BACKGROUND OF THE INVENTION
Accessory plugs and cables, such as for audio jacks, are often attached to a portable communication device. Retainers may be used to retain the accessory plugs and cables in place on the portable communication device. Many of these retainers use screws to facilitate retention. However, inadvertent pulling or tugging on the accessory plug and/or cable may impart high forces on the retainer and/or screw.

DETAILED DESCRIPTION OF THE INVENTION
As noted above, it is important that retainers withstand high forces imparted by pulling or tugging of the accessory plug and cable, and maintain retention of the accessory plug and cable to the portable communication device. Accordingly, there is a need for an improved retainer for retaining an accessory plug and cable to a portable communication device.
Briefly, therefore, there is provided herein an improved retainer for retaining an accessory plug and cable to a portable communication device. The retainer, in accordance with one example, includes a main body having a top wall, a first side wall, a second side wall spaced opposite the first side wall, a front wall, and a rear wall spaced opposite the front wall along a longitudinal axis. The top wall, the first side wall, the second side wall, the front wall, and the rear wall define an interior cavity sized and shaped to receive the accessory plug. The front wall defines a front opening that extends into the interior cavity and is sized and shaped to receive a portion of the cable. The front wall includes a first hook and a second hook each positioned below the front opening. The rear wall includes a third hook extending forward into the interior cavity. The retainer is configured to be moved forward linearly, and parallel to the longitudinal axis, to secure the first hook, the second hook, and the third hook to the portable communications device.
FIGS. 1-14 illustrate a retainer 10 for retaining an accessory plug 14 and a cable 18 to a portable communication device 22. In the illustrated example, the portable communication device 22 is a portable handheld radio, and the accessory plug 14 and the cable 18 are integrally formed together as a single piece to be coupled to a headphone (not shown). In other examples, the portable communication device 22 is a phone, a tablet, or other portable communication device. Additionally, in other examples, the accessory plug 14 and the cable 18 are coupled to devices other than a headphone (e.g., other audio accessory devices). A system includes the retainer 10 and the portable communication device 22.
With reference to FIGS. 1-3, in the illustrated example, the retainer 10 includes a main body 26 having a top wall 30, a first side wall 34, and a second side wall 38 spaced opposite the first side wall 34. The main body 26 also includes a front wall 42, and a rear wall 46 spaced opposite the front wall 42 along a longitudinal axis A1 (FIG. 1). The top wall 30, the first side wall 34, the second side wall 38, the front wall 42, and the rear wall 46 define an interior cavity 50 (FIGS. 2 and 3) sized and shaped to receive the accessory plug 14.
In the illustrated example, the first side wall 34 extends parallel to the second side wall 38, and the front wall 42 extends parallel to the rear wall 46. The main body 26 has a generally rectangular shape when viewed from above or from the side. The top wall 30 transitions into the first side wall 34 with a beveled or filleted edge. Similarly, the top wall 30 transitions into the second side wall 38 with a beveled or filleted edge. Other examples include different shapes and/or sizes for the retainer 10 than that illustrated, such as shapes that are more elongated, or square, or shapes where the front wall 42 is not parallel to the rear wall 46, and/or the first side wall 34 is not parallel to the second side wall 38.
With continued reference to FIGS. 1-3, the first side wall 34 and the second side wall 38 each include a set of ribs 54 that extend parallel to the longitudinal axis. The ribs 54 facilitate gripping of the retainer 10. In other examples, the retainer 10 includes no ribs 54, or other numbers and arrangements of ribs 54 than that illustrated.
With reference to FIGS. 2 and 3, the front wall 42 defines a front opening 58 that extends into the interior cavity 50 and is sized and shaped to receive a portion of the cable 18. As illustrated in FIGS. 2 and 3, the front wall 42 has an omega shape (as viewed for example along the longitudinal axis A1 in FIG. 3) that defines the front opening 58. In the illustrated example, at least a portion of the front opening 58 has a circular shape.
With continued reference to FIGS. 2 and 3, the front wall 42 includes a first hook 62 positioned below the front opening 58, and a second hook 66 positioned below the front opening 58. The rear wall 46 includes a third hook 70 extending forward into the interior cavity 50, and a fourth hook 74 extending forward into the interior cavity 50. In the illustrated example, the third hook 70 and the fourth hook 74 are coupled to one another with a bridge 78. The first hook 62 and the second hook 66 are front hooks, and the third hook 70 and the fourth hook 74 are rear hooks. In some examples, only a single rear hook (e.g., third hook 70) is provided, rather than multiple rear hooks.
As illustrated in FIGS. 2 and 3, each of the first hook 62 and the second hook 66 includes an L-shaped arm having a first segment 82 that extends down vertically, and a second segment 86 that extends perpendicularly away from the first segment 82. As illustrated in FIGS. 2 and 3, the second segment 86 of the first hook 62 and the second segment 86 of the second hook 66 extend laterally away from one another, and are separated from one another by a gap G1. The front opening 58 has a diameter D1, and the gap G1 is smaller than the diameter D1. The first hook 62 and the second hook 66 are each flexible, and are able to flex laterally apart from one another.
