  • An O-ring 117 is mounted in a groove in an intermediate section of the outer conductor body 116.
  • a flat plate 120 provides a common mounting structure for the equipment connectors 110. As can be seen in FIG. 7, the plate 120 includes four aligned holes 121, each of which is encircled by a recess 122 on its rear side.
  • the recesses 122 are contiguous with each other.

  • the free end of the outer conductor body 156 does not reach the plate 120, thereby forming a gap g4 therebetween.
  • the presence of the gaps g3, g4 enable the connectors 150 of the cable connector assembly 140 to shift axially relative to their corresponding mating connectors 110 in the event such shifting is required for mating (e.g., because of manufacturing tolerances and the like).
  • the presence of the gaps gl, g2 between the outer conductor bodies 156 and the shell 160 enables the connectors 150 to shift radially relative to the connectors 110 in the event such shifting is required.
  • the configuration enables the mated connectors 110, 150 to be closely spaced (thereby saving space for the overall connector assembly 100) without sacrificing electrical performance.
  • the illustrated assembly 100 depicts connectors 110, 150 that satisfy the specifications of a“2.2/5” connector, and may be particularly suitable for such connectors, as they typically are small and are employed in tight spaces.
  • FIGS. 16-21 another embodiment of an assembly of mated ganged connectors, designated broadly at 200, is illustrated therein.
  • the assembly 200 is similar to the assembly 100 in that an equipment connector assembly 205 with four connectors 210 mates with a cable connector assembly 240 with four connectors 250.

  • the housings 324, 352 of the connector assemblies 305, 340 include upper portions that are rounded slightly (as compared to the lower portions, which are generally straight). This difference serves as an orientation feature to ensure that the assemblies 305, 340 are properly oriented relative to each other for mating, which further ensures that the connectors 310, 350 are each aligned to mate with the correct mating connector.

  • the resilience of the material biases the individual connectors toward their“centered” position to more easily align with their respective mating connectors 405. This effect can also help to center the entire cable connector assembly 440, as the centering of two of the connectors of the cable connector assembly 440 can help to center the whole assembly 440.

