Communication port

Abstract

A communication port is susceptible to contaminates such as dirt, dust, and moisture if not properly protected. A communication port that automatically protects against contaminates includes a housing defining an opening and configured to receive a device connector. A face plate is disposed on the housing. The face plate defines a window generally aligned with the opening. A door is slideably disposed on the housing and biased toward a position covering the opening and the window. Exerting a force on the door exposes the opening and the window.

Description

BACKGROUND

Communication ports are widely used to transmit data between electronic devices. For instance, universal serial bus (USB) ports are frequently used to transmit data between digital cameras and personal computers. A port used in this environment has minimal risk of exposure to contaminates such as dirt, dust, and moisture, which can reduce the effectiveness of the connection between the port and the electronic device, or alternatively, render the port completely inoperable. However, with the proliferation of portable electronic devices, there is an increased need for communication ports located outside a consumer's home where there is an increased risk for collecting contaminates inside an open communication port.

One known method for preventing exposure to contaminates is to provide a door or cover over the opening of the port. In most cases, however, existing port covers are actively employed, meaning that the user must manually remove the cover before connecting the electronic device to the communication port, and then manually replace the cover after the electronic device is removed. Although effective when used properly, these active covers cannot prevent contaminates from entering the port if the covers are not replaced.

Accordingly, a consumer port is needed that allows for passive protection against contaminates. In other words, a consumer port is needed that automatically covers the communication port when no electronic device is connected.

BRIEF SUMMARY

A communication port includes a housing defining an opening and configured to receive a device connector. A face plate is disposed on the housing. The face plate defines a window generally aligned with the opening. A door is slideably disposed on the housing and biased toward a position covering the opening and the window. Exerting a force on the door exposes the opening and the window.

DETAILED DESCRIPTION

A passive communication port automatically closes a door to protect a device connector from contaminants, such as dirt, dust, and moisture. The device connector is partially surrounded by a housing and accessible via an opening. A face plate covers a front part of the housing and includes window to allow access to the device connector via the opening. The door is located on the housing over the window and the opening. The door will remain closed until a force strong enough to overcome a bias pushing the door closed is overcome. When the door is open, the device connector is accessible through the window and the opening.

The Figures refer to exemplary embodiments wherein like numerals indicate like or corresponding parts. FIG. 1 illustrates a perspective view of an exemplary communication port 10 having a housing 12 with integrally formed clips 14 for connecting the port to another structure. The housing 12 may be formed from a non-conductive material, such as plastic. On a front side of the housing 12 is an access port that includes a self-closing door 16 that cooperates with a window in a face plate 18. The access port is configured to receive an electronic device 40 as shown in FIGS. 5 and 6 having a connection interface such as a USB interface, a parallel port interface, or a fire wire. Within the communication port 10, the consumer connection interface mates with a device connector 20, which in one embodiment, is installed through a back side of housing 12. The device connector 20 is supported within the communication port 10 by a retention mechanism 22. The retention mechanism 22 may include any mechanism for retaining the device connector 20 within the communication port 10, including, but not limited to, the application of side locks, a loose pick lock, or as shown in FIG. 1, a molded tray in which device connector 20 is rotated into the tray to provide additional push-out resistance when the consumer interface is mated with the device connector 20.

FIG. 2 illustrates an exploded view of the exemplary communication port 10 of FIG. 1. The face plate 18 includes a recessed portion 24 presenting a ledge 26 to support the door 16 when closed. Furthermore, the door 16 may include a lip 28 that extends toward the front of the housing 12 to allow an upward force to be applied to open the door 16. The lip 28 may also limit movement of the door 16 relative to the face plate 18. Both the door 16 and the face plate 18 are placed in slots 30 in the housing 12. When in the slots 30, the window of the face plate 18 is generally aligned with an opening defined by the housing 12. The face plate 18 may be locked in place with friction or a locking device (not shown) to prevent it from sliding in the slot. On the other hand, the door 16 is able to slide in the slot to cover the window and the opening. Moreover, the door 16 is biased to cover the window and the opening to prevent contaminants like dirt, dust and moisture from entering into the communication port 10. In one embodiment, a biasing device 32, such as a spring, a stretchable band, a block of foam, or any other device that may be stretched or compressed, is disposed on the door 16 and the housing 12. The biasing device 32 pushes against the housing 12 so that the door 16 covers the opening and window. As illustrated, the biasing device 32 may push against a boss 34 that may be generally v-shaped and integrally formed with the housing 12.

FIGS. 3 and 4 illustrate an embodiment of the biasing device 32 disposed on the door 16. As shown in FIG. 3, the door 16 may include a pair of posts 36 that support the biasing device 32 and give the biasing device 32 something to push against. FIG. 4 illustrates the door 16 being open and the biasing device 32 pushing against the boss 34. Even when the door 16 is closed, the biasing device 32 may continue to exert a force on the door 16 to, for instance, prevent rattling. However, exerting an upward force on the lip 28 pushes against the biasing device 32 and opens the door 16. Note that the clips 14, device connector 20, and retention mechanism 22 are not illustrated in FIG. 4 so that the biasing device 32 may be viewed more clearly.

FIGS. 5 and 6 illustrate the communication port 10 mounted to a structure 38 and an electronic device 40 is shown opening the door 16. Referring to FIG. 5, in operation, the electronic device 40 may be inserted into the recessed portion 24 of the face plate 18 and may exert a force on the lip 28 of the door 16 against the biasing device 32 to open the door 16. Referring to FIG. 6, with the door 16 open, the electronic device 40 may be plugged into the device connector 20, which prevents the door 16 from closing even though the biasing device 32 continues to push on the door 16 and the boss 34.

Furthermore, FIGS. 5-7 illustrate how the communication port 10 may be mounted to the structure 38. In FIGS. 5 and 6, the structure 38 presents a surface having inwardly extending walls 42 defining spaces. The clips 14 on the housing 12 extend into the spaces to limit movement of the communication port 10. Alternatively, FIG. 7 is a rear view of the communication port 10 mounted to the structure 38 via a locking mechanism 44. In this embodiment, the structure 38 presents the surface having inwardly extending walls 42 defining a gap. The locking mechanism 44 includes a lock 46 disposed on the side of the housing 12, that extends into the gap. As the lock 46 rests in the gap, movement of the communication port 10 is limited.
