ZNyENTOR.

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.

ig. 8 indicates a fnodioation. Nun1efa1 45 Inay be a oasing oontaining al suitable nun1bef of fefnale sooket elen1ents, 3ds deSofibed, vvhich afe Suitably vvifed, the oonduotofS leaving coSiffg in the fofn1 of the cable 46. is a plug housing of handle containing lug fnefnbefs extend ing thefeffofn, as shown, fof engagen1ent with aSSooiated feff15Lle Socket n1enlbefS in the housillg 55, the plugS being Suitably vvifed and the ooI1- ductofs leaving the caSin f if1 the fofm of the cable 48.

The laSt exonlple is only one of nlany app1ioa tiof1s of the invention that wi11 occuf to those Skilled in the aft, It shovvs that the diSclos11fe is f1ot lifflited to uSe in oonnection With plug and jack of Sooket StfuotufeS as con1Inon1y undef Stoodo fhe contact Spfing has been shown aS a U- shaped leaf Spfing anchofe With its ffee ends in the Shallow gfoove of fold foffned by the ofifflp in the feIna1e jack she11. 1/fod.incationS afe, of coufse, possible.

Pof eXan1ple, depfessions fnay be fofnled in the if1Side Wall of the Socket shelL one fof each ffee end of the legs of the spfing (Which fnay be slightly feoced to fofn1 a Shouldef, if (iesifed) of two holeS may be ofilled in the Sooket Shell fofIning the depfeSSionS in vhioh the ffee ends of the SpfingS ofe to be anchofed. Such n1odioa fionS vil1 autofflatically 1ocate the contact Spfiog if1 its desifed angulaf poSition within the socket S1 1e1l The contaot spfing fnay also be pfovided With eXtenSionS pfoeoting latefa11y ffoIn its baSe; e. g., Suitable eafS fnay be punChed out and fofffled of the Spfing matefial at the baSe thefeof. Such extenSions of eafs Inay then be anchofed in a shallovv gfoove neaf the ffee end of the socket Shell in a sifnilaf fnanf1ef in Which the ffee ends of the Spfing legS ofe anchofed in the stfuotufe illuStfated in the dfaWings of they fnay be an chofed in depfessionS Suoh aS holeS dfilled into the vva11 of the socket Shell fleaf ifS ffee end- I11 the lattef oaSe, the eafS punched oL1t ffon1 the baSe ffloy be slightly feduced to foffn latefal pfojeCtions fof engagefnent With the holeS in the sooket she11. he legS of the Spfing in in eithef caSe be ffee fof eXing fnotion againSt the she11 Wan.

The base of the contaot spfing Inay a1So be figidly attaohed to the Sooket she]1 by extenSionS of by fofIning a SUitoble cloS11fe, e. g., by tufning in the fnatefia1 of the She11 suffioiently to fofm a Suppoft at itS ffee end fof the attaChment of the base of the spfing, e. g., by spot welding, fiveting of the like.

The body of the t o legS of the spfif1g nlay be pfe-foffned in ofoss-Seotioflally oufved shope to pfeSent genefally longitudinally extending convex oootoot SuffaceS fof engagen1ent With the plug element.

The ffee end l5 of the sooket She11 need not be tufned in aS ffluch as illuStfated, of the tufning-in nlay be ofnitted leavif1g in eithef case an opening thfough Which the contaot Spfing is insefted ilfSfead of if1Sefting it ffofn the othef end aS deScfibed.

SevefaL o. g. thfee, oof1tact spfingS nlay be pfovided, each fnade if1 the fofIn of a longitudinally Cufved cfosS-Sectionally ffat of cfoSS- seotionally oufved leaf Spfing having if deSifed, oufved of founded ffee ends. A pin1ike IneInbef fnay be sffitably attached to each spfing to pfo ject ffon1 itS ooncave side pefpendioulafly thefe of fhfee fadial holes may be foffned in the socket She11 if1 angulaf poSitions of fof fetherefroIn, and fastening n1eans dis osed vvithin and eXtending aXiany thTough each tubular Shell-1ike IT1eInber oarrying Suoh Sleeve for se ouTing the device in engagen1ent With said n1ount ing, each tub11lar She11-1ike IneInber caTrying such Sleeve and containing S11oh fastening lneans forIning a Inounting IneInber aIld also forIning an index IneInber to detern1ine the plug-in po sitioI1 of the p111gs oarried on the Support of a plug terminal devioe coacting With Sid socket teTIninal device.
