Definitions
- the present invention relates to an electrical breakaway connector having improved release characteristics.
- Such an electrical connector is useful and almost mandatory in applications where emergency situations occur requiring immediate disconnection of the mating connectors with only a small tensile force place on the two cables which lead out of the connectors. It is also mandatory in these emergency situations that the two connectors do not become cocked or otherwise bound during disconnection which could hamper or prevent the disconnection between the two mated connectors.
- breakaway connectors having emergency disconnection requirements is in the aircraft pilot's helmet
- a breakaway connector is typically mounted to the base of the aircraft and a matable connector is connected to the pilot's helmet through data and power cable.
- the sophistication of the helmets has grown to require a multitude of signal and power contacts mounted within a small connection package, yet with the requirement that the mated connectors are easily disconnected.
- the breakaway aspect of the connector is critical in that during emergency ejection of the pilot, the connector must be released without undue binding of the two connectors.
- a further requirement of the breakaway connector is that the connector upstands vertically in the disconnected position such that the connector is always upwardly facing vertical and therefore the pilot need only use one hand to connect or disconnect the half to his or her helmet.
- This of course is an ergonomic consideration rather than a safety consideration, yet an important consideration when viewing the cramped quarters which are found in military aircraft. With one connector mounted to the base of the aircraft, undue burden and inconvenience would be placed upon the pilot to require him or her to reach over with the second hand to make the connection between the aircraft connector and the helmet connector.
- U.S. Patent 4,684,192 which includes an aircraft connector which is connectable to the base of the aircraft and a helmet connector half which is provided with the pilot's helmet.
- the aircraft connector is connected to the aircraft base by means of a lanyard making the aircraft connector movable relative to the base of the aircraft, yet it does not allow the connector to upstand in a given position for the ease of connection and disconnection.
- US Patent 4 533 796 which includes a ball and socket joint which is used as a rotatable connection for such cables as telephone cables which are typically umbilical in nature to expand and contract.
- the ball and socket joint is used to rotate the cable to ensure that the cord does not become entangled.
- the ball and socket joint is used in combination with spring loaded ball bearings in a race which allow the inner core to rotate thereby maintaining electrical continuity between inner and outer electrical terminals.
- the present invention consists, according to one aspect thereof, in a breakaway electrical connector for quick disconnection from a mating electrical connector along a disconnection axis
- the breakaway connector comprising a housing having secured therein electrical terminals for mating with electrical terminals of the mating connector and means for mounting the housing to a base so that the housing is movable with respect thereto; said mounting means including means to allow the breakaway connector to swivel, thereby aligning a longitudinal axis of the breakaway connector with said disconnection axis; characterized in that said swivel means includes means to resiliently bias the connector into a predetermined position.
- the means allowing the connector to swivel comprises a ball and socket joint, the ball including a detent, while the socket is spring loaded to bias the connector into said predetermined position.
- the mating face of the connector be upwardly facing relative to said base when the connector is in a disconnected condition.
- the mounting means may comprise a resilient annulus extending about the disconnection axis for urging the housing against the base.
- the resilient annulus may, in order to be self-damping, so that it oscillates as little as possible following a disconnection, be in the form of an elastomeric boot, or, if it is needed to operate under severe temperature cycling, in the form of a helical metal spring
- the resilient annulus is in the form of a helical metal spring enrobed in elastomeric material, so as to have self-damping properties.
- the housing may have a shoulder for engaging one side of the base and a stem, which may be in the form of a cable conduit, projecting from the shoulder and supporting the resilient annulus for engagement with the opposite side of the base, the stem passing through an opening in the base and supporting the resilient annulus, for example on a flange projecting from the base.
- the base is a pressure bulkhead
- the elastomeric boot or the elastomeric material enrobing the helical spring should be bonded both to the flange and to said opposite side of the base, in sealing tight relationship.
- the resilient annulus should be fixed both to the stem and to the base so that the breakaway connector cannot rotate about the disconnection axis.

- the swivel backshell further includes a rear cable clamp, such as 128, which defines a cable strain relief when a complementary clamp half 129 ( Figure 2) is installed onto the clamp block 128.
- a cable receiving through hole 130 extends through the swivel backshell for the receipt of the data and power cable therethrough.
- the swivel block 140 generally includes a flange 142 which is used for mounting the connector.
- the interior portion of the block 140 includes a complementary profiled surface 143 for surrounding the ball 124 of the swivel backshell 120.
- the swivel block 140 further includes a surface, such as 144, which circumferentially surrounds V-groove 126 of the swivel backshell 120.
