The present invention relates generally to electronic interconnects and, more particularly, to adapters available for interconnects for high speed signal transmission and control thereof.
Electronic test and measurement instruments are used to test electronic circuits and devices. Typically, a measuring device such as a digital analyzer or an oscilloscope is used, and the measuring device is brought into contact with the measuring device by connecting the electronic probe or the optical probe to the measuring device via a cable. Is being tested. A connector at one end of the cable is inserted into a receptacle on the front of the measuring instrument, and a high frequency signal is transmitted from the circuit on the probe to the circuit of the measuring instrument.
In addition to the main high-frequency signal transmitted by the cable, other data signals are also transmitted between the probe and the measuring instrument to supply power and control signals to the probe and to enable the measuring instrument. The high frequency signal is actively monitored only at the selected time point. Such systems use multiple contact connectors, with several data contacts near the coaxial connector in the measurement instrument / probe interconnect. Existing systems commonly use BNC connectors for high frequency cables, where the connector housing of the cable supports several pogo pins that extend into the conductive lands (terminal areas) of the measuring instrument. In order to fix and align the cable, the BNC connector verifies its effectiveness. Some sampling oscilloscopes and other devices use SMA connectors to connect buses independently for power and data control signals.
Reverse compatibility is a problem for measuring instruments with standard BNC or SMA type connectors without power and data contacts. For example, active FET probes such as P6205 and P6217 manufactured by Tektronix, Inc. (hereinafter simply referred to as Tektronix) of Oregon, USA have a number of contact connectors in the vicinity of the BNC coaxial connector. In order to use this type of probe with a measuring instrument without using an interface, the TEKPROBE (registered trademark) power supply of the 1103 oscilloscope manufactured and sold by Tektronix is a power contact without using a special mechanism. And data line contacts can be used with the measuring instrument. The 1103 type TEKPROBE® power supply has a first interface connector attached to the power supply, the first interface connector having a BNC type connector and an adjacent contact, and a power contact and Compatible with probes with data contacts. A second standard BNC connector is also attached to the power source. The power source has a center conductor coupled to the center conductor of the first BNC connector. The power supply further includes a voltage offset potentiometer and an on / off switch. The power cable supplies power to the power source. The BNC / contact connector of the block is connected to the first interface connector, and the coaxial cable adapted to the BNC connector is connected to the second BNC connector and the input BNC connector for measurement equipment. The voltage power to the probe is supplied by a 1103 type power supply together with the probe offset control voltage. However, this power supply does not supply the data stored in the probe to the measuring device, and the measuring device does not control the probe.
The BNC interconnect has a rigid sleeve on each side. These sleeves fit together in the telescope's barrel and limit the angular placement of the cable connector from the connector attached to the chassis. Since the probe cable has a heavy housing at the connector end to accommodate the electronic circuit, a strong mechanical support is important. Further, the BNC connector has a bayonet connection system that provides rotational alignment of the connector housing. This is used to prevent unwanted withdrawal. To be effective in a certain high frequency range, the BNC connector degrades the signal for frequencies of about 1 to 3 GHz or higher depending on system requirements and circuit design.
Therefore, using a connector that allows another high frequency, signal integrity is guaranteed for frequencies above this range. Some types of screw connectors, such as the SMA standard, are suitable for high frequency performance (about 12-20 GHz), but screw connectors are not suitable for use with other data connectors. This is because the connector housing and data contacts interfere with the access necessary to rotate the screw connector portion. Push-on or blind mate connectors, such as the BMA standard, have adequate high frequency performance and prevent screw connectors from becoming incompatible with surrounding data connector housings.
However, the BMA connector may be damaged when it is angularly arranged with a force of an appropriate level or more, and an arbitrary latch or holding mechanism cannot be provided. The shield or ground contact of the female portion (female side) of the BMA connector has a cylindrical chamber with an inner sidewall that is engaged by a small leaf spring that fits into the inserted male shield contact. This alignment and flexibility achieves high frequency performance even with slight angular misalignment. However, the delicate leaf spring contact is broken by an appropriate angular force on the connector, and the BMA connector is not stable in a laboratory where a protruding connector collides or a heavy pressure is applied.
