Definitions

  • connection assembly here designates an assembly comprising a first connector and a second connector which must be fixed to each other. These connectors are normally provided for connecting together cables or at least communication circuits, in order to allow the exchange of information between first circuits linked to the first connector and second circuits linked to the second connector.
  • connection assemblies which must be miniaturized, the space available for connecting and disconnecting the connectors being very small. It therefore concerns in particular the connection assemblies provided to comply with the MIL-DTL-32139 standard (format usually called 'nano-D').
  • connection assemblies of known type comprise a first connector and a second connector, which are fixed to each other in the fixing position by means of screws.
  • the screws ensure a reliable and proven fixing; however, the connection and disconnection operations are long, a tightening operation to a predetermined torque being necessary, and can be difficult if there is only very little space available for screwing and unscrewing the screws.
  • connection assemblies whose connectors are fixed to each other in the fixing position by means of fixing hooks. These hooks are attached to the second connector using counterbores, machined on the sides of the latter.
  • This method of fixing has satisfactory reliability; however, the use of square brackets can cause problems if the space available for connection and disconnection operations is very small.
  • the documents US 2013/034986 A1 and NL 1022227 C2 disclose connection assemblies according to the preamble of claim 1.
  • connection assemblies capable of ensuring a connection in a reliable manner, but whose connectors can be connected and disconnected simply and quickly, and in a very small volume.
  • this connection assembly comprises a first connector and a second connector.
  • the first connector includes a post having an axis.
  • a body of the second connector comprises a fixing passage for the column, and is arranged to allow the column to enter said fixing passage by moving forwards in a fixing direction, until reaching a fixing position .
  • the first connector and the second connector are configured such that in the fixing position, the column is prevented by a stop device from moving in a direction of disassembly, which is a direction opposite to the direction of fixing.
  • the first connector and the second connector are configured such that an external action applied only to the column allows the column to pass from the fixing position to a released position, in which the column is disengaged from the abutment device and can move in translation in the direction of disassembly.
  • the column In the fixing position, the column is in a predetermined angular range.
  • the connection assembly further comprises angular return means, comprising for example a spring, configured to return the column in said predetermined angular range relative to the axis of the column, when the column is fixed to a body of the first connector before it is attached to the second connector.
  • the term 'column' designates any part (or set of parts) consisting mainly of an elongated part capable of being placed in a bore of corresponding shape.
  • 'direction' means a direction as defined by a straight line or a set of parallel straight lines.
  • a direction can possibly have a meaning, that is to say be oriented, depending on the context.
  • the post in the fixing position, passes through a guide passage arranged in a body of the first connector, and its end is placed in the fixing passage of the second body. Consequently, in the fixing position, the column ensures alignment of the body of the first connector relative to the body of the second connector. However, more generally the alignment of the body of the first connector with the body of the second connector can be ensured by any means.
  • connection assembly presented above can naturally comprise more than one post for fixing the two connectors to each other.
  • Each column can have all or part of the characteristics and operation indicated for the column presented here.
  • one or more of the pins may be only axial guide pins, provided to contribute to maintaining the alignment of the first connector with the second connector in the fixing position, but which have no function of maintaining in position axial of the first connector vis-à-vis the second connector.
  • connection assembly is preferably configured so that the connection of the column is done automatically when the positioning of the column (by a movement in translation) in the fixing passage. This means that, during this movement, the abutment device preventing the column from moving in the opposite direction, following the dismantling direction, is put in place without external action and performs its retaining function.
  • connection assembly can have all or part of the following additional characteristics:
  • the external action comprises (and advantageously may comprise only) the application of a torque, allowing when the pin is in the fixing position to rotate it around its axis, and thus to move it from an angular position of attachment to a released angular position different from the angular position of attachment.
  • the column In this released angular position, the column is in the released position.
  • the column may or may not occupy the same axial position, in the fixing position and in the released position.
  • one end of the column has a circumferential surface; in a first angular sector, the circumferential surface has a recessed surface delimited at the front in the fixing direction by a first shoulder, the recessed surface being located radially set back with respect to the first shoulder; the abutment device comprises a retaining tongue secured axially to the second connector; and the first and the second connector are configured such that when the column is in the fixing position, the retaining tab is disposed radially in front of the recessed surface, and is held in front of the first shoulder, in a view along the direction of attachment.
