An electrical connector comprises a first connector half having two rows of first contacts in an insulative housing and a second connector half having two rows of second contacts in an insulative housing. When the second connector half is fitted with the first connector half, the second contacts mate with the first contacts. In addition to these contacts, a plurality of third contacts are provided with a predetermined pitch extending between the first contacts in the first connector half, and a plurality of fourth contacts are provided with the same pitch extending between the second contacts in the second connector half. The fourth contacts are positioned in such a way that when the first connector half and the second connector half are fitted together, the fourth contacts will be offset in the direction of their alignment with respect to the third contacts by a distance of half the pitch. As a result, when both connector halves are fitted together, respective third contacts engage respective fourth contacts positioned on the right and left, one after another, whereby the third contacts and the fourth contacts are connected consecutively in a zigzag pattern in the longitudinal direction of their alignment.

Electrical connector

A electrical connector assembly comprising first and second, intermatable connector members including respective housings with rows of terminals and rows of ground plate portions extending in spaced apart, side by side relation. Ground plate portions of one connector member include resilient contact portions which are staggered so as to be offset on respective opposite lateral side of a center line of the row thereof and retained in respective housing cavities formed in the housing. A row of correspondingly staggered finger-like projections are provided in the other housing and have guiding and other ground plate supporting portions on respective opposite lateral sides thereof facing in opposite lateral directions and receivable in the respective cavities during movement of the connector members into mating engagement both to support the other ground plate portions in electrical engagement with the resilient ground plate portions and to guide the two housings accurately together.

Electrical connector with improved grounding

An electrical connector has an insulating housing from a rear face of which extends a series of contact leg portions for connection to a series of conductive paths of a circuit board by a surface mount technique and a contact aligning member comprising a cover plate extending transversely from an upright wall having a bottom edge formed with a series of grooves at the same pitch as the conductive paths with respective, downwardly opening, divergent contact leg portion receiving mouths. Side walls extending rearwardly from opposite ends of the body have wall guiding surfaces intersected by a stop groove which receives a detent formed on an upright edge of the wall in a snap action when the contact aligning member is inserted downwardly between the side walls so that the respective contact leg portions enter the respective grooves, thereby being located at the same pitch as the conductive paths and in a common circuit board engaging plane.
