Description

The present invention relates to a multimedia box.

So-called antenna doses are well known. In most cases, they are used in flush-mounted boxes. They have a device for connecting an input cable, usually in the form of a coaxial cable. If several multimedia or antenna outlets are to be connected in series one behind the other, a device for connecting an output cable is also formed on the can. Then, the supplied signals can be supplied for example in the form of television or radio programs via the respective input cable (coaxial cable) of the multimedia box and forwarded via the output cable to a respective next multimedia box.

About a provided in the multimedia box coupling device then the respective signals can be coupled when one or more subscriber terminals, for example, for receiving television programs or for receiving radio programs, etc. to be connected to the relevant multimedia box.

At the most existing antenna sockets there are at least two interfaces available, usually two coaxial interfaces, namely to connect a TV and to connect a radio. The coaxial interfaces in the form of coaxial Couplings are usually equipped so that one interface has a male configuration and the other interface has a female configuration.

Such antenna doses are ultimately multimedia doses. Multimedia doses usually include other interfaces and / or other types of interfaces, which need not necessarily be limited to coaxial interfaces for connecting coaxial cables. For example, sockets can be used to connect a telephone, modem, router, receiver or interfaces for connecting fiber optic cables. There are no restrictions in this respect. For example, a multimedia box may have four different types of interfaces.

Prior art multimedia doses include a housing and at least one connector disposed within the housing for connecting a connection cable, typically an input cable and / or an output cable. In this case, the connection device comprises an outer conductor contact device for contacting a respective outer conductor of the connection cable and an inner conductor contact device for contacting a respective inner conductor of the connection cable. The inner conductor of the connection cable is usually mechanically contacted and clamped by means of a clamping tongue which can be actuated with a screw.

Such formed multimedia cans have the disadvantage that the inner conductor after insertion or insertion must be contacted and clamped in the inner conductor contact device in a separate step by means of the actuated via the screw clamping tongue. On the other hand, in order to disconnect the connection cable from the multimedia socket, the screw actuating the clamping tongue must first be released before the inner conductor can be pulled out of the inner conductor contact device. Consequently, a tool in the form of a screwdriver and several steps are necessary for connecting and disconnecting a connection cable to / from such known from the prior art multimedia box, which makes assembly and disassembly difficult and time-extended.

From the EP 2 194 607 A1 a connector is known which has a plurality of sockets. These jacks can be designed differently. For example, these may have a sleeve shape, wherein the sleeve is designed partially slotted along its longitudinal axis, whereby a spring action sets.

From the GB 2 300 527 A is a connector for a coaxial cable known. There are shown fastening devices for a coaxial cable, which are festschraubbar to a pad, wherein when tightening the screw, the V-shaped fasteners are compressed, whereby the cable is clamped between two legs and thus locked.

From the DE 87 12 669 U1 is known an antenna socket. The inner conductors of coaxial cables to be connected clamped by a clamp body and a contact spring with the antenna socket, wherein the contact spring cuts into the inner conductor, so that they can be solved with a special tool again from the antenna box (anti-peel).

From the DE 199 38 074 A1 is known a modular antenna socket. A basic module can be permanently mounted as a flush-mounted box. A functional module, which contains a printed circuit board, can be plugged onto the basic module if required. The printed circuit board can be partially inserted through a slot in the base module in this.

The EP 2 469 666 A2 describes a multimedia box, which has a switching device to switch the multimedia socket between a terminal box and a through-can.

From the DE 10 2005 043 136 A1 An antenna socket is known which comprises a contact carrier, in which a spring clamp designed as a spring force device is arranged in a contact chamber of the contact carrier. An inner conductor of a connecting cable can be contacted by means of the spring clip and clamped in the contact chamber. The inner conductor is spring-loaded by means of the spring clip. The spring clip is fixed with its one end in the contact carrier, while by means of the other, free bent end of the inner conductor of the connecting cable is contacted. The spring clip can be compressed by pressing a arranged on the front side of the antenna box button, so that an inner conductor of a connection cable can be inserted or pulled out into the contact chamber of the contact carrier. When connecting a connection cable with such an antenna box, the button is manually pressed down, after which the inner conductor of the connection cable is inserted through an insertion funnel into the contact chamber. After removing the pressure on the probe element presses the free end of the spring clip from below the inner conductor of the connecting cable against the contact carrier, so that it is fixed in the contact chamber.

