  a cabinet or cabinet containing the corresponding equipment rack accordingly accordingly for each input line concerned.

  The constituent parts of the device are specified hereinafter one after the other.

  Figures 2 and 3 illustrate the sole 1. This sole 1 is constituted by a plate 10, substantially square, in the exemplary embodiment shown, the four corners are rounded. The rear face 1A of the device or the sole 1 has protrusions substantially identically. The plate 10 is provided with a peripheral rim 11, protruding on its two faces and very largely perforated by rear cutouts 11A and before 1B, allowing the circulation of a rear and front air space and a resulting protection of the device and of the equipment support with respect to moisture. The plate 10 is pierced with holes 12, here four in number and centered substantially along the four corners of an intermediate square which they define between them on the plate. These holes allow the attachment of the sole by screws not shown on a wall or wall. They are of oblong shape, the axis of each of which is obliquely on the two relevant sides of the intermediate square, for a possible final adjustment of the position of the sole just before its

  blocking on the wall or wall. A partial or total peripheral rim 12B around each hole protrudes on the only rear face 1A of the plate. These holes are also flared by a chamfer 12A on the front face.

  This plate is further perforated to define two sets of fins 13, these two games being arranged vis-à-

  screws and substantially centered on two of the opposite sides of the intermediate square defined by the four holes 12. Each set of fins is formed in a rectangular cutout 14 and connects the two small edges of the cut. This games

  13, a partial peripheral rim 14A around each cut 14 and two ribs 15 along the other two opposite sides of the intermediate square are protruding on the only rear face 1A of the plate.

  The fins are vis-à-vis a game to the other and each have a terminal tooth 13A, which is projecting on the rear face of the plate, parallel to this rear face, towards the central part, and defines a abutment shoulder 15 on the fin. They allow the possible fixing of the sole on a DIN type rail, not

  shown, whose section is U with the ends of its two branches folded outwardly of the U, these ends of the legs coming to fit between the plate 20 and the terminal teeth of the fins vis-à-vis.

  This plate further has passages 16 for the input line and dual output line conductors connected by the device. Two passages 16 are provided near each of the corners of the plate, on each side and respectively of each angle. They open on both sides of the plate and laterally through the peripheral flange 11. Two holes 17 for passage of a collar, not shown, are made between two passages 16 located near the same angle, for the maintenance to

  using such a collar drivers received in one and / or the other of these two passages 16.

  The plate also bears two studs 18 which are largely projecting on its only front face. These studs have their end bored axially. They allow the fixing of the hood on the sole, made using screws through the hood and received in their bore 18A. They also define the useful internal volume of the housing, while leaving an inner air gap between the plate 10 and the equipment support by provisions specified later. These studs also have, facing each other, a shoulder-shaped quasi-terminal portion forming an intermediate tooth 18B projecting over each of them and

  turned towards the inside of the plate 10. The two teeth 18B constitute between them and facing the plate a means of retention of the equipment support on the sole, this equipment support itself being provided with provisions corresponding to this effect.

  The sole is preferably made of plastic material and obtained directly by molding.

  The equipment support 4 is described in detail in

  look at Figures 4 to 5. It is received on the sole 1.

  It comprises: - a support assembly proper 20, which is removably mounted on the sole 1 and in particular has an elongate and substantially central housing 21, this housing being divided into a narrow part 21A and a wide part 21B and being open on the part and else on the front and rear faces of the support assembly and equipped to define, virtually directly in this support assembly, a female connector 22, - sets of connection contacts from the input line 25 to the output line 26, mounted on the support assembly on one side and the other of the housing extending therethrough, which are specified in more detail below and include in particular a first set of connecting contacts 27 for the an input line and a second set of contacts 28 for connection to the output line, these contacts 27 and 28 coming one elastically under pressure against the others inside the housing, in the rear part thereof, and extending first on one side of the housing and the second on the other side of the housing, - equipment mounted on this support assembly, which are, or define, exhaustively, firstly a connection module 30 for the input line, a filter module 31 of the RC type, parasite filtering on the input line 5, and a protection module 32 of the lightning arrestor type, connected to the input line contacts such as 27, the

  the surge arrester is further connected to a ground terminal 33 mounted for this purpose on the support assembly, and secondly two connection modules 35 and 36 for the output line. Among these devices, the protection module 32 and the associated ground terminal 33 may be optional.

