  • the present invention relates to a plug connector system comprising a socket housing and a pin housing in order to establish an electrical connection between one or several electric wires.
  • Plug connector systems as mentioned above are generally used, on the one hand, for providing a detachable connection at certain system specific interfaces in lines for routing signals and/or in lines for transmitting higher electrical powers and, on the other hand, for, nevertheless, ensuring a permanent and reliable contact between the portions connected by the plug connector system.
  • a wide variety of plug connector systems is available, typically tailored to respective requirements. In this respect, it is not only mandatory to ensure reliable electrical connection, but there is also a need to provide appropriate measures in order to prevent unintentional detachment of the plug connection, while still enabling a reliable decoupling of the socket housing from the pin housing.
  • plug connector systems are used in many technical fields due to the ongoing integration of more and more electronic devices into an entire system, wherein, in addition to adapted installation size and shape as well as reliable contact, robustness with respect to sophisticated environmental conditions may also have to be provided.
  • One example in this respect is the field of the automation, since here, particularly sophisticated constraints are encountered, such as high mechanical load due to vibrations and the like, large temperature differences, very different air humidity, and the like, while, on the other hand, a high degree of accessibility and operability at the lowest possible weight and reduced installation size are required, since in this technical field, maintenance, measurements and the like may have to be frequently performed, thereby possibly requiring connector detachment and reconnection.
  • respective battery management systems are typically provided for monitoring individual cell modules, so that independent of the number of cell modules used, a corresponding high number of control lines, signal lines and power conducting lines are present.
  • the lines provided for monitoring tasks are detachably connected to the management system so as to simplify on the one hand, the installation of the battery system and, independent thereof, the installation of the control system and, on the other hand, to enable a high degree of accessibility, wherein the modularity of the battery system is also typically desired and may be taken advantage of in order to replace individual modules.
  • plug connector systems that, in particular, may be used in such sophisticated applications and which may, in particular, meet the above-identified requirements. It appears, however, that currently available plug connector systems may not meet the full requirements with respect to desired performance in terms of flexibility during the application, with respect to simplifying the handling of the plug connector system and with respect to requirements concerning installation size, in combination with the required reliability.
  • US2010136819A1 discloses a connector which is provided with a pair of female and male housings connectable with each other.
  • the female housing includes a block-shaped housing main body and the male housing includes a receptacle having an inner surface shape conforming to outer surfaces of the housing main body. Corners on the outer surface of the housing main body diagonal to each other are bevels with different shapes.
  • the bevels include moderately inclined portions located at the opposite ends of the upper surface of the housing main body and inclined at a relatively large angle with respect to a height direction and steeply inclined portions located at the opposite ends of the lower surface of the housing main body and inclined at a relatively small angle with respect to the height direction.

  • the terminals position assurance insert is inserted into the housing from the rear and abuts a projection on each terminal thus assuring that the resilient housing latch engages the terminal.
  • a connector position assurance insert attached to the terminal position by a integral strap is inserted beneath a connector latch to prevent the depression of the latch. A strap is deformed so that the connector position assurance insert is located parallel to and adjacent to the terminal position assurance insert when the two are fully seated in the connector.
  • the terminal position assurance insert is inserted immediately adjacent a side wall of the connector housing on which the connector latch is mounted and above a wire crimp and insulation barrel portion to the rear of the projecting section of the terminal.
  • Both the terminal position assurance insert and the connector position assurance insert include laterally deflectable latching springs for retention in the housing.
  • US5641300 A discloses an electrical connector for wiring harnesses and other electrical devices, which has a lock member to hold the connector in engagement with a mating connector and a latch to guard against inadvertent release of the lock member.
  • the latch is connected by means of a living hinge to a terminal retainer holding a plurality of terminals within the connector and is movable by a worker between a latched position inhibiting movement of the lock member to an unlocked condition and an unlatched position offering no obstruction to movement of the lock member.
  • the latch When in the latched position the latch also serves to prevent wires or other foreign objects from becoming entangled with the lock member during shipping and handling.
  • US5947763 A relates to an electrical connector system having first and second mateable housings and a connector position assurance member for bi-directional sliding movement on the second connector housing.
  • the first connector housing includes a primary lock ramp thereon and the second connector housing has a primary lock constructed and arranged for pivotal movement and for locking against the primary lock ramp when the first and second connector housings are fully mated.
  • the connector position assurance member is slidable on the second connector housing in a direction co-linear with the mating direction of the connector housings to a pre-staged position and so that the primary lock is uninhibited from pivotal movement.
  • the connector position assurance member includes a first lock mechanism that temporarily locks the connector position assurance member from slidable movement on the second connector housing in a direction perpendicular to the mating direction of the connector housings when the connector position assurance member is in the pre-staged position.
  • the first lock mechanism can be disengaged and unlocked when the first and second connector housings are fully mated allowing the connector position assurance member to be slid in a perpendicular direction to a final fully seated position. In the final fully seated position, the connector position assurance member blocks the primary lock from pivotal movement preventing the primary lock from being disengaged from the primary lock ramp.
  • US6203364 B1 discloses an electrical connector assembly having mateable male and female connector members includes a separate slide clip component that is received in a channel of the male connector and is provided with attachment features for mounting the assembly to support structure.

