Definitions
- the present invention relates to electrical connectors and more particularly to electrical connectors which are used for miniaturized, high density and high pin count applications.
- the Brief Description of Prior Developments Recent advances in the design of portable or mobile electronic equipment have required that connector technology keep pace with the trends of miniaturization and functional complexity. Connectors used in such applications need to be more substantially densely packaged than was heretofore generally required.
- Such board to board types of connectors are usually used to interconnect two printed circuit boards in an "mezzanine" configuration. Such uses require connectors not only with smaller contact pitches, but, in some cases, with lower mating heights, as well.
- the resulting increased packaging density must ordinarily be achieved without significant sacrifice of mechanical ruggedness since such connectors may be subjected to unusually high stresses because of the nature of the application. For example, miniaturized or mobile type products are subject to high stresses if they are dropped or otherwise abused. Such high stresses have the potential for damaging connector housings, contacts and solder joints. Furthermore, the connectors themselves might separate if sufficient retention forces are not available.
- the "blade-on-beam" connector design is commonly used for miniaturized designs of .8mm and less. This design typically uses a single cantilever beam type of contact for the spring contact which mates an associated blade contact, which does not have spring characteristics.
- the contact beams generally can be of two configurations.
- One such configuration is an edge stamped or "tuning fork” configuration in which the contact is blanked from flat material and reoriented 90 degrees when it is inserted into the housing so that the blanked edge of the beam is in contact with the blade.
- This design has the advantage that complex configurations which have a high degree of compliance can be easily stamped.
- the cantilever beam geometry can also be optimized by stamping an idealized shape into the profile of the beam. For example, a constant stress beam with a parabolic shaped thickness profile might be readily stamped. This approach might allow for lower contact height and tighter pitch contacts.
- the mounting of the contact in the housing is generally accomplished by individually stitching the contacts into the housings.
- An alternative design makes use of a more conventional approach in which the beam is stamped so that the rolled edge of the material is in contact with the blade.
- the contacts can usually be stamped on the same pitch as the final configuration, and the forms of the contact are created by bending the material during the die stamping operation.
- these beams are usually not quite as mechanically efficient as the edge stamped design, they often are more cost effective since they can be mass inserted or insert molded into the housing thus making assembly either easier or less costly from either a product or machine standpoint. This type of product is also easier to electroplate and the contact surface is usually superior to the edge stamped type of contact.
- contact pitch is from .8 -.5mm
- mating height is from 8mm-3mm
- connector width is from 6-7mm
- the electrical connector of the present invention fills the above stated need and comprises a first element comprising (i) at least one insulative lateral support means, (ii) an insulative medial lateral support means and (iii) a conductive means having a first longitudinal section fixed to the insulative lateral support means, a second longitudinal sectional fixed to the insulative medial support means and an exposed third longitudinal section interposed between said first longitudinal section and said second longitudinal section.
- This connector would also include a second element comprising (i) at least one insulative support means and (ii) a conductive means having a first longitudinal section fixed to the insulative support means and an exposed second longitudinal section which is in contact with the exposed third longitudinal section of the first element.
- a mold is first produced.
- This mold includes a first mold member having a planar section and a medial projection having a medial surface and opposed lateral surfaces.
- the mold also includes a second mold member having a medial section and a pair of inner opposed lateral projections and a pair of outer opposed lateral projections the second member is capable of being superimposed over said first member such that each of said inner opposed lateral projections are positioned adjacent the opposed lateral surfaces of the medial projection of the first member and that each of said outer opposed lateral projections are adjacent the planar section of the first member such that a medial cavity and opposed lateral cavities are forward between said first and second members.
- a pair of opposed conductive members having inner and outer terminal ends are then interposed between said first and second mold members such that the inner terminal ends are in spaced relation in the medial cavity.
- Each of the conductive members is interposed in contacting relation between one of the opposed lateral surfaces of the medial projection of the first member and one of the inner lateral projections of the first member.
- the conductive members pass through one of the lateral cavities and then are interposed in contacting relation between the planar section of the first member and one of the outer lateral projections.
