BACKGROUND

[001] The present invention generally relates to apparatuses for interconnecting circuit boards or other electrical components.

SUMMARY

[002] Embodiments of the present invention provide a modular approach for blind mate interconnects. In one aspect, the invention provides a connector assembly that includes an adapter assembly and a header assembly configured to connect directly to a circuit board and configured to blind mate with the adapter assembly.

[003] In some embodiments, the adapter assembly comprises: an adapter housing; a first insulator in the form of a generally rectangular solid block having a plurality of through holes; a first set of contacts, each contact in said first set being disposed in one of said though holes such that and an end portion of the contact extends beyond a surface of the first insulator, which end portion is configured to mate with a corresponding contact of the header assembly; a second insulator in the form of a generally rectangular solid block having a plurality of through holes; and a second set of contacts, each contact in said second set being disposed in one of said though holes of said second insulator such that and an end portion of the contact extends beyond a surface of the second insulator, which end portion is configured to mate with a corresponding contact of the header assembly.

[004] In some embodiments, the header assembly comprises: a header housing; a third insulator in the form of a generally rectangular solid block having a plurality of through holes; a third set of contacts, each contact in said third set (a) having a first end portion and a second end portion, said first end portion being configured to mate with a corresponding element of the circuit board and the second end portion being directly connected to a contact from the first set of contacts and (b) being disposed in one of said though holes such that the first end portion of the contact extends beyond a surface of the third insulator; a fourth insulator in the form of a generally rectangular solid block having a plurality of through holes; and a fourth set of contacts, each contact in said fourth set (a) having a first end portion and a second end portion, said first end portion being configured to mate with a corresponding element of the circuit board and the second end portion being directly connected to a contact from the second set of contacts and (b) being disposed in one of said though holes such that the first end portion of the contact extends beyond a surface of the fourth insulator.

[ 005 ] In some embodiments, a float plate is attached to the adapter assembly.

The float plate may be configured to floatably connect the adapter assembly to a frame.

[ 006 ] Advantageously, in some embodiments, the adapter housing comprises means for facilitating alignment of the header assembly with the adapter assembly, the header housing comprises means for facilitating alignment of the header assembly with the adapter assembly, and the third and fourth insulator each comprises means for facilitating alignment of the header assembly with the adapter assembly.

[ 007 ] The above and other aspects and embodiments are described below with reference to the accompanying drawings.

[ 008 ] The accompanying drawings, which are incorporated herein and form part of the specification, illustrate various embodiments of the present invention and, together with the description, further serve to explain the principles of the invention and to enable a person skilled in the pertinent art to make and use the invention. In the drawings, like reference numbers indicate identical or functionally similar elements.

[ 0010 ] FIGs. 27-39 illustrate a connector system according to another

embodiment of the invention.

[ 0011 ] FIGs. 40-42 illustrate a connector system according to yet another embodiment of the invention.

[ 0012 ] FIGs. 43-45 illustrate a connector system according to yet another embodiment of the invention. DETAILED DESCRIPTION

[ 0013 ] Referring now to FIG. 1, FIG. 1 illustrates a connector system 100 according to an embodiment of the invention. As shown, connector system 100 may include a first connector assembly 101a electrically connected to a second connector assembly 101b. Connector assembly 101a may be substantially identical to connector assembly 101b. As also shown, system 100 may include a plug 108 electrically connected to connector assembly 101b. Each connector assembly 101 (i.e., connector assemblies 101a,b) may include a header assembly 102 and an adapter assembly 104 (i.e., connector assembly 101a may include header assembly 102a and adapter assembly 104a and connector assembly 101b may include header assembly 102b and adapter assembly 104b). Each assembly 101 may also include a float plate 106 for connecting the adapter assembly 104 to a frame (e.g., a chassis) or other device. Float plate 106 may be configured to snap onto adapter assembly 104.

[ 0014 ] Referring now to FIG. 2, FIG. 2 is a top view of an exemplary connector assembly 101. As shown, header assembly 102 of the connector assembly 101 may include a header housing 202, and adapter assembly 104 may also include an adapter housing 204 for housing various insulators (i.e., housings that house contacts and electrically insulate the contacts from one another). In the example shown, adapter housing 204 is housing two power/RF insulators 211 and a signal insulator 212, the power/RF insulators 211 are housing two power contacts 220 and two signal contacts 222, and the signal insulator 212 is housing a number of signal contacts 222.

