After the hollow housing has been folded back into the floor pan, it is no longer possible to pull the individual plug heads out through the slots possible because the head diameter is larger than the slot width, so this intermediate connector provides increased security against accidental disconnection of plugs.

This not only simplifies the handling of the multiple connector; the multiple connector is also more stable overall with a simple construction. By simply repositioning the individual plug heads in the connecting piece (or inserting empty pieces), a differently combined compact plug results.

Description

Die Erfindung bezieht sich auf einen Mehrfachstecker mit einer Mehrzahl von an Kabel angeschlossenen Einzelsteckköpfen, von denen jeder wenigstens einpolig, vorzugsweise jedoch zweipolig, ausgebildet ist und die an einer entsprechenden Zahl von ein- oder mehrpoligen Gegenstücken an einem Gerät oder Zwischensteckteil ansteckbar sind, mit einem durch einen schwenkbaren Deckel verschliessbaren Verbindungsstück, das eine Mehrzahl von länglichen, parallelen Kammern mit Einlegöffnungen aufweist, in die die Einzelsteckköpfe gemäss der Anordnung der Pole der Gegenstücke am Gerät oder Zwischensteckteil einlegbar sind, und mit einer Verriegelung aus Quersteg und Nut, die die Einzelsteckköpfe jeweils in den Kammern gegen Herausfallen und Herausziehen sichert.The invention relates to a multiple plug with a plurality of individual plug heads connected to cables, each of which is at least single-pole, but preferably two-pole, and which can be plugged into a corresponding number of single-pole or multi-pole counterparts on a device or intermediate plug part, with a by means of a swiveling cover which can be closed and which has a plurality of elongated, parallel chambers with insertion openings into which the individual plug heads can be inserted according to the arrangement of the poles of the counterparts on the device or intermediate plug part, and with a locking device consisting of a crossbar and groove, which the individual plug heads each have secures in the chambers against falling out and pulling out.

Mehrfachstecker mit einer Mehrzahl von Einzelsteckköpfen sind bereits vielfach vorbekannt. Sie haben jedoch durchweg die Eigenschaft, dass sämtliche Einzelsteckköpfe einzeln am Gerät oder an einem Zwischensteckteil angesteckt werden müssen. So beschreibt beispielsweise der NDM-Prospekt «The Silvon Stress Test ECG Electrode System» 1977 einen Mehrfachstecker, bei dem Einzelsteckköpfe mit je einem dazugehörigen Signalkabel einzeln nebeneinander im Hohlgehäuse eines Zwischensteckteiles ansteckbar sind, das einen einzelnen Mehrfachkabelanschluss umfasst. Des weiteren wird durch den NDM-Prospekt («Silvon, Compare IT With Your Present Electrode System» 1978 ein ähnlicher Mehrfachstecker mit Zwischensteckteil angeboten, bei dem das Hohlgehäuse zur Aufnahme der Einzelsteckköpfe in einer Bodenwanne sitzt, die mit Einlegschlitzen an der Vorderwand für die Einzelkabel der Einzelsteckköpfe versehen ist. Durch Hochklappen des Hohlgehäuses lassen sich die Einzelsteckköpfe einzeln mit den Kabelanschlüssen in die Schlitze einlegen und zugleich die Steckverbindungen mit den Gegenstücken des Hohlgehäuses herstellen. Nach Rückklappen des Hohlgehäuses in die Bodenwanne ist ein Abziehen der Einzelsteckköpfe durch die Schlitze hindurch nicht mehr möglich, da der Kopfdurchmesser grösser ist also die Schlitzbreite. Diese Zwischensteckverbindung gibt also erhöhte Sicherheit gegen zufälliges Abziehen von Steckern.Multiple plugs with a plurality of individual plug heads are already widely known. However, they consistently have the property that all individual plug-in heads have to be individually plugged into the device or an intermediate plug-in part. For example, in 1977 the NDM brochure "The Silvon Stress Test ECG Electrode System" described a multiple connector, in which individual plug heads, each with an associated signal cable, can be plugged in side by side in the hollow housing of an intermediate connector that includes a single multiple cable connection. Furthermore, the NDM brochure ("Silvon, Compare IT With Your Present Electrode System" 1978) offers a similar multiple plug with an intermediate plug-in part, in which the hollow housing for receiving the individual plug-in heads sits in a floor pan that has insertion slots on the front wall for the individual cables By folding up the hollow housing, the individual plug heads can be inserted individually into the slots with the cable connections and at the same time the plug connections can be made with the counterparts of the hollow housing. After the hollow housing has been folded back into the floor pan, it is no longer possible to pull the individual plug heads out through the slots possible because the head diameter is larger than the slot width, so this intermediate connector provides increased security against accidental disconnection of plugs.