A disadvantage of an appropriately designed antenna socket is that for connecting and disconnecting a connection cable to the antenna socket always a button is to be operated, so that always two hands are necessary for connecting and disconnecting the connection cable, namely a hand for holding and guiding the connection cable and a Hand to press the button. Further, the inner conductor is contacted only at a contact point by the spring clip, wherein the free end of the spring notches in the inner conductor and thereby damaged.

The object of the present invention is therefore to provide an improved multimedia socket, which enables a tool-free and simplified connection and disconnection of a connection cable or an inner conductor of the connection cable to / from the multimedia socket, and which has improved electrical transmission characteristics.

The object is achieved by a multimedia box with the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

The multimedia box according to the invention is characterized in that the spring force device has a contacting space and an insertion opening, via which the contacting space is accessible, so that the inner conductor can be introduced into the contacting space via the insertion opening. An internal cross-section of the contacting space of the spring force means tapers in funnel shape from the insertion opening in the axial direction of the spring force means, with the result that an inner cross section of the insertion opening is larger than an inner cross section of the spring force means at an axial distance from the insertion. The inner conductor of the connecting cable can be brought into contact with the spring force device at at least two contact points and / or at least two contact regions within the contacting space. For this, the diameter of the inner conductor must necessarily be greater than a minimum inner cross section of the contacting space.

In the case of the multimedia socket according to the invention, it is possible to connect a connection cable or an inner conductor of a connecting cable to the multimedia socket merely by pushing the inner conductor into the spring force device. For this purpose, neither the use of a tool, for example in the form of a screwdriver, nor the operation of a separate button is necessary. Furthermore, the multimedia box according to the invention offers the advantage that the spring force means almost completely surrounds the inner conductor and has only a slightly larger outer diameter than this, whereby the characteristic impedance of the coaxial line can be kept constant up to the circuit board and optimum signal transmission is achieved. Furthermore, the multimedia socket according to the invention has the advantage that the inner conductor is in contact with the spring force device and thus with the inner conductor contact device at a plurality of contact points or at a plurality of contact regions, so that an improved signal transition from the inner conductor to the inner conductor contact device takes place.

The insertion of the spring force device is only slightly larger than the outer diameter of the connection cable inner conductor. Thus, the insertion opening may have an insertion diameter which is between 0.05 millimeters and 0.4 millimeters larger than the outer diameter of the connection cable inner conductor. Preferably, the insertion diameter of the spring force device between 0.1 millimeters and 0.3 millimeters larger than the outer diameter of the connection cable inner conductor. Most preferably, the insertion diameter of the spring force device is between 0.15 millimeters and 0.25 millimeters larger than the outer diameter of the lead wire inner conductor.

The shape of the spring force device can be conical, frustoconical, hyperboloid, pyramidal or similar, for example. The spring force device only has to be designed so that the inner cross section of the contacting space is funnel-shaped tapered from the insertion opening in the axial direction of the spring force device. Preferably, it is also possible that the inner cross section of the spring force device tapers from the insertion opening in its axial direction to a minimum cross section and then increases again in the axial direction directed away from the insertion opening. This offers the advantage that the inner conductor can always be pushed into the spring force device to the smallest inner cross section of the contacting space, so that the spring force device always reproducibly apart and thus exerts a reproducible radial force on the inner conductor, wherein the free end of the inner conductor continues from the spring force device remains enclosed.

According to the invention, the spring force device is designed as a spring sleeve which almost completely encloses the inner conductor and has at least one gap extending in the axial direction and over at least a partial length of the spring sleeve. In this case, a width of the gap extending transversely to the axial direction of the spring sleeve can be increased by inserting the inner conductor into the contacting space, so that the spring sleeve applies force to the inner conductor introduced into the contacting space. The force exerted by the spring sleeve on the inner conductor force acts radially on the inner conductor.

The spring sleeve consequently has two spring sleeve segments which at least partially surround the contacting space. These spring sleeve segments are through the In the axial direction over a partial length of the spring sleeve extending gap separated from each other, and the spring sleeve segments are radially apart so pressed that increases a distance between the spring sleeve segments in the region of the gap.

Preferably, the spring sleeve has a hyperboloid-like shape and comprises at least two spring sleeve segments, which are separated from each other by at least two in the axial direction and over at least a partial length of the spring sleeve extending column. The respective widths of the gaps extending transversely to the axial direction of the spring sleeve can be increased by inserting the inner conductor through the insertion opening into the contacting space, so that the spring sleeve applies force to the inner conductor introduced into the contacting space.

Correspondingly constructed spring force elements are particularly easy to produce from a sheet by punching, bending and rolling. Since the spring sleeve comprises a plurality of spring sleeve segments, an inserted into the contacting space of the spring sleeve inner conductor is contacted at a plurality of contact points, so that a reproducible and improved electrical contact between the inner conductor contact device and the inner conductor can be produced.

Preferably, the spring sleeve has three, four or more spring segments, because compared to spring sleeves with only two spring segments, a larger contact surface and thus a lower contact resistance is achieved.

The spring force device preferably comprises a stop which is opposite the insertion opening in the axial direction and which delimits the contacting space, with which the inner conductor inserted into the contacting space can be brought into contact. As a result, an end position of one end of the inner conductor is determined by the stop, whereby the end of the inner conductor does not protrude from the contacting space and is enclosed in the contacting space of the spring force device.
An appropriately designed multimedia box has the advantage that the inner conductor can not protrude from the contacting space of the spring force device, so that the free end of the inner conductor does not act as an antenna and thereby can not cause signal loss.

Of course, it is also possible that a stop penetrates into the contacting space of the spring force device or limits the contacting space without the stop being connected to the spring force device.

Preferably, the spring force device comprises a galvanically connected contact pin. As a result, a simplified connection of the spring force device and thus the inner conductor contact device with, for example, an electronic circuit is possible. Advantageously, the spring force device and contact pin or contact element are made in one piece.

According to the invention, the housing of the multimedia socket comprises a cable connection space for accommodating the at least one connection cable and a cable connection space arranged in the cable compartment and an insulating housing comprising dielectric material. The insulating housing has at least one access opening, and the at least one spring force device is arranged within the insulating housing such that the inner conductor can be inserted through the access opening and the insertion opening into the contacting space.

The multimedia box has the advantage that the spring force device is reliably galvanically isolated from the housing and can also be held and fixed by the insulating housing. The centers of the access opening of the insulating housing and the insertion of the spring force means are preferably arranged collinear to each other, so that an insertion of an inner conductor in the contacting space is easily possible.

According to the invention, the multimedia socket comprises a high-frequency-dense circuit space, and the housing comprises a bottom plate connected thereto which delimits the circuit space. In this case, the multimedia socket comprises a printed circuit board, which is arranged below the bottom plate and within the circuit space. The bottom plate also has an opening, and the inner conductor contact means is electrically connected by means of the spring force means to the printed circuit board via an electrical line projecting through the opening of the bottom plate for the exchange of data or signals.

The correspondingly constructed multimedia socket has the advantage that it can include a control and / or processing logic on the printed circuit board, wherein the inner conductor contact device low-loss is electrically connected to the printed circuit board in a particularly simple manner.

Preferably, the axial direction of the spring force device is aligned parallel to the printed circuit board. If the connection cable is connected to the multimedia socket, then run in a suitably designed multimedia box, the spring force means and the inner conductor coaxial, that is, the longitudinal axes of the spring force means and the inner conductor are collinear. Furthermore, the electrical line is preferably aligned perpendicular to the printed circuit board.

