Description

Sammelerde und Schutzstecker für eine Schalt- oder Trennleiste in der Telekommunikations- und DatentechnikCommon earth and protective plug for a safety or isolating strip in telecommunications and data technology
Die Erfindung betrifft eine Sammelerde und einen Schutzstecker für eine Schalt- oder Trennleiste in der Telekommunikations- und Datentechnik.The invention relates to a common earth and a protective plug for a switching or isolating strip in telecommunications and data technology.
Aus der DE 38 13 889 C1 ist eine Schalt- oder Trennleiste für die Fernmeldetechnik mit mindestens einem einsteckbaren Schutzstecker mit Gehäuse bekannt, in dem mindestens ein Überspannungsabieiter angeordnet ist, wobei jeder Überspannungsabieiter nach dem Einstecken mit dem einen Anschluß mit je einem im Gehäuse angeordneten, eine Steckzunge aufweisenden, streifenförmigen Leitungskontaktstück und mit dem anderen Anschluß mit einem an einem Montagebügel befestigten Sammelerder in elektrisch leitender Verbindung steht, wobei der Sammelerder parallel zu einer Längsseite der Schalt- oder Trennleiste angeordnet ist. Der Sammelerder weist je Schutzstecker eine Einsteckzunge auf. Das Gehäuse des Schutzsteckers weist parallel zur Einsteckrichtung in die Schalt- oder Trennleiste einen Einsteckkanal auf, in den die zugehörige Einsteckzunge des Sammelerders so einführbar ist, daß sie mit allen in ihnen angeordneten Uberspannungsableitern in elektrisch leitender Verbindung steht. Die im Gehäuse angeordneten Teile der Leiterkontaktstücke sind lose in Führungsnuten eingelegt und dienen zur Kontaktierung von Uberspannungsableitern. Die beiden im Gehäuse angeordneten Teile der Seitenkontaktstücke sind unterschiedlich ausgebildet. Das eine Leiterkontaktstück ist U-förmig und das andere S-förmig ausgebildet, wobei beide abgewinkelten Enden der Leiterkontaktstücke in einerFrom DE 38 13 889 C1 a switching or isolating strip for telecommunications with at least one pluggable protective plug with housing is known, in which at least one surge arrester is arranged, each surge arrester after plugging in with one connection, each with one arranged in the housing, a plug-in tongue, strip-shaped line contact piece and with the other connection with an attached to a mounting bracket collector is in electrically conductive connection, the collector being arranged parallel to a long side of the switching or isolating strip. The collector earth has a tongue for each protective plug. The housing of the protective plug has a plug-in channel parallel to the plug-in direction in the switching or isolating strip, into which the associated plug-in tongue of the collector earth can be inserted so that it is in an electrically conductive connection with all surge arresters arranged in it. The parts of the conductor contact pieces arranged in the housing are loosely inserted in guide grooves and are used to make contact with surge arresters. The two parts of the side contact pieces arranged in the housing are designed differently. One conductor contact piece is U-shaped and the other S-shaped, both angled ends of the conductor contact pieces in one
Führungsnut aufgenommen sind, die parallel zwischen den Führungsnuten verläuft. Die beiden Enden der Leiterkontaktstücke sind darüber hinaus zur Bildung von Kurzschlußbügeln rechtwinklig in Richtung der offenen Frontseite abgebogen. Die Enden der Kurzschlußbügel greifen in der Ruhestellung in den Einsteckkanal ein. Die im Gehäuse angeordneten Teile derGuide groove are added, which runs parallel between the guide grooves. The two ends of the conductor contact pieces are also bent at right angles to form short-circuiting brackets in the direction of the open front side. The ends of the shorting bar engage in the insertion channel in the rest position. The parts of the
Seitenkontaktstücke sind federnd vorgespannt, so daß diese erst nach dem Einsetzen der Uberspannungsableitern in die Führungsnuten eingedrückt werden. Die Uberspannungsableiter sind von der offenen Frontseite in den Schutzstecker eingesetzt und liegen federnd mit dem einen Anschluß in einer zwischen den Leiterkontaktstücken und den Uberspannungsableitern eingesetzten Schmelzpille an. Auf der Seite des anderen Anschlusses wird der Überspannungsleiter als Gegenanlage von den an den Gehäuselängsseiten angeordneten federnden Rasthaken gehalten und somit im Gehäuse des Schutzsteckers fixiert. Die Einsteckzungen der Sammelerde drücken dann die die Uberspannungsableiter haltenden Rasthaken beiseite und kontaktieren den einen Anschluß des Überspannungsabieiters, der somit mit Erde verbunden ist. Nachteilig an den bekannten Schutzsteckem ist deren komplexer Aufbau, der eine automatische Fertigung erschwert.Side contact pieces are resiliently biased so that they are pressed into the guide grooves only after the surge arresters have been inserted become. The surge arresters are inserted from the open front into the protective plug and are resiliently connected to one connection in a melting pill inserted between the conductor contact pieces and the surge arresters. On the side of the other connection, the overvoltage conductor is held as a counterpart by the resilient latching hooks arranged on the longitudinal sides of the housing and thus fixed in the housing of the protective plug. The insertion tongues of the common earth then push the locking hooks holding the surge arrester aside and contact the one connection of the surge arrester, which is thus connected to earth. A disadvantage of the known protective plugs is their complex structure, which makes automatic production more difficult.