  • connection assembly can thus comprise holding means configured to, when the column is in the fixing position, hold the retaining tab opposite the first shoulder in the direction of fixing (that is to say that, in seen along the direction of attachment, the first shoulder is aligned with the retaining tab; while also being located axially in front of the latter).
  • the further recessed surface is delimited at the rear along the fixing direction by a second shoulder.
  • the recessed surface is located radially recessed relative to the second shoulder.
  • the external action in this embodiment, can then comprise an axial thrust which moves the pin in the fixing direction.
  • the first and the second connector are configured such that, when under the effect of this axial thrust, the column moves in the fixing direction, the second shoulder moves until it is axially at the level of the retaining tab , pushing the retaining tab radially outwards.
  • the circumferential surface in a second angular sector, has a disassembly surface, having no shoulder in the fixing direction; and the first and second connectors are configured such that when the post is in the released position, the retaining tab is disposed radially (i.e., in view in a radial direction) in front of the surface of disassembly.
  • the retaining tab, or retaining claw is a part or set of parts of any shape.
  • the second connector may optionally comprise not a single tab, but a plurality of retaining tabs, each having all or part of the characteristics indicated above.
  • connection assembly comprises tab return means, in particular elastic return means, configured to, in the absence of the post, hold the retaining tab in the fixing passage , at the same radial position as the shoulder of the column (in view along the fixing direction).
  • tab return means in particular elastic return means, configured to, in the absence of the post, hold the retaining tab in the fixing passage , at the same radial position as the shoulder of the column (in view along the fixing direction).
  • connection assembly is preferably configured so that the connection of the column is done simply by moving the column (in translation) in the fixing passage. During this movement, the retaining tongue itself comes into engagement against the shoulder of the column, thus ensuring the axial fixing of the latter.
  • connection assembly is configured in such a way as to allow movement of the column from a disassembled position in which the column is at a distance from the second connector, to the fixing position.
  • the retaining tab (which is therefore, in the absence of the pin, disposed in the fixing passage due to the tab return means) is pushed radially outwards by the shoulder when fitting the baluster in the attachment passage, then resets radially inward opposite the recessed surface when the shoulder has moved forward past the retaining tab.
  • the tab return means consist of the retaining piece, the retaining tab being integrally formed with the retainer.
  • the first connector comprises an angular abutment
  • the column comprises an angular abutment, said angular abutments being configured to come into contact when the angular return means return the column in said predetermined angular range .
  • the column is then placed in the angular fixing position, that is to say the angular position which allows that, when connecting the first connector to the second connector, the recessed surface comes to be placed directly radially opposite the tab restraint.
  • the angular return means may for example comprise a torsion spring, for example helical.
  • the first and the second connector are configured so that the post can pass from the released position to a disengaged position, in which the post is placed further back than in the fixing position, and in which the second connector allows the post to come out of its fixing passage, whatever the angular position of the post.
  • the first connector comprises axial return means such as a spring configured, when the column is in the released position, to move the column in the dismantling direction to a position disengaged in which the post relative to a body of the first connector, is placed behind its axial position in the fixing position, and in which the second connector allows the post to come out of its fixing passage, whatever the angular position of the column.
  • axial return means such as a spring configured, when the column is in the released position, to move the column in the dismantling direction to a position disengaged in which the post relative to a body of the first connector, is placed behind its axial position in the fixing position, and in which the second connector allows the post to come out of its fixing passage, whatever the angular position of the column.
  • said angular return means and said axial return means consist mainly of the same helical spring, configured to act in torsion and in compression.
  • This spring can in particular be arranged around the column.
  • the first connector comprises an axial stop device, making it possible to limit an axial displacement of the column in the dismantling direction with respect to the first body when the column is fixed to a body of the first connector before it is attached to the second connector.
  • the axial stop device comprises a stop ring arranged around the column, and a shoulder formed on an inner surface of the guide passage, the stop ring coming into abutment against the shoulder when the column moves in the dismantling direction.
  • the stop ring can for example be a split ring, arranged in a circumferential groove of the column.
