Definitions

  • the present invention generally relates to multi-row electrical connectors which mate with arrays of pins.
  • More electronic devices are being designed with an increased number of components which are adapted to be mounted on a printed circuit board.
  • space on a printed circuit board is one of the prime design considerations when attempting to lay out the locations of various components thereon.
  • pins One type of component frequently found on printed circuit boards is square wire pins. Some pins have a nominal dimension of .045 inch (1.14 mm) and are adapted to be force fit through punched holes in the printed circuit board. After the pins are inserted into the printed circuit board, they are wave soldered to provide an electrical connection between the pins and the circuitry formed on the board.
  • a disadvantage of using .025 inch (0.64 mm) square wire pins is that the preformed holes must be drilled because of the smaller cross section rather than punched as with the .045 inch (1.14 mm) square wire pins. It is more expensive to drill than to punch holes in a printed circuit board. Also, a .025 inch (0.64 mm) square wire pin cannot carry as much current as a .045 inch (1.14 mm) square wire pin.
  • female connectors of this type include a housing made of insulation material having parallel top and bottom rows of elongated terminal receiving cavities, each cavity having a pin receiving opening in a forward end and a wire receiving opening at the rearward end.
  • the pin receiving openings have the same configuration as the multi-row pin array.
  • a plurality of terminals are provided to be mounted in the cavities. Each terminal has a pin engaging portion at the forward end and a wire engaging portion at the rearward end.
  • a modular connector housing is disclosed in United States Patent No. 4,492,023 which relates to a method and apparatus for fabricating an electrical harness.
  • the type of connector illustrated therein is a plurality of single row connectors which have an integrally formed housing structure.
  • the housings are connected together by means of a selectively removable web or connecting member.
  • the present invention aims to provide a multi-rowelectrical connector for connecting an array of pins to insulated wire conductors which connector can be mass terminated from the same side of the connector.
  • the present invention provides such a multi-row electrical connector comprising a housing made of insulation material having parallel top and bottom rows of elongated terminal receiving cavities, each cavity being generally defined between two-spaced apart side walls, a top wall and a bottom wall, each cavity having a pin receiving opening in a forward end and a wire receiving opening at the rearward end, said pin receiving openings being in the same configuration as said pin array, a plurality of terminals, one mounted in each cavity, and each having a pin engaging portion at the forward end and a wire engaging portion at the rearward end, and characterized in that the wire engaging portion of each terminal includes an insulation displacement slot for receiving an insulated conductor therein, to displace the insulation and electrically contact the conductor, in that the cavities of the top row being staggered with respect to the cavities of the bottom row, in that the side walls of adjacent top row cavities are spaced apart and in that a slot is formed in the top wall of each cavity extending from the wire receiving opening towards the forward end to expose the wire engaging portion of the terminal therein where
  • the present invention further provides a modular connector housing structure for electrical connectors for connecting any given one of different multi-row arrays of pins to insulated wire conductors so that the same product can be adapted for mating with different arrays of pins
  • the modular structure being made of electrically insulating material, each such connector to include a plurality of terminals each having a pin engaging portion at the forward end and a wire engaging portion at the rearward end and an integrally formed housing structure having a plurality of rows of elongated terminal receiving cavities including a top row and a bottom row, each cavity being generally defined between two spaced-apart side walls, a top wall and a bottom wall, each cavity having a pin receiving opening in the forward end and a wire receiving opening in the rearward end, said modular housing structure connector being characterized by a plurality of modules, each module including at least one top row cavity and at least one bottom row cavity, said pin receiving openings of said modules
  • the present invention still further comprehends a method of making a multi-row electrical connector of the present invention including forming the connector housing by selectively removing modules from a modular connector housing structure of the present invention.
  • FIG. 1 two different dual row electrical female connectors, generally designated 10a and lOb, are shown. Each connector 10a and 10b is used for connecting a dual row array, generally designated 12a (the pin array mating with connector 10b cannot be seen) of pins 14 to insulated wire conductbrs 16.
  • the pins 16 are mounted on a printed circuit board 18 through pin holes 20 prepunched therein.
  • a plurality of polarizing holes 22 are also formed in the board for purposes which will be described in greater detail hereinafter.
  • Each connector 10a or 10b (also, generally referred to as 10) includes a housing generally designated 26, integrally molded from insulative dielectric material such as plastics material.
  • the housing 26 has parallel top and bottom rows of elongated terminal receiving cavities 28 and 30, respectively.
  • Each cavity 28 and 30 is adapted to receive a metal terminal generally designated 32, therein.
  • the terminal 32 is seen to generally include a pin engaging portion 34 of conventional design which is adapted to receive one of the pins 14.
  • a wire engaging portion 36 which has a conventional insulation displacement type slot 38 formed therein.
  • the terminal 32 also includes a locking lance 40 struck out from the bottom thereof.
  • the locking lance 40 engages a portion of respective cavity 28 or 30.
