Abstract

The in-line electrical connector has two main parts in the form of a plug Ä3Ü and a socket Ä4Ü both of which have moulded sleeves Ä7,8Ü that are formed around grooves in the plug and socket bodies and so resist axial force. The pins of the plug are formed as metal pressings Ä10Ü and latch into axial holes. The socket contact bushes are also formed as pressings that fit into axial holes. The socket has a pair of finger pressure clamping elements Ä19Ü that engage lugs on the plug to resist axial force.

Description

Die Erfindung betrifft einen ein- oder mehrpoligen, gegen Spritzwasser geschützten Kabelstecker zum elektrischen Verbinden von Kabelenden, insbesondere als das eine Teil einer zweiteiligen Kupplung, mit einem Element zur Zugentlastung und mit einem die Anschlußstifte bzw. Anschlußbuchsen tragenden Gehäuse gemäß dem Oberbegriff des Anspruchs 1. Vorzugsweise besteht das Gehäuse aus einem einstückigen Kunststoff-Spritzteil.The invention relates to a single or multi-pole, against Splash-proof cable connector for electrical Connect cable ends, especially as one part a two-part coupling with an element for strain relief and with one the pins or sockets supporting housing according to the preamble of claim 1. Preferably there is Housing made from a one-piece molded plastic part.

Der Kabelstecker ist insbesondere für Spannungen bis zu 250 Volt und für Ströme bis zu 10 Ampere ausgelegt. Er ist insbesondere zur Verwendung innerhalb von Geräten mit dicht gepackten Einbauten und geringem noch freien Volumen, beispielsweise innerhalb von Gasthermen, vorgesehen.The cable connector is especially for voltages up to 250 volts and designed for currents up to 10 amps. He is especially for use within devices with tightly packed internals and little free space Volume, for example within gas heaters.

Beim Verlegen von Kabel ergeben sich oft Schwierigkeiten, wenn die Kabel mit ihren Steckern durch enge Öffnungen hindurchgeführt werden sollen. Angestrebt wird daher ein möglichst kleiner Außenquerschnitt der Kabelstecker. Bei der Erfüllung dieser Forderung stößt man jedoch an Grenzen, die zum einen durch die elektrischen Anforderungen entsprechend den VDE-Normen für Starkstrom bis zu 250 Volt Spannung und 10 Ampere Strom sowie durch die notwendige Zugentlastung und einen oft notwendigen Schutz der Kabelstecker und der damit hergestellten Kupplungen vor Spritzwasser vorgegeben sind.Difficulties often arise when laying cables when the cables with their plugs through narrow openings to be passed through. The aim is therefore one outside cross-section of the cable connector as small as possible. at however, the fulfillment of this requirement is triggered Limits, on the one hand, due to the electrical requirements according to the VDE norms for heavy current up to 250 Volt voltage and 10 ampere current as well as by the necessary Strain relief and an often necessary protection of the Cable connector and the couplings made with it Splash water are specified.

Insbesondere die Zugentlastung, die eine Beschädigung der Verbindung zwischen Stecker und Kabel beim nicht zulässigen Ziehen am Kabel selber anstatt am Stecker verhindern soll, führt zu relativ großen Querschnitten der Stecker. So bestehen aus dem Stand der Technik bekannte Elemente zur Zugentlastung aus verschraubbaren Klemmen. Zum Schutz vor Spritzwasser ist es außerdem bekannt, die Kabelstecker durch Verschrauben miteinander zu verbinden, wobei zur Abdichtung ein oder mehrere O-Ringe im Gehäuse der Stecker einliegen. Neben dem nachteiligen großen Außenquerschnitt ist hier in beiden Fällen ein relativ hoher Montageaufwand erforderlich. Ein weiterer Nachteil der aus dem Stand der Technik bekannten Stecker besteht in der Vielzahl von Einzelteilen, aus denen die Stecker kosten- und zeitintensiv hergestellt werden müssen.In particular the strain relief, which damage the Connection between plug and cable when not Prevent permitted pulling on the cable itself instead of the plug should lead to relatively large cross sections of the Plug. So there are known from the prior art Elements for strain relief from screwable clamps. To protect against splash water, it is also known that To connect the cable connector to each other by screwing, with one or more O-rings in the housing for sealing insert the plug. In addition to the disadvantageous large External cross section is a relative in both cases high assembly effort required. Another disadvantage the plug known from the prior art consists in the variety of items that make up the connector have to be manufactured costly and time-consuming.