Therefore, according to the present invention, even if the probe connector does not correspond to the connector of the measuring device, the probe can be connected to the measuring device, and electronic data related to the probe can be transmitted, so that the connector can be aligned properly It is possible to provide an adapter for an electronic interconnect assembly that is resistant to forces on the connector.

FIG. 1 is a perspective view of an electronic measuring instrument such as a digital oscilloscope 10 having a probe 12 connected to test a circuit under test or device 14. The probe 12 includes a cable 16 that extends to a probe interconnect housing 20. Cable 16 preferably includes a single coaxial wire (cable) having a central signal conductor and an ambient ground or shield conductor. The cable 16 further includes a multi-line bus for transmitting control signals and power between the probe 12 and the measuring instrument 10. The housing 20 is removably connected to one of several interconnecting receptacles 22 on the measurement instrument front panel 24.
2, 3, 4 and 5 show the mechanical elements for implementing the electronic interconnect assembly used in the adapter for electronic interconnect assemblies according to the present invention. 2 is a perspective view of a probe interconnection part according to a preferred first embodiment of the present invention, and FIG. 3 is a perspective view of a chassis interconnection part according to a preferred first embodiment of the present invention. FIG. 4 is a perspective view of the probe interconnect portion and the chassis interconnect portion according to the first preferred embodiment of the present invention, but the probe interconnect portion is not all of the components shown in FIG. FIG. 2 also shows a portion that cannot be seen due to the viewing angle, and the chassis interconnection portion is as seen from the back of FIG. FIG. 5 is a perspective view of a probe and chassis interconnection portion having a notch and rib structure different from the first embodiment according to a second preferred embodiment of the present invention. As shown in FIG. 2, the probe interconnection housing is terminated by an interconnection body (an alignment mechanism portion having a tightly fitting body) 26. The interconnect body 26 includes electrical connectors that effectively transmit high-speed signals and data, and has structural alignment characteristics for securely and in-line mechanically connecting to the measuring instrument. The body 26 is preferably a moderately stretched rigid member formed of a sturdy material such as nickel-plated zinc, die-cast aluminum, or the like. The body 26 has a trailing edge surface 30 coupled to the probe interconnect housing 20 and a parallel leading edge surface, ie, a nose 32, perpendicular to the connector shaft 34 and facing away from the trailing edge surface 30. . The remaining upper wall 36, lower wall 40, and side walls 42, 44 have a substantially rectangular cross section of the main body 26, and the length of the main body 26 between the leading edge surface 32 and the trailing edge surface 30, except for the features described below. Minimize the range of change. The body 26 is tapered so that the leading edge surface (nose) 32 is slightly smaller for ease of manufacturing in the casting process and for a tightly fitting machine connection.
The body 26 has an alignment notch 46 in each of the side walls 42, 44. Each contour of the notch 46 is an elongated trapezoid extending from the leading edge surface 32 and extends parallel to the axis 34. Each end of the notch 46 has a shoulder guide 47 manufactured with precise size tolerances to fit snugly with the end of the corresponding key, as described below. The notch 46 is offset from the horizontal centerline of the main body 26 and prevents the main body 26 from being inserted at a position rotated 180 degrees relative to the interconnection receptacle (alignment mechanism portion having a pocket) 22. As can be seen from FIG. 4, the main body 26 has an alignment key 50 on an upper wall (upper surface) 36 and a lower wall (lower surface) 40. These keys 50 are made with precise size tolerances to closely fit the ends of the corresponding notches, as described below. Since the shoulder guide 47 and the alignment key 50 are aligned with the front edge surface 32, the guide 47 and the key 50 are aligned simultaneously with the corresponding key and notch of the receptacle 22.
An opening is provided in the upper surface 36 of the main body 26, and a spring-loaded cam lock 52 projects through the opening. The cam lock 52 has a leading edge that is flush with the surface 36 and is inclined toward the trailing edge of the protrusion. Since the lock button 54 extending from the housing 20 is mechanically engaged with the lock 52, pressing the button 54 causes the lock 52 to be retracted into the main body 26. Can be connected.
