## Background
This application claims the benefit of U.S. provisional application No. 61/728,375, filed Nov. 20, 2012, which is incorporated herein by reference in its entirety.


BACKGROUND
Field
The present disclosure relates generally to electrical connectors and, more particularly, to a interconnect system and universal pull-through receiver for enhancing the organizational and interchangeable electrical engagement between a test adapter and automated testing equipment.
Related Art
Mass interconnect systems and devices enhance connectivity and allow for the reduction, or even elimination, of conventional wiring harnesses when testing complex electrical and electromechanical systems. Typically, mass interconnect systems bring many electrical contacts into contact with each other simultaneously to facilitate efficient connection and disconnection of the testing equipment. For instance, mass interconnect systems and devices may eliminate capacitances, signal crosstalk or other attenuational concerns presented by traditional cable-based systems and devices. Further, mass interconnect systems provide higher degrees of stability, which provide for improved system performance and up-time.
Mass interconnect systems often require the placement of interchange test adapters, or similar wiring modules with multiple electrical contacts in operative engagement with opposing co-acting contact of receiver modules. Typically, the receiver contacts and the interchangeable test adapter align with precision, for instance to minimize, or eliminate, wear and/or equipment damage.
Often the mass interconnect systems connect a testing unit to automated testing equipment. For instance, a mass interconnect system may provide electrical connection for a PCI eXtensions for Instrumentations (PXI)-based test system. PXI systems are intended to measure and automate high-performance applications. Typically, PXI systems incorporate standards governed by the PXI Systems Alliance, all of which are hereby incorporated by reference. For instance, PXI may integrate timing and synchronization to rout synchronization clocks and be reprogrammed to match test, measurement and automation demands.
Traditional cable-based automatic test equipment systems and devices often require system calibrations, which take significant time to remove and carry the risk of performance problems once reinstalled. Mass interconnect systems also help lower the cost of integrating and wiring the systems.
Therefore, Applicants desire a mass interconnect system and universal receiver system adapted to interconnect at least one of a variety of instrumentation platforms without the drawbacks presented by the traditional systems and methods.

DESCRIPTION OF EMBODIMENTS
In the following description, like reference characters designate like or corresponding parts throughout the several views. Also in the following description, it is to be understood that such terms as “forward,” “rearward,” “left,” “right,” “upwardly,” “downwardly,” and the like are words of convenience and are not to be construed as limiting terms.
Referring now to the drawings in general and FIG. 11 in particular, it will be understood that the illustrations are for the purpose of describing embodiments of the disclosure and are not intended to limit the disclosure or any inventions thereto. As best seen in FIG. 11, the universal receiver 46 includes an upper tier 20 with a vertical instrumentation platform 200 and a lower tier 22 with a horizontal instrumentation platform 202. The vertical instrumentation platform 200 secures a vertical interconnect module 214 in a variety of configurations, with the pull-through body 210 extending beyond the universal receiver 46. For instance, as shown in FIG. 11, two vertical interconnect modules 214 are pulled through the upper tier's 20 vertical instrumentation platform 200 and are secured on the opposing rails 258a, 258b. Similarly, the horizontal instrumentation platform 202 secures a horizontal interconnect module 212 in a variety of configurations, with the pull-through body 210 extending beyond the universal receiver 46. Typically, the universal receiver 46 mechanically engages with interchangeable test adapter 12 (shown in FIG. 1) for testing of a piece of automated test equipment. Examples of testing platforms include one, and two or more, of PXI-based platforms, LXI-based platforms, and AXIe-based platforms.
FIGS. 1 and 3, illustrate a mass interconnect assembly having a flexible receiver assembly 10 and interchangeable test adapter 12 according to embodiments of the present inventions. Flexible receiver assembly 10 may include a receiver 46, a carrier building block assembly 14 and interchangeable connector modules 16, 112 and 114. Typically, the interchangeable connector modules are integrated into the flexible receiver assembly 10 from the rear face of the receiver to reduce, or even eliminate, integration concerns associated with feeding the modules through the front face of the system.
