VIA'A'I'A INVENTOR. WOLFGANG W. JENSEN ATTORNEYS I CABLE STRAIN RELIEF DEVICE BACKGROUND OF THE INVENTION Headsets have been provided for radio telephone operators, aircraft crewmen, or other personnel for use in communications systems. These headsets have either been mounted to the users head by means of a headband or other supporting arrangement, or have been of the self-supporting type adapted to fit over'the users ear. The cable carrying the leads to the headset typically extends from the headset and hangs freely across the body of the user. The weight of this cable pulling against the headset is somewhat uncomfortable to the user, especially where the headset is used over a long period of time. Moreover, where the user is active and moves his body or turns his head frequently throughout his work activities,
then the freely hanging cable oftentimes interferes with his movements and is otherwise a nuisance. The expediency of merely affixing the cable to the users wearing apparel is not entirely satisfactory where the user changes positions frequently, since this requires adjusting and readjusting of the free length of the cable. Thus, the need has been recognized for a small, simple and inexpensive device for supporting a headset cable in a manner relieving the strain or weight of the cable from the users head, and also which facilitates easy and fast adjustment of cable position and length.
SUMMARY OF THE INVENTION AND OBJECTS It is a general object of the invention to provide a newand improved cable strain relief device for use with communications headsets.
Another object is to provide a device of the type described supporting a headset cable to the apparel of a user and relieving cable weight from the users head for improved comfort and reduced fatigue.
Another object is to provide a cable strain relief device releasably attached to the apparel of the user and which releasably holds the cable in a position which is readily and easily adjusted through both lengthwise and pivoting adjustments.
Another object is to provide a cable strain relief device of the type described bed which is relatively small and light weight, inexpensive, and comprises a relatively small number of parts.
The invention provides a housing and plunger formed with transverse bores which, when aligned, receive the headset cable. Slots in the housing and plunger facilitate insertion and removal of the cable. A spring in the housing urges the plunger in a direction forgripping the cable against the, housing. A stop on the plunger end limits plunger travel to prevent unintended separation of the cable from the housing. Inward displacement of the plunger provides lengthwise adjustment of the cable, while rotation of the housing with respect to a mounting clip provides angular adjustment.

FIG. 2 is an enlarged perspective view of the strain relief device illustrating the use thereof in supporting a headset cable;
FIG. 3 is a side elevational view of the strain relief device shown in gripping relationship with a cable; and,
FIG. 4 is a side elevational view, partially in axial cross section, of the strain relief device.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and particularly FIG. 1 a strain relief device in accordance with the invention is illustrated generally at 10. This device is clipped to the coat edge or lapel 12 of a user 14 for supporting a headset cable 16. The A cable depends from a communications .headset l8, shown in phantom view as mounted above the users ear. Headset 18 may be of the self-supporting type illustrated in copending application Ser. No. 839,016, filed July 3, 1969. This type of headset is adapted to be supported on the user's ear with a voice tube 20 having its distal end extending to the users mouth and an acoustic tube 22 insertable into the auditory canalof the user. Cable 16 supplies electrical signals through leads connected with microphone and receiver transducers within the housing of the headset.
Referring to FIG. 2 strain relief device 10 is illustrated in greater detail. Device 10 comprises a cable gripping housing assembly 24 pivotally mounted on a clip assembly 26. As-
sembly 24 is adapted to releasably grip headset cable 16 for 4 carrying a part of the cable weight when the clip assembly is secured to the users wearing apparel. I
FIGS. 3 and 4 illustrate details of the component elements of device 10. Cable gripping assembly 24 comprises a housing 28, shown as cylindrical, defining an internal cavity 29 having a closed end 30 and an open end 32. A transverse bore 34'is formed through the walls of the housing and is of a diameter sized to cradle or receive headset cable 16, as best illustrated in FIG. 3. A transverse slot 36 is formed through a side of the housing and extends into the bore on the side thereof remote from housing open end 32. Slot 36 is sized with a width adapted to freely permit insertion and removal of the cable. A square boss 38 is molded integral with housing 28 on a side thereof remote from the opening definedby housing slot 36. An integral stud 40 projects from boss 38, and this stud is formed with a locking shoulder 42.
