The invention relates to an insulation displacement plug-in connector for telecommunications and data technology, comprising a housing (45) and a number of contact elements (43), wherein the contact elements (43) each comprise an insulation displacement contact (54) for connecting cores and a pin contact (53) for making contact with a printed circuit board, wherein at least one extension (55) is arranged between the insulation displacement contact (54) and the pin contact (53).

Description

The invention relates to a insulation displacement connector and a device for telecommunications and data technology.

Such a insulation displacement connector is for example from the EP 0 766 352 B1 known. The insulation displacement connector comprises a housing in which contact elements are arranged, wherein the contact elements have a first contact region, which is designed as insulation displacement contact, and a second contact region, which is designed as a solderable contact pin (pin contact). The housing is formed in one piece and is soldered via the contact pins with the circuit board. The contact elements are inserted from the top of the housing and held by stops, wherein in the inserted state, the contact pins protrude from the bottom of the housing. For shielding Schirmungsbleche are provided which are inserted from the underside of the housing and are each arranged between two pairs of contact elements. The shield plates are also formed with contact pins, so that they can also be soldered to the circuit board and placed on a common ground line. Such modules are also referred to as PCB print modules. Via the trained as insulation displacement contacts contact areas wires can then be electrically connected to the circuit board.

A digital signal distributor DSX (Digital Cross-Connect System) provides a jumper connection between two digital transmission paths. The DSX device is usually located in racks, which are usually located in the switching center of a telephone service provider. The DSX device also provides jack access to the transmission paths.

DSX jacks are well known and typically include a plurality of holes sized to receive plugs. Within the holes a plurality of switches for contacting the plug is provided. The jacks are electrically connected to digital transmission lines and are also electrically connected to a plurality of terminal members which are used to maneuver the jacks. By inserting plugs into the holes in the sockets, signals transmitted via the sockets can be interrupted or monitored.

In the Fig.1 is one of the US 6,840,815 A prior art DSX system is shown schematically illustrating an example of a system to be found in a digital exchange of a telephone service provider. The DSX system is illustrated with three DSX sockets 10a, 10b and 10c. Each DSX socket 10a, 10b and 10c is connected to a specific part of the digital device. For example, the DSX socket 10a is connected to the digital switch 12, the DSX socket 10b is connected to the office amplifier 14a, and the DSX socket 10c is connected to the office amplifier 14b. Each digital device has an input at which a digital signal can enter, as well as an output at which the digital signal can exit. The DSX sockets 10a, 10b, and 10c each include OUT pins 16 and IN pins 18. The DSX sockets 10a, 10b, and 10c are connected to their respective digital devices by connecting the OUT pins 16 to the device (FIG. that is, going to the DSX system) and by connecting the IN pins 18 to the signals entering the device (ie, going out of the DSX system).

Still on Fig. 1 Referring to FIG. 12, the DSX sockets 10a and 10b are "cross-linked" by semi-permanent connections. The semi-permanent connections extend between patch panels 19 of the DSX jacks 10a and 10b. For example, patch cords connect 20 OUT jumper pins of the DSX jack 10a to IN jumper pins the DSX socket 10b. Similarly, patch cords 21 connect IN jumper pins of DSX jack 10a to OUT jumper pins of DSX jack 10b. The switches of the DSX sockets 10a and 10b are preferably closed. Thus, if no plug is plugged into one of the DSX jacks 10a and 10b, a connection is provided between the DSX jacks 10a and 10b and therefore between the digital switch 12 and the office amplifier 14a.

The semi-permanent connection between the digital switch 12 and the public office amplifier 14a may be interrupted for diagnostic purposes by plugging plugs into the IN or OUT terminals of the DSX jacks 10a and 10b. Similarly, patch cords may be used to break the semi-permanent connection between the DSX jacks 10a and 10b to provide connections to other digital devices. For example, the digital switch 12 may be disconnected from the trunk repeater 14a by use of the patch cords 23 and connected to the trunk repeater 14b. The patch cords 23 include plugs plugged into the IN and OUT ports of the DSX jack 10a and the IN and OUT ports of the DSX jack 10c. Plugging the plugs into the IN and OUT terminals of the DSX jack 10a will open the normally closed switches or contacts, breaking the electrical connection to the trunk repeater 14a and establishing an electrical connection with the trunk repeater 14b.

