Description

The present invention relates to the field of connectors electric. It applies in particular to connectors for networks corporate premises with a high flow of information.

Since the beginning of the last decade, we have witnessed a significant increase in information rates on local networks of companies, seeing the corresponding base frequencies pass 100MHz in 1990 to 600MHz in 1997.

This evolution leads to a strong demand for creations of new cables and new connectors associated with the need for market thus defined.

In practice today, those skilled in the art generally classify the connectivity for local networks of companies with high information flow in three sections.

The first and second headings respectively group the connectors working at 100MHz and 250MHz. These connectors use cables of four pairs of 100 Ohms, see 120 Ohms, or without shielding either in common shielding using metallized plastic tape twisted around the pairs. In some cases, a mass drain is added. Finally, in the best of EMC cases, a braid is arranged additional way above the ribbon layer.

The third section groups together the connectors working at 600MHz. It uses cables of four pairs of 100 Ohms or even 120 Ohms. These pairs must be shielded separately via a metallized plastic tape. A common shield made up either of additional taping, either of a braid, or if necessary of the combination of such additional tape and braid, covers pairs.

One of the problems posed today would be to have electrical connectors compatible with an RJ45 type interface.

Admittedly, attempts in this direction have been envisaged by specialists. In particular, systems have been proposed incorporating switches in a base suitable for enabling dynamic switching allowing to modify the localization of the pairs of wiring used.

However, such a solution is not entirely satisfactory. In particular, it is both expensive and of questionable reliability.

The present invention now aims to provide a new connector system including a socket-plug couple RJ45 compatible.

Another object of the present invention is to provide a system connector without internal switching.

Another important object of the present invention is to provide a connector system capable of receiving different categories of connectors.

Another object of the present invention is to provide a system of connectors suitable for mounting as well as access point faceplate than in patch panel.

These objects are achieved in the context of the present invention by to a connector comprising an electrically insulating housing which receives a contact carrier body which insulating housing has a series of windows suitable for receiving self-piercing contacts in various configurations of connectors and in particular a first configuration in which all functional self-piercing contacts in terms of connections are accessible on a common face of the contact carrier body and a second configuration in which self-piercing contacts functionally connected are accessible on two sides opposite of the contact carrier body.

According to another advantageous characteristic of the present invention, some of the self-piercing contacts engage with a electrically conductive portion of the contact carrier body to thereby define in combination with this a cross forming armor on the plan electromagnetic.

According to another advantageous characteristic of the invention, the self-piercing contacts have variable heights allowing to increase the distance between the pairs of associated wires, compared to a arrangement based on self-piercing contacts of identical height, for thus improve the crosstalk criteria.

The connector plug 100 illustrated in FIG. 1 attached essentially comprises an internal body 110 of electrically material conductor, associated with four wire guides 130 of electrically material insulating, a front part 140 of electrically insulating material, a part rear or cover 170 and self-piercing contacts 190.

The body 110 is essentially composed of a cross 112 framed by two side cheeks 113, 114 parallel to each other, and on a front axial end of the spider a support plate 116 aligned on one membranes of the cross 112 and orthogonal to the lateral cheeks 113, 114 itself framed by two lateral flanges 117, 118 also orthogonal to the cheeks 113, 114. The cross-member 112 thus defined in cooperation with the side cheeks 113, 114 four shaped sockets 111 electromagnetic tunnel suitable for receiving one of the so-called wire insulation 130.

The support plate 116 is provided on one of these faces which are here qualify as the upper face of a group of conductive cradles 120, preferably four cradles in the form of longitudinal grooves. More specifically, it is thus preferably provided two central cradles of shallow depth framed on each side by a cradle 120 lateral of greater depth. These cradles 120 are intended for receive a self-piercing contact 190 as will be specified later.

The support plate 116 is provided on its sides with lugs or pins 122 suitable for cooperating with lights 149 formed on the front part 140 to immobilize the body 110 in the front part 140. Similarly, the side cheeks 113, 114 include lugs or nipples 124 of their own to cooperate with lights 179 formed on the cover 170 for immobilize the body 110 relative to the cover 170.

