One-piece molded insulating housing for a circular din connector

A surface mounted shielded electrical connector, comprising;

• a one-piece, molded, substantially rectangular cross-section insulating housing having at one end a mating face and a terminal receiving face opposite thereto, a top wall and side walls, a plurality of elongate terminal receiving cavities each opening into both of said faces, a bottom mounting face for mounting the housing on a surface of a substrate, extending transversely of said mating face and said terminal receiving face, a terminal leg spacer plate projecting from said terminal receiving face in a direction away from said mating face and parallel with said mounting face, elongate, terminal leg retaining notches each extending normally of said terminal receiving face, opening into an edge of said spacer plate remote therefrom;
• a one-piece metal shield enclosing said top and side walls having a front wall with an opening allowing access to said mating face, a plurality of spring fingers extending from the periphery of said opening inwardly thereof to resiliently engage the shield of a mating connector inserted through said opening;
• and
• an electrical terminal received in each cavity having an elongate mating part with a mating end proximate to said mating face and a rear end remote therefrom, an intermediate retention plate retaining the terminal in the cavity, and being connected to said rear end of the mating part, and a terminal leg connected to the retention plate by way of a cranked planar arm and extending parallel to said terminal receiving face and through a respective one of said notches, beyond said mounting face, retaining means on said terminal leg serving to retain it in said respective notch, and wherein one end of said cranked arm is connected to a rear end of said retention plate, the other end of said cranked arm being connected to said terminal leg, said cranked arm projecting from said mating face normally thereof and in substantial alignment with said mating part.

A surface mounted electrical connector, comprising:

• a one-piece, molded, substantially rectangular cross-section insulating housing having at one end a mating face and a terminal receiving face opposite thereto, a top wall and side walls, a plurality of elongate terminal receiving cavities each opening into both of said faces, a bottom mounting face for mounting the housing on a surface of a substrate, extending transversely of said mating face and said terminal receiving face, a terminal leg spacer plate projecting from said terminal receiving face in a direction away from said mating face and parallel with said mounting face, elongate, terminal leg retaining notches each extending normally of said terminal receiving face, opening into an edge of said spacer plate remove therefrom,
• the cavities being arranged in rows displaced from each other in a direction perpendicular to said mounting face;
• and
• an electrical terminal received in each cavity, at least one of said terminals having an elongate mating part with a mating end proximate to said mating face and a rear end remote therefrom, a retention plate connected at one end to the rear end of the mating part and being connected at an opposite end to one end of an arm which is cranked towards one of the side walls of the housing, a terminal leg connected to the other end of said cranked arm, extending therefrom and through a respective one of said notches, whereby at least one of said notches is offset toward a side wall from the respective terminal receiving cavity and the cranked arm makes the transition between the mating part and the terminal leg.

A one-piece dielectric housing for an electrical connector, comprising:

• an elongate circular cross-section plug portion having at one end thereof a mating face, a plurality of terminal receiving cavities extending axially through said plug portion, each cavity having a pin receiving mouth opening onto said mating face;
• a substantially rectangular cross-section connector body formed integrally with the other end of the plug portion and from which projects forwardly a hood surrounding said plug portion in spaced relationship therewith, said hood adapted to allow a circular cross-section electrical socket to be mated with said plug portion, said body defining side walls and having a terminal receiving face opposite to said mating face, each of said cavities extending through said body and having a terminal receiving mouth opening onto said terminal receiving face;
• and
• a terminal leg spacer plate extending from one edge of said terminal receiving face away from said plug portion, said terminal leg spacer plate having a plurality of elongate terminal leg receiving channels extending normally of said terminal receiving face and opening onto an edge of said spacer plate remote from said terminal receiving face, said housing adapted to receive terminals with each terminal having a mating portion received in a terminal receiving cavity and a terminal leg received in a corresponding channel, at least one of the channels offset toward a side wall from the corresponding terminal receiving cavity.