Der Erfindung liegt daher die Aufgabe zugrunde, einen preiswert herzustellenden, nur geringen Montageaufwand bei der Verlegung der Kabel erfordernden, gegen Spritzwasser geschützten und für Spannungen bis zu 250 Volt sowie Ströme bis zu 10 Ampere ausgelegten Kabelstecker mit einem äußerst geringen Außenquerschnitt zu entwickeln.The invention is therefore based on the object inexpensive to produce, only little assembly effort the installation of the cables against splash water protected and for voltages up to 250 volts as well Currents up to 10 amps rated cable connector with a to develop an extremely small external cross-section.

Diese Aufgabe wird bei einem Kabelstecker der eingangs genannten Art durch die Merkmale des Anspruchs 1 gelöst.This task is the beginning of a cable connector Art solved by the features of claim 1.

Durch das Anspritzen wird das Zugentlastungselement stoffschlüssig sowohl mit dem Gehäuse als auch mit dem Kabel verbunden. Die Herstellung des Zugentlastungselements erfordert nur einen einzigen Arbeitsschritt und benötigt keine hochwertigen Einzelteile. Durch entsprechende Formgebung kann erreicht werden, daß das erfindungsgemäße Zugentlastungselement keinen größeren Außenquerschnitt als das Gehäuse aufweist. Im Gegensatz zum Stand der Technik erfüllt das erfindungsgemäße Zugentlastungselement auch die weitere Funktion eines absolut dichten Spritzwasserschutzes im Bereich des Kabelaustritts aus dem Gehäuse. The strain relief element becomes cohesive due to the injection molding with both the housing and the cable connected. The manufacture of the strain relief element requires only a single step and requires no high quality items. By appropriate shaping can be achieved that the invention Strain relief element no larger external cross section than has the housing. In contrast to the state of the art also fulfills the strain relief element according to the invention the further function of an absolutely watertight splash protection in the area of the cable exit from the housing.

Sowohl das Gehäuse als auch die Hülse besteht aus Polyamid. Beim Anspritzen des Zugentlastungselements wird die Hülse sowohl mit dem Gehäuse als auch mit der üblicherweise aus PVC bestehenden Außenisolierung des Kabels regelrecht verschweißt, so daß eine ausgesprochen stabile stoffschlüssige Verbindung und eine absolute Wasserdichtheit in diesem Bereich erreicht wird.Both the housing and the sleeve are made made of polyamide. When molding the strain relief element the sleeve is attached to both the housing and the Exterior insulation usually made of PVC Cable welded properly, so that one pronounced stable material connection and an absolute Watertightness is achieved in this area.

Weiterhin besteht die Hülse aus einem bei Drücken von höchstens 20 bar spritzbaren Kunststoff, damit besondere Aufwendungen zum Vermeiden von Schäden am Stecker durch erhöhte Spritzdrücke nicht notwendig sind.Furthermore, the sleeve consists of a Pressures of at most 20 bar sprayable plastic, thus special expenses to avoid Damage to the connector due to increased spray pressures is not necessary are.

Als vorteilhaft hat es sich herausgestellt, wenn die am Kabel anliegende Hülsenlänge, also die umspritzte Kabellänge, 16 bis 30 mm beträgt.It has proven to be advantageous if the on Cable adjacent sleeve length, i.e. the overmolded cable length, 16 to 30 mm.

