The bezels are side stackable so that a variety of simplex and duplex bezels can be utilized in a panel cut-out.

Description

MULTIMEDIA BEZELS

Background of the Invention Field of the Invention

The invention relates to bezels for mounting a connector in a panel and in particular to multimedia bezels that provide for mounting of a variety of connectors in a standard panel cut-out.

Prior Art

In cable routing applications, access to a cable is often made at a panel that includes a connector mounted in the panel. The connector in the panel mates with a connector on the cable and allows cable to be coupled to the panel. The panel includes a cut-out that is sized to receive the connector. Currently, there are a wide variety of connector standards including ST, SC, RCA, BNC, etc. The cut-out in the panel must have a specific size and shape to provide for mounting the connector in the panel. Accordingly, a manufacturer must produce a variety of different panels having varying cut-outs in order to mount the various types of connectors. To complicate matters, the connectors may be mounted in the panel in simplex or duplex configurations. The need for panels having cut-outs that match specific connector types has several drawbacks. Producing a variety of panels having differing panel cut-outs increases manufacturing costs and also requires maintaining a large inventory of differing parts. In addition, when changing from one connection standard (e.g. SC) to a second connection standard (e.g. ST) in the field, the installer must remove the entire panel and install a new panel having the appropriate cut-out for the new connection standard.

Summary of the Invention:

The above-discussed and other drawbacks and deficiencies of the prior art are overcome or alleviated by the multimedia bezels of the present invention. The multimedia bezels of the present invention are designed to receive a variety of connectors and fit within a standard panel cut-out. The bezels include top and bottom notches that engage the edge of the panel cut-out. An opening in the body of the bezel receives the connector. A resilient section allows one of the sets of notches to deflect towards the body for insertion in the panel cut-out. Once within the panel cut-out, the resilient section presses against the edge of the panel cut-out to firmly mount the bezel in the panel. The body of the bezel may be parallel (flat) or at an oblique angle (angled) to the panel. Both the flat and angled embodiments include icon holding grooves for receiving an icon for coding the port. In the flat embodiment, the icon also prevents deflection of the resilient section and acts as a lock. The bezels are side-stackable so that a variety of simplex and duplex bezels can be utilized in a panel cut-out.

By using a bezel that fits a standard panel cut-out, manufacturing of the panels is greatly simplified. In addition, installing and modifying connections in the field is simplified. The bezels of the present invention may be installed in the panel from either the front or back of the panel without tools.

The above-discussed and other features and advantages of the present invention will be appreciated and understood by those skilled in the art from the following detailed description and drawings. Brief Description of the Drawings

Detailed Description of the Invention

FIGURE 1 is a front view of an angled bezel, shown generally at 10, in a first embodiment of the invention. The angled bezel 10 has a body section 12 having an opening 14 formed therein for receiving a connector. The opening 14 shown in FIGURE 1 is sized to receive a duplex SC fiber optic connector. In the ST and SC standards, the item that is mounted in the panel is commonly referred to as an

"adapter." In other non-ST and non-SC standards, such as coaxial cable, BNC, etc., the item mounted in the panel is commonly referred to as a ''connector." As used herein, the term "connector" should be construed to encompass both SC and ST adapters mounted in the panel and non-ST and non-SC connectors mounted in the panel. The angled bezel 10 includes a pair of top notches 16 and a pair of bottom notches 18. The top notches 16 and bottom notches 18 engage the edges of a panel cutout in order to mount the angled bezel 10 in the panel. Exterior surfaces 20, 22, 24 and 26 adjacent to the opening of each notch 16 or 18 are curved to ease installation and removal of the angled bezel 10 in a panel cut-out. A resilient section 28 is provided between the bottom notches 18 and the body 12. The angled bezel is preferably made from a resilient material (e.g. plastic) so that the resilient section 28 can be flexed and then return to its original position. To insert the angled bezel 10 in a panel cut-out, the top notches 16 are placed in the panel cut-out so that the panel extends into the top notches 16. The interference fit between the notches 16 and the panel edge prevents the bezel 10 from moving out of the panel cut-out. The bottom notches 18 are then pushed towards the panel. The angled bezel 10 may be inserted in the panel from either side of the panel. Therefore, either the curved surface 24 or the curved surface 26 contacts the edge of the panel cutout. The interference between the curved surface 24 or 26 and the edge of the panel cut-out causes the resilient section 28 to flex and the notches 18 move towards the body 12. Once the curved surface 24 or 26 that initially contacted the edge of the panel cutout clears the panel, the resilient section 28 forces the notches 18 away from the body 12 and snaps notches 18 around the edge of the panel cut-out. To remove the angled bezel 10 from the panel cut-out, the bottom notches 18 are pressed towards the body 12 while the angled bezel 10 is pulled from the panel cut-out. This disengages the panel edge from notches 18 and allows the angled bezel 10 to be removed.

The angled bezel 10 includes a pair of icon holding grooves 30 and 32 for receiving an icon for color coding or otherwise identifying the port. The opening 14 in body 12 receives a duplex connector and thus the length of the icon grooves 30 and 32 is sufficient to hold two icons, one for each port. The notches 16 and 18 define a plane that corresponds to the plane of the panel cut-out. The body 12 is at an oblique angle relative to the plane defined by the notches 16 and 18. This provides a gravity feed configuration in which a connector mounted in the angled bezel 10 is pointing towards the floor. FIGURE 3 is a perspective view of the angled bezel 10 clearly showing the icon holding grooves 30 and 32.