  A protective plastron 37 covers the equipment assigned to the input line or at least their points

  connecting to input line contacts by contacts15 such as 27.

  This plastron 37 and the adpatator plastron 5 (FIG. 1B) may initially constitute a single piece of which the adapter plastron 5 is separable by breakage at a breaking initiation line 37A, to allow under these conditions the only maintenance in place the plastron 37 and the establishment of the adapted socket 7 (Figure 1C) in the housing 21. The support assembly 20 and the equipment and provisions provided in correspondence on this set

support are specified below.

  The support assembly 20 is insulating and directly molded and comprises a rear flat base 40, and groups of protruding partitions on the front face of the base and specified as and when, defining for some housing 21 and ensuring for d Other the separation and holding in place of the modules or their elements and contacts, these groups of partitions may be integral or not with each other and be reported on an initially independent base and pierced accordingly.35 The base 40 presents on its rear face ribs A slightly protruding, bearing on the sole described above leaving a blade of air between the base and the

  sole. Alternatively such spacing ribs may be provided on the sole.

  The base 40 is of smaller peripheral dimensions than those of the sole. It is simply said that the base is in a square side slightly greater than the distance between the two studs 18 of the sole. Two partitions 42 opposite and protruding on the base block under the teeth 18B of the studs 18 of the sole. Two indentations 43, in the edges of the base facing the partitions 42, guide and hold the support assembly 4 between the studs 18 of the sole. The housing 21 divides the base in two lateral parts, one on the left and one on the right of the housing. It is delimited by two non-referenced end partitions and by two left and right partitions 21G and 21D which constitute the edges of the narrow portion 21A. A first group of partitions 44 on the left side constitutes the body of the connection module 30. It is formed substantially parallel to the longitudinal direction of the housing, substantially facing its wide portion 21B. It corresponds to another partition 45, parallel and more external on the same left part, the front edge is indented and forms two notches 45A retaining by clamping the two conductors of the input line and a central lug 45B hooking The partition group 44 defines two parallel chimneys 44A, in which are mounted two self-stripping contacts 46 to which the conductors of the input line are connected. These contacts 46 are of conventional type and flat or alternatively are tubular and may belong to a connection system as such known and of the type described in FRA-2541049 or FR-A 2661 283. This same group of partitions 44 or module body 30 has two orifices

  44B, transverse to the chimneys 44A and located opposite the notches 45A, receiving the conductors of the input line.

  It receives a pusher 47 actuated by a screw 47A for its insertion into the chimneys ensuring the connection of the conductors to insulation displacement contacts. These self-stripping contacts 46 exit through the rear end of the chimneys

  and have a connecting lug 46A, or alternatively are welded to connection contacts, extending into grooves in the rear face of the base and connecting with the contacts 27, on the outside of the housing 21.

  Another group of partitions 48, following the partitions 44, is provided on the same left part of the base facing the left edge 21G of the narrow portion 21A of the housing. It forms with this edge a recessed terminal connecting the contacts 27 and 46 between them and with two output wires 31A, 31B of the filtering module 31. This connecting terminal designated by this reference 48 has two chimneys 48A, separated by the one of the partitions which are common to them, in each of which the end portions 20 of one of the contacts 27, one of the contacts 46 and one of the output wires 31A and 31B are connected by pressure against each other and are optionally further welded. For the protection module 32, constituted by a three-pole surge arrester of known type and having two lugs 32A of line protection and a ground lug 32B, provision is made, where appropriate, in the center of the left part of the base and on the outside of the connection terminal 48, a group of additional partitions 50 which constitutes the body of the ground terminal 33. This terminal 33 carries a ground jumper 33A crossed by a clamping screw 33B. She receives

  a ground lead not shown, which is connected to the ground jumper, as well as the ground lug 32B of the protection module 32 or a contact contact of the ground lug, locking between the ground jumper and the clamping screw .

