Description

Plug connector with contacts for signal data transmission

The invention relates to a plug connector with electrical contacts for the transmission of signals or signal data, in which at least four contacts with power lines are electromagnetically and / or metallic shielded against other contacts with power lines within the plug connector and, in particular, serve as Ethernet connections, so that at least one or each shield provided within the plug connector contains only two corresponding contacts of this type with power lines.

A plug connector of this type is known from DE 195 26 113 A1. In this case, it has armored contacts in pairs. In addition, the possibility of providing, in addition to these pairs of shielded wires, in the so-called copper technique, also connections for light waveguides is described. In addition, individual armored wires can also be included or also several pairs of shielded wires.

In this way, in addition to additional light waveguides, the possibility of providing other shielded contacts, whether individual or in pairs, is obtained, which means a considerable expenditure of space and leads in such a configuration to a connector of expensive plug to manufacture.

Therefore, there is the task of creating a plug connector of the type mentioned at the beginning, in which the advantage is maintained that the at least four contacts and lines are shielded with respect to the remaining contacts and lines and at the same time further reduces the danger of interference in these contacts and armored lines. In this case, manufacturing should be as simple as possible.

For the solution of this apparently contradictory task, it is provided that the contacts and armored lines in pairs are shielded against other unshielded electrical contacts with power lines inside the plug connector, that the shields are configured of the type of socket and are arranged to mutual distance between each other, that the shields of the type of socket or in the form of a socket have a circular round cross-section, that as many shields are provided inside the plug connector as pairs of contacts with power lines must be shielded in front of other contacts with lines of supply, and each of these shields contains / comprises a pair of contacts with power lines and that the distance of the plurality of shields provided within the plug connector from each other is approximately from a quarter to about a millimeter.

In this way, the advantage of having, on the one hand, the usual contacts with power lines and, on the other hand, of having those that are electromagnetic and / or mechanically shielded, on the one hand, is maintained so that in order to achieve The smallest possible danger of interference is only provided in each case with two contacts within a shield and these shields have a circular round cross-section, allowing for easier manufacturing and assembly. In this way, the shield can be manufactured, on the one hand, in a very simple way, for example from a tube or similarly as a bushing with circular cross-section and can be provided, for example, for fixing with an internal thread or external thread, the supports, which carry the contacts with power lines, can easily be screwed into the internal thread, for mounting inside the shield.

Therefore, according to the invention, as many individual shields in the socket form are present in a particularly convenient manner with circular round cross-section as pairs of Ethernet lines are present in the plug connector, so that they can be used thereto. other contacts without shielding time in the usual way.

Therefore, as many circular round shields in the cross section as pairs of contacts with power lines can be provided in front of other contacts with power lines, and each of these shields can contain / comprise a pair of contacts with power lines. In this way, these pairs of contacts to be shielded with power lines are not only shielded forward with respect to other contacts with power lines, but also mutually shield each other.

The reduced distance from about a quarter to about one millimeter between the individual shields also allows it to be accommodated in smaller plug connectors, while a slightly larger distance reduces or excludes the danger of unwanted contacts of the shields during assembly and during installation. subsequent manipulation In this case, the distance of the plurality of shields from each other that provided within the plug connector may be approximately half or approximately three quarters of a millimeter or a value that is between a quarter and a millimeter.

In this case, it is favorable that the bushings that serve as shields protrude above the front side of the plug connector or its housing in an axial direction on the side that is remote from an opposite part of the

plug connector, and that the power lines to be shielded are shielded already outside the housing of the plug connector with respect to each other and in relation to other power lines. Correspondingly, the danger of interference is reduced.

The support of the two contacts, which can be accommodated in each case within a shield, with power lines can be configured as a threaded part and can be inserted or screwed into an internal thread of the shield type. In this case, such a configuration as a threaded part in the support has the advantage that at the same time also the shield braid can press after its flexion on the inner side in the shield bushing. In addition, this results in a discharge of the traction for the contacts, arranged in the individual shields of the bushing type, with feeding lines or twisted wires.

