at the second circuit board to establish a ground path from the connector of the rear housing portion to the second circuit board.

A connector includes a housing having a bore therein. A center conductor element is positioned in the bore and includes a center conductor pin. The center conductor pin is spring-biased to move longitudinally in the housing bore for being compressed. A ground sleeve element is coaxially arranged around the center conductor element and is also spring-biased to move longitudinally in the housing bore for being compressed. The center conductor element and ground sleeve element are coupled together for moving together in the housing bore when compressed. The compressed elements maintain their same coaxial position in the housing bore with respect to each other when the connector is compressed.

An assembled electrical connector has a base having a terminal stage formed on a top thereof, an upper cap, a first conductive terminal mounted in a center of the terminal stage, and a second conductive terminal externally assembled on the base. The second conductive terminal is a ring sheet, surrounds the terminal stage, and is electrically isolated from the first conductive terminal via the terminal stage. The upper cap is tubular and is connected on the top of the base. The second conductive terminal abuts against an internal surface of the upper cap. Because the second conductive terminal is externally assembled on the terminal stage of the base and is not combined with the base via insert molding, the second conductive terminal does not need to use a machining product.

A bullet-type connector includes an axially compressible housing, a central conductor, and a dielectric mount. The axially compressible housing is compressible in an axial direction at least 2.5% of an overall length of the axially compressible housing. The central conductor defines a first female connecting end and a second female connecting end, the central conductor being positioned within the axially compressible housing. The dielectric mount mounts the central conductor within the axially compressible housing.