  The protection module 32 is retained, essentially by its output tabs 32A and 32B, on a group of partitions 52 provided against the ground terminal. Its two tabs 32A are connected in this group of partitions 52 to connection contacts 51, the latter then extending under the base and being connected in particular by welding to the contacts 46, in the rear end of the chimneys 44A. These contacts 51 are as such known. They are of the folded flat blade type, having a slotted end of the clamping connection of one of the output tabs of the protection module 32 and having its other end lockable and / or weldable against

  one of the contacts 46 or alternatively against one of the contacts 27.

  The filtering module 31 is held against the end of the narrow portion 21A of the housing 21, by a group of partitions to which the partition 42 mentioned above. It is thus close to the connection terminal 48, for the possible direct connection of its outputs 31A and 31B to the contacts 27 and 46 in this connection terminal 48.20. The right part of the base carries two groups of partitions. 55 and 56, which are parallel and facing each other, the group of partitions 55 being between the housing 21 and the other group of partitions 56 and being more protruding than the latter on the base. These two groups of partitions constitute the body of the two connection modules 35 and 36 for the two conductors of the double output line 26. One of the partitions, denoted 55A or 56A in each of these groups, has two indentations 55B or 56B retaining the two conductors of each output line 30 received in the connection module. Each of these two groups of partitions 55 and 56 defines two internal chimneys denoted 35A or 36A according to the module 35 or 36, each chimney receiving a self-stripping lug marked 28B or 28C belonging to one of the contacts 28. Each receives in addition35 a double pusher 57 or 58 of known type, each with two split legs, complementary stacks, connected by a terminal bridge and equipped with a transverse orifice insertion driver, which are driven into the chimneys 35A or 36A. The contacts 27 and 28 are specified more particularly with reference to FIGS. 6 and 7 and their positioning and their functions with reference to FIGS. 4 and 5. The contact 27 is a spring blade having a U-shaped median portion 27M for bypassing in the front opening of the housing the left edge 21G thereof, this left edge being provided slightly less protruding than the right one 21D. One of the branches of the contact extends obliquely in the housing and has its end 27A naturally biased in the rear opening of the housing towards the right edge 21D. This same branch has an intermediate boss 27B, turned towards the right edge 21D and widely protruding into the housing, substantially beyond the median axis of the housing. The other branch of the contact has a fold 27C bearing against a shoulder of the outer face of the left edge 21D. It extends from this fold 27C substantially to the axis of one of the chimneys 48A, where it is divided into two side legs 27D and a central leg 27E. The central lug is shorter than the lateral lugs 27D and leaves the two lateral lugs integral with each other at their common end 27F. The central leg 27E extends to the front edge of the partition 48 opposite the edge 21G and is pressed against the front edge of this partition. It is then folded and arched above this partition in the front opening of the chimney 48A.30 It has on its arcuate end part a quasi-terminal boss 27H, which truncates its arcuate shape and

  whose concave surface is turned towards the interior of the chimney 48A and receives against it one of the output wires 31A or 31B of the filtering module 31.

  The lateral legs 27D are at their departure folded substantially on the central leg to extend substantially axially in the chimney 48A towards its

  rear opening, then they are arcuate having their end bearing against the edge 21G and being also biased against the opposite partition 48 at the level 5 of this rear opening.

  The tab 46A of each contact 46 is guided in the chimney 48A against the partition 48. It receives in pressure against it the arcuate end portion of the legs 27D and the arcuate opposite to the leg 27E. It holds by pinching the output wire 31A between its end portion and that of the leg 27E, in the front of each chimney 48A. The contact 28 is a flat blade, which has an end 28A folded in a loop on itself, inverted S, and has on its opposite end portion two lugs 28B and 28C having their end slit and insulation displacement. This contact is mounted in a groove 59 provided in the rear face of the base 40 and opening perpendicularly in the rear opening of the housing 21 and in that of one of the chimneys of each connection module 35 and 36. Its end 28A, comes perpendicularly under pressure on the end portion 27A of the corresponding contact 27 in the narrow portion 21A. Its two legs 28B and 28C come from substantially axial cutting of the initial contact blade 25 made from the end 28A for the leg 28B and from the leg 28B for the other leg 28C. They are bent substantially at 90 'on the contact and are received in one of the two chimneys of one and the other of the two connection modules 35 and 36. The tab 28B is longer than the tab 28C, the length each of the tabs corresponding to that of the chimneys of the corresponding module 35 or 36 This pressurization of the end portions 27A and 28A of the contacts 27 and 28, transversely to each other, in the rear part of the housing 21, allows the opening and the electrical isolation resulting from the input and output lines 26 normally connected. This is obtained by elastic deformation of the contacts 27 in the housing, when a male connector is plugged into the female connector 22 advantageously adapted to receive male connectors of standard types. The adapter plastron 5 is described with reference to FIG. 1B and FIG. 8. In this FIG.

