Definitions

  • This disclosure relates to the field of electrical connectors. It relates in particular to electrical connectors designed to accommodate a plurality of electrical contacts in parallel passages provided in the connector, the center distance between neighboring contacts being very small.
  • a connector of this type is disclosed in particular by the document EP2056411 .
  • an electrical connector kit comprising an insert and a retainer, configured to be placed in a connection configuration in which they are fixed one to each other and constitute an insulating body.
  • the insert and the retainer are formed from an insulating material.
  • the insulating body is configured to accommodate a plurality of electrical contacts in a plurality of parallel passageways; each passage being arranged to allow a contact to be placed in the connection position by moving said contact in the passage forward in a connection direction.
  • the insulating body is configured so that, in connection position, the axes of the contacts are arranged in the same connection plane.
  • the insert For each of said passages, the insert comprises a channel with a U-shaped section, the U-shaped section being open in a transverse direction perpendicular to the connection plane.
  • the retainer comprises, for each of said passages, an elastically deformable retaining finger, able to be deformed by one of said contacts when said contact is placed in the connection position in the first passage, and to assume a connection position in the passage when said contact has reached its connection position, in which the contact is held in the chute and prevented from moving backwards by the retaining finger.
  • side flanges of at least one trough extend in the transverse direction beyond a limit in the transverse direction of a contact arranged in the connection position in the trough.
  • a contact When a contact is in the connection position, it is in one of the passages of the insulating body. It is then held in position by the insulating body.
  • the surfaces of the passage block all the degrees of freedom in translation and rotation of the contact, except the rotation around its own axis, and the translation along this axis (translation parallel to the X axis of the connector).
  • the direction of connection in which the contacts are mounted in the insulating body, is the direction of connection, directed in the forward direction.
  • the opposite direction is the reverse direction.
  • the retaining finger is arranged so that, if the contact tends to move backwards, an abutment surface of the contact then comes into abutment against the retaining finger. detention. This stop then blocks the contact and prevents it from moving further rearward.
  • connection kit (and therefore, when the insert and the retainer are in the connection configuration, the insulating body) may have all or part of the following improvements, individually or in any technically feasible combination:
  • the retainer includes at least one cover; and in the connection position, at least one of said chutes is closed by said at least one cover at least over a certain distance (or extent) in the direction of connection.
  • said distance may in particular extend rearwards from a plane of junction, perpendicular to the connection direction, and at which a front edge of said at least one cover is in contact with the insert.
  • the retaining finger(s) provided for one or more chutes are formed integrally with the cover(s) provided for this or these chutes.
  • At least one trough has a section that is substantially constant along the connection direction.
  • the insulating body is arranged such that in the connection position, at least one chute, and preferably all of the chutes extend(s) as far as an opening provided at the rear of the retainer.
  • a side flange of a chute is integrally formed with a side flange of an adjacent chute, or a portion of a bottom of a chute is integrally formed with a portion of a bottom of an adjacent chute.
  • the retainer is integrally formed.
  • the present disclosure also includes an electrical connector made from the kit for electrical connector defined above.
  • the electrical connector includes a housing, in which at least a portion of the insulating body is mounted.
  • the insert when the connector is made, the insert is then generally inserted (at least partially) into the housing. This is why the term 'insert' is used. However, in this document, this term 'insert' refers to any mechanical part, only configured to carry out the indicated functions.
  • the insulating body has sufficient mechanical strength for the use of a casing to be unnecessary: the connector is then configured to be used without a casing.
  • the other functions performed by the box such as, for example, maintaining the insulating body in position relative to other parts (for example, maintaining it on a printed circuit, maintaining it in position relative to another connector complementary, etc.) can be made by the insulating body itself.
  • the expression 'the insulating body' designates the assembly comprising the insert and the retaining piece, in the connection configuration.
  • a feature of the form “the insulating body is arranged such that" can therefore interchangeably be replaced by a feature of the form "The insert and the retaining piece are arranged such that, when 'they are attached to each other in connection configuration, ....'.
  • a connector according to the present disclosure uses a retaining piece of insulating material, which attaches to the insert so as to constitute an insulating body within the connector. Due to its insulating body, comprising an insert and a retaining piece, both made of insulating materials, the connector according to the present disclosure does not require the use of metal parts to maintain the contacts. It follows that it reduces the possibilities of signal interference between adjacent contacts, and in the end provides better insulation of the contacts compared to connectors of known type.
  • the insulating body is preferably constituted solely by the insert and the retaining piece.
  • an electrical connector 1 This comprises a housing 10, an insulating body 20, and a set of electrical contacts 70 (the reference 70 denotes either, depending on the context, an individual contact or all of the contacts).
  • the connector 1 does not include a casing.
  • the electrical connector has an axis X parallel to the axes of passages 22 provided in the insulating body 20 to accommodate the contacts 70.
  • X+ the direction in which the contacts 70 are introduced into the insulating body 20 defines a connection direction X+, arbitrarily called 'forward direction', the opposite direction or disconnection direction being denoted X- and called 'reverse direction'.
  • the Y and Z directions perpendicular to the connection direction are called 'transverse directions'.