Dasselbe gilt auch für den Mehrfachstecker des Perena-Prospektes «Nouveau Standard ä Usage International Faisceaux ECG Electrodes», bei dem nach Anstecken der Einzelköpfe eine nach Art eines Kammes mit Schlitzen ausgebildete Klammer geschlossen wird, die die Einzelsteckköpfe wieder bei eingelegten Einzelkabeln gegen Herausziehen sichert.The same also applies to the multiple plug of the Perena brochure "Nouveau Standard ä Usage International Faisceaux ECG Electrodes", in which, after plugging in the individual heads, a clip designed in the manner of a comb with slits is closed, which secures the individual plug heads against being pulled out again when the individual cables are inserted.

Schliesslich ist durch den ARBO-Prospekt «Adapter und Patientenkabel» auch noch eine Rundsteckverbindung vorbekannt, bei der ein schuhartig ausgebildetes Zwischensteckteil im flachen Bodenteil für jeden Einzelsteckkopf vertikale Stecklöcher für am Einzelsteckkopf vertikal nach unten gerichtete Steckpole aufweist. Auch im Falle dieses Mehrfachsteckers müssen die Einzelsteckköpfe einzeln gesteckt werden.Finally, the ARBO brochure "Adapters and patient cables" also discloses a round plug-in connection, in which a shoe-like intermediate plug-in part in the flat bottom part has vertical plug-in holes for plug-in poles vertically downward on the individual plug-in head. In the case of this multiple plug, the individual plug heads must be plugged in individually.

Ein Mehrfachsteckverbinder der eingangs genannten Art, bei dem die Einzelsteckköpfe parallel zueinander gehalten werden, ist aus der GB-A-2024537 bekannt. Hierbei wird ein durch einen Deckel verschliessbares Verbindungsstück verwendet, bei dem der Deckel quer zur Längsrichtung der Kammern angebracht ist. Eine Querverbindung überdeckt damit permanent einen Teil der Kammern. Dadurch ist das Einbringen von Einzelsteckköpfen in die verbleibenden Einlegöffnungen von der Deckelseite her erschwert. Als Einzelsteckköpfe werden endseitig an Kabel angeschlossene Buchsen verwendet. Jede Buchse umfasst ein Frontteil mit einer nach aussen gerichteten Metallnase (Quersteg). Die Metallnase greift nach dem Einführen der Buchse in die zugeordnete Kammer in eine Quernut, die in der Kammerwand vorgesehen ist, federnd ein. Bei diesem Mehrfachsteckverbinder können die Einzelsteckköpfe nach Öffnen des Deckels ausgewechselt werden. Die Handhabung ist jedoch dabei recht kompliziert, da das Herausziehen der Buchsen in Längsrichtung der Kammern erfolgen muss. Die Buchsen sind dabei schlecht zu greifen. Die Auswechselbarkeit der Einzelsteckköpfe ist aber äusserst wichtig, damit z. B. im Falle eines Defekts an einem Einzelsteckkopf nicht das gesamte Kabelsystem mit Mehrfachstecker weggeworfen werden muss. Ein unkompliziertes Auswechseln ist aber dort erwünscht, wo technisch weniger Versierte (z. B. im Krankenhausbereich) diesen an sich einfachen Vorgang durchführen möchten. Auch ist darauf hinzuweisen, dass bei dem bekannten Stecker relativ kompliziert geformte Buchsen verwendet werden müssen, was bei den Herstellungskosten ins Gewicht fällt.A multiple connector of the type mentioned, in which the individual plug heads are held parallel to one another, is known from GB-A-2024537. Here, a connector that can be closed by a lid is used, in which the lid is attached transversely to the longitudinal direction of the chambers. A cross connection thus permanently covers part of the chambers. This makes it difficult to insert individual plug heads into the remaining insertion openings from the cover side. Sockets connected to the ends of the cables are used as individual plug heads. Each socket comprises a front part with an outward-facing metal nose (crossbar). After the bushing has been inserted into the associated chamber, the metal nose engages in a transverse groove provided in the chamber wall. With this multiple plug connector, the individual plug heads can be replaced after opening the cover. However, handling is quite complicated since the bushings must be pulled out in the longitudinal direction of the chambers. The sockets are difficult to grip. The interchangeability of the individual plug heads is extremely important. B. in the event of a defect in a single plug head, the entire cable system with multiple plugs does not have to be thrown away. An uncomplicated replacement is desirable, however, where technically less experienced people (e.g. in the hospital area) want to carry out this simple process. It should also be pointed out that in the known plug, relatively complicatedly shaped sockets have to be used, which is significant in terms of the production costs.

