Description

The invention relates to connectors and connector adapters for multiple symmetrical signal transmissions. In particular, but not limited to, connectors and connector adapters are provided for connecting N symmetrical signal transmissions between N individual channels and a common channel.

There are currently various connectors for symmetrical signal transmission, in particular for differential data transmission (also known as “balanced data transmission”). The data signal is transmitted via pairs of conductors. These include connectors for the Ethernet described in the IEEE 802.3 series of standards.

Such a connector with up to N = 4 pairs of conductors is the connector known as RJ-45 or 8P8C, for example according to the series of standards “IEC 60603-7 -...” and / or “TIA-568A / B” and / or “ISO / IEC 11801 ... "and / or" Title 47 of the Code of Federal Regulations Part 68 ". With such a connector, for example in the structured cabling according to ISO / IEC 11801, a distinction is made between a fixed connector ("socket") and a free connector ("plug").

The conductor routing of the plug connection leads to crosstalk, i.e. a coupling of the N pairs of conductors to one another. The crosstalk limits the transmission properties of the connector. Therefore, for example, in the series of standards "IEC 60512-27 -..." and "Ansi / TIA A-568-C.2 -..." there are upper and lower limit values for near-end crosstalk attenuation "Or NEXT). The near-end crosstalk attenuation must therefore neither be too large nor too small.

Another connector type includes the connectors described in the "IEC 63171 -..." series of standards for symmetrical signal transmission via a single conductor pair (technically also "balanced single-pair data transmission"), in particular for single-pair Ethernet (SPE) . With these connectors, the differential data signal is only transmitted over one pair of conductors. No near-end crosstalk attenuation is therefore defined.

In many cases, data transmission links with RJ-45 connectors are installed. There is therefore an interest in using an existing infrastructure with a common channel for several symmetrical signal transmissions (for example by means of connectors of the RJ-45 type) for the transmission or continuation of symmetrical signal transmissions of individual channels (for example by means of connectors of the SPE type).

However, the lack of or indeterminate crosstalk attenuation in SPE cabling leads to indeterminate or impermissible transmission properties when the respective conductor pairs are connected directly. For example, the crosstalk attenuation resulting when connecting a connector of the type RJ-45 with N connectors of the type SPE can be impermissibly small for the connection using the RJ-45 or, for the use of individual SPE connections, the transmission through the crosstalk of the RJ-45 connection be disturbed.

The document US 2019/0238349 A1 describes an active converter to interconnect communication branches that meet different Ethernet standards on the physical layer and the data link layer. However, such an active converter requires a constant power supply. In addition, the active analysis and conversion of the signals is associated with a processing time that increases the latency of communication.

The invention is therefore based on the object of specifying a more energy-efficient connection for a plurality of symmetrical signal transmissions between, on the one hand, individual channels and, on the other hand, a common channel. An alternative or more specific task is to reduce the latency of a connection for several symmetrical signal transmissions between individual channels on the one hand and a common channel on the other.

The object or objects are achieved with the features of the independent claims. Appropriate configurations and advantageous developments of the invention are specified in the dependent claims.

According to the second aspect, the connector described can be permanently connected to the connection side and / or be designed as a free or fixed connector (for example of the RJ45 type) on the plug side.

A third aspect relates to a connector adapter for connecting N balanced signal transmissions between N individual channels and a common channel. The connector adapter comprises a first plug-in side that is mechanically connected or connectable to at least one first complementary plug-in connector and has 2 · N first plug-in contacts. In the connected state between the connector adapter and the at least one first complementary connector, the 2 · N first plug-in contacts are electrically connected to N symmetrical pairs of conductors which are each guided in one of the N individual channels. The connector adapter further comprises a second plug-in side that is mechanically connected or connectable to a second complementary plug-in connector and has 2 · N second plug-in contacts.

As an alternative or in addition, the connector adapter can each have a socket on the first and / or second plug-in side. The first and / or second complementary connector can be a plug.

