Definitions
- An electrical connector including plug and receptacle shells, a coupling ring rotatably mounted on one shell and arranged to be rotatably coupled to the other shell, and a locking device preventing rotation of the coupling ring with respect to the rotatably mounted shell.
- the locking device includes an axially compressible wave washer coupled to the coupling ring and an apertured lock ring axially movable towards the wave washer by action of the connector shell being coupled to force the detents into the apertures as the wave washer is compressed to prevent release by lower torques associated with vibrational effects.
- the lock ring also includes resilient plastic sealing rings which engage the two shells during coupling action and provide a seal across the shells.
- Connectors of this type have been utilized in the aircraft and other industries where shock and other vibrational effects are encountered which can cause accidental rotational movement of the coupling ring, thereby releasing one of the shells.
- the unintentional release of the connector shells results in disruption of the circuits connected thereby and is naturally objectionable.
- safety wire has been fastened to the coupling ring and at least one of the shells to prevent rotation of the coupling ring.
- other locking devices have been provided which are moved to their locking position after the connector shells have been coupled.
- connectors of this type When used in industry, connectors of this type are often installed in locations where the release features of the connector are not easily visible; and therefore, it is not always possible to determine the particular steps required for release of the connector. Under these circumstances, it is not uncommon that attempts are made to release the connector shells by forcing the coupling ring to rotate without being first released, resulting in damage to the connector.
- Another problem associated with connectors of this type involves the sealing of the shells together against environmental effects.
- the coupling action between the connector shells places their dielectric members in an abutting relationship to seal all or most of the contacts.
- the arrangement of the sealing members is determined by the action of the other connector parts during the coupling action and adequate sealing is not always easily obtainable.
- electrical connectors be provided which do not require a multi-stage releasing operation and which include sealing means for sealing the connector shells together when coupled.
- This invention relates to a locking device for connectors of the type utilizing a pair of connector shells and a rotatable coupling for coupling the shells together and more particularly, to a locking device which maintains the coupling action during vibration of the connector while permitting release of the connector shells during intentional rotation of the coupling ring by the application of torques higher than those associated with vibrational effects.
- the locking device of the invention includes locking means which are operative between the coupling ring and one of the two shells. to prevent relative rotation thereof and includes an axially compressible resilient member and a lock ring member normally spaced apart axially when the shells are uncoupled. Adjacent surfaces of the members include means for their being intermated together as one or both of the members are axially moved together during the coupling operation.
- the intermating means when engaged, provides resistance against accidental application of lower torques associated with vibrational effects while being releasable during the application of higher torques associated with intentional rotation of the coupling ring.
- the lock ring member includes sealing means interposed between the shells such that when the shells are coupled, the sealing means provides a seal between the shells without reducing the effectiveness of the lock ring member with respect to the desired locking action.
- the connector also includes visual means for indicating the different positions of the locking means when the intermating means are in a non-engaging and engaging relationship.
- These visual means advantageously include one or more annular slots in the coupling ring to reveal the presence or absence of axial movement of one or both of the members to reveal whether the locking means has been engaged.

- insert 22 is constructed of front section 22a which may be composed of a resilient or hard dielectric material, intermediate section 22b which is usually hard for retaining contacts 24 and rear grommet 220 which is usually resilient and seals insulated wire 28.
- Axially aligned bore sections 30a, 30b, and 300 extend through insert 22 and receive contacts 24.
- Clip 32 is positioned in bore section 30b and serves to retain contacts 24.
- Insert sections 22a, 22b and 220, bonded together to form a mono-block assembly, are retained in shell 12 by insert retainer ring 34 positioned in groove 36 of shell 12.
- Clamp shell 38 provides support for insert 22c.
- plug shell 12 includes radially flanged portion 40 rotatably coupled to coupling ring 16 by retainer ring 18 and axially extending inner sleeve 42 disposed within hollow interior 44 of ring 16 and spaced apart from threaded portion 20.
- Inner sleeve 42 is arranged to telescope within shell 14 with key 46 being disposed within keyway 48 during such coupling action.
- Elongated radially flange portion 50 of coupling ring 16 is outwardly spaced apart from sleeve 42 to form coupling slot 51, and outer sleeve 52 is spaced around flange portion 40 to complete the arrangement.
- Flange portions 40 and 50 are axially spaced apart and include inner faces 54 and 56 which form inner pocket 58 provided with a locking device of the invention.
- a locking device becomes operative for locking coupling ring 16 in a fixed position relative to plug shell 12. Action of the locking device thereby prevents accidental release of coupling ring 16 by shock or other vibrational effects.

- Lock ring 72 serves as a second member of the locking means and is disposed in pocket 58 in axial alignment with washer 60 and opositely disposed with respect to threaded portion 20.
- Rear face 74 from ring 62 is provided with a plurality of recesses as illustrated by apertures 76 arranged to receive detents 66 in intermating engagement during axial movement of at least one of faces 62 and 74 towards the other.
- washer 60 and lock ring 72 are normally spaced apart axially and include adjacent faces 62 and 74 with intermateable means illustrated by detents 66 and aperture 76.
- Frontwardly disposed on lock ring 72 is front face 78 in juxtaposition with radial shoulder 55 forming inner face 56 of coupling ring 16.
- Front face 78 is provided with portion 79 disposed in slot 51 and arranged to be movable axially by shell 14 during the coupling action.
- portion 79 of lock ring 72 is engaged by shell 14 and is inwardly moved towards washer 60 whose front face 62 is being rotated with respect to rear face 74 by movement of coupling ring 16.
- detents 66 become engaged with oppositely positioned apertures 76.
- detents 66 can be released by further rotation of ring 16; and as a result, ring 16 is rotated until washer 60 is compressed to an extent preventing further rotation.
- detents 66 rachet between apertures 76 to their final position.
- excess apertures 76 over detents 66 are provided so that only limited rotational movement is required to move detents 66 to their final locking position from a prior engagement position.
- the locking position of plug 14, illustrated in FIG. 2, is visually indicated through annular slots 82 provided in coupling ring 16 and color may be provided on lock ring 72 to emphasize its movement to locking position 90.
- Annular slots 82 may be arranged to reveal axial movement of one or both of the locking members 60 and 72 depending on the particular construction of the locking device.
- detents 66 are formed to readily mate and unmate in apertures 76. However, as wave washer 60 is compressed, substantial force will be developed to resist further coupling action and will be sufficient to prevent unmating by vibration. Preferably, detents 66 are rounded with minimum areas of contact on rear face 74 of lock ring 72.
- the intermating means may be interchanged, preferably detents 66 are present on washer 60.
- This arrangement utilizes the compressible high points of the washer for the detents csn be readily manufactured as can the apertured lock ring.