With continued reference to FIGS. 2 and 3, each of the third hook 70 and the fourth hook 74 also includes a first segment 82 that extends down vertically, and a second segment 86 that extends perpendicularly away from the first segment 82. The second segments 86 of the third and fourth hooks 70, 74 extend laterally toward one another. In some examples, the third hook 70 and/or the fourth hook 74 is flexible, and is able to flex forward for example about an axis A2 (FIG. 1) that is perpendicular to the longitudinal axis A1. In some examples, the second segments 86 of the third and fourth hooks 70, 74 extend laterally away from one another.
With reference to FIGS. 1, 2, and 9-14, the retainer 10 also includes a latch 90 coupled to the main body 26 along the rear wall 46, and is movable relative to the main body 26 along an axis A3 (FIG. 9) that is perpendicular to the longitudinal axis A1. The latch 90 may be moved vertically between an unlocked (e.g., raised) position, as seen in FIGS. 1 and 9-13, and a locked (e.g., lowered) position, as seen in FIGS. 2 and 14. In some examples, when the latch 90 is in the unlocked position, the latch 90 is spaced vertically from the third hook 70 and the fourth hook 74, and when the latch 90 is in the locked position, the latch 90 is in contact with the third hook 70 an the fourth hook 74. With reference FIG. 10, in the illustrated example the latch 90 includes a detent arm 94 having notches 98 corresponding to a locked (e.g., lowered) and unlocked (e.g., raised) state. The rear wall 46 of the main body 26 includes a stopper 100, and a protrusion 102 positioned below the stopper 100 that engages and disengages the notches 98 to lock and unlock the latch 90, respectively. In other examples, the rear wall 46 includes the detent arm 94 and the notches 98, and the latch 90 includes the protrusion 102. Other examples include other types of detent mechanisms (e.g., for snap-fit engagement between the latch 90 and the main body 26) than that illustrated. In some examples, no detent mechanism is provided. Instead, the latch 90 is held for example in the locked position relative to the main body 26 via a frictional fit with the main body 26, or with a fastener, or with other structures. With reference to FIG. 1, in the illustrated example the latch 90 also includes latch lock arms 104 that slide into corresponding recesses 106 (e.g., notches) on the portable communication device 22 when the latch 90 is locked, to further inhibit or prevent the retainer 10 from sliding along the longitudinal axis A1.
With reference to FIGS. 3-6, the retainer 10 is coupled to the accessory plug 14 and the cable 18, such that the accessory plug 14 is positioned within the interior cavity 50 of the main body 26, and the cable 18 extends out of the front opening 58. As illustrated in FIG. 4, the cable 18 includes a first portion 108 having a first diameter, and a strain relief portion 110 having a second diameter that is larger than the first diameter. The strain relief portion 110 may have a tapering diameter that increases moving toward the accessory plug 14. The diameter of the first portion 108 is larger than the gap G1, but smaller than the diameter D1 of the front opening 58.
With continued reference to FIG. 4, the retainer 10 is coupled to the accessory plug 14 and the cable 18 by initially tilting the retainer 10 relative to the longitudinal axis A1. A lower portion of the omega-shaped front wall 42 is then clipped (e.g., snapped) over the first portion 108 of the cable 18. During this initial attachment, the first and second hooks 62, 66 flex laterally outwardly apart from one another, opening the gap G1 further, and allowing the cable 18 to snap upwardly into the front opening 58. In some examples, the diameter of the first portion 108 is the same or smaller than the gap G1.
With reference to FIG. 5, the retainer 10 is then moved (e.g., slid) linearly along the cable 18 (e.g., along the longitudinal axis A1), until the main body 26 is generally positioned over the accessory plug 14. The retainer 10 remains tilted during this movement.
With reference to FIG. 6, the retainer 10 is then tilted down over the accessory plug 14, such that the accessory plug 14 is at least substantially enclosed by the walls of the main body 26, and the rear wall 46 and third and further hooks 70, 74 extend down behind the accessory plug 14. In this position, a section of the strain relief portion 110 extends through the front opening 58.
As described above, the strain relief portion 110 has a diameter that is larger than the diameter of the first portion 108 of the cable 18. In some examples, the diameter of the strain relief portion 110 is large enough such that the first and second hooks 62, 66 cannot flex far enough apart to accommodate the diameter of the strain relief portion 110. The retainer 10 therefore cannot simply be lifted up vertically off of the accessory plug 14 once it has been coupled to the accessory plug 14 (FIG. 6). Instead, the retainer 10 may remain on the accessory plug 14 and the cable 18, and it is not necessary to remove or re-attach the retainer 10 to the accessory plug 14 and the cable 18 prior to every use of the accessory plug 14 and the cable 18.