As shown in FIGS. 1 and 3, receiver 46 is configured to provide the sprocket side of the interface with interchangeable test adapter 12 of the general type shown and described in U.S. Pat. No. 4,329,005, U.S. Pat. No. 7,016,199 and U.S. patent application Ser. No. 13/586,249, the contents of which are both incorporated herein by reference. However, it is within the sprit of this disclosure for receiver 46 to be configured in a variety of interchangeable arrangements for mounting to a variety of particular pieces of test equipment. FIG. 1 shows flexible receiver assembly 10 properly aligning the connections of receiver 46 to the connections in the interchangeable test adapter 12 to complete the electrical connection between the mating pin/socket contacts. Generally, interchangeable test adapter 12 is the plug to receiver's 46 sprocket and contains mirroring connection with receiver 46.
Typically, receiver 46 has at least two pairs of opposing outer sides that form a generally rectangular, or square, receiver frame. As depicted in FIGS. 1 and 3, receiver 46 is adapted to be mounted and mated with interchangeable test adapter 12 in a substantially vertical manner, however other embodiments include a modular receiver 46 and such receiver 46 may be positioned in a variety of orientations with respect to the interchangeable test adapter 12. For example, other embodiments may include non-rectangular geometrical receivers, for instance to mate with a variety of interchangeable test adapters, including non-rectangular interchangeable test adapters.
In particular embodiments, receiver assembly 10 includes multiple tiers in receiver 46 to house connection modules between interchangeable test adapter 12 and a piece of automated test equipment, for instance a PXI platform, an LXI platform, and/or an AXIe platform-based instrument. The multiple tiers may be openings that are framed by horizontal and vertical support members. Typically, the receiver assembly's 10 horizontal and vertical support members include outer wall members which define the outer periphery of the receiver to mate with ITA and which support inner rail assemblies. For instance, as illustrated in FIGS. 1 and 3, examples of outer wall members in a two-tiered system include a bottom wall 24, a top wall 30 and a middle wall 26 there between. Therefore, the receiver 46 in these examples have two openings: a lower tier opening 22 and an upper tier opening 20. The spacing of the middle wall 26 between the bottom wall 24 and top wall 30 will vary based upon the dimensions of the various connector modules and interconnects, as discussed herein.
As shown in FIGS. 1 and 3, bottom wall 24 and middle wall 26 define lower tier opening 22, which is generally an elongated, rectangular-shaped orifice. Typically, lower tier opening 22 may be sized to receive a variety of receiver assembly 1 elements, for instance interconnect components and/or adjacent carrier building block assembly 14, as an integral unit to be utilized in a variety of configurations. Similarly, middle wall 26 and top wall 30 define upper tier opening 20. While two openings, 22 and 20, are depicted in FIGS. 1 and 2, other embodiments including other arrangements having other numbers of openings, for instance a unitary opening and/or additional rows of openings as discussed later.
FIGS. 1 and 3 further introduce the inner rails along the wall support members to engage the interconnect components and building block assemblies. In some examples, the inner rails may function as an orientation alignment for interchangeably positioning the interconnect components and building block assemblies in a variety of testing configurations and arrangements, while being aligned to mate with their corresponding connections as described herein. As shown in FIGS. 1 and 3, the rail assembly in a two-tier system may include a lower rail 56, an upper rail 58 and an intermediate rail 60 there between. The spacing of the intermediate rail 60 between the lower rail 56 and upper rail 58 will vary depending upon the various connector modules and interconnects discussed herein.
Receiver 46 may have a sliding hanger assembly including a hanger structure and a hanger slide retainer, so that receiver 46 will be flush with the facing surfaces of interchangeable test adapter 12. In some examples, mounted inwardly adjacent to the sliding hanger assembly are left and right slide plates 36. The pair of slide plates may be mounted in any conventional manner so as to slide upwardly and downwardly with respect to the coordinate system of the figures. The motion of the slide plates may be coincident and simultaneous, and for instance, driven by a user. In particular examples, a user may actuate a handle 42. As illustrated in FIGS. 1, 3 and 9, handle 42 may be mounted to one side of receiver 46 and pivot about an axis defined by one end of a torsion shaft, for instance a shaft that runs about the length of receiver 46, for instance as later illustrated in FIG. 8. In some examples, handle 42 may connect two drive linkages, for instance one on each of the left and right sides of receiver 46, as also shown later in FIG. 8.