  • connection assembly comprises spacer means configured to elastically space the first connector relative to the second connector in the fixing direction, when the first connector and the second connector are connected to one another. These spacer means make it possible to position the retaining tab in abutment against the first shoulder when the pin is in the fixing position.
  • spacer means may in particular comprise at least one spacer blade, able to be placed between the first connector and the second connector.
  • the external action comprises an axial thrust moving the column in the fixing direction.
  • the column can operate in particular according to the 'push-latch' principle: to disconnect the column from the second connector, it is first necessary to push it slightly in the fixing direction, to release it from the second connector; it is then possible to disengage it from the second connector, as well as the whole of the first connector, by moving it in translation in the direction of disassembly (that is to say, the direction opposite to the direction of attachment).
  • the column passes from the fixing position to the released position simply by an action on the column itself.
  • This column passing through the second connector, this action can be done substantially along the axis of the column, and not on the sides of the connectors. Thanks to this, the disconnection of the column can be done in a reduced volume.
  • connection assembly 1 constituting an example of a first embodiment of the present disclosure will now be presented in relation to the figures 1 to 14 .
  • the connection assembly 1 comprises a first connector 100 and a second connector 200. These connectors are configured to allow the connection of conductors designed for the communication of telecommunication signals or for transmitting electric current.
  • Each of the connectors 100 and 200 can be fixed to a fixed support, in particular an electronic card such as a PCB, and/or be fixed to a telecommunications cable comprising a certain number of conductors allowing the transport of electrical signals and/or current(s).
  • the connector 100 is configured to be connected to the connector 200 by simply causing it to move along a direction of fixing X+ (the direction of dismantling X- being the opposite direction), until it reaches a final position, called position fixing (the connector 200 remaining fixed).
  • the directed side of the side indicated by the fixing direction X+ is called 'front side', while the opposite side is called 'rear side'.
  • the connector 100 comprises a body 110 and two columns 120 (the connector 100 could comprise only one column, or it could comprise 3, 4, 5 or more). Although the posts can be formed integrally with the body 110, in this embodiment they are separate parts thereof.
  • a post 120 has a head 122 and a stem 124, which are both substantially cylindrical and coaxial.
  • the post is fixed to the body 110 of the first connector 100 by passing the post 120 through a guide passage 112 provided in the body 110.
  • the post 120 is configured to be able to be introduced into the corresponding passage 112 along the fixing direction X+. It cannot, however, exceed a position of maximum displacement, because the head 122 cannot enter the passage 112 in its central section 114, which is of smaller diameter than that of the head 122.
  • a stop ring 130 is then fixed on the column 120, by clipping the latter (made for this purpose in a suitable elastic material) in a circumferential groove 128 of the column.
  • the ring 130 which is a split ring, is introduced on the column from the front end 125 thereof.
  • the guide passage 112 includes a circumferential stop 116 at the level of which, in the dismantling direction, its inside diameter changes from a value slightly greater than the outside diameter of the ring 130 to a value less than this diameter.
  • the stop 116 prevents the movement of the pin 120 in the direction of dismantling beyond a certain position, in which the stop ring 130 is in abutment against the stop 116.
  • Connector 200 includes a body 210 and a retainer 220.
  • the retainer 220 has a retainer tab 222.
  • a fixing passage 212 is formed for each post 120.
  • Each fixing passage 212 of the body 210 is arranged so as to be able to be placed opposite a guide passage 112 of the body 110, and has a diameter interior substantially equal (to the nearest clearance) to the outside diameter of the rod 124. Consequently, when the pin 120 is in the fixing position, and a front part of the pin 120 is engaged in the fixing passage 212, the passages guide 112 and fixing 212 are kept coaxial and facing each other by the column.
  • Recessed surface 136 between first and second shoulders 138 and 139, forms a notch 137 in circumferential surface 132.
  • the dismantling surface 134 in this embodiment, is a surface having a transverse section (in a plane perpendicular to the axis X) that is substantially constant regardless of the position along the fixing direction X+, from the axial position of the tab 222 (in the fixing position of the column) to the tip of the column.
  • this transverse section forms an arc of a circle of radius R centered on the X axis.
