Opfindelsen angår et elektrisk kontaktorgan til elektrisk forbindelse til en isolationsbeklædt elektrisk leder, navnlig til anvendelse i elektrisk forbindelsesled for flere kredsløb af den art, som anvendes i mange typer og antal i kommunikationssystemer og databehandlingssystemer. Kontaktorganet er af den art, som har en af tynd, elastisk, elektrisk ledende metalplade fremstillet del, der har en slids med en øverste del med nedad konvergerende overflader til deling af lederens isolation, og en nederste terminalsektion til tilvejebringelse af kontaktindgreb med lederen.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an electrical connector for electrical connection to an insulation lined electrical conductor, in particular for use in multiple-circuit electrical connectors of the kind used in many types and numbers in communication systems and data processing systems. The contact member is of the type having a thin, elastically electrically conductive metal plate having a slit having a top portion with downwardly converging surfaces for dividing the conductor insulation, and a lower terminal section for providing contact engagement with the conductor.
Ved de kendte konstruktioner af denne art medfører dette den ulempe, at der ved ledningens indføring i slidsen kun tilvejebringes et relativt lille kontaktareal, samtidig med at slidsens kanter kan skære sig ind i selve lederen og beskadige denne.In the known constructions of this kind, this causes the disadvantage that, when the lead is introduced into the slot, only a relatively small contact area is provided, while the edges of the slot can cut into the conductor itself and damage it.
Fra beskrivelsen til svensk patent nr. 149.lo5 og tysk patent 2 141423 nr. 1.263.13ο kendes således kontaktorganer, hvor den øverste del af slidsen har i forhold til pladetykkelsen fortyndede kanter til indtrængning i lederisolationen, medens den nederste del har samme tykkelse som materialet, hvoraf kontaktorganet er fremstillet. Når der anvendes et tyndt plademateriale, er der derfor kun et lille kontaktareal mellem kontaktorganet og lederen. I det ovennævnte tyske patentskrift er der opnået et større kontaktareal ved at anvende et tykt plademateriale. For i dette tilfælde at få en passende fjedring er materialet under den lederoptagende slids forsynet med en særskilt fjederslids.Thus, from the specification of Swedish Patent No. 149.lo5 and German Patent 2 141423 No. 1.263.13ο, contact means are known in which the upper part of the slit has diluted edges for penetration into the conductor insulation, while the lower part has the same thickness as the material from which the contact member is made. Therefore, when a thin sheet material is used, there is only a small contact area between the contact member and the conductor. In the above-mentioned German patent, a larger contact area is obtained by using a thick sheet material. In this case, to obtain a suitable spring, the material under the conductor receiving slot is provided with a separate spring slot.
Opfindelsen går ud på at udføre et kontaktorgan af den angivne art af tynd metalplade således, at der opnås et større kontaktareal og en bedre fastholdelse af lederen med friktionsindgreb uden fare for beskadigelse af lederen.The invention is to provide a thin metal plate contact means such that a larger contact area is obtained and a better holding of the conductor with frictional engagement without danger of damage to the conductor.
Med henblik herpå består det for opfindelsen ejendommelige i, at terminalsektionen har glatte, i forhold til pladetykkelsen fortykkede kanter til dannelse af trykkæber i friktionsindgreb med den indførte leder.For this purpose, it is peculiar to the invention that the terminal section has smooth, thickened edges relative to the plate thickness to form friction jaws in frictional engagement with the inserted conductor.
Ved den angivne fortykkelse af kanterne i den nederste del af slidsen opnås således den ovenfor angivne tilstræbte virkning, idet der under anvendelse af tynd fjedrende metalplade opnås en stor fjederevne, der frembringer en kraftig fastklemning om lederen med en stor pålidelighed af kontaktindgrebet, samtidig med at det opnåede kontaktareal svarer til det, der kunne opnås ved et meget tykkere plademateriale.Thus, at the indicated thickening of the edges of the lower part of the slot, the above-mentioned desired effect is obtained, using a thin resilient metal plate, a large spring capacity is obtained which produces a strong clamping of the conductor with a high reliability of the contact engagement, the contact area obtained is similar to that which could be obtained from a much thicker sheet material.
Med fordel kan ifølge opfindelsen den øverste del have tynde kanter, som går over i den nederste del gennem en overgangssektion til forskydning af lederens isolation. Herved opnås der en gradvis forøgelse af det blottede areal af lederen til indgreb for de fortykkede kanter i terminalsektionen.Advantageously, according to the invention, the upper portion may have thin edges which extend into the lower portion through a transition section for displacing the conductor insulation. This results in a gradual increase of the exposed area of the conductor to engage the thickened edges of the terminal section.
