Die Kontaktelemente weisen eine Steckseite auf, auf der sie mit einem The contact elements have a plug-in side on which they are connected to a
Gegensteckkontaktelement verbunden werden können. In Längsrichtung entgegengesetzt zur Steckseite, weisen sie eine Anschlussleitungsseite auf, an der beispielsweise durch Crimpen oder Löten eine Anschlussleitung befestigt werden kann. Die Anschlussleitungen werden dabei oftmals vorkonfektioniert, das heißt mit den Kontaktelementen verbunden, bevor die Kontaktelemente in das Steckverbindergehäuse eingesetzt werden. Das Einpressen der Kontaktelemente in die Durchstecköffnungen kann grundsätzlich sowohl von der Steckseite als auch von der Mating plug contact element can be connected. In the longitudinal direction opposite to the plug side, they have a connection line side to which a connection line can be attached, for example by crimping or soldering. The connection lines are often pre-assembled, that is, connected to the contact elements before the contact elements are inserted into the connector housing. The pressing of the contact elements into the through openings can in principle both from the plug-in side and from the
Anschlussleitungsseite her vorgenommen werden, wobei in jedem der beiden Fälle das Tannenbaumprofil am Kontaktelement eine dazu passende Connection line side are made, with the Christmas tree profile on the contact element matching in each of the two cases
Ausrichtung aufweisen muss. Must have alignment.
Das Einpressen von der Steckseite her ist im Allgemeinen einfacher, da der Gehäuseboden von dieser Seite her besser zugänglich ist. Nachteilig hierbei ist aber, dass vor dem Einpressen eines Kontaktelements vorher dessen bereits an diesem befestigte Anschlussleitung durch die zugehörige Pressing in from the plug-in side is generally easier because the housing base is more accessible from this side. The disadvantage here, however, is that before a contact element is pressed in, its connection line, which is already attached to it, is passed through the associated
Durchgangsöffnung gefädelt und gezogen werden muss. Dieses ist besonders bei Steckverbindern mit vielen Kontaktelementen und/oder langen The passage opening must be threaded and pulled. This is especially true for connectors with many contact elements and / or long ones
Anschlussleitungen umständlich und zeitaufwendig. Connection lines cumbersome and time-consuming.
Das Einpressen der Kontaktelemente der von der Seite der Pressing in the contact elements from the side of the
Anschlussleitungen her vermeidet ein Durchfädeln der Anschlussleitungen durch die Durchstecköffnungen. Nachteilig hierbei ist allerdings, dass der Gehäuseboden auf der Anschlussleitungsseite des Steckverbinders aufgrund der diesseitig zumeist größeren Länge des Steckverbindergehäuses für ein Werkzeug zum Einpressen der Kontaktelemente schlechter zu erreichen ist. Dieses gilt besonders dann, wenn der Steckverbinder hochpolig ausgeführt ist und daher eine große Anzahl von Kontaktelementen aufweist. Problematisch ist der Werkzeugeinsatz auch wegen der mit jedem bereits eingesetzten Kontaktelement steigenden Anzahl von Anschlussleitungen innerhalb des Steckverbindergehäuses, welche den Zugang des Werkzeugs weiter erschweren. Connecting lines prevents the connecting lines from being threaded through the through openings. The disadvantage here, however, is that the housing base on the connection line side of the connector is more difficult to reach for a tool for pressing in the contact elements due to the mostly greater length of the connector housing on this side. This is especially true when the connector has a high number of poles and therefore has a large number of contact elements. The use of tools is also problematic because of the increasing number of connection lines within the connector housing with each contact element already inserted, which makes access to the tool even more difficult.
