DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIGS. 1, 2 and 3 there is shown a wiring adapter constructed in accordance with the concepts of the invention. Wiring adapter 20 comprises a base member 22 having a generally T-shaped cross sectional configuration substantially as shown. A first or upper surface 24 of base member 22 is provided with a series of selectively spaced, parallel first recesses 26 of surface 24. The depth and width of the first recesses 26 may be selectively choosen so as to permit a conductor or contact extension to be suitably disposed therein while the top most part of such conductor (not shown) protrudes slightly above the first surface 24. A

v second surface 32 and a third surface 34 define, respectively, the opposing sides of the enlarged portion of the T-shaped base member 22. A second series of recesses 36 extend from even ones of the first recesses 26 along the second surface 32 and a third series of recesses 38 extend from odd ones of the first recesses 26 along the third surface 34 as is more clearly seen in FIG. 2. Recesses 36 and 38 extend obliquely across surfaces 32 and 34, respectively, in generally equal but opposing angular orientation with respect to the longitudinal axis of base member 22, converging along an axis remote from the first surface 24, the axis of conversion being oriented substantially normal to the longitudinal axis of base member 22. Although the recesses 26, 36, and 38 are illustrated as being generally rectangularly contoured, the arrangement may be readily modified where necessary or desirable to provide a semicircular, elliptical, or V-shaped cross sections without departing from the spirit of the invention and within the concepts herein disclosed. Thearrangement thus described defines essentially two sets of preferably contiguous recesses, one set comprising the odd ones of the recesses 26 and the recesses 36 communicating therewith, and the other set comprising the even ones of recesses 26 and the recesses 38 communicating therewith. The T- shaped cross sectional configuration of the wiring adapter 20 shown in FIG. 1, although generally suitable for many applications, may be appropriately modified, to define a generally tapered or rectangular crosssection, as shown for example, in FIGS.9 and 11, at 40 and 42 respectively. It will of course be readily appreciated that in each of the configurations shown in FIGS. 1, 9, and 11, any one or more of the generally planar surfaces may be arcuately formed, where necessary or desirable, without departing from the spirit of the invention and within the conceptsherein disclosed. The number of recesses provided in the base member 22 should of course be choosen to provide a number sufficient to provide at least one recess therein for each of the terminal ends to be engaged therewith. With reference specifically to FIG. 3, a wiring adapter such as 20 may be coupled to a further device such as a socket means 44. As illustrated, socket means 44 may comprise a given number of parallel pairs of contacts 46 (See FIG. 8) each having an extending portion 48 protruding a given length from a rear surface 50 of socket extending between a first edge 28 and a second edge p means 44. In the arrangement shown, each laterally disposed pair of contact extending portions 48 is longitudinally spaced a given distance S, from an adjacent pair, the distance S, generally being choosen to provide mating cooperable relationship with oneform or another of receiving member (not shown) which com prise a mating plug or a plurality of conductive strips or contacts disposed on either one or both surfaces of a printed circuit board 76 such as shown, for example, in FIG. 10. The respective pairs of extending portions 48 may be separated one from anotherby divider portions 52 molded into or otherwise formed adjacent the surface 50 of socket means 44. To effect the alteration of the relative spacing and disposition of the extending portions 48, the wiring adapter20 is positioned intermediate the two rows of contact extending portions 48 and each of the portions 48 selectively guided within an associated one of the second and third series of recesses 36 and 38, respectively. Due to the oblique angular orientation of each of the recesses 36 and 38, each of the upstanding portions 48 will be required to be slightly reoriented to seat appropriately in its respective recess. As further illustratedin FIG. 3 the lower portion of the wiring adapter base member 22 may be castellated, as at 54, to provide a series of slots 56 selectively spaced and suitably proportioned to accommodate a respective one of the dividers 52. The remaining length of portions 48 extending beyond the first surface 24 of base member 22 is further displaced to lie within a re spective one of the recesses 26, as shown in greater de tail in FIGS. 4 and 8. Thus the original spacing S, be

