The outlet plug connector is attached to the cover, together with the outlet cover 8, by means of integrally formed elastic latching means. The cover can be fitted to the mounting frame 4 by means of screws. <IMAGE>

Description

AT 407 808 B

The invention relates to a kit for a data transmission outlet for the electrical connection between an electrical data transmission cable and an external connector, the outlet kit having a connector module which has an outlet connector housing, a connector insert for the electrical connection to the external connector and a connector for the electrical Has connection between the connector insert and the cable, of which the connector insert and the connector can be mounted on the outlet connector housing, in particular a kit with a housing made of a one-piece part, which can be broken down into individual housing components for assembly by breaking.

The need for flexible wiring and provision for future applications has become increasingly important in the construction industry. In order to adapt to the rapidly changing technology and also for example with regard to the future growth of a company and its requirements for data transmission possibilities, it is desirable that the data transmission connections between the different rooms of a building can be quickly converted to a new wiring system. If the requirements for data transmission have increased in the past, special cables have often been laid inside the building, which is very expensive, however, and the addition of wires in bulk means increased repair and maintenance times, which also necessitated the use of specialists.

In order to counter these problems, the cabling concept for data processing has been redesigned into a more flexible system, as is shown, for example, in WO 87/07775, according to which multi-purpose data transmission cables (which, for example, in addition to the usual insulated electrically conductive wires, data and / or telephone cables included) are distributed over the entire building, and these cables are connected to the data transmission outlet. These outlets are designed in such a way that there is an insert which establishes the data transmission connection between a connector box mounted on a wall, on the floor or another part of the building, which is connected to the cable, and a user connector, which for example is a portable one Device is connected. If this portable device is to be removed and replaced with another device which, however, requires a different data transmission connection, the insert is quickly removed from the connector box and replaced with another insert which is suitable for receiving the plug of the new device.

Therefore, depending on customer needs, the inserts are usually offered separately from the outlet connector box.

This outlet connector box is separately mounted on a building part, and it is desirable to have an outlet connector that can be installed in many different types of building parts, such as a wall, floor, or cable duct, to accommodate as many as possible with just one set of parts Needs to be taken into account.

In addition, it is desirable to offer assembly kits that contain as few loose parts as possible because this reduces inventory handling and handling costs.

In order for the fixed outlet connector to be installable in many different installation locations, it is often necessary that the required installation depth within the installation location for this connector is quite small, although it is desirable that the outside part of the outlet connector does not protrude far, otherwise that will be the case The risk of personal injury or, for example, moving furniture is very high.

It is also desirable to have quick access to the outlet connector so that the insert can be removed quickly, or changes or repairs to the outlet connector box can be made.

DE 12 50 908 B shows a built-in housing for prefabricated construction parts, which has a square lower part and an annular upper part. The upper part is equipped with a removable cover, which is glued to the bottom of a casting mold (e.g. for concrete) using an adhesive layer arrangement. From this one can derive the general technical teaching to attach certain areas of cast-in installation boxes, which are no longer required after casting, through thin predetermined breaking points on the housing, so that they can be easily separated after the actual component has been cast. With regard to the problems mentioned above with data transmission devices in a building, however, this document can be 2

AT 407 808 B does not take any specific suggestion.

From DE 29 13 038 a connector arrangement is known in which a strain relief element in the form of transverse ribs is arranged in the vicinity of the outlet side of the housing of the connector arrangement. Another strain relief element is integrally formed on the housing cover via a film hinge. This can either be folded inwards for use or torn off. The present invention is generally concerned with providing a data transfer outlet kit as an interface between an electrical data transfer cable and an external connector, the specific design of the connector and data transfer cable when mounting the outlet kit may not be known. From DE 31 06 492 a screwless fastening of socket inserts via pins / pin receiving holes is known.

The object of the invention is therefore to provide a data transmission Ausiaßausbau which contains few parts and which is inexpensive to manufacture, handle and assemble.

This object is achieved according to the invention by a data transmission outlet kit for the connection between an electrical data transmission cable of the known type, which is characterized in that the connector housing is a one-piece part which can be separated by breaking it into individual housing components for the assembly of the connector module, for example in a case and a lid.

Embodiments of the invention are specified in the dependent claims.

The preferred embodiment of the invention will now be described in detail with reference to the accompanying drawing figures. Show it:

Referring first to FIG. 1, a data transfer outlet kit shown at 2 includes a mounting frame 4, a data transfer outlet connector module, generally designated 6 in separate components, and an exhaust cover shown generally at 8. The data transfer outlet connector module 6 is shown to include a one-piece data transfer connector 10, an outlet connector housing 12, and a data transfer connector insert 14.

Referring now to FIG. 2, the outlet connector 3 is shown to include

AT 407 808 B housing 12 an outlet housing box 16, an outlet housing cover 18 and a shielding strain relief device 20th

3, the outlet connector housing will now be described in detail. Before assembly, in the preferred embodiment, the outlet connector housing 12 is a one-piece injection molded plastic part in which the housing box 16 and the housing box cover 18 are fastened to one another via thin breakable straps 22, the strain relief device 20 being molded onto the housing cover 18 by means of thin straps. There are two strain relief devices attached to the outlet housing cover 18, a strain relief device 24 of small diameter and a strain relief device 26 of large diameter. The strain relief devices have a rectangular prismatic block 28, a cylindrically shaped recess 30 for the adjacent reception of a cable and smooth-walled cylindrical bores 32 for receiving self-tapping screws on each side of the recess 30. On the side facing away from the recess 30 and the bores 32 for self-tapping screws The strain relief device 24 has a pair of frustoconical provisional bearing holes 34, which can best be seen in the partially broken view of the strain relief device 24 in FIG. 3. It is understood that the strain relief device 26 has similar frustoconical bearing holes 34.

Still referring to FIG. 3, as shown, the covers 18 have a main cover base 36, also a short cross cover section 38 along a bottom edge 39 of the main cover base 36, elastic locking pawls 40 and provisional strain relief bearing journals 42. On an upper edge 41 of the cover 18 there is a protrusion 44 on an outside of the lid, as shown in FIG. 4.

3 and 4, the outlet housing box 16 has an upper wall 50, an opposite side bottom wall 52 and adjacent side walls 54, 56. The four walls 50, 52, 54, 56 define a front cavity portion 58 for receiving the connector insert 14, one rear upper cavity section 60 for receiving the internal connector 10, and a rear cavity section 62 for receiving a data transmission cable 64. In addition, there is a receiving cavity 63 for a strain relief device within the cavity section 62. In the interior of the outlet housing box 16, a structural wall 66 is attached to the bottom wall 52 for separating the first and third cavity sections and projects from the bottom wall transversely to the middle height between the upper and lower walls 50, 52. On the upper edge of the building wall 66 there is a dividing wall 68 which extends transversely to the rear and separates the second cavity section 60 from the third cavity section 62. Both walls 66 and 68 extend substantially from one side wall 54 to the other side wall 56. The building wall 66 has screw positioning holes 70 therein for receiving strain relief tapping screws 72. On the top wall 50 between the first and second cavity sections 58, 60 there is a low rib 74 transverse to the side walls 54 and 56. On the side walls 54, 56 there are catch recesses 76 in the first cavity section 58 (FIG. 3). On an upper edge of the building wall 66 there is a beveled control surface 67 for engagement with locking means.

Referring again to FIG. 1, the connector insert 14 includes, as shown, a printed circuit board 80 with electrical traces formed thereon, a connector socket member 82, a cover plate 84 and, attached thereto, locking hooks 86. It can be seen that in FIG Telephone connectors are shown, but any form of connector is available, including data, coaxial, optical, etc.

According to FIGS. 5a and 5b, a typical data transmission cable 64 has, as shown, an insulating jacket 87, an outer shield 88, a drain wire 89 and inherently insulated lead wires 90. The cables 64 are typically prepared in such a way that the drain wire is laid against the insulating jacket 87 ( Fig. 5A) and then the shield 88 is placed backwards over the drain wire and the insulating jacket 87.

According to FIGS. 6a to 6d, the plug connector 10 has a cover 92, a housing 94 and insulation displacement connecting sleeves 96 as shown. The housing 94 has a receiving slot for a printed circuit board, the slot extending rearward from a front abutment surface 100 past contact contacts (not shown) which are electrically connected to the connector sleeves 96. The cover 92 has a row of cylindrical 4

AT 407 808 B shear recesses 102 for receiving the sleeves 96, wherein the recesses 102 have longitudinally extending wire receiving slots 104 which extend from the abutment surface 103 of the recess 102 to a filler bridge section 106.