As shown in FIGS. 1 and 3, each of slide plates 36 may include one or more cam slots 34. Other embodiments include a variety of cam slots 34, for instance to correspond to the number of roller pins 44 positioned on interchangeable test adapter 12 with which receiver 46 is designed to engage. Typically, cam slots 34 are sized to accommodate the interchangeable test adapter 12 roller pins, for instance during upward movement of the slide plates 36. In some examples, cam slots 34 engage roller pins 44 to cause the interchangeable test adapter 12 to move inwardly, for example into engagement with receiver 46. Typically, the electrical contacts carried by the interchangeable test adapter 12 are thereby brought into engagement with the corresponding electrical contacts carried on receiver 46. Similarly, downward movement of slide plates 35 may trigger interchangeable test adapter 12 to move outwardly to disengage electrical contacts carried by the interchangeable test adapter 12 with electrical contacts carried by receiver 46.
Turning to FIG. 8, a modular linkage assembly 160 may enhance engagement of the receiver 46 with the ITA 12. The modular linkage assembly includes a torsion shaft 164 between opposing vertical sides 162 of receiver 46. As shown, a pair of opposing drive linkages 170, 172 on either the left, right or both sides of the receiver may connect the handle 42 and drive movement of the torsion shaft 164. Bearings 166, for instance needle bearings or the like, may be positioned at friction points along the modular linkage assembly to reduce, or even eliminate, galling or seizing. In these examples, the bearings 166 improve the life of the system, as well as provide significant improved feel for the operator when engaging, disengaging the receiver and ITA.
Returning to FIGS. 1 and 3, the lower tier opening 22 may house a variety of interconnect devices that mate with corresponding connections on the ITA. In one embodiment, as illustrated in FIGS. 1 and 2, a substantially permanent adjacent carrier building blocks 14 may mount different types of contacts, for example, contacts that carry electrical power or electrical signals, or contacts of different construction. Adjacent carrier building blocks 14 may define an integral system that is sized to accept and retain a plurality of connector modules to engage electrical contacts carried by the interchangeable test adapter 12 and receiver assembly 10, as described below.
As shown in FIG. 1, adjacent carrier building blocks 14 may include a lower rail 56 and an upper rail 58 that define a chassis side 50. Typically, the chassis side 50 may electrically engage connections in communications with testing equipment, for instance to a PXI. On the opposing side of the building block assembly is a mating side 52 to electrically engage the interchangeable test adapter 12. In some examples, this arrangement is in a substantially fixed position. For instance, adjacent carrier building blocks 14 may be securely positioned within lower tier opening 22 in a substantially fixed position to allow modularity of electrical contacts corresponding to a variety of electrical contacts of interchangeable test adapter 12. Further, carrier building blocks 14 may include adapter openings 54 that are sized in a substantially fixed position, so as to secure adjacent connect modules 16 in a variety of configurations.
In yet other embodiments, as illustrated in FIGS. 3 and 4, the receiver 46 may include an interchangeable infrastructure to support a variety of connector module arrangements to mate with their corresponding connections as described herein. For instance, as shown in FIG. 3, the rail assembly allows convenient integration and interchange of interconnect modules 112 and 114, for example from the rear face of the assembly, to mate with ITA modules 116 and 120. Typically, the upper tier includes a rail system between the bottom wall and the middle wall, wherein interconnect modules 112 may be secured from the rear face of the receiver and mate with the corresponding ITA module. Similarly, in a two-tier system as shown, the upper tier may include a rail system within the boundary of the top wall and middle wall to secure interconnect modules 114 to mate with the corresponding ITA module. Again, the interconnect modules 114 may be integrated in the system from the rear face to minimize, or eliminate, the concerns associated with feeding the system through the testing assembly and/or to reducing tooling and integration expertise.
