Description




BACKGROUND OF THE DISCLOSURE




1. Technical Field




The present disclosure relates to devices for interfacing with high frequency data transfer media and, more particularly, to a terminal block having a system and method for identifying the transfer media associated therewith.




2. Background Art




Standard commercially available, terminal blocks, including the commonly used 110-style block, are typically used to provide an interconnection between electronic equipment and work area outlets for electrically conductive data transfer media (hereinafter also referred to as “cable”), such as unshielded twisted pair cable (“UTP”). UTP is a popular and widely used type of data transfer media for either voice or data communications. In fact, UTP is rapidly becoming the de facto standard for Local Area Networks (“LANs”) and other in-building voice and data communications applications.




The termination is actually a joining of two cables with the block acting as a transfer point. The block is dielectric and does not have metallic contacts. However, the block provides a plurality of termination locations (hereinafter also referred to as “terminals”) which have engagements for securing the individual signal-carrying elements (hereinafter also referred to as “wires”) from a plurality of cables. The connection between the terminated cable and a second cable is typically facilitated by terminal clips having electrically conductive contacts and a set of engagements for the second cable wires. The block and clips arrangement (collectively referred to as the “terminal block” or “punchdown system”) allows interchangeable interconnection of the wires, thus making wiring and rewiring the block easier. The block and clips are configured to have corresponding fittings so that the clips can be non-permanently affixed to the terminals on the block.




Typical applications, such as telephone service, for both business and residential sites, require a substantially large amount of cables for connecting incoming and outgoing wires. These cables will be terminated at a plurality of blocks, usually for routing purposes. When dealing with many cables in a situation like this in the field, it is imperative that every cable be labeled or otherwise identified at each termination point.




Referring initially to

FIG. 1

, which illustrates a prior system of identification for cables connected with a standard block


12


and plurality of terminal clips


22


, it is clear that the prior system provides a limited amount of labeling space. Furthermore, the prior system is fitted onto block


12


but not secured. A great deal of time would be wasted by technicians determining cable destinations should the prior system for identifying cables be dislodged.




Also, in view of increasing demands being placed on communication systems (e.g., the implementation of category 6 standards), many new devices and/or methodologies for reducing electrical noise associated with communication equipment are being employed. Some of these improvements may alter the design of the blocks or clips which can, in turn, hamper or possibly inhibit use of the prior system and/or any similar systems.




Consequently, there exists a need for a system and method for identifying cables associated with a terminal block which is more reliable, in that it is secured to the block and not likely to fall off or be accidentally removed, and compatible or adaptable to new devices used in conjunction with the block. These and other objectives are achieved through the advantageous system and method disclosed herein.




SUMMARY OF THE DISCLOSURE




The present disclosure provides an identification system which includes an identification bar and retainer clips for securing the identification bar. The retainer clips may include flags.




Furthermore, the present disclosure is directed to an identification system for signal carrying media associated with a terminal block. The block has a plurality of laterally adjacent rows of terminals for connecting media which also define recessed channels therebetween. The identification system includes an elongated member adapted to be seated within one of the recessed channels and a structure or means for securing the elongated member within the recessed channel.




The elongated member includes a plurality of locations for communicating information relating to the media associated with the terminal block. The information may be communicated by directly writing on the elongated member. Alternatively, an elongated label adapted to fit the elongated member may be slipped under the elongated member (if the elongated member is translucent) prior to being secured on the terminal block. Also, the labels may be made of paper and include adhesive on one side for being adhered to the elongated member. The labels may be preprinted or written on in the field. Preferably, the elongated member includes a planar surface for receiving the labels or any indicia relating to the media associated with the terminal block. Preferably, the elongated member has a substantially planar upper surface and its opposed longitudinal sides are folded down and substantially inward toward each other.




