Description




FIELD OF THE INVENTION




The present invention relates generally to electrical connector devices, and more specifically to connectors for use in high data rate applications.




BACKGROUND OF THE INVENTION




Current “box level” interconnect and cabling technologies utilized by original equipment manufacturer's are driving overall system level enclosures to be smaller while increasing electrical performance of these same devices. Various requirements arise in order to facilitate the increased electrical performance of these devices. For instance, it is more critical to use highly reliable discrete wire termination methods, which are the processes for attaching the end of a line, channel or circuit to an electrical contact. It is desirable to have the option of logic (e.g., a printed circuit board) and discrete wire termination methods inside the same cabling medium. It is common for form factor requirements to drive industry standard design point data rates past intended design points. For example, Very High Density Cable Interconnect (VHDCI) connector devices designed for transmitting 40 MHz data rates actually carrying mission critical data at over 2 GHz. Of course, it is advantageous if interconnecting systems are compatible with legacy and current technologies. All of these requirements require special manufacturing processes combined with small form factor assembly and packaging methodologies. The current available industry solutions limit the ability in solving these issues cost effectively.




An important aspect of technologies for interconnecting electrical cabling involves terminating the cabling at a connector device. Current technologies from terminating cabling include insulation displacement contact (IDC), the use of printed circuit boards, solder termination, and welded or “direct attach” methods. Each of these current technologies have different characteristics, which will now be briefly explained.




IDC involves attaching wires to the electrical interconnects of a connector device by placing an insulated wire between two metal prongs, which also serve as electrical contacts. The two metal prongs cut through the insulating material and at the same time make electrical contact with the conductive wire. The electrical performance of systems utilizing IDC is limited because the skew of each wire is difficult to control. The skew is the amount of misalignment between each wire and the interconnect (or contact lead) to which it is attached. Skew causes inconsistencies in the amount of contact formed between each of the wires and a respective interconnect. The variations in the amount of contact area is a critical problem in high transmission rate applications because it disrupts the timing of the finely synchronized signals in each of the wires. Therefore, IDC is generally a lesser-preferred method for terminating cabling for critical data applications.




Printed circuit boards are used to terminate cabling by connecting PCB's to electrical interconnects and soldering discrete wires to the PCB. In this manner, the PCB's are utilized as an intermediary connecting medium and are sometimes referred to as “interposer cards.” The PCB method introduces the additional discrete wire-to-interconnect termination point, which can cause further reliability and quality problems. The PCB itself also adds the cost of an additional component. PCB's actually provide some ability to improve electrical performance, for example, the embedded wire traces allow for the control of the wire layout at the PCB. However, problems arise in high frequency applications. Also, in general, the data frequency range for PCB connected systems are limited at high end, which is typically around 1 GHz.




Soldered termination involves soldering discrete wires directly to an electrical interconnect. The effectiveness of solder termination of fine pitch contacts in existing designs is limited by the ability of operators or processes to solder with a sufficient amount of precision. This naturally leads to reliability and quality problems. Additionally, material characteristics of the bond between cabling, interconnects and solder limit the performance of systems to data frequency ranges of approximately 1.2 GHz. Furthermore, current design points limit wire management options in small form factors, and electrical issues, such as skew, are virtually unsolvable at high frequencies.




Welded or “direct attach” methods involve welding wires directly to a contact surface. Skew is hard to control in welding methods due to the lack of discrete wire management features and therefore, electrical performance of the electrical system is limited. It is also very difficult to obtain consistent repeatability in welding production. Auto-indexing features of current weld tools tend to limit throughput rates. Typically, connector designs consist of multiple rows within a single housing. This usually causes problems in manufacturing since positive and negative weld plates/heads must be used. Fixturing this type of application in small form factors such as VHDCI is extremely costly.




In view of the foregoing, a low cost interconnection device capable of reliably carrying high data rates would be desirable.