  at the same time constitutes the protective plastron 37 connected to the adapter plastron 5 by narrow fasteners 37A constituting the rupture line between them and is designated with the latter under the overall reference 60.

  FIG. 8 shows, with reference to FIG. 4 or 5, that the protective plastron 37 is a simple plate coming mainly to cover the left part of the equipment support. It has latching tabs 37B and 37C, snapping under corresponding tabs such as the tab 45B of the partition 45 and a similar tab 53B provided another partition of the equipment support. The adapter plastron 5 extends the protective plastron on the front opening of the housing 21 and has a large rear shoulder 5B received in the wide portion 21B of the housing 21. It also has a small front shoulder 5C corresponding to the front opening 3 of the cover 2 (Figure 1A) and received therein when the cover 2 is in place. Its plug-in port 6 is centered in the housing and is of the type of that of a telephone connector female connector. It is of the same width as that of the narrow portion 21A of the housing 21, extends with the same width in the rear shoulder 5B and ends in the latter by a slightly wider end 6A, foolproof for the plug connector telephone. A lug 5F is provided on the front face of the rear shoulder 5B for clipping the adapter front plate 5 in the housing 21.35 The shoulder 5B in place in the housing 21 has no effect on the contacts 27 and 28 of the narrow portion 21A of this housing and thus on the lines 25 and 26 connected. The

  Female connector 22 equipped with this plastron 5 is thus made of a first standard type, the contacts 27 in the housing 21 simultaneously constitute the access contacts 5 of the female connector of this first type to the input line.

  FIG. 9 shows a male plug 62 of a telephone contact plugged into the female connector 22 equipped with the adapter plastron 5. This male plug 62 has a plug leg 63 carrying two unrepresented contacts on each of its two opposite lateral faces, for connection of this plug to a subscriber station via the connecting cord of the station equipped with such a plug. When this leg 63 is fully inserted through the access 6 of the adapter 5 in the housing 21, its end remains slightly recessed relative to the rear opening of the housing and the ends 27A and 28A of the contacts 27 and 28. The lateral contacts of one of the faces are in pressure on the contacts 27, against their boss 27B and their part going from this boss to the median fold 27M. The contacts 27 are retracted simultaneously in the housing 21, against the corresponding left edge 21G of the housing and have their end 27A distant from the end 28A of the contacts 28. The other two lateral contacts of the leg are in pressure against the right edge 21D of the dwelling and has no effect on the contacts.

  This plug is thus connected to the only input line concerned and this isolated input line of each corresponding output line, by cutting off the pressure connections of the ends 27A and 28A of the contacts 27 and 28.

  The adapted female plug 7 is described with reference to FIG. 1C and FIGS. 10, 11 and 12 and with reference also to FIG. 4 or 5 for its adaptation function of the female connector 22. It replaces the adapter plastron 5 mentioned above on the female connector 22, to define a female plug of a second standard type, which in this example is RJ45 type. The protection bib

  37 is maintained in place on the equipment assigned to the input line.

  It comprises an insulating body 70 extending the front plate 37 on the front opening of the housing 21 and having a narrow rear shoulder 70A received in the narrow portion 21A of the housing 21, a wide rear shoulder 70B received in the wide portion 21B of the housing 21 and a small front shoulder 70C received in the corresponding opening 3 of the hood 2 (Figure 1A) when this hood is in place. Its plug-in access 8 is defined through

  the front shoulder 70C in the wide rear shoulder 70B. It is divided into a front access 8A of the RJ45 type and a rear access 8B wider than the front access and open from both sides, in the front access and on the rear end of the shoulder 70B.