Each of the wire guide insulators 130 includes an extended block 132 forward by a tab 134 of smaller section. Each block 132 is crossed by two longitudinal boats 136, 137 suitable for receiving a pair. These channels 136, 137 extend in the form of cradles longitudinal 138 aligned on one of the surfaces of the tongues 134.

As can be seen in FIGS. 1, 2 and 9, the tongues 134 of the two wire guide insulators 130 intended to take position in the cells upper 111 are offset from block 132 to take position respectively on either side of the cradles 120 provided on the support plate 116.

Similarly, the tongues 134 of the two wire guide insulators 130 intended to take position in the lower cells 111 are offset relative to block 132 so as to come adjacent to the longitudinal edges of the support plate 116.

The cells 111 are designed to receive the shields individual of each pair. Note also on examining Figures 2 and 9 in particular that the support plate 116 is provided on its lower part an orthogonal longitudinal central member 115 extending the second membrane of the cross 112 to thus extend this cross forming electromagnetic shielding.

The insulating front part 130 is designed to fit onto the body 110 and be held thereon by the cooperation of lights 149 and of the aforesaid nipples 122. This insulating front part 140 is generally conforms to the known RJ45 interface.

The insulating front part 140 has the general shape of a cage composed of four walls 142, 144, 146 and 148 respectively orthogonal and parallel to each other two by two.

The bottom wall 144 carries a locking tab 145 classic in itself conforms to the RJ45 application and therefore will not described in detail below.

The insulating front part 140 is designed to receive eight contacts 190 self-piercing at the top and four 190 self-piercing contacts in the lower part.

For this purpose, the upper wall 142 has eight windows 143 straight parallel parallel and equi-distant, through, adjacent to its front end. The width of the windows 143 is complementary to the width of the self-piercing contacts 190.

The distribution of windows 143 is adapted so that the 190 associated self-piercing contacts are placed opposite the cradles 120 and 138 above.

Similarly, the bottom wall 144 has four windows 143 suitable for receiving the four lower 190 self-piercing contacts placed respectively opposite the cradles opening onto the tongues 134 lower wire guide insulators 130.

The rear cover 170 is preferably made of material electrically conductive. It is suitable for covering the whole formed by the body 110 and the front part 140 until near the self-piercing contacts 190. The cover 190 has the general shape of a cage composed of four walls 172, 174, 176, 178 respectively orthogonal and parallel two by two. The side walls 176, 178 extend beyond the walls main 172, 174 in the form of cheeks 177, so that the walls main 172, 174 do not cover the self-piercing contacts 190.

The cover 170 is held on the body 110 thanks to the cooperation defined between lights 179 and nipples 124.

Hood 170 provides mechanical strength and electrical continuity of the common shielding of the cable by deformations or crimps formed for example in the main walls 172 and 174 and referenced 171 on the attached figures. In addition, preferably, the cover 170 comprises additional deformations referenced 173, for example in its main partitions 172, 174 to keep the shields in contact individual pairs. If necessary, a cuff or overmolding (not shown in the figures to simplify the illustration) can reinforce still the mechanical strength of the cable in the rear part of the cover 170.

To use the plug of the type illustrated in Figures 1 to 9 attached, we proceed essentially as follows.

After cutting the individual shielding of each pair on about 7mm, we introduce the insulated wires of each of these pairs in the wire guide insulators 130 (two per pair) until they stop at the bottom of the channel opposite the front part 140. The self-piercing contacts 190 are then inserted into the windows 143 so that as they cross the wires, thus ensuring electrical contact with the souls of these. The pairs are therefore arranged in the continuity of the alveoli 111 occupying the diagonal positions of the connector and using by Consequently, in the upper part, the two extreme contacts 190 on the right and the two extreme contacts 190 on the left, and in the lower part the four contacts 190 located approximately opposite to the aforementioned contacts of the upper part.

The four central contacts 190 of the upper part are therefore not not wired.

These four central contacts 190 penetrate into the cradles 120 of the support plate 116 and thus make it possible to extend the front of the spider forming electromagnetic shielding 112 in the form of a first membrane 116 extending one of the membranes of the cross 112 and a second orthogonal membrane, extending the second membrane of the cross 112, and formed itself, in the lower part, by the frame 115, and in the upper part by the four self-piercing contacts 190 central offices. This appears in particular in Figure 9.