BRIEF SUMMARY OF THE INVENTION




The present invention is directed to a small form factor connector device that can reliably carry high data rates and which can be implemented at a low cost. The disclosed connector device can be adopted across multiple interconnect platforms including current, legacy, or yet to be defined form factors. The device disclosed is modular in its approach, offers multiple termination mediums, and can be used in a variety of electrical packaging applications. The connector device ensures a high degree of wire position control through the use of wire retention combs and/or registration holes. The wire retention combs grip the discrete wires and the registration holes secure the ends of the exposed wires such that a stable and precise connection between the wires and the electrical contact leads of the device can be maintained. Each of these features, alone or in combination, thereby substantially reduces skew between wires and electrical interconnects of a connection device and allows for successful signal transmission at high frequencies. In alternative embodiments of the connector device, one surface of the contact leads are designed to connect with discrete wires and an opposite surface of the contact leads are designed to connect to an electronic device card. In some embodiments of the present invention, the connector device is formed of two substantially identical components that are attached to each other.




One aspect of the present invention relates to an electrical connector component that includes a plurality of contact leads and a registration block. The plurality of contact leads each have a first connection portion and a second connection portion, the first connection portion being suitable for connection to an external electrical system. The registration block has a plurality of registration recesses that are positioned proximate to the second connection portion of an associated contact lead and configured to receive and position an end portion of an associated wire to be connected to the second connection portion of the associated contact lead. In an alternative embodiment of this electrical connector component further includes a wire retention comb supported by the plurality of contact leads and spaced apart from the registration block such that the second connection portion is exposed between the registration block and the wire retention comb. The wire retention comb include a row of teeth wherein at least one adjacent pair of teeth is configured to secure an associated wire that is to be connected to the second connection portion of a selected one of the contact leads.




These and other features and advantages of the present invention will be presented in more detail in the following specification of the invention and the accompanying figures, which illustrate by way of example the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION




The present invention will now be described in detail with reference to a few preferred embodiments thereof as illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known operations have not been described in detail so not to unnecessarily obscure the present invention.




The connector device of the present invention has features that allows for precise connections to electrical wires, the flexibility to connect to both wires and an electrical device card, allows for easier termination to such devices, and has a design amenable to low cost production. The features that allow for such characteristics will now be described with respect to the figures.





FIG. 1

illustrates a perspective view of a connector device


100


according to one embodiment of the present invention. Connector device


100


is designed to connect discrete wires and/or an electrical device card, such as a PCB card, to an electrical system, such as a personal computer, server, etc. Connector device


100


is formed of two substantially similar connector components


102


and


104


that are placed together, thereby giving the connector device


100


a symmetrical shape. In some embodiments, connector components


102


and


104


can be identical in shape and/or size to each other. Each of the connector components


102


and


104


have a wipe area or termination strip


106


, a shroud support ledge


108


, a wire registration block


110


, a discrete wire contact region


112


, and a wire retention comb


114


. Each of the connector components


102


and


104


are formed such that when they are placed together, a device card slot


116


is created. Device card slot


116


is designed to receive and secure an electronic device card, which can be used as a wire termination medium. Specifically, the device card itself, sometimes referred to as an interposer card, will be attached to electrical wires. To guide a device card into device card slot


116


, registration surfaces


118


and


120


are formed on each end of each connector component


102


and


104


, respectively. It should be noted that device card slot


116


can receive various types of connection mediums that are able to fit inside the slot


116


. In alternative embodiments of the present invention, the connector components


102


and


104


do not have to be substantially similar or identical in shape and/or size. For instance, each of the components


102


and


104


can have different shapes to conform to different design requirements.




Within each of the connector components


102


and


104


, electrical contact leads


122


extend from the surface of the wipe area


106


, to the surface of the wire contact region


112


, and finally, to the inside surface of the device card slot


116


. At least a portion of the inside surface of the contact leads


122


are designed to make contact with the electrical traces on a device card that is inserted into the device card slot


116


. The wire contact region


112


on the outside surface of the contact leads


122


are designed to connect with discrete wires. The exposed contact leads


122


on the surface of the wipe areas


106


are designed to make contact with an electrical system when the wipe area


106


is connected with an external connector of the electrical system. The structural region formed by the combined wipe areas


106


of the two connector components


102


and


104


is sometimes referred to as a termination strip. Connector device


100


is thereby able to connect both discrete wires and a device card to an electrical system. The connector device


100


can be used in various ways such that in some embodiments, only discrete wires are attached, in others only a device card is inserted, and sometimes, both discrete wires and a device card can be connected to the connector device


100


.