- the swivel block further includes a plurality of threaded apertures, such as 146, which extend radially towards the center of the peripheral surface 144 to receive detent spring assemblies 150, having a threaded cap and a spring loaded ball, such as 152. It should be understood that when in use, two such swivel blocks 140 are used which are shell halves which interlockingly mate by means of alignment pins 147 and grooves 149.
- FIG. 15 and 15A An alternate detent spring assembly is shown in Figures 15 and 15A as 150′ which includes a ring 154′ having resilient fingers 156′ stamped out from the material which forms the ring.
- Four detent balls 152′ are included which cooperate with the fingers 156′.
- the terminals comprise the electrical connections, and include pins 160 and sockets 320 for the transmission of data signals, (Figure 11A); coaxial pins and sockets 190 and 330 for data transmission, (Figure 11B); and high voltage pins and sockets 310 and 220, (Figure 11C).
- the pin 160 comprises a pin portion 164, a crimpable portion 166 and a band portion 162 which is of a greater diameter than the crimpable portion thereby forming a forwardly and a rearwardly facing shoulder.
- Retention clip 170 is also shown as including a cylindrical portion 172 including integral retention fingers 174 which extend inwardly towards the center of the clip.
- Figure 11A also shows a socket 320 which is identical to socket 220, which will be described herein; and a retention clip 328, identical to clip 170.
- coaxial pin 190 is shown as including an outer conductive housing including a forward shroud portion 200, a central constricted portion 196, a bulged or contracted portion 198, and a rear end portion 202.
- a retention clip 206 having fingers 208, is snapped into and around the constricted portion 196.
- Reference to Figure 16 shows that the interior of the coaxial terminal 190 includes a pin section 192, having a crimpable portion 194, the pin portion 192 and the crimpable portion 194 being insulated from the exterior housing member.

- Coaxial socket 330 further includes an identical retention clip as retention clip 206.
- the interior of the coaxial socket includes a tube 339 which is matable with a coaxial lead at the rear end and which is matable with the coaxial pin 192 at its opposite end.
- FIG. 11C shows the high voltage assembly as including the insert 90, a socket 220, a retention clip 112 and a retention collar 110.
- Socket 220 is identical to socket 320 and includes a crimpable portion 222, a socket portion 224, and a central band portion 226.
- the interior of the collar ( Figure 13A) includes a shoulder 113 which is smaller than the diameter of the retention clip 112.
- Pin 310 is identical to pin 160 which was described above.
- the cable is first inserted through the opening 130 in the swivel block, and then the individual conductors are terminated to their respective terminals.
- the data conductors 236 can be terminated to the crimpable portions 166 of the terminals 160 ( Figure 11A); the coaxial conductors 234 are terminated to the crimpable portions 194 ( Figure 13); and the high voltage terminals are prepared by placing the conductor of the cables 238 within the crimpable ends 222 and the conductors crimped in place.
- the connector housing is preassembled by placing the forward insert 30 within the metallic shell 4, placing the retaining clips within the apertures 40, and then assembling the rear insert 60 in place within the metallic shell 4, and locked in place within the shell 4 via the snap ring 230.
- the retention clips 170 remain within the apertures 40 as the diameters of the apertures 66 in the rear insert 60 are smaller than the diameters of the retention clips 170.
- the retention clips 170 are sandwiched between the forward 30 and rear 60 inserts, the high voltage inserts 60 are sandwiched between the inserts 30 and 60 also.
- the terminals 160 are then insertable through the respective apertures 60 and 40, and snapped into the position shown in Figure 13.
- the high voltage terminals 220 are retained within the high voltage inserts 90 via the retention clips 112 and the collars, and the retention clips 112 and the collars can either be preassembled within the high voltage inserts 90 prior to the assembly of the inserts 90 between the inserts 30, 60, or can advantageously be assembled after their assembly. In either event, the retention clip 112 and the retention collar 110 are slid forwardly into the high voltage inserts 90 until the front ends of the collars 110 abut the shoulders 98 within the high voltage inserts 90 ( Figures 8 and 13A).
- the collars 110 are frictionally fit within the bores 96 and a tool (not shown) can include a split seam which is receivable over the conductors 238 to apply a force to the rear of the collars 110, which in turn carries the retention clips into the inserts 90.
- the terminals are then insertable from the rear of the connector and are spring clipped in place, as shown in Figure 13A.
- the coaxial pins 190 are retained within their respective apertures by means of retainers 206 which are snapped over the diameter of the coaxial pins 190.
- the coaxial pins 190 and their retainers 206 are receivable into the assembled inserts 30, 60 to the retained position shown in Figure 16.