- the lateral cavities of the mold are at least partially filled with a liquid polymeric molding compound and allowing said molding compound to solidify so as to form opposed solid insulative lateral support structures each having one of said conductive elements embedded therein.
- the lateral cavities and the medial cavity are filled with the liquid polymeric molding compound. Strain relief, high speed low cross talk and through mount embodiments are also disclosed.

- the conductive members would also have a second section 90 which would be interposed between the inner projections of the second mold member and the lateral surfaces of the medial projection of the first mold member.
- a third section 92 which would be positioned in one of the lateral cavities 78 or 80.
- a fourth section 90 for the conductive member would be interposed between the outer projection of the second mold member and the planar section of the first mold member.
- Conductive members would also have an exterior exposed section 96 with a strip outer terminal end 98.
- the planar section of the first mold member would have outer opposed bores 100 and 102 which would receive pilot pins 104 and 106. These pilot pins would engage the conductive members adjacent their outer terminal ends.

- This mold would be used to manufacture this particular plug shown in Fig. 3 in the same way as was described above in connection with the mold shown in Fig. 7.
- the method of this invention involves molding the housing around the contacts as an approach to manufacturing this class of products, rather than molding thermoplastic housing and subsequently inserting or stitching contacts into the housings.
- the contacts are stamped on continuous strip at the pitch of the final application.
- contacts for a .5mm pitch connector will be stamped on .5mm.
- the nature of the stamping operation allows for very tight tolerance control of this process since the pitch of the stamping can be held to within tenths of thousandths of an inch.
- Secondary stamping operations might be used to perform bends in the stamped strip, but in any case the contact strip is then placed into the mold and plastic material is molded around the contacts, preserving their spatial relationship to one another. The contact carrier strip can be then removed, and the pitch is preserved by the housing.
- This procedure is an improvement over stitching contacts into a housing, where the relationship of the contacts to each other is entirely determined by the pre-molded housing. Since the contacts are completely embedded in the thermoplastic material, the base of the cantilever beam is uniformly and securely held in the plastic matrix. This procedure allows for heavier wall thicknesses and more uniform stress distribution as compared to a stitched or mass inserted part, when the contact beam is deflected during use. This secure contact will lessen the potential for stress relaxation of the contact because of permanent deformation of the plastic material and will result in higher contact forces over the life of the product, as compared to alternative manufacturing methods. Preferably, both contacts of the connector, particularly the cantilever beam contact half (receptacle), should be molded simultaneously for a number of reasons.
- the structural integrity of a single piece design would be better in a one piece design as compared to multiple pieces, and the tolerances or variability of a one piece design would be less.
- molding two rows of contacts in this configuration is not a simple matter. It is difficult design mold tooling that will seal the plastic around the contact areas (the "seal-off tooling) without complex camming of the mold or fragile easy to damage tooling. This must also be done without compromising the structural integrity of the part. There are several methods by which this can be accomplished.
- the mold should be a straight draw mold with no or limited camming actions in mold.
- the "seal-off area at the interface between the plastic housing and the contact should be a flat area preferably with an interface angle of less than 45 degrees.
- the contact beams were molded at less than 45 degrees and then bent into position by means of a pin or blade that could be inserted through an aperture in the bottom of the connector.
- a second, and probably a preferred case would be to design the housing so that tooling can be placed on the outside of the connector contact, from the bottom of the connector and from the top.
- the plug portion of the connector is similarly molded as a one-piece unit. Again, in this case two contact strips are placed into a mold and with appropriate coring, the contacts are secure in a plastic matrix. In this case the contact portion is molded at a slight taper so that proper "seal-off can be maintained.
- the coring provides an area underneath the contact area of the plug which is devoid of plastic material, and the contact beams are supported by a bar of plastic material which embeds the ends of the contacts. This bar is attached intermittently and at the ends to the base of the plug.
- One advantage of this approach is that it minimizes the potential for a flash of plastic material to flow into the contact area. It also eliminates plastic material between the contacts, which can result in improved electrical crosstalk performance between the contacts and between rows of contacts.
- the insert molding of the contacts into the housing can allow for shorter contact beams, since less plastic material can be used to secure the contact. Because, tolerances can be held more tightly, a shorter contact beam can be used, since less compliance is required to accommodate the mating.