  • connector 1 For ease of understanding, the configuration of connector 1 will be described assuming that the X direction is horizontal and the Z direction is vertical, allowing reference to top, bottom, etc. However, it is quite obvious that the connector can have any orientation.
  • the connector 1 is a first connector, intended on the one hand to be fixed to one end of a multi-conductor electrical wire (not shown), and on the other hand to be fixed with a corresponding second connector (not shown). When it is fixed to the electric wire and to the second connector, the connector 1 ensures the connection of each of the conductors of the electric wire with corresponding contacts of the second connector.
  • the connector 1 comprises 9 contacts 70, divided into two rows: an upper row of 5 contacts, and a lower row of 4 contacts. Each of these two rows of contacts extends in a plane called the 'connection plane'.
  • the connection plane of the upper row of contacts is denoted PC.
  • the two connecting planes are parallel.
  • the spacing between neighboring contacts can be small, for example less than 1.5 mm, or even less than 1 mm, or even less than 0.7 mm.
  • Each contact 70 is elongated, and in this case are identical to each other.
  • Each contact 70 in a manner known per se, comprises two parts: a strand 72 and a body 80.
  • the body 80 is formed from a metal alloy by cutting: thus, as seen in the figure 6 , the body 80 is essentially rotationally symmetrical.
  • the rear part 82 of the body 80 is intended to be crimped onto an electrical conductor, while the front part 84 of the body 80 is intended to be crimped onto the strand 72.
  • the body 80 also has a circumferential locking groove 86, the role of which will be explained below.
  • the insulating body 20 comprises an insert 30 and a retaining piece 50 configured to be fixed to each other by interlocking (they are clipped to each other). Each of them is formed by plastic injection in insulating material.
  • Part 50 consists essentially of a sleeve 54, inside which extend retaining fingers 56.
  • the insulating body 20 is traversed by parallel passages 22 (one passage per contact 70) which extend along the connection direction X.
  • the passages 22 form two rows of parallel passages 22.
  • Each passage 22 is open at both ends.
  • the rear end allows the introduction of the contact 70.
  • the front end, open, allows the introduction of a female contact (not shown) of the second connector, which is then in electrical contact with the contact 70 when the connector 1 is connected to the second connector.
  • the insert 30 has three parts: a front part 32, a junction part 34 and a separator 40.
  • the front part 32 generally has a constant section along the direction of connection, in the outer shape of a trapezium, pierced with 9 holes of circular section, namely one hole for each of the passages 22. Each passage 22 crosses the insert 30 right through. passes through each of its three parts.
  • the outer surface of the front part 32 is provided to allow the blocking of the insulating body 20 in the casing 10 (the insulating body 20 is force-fitted in the casing 10).
  • the junction part 34 connects the front part 32 to the separator 40. It has a circumferential surface 36, provided to receive the front edge 52 of the sleeve 54, and thus to allow the attachment of the retainer 50 to the insert 30.
  • the separator 40 in the embodiment shown, is formed by the combination of nine chutes 44, namely five upper chutes 44A and four lower chutes 44B.
  • a chute 44 (an upper chute 44A).
  • the chute 44 has a constant section along the direction of connection. This section is 'U' shaped.
  • the chute therefore has two side wings 44L, a bottom 44F and an opening 440.
  • a retaining finger 56 is disposed in the opening 440 of the 'U'. This preferably extends from one side flange 44L of the chute to the other (in the Y direction).
  • the chute extends a certain distance forward to the junction part 34 of the insert. It joins the junction part 34 at a junction plane PJ ( Fig.7 ). At the level (along the direction of connection X) of this plane, and over a short distance in front of this plane along the direction X+, outside the chutes 44 (and therefore overall of the separator 40), the front edge 52 of the sleeve 54 is in contact with insert 30 and ensures the junction therewith.
  • the opening 440 of the chute is oriented in the transverse direction Z, namely upwards (direction Z+) for the upper chutes 44A, and inversely downwards (direction Z-) for the lower chutes 44B.
  • the side flanges 44L of adjacent chutes are combined and integrally formed in one piece.
  • a portion of the bottom 44F of the upper chute is combined and integrally formed (monobloc) with a portion of the bottom of the adjacent lower chute.
  • the different chutes 44 are therefore combined so as to constitute a part of the insert 30, called separator 40, formed in one piece.
  • the entire insert 30, in this embodiment, is integrally formed.
  • the sleeve 54 has a generally constant section along the direction of connection.
  • Each of the retainer fingers 56 is fixed inside the sleeve 54, and preferably is formed integrally (or in one piece) with the sleeve 54.
  • the assembly of the retainer 50 is therefore preferably formed of a single piece (one-piece part), in particular by plastic injection.
  • the sleeve 54 has a hollow transverse section, of generally rectangular shape. This makes it possible to place the separator 40 in the retainer 50, in the connection configuration.
  • the opening part 50 has a front opening 54av and a rear opening 54ar, provided for passing the separator 40.
  • all of the chutes extend inside the sleeve 54, and in particular extend to the opening 54ar arranged at the rear of the retainer 50.
