Abstract

(57) Abstract: A connector is composed of a plug and an outlet, which, when combined, define four shielded quadrants. Each quadrant contains a pair of contacts. The shield members in the plug overlap and the shield members in the outlet overlap. Further, the shield members in the outlet, when combined, overlap adjacent shield members in the plug. When the shield members overlap each other when the shield members are joined, the shield is improved and the crosstalk is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD [0001] The present invention relates generally to telecommunication connectors, and more particularly, to telecommunication plugs and outlets with improved performance characteristics.

BACKGROUND OF THE INVENTION With improvements in telecommunications systems, voice and / or
Alternatively, a data signal can be transmitted. Several industry standards have been established that specify the combined performance level of twisted pair cabling components. For many, the main criteria that are considered to be international benchmarks for commercial telecommunications components and mounting are the standard ANSI / TIA / ELA-568-A (/ 56
8) Commercial Building Telecommunications Cabling Standard and 150 / IEC 11801 (/ 11801), a generic cabling for customer premises. For example, category 3, 4, 5 cables and connecting hardware are described in both / 568 and / 11801, and in other national and regional specifications. These specifications specify that transmission requirements for Category 3 components are up to 16 MHz. Transmission requirements for Category 4 components are specified up to 20 MHz. Transmission requirements for Category 5 components are specified up to 100 MHz. New standards are continually being developed, and future standards will require transmission requirements of at least 600 MHz. Achieving such transmission speeds requires a completely shielded twisted pair cable, where each pair has its own foil.
Or wrapped in a screen. In addition, all pairs are wrapped together by a single foil or screen.

[0003] The transmission requirements described above also specify restrictions on near-end crosstalk (NEXT). Telecommunications connectors are configured in sets of pairs and are typically formed of tip and ring connectors. As telecommunications connectors are miniaturized, adjacent pairs are placed closer together and crosstalk occurs between adjacent pairs. Various techniques are used in the art to meet near-end crosstalk requirements.

US Pat. No. 5,593,311 discloses a shielded compact data connector designed to reduce crosstalk between contacts of the connector. A pair of contacts are located in a metal channel. When the connectors are connected, the channels contact each other and each pair is encapsulated in a metal shield. One disadvantage of the design in U.S. Pat. No. 5,593,311 is that the metal channels are connected in a butt connection, one surface touches an adjacent surface, and there is no overlap. Since all parts contain some manufacturing tolerances, there may be air gaps between the shields, which reduces the shielding effectiveness. Another disadvantage is that the stripped wires are exposed to each other behind the connector,
For this reason, crosstalk may occur. Thus, there is a need in the art for a connector with improved pair shielding.

SUMMARY OF THE INVENTION The above-mentioned deficiencies and other disadvantages and deficiencies of the prior art are overcome or at least alleviated by the high performance telecommunications connector of the present invention. In one embodiment, the connector is formed of a plug and an outlet, which, when combined, define four shielded quadrants, each of which contains a pair of contacts. In another embodiment, the connector is formed of a plug and an outlet, which, when combined, define two shielded quadrants, each of which contains a pair of contacts. In yet another embodiment of the present invention, a printed circuit board (PCB) connector is provided, the connector being formed of a plug and an outlet, which, when combined,
Four shielded quadrants are defined, each of which contains a pair of contacts. In this embodiment, the connect is particularly suitable for being mounted on a circuit board. In yet another embodiment of the present invention, there is provided an improved plug top cover having a metal latch (latch) sub-assembly (sub-assembly) which allows the cable from the plug cable screen to the outlet cable screen to be extended. A direct electrical path is possible. In all of the embodiments described herein, the improved connector of the present invention is shown, wherein the shield members in the plug overlap and the shield members in the outlet overlap. Further, the shield members in the outlet, when combined, overlap adjacent shield members on the plug. When the shield members overlap at the junction of the shield members, the shield is improved and crosstalk is reduced.

