Resonance between outer conductors is prevented. A connector includes: a plurality of shield terminals each having an inner conductor surrounded by an outer conductor; and a resonance restriction member that restricts resonance between the shield terminals by connecting the outer conductors to each other and holding the outer conductors at the same potential. Resonance between the shield terminals can be prevented by preventing a potential difference from being generated between the outer conductors.

A low passive intermodulation (PIM) coaxial-to-printed circuit board (PCB) interface and method of constructing the same. According to one aspect, a coaxial-to-PCB interface couples signals between an electrical conductor trace in the PCB and an inner conductor of a coaxial structure having an insulator surrounded by an outer conductor. A metallic cylinder is inserted over the outer conductor of the coaxial structure and positioning the coaxial structure with respect to the PCB so that the outer conductor and insulator of the coaxial structure lie below a lower surface of the PCB. The inner conductor of the coaxial structure is inserted into a via extending from the lower surface of the PCB to an upper surface of the PCB. Solder is deposited in the via to provide an electrically conductive path between the electrical conductor trace of the PCB and the inner conductor of the coaxial structure.

A connector assembly includes housing for storing components of the connector assembly. The connector assembly further includes a cable including a cable center conductor, wherein the cable center conductor is configured as a signal conductor. The connector assembly also includes a first dielectric and an alignment dielectric. Each of the first dielectric and the alignment dielectric includes a path to guide the cable center conductor through an angle to a printed circuit board as the cable is axially inserted into the housing.

A cable television apparatus with a screwless clamping connector structure includes a support structure and at least one rotary connector structure which includes a screwless clamping connection part and a printed circuit board connection part, wherein the screwless clamping connection part includes a first end part which defines an opening to receive a coaxial cable core of a coaxial cable. The at least one rotary connector structure can be rotated to change an opening direction of the opening.

To prevent both increase in impedance and a short circuit, a connector cable is configured such that a connector and a shielded cable are connected via a relay substrate. The shielded cable includes at least an inner conductor, a dielectric covering the inner conductor, and a shield member covering the dielectric. The inner conductor is connected to a contact of the connector at a part where the shield member and the dielectric are removed to expose the inner conductor. At least directly under a part where the shield member is removed to expose the dielectric, a ground (GND) conductor layer on a front surface of the relay substrate is arranged. The GND conductor layer on the front surface of the relay substrate, which is arranged directly under the part where the shield member is removed, is covered with an insulating member.

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 soldering aid for securing a stranded core of a cable on an electrical contact surface of a printed circuit board includes an outer part having a receptacle and a bearing surface, and an inner part that is displaceably received inside the receptacle of the outer part. The inner part has an access opening through which the contact surface is accessible and can be fastened to the outer part in an assembly position. In an inserted position of the inner part in the outer part, an insertion opening in the inner part is aligned with an insertion opening in the outer part for inserting the stranded core of the cable.