The fact that the connector device of the present invention is formed from two similar components is advantageous for various reasons. First, forming the connector device


100


from two similar or identical connector components


102


and


104


allows for lower overall production costs since less tooling is required to manufacture components having different configurations. Also, assembling and attaching wires to the connector device becomes simpler since the connector components can be worked with separately. This is especially advantageous given that the connector devices of the present invention are intended to be manufactured to have small form factors. As should be appreciated by those of skill in the art, the connector components that form the connector device are preferably made of a dielectric material. In alternative embodiments of the present invention, the connector device


100


can be formed from a single piece of material, rather than be formed from two separate halves. In other embodiments of the invention, the connector device could have contact leads


122


on only one side of the connector device.




Registration block


110


and wire retention comb


114


are provided to firmly secure the connection of each of the discrete wires to the wire contact regions


112


of respective contact leads


122


. The registration block


110


stretches across the width of the connector device


100


and includes registration holes


124


that are aligned with each of the contact leads


122


. By inserting the end of each discrete wire into a respective registration hole


124


, the end of each wire can be accurately secured, thereby aligning one end of each of the wires with a respective contact lead


122


to which the wire will be connected. Such alignment also tends to align the longitudinal axis of the wires with the longitudinal axis of the wire connection regions


112


of the contact leads


122


. Each of the registration holes


124


preferably have the same depth so that the ends of the wires attached to the wire connection region


112


are aligned along the same axis. The diameter of each registration hole


124


should be sized to securely restrain the ends of each wire above a respective contact lead


122


. The registration holes provide added precision in the termination of discrete wires to contact leads, which is critical in high speed data applications.




The wire retention comb


114


includes a set of teeth that are designed to receive and secure the discrete wires. The width between each teeth of the retention comb


114


is sized so that each pair of teeth can firmly secure a wire to the connector device through frictional forces. Preferably, each pair of teeth will grip onto the insulated portion of a discrete wire. The teeth are positioned such that each wire will be secured directly above the wire connection region


112


of a respective contact lead


122


. The retention comb


114


thereby increases the stability and strength of the electrical connection between the discrete wires and the contact leads


122


in the wire contact region


112


. The registration block


110


and the retention comb


114


work together to strengthen the connection between the discrete wires and the contact leads


122


by securing both ends of each of the wires that will make contact with the wire connection region


112


of the contact leads


122


. The registration block


110


and the retention comb


114


also ensure that the longitudinal axes of both the wires and the wire connection regions


112


of the contact leads align with each other. Additionally, the wire retention comb


114


provides the discrete wires with strain relief, which is the ability of the wires to remain connected to the contact leads


122


despite forces applied to the wires during physical handling of the connector device


100


. The wire retention comb


114


provides added precision in the termination of electrical wires to the contact leads, thereby making the connector device


100


capable for convey data at high rates.




In alternative embodiments of the present invention, the connector device may only incorporate either the registration block


110


or the retention comb


114


, but not both. Such design considerations will depend upon the specific application for which the connector device will be used.




The shroud support ledge


108


provides a surface upon which to attach a shroud in order to cover and protect the exposed contact leads


122


on the surface of the wipe areas


106


.

in greater detail.

FIG. 1. A

contact lead


122


can be seen within the sectioned surface of the connector device


100


to run from the wipe area


106


to the wire contact region


112


and then to the device card contact region


126


. Due to the drawing limitations required for clarity purposes within

FIG. 1A

, the bracket designating device card contact region


126


is position on the outside of connector device


100


even though device contact regions


126


are located on the interior surface of the device card slot


116


. The contact leads


122


have a bending profile that can be more clearly seen in FIG.


2


.




Also, as can be seen in

FIG. 1A

, the top and bottom surfaces of the wire contact regions


112


in each of the connector components


102


and


104


are exposed between the registration block


110


and the wire retention comb


114


. Exposing both the top and bottom surfaces of the wire contact regions


112


is useful when the connector components


102


and


104


are separated from each other. For when the connector components are separated from each other, welding mechanisms can more easily make contact with the contact leads


122


on the two separate surfaces to form the required electrical circuit. The exposure of the wire contact regions


112


makes it possible to mass weld a respective wire onto each of the plurality of contact leads simultaneously.





