Definitions

  • the present invention relates to a housing assembly for an electrical connector with an operating lever, for example, but not exclusively, for automotive applications.
  • the present invention relates to an electrical connector with such a housing assembly and to a connector assembly with an electrical plug.
  • electrical connectors are used in electric circuits for establishing releasable plug connections for transmitting electrical currents and/or signals between components belonging to the electric circuit.
  • it may possibly be necessary to overcome substantial resisting forces, which impedingly counteract the mating process.
  • it is advisable to make use of a manually operated mating assistance system for mechanically assisting the mating process in automotive engineering, inter alia.
  • the entire mechanism of the mating assistance system may be arranged fully on the outside of the electrical connector, so as not to affect the tightness of the electrical connector, but, being located there, it takes up a correspondingly large amount of installation space.
  • parts of the mechanism may be integrated inside the electrical connector, but, for the purpose of manual operation, they must be operatively connected to the outside of the electrical connector, and this will inevitably result in leakage.
  • a housing assembly for an electrical connector that is intermateable with a mating connector along a mating direction, comprising a connector housing and an operating lever pivotably arranged on the connector housing, wherein the operating lever has at least one drive element which is arranged such that it can be brought into engagement with the mating connector, wherein the operating lever has at least one lever arm which is provided with a bearing journal, wherein the connector housing has at least one bearing hole having inserted therein the bearing journal of the at least one lever arm, and wherein at least one bearing seal is arranged between the connector housing and the bearing journal of the at least one lever arm.
  • the present invention is advantageous because the operating lever serves the purpose of assisting the mating process due to the presence of the at least one drive element and also contributes to the tightness due to the arrangement of the bearing journal in relation to the connector housing and the at least one bearing seal.
  • This functional integration at the operating lever allows the housing assembly according to the present invention to be configured in a space-saving and at the same time sealed manner.
  • the connector housing may be an injection molded plastic part so as to save costs and/or weight, the at least one bearing hole being e.g. a substantially circular through-hole, which leads into the interior of the connector housing, preferably perpendicular to the mating direction, and which is formed in the course of the injection molding process.
  • the at least one bearing hole may be a bearing bore, preferably a deburred bearing bore.
  • the at least one bearing hole may have provided therein a bearing bush.
  • the operating lever may act as an actuation lever, an activation lever and/or an assistance lever and be part of a mating assistance system for assisting a mating process and/or a separation process between the electrical connector and the mating connector.
  • the at least one lever arm may have a lever flank so as to produce a leverage effect, the bearing journal being formed at one end of this lever flank.
  • the bearing journal may be an axle journal or a pivot pin with a cylindrical or plug-shaped portion that fits into the at least one bearing hole. In the inserted condition, the bearing journal can form a sealing connection with the at least one bearing seal and thus seal the at least one bearing hole tightly, preferably in a waterproof or at least in a dustproof and/or dirtproof manner.
  • the bearing journal and the bearing hole can form together a hole bearing, a rotary bearing, a sliding bearing or a tribological pairing with cylindrical contact surfaces.
  • the operating lever can thus be connected to the connector housing such that it is pivotable about a non-varying pivot axis, which preferably extends perpendicular to the mating direction.
  • the at least one drive element may be rotatable about the pivot axis in the interior of the connector housing.
  • the at least one drive element may be formed on the bearing journal of the at least one lever arm, preferably on a side of the bearing journal facing away from the respective lever flank.
  • the at least one drive element may be configured as an externally toothed gear element.
  • the at least one drive element may include a segment or a section of a gear, a gear rim, an annular gear or a gearlike shaped portion.
  • the at least one bearing seal may be located between the at least one drive element and the at least one lever arm.
  • at least one bearing seal may be located between the drive element and the lever flank.
  • the drive element and the lever arm, in particular the lever flank can be arranged on respective opposite sides of the at least one bearing seal.
  • the at least one lever arm, in particular its lever flank may be arranged outside on the connector housing, while the at least one drive element is accommodated inside the connector housing. This allows a compact structural design of the housing assembly in the direction of the pivot axis.
  • the at least one bearing seal may, according to a further embodiment, form together with the connector housing a two-component part produced by two-component injection molding.
  • the at least one bearing seal may be injection molded into the at least one bearing hole.
  • the at least one bearing seal can thus be formed together with the connector housing in one and the same manufacturing process, without any additional mounting steps being necessary.
  • the bearing journal of the at least one lever arm may also be overmolded with the at least one bearing seal. Accordingly, the at least one bearing seal will then form a two-component part with the operating lever and will abut, in this case, on an inner wall of the connector housing in the at least one bearing hole.
