Definitions

  • the invention relates to a method and a cable manager for multi-core cables for positioning wires in a connector.
  • An electrical plug connection is generally formed by a socket and a plug, the distinction being fluid in some novel electrical plug connections.
  • plug and socket will continue to be used for a better understanding.
  • crosstalk between the contact pairs occurs in particular in the contact area, where the plug and socket are electrically connected to one another.
  • the contact pairs can be arranged very far apart or a shield can be arranged between the contact pairs.
  • the contact pairs have to be arranged very close to one another in terms of design, the measures described above cannot be carried out, and crosstalk must be compensated for.
  • R J-45 connector The most widespread electrical connector for symmetrical data cables is the R J-45 connector, which is known in various embodiments depending on the technical requirements.
  • Known Category 5 R J-45 connectors have, for example, crosstalk attenuation of> 40 dB at 100 MHz transmission frequency between all four contact pairs. Due to the unfavorable contact assignment on the RJ-45, there is increased crosstalk due to the design, particularly with the connector between the two pairs 3,6 and 4,5 due to their nested arrangement. For reasons of compatibility, however, the contact assignment cannot be changed. Crosstalk is therefore compensated for, for example, by crossing the contacts in the socket. It has also been proposed to integrate additional compensation measures into the connector.
  • a plug comprises a connection area where the wires of the cable are connected to the contacts of the plug, and a contact area where the contacts of the plug are connected to the contacts of the socket.
  • the area of the plug where the untwisted wires of the cable are routed is called the cable manager and the part that carries the contacts is called the center.
  • the center is formed in the connection area with through-ring connections, which produce the insulation of the wires and an electrical contact to the wires.
  • the untwisted cable wires in and in front of the cable manager result in additional crosstalk, whereby in particular the crosstalk can fluctuate in a wide range due to the untwisting in front of the cable manager, depending on how much the wire pairs are untwisted during assembly. Compensation is correspondingly difficult to determine.
  • the invention is therefore based on the technical problem of creating a method and a cable manager by means of which repeatable electrical parameters can be set during the connection process.
  • the cable manager comprises two manager halves which are connected to one another in an articulated or hinge-like manner, each manager half having at least one longitudinally extending channel which is in a front region is formed with a centrally arranged separating element and has slot-shaped openings on the underside.
  • a pair of wires can be guided in the twisted state in the channel from the articulated or hinged rear part to the front area.
  • the twisted pair of wires is then untwisted on the separating element and the wires are clamped between the separating element and the channel wall.
  • a penetration connection can then contact the wires through the slot-shaped openings.
  • the cable manager with the slot-shaped openings is adjusted to the penetration connections and the two manager halves are adjusted using a force moving towards each other. Due to the articulated or hinge-like connection, the two manager halves are adjusted to each other so that all wires are contacted evenly and safely.
  • the position and thus the distance between the wires is precisely defined via the separating element, as a result of which the crosstalk generated is also precisely defined and predeterminable.
  • the same effect can be achieved in that the cable manager is rigid and the center carrying the contacts is designed to be partially movable in some way. It is crucial that the cores are arranged in a well-defined position in relation to one another in the area of the separating element. Further advantageous embodiments of the invention result from the subclaims.
  • the two manager halves are of identical design, so that, for example, only one injection mold is required for production using injection molding technology. Furthermore, this simplifies assembly, since there is no need to pay attention to different parts.
  • the cable manager is preferably formed in the front area with latching means which establish a connection with corresponding latching means of a center carrying the contacts.
  • the channel in the front area of the separating element is open. After assembly, the channel is then closed by a clamp that can be snapped onto the manager half.
  • the channels in the area up to the clamping rib can be metallized on the inside, which has the effect of shielding.
  • FIG. 1 is a first perspective view of a cable manager
  • 2 shows a second perspective view of the cable manager
  • FIG. 3 shows a perspective bottom view of a clamp
  • FIG. 4 shows a perspective top view of the clamp
  • FIG. 5 shows an exploded view of a plug.
  • the cable manager 1 for a four-pair cable comprises two manager halves 2, 3, which are completely identical.
  • the manager half 2, 3 is formed on one side with a receptacle 4 acting as a bearing and on the other side with a web 5 which fits into the receptacle 4.
  • the manager halves 2, 3 are each formed with two channels 6, which extend over the full length of the manager halves 2, 3.
  • the channels 6 are closed in the rear area by a plate 7 and are otherwise open at the top.
  • the side edges of the channels 6 are formed with U-shaped recesses 8.
  • a separating element 9, which is designed as a rib and extends over the length of the recess 8, is arranged in the center of the channel bottom.
  • each manager half 2, 3 has a continuous, rectangular latching opening 10.
  • the channel 6 has a slot-shaped opening 11.
  • a pair of wires that belong together is untwisted.
  • the wires are positioned with their insulation at the positions provided for them on the left or right of the separating element 9 and clamped between the separating element 9 and the channel wall.
  • a clamp 12 according to FIGS. 3 and 4 is then snapped onto the front area of the manager halves 2, 3 to fix the cores.
  • the clamp 12 has U-shaped catches 13 on its underside, which are guided into the recesses 8 of the manager halves 2, 3 and then latch with the catches 26 of the center 22.
  • the clamp 12 is each formed with two half-shells 14, which are connected to one another via a common ridge 15.
  • the clamp 12 has a latch opening 16 which is congruent with the latch opening 10 of the manager halves 2, 3.
  • Two locking bevels 18 are arranged laterally on the walls 17 delimiting the locking opening 16, that create a mechanically intimate connection in the middle between manager halves 2, 3 and clamp 12.
  • the clamp 12 is formed with cuboid elevations 19 which come to rest on corresponding contact surfaces in front of and behind the latch opening 10 of the manager halves 2, 3.
  • the clamp 12 is formed with rectangular locking receptacles 20, which are used for locking with the center carrying the contacts.
  • the cable manager 1 is locked in place with the center 22.
  • the center 22 is formed with a guide 23 and a detent 24 on the top and bottom.
  • the contacts arranged on the center 22 are designed as penetrating connections in the area of the latching lug 24.
  • the cable manager 1 is then pushed onto the center 22 so that the latching openings 10, 16 lie on the latching lug 24. If the front area of the two manager halves 2, 3 is now pressed towards one another, the center 22 and the cable manager 1 lock together at different points.
  • the fork-shaped elements 25 engage above and below the articulated connection on the cable manager 1. Additional locking lugs 26 engage in the recesses 20 of the clamp 12. When locked, the penetrating connections push through the slot-shaped openings 11, cut through the insulation and contact the wires.
  • the cable manager can be used for both round and flat cables as well as for shielded and unshielded cables.