  • Each terminal receiving cavity, 28 and 30 is defined between two spaced apart side walls 42 and 44, a top wall 46 and bottom wall 48.
  • Each cavity, 28 and 30, further has a pin receiving opening 50 in the forward end and a wire receiving opening 52 in the rearward end.
  • the pin receiving openings 50 are in the same configuration as the mating pin array, 12a or 12b.
  • each cavity 28 or 30 has a slot 54 formed therein extending from the wire receiving opening 52 toward the forward end.
  • a lead in portion 56 is formed depending from the slot 54..
  • the slot 54 and lead in portion 56 are used to allow a wire conductor 16 to be guided into a cavity 28 and 30 for electrical connection to the wire engaging portion 36 of terminal 32.
  • a locking window 58 is formed in the bottom wall 48 of each cavity 28 and 30.
  • the window 58 cooperates with the terminal locking lance 40 for the purpose of maintaining terminal within its respective cavity.
  • the top row of cavities 28 are staggered with respect to the bottom row of cavities 30.
  • the arrays 12a and 12b allow for the use of .045 inch square wire pins with closer spacing between the respective rows thereof by staggering one row of pins with respect to the other row. As shown in Fig. 1, the staggered pin receiving openings 50 conform with the corresponding array 12a and 12b.
  • Fig. 1 the same manufactured part is used to result in both connectors 10a and lOb. This is accomplished by integrally molding a plurality of modules, generally designated 64 and defined between lines A-A of Fig. 5, connected to one another to form the connector of the present invention.
  • Each module 64 has one top row cavity 28 and one bottom row cavity 30 connected together by means of a web 66.
  • Web 66 is an extension of side wall 44 of the top row cavity and side wall 42 of the bottom row cavity 30.
  • Each module 64 has a peg 68 extending beyond the forward end of the housing 26. Every other module 64 has the peg 68 extending from the top row cavity 28 while the adjacent modules have their pegs extending from the bottom row cavity 30.
  • Pegs 68 are adapted to be received in printed circuit board holes 22 and serve two purposes.
  • the first purpose is to polarize the connector 10 so that the right connector 10a and lOb is mated with the correct pin array 12a and 12b, respectively.
  • the second purpose is to lock or hold the connector 10 onto the printed circuit board 18.
  • a flexible bubble portion 70 is formed on the end of each peg 68 to engage the bottom surface of the printed circuit board 18 when the peg 68 is inserted through hole 22.
  • Adjacent modules 64 are integrally connected to one another by means of selectively removable module connecting members 72 and 74 connecting the top row cavities 28 and bottom row cavities 30, respectively. Connecting members 72 and 74 can be removed by suitable means in order to detach one or more modules 64 from the structure to form a housing 26 of a desired configuration.
  • peg 68 is selectively removable. If peg 68 is not required, it too, can be removed by suitable means.
  • the housing structure disclosed herein By using the housing structure disclosed herein, the efficiencies of manufacturing one product are achieved. Further efficiencies can be enjoyed by virtue of the ability to mass terminate a multi-row connector from the same side.
  • Figs. 1 and 4 to 8 show a module 64 containing two cavities 28 and 30, it is to be understood that practically any sized module containing at least one top row cavity 28 and one bottom row cavity 30 can be designed.
  • Fig. 9 shows modules 84 defined between lines B-B of Fig. 9 each comprising three cavities.
  • Each module 84 has two cavities 28 or 30 of one row connected to one cavity of the other row 28 or 30.
  • the modules 84 are arranged in an alternating flip- flop fashion so that a module 84 comprising one top row cavity 28 and two adjacent bottom row cavities 30 is is adjacent to a module 84 which comprises two top row cavities and one bottom row cavity 30.
  • each module 84 is connected to one another by means of three webs, 86, 88 and 90.
  • Web 86 connects the two adjacent cavities in the same row between their respective side walls 42 and 44 near the forward end thereof.
  • web 86 is an extension of the top walls 46 thereof.
  • web 86 is an extension of the bottom walls 48 thereof.
  • Webs 88 and 90 connect the one cavity of one row with the two adjacent cavities of the other row.
  • webs 88 and 90 extend downwardly as extensions of side walls 42 and 44 to connect with side walls 44 and 42 of different adjacent bottom row cavities 30. If the module 84 has a single cavity on the bottom row, then webs 88 and 90 extend upwardly as extensions of side walls 42 and 44 to connect with side walls 44 and 42 of different adjacent top row cavities 28.
  • the peg 68 extends beyond the forward end of the housing 26 from webs 86. Thus, there is one peg 68 for each module 84.
  • the pegs 68 are adapted to be received in holes 22 formed in the printed circuit board 18 in the manner discussed above.
  • Adjacent modules 84 are integrally connected to one other by means of the top row and bottom row selectively removable module connecting members 72 and 74, respectively.
  • Connecting members 72 and 74 are similar to webs 86 except they do not have the peg 68 formed thereon. The connecting members 72 and 74 may be removed to form the desired connector 10 as described above.