Der Erfindung liegt daher das technische Problem zugrunde, einen Schutzstecker und eine Sammelerde für eine Schalt- oder Trennleiste zu schaffen, die einfacher aufgebaut sind und auch noch bei größeren Toleranzen eine sichere elektrische Verbindung zwischen Sammelerde und Schutzstecker gewährleisten.The invention is therefore based on the technical problem of creating a protective plug and a common earth for a switching or isolating strip, which are of simpler construction and ensure a secure electrical connection between the common earth and the protective plug even with larger tolerances.
Die Lösung des technischen Problems ergibt sich durch die Gegenstände mit den Merkmalen der Patentansprüche 1 und 8. Weitere vorteilhafteThe solution to the technical problem results from the subject matter with the features of claims 1 and 8. Further advantageous
Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Embodiments of the invention result from the subclaims.
Hierzu sind die Einsteckzungen der Sammelerde federnd ausgebildet, wohingegen der korrespondierende Erdkontakt in dem Schutzstecker mechanisch starr im Steckergehäuse angeordnet ist. Dabei ist die Geometrie der federnden Einsteckzungen auf die Geometrie der Erdkontakte abgestimmt. Aufgrund der starren Ausbildung des Erdkontaktes im Schutzstecker ergibt sich eine einfache Montage- und Automatisierungsfähigkeit bei der Herstellung des Schutzsteckers bei einer gleichzeitig hohen Leistungsfähigkeit der Erdverbindung bezüglich der Strom-/ Stoßstromtragfähigkeit bei fertigungstechnisch einfacher Geometrie, da der Erdkontakt als massives Teil ausgebildet sein kann. Die federnde Ausbildung der Einsteckzungen ist fertigungstechnisch mit einfachen Mitteln realisierbar. Zur Ausbildung der notwendigen Kontaktkräfte werden keine Kräfte in das Steckerinnere übertragen. Die auftretenden Spannungen werden hauptsächlich in den leistungsfähigen Federwerkstoffen der Sammelerde aufgenommen.For this purpose, the insertion tongues of the common earth are designed to be resilient, whereas the corresponding earth contact in the protective plug is arranged in a mechanically rigid manner in the plug housing. The geometry of the resilient insertion tongues is matched to the geometry of the earth contacts. Due to the rigid design of the earth contact in the protective plug, there is a simple assembly and automation capability in the manufacture of the protective plug, while at the same time high performance of the earth connection with regard to the current / surge current carrying capacity with simple manufacturing technology, since the earth contact can be designed as a solid part. The resilient design of the insertion tongues is technically feasible with simple means. For the formation of the necessary contact forces, no forces are transmitted into the interior of the connector. The stresses that occur are mainly absorbed in the high-performance spring materials of the collective earth.
