US. Cl. 179/97; 179/91 R Primary ExaminerKathleen H. Claffy Assistant Examiner-C. T. Bartz Attorney, Agent, or FirmTemko & Temko [57] ABSTRACT A modular jack strip assembly suitable for telephonic and similar applications including means for removably maintaining label indicia of each jack opening in each of a plurality of jack strip elements. Each jack strip element is provided with grooves forming means 52 E H04M 5/02 cooperating with corresponding forming means on a [58] Field 61 Search 179/97, 91 A 91 R, 93, juxtaposed J Strip element to retain indicia- 179/95 75, 6] 65, 68, 57 bearing card or strip therebetween, the strip being insertable from either end of the juxtaposed jack strip [56] References Cited elements- UNITED STATES PATENTS 5 Claims, 3 Drawing Figures 1,930,275 l0/l933 Knowlton et al. 179/91 1 MODULAR JACK STRIP ASSEIVIBLY BACKGROUND OF THE INVENTION This invention relates generally to the field of telephone switching, and more particularly to modular jack strip assemblies of known type which comprise a plurality of juxtaposed jack strip elements mounted on a frame in parallel fashion for maximum space utilization with close spacing of individual jack openings. Owing to the relatively small size of such jack openings, individual labeling or other identification at points immediately adjacent the jack opening is often difficult, and, in some cases, impossible. It is known in the art to provide indicia at the end of a row of jack openings, which information can be interpolated for application to an individual jack opening, but such expedience are only partially satisfactory, and have not been widely used- BRIEF DESCRIPTION OF THE PRESENT INVENTION Briefly stated, the invention contemplates the provision of a plurality of jack strip elements of known type having an exposed surface surrounding the jack ,entry openings, the surface supporting a groove forming member in parallel relation thereon, the groove forming member defining a pair of oppositely facing grooves which are spaced from the transversely extending edges of the exposed surface to cooperate with similar grooves on adjacent jack strip elements to form a channel into which an indicia bearing strip may be inserted in such manner that when in fully seated position the proper indicia is adjacent the respective jack opening for immediate identification. Should the connection to the jack be changed, it is necessary only to correct the individual indicia associated with that jack opening, which correction may be facilitated by a temporary removal of the indicia bearing strip. By providing end edge grooves which are continuations of the transversely extending grooves, additional indicia relating to an entire jack strip element may also be accommodated. For identification of the jack openings in the last of a series of jack strips, an auxilliary groove forming member is provided to form a final channel independently of another jack strip element.

BRIEF DESCRIPTION OF THE DRAWING In the drawing, to which reference will be made in the specification, similar reference characters have been employed to designate corresponding parts throughout the several views.

FIG. 1 is a fragmentary end elevational view of an embodiment of the invention.

FIG. 2 is a fragmentary front elevation view thereof.

FIG. 3 is a fragmentary side elevational view thereof, partly in section.

DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENT In accordance with the invention, the device, generally indicated by reference character is an assembly comprising a supporting frame element 11, a plurality of jack strip elements 12, a plurality of indicia cards or strips 13, and a terminal strip member 14.

The supporting frame element 11 is of conventional type, including first and second angular frame elements 16 and 17, respectively, each including a forward flange l8 defining orifices 19 for the mounting of jack strip elements 12 in juxtaposed parallel relation by means of screws 20.

The jack strip elements 12 are substantially similar, each including a molded plastic housing 22 defining an exposed forward wall 23, and a plurality of longitudinally extending walls 24 supporting plug engaging structure (not shown) of well known type. The forward wall 23 includes an inner surface 27 and an outer surface 28 penetrated by plug engaging bores 29 provided with metallic sleeve linings 30. Laterally extending portions 31 and 32 provide mounting holes 33 engaged by the screw means 20 to fix a plurality of strip elements in the juxtaposed relation shown in FIGS. 1 and 2, in which position corresponding abutting surfaces 35 and 36 position the jack strip elements in spaced relation corresponding to the orifices 19 in the frame element 11.

Projecting outwardly from the outer surface 28 on each of the jack strip elements 12 is a groove forming member 38 of generally rectangular configuration, and bounded by longitudinal edges 39 and 40 as well as end edges 41 and 42. Inwardly of the outer surface 44 of the groove forming member 38 is a continuous groove 43 best seen in FIGS. 1 and 3.

The indicia cards 13 may be of paper stock or synthetic resinous material, and are bounded by first and second end edges 46 and 47, first and second longitudinal edges 48 and 49 and first and second surfaces 50 and 51. Suitable indicia 52 are disposed on at least one of the surfaces 50-51 such that when the cards 13 are positioned within a channel formed by opposed portions of grooves 43 on two adjacent strip elements 12, the indicia will be disposed opposite a respective jack opening or bore 29.

The terminal strip member 14 may be conveniently formed as a metallic stamping, and is useful for the positioning of an indicia bearing strip at either end of a line of jack strip elements where there is no groove present to support one edge of the card. It is of a length corresponding to that of the groove forming member 38, and includes a planar portion 54 which can be suitably attached to a surface 53 of a jack strip element by drive screws, the portion 54 supporting a curved flange 55 defining a groove 56, the groove 56 cooperating with a portion of a groove 43 on the mounting jack strip element to provide a channel accommodating a card 13.

From a consideration of FIG. 3, it will be observed that the groove 43 also provides portions 60 disposed at right angles to those supporting the indicia cards 13. Where a plurality of devices 10 are assembled in coplanar relation, it is possible to utilize the groove portion 60 to support larger indicia cards having a principal axis disposed at right angles to those of the cards 13 for additional identification purposes.

I wish it to be understood that I do not consider the invention limited to the precise details of structure shown and set forth in this specification, for obvious modifications will occur to those skilled in the art to which the invention pertains.

What is claimed is:

1. In a modular jack strip assembly of a type including a plurality of juxtaposed jack strip elements carried by a supporting frame element, each of said jack strip elements including a plurality of jack openings positioned in an exposed wall thereof along a single transversely extending axis, improved means for supporting an identifying indicia for each opening comprising: an elongated groove-forming member extending outwardly from said wall on each of said jack strip elements, and having a principal axis parallel to said transversely extending axis. said groove-forming member at least partially surrounding at least one of said jack openings and defining an elongated groove parallel to said principal axis along at least one edge thereof; said jack strip elements being so assembled upon said frame element that an elongaged groove on one of said jack strip elements is disposed opposite a corresponding elongated groove on another of said jack strip elements to define a channel therebetween, and an elongated indicia-bearing strip member slidably insertable into said channel between said grooves to position predetermined indicia thereon adjacent said at least partially surrounded jack opening to identify the same.

2. Structure in accordance with claim 1, in which said groove-forming member completely surrounds at least 4. Structure in accordance with claim 3, including an auxilliary terminal strip member mounted upon a surface of one of said jack strip elements and defining a groove opposing in spaced relation one of the grooves defined by the grooveforming member of said one of said jack strip elements.

5. Structure in accordance with claim 2, in which said groove-forming member is of rectangular configuration, and defines a continuous groove having four rectilinear sides.