  • the at least one bearing seal may be a prefabricated separate sealing ring, which is either inserted into the at least one bearing hole or attached to the bearing journal of the at least one lever arm. This will improve a replaceability of the at least one bearing seal in the event that repair should be necessary.
  • the connector housing may have two bearing holes according to a further possible embodiment, each bearing hole being configured in accordance with the above description.
  • the two bearing holes may be arranged on two opposite sides of the connector housing, preferably such that they are in alignment along the pivot axis.
  • the operating lever may have two lever arms, each lever arm being configured in accordance with the above description.
  • the two lever arms may each be provided with a bearing journal; preferably, the bearing journals face each other and are arranged in an aligned manner along the pivot axis.
  • the each of the two lever arms may be inserted with its bearing journal into one of the two bearing holes.
  • the housing assembly has two bearing seals, each bearing seal being arranged between the connector housing and a respective one of the bearing journals.
  • each bearing hole may be provided for a particular lever arm and its bearing journal. Accordingly, each lever arm with its bearing journal can be inserted only into the bearing hole provided therefor. Alternatively, each of the two lever arms may be inserted with its bearing journal into an arbitrary bearing hole.
  • the operating lever may be configured in a U-shape.
  • the two lever arms may engage around the connector housing. This arrangement results in a symmetrical distribution of forces and thus improves the operability.
  • the operating lever may be a multipart component.
  • the advantage of this embodiment can be seen from the following consideration: a one-piece U-shaped operating lever would have to be elastically spread, so as to allow the bearing journals of its two lever arms to be inserted into the respective bearing holes, and would therefore have lever arms that are oversized in length.
  • there is no need to oversize the lever arms for reasons of flexibility in the case of a multipart operating lever, whereby a comparatively compact structural design of the operating lever perpendicular to the pivot axis will be possible.
  • the two lever arms may be configured to be joined, preferably to be joined repeatedly and/or in a form fit manner, so as to form a structural unit.
  • freely projecting ends of the two lever arms which face away from the respective bearing journals, may be plugged into each other, preferably parallel to the pivot axis.
  • each bearing journal into the respective bearing hole parallel to the pivot axis by a linear movement.
  • linear movement is here intended to describe that the movement in question is a purely translational movement which does not involve any pivoting or rotation. The linear movement primarily protects the bearing seals, which could easily be damaged by tilting and/or wedging of the bearing journal in the course of a pivoting movement of the lever arms.
  • the two lever arms may be configured to be separable from each other, preferably in a non-destructive manner or at least repeatedly.
  • each bearing journal can, if necessary, also be linearly pulled out of the respective bearing hole, which will simplify repair, by way of example.
  • the operating lever may be a three-part component.
  • the operating lever may comprise a removable connecting element via which the two lever arms are connectable.
  • the connecting element is a separate component, which connects the two lever arms in a bridge-like manner.
  • the two lever arms can thus be mounted on the connector housing independently of one another and can, subsequently, be connected by the connecting element.
  • the bearing journals of the two lever arms can be inserted independently of one another into the respective bearing hole parallel to the pivot axis.
  • the connecting element may have a handle, an operating handle, a handhold, a bracket and/or a portion with a gripping surface.
  • the connecting element can be attached to the respective freely projecting ends of the lever arms perpendicularly or tangentially to the pivot axis.
  • the two lever arms may each have a T-shaped profiled edge at their freely projecting ends, which can be accommodated in a respective T-shaped groove guide of the connecting element.
  • the connecting element may be fixed to the freely projecting ends of the two lever arms, e.g. by a locking connection.
  • the connecting element may also be glued, screwed, welded and/or pressed. This will avoid an unwanted movement relative to the lever arms and prevent loss of the connecting element.
  • the housing assembly may be provided with a securing device by means of which the at least one lever arm is prevented from being attached to and/or removed from the connector housing outside a mounting position, and by means of which the at least one lever arm is secured in position on the connector housing, when the at least one lever arm is attached to the connector housing and moved away from the mounting position.
  • the mounting position results here from a relative position between the at least one lever arm and the connector housing.
  • the securing device may be arranged partly on the connector housing and partly on the at least one lever arm.
  • the securing device may be of a bayonet-type design and have a flange on the connector housing for each bearing hole of the connector housing, said flange extending at least sectionwise around the respective bearing hole in the circumferential direction of the bearing hole in question.
