The four corners of the pressure section (20) of the contact (10) punched out of a metal sheet are rounded off to form an oval surface (22). The lower portion (38) of the contact mounting opening (32) of the housing (30) is made of the same configuration as the pressure section (20). Since the dimensions of cross section of the lower portion (38) are made smaller than the corresponding dimensions of the pressure section (20), a tight joining is formed around the pressure section (20).

Electrical connectors

An electrical connector assembly (10,30) includes a metal sheet (20,42), which is in electrical contact with a metal shell (14,32), is embedded in an internal partition (18,40) of a housing (24,44) separating rows of contacts (16,38) for reducing electrical cross-talk between the contacts (16,38).

Shielded electrical connector

The shielded electrical connector (10) has an insulating housing (20), a metal shell (30) and a pair of fasteners (40). The metal shell (30) has resilient fastening legs (33). The fastener (40) has a main leg (41) with resilient arms (42) at its end, which is inserted and retained in the opening (26) of the insulating housing (20). The auxiliary leg (45) is made at a right angle relative to the main leg and has a latching protrusion (46) on its outer surface which becomes engaged with the resilient fastening leg (33) of the metal shell (30). The resilient arms (42) of the fastener (40) are inserted into a through-hole of the printed circuit board, thus achieving the attachment of the electrical connector (10) to the board, while the connection to the grounding layer is performed by means of soldering.

Shielded electrical connector and mounting fixture therefor

A high density electrical connector includes an insulating housing having contacts arranged in rows to engage the contacts of a mating connector, or first printed circuit board, with the contacts having ends extending in freestanding relationship relative to the housing and including a guide member having beveled surfaces to guide the free ends of the contacts into alignment with holes of a second printed circuit board to facilitate mounting of the connector housing and contacts on the second printed circuit board. Embodiments include a guide member which divide at least one row of contacts into two rows and a guide member which guide four rows of contacts into rows of holes in the printed circuit board. The invention contemplates particularly right angle connectors having contacts wherein the freestanding ends are on slightly different centers.