[0006] The above and other features and advantages of the present invention will be appreciated and understood by those skilled in the art from the following detailed description and drawings.

The drawings will be described. In the drawings, similar elements are denoted by similar reference numerals.

Each contact 160 has a generally planar body 180, a contact end 182, and a termination 183. The terminations include insulation displacement contacts 184 that penetrate the insulation of the individual wires in cable 10;
This forms an electrical contact with the wire, as is well known in the art.
For the attachment of the wires into the insulation displacement contacts 184, see FIG.
This will be described with reference to FIGS. Each insulation displacement contact is at an angle of 45 ° to the long axis of body 180. As shown in FIG. 1, the plug 100 includes four contact carriers 108, each having a pair of contacts 160,
It has a total of eight contacts.

FIG. 6 is an exploded perspective view of the plug 100 including the end cap 186. A termination cap 186 is provided for each pair of contacts 160. As is well known in the art, the termination cap places the wire over the insulated displacement contact, penetrates the insulation, and electrically connects the wire to the insulated displacement contact. Termination cap 186 includes a first lip 188 and a second lip 190 spanning ledges 149, 147 on plug core 106. First lip 188 and second lip 1

6 from being removed.

FIG. 7 is another exploded perspective view of the plug 100. As shown in FIG.
Each end cap 186 is located in a first position thanks to a first lip 188 and a second lip 190 that span the first ledge 149. Boot 112 includes a circular lip 113 that mates with a groove 129 formed in top cover 102 and bottom cover 104. A slot 115 may be formed through the boot 122 and perpendicular to the lip 113 such that the lip 113
12 expands during installation, reducing the force required to install and remove the boot.

The attachment of the wire into the plug 100 will be described with reference to FIGS. As shown in FIG. 8, the cable 10 includes eight wires 198. Each pair of wires 198 is wrapped by a wire pair shield 200. The ground layer 196 is also housed within the cable 10 and is pulled back on the outer jacket of the cable 10. Wire 198 is inserted into wire opening 194 in termination cap 186. As described above, each wire opening 194 is connected to the insulation displacement contact 18.
4 and thus each wire is located above the insulating displacement contact 184. It is understood that the boot 112 is placed on the cable 10 before inserting the wire 198 into the termination cap 186. FIG. 9 is a diagram illustrating the wire 198 disposed in the wire opening 194. Once the wires are in the end cap 18
6, a force is applied to each end cap 186 toward the plug core 106 in the direction indicated by the arrow in FIG. Using a one-handed tool, force can be applied to all four end caps 186 simultaneously, facilitating installation.

FIG. 10 shows the end cap 186 in a second position. First lip 188 and second lip 190 straddle second ledge 147 and end cap 186 is held in a second position. In this state, the wire 198 disposed in the wire opening 194 is pushed onto the insulating displacement contact 184. As is well known in the art, the insulating displacement contacts 184 separate the insulation on each wire 198, thereby forming an electrical contact between the wire 198 and the contact 160. An important aspect of the present invention, shown in FIG. The length of the first planar shield 132 and the second planar shield 134 is such that a portion of the first planar shield 132 and a portion of the second planar shield extend beyond the backside of each termination cap 186 to provide a buffer zone 206. Is to be established. Each wire pair resides in buffer region 206. The buffer area 206 is important. I mean,
This is because, during installation, the wire pair shield 200 is removed and individual wires can be inserted into the wire openings 194. Even assuming that the installer has removed the recommended exact length wire pair shield 200, a small amount of exposed wire will cause crosstalk between adjacent pairs at frequencies above 600MHz. In a non-ideal installation, the installer would remove too many wire pair shields 200. Thus, buffer zone 206 reduces crosstalk in ideal or non-ideal mounting and improves connector performance. The buffer zone should have a length, measured from the back of the end cap 186, greater than the length of the exposed wire 198 (removed wire pair shield) in the worst case installation.