Thus, when the connector is covered by the cover 170, the latter extends, in cooperation with the support plate 116, the four contacts central self-drilling 190 and the lower chord 115, the tunnel effect electromagnetic generated by the cross 112. It should be remembered here that the four central self-piercing contacts 190 at the top are connected to the mass by their engagement in the longitudinal cradles 120 formed on the support plate 116.

It should also be noted that, as can be seen in particular on the Figure 2, the end wall 150 of the front part 140 has a opening 151 in T complementary to the support plate 116 and the lower chord 115 so that when coupling the plug 100 in a complementary base, such as the base 300 shown in Figures 15 and following the shielding thus defined ensures the joint plane electromagnetic with a cruciform shielding of this base.

We will now describe the variant embodiment of the sheet 200 illustrated in Figures 10 to 14.

The elements of this sheet 200 similar or functionally equivalent to elements of sheet 100 previously described opposite Figures 1 to 9, will include incremented numerical references of 100.

We find in Figures 10 to 14, a sheet formed by the combination of a body 210, a front part 240, self-piercing contacts 290 and a cover hood 270.

The front part 240, the cover 270 and the self-piercing contacts 290 conform to those described above with reference to FIGS. 1 to 9.

The card 200 illustrated in FIGS. 10 to 14 stands out essentially sheet 100 illustrated in Figures 1 to 9 by the fact that it comprises a body 210 of electrically insulating material.

This body 210 comprises at the rear a cage in the general shape of U comprising a bottom wall or core 212 framed by two wings lateral orthogonal 213, 214. At the front, this cage is extended by a block 216 provided with longitudinal channels passing through 218, preferably eight channels crossing.

Finally, on the front of the block 216, the body 210 includes a plate longitudinal median 220. This is provided on its upper surface of cradles or longitudinal channels 222 respectively aligned on the channels 218 crossing block 216.

As can be seen in Figures 10 and following preferably, thus provided three pairs of channels 222 having a depth identical distributed in the form of two pairs of lateral channels and one pair of central channels between which a channel referenced 222a of greater depth. Channels 218 are respectively aligned on a cradle 222. Thus it is provided in the block 216 three pairs of channels crossing 218 located at the same altitude and between these three pairs of coplanar channels respectively a channel 218a, at a lower altitude.

The two cradles 222a and channels 218a of lower altitude are intended to receive self-piercing contacts 290a of higher height.

Comparably to the first embodiment illustrated on Figures 1 to 10, each self-piercing contact 290 has the general shape a U comprising a core 292 accessible on the outside of the connector after assembly, secured to two wings 294 with tapered ends, generally parallel to each other and orthogonal to the core 292, suitable for penetrate the insulation of each respective associated conductor.

The body 210 is held in the front part 240 thanks to the defined cooperation between the lights 241 provided on the sides of the part before 240 and additional pins or lugs 223 provided on the sides of block 216 and plate 220.

Similarly, the body 210 is held on the cover 270 by the defined cooperation between the lights 179 provided on the sides of the cover and lugs or nipples 224 provided on the sides of the U-shaped cage of the body 210.

In a way comparable to the first variant illustrated on the Figures 1 to 10, the plate 220 is provided on its lower surface with a vertical frame 215. This, like the front end of the plate 220 enters the T-slot 251 of the front part 240.

To use the plug 200 illustrated in Figures 10 and following we essentially proceeds as follows.

After cutting the sheath and the common shield of the cable on about 10mm, we introduce the insulated wires of each of these pairs in the holes 218 until they stop at the bottom of the guide channel associated with the front part 240. The contacts 290 are then pressed so that they cross the wires ensuring electrical contact with the souls of these. Only the eight contacts 290 in the upper part are in electrical contact with the wires. The four contacts 290 at the bottom are also crimped but do not make any electrical contact.

The cover 270 is then placed on the assembly as described previously for the first variant in accordance with FIGS. 1 to 10.

Note also that it is essential in the context of most of the applications targeted by the invention to minimize the crosstalk in the high frequency bands used. By nature, crosstalk is directly proportional to the mutual field induction between pairs and inversely proportional to the square of the distance between them.

