An electrical connector is adapted for use on a substantially planar surface. The connector comprises two arrays of electrical contacts coupled to the planar surface. One array is disposed directly above the other. Each contact in the lower array is mounted directly to the planar surface, with the mounting points arranged in a substantially straight line along the surface. The upper array of contacts is coupled to the planar surface by way of one or more mounting tabs fixed to the surface. The tabs elevate the upper array in relation to the planar surface and the first array. The mounting tabs are fixed to the planar surface along the same substantially straight line on which the first array is mounted. Thus, the mounting points for both arrays of contacts are disposed along the planar surface in a substantially co-liner relationship. The connector further comprises a housing that is fixed to the planar surface and engages the contacts.

The disclosed accessory RF shield has unitized conductive and insulating barrier sheets, sized to correspond lengthwise to the axial length of a ribbon cable to be shielded and widthwise between opposite side edges to completely encircle the ribbon cable and present overlapped inner and outer side edge layers adapted to be connected together for forming a field connection. The disclosed improved field connection has specific preformed structures, including: (1) that the barrier sheets have a lengthwise prefold therein effective to accurately size the inner side edge layer and allow it during field installation to be positioned accurately over the ribbon cable, whereupon further the outer side edge layer may also then be accurately formed when folded around the ribbon cable; (2) a preformed lengthwise narrow bulged side edge conductive band on the inner side edge layer; (3) a preformed lengthwise narrow bulged side edge insulating band on the outer side edge layer; and (4) a lengthwise strip of adhesive on the outer side edge layer inwardly adjacent the strip of adhesive. When the adhesive strip is pressed against the insulating sheet of the inner side edge layer inwardly adjacent the conductive band, the conductive sheet of the outer side edge layer bows over and contacts the bulged conductive band to define an encircling electrical containment around the ribbon cable, and the insulating band on the inner side edge layer is biased against the insulating sheet on the inner side edge layer to define an encircling insulating containment around the ribbon cable.

An upper and lower contact especially for a double-deck or dual in-line module, each includes a solder tail that is coupled to the main body of the contact by a compliant portion. The compliant portion is thus intermediate the main body and the solder portion of the solder tail. The compliant portion isolates and absorbs stresses induced on the module housing through card insertion such that the solder joint does not receive the stress. Additionally, the provision of a compliant portion absorbs non-linearities created by circuit board warpage on which the module is attached. The compliant portion may take the form of a modified spring, a U-shaped section, a radiused section, or other form.

Apparatus for relieving stress between an electrical connector component and the plurality of individual wires terminating at the connector component. The apparatus includes two identical interlocking stress relief elements, each of which releasably engages the connector component. The elements gather the wires together into a group or bundle and allow a wire tie to be applied around the elements and the gathered wires.

A preferred embodiment of an electrical connector system for electrically connecting an electrical device and a substrate includes a header connector. The header connector has a contact. The contact includes a pin for engaging the electrical device; an intermediate portion electrically coupled to the pin for engaging a contact of a receptacle connector mounted on the substrate so that the header connector can be mounted on the substrate by way of the receptacle connector; and a tail electrically coupled to the intermediate portion for engaging the substrate so that the header connector can be mounted directly on the substrate.

A pair of mating connectors includes a receptacle having an insulative housing and at least one conductive receptacle contact with a pair of spaced walls forming a plug contact receiving space. The plug connector has an insulative housing and at least one conductive contact having a pair of spaced walls which converge to form a projection engageable in the plug receiving space of the receptacle contact. In each case, the spaced walls are joined by a bridging structure that unites the walls. The plug and receptacle contacts are retained in the respective housings by engagement of opposed lateral edge portions of the contacts with the housings in a manner to enhance heat dissipation by convection by maintaining substantial portions of the contacts spaced from the housing walls and from each other. The bridging structure may include a retention element for engaging respective connector housings to retain the contact in the housings. The open structure of both the receptacle and plug contacts enhances heat dissipation and allows flexibility in achieving desired contact normal forces.

The open structure of both the receptacle and plug contacts enhances heat dissipation and allows flexibility in achieving desired contact normal forces. The contact construction is especially useful for electronic power connectors. The electronic power connectors can also be modified to accommodate connections for an external AC power supply. The connector housing incorporating the AC power connection capability can accommodate different forms of AC power supply termination contacts, such as spade-type contacts having a spring-like plug for receiving discrete quick connect socket terminals or contacts for connection to bus bars.