Aufgabe vorliegender Erfindung ist es, einen Mehrfachstecker in Form eines Kompaktsteckers anzugeben, der einfach herstellbar und hinsichtlich des Ansteckens an einem Gerät oder an einem Zwischensteckteil vereinfachte Handhabung bei hoher Anzahl an Kombinationsmöglichkeiten bezüglich des Vertauschens der Einzelsteckköpfe untereinander gestattet.The object of the present invention is to provide a multiple plug in the form of a compact plug which is simple to manufacture and, with regard to being plugged into a device or an intermediate plug-in part, simplifies handling with a high number of possible combinations with regard to the interchanging of the individual plug heads with one another.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass jeder Einzelsteckkopf die Form eines schmalen Stabes mit einem Kopfteil und einem hinteren Teil aufweist, wobei der hintere Teil im wesentlichen die Form eines schmalen Quaders mit rechteckigem Querschnitt besitzt, dass jede der Kammern an wenigstens einer Stelle eine senkrecht zur Einlegeöffnung verlaufende Querschnittsverengung aufweist, dass der hintere Teil jedes Einzelsteckkopfes ein Abdrucknegativ der jeweiligen Kammer mit einer entsprechend der Querschnittsverengung der Kammer senkrecht zur Einlegöffnung verlaufenden und zur Querschnittsverengung passenden Nut darstellt, so dass die hinteren Teile der Einzelsteckköpfe quer zur Längsrichtung in die Kammern form- und kraftschlüssig einsetzbar sind, wobei der Kopfteil jeweils aus dem Verbindungsstück herausragt. Beim Mehrfachstecker nach der Erfindung sind sämtliche Einzelsteckköpfe vor Anstecken an einem Gerät oder Zwischensteckteil bereits zu einem Kompaktstecker zusammengesteckt. Dieser Kompaktstecker wird dann in seiner Gesamtheit am Gerät oder am Zwischensteckteil angesteckt. Dies vereinfacht nicht nur die Handhabung des Mehrfachsteckers; der Mehrfachstecker wird bei einfachem Aufbau insgesamt auch stabiler. Durch einfaches Umstecken der Einzelsteckköpfe im Verbindungsstück (oder Zwischenstecken von Leerstücken) ergibt sich ein anders kombinierter Kompaktstecker. Damit ist auch höchstmögliche Variabilität in der Anpassung des Kompaktstekkers an unterschiedliche Bedingungen gegeben.The object is achieved according to the invention in that each individual plug head has the shape of a narrow rod with a head part and a rear part, the rear part essentially having the shape of a narrow cuboid with a rectangular cross section, in that each of the chambers has a perpendicular shape at at least one point Cross-sectional constriction running to the insertion opening has that the rear part of each individual plug head represents an impression negative of the respective chamber with a groove that runs perpendicular to the insertion opening and matches the cross-sectional constriction, corresponding to the cross-sectional constriction of the chamber, so that the rear parts of the individual plug heads form into the chambers transversely to the longitudinal direction. and can be used non-positively, the head part protruding from the connecting piece. In the multiple plug according to the invention, all the individual plug heads are already plugged together to form a compact plug before being plugged into a device or adapter. This compact connector is then plugged in its entirety on the device or on the adapter. This not only simplifies the handling of the multiple connector; the multiple connector is also more stable overall with a simple construction. By simply repositioning the individual plug heads in the connecting piece (or inserting empty pieces), a differently combined compact plug results. This also gives the greatest possible variability in adapting the compact plug to different conditions.