Es stellte sich die Aufgabe, einen gattungsgemäßen Steckverbinder zu schaffen, der ein Einsetzen der Kontaktelemente von der The task arose of creating a connector of the generic type that allows the contact elements to be inserted from the
Anschlussleitungsseite des Steckverbindergehäuses her unter Vermeidung oder zumindest unter Verringerung der vorgenannten Nachteile ermöglicht. Connection line side of the connector housing while avoiding or at least while reducing the aforementioned disadvantages.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die According to the invention, this object is achieved in that the
Kontaktelemente jeweils zwischen dem Einpressabschnitt und dem Contact elements between the press-in section and the
Anschlussabschnitt einen Halterungsabschnitt aufweisen, und dass die Connection portion have a holding portion, and that the

Insertion collar 26 formed locking recess 27 (see Figures 5 and 6), whereby the position of the transverse slide 22 is then fixed on the plate 21. The assembly block 20 formed from plate 21 and cross slide 22 is used to fasten a plurality of contact elements 30.
Ein Kontaktelement 30 als Einzelteil zeigt die Figur 7. Das Kontaktelement 30 weist in Längsrichtung aufeinanderfolgend einen Kontaktabschnitt 31 , einen Einpressabschnitt 32, einen Flalterungsabschnitt 35 und einen A contact element 30 as an individual part is shown in FIG. 7. The contact element 30 has a contact section 31, a press-in section 32, a folding section 35 and a successively in the longitudinal direction
Anschlussabschnitt 34 auf. Connection section 34 on.
Der hier zylinderförmig ausgebildete Kontaktabschnitt 31 dient zum The cylindrical contact section 31 here is used for
Kontaktieren eines als Buchse ausgeführten Kontaktelements eines, hier nicht dargestellten, Gegensteckverbinders. Der Kontaktabschnitt kann auch, anders als hier dargestellt, alternativ als eine hülsenartige Kontaktbuchse ausgebildet sein, die entsprechend mit einem stiftartigen Kontaktelement eines Contacting a contact element designed as a socket of a mating connector, not shown here. The contact section can also, unlike shown here, alternatively be designed as a sleeve-like contact socket, which is correspondingly connected to a pin-like contact element
Gegensteckverbinders verbindbar ist. Mating connector is connectable.
Neben dem Kontaktabschnitt 31 befindet sich der Einpressabschnitt 32, welcher ein sogenanntes Tannenbaumprofil 33 aufweist. Dieses besteht aus mehreren aufeinanderfolgenden, in Längsrichtung konisch verlaufenden Anformungen. Das Tannenbaumprofil 33 ermöglicht dass Einpressen des Einpressabschnitt 32 in eine der Durchstecköffnungen 12 des Next to the contact section 31 is the press-in section 32, which has a so-called fir tree profile 33. This consists of several successive projections that run conically in the longitudinal direction. The fir tree profile 33 enables the press-in section 32 to be pressed into one of the push-through openings 12 of the
Steckverbindergehäuses 10 (Figur 4). Connector housing 10 (Figure 4).
Das Tannenbaumprofil 33 verjüngt sich in Richtung zum Kontaktabschnitt 31 , so dass das Einsetzen des Kontaktelements 30 in die Durchstecköffnung 12 mit dem Kontaktabschnitt 31 voran erfolgen kann. Dieses ist besonders vorteilhaft, da hierdurch bei mit Kontaktelementen 30 vorkonfektionierten Anschlussleitungen 40, die Anschlussleitungen 40 nicht in die Durchstecköffnungen 12 eingefädelt und hindurchgezogen zu werden brauchen, was bei einer Vielzahl von zu montierenden Kontaktelemente 30 und möglicherweise langen Anschlussleitungen 40 einen erheblichen zusätzlichen Montageaufwand verursachen würde. The fir tree profile 33 tapers in the direction of the contact section 31, so that the contact element 30 can be inserted into the push-through opening 12 with the contact section 31 first. This is particularly advantageous because it results in pre-assembled contact elements 30 Connection lines 40, the connection lines 40 do not need to be threaded into the push-through openings 12 and pulled through, which would cause considerable additional installation effort with a large number of contact elements 30 to be mounted and possibly long connection lines 40.