Preferably, the multimedia box further has a connection cable input side, via which the connection cable can be fed to the connection device. The terminal device comprises an outer conductor contact device for contacting an outer conductor of the connection cable, and in an end-face plan view, the outer conductor contact device is arranged between the connection cable input side and the inner conductor contact device, so that the inner conductor contact device is arranged in an end view of the connection cable input side opposite is. The inner conductor of the connection cable can be inserted or inserted via the connecting cable input side into the spring force device.

A correspondingly formed multimedia socket offers the advantage that the connection cable is merely stripped to connect a connection cable to the multimedia socket must be inserted and then from the connection cable input side in the multimedia box, so that the inner conductor is inserted into the contacting space of the spring force means, whereby a connection of a connecting cable to the multimedia box is particularly easy.

In the description that follows, like reference numerals designate like components and like features, so that a description with respect to a component once made with respect to a drawing also applies to the remaining drawings or figures, so that a repetitive description is avoided.

The FIGS. 1a . 1b and 1c show a multimedia box according to the invention 100. The multimedia box 100 comprises a generally approximately cylindrical housing 102, which is lockable on its underside with a housing cover 170. On the opposite connection or upper side two coaxial interface devices or interface body 130a, 130b are formed, which protrude from the front side of the multimedia box 100. Further, the multimedia can 100 includes a Mounting flange 104 and a support ring 104 which is provided with mounting holes 104a. The mounting flange 104 is encircling almost the entire housing 102, wherein the mounting flange 104 in which in the FIGS. 1a and 1b shown below portion of the connection cable input side 106 has a recess.

The interface bodies 130a, 130b protrude from the front of the multimedia socket 100 or from the mounting surface defined by the mounting flange 104 and each comprise cylindrical interface body outer conductors 134a, 134b and interface body inner conductors 132a, 132b arranged concentrically therewith. In this case, the points in the FIGS. 1a . 1b and 3a . 3b Interface body 130a shown on the top left has a so-called male configuration, in which an interface body inner conductor 132a is plug-shaped. The interface body 130b has a so-called female configuration in which an interface body inner conductor 132b is female-shaped.

On the outside of the housing 102 two Spreizbügel 109 are attached, by means of which the multimedia box 100 can be spread in intended for this space, such as wall holes or concealed appliance boxes.

From the FIGS. 1a . 1b and 1c It can be seen that the multimedia socket 100 includes an input port 110a and an output port 110b. The input and output terminal devices 110a, 110b are configured to that on this connection cable 200a, 200b ( FIGS. 3a to 3e ), which can be connected to the FIGS. 1a to 1c are not shown.

From the FIGS. 3a to 3e It can be seen that the connection cables 200a, 200b used in this embodiment are coaxial cables comprising an inner conductor 202a, 202b and an outer conductor 204a, 204b. The connection cables 200a, 200b are enclosed by an outer insulation 206a, 206b, which can be separated from the outer conductor 204a, 204b, so that the respective outer conductors 204a, 204b can be exposed. Also, the respective inner conductors 202a, 202b can be exposed by a corresponding insulation layer, so that they protrude from the end face of the respective connection cables 200a, 200b.

The input connection device 110a and the output connection device 110b are formed by an outer conductor contact device 112a, 112b configured as a cable bed 112a, 112b and by an inner conductor contact device 114a, 114b configured as a spring force device 114a, 114b. The inner conductor contactors 114a, 114b are in FIG FIG. 2 and will be described in detail below. The multimedia socket 100 comprises a cable connection space 112 in which the outer conductor contact devices 112a, 112b are formed. The outer conductor contact devices 112a, 112b are provided with transverse ribs 113, wherein in the region of the transverse ribs 113, the corresponding remote and exposed end regions of the outer conductors 204a, 204b of the coaxial cable 200a, 200b and thereby be contacted with the electrically conductive housing 102.