The next step of the mounting process is to mount the top cover 102 and the bottom cover 104 on the plug core 106 as shown in FIG. Each of the top cover 102 and the bottom cover 104 has a projection 202, which engages with a recess 204 having the same shape on the plug core 106, and the top cover 102 and the bottom cover 104 are fixed to the plug core 106. Furthermore, the top cover latch 1
28 meshes with the bottom cover opening 130, and the top cover 102
04. A barb 168 on the shield contact 164 passes through the ground layer 196 and the cable jacket, and the shield connector 164 connects the cable 1
0 is mechanically and electrically connected. The final step in plug assembly is a step of fixing the boot 112 to the plug. As shown in FIG.
Snaps onto the top and bottom covers. A lip 113 on the inner surface of the boot 112 meshes with a groove 129 formed in the top cover 102 and the bottom cover 104.

FIG. 12A is a perspective view of a plug according to another embodiment. As shown in FIG. 12A, the boot 112 includes two L-shaped channels 197, which house columns 124 formed on the top cover 102 and columns 126 formed on the bottom cover (FIG. 12B). I do.

In one plane at an oblique angle with respect to the front face 317. When placed in the faceplate, this directs the outlet to the ground, providing a gravity feed design. Gravity feed reduces the bend angle of the cable connected to the plug 100 and reduces the likelihood that the cable will bend beyond its minimum bend radius, causing signal degradation or loss. Alternatively, notches 314, 315 may be in one plane parallel to front surface 317 of outlet 300. The member 316 includes the elastic arm 31

16 includes a shield contact 560, wherein the shield contact
Fourteen ground planes are electrically connected to the outlet core of outlet 700. The shield contact 560 is conductive and is preferably made of metal. Shield contact 560 has an arcuate portion 562 formed to generally conform to the shape of cable 514. The arcuate portion 562 includes a barb 564 that extends through the ground plane of the cable 514 and the cable jacket. As a result, the shield contact 560 is electrically and mechanically connected to the cable 514. When the latch 516 is mated with the top cover 502, the arcuate portion 562 mates with the neck 573 below the top cover 502. When assembled, the arcuate portion 560 is positioned inside the plug 500 and the rest of the latch 516 is positioned outside the plug 500.

FIG. 36B is an exploded perspective view of the plug 500 including the end cap 558. Termination caps are provided for each pair of contacts. As is well known in the art,
The termination cap places the wire over the insulating displacement contact and penetrates the insulator, and the wire and the insulating displacement contact are electrically connected. The end cap 558 is connected to the first
Lip 600 and a second lip 602 that span the ledges 554, 556 on the plug core 506. First lip 600 and second lip 602
Has an oblique surface, and the first ledge 556 and the second ledge 554 also have an oblique surface, which facilitates the installation of the end cap 558, as described below. Each termination cap 558 also includes a contact opening 604 for receiving an insulating displacement contact 184 (see FIG. 5) and a pair of wire openings 606 for receiving wires from cable 514. Wire opening 606 is aligned with insulation displacement contact 184 (FIG. 5). The plug of FIG. 36B is shown as received by the customer. An end cap 558 is disposed within the plug core 506 and the first
It is held at the position. The first lip 600 is located on the first ledge 556,
Termination cap 558 is held in the first position, and second lip 602 is located directly below first ledge 556 so that termination cap 558 is not accidentally removed from plug core 506.

FIG. 37 is another exploded perspective view of the plug 500. As shown in FIG. 37, each end cap 558 has a first lip 60 that spans a first ledge 556.
It is in the first position thanks to the zero and the second lip 602. Boot 512 includes a circular lip 513 that mates with a groove 526 in top cover 502 and bottom cover 504.