Der neben dem Einpressabschnitt 32 liegende Halterungsabschnitt 35 des Kontaktelements 30 besteht aus einen Abschnitt 37 mit einem relativ kleinen Durchmesser, der zu beiden Seiten jeweils von einem breiteren angeformten Kragen 36 begrenzt wird. Die Durchmesser der beiden Krägen 36 sind geringfügig kleiner als die Querschnitte der Durchgangsöffnungen 23 der Platte 21 und ebenfalls kleiner als die breitere Weite der Langlöcher 24 des Querschiebers 22. Gleiches gilt auch für den maximalen Durchmesser des Tannenbaumprofils 33. The holding section 35 of the contact element 30 lying next to the press-in section 32 consists of a section 37 with a relatively small diameter, which is delimited on both sides by a wider, molded collar 36. The diameters of the two collars 36 are slightly smaller than the cross sections of the through openings 23 of the plate 21 and also smaller than the wider width of the elongated holes 24 of the transverse slide 22. The same also applies to the maximum diameter of the Christmas tree profile 33.
Der Durchmesser des schmalen Abschnitts 37 zwischen den beiden KrägenThe diameter of the narrow section 37 between the two collars
36 ist dagegen etwas geringer als die schmalere Weite der Langlöcher 24 des Querschiebers 22. Zudem ist die Längserstreckung des schmalen Abschnitts36, however, is somewhat smaller than the narrower width of the elongated holes 24 of the transverse slide 22. In addition, the longitudinal extent of the narrow section is
37 ist geringer als die Materialdicke des Querschiebers 22. 37 is less than the material thickness of the cross slide 22.
Damit ist es möglich, die Kontaktelemente 30 in die Öffnungen des This makes it possible to insert the contact elements 30 into the openings of the
Montageblocks 20 einzuschieben, wenn die breiteren Abschnitte der Insert mounting blocks 20 if the wider sections of the
Langlöcher 24 der des Querschiebers 22 genau fluchtend zu den Elongated holes 24 of the cross slide 22 exactly aligned with the
Durchgangsöffnungen 23 der Platte 21 ausgerichtet sind. Dieser Through openings 23 of the plate 21 are aligned. This
Montagezustand ist in der Figur 8 dargestellt. The assembly state is shown in FIG.
Befinden sich die alle schmalen Abschnitte 37 der Kontaktelemente 30 dabei auf Höhe des Querschiebers 22, so kann der Querschieber 22 relativ zur Platte 21 verschoben werden, bis die schmalen Abschnitte der Langlöcher 24 an den schmalen Abschnitten 37 der Kontaktelemente 30 anliegen. In dieser Position des Querschiebers 22 verrasten dessen Rasthaken 28 mit den Rastausnehmungen 27 am Einschubkragen 26 der Platte 21. If all the narrow sections 37 of the contact elements 30 are at the level of the transverse slide 22, the transverse slide 22 can be moved relative to the plate 21 until the narrow sections of the elongated holes 24 rest against the narrow sections 37 of the contact elements 30. In this In the position of the transverse slide 22, its latching hooks 28 latch with the latching recesses 27 on the insertion collar 26 of the plate 21.
Die Kontaktelemente 30 sind damit nun durch den Querschieber 22 am Montageblock 20 arretiert, da die beiden Kragen 36 aller Kontaktelemente 30 sich jeweils beidseitig zu den schmalen Abschnitten der Langlöcher 24 des Querschiebers 22 befinden. Der damit hergestellte Montagezustand ist in der Figur 10 dargestellt. Die Figur 10 zeigt zudem, dass die Einpressabschnitte 32 der Kontaktelemente 30 aus dem Montageblock 20 hervorstehen. The contact elements 30 are thus now locked by the cross slide 22 on the assembly block 20, since the two collars 36 of all contact elements 30 are each located on both sides of the narrow sections of the elongated holes 24 of the cross slide 22. The assembly state thus produced is shown in FIG. FIG. 10 also shows that the press-in sections 32 of the contact elements 30 protrude from the mounting block 20.