In einer bevorzugten Ausführungsform sind die Funktionselemente und der Erdkontakt des Schutzsteckers auf einer Leiterplatte angeordnet, wodurch der Erdkontakt selbst nicht im Steckergehäuse abgestützt werden muß. Dadurch beeinträchtigen Maßschwankungen der Geometrie des Gehäuses oder Alterungsprozesse der verwendeten Kunststoffe für das Steckergehäuse nicht die verfügbaren Kontaktkräfte. Vorzugsweise wird der Erdkontakt auf der Unterseite der Leiterplatte angeordnet und als massiver Kontakt ausgebildet.In a preferred embodiment, the functional elements and the ground contact of the protective plug are arranged on a printed circuit board, so that the ground contact itself does not have to be supported in the plug housing. As a result, dimensional fluctuations in the geometry of the housing or aging processes of the plastics used for the connector housing do not impair the available contact forces. The earth contact is preferably arranged on the underside of the printed circuit board and designed as a solid contact.
Die korrespondierenden Einsteckzungen der Sammelerde sind dann vorzugsweise als Gabelkontakt ausgebildet, die den Erdkontakt seitlich federelastisch einspannen und kontaktieren.The corresponding insertion tongues of the collecting earth are then preferably designed as fork contacts, which clamp and contact the earth contact laterally in a resilient manner.
Zur Erzielung eines möglichst guten Kontaktes werden die Geometrien der Einsteckzungen und der Erdkontakte aufeinander abgestimmt. In einer bevorzugten Ausführungsform ist der Erdkontakt als massives, quaderförmiges Plättchen ausgebildet und der Gabelkontakt ist an den Kontaktstellen zu dem Erdkontakt kreisbogensegmentförmig ausgebildet. Ist hingegen der Erdkontakt kugel- oder zylinderförmig ausgebildet, so sind die Kontaktstellen der Gabelkontakte eben.To achieve the best possible contact, the geometries of the insertion tongues and the earth contacts are matched to one another. In a preferred embodiment, the earth contact is designed as a solid, cuboid-shaped plate and the fork contact is designed in the form of an arc segment at the contact points with the earth contact. However, if the earth contact is spherical or cylindrical, the contact points of the fork contacts are flat.
In einer weiteren bevorzugten Ausführungsform ist im Gehäuse eine zusätzliche Auflagefläche für die Leiterplatte angeordnet, so daß in dem gleichen Steckergehäuse verschieden bestückte und lange Leiterplatten verwendbar sind.In a further preferred embodiment, an additional contact surface for the printed circuit board is arranged in the housing, so that differently equipped and long printed circuit boards can be used in the same connector housing.
Das Steckergehäuse ist vorzugsweise in Längsrichtung zweigeteilt, wobei die beiden Gehäuseteile vorzugsweise miteinander verrastet werden. Durch die Längsteilung wirken beim Strecken und Ziehen des Schutzsteckers die Kräfte nicht in Richtung der Verbindung der Gehäuseteile.The connector housing is preferably divided in two in the longitudinal direction, the two housing parts preferably being locked together. Through the The longitudinal division does not act in the direction of the connection of the housing parts when the protective plug is stretched and pulled.
Die Unterteilung der Gehäuseteile erfolgt dabei vorzugsweise derart, daß ein erstes Gehäuseteil einen größeren Einbaubereich definiert, der im wesentlichen die auf der Vorderseite der Leiterplatte angeordneten Funktionselemente aufnimmt, wohingegen das zweite Gehäuseteil zur Aufnahme des Erdkontaktes dient. Daher ist auch der Einsteckkanal für die Einsteckzunge der Sammelerde im zweiten Gehäuseteil angeordnet. Diese unsymmetrische Aufteilung der Gehäuseteile bewirkt eine sehr kompakteThe housing parts are preferably subdivided in such a way that a first housing part defines a larger installation area which essentially accommodates the functional elements arranged on the front of the printed circuit board, whereas the second housing part serves to receive the ground contact. The insertion channel for the insertion tongue of the collecting earth is therefore also arranged in the second housing part. This asymmetrical division of the housing parts results in a very compact
Anordnung auf der Schalt- oder Trennleiste, so daß das Steckergehäuse nicht die Zugänglichkeit benachbarter Kontakte behindert.Arrangement on the switch or isolating strip, so that the connector housing does not hinder the accessibility of adjacent contacts.
