Definitions

  • the present invention relates generally to electrical connectors and, more particularly, to an improved surface mount, board-to-board connector having an increased number of electrical terminals and a structure which decreases the likelihood of encountering misalignment of the connector terminals during installation to a circuit board.
  • Board-to-board connectors for electrically connecting a pair of parallel circuit board or members are well known in the art. These board-to-board connectors typically utilize two opposing connector components mounted to respective opposing surfaces of the circuit boards and which project away from the circuit board mounting surfaces.
  • One of the connector components is a male member and includes a plug member
  • the other of the two connector components is a female member and includes a receptacle.
  • the male plug member fits into the female receptacle in order to connect the two circuit boards together.
  • Board-to-board connectors further include a series of electrical terminals disposed in the two interengaging male and female connector members which contact each other when the male member is fitted into the female member.
  • terminals have solder tail portions which extend out from the connector member bottom portions and either extend through holes in a circuit board or engage a like number of electrical contact pads, or traces, formed on the surfaces of the respective circuit boards and are subsequently soldered thereto.
  • This latter mounting method is referred to in the art as surface mounting.
  • Surface mount connectors present certain problems which may compromise the reliability of the connection between the connector terminal tails and the circuit board contact pads.
  • the contact terminals of surface mount board-to-board connectors extend along the length of the connectors and thus, the number of circuits that a surface mount connector can accommodate is limited by the length of the connector.
  • a surface mount connector that accommodates a small number of circuits, such as 20 circuits, is much shorter than a connector that must accommodate a large number of circuits, such as 200 circuits or more.
  • circuit boards may be formed according to low tolerances that may lead to warping or other distortion in circuit boards which may occur during the manufacture of the circuit boards, during assembly of components onto the circuit boards or during assembly of secondary circuit boards to a mother board.
  • heat generated by soldering components, or terminals of a connector, to a circuit board may create thermal stresses within the circuit board which induce warpage or distortion into the circuit board.
  • secondary circuit boards when secondary circuit boards are mechanically mounted to a mother board, such as by standoffs, they may be mounted either unevenly or the securement screws overtightened such that internal stresses may develop within the circuit boards which also may induce warpage or distortion into the circuit board.
  • This area of distortion typically manifests itself as a depressed or raised area of the circuit board that is no longer co-planar with the mounting surface of the circuit board.
  • This warpage or distortion may prevent some of the connector terminals from lying adjacent to and -3- in contact with the circuit board contact pads. Rather, some of the connector terminal tails may be spaced apart from the opposing circuit board contact pads by a gap equal to the displacement of the warped area from the board mounting surface. With such a gap, the possibility exists that the terminals may not contact the solder paste or at least not become reliably attached to the circuit board during the soldering. If the solder tail is not soldered to its corresponding contact pad, the entire board will be defective.
  • soldered joint will be weaker than the rest of the soldered joints that occurs between the connector and circuit board in the area that is not warped and may eventually fail.
  • the problems described above may be avoided by utilizing surface mount connectors of relatively short length so that the connector and its associated terminal tails will lie flat on the circuit boards within the area of warpage as opposed to extending across the area of warpage.
  • this solution limits the design of the electronic component to the use of a single, short length connector. In applications where the circuit boards have a large number of circuits which must be connected between two parallel circuit boards, a longer length connector must be used to accommodate this larger number of circuits.
  • the surface mount connector has a length which is greater than the warped area
  • a portion of the connector and its associated terminal tails may extend over the warped area and out of contact with the contact pads thereof.
  • the likelihood of encountering a warped area on a circuit board also increases.
  • the likelihood of moving the terminals out of parallelism also occurs.
  • Misalignment or rotation of one connector relative to the other of only 1 degree may result in an offset of approximately 0.861 mm for the connector which will effectively prevent mating of the connectors on the first and second boards and possibly result in some of the connector terminal tails not contacting their corresponding circuit board contact tails.
  • the present invention overcomes these disadvantages and provides benefits over the prior art by providing two connectors arranged in a generally parallel fashion and joined together by bridging pieces which maintain the two connectors in a generally parallel and side-by-side relationship.
  • Another object of the present invention to provide a new and improved surface mount, board-to-board electrical connector assembly for connecting two parallel circuit boards together, which connector assembly includes two connector housings interconnected by spacer members.
  • Still another object of the present invention is to provide a dual housing board-to-board, surface mount connector assembly having a male connector component and a female connector component, the male connector component having two elongated connector housing bodies interconnected at their opposing ends of the connector bodies to maintain the connector housing bodies in a parallel relationship and to maintain the electrical contact terminals disposed within the connector housing bodies in alignment with the circuit board contact pads.
  • a still further object of the present invention is to provide a board-to-board, surface mount connector assembly having male and female dual interengaging connector housings of relatively short length, wherein the male and female dual connector housings are joined together by bridging pieces at their opposing ends in order to maintain the connector housings in a parallel spacing, thereby improving the interengagement of the male dual connector housings with the female dual connector housings and thereby reducing the likelihood of misalignment of the connector housing during attachment to a printed circuit board.
  • the present invention is directed to a surface mount board-to-board connector which overcomes the above- mentioned disadvantages and which offers an improvement over prior art surface mount, board-to-board connectors by reducing the overall length of surface mount board-to- board connectors while accommodating a larger number of circuits relative to the length of the connector and reducing the likelihood of encountering a warped or distorted mounting area.
  • an improved surface mount, board-to-board connector assembly includes a dual plug housing assembly and a dual receptacle housing assembly.
  • the plug housing assembly has two male connector housings disposed generally parallel to each other and joined together at the opposing ends of the housings by spacer members, or bridging pieces integrally formed with the male connector housings.
  • the receptacle housing assembly has two female connector housings disposed in a spaced-apart, parallel relationship and joined together at opposing ends by integral spacer members which maintain the alignment of both the plug and receptacle housings for mounting purposes and also maintain the alignment of the contact terminal tails.
  • the improved board-to-board connector assembly includes a pair of opposing male and female dual connector assemblies, each of the male and female connector assemblies having two elongated housing portions arranged in a spaced-apart, parallel fashion, with each housing portion having a plurality of electrical terminals disposed therein on opposing surfaces thereof.
  • the electrical terminals of the male and female connector assemblies engage each other when the connector assemblies are interengaged with each housing portions having engagement members disposed on opposing ends received within recesses formed in separate spacer members having engagement means that engage opposing ends of the housings.
  • the spacer members interconnect the housings of the male and female connector assemblies together and maintain them in spaced-apart, parallel fashion, whereby, electrical terminal tails extending from the housing are aligned with each other and with opposing electrical contact traces upon mounting surfaces of opposing printed circuit boards.

