Definitions

  • a contact for use on printed circuit boards. or the like, or in establishing connections to at least one printed circuit board includes a female contact assembly housing with an internal cavity. Top side and bottom holes are provided in the housing communicating with an internal cavity in which a contact member is located. Contact member includes a straight portion outwardly extending through one of the holes, and a curved portion within the cavity. Thus. when a male contact rod is inserted through one of the holes into the cavity. it contacts the curved portion of the contact within the cavity to establish an electrical conduction path thereto.
  • the female assemblies are provided with an outstanding post with an enlarged portion adjacent its end from one side, and a hole of dimensions similar to that of the outstanding post and enlarged end to receive a similar post from an adjacent identical female connector assembly.
  • the female assemblies can be fabricated in an alignment of the desired number. to form a female connector block of desired dimension.
  • the male rods or posts are mounted in a header which can include, if desired. a clip which engages a shoulder of the female unit to thereby lock the male and female assemblies in connected relationship.
  • This invention relates to electrical connectors. more particularly to improvements in electrical connectors which can be used in number to receive male receiving rods from a header or the like.
  • a female connector is located on the printed circuit board, and the male connector provided separately for insertion thereinto, although, dpending upon the particular application, the male portion may be attached to the printed circuit board.
  • the female portion of the plug or connector are formed of plastic, nylon, or other electrical insulating material with a number of holes aligned along the direction thereof, and with an electrically conducting female contactor located within each of the holes.
  • these are formed in long strips; including, for example, fifteen, twenty, or more holes and connectors.
  • the desired number of connectors are sawed or cut from the connector strip, and applied to the printed circuit board in the desired location.
  • the printed circuit boards frequently have precise areas for definite locations, frequently, in fact, holes, for receiving the connector.
  • the particular tolerances of the connector to be applied, therefor, in its cut dimension must be particularly controlled to enable it to be fitted at the desired location.
  • the connectors typically used are of very precise construction; that is, the spacing and alignment of the individual holes and connectors are within a specified standard, such as, plus or minus twothousandths of an inch. This preciseness, although facilitating uniformity, additionally dictates or requires that the male contactor portion which is inserted into the precisely constructed female portion also be of particular critical spacing between the male contactor members, and in the alignment of the members.
  • hole size itself in the past, has been very critical, for example plus or minus twothousandths of an inch in many commerical applica tions.
  • the particular connectors, of the prior art typically are designed for a particular connection application.
  • the connector to be used is of a particular configuration which will accept a male plug member from a single direction with respect to the board, for instance, from the top, side, or bottom.
  • a top connection connector must be selected.
  • a side or bottom connector must be selected for use.
  • a connector which can be employed to receive a corresponding connector from any direction, which has relatively low insertion and extraction forces to facilitate its mounting or use upon printed circuit boards, and in which the hole side, spacing, and other dimensions need not be of particularly critical tolerance, and which can be formed of single unit building blocks for fabricating a connector of desired size.
  • a connector assembly having a plurality of housings, with each housing having two major surfaces oppositely positioned in two parallel planes, and with a recesed chamber or cavity formed in said first major surface.
  • This recessed cavity takes the form of a closed channel with the inner walls being defined by a tubular element which extends from the bottom of said recessed cavity towards said first major surface.
  • the outer walls of the recessed cavity are essentially straight and form a generally square cross-sectional configuration in a plane parallel to said parallel planes.
  • a rod-like or stub-like element protrudes from the second major surface of the housing and is constructed to snap into the tubular element of another similar housing element.
  • At least two holes extend through the sidewall of the housing and into said recessed channel, with said post-like portion of said contact extending through one of said holes.
  • the second major surface of said other housing covers the first major surface of said first major surface of said first housing to retain said contact in the recessed channel of said second housing.
  • the stub-like protuberance has an enlarged or bulbous shaped and, and the inside portion of said mating tubular portion has an internal bulge or enlarged portion, into which the enlarged end of said stub-like portion will snap-fit.
