p0001Sealed connector by a partition and assembly processes

p0002The present invention relates to a plug connection for producing at least an electrical connection through an opening of a partition wall. The plug connection, which is also referred to as a through connector, has a first and a second plug which can be plugged together, and at least one of the plug is via an opening surrounding the seal against the partition wall can be sealed. Specifically, the present invention relates to a plug connection, wherein at least one of the plugs has a clamping device which is engageable with the other plug engages and with which the two connectors are permanently tensioned in their mating direction with inclusion of the partition wall. The invention further relates to an assembly method for manufacturing such an electric connector.

p0003In a known generic type connector, as shown for example in the published international patent application WO 2004/047234 A1, the tensioning of the two connectors is performed to one another with incorporation of the partition wall by means of a pusher which is approximately transverse to the tensioning of the two connectors in a direction towards the through-direction is displaced by the partition. Guide rails convert thereby the pushing force in a clamping force.

p0004However, in this known clamping device, the problem occurs that at the connecting points between the chuck and the plugs moisture can penetrate, which can lead to failure of the connector.

p0005The invention is therefore based on the object to improve a generic connector and an assembly method of the aforementioned type such that the density can be increased relative to the environment and the reliability of the connection.

p0006According to the present invention, this object is achieved by a connector having the features of claim 1. Furthermore, the object is achieved by a corresponding assembly method comprising the steps of the independent method claim.

p0007Furthermore, one of the present invention underlying task, one ne generic connector and an assembly method of the type mentioned to improve the effect that can be fixed in a very simple manner, at least one of the two connectors on the bulkhead and assembly errors can be easily detected.

p0008This object is achieved by a connector having the features of claim 27 and by a corresponding mounting method comprising the steps of claim 33rd

p0009Advantageous developments of the present invention are the subject of several dependent claims accident.

p0010The present invention is based on the fundamental idea that an undesirable ingress of moisture can be prevented in the interior of the connector characterized in that the connection area between the clamping device and the at least one connector is sealed by a sealing device.

p0011According to an advantageous embodiment the clamping device comprises at least one actuating projection which cooperates to tighten the connector with a receptacle that is arranged on one of the plug. In this manner can be carried out in a tension force in a very simple way, a translation of the expended during clamping force.

p0012In order to keep the area that such a sealing device needs to seal, as low as possible, the clamping device may comprise according to an advantageous embodiment a latch lever which is for clamping the two connector about a rotational axis which extends approximately transversely to the through-direction through the partition wall, pivotally , In such an arrangement it is sufficient to seal the area in which the lock lever rotatably mounted. In order to achieve a particularly effective force transmission of a pivoting movement into a clamping force for clamping the plugs, may be arranged with involute tooth flanks on the bearing projections as actuating projection respectively at least one tooth.

p0013According to an advantageous embodiment the clamping device comprises a locking lever having a base portion and two leg portions. _An The leg portions bearing projections are formed, which rules in corresponding Lagerausneh- of a plug rotatably mounted. In this way can be realized in a particularly simple manner that the locking lever for tensioning the plug about a rotational axis which extends approximately transversely to the through-direction through the partition is pivotable. The sealing device may then be placed on the bearing projections, for example in the form of an O-ring, or it is alternatively molded directly onto the bearing projections.

p0014A particularly inexpensive and simple embodiment of the sealing device according to the invention is given, when the sealing device is constituted by an elastic O-ring.

p0015The seal against the partition wall must be installed around the opening in the partition. According to an advantageous embodiment, the seal can be sprayed onto the outer periphery of the plug, so that the gasket is firmly attached to the connector housing. Moreover, the connection between the seal and the connector to which it is molded, always completely tight. However, this sealing also be a separate part which is engageable with both the plug and also with the partition wall in plant.

p0016In order to prevent unintentional loosening of the clamping device, a separate securing device TE, which is also referred to as a connector position assurance (CPA), may be provided for locking the tensioning device in a finally assembled state. In a particularly space-saving manner releasably is the security device, if they the through-direction through the partition is transversely displaceably in a direction.

p0017A latching lug which is provided for latching the clamping device to the securing device, is a particularly effective and easily realizable possibility of locking.

p0018As an alternative to the pivoting locking lever can also be used correspondingly off sealed sliding clamping device, which is for example useful if the available space to pivot the locked! rigs- lever does not allow during assembly. It may be a sliding device having at least one transmission or reduction arrangement, the jig. This allows converting an applied sliding force or movement in a greater or smaller clamping force or movement.

p0019Particularly advantageously, the clamping device may be a pusher, the _At tensioning of the connector in a direction approximately transverse to the feed-through direction by the partition wall displaceable. A particularly simple jig to plug connection is possible, the margins can be easy and is very fast and the installation space required can be kept low.