  • the sleeve 54 has an upper wall 54A, a lower wall 54B and two side walls 54C and 54D.
  • the upper wall 54A acts as the upper cover and the lower wall 54B acts as the lower cover, the role of which will be explained later.
  • the edge 52 of the sleeve 54 comprises an upper part which constitutes the edge of the upper cover 54A and a lower part which constitutes the edge of the lower cover 54B.
  • Retaining fingers 56 extend from top and bottom covers 54A and 54B. They extend from these covers in an oblique direction, both forwards (X+) and towards the connection plane PC (direction Z or Z+ as the case may be).
  • a retaining finger is associated with each of the passages 22 and has the function of retaining, that is to say of blocking, a contact placed in this passage 22 so as to prevent this contact from coming out. of the connector to the rear.
  • Each retaining finger 56 has the shape of a small elastically deformable tongue, which extends from one of the covers 54A or 54B in the vertical direction. Each finger 56 starts from one of these covers, and gradually approaches the PC connection plane as one moves in the direction of connection X+ along the finger 56. As seen in section longitudinal ( Fig.4 ), the end of the finger forms an abutment surface having a perpendicular direction directed along the connection direction X+.
  • the casing 10 provides the mechanical protection of the insulating body 20. In a manner known per se, it comprises means for fixing to the second connector. It has an interior passage configured to accommodate and hold the insulating body 20.
  • the assembly of the connector is done as follows.
  • the contacts 70 are mounted beforehand and fixed to the end of an electric wire (not shown).
  • the insulating body 20 is mounted by fixing the retainer 50 to the insert 30.
  • the insert 30 is inserted into the sleeve 54, its surface circumferential 36 coming to block inside the front edge 52 of the retainer 50.
  • the insulating body 20 is introduced and fixed in the casing 10.
  • each contact 70 is then introduced into the opening 54ar formed at the rear of the sleeve 54. More precisely, each contact 70 is guided so as to be introduced into one of the passages 22, with which it is therefore associated.
  • the contacts are then moved in translation in the passages 22 until they reach the connection position represented on the Fig.4 .
  • each contact 70 comes into contact with a retaining finger 56.
  • the finger 56 being deformable, it is pushed back by the front end of the contact 70 (by a strand 72); it therefore deviates from the contact 70 by moving away from the connection plane PC and approaching the upper or lower internal surface (as the case may be) of the sleeve 54 to which it is fixed.
  • This movement of the finger 56 therefore allows the contact 70 to pass through the passage 22 axially at the level of the retaining finger 56, by moving in the connection direction X+.
  • the groove 86 is formed by an abutment surface 87 and a bottom surface 88. As seen in longitudinal section ( Fig.4 ), the abutment surface has a perpendicular direction directed along a direction X- opposite to the connection direction X+.
  • the bottom surface 88 connects the bottom of the groove 86 to the outer surface of the rear part of the body 80.
  • the elastic finger 56 then prevents the rearward exit of the contact 70.
  • Connector 1 is then in the connection configuration, and can be attached to the second connector.
  • the contact 70 can be disassembled.
  • a so-called 'pen' tool is introduced from the rear into the passage 22 which is inserted, in the passage 22, between the outer surface of the contact 70 and the finger 56. This tool is moved in the direction of connection until it forces the finger 56 to lift and thus disengage from the abutment surface 87.
  • the contact 70 can then be withdrawn from the insulating body 20 towards the rear. Then (or even simultaneously), the tool is removed.
  • THE Figs.5 and 6 represent a transverse section of the connector 1, in the connection position.
  • the side flanges 44L of the chute extend in the transverse direction Z+ to a position LL. Furthermore, the contact 70, following this same transverse direction Z+, extends to a maximum position, or limit, LC. In the transverse direction Z+, the limit of the lateral flanges 44L, located at position LL, is beyond the limit of contact 70 located at position LC. Consequently, in the connection position, the contacts 70 are separated from each other by the side flanges 44L of the trunking, and are therefore not directly opposite each other: this arrangement therefore reduces the risk of spark or short circuit.
  • the upper and lower walls 54A and 54B play the role of covers for the trunkings 44.
  • these walls are arranged so that in the connection position the trunkings 44 are closed by the walls 54A and 54B. This closure of the trunking occurs at least over a certain part of the connector 1, which extends over a certain distance along the connection direction X.
  • a chute 44 is closed by a cover means that, on the part of the connector concerned, in a transverse section, the passage 22 passing through the chute is entirely delimited by the chute 44 and the cover in question (54A or 54B according to the case).
  • the periphery of the passage 22 considered is therefore in this case constituted solely by insulating material. Thanks to this, on this part of the connector, in the connection position, the risk of short-circuiting between contacts is in principle non-existent.
  • the part of the connector at which, in the connection position, the troughs 44 are closed by the cover (54A, 54B), preferably extends over the entire length of the troughs in the connection direction. This part extends in particular preferably from the junction plane PJ, perpendicular to the connection direction, at which the front edge 52 of the covers is in contact with the insert 30.
  • the contacts 70 remain separated from each other by the side wings 44L of the troughs 44.