[0015] Referring now to FIG. 3, FIG. 3 is a bottom view of the exemplary connector assembly 101. In the example shown, housing 202 is housing two power/RF insulators 311 and a signal insulator 312, the power/RF insulators 311 are housing two power contacts 320 and two signal contacts 322, and the signal insulator 312 is housing a number of signal contacts 322. FIG. 4 is a side view of connector assembly 101.

[0016] Referring now to FIG. 5 , FIG. 5 is a view of an exemplary adapter housing 204. In the embodiment shown, housing 204 is a generally rectangular housing open at opposite side thereof having two end walls and two side walls, and the side walls include grooves 502 for receiving a locking tab 602 (see FIG. 6) formed on a side wall of an insulator. The depth of the groove 502 decreases as the groove 502 proceeds inwardly, thereby forming a ramp structure. This facilitates the locking of an insulator in the adapter housing. FIG. 6 illustrates three insulators and the locking tab 602. The locking tab 602 is configured to engage groove 502, as illustrated in FIGs. 7 and 8.

[0017] As shown in FIG. 6-8, insulators 211 and 212 are generally in the form of rectangular, solid blocks that include through holes for receiving a contact. For example, power/RF insulator 211 includes, in the embodiment shown, two through holes 611 each for receiving a power contact or RF contact and two through holes 612 each for receiving a signal contact. Likewise, signal insulator 212 includes, in the embodiment shown, eighteen through holes 614 for receiving eighteen signal contacts.

[0018] FIG. 9 is a top view of adapter assembly 104 and shows an exemplary signal contact 222 inserted into a through hole 614 of signal insulator 212. FIG. 9 also shows an exemplary power contact 220 inserted into a through hole 611 of power insulator 212. FIG. 10 is a bottom view of adapter assembly 104 and shows that an end portion of power contact 220 and an end portion of signal contact 222 passes entirely through the through holes 611 and 614, respectively. That is the end portions of contacts 220 and 222 extend beyond the bottom face of insulators 211 and 212, respectively. Insulators 211 and 212 and contacts 220 and 222 configured like this so that the end portions of the contacts can mate with corresponding contacts of the header assembly 102.

[ 0019 ] While in FIG. 9 adapter assembly 104 is shown has having two power insulators 211 and a single signal insulator 212 arranged between the power insulators, the invention is not so limited. In fact, an advantage of adapter assembly 104 is that it is extremely adaptable. That is, the type of insulators that may be housed in adapter housing 204 and the arrangement of said insulators in the housing is entirely up to the end user. Some users may desire three power insulators and no signal insulators, while others may prefer the opposite or some other combination and arrangements of insulators.

[0020] Referring now to FIG. 11 , FIG. 11 illustrates an exemplary signal contact 222. The exemplary signal contact 222 is elongate, has a conical tip 1102 (a.k.a., lead in 1102), and a open, crimpable end portion 1104 for receiving a corresponding electrical element (e.g., the end of a wire). In the example shown, end portion 1104 is in a crimped state and, therefore, has a generally C shaped cross section. In an uncrimped state, end portion 1104 would have a more U shaped cross section. FIG. 12 illustrates an

exemplary power contact 220, which, in the embodiment shown, includes a conical shaped lead-in 1202, which functions to facilitate alignment between assemblies 102 and 104.

[0021] Referring now to FIG. 13 , FIG. 13 illustrates an exemplary header assembly 102. Like adapter assembly 104, header assembly includes a header housing 202 for housing power/RF insulators 311 and/or signal insulators 312. In the example, shown, because adapter assembly 104 includes a signal insulator 212 sandwiched between two power insulators 211, header assembly 102 also includes a signal insulator 312 sandwiched between two power insulators 311.

[ 0022 ] FIG. 14 further illustrates header housing 202. Like adapter housing 204, header housing 202 includes a generally rectangular frame 1402 having two parallel end walls and two parallel side walls, and the side walls include grooves 1404 for receiving a locking tab (see e.g., element 602 in FIG. 6) formed on a side wall of an insulator. The depth of the groove 1404 decreases as the groove 502 proceeds inwardly, thereby forming a ramp structure. This facilitates the locking of an insulator in the header housing 202. As also shown, housing 202 includes two parallel side walls 1306, 1308 that face each other and extend outwardly from the end walls of housing 1402. FIG. 15 shows a signal insulator 312 that has been inserted into housing 202. Groove 1404 and lock tab 602 engage to releasably retain insulator 312 in housing 202.

