SYSTEM FOR PROVIDING AN ELECTRICAL CONNECTION FOR THE
TRANSMISSION OF DATA, AND COMPONENTS OF THIS SYSTEM
BACKGROUND OF THE INVENTION
System for providing an electrical connection for the transmission of data, and components of this system.
The present invention relates to a system for providing an electrical connection for the transmission of data, a patch panel for the connection of cables, a socket, and a plug-in connector, whereby these same components can be used in the system.
In general, a patch panel is a connection means that is used in the connection or, respectively, networking of terminal apparatuses, in order for example to connect an incoming data cable with several outgoing data cables. In order to determine a particular connection between a terminal apparatus, for example a printer, and another terminal apparatus, for example a personal computer, a particular plug-in connection can be set up at the patch panel, or the leads of a cable, for example coming from a wall data outlet, can be provided lead-by-lead at the patch panel, for example by means of a clamped or kinked contacting. In current connection systems with data transmission rates of tens to hundreds of megabits, or even gigabits, that is, in the radio-frequency range, high electromagnetic RF radiation results at the contact.points, for example, at the patch panel or at the wall socket, due to exposed cable leads and incorrect installation of the metal shielding of the cable, or to excessively high contact resistances, which radiation can cause disturbances in apparatuses in the spatial vicinity of, for example, the patch panel. In addition, unwanted cross-talk couplings can occur in adjacent cable connection areas at the patch panel, which can lead in turn to disturbances of the data signals transmitted via the patch panel, and thus to a reduction of the range of the data transmission in the disturbed cable.
SUMMARY OF THE INVENTION
The object of the present invention is to indicate a connection system with a patch panel in which the above-explained disturbances due to electromagnetic RF
radiation at the connection means of the system can be at least greatly reduced.
Accordingly, the inventive patch panel has, for the connection of cables, in particular of data cables, a front side, a back side, several openings, and one or more plug-in connectors that are respectively fastened to the patch panel in accessible fashion, via one of the openings, from the front side of the patch panel for the plugging of a mating plug-in connector. A cable connection area on the back side of the patch panel is allocated to each of the plug-in connectors. Each of the plug-in connectors and its cable connection area is surrounded on all sides by an electromagnetic shielding, in particular at the back side of the patch panel.
The inventive patch panel has the considerable advantage that by means of the electromagnetic shielding, on all sides, of the respective plug-in connector, or, respectively, of its plug-in connector location, and of its respectively associated cable connection area, an electromagnetic radiation, in particular of radio-frequency energy, at the exposed cable leads and contacts in the cable connection area and in the plug-in connector area is securely enclosed or, respectively, shielded. Due to the separation, achieved by the shielding, from adjacent cable connection and plug-in connector areas, a disturbing cross-talk coupling into adjacent cables, cable connection areas, contacts and plug-in connectors is avoided, or is at least strongly suppressed. In turn, this has the consequence that the electrical signals in cables at the patch panel are more free from disturbance, and can thus be transmitted over a large distance, or, respectively, a distance greater than was the case in the prior art. In addition, the advantageous shielding of the inventive patch panel enables a suppression of electromagnetic radiation in the spatial surroundings of the patch panel, thus avoiding disturbances of apparatuses in the vicinity of the patch panel.
The shielding preferably has one or more individual shielding caps that respectively surround a plug-in connector and its associated cable connection area, whereby a modular equipping of the patch panel is enabled.
An insert is preferably arranged in each opening of the inventive patch panel, in each of which inserts a plug-in connector of the patch panel can preferably be placed, whereby the insert is arranged inside the shielding. The insert enables a precise centering, mounting and insulation, if a plastic insert is used, and a positively locking arrangement of a plug-in connector at the patch panel. In addition, the insert contributes to the ability to equip the patch panel in a modular fashion.
Each of the plug-in connectors is preferably held fast in the insert by a snap connection, which enables the plug-in connector to be plugged to the patch panel.
The patch panel preferably has an angled sheet metal part with a front part that extends vertically at the front side of the patch panel and a base part that extends horizontally at the back side of the patch panel, whereby the openings are fashioned in the front part and the angled sheet metal part forms a part of the shielding. Together with the individual shielding caps, the angled sheet metal part enables an effective shielding, particularly in the RF range.
A reinforcing part is preferably provided on the back side of the patch panel between the front part and the base part. The reinforcing part enables a stabilization of the relatively elongated angled sheet metal part, and in addition provides an additional surface for the shielding contacting.
A front plate, which holds the plug-in connectors fast on the angled sheet metal part, or additionally stops them, can be fastened on the angled sheet metal part. The front plate enables a fitting pressure on the plug-in connectors in the patch panel, whereby a reliable contacting of a shielding plate of the plug-in connector with the angled sheet metal part is realized.
The front plate is preferably fastened to the angled sheet metal part by means of a snap connection, enabling a simple attachment and removal of the front plate to and from the angled sheet metal part. In addition, the snap connection ensures a reliable fitting pressure on the plug-in connectors along the entire front side of the angled sheet metal part.
On the back side, the inventive patch panel preferably has at least one cable carrier as support for a cable, thus avoiding an unwanted kinking of the cable, particularly in the cable connection area, which can otherwise lead to an increased damping or damage of cable leads, or also of the metal sheath of the cable.
Preferably, the plug-in connector has at least one plug-in jack for receiving a plug on the front side of the patch panel, and a terminal strip on the back side of the patch panel for fastening the leads of a cable in the cable connection area.

On the front side 2 of the patch panel 1, the front plate 6 is fastened by means of a snap connection, whereby the front plate 6 encloses the front part 31 of the angled sheet metal part 30 at the upper side with a hook 65, and the front plate 6 engages in a snap recess 25 of the angled sheet metal part 30 with a snap projection 8.
The front plate 6 has in turn one front plate opening 9 per plug-in connector location, which is however displaced somewhat in relation to the openings 33 and 35, so that when the front plate 6 is attached a pressure is exerted on the plug-in connectors 40.
One plug-in connector 40 can be placed in each of the inserts 20. The plug-in connector 40 comprises a jack part 41 and a terminal strip part 44 that can be joined together and separated from one another.
The jack part 41 has, on the front side, two jacks 42 and 43 that are located alongside one another and are of the same size, into which corresponding mating plugs of cables fit. A shielding plate 60 is attached to the housing of the jack part 41, which plate is pressed against the front side of the front part of the angled sheet metal part 30 when the plug-in connector 40 is inserted into the insert 20, in order to create a secure ground contact with the angled sheet metal part 30. The jack part 41 has a circuit board 49 that stands off at the back side, on which the contacts of the jack part 41 are fashioned so as to be exposed. In addition, the jack part 41 has snap springs 46 that create a snap connection with the snap projections 22 of the insert 20 when the plug-in connector 40 is plugged in. The jack part 41 can for example be designed as an SML insert.
The terminal strip part 44 has on the front side a jack 48 into which the circuit board 49 can be fitted by plugging, and has on the back side a terminal strip 47 with clamp contacts located alongside one another, which contacts are continued in the jack 48 inside the terminal strip part 44, in order to make contact with corresponding contacts of the circuit board 49 of the jack part 41, whereby Qverall a continuous electrically conductive connection is provided between a contact of the terminal strip 47 and a contact inside the socket 42 or, respectively, 43. The leads 62 of the data cable 61 are hooked into the clamp contacts of the terminal strip 47 and are held fast by means of a clamp part of the terminal strip 47 that applies the necessary contact pressure. A snap spring 45 is fashioned on the terminal strip part 44, which, when the plug-in connector 40 is placed in the insert 20, forms a secure snap connection together with the snap projection 21 of the insert 20 and the stops 23 for the terminal strip part 44. The terminal strip part 44 can be fashioned as an EDGE contact.
On the back side of the insert 20 or, respectively, the plug-in connector 40 inserted therein, a cable connection area 5 is provided in which the data cable 61 extends with its end, at least for a part or a segment, and in which the leads 62 of the data cable 61 are fastened on the terminal strip 47 of the plug-in connector 40. The data cable 61 is for example fastened to the cable carrier 7 by means of a cable clip (not shown in Figure 5). A metal sheath of the data cable 61 is likewise connected with the angled sheet metal part 30 inside the cable connection area 5.
On the back side of the patch panel 1, the insert 20 and the associated cable connection area 5 is shielded by means of the shielding cap 10, which covers opposite side walls 12 and 13, a roof wall 16 and a back wall 14, and engages, with a hook 15, in an associated eye on the angled sheet metal part 30 or, respectively, on the reinforcement part 34 on the upper side, for fastening. The plug-in connector 40 and the associated cable connection area 5 are thereby surrounded on all sides by metallic shielding walls of the shielding cap 10 and of the angled sheet metal part 30, whereby the access to the jacks 42, 43 of the plug-in connector 40 is exppsed. Due to the all-around shielding by means of the shielding cap 10 and the angled sheet metal part 30, electromagnetic RF radiation occurring in the cable connection area 5 can no longer reach adjacent plug-in connectors 40, whereby cross-talk attenuation or disturbances connected therewith are avoided. Thus, according to the present embodiment a maximum of nine plug-in connector locations can be provided on the patch panel 1, and a corresponding number of shielding caps 10 can be installed in modular fashion. A
reliable ground contact with a low contact resistance between the shielding caps 10 and the continuous angled sheet metal part 30 can for example be created by fastening pins and clamps. The patch panel 1 is constructed as a drawer in a 19-inch location of a corresponding 19-inch cabinet.
All metal parts of the patch panel 1, that is, the front plate 6, the angled sheet metal part 30, the reinforcement part 34 and the shielding caps 10 are made of high-grade steel, for example, X Cr 17 or X6 Cr 17 (Remanit), with a particularly smoothly milled surface, so that additional contact resistances due to recesses in the material, a rough surface, or other disadvantageous surface treatments, are avoided.
The assembly of the patch panel 1 is explained below on the basis of a plug-in connector 40. The insert 20 is inserted from the front side 2 of the patch panel 1 through the opening 4 and the openings 33 and 35. Subsequently, the leads 62 of the data cable 61 are clamped onto the terminal strip 47 of the terminal strip part 44 inside the cable connection area 5. Subsequently, at the back side 3 of the patch panel 1 the terminal strip part 44 of the plug-in connector 40 is inserted into the back side of the insert 20, until the snap spring 45 snaps into the snap projection 21 of the insert 20, and the terminal strip part 44 comes to rest on the stops 23 of the insert 20. The cable 61 is fastened to the cable carrier 7 by means of the cable clip. The shielding cap 10 is hung on the back side 3 of the patch panel 1 by means of its hook 15, and its back wall 14 thereby comes to rest at least partly on the cable carrier 7. The data cable 61 thereby extends through a cap opening 11 that is fashioned in the back wall 14 of the shielding cap 10. From the front side 2 of the patch panel 1, the jack part 41 of the plug-in connector 40 is then introduced into the insert 20, whereby the circuit board 49 is inserted into the jack 48 of the terminal strip part 41 until the snap springs 46 of the jack part 41 create a snap connection with the snap projections 22 of the insert 20. The shielding plate 60 of the plug-in connector 40 is thereby pressed against the front side of the front part 31 of the angled sheet metal part 30, in order to set up a contact between the angled sheet metal part 30 and the shielding plate 60, that is, the plug-in connector 40. Subsequently, the front plate 6 is attached to the front side of the patch panel 1 by means of the snap connection of the snap recess 25 and the snap projection 8, whereby an additional pressure is exerted on the front side of the plug-in connector 40 by the front plate 6. Cables with corresponding mating plugs or, respectively, plugs can now be inserted into the jacks 42, 43, in order to create additional connections.