FIGURES 4-6 are respective front, side and perspective views of an alternative angled bezel 40. The angled bezel 40 is similar to angled bezel 10 shown in FIGURES

1-3. The single opening 14 is replaced with two openings 42 in body 12. The openings 42 each receive an ST fiber optic connector to form a duplex ST port.

FIGURES 7-9 are respective front, side and perspective views of an alternative angled bezel 50. The angled bezel 50 has a similar construction as angled bezels 10 and 40. The angled bezel 50 is designed to receive a single connector and thus is approximately half the width of the bezels 10 and 40. The icon holding grooves 30 and 32 receive a single icon. The opening 52 in angled bezel 50 receives a single F-type coaxial connector to form a simplex F-type port.

FIGURES 10-12 are respective front, side and perspective views of an alternative angled bezel 60. The angled bezel 60 is similar to the angled bezel 50 in that there is only one opening 62 in the body 12. The opening 62 in angled bezel 60 receives a single ST-type connector to form a simplex ST-type port.

FIGURES 13-15 are respective front, side and perspective views of an alternative angled bezel 70. The angled bezel 70 is similar to the angled bezel 60 in that there is only one opening 62 in the body 12. The opening 72 in angled bezel 70 receives a single RCA-type connector to form a simplex RCA-type port.

FIGURE 16 is a front view of a flat bezel 80. As shown in FIGURE 17, the flat bezel 80 includes top notches 16 and bottom notches 18. The top notches 16 have curved surfaces 20 and 22 adjacent to the opening of each notch 16. The bottom notches 18 also have curved surfaces 24 and 26 adjacent to the opening of each notch

18. As previously described, the curved surfaces ease mounting the flat bezel in a panel cut-out from either side of the panel.

The body 83 of the flat bezel 80 is in a different orientation than the angled bezels shown in FIGURES 1-15. As previously described, the notches 16 and 18 define a plane corresponding to the plane of the cut-out in the panel. The body 83 is substantially parallel to this plane. A pair of icon holding grooves 84 and 86 are included in the flat bezel 80. The first icon holding groove 84 is formed on the body section 83. The second icon holding groove 86 is formed near the top notches 16 at one end of resilient section 88.

To mount the flat bezel 80 in the panel cut-out, a similar procedure is followed as described above. The bottom notches 18 are placed in the panel and engage the edge of the panel cut-out. The flat bezel 80 is then pressed towards the panel. The curved surfaces 20 or 22 contact the edge of the panel cut-out and flex the top notches 16 towards the body 83. Once the curved surface 20 or 22 clears the edge of the panel, the top notches 16 snap around the edge of the panel cut-out.

An important feature of the flat bezel 80 is that the icon serves as a lock to prevent the resilient section 88 from flexing. When an icon is placed in grooves 84 and 86, the top notches 16 are prevented from moving towards the body 83 due to the height of the icon. Until the icon is removed, the notches 16 and 18 cannot become disengaged from the edge of the panel cut-out. Thus, the flat bezel 80 is securely locked in place.

The body 83 includes an opening 82 for receiving a connector. In the flat bezel 80 shown in FIGURE 16, the opening 82 receives a single ST-type fiber optic connector to provide a simplex ST-type port.

FIGURES 19-21 are respective front, side and perspective views of an alternative flat bezel 90. The flat bezel 90 is similar to flat bezel 80 shown in FIGURES 16-18. Flat bezel 90 has an opening 92 formed in body 83 for receiving a single BNC-type coaxial connector to provide a simplex BNC-type port. FIGURES 22-24 are respective front, side and perspective views of an alternative flat bezel 100. The flat bezel 100 is similar to flat bezel 80 shown in FIGURES 16-18. Flat bezel 100 has an opening 102 formed in body 83 for receiving a single RCA-type coaxial connector to provide a simplex RCA-type port. FIGURES 25-27 are respective front, side and perspective views of an alternative flat bezel 110. The flat bezel 110 is similar to flat bezel 80 shown in FIGURES 16-18. Flat bezel 110 has an opening 1 12 formed in body 83 for receiving a single F-type coaxial connector to provide a simplex F-type port. FIGURES 28-30 are respective front, side and perspective views of an alternative flat bezel 120. The flat bezel 120 is similar to flat bezel 80 shown in FIGURES 16-18. However, the flat bezel 110 is approximately twice as wide as the flat bezel 80. This increase in width is to provide space for two openings 122 in body 83. In addition, the flat bezel 120 can receive two icons for identifying each port. Flat bezel 120 has openings 122 formed in body 83 for receiving two ST-type fiber optic connectors to provide a duplex ST-type port.

FIGURES 31-33 are respective front, side and perspective views of an alternative flat bezel 130. The flat bezel 130 is similar to flat bezel 120 shown in FIGURES 28-30. Flat bezel 130 has an opening 132 formed in body 83 for receiving a duplex SC-type fiber optic connector to provide a duplex SC-type port.

The multimedia bezels described above are all side stackable. The side surfaces of each of the bezels is planar and abuts flush against adjacent bezels in the panel cutout leaving no gap between the respective bezels. This allows the configuration of bezels in a panel cut-out to be varied with ease. For example, a panel cut-out sized to receive two duplex bezels could also receive four simplex bezels with no gaps between the individual bezels or the panel cut-out edge and the bezels. Accordingly, the arrangement of bezels in the panel cut-out can be easily modified.

The multimedia bezels of the present invention provide a convenient mechanism for altering the connection type in a panel without the need to replace the existing panel. The bezels are sized to fit a standard panel cut-out making conversion from one connection type to another easy. The bezels have both angled and flat configurations and thus are suitable for a variety of cable routing applications. While preferred embodiments have been shown and described, various modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustration and not limitation. What is claimed is:
