Description

Electrical plug connection

BACKGROUND OF THE INVENTION

1. Field of the invention

The invention relates to an electrical plug connection, in particular between two vehicle parts. More particularly, the invention relates to a connector for transmitting data.

2. Description of the Related Art

In rail vehicle technology so-called electrical contact couplings are used for the transmission of signals or power transmission between two adjacent car bodies of a multi-unit vehicle, such as a train. The arrangement and size of the electrical contact couplings used are dependent on the available space on the vehicle, the number of signals to be transmitted and the requirements of the car manufacturer or the railway operator. In such an electrical contact coupling plug connections are usually provided for to be continued by a tension member to an adjacent tension member lines. When coupling two tension members, the electrical contact couplings attached to the tension member are moved toward one another and aligned with one another such that the connectors mesh with one another and contact each other electrically. When transmitting electrical signals via the plug-in connections, an increase in the transmission rates and the amount of data to be transmitted is expected in the future. It is already common today, in addition to the pure control signals and a vehicle bus or signals for consumer electronics to conduct over the connectors. It uses data bus connectors that achieve data rates of up to 1 Gbit / s. At higher data rates over 1 Gbit / s, however, the signal quality of the data bus connectors on the market deteriorates so much that no practicable signal transmission is possible.

SUMMARY OF THE INVENTION

An object of the invention is to provide an improved technique for transmitting electrical signals, in particular between two train parts which can be coupled together.

This object is achieved by a plug connection and a coupling device according to the features of the independent claims. Preferred embodiments of the invention are specified in the dependent claims. A connector for transmitting electrical signals comprises a housing; an insulator to be arranged within the housing with a plurality of internal, mutually insulated conductors, wherein the insulator comprises a Isolierkörpervorderteil and a Isolierkörperhinterteil, wherein the Isolierkörpervorderteil with a Isolierkörpervorderteil another plug connection is mechanically connectable, and wherein the conductors are electrically connectable to the insulator rear part to a cable. The conductors between the Isolierkörperhinterteil and the Isolierkörpervorderteil each form a releasable electrical connection.

The connector can be set up for mechanical and / or electrical connection with another, identical or complementary connector. The insulating body can mechanically fix the conductors individually and electrically insulate them from one another. For example, the insulating body can be produced from a plastic, for example in casting or injection molding technology. In particular, when the plug-in connection between two tension members is used, the insulating body on the side, which is adapted to engage with the other connector, an increased mechanical wear by connection or release operations, or, if no other plug-in connection is inserted, one increased Be exposed to dirt. Due to the division of the insulating body, the insulating body front part can be easily replaced, without the mecha- niche or electrical connection of a cable, which is connected to the Isolierkörperhinterteil to solve. The accessibility of the Isolierkörpervorderteilils is usually very good from the plug side, so that a replacement process can be performed quickly and easily. A recorded in Isolierkörpervorderteil conductor can form an electrical connection with a recorded in Isolierkörperhinterteil conductor by the two conductors abut each other axially. For this purpose, at least one of the conductors can be made axially elastic in order to increase contact reliability. In another variant, the electrical connection between the two conductors can be formed by means of a non-axial contact element. An electrical and mechanical contact between the conductors can be produced by a mutual contact in non-axial direction, ie in particular in the radial or tangential direction, relative to a longitudinal axis of the connector. For example, one of the conductors may include a pin and the other may include a sleeve or tube that may be axially joined together. The plant of the conductors can in this case act in particular perpendicular to the axial direction, for example in the form of a clamping force of the tube or a lateral elastic contact tongue on the pipe or on the pin.

The housing may comprise a housing rear part and a housing front part which can be separated therefrom, it being possible for the insulating body front part to be removed from the insulating body rear part when the housing front part is separated from the housing rear part. The housing front part can lock the insulating body front part in the housing. The maintainability of Isolierkörpervorderteils can be further increased. In addition, the front housing part, which itself may be exposed to high mechanical stress, be separately interchangeable. In one embodiment, the housing front part and the insulating body front part are provided as an integrated, separately manageable unit, so that they can be replaced in an improved manner together.

The housing rear part is preferably configured to be inserted into a stepped bore, wherein the connector further comprises a screw element which is adapted to form a screw connection with a thread on the stepped bore, to press the housing front part axially against the housing rear part. The stepped bore includes at least a smaller bore, a larger bore, and a radial shoulder between the bores. The cable can be passed through the smaller hole. The thread may be provided as an internal thread on the larger diameter, wherein the screw element comprises an external thread. In another embodiment, an external thread is mounted in the region of the stepped bore and the screw is equipped in the manner of a nut, such as a union nut, with an internal thread. In both cases, the screw preferably has an axial recess through which a portion of the connector or the other connector may extend. The screw can be driven by means of a special key, in particular, it may have end holes for engagement of a Stirnlochschlüssels.

The housing can be designed as a full metal housing, so that it can fulfill a shielding function. For this purpose, it can in particular be connected in a conductive manner to a further element of the plug connection which can be used for shielding, for example by means of a contact lamella.

The insulator front portion and the insulator back portion may each comprise an electrically conductive shield plane shielding a first group of conductors from a second group of conductors, and shield layers of the insulator body portion and the insulator body portion form a releasable electrical connection with each other. As a result, the groups of conductors can be shielded from one another in the region of the insulating body. In particular, in conjunction with a further shield located radially outside the conductor, for example in the form of the conductive housing, the groups can thus be shielded in the radial direction in an improved field-tight manner.

At Isolierkörpervorderteil or Isolierkörperhinterteil several shielding levels can be provided, which are adapted to each shield pairs of conductors against each other. In a particularly preferred embodiment, the shield planes intersect along an axial sectional area, so that the shield planes form an X-shaped structure when viewed axially, in each of which four quadrants a group of conductors lies. Each group may comprise two conductors, so that a total of eight conductors in pairs of two conductors are shielded from each other.

The Isolierkörperhinterteil may have on its side facing away from the Isolierkörpervorderteil side a plug for contacting the guided in the insulating body plurality of conductors. In particular, the plug can comprise an X-coded connection plug, which is preferably equipped with an M12 plug-in or screw connection.

An automatic electrical coupling device for attachment to a rail vehicle includes at least one connector as described herein. A connection or release operation of the plug-in connection, like a coupling or decoupling operation of two rail-bound vehicles or vehicle parts, can take place by relative, substantially axial movement. The closing or opening of the connector of the coupling device can be carried out automatically parallel to connecting or disconnecting the vehicle parts.

The coupling device may comprise a contact carrier with a recess in which the connector is received over at least a portion of its extension in the longitudinal direction. The contact carrier may in particular be attached to or covered by a coupling device for the mechanical coupling of vehicles. More preferably, the contact carrier may comprise a contact element between the vehicles. Preferably, the coupling device comprises a plurality of plug-in connections, which in particular can be arranged such that the vehicle is reversible. One or more connectors may be redundant and more preferably complementary to the coupling device. The connectors can be arranged so left and right of a central axis of the track-guided vehicle, that the vehicle is reversible. For example, a male and a female connector may be disposed on opposite sides of a central axis of a first vehicle.

In other words, a first vehicle may alternatively be coupled with its front side or its rear side with the same side of a second vehicle. At the The front and the rear of the first vehicle each have a plurality of plug connections are provided and mounted such that in the front and the rear side coupling with the second vehicle, an electrical connection can be made. About the electrical connection, a data connection can be made.

GENERAL BENEFITS Generally, a data bus connector for establishing a data connection between two vehicle parts for transmitting data at a data rate greater than 1 Gbit / s may include a housing and an insulator having a plurality of internally insulated conductors to be disposed within the housing. The conductors can therefore be embedded, for example, in the insulating body and thereby isolated from each other. The insulating body has a Isolierkörperhinterteil and one with the Isolierkörperhinterteil electrically and mechanically connectable Isolierkörpervorderteil, wherein the Isolierkörperhinterteil is connectable to a data cable and the Isolierkörpervorderteil is connectable to a Isolierkörpervorderteil another data bus connector. For this purpose, the insulating body front part can be designed, for example, as a male variant in a first data bus connector and as a female variant in the second data bus connector. In this case, a part of the plurality of conductors can be shielded within the insulator against other conductors of the plurality of conductors. For example, the data-carrying conductors within the insulator may be shielded in pairs from each other. Thus, not only is a shield surrounding the plurality of electrical conductors provided outwardly, but preferably individual conductor pairs are provided with a shield so that, for example, unwanted crosstalk, i. significantly reducing the spread of signals from one line pair to another line pair, and thus improve the signal quality so that the desired data rates of 10 Gbit / s and beyond can be achieved. The shielding can be designed, for example, as a planar separation of individual regions of the insulating body, so that, for example, two pairs of conductors each are located in such a shielded region.

The shield on the data bus connector may be routed throughout the entire data bus connector to achieve high signal quality. Especially with a two- Partial structure of the insulating body in Isolierkörpervorderteil and Isolierkörperhinterteil it is advantageous if the shield between the two parts, for example, by contact blades or the like is passed. In particular, the number of conductors can be eight, so that result in a preferred embodiment, four pairs of lines, which are each shielded from each other. To simplify the assembly, the Isolierkörperhinterteil may have on its side facing away from the Isolierkörpervorderteil a plug for contacting the guided in the insulating plurality of conductors. The said connector may be, for example, an X-coded connector (male or female) of an M12 male or female connector. This serves to connect the supplied line. By such a connector eliminates the mechanical processing for connecting the cable during assembly. The housing may be designed as a full metal housing, for example with a plated surface. Thus, the housing already forms a shield to the outside. Preferably, the outer shield may also be connected to the inner shield between the pairs of conductors. The housing may be mechanically connectable to an electrical contact coupling. The connection can be designed, for example, as a screw connection. The housing may further comprise a contact blade for an electrical shield connection. The contact lamella can be set up to produce an electrical contact, in particular in the lateral or radial direction, and is preferably designed to be elastic in this direction. Thus, an externally guided shielding can be easily transferred into the housing.

An automatic electrical coupling device for a rail vehicle includes at least two data bus connectors as described herein. The automatic electrical coupling device may include a contact carrier having a plurality of recesses in which the data bus plugs are received over at least a portion of their extent in the longitudinal direction. The data bus connectors on the automatic electrical coupling device may be arranged such that the vehicle is reversible. BRIEF DESCRIPTION OF THE DRAWINGS

In further embodiments, the leads or conductors 163, 164 may also be sheathed in pairs with suitable shielding. Furthermore, the shielding levels 1613 need not be consistently formed as planes. Rather, a suitably dense number of individual elements such as wires, powdery metal particles or other conductive shielding may be provided. The shielding elements can be incorporated into the material of the insulating body 16 or applied to a surface, for example as a coating, to perform the intended shielding function. For example, the insulating body 161, 162 could each be made of four individual elements, which are each coated electrically shielding at corresponding contact surfaces and then joined together to the insulators 161, 162.