  • a surface mount, board-to-board connector assembly constructed in accordance with the principles of the present invention is generally designated at 10 in FIG. 1 and, as illustrated, is shown to interconnect a first circuit board 12 with an opposing, second generally parallel circuit board 14.
  • the connector assembly 10 includes a plurality of electrical terminals, generally indicated at 15, which extend out from two opposing connector component assemblies 16 and 18 and which provide a means for connecting the connector component assemblies 16, 18 to a plurality of corresponding circuit board contact pads, or traces 17, on respective opposing circuit boards 12, 14.
  • One connector component 16 is illustrated as a female connector assembly while the other connector component assembly 18 is illustrated as a male connector assembly. As explained in greater detail below, portions of the male connector assembly 18 are received within portions of the female connector assembly 16 in order to effect a connection between the two connector assemblies.
  • FIG. 10 illustrates a conventional printed circuit board C having a mounting surface S disposed on one side thereof.
  • the mounting surface S typically defines a mounting plane P-P which ideally is coincident with the mounting surface S of the circuit board C.
  • a gap ⁇ occurs between the surface W of the circuit board within the area of warpage and the ideal mounting plane P-P. This gap ⁇ is generally equal to the displacement distance between the bottom surfaces of the solder tails T of the connector and the actual plane of the circuit board which occurs within the warped area, indicated at P'-P'.
  • Gap ⁇ presents a problem that may affect the integrity and reliability of the interconnection between the solder tails T and the circuit board contact pads 17.
  • a solder paste composed of a powdered solder and a flux is typically applied to the circuit board by way of an appropriate masking process to apply the solder paste onto the areas of the circuit board where connections are to be made, thereby forming a solder paste layer of a predetermined thickness.
  • the solder paste is permitted to partially set-up and connectors and other components are applied to the circuit board to form a circuit board assembly.
  • the surface mount connectors are positioned on the circuit board so that their solder tails lie upon the contact traces and the solder paste layer on the contact traces.
  • the circuit board assembly is then passed through an infrared oven, or other appropriate heating means, in order to melt the solder paste and form a connection between the connector solder tails and the circuit board contact pads.
  • Acceptable board warpage is often .007 inches per inch of board.
  • the solder paste layer is typically very thin, ranging from between approximately .006 inches and approximately .008 inches.
  • a thin solder paste is required because the pitch, or center to center spacing Q, (FIG. 2) between adjacent terminals tails of surface mount connectors may be very small, on the order of between approximately 0.635mm to 0.8mm.
  • a thick solder paste layer may therefore increase the likelihood of the solder paste flowing between contact traces and inadvertently bridging two contact traces when subject to a heating process.
  • the gap ⁇ is large enough such that a solder tail does not contact the solder paste, it is unlikely that a connection will be made between that particular terminal solder tail and contact pad pair (T, 17) , rendering that particular circuit defective and the circuit board potentially useless.
  • the gap ⁇ is such that the connector solder tail barely touches the solder paste layer but does not touch the contact trace, the connection formed between the particular solder tail-contact trace may be weak.
  • the likelihood of encountering a warped area is increased when a surface mount connector H ⁇ of relatively long length is used as compared to a connector H 2 of relatively short length.
  • an appropriately sized connector may be able to abut the surface W of the circuit board within the warped area without encountering any gap between the terminal tails and the circuit board contact pads.
  • circuit boards must accommodate more circuits, so it becomes desirable to interconnect more circuits on the opposing boards together.
  • the present invention provides a board-to-board connector assembly in which each connector component 16, 18 accommodates an increased number of electrical circuits without increasing the overall length of the connector and provides a structure in which the co-planarity of the solder tails is maintained and in which the solder tails of the connector assembly are maintained in alignment with the contact pads 17 of the circuit boards to which it is mounted.
  • the female connector assembly 16 of the overall connector 10 of the present invention includes a pair of elongated female housing members 20 having opposing sidewalls 22, 24 and endwalls 26, 28 which cooperate to define an interior opening, or receptacle 30.
  • Each receptacle 30 preferably includes an interior pedestal 32 having generally the same height as the sidewalls 22, 24. (FIG. 5.)

