## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates the mounting arrangement between a face panel and modular jacks and more particular, to a multidirectional modular jack and face panel mounting structure, which allows modular jacks to be installed respective mounting through holes of a face panel in one of a series of angular positions.
2. Description of the Related Art
When arranging a local area network in a building, optical fiber cables or electrical cables are extended from a server room in the building to modular jacks in the walls at different rooms and different floors of the building so that computers in each room of the building can be connected to the adjacent modular jacks by modular plugs of computer cables.
In the server room, racks are installed to support network switches, servers and other devices. The servers in one rack are electrically connected to a face panel of the respective rack. The face panels of all racks in the server room are electrically connected by network cables.
However, with increase in office business and office personnel and rapid development of network communication technology, some problems may follow. The existing capacity of the network equipment in the server room may be insufficient to meet the needs of the company. However, adding extra network equipment to expand the capacity requires much server room installation space. Using small sized network equipment can save server room space.
When installing multiple network equipments in a limited server room, patch cords may have to be bent into a curved condition to reduce space occupation. However, a large angle bending of patch cords may break the core wires.
To avoid over-bending of patch cords U.S. Pat. No. 6,866,541 discloses an angled patch panel with cable support bar for network cable racks. According to this design, the patch panel includes a patch panel frame and rack mounting plates. The frame forms a central section having a longitudinal width sized to fit within the network rack. The rack mounting plates are provided on opposite longitudinal ends of the central section and allow the panel to be mounted to a network rack. The central section includes two panel sections angled outwardly in an inverted V-shapes, and the central section has mounted thereon a plurality of cable connectors that receive cabling on the front side and the rear side of the patch panel frame. Each connector has a horizontal axis. According to this design, angled patch panel simply allows module jacks to be arranged at right angles. When connecting module plugs of network cables to the module jacks at the angled patch panel, the network cables can simply be extended in two directions. Further, a server rack fitting the angled patch panel must be designed having an extended depth, increasing space occupation. Therefore, this design is not conducive for high-density installation.
U.S. Pat. No. 7,762,839 discloses a patch panel assembly including an angle module having one or more RJ modules, one or more insulation displacement contact (IDC) modules and a printed circuit board. According to this design, all RJ modules keep the plug receiving holes thereof in one same direction after installation. When connecting RJ plugs of network cables from different directions to the RJ modules, the extending directions of the network cables have to be changed to fit the extending direction of the plug receiving holes of the RJ modules.

Referring to FIG. 1, a multidirectional modular jack and face panel mounting structure in accordance with the present invention is shown comprising a face panel 10, and a plurality of modular jacks 20 mounted in the face panel 10 in a row.
Referring to FIGS. 2, 3 and 4, the face panel 10 comprises a front face layer 101 made of a metal material, and a back lining layer 11 made out of a plastic material using a molding technique and fixedly attached to the back side of the front face layer 101. In this embodiment, the front face layer 101 of the face panel 10 is punched to provide an elongated slot 12. The back lining layer 11 comprises a row of equally spaced window openings 13 corresponding to the elongated slot 12 of the front face layer 101 for receiving the modular jacks 20 that extend in F-R direction (see FIG. 2), and a plurality of modular jack engagement structures for securing the modular jacks 20 in the respective window openings 13 and the elongated slot 12. The window openings 13 and the elongated slot 12 are combined together, forming a plurality of modular jack mounting holes. Further, each modular jack engagement structure comprises opposing top and bottom hook rods 14 and 15 respectively perpendicularly extended from the back wall of the back lining layer 11 at top and bottom sides of each respective window opening 13.
Each modular jack 20 comprises an IDC (Insulation Displacement Connection) housing 21, an IDC terminal block (not shown) mounted in the IDC housing 21, a plurality of IDC terminals (not shown) mounted in the IDC terminal block and respectively electrically connected with respective core wires of a network cable (not shown). The cross section of the IDC housing 21 is configured to fit the combined shape of each window opening 13 and the elongated slot 12. In this embodiment, the IDC housings 21 of the modular jacks 20 and the window opening 13 have a rectangular cross section. However, this configuration is simply an example but not a limitation.
As shown in FIG. 5, the IDC housings 21 of the modular jacks 20 can made having a square cross section; the window openings 13 can star shaped, each formed of two square holes 13a and 13b that are overlapped together and biased at a 45 degree angle relative to each other. Thus, there are 8 installation directions for selection. Alternatively, the IDC housings 21 of the modular jacks 20 can made having a rectangular cross section; the window openings 13 can be respectively formed of two rectangular holes 13c and 13d that extend across each other at right angles. In general, the IDC housings 21 of the modular jacks 20 can made in a square shape, rectangular shape, circular shape or any of a variety of other geometric shapes, and the window openings 13 can be formed of two openings that are overlapped together and biased relative to each other at a predetermined angle for accommodating the IDC housings 21 of the modular jacks 20 in one of a series of angular positions.
