Connection socket for data network

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a data network connection socket comprising a metal bottom of a housing having a base for mounting and mounting on a wall, a metal upper part of a housing and a closed connection plate supporting at least one data socket. and a plurality of connection terminals for connecting the individual wires of the multi-core data cable.

BACKGROUND OF THE INVENTION

Such connection sockets are mounted so that they adjoin the wall, which may be both the building wall and the outer wall of the cable duct. The multicore data cable is installed either in the wall or in the cable duct, or it is fixed to the wall so that it lies on the outside and is therefore a so-called plaster installation. When installing the connection socket, the individual loose conductors must be connected to the connection terminals and the shielding of the data cable must also be electrically connected to the ground connection or the wiring board surface. When preparing this connection, the end of the data cable is first stripped of the external insulation so that the shield is exposed. Thereafter, the exposed screen is partially removed so that the fan wires can expand the individual cores of the data cable. In the known connection sockets, the exposed shield is connected directly to the ground surface of the connection plate. The location of the connection point and the method of routing the individual wires to the connection terminals make the connection board to be held in the palm of the hand for at least part of the electrical connection time. The connection socket can only be attached to the wall after the electrical connection and assembly of the metal parts of the connection socket. Finally, the top cover made of plastic is usually placed on the metal cover of the connection socket.

It is difficult to achieve a clean flow and continuity of the data cable with fast assembly. Also, the data cable is often sharply bent several times inside the top cover, depending on where the data cable is connected to the connection socket. The installation is particularly unfavorable if the incoming and routed data cable is to be connected.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the design of the connection socket of the type mentioned above, so as to allow its fast, clean and simple installation and to fulfill perfectly the conditions for perfect signal transmission.

SUMMARY OF THE INVENTION

The problem is solved and the drawbacks of the known data network connection sockets of this kind are largely eliminated by the data network connection socket, which consists of a metal bottom part of the housing having a support and wall mounting surface, a metal top part of the housing and between the bottom part. and a top part of the enclosed wiring board carrying at least one data socket and a plurality of connection terminals for connecting the individual cores of a multi-core data cable according to the invention, characterized in that on a base surface opposite the upper side of the bottom wall of the bottom part the contact plate is spaced substantially parallel to the upper side of the bottom wall of the lower part of the housing and the connection terminals are arranged on the upper side of the connection board facing away from the upper side any of the lower walls in proximity of at least one passageway in this connection plate, wherein the individual cores protruding from the data cable, which is secured by its shielding to the contact base, reach through the passages to the connection terminals.

The exposed cable end of the data cable is fixed in electrical contact to the contact base of the lower part of the housing, which in addition can already be mounted on a wall, such as a building. The end of the data cable is thus fixed in the correct position of the lower part of the housing and thus, without affecting later assembly operations, the data cable can be laid neatly. After the end of the data cable end, the individual cores of the data cable can be easily bent upwards, and after insertion of the wiring board on the lower part of the housing, the passages in the wiring board can be passed through. The ends of the individual cores can then be connected to the connection terminals with both hands. The lengths of the individual unshielded cores are really short, minimizing the loss and distortion of the data signal transmission. Finally, the metal upper part of the cover and, as usual, the top cover of plastic are also fitted.

It is advantageous if the bearing base is provided with a contact surface for shielding the data cable, which rises obliquely from the upper side of the lower wall of the lower part of the housing towards the connection plate. This ensures a gentle placement of the data cable, especially if it protrudes from a wall, such as a building.

Another advantageous embodiment of the connection socket according to the invention is that the lower part of the housing is at least approximately mirror-symmetrical to the plane of symmetry of the housing which is perpendicular to the base surface, with a bearing surface formed on each side of the plane of symmetry. This solution allows for the trouble-free installation of two data cables coming from the same main direction.

A further advantageous improvement of the connection socket according to the invention is that on each side of the plane of symmetry of the housing there are two roof-shaped contact surfaces facing each other. This solution allows for the trouble-free installation of two data cables coming from opposite directions.