In einer weiteren bevorzugten Ausführungsform ist in dem Steckergehäuse mindestens eine Meß- oder Trennstelle angeordnet, die vorzugsweise auf der Unterseite der Leiterplatte angeordnet und von der dem Einsteckteil abgewandten Seite von außen zugänglich ist. Vorzugsweise ist jeder Ader eine Meß- oder Trennstelle zugeordnet, wobei jedoch beide Meß- oder Trennstellen simultan durch einen Prüfstecker beschaltbar sind.In a further preferred embodiment, at least one measuring or separating point is arranged in the plug housing, which is preferably arranged on the underside of the printed circuit board and is accessible from the outside from the side facing away from the plug-in part. Each wire is preferably assigned a measuring or separation point, but both measuring or separation points can be connected simultaneously using a test plug.

Dieser Kontakt ist jeweils zwei Schneid - Klemm - Kontakten auf der Kabel- und Rangierseite der Schalt- oder Trennleiste 1 zugeordnet. Durch das Einstecken des Einsteckteiles 15 in diesem Kontakt werden die Schneid - Klemm-Kontakte elektrisch mit den Funktionselementen auf der Leiterplatte verbunden. Mit dem Einstecken des Einsteckteiles 15 dringt gleichzeitig die zugeordnete Einsteckzunge 10 in einen Einsteckkanal des Schutzsteckers 4 ein und kontaktiert einen Erdkontakt im Schutzstecker 4, was nachfolgend anhand von Fig. 2 erläutert werden soll. Dabei erfolgt die Kontaktierung des Erdkontaktes im Schutzstecker 4 zeitlich bevor die Funktionselemente mit den Schneid-Klemm-Kontakten verbunden werden, so daß stets eine sichere Erdverbindung der Funktionselemente vorhanden ist.The protective plug 4, in which, for example, overvoltage protection elements are arranged, comprises two housing parts 13, 14, in which a circuit board with the functional elements is arranged, a part of the circuit board protruding from the housing and forming an insertion part 15. This plug-in part 15 can be plugged into a contact (not shown) in the switching or isolating strip 1. This contact is in each case two insulation displacement contacts assigned to the cable and marshalling side of the safety or isolating strip 1. By inserting the plug-in part 15 in this contact, the insulation displacement contacts are electrically connected to the functional elements on the circuit board. When the plug-in part 15 is plugged in, the associated plug-in tongue 10 simultaneously penetrates into an insertion channel of the protective plug 4 and contacts an earth contact in the protective plug 4, which will be explained below with reference to FIG. 2. The contacting of the earth contact in the protective plug 4 takes place before the functional elements are connected to the insulation displacement contacts, so that there is always a secure earth connection of the functional elements.
In der Fig. 2 ist perspektivisch ein Teil der Sammelerde 3 mit aufgestecktem Schutzstecker 4 dargestellt, wobei zur besseren Darstellung des Kontaktierungsvorganges das Gehäuseteil 14 teilweise aufgebrochen ist. Die als Gabelkontakt ausgebildete Einsteckzunge 10 weist eine nach unten gerichtete Wölbung 16 auf, so daß die Oberseite des Gehäuseteiles 14 nahezu plan mit der Basis 8 der Sammelerde 8 abschließt, wodurch benachbarte Schalt- oder Trennleisten bei der Beschaltung nicht behindert werden. Des weiteren weisen die Einsteckzungen 10 eine leichte Wölbung 17 nach außen auf, wodurch die federnde Wirkung der Einsteckzunge 10 vergrößert wird. An den der Basis 8 abgewandten Seite weisen die Einsteckzungen 10 Kontaktstellen 18 auf, die den eigentlichen elektrischen Kontakt zu einem Erdkontakt 19 auf der Leiterplatte im Schutzstecker 4 herstellen. Die Kontaktstellen 18 sind nach innen kreisbogensegmentförmig ausgebildet. Beim Einstecken der Einsteckzunge 10 in den Einsteckkanal des Schutzsteckers 4 drücken die beiden Kontaktstellen 18 federnd gegen die planen Seitenwände des Erdkontaktes 19 und stellen somit einen mechanischen und elektrisch stabilen Kontakt her, wobei der Erdkontakt 19 mechanisch starr an der Leiterplatte befestigt ist. Dabei können die federnd ausgebildeten Kontaktstellen 18 sehr einfach mechanische Toleranzen des Erdkontaktes 19 bzw. der Leiterplatten oder des Gehäuses des Schutzsteckers 4 ausgleichen und einen sicheren elektrischen Kontakt gewährleisten. Wie leicht ersichtlich, kann die Güte des