[0023 ] FIG. 16 shows an exemplary signal contact 322 inserted into a through hole of signal insulator 312. FIG. 16 also shows an exemplary power contact 320 inserted into a through hole of power insulator 312. FIG. 17 is a cross-sectional view of assembly 102 according to some embodiments. In the embodiment shown, the end portion 1702 of contact is disposed within the though hole. That is, in the embodiment shown, end portion 1702 does not extend beyond the upper face 1704 of signal insulator 312. FIG. 18 further illustrates contact 312 according to some embodiments. In the embodiment shown, contact 322 is elongate, has a male compliant end 1802 for solderless mating with a corresponding through hole in a circuit board, and has a female end 1702 for receiving conical tip of signal contact 222. This is further illustrated in FIG. 20. FIG. 19 shows compliant (solderless) power contact 320 according to some embodiments.

[ 0024 ] Referring now to FIG. 20, FIG. 20 is a cross-sectional view of connector assembly 101 showing adapter assembly 104 mated with header assembly 102. As shown in FIG. 20, when assemblies 102 and 104 are mated, the adapaters of header assembly 102 are positioned within the cavity formed by housing 204 and the bottom faces of insulators 211/212, which cavity is best seen in FIG. 10, the signal contacts 222 engage with the signal contacts 322, thereby electrically coupling the signal contacts, and the contacts 220 engage with contacts 320.

[ 0025 ] In some embodiments header assembly 102 and adapter assembly 104 include means for facilitating alignment of the header assembly 102 with the adapter assembly when the two are blind mated. For example, one such means is the float plate 106 attached to adapter assembly 104. Float plate 106 has a through hole 107 for receiving a screw or pin (e.g., shoulder screw) (not shown) that is used to floatably connect adapter assembly to a chassis or other component. That is, adapter assembly 104 is preferably not rigidly connected to the chassis, but rather connected so that it has some radial and/or axial float relative to the chassis. Thus, when header assembly 102 is brought to adapter assembly and there is some small amount of misalignment, adapter assembly can move position relative to the chassis and relative to the header assembly 102 to thereby achieve alignment.

[ 0026 ] Other means for facilitating the correct alignment include: (a) an internal beveled edge 1002 (see FIG. 10) of adapter housing 204 and (b) beveled forward edges 1302, 1304 formed on walls 1306 and 1308, respectively. FIG. 21 shows housings 202 and 204 just prior to engagement and serves to illustrate how the beveled edge 1002 and beveled edges 1302, 1304 facilitate alignment. Still further means include the conical shaping of lead-in 1102 and the conical shaping of lead-in 1202. Additionally, through holes 614 are sized to allow contacts 222 to float slightly. Also, the signal contact through holes 2204 of signal insulator 312 have beveled edges 2206, as shown in FIG. 22. As further shown in FIG. 22, other means for facilitating the correct alignment include beveled edges 2201 and 2202 of insulators 311 and 312, respectively. [ 0027 ] Referring now to FIGs. 23-26, these figures illustrate a process for making connector system 100. The process begins by connecting an end of a wire (e.g., insulated wire) to a contact 222a and connecting the other end of the wire to signal contact 222b. This step is repeated as many times as necessary. After this step, contact 222b is inserted into signal insulator 212b and contact 222a is inserted into a signal insulator 212a as shown in FIG. 21. Again, this step may be repeated until there are no more empty though holes in the insulators. Next, insulators 212a,b are inserted into adapter housings 204a,b respectively, as shown in FIG. 23. Other insulators as needed may also be inserted into housings 204a,b. For example, one may insert into housings 204a,b, respectively, a first power insulator 211a and a second power insulator 21 lb, wherein, prior to insertion, insulator 21 la houses a power contact 220a that is electrically connected via a wire (or other means) to a power contact 220b housed in insulator 211b. Next, adapter assemblies 104a,b are mated with corresponding header assemblies 102a,b, respectively, such that the contacts of adapter assemblies 104a,b engage with corresponding contacts of header assemblies 102a,b, respectively (see FIG. 24).

