  • the seal 34 is made of a noncompressible material such as a silicon rubber, when the pressure plate 38 is forced against the seal 34 it causes the material in the seal to flow radially in all directions. It flows against the passage 24 and the conductors, etc. This in turn insures an intimate, high pressure contact against all of the surfaces whereby a high degree of sealing is insured.
  • cable 12 normally includes an electrically conductive outer jacket 42 which acts as the shielding for the cable 12. It is essential that the shielding on each of the cables be electrically connected through the connector to the other cable.

This is effective to provide a high degree of shielding against electromagnetic interface. However, it has been found that under some circumstances and particularly at the higher frequencies it may be desirable to provide a higher or more complete degree of shielding.
  • a sleeve or liner 50 is provided inside of the receptacle section 16.
  • the liner 50 fits snugly in the passage 24 through the shell 20 and the inserts 28 and 30 fit snugly inside of the liner 50.

  • the individual wire or conductors in the second cable 14 extend through the openings in the rear insert 68 and are connected to the contacts 70; It can thus be seen that by joining the two sections '16 and 18 all of the individual wires in each of the cables 12 and 14 are electrically interconnected with the respective individual wires in the other cable.
  • the rear of the plug section 18 includes a resilient seal 72 similar to the seal 34 in the receptacle section 18.
  • a pressure plate 74 is also provided for tightly compressing the seal 34 against the wires, etc., to keep out dust, dirt, moisture, etc.
  • a nut 76 is threaded onto the exterior of the shell 54 and forces the pressure plate 74 against the seal 34.
  • this includes a thin wafer 78 of an elastomeric material such as silicone rubber, etc.
  • the wafer 78 includes a large number of small openings which register with the openings in the inserts 28, 30, 66 and 68 to allow the pins 71 to extend therethrough. It has been found desirable for the pins 71 to be a snug fit in these openings whereby the wafer 78 will normally remain on the face of the plug section 18. When the two sections 16 and 18 are fully mated, the thin wafer 78 is compressed between the faces of the two inserts 26 and 66. As a result the elastomeric material in the wafer 78 tends to flow into and against all of the surfaces and thereby provides a complete and effective sealing action.
  • the plug section 18 includes an electrical grounding or shielding generally similar to that in the receptacle section 16. More particularly, an inner sleeve or liner 80 is provided in the inner portion 62 of the passage 56.
  • the liner 80 includes a radial flange 82 which fits over and around the end of the insert 66. The rear of the liner 80 fits over the end of the shell 54 and is clamped in position by the nut 76. This prevents the inserts 66 and 68, etc., from sliding forwardly through the shell 54.
  • a back shell 84 is provided on the rear of the shell 54. This may be identical to the back shell 44 on section 16. However, in this embodiment it is somewhat different.

  • a resilient metal rim or ring 90 encompasses the periphery of the resilient wafer 78.
  • the ring 78 is a highly conductive metal and has a U-shaped cross section which fits over the opposite sides of the periphery of the wafer 78. This tends to clamp the periphery of wafer 78therebetween.
  • the flanges 52 and 82 on the ends of the two liners 50 engage the metal rim or ring and compress it therebetween. It has been found desirable to out several slots 92 into one or both sides of the rim 90 and thereby form a plurality of resilient fingers 94. These fingers 94 permit the rim 90 to be compressed between the flanges 52 and 82 on the ends of the liner sleeves 50 and 80.
  • the elastomer in the thin wafer seal 78 is, in reality, incompressible. As a result when the wafer seal 78 is compressed between the faces of the inserts 28 and 66, it tends to flow radially outwardly toward the interior of the rim 90. However, since the rim 90 fits snugly onto the periphery of the waver 78 this tendency to flow radially outwardly is opposed by the axial compression of the rim 90. This assists in insuring that the axial forces compressing the rim and the axial forces compressing the wafer seal 78 provide a highly effective sealing action and a highly effective electrical connection.