The assembly of the data transmission connector 6 from the various kit parts is explained below. Referring first to FIG. 5, the preparation of a shielded data transmission cable 64 is shown. A portion of the outer jacket 87 must first be removed as shown in Figure 5a, and then the shield 86 must be pulled back over the jacket 87 to expose the individual insulated lead wires 90 along the portion where the jacket 87 has been removed.

6a, the lead wires 90 must then be separated such that they can be pushed individually into the wire receiving slots 104 of the cover 92, and according to FIG. 6b the wire end abuts on the side of the recess 102 opposite the wire receiving slot. As shown in Fig. 6b, resilient clips 107 temporarily hold the wires 90 on the cover 92. Once all of the wires 90 have been inserted into the associated slots and recesses 104, 102, the cover can then be aligned with the housing 94 in such a way that the Connection sleeves 96 are inserted into the recesses 102. When the cover 92 and housing 94 are crimped together, the slots in the insulation displacement connector sleeves 96 cut through the insulation and come into electrical contact with the wires 90, similar to the previously known insulation cutting clip technique. A specially designed pair of pliers 110, as shown in FIG. 6d, can be used to provide the necessary cable connection force.

7, the connected connector 10 can then be fully inserted into the second rear cavity section 60 of the outlet housing box 10 until the latching element 99 engages with the upper edge 69 of the inner structural wall 66 (see FIG. 4) to hold the connector 10 in the outlet housing box 16. As can also be seen in FIG. 4, the oblique control surface 67 of the building wall 66 serves to elastically prestress the locking element 99 via the upper edge 69 of the building wall.

8, the outlet housing cover 12 can then be separated from the outlet housing box 16 by breaking off the thin strips 22 from the housing 16 and from the cover 12. The plastic of the housing kit has a certain elasticity so that the straps 22 do not break during handling and during transport, which elasticity is also required to elastically pretension the locking pawls 40, but the material also has to be relatively brittle so that one can press the tapes 22 at connection points between the housing and the cover in such a way that a clean separation takes place. In addition, the cross section of the band, where it adjoins the housing or the cover, can be reduced in such a way that breakage is favored along this reduced connection cross section.

To hold the shield properly and prevent the braided wires from fraying, a conductive copper foil 112 can be wrapped around the exposed, rear-folded cable shield as shown in FIG. 8.

9, the cable 64 can then be pivoted through 90 °, so that it runs through the slot 57 of the bottom wall 52. Then both strain relief devices 20 can be broken off from the cover 18, the strain relief device which has the correct recess size for the size of the cable 64 being selected and then pressed onto the provisional bearing journal 42 which engages with the provisional bearing holes 34 of the strain relief device occurs. Because of the tapering mating surfaces of pins and holes, the strain relief device 20 can be held on the pin 42 due to the wedge effect with the matching bearing holes 34. If a wedge is pressed into a corresponding receiving space with a certain force, the force component oriented perpendicular to the mating surfaces is very large if the taper angle is very small, which causes an (elastic) deformation of the material such that when the insertion force is applied is reduced to zero, this elastic compressive force exists and causes a frictional force between the wedge surface and the matching receiving space surface, in order in this way to hold the wedge on the receiving space walls. In this way, as stated above, the strain relief device 20 is held by friction on the bearing journal 42 of the cover, and the cover 18 can be closed over the rear section of the outlet housing box 16, whereby the cross cover section 38 5

AT 407 808 B of the cover is inserted into the slot 57 of the housing box 16 such that it essentially closes the slot opening around the cable 64.

A strip 43 closely adjacent to the edges of the cover serves to position the cover 18 with respect to the housing box 16. The elastic locking pawls 40 engage with notches (not shown) in the side walls 54, 56, around the cover 18 on the housing box 16 to hold, whereby the rear cavity portions 60, 62 of the outlet connector module are virtually closed from the environment. The strain relief 20 is positioned on the lid such that when the lid is locked to the housing box, the strain relief is inserted into the strain relief receptacle cavity 63 until the strain relief recess 30 is close to the cable 64 or this touches, in particular the folded shield part of the cable. As shown in FIG. 9, the cable 64 advantageously extends across the strain relief receiving cavity 63 and through the slot 57, thereby placing the shield against the trailing edge of the slot 57.