The inventive socket 50 is for example fashioned as a flush-type box for wall mounting with a flush-type frame 64, and essentially comprises the plug-in connector 51, which is identical to the plug-in connector 40, a plastic insert 57 that is identical to the insert 20 of the patch panel 1, a sheet metal bent part 55 and a shielding cover 59 that is arranged on the back side of the socket 50, and the plug-in connector 51, a cable connection area 56 that is provided at the back side inside the shielding cover 59, and that surrounds the sheet metal bent part 55 at the back side._ The shielding cover 59 and the sheet metal bent part 55, which occupies the interior space (adjacent to the cable connection area 56 and to the insert 57) of the socket 50 up to the height of the flush-type frame 64, form the shielding of the socket 50. In the cable connection area 56, the leads of the first data cable 52 are clamped to the terminal strip 47 of the plug-in connector 51, whereby the data cable 52 is secured to the back side of the sheet metal bent part 55 with a cable clip 53. A cable binder 66 additionally secures the first data cable 52 to a fastening projection 54 of the sheet metal bent part 55 in strain-relieved fashion. The sheet metal bent part 55 and the insert 57 can be inserted through the opening 58 of the socket 50, whereby snap connections hold the sheet metal bent part 55 and the insert 57 on the flush-type frame 64. The shielding cover 59 is fastened to the flush-type frame 64, for example, by means of brackets, pins or screws and the like, or also in positively locking fashion. When the plug-in connector 51 is snapped into place, the shielding plate 60 of the plug-in connector 51 is pressed against the sheet metal bent part 55 for the contact switching. The metal parts of the socket 50, that is, the sheet metal bent part 55 and the shielding cover 59, are also made of the high-grade steel with a smoothly milled surface, mentioned above in connection with the patch panel 1. A guide opening 63 for the cable 52 is provided in an edge area of the shielding cover 59. In addition, a second guide opening can be fashioned in the shielding cover 59.
The invention is not limited to the particular details of the apparatus depicted and other modifications and applications are contemplated. Certain other changes may be made in the above described apparatus without departing from the true spirit and scope of the invention herein involved. It is intended, therefore, that the.subject matter in the above depiction shall be interpreted as illustrative and not in a limiting sense.
The inventive plug-in connector preferably has a snap means for the pluggable fastening of the plug-in connector, for example, in the patch panel or in the socket.
The inventive plug-in connector preferably has a jack part with at least one jack and a terminal strip part with the terminal strip, whereby the jack part and the terminal strip part are designed as parts that can be joined together and separated.
The two-part design of the inventive plug-in connector has the advantage of a simple assembly of the plug-in connector itself and the cost-saving and modular fastening of the plug-in connector to the patch panel or to a socket.
Snap means are preferably fashioned on the terminal strip part and/or on the jack part in order to enable a pluggable fastening of the plug-in connector, and also of its individual parts, on the patch panel and/or the socket.
The shielding plate is preferably fastened on the jack part, in order to achieve a compact construction.
The inventive system for the provision of an electrical connection for transmitting data comprises a first cable that has several electrically conductive leads, a socket with at least one plug-in connector fastened in the socket in accessible fashion, through an opening on the front side of the socket, for the plugging of a mating plug-in connector.
A cable connection area is provided in the interior of the socket. The plug-in connector and the cable connection area is surrounded on all sides by an electromagnetic shielding. The leads of the first cable are connected with the plug-in connector in the cable connection area of the socket, a second cable with several electrically conductive leads and with a mating plug-in connector that is plugged into the plug-in connector of the socket at the front side, a patch panel that comprises a front side, a back side, several openings, and one or more plug-in connectors that are respectively fastened to the patch panel in accessible fashion, from the front side of the patch panel via one of the openings, for the plugging of a mating plug-in connector.

Each of the plug-in connectors and its cable connection area is surrounded on all sides by an electromagnetic shielding. The leads of the second cable are connected with one of the plug-in connectors of the patch panel in the cable connection area of the plug-in connector, or a second mating plug-in connector of the second cable is plugged into a plug-in connector on the front side of the patch panel.