- a snap ring 230 is placed in the shell 4 within the groove 22 which retains the two inserts 30, 60 in place. It is preferred that the rear of the insert 90 be potted with an appropriate sealing compound to prevent discharge/sparking from the rear of the high voltage terminals.
- the swivel backshell 120 is threaded to the rear of the shell 4 and the two swivel blocks 140 are attached in a surrounding relation with the swivel ball 124.
- the connector 2 can then be mounted to the base of an aircraft for use with a connector attached to a pilot's helmet.
- each detent assembly is simply inserted into an associated threaded aperture 146, and screwed into the aperture 146 until the ball 152 resides within the V-groove 126 of the swivel block 120.
- the connector 2 is matable with a similar connector 250 shown in Figure 12 which includes polarizing bar 302 which is complementary with the notch 8 in the outer shell 4, and further includes detents 304 which are complementary with the rollers 21 and spring pins 20 in the outer housing 4.
- the connector 300 includes associated apertures 306 for receipt of the high voltage inserts while the pins 320 and 330 extend forwardly from the connector 300 for insertion into the respective apertures within the connector 2.
- the above described connector solves the problems found in previous, prior art connectors as the connector is allowed to swivel relative to the aircraft and the connector is retained in a semi-rigid position when not in use making it easy for the pilot to connect the two mating connectors with the use of only one hand.
- the connector 2 is shown in the free state without exterior forces on the connector causing the connector to swivel.
- a force causes the connector to swivel, for example if the pilot is ejected, the ball and socket joint will allow the connector to swivel, as shown in phantom in Figure 15.
- the spring detents 150 or 150′ within the V-groove 126 will be spring loaded against the V-groove thereby forcing the connector to return to an upstanding condition, where the detent balls will reside within the center of the V-groove. It should be appreciated that by allowing the connector 2 to swivel, when an axial or tensile force is placed on the connector 300, the instant invention prevents any locking or jamming of the two mated connectors during their disconnection. Furthermore, by allowing the connector 2 to return to its upright position when no force is placed upon the two connectors, the pilot can install the connector 300 to the connector 2 with only one hand as the connector will always be facing upwards towards him or her.
- a second embodiment of a breakaway electrical connector 401 comprises a housing in the form of a forward, metallic, circular cross section, shell 400 having therein a forward dielectric insert 402 and a rear dielectric insert 404 secured in the housing 400 by means of a snap ring 406.
- the inserts 402 and 404 cooperate in turn to secure, electrical terminals 408 in the shell 400 these being data terminals.
- high voltage power terminal inserts 410 and carrying high voltage electrical power terminals 412 are secured in the inserts 402 and 404, high voltage power terminal inserts 410 and carrying high voltage electrical power terminals 412, the terminals 408 and 412 being crimped to electrical leads L1.
- the shell 400 has a forward shroud 414 formed with a keying or polarizing notch 418, and rearwardly of the shroud 414 pairs of blocks 420, on diametrically opposite sides of the shell 400 each supporting a spring pin 422 on which is a roller 424 projecting into the shell 400.
- the shell 400 is formed with an external peripheral screw thread 428.
- the breakaway connector 401 further comprises a cable conduit 428, which like the shell 400 is of circular cross section and is made of metal.
- the conduit 428 has a mount part 430 and a stem 431 comprising a frusto-conical transition part 432 which tapers away from the part 430 and, extending from the smaller end of the part 432, a cable lead out part 434.
- the parts 430 and 432 cooperating to define an annular shoulder 436 which faces away from the shell 400.
- the conduit 428 is coupled to the shell 400 by means of an internally screw threaded ring 438 having finger grips 440 ( Figure 20), the ring 438 meshing with the screw thread 426 of the shell 400 and having an annular rearward flange 440 engaging an annular forward flange 442 of the mouth part 430 to secure the conduit 428 to the shall 400, when the right 438 has been screwed home.
- the cable lead out part 434 has fitted thereabout and spaced substantially rearwardly of the transition part 432, an annular support flange 444 secured tightly between a smaller annular flange 446 formed integrally with the part 434 and a removable pin 448 passed through opposed openings in the cable lead out part 434.
- the connector 401 further comprises a resilient annulus in the form of an elastomeric boot 450 having a generally rectangular, annular rear connecting part 452 bonded into a complementary recess 454 in the flange 444, and a forward annular, generally rectangular, connecting part 456.
- the boot 450 has peripheral annular corrugations 457. As indicated in broken lines in Figures 20 to 22, the leads L1 extending from the terminals 408 and 412 are enclosed in a cable jacket J passing through the cable conduit 428.