  • the securing device may have at least one cam on each lever arm, said cam engaging behind the respective flange in a form-fit manner. In order to allow this, the at least one cam may project from an extension arm of the lever arm in the direction of the bearing journal.
  • the at least one lever arm is releasable from the connector housing at the mounting position.
  • the at least one lever arm is attachable to the connector housing and releasable from the connector housing exclusively at the mounting position.
  • each flange of the securing device may be provided with a gap at a fixedly defined location corresponding to the mounting position, the at least one cam of the securing device fitting through this gap when the lever arm, which is at the mounting position, is being mounted.
  • the mounting position may be a discrete angular position or a continuous angular area.
  • each lever arm may have a plurality of cams.
  • the flange may have a corresponding number of gaps.
  • the at least one lever arm may have an insertion position resulting from the position relative to the connector housing. At the insertion position of the at least one lever arm, the at least one drive element of the operating lever abuts on the mating connector, without being in engagement with the mating connector.
  • the electrical connector can thus be attached to the mating connector and detached from the mating connector.
  • the at least one lever arm can be pivoted from the mounting position to the insertion position at least during the mounting process.
  • the at least one lever arm may have a final mating position resulting from the position relative to the connector housing. At the final mating position of the at least one lever arm, the at least one drive element of the operating lever is in engagement with the mating connector. This condition corresponds to an electrical connector fully mated with the mating connector.
  • the at least one lever arm can be pivoted from the mounting position to the final mating position at least during the mounting process.
  • the at least one lever arm In the course of the mating process between the electrical connector and the mating connector, the at least one lever arm is moved from the insertion position to the final mating position. During the separation process of the electrical connector from the mating connector, the at least one lever arm is moved from the final mating position to the insertion position.
  • the mounting position may be located outside the area between the insertion position and the final mating position, including the insertion position and the final mating position. In other words, the mounting position is not located in the area between the insertion position and the final mating position, including the insertion position and the final mating position.
  • the at least one lever arm may lockingly engage with the connector housing at the final mating position.
  • the at least one lever arm may have a locking element, which establishes a locking connection with a locking edge of the connector housing.
  • the connector housing may have a locking aperture in which the locking element is locked in position.
  • the locking element may be formed on a flexible bar portion of the at least one lever arm.
  • the at least one lever arm may be provided with a push button. When this push button is actuated, the flexible bar portion will be deflected, so that the locking element will be moved out of the locking aperture on the connector housing.
  • the multipart operating lever can form a stop, when the lever arms are joined and moved away from the respective mounting position, the stop blocking a movement of the joined lever arms to the respective mounting position.
  • the connecting element may form this stop.
  • the connecting element can prevent the two lever arms from reaching, in a condition connected by the connecting element, the mounting position from the area between the insertion position and the final mating position, including the insertion position and the final mating position. In this case, the connecting element strikes against the connector housing before the two lever arms reach the mounting position from the area between the insertion position and the final mating position, including the insertion position and the final mating position. The two lever arms can therefore not be released from the connector housing in their joined condition. Unintentional loss of the lever arms or of the entire operating lever during operation is thus avoided.
  • the multipart operating lever may, when located at the stop, lockingly engage with the connector housing.
  • the connecting element may have e.g. a locking projection, which faces the connector housing.
  • the connector housing may have formed thereon a locking bump, with which the locking projection of the connecting element establishes a locking connection as soon as the stop is reached.
  • the lever arms of the multipart operating lever can thus be retained at the insertion position, so as to prevent unintentional pivoting of the operating lever during the mating process.
  • the two lever arms cannot be connected by the connecting element at their respective mounting position.
  • the connector housing is located between the freely projecting ends of the two lever arms, when the two lever arms are at their respective mounting position. In this way, it is ensured that the two lever arms can only be connected by the connecting element, when the two lever arms have been moved away from their respective mounting position.
  • each lever arm may have provided thereon a straight, web-like or rib-like handle, which extends on an outer side of the respective lever arm and has a characteristic orientation with respect to the connector housing, when the respective lever arm is at the mounting position.
  • the handle is oriented parallel to or perpendicular to an outer edge of the connector housing, when the respective lever arm is at the mounting position.
  • the pivot axis runs symmetrically through the handle. This simplifies both automated mounting and manual mounting of the respective lever arm, since the handle not only provides a contact area for a robotic gripping tool, but also constitutes a visual reference mark for manual mounting. In other words, the handle serves as a mounting aid for the respective lever arm.