The inventive system comprises the above-explained inventive components, such as the patch panel, socket and plug-in connector, and consequently also comprises the sum of the advantages thereof. The inventive system thus provides a link for the transmission of data, whereby an electromagnetic radiation, in particular of RF energy, at the exposed cable leads and contacts in the cable connection area and in the plug-in connector area of the link is trapped or shielded by the shieldings of the system components. Due to the separation (achieved by the shieldings) from adjacent cable connection and plug-in connector areas, a disturbing cross-talk coupling into adjacent cables, cable connection areas, contacts and plug-in connectors of the system is avoided or at least strongly suppressed. The electrical signals in cables of the inventive system are thus more free of disturbances, and can thus be transmitted over _g_ a broad distance, or, respectively, a distance broader than was the case in the prior art.
In addition, the advantageous shieldings of the system components enable a suppression of electromagnetic radiation in the spatial surroundings of the system, whereby disturbances of equipment in the surrounding environment of the system are avoided.
Preferably, the plug-in connectors and the associated inserts of the patch panel and the plug-in connector and the insert of the socket have the same construction, whereby an extensive modular construction and a component exchangeability of the patch panel and of the socket are enabled. .

DESCRIPTION OF THE PREFERRED EMBODIMENT
An embodiment of the inventive system comprises at least one inventive patch panel 1 (see Figures 1 to 3 and Figures 5 to 7) having at least one inventive plug-in connector 40 (see Figure 4), an inventive socket 50 with a plug-in connector 51 (see Figures 8 and 9), a first data cable 52 whose leads are connected with the plug-in connector 51 inside a cable connection area 56 of the socket 50, and a second data cable 61 (see Figure 5) that connects the plug-in connector 51 of the socket 50 with the plug-in connector 40 of the patch panel 1. The second data cable 61 has, at one end, a mating plug (not shown) that fits into a jack 42, 43 of the plug-in connector 51 of the socket 50, and is contacted at the other end with the plug-in connector 40 of the patch panel 1 with its leads, freed from the cable cladding, in a cable connection area 5 of the patch panel 1. The plug-in connectors 51 and 40 are of identical construction.
The patch panel 1 of Figures 1 to 7 comprises an angled sheet metal part 30, a front plate 6 that is fastened to the angled sheet metal part 30, one or more plug-in connectors 40 that are arranged alongside one another in a row in the patch panel 1 at corresponding plug-in connectors locations, and a number of individual shielding caps 10 corresponding to the number of installed plug-in connectors 40, one such cap being shown in detail in Figure 3. The elongated angled sheet metal part 30, which is of continuous construction, is designed as a sheet metal bent part, and has a front part 31 that extends vertically and a base part 32 that extends horizontally.
The front part 31 has one front part opening 33 per plug-in connector 40 that is open towards a front side 2 of the patch panel 1 or, respectively, is accessible from the front side 2 of the patch panel 1. The base part 32 of the one-piece angled sheet metal part 30 encloses the patch panel 1 completely towards the bottom, and has several cable carriers 7 fashioned as extensions, whose number corresponds to the number of provided plug-in connector locations of the patch panel 1, that is, nine cable carriers 7 in the embodiment shown. The respective end of the data cable 61 rests at least partly on the cable carrier 7, in order to avoid a kinking of the data cable 61, at least in the cable connection area 5 of the patch panel 1. On the back side on the front part 31,, a reinforcement part 34, which serves to stabilize the angled sheet metal part 30, is fastened to the front part 31 and to the base part 32. The reinforcement part 34 has an opening 35 that is oriented flush with the opening 33 of the front part.
An insert 20 is introduced into the openings 33 and 35 from the front side 2 of the patch panel 1. The insert 20 is made of plastic and has, on its inner upper side, a snap projection 21, stops 23, and, arranged laterally on the inside wall, two snap projections 22 lying opposite one another. The insert 20 is open at the front and back sides, and is provided for the reception of the plug-in connector 40. One insert 20 is also provided per plug location.
On the front side 2 of the patch panel 1, the front plate 6 is fastened by means of a snap connection, whereby the front plate 6 encloses the front part 31 of the angled sheet metal part 30 at the upper side with a hook 65, and the front plate 6 engages in a snap recess 25 of the angled sheet metal part 30 with a snap projection 8.
