Definitions

  • the present invention relates generally to electrical connectors. It relates more particularly to a modular electrical connector, comprising a first plug-in connector, called socket and equipped with a row of parallel contact pins, which are accessible by a front opening of the socket, and a second connector, said terminal block and equipped with insulation displacement contacts, said insulation displacement contacts being connected individually on the one hand to said pins and on the other hand to the conductors of a multipair line. It also relates to a strip fitted with such connectors.
  • the socket for each of them is in particular a telecommunications socket of the standardized type, which is mounted as a wall socket and is used for the connection of terminal equipment to a user line connected to this socket.
  • the strips are also as such known. They allow the connection of lines of a network to user lines, on patch panels.
  • Document EP-A-0 583 486 also describes such a modular electrical connector, in which the terminal block extends on an upper face of the socket, from the front face to the rear face of the latter. Each plug pin and the insulation displacement contact are in one piece.
  • the socket and the terminal block comprise a common body, in one piece, in which the insulation displacement contacts are accessible along the two opposite lateral edges of the upper face, these two lateral edges being on either side of the open front face. of the common body.
  • the object of the present invention is to avoid such a drawback, by adopting a terminal block designed in a particular way to make its insulation displacement contacts accessible on the front face of the modular electrical connector.
  • a modular electrical connector comprising a first connector known as a socket and equipped with contact pins, said pins being mounted in a row in the socket, extending internally opposite a first wall of the socket and being accessible through an opening of a second wall adjoining the first wall and said front wall of said socket, and a second connector said terminal block external to said socket and equipped with insulation displacement contacts, said contacts being on the one hand individually connected to said pins and on the other hand each provided with a first terminal insulation displacement slot assigned to the connection of a conductor of a multipair line, characterized in that said insulation displacement contacts are aligned in a row in said terminal block and have all of the first insulation displacement slots opening out on the side of said front wall of the socket, substantially along a front edge common to said front wall of the socket and said terminal block, for a front connection of said conductors to the various first so-called front insulation displacement slots.
  • the present invention also relates to a strip equipped with such modular electrical connectors, characterized in that it comprises two rows of connectors, along which the connector sockets are external and the terminal blocks internal.
  • the strip comprises, in addition, a row of channels defined between the terminal blocks, each channel being common to two terminal blocks opposite two connectors of one and the other of the two rows of connectors, respectively.
  • the terminal block preferably has nine or ten insulation displacement contacts.
  • the terminal block 20 and the distributor 40 form a parallelepipedic extension on the socket, in this example substantially on the front half-part of the bottom wall 14 of the socket, being slightly protruding on either side of the socket.
  • the insulating body 21 of the terminal block is preferably in one piece with that 11 of the socket by directly defining the interconnection distributor or by defining a housing for its mounting when the latter is not directly integrated. Alternatively, it can simply be mounted against the bottom wall of the socket.
  • This terminal block 20 is flush with the front face of the socket, for the connection of the conductors 51 to the insulation displacement contacts by the front face of the terminal block and of the resulting modular connector.
  • the cable 50 enters via a rear access 61 of the shielding box 60, facing the rear face of the terminal block, this rear face of the terminal block being recessed internally relative to that of the socket.
  • This cable has a peripheral peripheral screen 52, which is directly connected to the shielding box in this rear access. It has its stripped end part, for access to the pairs of conductors 51 and to a ground wire 53 and their connection to the insulation displacement contacts 30 and 31 on the front face of the terminal block.
  • the socket 10 advantageously comprises a row of eight contact blades 17 mounted in its rear wall, on which the eight pins 12 come individually under elastic pressure, in the absence of male plug 70 inserted in socket 10.
  • These contact blades are signaling or ground contact blades.
  • they are, as the case may be, connected to an eight-conductor signaling cable entering via a second rear access 61 ′ of the shielding box, this second access rear shown closed then being open, or connected to the shielding box.
  • the pins separate from the blades 17 when the male plug is fully inserted into the socket.
  • the body 11 of the socket advantageously consists of a rear part 11A made of insulating material and a front part 11B made of conductive or semiconductor material, which are integral with one another .
  • the pins extend in the rear part 11A and pass through the lower wall 14 of the body substantially at the junction of the front and rear parts. They are retained in the rear wall of the rear part 11A, in an internal groove or a through notch, 15, by forming internal cambered elastic springs.
  • a flap 16 made of semiconductor material, closes the front opening 13 of the front part 11B. It is articulated around an axis 16A, provided on its edge located on the side opposite the pins. It opens on the inside of the socket, by direct action on it of a male plug 70, complementary to the socket, when this plug is inserted in the opening 13 and fully in the socket.
  • the shielding box 60 comprises a rear box 60A covering the rear part 11A of the body of the socket and retained thereon by engagement of a projection 18A provided on the rear part 11A in a corresponding lumen 62A on the rear housing 60A. It comprises a front convercle 60B, having a lower flap 64A engaging under the terminal block leaving a clearance between this flap and the terminal block, and an upper flap 64B received on the front part 11B.