Ferner beträgt die am kabelseitigen Ende des Gehäuses anliegende Hülsenlänge, also die umspritzte Länge des Gehäuses, vorzugsweise 8 bis 12 mm.It is also at the cable end of the housing adjacent sleeve length, i.e. the overmolded length of the Housing, preferably 8 to 12 mm.

Einen besonders effektiven Zugentlastungsschutz erhält man, wenn zusätzlich zur stoffschlüssigen Verbindung der angespritzten Hülse ein formschlüssiger Zusammenhalt mit dem Gehäuse vorgesehen ist. Daher wird in einer weiteren Ausgestaltung der Erfindung vorgeschlagen, daß das kabelseitige Ende des Gehäuses an seiner Außenseite Vertiefungen, insbesondere mindestens eine quer zur Kabelrichtung umlaufende Nut, aufweist.Receives particularly effective strain relief protection one, in addition to the cohesive connection of the molded sleeve with a positive cohesion the housing is provided. Therefore, in another Embodiment of the invention proposed that the cable side End of the housing recesses on its outside, in particular at least one transverse to the cable direction circumferential groove.

Eine erhöhte Sicherheit gegen ein Abrutschen der den Stecker ergreifenden Finger des Monteurs wird erreicht, wenn zumindest ein Teil der Außenseite der Hülse quer zur Kabelrichtung profiliert ist. Die eine Grifffläche bildenden Profile geben außerdem einen optischen Hinweis, daß der Stecker an dieser Stelle und nicht am Kabel selber zu ergreifen ist. Increased security against the slipping The fitter's finger gripping the plug is reached if at least part of the outside of the sleeve is transverse to the Cable direction is profiled. One grip area forming profiles also give a visual indication that the connector at this point and not on the cable itself is to be seized.

Vorzugsweise hat die Hülse im wesentlichen den gleichen Außendurchmesser wie das Gehäuse, so daß der erfindungsgemäße Kabelstecker insgesamt gerade den minimal erreichbaren Außendurchmesser aufweist, wenn die Pole, also die Anschlußstifte und Anschlußbuchsen, gerade die vorgeschriebenen Minimalabstände haben.Preferably the sleeve is substantially the same Outside diameter as the housing, so that the invention Overall cable connector just the minimum achievable Has outer diameter when the poles, so the pins and Connection sockets, just the prescribed minimum distances to have.

Die Erfindung betrifft auch eine zweiteilige Kupplung mit den genannten erfindungsgemäßen Kabelsteckern gemäß dem Anspruch 7.The invention also relates to a two-part clutch according to the mentioned cable connectors according to the invention claim 7.

Zum Schutz vor dem Eindringen von Spritzwasser in die aus den erfindungsgemäßen Kabelsteckern hergestellte Kupplung wird vorgeschlagen, daß das Gehäuse des die Anschlußstifte tragenden Kabelsteckers an seinem dem Kabel abgewandten Ende topfförmig ausgebildet ist, daß ein Dichtungsring, insbesondere ein aus Gummi bestehender O-Ring, an der inneren Kante zwischen Topfboden und Topfmantel einliegt und daß das Gehäuse des die Anschlußbuchsen tragenden Kabelsteckers eine Anlagefläche für den Dichtungsring aufweist.To protect against the ingress of splash water into the the coupling produced according to the invention it is proposed that the housing of the pins carrying cable connector on its facing away from the cable Is pot-shaped end that a sealing ring, especially a rubber O-ring on which inner edge between the bottom of the pot and the jacket of the pot and that the housing of the connector sockets Cable connector a contact surface for the sealing ring having.

Eine schnell und einfach herzustellende, gegen Spritzwasser geschützte Kupplung aus den erfindungsgemäßen Kabelsteckern wird durch mindestens eine bei miteinander verbundenen Kabelsteckern einrastende, einstückig mit den Gehäusen verbundene Verriegelung erreicht, die insbesondere lösbar ist.A quick and easy to manufacture, against splash water protected coupling from the invention Cable plugs are connected by at least one with each other connected cable connectors snapping in one piece with the Interlocking connected housing achieved that particular is solvable.