In all these cases, it is advantageous if the bearing surface of the bearing base has a groove shape, the longitudinal axes of the grooves being parallel to the plane of symmetry of the housing, allowing easier orientation and gentle clamping of the ends of the data cables.

Furthermore, it is advantageous if threaded holes are provided between the abutment faces opposite to the plane of symmetry, which allows an easily accessible and stable anchoring of the clamping screws.

A further advantageous improvement of the connection socket according to the invention is that a metal bridge protrudes from the bearing base towards the connection plate, which in the assembled state of the connection socket biases against the ground surface of the connection plate, thereby ensuring a very short and reliable ground connection.

From the point of view of the individual conductors of the data cables, it is furthermore advantageous if two passageways are provided in the wiring board, which are located on both sides of the plane of symmetry of the housing in the embedded position of the wiring board.

The use of the connection socket according to the invention is further extended by the provision that at least one removable area is provided in the lower wall of the lower part of the housing for selectively creating a passage for the data cable.

Finally, to facilitate the installation of the connection socket according to the invention, there is provided in the lower wall of the lower part of the housing there are fastening holes for fixing screws for fixing the lower part of the housing to a wall of a building, for example, the lower part of the housing is provided with spacers. a connecting plate abuts a distance from the upper side of the bottom wall and an internal thread for the threaded shank of the clamping screw is formed in this lower part of the housing, whose head bears on the upper part of the housing.

DETAILED DESCRIPTION OF THE INVENTION

The connection socket according to FIGS. 1 and 2 consists of a metal lower part 11 of the housing, a connection plate 12 and a metal upper part 13. There is not shown a plastic top cover which overlaps all said components, since this top cover is known per se. The wiring board 12 is a multi-layer board with two outer conductive surfaces at ground potential. The intermediate layer is formed by insulated wiring, which in a known manner establish electrical connections between the individual terminals 14 for the wires and contacts of the module sockets 15. It will be understood that other types of data sockets may be used instead of the illustrated module sockets 15.

According to FIGS. 2 and 3, the lower housing part 11 comprises a lower wall 16 with a substantially flat base surface 17 opposite the upper side 18 of the lower wall 16. The lower housing part 11 is further provided with two side walls 21, 22 which are arranged on opposite sides of the symmetry plane 19 of the cover.

In plan view, the lower housing part 11 is approximately T-shaped, as shown by the fact that the engaging plate 12 engaging in this lower housing part 11 is somewhat wider in the region of the wire connection terminals 14 than in the area of the module sockets 15. Bottom wall 16 2 and 3 on the right, extending beyond the side walls 21, 22, as a result of the fact that the two attachment openings 23, 24, which serve to secure the lower housing part 11 to a wall (not shown) by means of attachment screws (not shown), have normalized spacing which is greater than the required length of the lower housing part 11 itself.

Approximately a quarter of the length is formed in the lower wall 16 by a cap-like abutment 25 whose upper edge 26 is oriented parallel to the base surface 17 and perpendicular to the plane of symmetry 19 of the housing. On one side of the symmetry plane 19, two groove-shaped bearing surfaces 27, 28 are formed in the abutment base 25, the longitudinal axes of which adjoin one another and are parallel to the symmetry plane 19. The two bearing surfaces 27, 28 rise at an angle of approximately 30 ° from the upper side 18 of the bottom wall 16 against each other up to the common upper edge 26. On the opposite side of the symmetry plane 19, corresponding bearing surfaces 29, 3.0 are formed according to the principle of symmetry. A threaded bore 32 is formed between the bearing surfaces 27 and 29 in relation to the plane of symmetry. an intermediate surface 33, in which a further threaded hole 34 is formed. These threaded holes 32, 34 can be screwed with individual screws (not shown), by means of which the clamping bracket 35 shown in FIG. cable 36.