The adjacent connector modules 16 and interconnect modules 112 and 114 may house a variety of electrical contacts and typically include a wiring side 70 and a mating side 72. Connector modules 16 and interconnect modules 112 and 114 may be made from a variety of materials depending on the desired electrical characteristics. For instance, connector modules 16 may be comprised of NEMA Grade Epoxy Glass G-10 to provide enhanced electrical isolation values.
Further, as shown in FIGS. 1 and 3, adjacent connector modules 16 and interconnect modules 112 and 114 may include a wiring face 70 to carry either a digital or an analog signal. In some examples, the frequency range may be DC up to about forty gigahertz. Further, the current can be up to about fifty amps. In other embodiments, a thermocouple, vacuum and/or pneumatic may be included to complete the connection with connector modules 16. However, as shown in FIGS. 1 and 3, adjacent connector modules 16 and interconnect modules 112 and 114 are typically sized to include electrical contacts to mate with the ITA modules and/or engage the electrical contacts carried by a test fixture interconnect 80.
FIG. 2 shows a perspective view of one embodiment of a receiver assembly 10 introduced in FIG. 1, with upper tier 100 and lower tier 102 in an assembled position. As illustrated, lower tier 102 may include connector modules 16 providing high and low density I/O connectors embedded in adjacent carrier building blocks 14 within the lower tier opening. From a rear perspective of this embodiment, the connector modules 16 may support a variety of electrical connection configurations. For instance, a plurality of connector modules 16 may include split line connectors to indicate at least two connectors on wiring side 70. Other embodiments include a variety of connector and connector module 16 configurations as discussed below.
In one example of the assembled position, the mating side of connector modules 16 is positioned between adjacent carrier building blocks 14, for example in a specific configuration to match a particular piece of testing equipment. A filler plate 94 may be included to block and protect elements of receiver assembly 10, for instance unused connections in connector modules 16. In such a mass interconnect system embodiment a PXI instrument may be attached to a receiver connector module, for instance through a direct access kit (DAK) adapter. The DAK adapter may provide direct connectivity between the PXI instrument and the receiver connector module. Typically, the instruments may be installed and/or removed though the front face of the receiver connector module. Unlike this DAK assembly, traditional cable-based ATE systems and devices often require system calibrations that take significant time to remove and carry the risk of performance problems once reinstalled.
As shown in the partially assembled position in FIG. 2, one embodiment of receiver assembly 10 connects with a test fixture interconnect 80 on the wiring side 70 of connector modules 16. Test fixture interconnect 80 may include several thousand connections in a single engagement with connector module 16. In particular examples, test fixture interconnect 80 may include Flex connectors, PC boards and pre-configured patch cords.
FIG. 4 shows another embodiment of a receiver assembly 10 introduced in FIG. 3, with an upper tier and lower tier in an assembled position. As illustrated, the lower tier may include at least one interchangeable connection module 112 integrated on the receiver 46 and mated with a corresponding ITA connection adapter module 116. Again, the connection module may provide high density I/O connections. As shown, the receiver assembly provides contact pins to incorporate small connectors with both large interchange assemblies and other smaller mass interconnect systems, thus reducing spares, inventory, tooling demands, and other wire cramping, etc. concerns. In particular examples, the ITA connection adapter module 116 may include a printed circuit board assembly 122 or the like for improved user connections as discussed hereinafter. Further, as shown in FIG. 4, the upper tier may include at least one upper interchangeable connection module 114 to generally mate with a corresponding ITA connection adapter module 120. While FIGS. 3 and 4 illustrate only one connection module on the upper and lower tiers, the inventions herein provide convenient infrastructure for a variety of connection module arrangements to meet a variety of mass interconnect demands.
FIG. 5 shows an isolated view of one embodiment of an ITA connection module introduced in FIGS. 3 and 4. Typically, the ITA connection adapter module 116 includes a body to support an engagement lip to mate with an upper or lower interchangeable connection module 112,114, as well as housing for contact points 130. As shown, the upper and/or lower ends of the body may include apertures to receive fasteners to secure the ITA connection module with the opposing connection element. Further, as illustrated, location tabs 134 on the back side of the body allow the user to easily plug the element into place with fasteners through apertures 132, or similar securing procedure recognized by those skilled in the art.
