Description

Mounting brackets for IDC connection modules

technical field

The invention relates to a mounting bracket for an IDC connection module.

Background technique

Long-distance communication and data systems often require "patch code" connections to connect input and output cables. For this purpose, connection modules are available. Many connection modules provide connections for input and output cables on one side of the module and connections for patch code lines on the other side. The connection module can use different methods to make the electrical connection of the cable and the patch code line, but the common application is the insulation-displacement type ("IDC") or "wire covered" type connector. Many of these modules may be required to provide the required connections within the distribution system, and as such, the connection modules must be organized and contained on a rack or frame in a compact and efficient arrangement. Various devices or mounting brackets have been developed to mount the connection modules to racks or frames used in telecommunications distribution systems. For example, DE 298 07 669 U1, DE 299 03 640 U1, DE 197 10 000 C1, U.S. Pat. 5,595,507 and DE 38 13 078 A1 describe various mounting brackets suitable for mounting several types of IDC connection modules. DE 8914 909 U1 describes a bracket for wire-wrapped connectors.

Contents of the invention

The present invention provides a mounting bracket suitable for mounting an IDC connection module on a mounting rail for a long-distance communication bay or frame, the mounting bracket comprising: (a) a holder for holding one or more IDC connection modules bracket, (b) at least one lateral positioning member for positioning the bracket in a desired lateral orientation relative to the mounting rail, and (c) at least one removable fixing member provided by one or more fixing devices Removable attachment of the mounting bracket to the mounting rail, the securing means configured to permit attachment to one or more complementary components on the mounting rail.

The invention also provides a telecommunications bent rack comprising one or more mounting brackets according to the invention.

A bracket for holding one or more IDC connection modules is adapted to mount the IDC connection modules. Various configurations of the bracket are possible, for example one useful configuration of the bracket is a channel member having a base, two side wall sections and two open end sections. The side walls of such a structure may be solid (for example, by bending sheet metal to form the walls), or the walls may have a more open structure such as a frame shape. For example, a frame shape may include a horizontal top rail, two vertical side rails each connected to the bottom of the frame. The bottom of the bracket can also be solid or a more open structure. In general, the side walls are preferably of a more open configuration to allow for a more economical construction material and for simple and neat insertion of the cables (and their wires) from the side into the IDC connection module. Various compartments may be provided along the side wall sections for latching or mounting IDC connection modules. For example, an edge depending from above, a notch or opening positioned along the top of a side wall portion can be used to complementarily communicate with a latch, hook or other component, for example, to secure them on an IDC connection block (typically a detachable) to the mounting bracket.

The lateral positioners are configured to position the mounting bracket in a desired lateral orientation relative to the mounting rail. The lateral positioners limit tilting of the mounting bracket from its ideal lateral orientation to the mounting rail, such as might occur, for example, if a force is exerted on the mounting bracket. Accordingly, the lateral locators are preferably configured to complementarily fit within a socket, or to fit relatively tightly around at least a portion of the mounting rail, to help prevent the locators from rotating or tilting relative to the rail.

For example, in one embodiment, the lateral positioner includes a slot configured to receive a leg on at least one mounting rail. Typically, such legs protrude towards the front of the mounting rail (ie, the direction is the same as the front of the mounting bay when the mounting rail is mounted on the mounting bay). In such embodiments, the width of the slot is at least sufficient to accommodate the width of the protruding legs, while the depth of the slot can be readily selected for a particular embodiment to facilitate maintaining the lateral orientation of the mounting bracket. In a preferred embodiment, the mounting bracket of the present invention has two lateral locators, each having a slot configured to receive a single protruding leg of the mounting rail.

The bracket (a) and the lateral positioning member (b) and the detachable fixing member (c) may be separate independent parts of the mounting bracket, which are all connected together to form the mounting bracket. Preferably, however, the bracket (a) and the transverse positioner (b) form a unitary structure, whereas the detachable fixing is a separate component mounted on the unitary structure (bracket and transverse positioner).

In each case, however, the detachable fixing communicates with the bottom of the bracket, on the side opposite the side wall. Preferably, the detachable mount extends from the bottom of the stand in a direction substantially perpendicular to the plane of the bottom of the stand. The detachable fixing member preferably also communicates with the bottom of the frame along its entire length (when the frame is configured as a channel).

Various means can be used to attach the removable fasteners to the other components of the mounting bracket, but the traditional construction using sheet metal is preferred. Particularly preferred are connection means that provide good electrical communication between the bracket and the lateral positioning members and removable fixing members. Non-limiting examples of useful connectors include screws, bolts and nuts, locking tabs, hooks, pins, rivets, adhesives and latches.