  • the dismantling surface 134 has no shoulder, no protrusion liable to prevent the tongue 222 from moving as far as the tip. of the column 120 by sliding on the surface 134.
  • the recessed surface 136 which is delimited at the front by the first shoulder 138, is located radially set back with respect to this shoulder, that is to say it is arranged radially in a range of distances d from the axis X less than the radius R of the shoulder 138.
  • the shoulder 138 has a cylindrical shape with the same radius R as the dismantling surface 134. Consequently, the recessed surface 136 forms a recessed surface not only with respect to the shoulder 138 but also by relative to the dismantling surface 134.
  • the second connector is further equipped with retainer 220.
  • retainer 220 may be integrally formed with body 210 (as shown in Fig.17 ), in the proposed embodiment it is a separate part, rigidly fixed to the body 210.
  • the part 220 is a part formed from a part of folded and cut metal strip, and which has a wide range of elastic deformation.
  • the body 210 and the part 220 are configured in such a way as to allow the part 220 to be rigidly fixed to the body 210. This fixing can be ensured by any suitable means.
  • the tongue 222 of the part 220 is inclined with respect to the direction of attachment, so that it is all the closer to the axis X as one moves forwards along the direction of attachment X+ .
  • the tongue 222 is arranged opposite the fixing surface 136.
  • the end of the tongue then bears both on this surface 136, and on shoulder 138.
  • the retaining tongue 222 in this position, is maintained at the same radial position (is at the same distance from the axis X) as the shoulder 138, and thus prevents the output of the pin 120 from the passage 212.
  • the first connector 100 is further equipped with a spring 140.
  • This spring 140 is a spring acting both in torsion and in compression, and is an example of angular return means and axial return means within the meaning of the present disclosure.
  • the spring 140 is configured to, when the column 120 is mounted in the passages 112 and 212, rotate the column 120 around its axis and thus return it to a certain position or at least an angular range. This action serves to place the pin 120 in the angular position known as the 'angular fixing position', in which, if the pin 120 is engaged in the passages 112 and 212, the tongue 222 will come to rest on the recessed surface 136: it is the angular position represented in particular on the Fig.3 and 4 . As will be explained later, the column 120 is placed in the angular fixing position not only thanks to the spring 140, but thanks to the action of the spring 140 combined with the presence of angular stops 142 and 144.
  • Fig.5 represents an angular position called 'released angular position' (or 'angular dismantling position'), in which the tongue 222 is not resting on the fixing surface 136, but on the contrary is resting on the dismantling surface 134.
  • the column When connecting the first connector 100 to the second connector 200, the column is engaged in the passages 112 and 212. During this movement, to allow the tongue 222 to be put in place against the recessed surface 136, column is in an angular position (the angular fixing position) which corresponds to the angular position of the retaining tab.
  • the body 110 comprises a stop 142, and the head 122 of the column comprises a corresponding stop 144. These stops are configured so as to block in rotation (relative to the axis of the guide passage) the column 120 in the desired angular position.
  • the body 110 and the head 122 of the column also comprise stops 146,148 which prevent the column from being rotated by an excessive angle in the opposite direction of rotation.
  • the column head 122 has a hexagonal bore 150 thanks to which it can be rotated using an Allen key (any other shape of head making it possible to drive the column in rotation about its axis would of course be possible).
  • the spring 140 acts not only in torsion to maintain the column 120 in the angular position desired for its attachment, but also in compression.
  • the standoff head is axially at the end of the body 110, and does not protrude from the body. 110 in the direction of disassembly (that is to say, does not extend on the side of the direction of disassembly beyond the end plane P of the body 110).
  • the spring 140 holds the column in the “ready to connect” position, since it then holds each of the columns in the angular fixing position.
  • This "ready to connect” position allows a quick and secure locking of the connection, and in some cases blind.
  • the end of the columns is conical to ensure the pre-guiding of the columns.
  • the retainer plays a role of placing the first connector 100 in a predetermined relative position with respect to the second connector 200.
  • the connectors 100 and 200 are configured such that in the fixing position, these slats are sandwiched between the facing walls of the body 110 and the body 210. Consequently, due to their elasticity, the slats tend to separate from each other, in the direction of assembly, the two bodies 110.210.