FIG. 2

illustrates a side plan view of an isolated pair of conductive contact leads


122


(


a


) and


122


(


b


), shown in their relative orientations when connector components


102


and


104


are placed together. Contact lead


122


(


a


) represents a contact lead from connector component


102


and contact lead


122


(


b


) represents a contact lead from connector component


104


. Section A is the portion of the connector leads


122


in the wipe area


106


. The outside portions of the contact leads in section B make contact with discrete wires in the wire connection area


112


, and the inside portions of the contact leads in section C make contact with a device card in the device contact region


126


. Note that the contact surfaces in sections B and C are on opposite surfaces of the contact leads


122


. The contact leads


122


bend inwards at section C to form a leaf spring configuration such that the contact leads


122


(


a


) and


122


(


b


), together, exert a compressive force on an inserted device card. The compressive force provides a more secure connection between the connector device


100


and an inserted device card. In some embodiments, the longitudinal axes of the contact leads


122


in sections A and C are within the same plane. In other embodiments, depending upon the design requirements, the contact leads in section C are closer to each other than the contact leads in section A.




The connector device


100


can have a varying number of contact leads


122


that span the length of each connector component


102


and


104


depending upon the specific data application. In one common embodiment, each of the connector components


102


and


104


have thirty-four (34) contact leads


122


such that connector device has a total of 68 contacts.




The connector device of the present invention is versatile with respect to the various termination methods that can be utilized. As shown above, discrete wires and device cards can be attached to the connector device


100


. Discrete wires can be terminated through soldering or through welding, which creates a direct metallurgic bond. In soldering and welding type terminations, mass or discrete termination of wires is possible since the wire contact regions


112


are not obstructed to machining tools. Mass termination refers to the process of simultaneously connecting multiple wires to respective contact leads. On the other hand, discrete termination refers to connecting wires individually to respective contact leads. To accomplish the various termination methods, the only changes needed are in the plating of the contact leads


122


. For instance, when soldering the discrete wire attachment, tin and lead is used, and when the wires are welded to the contact leads


122


, nickel is used to plate the contact leads


122


. In some applications of the connector device of the present invention, each of the pair of connector components of the connector device


100


could be terminated to discrete wires using different techniques depending upon specific design criteria.




The device card can be attached to the connector device of the present invention via soldering with tin and/or lead.




Embodiments of the connector device can be based on the Very High Density Cable Interconnect (VHDCI) standard, which is applicable to Low Voltage Differential-Small Computer System Interface (LVD-SCSI) applications for both current and legacy interconnect schemes. VHDCI connectors and retention schemes comply with physical interface and performance requirements set forth in Standard Proposal No. 3652-A, issued by the Electronic Industries Association.

, which includes wire connection region

.

FIG. 4

is a view of the inside surface of the connector component


102


, which will make contact with the connector component


104


. As can be seen in

FIG. 4

, the inside surface of the wipe region


106


has locking bars


150


and locking channels


152


. Each of the locking bars


150


and locking channels


152


will fit into locking channels and locking bars, respectively, on a mating connector component. These locking bars and channels help the connector components maintain a relative orientation with respect to each other when attached to each other. Near the locking bars


150


are also formed locking knobs


154


and locking holes


156


, which act similarly to lock mating connector components together. As appreciated by those of skill in the art, the locking bars, channels, knobs and holes can have other various shapes, sizes, and positions on the inside surface of the connector components. These various locking features can be generically referred to as locking pegs and recesses. In some embodiments, the locking pegs and recesses can be shaped so that each peg snaps into and is therefore securely held by a respective recess. Such “snap-fitting” pegs and recesses can be used to secure the connection between a pair of connector components.




As shown in

FIG. 4

, the contact leads


122


are spaced apart from each other such that air spaces


158


, spanning from the wire connection area


112


to the device card connection area


126


, exist between each of the leads


122


. The air spaces


158


increase the electrical performance of the connector device


100


by maximizing the “dielectric constant of air.” Of course, it is understood that the contact leads


122


, in the wire contact region


112


and the device card contact region


126


, could also be embedded in the dielectric material that forms each of the connector components.





FIGS. 5 and 6

will now be presented to illustrate how discrete wires are connected to the connector device


100


.

