Definitions

  • the invention relates to a plug part for a circular connector with an insulating material housing, the insulating material housing having a plurality of receiving sleeves arranged next to one another for receiving one plug contact each and the plug part being pluggable onto a corresponding socket part in one plugging direction.
  • the invention also relates to a set of connector and socket part.
  • Plug connectors including round plug connectors, are used, for example, in electrical installations to connect electrical conductors to one another for line connection and signal transmission purposes, in order to mechanically connect the conductors to one another and to enable safe and reliable electrical contacting of the conductors.
  • plug connectors usually have a plug part and a socket part, which can be connected to one another.
  • Circular plug connectors are plug connectors with an essentially circular overall cross section on the plug surface, within which the electrical contacts are arranged.
  • the invention relates to plug parts which have an insulating material housing for the production of the mechanical plug connection and as protection against accidental contact, which housing has a plurality of receiving sleeves arranged next to one another, each for receiving one plug contact.
  • a receiving sleeve has an at least partially circumferential wall of insulating material, which delimits a plug-in receiving area for a plug-in contact, and enables defined plug-in guidance of the electrical contacts to be connected in conjunction with a protection against accidental contact.
  • the plug part can be plugged onto a corresponding socket part in a plugging direction, ie in particular can be plugged onto the socket part in a translatory manner with a plug surface of the plug part pointing to a plug-in surface of the socket part.
  • Under a corresponding socket part is one with the Plug part understood socket part compatible whose dimensions, geometric shape and surface fit together with a plug-in geometry of the plug part that the plug part and the socket part can be plugged into each other.
  • the plug-in surface is in particular the surface on which the plug part can be brought together with a corresponding plug-in surface of the socket part.
  • the free ends of the receiving sleeves can end on the plug-in surface.
  • the plug part and socket part can be plugged into one another in particular in such a way that their plug-in surfaces rest against one another and dip into one another with the respective plug-in components and associated plug-in receptacles.
  • the object of the invention is to provide a plug part for a circular connector of the type mentioned at the outset and a set made up of a plug connector and a socket part with improved protection against mismating.
  • the task is in accordance with a plug part for a circular connector
  • the plug part to have at least four coding devices, with the coding devices each being set up to prevent the plug part from being plugged in incorrectly.
  • a coding device is understood to mean one or more additional elements on the plug-in surface of the plug part, which, due to its geometric shape, requires a corresponding negative contour in the associated socket part in order to dip into this negative contour when the plug part and socket part are connected to the additional element can.
  • the coding device usually does not have to fulfill any electrical contacting function, although this is not ruled out in principle.
  • the plug-in connection is made possible by the coding device only in a defined orientation of the plug part and socket part and with a suitable compatibility of the plug part and socket part with one another. In particular, incorrect insertion due to a mechanical blocking of the connection process by the coding device is absolutely prevented.
  • the coding device can be configured as a projection-like additional element that protrudes beyond the plane of the plug-in surface in the plug-in direction, and the socket part can have a corresponding recess or indentation in the corresponding position, or vice versa.
  • a coding device designates a specific geometric type or group of additional elements that can each be viewed individually as a coding unit.
  • Several coding units of the same basic geometric shape can form a coding device.
  • the connector part can thus have a certain number of coding devices and the same or a higher number of coding units.
  • the coding devices can be, for example, webs, pegs, pins, collars, frames or other geometric shape elements.
  • multi-pole plug connectors for example two-, three-, four- or five-pole plug connectors, several coding units of a coding device can be provided.
  • a number of at least four coding devices enables particularly reliable protection against mismating.
  • the comprehensive coding makes it easier to avoid mismating, for example over an edge area or at an angle to the mating surface, and the mismating protection can no longer be circumvented.
  • a one-to-one compatibility of the plug part with a corresponding socket part is made possible, so that incorrect insertion with an incompatible socket part can be reliably ruled out. Due to a highly individual "plug face" on the plug surfaces of the plug connection, the plug part can only be connected to associated socket parts and in only one possible orientation to one another.
  • the coding provided also reliably prevents plug parts and socket parts with different numbers of poles from being connected to one another.
  • the receiving sleeves arranged next to one another can span a contact plane in the insertion direction, with at least one of the coding devices being arranged above and/or below the contact plane.
  • the part of the surface of the plug-in surface that is frequently unused, particularly in the case of circular plug-in connectors above and below the contact level can be used for a coding device.
  • the coding devices can be arranged between the receiving sleeves. As a result, the coding device can support the defined guiding of the plug part and socket part into one another.
  • the coding device is designed as a coding chamber with at least partially surrounding walls.