Weitere Vorteile und Einzelheiten eines Ausführungsbeispieles der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispieles anhand der Zeichnung in Verbindung mit den abhängigen Ansprüchen.Further advantages and details of an embodiment of the invention result from the following description of an embodiment with reference to the drawing in conjunction with the dependent claims.

Es zeigen:

  • Fig. 1 ein Ausführungsbeispiel der Erfindung in teilweiser Explosionsdarstellung,
  • Fig. 2 dasselbe Ausführungsbeispiel als fertiggesteckter Kompaktstecker, und
  • Fig. 3 und 4 modifizierte Anwendungsmöglichkeiten.
Show it:
  • 1 shows an embodiment of the invention in partial exploded view,
  • Fig. 2 shows the same embodiment as a compact plug, and
  • 3 and 4 modified applications.

In Fig. 1 sind insgesamt drei Einzelsteckköpfe I, II, III zu einem Kompaktstecker zusammensteckbar. Die Einzelsteckköpfe I, II und III haben die in der Fig. 1 dargestellte Form von schmalen Stäben. Das freie Kopfteil 1 eines jeden Stabes ist oben abgerundet; es beinhaltet an der Stirnfläche 2 eine zweipolige Steckbuchse 3. Der hintere Teil 4 des jeweiligen Stabes hat im wesentlichen (bis auf später noch zu beschreibende Nuten 15) die Form eines schmalen Quaders. An den hinteren Stabteilen 4 sind jeweils Signalkabel 5 angeschlossen. Die stabförmigen Einzelsteckköpfe I , 11, III sind mittels eines nach Art einer Manschette ausgebildeten Verbindungsstückes 6 zu einem Kompaktstecker zusammensteckbar. Das Verbindungsstück 6 umfasst dabei ein Bodenteil 7 mit Seitenwänden 8 und 9 und zwei Zwischenwänden 10 und 11. Die Seiten- und Zwischenwände 8, 9 bzw. 10, 11 unterteilen das Bodenteil 7 in insgesamt drei Kammern 12,13 und 14. Die Seitenwand 8 und auch die Zwischenwände 10 und 11 beinhalten an der Innenseite jeweils einen Quersteg 16. Dieser Quersteg 16 passt zu den eingangs erwähnten Nuten 15 der stabförmigen Einzelsteckköpfe I bis 111; beim Einlegen der Einzelsteckköpfe I, II und III in die Kammern 14, 13 bzw. 12 ergibt sich somit eine kraftschlüssige Nut-Steg-Verbindung zwischen den Kammern des Verbindungsstückes 6 und den eingelegten Einzelsteckköpfen. Ein unbeabsichtigtes Herausziehen oder Herausfallen von Einzelsteckköpfen I, II und III aus den Kammern 14,13 bzw. 12 ist unmöglich. Die Verbindung ist jedoch nicht nur kraftschlüssig, sie ist auch formschlüssig. Die stabförmigen Einzelsteckköpfe I bis III liegen nach dem Einstecken dicht in den Kammern 14, 13 bzw. 12. Es gibt somit auch keine Schmutzecken, die eine Verschmutzung zulassen würden. Auch nach Gesichtspunkten der Reinlichkeit ist die Kompaktsteckverbindung also günstig ausgestaltet. Die gute Stabilität des Kompaktsteckers wird noch erhöht durch einen Deckel 18, der an der Seitenwand 16 über eine Kippachse 17 angelenkt ist. Der Deckel 18 umfasst einen Rastvorsprung 19, der in eine Rastnut 20 des Bodenteiles 7 passt. Nach Schliessen des Deckels 18 ergibt sich die in Fig. 2 dargestellte fertige Steckform des Kompaktsteckers.In Fig. 1, a total of three individual plug heads I, II, III can be plugged together to form a compact plug. The individual plug heads I, II and III have the form of narrow rods shown in FIG. 1. The free head part 1 of each rod is rounded at the top; it includes a two-pole socket 3 on the end face 2. The rear part 4 of the respective rod has essentially the shape of a narrow cuboid (except for grooves 15 to be described later). Signal cables 5 are connected to the rear rod parts 4. The rod-shaped individual plug heads I, 11, III can be plugged together to form a compact plug by means of a connecting piece 6 designed in the manner of a sleeve. The connecting piece 6 comprises a bottom part 7 with side walls 8 and 9 and two partition walls 10 and 11. The side and partition walls 8, 9 and 10, 11 divide the bottom part 7 into a total of three chambers 12, 13 and 14. The side wall 8 and also the intermediate walls 10 and 11 each contain a cross bar 16 on the inside. This cross bar 16 fits the aforementioned grooves 15 of the rod-shaped individual plug heads I to 111; when inserting the individual plug-in heads I, II and III into the chambers 14, 13 and 12, there is thus a force-locking groove-web connection between the chambers of the connecting piece 6 and the inserted single plug-in heads. An unintentional pulling out or falling out of individual plug heads I, II and III from the chambers 14, 13 and 12 is impossible. However, the connection is not only non-positive, it is also positive. The rod-shaped individual plug heads I to III lie tightly in the chambers 14, 13 and 12 after being plugged in. There are therefore also no dirt corners which would allow contamination. In terms of cleanliness, too, the compact plug connection is designed to be inexpensive. The good stability of the compact connector is further increased by a cover 18 which is articulated on the side wall 16 via a tilt axis 17. The cover 18 comprises a locking projection 19 which fits into a locking groove 20 of the bottom part 7. After closing the cover 18, the finished plug shape of the compact plug shown in FIG. 2 results.