The position of the data cable 36 is shown in broken lines in FIG. While, except for the shield 37, the exposed end of the data cable 36 is pulled by the clamping bracket 35 to the bearing surface 27, another area of the data cable 36 is fastened in a manner not shown by a generally known cable tie to the thumb 38. 16. Corresponding fingers 39, 41 and 42 are also provided at other corresponding locations of the bottom wall 16, so that a total of four data cables can be attached to the bottom part 11 of the housing by analogy. In practice, however, a maximum of two data cables 36 are generally connected, but they can be arranged in different orientations. In particular, the main direction 43 and the opposite direction 44, which are parallel to the symmetry plane 19 of the housing, are indicated by arrows in FIG. The data cable 36 may be mounted on one side of the symmetry plane 19 from the main direction 43, and another, not shown data cable, may also be arranged from the main direction 43 on or on the opposite side of the symmetry plane 19, but from the opposite main direction 44. the cables 36, which are fed from the two main directions 43, 44 to the lower part 11 of the housing, do not need to bend sharply up to the point of attachment to the abutment base 25. Of course, the data cable 36 may be bent to one side as desired upon attachment to one of the fingers 38, 39, 41, 42, which bending may be performed with a sufficiently large bending radius.

Another possibility of introducing the data cable 36 is shown in FIG. 2, where two removable areas 45, 46 of approximately circular shape are formed in the lower wall 16 by breaking connections. If necessary, holes can be provided in the bottom wall 16 without the use of special tools, by means of which data cables 36 can be introduced into the interior of the connection socket, which are housed in the wall or in the cable duct.

The connection plate 12 must be placed at the bottom 11 of the housing at a certain distance from the upper side 18 of the bottom wall 16 of the lower housing part 11, thereby providing the necessary space for the data cables 36 attached to the lower housing part 11. This distance is defined by spacers which are formed by the edge surfaces 47, 48 of the side walls 21, 22 and the annular surface 49 of the pin 51 that extends from the upper side 18 of the bottom wall 16. This pin 51 is also provided with an internal thread 52. A metal bridge 53 extends upwardly from the center of the bearing base 25, slightly higher than the spacing defined by the spacers already described. If the engagement plate 12 is then mounted on said spacers, the leading edge 54 of the bridge 53 urges at this point the exposed area of the ground surface on the engagement plate 12, which is consequently slightly bent upwards. This ensures direct and reliable grounding.

Guide grooves 55, 56, 57 and 58 are formed in the end regions of the side walls 21, 22, into which metal cross plates (not shown) can be inserted if necessary.

FIG. 1 illustrates several individual cores 59 of the data cable 36 that extend upwardly to the wiring board 12, pass through one of the two passages 61, 62 in the wiring board 12 and then electrically connect to the respective wiring terminals 14 Thus, the individual cores 59 do not bend over the edge of the engagement plate 12 but extend through the engagement plate 12 near its central region. Since the wiring terminals 14 are arranged on the top of the wiring board 12, the individual wires 5 9 can also be connected in a predefined built-in position of the wiring board 12 on the lower housing part 11, which itself is firmly screwed to the wall, e.g. . After the electrical connections have been made, the upper part 13 of the cover is mounted and fastened to the lower part 11 by means of a screw (not shown), the shank of which is screwed into an internal thread 52 in the pin 51 and whose head abuts the abutment surface 63 on the upper part 13 of the cover. By pulling the lower part 11 and the upper part 13 of the cover together, the wiring board 12 clamped between them is fixed, which is biased against the bridge 53. It is understood that through holes 64, 65 are formed in the upper housing part 13 through which the inlet openings of the module sockets 15 are accessible. Finally, a threaded sleeve 66 is disposed on the upper side of the upper housing part 13 into which a screwing screw (not shown) can be screwed. attachment of a plastic cover (not shown).

Modifications deviating from the described embodiment can be made, for example, in that the bearing surfaces 27, 28, 29, 30 are flat and are inclined in the shape of a canopy, or are also parallel to the base surface 17. The inclination in the shape of a canopy shown in the exemplary embodiment, it has the advantage, inter alia, that the axes of the threaded holes 32, 34 are inclined relative to the base surface

17. The clamping screw that is oblique to the wall can be attracted to a greater extent without hitting the wall so that the same clamping screw can pull data cables 36 with more different diameters.