  • the portion of the plug section 18 described so far will mate properly with receptacle section 16 and provide an effective electrical interconnection between the two cables 12 and 14. However, it is preferable to provide additional means to facilitate the mating of the two sections and/or to insure their remaining securely locked together.
  • a so-called breech lock 102 is provided for securing the two sections together.
  • the lock 102 includes a nut or outer sleeve 104 rotatably disposed around the outside of the shell 54.
  • the end of the sleeve 104 projects beyond the end of the shell 54 and includes a flange 106 that projects radially inwardly.
  • the flange 106 forms an opening 108 which is just barely large enough to allow the barrel 23 to pass therethrough.
  • the interior of the sleeve 104 is undercut immediately behind the flange 106 to form an annular channel 110 and a radial shoulder 112.
  • a plurality of key-ways 114 is cut through the flange 106. These key-ways 114 are aligned with the key-ways 100 cut into the surface of the passage 56 and/or to register with the keys 98 projecting from the barrel 23 on the receptacle shell 20.
  • the plug section 18 is fitted over the barrel 23 of the receptacle section 16 and moved axially toward the bulkhead 22.
  • the flange 106 on the end of the sleeve 104 abuts the mounting flange 21.
  • the sleeve 104 is then rotated until the shoulder 112 moves behind the ends of the projections or keys 98. This requires a small fraction of a turn, for example, approximately /a of a rotation.
  • the shoulder 112 and the ends of the keys 98 are all in a common radial plane. Accordingly, the movement of the shoulder 112 behind the keys 98 does not produce an axial force or movement. In other words, the beech lock 102 does not tend to screw the two sections 16 and 18 together. Instead, it merely locks them together. Conversely, to release or unmate the two sections the sleeve 104 is merely rotated until the shoulder 112 is no longer behind the keys 98.
  • the keys 98 and the key-ways 100 may be arranged such that the mating surfaces have extended circumferential lengths. Because of this extended length of the mating surfaces, even a relatively small height on the shoulder 112 and the keys 98 insures a very large area of contact for the breech lock. This large contact area insures a very low stress between the mating surfaces. This in turn insures a lock which is easy to manually work and which does not wear, etc.
  • this breech lock 102 provides a very simple and fast-mating action. It also provides a very large bearing area to carry the load and reduce the stress into a workable range. Although the breech lock 102 is effective to allow the two sections contacts 32 and within the connector are placed in proper electrical engagement and maintained in full electrical engagement at all times.
  • the threads 116 and 118 preferably have a very high pitch; i.e., the amount of axial movement is very large for a small amount of rotation.
  • the pitch of the threads 116 and 118 should be large enough to move the shell 54 between the fully retracted position and the fully extended position when the sleeve is rotated through a small fraction of a turn. Normally this is about the smallest amount of rotation required to operate the breech lock 102.
  • the pin contacts 70 are retracted and prevented from hitting the end of the barrel 23, etc.
  • the two sections 16 and 18 are usually skew or otherwise misaligned. If the pins 70 are engaged under such conditions, they will be damaged by bending, etc. If the contacts are kept separated until after the end of the two sections 16 and 18 are sufficiently mated to insure a very accurate axial alignment, they will not be damaged and will mate properly.
  • the sleeve 104 is rotated whereby the breech lock 102 is fully secured. During this rotation of the sleeve 104 the threads 116 and 118 advance the shell 54 forward toward the shell 20. The distance of this travel is sufficient to fully mate the pin contacts 70 with the socket contacts 32 and compress the wafer seal 78 between the two faces of the inserts 28 and 66.
  • a spring 120 may be provided inside of the sleeve 104 to assist in locking the connector and retaining it locked.
  • the spring 120 is trapped between a collar 122 on the inside of the sleeve 104 and a shoulder on the shell 54. This spring 120 exerts an axial force on the shell 54 and biases it toward the shell 20.
  • the combination of the thrust from the spring 120 and the high pitch of the threads 116 and 118 insures the two sections 16 and 18 and the electrical contacts 32 and 70 always being completely locked together. I
  • the combination of the high pitch of the threads 116 and 118 and the axial force from the spring 120 results in a torque being created.
  • This torque tends to rotate the sleeve 102 about the shell 54.