A slide or'plunger 44, shown as cylindrical, is mounted for sliding movement within housing cavity 29. A transverse bore is formed in the housing with a diameter sized to cradle the cable, as shown in FIG. 3. A transverse slot 48 is formed on a side of the plunger for registry with housing slot 36, and extends into bore 46 on a side thereof remote from housing open end 32. An operating button 50 is provided with a skirt SI defining an internal bore for mounting on a reduced projecting end 52 of the plunger. A self-threading screw 55 is provided to lock the button on the plunger.
The circumferential shoulder 56 of the button cooperates with housing open end 32 in a manner preventing unintended or complete release of the cable from the housing. In thecable gripping position of FIG. 3, shoulder 56 is spaced from housing end 32. For release and longitudinal adjustment of the cable, button 50 is pressed and the plunger displaced inwardly until shoulder 56 stops against the housing. At this point the cable is free to slide along bores 34 and 46 to the desired new position, but right-hand edge of plunger slot 48 has not cleared the left-hand edge of housing slot 36 sufficient to permit removal of the cable through these slots.
Means are provided to yieldably urge plunger 44 in a direction tending to move it out of housing cavity 29. This means may. comprise the illustrated compression spring 58 mounted between housing end wall 30 and plunger 44. With a length of the cable in place in the aligned bores of the plunger and housing, spring 58 is effective to urge the plunger outwardly for firmly gripping the cable.
Clip' assembly 26 comprises a pair of jaws 60,62 pivotally mounted together by means of rivet or fastener 64. A coil spring 66 is mounted on fastener 64 with its outwardly projecting ends yieldably urging the clip jaws together at gripping end 68 in a conventional manner for releasably gripping the users wearing apparel. An opening 70 is provided in upper jaw 60 for mounting the clip assembly over locking shoulder 42 of stud 40. Means are provided for resiliently locking the clip assembly to the strain relief device 10. A variety of means would be satisfactory, but preferably a resilient locking ring' '72, which may be, for example, a bowed E-ring, is mounted between locking shoulder 42 and the inner surface of jaw 60. The resiliency of E-ring 72 acting against the locking shoulder urges jaw 60 into releasable engagement with the flat surface of housing boss 38. This insures that the se cted pivotal position of housing 24 with respect to clip assembly 26 is maintained so that the cable extends in the most comfortable posi tion on the wearers body. At the same time, the user can easily readjust this positioning by turning the housing with respect to the clip assembly.
For initial assembly and installation on a cable, spring 58 and plunger 44 are mounted in housing cavity 29. The plunger is pushed inwardly far enough to allow the cable to be inserted through the plunger and housing slots. The plunger is then released to permit the spring force to clamp the cable, and button 50 is then fastened on the end of the plunger by screw 55 preventing complete release of the cable.
In use of the strain relief device 10, assume that a cable has been installed and is gripped as illustrated in FIG. 3. For lengthwise adjustment of the cable, the user may easily grasp housing assembly 24 in one hand and move plunger 44 into the housing against the force of spring 58 until the cable is released. The user then slides the cable to the desired position, releases the plunger, and the cable is again gripped in the new position. The force of spring 58 is effective to move the plunger outwardly and carry the cable into its seated position on the semicircular portions of housing bore 34. The yieldable force of the spring retains the cable in locking engagement between plunger bore 46 and housing bore 34.
From the foregoing it is apparent that there has been provided a new and improved strain relief eevice for supporting a headset cable to the wearing apparel or a user. The elements are relatively small, simple and inexpensive to build. In user, the major portion of the weight of the headset cable is supported through a clip arrangement on the users wearing apparel to reduce the user's fatigue. The cable is maintained in the desired position on the user permitting freedom of body movement without interference from the cable. The cable position with respect to the clip assembly is readily adjusted through both lengthwise and pivotal positioning. Means is provided to prevent unintended separation of the cable from the device.
While the foregoing embodiment is considered to be preferred, it is understood that numerous variations in the details and arrangement of parts, which have been described and illustrated in order to explain the nature of the invention. may be made by those skilled in the art within the spirit and scope of the invention as expressed in the appended claims.