Die Verriegelung steht der Forderung nach einem möglichst geringen Außenquerschnitt des Gehäuses nicht entgegen, wenn die Verriegelung aus einer flächigen, parallel zur Außenseite des Gehäuses ausgerichteten Öse und einer entsprechenden Rastnase besteht.The lock stands for the demand for one if possible small outer cross-section of the housing, if the locking device consists of a flat, parallel to the Aligned outside of the housing and a corresponding There is a latch.

Ein einfaches Einrasten und Lösen der Verriegelung wird erreicht, wenn am kabelseitigen Ende der Öse eine Drucktaste angeformt ist und Öse und Drucktaste mittels eines zwischen ihnen liegenden Steges mit der Außenseite des Gehäuses verbunden sind.A simple snap and release of the lock will reached when there is a push button at the cable end of the eyelet is molded and eyelet and push button by means of a web between them with the outside of the Housing are connected.

Mit den erfindungsgemäßen Kabelsteckern läßt sich ein Stecksystem mit unterschiedlicher Polzahl und zusätzlicher unterschiedlicher Codierung aufbauen, wenn Nuten bzw. Federn am Boden und/oder an der Mantelinnenseite des topfförmigen Gehäuses und der daran im zusammengesteckten Zustand anliegenden Flächen des anderen Gehäuses zum Verhindern einer falschen Kupplungsverbindung vorgesehen sind. Zusätzlich wird durch das Nut-Feder-System auch ein Schutz gegen ein Verdrehen der komplementären Stecker erreicht.With the cable connectors according to the invention, one can Plug system with different number of poles and additional different coding if grooves or Feathers on the bottom and / or on the inside of the jacket Pot-shaped housing and the one plugged into it Condition of the surfaces of the other housing to prevent an incorrect coupling connection is provided are. In addition, the tongue and groove system also Protection against twisting of the complementary connector reached.

Ein weiterer Vorteil wird erzielt, wenn die Nuten bzw. Federn sich bis zum Öffnungsrand des Topfes und bis zur kupplungsseitigen Stirnfläche des die Anschlußbuchsen tragenden Gehäuses erstrecken. Nur bei passenden in der richtigen Drehstellung zueinanderliegenden Kabelsteckern läßt sich das männliche Kupplungsteil in das topfförmige Gehäuse einführen. Bei einer falschen Drehposition der beiden Kupplungsteile oder bei nicht zusammengehörenden Kupplungsteilen wird das Zusammenstecken schon vor dem Einführen blockiert, so daß die entsprechend tief im topfförmigen Gehäuse angeordneten Stifte auch bei einem gewaltsamen Versuch nicht verbogen werden.Another advantage is achieved if the grooves or Feather up to the opening edge of the pot and up to coupling-side end face of the connection sockets extend supporting housing. Only with suitable in the correct rotational position of the cable connectors can the male coupling part in the cup-shaped Insert housing. With an incorrect rotational position of the two coupling parts or if they do not belong together Coupling parts will be put together before Insert blocked, so that the corresponding deep in Pot-shaped housing arranged pins even with a violent attempt will not be bent.

Eine weitere Hilfe gegen das Zusammenstecken nicht zusammengehöriger Kupplungsteile wird durch eine unterschiedliche Farbgebung für die Gehäusetypen erreicht.No further help against plugging together related coupling parts is distinguished by a different Coloring achieved for the housing types.