The attachment of the wire to the plug 500 will be described with reference to FIGS. As shown in FIG. 38, the cable 514 includes four wires 608. Each pair of wires 608 is wrapped in a wire pair shield 610. The ground layer 612 is also housed within the cable 514 and is pulled back on the outer jacket of the cable 514. Wire 608 extends through wire opening 60 in termination cap 558.
6 is inserted. As described above, each wire opening 606 is aligned with an insulating displacement contact 184, and thus each wire is positioned above the insulating displacement contact 184 (see FIG. 5). It is understood that the boot 512 is placed on the cable 514 before inserting the wire into the termination cap 558. FIG. 9 is a diagram illustrating the wire 198 disposed in the wire opening 194. Once the wires are placed in the termination caps 558, a plug core 506 is attached to each termination cap.
, A force is applied in the direction indicated by the arrow in FIG. Using a one-handed tool, force can be applied to all four end caps 558 simultaneously, facilitating installation.

FIG. 39 shows the end cap 558 in a second position. First lip 600 and second lip 602 straddle second ledge 554, and end cap 558 is held in a second position. In this state, the wire 608 disposed in the wire opening 606 is pushed onto the insulating displacement contact 184. As is well known in the art, the insulating displacement contacts 184 separate the insulation on each wire 608, thereby forming an electrical contact between the wire 608 and the contact 160. An important aspect of the invention shown in FIG. 39 is the use of a buffer zone 614. The length of the plane shield 532 extends beyond the back surface of each end cap 558 and establishes a buffer zone 206. Each wire pair resides in the buffer region 614. The buffer zone 614 is important. This is because, during installation, the wire pair shield 200 is removed and individual wires can be inserted into the wire openings 606. The installer must ensure that the recommended length wire pair shield 61 is used.
Even assuming zero removal, a small amount of exposed wire will cause crosstalk between adjacent pairs at frequencies above 600 MHz. In a non-ideal installation, the installer would remove too many wire pair shields 610. in this way,
The buffer zone 614 reduces crosstalk in ideal or non-ideal mounting and improves connector performance. The buffer zone 614 is provided with the end cap 55
8 exposed at the worst case installation, as measured from the back of
(Removed wire pair shield).

The next step of the mounting process is a step of mounting the top cover 102 and the bottom cover 104 on the plug core 506 as shown in FIG. The top cover 502 and the bottom cover 504 each have a projection 582, which engages with a similarly shaped recess 584 on the plug core 506, and the top cover 102 and the bottom cover 104 are fixed to the plug core 106. Further, the top cover latch 528 engages with the bottom cover opening 530, and the top cover 502 is fixed to the bottom cover 504. The latch 516 is secured to the top cover 502 by aligning the pawl 570 with the first receiving opening 566 and slidingly engaging the neck 571 with the slot 567. The slot 567 is connected integrally with the first accommodation opening 566. During the engagement of the latch 516 with the top cover 502, the post 572 is received in the second receiving opening 568, whereby the neck 574 of the post 572 slides into engagement with the slot 569. The latch 516 shown in FIG. 40 is in a first position, in which the latch body 518 includes a latch 516 made of a resilient material.
This allows the neck 571 to contact the head portion 576 of the post 572 by mating with the slot 567. The shield contact 560 of the latch 516 is located below the neck 616 of the top cover 502 so that the shield contact 5
60 engages with cable 514. Barb 564 on shield contact 560
Penetrates through the ground layer 612 and the cable jacket, and
0 is mechanically and electrically connected to the cable 514. The final step in plug assembly is a step of fixing the boot 512 to the plug 500. As shown in FIG. 41, the boot 512 snaps onto the top cover and the bottom cover. The lip 113 on the inner surface of the boot 512 meshes with the groove 526 formed in the top cover 502 and the bottom cover 504.