For at opnå en hensigtsmæssig udnyttelse af det tynde materiales fjederkraft kan ifølge opfindelsen terminalsektionen hensigtsmæssigt have nedad divergerende vægge, som kan spredes elastisk ved indsætningen af en elektrisk leder og udøver en tilbageholdende kraft til fastholdelse af lederen i slidsen.According to the invention, in order to obtain a suitable utilization of the spring force of the thin material, the terminal section may suitably have downwardly diverging walls which can be elastically spread by the insertion of an electrical conductor and exert a restraining force for holding the conductor in the slot.
Endvidere kan terminalsektionens sidevægge ifølge opfindelsen hensigtsmæssigt ende i en glat buet bundvæg, hvilket bidrager til en sikker fastholdelse af lederen i korrekt stilling.Furthermore, the side walls of the terminal section according to the invention can conveniently end in a smooth curved bottom wall, which contributes to a secure holding of the conductor in the correct position.
Ved en særlig hensigtsmæssig udførelsesform for kontaktorganet ifølge opfindelsen er fortykkelsen ved overgangs- og terminalsektionen dannet af lapper, der er foldet bort fra midten af slidsen og præget eller smedet, hvorved der opnås en særlig simpel fremstilling af kontaktorganet.In a particularly convenient embodiment of the contact member according to the invention, the thickening at the transition and terminal section is formed by patches which are folded away from the center of the slot and embossed or forged, thereby obtaining a particularly simple manufacture of the contact member.

Fig. 1,2 og 3 viser et terminalelement 47 dannet ved den ydre ende af et kontaktorgan 43. Det skal bemærkes, at udtrykket "ydre ende", som anvendes i den foreliggende beskrivelse, vedrører den del, som de enkelte ydre elektriske ledere er forbundet med.FIG. 1,2 and 3 show a terminal element 47 formed at the outer end of a contact member 43. It should be noted that the term "outer end" used in the present specification relates to the part to which the individual outer electrical conductors are connected. .
Den ydre ende af kontaktorganet 43 omfattende terminalelementet 47, som vist i fig. 1-3, omfatter en langstrakt kanal med U-formet tværsnitsform, og som har en bundvæg 51 og sidevægge 52 og 53. En låseflig 49 er dannet ud i et med sidevæggen 53. Fligen 49 er vist i sin begyndelsesstilling, idet den er ombøjet ca, 9o° i forhold til det øverste af sidevæggen 53, og dette er begyndelsesstillingen af fligen, når kontaktorganet 43 indsættes i en isolerende fatning. Når kontakten først er på plads i den isolerende fatning, bøjes fligen 49 udad til en låsestilling.The outer end of the contact member 43 comprising the terminal element 47, as shown in FIG. 1-3, comprises an elongated channel of U-shaped cross-sectional shape, having a bottom wall 51 and side walls 52 and 53. A locking tab 49 is formed in one with the side wall 53. The tab 49 is shown in its initial position, being bent about 9 ° to the top of the sidewall 53, and this is the initial position of the tab when the contact means 43 is inserted into an insulating socket. Once the switch is in place in the insulating socket, tab 49 bends outward to a locking position.
Terminalelementet 47 af kontaktorganet 43 har to terminalflanger 54 og 55. Flangen 54 er dannet af to flangeelementer 54A og 54B udskåret af sidevæggene henholdsvis 52 og 53. De to flangeelementer 54A og 54B er bøjet indad over enden af kanalen, som udgør terminalelementet 47, og danner en opadåben indskæring 56 (fig. 2 og 3).The terminal member 47 of the contact member 43 has two terminal flanges 54 and 55. The flange 54 is formed by two flange members 54A and 54B cut by the side walls 52 and 53, respectively. The two flange members 54A and 54B are bent inwardly over the end of the channel constituting the terminal member 47, and forming an upwardly opening notch 56 (Figures 2 and 3).
Den øverste del af indskæringen 56 har nedadkonvergerende tyndkantede 4 141423 vægge 57A og 57B (fig- 3), som danner en skæresektion til gennemskæring af isolationen på en isoleret elektrisk leder. Midterdelen af indskæringen 56 har gradvist fortykkede kanter og udgør en overgangssektion 58 til at sprede isolationen bort fra en leder indsat i indskæringen. Den nedre del af indskæringen 56 har glatte afrundede kanter langs sine vægge, som danner en terminalsektion 59, der udgør en trykkæbe, som indgriber med en elektrisk leder med glidende kontakt.The upper portion of the notch 56 has downwardly converging thin-edged walls 57A and 57B (Fig. 3) which form a cutting section for cutting the insulation on an insulated electrical conductor. The middle portion of the notch 56 has gradually thickened edges and forms a transition section 58 to disperse the insulation away from a conductor inserted into the notch. The lower portion of the notch 56 has smooth rounded edges along its walls forming a terminal section 59 which forms a pressure jaw which engages an electrical conductor with sliding contact.