Zur Montage des Steckverbinders wird der mit allen vorgesehenen To assemble the connector, the one provided with all
Kontaktelementen 30 bestückte Montageblock 20 mit dem Contact elements 30 equipped mounting block 20 with the
Steckverbindergehäuse 10 verbunden. Das in der Figur 4 als Einzelteil dargestellte Steckverbindergehäuse 10 besitzt senkrecht zu seiner Connector housing 10 connected. The connector housing 10 shown in Figure 4 as an individual part has perpendicular to its
Längserstreckung im Inneren einen Gehäuseboden 1 1 mit einer Vielzahl von Durchstecköffnungen 12, deren Anzahl und Anordnung derer der im Longitudinal extension inside a housing bottom 1 1 with a plurality of through openings 12, the number and arrangement of those of the in
Montageblockblock 20 vormontierten Kontaktelementen 30 entspricht. Mounting block block 20 corresponds to preassembled contact elements 30.
Die Weite der Durchstecköffnungen 12 ist auf die Querschnittsweite der Einpressabschnitte 32 der Kontaktelemente 30 abgestimmt, so dass sich die Kontaktelemente 30 jeweils durch Einpressen in die Durchstecköffnungen 12 am Gehäuseboden 1 1 fixieren lassen. The width of the push-through openings 12 is matched to the cross-sectional width of the press-in sections 32 of the contact elements 30, so that the contact elements 30 can be fixed in each case by being pressed into the through-opening 12 on the housing base 11.
Zur Montage der Kontaktelemente 30 wird der gesamte Montageblock 20 mit den daran vormontierten Kontaktelementen 30 von der Rückseite her an das Steckverbindergehäuse 10 angefügt, so dass die Kontaktabschnitte 31 der Kontaktelemente 30 in die Durchstecköffnungen 12 des Gehäusebodens 1 1 eintauchen. Diese Positionierung kann vorteilhafterweise durch am To assemble the contact elements 30, the entire assembly block 20 with the contact elements 30 preassembled thereon is attached to the connector housing 10 from the rear so that the contact sections 31 of the contact elements 30 dip into the through openings 12 of the housing base 11. This positioning can advantageously be carried out by am
Montageblock 20 und am Steckverbindergehäuse 10 angeformte Mounting block 20 and molded on the connector housing 10
Führungsnuten 61 und Führungsstege 15 unterstützt werden. Der Montageblock 20 wird danach kraftvoll an das Steckverbindergehäuse 10 angedrückt, so dass alle Einpressabschnitte 32 zugleich in die zugehörigen Durchstecköffnungen 12 eingepresst werden. Der Montageblock 20 verrastet in seiner vorgesehenen Endposition mit angeformten Rastvorsprüngen 29 im Inneren des Steckverbindergehäuses 10. Hiermit ist der in der Figur 3 skizzierte Montagezustand erreicht mit dem die Montage des Steckverbinders abgeschlossen ist. Guide grooves 61 and guide webs 15 are supported. The assembly block 20 is then pressed forcefully against the connector housing 10 so that all of the press-in sections 32 are pressed into the associated push-through openings 12 at the same time. The assembly block 20 latches in its intended end position with molded latching projections 29 in the interior of the connector housing 10. This achieves the assembly state outlined in FIG. 3 with which the assembly of the connector is completed.
Die Kontaktabschnitte 31 der in den Gehäuseboden 11 eingepressten The contact sections 31 are pressed into the housing base 11
Kontaktelemente 30 durchragen den Gehäuseboden 1 1 und sind daher, wie in der Figur 2 dargestellt, von der Vorderseite des Steckverbinders her zugänglich. Contact elements 30 protrude through the housing base 11 and are therefore, as shown in FIG. 2, accessible from the front of the connector.