tween adjacent pairs of contact extending portions 48 is effectively altered to provide a series of extending portions 48 disposed in an alternate array having a spacing S between adjacent ones thereof (see FIG. 4). Where the extending portions 48 and the recesses 26, 36 and 38 of base member 22 are arranged in a symmetrical pattern of equally spaced elements, the spacing S between adjacent portions 48 will be essentially equal to one half the original spacing S,. It will of course be readily apparent to those skilled in the art that various selective patterns or arrays may be obtained merely by altering the symmetry and spacing of the respective first, second, and third series of recesses 26, 36, and 38. For example, in the embodiment illus' trated in FIG. 12, a base member 78 is provided with a series of first recesses 80, a series of second recesses 82, and a series of third recesses 84. The first recesses 80 are dispositionally arranged to provide a pattern consisting of pairs of relatively closely spaced recesses spaced a distance S, from one another each pair being relatively widely spaced a distance greater than S, from an adjacentpair. The second-and thirs series of recesses, 82 and 84, respectively, convergingly extend from respective odd and even ones of recesses 80 in a manner essentially equivalent to that described above with respect to recesses 36 and 38 shown in FIG. 2, the con verging recesses 82, 84 having a pitch or spacing 8,. However, in this case, because of the unequal spacing between recesses 80, the spacing S; will be somewhat less than one-half of the spacing S Thus, it is readily apparent that almost any desired pitch alteration may be accomplished in a similar manner merely by selectively varying the spacing between adjacent pairs of first recesses 80 and the spacing between the recesses 80 forming each such pair.

- centers and the individual conductors 60 of cable 58 are disposed on 0.0425 centers. It should, of course, be readily understood that these dimensions are not critical but are illustrative merely of configurations in common use at present. In the event it is desired to connect the flat cable 58 to the socket means 44 at a given area intermediate the ends of the cable 58, a selective portion of the insulation adjacent such area is removed from either one or both surfaces of the cable, as at 62, to at least partially bare a selective length, of the conductors 60 substantially as shown (see FIG. The bared portions of conductors 60 are then placed over the first surface 24 of wiring adapter 20, as illustrated in FIG. 6, and the'assembly joined together by solder,- ing, welding, or any other commonly employed means for joining conductive elements. Thus, as may be more clearly seen in FIG. 7, the contact extending portions 48 having a pitch S have been selectively interconnected to a plurality of conductors 60-having a pitch S different than 5,. Although the wiring adapter 20 is shown as an element separate and apart from the socket means 44, it may be formed or molded integrally therewith to provide a composite assembly for convenient employment in a particular application. The device may also be provided in discrete, predetermined sections or lengths for selective pitch alterations of a selected portion of a particular array of contacts or conductors.

Although recesses 26 of wiring adapter 20 may extend completely across the firstsurface 24in direct communication with both the first and second edges 28 and 30 of base member'22 as illustrated for example, in FIG. 1, such arrangement may be modified as shown for example in FIG. 11 wherein there is illustrated a plurality of first recesses 64 extending partially across an upper first surface 66 of a base member 42, each of the recesses 64 being separated from an adjacent recess and one of the edges of member 42 by raisedportions 68. This arrangement may be found particularly advantageous where it is desired to prevent the inadvertent flow of solder or other bonding material between adjacent recesses during the bonding operation.

Referring now to FIG. there is shown a further embodiment of a wiring adapter 70 constructed in accordance with the concepts of the invention. In the example illustrated the adapter 70 may be employed to alterthe predetermined pitch of a series of contacts 72 disposed in parallel-pairs along one edge 74 of a printed circuit board 76. To effect the alteration of the existing pitch of contacts 72 it ismerely necessary'to position the-wiring adapter 70 intermediate the two rows of contacts 72 in a manner similar to that described above with respect to the arrangement illustrated in FIG. 3. The disposition of the contacts 72 within the recesses provided in the wiring adapter 70 is also accomplished in a manner similar-to that described above with respect to'the arrangement'of FlG. 3, whereby the originalpitch or spacing of the contacts'72 is thus selectively altered according to the pre-arranged'disposition of the recesses in wiring adapter to permit their cooperative interengagement with, for example, a further series of conductors having a pitch different than that of the contacts 72.

The. instant adapter, although illustrated as comprising an essentially straight elongate member, may of course, be'selectively formed in various curved or arcuate configurations, for example, for mating engagement with a complementarily formed further member with which such adapter is to be employed.