Upper surface 36 and lower surface 40 have latch ramps 56 that are opposed and positioned symmetrically. Each of these inclined portions 56 has an inclined front edge inclined surface 60 and an inclined rear edge inclined surface 62. These ramps become progressively higher and meet at the peaks, i.e. the top 64. The top 64 is slightly rounded. Since these inclined surfaces 60 and 62 are recessed with respect to the upper surface 36, the top portion 64 does not protrude above the upper surface 36. Each top 64 has a line parallel to the surfaces 36, 40 and parallel to the front edge surface 32 of the body 26. In addition, the top 64 is parallel to the surfaces 36 and 40 so that it can be inclined. Preferably, the inclined surfaces 60, 62 and the top 64 are formed with a smooth, polished surface finish to reduce wear during the latching operation described below.
The front edge surface 32 of the main body 26 is provided with two different openings for electrical connectors. The first opening 66 allows access to a printed circuit board 70 provided inside a chamber provided in the main body 26. The printed circuit board 70 has a contact surface that is accessible through the opening 66. The printed circuit board 70 is connected to circuitry and / or probes in the housing 20 and has an array of exposed conductive lands. As will be described later, some of these lands can be connected to a mating connector in contact with the lands in an electrically distinguishable pattern. This option allows the measuring instrument to properly identify the probe connector even if the data land is not connected to a less complex but compatible probe or other circuit. Alternatively, the probe circuitry may comprise an EPROM or other non-volatile device to perform the identification function.
A male side 72 of a standard BMA or blind mating connector, such as that manufactured and sold by the M / A-Com division of AMP Inc. of Lowell, Massachusetts, USA, is provided in a recess 74 formed in the body 26. This BMA male side (high speed coaxial interconnection) 72 extends parallel to the shaft 34. The BMA male side 72 includes a shield sleeve portion (peripheral shield conductor, male shield contact) 76 having a tapered outer portion 80 at the free end, which is slightly in front of the leading edge surface 32. Extends to the retracted level to prevent damage to the connector. The center signal conductor 81 has a base 82 and an extended free end portion 84 that is coaxial with the shield sleeve portion 76. The free end portion 84 has a smaller diameter than the base 82 and the shoulder 86 faces the main direction. The free end of the center signal conductor 81 is retracted in front of the shield portion 76 to prevent damage, and as will be described later, even if the signal conductor 81 is in contact or non-contact, the shield is surely performed. . That is, the shield contact is performed before the signal conductor 81 contacts, and the shield contact is still performed immediately after the signal conductor 81 is detached.
FIG. 3 shows the receptacle 22 attached to the measuring instrument. The receptacle 22 is a rigid plastic body, die cast aluminum, etc., which forms the female side of the connector and receives the probe interconnect body 26. The receptacle 22 is a pocket or box type main body, and its open side faces away from the measuring instrument front panel 24. This open side also faces the floor panel 94 and is essentially a cylinder with a rectangular cross section. The receptacle 22 shown more clearly in FIG. 4 is formed with a retaining nut channel (groove) 170. Each of these channels 170 has a bore (hole) 172. A retaining nut 174 is retained in each of the channels 170 and the threaded bore of the nut is aligned with the corresponding channel bore 172. The floor panel 94 is preferably a forged metal sheet, and has through-holes only to the extent necessary to provide fastener holes and electrical connector holes to prevent EMI leakage. . A screw bolt (not shown) passes through the fastener hole and is screwed into the retaining nut 174 to secure the receptacle 22 to the front panel 24.
The receptacle 22 has a rim 90 protruding from the panel 24 and also has a side wall 92 extending from the rim 90 and the panel 24 to a floor panel 94 that is well recessed. Each side wall 92 has an extension key 96 that extends from the rim 90 to the floor panel 94. The dimensions of the ends of each of these keys 96 are accurate so as to closely receive the corresponding shoulder guide 47 in the notch 46 of the probe connector body 26. Therefore, the notch and the key are mechanical alignment. The length of the notch 46 in the body 26 is large, as will be described later, so that the key 96 does not stick to the bottom in the notch 46 before the BMA connector is fully connected. In addition, the depth of these notches 46 recessed below the surfaces of the side walls 42, 44 is slightly too deep, leaving a suitable gap between the keys 96. The receptacle 22 also includes notches 98 formed in the top and bottom of the rim 90, which coincide with the keys 50 (FIG. 4) of the body 26. The widths of shoulder guide 47, key end 97, key 50, and notch 98 are adjusted tightly so that body 26 relative to rim 90 of receptacle 22 even if the overall dimensions of body 26 and receptacle 22 are not precise. Can be accurately positioned in both vertical and horizontal directions.