The front plate 6 has in turn one front plate opening 9 per plug-in connector location, which is however displaced somewhat in relation to the openings 33 and 35, so that when the front plate 6 is attached a pressure is exerted on the plug-in connectors 40.
One plug-in connector 40 can be placed in each of the inserts 20. The plug-in connector 40 comprises a jack part 41 and a terminal strip part 44 that can be joined together and separated from one another.
The jack part 41 has, on the front side, two jacks 42 and 43 that are located alongside one another and are of the same size, into which corresponding mating plugs of cables fit. A shielding plate 60 is attached to the housing of the jack part 41, which plate is pressed against the front side of the front part of the angled sheet metal part 30 when the plug-in connector 40 is inserted into the insert 20, in order to create a secure ground contact with the angled sheet metal part 30. The jack part 41 has a circuit board 49 that stands off at the back side, on which the contacts of the jack part 41 are fashioned so as to be exposed. In addition, the jack part 41 has snap springs 46 that create a snap connection with the snap projections 22 of the insert 20 when the plug-in connector 40 is plugged in. The jack part 41 can for example be designed as an SML insert.
The terminal strip part 44 has on the front side a jack 48 into which the circuit board 49 can be fitted by plugging, and has on the back side a terminal strip 47 with clamp contacts located alongside one another, which contacts are continued in the jack 48 inside the terminal strip part 44, in order to make contact with corresponding contacts of the circuit board 49 of the jack part 41, whereby Qverall a continuous electrically conductive connection is provided between a contact of the terminal strip 47 and a contact inside the socket 42 or, respectively, 43. The leads 62 of the data cable 61 are hooked into the clamp contacts of the terminal strip 47 and are held fast by means of a clamp part of the terminal strip 47 that applies the necessary contact pressure. A snap spring 45 is fashioned on the terminal strip part 44, which, when the plug-in connector 40 is placed in the insert 20, forms a secure snap connection together with the snap projection 21 of the insert 20 and the stops 23 for the terminal strip part 44. The terminal strip part 44 can be fashioned as an EDGE contact.
On the back side of the insert 20 or, respectively, the plug-in connector 40 inserted therein, a cable connection area 5 is provided in which the data cable 61 extends with its end, at least for a part or a segment, and in which the leads 62 of the data cable 61 are fastened on the terminal strip 47 of the plug-in connector 40. The data cable 61 is for example fastened to the cable carrier 7 by means of a cable clip (not shown in Figure 5). A metal sheath of the data cable 61 is likewise connected with the angled sheet metal part 30 inside the cable connection area 5.
On the back side of the patch panel 1, the insert 20 and the associated cable connection area 5 is shielded by means of the shielding cap 10, which covers opposite side walls 12 and 13, a roof wall 16 and a back wall 14, and engages, with a hook 15, in an associated eye on the angled sheet metal part 30 or, respectively, on the reinforcement part 34 on the upper side, for fastening. The plug-in connector 40 and the associated cable connection area 5 are thereby surrounded on all sides by metallic shielding walls of the shielding cap 10 and of the angled sheet metal part 30, whereby the access to the jacks 42, 43 of the plug-in connector 40 is exppsed. Due to the all-around shielding by means of the shielding cap 10 and the angled sheet metal part 30, electromagnetic RF radiation occurring in the cable connection area 5 can no longer reach adjacent plug-in connectors 40, whereby cross-talk attenuation or disturbances connected therewith are avoided. Thus, according to the present embodiment a maximum of nine plug-in connector locations can be provided on the patch panel 1, and a corresponding number of shielding caps 10 can be installed in modular fashion. A
reliable ground contact with a low contact resistance between the shielding caps 10 and the continuous angled sheet metal part 30 can for example be created by fastening pins and clamps. The patch panel 1 is constructed as a drawer in a 19-inch location of a corresponding 19-inch cabinet.