Den anden terminalflange 55 på terminalelementet 47 (fig. 1 og 2) er af lignende udførelse som flangen 54. Den har et første flangeelement 55A udskåret af kanalvæggen 52 (fig. 2) og bøjet indad over kanalen. Et andet flangeelement 55b er udskåret af væggen 53 og bøjet indad over kanalen ud for flangeelementet 55A. Begge flangeelementerne er udformet med skrå øvre vægge og er bøjet tilbage på sig selv for at danne en skæresektion, en overgangssektion og en terminalsektion, som beskrevet for flangen 54 (fig. 2 og 3).The second terminal flange 55 of the terminal element 47 (Figs. 1 and 2) is of similar design to the flange 54. It has a first flange element 55A cut out of the channel wall 52 (Fig. 2) and bends inwardly over the channel. Another flange element 55b is cut by the wall 53 and bent inward across the channel next to the flange element 55A. Both flange elements are formed with oblique upper walls and are bent back on themselves to form a cutting section, a transition section and a terminal section, as described for the flange 54 (Figures 2 and 3).
For at danne en elektrisk forbindelse med terminalelementet 47 indsættes en leder 61 med en elektrisk isolerende beklædning 62 i de to indskæringer i terminalflangerne 54 og 55, som vist i fig. 2.To form an electrical connection to the terminal element 47, a conductor 61 with an electrically insulating liner 62 is inserted into the two notches in the terminal flanges 54 and 55, as shown in FIG. 2nd
Når den isolerede leder presses nedad i indskæringerne i de to terminalflanger, skærer de konvergerende indskæringsvægge, såsom væggene 57A og 57B (fig. 3), ind i isolationen på lederen med en klippevirkning svarende til den, der udføres af sædvanlige isolationsgennem-trængende terminalelementer. Når lederen presses yderligere nedad i indskæringen 56 i flangen 54, træder den ind i overgangssektionen 58.As the insulated conductor is pressed downwardly into the notches in the two terminal flanges, the converging notch walls, such as walls 57A and 57B (Fig. 3), cut into the insulation on the conductor with a cutting action similar to that of conventional insulation penetrating terminal elements. As the conductor is pressed further downward in the notch 56 in the flange 54, it enters the transition section 58.
De gradvist fortykkede vægge i indskæringen begyndende ved overgangs-sektionen 58 søger at sprede isolationen. De nedre foldede dele af indskæringens vægge i den nedre terminalsektion 59 indgriber med lederen 61 uden at skære ind i den og udøver en fuld normal kraft med glidende friktionskontakt med lederen. I fig. 3 er den endelige stilling af en elektrisk leder 61 med en isolerende beklædning 62 vist i indskæringen 56 i terminalflangen 54, hvor den elektriske forbindelse er udført. Den samme virkning forekommer ved flangen 55.The progressively thickened walls of the recess beginning at the transition section 58 seek to disperse the insulation. The lower folded portions of the notch walls of the lower terminal section 59 engage with the conductor 61 without cutting into it and exert a full normal force of sliding frictional contact with the conductor. In FIG. 3, the final position of an electrical conductor 61 with an insulating sheath 62 is shown in the notch 56 in the terminal flange 54, where the electrical connection is made. The same effect occurs at the flange 55.
Fig. 4-6 og 8 viser en anden udførelsesform for den foreliggende opfindelse omfattende et terminalelement 147 udformet som en integrerende del af et enhedskontaktorgan 143 af metalplade. Kun terminalelementet er vist. Terminalelementet 147 har en langstrakt kanalformet opbygning med en bundvæg 151 og sidevægge 152 og 153. Ved den ydre ende af terminalelementet er en del af sidevæggen 152 bøjet tværs over kanalen til dannelse af en første terminalflange 154. En anden terminalflange 155 er udskåret af den anden sidevæg 153 og bøjet indad for at ligge tværs over kanalen på et sted i afstand fra den 5 141423 ydre terminalflange 154.FIG. 4-6 and 8 show another embodiment of the present invention comprising a terminal element 147 formed as an integral part of a metal plate unit contact member 143. Only the terminal element is shown. The terminal element 147 has an elongated channel-shaped structure with a bottom wall 151 and side walls 152 and 153. At the outer end of the terminal element, a portion of the side wall 152 is bent across the channel to form a first terminal flange 154. A second terminal flange 155 is cut by the second sidewall 153 and bent inwardly to lie across the channel at a location away from outer terminal flange 154.