The keys and notches in the receptacle 22 and body 26 can be reversed as shown in FIG. 5 of the second embodiment of the present invention. In the second embodiment, the main body 26 has an alignment key 220 on each of the main surfaces 36, 40, 42, 44 of the main body. Each of the keys 220 has an elongated rectangular profile and extends parallel to the axis 34. These keys 220 are manufactured with precise size tolerances to fit snugly with the corresponding notches, as described below. The keys 220 are aligned with each other so that the leading edge ends 222 of all of the keys are equally spaced from the leading edge surface (nose) 32. Each side wall 92 of the receptacle 22 is provided with an elongated notch 224 extending from the rim 90. Each of these notches 224 is accurately sized to closely receive the corresponding key 220 of the probe interconnect body 26. The length of each notch 224, i.e., the depth of notch 224 extending into the chamber of receptacle 22, is large, so that key 220 is not Does not stick to the bottom. In addition, the depth of these notches 224 recessed below the panel in which the notches 224 are formed is slightly deeper, creating an appropriate gap with the key 220. Similar to the first embodiment, the widths of these notches and keys are precisely adjusted so that the body 26 relative to the rim 90 of the receptacle 22 is not critical even though the overall dimensions of the body 26 and receptacle 22 are not critical. Positioning can be performed accurately. As another example, both sides may have both a notch and a key, with the opposing sides having opposite counterpart elements (key for notch and notch for key).
Therefore, the arrangement of the notch and the key enables insertion and extraction along the shaft 34. However, the degree of freedom in two directions determined by the front panel surface 24 and the degree of freedom of rotation around the shaft are lateral. Movement is restricted. As described below, the remaining freedom of movement (along the axis) is limited by the latch mechanism, and the remaining rotational freedom (from the front panel vertical to the probe connector body sideways and horizontal bending) is connected. Limited by BMA connector.
Reference is again made to FIG. FIG. 4 representatively shows a protrusion 176 protruding from the front edge surface 32 of the interconnect body 26. The protrusion 176 coincides with a corresponding opening 178 formed in the tab 180 formed in the receptacle 22 and extending downward. Protrusions 176 and openings 178 prevent incompatible probe connectors from properly connecting to the measuring instrument. The position of the protrusion 176 of the interconnect body 26 corresponds to the position of the opening 178 to allow insertion of the receptacle 22. In FIG. 4, two protrusions 176 and openings 178 are shown, however, protrusions and openings may be provided in the interconnect body 26 and receptacle 22 to provide a family of interconnects with different key arrangements. In the interconnect body 26, an array of protrusions may be realized along with an array of openings that receive elongated studs (studs) that extend beyond the front edge surface 32 of the body 26. These studs can be arranged in an array that produces many unique patterns. An array of openings can be realized in the tab 180 of the receptacle 22. Moreover, you may insert a plastic insertion (insert) in the opening which does not respond | correspond to the implantation bolt arrangement | positioning of a protrusion arrangement | sequence. In this case, the interconnect body 26 having a stud bolt arrangement that does not correspond to the aperture array cannot be electrically connected to the interconnect receptacle 22. Many possible positions of protrusions and openings and the option to use protrusions or openings on either side of the connector ensure that only the probe of interest is connected to a given receptacle in a great number of configurations it can.
Another configuration of the aperture array may remove the tabs 180 from the receptacle 22 to form an aperture array in the front panel 24 of the electronic measurement instrument 10. In this case, the studs in the protrusion array extend into openings in the front panel 24. A plastic or metal insert is inserted into the opening in the front panel 24 to form an array of stud bolt pattern of protrusions. As can be seen, the studs in this structure are longer than those in the above-described embodiment.