All metal parts of the patch panel 1, that is, the front plate 6, the angled sheet metal part 30, the reinforcement part 34 and the shielding caps 10 are made of high-grade steel, for example, X Cr 17 or X6 Cr 17 (Remanit), with a particularly smoothly milled surface, so that additional contact resistances due to recesses in the material, a rough surface, or other disadvantageous surface treatments, are avoided.
The assembly of the patch panel 1 is explained below on the basis of a plug-in connector 40. The insert 20 is inserted from the front side 2 of the patch panel 1 through the opening 4 and the openings 33 and 35. Subsequently, the leads 62 of the data cable 61 are clamped onto the terminal strip 47 of the terminal strip part 44 inside the cable connection area 5. Subsequently, at the back side 3 of the patch panel 1 the terminal strip part 44 of the plug-in connector 40 is inserted into the back side of the insert 20, until the snap spring 45 snaps into the snap projection 21 of the insert 20, and the terminal strip part 44 comes to rest on the stops 23 of the insert 20. The cable 61 is fastened to the cable carrier 7 by means of the cable clip. The shielding cap 10 is hung on the back side 3 of the patch panel 1 by means of its hook 15, and its back wall 14 thereby comes to rest at least partly on the cable carrier 7. The data cable 61 thereby extends through a cap opening 11 that is fashioned in the back wall 14 of the shielding cap 10. From the front side 2 of the patch panel 1, the jack part 41 of the plug-in connector 40 is then introduced into the insert 20, whereby the circuit board 49 is inserted into the jack 48 of the terminal strip part 41 until the snap springs 46 of the jack part 41 create a snap connection with the snap projections 22 of the insert 20. The shielding plate 60 of the plug-in connector 40 is thereby pressed against the front side of the front part 31 of the angled sheet metal part 30, in order to set up a contact between the angled sheet metal part 30 and the shielding plate 60, that is, the plug-in connector 40. Subsequently, the front plate 6 is attached to the front side of the patch panel 1 by means of the snap connection of the snap recess 25 and the snap projection 8, whereby an additional pressure is exerted on the front side of the plug-in connector 40 by the front plate 6. Cables with corresponding mating plugs or, respectively, plugs can now be inserted into the jacks 42, 43, in order to create additional connections.
The inventive socket 50 is for example fashioned as a flush-type box for wall mounting with a flush-type frame 64, and essentially comprises the plug-in connector 51, which is identical to the plug-in connector 40, a plastic insert 57 that is identical to the insert 20 of the patch panel 1, a sheet metal bent part 55 and a shielding cover 59 that is arranged on the back side of the socket 50, and the plug-in connector 51, a cable connection area 56 that is provided at the back side inside the shielding cover 59, and that surrounds the sheet metal bent part 55 at the back side._ The shielding cover 59 and the sheet metal bent part 55, which occupies the interior space (adjacent to the cable connection area 56 and to the insert 57) of the socket 50 up to the height of the flush-type frame 64, form the shielding of the socket 50. In the cable connection area 56, the leads of the first data cable 52 are clamped to the terminal strip 47 of the plug-in connector 51, whereby the data cable 52 is secured to the back side of the sheet metal bent part 55 with a cable clip 53. A cable binder 66 additionally secures the first data cable 52 to a fastening projection 54 of the sheet metal bent part 55 in strain-relieved fashion. The sheet metal bent part 55 and the insert 57 can be inserted through the opening 58 of the socket 50, whereby snap connections hold the sheet metal bent part 55 and the insert 57 on the flush-type frame 64. The shielding cover 59 is fastened to the flush-type frame 64, for example, by means of brackets, pins or screws and the like, or also in positively locking fashion. When the plug-in connector 51 is snapped into place, the shielding plate 60 of the plug-in connector 51 is pressed against the sheet metal bent part 55 for the contact switching. The metal parts of the socket 50, that is, the sheet metal bent part 55 and the shielding cover 59, are also made of the high-grade steel with a smoothly milled surface, mentioned above in connection with the patch panel 1. A guide opening 63 for the cable 52 is provided in an edge area of the shielding cover 59. In addition, a second guide opening can be fashioned in the shielding cover 59.
