BY 4%, $41M ATTORNEYS BACKGROUND OF THE INVENTION The assembly in question is adapted for use in conjunction with equipment such as found in telephone distribution centers or the like, wherein a large number of soundor electrical impulse transmission lines and cables are brought to a given location for interconnection with other transmission lines. l-leretofore various apparatus for effecting the necessary interconnection of lines and cables have been provided; however, because of certain design characteristics, such apparatus have been beset with one or more of the following shortcomings: (a) the apparatus was of bulky construction, thereby requiring an inordinate amount of floor space to accommodate same; (b) the wire termination block density for a given frame was minimal because the blocks were fixedly secured to the frame, thereby necessitating greater clearance between adjacent blocks to provide the necessary access to the terminal posts carried on the blocks; (c) because of the fixed positions of the blocks, the wire connecting and disconnecting operation wasa tedious manipulation requiring the talents of one possessed of a high degree of dexterity; and (d) the installation of the prior apparatus required an excessive amount of on site labor.
SUMMARY OF THE INVENTION Thus, it is an object of this invention to provide an assembly which avoids the aforenoted shortcomings associated with prior apparatus of this general type.
It is a further object of this invention to provide a frame and wire termination block assembly wherein the blocks thereof are mounted on the frame so as to form a multi-level module where each block thereof may be tilted independently of the others and, thereby, greatly facilitate the wire connecting and disconnecting manipulation.
It is a still further object of this invention to provide a frame and wire termination block assembly wherein the various components thereof may be substantially preassembled in modular forms thereby minimizing the amount of on site labor required during installation of the equipment.
Further and additional objects will appear from the descrip tion, accompanying drawings, and appended claims.
In accordance with one embodiment of this invention, an assembly of the type described is provided which includes a support and an elongated member mounted on the support and angularly disposed with respect thereto. Mounted on and projecting from the elongated member is a pair of spaced brackets. Disposed between the brackets and adjustably mounted thereon is an elongated wire termination block which is adapted to assume selected-positions of tilted adjustment. Guide means for wire and cable are mounted on the elongated member and are disposed adjacent the block.
DESCRIPTION For a more complete understanding of the invention, reference should be made to the drawings, wherein:
FIG. I is a fragmentary perspective front view of one form of the improved assembly.
FIG. 2 is similar to FIG. 1, but showing only a portion of the assembly with various blocks thereof in selected positions of tilted adjustment.
FIG. 3 is a fragmentary sectional view taken along line 3-3 of FIG. 1.
FIG. 4 is an enlarged fragmentary end view of the assembly of FIG. 2 and with one of the blocks thereof in a tilted position and showing the accessibility of the terminal posts of the tilted block with respect to a soldering tool or the like.
FIG. 5 is an enlarged perspective view of the connection between one end of a block and a bracket element; the component parts of the connection are shown in exploded relatron.
Referring now to the drawings, and more particularly to FIGS. 1 and 2, one form of the improved assembly is shown which is adapted to be used in conjunction with sophisticated communication and/or data processing equipment wherein large numbers of wires and cables are interconnected. One important requisite of such an assembly is that it be readily accessible so that the wire connecting and disconnecting manipulations can be readily performed. The illustrated assembly 10 comprises a pair of uprightchannel-shaped supports 11 which may extend from floor to ceiling. If desired, however, the supports 11 may be arranged so as to form a section, self-supporting frame having a base module X, resting upon a floor surface, a block module Y interfitting with and extending upright from the base module X, and a top module 2 interfitting with and overlying the block module Y. Each of the aforesaid modules may be preassembled, thus, requiring only interfitting of the modules on site."
The supports are retained in spaced substantially parallel relation by a plurality of transversely extending cross members 12 which are affixed to the supports and are arranged in spaced substantially'parallel relation. The number of members 12 utilized will depend upon the number of wire termination blocks 13 required for the particular installation.
Each block 13 is preferably of like construction and is provided with an elongated rectangularly shaped center portion 14, an elongated wing-shaped side edge piece 15 secured to the outer elongated edge of the center portion, and an elongated shield piece 16, see FIG. 5. All of the aforenoted components 14, 15 and 16 of the blocks 13 are preferably extrusions. Furthermore, the shapes of pieces 15 and 16 may be varied fromthat shown and will depend upon the particular installation. The block components are described in detail in my copending application filed concurrently herewith and entitled Wire Termination Block Construction."
The center portion 14 of each block 13 is provided with a plurality of terminal posts or pins (e.g., 1,000) 17 which project from opposite sides of the center portion, see FIGS. 4 and 5. The posts may be arranged in 10 rows of posts each. It is preferred that the post on each side of the center portion be inclined approximately 45 toward the outer piece 15. The desirability of the post incline will be discussed more fully hereafter. 1
Mounted on and projecting outwardly from each member 12 is a pair of bracket units 18, see FIGS. 4 and 5. A wire termination block 13 is positioned between each pairof units and is adjustably supported thereby so that the block may be manually moved to various positions of tilted adjustment, see FIG. 4. In addition to the tilted positions, the block may be moved to a horizontal position, which is the position it would normally assume once the necessary connections to the posts 17 have been made.
