A tuning mechanism for tuning a resonant circuit is provided. The tuning mechanism comprises a spring pin having a superconductive, dielectric or magnetic tuning tip attached thereto. The spring pin is slidably inserted into a filter package wall through a mating hole. A mechanism is provided for adjusting the position of the tip within the electromagnetic field above the filter element. The tip may be shaped, thus allowing adjustment of both the height of the tip above the filter element and the position of the tip in a plane parallel to the plane of the filter. Optionally, the spring pin may include an offset to allow close spacing of the tips along with wider spacing of the actuator end of the pin.

An apparatus for connecting a high density cable assembly having a shield and to be connected to corresponding contact pins provided on a substrate having a grounding grid formed of conductive guides, each having a predetermined number of contact pins therein, including a connector to which the cable assembly is connected and which is to be mounted to the associated guide. The connector has a connector body, a connector cover surrounding the connector body, and a latching device provided between the connector cover and the connector body for easily latching and unlatching the connector to and from the associated guides.

A pin grip array zero insertion force connector has 10,000 or more normally closed contacts provided in rows on a motherboard. Alternating rows of contacts respectively include first and second type contacts, and drawbars are provided between the rows of contacts. Alternate drawbars are caused to slide in opposite directions, thereby engaging the drawbars with one of the two tines of each contact in the rows of contacts on either side of the drawbar. An actuator mechanism is provided at each end of the rows of contacts and drawbars to engage and slide the drawbars. To reduce the force necessary to operate each actuator mechanism, the actuator mechanisms may be divided into subactuator mechanisms which are individually actuated. The drawbars comprises a drawbar support strip which engages the actuator mechanisms and an interposer body molded to retaining tabs on the drawbar support strip.