  • each bearing hole may have a sealing face and a bearing face which are offset from each other in an axial direction of the bearing hole, with the inserted bearing journal resting on the sealing face and on the bearing face.
  • the sealing face and the bearing face are cylindrical and extend coaxially with respect to one another, the inserted bearing journal resting circumferentially on the sealing face and on the bearing face.
  • the bearing face may be configured such that it has at least a higher dimensional stability than the sealing face.
  • the bearing face may e.g. be the running surface of the hole bearing resulting from the bearing journal and the bearing hole and may be formed e.g. by the inner wall of the connector housing.
  • the sealing face may be formed e.g. by the at least one bearing seal. In this way, the inserted bearing journal is centered in the respective bearing hole by means of the bearing face so as to ensure the most uniform pressure distribution possible on the at least one bearing seal.
  • the underlying object defined at the beginning can also be achieved by an electrical connector with a housing assembly according to one of the preceding embodiments, wherein the connector housing has a mating face directed in a mating direction and surrounded by a circumferential seal. At least one electrically conductive contact element may be arranged in the mating face, the contact element being configured for contacting with a mating contact of the mating connector. Depending on the field of use of the electrical connector, a plurality of contact elements may optionally be arranged in the mating face. Due to the functionality and advantages of the housing assembly which have already been explained hereinbefore, and in particular due to the presence of the circumferential seal, also the electrical connector according to the present invention can advantageously be configured to save installation space and to be sealed.
  • the mating face may form a reception means for the mating connector.
  • the at least one bearing hole may lead into the reception means.
  • each bearing hole leads into the reception means. It follows that the bearing journal inserted into the respective bearing hole and in particular the at least one drive element can project into the reception means.
  • the at least one drive element may be located between the at least one bearing seal and the circumferential seal. This leads preferably to a compact arrangement of the at least one drive element.
  • the circumferential seal may be integrally connected to the at least one bearing seal, so as to avoid an undesired loss of the seals.
  • a sprue which is formed during two-component injection molding, may monolithically connect the circumferential seal to the at least one bearing seal.
  • the two bearing seals may be monolithically connected via a further sprue, which is also formed during two-component injection molding.
  • a fill channel extending between the two bearing holes may be provided at the connector housing. Further fill channels may lead from the respective two bearing holes to the mating face.
  • a connector assembly comprising an electrical connector according to one of the preceding embodiments and a mating connector that is configured to be intermateable with the electrical connector, wherein the mating connector is provided with at least one driven element that is arranged to be engageable with the at least one drive element of the operating lever, wherein the electrical connector and the mating connector form together a sealed interior, which is sealed, at least sectionwise, by the at least one bearing seal.
  • the interior of the connector assembly is sealed by the at least one bearing seal and the circumferential seal.
  • the connector assembly according to the present invention benefits from the advantages of the housing assembly and, thanks to the sealed interior, can be used in moist and/or dusty and/or dirty surroundings. Furthermore, the connector assembly according to the present invention saves installation space insofar as the at least one drive element of the operating lever cooperates directly with the at least one driven element of the mating plug. In this way, sliders or similar intermediate parts can be dispensed with. This reduces the installation space taken up by the connector assembly with its remaining components and also reduces the total number of components of the connector assembly.
  • the at least one driven element of the mating connector is e.g. a toothed rack formed on the mating connector. It follows that, when the at least one drive element of the operating lever and the at least one driven element of the mating connector are in engagement with each other, a pivoting movement of the operating lever will be converted via a rotary movement of the at least one drive element into a linear mating movement between the electrical connector and the mating connector.
  • a driven element is provided for each drive element of the operating lever.
  • the mating connector may have an end face located opposite the mating face of the electrical connector in a mating direction, the circumferential seal resting on the end face in the mated condition of the electrical connector and the mating connector.
  • the circumferential seal is pressed onto the end face in the course of the linear mating movement and will thus seal the mating face at least sectionwise.
  • the end face may here be formed by a plate encompassing the rest of the mating connector and extending perpendicular to the mating direction.
  • the at least one drive element of the operating lever may be in engagement with the at least one driven element of the mating connector in the sealed interior of the connector assembly.
  • each drive element of the operating lever is in engagement with the respective driven element of the mating connector in the sealed interior of the connector assembly. It follows that the drive and driven elements are located in surroundings protected against dust and dirt. This will reduce the wear of the drive and driven elements.
  • each bearing hole is preferably located in the sealed interior of the connector assembly. Accordingly, also the inserted bearing journal preferably rests on the bearing face in the sealed interior of the connector assembly.
