a bottom plate adapted to be operably coupled with the mobile device;

a locking region disposed on an edge of the bottom plate; and

a towel bar operably coupled with the bottom plate, the towel bar having a quadrilateral cross section defining at least a first engaging surface and a second engaging surface;

wherein the towel bar is adapted to engage an accessory device at least at one of the first engaging surface or the second engaging surface to couple the accessory device with the mobile device.

2. The connector assembly of claim 1 , wherein the bottom plate includes a recessed region, wherein the towel bar extends across the recessed region to define an opening to engage the accessory device.

3. The connector assembly of claim 2 , wherein the accessory device includes a hand strap configured to be inserted through the opening.

4. The connector assembly of claim 2 , wherein the towel bar includes at least one locking ledge positioned between the first engaging surface and the recessed region.

5. The connector assembly of claim 4 , wherein the at least one locking ledge includes a first engaging surface extending along a plane parallel to the first engaging surface of the towel bar and a second engaging surface positioned adjacent to the first engaging surface of the at least one locking ledge.

6. The connector assembly of claim 5 , wherein the accessory device includes a cradle having an engaging arm configured to extend towards the recessed region and engage the first engaging surface of the towel bar.

7. The connector assembly of claim 6 , wherein the engaging arm includes a protrusion adapted to engage at least one of the second engaging surface of the towel bar or the first engaging surface of the at least one locking ledge.

8. The connector assembly of claim 5 , wherein the accessory device includes a quick release buckle.

9. The connector assembly of claim 8 , wherein the quick release buckle includes a resilient body and coupling portion adapted to engage the first engaging surface of the at least one locking ledge.

10. The connector assembly of claim 9 , wherein the resilient body of the quick release buckle is adapted to flex inwardly to be inserted into the opening formed by the recessed region and the towel bar and to engage the second engaging surface of the at least one locking ledge.

11. The connector assembly of claim 10 , wherein the quick release buckle further includes an opening dimensioned to receive a strap.

12. The connector assembly of claim 1 , wherein the locking region includes a channel extending in a longitudinal direction and an engagement member positioned at an end of the channel.

13. The connector assembly of claim 12 , wherein the engagement member includes a protrusion extending into the channel.

14. A connector assembly for a mobile device, the connector assembly comprising:

a bottom plate adapted to be operably coupled with the mobile device;

a towel bar operably coupled with the bottom plate, the towel bar having a quadrilateral cross section defining at least a first engaging surface extending along a plane and a second engaging surface extending along a plane, wherein the towel bar and the bottom plate cooperate to define an opening therebetween; and

at least one locking ledge extending into the opening formed by the towel bar and the bottom plate, the at least one locking ledge defining a first engaging surface extending along a plane and a second engaging surface extending along a plane;

wherein the towel bar is adapted to engage an accessory device at least at one of the first engaging surface or the second engaging surface to couple the accessory device with the mobile device, the accessory device including a cradle having an engaging arm configured to extend towards a recessed region and engage the first engaging surface of the towel bar.

15. The connector assembly of claim 14 , wherein the first engaging surface of the at least one locking ledge is recessed relative to the first engaging surface of the towel bar.

16. The connector assembly of claim 14 , wherein the bottom plate includes the recessed region, wherein the towel bar extends across the recessed region.