- the particular receptacle configuration shown, with the open bottom can be used to further advantage, since the nose of the plug can extend almost to the printed circuit board surface, thereby increasing the contact "wipe" characteristics of the connector.
- solder tails are insert molded in place. That is, they are formed prior to molding rather than after it.
- precise nature of the mold tooling helps to define the co-planarity of the contacts, rather than bending on plastic material, which can be a source of considerable variation.
- the bottom surface of the connector is flat providing a barrier to flux and other contaminants to the contact area, as compared to conventional designs in which there openings underneath the connector to accommodate the lead thickness and bend radius.
- board-to-board, mezzanine style connector system where connectors are required to be applied in tandem. This might be required to accommodate pin counts beyond the design capability of an individual connector or process, or to give stability to an otherwise unstable board-to-board structure.
- the biggest problem in accomplishing this is to easily make sure that the dimensional variation between the two connectors does not exceed the mating tolerances allowed between them.
- One obvious method is to carefully fixture the two connectors with external tooling that assures the correct relationship between the two connectors. This can be readily accomplished in limited production circumstances where cost is not a major problem, but could prove difficult and expensive in high volume applications, where multiple fixtures would have to be built and maintained.
- Another approach has been to mold the two connectors together with a connecting bar or bars, this would be adequate in very high volume applications which could justify this type of tooling approach, but it could have limited use in relatively low volume application or in cases where the connector spacing could change.
- the permanent bars could also interfere with other devices on either side of the board assembly when they are plugged together.
- Another approach to this problem would be to have an external molded interconnecting bar, that could serve as a disposable fixture.
- This bar could preferably be mounted to the top of the connector housing with latching features or by simple friction fit to the connector contacts.
- the cap thereby formed over the connector contacts could be utilized as a pickup cap for robotic placement and as protection against contact contamination.
- the cap/ fixture could be removed after soldering and recycled.
- the connector includes a plug shown generally at numeral 310.
- the plug is comprised of elongated lateral supports 316 and 318 and a medial support 320. There is an open space 321 between the lateral supports and above the medial support in the plug.
- the plug also includes a plurality of opposed blade elements (not shown) similar to the blade elements shown in Fig. 3. Similar to the blade elements in Fig. 3, each of these blades includes a first section which is partially embedded in one of the lateral supports and a second section which is embedded in a medial support and interposed between these first and second sections there is an exposed third section. Exposed solder tail as at 332 and 333 also extend outwardly from the second section.
- the connector also includes a receptacle shown generally at numeral 334.
- This receptacle includes an elongated opening 336 which receives the elongated medial support 320 of the plug.
- this receptacle includes elongated insulative lateral supports 340 and 342 which are positioned in opposed parallel relation. Between these lateral supports there is an open space 343.
- a plurality of parallel conductive beams as at 344 and 346 extend in opposed relation from each of these lateral supports. Similar to the arrangement shown in Fig. 6 each of these beams has a first section which is embedded in one of the lateral supports and a second exposed section which extends upwardly and inwardly to contact one of the blade elements of the plug.
- Solder tail as at 351 and 353 also extend from the receptacle.
- the connector includes a plug shown generally at numeral 410.
- the plug is comprised of elongated lateral supports 416 and 418 and a parallel medial support 420. There are open spaces as at 421 between the lateral supports and above the medial support in the plug.
- the plug also includes a plurality of opposed blade elements shown generally at numerals 422 and 424. Each of these blades includes a first section 426 which is partially embedded in one of the lateral supports and a second section 428 which is embedded in a medial support. Interposed between these first and second sections there is an exposed third section 430. An exposed solder tail 432 also extends outwardly from the plug.
- the connector also includes a receptacle shown generally at numeral 434.
- This receptacle includes elongated openings 436 which receives the medial support 420 of the plug. It will also be seen that this receptacle includes elongated insulative lateral supports 440 and 442 which are positioned in opposed parallel relation. Between these lateral supports there is an open space 443.