[ 0028 ] The process of connecting plug 108 (see FIG. 1) to connector assembly 102b is similar. That is, for example, one end of a wire (e.g., wire 109) is attached to an end of a signal contact 222b and then the signal contact is inserted into an insulator through hole (e.g., hole 612 or 614). Preferably the step of inserting the contact in the through hole occurs prior to inserting in the adapter housing 204b the particular insulator in which the through hole is formed. The other end of the wire 109 may be connected to plug 108 or any other component.

[ 0029 ] Referring now to FIG. 27, FIG. 27 illustrates a connector system 2500 according to another embodiment. As shown, like connector system 100, connector system 2700 may include a first connector assembly 2701a electrically connected to a second connector assembly 2701b. Connector assembly 2701a may be substantially identical to connector assembly 2701b. Each connector assembly 2701 (i.e., connector assemblies 2701a,b) may include a header assembly 2702 and an adapter assembly 2704 (i.e., connector assembly 2701a may include header assembly 2702a and adapter assembly 2704a and connector assembly 2701b may include header assembly 2702b and adapter assembly 2704b). Each assembly 2701 may also include a float plate 2706 for connecting the adapter assembly 2704 to a chassis or other device.

[0030] Referring now to FIG. 28, FIG. 28 is a top view of an exemplary connector assembly 2701. As shown, header assembly 2702 of the connector assembly 2701 may include a header housing 202 and adapter assembly 2704 may also include an adapter housing 2804 for housmg various insulators (i.e., housings that house contacts and electrically insulate the contacts from one another). In the example shown, adapter housing 2804 is housing two power/RF insulators 211 and three signal insulators 212, the power/RF insulators 211 may house an RF contact 2820 and two signal contacts 222, and the signal insulator 212 may house a number of signal contacts 222 (e.g., eighteen signal contacts).

[0031] Referring now to FIG. 29, FIG. 29 is a bottom view of the exemplary connector assembly 2701. In the example shown, housing 2802 is housing two power/RF insulators 311 and three signal insulators 312, the power/RF insulators 311 are housing two power contacts 320 and two signal contacts 322, and the signal insulators 312 are housing a number of signal contacts 322. FIG. 30 is a side view of connector assembly 2701.

[0032] Referring now to FIG. 31 , FIG. 31 is a view of an exemplary adapter housing 2804. In the embodiment shown, housing 2804 is a generally rectangular housing open at opposite side thereof having two end walls and two side walls, and the side walls include grooves 502 for receiving a locking tab 602 (see FIG. 6) formed on a side wall of an insulator. The depth of the groove 502 decreases as the groove 502 proceeds inwardly, thereby forming a ramp structure. This facilitates the locking of an insulator in the adapter housing.

[0033] FIG. 32 is a top view of adapter assembly 2704 and shows an exemplary signal contact 222 inserted into a through hole 614 of signal insulator 212. FIG. 9 also shows an exemplary RF contact 2820 inserted into a through hole 611 of power/RF insulator 212. FIG. 33 is a bottom view of adapter assembly 2704 and shows that an end portion of RF contact 2820 and an end portion of signal contact 222 passes entirely through the through holes 611 and 614, respectively. That is the end portions of contacts 2820 and 222 extend beyond the bottom face of insulators 211 and 212, respectively. Insulators 211 and 212 and contacts 2820 and 222 configured like this so that the end portions of the contacts can mate with corresponding contacts of the header assembly 2702.

[ 0034 ] While in FIG. 32 adapter assembly 2704 is shown has having two power insulators 211 and three single signal insulators 212 arranged between the power insulators, the invention is not so limited. In fact, an advantage of adapter assembly 2704 is that it is extremely adaptable. That is, the type of insulators that may be housed in adapter housing 204 and the arrangement of said insulators in the housing is entirely up to the end user.

[ 0035 ] FIG. 34 illustrates an exemplary RF contact 2820, which, in the embodiment shown, includes a conical shaped lead-in 3402, which functions to facilitate alignment between assemblies 2702 and 2704. FIG. 35 is an exploded view of RF contact 2820 according to some embodiments. In the embodiment shown, RF contact 2820 includes: a clamp nut 3501 ; a crimp sleeve 3502; a dielectric (e.g., a Teflon dielectric) 3503; a signal contact 3504 and an outer body 3505. FIG. 36 is a cross- sectional view of the RF connector shown in FIGs. 34 and 35.

