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. These 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 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. If a poor solder joint is formed, such 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 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.
  • WO92/15187 discloses a stiffening element for strengthening the edge region of a bent printed circuit board, and also incidentally engaging a pair of connectors end-to-end.
  • the stiffening element has a longitudinal slot which receives the edge of the circuit board and straightens out any warpage in the edge region of the circuit board so that the connectors may be mounted to the ends of the circuit board.
  • the stiffening element is a separate piece and merely holds the connectors in alignment with the edge of the circuit board.
  • EP-A-661779 which is comprised in the state of the art pursuant to Article 54 (3) and (4) EPC for designated states DE,GB and FR only, describes a connector assembly two connectors held in a parallel side-by-side relationship within a skeleton that provides a base for receiving a common holding member.
  • the surface mount board-to-board connector of the present invention overcomes the above-mentioned disadvantages and 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.
  • 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 1 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.
  • Each receptacle preferably includes an interior pedestal 32 having generally the same height as the sidewalls 22, 24. (FIG. 5.)
  • the pedestal 32 as illustrated, has a generally elongated rectangular, or box-like shape, and is spaced apart from the housing sidewalls 22, 24 and endwalls 26, 28 by a predetermined distance to define an interior channel, or space 36, that surrounds the pedestal 32 of each female housing member 20 and that receive plug portions of counterpart male housing members 60 as explained below.
  • Each female housing member 20 further contains a plurality of electrically conductive terminals 38 disposed therewithin and extending outwardly therefrom.
  • the terminals 38 include contact portions 40 which are disposed along the interior surfaces 33 of the pedestal 32 and tail portions 42 which extend outwardly from the female housing member 20.
  • the terminal tail portions 42 penetrate through bases, or floors 44, of the female housing members 20 and extend outwardly adjacent the bottom surfaces 45 of the female housing members 20 within a recess 46 formed along the bottoms of the housings and extending between the ends 48, 49 of the housings 20.
  • the dual female housing members 20 are interconnected at their opposite ends 48, 49 by spacer, or bridging members 50, which extend for approximately the full width of the housings 20 between the outermost sidewalls 22 thereof.
  • the spacer members 50 are preferably identical in shape with each other and include base portions 52 which abut base portions 53 of their associated housings 20.
  • the two base portions 52, 53 cooperate to define the recesses 46 at the housings 20 which enclose the terminal tail portions 42.
  • the housing base portions 53 preferably include mounting posts 54 which extend downwardly as shown in FIG. 4 and are received in appropriately sized openings (not shown) formed in the circuit board to accurately position the connectors on the circuit board.
  • the spacer members 50 maintain the two female housings 20 in a spaced-apart generally parallel relationship and, as illustrated in FIG. 5, the spacer members 50 preferably have a height less than the pedestals 30 and sidewalls 22, 24 of the two housings 20 so that the pedestals and sidewalls may project above the spacer members 50 in order to facilitate engagement with their respective counterpart male housings.
  • the spacer members 50 and housings 20 may be formed from a conventional dielectric material, such as plastic and preferably a high-temperature material such as liquid crystal polymer (LCP), and may be effectively made by a conventional injection molding process, wherein the housings 20 are molded in place around the terminals 38. As illustrated in the embodiment of FIGS. 1-5, the spacers 50 are integrally formed with the housings 20 so that the resulting female connector assembly 16 constitutes a unitary structure.
  • LCP liquid crystal polymer
  • the endwalls 26, 28 of the receptacles 30 abut the spacer members 50 and may be offset as illustrated in FIG. 2 to provide a polarizing means, shown as notches 56 which receive like protrusions from counterpart male housing members 60 in order to ensure a proper orientation between the circuits of the two circuit boards 12 and 14.
  • the male connector assembly 18 is best illustrated in FIGS. 6-9 and 14 wherein it can be seen that the male connector assembly includes two elongated male housing members 60, having a pair of protruding plugs, shown as elongated wall portions 62, 64 interconnected to a pair of endwalls 67, 68 at opposing ends to define an overall rectangular plug associated with each male housing member.
  • 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 such protruding wall portion 62, 64 of the male housing members defines plugs that are received with the female housing member receptacle channels 34.
  • each such protruding wall portion 62, 64 contains a plurality of spaced-apart cavities 70 formed in the inner surfaces 72 of the projecting walls 62, 64 which receive a like number of electrically conductive terminals 74 therein.