Referring to FIGS. 6 and 7, the IDC housing 21 of each modular jack 20 defines a tilted modular plug insertion hole 22 at the front side thereof. After installation of one modular jack 20 in one respective window opening 13 of the back lining layer 11 and the elongated slot 12 of the front face layer 101 of the face panel 10, the tilted modular plug insertion hole 22 of the installed modular jack 20 is exposed to the outside the face panel 10 for the insertion of a modular plug (not shown). The so-called “tilted” means that the tilted modular plug insertion hole 22 is not at the vertical line V, it defines with the horizontal line H a predetermined contained angle θ.
Further, in this embodiment, the IDC housing 21 of each modular jack 20 comprises opposing top and bottom walls and two opposing sidewalls, two first hook grooves 23 respectively located at the opposing top and bottom walls thereof, and two second hook grooves 24 respectively located at the opposing sidewalls thereof.
That is, the IDC housing 21 of each modular jack 20 comprises a face panel engagement structure disposed between the front side F (in direction toward the face panel) and rear side R (opposite to the front side) thereof for engagement with one modular jack engagement structure of the face panel 10. Further, the IDC housing 21 defines a first axial direction extending from its front side toward its rear side (in parallel to the horizontal line H), and a second axial direction extending along the tilted modular plug insertion hole 22 and defining with the first axial direction a contained angle.
Referring to FIG. 8 and FIGS. 6 and 7 again, the IDC housings 21 of the modular jacks 20 can be selectively mounted in the window openings 13 of the back lining layer 11 and the elongated slot 12 of the front face layer 101 of the face panel 10 in one of a series of angular positions for enabling respective mating modular plugs 90 to be inserted into the tilted modular plug insertion hole 22 of the modular jacks 20 in the face panel 10 at different angles. For example, the IDC housing 21 of each modular jack 20 can be selectively mounted in one window opening 13 of the back lining layer 11 and the elongated slot 12 of the front face layer 101 of the face panel 10 in a first position where the IDC housing 21 has its top wall facing down, its bottom wall facing up and its first hook grooves 23 respectively kept in engagement with the opposing top and bottom hook rods 14 and 15 of the respective modular jack engagement structure and the tilted modular plug insertion hole 221 kept extending obliquely upward, or in a second position biased from the first position at 90-degree angle where the IDC housing 21 has its opposing top wall facing leftward and its bottom wall facing rightward and its second hook grooves 24 respectively kept in engagement with the opposing top and bottom hook rods 14 and 15 of the respective modular jack engagement structure and the tilted modular plug insertion hole 223 kept extending obliquely leftward, or in a third position biased from the second position at 90-degree angle where the IDC housing 21 has its opposing top wall facing down and its bottom wall facing up and its first hook grooves 23 respectively kept in engagement with the opposing top and bottom hook rods 14 and 15 of the respective modular jack engagement structure and the tilted modular plug insertion hole 222 kept extending obliquely downward, or in a fourth position biased from the third position at 90-degree angle where the IDC housing 21 has its opposing top wall facing rightward and its bottom wall facing left wall and its second hook grooves 24 respectively kept in engagement with the opposing top and bottom hook rods 14 and 15 of the respective modular jack engagement structure and the tilted modular plug insertion hole 224 kept extending obliquely rightward. If the IDC housings 21 of the modular jacks 20 are made having a square cross section and the window openings 13 are star shaped and respectively formed of two square holes 13a and 13b that are overlapped together and biased at a 45 degree angle relative to each other, as shown in FIG. 5, the modular jacks 20 can be installed in the face panel 11 in one of a large number of angular positions.
In an alternate form of the present invention, as shown in FIG. 9, the multidirectional modular jack and face panel mounting structure comprises a face panel 100, and a plurality of modular jacks 200 mounted in the face panel 100 in a row. This alternate form is substantially similar to that shown in FIGS. 1-8 with the exception that the window openings 130 of the face panel 100 are composite window openings; the IDC housing 210 of each modular jack 200 comprises a plurality of retaining blocks 211 located at opposing top and bottom walls thereof, and two transverse locating ribs 212 respectively located at two opposing sidewalls thereof.
When mounting the IDC housing 210 of one modular jack 200 in one composite window opening 130 of the back lining layer 110 of the face panel 100, the retaining blocks 211 are forced into engagement with the outer surface of the back lining layer 110 around the composite window opening 130, and the transverse locating ribs 212 are stopped at the inner surface of the back lining layer 110 around the composite window opening 130 (see FIG. 10).
In conclusion, the invention allows the user to install the modular jacks in the face panel in one of a series of angular positions to keep the tilted modular plug insertion holes of the respective modular jacks in different directions for the installation of respective mating modular plugs in different directions. When the invention is used in a network equipment, all the network cables can be properly arranged in different directions, avoiding network cable damage or tangled network cables.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
