Definitions
- ABSTRACT The following specification discloses a coupling assembly for electrical connector apparatus in which a threaded coupling ring rotatably mounted on one shell is threaded onto a second shell to couple the shells for electrically engaging the contacts carried by the shells.
- Each tooth on the flange has a cam face formed at a small angle to the radial plane of the flange for engagement with a similar cam face on each tooth on the ratchet washer in response to the threading rotation of the ring to cam the ratchet washer from the flange against the spring bias so that resistance to threading rotation is minimized.
- a stop face having a large angle to the respective radial planes of the washer and flange is also formed on each tooth and the stop faces engage for providing a large resistance to rotation of the coupling ring in the unthreading or loosening direction to prevent inadvertent loosening, but do permit rotation in the loosening direction, if disassembly is desired.
- Electrical connector apparatus usually includes a plug shell carrying a plurality of contacts each engageable with a respective contact of a plurality of contacts carried by a receptacle shell.
- a coupling ring rotatably mounted on one shell may be arranged for threaded engagement with the other shell to move the shells axially of each other and ensure electrical engagement between the respective contacts.
- a flange on the one shell has a front radial face abutting an internal shoulder of the coupling ring and a rear radial face on the flange engages a wave washer captured between the flange and a retaining ring secured to the rear end of the coupling ring.
- The" rings are thus capable of limited axial movement relative the one shell against the bias of the wave washer to permit the coupling ring to be threaded on the other shell.
- the biasing force of the spring wave washer acting in an axial direction provides a force for holding the threads engaged; however, this force is of substantially the same magnitude as the force required to thread the coupling ring on the other shell. Occasionally vibrational or other forces, having a magnitude corresponding to the force holding the threads engaged, are applied to the shells and therefore loosen the coupling ring from the other shell.
- Arrangements for resisting loosening or unthreading forces between connector shells have incorporated axially extending smoothly curved contoured teeth fixed on a coupling ring and engaging similarly contoured fixed teeth on one connector shell with the ring and its teeth biased toward the mating shell.
- both the coupling ring and the mating shell must reciprocate axially to permit the rotation and therefore considerable force is required.
- the smooth contour provides no greater resistance to rotation of the ring in the loosening direction than for tightening.
- teeth having faces which are perpendicular to each direction of rotation have been employed, but these must be disengaged to permit threading, and after the threading operation is completed, the perpendicular faces on the teeth are re-engaged to prevent loosening. Disassembly is permitted on retraction or disengagement of the engaged perpendicular faces of the teeth from one another against a spring bias. As may be visualized, this arrangement, while it holds the members against loosening and also permits disassembly, is relatively expensive, cumbersome and difficult to operate, since the teeth must be held disengaged while the ring is either tightened or loosened. Other arrangements may incorporate spring detents.
- Such detents can deform to move past a set of teeth in response to the threading rotation, but disassembly cannot be provided without auxiliary means for disengaging the detents from the teeth.
- springs used in electrical connector coupling assemblies require considerable wall thickness and sturdy construction in order to provide the desired spring force and therefore cannot be easily fabricated to provide reliable and durable opera tion or enable facile disengagement in the event disassembly is desired.
- the present invention avoids the above problems through the simple provision of a ratchet washer keyed to the coupling ring and interposed between the conventional wave washer and the flange on one connector shell.
- the ratcher washer has axially extending ratchet teeth for nesting engagement between axially extending pawl teeth on the one shell flange with each tooth having a leading or cam face formed at a small angle to a radial plane for enabling facile threading of the coupling ring against the force of the wave washer and a stop face formed at a steep or large angle to the radial plane for strongly resisting rotation in the opposite or unthreading direction.
- Reference to the radial plane refers, of course, to a plane transverse to the axis of the particular part such as the flange, washer, ring or shell.
- the stop faces on the teeth will also compress the wave washer to enable the teeth to move past each other and permit unthreading of the coupling ring in the event disassembly of the connector apparatus is desired.
- FIG. 1 is a sectional view illustrating an electrical connector coupling assembly utilizing the principles of the present invention
- FIG. 2 is an isometric view illustrating a portion of the ratchet washer and coupling ring
- FIG. 3 is an end view illustrating the pawl flange with a related portion of the shell and ring in section.
- FIG. 1 a coupling assembly is shown for securing one electrical connector shell 12 to a second electrical connector shell 14.
- the shells 12 and 14 are generally cylindrical and only a relevant portion of the front end 16 ofa conventional plug shell 12 being shown for telescoping engagement within the front end 18 of receptacle shell 14.
- the front end 16 of shell 12 has one or more radially outwardly extending keys such as 20 for engagement in respective keyways 22 located in the internal surface at the front end 18 of shell 14.
- the keys and keyways serve to properly align the shells ensuring correct engagement between socket contacts, one of which is indicated by broken lines 24 in shell 12 and pin contacts, one of which is indicated by broken lines 26 in shell 14.
- the contacts 24 and 26 are secured in conventional dielectric inserts (not shown) in turn secured in the respective shells in accordance with accepted and conventional practice.
- the coupling assembly 10 includes a coupling ring 28 having threads 29 formed on the internal surface thereof adjacent the front end of the ring for engagement with threads 30 on the external surface of the front end 18 of shell 14 to axially move the shells toward each other and provide secure electrical engagement between the contacts.