  • the upper flap is retained on the upper wall of the front part 11B by a projection 18B of the front part engaged in a corresponding lumen 65B of the upper flap.
  • the cover is also retained on the rear housing 60A, on each side, by a side tab 66 which is inserted and locked at the rear of the terminal block under the side wall of the rear housing 60A.
  • a first window 67 to the right of the front opening 13 of the socket 10 and a second window 68 to the right of the front face of the terminal block are provided on this cover.
  • a protective cover 69 is mounted on the front face of the cover and closes the window 68. It is retained by snap-on fingers 69A, on the cover.
  • terminal block 20 and the insulation displacement contacts 30 or 31 thereof are described with more particular reference to FIGS. 4 to 7. It is noted that these figures are given on an enlarged scale compared to FIGS. 1 and 2 and that the comparative dimensions of the contacts or terminal block have not been observed between Figures 1 and 2 on the one hand and 4 to 7 on the other hand for greater clarity of the latter figures.
  • This contact 30 is twofold. It has two insulation displacement slots 32, 32 ', opposite and delimited between a pair of front arms 33A, 33B and a pair of rear arms 33'A, 33'B. These two pairs of arms are connected by the middle part 34 of the contact. Two returns are planned folded 35 and 36 along the contact, which are folded in one direction and the other respectively, define an acute angle of folding on the arms and the middle part and give the contact a Z-shaped section.
  • the insulation displacement contact 30 also comprises a set of three aligned holes 37, 38A and 38B, produced through the middle part 34 and the two folded returns 35 and 36.
  • Each hole has, as well as visible on the only hole 37, in the Figure 7, a circular shape 37A open in a narrow lumen 37B. These holes receive the terminal parts of the pins of the socket, after they have passed through the interconnection distributor, which are inserted and retained in each of them.
  • Punctures such as 39 made in the folded returns maintain the contact in place in the insulating body of the terminal block.
  • the insulating body 21 of the terminal block 20 has a row of front grooves 22 and a row of rear grooves 22 ', which are open lengthwise over the width of its respective front and rear faces.
  • front 22 and rear 22 'grooves are identical and generally straight in the insulating body. They are specified opposite one of the grooves 22.
  • Each groove 22 is delimited between two opposite sides 25A and 25B.
  • the flank 25A has two deflectors 26A and 27A projecting in one of the terminal portions of the groove.
  • the other side 25B has two deflectors 26B and 27B, projecting in a similar manner in the other end portion of the groove.
  • the two deflectors one after the other together define a local protuberance substantially S-shaped on the side concerned and limit the width of the end of the groove.
  • the contact in place in its grooves 22 and 22 'and the groove 23 between them, has its two arms at an angle in each groove between the opposite deflectors. It is held in abutment against the deflectors, by each of the projecting edges defined by the folded return on one of the arms.
  • This conductor is also pinched at the two ends of the groove.
  • insulation displacement slot is itself made at an angle and not transversely to the arms to penetrate and pass more easily through the insulation of the conductor.
  • the insulating body 11 comprises two holes 28A and 28B opening laterally in each Z-shaped groove 23, through which the pin to be connected to the contact is threaded.
  • the rear insulation displacement slot 32 ′ allows the use of insulation displacement contacts 30 in the bus network.
  • ground wire 53 of the cable 50 is forcibly connected to the insulation displacement contact 31, in the same way as the conductors 51 to the various insulation displacement contacts 30.
  • the contacts 30 and 31 in Z allow a particularly dense arrangement of these contacts in the terminal block.
  • FIG. 8 illustrates the interconnection distributor 40, to restore the order of the external wiring from the pins to the pairs of conductors, via the contacts 30.
  • these folds can shift the pins towards one and the other of the two lateral faces of the connector.
  • the insulation displacement contacts can be slightly modified and for example have only one side return or have two side returns folded in opposite directions but only one of which is pierced with a middle hole while the other not drilled forms a stop for the pin threaded through the contact.
  • FIG. 9 represents a strip according to the invention, formed of such connectors arranged in two rows facing each other and denoted 80A on one of the rows and 80B on the other.
  • the terminal blocks 20A and 20B define between them a row of channels 81, which are each common to the terminal blocks 20A and 20B of two connectors of the two rows respectively and are each assigned to two cables 50A and 50B or two multipair lines.
  • the pairs of conductors of the two cables 50A and 50B are connected to these two terminal blocks 20A and 20B, respectively.
  • the various cables, such as 50A, received in these channels constitute, for example, incoming lines of a network, which are connected to the different terminal blocks 20A.
  • the different cables such as 50B received in these same channels constitute output lines or user lines, which are connected to the various 20A terminals as desired.
  • a connector 80A can be connected to one of the connectors 80B by a jumper cord equipped with two complementary terminal plugs of the sockets 10A and 10B, as is well known for mixing between incoming and outgoing lines on conventional strips and therefore not shown.
  • stirring arrangements can be adopted between two strips, one then being assigned to incoming lines and the other to outgoing lines.