Refer to FIG. 3 again. A symmetrically opposed pair of spring loaded latches 100 project vertically into the chamber of the receptacle 22 through openings provided in the top and bottom walls of the receptacle. These latches 100 engage with the latch inclined portions 56 of the main body 26. Each latch 100 has a roof shape with an inclined surface toward the rounded top ridge, the inclination being selected to coincide with the surface of the latch inclined surface 62 of the body 26. By selecting these inclinations, a small insertion force and a large extraction force can be obtained by using the gentle inclination of the inclined surface 60 and its corresponding latch surface instead of the inclined surface 62 and its corresponding latch surface. The rounded top of the body 26 and receptacle 22 interface and the tight mechanical tolerances ensure that the latch 100 does not become stable near the top. Here, one latch is on the insertion side of the top and the other latch is on the withdrawal side. Thus, as described below, the latch ensures that the connector is fully connected or properly pulled out and prevents unwanted partial electrical contact.
Two electrical connector components are attached to the floor panel 94 in the receptacle 22, each component being a piece of the connector of the body 26. A spring-loaded pogo (pogo: stilt-like cross with one end) pin (compliant contact) connector (electronic data interconnection portion) 102 array is arranged on a circuit board (electronic data interconnection portion) 70 land. Position it so that it matches the (fixed surface contact). These pins of the connector 102 are in range of motion with the appropriate spring bias force, allowing the BMA connector to be free with respect to the depth of insertion for connection. The female side (high speed coaxial interconnect) 104 of the BMA connector is mounted on the floor panel 94, which is shown in detail in FIG. FIG. 6 is an enlarged cross-sectional view along the connector axis. This connector has a cylindrical shield sleeve 106 and forms a cylindrical chamber 107.
The floor and side walls of the chamber 107 are aligned with the leaf spring sleeve 110. Side springs (ambient shield conductors) 112 are slightly bowed toward the chamber, and end spring portions (ambient shield conductors) 114 are bowed from the floor to the chamber. These side springs 112 and end spring portions 114 are also compliant portions. Even if the male shield sleeve portion 76 is somewhat angularly dislocated, the side spring 112 grips the male shield sleeve portion 76 straight. For the BMA standard, a deviation of up to 5 degrees can be tolerated without connection degradation. However, such deviations may damage delicate springs as described above. The end spring portion 114 is in direct contact with the end surface 116 of the male shield sleeve portion 76 to allow a small range of insertion depths so that the insertion depth due to the signal connection can be accurate. The center signal conductor 120 is a rigid sleeve having a bore 122 sized to closely receive the free end portion 84 of the male signal conductor 81. A compliant spring portion (not shown) is aligned with the bore for effective ohmic contact.
The center signal conductor 120 includes a free end surface 124 that is recessed to an appropriate depth below the free end surface 126 of the shield sleeve 106 to provide protection against damage. Further, the shield sleeve 106 extends to an appropriate distance with respect to the signal conductor 120 so that when signal contact is made, the shield contact is already made and when the signal contact is removed, the shield contact is still made. Make sure.
By inserting the main body 26 into the receptacle 22, the key 96 of the receptacle 22 is positioned at the notch 46 in the main body 26. The male shield sleeve portion 76 enters the female tubular chamber 107 by continuously inserting the body into the receptacle 22. The compliant side spring 112 grips the male shield sleeve portion 76 so that the free end portion 84 of the male signal conductor 81 is aligned with the bore 122 of the female center signal conductor 120. By continuously inserting the main body 26 into the receptacle 22, the end 97 of the key 96 engages with the shoulder guide 47 of the notch 46. Similarly, the top and bottom keys 50 (FIG. 4) of the body 26 engage with notches 98 in the rim 90. As will be described later with reference to FIG. 8, when the shoulder 86 is pushed against the free end surface 124 of the female signal conductor 120, the connector is completely inserted. Further, when the shoulder 86 is pushed against the free end face 124 of the female signal conductor 120, the end face 116 of the male shield sleeve portion 76 pushes the end spring portion 114 of the leaf spring sleeve 110. This biasing force is provided by a spring latch.
FIG. 7 is a detailed exploded perspective view of the interconnect portion according to the first preferred embodiment of the present invention (inverted from FIG. 4). Lock 52 and button 54 are coupled to lock frame 126 and are slidable relative to housing end plate 130 attached to housing 20 and are attached to body 26. Since the rear 132 of the male side of the BMA connector 72 passes through the hole in the plate 130, the rear 132 extends into the housing 20 and is connected to a circuit or cable within the housing. The rear 132 is illustrated with a standard SMA threaded connector, but any form including BNC, BMA, N or any high frequency capable connector may be used. Although the latch inclined portion 56 is illustrated, the inclination is different when a pulling force larger than the insertion force is required.