FIG. 42 is a perspective view of the assembled outlet of the first alternative embodiment, shown generally as 700. Outlet 700 is used with plug 500. The outlet 700 is such that the second plane shield 336 is
Same as outlet 300 except that it has been replaced with 32. The outlet 700 includes a top cover 702, a bottom cover 704, and a core 706. The top cover 702, the bottom cover 704, and the core 706 are all conductive,
Provide a shield as described herein. These conductive components may be made of metal, metallized plastic, or other well-known conductive materials.
Core 706 supports insulating contact carrier 708. Each contact carrier includes a contact 710. Optionally, a door 311 is also provided to prevent contaminants (eg, dust) from entering outlet 700.

The top cover 702 includes a pair of resilient arms 712 having a notch 714 formed therein. The notch 714 accommodates the edge of the faceplate as described with reference to FIG. Another notch 715 is formed at the bottom of the outlet core 706,
Accommodates other edges of faceplate. The notches 714, 715 are in one plane at an oblique angle to the front face 717 of the outlet 700. When mounted in the faceplate, this points the outlet to the ground and provides a gravity feed design. Gravity feed reduces the bend angle of the cable connected to the plug 500 and reduces the likelihood that the cable will bend beyond its minimum bend radius, causing signal degradation or loss. Alternatively, notches 714, 715 may be in a plane parallel to front surface 717 of outlet 700. The member 716 is connected to the end of the elastic arm 714,
The front surface includes a recess 718. Recess 718 houses one edge of identification icon 724 (see FIG. 43). The identification icon 724 is located on the support surface 720,
It engages with the recess 722. Both support surface 720 and recess 722 are formed on outlet core 306.

Each half is designed to accommodate the two pair plug 500 of FIG. The side wall 726 and the vertical shield 732 include a rib 736 for engaging with the recess 550 in the plane shield 532 to form an overlapping shield member.

An important feature of outlet 700 is that opening 740 in outlet core 706
Is the formation of Opening 740 is designed to receive latch extension 524 of plug 500 and serves to secure plug 500 to outlet 700.
The latch extension 524 is guided into the opening 740 and the underside of the top wall 728 of the outlet core 706 is lip 1200 (FIG. 59) for engaging the opening 568 in the latch extension 524 as shown in FIG. )including. Latch extension 524 is open 7
Once inserted into the lip, the lip slope 1202 causes the latch extension 524 to slide and engage the outlet core 706 by securing the latch extension 524 to the shoulder 1204 of the lip 1200. When the latch 516 is pushed toward the top cover 502 to release the plug 500, the opening 568 is disengaged from the lip 1200. Similar to the outlet 300 of FIG. 13, the top cover 702, bottom cover 704, and core 706 of the outlet 700 have overlapping joints to provide better isolation and shielding of the contact pair, and therefore, lower performance. improves.

FIG. 43 illustrates the two plugs 500 of FIG.
It is a perspective view of. In FIG. 43, the outlet 700 is placed in the face plate 800. The opening of the outlet 700 is at an angle to the face plate. This angle is
It is established by a notch 714 on the outlet top cover 702 and a notch 715 on the outlet core 706, which are in one plane at an oblique angle to the outlet face 717. As described above, this forms a gravity feed orientation in which the cable connected to the plug associated with outlet 700 is bent toward the floor, thereby reducing bending on the cable. This reduces the likelihood that the cable will bend less than the minimum bend radius. Identification icon 724 also functions as a lock that secures outlet 700 within faceplate 800. To mount outlet 700 in faceplate 400, resilient arm 712 is deflected until both notch 714 and notch 715 align with the edge of the faceplate opening. At this point, arm 712 returns to its original position. Identification icon 72
When 4 is positioned in recess 718 and recess 722, this prevents arm 712 from deflecting toward outlet core 706, thus securing outlet 700 in place in faceplate 800. In this embodiment, a two-pair plug 500 is used in the outlet 700 and occupies the same space as when one four-pair plug 100 is used in the outlet 300. Conveniently, a user may choose to insert one or two plugs 500 into outlet 700 without having to consider whether additional space is required for installation.