Die zweiteilige, aus den Steckern nach den Figuren 1 und 2 zusammengesetzte Kupplung nach Figur 3 besteht aus zwei an Kabel 1, 2 angeschlossene Kabelstecker 3, 4. Jeder der beiden Kabelstecker ist aus einem vollständig aus Polyamid bestehenden spritzgegossenen zylindrischen Gehäuse 5, 6 und einem ebenfalls aus Polyamid bestehenden angespritzten Teil, der Hülse 7, 8 aufgebaut. Die Hülse besteht aus einem bei Drücken von höchstens 20 bar spritzbaren Kunststoff. Die Stifte sind mit dem Bezugszeichen 9, die Buchsen mit 10 bezeichnet.The two-part, from the plugs according to Figures 1 and 2 composite coupling according to Figure 3 consists of two Cable 1, 2 connected cable connector 3, 4. Each of the Both cable plugs are made entirely of polyamide existing injection molded cylindrical housing 5, 6 and a molded one, also made of polyamide Part, the sleeve 7, 8 built. The sleeve consists of a when pressing a maximum of 20 bar sprayable plastic. The pens are with the Reference numeral 9, the sockets designated 10.

Am kabelseitigen Ende sind in jedem der Gehäuse 5, 6 zwei parallele umlaufende Nuten 11, 12 eingeformt. Die als Anspritzteil ausgebildete Hülse erstreckt sich sowohl über diese Nuten 11, 12 als auch über das aus dem Gehäuse 5, 6 austretende Kabel 1, 2. Die angespritzten Hülsen 7, 8 sind massiv und weisen keine Hohlräume auf. Die umspritzte Kabellänge beträgt 30 mm. Das umspritzte Ende des Gehäuses hat etwa eine Länge von nur knapp 10 mm. Am kabelseitigen Ende der zylindrischen Hülsen 7, 8 sind quer zur Kabelrichtung verlaufende Profilierungen 13, 14 angebracht, die als Griffteil dienen und das Lösen der zweiteiligen Kupplung nach Figur 3 erleichtern.At the cable end there are two in each of the housings 5, 6 parallel circumferential grooves 11, 12 are formed. As Injection molded sleeve extends over both these grooves 11, 12 and also from the housing 5, 6 emerging cables 1, 2. The molded sleeves 7, 8 are massive and have no voids. The overmolded Cable length is 30 mm. The molded end of the case has a length of just under 10 mm. On the cable side End of the cylindrical sleeves 7, 8 are transverse to the cable direction extending profiles 13, 14 attached, the serve as a handle and release the two-part Lighten the coupling according to Figure 3.

Zum Spritzwasserschutz am steckseitigen Teil der Kabelstecker bzw. der zweiteiligen Kupplung ist ein O-Ring 15 in einer kreisförmigen Nut des die Anschlußstifte tragenden topfförmigen Kabelsteckers eingelegt, wobei die Kreisnut: die innere Kante zwischen Topfboden und Topfmantel bildet. Beim Zusammenstecken der zugehörigen Kabelstecker 3, 4 liegt die steckerseitige Stirnseite 16 des Buchsensteckers an diesem O-Ring 15 an.For splash water protection on the plug-in part of the cable connector or the two-part clutch is an O-ring 15 in a circular groove of the connector pins Cup-shaped cable connector inserted, the circular groove: the inner edge between the bottom of the pot and the jacket of the pot forms. When connecting the associated cable plugs 3, 4 is the plug end 16 of the socket connector on this O-ring 15.