- the breakaway connector 401 is assembled to a base B, which is shown in fragmentary from in Figures 20 to 23, with the flange 444, and thus the boot 450, removed, and the cable conduit 428 secured to the shell 400 by means of the ring 438.
- the cable lead out part 434 is inserted through an opening O in the base B which is, in the present example, the floor of an aircraft fight deck or a vertical pressure bulkhead bounding the flight deck; until the annular shoulder 436 in the opening O which must be dimensioned so that there is clearance between said forward portion and the edge of the opening O.
- the flange 444 is then threaded on to the part 434 so as to abut the flange 446 and the pin 448 is then pushed through the openings in the part 434 to secure the flange 444 in position.
- the part 456 is then bonded to the opposite side of the base B, that is to say its lower side as seen in Figures 20 to 23.
- a mating electrical connector 460 for the breakaway connector 401 comprises, as shown in the Figures 17 to 19, a housing in the form of a metal shell 462 having a forward shroud 464 for reception in the shroud 414 of the shell 400 and being formed with opposite detents 466 (only one of which is shown) for cooperation with the rollers 424 to retain the connectors 401 and 460 in mating relationship.
- the shell 462 Spaced back from the shroud 464, the shell 462 is formed with a keying or polarizing bar 468 which is complementary with the notch 418 in the shroud 414, so that the connectors can only be mated in their correct relative angular positions.
- dielectric inserts 470 and 472 Secured in the shell 462, are dielectric inserts 470 and 472 in which are in turn secured, electrical data terminals 474 for mating with the terminals 408 in the shell 400.
- high voltage terminal inserts 476 carrying terminals 477 for mating with the terminals 412 in the housing 400.
- the terminals of the connector 460 are crimped to leads L2 which extend through a frusto-conical rear end cap 476 releasably secured to the shell 462, into a cable jacket J2 which extends rearwardly from the cap 476 and to which is attached a lanyard LA which is connected to the harness of the pilot of the aircraft.
- the leads L2 extend to the pilots helmet for the supply to power and data to electrical equipment therein.
- Figure 18 shows the breakaway connector 401 and the mating connector 460 in partially mated relationship with the bar 468 on the shell 462 about to enter the groove 418 of the shroud 414, whilst Figure 19 shows the connectors 401 and 460 in their fully mated position in which the bar 468 is received in the groove 418 and the rollers 424 are engaged in the detents 466.
- the shell 462 of the mating connector 460 is, in the fully mated condition of the connector 401 and 460, deeply engaged in the shell 400 of the breakaway connector 401 and is releasably locked thereto by means of the rollers 424 and detents 466.
- the connectors 401 and 460 can only be mated and disconnected, therefore, along a particular mating and disconnection axis A - A which is in fact the central longitudinal axis of the two connectors.
- Figure 21 shows the housing 400 a position in which it is aligned by means of the resilient annular 450 so that it extends normally of the base B with the shoulder 436 resting thereon in full surface to surface contact therewith.
- the pilot can readily and with one hand, mate the connector 460 with the connector 401 along the axis A - A, since the pilot will be aware of the exact angular position of the breakaway connector 401. Should the pilot eject tensile force will be exerted upon the connector 460, since the lanyard LA is attached to the pilot's harness, this tensile force having a substantial lateral component.
- the breakaway connector will be tilted laterally, in the sense shown, for example, in Figure 22, about the shoulder 438 which cooperates with the base B to provide what is in effect, a hinge, so that the breakaway connector 401 swivels with respect to the base B so as to align it with the axis A - A.
- the connector 460 readily disconnects from the breakaway connector 401 without impeding the ejection of the pilot, the annulus 450 acting to some extent as a shock absorber.
- the clearance between the part 432 and the edge of the opening O in the base B is preferably such that the breakaway connector can tilt through 60°, that is to say through 30° in any direction. Since the annulus 450 is bonded both to the flange 444 and to the base B, the breakaway connector cannot rotate about its own axis whereby any winding up of the pilot's harness is avoided. Also, when the connectors 401 and 460 are to be mated, the groove 418 is always oriented in the same angular position about the axis A - A, which also facilitates ready mating of the connectors by the pilot.
- a metal spring 480 should be enrobed in the annulus 450 where the breakaway connector 401 is to be subjected to severe changes in temperature, since the performance of a metal spring is less likely to be affected thereby than that of an elastomeric material.
- the annulus 450 could be omitted and a resilient annulus in the form of the helical spring 480 be arranged to act between the flange 444 and the base B, preferably being fixed to both of these.