- a plurality of parallel conductive beams as at 444 and 446 extend in opposed relation from each of these lateral supports. Each of these beams has a first section 448 which is embedded in one of the lateral supports and a second exposed section 450 which extends upwardly and inwardly to contact one of the blade elements of the plug.
- a solder tail 451 also extends from the first section 448.
- the plug 410 has an open internal cavity 453.
- This cavity is produced by the contact support tooling used during the insert molding process.
- a metal or metallized plastic structure 455 is inserted into the cavity 453 of the plug 410 to provide a ground plane underneath the contact arrays on both sides of the plug connector. It is contoured and shaped to accommodate the changes in internal geometry so that a reasonably constant characteristic impedance is maintained throughout the length of the connector cross section.
- the tip 457 of the grounding structure projects through the plug, and when mated to a standard .5mm receptacle, it will form a "choke joint" 459 with the appropriate ground pad on the printed circuit board 461.
- this arrangement can control the overall characteristic impedance of the connector and provide internal shielding so that the electrical characteristics of the connector might be improved.
- the small size of the connector coupled with the impedance control and shielding results in a low cross talk induced by the connector when high speed signals are transmitted through it. As compared to conventional high performance connector systems this performance increase will be possible with a significant decrease in manufacturing costs, as a result of simplified processes and reduced part counts.
- a standard receptacle can be used in the system, further reducing costs.
- the entire connector system may be described as having only three discrete pieces as compared to substantially more pieces in a number of conventional connections. Furthermore, the number interfaces for the ground plane is reduced from three to two, with improved electrical characteristics.
- This embodiment combines the advanced manufacturing methodology insert molding of both contacts simultaneously, with a simplified method for impedance control and cross talk reduction to provide a product of ultimately small size, low profile, high density and superior electrical performance.
- the connector includes a plug shown generally at numeral 510.
- the plug is comprised of elongated lateral supports 516 and 518 and a parallel medial support 520. There is an open space 521 between the lateral supports and above the medial support in the plug.
- the plug also includes a plurality of opposed blade elements shown generally at numerals 522 and 524. Each of these blades includes a first section 526 which is partially embedded in one of the lateral supports and a second section 528 which is embedded in a medial support. Interposed between these first and second sections there is an exposed third section 530. An exposed fourth section 532 also extends downwardly from the second section to allow through mounting on a printed wiring board. There is a cavity 533 in the medial support 520.
- This mold includes a first mold member 552 which is made up of a planar section 554 which has a medial projection 556. There is also a second mold member 564 which has a planar section 566 from which inner opposed lateral projections 568 and 570 depend. Outwardly spaced from these inner opposed lateral projections are outer opposed lateral projections 572 and 574. The second mold member may be superimposed over the mold member so as to form a medial cavity 576 above the medial projection 556. Lateral cavities 578 and 580 would also be formed between the inner and outer projections of the second mold member and the planar section of the first mold member.
- conductive members 584 and 585 which extend respectively into cavities 586 and 587 in mold member 552.
- Each of these conductor members has a first inner terminal end 588 which would be positioned in the medial cavity 576.
- the conductive members would also have a second section 590 which would be interposed between the inner projections of the second mold member and the lateral surfaces of the medial projection of the first mold member.
- a fourth section 590 for the conductive member would be interposed between the outer projection of the second mold member and the planar section of the first mold member.
- Conductive members would also have an exterior exposed section 596 with a strip outer terminal end 598.
- the planar section of the first mold member would have outer opposed bores 600 and 602 which would receive pilot pins 604 and 606.
- This mold would be used to manufacture this particular plug shown in Fig. 14 in the same way as was described above in connection with the mold shown in Fig. 7 except for the differences described below.
- a pre-formed frame of terminal carrier 608 is placed relative to the pilot pins 604 and 606 in the lower mold member 552. Special grooves 610 and 612 in center mold projection when in contact with the terminal carrier strip, create a point of seal-off 614.
- the mold is closed, at which the bottom surface of the upper mold member 564 comes in contact with the terminal carrier 608, creating a situation where the terminal carrier becomes an integral part of the mold seal off structure.
- the terminal carrier strip will be removed later by breaking it away from the bottom of the connector housing and off of each individual terminal tail at a predetermined break away point at terminal end 588.