Die gegen Spritzwasser geschützte Verbindung der beiden Kabelstecker 3, 4 wird durch eine Verriegelung gesichert, die aus zwei Ösen 17 und zwei Rastnasen 18 besteht, die in die entsprechenden Ösen eingreifen können, wie es in Figur 1 gezeigt ist. Damit wird eine feste und dauerhafte Verbindung der beiden Stecker erreicht. Zur Kabelseite hin sind die Ösen 17 verlängert, so daß sie in jeweils eine Drucktaste 19 auslaufen, die an ihrer Außenseite profiliert sind. Die Breite der Hülsen 17 mit ihren Drucktasten 19 beträgt etwa nur ein Drittel ihrer aus den Zeichnungen ersichtlichen Gesamtlänge. Zwischen der Hülse 17 und den Drucktasten 19 erstreckt sich ein Verbindungssteg 20, mit dem die Ösen und Drucktasten am Gehäuse 6 befestigt sind. Es sei noch einmal darauf hingewiesen, daß vorzugsweise das gesamte Gehäuse mit den Ösen 17, den Drucktasten 19 sowie dem Verbindungssteg 20 als ein einstückiges Kunststoffspritzgießteil hergestellt ist.The connection of the two protected against splash water Cable connector 3, 4 is secured by a lock, which consists of two eyelets 17 and two locking lugs 18 which in the corresponding eyelets can engage, as shown in Figure 1 is shown. This creates a firm and lasting connection of the two connectors reached. Towards the cable side the eyelets 17 are extended so that they are in one Pushbutton 19 leak on its outside are profiled. The width of the sleeves 17 with their push buttons 19 is about a third of theirs from the Drawings total length. Between the sleeve 17 and the push buttons 19 extends a connecting web 20, with which the eyelets and push buttons on the housing 6 are attached. It should be pointed out again that preferably the entire housing with the eyelets 17, Pushbuttons 19 and the connecting web 20 as one piece Plastic injection molded part is made.

Zum Lösen der Verriegelung wird auf die Drucktasten 19 gedrückt, so daß sich die Ösen 17 radial nach außen bewegen und die Rastnasen 18 aus den Ösen 17 freigeben.To release the lock, push buttons 19 pressed so that the eyelets 17 radially outward move and release the locking lugs 18 from the eyelets 17.

Um einen möglichst geringen Außenquerschnitt der gesamten zweiteiligen Kabelverbindung zu erreichen, springt die kabelseitige Außenfläche des Gehäuses 5 zurück, so daß eine umlaufende Schulter 21 entsteht.To have the smallest possible external cross-section of the entire to reach two-part cable connection, the jumps cable-side outer surface of the housing 5 back, so that a circumferential shoulder 21 is formed.

An der Stirnseite 16 und dem Topfboden 22 sind jeweils ein stegartiger bzw. eingenuteter dreistrahliger Stern 23, 24 angebracht, die beide nach den Nut-Feder-Prinzip zusammenwirken (Figuren 4 und 5). Sie haben zwei Funktionen. Zum einen begrenzen sie die zwischen den Stiften 9 bzw. Buchsen 10 eventuell entstehenden Kriechströme. Zum anderen verhindern sie im Zusammenwirken mit einer parallel an der äußeren bzw. inneren Mantelfläche verlaufenden Nut 25 bzw. Feder 26 das Zusammenkuppeln von nicht passenden Kabelsteckern und das Zusammenkuppeln von Kabelsteckern, die in unerwünschter Weise gegeneinander verdreht sind.On the end face 16 and the pot base 22 are each one web-like or grooved three-beam star 23, 24 attached, both of which work together according to the tongue and groove principle (Figures 4 and 5). They have two functions. To the one limit the between the pins 9 or Bushings 10 possibly occurring leakage currents. To the prevent others in cooperation with one parallel to the outer or inner lateral surface Groove 25 or spring 26 the coupling of mismatched cable connectors and the coupling of Cable connectors that undesirably oppose each other are twisted.

Das Nut-Feder-System der Sterne 23, 24 in Verbindung mit der Nut 25 und der Feder 26 ermöglicht den Aufbau eines mehrpoligen Kupplungssystems mit einer Sicherheit gegen eine falsche Verbindung. Zwei weitere Beispiele für dieses Stecksystem sind in den Figuren 6, 7 und 8, 9 dargestellt. Eine Vielzahl weiterer Ausführungen ist möglich. Zur Codierung ist weiterhin vorgesehen, daß nur die zueinander passenden Kabelstecker die gleiche Gehäusefarbe haben. The tongue and groove system of stars 23, 24 in conjunction with the groove 25 and the spring 26 enables the construction of a multipole coupling system with a security against a wrong connection. Two more examples of this Plug system are shown in Figures 6, 7 and 8, 9. A variety of other designs are possible. to Coding is also provided that only the one another matching cable connectors have the same housing color.