FIG. 6 shows an isolated view of one example of the ITA connection adapter module with a printed circuit board assembly 122 introduced in FIGS. 3 and 4. Typically, a signal element body 150 may be secured to the connection adapter module 116 and generally support the printed circuitry board assembly. As shown, particular examples of the printed circuit board assembly 122 may include HDMI, or similar connections 140. For instance, the printed circuit board may allow connection of HDMI, Ethernet, DMI, USB, seta signal transmission technology and the like, to interplay with the mass interconnect assembly. Such an arrangement significantly improves the interaction of the devices and minimizes the time for integration without the demands and concerns of traditional wiring systems. For instance, standard off-the-shelf cable products may be quickly and easily utilized in the connection 140, thereby minimizing the integration demands and/or skill level required for testing set-up.
FIG. 7 shows another embodiment of connection adapter module 116 having a low insertion force connection 180 that may be used in any of the flexible receiver assembly inventions described herein. For instance, a LIF connector may provide pin and socket connections, for instance for a more rugged connection alternative. Further, LIF embodiments may be advantageous where service requires frequent connects/disconnects. Some examples of LIF include 96, 156 and 260 contact configuration. Typically, LIF connectors are mounted by rotating the mechanism, for example about one hundred and eighty degrees, to engage the LIF mating half. The connector may include a LIF plug 184 affixed to the ITA connector adapter modules 116. A shell 182 may enclose the connections with only the LIF plug protruding through the shell 182. FIG. 7 illustrates a partial shell to show internal components. Further, the shell 182 may be hinged 188, or the like, and include fasteners, for instance attachment 186 as shown in FIG. 7 and the like as recognized by those skilled in the art.
Other embodiments of LIF include a polarizing LIF to provide a unique identity to each connector. A variety of embodiments of LIF plug connectors may be incorporated into the mass interconnect assembly. For instance, a 156 position LIF plug may be used for discrete wiring. Further, hybrid LIF plug with 15 signal positions for instance 16 coax/power, may be incorporated into the system. Still further, a hybrid LIF plug with 72 signal positions for instance 18 coax/power may be incorporated into the system.
A variety of LIF sockets may be used in any of the inventions herein. For instance, a PCB socket may provide enhanced interconnection for rugged system for discrete wiring. Additionally, hybrid sockets that provide a 96 position LIF socket for discrete wiring; hybrid LIF socket for 16 signal positions, for instance having 16 coax/power; and/or hybrid LIF socket with 72 signal positions, for instance having 18 coax/power may be incorporated by any of the inventions shown and described herein.
In yet other examples, receiver coax elements may be incorporated into the inventions described herein. For instance, a 152 position coax module; a 59 position coax module; a 9 position hi-frequency coax module, for instance a 9 position module for SMA; a 12 position hi-frequency, 40 gigahertz module; an 18 position hi-frequency coax module rated for about 50/75 ohms; a 24 position mini-coax module; a 6 position triax module; and/or a 32 position coax module rated for about 50/75 ohms may be incorporated by any of the inventions shown and described herein.

Additional embodiments incorporating AXIe-based platform instrumentation includes any of the technologies and industry standards governed by the AXIe consortium and AXIe-based instrumentation as understood by those skilled in the art having the benefit of this disclosure.
The interconnect modules include a connecting face 204 which is generally positioned on the front of the universal receiver 46 and has a pull-through body 210 extending beyond, including behind, the universal receiver 46, i.e. the front face of the receiver. Therefore, Applicants have unexpectedly discovered the organizational and interchangeable advantages of having vertical and horizontal modules in close proximity to one another to provide platforms for PXI, LXI, and/or AXIe instrumentation platforms for improved electrical engagement between a test adapter and automated testing equipment. As shown in FIG. 11, two vertical interconnect modules 214 are pulled through the upper tier's 20 vertical instrumentation platform 200 and are secured on the opposing rails 258a, 258b. Fasteners 206 may protrude through the connecting face 204 of the vertical interconnect modules 214 and be retained in the fastener apertures in the opposing rails 258a, 258b. Therefore, the vertical instrumentation platform 200 is configured to support a variety of mass interconnect devices, including direct access kits (DAKs), as described and shown herein for PXI, LXI, and/or AXIe instrumentation platforms. For instance, the DAK may include a mating face, i.e. a connecting lip on the connecting face 204, that is generally removably secured to the opposing rails 258a, 258b, while allowing the DAK to be pulled through the receiver 46 having the pull-through body extending beyond the universal assembly of the receiver 46.