Terminalflangen 154 er forsynet med en opadåben indskæring 156 til modtagelse af en med isolation dækket elektrisk leder, såsom lederen 161 med dens isolation 162 (fig. 6). Den øvre del af indskæringen 156 har tynde nedadkonvergerende vægge 157A og 157B. Tykkelsen af væggene 157A og 157B i den øvre del af indskæringen 156 er begrænset til tykkelsen af metalpladen, hvoraf terminalelementet 147 er dannet, sædvanligvis af størrelsesordenen o,13 mm. Den øvre del af indskæringen 156 danner således en skæresektion til gennemskæring af isolationen 162 på lederen 161.The terminal flange 154 is provided with an upwardly opening notch 156 for receiving an insulation covered electrical conductor such as the conductor 161 with its insulation 162 (Fig. 6). The upper portion of the notch 156 has thin downward converging walls 157A and 157B. The thickness of the walls 157A and 157B in the upper portion of the notch 156 is limited to the thickness of the metal plate from which the terminal element 147 is formed, usually of the order of 0.13 mm. Thus, the upper portion of the notch 156 forms a cutting section for cutting the insulation 162 on the conductor 161.
Midterdelen af indskæringen 156 er bøjet bort fra indskæringen og er præget til dannelse af gradvist fortykkede kanter, som udgør en overgangssektion 158. Overgangssektionen 158 spreder isolationen på lederen 161, når denne fremadskridende indsættes i indskæringen 156.The middle portion of the notch 156 is bent away from the notch and is formed to form gradually thickened edges which constitute a transition section 158. The transition section 158 spreads the insulation on the conductor 161 as this advancement is inserted into the notch 156.
Den nedre del af indskæringen 156 har glatte tykke kanter, som danner en terminalsektion 159, der udgør en trykkæbe, som indgriber med den elektriske leder 161 ved en jævn glidende friktionskontakt, som giver god elektrisk forbindelse mellem lederen 161 og terminalflangen 154.The lower portion of the cut-in 156 has smooth thick edges which form a terminal section 159 which forms a pressure jaw which engages the electrical conductor 161 at a smooth sliding friction contact which provides good electrical connection between the conductor 161 and the terminal flange 154.
Terminalflangen 155 svarer i det væsentlige til flangen 154, som det bedst ses i fig. 5 og 8. Den anden terminalflange 155 er således udført med en indskæring til modtagelse af en isolationsbeklædt elektrisk leder, og den øverste del af indskæringen har tynde nedadkonvergerende kanter, som danner en skæresektion, og som går over i en midterdel af indskæringen, som har gradvist fortykkede kanter. Den nederste del af indskæringen i terminalen 155 har som i flangen 154 glatte afrundede fortykkede kanter, som danner en terminalsektion, der udgør en trykkæbe til indgribning med den elektriske leder i god elektrisk kontakt.The terminal flange 155 corresponds substantially to the flange 154, as best seen in FIG. 5 and 8. Thus, the second terminal flange 155 is provided with a notch for receiving an insulation-coated electrical conductor, and the upper portion of the notch has thin downwardly converging edges which form a cutting section and which extends into a middle portion of the notch which has gradually thickened edges. The lower part of the notch in the terminal 155 has, as in the flange 154, smooth rounded thickened edges which form a terminal section which forms a pressure jaw for engagement with the electrical conductor in good electrical contact.
I konstruktionen vist i fig. 4-6 og 8 er endedelen af kanalvæggen 153 i nærheden af terminalflangen 154 bøjet indad og udformet til dannelse af en slids 164. På lignende måde er en del af kanalvæggen 152 på linie med terminalflangen 155 deformeret indad og presset ind i en form, som danner en lodret liggende låseslids 165. I terminalelementet 147 indgriber den frie ende af flangen 154 i slidsen 164 for at fastgøre flangen og forhindre, at denne bøjes ud af stilling ved etablering af en elektrisk forbindelse med en leder, der er indsat i flangen. Holdeslidsen 165 i kanalvæggen 152 tjener det samme formål, nemlig at afstive flangen 155 mekanisk og forhindre deformation af flangen, når en elektrisk leder indsættes i terminalen 147.In the construction shown in FIG. 4-6 and 8, the end portion of the channel wall 153 in the vicinity of the terminal flange 154 is bent inwardly and formed to form a slot 164. Similarly, a portion of the channel wall 152 is in line with the terminal flange 155 deformed inwardly and pressed into a mold which forming a vertical locking slot 165. In the terminal element 147, the free end of the flange 154 engages in the slot 164 to secure the flange and prevent it from bending out of position by establishing an electrical connection with a conductor inserted into the flange. The holding slot 165 in the duct wall 152 serves the same purpose, namely to mechanically stiffen the flange 155 and prevent deformation of the flange when an electrical conductor is inserted into the terminal 147.