In the connected state between the connector adapter and the at least one first complementary connector, the 2 · N first plug contacts can be electrically connected to the N symmetrical conductor pairs, which are each guided in one of the N individual channels, via complementary plug contacts of the at least one first complementary plug connector.

The 2 · N second plug contacts can be electrically connected in the connected state between the plug connector adapter and the second complementary plug connector via complementary plug contacts of the second complementary plug connector to the N symmetrical conductor pairs that are guided in the common channel.

The first plug side of the plug connector adapter can be mechanically connected or connectable to a first complementary plug connector, the first complementary plug connector having N pairs of plug contacts that are each electrically connected to another of the N symmetrical conductor pairs that are each guided in one of the N individual channels. Alternatively or additionally, the second plug-in side of the plug-in connector adapter can be mechanically connected or connectable to N complementary plug-in connectors, each of the N complementary plug-in connectors having a plug-in contact pair which is electrically connected to another of the N symmetrical conductor pairs, each in one of the N individual channels are led.

Each of the electrical connections can comprise a primary coupling of the coupling circuit between the 2 * N first plug contacts and the 2 * N second plug contacts. The adaptation of the crosstalk (for example near-end crosstalk) can comprise a cross coupling (also: secondary coupling) between the 2 · N first plug contacts and / or between the 2 · N second plug contacts and / or between the electrical connections.

According to the third aspect, the connector adapter can be designed as a detachable, stand-alone part. The connector adapter can also be referred to as an adapter or a plug-in adapter.

The plug-in side of the plug connector (or the first or second plug-in side of the adapter) can be mechanically detachably connected or connectable to the complementary plug connector. The connected state can also be referred to as the mated state. The complementary plug contacts of the complementary plug connector can be complementary to (for example each be plugged together with) the plug contacts of the connector (or the adapter).

In each aspect, the conductors and pairs of conductors can also be referred to as wires or pairs of wires. The coupling circuit can also be referred to as a compensation circuit. The near-end crosstalk can also be referred to as near-end crosstalk or, in technical terms, “Near End Cross Talk” (NEXT).

Since the coupling circuit adapts (for example, increases) the (for example, lower) crosstalk between the N symmetrical conductor pairs of the individual channels to the crosstalk between the N symmetrical conductor pairs of the common channel, embodiments of the connector can use an inhomogeneous cabling structure with individual channels (for example connections or Cables for single-pair Ethernet) and shared channels (e.g. connections or cables for Ethernet with 4 pairs of conductors) for symmetrical signal transmission.

The plug-in side (or the first plug-in side) can be arranged opposite the connection side (or the second plug-in side).

The connection side and the plug-in side (or the first plug-in side and the second plug-in side) can furthermore each comprise a shield contact and / or a grounding contact, which are preferably connected to one another in an electrically conductive manner (for example by means of the coupling circuit).

The connection of the N symmetrical signal transmissions between the common channel and the N individual channels can comprise a transmission or continuation of the N symmetrical signal transmissions.

In addition to the mechanical adaptation by means of the plug-in side or sides, exemplary embodiments of the plug connector or the plug-in connector adapter are also capable of adapting the electromagnetic parameters of the connections of the N symmetrical signal transmissions by means of the coupling circuit. Alternatively or in addition, the coupling circuit can adapt the crosstalk (for example the near-end crosstalk) between the N conductor pairs of the individual channels (for example SPE connectors and / or SPE conductor pairs) to the crosstalk between the conductor pairs in the common channel (for example in an RJ45 or 8P8C connector and / or in an Ethernet cable with 4 pairs of conductors).

Here, the generic term “channel” includes, for example, a cable (preferably with conductors within a common sheathing and / or shielding of the respective cable) or connections on a printed circuit board (also PCB connections), for example a local group of connections (preferably connections for an installation Connector).

For example, existing data transmission links are installed with RJ-45 connectors. Embodiments make it possible to use this infrastructure for the transmission or continuation of the symmetrical signal transmissions by means of connectors of the SPE type.