- An enlarged bore 31 formed in the ring 28 receives a radially outwardly extending flange 32 formed on'shell 12 intermediate opposite axial ends of shell 12 with the bore having a shoulder 34'for engaging the front radial face of flange 32.
- the flange 32 and shoulder 34 limit movement of the ring 28 relative shell 12 in one or a rearward direction.
- the bore 31 also receives a ratchet washer 36 having integrally formed axially extending ratchet teeth 38 on the front radial face thereof for engagement with axially extendingpawl teeth 40 integrally formed on the rear radial face of flange 32.
- a spring wave washer 42 having a nominal'wall thickness between 0.1 inch and 0.125 inch, depending on the connector shell size, is located in bore 31 to engage the rear radial face of washer 36 and thewashers 36 and 40 are held in bore 31 by a retaining ring 44.
- Retaining ring 44 is secured in the rear end of ring 28 by a series of closed annular teeth on the external surface thereof which are force fit past similarly sized and shaped teeth on the internal surface of the rear end of bore 31 to interlock the teeth and secure the rings and washers on the shell 12.
- Axially extending slots or recesses 46 are formed in the enlarged diameter surface of rear bore 31 of ring 32 for receiving teeth or keys 48 extending radially outwardly from the periphery of ratchet washer 38 and integrally formed thereon.
- the plurality of keys and keyways aid in maintaining the angle of the ratchet washer relative the axis of the ring and distribute the load transferred between the ring and washer.
- the ratchet washer 36 will therefore rotate with the ring 28 and is biased axially of shell 12 by the wave washer 42 against keyway 46.
- the wave washer 42 is assembled in bore.
- the ring 28 and washer 36 are thus rotatably mounted or carried by the shell 12 with both capable of limited axial movement of the shell and the washer capable of limited axial movement relative the ring.
- the ratchet teeth 38 and the detent or pawl teeth 40 may be formed accurately by investment casting, for
- Teeth 40 are provided about the complete periphery of the respective radial face or plane of flange 32 perpendicular to the shell axis, but only four equiangularly spaced teeth 38 are provided on the corresponding radial face or plane of washer 36.
- Each tooth 40 on flange 32 has a leading or pawl cam face 50 having a relatively small angle of substantially 30 to the radial face or plane of the flange for engagement with a respective leading or ratchet cam face 52 of similar small angle to the front radial face or plane of washer 36 on each of the four teeth 38.
- the faces 50 and 52 enable rotation of the ring 28 under relatively little additional force in one direction of rotation of the coupling ring 28 and washer 42 for threading ring 28 on shell 14, since the teeth faces 50 and 52 act as cams or as cam means and cam follower means to compress the spring wave washer 42 against its bias.
- the key means enables relative axial movement of the teeth for automatic disengagement against the bias of spring 42 so that the teeth may move past each other during rotation of ring 28 in the threading direction.
- the engaged teeth hold or resist rotation of the ring until a predetermined force or torque is applied to the coupling ring for threading it on the mating shell'whereupon the cam faces automatically move the teeth independentlyjof the shell and ring to disengage the ratchet teeth and washer from the pawl teeth and flange.
- the detent or stop means engage to prevent rotation in the loosening or opposite direction unless a substantially greater force is applied to loosen the rings than the force required to couple the rings.
- each pawl tooth 40 is inclined at a relatively large or'steep angle of substantially 60 to the radial face of flange 32 for engagement with a detent or ratchet stop face 56 on each ratchet tooth 38 of washer 36 and arranged at a similar steep angle to the washer radial plane or face to resist rotation in the opposite direction between the flange and washer and thereby'prevent loosening of the coupling assembly 10 from shell 14.
- substantially twice the force is required to loosen the threads 29 and 30 as is required to thread the same, since the difference between the threading and unthreading forces is related to the'difference between the angles of the cam and stop faces.
- the ring 28 receives the flange 32 in bore 31 in abutment with shoulder 34. Then the washer 36 is assembled in the bore 31 with key 48 located in the slot or 31 followed by the assembly of retaining ring 44 so that the coupling assembly is retained on shell 12 with the teeth 38 biased axially by the washer 42 for engagement between teeth 40.
- the front end 16 of shell 12 is telescoped in the front end 18 of shell 14 with the key 20 engaged in keyway 22 to angularly align the contacts 24 and 26.
- the thread 29 on coupling ring 28 is engaged with the thread 30 on shell 14 and the coupling ring 28 rotated in a threading or one direction in response to the application of a predetermined force to move the front ends of the shells toward each other as indicated by dashed lines 58 for coupling the shells.
- Rotation of the ring 28 rotates the ratchet washer 36 since the washer 36 is keyed to ring 28 by the key means 46 and 48.
- each ratchet washer tooth 38 moves past respective cam faces 50 on the pawl teeth 40 against the bias of wavewasher 42 by compressing the spring or wave washer enough to enable axial displacement corresponding to the height of the teeth.
- the reverse or stop faces 54 will act as pawls or detents in cooperation with stop faces 56 to prevent rotation in the opposite or unthreading direction despite the application of a second force substantially greater than the force required to thread the ring onto shell 14.
- the shells l2 and 14 are now held securely against vibration and other forces tending to loosen the coupling ring.
- stop faces 54 and 56 will also act as cam means and cam follower means and move past each other against the bias or pressure of the spring wave washer 42; however, the force required for this movement in the opposite or uncoupling direction is substantially greater than that required for rotation in the direction for coupling the shells or the second force resulting from ambient conditions.