Out Figure 3c It can be seen that the front-side projecting inner conductors 202a, 202b protrude into the corresponding inner conductor contact devices 114a, 114b. The structure for the input cable 200a and the output cable 200b are designed accordingly.

The in the FIGS. 1a . 1b and 3a . 3c The inner conductor contact device 114a arranged on the left forms, with the outer conductor contact device 112a in front of it, the input connection device 110a, whereas those in the FIGS FIGS. 1a . 1b and 3a . 3c On the right, inner conductor contact device 114b with the outer conductor contact device 112b in front of it forms the output connection device 110b.

The cable connection space 112 formed in this way can be closed in a high-frequency-tight manner by folding over a closure flap 150, wherein the closure flap 150 is advantageously held pivotably on the housing 102 of the multimedia outlet 100 via a plastic strap 152. In this case, the end flap 150 also includes transverse ribs 151, which can be brought into contact with the corresponding outer conductors 204a, 204b and with the connection cables 200a, 200b when the end flap 150 is folded or closed. The end flap 150 can by means of a screw 153 (see FIG. 3e ) are connected to the housing 102, in which case the connection cables 200a, 200b are clamped in the cable connection space 112. The transverse ribs of the housing 102 and the end flap 150 are so formed so that they partially notched into the respective outer sheath of the connection cable, whereby a strain relief of the connection cable is ensured.

From the FIGS. 1a to 1c It can be seen that the multimedia socket 100 includes an insulating housing 120 disposed in the cable compartment 112. In FIG. 2 the insulating housing 120 is shown enlarged without the housing 102. The insulating housing 120 is closed at the rear by an insulating housing rear wall 121. In the insulating housing 120, the two spring sleeves 114a, 114b are arranged, which form the inner conductor contact means 114a, 114b. In the assembled state, the spring force devices 114a, 114b designed as spring sleeves are held and fixed in the insulating housing 120.

The structure of the spring sleeve 114a will be described below by way of example, wherein the spring sleeve 114b is constructed identically. The spring sleeve 114a in the illustrated embodiment has a hyperboloid-like shape and, in this embodiment, comprises four spring sleeve segments 114-1 to 114-4, each of which is formed by gaps 115-1 to 115-4 extending in the axial direction and over at least a partial length of the spring sleeve 114a are separated from each other. More specifically, the spring sleeve segments 114-1 and 114-2 are separated from each other by the gap 115-1. The spring sleeve segments 114-2 and 114-3 are separated by the gap 115-2. The spring sleeve segments 114-3 and 114-4 are separated by the gap 115-3 and the spring sleeve segments 114-4 and 114-1 are separated by the gap 115-4.

The spring sleeve 114a has a circular insertion opening 117a, via which a contacting space 116a limited by the spring sleeve segments 114-1 to 114-4 is accessible.

Due to the hyperboloid-like shape of the spring sleeve 114a, the inner cross section of the contacting space 116a tapers in a funnel shape from the insertion opening 117a in the axial direction of the spring force device 114a. In this case, the inner cross section of the insertion opening tapers in the axial direction of the spring sleeve 114a to a minimum cross section in the middle of the spring sleeve 114a and then increases again in the axial direction of the insertion opening 117a away. The taper of the inner cross section may be funnel-shaped.

The respective widths of the gaps 115-1 to 115-4 extending transversely to the axial direction of the spring sleeve 114a can be increased by inserting the inner conductor 202a through the insertion opening 117a into the contacting space 116a, wherein an inner conductor 202a introduced into the contacting space 116a is radial through the spring sleeve 114a is charged with force. Consequently, the inner conductor 202a in the contacting space 116a in the in FIG. 2 illustrated embodiment at four contact points or contact areas with the spring sleeve 114 in contact. In a correspondingly different number of spring sleeve segments, the spring sleeve 114 would be in contact with a correspondingly different number of contact points or contact areas with the inner conductor 202a.

