Definitions

  • the invention relates to an electric connector configured to be plugged to a mating electric connector.
  • CPA position assurances
  • the object of the present invention is to further improve the reliability and security of electric connections.
  • the electric connector mentioned above is improved by the invention in that the electric connector comprises a housing, at least one retaining member movable with respect to the housing between an open position and a retaining position and a position assurance assembly movable with respect to the housing between a pre-lock position and a locking position, wherein a movement of the position assurance assembly into the locking position is blocked by the housing if the electric connector is not plugged to the mating electric connector and by the at least one retaining member if the at least one retaining member is not in the retaining position.
  • the electric connector according to the invention has the advantage that the position assurance assembly can only be activated, e.g. moved or translated into the locking position if at least two conditions are met, namely a correct mechanical connection between the electric connector and the mating electric connector and a correct position of the retaining member.
  • Any number of retaining members is conceivable.
  • the number of retaining members corresponds to the number of conditions that can be checked or controlled with the position assurance assembly.
  • the retaining member can, in particular, be a second position assurance assembly that can only be activated, e.g. moved into the retaining position if an interior element, which position to be assured by the second position assurance assembly, is in its correct position.
  • 'correct position' is to be understood as a position of an element, respectively a relative position of two or more elements with respect to one another in which the entity that comprises said element or said elements is fully operational as intended.
  • the electric connector can be improved by further additional features that can be arbitrarily combined with one another. Further, individual features can be omitted if the technical effect of the omitted feature is not relevant to the present invention. Elements given in the singular or plural form can be present in plural or singular form in further embodiments.
  • This position assurance function has the advantage that an unintentional disconnection of the electric connector from the mating electric connector can be prevented.
  • a movement of the retaining member into the open position can be blocked by the position assurance assembly in the locking position.
  • the position assurance assembly thus secures a relative position of a housing of the electric connector and a housing of the mating electric connector one to another as well as a relative position of the retaining member with respect to the housing of the electric connector.
  • the housing of the mating electric connector can prevent the retainer from moving out of the retaining position.
  • This can be implemented by the mating electric connector at least partially surrounding the electric connector, in particular a portion of the electric connector that receives the retaining member. A movement of the retaining member out of the retaining position into the open position can be blocked by a wall of the mating electric connector. Accordingly, the retaining member being in the open position can prevent the electric connector from being pushed into the mating electric connector.
  • the retaining member can be configured to retain at least one sub-component of the electric connector, at least in the retaining position.
  • a sub-component can be one of an electric terminal, a circuit board, a plug insert, a sensor, a data or power transmission line, an indicator element or any kind of element that is required to be correctly positioned within the electric connector in order to guarantee its correct operability.
  • An electric connector that operates correctly does not show any malfunction or defects that result from incorrect positioning of any of its components.
  • the position assurance assembly can be movable along a first direction and the retaining member can be movable along a second direction, wherein the first direction can be oriented essentially perpendicular to the second direction.
  • a trajectory or travel path of the position assurance assembly can perpendicularly cross a trajectory or travel path of the retaining member.
  • the distinct directions along which the retaining member and the position assurance assembly can be moved, have the advantage of a clear indication if the retaining member is already in the correct position or not.
  • the position assurance assembly and the retaining member can therefore be provided at different side surfaces of the electric connector.
  • the different side surfaces can be oriented perpendicular to one another.
  • the position assurance assembly can be located underneath a latch.
  • the retaining member can protrude from a housing of the electric connector in its open position. In the retaining position, the retaining member cannot protrude from the housing of the electric connector, but can be entirely received within a cubature of the housing of the electric connector.
  • the electric connector can comprise a receiving opening configured to receive the retaining member that can be pushed into said receiving opening.
  • the electric connector can be improved in that the first direction can be oriented essentially parallel to a plug direction, along which the electric connector is plugged to the mating electric connector.
  • the position assurance assembly can have a U-shape.