FIG. 5

illustrates a perspective view of a connector device


100


having discrete wires


170


connected to each of the contact leads


122


in the wire connection area


112


of each of connector components


102


and


104


. Only the portion of the wires


170


leading out from the wire connection area


112


are shown for simplicity's sake.





FIG. 6

illustrates a close-up, perspective view of connector component


102


and a single, attached wire


170


. The insulated portion of the wire


170


is placed between a pair of teeth


172


of the wire retention comb


114


. Each pair of teeth


172


are spaced apart so that they securely grip the insulated wire


170


. By gripping the insulated portion of the wire


170


, the exposed end


171


of the wire


170


can remain in contact with the contact lead


122


regardless of typical external forces exerted on the wires


170


during installation processes. As can be seen, the exposed, conductive end


171


of wire


170


is placed on top of a contact lead


122


to form an electrical connection. In some embodiments of the present invention, the contact leads


122


can be formed to have a recessed trough


174


that runs the length of the contact lead


122


in the wire connection area


112


. The recessed troughs


174


are sized such that the exposed portion of the wire


170


can rest within the troughs


174


and therefore be more securely fixed to the contact leads


122


. The exposed end


171


of wire


170


is inserted into a registration hole


176


formed in the registration block


110


. As can be seen, the registration holes


176


are aligned with each of the contact leads


122


. As mentioned earlier, registration holes


176


are recessed areas that secure the ends of the wires so to keep them aligned for proper contact with the contact leads


122


. In high data rate transmission applications it is important to terminate each of the discrete wires


170


so that they connect to the contact leads


122


through the same amount of contact area or length. Haying the same length is important since the uniformity of contact surface area affects signal propagation. Aligning multiple discrete wires along the registration block


110


and within the registration holes


176


allows the wires to have uniform contact points with the contact leads


122


. As mentioned above, the wire


170


can be fixed to the wire connection region


112


of the contact leads


122


either though soldering or welding.





FIGS. 7 and 8

respectively illustrate connector


100


prior to and after receiving a PCB card


180


according to one embodiment of the present invention. As can be seen in

FIG. 7

, PCB card


180


is inserted with the end having electrical connection points


182


into the device card slot


116


. Once the PCB card


180


is inserted, as seen in

FIG. 8

, electrical connection points


182


make contact with the electrical contact leads


122


in the device card connection region


126


. In some embodiments, the registration surfaces


118


and


120


have an additionally formed hook that is designed to clip onto a notch formed in the PCB card


180


in order to secure the connection between the connector device


100


and the PCB card


180


. Not shown, for clarity sake, are the electrical wires that are connected to the PCB card


180


. For easier manufacturing, the wires can be connected to the PCB card


180


before the PCB card


180


is inserted into the connector device


100


.




Also illustrated in

FIGS. 7 and 8

are two locking clamps


184


and


186


, which are attached to the connection device


100


in such a way as to wrap around the connection device


100


and hold the individual connector components together. The two locking clamps


184


and


186


wrap around the wire contact regions


112


and the wire retention combs


114


of both connector components


102


and


104


. The locking clamps


184


and


186


can have various shapes and sizes such that they can cover more or less area of the connector device


100


. As can be seen in

FIG. 10

, each of clamps


184


and


186


is formed of a flat panel that has clips on either end. The locking clamps


184


and


186


are designed so that their respective panels cover one of the connector components while their respective clips attach to the other connector component. In this manner the locking clamps tend to secure the attachment between the connector components


102


and


104


. In some embodiments, the flat panel surfaces of the locking clamps


184


and


186


also press down on the insulated portions of the discrete wires


170


and thereby provide additional strain relief. It is possible to use only one locking clamp, as opposed to using two at the same time.




Clamps


184


and


186


have are the same shape and size, thereby making the manufacture of these pieces easier. However, in alternative embodiments, clamps


184


and


186


can have different shapes and sizes. In alternative embodiments, no locking clamps are required. For instance, in these embodiments, the connector components


102


and


104


may clip to each other or they may be held together with an adhesive material such as epoxy.





FIG. 9

illustrates a perspective view of a connector device


100


utilized in a hybrid manner in which both discrete wires


170


and a PCB card


180


have been connected to the device