  The adapted female plug 7 is equipped with contacts traditionally accessible in the front access 8A. Among these contacts, two access contacts 77 have their first ends 77A resiliently free in the rear access 8B and their corresponding first terminal portions accessible in the front access. They also extend from the front access 8A into the narrow rear shoulder 70A by having opposite second end-to-end portions 77B protruding on a first one of the faces of this narrow shoulder. This adapted plug 7 is furthermore equipped with additional contacts 78, associated with the contacts 77. These contacts 78 have a first arcuate end portion 78A, constituting a bearing mouth for the first ends 77A of the contacts 77 in the rear access 8B, extend in the wide rear shoulder to bypass the rear access and lead to the second of the faces of the narrow shoulder 70A. They have their second ends 78B protruding on the rear end of the narrow shoulder

  rear 70A. A spacer 71 in the rear access 8B locks the first ends of the contacts 78.

  A lug 72 on the front face of the wide rear shoulder 70B allows the clipping of the adapted female plug

  in the housing 21 of the female connector 22 of the device (Figure 5).

  The function of this adapted plug 7 placed in the female connector 22 is explained with reference to FIGS. 10 to 12 and with reference also to FIGS. 5 and 9 for a better understanding of its function. It adapts the female connector 22 to make it conform to the type RJ45. It provides the connection of the contacts 77 and 27, by pressing the end portion 77B of one on the boss 27B of the others, and is thus connected by the contacts 77 and 27 to the input line. Simultaneously, it isolates the contacts 27 and 28 in the housing 21 by deformation of the contacts 27 pushed back to the edge 21G. It reestablishes the connection of the input and output lines by the contacts 78 whose ends 78B bear on the ends 28A of the contacts 28 and the opposite end portions 78A bear on the ends 77A of the contacts 77.20 In FIG. 12 , in dotted lines, a male plug 80, referred to as the second standard type RJ45, inserted into the front access 8A of the adapted socket 7 is shown. This plug 80 has a plug-in leg 80A complementary to the front access and equipped with 25 side contacts, not shown, which correspond to the contacts such as 77 accessible in the front access and which

  are connected to a subscriber station by a connecting cord carrying this plug. The spacer 71 in the overall access 8 constitutes a bottom insertion stop of the male plug in the front access 8A.

  During this plugging, the contacts 77 are connected to those corresponding to the plug 80 and are simultaneously pushed against the edge of the front access. The ends 77A of these same contacts 77 are then spaced from the ends 78A of the contacts 78, in the rear access 8B. As a result, the input and output lines, connected in the absence of the plug 80 in the access

  before, are then isolated. 81 has also been schematized on this RJ45 male plug its traditional locking handle in the front access, by abutment against the edge 5 opposite to the one carrying the accessible contacts in the front access.

  The exemplary embodiments illustrated and described above show that the female access connector 22, for each input line received by the termination device, is easily adaptable to different standard types of plugs, without thereby

  additional congestion resulting on the termination device. Of course this female access connector can be directly of a desired standard type.

  In the termination device, the female connector, adapted to one of the different standard types

  possible of plug, ensures the connection of the lines to be connected in the absence of complementary plug in the adapted female connector but isolates these lines when the plug 20 is plugged.

  In the termination device constituting a termination box, receiving several input lines and connecting these input lines to as many single or double output lines, it is simply stated that the female connectors for access to the different input lines are preferably aligned one after the other on the equipment support. The input lines are thus reviewed on one of the side portions of the equipment carrier and are physically separated from the output lines that depart from the other side portion, allowing for patching of subscriber station connections to the lines. and the isolation of the input and output lines concerned, by the female connectors receiving the plugs of the connecting cords of these stations.35 Of course, the embodiment illustrated in the drawings and described above has been given as a preferred example, the links of the various modules to the lines

  input and output can be obtained differently. In particular, the above-mentioned connection terminal 48 may be of the screw-clamping type of the contacts that it receives in each chimney on a support jumper.