  • the position assurance assembly can comprise two opposing legs connected to one another by an actuation base that can be configured to be operated by a user.
  • the U-shape can be advantageous in terms of mechanical stability, wherein both legs of the U-shape can be configured to support and/or guide the position assurance assembly within the electric connector housing.
  • the retaining member can also comprise a U-shape.
  • the position assurance assembly and the retaining member can overlap one another at least when the retaining member is in the retaining position and the position assurance assembly is in the locking position. In this positioning with respect to one another, one leg of the U-shape of the retaining member can be received between the two legs of the position assurance assembly and vice versa.
  • One of the two legs of the retaining member and/or the position assurance assembly can comprise elements having a first functionality being different from a second functionality of further elements that can be provided at the other of the two legs of the retaining member and/or the position assurance assembly.
  • the retaining member and/or the position assurance assembly can comprise at least one Poka-Yoke feature, e.g. a feature that prevents insertion or assembly of the retaining member and/or the position assurance member in an incorrect orientation to the housing of the electric connector.
  • the electric connector can be improved in that the position assurance assembly comprises a connector stop configured to block a movement of the position assurance assembly into the locking position if the electric connector is not plugged to the mating electric connector and a retainer stop configured to block a movement of the position assurance assembly into the locking position if the at least one retaining member is not in the retaining position.
  • the connector stop and the retainer stop can both provide a mechanical stop, thereby engaging a positive lock with the position assurance assembly.
  • the connector stop provides a positive lock between the position assurance assembly and the housing of the electric connector.
  • the connector stop can comprise an arbitrary form, such as a beak, a rectangular protrusion, a pin or simply a front surface of a preferably resiliently deflectable latch.
  • the retainer stop can comprise a stop surface facing in the first direction.
  • the retainer stop and the stop surface in particular can be configured to abut the retaining member, wherein said abutment is resolved once the retaining member is moved into the retaining position.
  • the connector stop and the retainer stop can be provided at two distinct longitudinal features of the position assurance assembly. This can be the case for a U-shaped position assurance assembly, wherein the connector stop and the retainer stop are provided preferably at the two opposing legs of the U-shape. This has the advantage of a clear spatial distinction between the two stops, while still allowing a common actuation of both of the stops upon actuation of the position assurance assembly.
  • the connector stop and the retainer stop can extend from the corresponding longitudinal features of the position assurance assembly, e.g. preferably the legs of the U-shaped position assurance assembly in opposite directions. These two opposite directions can be oriented essentially perpendicular to the first direction. Preferably, the opposite directions can further be oriented essentially perpendicular to the second direction along which the retaining member is actuated.
  • At least one longitudinal feature of the position assurance assembly can be deflectable towards the other longitudinal feature. It is particularly advantageous if the connector stop is provided at the resiliently deflectable leg of the U-shaped position assurance assembly.
  • a deflectable longitudinal feature of the position assurance assembly can be configured to be automatically deflected upon actuation of another element of the electric connector.
  • one longitudinal feature that comprises the connector stop can be automatically deflected towards the second longitudinal feature of the position assurance assembly when the electric connector is mated with the corresponding mating electric connector.
  • the deflection can be achieved by means of tilted surfaces or ramps that are oriented at an acute angle with respect to the first direction and that are configured to deflect said longitudinal feature.
  • the second longitudinal feature that comprises the retainer stop can be deflectable. Further, both longitudinal features can be deflectable towards one another.
  • the working principle of the connector stop and the retainer stop can be similar or can differ from one another.
  • the longitudinal feature comprising the connector stop is deflectable and the longitudinal feature comprising the retainer stop is not deflectable.
  • the positive fit between the connector stop and the housing of the electric connector can thus be disengaged by the mating electric connector pushing onto the longitudinal feature and thus deflecting it towards the second longitudinal feature.
  • the second longitudinal feature comprising the retainer stop can be received in the housing of the electric connector by or within guiding means that only allow for an actuation of the retaining member along or opposite the second direction.