As also shown in FIG. 11, a plurality of horizontal interconnect modules 212 are pulled through the lower tier's 22 vertical instrumentation platform 202 and secured on the opposing rails 260a, 260b. Fasteners 206 may protrude through the connecting face 204 of the horizontal interconnect modules 214 and be retained in the fastener apertures in both sets of the opposing rails 260a, 260b. Therefore, the horizontal instrumentation platform 202 is configured to support a variety of mass interconnect devices, including DAKs, as discussed herein for both PXI, LXI, and AXIe-based systems. Any of the DAK embodiments described herein may include an interconnect chosen from rigid PCB, a flexible PCB, a rigid wire support or semi-rigid support, a short run fixed wire support, a combination thereof, and the like. Regardless of the removable DAK assembly, the module will typically include a mating face, i.e. a connecting lip on the connecting face 204, that is generally removably secured to the opposing rails 260a, 260b in a variety of configurations along the lengths, while allowing the DAK to be selectively positioned on the receiver 46 with its pull-through body extending beyond the universal assembly of the receiver 46.
FIG. 12 shows the mating side 52 of a universal receiver 46 embodiment capable of retaining a plurality of vertical and horizontal DAK modules. The upper tier includes the upper rail 258a and the lower rail 258b, which spaces the vertical interconnect modules 214, e.g. any of the modules described and shown herein. The lower tier includes a pair of left rails 260a and right rails 260b to space the horizontal interconnect modules 212, e.g. any of the modules described and shown herein. The intermediate middle wall 26 generally divides the upper tier and lower tier. Similarly, the filler plate 194 generally divides the pair of left 260a and right rails 260b in the horizontal instrumentation platform that is housed in the lower tier. Other examples include no filler plate and/or horizontal modules extending the length of the receiver, i.e. a single opening in the horizontal instrumentation platform 202; while other examples include multiple filler plates 194 to generally separate the instrumentation platforms into a variety of openings.
FIG. 13 shows the universal receiver 46 with the vertical and horizontal modules removed. As illustrated, the upper rail 258a and the lower rail 258b include a variety of fastener apertures 272 along the length of the rails to generally space and secure the vertical DAK modules in a variety of predetermined position to match and mate with corresponding testing equipment. In particular examples, the fastener apertures 272 are spaced along the entire length of the upper rail 258a and the lower rail 258b. Further, each of the left rails 260a and right rails 260b include a variety of fastener apertures 270 along the length of the rails to generally space and secure the horizontal DAK modules in a variety of predetermined position to match and mate with a corresponding piece of testing equipment. In particular examples, the fastener apertures 270 are spaced along the entire length of each of the left rails 260a and right rails 260b. Therefore, the receiver is further universal because the fastener apertures along the various rails provide a plurality of spacing arrangement options to match and mate with a variety of testing equipment configurations.
FIG. 14 generally shows the vertical and horizontal pull through bodies 210 extending beyond the front face, including the vertical instrumentation platform 200 and the horizontal instrumentation platform 202, of the universal receiver 46. In particular examples, the vertical and horizontal pull through module bodies are DAKs.
In yet further embodiments, any of the assemblies shown and described herein may be electronically engaged to instrumentation for enhancing the organizational and interchangeable electrical engagement between a test adapter and automated testing equipment. In particular examples, the system includes a LXI-based instrumentation, PXI-based instrumentation, an AXIe-based instrumentation and a combination thereof. In this way, embodiments and examples herein unexpectantly enhance connectivity to a wide variety of platforms not yet recognized by those skilled in the art, while allowing for the reduction of complex conventional wiring assemblies.