p0020In a further advantageous embodiment of the invention, the tensioning device may comprise at least one guide rail, which partially extends in a plane longer gs for mating direction and approximately transverse to the mating direction. Thus a sliding force or movement in a clamping force or movement is convertible.

p0021One sees a sealing device at an opening of a first connector housing through which emerges an engaging element of the clamping device, before, then a formed as a pusher jig against moisture penetration are particularly effectively sealed. Such a seal can, for example, be injection molded and improve the tightness even more complex cross-sections, eg., those having at least one sealing lip comprise.

p0022A particularly reliable and feasible with little effort seal can be achieved when at a second connector housing at least one sealing projection is formed, which cooperates for sealing the plug-in connection with the sealing device.

p0023Characterized in that further a locking device provided between a locked position in which the second connector is fixed on the partition wall, and an unlocked position wherein a particularly secure fixing of the second connector on the partition wall can be achieved. Such locking device as further connector position assurance (CPA) may be referred to, can be carried out so that a release is possible and in the case of the second plug repair can be easily removed from the partition. On the other hand, if greater forces must be expended during mating of the first connector, to ensure that the second connector is not accidentally released from the partition. , Is when this second plug ROS in a Ka kept serie sheet, particularly its rear side is accessible at the time of mating of not more readily, as is the case for example in a car door, can be avoided with the solution according to the invention that the second connector can no longer be contacted properly.

p0024Characterized in that the locking device is mechanically fixed in the unlocked position, a defined position of the latching device in the preassembled state to be ensured.

p0025It may further be disposed on the locking device at least one latch to secure the locking device in cooperation with a corre- sponding locking opening in the locked position. This is especially for applications in the automotive sector is important because here strong mechanical and thermal stresses occur during operation. Thus, the locking device can not move inadvertently out of the unlocked position, the at least one latch in the unlocked position can cooperate with a further associated latching opening, in order to fix the locking device in this position. Conveniently, these locking connection is accessible from the outside (at least for a suitable tool), so that it is in the case of a desired expansion solvable.

p0026The locking device can be displaced in the simplest case with respect to the second connector in mating direction of the connector. However, this solution has the disadvantage that it can not be ensured that the two connectors can only be plugged in, when the locking device is located correctly in its locked position. To ensure a particularly simple manner that the two connectors can only be plugged in when the second connector is in its final position in the opening of the partition wall and the locking device is properly locked, the locking device may be mounted on the second connector housing by means of a hinge-type connection and between the locked and the unlocked position by a swiveling movement around an axis approximately transversely to the through-direction through the partition wall extends to be movable.

p0027In such an embodiment may then be disposed in the second connector housing for example, a rotational axis of the opposite edge region in the unlatched state that the two connectors are not fitted together.

p0028Of course, the proposed in the context of the present tensioning device locking device can be used for other connections.

p0097A perspective view of the second connector 17 of Figure 17 is shown in the figure 18th Here, the second connector 17 is positioned in the partition wall 37, but not yet finally fixed. The locking device 102 is still in the pre-latching position. According to the present embodiment, the locking takes place here in the partition wall 37 exclusively via the elastic spring arm 152 and formed thereon the support structure 131 and on the opposing support structure 132. The locking device 102 holds, as will be apparent from the following Figure 19, in the locked definitively state the spring arm 1 52 in the locked position.

p0098In Figure 19, the connector 100 is shown in Figure 17 prior to mating of the first and second plugs 1, 17th The second connector 17 is firmly held in the partition wall 37 at this stage and the locking device 102 holds the spring arm 152 in the position shown. The first plug 1 is located in a steckbe- reϊten position at which the pusher 704 is locked in a pre-assembled position by means of the latching openings 224th

p0099Figure 20 shows the first connector 1 according to the embodiment shown in Figure 17 in a manner analogous to Figure 7 illustration. Essentially the explanations given with respect to the second embodiment apply equally to the embodiment shown in FIG 20th In particular, provided with circumferential seals 163 openings 72 and 73 and the functionality of the sliding device 704 correspond same as those of the second embodiment. As mentioned above, the pushing device has according to the present embodiment 704, latch hook 226 to be held securely in both a pre-latched position and in the final assembled position in the first plug housing second The first Pinaufnahrne 5 and the second pin recess 6 have a somewhat modified form. However, this configuration is only meant to be exemplary, as the P RINCIPLES invention can be used with any plug shapes used advantageously. Due to the recesses 218, the actuating surface 11 of the pushing device 704 may run linearly in the third embodiment, what the required installation space reduced.