  • the male connector housing terminals 74 include contact portions 75 primarily disposed within the cavities 70, and tail portions 76 which project through the bottoms, or floors 78, of the housings 60 to extends outwardly from the male housing members 60.
  • the male housing member terminals 74 are arranged in a longitudinal spacing which substantially matches that of the female housing member terminals 38 so that pairs of opposing male and female housing member terminals 74, 38 will share common centerlines.
  • the thickness of the protruding walls or plugs is slightly less than the width of the female housing member channels 34 so that the plug terminal contact portions 75 will reliably engage the female housing member terminal contact portions 40 within the receptacle channels 34.
  • the terminals of both the housing members are preferably formed from a highly conductive material, such as a phosphor bronze alloy and may be gold-plated.
  • the terminals are set in the connector housing members by overmolding, that is positioning the terminals within a mold cavity and injecting molten plastic around them.
  • the housing members may include openings 71 in their appropriate sidewalls 62, 64 (FIG. 7) by which the terminals 74 may be held in the mold cavity during manufacture.
  • the male housing members 60 also include spacer, or bridging members 80, located proximate to the endwalls 67, 68 of the housings 60.
  • the spacer members 80 extend for approximately the width of the male connector assembly 18 (FIG. 6) and, as illustrated in FIGS. 7 and 8, cooperate with the ends of the housings 60 to define an elongated recess 82 which extends along the length of the male housing members 60. These recesses accommodate the tail portions 76 of the male housing member terminals 74.
  • the spacer members 80 maintain the male housing members 60 in a generally parallel relationship such that the centerlines of the two male housing members 60 will precisely match the centerlines of their two opposing female housing member counterparts 20.
  • the male housing member plug wall portions 62, 64 will be slightly offset from the female housing member receptacle channels 34. This misalignment is likely to cause damage to the plug wall portions 62, 64 themselves, such as by bending them outwardly or by decreasing contact forces between terminals which results in unreliable interconnections.
  • the spacer members 60, 80 substantially decrease the likelihood of such misalignment from occurring between the male and female connector housing assemblies 16 and 18 because they ensure that each of the male housing assemblies will be parallel and each of hte female housing assemblies will be parallel. Accordingly, rather than requiring the accurate placement of four connectors, only two connectors must be positioned. This reduces the likelihood of misalignment of the assemblies.
  • FIG. 15 illustrates one type of misalignment which may occur using surface mount, board-to-board connector housings, in which two, unconnected female surface mount connector housings 20" are mounted to a first circuit board.
  • the connector housings 20" include central pedestal portions 32" enclosed by sidewalls 22" and 24" which define plug-receiving channels 34". If the counterpart male connector housings 60" are also unconnected, they may be misaligned on the opposing circuit board with respect to the female connector housings 20", and the plug portions 62", 64" thereof will be offset with respect to the female channels 34".
  • the interconnection of the connector housings by the present invention reduces the possibility of this type of misalignment from occurring.
  • the offset may be at an angle ⁇ to a centerline of one of the female connector housings 20" and will result, as shown in phantom, in the plug portions 62", 64" either stressing the sidewalls 22" of the female connector housings 20" by forcing them outwardly, or misaligning or spacing apart opposing pairs of terminals of the two housings.
  • 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.
  • FIG. 16 illustrates an example of another type of misalignment which may occur in surface mount connectors.
  • 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.
  • the present invention substantially avoids this problem by maintaining the solder tails in alignment.
  • FIG. 14 is a cross-sectional view of two male and female connector assemblies 16, 18 interengaged in a manner to provide an electrical connection between the first and second circuit boards 10 and 12.

  • the terminals 38, and especially the contact portions 40, of the female housing members 20 are received within recesses 35 formed on the interior surfaces 33 of the pedestals 32 so that they oppose and contact the contact portions 75 of the male housing member terminals 74 held within the cavities 70 of the protruding wall plugs 62, 64.
  • FIG. 11 illustrates a second embodiment of a surface mount, board-to-board connector 200 constructed in accordance with the principles of the present invention in which a pair of elongated connector housings 202 are interconnected by separate spacer members 204.
  • the connector housings 202 illustrated receive appropriately configured plug portions of male connector housing incorporating similar structure described for the embodiment of FIGS. 1-9, except for the presence of separately formed spacer members 204.