The removable mount includes one or more mounts configured to attach to complementary components on the mounting rail to mount the mounting bracket to the mounting rail. The mounting rail may have apertures, recesses and/or protrusions along its surface which may serve as complementary parts for attaching the mounting bracket by means of fastening means of the detachable fixing. Some fixing means may be latching means, which form a latching connection with the mounting rail. For example, one or more protrusions on the removable mount may mate with one or more complementary openings (eg, holes) in the mounting rail, or recesses (eg, notches or hollows) in the closed end , to form a latched connection. Of course, the reverse configuration can also be used. Additional fixing means may also be used, eg nuts, to secure the connection of the removable fixing to the mounting rail when a latch connection is used. For example, a removable mount with a hole may mate with a complementary component on the mounting rail, such as a stud or bolt. In this case, additional fixing means such as nuts can be screwed onto the nuts to secure the connection of the mounting bracket to the mounting rail.

Furthermore, the removable mount and mounting rail may each be configured with one or more complementary apertures. In this case, additional, separate connection means, such as screws, nuts and bolts, studs and pins, may be used to secure the connection between the removable fixing and the mounting rail. For example, a screw can be inserted into an opening in the removable mount and screwed into a threaded hole in the mounting rail to form a secure connection.

Certain bays, such as those used with wire-wrapped connectors, may have small protrusions (eg, stubs) that protrude along the surface perpendicular to the protruding legs of the mounting rail. Typically, such protrusions are only a few millimeters long. The removable mount may be configured with one or more open-ended notches, each opening to an edge of the removable mount. Such a configuration allows the part to "slide" the stud (or other complementary protrusion) into the notch. The notches can also be sized on the removable mount such that each notch accommodates only one stud. It may be more useful to configure such an open-ended notch as a funnel-like shape. Such a notch may be formed or cut on the removable mount from the edge of the mount with the open end wider than the closed end, the recess tapering in width from the open end to the closed end. Optimally, the width of the closed end of the notch is about the same as the width of the protrusion, thereby providing a tight fit between the protrusion and the notch and stabilizing the orientation of the mounting bracket on the mounting rail (especially in the longitudinal direction). direction). It is particularly preferred to provide two such open-ended recesses in a spaced arrangement on the detachable fixing member, so that they form a longitudinal positioning with respect to each other. The length of the longitudinal positioning portion is preferably approximately equal to the distance between two adjacent studs on the mounting rail. The detachable fixing part of this structure improves the stability of the longitudinal positioning of the mounting bracket on the mounting rail.

When using a latch between the removable mount and the mounting rail (i.e., using a protrusion and a hole or notch at the closed end), it is best to position the latch on the removable mount in a A portion of a detachable mount that is substantially flexible or movable relative to the remainder of the detachable mount, thereby allowing the latch to more easily bend or move away from its complementary component on the mounting rail . One way to provide a relatively flexible portion of the latch is to locate it on a leg or tab cut from the rest of the removable fastener.

A removable fastener comprising two spaced apart open-ended notches, and at least two other latching fasteners, each on a leg or tab, is particularly preferred. In such an embodiment, the open-ended notch opens on the edge of the removable mount opposite the connection point of the bottom of the bracket. When mounted on the mounting rail, the two notches surround two spaced apart protrusions (ie stubs) on the rail, thereby further stabilizing the orientation of the mounting bracket along the length of the mounting rail. The latching fixture engages its complementary component on the mounting rail to further secure the mounting bracket to the mounting rail and to limit movement of the bracket toward the "front" direction of the mounting rail.

Combinations of various types of fixtures can be used on a single removable fixture to construct a mounting rail with a combination of complementary components, such as studs, notches and holes.

It is particularly preferred to provide a mounting bracket with fastening portions which can be punched from one or more side walls of the bracket and are configured to connect the shield end and the cable tie.

In a preferred embodiment of the invention for a bent rack with a single mounting rail system (such as the system already indicated for mounting wire-wrapped connectors), the mounting bracket comprises a Brackets for wall sections. Disposed on each open side portion of the bracket is a lateral positioning member. The bracket and lateral spacers are formed from a single piece of material such as sheet metal, with the lateral spacers configured (e.g., by cutting) in the shape of flaps or tabs that bend downward from the bottom of the bracket in the direction opposite the side walls fold. Preferably, the tabs or flaps are bent straight down so that they form approximately a 90 degree angle with the bottom of the bracket, although other angles may be used. Each lateral positioner is provided with a slot configured to receive a protruding leg of the mounting rail.