The spring force device 114a comprises a contact pin 118a with which it is galvanically connected. This contact pin 118a is used for the electrical connection of the spring sleeve 114a, for example, with a printed circuit board 162. In the exemplary embodiment, the spring force device 114a and contact pin or contact element 118a are integrally formed.

In other words, therefore, the spring sleeve 114 is constructed so that the insertion openings 117a and 117b, which are offset in the axial longitudinal direction of the spring sleeve 114a to each other, are formed as a frame or ring or the like, for example, preferably in the manner of a regular n-polygonal. Between these two annular or frame-shaped insertion openings 117a, 117b, which are arranged concentrically by a spring sleeve 114a passing through the longitudinal axis extending through the mentioned columns separated spring sleeve segments 114-1 to 114-4, which ultimately web-like or web-like, ie z , B. band or strip-shaped. Furthermore, these spring sleeve segments 114-1 to 114-4 with a convex in the direction of the spring sleeve in the longitudinal direction passing through the central axis designed bulging, so preferably protrude with its central portion bulge or convex in the direction of the central axis, so that the interior space or distance space in particular two or more such spring sleeve segments is smaller than the outer diameter, that is smaller than the diameter of an inner conductor 202a to 202b to be introduced here. This results in the insertion of an inner conductor 202a, 202b to the elastic deformation of the spring sleeve segments, which are bent away in this case by the spring sleeve 114a passing through the central axis, whereby their convex inwardly projecting portion subjected to force and elastically rests on the outer circumference of the inserted inner conductor.

The Isoliergehauseückwand 121 comprises two projecting into the interior of the insulating housing 120 projections 121a, 121b, by means of which the contact pins 118a, 118b of the spring sleeves 114a, 114b are held and fixed in the interior of the insulating housing 120. The projections 121a, 121b can also be designed and dimensioned such that they close the opening of the spring sleeve 114a, 114b opposite the insertion opening 117a, 117b so that an inner conductor 202a introduced into the contacting space 116a can not protrude therefrom.

The insulating housing 120 has two access openings 122a, 122b, and the spring sleeves 114a, 114b are arranged inside the insulating housing 120 such that the inner conductors 202a, 202b pass through the access openings 122a, 122b and through the insertion openings 117a, 117b into the contacting spaces 116a, 116b can be introduced. For this purpose, preferably the centers of the access openings 122a, 122b and the insertion openings 117a, 117b are arranged collinear with one another. As already described, the insulating housing 120 and the Isoliergehiereückwand 120 are electrically non-conductive, so that transmitted via the inner conductor 202 a, 202 b signals are not transmitted to the housing 102 of the multimedia can 100.

The access openings 122a and 122b protrude from the region of the housing 102 accommodating the insulating housing 120, thereby precluding a short circuit between the housing 102 and the cable inner conductor 202.

From the FIGS. 1c and 3c It can be seen that the multimedia socket 100 comprises a high-frequency-density circuit space 160. For this purpose, the housing 102 comprises a base plate 107 delimiting the circuit space 160. The rear side of the multimedia socket 100 is closed by means of a cover 170. This cover 170 is either made of metal or is metallized, so that between the lid 170 and the bottom plate 107 of the high-frequency circuit space 160 is formed. In the high-frequency circuit space 160, a printed circuit board 162 is arranged, which is protected due to the shielding by the bottom plate 107 and the cover 170 from external electromagnetic radiation and at the same time can send no interference radiation to the outside.

From the FIGS. 1c and 3c It can be seen that the spring sleeves 114a, 114b are electrically connected by means of the contact pins 118a, 118b to the printed circuit board 162 for the exchange of data or signals. In this case, the contact pins 118a, 118b protrude from openings of the insulating housing 120 and through an opening 108 of the bottom plate 107 (see FIG 3d figure ). The axial direction of the spring sleeves 114a, 114b is aligned parallel to the printed circuit board 162 and the bottom plate 107, and the contact pins 118a, 118b are perpendicular to both the printed circuit board 162nd and also aligned with the axial direction of the respective spring sleeve 114a, 114b.