With reference to FIGS. 7-14, once the retainer 10 has been coupled to the accessory plug 14 and the cable 18, the retainer 10 may then be used to couple and secure the accessory plug 14 and the cable 18 to the portable communication device 22. For example, and as illustrated in FIGS. 7 and 8, at least one pin 114 (e.g., electrical contact pin) extends from the beneath the accessory plug 14. In the illustrated example, two pins 114 extend from the accessory plug 14. The pins 114 are sized and shaped to be received within corresponding plug openings 118 in an outer wall 122 of the portable communication device 22. Insertion of the pins 114 into the plug openings 118 may create an electrical connection within the portable communication device 22 (e.g., with a printed circuit board).
With continued reference to FIGS. 7 and 8, a seal 126 includes apertures 130 that receive the pins 114. The seal 126 is sized and shaped to be coupled to the accessory plug 14, and to be positioned at least partially between the accessory plug 14 and the outer wall 122 of the portable communication device 22. The outer wall 122 defines a recess 134 along the portable communication device 22, and the seal 126 is sized and shaped to be positioned within the recess 134. The seal 126 may provide a seal between the accessory plug 14 and the portable communication device 22, and may inhibit or prevent water from entering the portable communication device 22.
With reference to FIGS. 1 and 9, the outer wall 122 also defines a first slot 138 sized and shaped to receive a portion of the first hook 62 when the retainer 10 is moved forward linearly along the longitudinal axis A1, a second slot 142 sized and shaped to receive a portion of the second hook 66 when the retainer 10 is moved forward linearly along the longitudinal axis A1, a third slot 146 sized and shaped to receive a portion of the third hook 70 when the retainer 10 is moved forward linearly along the longitudinal axis A1, and a fourth slot 150 sized and shaped to receive a portion of the fourth hook 74 when the retainer 10 is moved forward linearly along the longitudinal axis A1. The plug openings 118 extend perpendicularly into the outer wall 122, and are positioned between the first slot 138 and the third slot 146 along the outer wall 122. As described above, the outer wall 122 also includes the recesses 106 that receive the latch lock arms 104 of the latch 90. With reference to FIGS. 2 and 8, in the illustrated example the retainer 10 also includes a detent notch 150 along a side of the retainer 10. The detent notch 150 is sized and shaped to engage a detent bump 154 along the portable communication device 22.
With reference to FIGS. 9-14, in the illustrated example the retainer 10 is coupled to the portable communication device 22 in three steps. As illustrated in FIGS. 9 and 10, in the first step the retainer 10, the accessory plug 14, and the pins 114 are moved (e.g., pressed down) toward the outer wall 122 of the portable communication device 22 along a direction perpendicular to the longitudinal axis A1, until the seal 126 is positioned within the recess 134, and the pins 114 are extended into the plug openings 118.
With reference to FIGS. 11 and 12, in the second step the retainer 10 is then moved forward linearly, and parallel to the longitudinal axis A1, to engage the first hook 62, the second hook 66, the third hook 70, and the fourth hook 74 into the respective first slot 138, second slot 142, third slot 146, and fourth slot 150 of the portable communication device 22. In the illustrated example, the first hook 62, the second hook 66, the third hook 70, and the fourth hook 74 engage the first slot 138, the second slot 142, the third slot 146, and the fourth slot 150 simultaneously when the retainer 10 is moved forward linearly along the longitudinal axis A1. In some examples, movement of the retainer 10 during this second step may emit a “click” sound (FIG. 12). During this movement, and in the illustrated example, the detent notch 150 engages the detent bump 154.
With reference to FIGS. 13 and 14, in the third step the latch 90 is then moved (e.g., pressed down) from the unlocked (e.g., raised) position illustrated in FIG. 13 to the locked (e.g., lowered) position illustrated in FIG. 14 (e.g., along the axis A3). In some examples, movement of the latch 90 to the locked position may emit a “click” sound, for example as the protrusion 102 engages the notch 98 (FIG. 14). During this step, the latch lock arms 104 extend into the recesses 106.
Overall, and because of the arrangement of the hooks 62, 66, 70, and 74, the slots 138, 142, 146, and 150, and the latch 90 described above, the retainer 10 may be coupled quickly and securely to the portable communication device 22, and provide a strong cable pull retention, such that it is difficult to simply pull or tug on the cable 18 and detach the accessory plug 14 from the portable communication device 22. Additionally, and as described above, the retainer 10 may remain on the cable 18 when the accessory plug 14 has been detached from the portable communication device 22, such that it is not necessary to re-attach the retainer 10. Additionally, the arrangement of the seal 126 between the accessory plug 14 and the portable communication device 22 may inhibit or prevent water from entering the portable communication device 22 after the retainer 10 has been coupled to the portable communication device 22.