In this context, according to the present invention, to minimize the crosstalk is planned a double measure: on the one hand, a interlacing of the pairs at the level of the contacts 290 used, and on the other hand a disposition at different altitudes of the wires, resulting from depth different from the associated cradles 222 and associated channels 218, as described previously.

Precisely still in the context of the present invention, it is preferably use the following wiring sequence: first pair: one contact 1 and 2, second pair: a contact 3 and 6, third pair: a contact 4 and 5 and finally fourth pair: a contact 7 and 8. Thus, the second pair is dissociated between the other three pairs.

Furthermore, to find an acceptable crosstalk, this pair is moved vertically, relative to the other contacts. As seen in Figure 14, thanks to this arrangement, and the use of self-piercing contacts 290a, higher than the others contacts, associated with the second pair, this one is moved in the direction vertical and a greater distance is thus obtained between contacts 3 and 2, 3 and 4, 6 and 5, and finally 6 and 7 with respect to the distance which would be obtained in case of co-planar wires.

We will now describe the base 300 illustrated in FIGS. 15 to 18. Elements thereof identical or functionally equivalent to elements of the sheet illustrated in Figures 1 to 10 will bear numeric references incremented by 200 with respect to the elements previously described with reference to FIGS. 1 to 10.

The base 300 illustrated in FIGS. 15 and following includes essentially: an electrically insulating rear connection block 310, associated with two inserters 330, an electrically interfacial block before insulator 340, associated with a spider 350, a set of contacts 390 and a cover cover 370.

The front interfacial block 340 is hollowed out in the front part of a shape 342 corresponding to the RJ45 application and intended to receive the plug 100 previously described maintained by its latch 145 in a part of locking 343 of the base 300. Such an RJ45 interface being known in itself will not be described in detail later.

The rear part of the interfacial block 340 has eight at the top cells passing longitudinally through 344 and in the lower part four cells crossing longitudinally 346. These cells 344, 346 are intended to receive and position eight high contacts 390 and four respectively 390 low contacts. These 390 contacts provide electrical continuity with contacts 190 of plug 100.

Preferably, each contact 390 comprises a part of elastic connection in general U-shape composed of two branches 392, 394, V-shaped or dihedral. The front part of these branches 392, 394 is accessible on the front of the base 300 in the form 342 so that when engaging a record 100, the two branches 392, 394 enter an associated window 143, 243 of the file, come into abutment on a contact 190, 290 and are requested to reconcile.

One of the branches 392 of each contact forming a common trunk, of greater length, is provided at its rear end with a perpendicular extension 396, U-shaped, serving as contacts self-stripping, in a conventional manner per se. Such self-stripping contacts 396 will not be described in detail later. We recall simply that when an electrical wire having an electrically conductive core conductor coated with an insulating sheath is inserted on such a self-stripping contact 396, the two branches of this self-stripping contact 396 insulates the insulating sheath to guarantee contact between the core electrically conductive and the branches of the self-stripping contact 396, and thereby with contact 390 in its entirety, the distance between the two branches of the self-stripping contact 396 being less than the diameter of the electrically conductive core of the wire in question.

The insulating rear connection block 310 is designed to be intimately assembled with the interfacial block 340 by any means mechanical, such as, not exhaustively clipping, and thus ensures the continuity. The connection block 310 has eight cells in the upper part 312 and in the lower part four cells 314, respectively aligned with the cells 314 and 346 of the block 340. These cells 312, 314 receive and block the rear parts of the 390 contacts. At the rear of each of these cells 312, 314, there is preferably a hollowed-out detail for receiving the aforesaid self-stripping part 396. Each of the inserters 330 is formed preferably a plate 332 provided with a series of ribs protruding parallels 334 positioned to be aligned respectively with the sockets 312, 314 in order to solicit each pair of wires in engagement with the self-stripping contacts 396, in a manner known per se.

Note also that the interfacial block before 340 and the block of rear connection 310 are each provided with a pair of windows crossed crossings 348, 349 and respectively 318, 319 specific to receive the additional cross 350 made of electrically material conductor and formed of two crossed members 352, 354.