elektrischen Kontaktes zwischen den Kontaktstellen 18 und dem Erdkontakt 19 dadurch verbessert werden, indem deren Geometrien aufeinander abgestimmt werden. Wird beispielsweise der Erdkontakt 19 als stehender Zylinderstift ausgebildet, so werden die Kontaktstellen 18 vorzugsweise als plane Flächen ausgebildet.2 shows a perspective view of part of the collecting earth 3 with the protective plug 4 plugged in, the housing part 14 being partially broken open to better illustrate the contacting process. The tongue 10 formed as a fork contact has a downward curvature 16, so that the top of the housing part 14 is almost flat with the base 8 of the collecting earth 8, whereby adjacent switching or isolating strips are not hindered in the wiring. Furthermore, the insertion tongues 10 have a slight curvature 17 to the outside, whereby the resilient effect of the insertion tongue 10 is increased. On the side facing away from the base 8, the insertion tongues 10 have contact points 18 which make the actual electrical contact with an earth contact 19 on the printed circuit board in the protective plug 4. The contact points 18 are formed in the shape of an arc segment on the inside. When the insertion tongue 10 is inserted into the insertion channel of the protective plug 4, the two contact points 18 press resiliently against the flat side walls of the earth contact 19 and thus produce a mechanically and electrically stable contact, the earth contact 19 being mechanically rigidly attached to the printed circuit board. The resilient contact points 18 can very easily compensate mechanical tolerances of the earth contact 19 or the printed circuit boards or the housing of the protective plug 4 and ensure a safe electrical contact. As you can see The quality of the electrical contact between the contact points 18 and the earth contact 19 can be improved by coordinating their geometries with one another. If, for example, the earth contact 19 is designed as a standing cylindrical pin, the contact points 18 are preferably designed as flat surfaces.
Aus mechanischen Stabilitätsgründen ist das erste, einen größeren Einbauraum bildende Gehäuseteil 13 mit Sicken 20, 21 an den Seiten und der Rückseite ausgebildet. Weiter weist das Gehäuseteil 13 Öffnungen 22, 23 auf, in die komplementäre Rastnasen des zweiten Gehäuseteils einrastbar sind. Des weiteren ist auf der Rückseite des Schutzsteckers 4 ein Schlitz 24 vorhanden, über den eine optional vorhandene Trenn- oder Meßstelle auf der Leiterplatte durch einen Meß- oder Prüfstecker beschaltbar ist.For mechanical stability reasons, the first housing part 13, which forms a larger installation space, is formed with beads 20, 21 on the sides and the rear. Furthermore, the housing part 13 has openings 22, 23, into which complementary locking lugs of the second housing part can be snapped. Furthermore, there is a slot 24 on the rear side of the protective plug 4, via which an optionally available isolating or measuring point on the circuit board can be connected by a measuring or test plug.
In der Fig. 3 ist der Schutzstecker 4 ohne zweites Gehäuseteil 14 dargestellt. Auf einer Auflage des ersten Gehäuseteils 13 liegt eine Leiterplatte 25 auf, auf deren Unterseite mechanisch starr der Erdkontakt 9 angeordnet ist. Der Erdkontakt 19 ist entweder durch die Leiterplatte 25 durchgesteckt oder an einer Stelle elektrisch zur Oberseite durchkontaktiert und mit den Masseleitungen der auf der Oberseite angeordneten Funktionselemente, wie beispielsweise einem Uberspannungsableiter elektrisch verbunden. Das erste Gehäuseteil 13 ist mit Lagesicherungen 26 ausgebildet, die die Leiterplatte 25 zum Teil durchdringen und zum Gehäuseteil 13 fixieren.3, the protective plug 4 is shown without a second housing part 14. On a support of the first housing part 13 there is a printed circuit board 25, on the underside of which the earth contact 9 is arranged in a mechanically rigid manner. The earth contact 19 is either pushed through the printed circuit board 25 or electrically through-connected at one point to the top and electrically connected to the ground lines of the functional elements arranged on the top, such as a surge arrester, for example. The first housing part 13 is formed with position securing devices 26, which partially penetrate the circuit board 25 and fix it to the housing part 13.