Terminalelementet 147 har også en låseflig 166, der er udformet ud i et med og som strækker sig opad fra den ene sidevæg 152 af 6 UU23 kanalen. Låsefligen 166 forbliver i den viste stilling, indtil en leder er blevet indsat i terminalelementet 147, og elektrisk forbindelse er blevet etableret. Når først dette er sket, kan fligen 166 bøjes om for at indgribe med den ydre overflade af den elektriske leder og holde den isolerede leder i terminalelementet 147.The terminal element 147 also has a locking tab 166 which is formed integrally with and extending upwardly from one side wall 152 of the 6 UU23 channel. Lock tab 166 remains in the shown position until a conductor has been inserted into terminal element 147 and electrical connection has been established. Once this has happened, tab 166 may be bent to engage the outer surface of the electrical conductor and hold the insulated conductor in terminal element 147.
I endebilledet i fig. 6 er sidevæggene af indskæringen 156, navnlig i terminalsektionen 159 af indskæringen, vist at divergere lidt, idet bunden af indskæringen ender i en afrundet nedre væg 167. Væggene af den lederoptagende indskæring 156 udøver således en begrænset klemkraft på lederen 161, som holder lederen i indskæringen og i elektrisk kontakt med terminalflangen 154. Med denne konstruktion bliver indskæringen 156 åbnet lidt, når lederen 161 passerer gennem overgangssektionen 158 og ind i terminalsektionen 159 af indskæringen.In the end view of FIG. 6, the side walls of the notch 156, in particular in the terminal section 159 of the notch, are shown to diverge slightly, the bottom of the notch ending in a rounded lower wall 167. Thus, the walls of the conductor receiving notch 156 exert a limited clamping force on the conductor 161 which holds the conductor in the cut-in and in electrical contact with the terminal flange 154. With this construction, the cut-in 156 is slightly opened as the conductor 161 passes through the transition section 158 and into the terminal section 159 of the cut-in.
For at forhindre for stor forvridning og sikre effektiv funktion af terminalelementet 147 er den samlede bredde af terminalelementet 147 gjort kun lidt mindre end afstanden mellem to vægge 168 og 169, som afgrænser denne del af en kontaktpassage 42 i en støbt isolerende monteringsblok 41 (fig. 6). Der er således en snæver pasning (et typisk spillerum på o,o25 mm) mellem væggene 168 og 169 af passagen 42 og terminalelementets vægge 152 og 153. Dette forhindrer for stor udvidelse af terminalelementet 147, når en isoleret leder indsættes i terminalflangeudskæringerne.In order to prevent excessive distortion and to ensure effective operation of terminal element 147, the overall width of terminal element 147 is made only slightly less than the distance between two walls 168 and 169 which delimit this portion of a contact passage 42 in a molded insulating mounting block 41 (FIG. 6). Thus, there is a narrow fit (a typical clearance of 0.25 mm) between walls 168 and 169 of passage 42 and terminal walls 152 and 153. This prevents excessive expansion of terminal element 147 when an insulated conductor is inserted into the terminal flange cutouts.
Det er ikke nødvendigt, at væggene af terminalflangens udskæringer gøres divergente i terminalsektionen på den i fig. 6 viste måde. Indskæringens vægge kan holdes parallelle over hele overgangssektionen og terminalsektionen. Dette gælder navnlig, når der findes andre midler, såsom låsefligen 166, til at holde den elektriske leder i terminalflangerne. Væggene af terminalsektionen kan således gøres parallelle med hinanden, som vist i terminalsektionen 159A, vist i fig. 7.It is not necessary that the walls of the terminal flange cuts be made divergent in the terminal section of the one shown in FIG. 6. The walls of the notch can be kept parallel over the entire transition section and terminal section. This is especially true when there are other means, such as lock tab 166, for holding the electrical conductor in the terminal flanges. Thus, the walls of the terminal section can be made parallel to each other, as shown in the terminal section 159A, shown in FIG. 7th