The spring latches 100 are respectively attached to the extension bars 134. Each bar 134 extends slightly beyond the width of the receptacle 22, with one bar above the top surface and the other bar below the bottom surface. These bars are positionally limited by channel walls 135 extending from the top and bottom surfaces of the receptacle 22. A coil tension spring 136 is positioned on each side of the receptacle 22 and the end of each spring 136 is coupled to the extended end of the bar 134 to bias the bars together. Thus, the biased bars 134 bias the latches 100 toward each other. In this embodiment, the latch 100 is plastic and is integrated with an elongated plastic beam (beam) that receives the metal reinforcement bar 142. Alternatively, a fixed spring retaining surface may be provided on the latch 100 and a compression spring is captured between the spring retaining surface and the latch 100. A recess 141 is formed in the receptacle sidewall after the spring 136. Here, a high density foam insert 143 is received. This insert 143 is manufactured and sold by Roger Corporation of East Woodstock, Connecticut, for example. The insert 143 eliminates excessive spring noise while the body 26 is inserted into or removed from the receptacle 22.
FIG. 8 shows a cross-sectional view of the connector in a fully inserted state. Interconnect cable 144, preferably a flexible circuit, is connected to circuit board 70. The circuit board 70 is mechanically fixed to the main body 22 by screws, caulking, or the like. Data and power cables are connected to circuitry (not shown) in the probe interconnect housing 20. The pogo pin connector 102 is fixed to a lead wire extending to the measuring instrument, and the lead wire is soldered to the circuit board 146. A data cable 150 is extended and connected to circuitry within the measurement instrument 10. Alternatively, the pogo pin connector 102 may be soldered directly to the front panel circuit board. The probe cable 16 is connected to the male side 72 of the BMA. In FIG. 8, the shoulder 86 (FIG. 2) is in complete contact with the surface of the female signal conductor 120 (FIG. 3). The measuring instrument signal cable 152 is connected to the back side of the female side 104 and contacts a circuit in the measuring instrument. To bias the male side shoulder 84 of the BMA with respect to the face of the female center conductor 120, the latch is arranged so that the latch 100 does not bottom out with respect to the plane of the body 26, but pressure is exerted on the tilted inclined face 62. Add This creates the axial bias force necessary to ensure proper high frequency connection.
A spring bias is applied to the lock frame 126 by a coil compression spring 154. The spring 154 is captured between a fixed arm 156 extending axially from the plate 130 and a portion of the lock frame 126. The lock 52 and the notch 160 engage with each other so that they are not pulled out accidentally. This locking mechanism is independent of the latch mechanism. That is, the combination of the spring latch 100 on the receptacle 22 and the latch ramps 60 and 62 on the interconnect body 26 ensures that the interconnect body 26 is secured within the receptacle 22 without the lock 52 and button 54. Give proper latching force. In the preferred embodiment, the locking mechanism is provided as a secondary protection to prevent accidental removal of the probe interconnect housing 20 from the electronic measurement instrument 10. This locking mechanism is also unique, and is a “fail safe” function. If the user attempts to remove the device without pressing the lock button 54, the locking mechanism causes the cam to disengage and the device to be released before breaking the locking mechanism or holding mechanism. This is controlled in part by the tilt angle on the front of the movable part of the locking mechanism. Depending on the probe application, a locking mechanism may not be used in the probe interconnect housing 20.
FIGS. 9A, 9B, and 9C show different connector adapters 200A, 200B, and 200C according to the present invention that are configured to interface with standard connectors that can be connected to the custom connector receptacles of the preferred embodiment described above. As a result, a signal can be supplied to the measuring instrument even with a general probe or other circuit under test connection device that is not designed for the present invention. In particular, high frequency connectors are of the BMA type and are not suitable for probes that do not require other assistance for bending and sudden withdrawal, so other probe types that are not BMA type are required for such probes. It becomes. Thus, each adapter in the preferred embodiment according to the present invention comprises a standard pocket and mating body 26 having the same male BMA connector, latch, and optional lock. Since the illustrated adapter may not require additional data lines, the circuit board 70 need not be connected to the cable 144 as in the preferred embodiment described above. However, since a fail-safe measure can be taken to ensure operation only when the connector is properly inserted, the circuit board may be selectively connected between two or more lands. . In addition, the measurement device may be informed that an appropriate connector is arranged based on information stored in an EPROM or other nonvolatile memory provided in the adapter.