Dieser Kompaktstecker, der als Baueinheit an entsprechenden Gegenstücken eines Gerätes oder eines Zwischensteckteiles ansteckbar ist, ist nicht nur besonders einfach in der Handhabung des Ansteckens. Er gewährleistet auch hohe Variabilität in der Anpassung an unterschiedliche Bedingungen, wie z.B. in den Fig. 3 und 4 dargestellt ist. Fig. 3 zeigt den Kompaktstecker mit einer Schichtung der Einzelköpfe I, II, III in einer solchen Reihenfolge, dass er zu Gegenkontakten ST I, ST II, ST III eines Gerätegegensteckers oder Zwischensteckteiles 21 passt. Bei modifizierter Ausbildung des Gerätegegensteckers oder des Zwischensteckteils 21 mit z.B. geänderter Reihenfolge der Gegenpole der Gegenstücke lässt sich der Kompaktstecker durch einfache Umordnung der Einzelsteckköpfe I, II und III (oder Weglassen einzelner Steckköpfe oder Zwischenschaltung von Leerstücken) an die neuen Gegebenheiten anpassen. In Fig. 4 ist beipielsweise eine solche Umordnung entsprechend der Reihenfolge III, I, II passend zu Gegenkontakten ST III, ST I, ST II an einem Gegensteckstück 22 dargestellt.This compact plug, which can be plugged in as a structural unit on corresponding counterparts of a device or an intermediate plug-in part, is not only particularly easy to handle when plugging in. It also ensures high variability in adapting to different conditions, e.g. 3 and 4 is shown. Fig. 3 shows the compact connector with a stratification of the individual heads I, II, III in such an order that it fits to mating contacts ST I, ST II, ST III of a device mating connector or adapter 21. With a modified design of the device mating connector or the intermediate plug part 21 with e.g. changed the order of the opposite poles of the counterparts, the compact connector can be adapted to the new conditions by simply rearranging the individual plug heads I, II and III (or omitting individual plug heads or interposing empty pieces). In Fig. 4 such a rearrangement is shown according to the order III, I, II matching mating contacts ST III, ST I, ST II on a mating connector 22.