The present invention, for the first time, enables IDC modules to be mounted on bent racks for wire-wrapped connections, thereby significantly increasing the flexibility of such telecommunications distribution devices (eg, main distribution frames). Wire-wrapped telecommunications distribution units typically have a bent shelf that includes "L" shaped rails. The main projecting leg of the "L" shaped rail generally protrudes in a direction towards the front of the bent shelf and extends along the longitudinal length of the rail. A mounting bracket comprising at least one lateral locator with a slot conveniently accommodates the front protruding leg of the "L" shaped rail. Therefore, when changing from a wire-wrap type connector to an IDC connector in a distribution device, it is not necessary to change the mounting bay. On the contrary, the present invention can be used to install IDC connection modules in the original wire-wrapped connector bays.

Brief description of the drawings

The present invention is further described by a preferred embodiment as shown in the accompanying drawings, wherein:

Figure 1 is an exploded perspective view of the mounting bracket of the present invention; and

2 is a perspective view of the mounting bracket of the present invention including the IDC connection module mounted on a wire-wrapped bracket mounting rail.

Detailed ways

Referring now to Figure 1, a preferred embodiment of the mounting bracket 10 of the present invention is shown. The mounting bracket 10 is constructed in two parts, including a bracket 14 and a detachable fixing part 12 . The two parts are interconnected by a rivet 16 which passes through an opening in the bottom 18 of the bracket and an opening in an angled flange 20 in the removable fixing. In order to realize the connection between the detachable fixing part 12 and the bracket 14 , the detachable fixing part further includes two tabs 22 extending along the direction of the bracket 14 , and each tab is provided with an opening 24 . The base 18 of the support has two U-shaped recesses 26 at corresponding points, each with a lug 28 . When the bracket is mounted on the detachable mount, tabs 28 engage in openings 24 in tabs 22 on the detachable mount, thereby mounting the bracket to the detachable mount.

As can also be seen in Figure 1, the removable mount 12 includes a longitudinal positioning portion 30 integrally formed from the sheet metal of the removable mount. The longitudinal positioning portion 30 includes two notches 32, each configured as an open-ended slot. Recesses 32 are "funnel-shaped", each comprising an open insertion portion that tapers to a narrower end. The width of the ends is adapted to fit the diameter of the stub on the mounting rail 46 for the wire-wrapped bracket (see FIG. 2 ). FIG. 2 shows how the mounting bracket 10 can be positioned in the longitudinal direction of the mounting rail 46 by using the longitudinal positioning portion 30 and the stud 64 on the mounting rail 46 . Each notch 32 is positioned on the mounting rail 46 so that it receives the post 64, and the mounting bracket 10 is then advanced toward the rear or back of the mounting rail 46, thereby seating each post in the narrow space of the notch 32. inside the end. Such displacement sets the height of the mounting bracket 10 at its desired final mounting position (when the mounting rails 46 are vertically aligned).

Preventing the mounting bracket 10 from moving undesirably towards the front side of the mounting rail 46 (or mounting bracket) is accomplished by two latching tabs 34, each constructed on one of the side edges of the removable fixture 12. on the side. By providing a groove 36 between each latch tab 34 and the remainder of the removable fastener, the latch tab 34 is sufficiently soft relative to the remainder of the removable fastener to allow a protrusion 38 (as shown in FIG. 1 ). shown configured on the rear of the removable mount) engages and disengages with a corresponding opening or notch on the mounting rail 46 (see also FIG. 2 ).

The aforementioned components enable the positioning of the mounting bracket 10 in the longitudinal direction of the mounting rail while reliably preventing unwanted movement towards the front side of the mounting rail and allowing the mounting bracket to be detached from the mounting rail.

In the illustrated embodiment, lateral positioners 40 are provided to maintain the lateral orientation of mounting bracket 10 on mounting rail 46 and to limit or constrain tilting of the bracket when mounted on mounting rail 46 . In the illustrated embodiment, lateral positioners 40 are disposed on opposite sides of the bracket base 18 . They curve downward (eg, by bending) from the bracket bottom 18 in the opposite direction to the side walls 48 of the mounting bracket. Each lateral positioning member includes a slot 42 . The forwardly projecting legs 44 of the mounting rail are received in the slots 42 such that the mounting bracket 10 can be positioned in a transverse orientation relative to the mounting rail 46 . This orientation defines the lateral positioning of the mounting bracket 10 .

