Header assembly for printed circuit board

A header assembly for a printed circuit substrate comprising:

• a header housing having a generally rectangularly central through opening, a side opening adjacent one end thereof which extends normal to an communicates with the central opening and mounting means for mounting the header housing to the circuit board,
• a pin terminal and carrier subassembly comprising a plastic, generally rectangularly shaped carrier strip having a plurality of openings extending therethrough and a plurality of pin terminals inserted through the openings in the carrier strip and retained in the carrier strip so that their forward and rearward end portions extend outwardly from the carrier strip,
• said header housing adjacent said one end thereof having spaced rails extending along its elongated sides and inwardly into the central opening and said carrier strip having oppositely facing grooves along its elongated sides for receiving said rails on said header housing,
• said preassembled pin terminal and carrier strip being connected to said header housing by sliding said carrier strip through said side opening into the header housing so that said rails are received within said grooves and until said carrier strip engages said header housing at its other end remote from said side opening so that said pin terminals are positioned within said central opening of said header housing,
• a connector subassembly comprising a connector body having a plurality of axially extending cavities therethrough and a plurality of metal socket terminals disposed within said cavities and which receive the forward ends of said pin terminals when the connector subassembly is inserted into the central opening in said header housing and connected to the latter.

• a preassembled pin terminal and carrier subassembly comprising a plastic, generally rectangularly shaped carrier strip having a plurality of openings extending therethrough and a plurality of pin terminals inserted through the openings in the carrier strip and retained in the carrier strip so that their forward and rearward end portions extend outwardly from the carrier strips,
• said header housing and said carrier strip having cooperably engageable means for connecting said preassembled pin terminal and carrier strip assembly to the header housing to position said pin terminals within said central opening in said header housing,
• a connector subassembly comprising a retainer housing, a connector housing having a plurality of axially extending cavities therethrough and a plurality of metal socket terminals disposed within said cavities of the connector body,
• said cavities intermediate their ends being defined in part by split outer wall portions on said connector body, said wall portions being radially flexible and having radially inwardly extending nibs and axially extending tabs located outwardly thereof, said terminals having axially spaced, radially extending, forward and rearward lands defining a recess therebetween, said socket terminals being connected to said connector body by inserting the socket terminals into said cavities and with the forward lands engaging said nibs and deflecting said wall portions and tabs radially outwardly until the forward lands clear the nibs whereupon said wall positions return to their normal position and lock the terminals in place,
• said retainer housing having an outer wall defining a central opening for slidably receiving the connector body therein and having a plurality of axially extending slots in its outer wall for slidably receiving said tabs on said wall portions of said connector body when the latter is connected thereto, said tabs on said wall portions of said connector body engaging said retainer housing and preventing said connector body from being connected to the retainer housing if any of the terminals are not properly locked in place by the nibs on said wall portions,
• first cooperable means on said retainer housing and said connector body for latching said connector body to said retainer housing,
• said retainer housing housing being slidably connected to said header housing by inserting the outer wall of the retainer housing into the central opening of said header housing from its end remote from said pin terminal and carrier strip and with the socket terminals of the connector body slidably engaging the pin terminals carried by the carrier strip,
• and second cooperable means on said header housing and said retainer housing for latching said connector subassembly to said header housing.