As already mentioned above, two different strain relief devices are provided on the cover, each strain relief device 20 having a recess 30 with a different recess diameter. Depending on the diameter of the cable 64, the strain relief device 20 with the recess 30 is selected which has the size most suitable for the cable diameter. Because the cable is deformable, each recess 30 of the strain relief device can be used for a range of cable diameters, for example the first strain relief device could be suitable for cable sizes of 5 to 8 mm in diameter, while the second strain relief device would be designed for cable sizes between 8 and 10 mm in diameter . This provides strain relief devices in connection with the outlet kit for cables, the size of which ranges from 5 to 10 mm in diameter.

It should be understood that in such an arrangement of the provisional trunnions 42, when the cover 18 is disposed over the back of the box 16, the strain relief device 24, 26 is inserted into the cavity 63, with the holes 32 having holes 70 in the structural wall 66 are aligned, cf. Fig. 4. If one now looks at the two FIGS. 4 and 10, self-tapping screws 72 are inserted through the holes 70 in the structural wall 66 until they abut the bores 32 of the strain relief device 20 which flanks the cable 64. In the preferred embodiment, the bores 62 have no thread, but rather are a smooth cylindrical wall surface with a diameter that is smaller than the outside diameter of the screw thread, so that the screws 72 "as thread" into the holes by cutting a screw turn into the plastic wall of the screw hole. Tightening the screw on each side of the cable pulls the strain relief device 24 or 26 against the shield away from the pin 42 and against the cable so that member 24 or 26 pinches the cable 64 between the strain relief device 20 and the structural wall 66 and holds on. In the preferred embodiment of the invention, the box 16 and the strain relief devices 24, 26 are conductive, preferably it is clad plastic, which forms a common earth with the shielding 88 of the cable.

11, the connector insert 14 can then be inserted into the front cavity portion 58 of the housing box 16, with the printed circuit board 80 inserted into the slot 98 of the connector 10 to make an electrical connection therewith. Conductor tracks (not shown) on the upper and lower surfaces of the board 80 lead to electrical contact with the connections of the connector 10. In the fully inserted state, the connector insert 14 is locked to the outlet housing box 16 by the locking hooks 86 of the connector insert, which are connected to the recesses 76 the case side walls 54 and 56 engage. The insert thus essentially closes the front cavity section 58 of the outlet housing box 16 from the surroundings. The connector socket part 82 is used for receiving and for the electrical connection to a plug 120, as shown in FIG. 4. Such an insert 14 can contain electronic circuit elements which handle the electrical data transmission between the cable 64 and the plug 120, the inserts simply by clipping the locking device 6

AT 407 808 B hook 86 according to FIG. 12 can be removed with the aid of a screwdriver in order to replace the insert 14 by another insert which either has a different electronic circuit or a different wiring arrangement, for example, or is suitable for other connector types. These inserts are already known and can be obtained from the applicant. If the 5 data transmission outlet connector module 6 is redundant and can be used for future applications, the connector insert 14 can be replaced by a dummy insert 122 (FIG. 11), which only serves as a cover for the front cavity portion of the housing box 16.

Therefore, the kit described in the present disclosure is advantageously 10 inexpensive to manufacture because the lid 18, strain relief device 20, and box 16 can be made as a one-piece plastic molding, which also has the advantage of providing extra handling, packaging, and packaging expense the storage of separate loose parts can be avoided, which is not only advantageous for the manufacturer, but also for the end user.

Another advantage is the presence of two strain relief devices that cover a large range of cable diameters.

The provisional bearing journals on the cover, which cooperate with bearing holes on the strain relief device, are also advantageous in order to enable a very simple and quick assembly of the strain relief device and cover. In addition, the self-tapping screws for fixing the strain relief device ensure a very secure clamping of the cable, while only smooth holes in the strain relief device are required, which are very easy to form.

In the assembled state of Fig. 12, the data transfer outlet connector 16 is ready to receive a connector 120 to provide an electrical connection between the connector 120 and the data transfer cable 64, however, the connector 25 module 6 is in one below described manner can be installed at an installation location.

13, an outlet cover 8 has a base plate 130 with a large center hole 131, and a pair of triangular side walls 134 are provided on opposite edges of the center hole 131 that protrude outwardly from the base plate 130. An end plate 132 extends between the mutually opposite upper edges 135 30 of the triangular side walls 134, the end plate 132 also connecting to an upper edge 137 of the base plate 130. The pair of spaced triangular side walls 134 and faceplate 132 define a half-boxed interior cavity 139 which is capable of receiving practically half of the communication outlet connector module 6, with the plane of the base plate 130 being approximately parallel to a diagonal which is a top 35 rear Corner 140 connects to a lower front corner 142 of the connector module. The side walls 134 and the end plate 132 thus define a triangular, projecting half-box bracket 136. Under the upper edge 137, an elastic locking projection 144 projects into the inner cavity 139, and on an opposite bottom edge 146 of the center hole 131 there is an oblique insertion projection 148, for example parallel to the end plate 132. The base plate 130 40 also has holes for receiving mounting screws 150.