  • each post 120 is placed in one of the passages 112 of the body 110 of the first connector and equipped with its stop ring 130.
  • the connector 100 is positioned opposite the connector 200 so that the axes of the columns 120 coincide with the axes of the fixing passages 212 in which they must be placed. (As before, the following description refers to a single column 120, but the comments made for this column are applicable to all the columns).
  • the connector 100 is approached to the connector 200 by moving it along the fixing direction X+.
  • the column 120 is placed automatically in the angular fixing position, thanks to the return torque of the spring 140 and the angular stops 142.144.
  • the end 125 of the column engages in the fixing passage 212.
  • the tongue 222 which is at this stage ( Fig.6 ) by elasticity recalled in position in the fixing passage opposite the column 120 (along the axis X) is pushed radially outwards by the end 125 of the column, which allows the column to continue its movement forward ( Fig.7 ).
  • the first connector is then stopped moving forwards. At this time, the column heads 122 still protrude from the rear of the box 110.
  • the elastic strips 224 are at this time in compression between the two connectors 100 and 200, and tend to separate the body 110 from the body 210. Under the effect of this pressure, the column 120 is biased rearwards, which maintains the end of the tongue 222 resting firmly against the shoulder 138.
  • the connectors are initially in the fixing position ( Fig.8 ).
  • the column 120 is rotated around its X axis using an Allen key ( Figs.9,10 ). During this movement, the column moves from the angular fixing position ( Fig.4 ) to the released angular position ( Fig.5 ). The end of the tongue 222 is gradually pushed back radially by the recessed surface 136 and comes into contact with the disassembly surface 134. In the latter position, the column 120 is no longer prevented from moving in the dismantling direction by the shoulder 138, and the first connector 100 can be moved rearward.
  • means for locking the column in rotation, once it has been placed in the released angular position may be provided.
  • the disassembly surface 134 and the retaining tab can be configured such that, once the pillar is placed in the released position (and can then move in the direction of disassembly), the pillar is required to remain in a fixed angular position with respect to its axis.
  • This locking in rotation which must not prevent the column from sliding relative to the second connector, can be achieved in particular thanks to a form of cooperation between the retaining tab and the dismantling surface.
  • the disassembly surface may include a guide groove such as the groove 135 shown on the Fig. 16 .
  • the embodiment shown in this figure is identical to the first embodiment, except that the guide groove 135 is provided in the disassembly surface 134.
  • step S120 When disconnecting the connector 100, in step S120) the column 120 is rotated around its axis.
  • the tongue 222 is found (radially) in front of the dismantling surface 134. Consequently, the tongue 222 is placed at the bottom of the groove 135, and therefore prevents the column 120 from rotating around its axis, and this despite the return torque exerted by the spring 140. It follows that during step S130, the pin can be extracted from the passage 212 without risk that the tongue 222 does not come to interrupt this movement by locking against the first shoulder 138 .
  • step S110 the column 120 is moved slightly in the fixing direction.
  • This step is carried out if the first connector is arranged in such a way as to allow the column to move forward in the fixing direction while the connectors are in the fixing position, as in the embodiment represented by the Fig. 18 .
  • connector 100 is configured such that post 120 can move in the direction of attachment at step 110, which is the first step in the disconnect procedure. This movement allows the shoulder 139 to come push the tab 222 and cause it to come out of the notch 137. In step S120, the rotation of the column around its axis is thus facilitated.
  • FIG. 15 A second embodiment will now be presented in relation to the figure 15 .
  • This embodiment is identical to the first embodiment, except for the following point.
  • the same reference signs are used for the first and the second embodiment.
  • the column 120 is arranged as in the first embodiment except for its end. Consequently, the fixing passage 212 formed in the body 210 has a shape adapted for the specific shape that the pillar 120 has in this embodiment.
  • the dismantling surface 134 and the recessed surface 136 have the same radius R2, which is less than the radius R of the first shoulder 138.
  • connection and disconnection operations of the two connectors 100,200 to each other are the same in this embodiment as in the first embodiment.
  • the recessed surface 136 does not have to push the tab 222 radially, because the disassembly surface 134 and the recessed surface 136 are both surfaces of the same radius R2.