In the preferred embodiment shown in FIG. 9, the housing 20 is replaced with a smaller housing and the probe cable connected to the BMA male side 72 is eliminated. However, in adapter 200A, a female SMA connector input end 202 is provided and connected to the BMA male side opposite the input end 202 via a high speed coaxial interconnect portion having a central signal conductor and a surrounding shield conductor. In addition, the adapter 200B is provided with a female BNC connector input end 204 and is connected to the BMA male side portion 72 opposite to the input end 204 via a high-speed coaxial interconnection portion. This female BNC connector input 204 is compatible to support existing signal or multiline connector structures such as those used in the P6139A and P6245 models manufactured and sold by Tektronix, Inc. of Beaverton, Oregon, USA For this purpose, a power and data interface may be included. In adapter 200C, female N connector input 206 is provided and connected to BMA male side 72 opposite to input end 206 via a high speed coaxial interconnect. When connecting a heavy cable to an N connector, etc., a pair of thumbscrews are optionally provided to provide a stronger connection to the measuring instrument, and a female screw hole or PEM (trademark) in the front panel of the measuring instrument ) May be engaged with nuts. In the preferred embodiment, the male BMA connector is a sufficiently long custom screw mechanism component so that various connectors can be provided on the housing surface. Alternatively, standard BMA connectors with SMA connector ends may be used with various adapter connectors such as SMA to BNC connectors, SMA to N connectors.
In FIG. 9C, to avoid excessive torque damaging the front panel, the thumbscrew has a camming surface to prevent the use of a screwdriver during insertion. When the fastener (the thumbscrew) is tightened, or when a non-dexterous user needs to remove the screw, a tool for removing the screw can be used as necessary. These screws, unlike commonly used screws, prevent destruction and breakage of the general structure. In this case, these screws facilitate removal with the aid of the tool but prevent tightening with the aid of the tool.
In FIG. 9D, adapter 200D performs the conversion to use the probe designed for the preferred embodiment of the present invention described above, together with a measuring instrument having a common input such as BNC, SMA or N type. It is. This adapter 200D is provided with a receptacle 22 on one side (the back side in the figure), and the BMA female side portion of the above-described preferred embodiment is provided there, but it may not be attached to the chassis. The conventional male connector 212 extends from the opposite side (the front side in the figure) and is connected to the female connector of the measuring instrument. Between the conventional connector 212 and the BMA female side is a high speed coaxial interconnect. A female connector may be provided instead of the male connector 212, and a cable end portion having a male connector at both ends may be inserted between the adapter 200D and the measurement instrument input. For clarity, the spring and latch bar are shown exposed, but in the preferred embodiment, a shroud surrounds these components to prevent breakage and provide a smooth appearance.
FIG. 10 is an exploded perspective view in which the adapter 200D of FIG. 9D is modified, and the transmission cable 230 supplies at least voltage power to the adapter. Transmission cable 230 also has other electrical wires that are connected to each contact of an electrical interconnect, such as circuit board 232. The contacts on the circuit board 232 are electrically coupled to fixed leads extending from the pogo pin connector 102 in the receptacle 22 of the electrical interconnect assembly. The surrounding shield conductor and center signal conductor of the BMA connector 104 in the receptacle 22 are connected to the corresponding shield conductor and center signal conductor of an electrical signal connector 234, such as an SMA or BNC connector. The other end of the transmission cable 230 is connected to a second electrical interconnect suitable for the specific voltage power interface available. For example, the second electrical interconnect portion may be a DIN type connector 236 that matches a corresponding DIN connector in the measuring instrument. Another type of interconnect may be the BNC type connector 238 described above, with the connector housing 240 surrounding several pogo pins 242. These pins 242 extend outwardly from the housing 240 adjacent to the connector 238. The BNC connector matches the corresponding BNC connector on the measuring instrument, and the pogo pin 242 contacts the conductive land of the measuring instrument. In addition, voltage power is supplied from the measuring device to the land of the connector. A BNC type connector having pogo pins can also be connected to an input connector 204 of an adapter 200B as shown in FIG. 9B. In this case, the main body 26 of the adapter 200B is inserted into an electrical interconnection receptacle 22 provided in the measuring instrument, and the land of the circuit board 70 in the main body 26 is spring loaded Pogo pin 102 within the receptacle 22. Matches.