Im Ausführungsbeispiel umfasst der Kompaktstecker insgesamt drei Einzelsteckköpfe I, II und III. Dies ist jedoch lediglich exemplarisch. Selbstverständlich sind Kompaktstecker mit einer anderen Anzahl von Einzelsteckköpfen, also auch mit z.B. zehn Einzelsteckköpfen oder noch mehr, möglich. Die kopfseitig abgerundeten Stäbe I, II, III können auch andere Kopfgestalt aufweisen. Wesentlich ist, dass die Kopfgestalt der Einzelsteckköpfe I, II, III passend zur Gestalt der Gegenstücke ausgebildet ist, wodurch zusätzlich erhöhte Sicherheit beim Anstecken des Kompaktsteckers gewonnen wird. Es ist dann nicht nur gewährleistet, dass die vom Kompaktstecker vorgegebene richtige Reihenfolge der Einzelsteckköpfe I, II, III zur Reihenfolge der Gegenstücke ST I, ST II, ST III am Gerät oder Zwischensteckteil passt; auch hinsichtlich der bereits vorgegebenen Reihenfolge schliesst die besondere Fomgestalt der Kopfteile 1 der Einzelsteckköpfe I, II, III ein fehlerhaftes Anschliessen der gesamten Reihe, z.B. aufgrund unerwünschter 180°-Drehung, ebenfalls mit Sicherheit aus.In the exemplary embodiment, the compact plug comprises a total of three individual plug heads I, II and III. However, this is only an example. Of course, compact plugs with a different number of individual plug heads, i.e. also with e.g. ten individual plug heads or even more possible. The rods I, II, III rounded on the head side can also have a different head shape. It is essential that the head shape of the individual plug heads I, II, III is designed to match the shape of the counterparts, as a result of which additional security is gained when the compact plug is plugged in. It is then not only guaranteed that the correct order of the individual plug heads I, II, III specified by the compact plug matches the order of the counterparts ST I, ST II, ST III on the device or intermediate plug part; also with regard to the sequence already specified, the special shape of the head parts 1 of the individual plug-in heads I, II, III prevents incorrect connection of the entire row, e.g. due to undesired 180 ° rotation, also with certainty.

Die nebeneinander angeordneten Pole der Einzelsteckköpfe bzw. auch Gegenstücke können selbstverständlich auch nach Art eines Koaxialsteckers angeordnet sein.The adjacent poles of the individual plug heads or counterparts can of course also be arranged in the manner of a coaxial connector.

Claims (3)

1. A multiple connector comprising a plurality of individual connector heads (I, II, III) which are connected to cables (5) and each of which is at least unipolar, but is preferably bipolar, and which can be connected to a corresponding number of unipolar or multipolar counter-pieces (STI, STII, STIII) on an apparatus or intermediate connector member (21, 22), a connecting member (6) which can be closed by a pivotable cover (18) and which has a plurality of elongated, parallel chambers (12, 13, 14) with insertion openings into which the individual connector heads (I, II, III) can be inserted in conformance with the poles of the counter-pieces (STI, STII, STIII) on the apparatus or the intermediate connector member (21, 22), and a transverse rib (16) and groove (15) locking mechanism which secures the individual connector heads (I, II, III) in the respective chambers (12, 13, 14) from falling out and withdrawal, characterised in that each individual connector head (I, II, III) is in the form of a slender rod having a head part (1) and a rear part (4), the rear part (4) essentially having the shape of a narrow parallelepiped with a rectangular cross-section; that each of the chambers (12, 13, 14) has, at least at one point, a reduction in cross-section (16) which extends at right angles to the insertion opening; that the rear part (4) of each individual connector head (I, II, III) represents a negative counterpart of the respective chamber (12, 13, 14) with a groove (15) which matches the reduction in cross-section and extends at right angles to the insertion opening in correspondance with the cross-sectional reduction (16) of the chamber (12, 13, 14), so that the rear parts (4) of the individual connector heads (I, II, III) can be inserted into the chambers (12,13,14) so as to be form-locking and force-locking transversely to the longitudinal direction, the head part (1) protruding from the connecting member (6) in each case.
2. A multiple connector as claimed in Claim 1, characterised in that the head parts (1) which protrude from the chambers (12, 13, 14), have a shape (2) which corresponds to the shape of the counter-pieces.
3. A multiple connector as claimed in Claim 1, characterised in that the head parts (1) are rounded on at least one side.
