Definitions

  • the present invention relates to a method and apparatus for polarizing a female pin conductor receiving connector.
  • Pin conductors have long been used as a means of providing a male terminal which is mateable with a female connector. Most commonly the pin conductors are arranged in a single row or double rows with the conductors staked into a printed circuit board, mounted on a wafer or mounted on a header.
  • the female connector generally includes a housing having an exterior end wall, a pair of opposing parallel exterior side walls extending from opposite edges of the end wall and a plurality of terminal receiving cavities formed between said side walls and the end wall. Each cavity has a pin receiving opening formed in the end wall. A plurality of terminals are mounted in some or all of the cavities. Each terminal has a portion that is mateable with a pin conductor when the pin conductor is received through the corresponding opening.
  • the pin receiving opening would be blocked by one of two methods.
  • the first method is to mould the opening shut when the housing is initially manufactured.
  • the other method is to manufacture a small plug which is inserted into a pin receiving opening after manufacture of the connector housing. Both of these methods have proved to be extremely inefficient and relatively expensive.
  • the first method is undesirable because it requires a mould tool change for each particular female connector housing.
  • the second method overcomes the first method's drawbacks, however, at the cost of producing an additional part.
  • the female connector includes a housing having an exterior end wall, a pair of opposing parallel exterior side walls extending from opposite edges of the end wall, and a plurality of terminal receiving cavities formed between said side walls and the end wall, each cavity having a pin receiving opening formed in the end wall.
  • a plurality of terminals are mounted in some or all of said cavities, each terminal having a portion that is mateable with a pin conductor when it is received through the corresponding opening.
  • the polarizing method comprised the steps of deforming a portion of the housing adjacent a pin receiving opening to define a deformed section whereby the end wall opening is substantially closed by the deformed section to prevent a pin conductor from being received therethrough.
  • the apparatus for performing said method comprises means for holding said connector in a given disposition and punch means having an end engageable with a portion of the housing adjacent a pin receiving opening for deforming and moving said portion whereby the pin receiving opening is substantially closed to prevent a pin conductor from being received therethrough.
  • FIG. 1 shows a female pin conductor receiving connector, generally designated 10.
  • Connector 10 is adapted to electrically connect a plurality of wires 12 with one of a plurality of wafers, generally designated 14a and 14b.
  • Each wafer comprises an insulative base 16 which is mountable on a printed circuit board 18 and has a group of pin conductors 20a and 20b mounted in and extending from the base 16 in a straight line.
  • pin connectors other than wafers can be used in association with connector 10.
  • the female connector 10 has a housing 21 which includes an exterior end wall 22 and two parallel spaced apart exterior side walls 24 and 26 extending from the edges of the end wall 22.
  • a plurality of barrier walls 28 extend between the side walls 24 and 26 to define with the end wall 22 a plurality of terminal receiving cavities 30.
  • Each cavity 30 has a pin receiving opening 32 formed in the end wall 22 as a means of allowing a pin conductor 20 to be received within a particular cavity 30.
  • Each of the cavities is capable of mounting a terminal, generally designated 36 (Fig. 2), therein.
  • Each terminal has as wire connecting portion 38 at one end and a pin mateable portion 40 formed at the other end.
  • the wire connecting portion 38 is seen to be an insulation displacement section that is well known in the art and the pin mateable portion 40 is seen to be a loop-shaped, double cantilevered configuration also well known in the art. It is understood that there are other wire connecting portions 38 and pin mateable portiions 40 known in the art that would serve the same purposes as set forth herein.
  • both wafers 14a and 14b have three pin conductors 20a and 20b respectively. Also, each wafer 14a and 14b has a blank position 42a and 42b, respectively, wherein a pin conductor could have been mounted but was not. Positions 42a and 42b are purposely left blank as a means of polarizing or keying a particular female connector 10 with a particular wafer 14aand 14b.
  • the pin receiving opening 32 corresponding with the blank position 42 is closed to prevent a pin conductor 20 from being received therethrough.
  • this has been accomplished by either moulding the opening shut or inserting a small plug by hand within the opening.
  • a portion of the housing 21 adjacent a desired opening 32 is modified to produce a deformed section 44.
  • the deformed section 44 is a portion of side wall 24 which is pushed toward the opposite side wall 26 so that it at least partially blocks terminal receiving cavity 30.
  • a pin conductor 20 cannot be received through opening 32.
  • female connector 10 will only be mateable with wafer 14a and not wafer 14b.
  • the connector 10 is held in a suitable connector nest 46 as shown in Fig. 3.
  • the nest 46 can be of a type that is disclosed in European Patent Application Serial No. 83305544.5 publication No. 0104874. However, any connector holding means which presents side wall 24 outwardly is acceptable.
  • a punch 48 is provided having an end 50 which is engageable with the housing 21 to produce the defromed section 44.
  • the end 50 of punch 48 has a slanted surface formed thereat having a leading edge in the plane of the inside of end wall 22.
  • the punch 48 has been actuated by suitable means so that the end 50 engages side wall 24 slanting a portion thereof inwardly toward side wall 26 producing deformed section 44.
  • punch 48 has been retracted leaving the side wall permanently deformed and blocking the adjacent opening 32.
  • the punch 48 operates with a cutting action to sever the deformed section 44 from the side wall 24 along the lower edge of the section 44 and at least partially up its vertical sides so that the section 44 is permanently curled or rolled over into the cavity 30.
  • the housing 21 material is chosen from suitable plastically deformable materials having no substantial shape-memory so as to permit the section 44 to be severed and permanently displaced into the cavity 30 in the manner described. Suitable materials are polyester or filled or unfilled nylon.
  • the punch 48' may alternatively be provided with a rounded nose 50' (see Fig. 6) to form a permanently, inwardly extending depression or "bubble" 44' in the side wall 24 to block the adjacent opening 32.