In der Fig. 4 ist eine längere Leiterplatte 25 dargestellt auf der zusätzlich zwei Trennkontakte 27 angeordnet sind, die über den Schlitz 24 von außen beschaltbar sind.4, a longer circuit board 25 is shown on which two isolating contacts 27 are additionally arranged, which can be connected from outside via the slot 24.

Auf der Oberseite der Leiterplatte 25 sind ein Uberspannungsableiter 29, zwei PTC-Widerstände 30 und zwei Dioden 31 angeordnet, die einen Staffelschutz bilden. Auf der Unterseite der Leiterplatte 25 sind der Erdkontakt 19 und die beiden Trennkontakte 27 angeordnet. Der Erdkontakt 19 durchstößt die Leiterplatte 25 und ist mit dem Mittelabgriff 32 des Überspannunsableiters 29 elektrisch verbunden. Über eine Öffnung 33 ist der Erdkontakt 19 von außen zugänglich. Der Trennkontakt 27 ist im Bereich der Auflagefläche 37 fest mit der Leiterplatte 25 verbunden oder eingespannt. Zur Rückseite hin ist der Trennkontakt 27 gekröpft ausgebildet und über einen elektrischen Kontaktpad 34 der Leiterplatte 25 elektrisch leitend mit den Funktionselementen auf der Oberseite der Leiterplatte 25 verbunden. Der Trennkontakt 27 liegt dabei elektrisch hinter den Funktionselementen, so daß der Trennkontakt 27 gegen Überspannungen abgesichert ist. In dem zweiten Gehäuseteil 14 ist an der Stirnseite der Einsteckkanal 35 angeordnet, durch den die Einsteckzunge der Sammelerde in den Schutzstecker 4 eindringen kann. Die Leiterplatte 25 weist mehrere Durchbrüche auf, durch die die Lagesicherung 26 und verschiedene Rastmittel 36 des ersten Gehäuseteils 13 durchgreifen und eine Rastverbindung mit dem zweiten Gehäuseteil 14 bilden. Der aus dem ersten und zweiten Gehäuseteil 13, 14 herausragende Teil der Leiterplatte 25 bildet den Einsteckteil 15. Wie aus der Darstellung deutlich wird, sind alle stromführenden Teile über die Gehäuseteile 13, 14 nach außen hin isoliert.5 shows the protective plug 4 according to FIG. 4 with the second housing part 14 in cross section. The protective plug 4 comprises a first housing part 13, a second housing part 14 and the circuit board 25. The circuit board 25 rests on contact surfaces 28 of the housing part 13. On A surge arrester 29, two PTC resistors 30 and two diodes 31 are arranged on the upper side of the printed circuit board 25 and form a relay protection. The earth contact 19 and the two isolating contacts 27 are arranged on the underside of the printed circuit board 25. The earth contact 19 penetrates the circuit board 25 and is electrically connected to the center tap 32 of the surge arrester 29. The earth contact 19 is accessible from the outside via an opening 33. The isolating contact 27 is fixedly connected or clamped to the printed circuit board 25 in the region of the support surface 37. The isolating contact 27 is cranked toward the rear and electrically conductively connected to the functional elements on the upper side of the circuit board 25 via an electrical contact pad 34 of the circuit board 25. The isolating contact 27 is electrically behind the functional elements, so that the isolating contact 27 is protected against overvoltages. In the second housing part 14, the insertion channel 35 is arranged on the front side, through which the insertion tongue of the collecting earth can penetrate into the protective plug 4. The circuit board 25 has a plurality of openings through which the position securing means 26 and various latching means 36 of the first housing part 13 extend and form a latching connection with the second housing part 14. The part of the circuit board 25 protruding from the first and second housing parts 13, 14 forms the plug-in part 15. As is clear from the illustration, all current-carrying parts are insulated from the outside via the housing parts 13, 14.