Exemplary embodiments of the plug connector or the plug connector adapter can be used for structured cabling and / or in automation technology (for example for a production process). Alternatively or in addition, embodiments of the connector or the connector adapter can be used in the field, i.e. for networking or data connection of field devices and / or in automation technology in an area outside of control cabinets or a control room.

Here, the term near-end crosstalk or near-end crosstalk attenuation (NEXT) can refer to crosstalk at a signal feed. For example, the connector and connector adapter can be arranged on the signal feed. For example, the connection side can be connected to a signal output (for example a network switch or switch).

Alternatively or in addition, the term near-end crosstalk or near-end crosstalk attenuation (NEXT) can refer to crosstalk in or on the connector or connector adapter. Insofar as the term near-end crosstalk or near-end crosstalk attenuation refers to the crosstalk in the vicinity of the connector or connector adapter, from the point of view of a signal feed remote from the connector or connector adapter, this crosstalk can also be or contribute to far-end crosstalk (FEXT).

The coupling circuit preferably comprises only passive components.

Embodiments of the connector or adapter can make it possible to use the N individual channels (for example 4 SPE cabling) for the common channel (for example an RJ-45 cabling) in that the coupling circuit can be designed to allow the To increase crosstalk between the conductor pairs routed in the N individual channels (for example the conductor pairs of the SPE cabling).

Conversely, to use an existing common channel (for example RJ-45 cabling) for the N individual channels (for example 4 SPE cabling), the crosstalk can be reduced. The distinction between an increase or decrease in the crosstalk can be dependent on the perspective or the signal direction through the connector or adapter.

Embodiments of the connector and / or the adapter can be combined, in particular can be plugged together. Alternatively or in addition, an embodiment of the connector can be combined with a conventional connector (as the complementary connector). Alternatively or additionally, an embodiment of the adapter can be combined with a first conventional connector (as the first complementary connector) and / or with a second conventional connector (as the second complementary connector). Such combinations are also referred to below as an overall system.

The adaptation of the crosstalk according to one of the aspects can include or effect a compensation of the crosstalk by means of the coupling circuit (also: compensation circuit). For example, in relation to the overall system (e.g. a conventional RJ-45 socket combined with an exemplary embodiment of the adapter according to the third aspect), a compensation of the crosstalk can be achieved, i.e. the crosstalk of the overall system can be reduced.

Embodiments of the connector according to the first or second aspect and / or embodiments of the adapter according to the third aspect and / or conventional connectors are collectively referred to as components. The overall system can comprise at least two components, at least one of the at least two components being designed according to one of the three aspects.

The individual components each have physically separate compensation circuits, whereby the compensation circuit of a component, which is the embodiment of the connector or adapter, can be designed to adapt the crosstalk of the separate channels to the crosstalk in the common channel (preferably according to one of the three aspects). The compensation of the crosstalk in the overall system can thus comprise two physically separate compensation circuits.

For example, the overall system comprises a first compensation circuit which can be integrated in the conventional component (i.e. in the conventional connector, for example in an RJ-45 socket, and / or in a cabling of the conventional connector). If such a conventional connector is combined with an embodiment of the connector or the adapter according to one of the aspects (for example if an adapter according to the third aspect is built into an existing cabling), the coupling circuit of the embodiment of the connector or adapter according to one of the aspects functions as the second Compensation circuit, so that the crosstalk in the overall system with the first and second compensation circuit is reduced. The signals pass through both compensation circuits regardless of their direction.

For example, a mated connection between an RJ-45 socket as the second complementary connector and an RJ-45 plug as the second connector of an embodiment of the adapter with SPE connector or SPE socket as the first connector to improve (ie reduce) the Conduct overall crosstalk. For example, by compensating for both the crosstalk of the 4 SPE conductor pairs and the crosstalk of the 4 RJ-45 conductor pairs, the coupling circuit can adapt the crosstalk between the N symmetrical conductor pairs routed in the individual channels to crosstalk between the N symmetrical conductor pairs routed in the common channel Pairs of conductors.