  • the connectors are only partly interconnected, upon initially insertion of the connector position assurance and assist device through the connector with the extended lock arm means it will assist the two connectors to become fully and rigidly mated, whereas if the device is initially inserted via the connector with the sized window it will refuse the further mating of the connectors and actually effect their separation whereby to prevent any type of connector partial engagement or intermittent electrical connection to occur.
  • a plug connector system as defined in claim 1 that comprises a pin housing and a socket housing.
  • the pin housing has a contact assembly including one or more pin contacts.
  • the socket housing comprises a contact assembly formed in a complementary manner with respect to the pin assembly and comprises a locking element that is attachable to the pin housing for locking the pin housing and the socket housing.

  • This combination of both functions required for a reliable plug connector system in total results in reduced installation size and an improved degree of operability. Thereby, both functions may be "activated” or "deactivated” by moving the assurance in the transverse direction.
  • the pin housing comprises a recess extending transverse to the plug direction, with a projection of the assurance complementarily formed thereto being engaged therewith, wherein the projection is movable in the recess. That is, the projection that ensures mechanical contact with the contact pins is a structural component which may be produced in a simple and highly reproducible manner without requiring additional measures to implement the secondary assurance of the contact pins. That is, in advantageous embodiments, the projection is in mechanical contact with any of the contact pins of the pin housing at the locking position, thereby securing the contact pins.

  • the resilient prefixing element is capable, due to its elasticity, of allowing a certain amount of tolerance without, however, impairing the basic positioning and fixing. In this manner, a high degree of operability during the installation and connection of the inventive plug connector system is accomplished, in particular, during installation and connection of the socket housing.
  • one or more fixing elements are provided that are configured for final fixation of the socket housing. That is, following the mounting of the socket housing at the location and position determined by the prefixing element, thereby obtaining the desired clearance, the actual final fixing may be accomplished by the one or more fixing elements, for instance, in cooperation with complementary elements at the installation location, in a connector plate and the like.

  • the pin housing and/or the socket housing comprises a resilient prefixing element configured for fixation with a tolerance given by the elasticity of the prefixing element. That is, in this aspect, the above-described positioning of the socket housing or the pin housing may be performed on the basis of a degree of elasticity determined by constructive measures, thereby enabling an adaptation to the target application, as is also explained above.
  • the prefixing element may be provided in the form of a modular functional block that is coupled on demand to the remaining part of the pin housing or the remaining part of the socket housing.
  • one or more fixing elements are provided in addition to the elastic prefixing element with the one or more fixing elements being configured for final fixation.

  • an assurance is provided that is movable between a locking position and an unlocking position for locking the pin housing and the socket housing with the assurance, providing a secondary assurance of the pin assembly and/or the contact assembly in the locking position. That is, in this example, an advantageous effect is achieved with respect to mounting, space requirements, and the like, of the plug connector system of the present invention in that the assurance has a double function. That is, by a simple movement of the assurance, it is possible to obtain a locking state and, on the other hand, a secondary assurance may be provided.
  • the pin housing may be configured such that a mechanical contact to any contact pins may be achieved in the locking position, or the socket housing may be configured such that a mechanical contact is obtained to any contact elements, if considered advantageous.
  • the assurance may be configured such that a secondary assurance of contact pins and contact elements may be concurrently obtained, if considered appropriate.
  • moving between the locking position and the unlocking position is accomplished by a transverse movement with respect to a plug direction. This results in a superior degree of flexibility and also leads to the possibility of reducing the size of the mounting location and/or the plug connector system.