  • the coding chamber can, for example, be a section on the plug-in surface that is delimited on the sides by walls of insulating material. It is conceivable that two sides, three sides, four sides or more sides form the section delimited by walls of insulating material.
  • a coding chamber With a coding chamber, a comparatively large coding device is provided, which can enable the plug part and socket part to be brought together more easily or centered relative to one another.
  • the coding device is arranged between the receiving sleeves on the contact plane. In this way, too, improved guidance or centering can be provided.
  • At least one of the coding devices can be designed as a coding bar, with the coding bar protruding from the receiving sleeves.
  • the coding bar can, for example be integrally formed with a receiving sleeve.
  • a coding bar can, for example, have an elongated, narrow bar shape and extend with its main direction of extension parallel to the plug-in surface. Due to their narrow shape, coding bars can be arranged on a plug-in surface in a very space-saving manner.
  • a plurality of coding ridges protrudes from the receiving sleeves, with at least two of the coding ridges having different lengths. This means that one coding bar can be longer or shorter than another coding bar.
  • the number of coding options and the coding clarity can be increased in a simple manner due to the large number of coding bars and different coding bar lengths.
  • the plurality of coding webs can protrude from the receiving sleeves both in an area above the contact plane and in an area below the contact plane. This also allows the number of coding options and the coding clarity to be increased.
  • At least one of the coding devices can be protruded from the plug part in the plug-in direction.
  • the coding devices can have the same height as the receiving sleeves, that is to say they cannot protrude beyond the receiving sleeves in a profile of the plug part viewed from the side.
  • One or more coding devices can also have a smaller or larger height than the receiving sleeves.
  • the coding devices can have different heights, that is to say they can end at different height levels as seen in the plug-in direction.
  • At least one of the coding devices is arranged above and/or below the contact plane spanned by the receiving sleeves arranged next to one another, it can be advantageous if at least one coding device is used as a coding profile arranged above and/or below the contact plane is made of wall pieces made of insulating material.
  • a coding profile can be provided as a separate or additionally installed coding device made of insulating material, which is not directly or integrally connected to the receiving sleeves, for example.
  • the coding profile can have any geometric shape.
  • the coding profile can, for example, be designed in the shape of a partial circle, at least in sections.
  • sections can mean here that a partial contour of the coding profile is formed in the shape of a part of a circle.
  • the coding profile can thus have a round contour in sections or be designed as a round, circumferential collar.
  • the part-circular contour can run parallel to the circumference of the circular outer contour of a circular connector.
  • the other contours of the coding profile which is partially circular at least in sections, can run parallel to other contours, for example parallel to contours of the receiving sleeves or to contours of other coding devices such as the coding webs.
  • the coding profile can have sections that run at least partially in a straight line and/or the coding profile can be formed from angled straight lines, ie at least two straight lines that form at least one angle.
  • arcuate or at least partially arcuate coding profiles are also conceivable. In principle, it is possible for the geometric shapes to be combined in order to provide the entire geometric shape of a coding profile.
  • the coding profile can extend parallel to the contact plane, at least in sections.
  • sections can mean that a partial contour of the coding profile runs parallel to the contact plane.
  • the contour of the coding profile also runs parallel to the contact plane over its entire geometric dimension.
  • the circumference of the plug part can be formed by an at least partially circumferential housing contour, with the receiving sleeves being arranged within the housing contour.
  • the housing contour can form an outer contact protection and a guide contour that simplifies the connection of the plug part to a corresponding socket part.
  • the housing contour can have a smaller, larger or the same height as the receiving sleeves.
  • the housing contour can be made of an insulating material.
  • At least one of the coding devices runs parallel to the housing contour, at least in sections.

  • At least one of the coding devices is arranged above and/or below the contact level spanned by the adjacent receiving sleeves, it can be advantageous if at least one further receiving sleeve for receiving a further plug contact is arranged above and/or below the contact level.
  • the space available above and/or below the contact level can be used not only for coding devices, but also for additional plug contacts.
  • the further receiving sleeve can form a coding device due to its offset position in relation to the contact plane.
  • the invention is particularly suitable for round plug connectors because, compared to square plug connectors, there is often more surface area available on the mating surface due to the circular cross section, which makes it considerably easier to arrange at least four coding devices.
  • the risk of mismating is significantly higher with circular connectors than with angularly shaped connectors, since with regard to the external geometry of circular connectors in the plane of the plug surface, all rotations of the plug part and the socket part are possible in the range of 360°, while, for example, with rectangular or square shaped connectors the external geometry already allows only two or four plug-in orientations of the plug part and socket part towards one another.