[ 0036 ] Referring now to FIG. 37, FIG. 37 illustrates an exemplary header assembly 2702. Like adapter assembly 2704, header assembly includes a header housing 2802 for housing power/RF insulators 311 and/or signal insulators 312. In the example, shown, because adapter assembly 2704 includes three signal insulators 212 sandwiched between two power insulators 211, header assembly 2702 also includes three signal insulators 312 sandwiched between two power insulators 311.

[ 0037 ] FIG. 38 further illustrates header housing 2802. Header housing 2802 includes a generally rectangular frame 3802 having two parallel end walls and two parallel side walls, and the side walls include grooves 1404 for receiving a locking tab (see e.g., element 602 in FIG. 6) formed on a side wall of an insulator. As also shown, housing 2802 includes two parallel side walls 3706, 3708 that face each other and extend outwardly from the end walls of fame 3802.

[ 0038 ] FIG. 39 illustrates RF contact 2920 according to some embodiments. As shown in FIG. 39, RF contact includes: a compliant member 3901; a dielectric 3902; a signal contact 3903; a outer contact 3904 and a n outer body 3905. [0039] In some embodiments header assembly 2702 and adapter assembly 2704 include features that facilitate alignment of the header assembly with the adapter assembly when the two are blind mated. For example, like float plate 106, float plate 2706 is attached to adapter assembly 2704 and is used to floatably connect adapter assembly to a chassis or other component. Other features that facilitate correct alignment include an internal beveled edge 3302 (see FIG. 33) of adapter housing 2804 and beveled forward edges 3702, 3704 formed on walls 3706 and 3708, respectively. Still further features include the conical shaping of lead-in 3402.

[0040] Referring now to FIG. 40, FIG. 40 illustrates a connector assembly 4001 according to another embodiment. As shown, like connector assembly 2701, connector assembly 4001 may include a header assembly 4002 and an adapter assembly 4004. In this embodiment, adapter assembly 4004 is also a header assembly because it is designed to connect directly to a printed circuit board, but to avoid confusion we shall refer to assembly 4004 as the adapter assembly 4004.

[0041] Connector assembly 4001 is almost identical to connector assembly 2701. For example, connector assembly 4001 includes: (a) an adapter housing 4094 for housing insulators 211 and 212 in the same manner that housing 2804 houses the insulators and (b) header housing 2802 for housing insulators 311 and 312. A difference between connector assembly 4001 and connector assembly 2701 is that different contacts are housed in the insulators. For example, as shown in FIG. 40, insulator 211 holds power contacts 4020, insulator 212 holds signal contacts 4022, insulator 311 holds power contacts 4021, and insulator 312 holds signal contacts 4023.

[ 0042 ] FIG. 41 further illustrates signal contacts 4022 and 4023. As shown in FIG. 41, contact 4022 is elongate and its tips 4103, 4104 are conical. Likewise, contact 4023 is elongate and has a conical tip 4101. The other end of contact 4023 (see element labeled 4102) defines an opening for receiving end 4103 of contact 4022. FIG. 42 further illustrates power contacts 4020 and 4021.

[0043 ] Referring now to FIG. 43, FIG. 43 illustrates a connector assembly 4301 according to another embodiment. As shown, like connector assembly 101, connector assembly 4301 may include header assembly 4002 and an adapter assembly 4304.

Adapter assembly 4304 is nearly identical to header assembly 2704. For example, adapter assembly 4304 includes adapter housing 4304 for housing insulators 211, 212. A difference between adapter assembly 4304 and adapter assembly 2704 is that adapter assembly includes different contacts than adapter assembly 2704. For example, as shown in FIG. 43, insulator 211 holds power contacts 4320, and insulator 212 holds signal contacts 4322.

[0044] FIG. 44 further illustrates signal contact 4322. As shown in FIG. 44, contact 4322 is elongate and has a conical tip 4401. The other end of contact 4322 (see element labeled 4402) defines an opening for receiving another contact (e.g., the end of a wire)

[0045] FIG. 45 shows exploded views of power contacts 4021 and 4320. As shown in FIG. 45, contact 4021 includes an dielectric 4502 for housing a contact 4501. Power contact 4320 includes: a contact element 4503; a rear body 4504; a front contact 4505; and a dielectric 4506.

[0046] While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not limitation. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments.
