Description

Die Erfindung betrifft einen mehrpoligen wasserdichten Steckverbinder aus Kunststoff gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a multi-pole waterproof connector made of plastic according to the preamble of claim 1.

Ein derartiger Steckverbinder ist auf dem Markt(vgl. z. B. US-A-4 820 181). Nachteilig ist, daß der feste Sitz des Dichtungsrings mit einem zusätzlich zu montierenden Sicherungsring gewährleistet werden muß, damit der Dichtungsring seine vorgeschriebene Position einnimmt und beibehält. Des weiteren ist nachteilig, daß die Verriegelung der Kontaktelemente in den Kontaktelementgehäusekammern mit einem im Bereich des Dichtungsrings gelagerten Quer-Verriegelungsschieber erfolgt, der den Dichtungsring untergreift und der nur eine beschränkte räumliche Anordnung der Kontaktelementgehäusekammern, die er durchsetzen muß, im Gehäuse zuläßt, so daß eine freie Verteilung der Kontaktstellen im Steckverbinder eng begrenzt ist. Je nach Anordnung der Kammern kann eine Verriegelung nur mittels z. B. zweier Schieber erreicht werden. Die Anordnung des oder der Quer-Verriegelungsschieber verkompliziert die Raumform des Steckverbindergehäuses erheblich.Such a connector is on the market (see e.g. US-A-4 820 181). The disadvantage is that the tight fit of the sealing ring with an addition to mounting circlip must be ensured so that Sealing ring assumes and maintains its prescribed position. Another disadvantage is that the locking of the Contact elements in the contact element housing chambers with an im Area of the sealing ring mounted cross locking slide takes place, which engages under the sealing ring and which is only a limited one spatial arrangement of the contact element housing chambers, which he must enforce in the housing, so that a free Distribution of the contact points in the connector is narrowly limited is. Depending on the arrangement of the chambers, a lock can only by means of z. B. two sliders can be reached. The arrangement of the or the cross locking slide complicates the spatial shape of the connector housing considerably.

Außerdem setzen sich die Flanschränder 24 gegen den Dichtring 45 und bilden ein Gegenlager für den Dichtring. Während des Zusammendrückens der Gehäuse 1 und 2 gleitet der Rastbalken 21 in das Rastloch 43 und die Rastbalken 23 bewegen sich in Richtung Oberkante der Rastlöcher 44.After all contact elements 16 have been introduced into the contact element housing chambers 12 to 15, both housings 1 and 2 are pressed together in the final assembly position according to FIG. 4 the ring wall 3 forming an air gap for a catch overflow almost to the bottom of the annular gap 37 in front and the ends of the Locking pins 33, 34 slide over the inclined surfaces 18, the locking pins 33, 34 in the insertion opening 17th be pushed and in a manner known per se behind a locking edge a contact element 16 are brought. Furthermore put the flange edges 24 against the sealing ring 45 and form a counter bearing for the sealing ring. While squeezing the housing 1 and 2, the locking bar 21 slides into the Locking hole 43 and the locking bar 23 move in the direction of the upper edge the locking holes 44.

Die Erfindung kombiniert zum Abdichten eines Steckverbindergehäuses mit Verriegelungseinrichtung eine besondere, an sich bekannte Verriegelungseinrichtung mit zwei Gehäuseteilen und benutzt das Zusammenfügen der Gehäuseteile mit einer Vor- und einer Endmontagestellung zur Verriegelung der Kontaktelemente und zur Positionierung des Dichtrings 45. Die Montage des Steckverbinders ist dadurch sehr einfach und die Abdichtung gesichert, weil die Endmontagestellung eine definierte Abstützung für den Dichtring 45 schafft. Ein Verquetschen oder ungenügendes Lagern des Dichtrings ist nicht mehr zu befürchten. Die Verriegelungselemente sind außerhalb des Bereichs als Dichtung angeordnet.The invention combines to seal a connector housing with locking device a special, in itself known locking device with two housing parts and uses the joining of the housing parts with a pre and a final assembly position for locking the contact elements and for positioning the sealing ring 45. The assembly of the connector is very simple and the seal is secured, because the final assembly position is a defined support for the sealing ring 45. A crushing or insufficient There is no longer any fear of storing the sealing ring. The locking elements are arranged outside the area as a seal.