  • the endwalls 67, 68 provide reinforcement to the relatively thin plug walls 62, 64 inasmuch as the mated height between the surface mount connector components 16,18 may range from between approximately 4mm to 7mm and the height of the plug walls 62, 64 will consequently range from less than approximately 4mm to less than 7mm.
  • the endwalls 67, 68 further define a polarizing means, shown as extensions, or studs 69, which are received within the polarizing notches 56 of the female housing members 20 in order to ensure proper engagement between the two connector assemblies 16, 18.

  • Each male housing member 60 may further include an appropriate means for mounting the housing members 60 to a circuit board, illustrated as first and second posts 84, 86. (FIGS. 7-9.) Both posts 84, 86 are received within openings formed in the circuit boards.

  • a connector housing 90 is illustrated as properly positioned on a circuit board 91 within appropriate mounting holes.
  • Superimposed on the connector 90 in phantom is the outline of the same connector, but skewed 1 degree from its centerline which may result from the mounting holes being oversized. This angular displacement has been determined to result in an offset of approximately 0.861 mm.
  • This large offset increase the possibility that the connector terminal solder tails 92 may either be misaligned with respect to their corresponding opposing contact pads 84 of the circuit board or may not effectively contact at least one of the contact pads. As mentioned above, if contact between just one solder tail and contact pad is not made, the circuit is ineffective and so is the connector.
