Abstract: Proposed is a connector assembly for electrically coupling a shielded cable to a ground plane. The assembly includes a metal shroud with pins for press-fitting to the ground plane, and a plug with a shield connection clamped or taped to the cable shield. Ground connections are provided by two paths: one from the drain wire of the cable through a signal contact in the plug and the other through the shield connection and shroud. Spacers in the shroud provide a keying function while permitting end-to-end stacking of plugs. Latching features on the plug and shroud hold the plugs in position and prevent insertion of the plug in the wrong orientation. Heat stakes in the plug can be used for the latching feature.

Abstract: An electrical connector comprises a housing having latch members at both ends of the housing and a pair of metal fasteners capable of clamping on the latch members. The housing has a longitudinal groove for receiving a daughter board. The metal fastener includes a fixing section and a spring section which substantially extends uprightly therefrom. The fixing section clamps on the housing. The spring section is provided with a restriction leg and a slot which are formed by punching, and the restriction leg is substantially vertical to the surface of the spring section. When the metal fastener clamps on the housing, a rib provided at the end portion of the latch member fits the slot of the spring section so as to prevent the side shifting of the metal fastener.

Abstract: A connector system is provided with connectors, each of which comprises at least one shielded terminal. The shielded terminal has a ground contact and at least one signal terminal. The ground contact is substantially identical for signal conductors terminating either in a female, a male, or a hermaphroditic structure. The shielded terminal also has at least one lug extending beyond the shielded terminal. The signal terminal is either provided, at one end of the shielded terminal with at least one clamping lug which can be folded around the signal conductor of an electrical cable to establish a firm electrically conductive contact therewith, or it is integrally made with the signal conductor.

Abstract: An electrical connector assembly according to the current invention comprises a receptacle and a right angle header for connecting two or more printed circuit boards. A composite action beam is located in the receptacle and has a movable end and a fixed end. During an initial phase of the pin insertion cycle, the movable end of the composite action beam deflects so as to minimize the force necessary to insert the pin into the connector housing. During an intermediate phase of the insertion cycle, the movable end contacts an inside wall of the connector and the composite action beam functions as a two-end supported beam. The composite action beam supported at both ends exerts sufficiently high normal force against the inserted pin so as to retain the pin in the inserted position. Thus, the composite action beam reduces insertion force without compromising normal retention force once the pin is inserted.

The connector assembly is an assembly of the connector wafer and the vertical receptacle.

The fins are also curved more inwardly by their fin ends starting from the pointed part over an appreciable part of the longitudinal distance. The curvature of the fin ends first gradually increasing starting at the pointed part, and then decreasing.