In an embodiment of a system in accordance with the present disclosure, a retaining member having an engagement portion for mechanically engaging the terminal block is used to secure the elongated member. The retaining member may also define a plurality of locations for communicating information, such as information relating to the destination of the media associated with the terminal block. These locations may be on a separate component attachable to the terminal block but preferably are defined on the retaining member. Preferably, the retaining member has slots for securing the labels thereto. The engagement portion may include a latching device for connecting the retaining member with the terminal block and/or a slot for receiving a portion of the terminal block.




The identification system may be made of metal or a dielectric material, such as wood or polymer. The identification system can be advantageously fabricated of extruded, die-cut or injection-molded plastic.




The present disclosure is also directed to a terminal block comprising a dielectric support member including laterally adjacent rows of terminals used to facilitate electrical coupling between cables which define recessed channels therebetween. The terminal block further includes an elongated member with locations for communicating information relating to the cables and a structure or means operatively associated with the terminal block for securing the elongated member in a recessed channel. Preferably, the securing structure or means includes locations for communicating information relating to the cables coupled on the terminal block.




In one embodiment of the aforementioned system, the elongated member is secured by a retaining member having an engagement portion for engaging the terminal block.




The present disclosure is further directed to a method for identifying media associated with a terminal block. The steps in this method include positioning an elongated member within a recessed channel defined on the block, wherein the elongated member defines a plurality of locations for communicating information relating to the media associated with the terminal block, and securing the elongated member in the recessed channel with a retaining member. Preferably, the retaining member is supported in position for securing the elongated member by being attached to the block. The method can also include the step of affixing labels to the elongated member.




These and other unique features of the systems, devices and methods of the present disclosure will become more readily apparent from the following description of the drawings taken in conjunction with the detailed description.

Referring now to

FIGS. 2 and 3

, identification system


10


includes an elongated member


36


and retaining members


38


. Elongated member


36


is dimensioned to fit at least partially within channels


16


and


18


, and retaining members


38


are configured to secure elongated member


36


therein. Preferably, retaining members

As indicated by the arrows in

FIG. 2

, elongated member


36


is placed in channel


16


and two retaining members


38


are connected with the ribs


20


corresponding to rows


14




a


and


14




b


after the media is terminated on block


12


with clips


134


. Notches


56


engage the corresponding laterally adjacent protuberances


32


and slots


60


receive at least a portion of protuberances


30


, thus securing retaining members


38


to block


12


. Also, once retaining members


38


are secured as described above, the distal end of central latches


54


contacts the upper surface


42


of elongated member


36


, thus securing elongated member


36


in channel


16


. Labels


40


and


50


, which may include adhesive strips with removable backings can be disposed onto elongated member


36


and retaining members


38


. Labels


40


and


50

illustrates an alternative embodiment constructed in accordance with the present disclosure generally indicated by the reference character


110


. In this embodiment, two blocks


112


without support legs are placed end-to-end, as is a standard practice in the field. Elongated member


136


is disposed in channel


116


much like in the previous embodiment. However, channel


116


extends the length of the two blocks


112


and elongated member


136


is elongated to fit channel


116


accordingly.




Preferably, identification system


10


and


110


are fabricated from a suitable dielectric material, such as, for example, a polymer or plastic. However, elongated member


36


and retaining member


38


may be made of wood or metal. Preferably, elongated member


36


or


136


is translucent and shaped, as shown in

FIGS. 2 and 4

, so that its opposed longitudinal sides are folded-in, thus creating an elongated slot therebetween, which, among other things, provides for a better fit in the channel and a secure location for a label to be positioned prior to installation. Also, elongated member


36


is preferably made of a slightly resilient plastic, while retaining member


38


is preferably made of a more rigid plastic material. Identification system


10


and


110


may be constructed via extrusion, injection molding, die-cut or other conventional techniques. Label covers


52


are preferably clear and may be made of mylar.




Although the disclosed systems, devices and methods have been described with respect to preferred embodiments, it is apparent that modifications and changes can be made thereto without departing from the spirit and scope of the invention as defined by the appended claims.