The cross coupling brought about by the coupling circuit can be implemented as follows. The effect of the coupling circuit of the adapter according to the third aspect for the signal direction of the N symmetrical signal transmissions from the common channel (for example an RJ-45 cabling) via the adapter to the N individual channels (for example N SPE cabling).

The N symmetrically transmitted signals coming from the common channel (for example a cable) first reach the conventional compensation circuit of the conventional connector (for example an RJ-45 socket). The conventional compensation circuit of the conventional connector is designed to cause fictitious crosstalk with the voltage -x V. The signals disturbed by the amount -x V run through the plug contacts of the conventional connector (for example the RJ-45 socket) in an embodiment of the adapter, for example a so-called SPE adapter, the second plug-in side is designed as an RJ-45 plug and the first plug-in side has SPE plugs or SPE sockets. In the exemplary embodiment of the adapter, the coupling circuit (for example a compensation circuit) of the adapter causes a fictitious crosstalk of + x V. The signals that are now fed into the SPE cabling from the adapter on the first plug-in side correspond approximately or ideally correspond to the signals, which was in the common channel (e.g. in the common cable) before the conventional compensation circuit of the conventional connector (for example, before the compensation circuit of the RJ-45 socket).

In the opposite signal direction (for example from SPE cabling to RJ45 cabling) the SPE adapter can initially cause fictitious crosstalk of + x V, which is compensated by the RJ-45 socket (-x V).

For each exemplary embodiment (for example the connector and / or the adapter, e.g. only for the SPE adapter), the crosstalk can be precisely adapted during development. The compensation circuit (for example an arrangement of passive components) can shift the crosstalk of the individual components in both directions, i.e. the crosstalk can be increased or decreased.

In any aspect, the coupling circuit can have a cross coupling. The cross coupling can electromagnetically couple the electrical connections and / or the N symmetrical conductor pairs routed in the common channel and / or the N symmetrical conductor pairs routed in the individual channels in order to adapt (preferably to compensate) the crosstalk (for example, the near-end crosstalk). As an alternative or in addition, the cross coupling can adapt a (near) crosstalk attenuation between the N symmetrical conductor pairs routed in the individual channels (preferably by compensating) to a (near) crosstalk attenuation between the N symmetrical conductor pairs routed in the common channel.

As an alternative or in addition, the cross coupling can cause (near) crosstalk attenuation between the N symmetrical conductor pairs routed in the individual channels, which is greater than a lower limit value and / or which is less than an upper limit value. The lower and / or upper limit value can be predetermined for the (near) crosstalk attenuation between the N symmetrical conductor pairs routed in the common channel, optionally in accordance with the IEC 60512-27 series of standards of the International Electrotechnical Commission (IEC) and / or in accordance with the A series of standards -568-C.2 of the Electronic Industries Alliance (EIA) and / or the Telecommunications Industry Association (TIA).

The cross coupling can be a secondary electromagnetic connection (also: secondary coupling) compared to the electrical connections (also: primary electrical connections or primary coupling). For example, an impedance (preferably an active component or real component of the impedance) of the secondary electromagnetic connection can be greater than an impedance (preferably an active component or real component of the impedance) of the primary electrical connection.

The coupling circuit can have a capacitive and / or inductive cross coupling between the electrical connections and / or the N symmetrical conductor pairs routed in the common channel and / or the N symmetrical conductor pairs routed in each case in the individual channels. The coupling circuit can have a capacitive and / or inductive cross coupling which is designed to electrically couple the electrical connections and / or the N symmetrical conductor pairs routed in the common channel and / or the N symmetrical conductor pairs routed in the individual channels.

The capacitive and / or inductive cross-coupling of the N symmetrical conductor pairs routed in one of the N individual channels can also be referred to as a parallel connection of the respective capacitance and / or inductance.

