HiS Aomev she11 nef its ffee end fof anchofing the Wife. The tuff ngin of the ffee end of the sooket she11 Inay thuS be ofnifted. A condnctof suCh aS 39 iS aSSociated with the plug l3. The end of the conductof 39 nlay be plaoed into the hole in the plug fnefnbef 3 and may be soldefed in place. soldefing tab Inay be aSSociated With the p111g l3, if desifed.
The socket and plug elefffents of the Stfuctufe shown if1 igs- 6 and 7 `afe Shown aSSooiated with conduotofs, i11 the fI1af1nef descfibed obove. The conductofS aSSociated with the endS of the fe fnale Socket eleII1ents afe gathefed iflto the oab1e indicated at 4n and the conductofs aSSooiated vith the fnale plug ffleInbefS afe gathefed to foffn the calble 4l.
The tilted position of the' plug suppofting st1'ip lo, vvith feSpect to the jack of socket caffief stfip 2o, as shown in ig. 7, f1dicateS that the inseftion of the plug fffeITlbefS into theif aSSooiated socket elefnents doeS not depend on axi1 ahgnment thefeWith. The plug Stfip l4o is fof convenience shown in a stfai ht1ine which extends at an angle to the plane of the insulating nlefnbef l2o of the jock stfip. In actual fnanipulation in pfactioe, the plug stfip l4o Inay be fiexed afld vi11 fiex incident to inSeftion of the plugS into the socket elefnentS. The extef1t of nexing of the plug Stfip vvill, of coufSe, depend on nonlefonS factofS ff1c111diflg the felafive stiffflesS of the inSulating Ineff1bef ffo and the nufnbef of fows of plugS it oaffieS, aS vve11 as the Inannef in vVhich theSe plugs afe a1-fanged. If1 aJ fe1ative1y Shoft Stfuc tufe exing wi11 be lesS thaf1 in an felatively long stfuofufe.
Bough handling of deviceS Inade fo accofdance with the invention, if1olllding pufpoSefu1 tflting, exing and deffecting if1 any desifed angolar di fection, iffcideflt to insefting and fen1oviffg of the plug stfip With fespeot to the aok Stfip, a-nd applying oonSidefable fo1,ce, if1C111ding a%ngulaf gfifldif1g fofoe, dufing such fnan pulation, pfoved flo detfin1ent Whatsoevef to the StfuctufeS These nlanipulations inolnded fo1cefu1 fefnova1 of the jack stfip in a fipping-off action at one end. The plugs disengagedL in a pee1ingoff n1otiof1 ffom end to end of the Stfip with no detfnent to the paftS, The Contact Spfings Wefe fleithef pushed ouf of line, nof Wefe they bent loosened of daff1- ged i11 any Way if1 any one of the teSts ap )1ied fS a nlattef of faot, fofoes Wefe app1ied to the point of bending of looSef1ing one of the othef plug nlefnbef, and yet n daInage Was done to the coaoting fefnale Socket eleInent of to itS aSso ciated contact spfing, and the spfing feInajned in itS aSSigned position.
t Will be noted that the left end of the plug Stfip fof is eXtended beyond the coffeSponding end of the jock Stfip !2o to faoilitate itS fflazflipfl- 1otion.
vvfong iflSeftiof1 of the plugS on the plt1g stfip lo if1to the Sooket elen1ents on the jaok Stfip l2o is pfevented by the sofews 33 and 3 by ffleanS of Which the jack sffip iS Inounte on the SLlp poft 2. These sofews have the dua1 pufpoSe of ff1o11ffting the jaok stfip ond of acting as indeX ing of key fneanS Should the plog stfip lo be inadveftently fevefSed ffofff its inteflded poSition, plugging-in v0u1d be pfevented by p1LIgS in the plL1g stfip which would enCountef the sofeWS 33 and fespectively, iflstead of theif aSSooiated feff19ule Socket elen1ents. ffny Selected socket eleInentS ffloy thus be uSed ouS key of index meanS.