To use the base 300 illustrated in FIGS. 15 and following, we proceed essentially as follows.

The individual sheath of each pair is stripped for about 5mm. Each wire is introduced into the recesses 312, 314 of the rear part 310. The wires are pushed by the inserters 330 into the cells and the self-stripping parts 396 of contacts 390 thus establishing contact electric with the core of the wires by piercing insulation.

The electrically conductive cross 350 is introduced into the cruciform grooves 348, 349 and 318 and 319 practiced in the block interfacial 340 and in the rear connection block 310. The cross 350 is held in place by any suitable mechanical means. It ensures the effect of tunnel electromagnetically separating the four pairs to ensure the link with plug 100. As for plug 100, the pairs are diagonally opposite which are connected either the two pairs extremes of the upper part and the two pairs of the lower part.

The arrangement of these pairs and therefore of the cells 344, 346, 312, 314 and corresponding 390 contacts obviously coincides respectively with the arrangement of the functional 190 contacts on the plan used in plug 100.

The cross 350 receives the individual shielding of the pairs in the part protruding from the rear of the connection block 310 and ensures its continuity electric mass.

Finally, the cover 370 made of electrically conductive material comes cover the body of the connector formed by the two blocks 310 and 340, completing the tunnel effect. It thus ensures electromagnetic continuity with the common shielding of the cable. In addition, it mechanically holds the cable.

When coupling the base 300 with the plug 100, the cross 350 ensures by electromagnetic continuity with the body 110 of the plug thus guaranteeing the transmission performance.

We will now describe the second variant of base 400 illustrated in FIGS. 19 and following.

This base 400 is intended to receive the plug 200 illustrated on Figures 11 and following.

The elements of the base 400 illustrated in FIGS. 19 and following similar or functionally equivalent to elements of the base 300 illustrated in FIGS. 15 to 18 will bear references digital increments of 100 with respect to base 300 previously described.

• elle possède une croix 450 électriquement isolante et non pas électriquement conductrice, qui a uniquement pour but de renforcer la rigidité de l'ensemble, et
• le câblage s'effectue en raccordant les fils de paires sur les huit contacts 490 de la partie supérieure, les quatre contacts 390 de la partie inférieure n'étant pas utilisés électriquement.

The base 400 illustrated in FIG. 19 differs essentially from the base previously described with regard to FIG. 15, by the fact that:

• it has an electrically insulating and not electrically conductive cross 450, which has the sole purpose of reinforcing the rigidity of the assembly, and
• the wiring is carried out by connecting the pair wires to the eight contacts 490 of the upper part, the four contacts 390 of the lower part not being used electrically.

Furthermore, here again, the conductive hood 370 ensures continuity electromagnetic with the common shielding of the cable in the case of a shielded wiring with screen continuity. In addition, it maintains mechanically this cable. In the case of wiring using an unscreened cable, the cover conductor 370 is used only for mechanical support.

A connector has been illustrated in FIG. 20 in longitudinal section. according to the present invention formed by assembling a plug 100 in a base 300.

The base 300 composed of the interfacial insulating block 340 and the block rear connection 310 receives in cavity 342 compatible with RJ45 the insulating front part 140 also compatible with RJ45 of the plug. The locking between base 300 and plug 100 is ensured respectively by the hooking members 145 and 343.

Contacts 390 held in blocks 340 and 310 of the base establish electrical contact by elastic pressure with the contacts males 190 contained in the insulators 130 of the plug.

Mass continuity is ensured by cruciform elements referenced 112, 116, 115 and 190 for the plug 100 and 350 for the base 300. The cruciform shields are kept in pressure contact at the level of their interface, that is to say at the level of their junction zones.

The assembly of a plug 200 as illustrated in FIGS. 11 to 14 with a base 400 as illustrated in FIG. 19 leads to a globally similar system which is distinguished only by non-continuity masses.

Those skilled in the art will understand that the present invention allows using common parts to quickly realize different types of connection, on the one hand by replacing conductive parts with insulating parts supplied in a kit, and secondly by having the associated wires correctly.

Of course, the present invention is not limited to the modes of particular achievements which have just been described, but extends to all variants according to his spirit.