The cross coupling can include and / or be effected by means of at least one discrete component, preferably a capacitor, a coil or an oscillating circuit. Alternatively or additionally, the cross coupling can comprise and / or be effected by means of a relative and / or geometrical arrangement of the electrical connections and / or a relative and / or geometrical conductor routing of the electrical connections. Alternatively or additionally, the cross coupling can comprise and / or be effected by means of an arrangement of shield potentials and / or floating structures and / or dielectric structures between the electrical connections.

Each of the N individual channels can each comprise a single cable. As an alternative or in addition, the N symmetrical conductor pairs routed in the N individual channels can each be routed in a single cable. The N symmetrical conductor pairs can be twisted around one another in the respective individual cable.

The common channel can comprise a common cable. As an alternative or in addition, the N symmetrical conductor pairs routed in the common channel can each be routed in a common cable. In the common cable, the N symmetrical conductor pairs can each be twisted around one another, optionally with the N symmetrical conductor pairs being twisted with different lay lengths and / or twisted with different directions of rotation.

The twisting (or twisting) can be implemented in the respective cable by stranding (or stranding).

The connection side of the plug connector or the complementary plug contacts of the complementary plug connector can also be connected to a circuit board (for example a circuit board or a printed circuit, also: PCB) instead of cables.

Each of the N individual channels can each comprise a single connection of a circuit board. As an alternative or in addition, the N symmetrical conductor pairs routed in the N individual channels can each be routed in a single connection of a circuit board.

The individual connections of the circuit board can be spaced from one another. For example, a distance between the individual connections of the circuit board can be greater than a distance between connection contacts (for example connection surfaces) of one of the individual connections of the circuit board for connecting one of the symmetrical conductor pairs.

The common channel can comprise a common connection of a printed circuit board. The N symmetrical conductor pairs routed in the common channel can each be routed in a common connection of a circuit board.

The common connection of the printed circuit board can comprise 2 * N connection contacts (for example connection surfaces), with adjacent connection contacts having a uniform spacing. For example, the same spacing can exist between adjacent connection contacts for connecting lines of different conductor pairs as between adjacent connection contacts for connecting lines of the same conductor pair.

The number of N pairs of conductors (for example in the common channel) and / or the number of N individual channels can be 4.

The plug-in side of the connector that is connected to the N individual channels or the first plug-in side of the connector adapter can correspond to a plug or socket for single-pair Ethernet (SPE), optionally in accordance with the IEC 63171 series of standards The plug-in side of the connector connected to the common channel or the second plug-in side of the connector adapter correspond to a plug or a socket according to the Registered Jack 45 (RJ-45) connector or a modular connection with 8 positions for 8 contacts (8P8C).

The electrical connections can have two electrical connections for each of the N line pairs. The electrical connections preferably comprise a galvanic connection.

At least one or each of the electrical connections can have a capacitive coupling or an inductive coupling or a combination of a capacitive and inductive coupling. The capacitive and / or inductive coupling in the electrical connections between the connection contacts and the plug contacts or between the first and second plug contacts can also be referred to as a series connection of the respective capacitance and / or inductance.

The pairs of conductors that belong together (e.g. an SPE pair on an RJ45 pair) are electrically (preferably galvanically) connected. The compensation between different pairs of conductors is based on electromagnetic coupling (i.e. cross coupling).

The N symmetrical conductor pairs routed in the common channel can be arranged within a common shield.

The coupling circuit can comprise at least one two-port. A first port of the two-port can be connected to the electrical connections of a first conductor pair of the N symmetrical conductor pairs. A second port of the two-port can be connected to the electrical connections of one of the first, different second conductor pair of the N symmetrical conductor pairs. For example, the coupling circuit may comprise N * (N + 1) / 2 two-port, which couples the electrical connections of each of the N symmetrical conductor pairs with the electrical connections in each case of another of the N symmetrical conductor pairs.

The invention is explained in more detail below with reference to the accompanying drawings using preferred exemplary embodiments, which can optionally be combined with one another.