From the US 6,116,961 respectively. US-6,840,815 B2 In each case a digital signal distributor is known, which is modular. The modules each include a socket receptacle for receiving four DSX sockets and a printed circuit board. The female receptacle is connected via first contact elements with the circuit board, wherein parts of the contact elements protrude through openings of the female receptacle and contact them when inserting the DSX sockets. The printed circuit board is longer than the socket receptacle so that patching and device connection fields can be arranged underneath the socket receptacle. For this purpose, a cover part is applied to the circuit board at least from the side of the female receptacle. The cover part has openings into which Kotnaktelemente can be inserted. The contact elements have a pin contact for contacting the circuit board and a wire-wrap contact for connecting wires. Furthermore, both documents disclose to use insulation displacement contacts instead of the wire-wrap contacts.

A problem with the use of insulation displacement contacts as a replacement for the wire-wrap contacts is that they require more space. The reason for this is that the insulation displacement contacts must be connected with a special tool, for which a free accessibility is necessary.

document US 2003/0064611 discloses an insulation displacement connector according to the preamble of claim 1.

The invention is therefore based on the technical problem of providing an insulation displacement connector and a device equipped therewith for the telecommunication and data technology, by means of which a compact construction is made possible.

The solution of the technical problem results from the objects with the features of claims 1 and 9. Further advantageous embodiments of the invention will become apparent from the dependent claims.

For this purpose, an extension is arranged between the insulation displacement contact and the pin contact. This ensures that the insulation displacement contacts are guided away from the circuit board. However, this dimension is usually uncritical for the packing density. The extension is chosen such that the insulation displacement application tool is not obstructed by surrounding edges when wiring. Thus, a high contact density is maintained and exploited the known advantages of insulation displacement technology. In this case, insulation displacement contacts, extensions and pin contacts are preferably integrally formed.

In a preferred embodiment, a guide element is arranged on the underside of the insulation displacement contact, which is further preferably formed wider than the insulation displacement contact. One possible training is the shape of a rectangle. By the guide element, the introduction of the insulation displacement contacts in the housing is substantially improved, since the extension increases the elasticity of the contact element.

In a further preferred embodiment, two arcuate elements are arranged at the end of the extension associated with the pin contact. These are preferably arranged symmetrically about the extension, wherein more preferably, the two arcs are opposite to each other. The arcuate elements serve on the one hand to support the contact element in order to absorb the occurring Anschaltkräfte. Due to the arcuate design of the structure can also be chosen very compact beyond.

In a further preferred embodiment, the inner sides of the housing are formed with grooves for the guide elements, which extend from the underside of the housing to the upper side. Up to the top in this context is to be understood that the groove extends so far that parts of the insulation displacement contact are still in the groove.

In a further preferred embodiment, slots are made in the groove walls of the guide elements, wherein the length of the slots of the length of the elements of the arcuate. Corresponds to elements.

In a further preferred embodiment, a further extension is arranged between the arcuate elements and the pin contact. This extension corresponds to the thickness of a cover piece arranged on the printed circuit board.

In a further preferred embodiment locking lugs are arranged on the outer sides of the housing. By means of these locking lugs of the insulation displacement connector can be latched to the cover piece, which causes increased stability. For this purpose, the cover piece on a receptacle for the insulation displacement connector. The receptacle preferably has walls which define an open cuboid, wherein the walls have latching openings for the latching noses.

In a further preferred embodiment, the housing of the insulation displacement connector has slots for receiving the leads to be connected, wherein the insulation displacement contact is aligned at 45 ° to the slot. This will secure the vein contacted, wherein the diameter of the wire is reduced only slightly by the clamping.

A preferred application of the insulation displacement connector according to the invention is the use in a digital signal distributor.

The DSX module 34 includes a jack receptacle 35 for receiving a plurality of jacks 36, 38 (e.g., two odd-numbered jacks 36 and two even-numbered jacks 38). The DSX module 34 has a front-accessible patch panel 40 and a front-panel device port 42 (i.e., IN / OUT). The pads 40, 42 are each formed by two insulation displacement connectors 41 and each include arrays (eg, arrays, rows, columns or other groups) of contact elements 43 for connecting wires to the DSX module 34. The contact elements 43 are housed in housings 45 the connection pads 40, 42 worn. The housings 45 are mounted on a front cover 49 fixed to the front of the DSX module 34. The front cover piece 49 covers a front side of a circuit board 124 that provides electrical connections between the sockets 36 and 38 and the insulation displacement connectors 41 of the pads 40, 42. By a dielectric rear cover piece 126, a rear side of the printed circuit board 124 is covered.