It is also necessary to check the performance of the end device by connecting an end device such as a measurement probe to a measuring instrument that does not have the electrical interconnection of the present invention. For example, it is necessary to connect the probe to a wide bandwidth sampling oscilloscope to see the bandwidth / rise time of the probe and to be able to change the parameter data stored in the EEPROM within the probe. FIG. 11 shows an adapter having a first adapter portion 250 as shown in FIG. The first adapter portion 250 is connected to the second adapter portion 252 via the transmission line 254. Transmission line 254 includes a data line that passes data between a host measurement instrument having an electrical interconnect and a probe having an electrical interconnect. The body portion of the probe interconnect portion is connected to the receptacle portion 256 of the first adapter 250. The female side (high speed coaxial interconnect) 258 of the BMA connector in the receptacle portion 256 is connected to an electrical signal connector 260 that has characteristics that emulate the characteristics of the BMA connector as much as possible. One such connector is an SMA connector. This electrical signal conductor is connected to a corresponding connector of the measuring instrument. The second adapter portion 252 includes a body portion 262 of the electrical interconnect portion and is connected to a receptacle portion of the body portion of the host measuring instrument. This host measuring device communicates with the probe via the adapter and the data line of the transmission cable. Probe data such as calibration constants and calibration data stored in the probe EEPROM can be read and changed by the host measuring instrument.
Although preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, the electrical connector may be positioned on a different side of the connector. If a Pogo pin connector is provided on the probe side, the probe may be damaged if it comes in contact with other hardware or is dropped when housed in the drawer (risk) In order to reduce this, a pogo connector may be provided on the side of the measuring instrument. However, if it is necessary to inspect or replace the pogo connector, the pogo connector may be provided on the side of the probe. Note that this is more practical for the probe than for the measuring instrument. Similarly, the male and female sides of the BMA may be exchanged as needed. The pogo and BMA connectors may be provided as independent structures.
Although the present invention has been shown with respect to a fixed female BMA connector, it is possible to use a floating or spring loaded connector component for embodiments having a single or multiple BMA connections in a single probe connector housing. It is possible and adapted to position variations between the connectors of the housing. However, this requires a flexible cable that connects each of the floating BMAs in the measuring instrument housing. This complicates the internal wiring of the measuring device. Further, when the cable of the measuring device is connected to another circuit, there is a possibility that fatigue or damage may occur due to movement. Therefore, it is preferable to use a single BMA connector for a fixed connector of a measuring instrument.
By providing an alignment mechanism such as a key and a notch, accurate alignment can be realized within a variation of tolerance of less than 0.5 degrees. This is adequate to achieve nominal signal performance with the BMA connector and can protect against damage due to excessive shaking. Although it is possible to achieve a tighter tolerance, there is also the advantage that some minimal blur can be tolerated. In this case, the connection needs to “scrubb” the pogo pins against the lands to provide a low resistance contact and to remove or wear the high resistance layer or debris of the lands. The key and notch mechanism (alignment mechanism) may be eliminated as a whole, however, it can reduce blurring or increase blurring within an acceptable range of about 1-2 degrees. When inserting a large number of connectors into a measuring instrument, more accurate alignment is desirable in order to ensure quality within a suitable range and a uniform appearance. In addition, even if a part of the key and notch is damaged or lost, there is a guarantee of proper alignment.
Although the preferred embodiment of the present invention has been illustrated and described in connection with a BMA connector, the principles of the present invention can be applied to various types of connectors. Other principles of the present invention are also applicable to any coaxial high speed connector without screw fastening. Further, the present invention can be applied to a compliant contact sleeve, an insertion depth detection connector such as a shoulder contact, and any connector that does not support a lateral bending load.
As described above, according to the adapter for electronic interconnection assembly of the present invention, even if the connector of the probe does not correspond to the connector of the measuring device, the probe can be connected to the measuring device, and electronic data related to the probe can be transmitted. The connector can be reliably aligned, and it is resistant to the force applied to the connector.