  • the force from the spring 120 also assists in maintaining all of the contacts fully engaged.
  • the torque biases all of the parts together.
  • the spring applies a torque that keeps the breech lock 102 in the fully locked position.
  • an adequate torque can be maintained to eliminate the necessity for using a keeper wire, etc., for securing the sections together.
  • the breech lock 102 is effective to fully secure the two sections 16 and 18 together. Therefore, even though the spring 120 provides a resilient biasing action and even though there is some play between the threads 116 and 118, there is no mechanical play, etc., in this lock 102.
  • the biasing action of the spring 120 merely parallels the fastening action of the breech lock 102 and does not provide any resilience in the locking action. Accordingly, before an accident can pull the sections 16 and 18 apart, it is necessary to destroy the lock 102. Therefore, even in the event of any abnormal forces, i.e., vibration, impact, etc., the sections 16 and 18 and all of the electrical contacts 32 and 70 will be retained completely locked together.
  • the foregoing spring 120 exerts an axial load on the threads 116 and 118 whereby a torque is created on the sleeve 104.
  • a torsion spring may be employed for creating a torque between the sleeve 104 and the shell 54. This in turn creates the same type of sealing action, etc., previously described.

  • both ends of the spring 122 move at essentially the same rate and the torsion on the spring 122 is essentially constant.
  • the slope of the cam surface 132 varies. This variation in the slope causes the spring 122 to produce a much larger torque which biases the shells 20 and 54 and contacts 32 and together. Moreover, it causes the spring 122 to continually exert a large torque which retains the two sections of the connector fully mated.
  • the combination of the cam surface 132 and torsion spring 122 can be effective to greatly reduce the amount of travel of the spring 122. This in turn reduces the weight, size, etc., of the spring 122. Also, the forces imposed by the spring 122 may be reduced.

  • a lock 160 is provided for securing the two sections 16 and 134 together.
  • the lock 160 includes a retainer 162.
  • the retainer 162 has a generally cylindrical section 164 which is slidably disposed upon the exterior of the shell 136.
  • a plurality of resilient fingers 166 are formed on the retainer 162 and project axially along the shell 136. The end of each finger 166 includes an enlargement 168.
  • Each of the enlargements 168 is tapered to mate with the ridge 95.
  • the end of the shell 136 slides axially along the exterior of the shell 20.
  • the keys 98 pass through the key-ways 144 and the enlargements 168 ride up and over the ridge 95.
  • the enlargements 160 have passed over the ridge 95 and have dropped down into the annular channel or recess 96 and engage the annular shoulder 97 on the inside of the ridge 95.
  • a collet ring 170 is slidably disposed on the outside of the shell 136. It includes an annular shoulder 172 on the inside thereof. When the shell 136 is fully retracted, it engages. the shoulder 172 and retains the collet ring 170 retracted.
  • the collet ring 170 When the shell 136 is extended, the collet ring 170 is also allowed to move into the extended position. As it moves toward the extended position, it passes over the outside of the enlargements 168 and completely surrounds them. The inside of the collet ring 170 is a snug fit on the outside of the enlargements 168.
  • the plug section 134 is first brought into the axially aligned position shown in FIG. 10.
  • the key-ways 144 on the plug section 134 are then aligned with the keys 98 on the receptacle section 16.
  • the plug section 134 is then forced axially onto the receptacle section 16. During this axial movement, the end of the shell 136 slides over the barrel 23 and the enlargements 168 on the ends of the fingers 166 ride up and over the ridge 95 and down into the annular channel or recess 96.
  • the sleeve 154 is then rotated whereby the shell 136 is advanced axially through the sleeve 154. This motion causes the contacts 32 and 152 to mate, etc. It also causes the collet ring 170 to slide over the outside of the enlargements 168 on the ends of the fingers 166. Since the collet ring170 fits snugly around the fingers 166, the enlargements 168 cannot expand outwardly and are securely locked onto the end of the barrel 23.
  • a spring 174 is trapped between the retainer 162 and the collet ring 170. It then produces an axial thrust which tends to advance the shell 136 into the extended position. As a result it assists the operator in turning the sleeve 154 and locks the two sections together.
  • the sleeve 154 may be rotated in the opposite direction.
  • a device such as a lanyard 176 may be secured to the collet ring 170.
  • the collet ring 170 is moved to its retracted position.
  • the enlargements 168 are thus freed whereby they can ride over the ridge 95.
  • the two sections 16 and 134 can be separated without ever rotating the sleeve 154.