The plug connector according to the invention can be attachable from two plug parts, so that one plug piece can have contacts configured as pins and the other plug part effective as a counter part can have contacts configured as bushes. They adjust with the plugs, which establish an electrically conductive plug connection in the assembled position of the two plug parts and in both plug parts, shields can be provided respectively for corresponding contacts in pairs with power lines and the shields of both plug parts can be plugged by force application to each other. The plug connector can therefore be equipped with two plug pieces, in which in each case, in accordance with the invention, shields for corresponding contacts in pairs with power lines are provided which, in turn, they can be assembled together, to allow the connection of the plug parts without problem and to carry out in this coupled position a continuous shield.

The shields of the socket type of one of the plug pieces can be grooved and the shields of the socket type of the other plug piece can be received inside each other or can overlap in an elastic manner in a mutually coupled position. Through the grooves of the shields, these can be adapted correspondingly elastically to the shields found in the opposite part of the connector.

It should still be mentioned that the insulation bodies arranged in the plug parts and having the contacts and the power lines can be configured in such a way that they can optionally receive pins or bushes as contacts. In this way, manufacturing can be streamlined or simplified.

Especially in the case of combining some or several of the characteristics and measures described above, a plug connector with electrical contacts is obtained for the transmission of signals or signal data of different speeds and valences, at least four of these contacts being shielded with power lines in such a way that an own contact is present in each case for two corresponding contacts by pairs of this type, so that each of the shields provided - additionally - inside the plug connector contains only two contacts and lines of corresponding feeding. Correspondingly, the danger of mutual interference within the plug connector is reduced.

An embodiment of the invention is described in detail below with the help of the drawings. The following is shown in partially schematic representation:

Figure 12 shows a representation, corresponding to Figure 10, of an insulating body with the contacts arranged on the outside and with four pairs of shielded contacts for Ethernet lines, including its circular round shields.

A designated plug connector, in general, with the number 1, contains electrical contacts for the transmission of signals or signal data of different valences. In this case, two different plug connectors 1 are provided, which can be coupled to each other and generally result in a connector shown by way of example in Figure 3, so that in Figure 3 the two connectors of Plug 1 are not yet coupled to each other.

Especially in figures 10 to 12, but also in figures 4 and 5 it is recognized that in this case each plug connector 1 contains four contacts 2 or 3 with power lines 4, which are shielded against other connectors 5 with lines power supply 6 within the respective plug connector 1 electromagnetically and / or mechanically in a manner that will still be described, and which can serve as Ethernet connections, when two plug connectors that fit together are connected or coupled together in each case. according to figures 3 and 11.

In this case, especially in Figures 4 and 5, 6 and 7 as well as 10 to 12 it is illustrated that in each case two corresponding 2 or 3 contacts in pairs with their power lines 4 are shielded separately within the connector of respective plug 1, that is to say that two corresponding contacts 2 in pairs, on the one hand, and two corresponding contacts in pairs 3, on the other hand, in each case have their own shield, so that both plug connectors 1 are present , respectively, two shields 7 and each shield 7 contains within the plug connector 1 only two corresponding contacts 2 or 3 with power lines 4. This is particularly well recognized, for example, in Figure 4 or also in Figures 8 or 10.

Therefore, within the respective plug connector 1 as many shields 7 are provided as pairs of contacts 2 or 3 with contact lines 4 must be shielded in front of other contacts 5 with power lines 6, and each of these shields surrounds only one pair of contacts 2 or 3 with power lines 4.

In this case, it is especially well recognized in Figures 4 and 5 that these shields 7 are configured of the type of socket or in the form of a socket and with the help of Figures 8 to 10 and 12 it can be recognized that these shields 7 of the type They are arranged in the respective plug connector 1 in the use or assembly position at a mutual distance from each other, that is, they do not touch.

This mutual distance of the plurality of shields 7 provided within the respective plug connector 1 can be from about a quarter to about one millimeter, for example about half or about three quarters of a millimeter, so that the distance can, however, be also among these values.