In addition to the frame base 18 , the mounting frame 14 also includes two side walls 48 which are formed as a frame. The upper edge of each frame includes openings 50 suitable for latching or attaching latching means to conventional IDC connection blocks, thereby making side walls 48 suitable for mounting IDC connection modules.

The embodiment of FIG. 1 preferably provides material savings and a fully fitted mounting bracket by die-cutting two fixing portions 52 from each side wall 48 (only one such fixing portion 52 is shown in FIG. 1 ). The fixed portion 52 curves downward (eg, by bending) from the plane of the side wall 48 toward the bottom of the mounting bracket. Each securing portion 52 includes openings 54 for latching shield ends shielding the exposed braided shielded cable. Furthermore, the cables leading to the IDC connection modules mounted on the mounting bracket 10 are terminated on "T" shaped webs 56 provided in correspondingly configured recesses 58 by means of cable ties. Preferably, the "bending down" (or kink) of the securing portion 52 is limited to an angle of less than 90 degrees relative to the plane of the bracket bottom 18 .

FIG. 2 shows how to install the IDC connection module configured as a connection block 60 on the installation rail 46 using the installation bracket 10 . As noted above, the side walls 48 of the mounting bracket 10 are adapted to mount a number of connection blocks 60 (on the front side of the mounting bracket 10 when mounted on the mounting rail 46). The mounting bracket 10 is mounted on a mounting rail 46, which includes a forwardly extending leg 44 (extends to the front of the mounting rail when the rail is mounted on the wire-wrapped bracket), and another leg 62 (to The vertical angle extends from the forwardly extending leg 44). The legs 62 are used to mount the mounting rail 46 on the wire-wrapped bracket. The mounting bracket 10 can be combined with certain components of the mounting rail 46 so that it can mount the IDC connection block 60 on a wire-wrapped type bracket. Several studs 64 are arranged at regular intervals along the longitudinal direction of the mounting rail 46 . The notches 32 on each side of the longitudinal positioning portion 30 are spaced from each other by a sufficient distance to accommodate two regularly spaced posts 64 . A post 64 is received by a notch 32, thereby eliminating the possibility that the mounting bracket 10 may be displaced in the longitudinal direction of the mounting rail 46 (ie, as shown in FIG. 2, up and down). In addition, the latching tabs 34 are shaped and spaced (spaced apart) so that their projections 38 latch into openings or notches 66 located at the rear of the legs 44 of the mounting rail 46 . In addition, a flange 68 with an aperture 70 is provided on each latch tab 34 to provide an easy entry point for engaging the latch tab 34 so that it can be bent slightly to the right to allow the protrusion 38 escapes from the notch 66, thereby enabling the mounting bracket 10 to be easily removed from the front side of the mounting bracket.

Overall, a defined lateral structural arrangement of the mounting bracket 10 relative to the mounting rail on the mounting bay is achieved by means of the lateral positioning section 40 , also referred to as "guide stop". This is accomplished by locating the front extending leg 44 in the slot 42 of the lateral positioning portion 40 .

Therefore, the present invention describes a mounting bracket 10 suitable for mounting an IDC connection module 60, which includes at least one rear positioning portion 40 that positions the mounting bracket 10 in a lateral direction relative to the mounting rail 46, and at least one rear positioning portion 40 positioned behind the mounting bracket 10. The detachable fixing member 34 of the part is configured to provide a detachable connection with the complementary positioning device 66 on the mounting rail 46, so that the mounting bracket 10 can be installed in a position including the notch 66 and/or Bores and/or holes and/or studs 64 are mounted on rail 46 .

Preferably, the rear positioning portion for positioning the mounting bracket 10 in the lateral direction is oriented substantially perpendicular to the bottom 18 of the mounting bracket 10 .

According to one embodiment of the present invention, the rear positioning portion 40 for positioning the mounting bracket 10 in a transverse direction relative to the mounting rail includes a slot 42 for receiving the mounting rail 46 .

The present invention also describes a mounting bracket in which a rear longitudinal positioning portion 30 extending substantially perpendicular to said transverse positioning portion 40 is provided, said longitudinal positioning portion 30 preferably comprising at least one Notch 32 of post 64 on rail 46 .

Preferably, said notch 32 for positioning said stud 64 is configured in the form of a slot, preferably with an open insertion portion.

According to another embodiment of the invention, the fixing means of the mounting bracket 10 is a bore or hole adapted to receive a screw or a bolt.

The present invention also describes a mounting bracket wherein the removable securing means is at least one latching means 34 configured to latch on the mounting rail 46 with a complementary latching means 66 .