  • the fm 1058 is swaged or otherwise formed into a truncated conical configuration (shown at 1058’ in FIG. 40).
  • the inner diameter of the fin 1058’ is then cut from the remainder of the outer conductor body 1056 (see FIG. 41). In this configuration, the fin 1058’ can serve as a spring that allows axial adjustment of the outer conductor body 1056.
  • the process described above can provide a Belleville washer-type spring that may be more suitable than a separate washer, as the inner diameter of the fm 1058’ (which can be an important dimension for achieving a desirable spring action) can be closely matched to the outer diameter of the outer conductor body 1056.
  • FIGS. 42A-42C and 43A-43C another assembly, designated broadly at 1100’, is shown therein.
  • axial float is provided with a spring 1180’ similar to that shown for the assembly 1100.
  • radial float is controlled differently by the ID and OD of the outer connector bodies 1116’, 1154’ at the interface and the OD of the rear end of the outer connector body 1154’ and a ramped transition surface 1155’.
  • the connector 1150’ in an unmated condition, the connector 1150’ is able to float axially and radially due to the spring 1180’.
  • the spring 1180 in the mated condition of FIGS.
  • mating of the outer connector bodies 1116’, 1154’ tends to radially align the connector 1150’, and as it floats rearwardly, the ramped transition surface 1155’ forces the rear end of the outer connector body 1154 into radial alignment. As this occurs, though, there is still the opportunity for axial float at the outer connector body 1154’ moves rearwardly.
  • the clearance at both ends of the outer conductor body 1154’ is sufficiently minimal that this interaction can be used to maintain the mated condition without other external means. (In fact, those skilled in this art will recognize that this concept may be employed with a single connector pair and is not limited to ganged connectors as illustrated herein). Also, as noted above, in some embodiments the spring 1180’ may be omitted, as the resilience of the shell 1160’ may provide sufficient give to permit any needed axial float.
  • annular insert 1270 is shown therein.
  • the insert 1270 is discontinuous, having a gap 1271 in the main wall 1273.
  • Four blocks 1274 with arcuate external surfaces 1275 extend radially outwardly from the main wall 1273.
  • Snap projections 1276 extend radially outwardly from the main wall 1273 between each pair of adjacent blocks 1274.
  • Construction of the assembly 1240 can be understood by reference to FIGS. 47, 49-51, 53 and 54.
  • a terminated cable 1242 with a connector 1250 attached to the end thereof is inserted through the central cavity 1266.
  • the cable 1242 is then forced radially outwardly through one of the gaps 1264 and into the corresponding peripheral cavity 1267, with the tower 1263 being sufficiently flexible to deflect to allow the cable 1240 to pass through the gap 1264.
  • the connector 1250 is located relative to the shell 1260 so that rear end of the outer body 1252 of the connector 1250 fits within the recess 1265 and is captured by the lip 1265a (see FIGS. 53 and 54). This process is repeated three more times until all four of the peripheral cavities 1267 are filled (see FIG. 47, which shows two cables 1240 in place in the shell 1260).
  • a fifth terminated cable 1242 is passed through the central cavity 1266 and the connector 1250 is located relative to the shell 1260.
  • the insert 1270 is slipped over the cable 1242 (i.e., the cable 1242 passes through the gap 1271 in the insert 1270) and oriented so that the blocks 1274 fit between the transition walls 1269.
  • the insert 1270 is then slid along the cable 1242 and into the central cavity 1266 (see FIG. 49) until the snap projections 1276 snap into the indentations 1265. This interaction locks the final (central) cable 1242 into place.
  • the cable connector assembly 1240 can then be mated with the equipment connector assembly 1205 as shown in FIG. 52.
  • cables may be arranged in this manner in a smaller footprint than similar cables arranged in a circular pattern.
  • the assembly 1240 may be formed with four cables 1242 (one each residing in the peripheral cavities 1267), with the central cavity 1266 being filled with a circular (rather than annular) insert.
  • an assembly 1400 comprises an equipment connector assembly 1405 and a cable connector assembly 1440 that provides sealing via one O-ring 1480 positioned like the O-ring 1380 and a second O-ring 1485 positioned between the outer conductor body 1456 and the shell 1460.
  • the O-rings are positioned such that they can provide two separate seals between the assemblies to ensure the prevention of water egress into the area of electrical contact between the outer conductor bodies of the connectors.
  • an assembly 1500 is similar to assembly 1400, but includes a molded-in sealing protrusion 1590 that is part of the shell 1560 rather than the O- ring 1485.
  • the shell 1460 of the cable connector assembly 1440 shown in FIG. 58 has cavities 1467 with sections 1468 that are generally hexagonally- shaped, but that have beveled corners 1468a between the sides 1468b of the“hexagon.” Put another way, the sections 1468 are 12-sided, with six long sides 1468b and six shorter sides 1468a. As shown in FIGS. 60 and 61, this arrangement can prevent the connectors 1450 from over-rotating within the cavity 1467 (which can damage the cable and/or produce debris that can negatively impact performance) while still permitting same degree of radial float.
  • FIGS. 62-64 As another example of addressing the desire for some radial float of the connectors while limiting twist, a connector assembly 1600 is shown in FIGS. 62-64.
  • the connector 1650 of the cable connector assembly 1640 has teeth 1669 on the outer conductor body 1654, and the shell 1660 has corresponding recesses 1670 (in the embodiment shown herein, the connector 1650 has six teeth 1669, and the shell 1660 has six recesses 1670, although more or fewer teeth/recesses may be included).
  • This arrangement also reduces the degree of twist between the connector 1650 and the shell 1660, which can protect the cable and prevent the production of undesirable debris, but also permits some degree of radial float.
  • fastening features may include the numerous latches, screws and coupling nuts discussed above, but alternatively fastening features may include bolts and nuts, press-fits, detents, bayonet-style“quick-lock” mechanisms and the like.