  • Disengaging a positive lock between the retainer stop provided on the second longitudinal feature and a position assurance assembly stop (short: PAA stop) provided on the retaining member thus comprises linearly moving the PAA stop along the second direction out of the trajectory of the retainer stop that is oriented along the first direction.
  • the electric connector can be improved in that the position assurance assembly and/or the retaining member comprise at least one locking member configured to engage with a corresponding counter locking member of the housing for locking the position assurance member and/or the retaining member to the housing.
  • the locking member of the retaining member and/or position assurance assembly can secure each of those two elements in at least one of their positions, namely the retaining member in the open position and/or in the retaining position and the position assurance assembly in the pre-lock position and/or the locking position.
  • the locking member can comprise a locking beak, a locking recess, a resiliently deflectable locking element or a similar structure that prevents relocation of the retaining member and/or the position assurance assembly.
  • the locking can be overcome if a threshold force is exceeded that disengages said locking.
  • the retaining member can comprise an assurance assembly stop with a first stop surface and a second stop surface, wherein the first stop surface can be configured to block a movement of the position assurance assembly into the locking position and wherein the second stop surface can be configured to block a movement of the retaining member out of the retaining position.
  • the previously mentioned PAA stop can be referred to as an assurance assembly stop.
  • the assurance assembly stop has therefore the advantage of securing the retaining member in the retaining position.
  • first stop surface and the second stop surface can both be adapted to interact with the retainer stop, wherein the first stop surface and the second stop surface can face in two directions being essentially oriented perpendicular to one another.
  • the assurance assembly stop can therefore have two effects or functions.
  • the first stop surface can block a movement of the position assurance assembly into the locking position by abutting the retainer stop and engaging with said retainer stop in a positive fit.
  • said positive fit is disengaged and the first stop surface is no longer in mechanical contact with the retainer stop.
  • the position assurance assembly can now be moved to its locking position.
  • the electric connector needs to be fully plugged to the mating electric connector to allow actuation of the position assurance assembly.
  • the retainer stop is moved or translated along the second stop surface of the assurance assembly stop and, in the locking position of the position assurance assembly, the second stop surface prevents a movement of the retaining member out of the retaining position.
  • the invention further relates to a connector system, wherein any of the above-described examples of the electric connector can be provided in the connector system together with a mating electric connector.
  • the retaining member is adapted to block the insertion of the electric connector into a housing of the mating electric connector if the retaining member is not in the retaining position.
  • the position assurance assembly is movable along the first direction being perpendicular to the second direction, along which the retaining member can be moved.
  • the retaining member in the open position, can extend out of the housing of the electric connector. Said retaining member protruding from the housing can block insertion of the electric connector into the mating electric connector by physical abutment of the retaining member and a portion of a housing of the mating electric connector.
  • the retaining member is preferably located entirely within the electric connector.
  • the retaining member can also be within the electric mating connector when the connector system is fully assembled.
  • Fig. 1 shows an electric connector 1.
  • the electric connector 1 is an angled connector 3.
  • electric connector 1 can have a different shape, for instance the shape of a linear connector.
  • Electric connector 1 comprises a housing 5 that is formed by a first housing part 5a and a second housing part 5b.
  • housing 5 can be a single part.
  • First housing part 5a is a back cover 7 that is attached to second housing part 5b by latching means 9.
  • latching means 9 can be provided. Any number of latching means 9 can be provided in other embodiments.
  • Electric connector 1 comprises one retaining member 11 that is received movably in a retainer receptacle 13 of the housing 5.
  • the retaining member 11 is movable with respect to the housing 5 between an open position 15 (shown in Fig. 1 ) and a retaining position 17 (shown in Fig. 5 ) along or opposite to a second direction 19.
  • Electric connector 1 further comprises a position assurance assembly 21 that is movable with respect to the housing 5 between a pre-lock position 23 (shown in Fig. 1 ) and a locking position 25 (shown in Fig. 7 ).