Since the spring sleeves 114a and 114b are rotationally symmetrical and have only a slightly larger diameter than the inner conductors 202a and 202b, with a multimedia socket 100 according to the invention, the characteristic impedance of the coaxial lines can be maintained up to the printed circuit board and so a low-loss signal transmission can be realized.

3d figure shows a perspective view of the multimedia box 100 from the bottom, with removed shielding housing cover 170 and without circuit board 162, so that in the lower circuit space 160, the opening 108 of the bottom plate 107 and projecting through the opening 108 through contact pins 118a, 118b the spring sleeves 114a, 114b are visible. As already mentioned above, these contact pins 118a, 118b with the in 3d figure not shown printed circuit board 162 electrically connected.

FIG. 3e shows the multimedia socket 100 according to the invention, wherein the cable connection space 112 is closed by the end cover 150 is fastened by means of the screw 153 to the housing 102 of the multimedia socket 100, so that the connection cables 200a, 200b and the corresponding outer conductors 204a, 204b contacted by the respective transverse ribs 113 and 151 and held under pressure.

FIG. 4 shows an alternative embodiment of the multimedia box 100 according to the invention, which differs from that with reference to the FIGS. 1a to 3e described multimedia box characterized in that the end flap 150 and the Schirmungsdeckel 150 is formed reduced in size. The reduced Schirmungsdeckel 150 ranges in the in FIG. 4 illustrated variant of the multimedia socket 100, since the housing tower for the insulating part of the insulating 120 consists entirely of a metallic or metallized material, so that the inner conductor contact means 114a, 114b are electromagnetically shielded.

FIG. 5 shows a perspective view of the housing 102 of another alternative embodiment of the multimedia box 100 according to the invention with the housing 102 is a Isoliergehäusewandung 123 of the insulating 120 is firmly connected and can be prepared for example in a common casting process. In the bottom plate 107, two openings 108 for the contact pins 118a, 118b of the spring sleeves 114a, 114b are provided.

FIG. 6a shows a multimedia box 100, which includes the housing 102 shown in Figure 5. The insulating housing 120, which is formed of an electrically insulating material is placed on the Isoliergehäusewandung 123 from the cable connection side. The rest of the construction in the FIGS. 6a to 6c shown multimedia box 100, is identical to the structure of the in the FIGS. 1a to 3e illustrated multimedia box 100th

FIG. 7 shows one opposite to in the FIGS. 1a to 1c shown multimedia box modified embodiment, with arranged above the contact areas housing openings 103a, 103b. These housing openings 103a, 103b are dimensioned so small that the shielding effect of the housing against electromagnetic radiation is not impaired.

The insulating part 120 is made transparent. As a result, the installer can see the actual inner conductor contact point and has a visual control option, whether the inner conductor is contacted correctly.

In the multimedia box 100 according to the present invention, it is not necessary to use an operating tool for assembling or disassembling a coaxial cable inner conductor 202a, 202b. Furthermore, the inner conductor 202a, 202b is not deformed or notched during assembly. A plurality of contact points or contact areas of the spring sleeves 114a, 114b distributed on the circumference of the inner conductor 202a, 202b ensure reproducible and low-loss electrical contact conditions even with large cable insulation tolerances, since the inner conductor end does not protrude beyond the spring sleeves 114a, 114b, but rather in the contacting space 116a , 116b remains. Therefore, the inner conductor 202a, 202b can further protrude into the spring sleeve 114a, 114b, whereby a high contact reliability between the inner conductor 202a, 202b and the inner conductor contact means 114a, 114b is given, even if the inner conductor 202a, 202 during installation of the multimedia socket 100 undergoes a tensile load in a flush-mounted box or in the case of length changes of the inner conductor 202a, 202b due to temperature fluctuations. In the embodiments, multimedia cans are shown having an input terminal 110a and an output terminal 110b. However, multimedia doses according to the invention can also be equipped with a plurality of input and output connection devices 110a, 110b.
