A jack housing () for a plug and jack connector system () comprises a plurality of integrated cable retention hooks () about which to wrap a cable () of a cabled accessory (). The integrated retention hooks () retain the cable () so as to avoid inadvertent disconnect of the plug () from the jack (). The integrated retention hooks () can accommodate a variety of different diameter cables or multiple cables.

A method of manufacturing is employed to produce a size-reduced frequency control device (300), according to the present invention. A temperature compensation circuit (304) and an unsealed piezoelectric element (302) are disposed on a substrate (306) such that the compensation circuit and the unsealed piezoelectric element are electrically connected. A hermetic seal (318) is established between a lid (308) and the substrate such that the unsealed piezoelectric element and at least a temperature sensitive portion of the temperature compensation circuit occupy a sealed environment (320). In this manner, dimensions (322, 324) of the frequency control device are reduced.

A piezoelectric component-mounting foil and foil making method are disclosed, whereby a first portion of the foil in a first plane substantially parallel to a second portion of the foil in a second plane are connected by a central portion not in the first or second plane, the central portion having at least one width dimension of the central portion less than at least one length dimension of the central portion. A conductive foil material, appropriate thickness, overall geometry, and, if desired, appropriate notch configuration are selected for a desired implementation of the foil for conductively attaching and at least partially supporting at least one piezoelectric component such as a quartz crystal.

A shielding apparatus for use with a non-conductive package has an insulated lid (102) which is retained in contact with a substrate (104) for holding an electrical circuit. The shielding apparatus includes a first conductive flash (201) deposited on the interior surface of the insulated lid (102), to produce a substantially contiguous conduction layer, and a second conductive flash (203) deposited over a film (110) disposed on the edge of the insulated lid (102), to produce a partially contiguous conduction layer. The shielding apparatus also includes a layer (108) for affixing the insulated lid (102) to the substrate (104), to produce an enclosure for isolating the electrical circuit from extraneous radio frequency (RF) energy.

A surface mountable piezoelectric device that includes an in situ finish plate mask is mounted on a substrate (20) that includes feedthrough holes (26, 28, and 30) to conduct signals from a piezoelectric element (40) that may include multiple resonator stages (48, 46, 50, and 56). A metallic support structure that includes windows or holes therethrough (72, 74 and 76) permits tuning of the piezoelectric device by mass loading during manufacturing, compliantly supports the piezoelectric element (40), provides RF shielding for the resonators, and is an in situ finish plate mask.