  • Position assurance assembly 21 is abbreviated as PAA 21 in the following.
  • PAA 21 is movable along or opposite to a first direction 27.
  • Both, retaining member 11 and PAA 21 are partially received in housing 5.
  • Retaining member 11 is received in retainer receptacle 13 and PAA 21 is received in a PAA-receptacle 29.
  • PAA-receptacle 29 is best seen in Fig. 2 .
  • Housing 5 further comprises a first position assurance assembly latch member 31 (short: PAA latch member 31) and a second position assurance assembly latch member 33 (short: PAA latch member 33). Members 31, 33 are provided on a position assurance assembly latch 35 (short: PAA-latch 35) of housing 5.
  • the first PAA latch member 31 and the second PAA latch member 33 interact with a connector stop 37 as will be described in the following.
  • Electric connector 1 comprises a connector face 39 that is formed by the second housing part 5b and a connector insert 41.
  • Connector insert 41 shown in the figures is exemplary.
  • connector insert 41 can have a different shape (e.g. not rectangular) and comprise different keying features, keying recesses and receptacles (e.g. for electric terminals).
  • Fig. 2 shows electric connector 1 in a cut view.
  • PAA-receptacle 29 is formed below PAA-latch 35 of housing 5.
  • a movement of PAA 21 along first direction 27 being blocked by housing 5 is shown.
  • Connector stop 37 of electric connector 1 mechanically abuts second PAA latch member 33 and thus blocks a movement of PAA 21 into locking position 25 without electric connector 1 being plugged to a mating electric connector (not shown).
  • connector stop 37 the PAA-latch 35 as well as the first and second PAA latch members 31, 33 shown in the figures are exemplary. In other embodiments, different shapes are conceivable.
  • PAA 21 comprises a retainer stop 43 that is in mechanical contact with an assurance assembly stop 45 of retaining member 11.
  • retaining member 11 is also configured to block a movement of PAA 21 into locking position 25. This is the case as long as retaining member 11 is in the open position 15.
  • connector stop 37 and retainer stop 43 are provided at two distinct longitudinal features 47 of PAA 21, namely a first longitudinal feature 49 and a second longitudinal feature 51.
  • Connector stop 37 and retainer stop 43 extend in opposite directions from the corresponding longitudinal feature 47.
  • the first direction 27 is oriented essentially perpendicular to the second direction 19. Further, the first direction 27 is oriented essentially parallel to a plug direction 53, along which electric connector 1 can be plugged to a mating electric connector 55 (shown in subsequent Figs. 3 to 7 ).
  • Retaining member 11 is configured to retain at least one sub-component 57 of electric connector 1, at least in its retaining position 17 ( Fig. 5 ).
  • sub-component 57 can be the connector insert 41 that comprises a retaining recess 59. By receiving retaining member 11 in said retaining recess 59, a position of the connector insert 41 is secured.
  • retaining member 11 can only be moved along second direction 19 if connector insert 41 is correctly positioned inside housing 5.
  • different sub-components 57 can be retained by retaining member 11, for instance electric terminals or circuit boards.
  • PAA 21 comprises at least one locking member 61 in the form of a locking latch 63.
  • Said locking member 61 is configured to engage with a corresponding counter locking member 65 of the housing 5.
  • Counter locking member 65 is a locking protrusion 67.
  • second longitudinal feature 51 can comprise a locking protrusion 67 and housing 5 can comprise a locking recess (not shown). If PAA 21 is moved along first direction 27 (this is only possible under certain conditions that will be explained below), locking latch 63 can deflect towards first longitudinal feature 49 and can therefore be lifted above and (as seen along the first direction 27) beyond locking protrusion 67. Thus, PAA 21 can be locked to housing 5.
  • Locking position 25 of PAA 21 can be defined by said positive lock between locking latch 63 and locking protrusion 67.