13, the connector module 6 can be mounted on the outlet cover 8 by tilting the connector module according to FIG. 13b in such a way that the opposite corners 140, 142 are practically parallel to the base plate 130 in one plane, during the Connector insert facing the lid opening 133. The Dek-45 kelplatte 84 is inserted between the insertion projection 148 and the end plate 132 until the housing box projection 44 abuts the locking projection 144. By exerting a force on the connector module approximately perpendicularly in the direction of the base plate 130, the projection 144 is elastically stretched outward so that the projection 44 is inserted past it and engages behind it in the locked state, as shown in FIG. 13c or 50 Fig. 4 is shown.

The assembled connector module 6 and the outlet cover 8 are thus locked together and can be securely installed at the installation site using the screws 150. 14, the mounting frame 4 includes a metal frame 160 with a center hole 162 for receiving the lower rear triangle half-box of the connector module 6, elongated 55 mounting holes 164 with a portion 166 of large diameter and an adjacent 7th

Claims (13)

AT 407 808 B slot of smaller width, 168, and cover mounting threaded holes 170. The frame 4 can be mounted with the aid of screws 174 on a mounting component 172, 172 ', 172 &quot;, 172 "'. The large diameter section 166 of the mounting holes 164 has a diameter larger than the head of the screws 174 so that the screws can be loosely screwed into the mounting member 172 before the frame 4 is mounted thereon, followed by the enlarged sections 166 Align the frame with the screws 174 so that the frame can be inserted past them. Once the enlarged section 166 has passed the heads of the screws 174, the frame can then be rotated such that the threaded section of the screws 174 enters the slot 168, the slot 168 having a gap width which is smaller than the diameter of the screw heads. The screws 174 can therefore be tightened in order to securely fix the frame 4 to the mounting component 172. To the frame of the Mon-tagebautei! To solve 172, you only have to loosen the screws 174, turn the frame until the screw heads are aligned with the respective larger hole section 166, and pull off the frame. If the frame 4 is mounted on the mounting component 172, the outlet cover 8 and the connector module 6 can be securely attached to the frame 4 with the cover screws 150, the rear diagonal half of the connector module 6 protruding behind the frame 4 into a cavity which is located within the Mounting component 172 is located. FIGS. 14 to 17 show various options for mounting the outlet cover and connector module on different mounting components, FIG. 14 a flush-mounting mounting box 172, FIG. 15 a surface-mounting mounting box 172 ', FIG. 16 a cable duct part 172 &quot; and Fig. 17 shows a bottom part 172 '”. Advantageously, the diagonal arrangement of the connector module 6, which is mounted on the outlet cover 8, requires less installation depth behind the mounting frame 4 than an arrangement in which the connector module would be mounted so that it would stand perpendicularly from the base plate 130. Another advantage of the diagonal mounting position of the connector module 6 in connection with the smaller required depth is that the connector socket part 82 protrudes obliquely downwards in the case of mounting in a wall, because this arrangement protects an inserted connector 120 from objects or people who may unintentionally hit connector 120. An object that moves very close to the outlet cover 8 mounted on, for example, a building wall will in most cases hit the side walls 134 or the end plate 132 of the cover 8 and not the plug 120, the latter case very easily damaging the Plug 120 and insert 14 could result. Another advantage of this arrangement when installed in a building wall is that, due to the socket part 82 pointing downward, there is better protection against dust and liquids. An additional advantage of this arrangement is that it is also well suited for floor-mounted versions, the butt surface of the connector module still pointing obliquely upwards being usually a preferred position. It is also advantageous that the locking of the connector module on the outlet cover by means of the latching device 144, 140 and the subsequent mounting of the cover 8 on a mounting component 172 by means of the screws 150 means that the cover is easily unscrewed from the mounting component and the entire connector is removed the component can be pulled out, which allows quick and very good access to the connector module 6, so that repairs or changes such as an exchange of the insert 14 can be made easily.