The bushes that serve as shields 7 protrude, according to figures 1, 3 and 11, above the front side of the respective plug connector 1 or of a corresponding insulation body 8 or also of the housing 9 that receives this body of insulation 8 in axial direction on the respective opposite part of the plug connector 1, so that the power lines 4 to be shielded are shielded already outside the housing 9 of the respective plug connector 1 relative to each other and in relation to other power lines 6. This can be especially clearly recognized in each case in the two different plug connectors 1 on sides away from each other of protruding shields 7 in figure 11, so that in figure 11 they are not shown for clarity the corresponding covers 9, which can be configured differently according to figures 1 and 2 or according to figure 3.

According to figures 4, 5, 10 and 12, the shields 7 of the bushing type have a round cross section

circular and in these shields 7 are provided insulation elements 10 correspondingly configured with retention clips 11 for the mooring of contacts 2 or 3, in which contacts 2 or 3 can be inserted, in each case, in recesses 12 corresponding, so that a support 13 with an outer thread 14 as an outer closure is additionally provided, which fits and can be screwed with its outer thread 14 into an inner thread 15 of the bushing-shaped shield 7. The contacts 2 or 3 still represented individually in Figures 6 and 7 and the parts that support them within the respective shield 7 as well as these shields 7 can be recognized in a composite arrangement in Figures 4 and 5. With the aid of the support 13, according to FIG. 9, a shield braid 7a can still be attached inside the shield bushing 7, which results in a strain relief. The round circular shape of the shields 7, which can be recognized in Figures 10 and 12, facilitates the provision of the internal thread 15 in these shields.

The two plug connectors can also be considered as plug parts that, once assembled, result in the definitive plug connection, so that a plug connector 1 or plug part has contacts 2 configured as pins - listed below as "pins 2" and the other plug connector or plug part has 3 connected configured as sockets adapted to these pins 2 - hereinafter also referred to as "sockets 3" - which, in the assembled position, result in a connection of conductive power plug. In this case, two shields 7 for corresponding contacts 2 or 3 in pairs with power lines 4 are provided in the two plug connectors or connection pieces 1 and these shields 7 of the two plug connectors 1 can be plugged in. , on the other hand, inside each other, when the plug connection of the two plug connectors or connection pieces is established.

In Figures 5, 7 and 11 it can be recognized that the shields 7 of the bushing type of one of the connection pieces 1 are grooved. In this way it is possible that they receive in themselves the shields 7 of the type of socket of the other plug part or plug connector 1 in the coupling position and overlap in an elastic manner, so that also the shields 7 of the two connectors of plug 1 in use position result in a mutual extension.

In Figures 4 and 5 as well as 11 it is still indicated that the insulation bodies 8, which have contacts 2 or 3 and the power lines 4 and which are arranged in the plug parts, can be configured in such a way so that pins 2 or bushings 3 can be selectively received as contacts, which facilitates manufacturing.

The fixing of the insulation bodies 8 inside the housing 9 and the anchoring of the contacts 5 with their supply lines 6 inside the insulation bodies 8 are indicated in different figures, for example in figures 2 and 8 as well as in Figure 9 and correspond to usual mounting arrangements of this type. Also the fixing of the insulation bodies 8 inside the housing 9 for example with the help of a flange 16 and a projection 17 disposed therein on the outer side is known in practice for comparable plug connectors and in this case also those plug connectors, in which four contacts 2 or 3 are housed in a common shield 7, while in the exemplary embodiments, unlike such usual plugs and plug connectors 1, two corresponding contacts 2 or 3 have in each case own shield 7.

The plug connector 1 with electrical contacts for the transmission also of signals or data of high-value signals contains at least four contacts 2 or 3 with corresponding power lines 4, which are electromagnetic and mechanically shielded in front of other contacts 5 with power lines. power 6 for the transmission of signals of lower valence within the respective plug connector or plug part 1 and can serve as Ethernet connections. In this case, at least two corresponding contacts in pairs in the form of pins or bushes 3 with their power lines 4 are shielded separately, so that each of the circular round shields 7 in the cross-section, provided within the connector Single plug 1 contains only two corresponding 2 or 3 contacts in the form of a plug or in the form of a socket with power lines 4, which improves mutual shielding.