Each bracket unit 18 in the illustrated embodiment includes an elongated horizontally extending arm 20, one end 200 of which is adapted to be fixedly secured to the adjacent member 12. The outer or opposite end 20b of the arm is provided with a pair of horizontally spaced openings 21 and 22. Opening 21 is adapted to receive a pivot pin 23, the leading end 23a of which is adapted to be threaded into an opening 24 formed in the endface of block piece 16. Disposed between the endface of block piece 16 and arm 20 is a washer 25 and a lock piece 26. Piece 26 is provided with a semi-circular front portion 26a and a rearwardly projecting tab 26b, the latter being provided with an opening 26c through which pin 23 is adapted to extend. The rear edge of front portion 26a is offset so as to form a pair of flanges 26d. The flanges are adapted to engage the laterally extending portions 16a and b of block pieces 16 so that the lock piece 26 and shield piece 16 will pivot as a unit about pin 23 as an axis.
Front portion 26a is provided with a plurality of arcuately spaced radiating slots or pockets I, II and Ill. Each slot is of like configuration and isadapted to accommodate a springloaded detent 27, which in turn, is disposed within the opening 22 formed in the outer distal end 20b of arm 20. The detent 27 may be of conventional construction and includes a sleeve 270 which is fixedly secured to the arm, a coil spring 27b disposed within the inner open end of the sleeve, a plunger 27c provided with an annular shoulder27d slidably disposed within the open inner end of the sleeve, and an exposed button 27e having a shank portion 27f which slidably extends through an opening formed in theouter end of the sleeve. The inner end of the button shank is secured by any suitable means to the outer end of the plunger 27c. The opposite or inner end 273 of the plunger is shaped so that it will properly fit within the selected one of the slots I, II, or Ill and thereby retain the block 13 in either of two tilted positions or in the horizontal position, see FIG. 4. The outer end of the button 27e has an enlarged head 27h which is impassable with respect to the opening formed in the outer end of the sleeve 27a. To release the plunger end 273 from an interlocking position with respect to one of the slots I-lll, merely requires a manual outward pull on thebutton head 27h until the plunger end is free of the slot,
whereupon'the block can be pivoted about pin 23 as an axis.
The number of slots and the angular relationship of the slots may be varied from that shown. In the illustrated preferred embodiment, slots I and II are approximately 90 apart with slot ll bisecting such included angle. When the block 13 is in tilted position A, see FIG. 4, the terminal posts 17 projecting from the upper surface of the center portion 14 of the block are readily accessible for the wire connecting or disconnecting manipulation wherein a soldering tool T is normally utilized. When the block is disposed in tilted position B, see FIG. 2, the underside of the block center portion 14 is readily accessible for a similar manipulation. Once the necessary connecting and disconnecting manipulations have been performed, the block is returned to its normal horizontal position C. As aforementioned, the spring-loaded detent 27 cooperates with a lock piece 26 to retain the block in the selected position of adjustment.
As seen in FIG. the shield piece 16 of the block is provided witha plurality of large openings 16c through which the various wires are caused to pass. By utilizing the openings 16c the various wires may be readily segregatedfthusfacilitating tracing of the wires, when required.
As seen in FIGS. 1 and 3, the blocks 13 are in vertical alignment and each is spaced a substantial distance outwardly from the horizontal member 12. Disposed within such spacings are a series of wire guides 28, there being a series of guides for each block. Each guide 28 of a series is preferably formed of rod stock which has been bent into either a J or C shape. The horizontal leg 28b has the inner end thereof affixed to the horizontal member 12, except as to the end guides of the series, which may have the leg portions 285 thereof affixed to a portion of the bracket arm 20, see FIG. 5. The horizontal legs 28b of the guides of a series coact with one another to serve as a support for wires or cables laid thereupon. The offset leg 28a limits lateral movement of the supported wire or cable and, thus, prevents a interference by the wires and cables with the pivotal adjustment of the adjacent block. It is important that the wires connected to either the top or bottom terminal posts 17 of the block be provided with a sufficient stress relief loop when the block is in its normal non-tilted position, so that subsequently the block can be readily adjusted to various tilted positions without undue strain being imparted to the wires.
In addition to the guides 28, there may be provided a second series of wire guides 30 which are spaced longitudinally along member 12 and project therefrom in a direction opposite from brackets 18 and guides 28, see FIG. 3. Each guide 30 of a series has a bail portion 300 spaced outwardly from member 12.
Corresponding guides 30 of the second series are in vertical alignment and, thus, enable certain of the wires and cables to be segregated from one another while extending vertically from one block to another.
Besides the first and second series of guides, a third series of guides'3l may be provided ,in which the guides thereof are spaced endwise of the blocks and are secured to either the members 12 or one of both of the supporters l1 and serve to guide the vertically extendingwires or cables which extend from adjacent equipment.
While the illustrated assembly 10 is shown as having termination blocks disposed on only one side of the members 12, it is to be understood, of course, that the blocks may be disposed on opposite sides of the members without departing from the scope of the invention. In addition, if desired, the supports ll may run in horizontal directions and be secured, respectively, to the floor and ceiling, in which case the adjustable blocks would extend vertically rather than horizontally, as shown. In either illustration, the adjustability of the block is the same.
Because of the adjustability of the blocks, greater block density for a given frame is possible because the spacing between adjacent blocks may be reduced without interfering with the wire connecting and disconnecting manipulations.-
The various parts of the assembly are of such design that they may be substantially preassembled, thereby reducing on site" labor to a minimum during initial installation of the apparatus.