When the DSX module 34 is assembled, retainers 127 are used to secure the female receptacle 35 and the front cover 49 to the coupling rear deck 126 together. In the assembled state, the printed circuit board 124 is positioned between the front structure formed by the female receptacle 35 and the front cover piece 49 and the rear structure formed by the rear cover piece 126. The holders 127 'may also be used to further secure the printed circuit board 124 to the rear decking 126.

It will be understood that the DSX module 34 may preferably be received in a chassis (a chassis 32 is shown schematically in FIGS FIG. 9A and 9B shown. To meet conventional international standards, the chassis can be approximately 48 cm long. This embodiment may, for example, accommodate 16 DSX modules. Alternatively, the chassis could be built to standard US specifications approximately 58.5 cm in length. This embodiment may, for example, accommodate 21 DSX modules. Of course, other chassis sizes and other numbers of DSX modules could be used. An exemplary chassis is in U.S. Patent No. 6,840,815 which is hereby incorporated by reference in its entirety.

d. contact elements

The contact element 43 is made of a conductive material, such as a metal material. For certain Embodiments, the contact elements 43 may be stamped from sheet metal. Like in the Fig. 2A shown, each contact element 43 includes a pair of cutting blade 51, which form the actual insulation displacement contact 54. Between the Schneidklemmessem 51, a contact slot 52 is formed. The cutting edge knives 51 are configured so that when an insulated cable core is inserted into the contact slot 52 between the cutting blade 51, the cutting edge blades 51 cut through the insulation of the cable core and into the conductive core of the wire to provide an electrical connection between the conductive core of the core Cable core and the contact element 43 produce. At the opposite end of the insulation displacement Kontakles 54, a pin contact 53 is arranged, which serves for connecting the contact element 43 with the circuit board 124. Below the insulation displacement contact 54, a guide member 56 is arranged, which has a rectangular shape, wherein the guide member 56 is wider than the insulation displacement contact 54. Further, the contact element 43 has a first extension 55 and a second extension 58 which electrically connect the insulation displacement contact 54 to the pin contact 53. By the extensions 55, 58, the insulation displacement contacts 54 are offset from the circuit board 124 to facilitate accessing the insulation displacement connectors 41 with a connection tool, not shown. In certain exemplary embodiments, the extensions 55, 58 have offset lengths OL (ie, the lengths corresponding to the distance that the IDC contacts 54 will be offset from the PCB) of at least 1 cm or lengths in the range of 1-3 centimeters , The second extension 58 serves to guide the pin contact 53 through the cover piece 49, 49 '. Arranged laterally between the first extension 55 and the second extension 58 are two arcuate elements 57 which, on the one hand, support the contact element 43 on the cover piece 49, 49 ', the arcuate elements 57 themselves being supported in the housing 45, so that the position of the contact element 43 is fixed. The two arcuate elements 57 are bent in opposite directions to each other.

e. IDC housing

Referring to the Figures 2 . 2b-d . 5 . 7 and 8 have the housing 45th generally rectangular shapes and include bottom sides 61 and wire terminal ends or tops 63. The top 63 defines slots 65 (see FIG Fig. 7 ) for receiving wires to be connected. The slots are aligned along parallel lines L so that the wires extend across the width of the housing 45 when connected. In the Fig. 7 is the top 63 of the IDC connector 41 shown. The housing 45 comprises clamping webs 64, between which slots 65 are formed for the wires to be connected. At an angle of 45 ° to the slots 65, the cutting knives 51 of the insulation displacement contacts 54 are arranged. The contact elements 43 are inserted from the bottom 61 in the housing 45, wherein in FIGS. 7 and 8 the state is shown with inserted contact elements 43. In this case, one recognizes the guide elements 56 and the arcuate element 57. The guide elements 56 lie in a groove 70, wherein in each case one outer edge of the guide element lies in a different groove 70. How very good in Fig. 2c can be seen, the groove 70 extends from the bottom of the housing 45 to the area where the insulation displacement contact 54 is located. In the walls that define the groove 70, slots 71 are introduced, in which the arcuate elements 57 lie. The length of the slots corresponds to the length of the arcuate elements 57, so that they abut against an edge 72 in the housing 45. Furthermore, locking lugs 69 (see Fig. 8 ), by means of which the insulation displacement connectors are latched to the recordings.

The insulation displacement connectors 41 on the patch panel 40 are the same as those on the device connector panel 42, but each housing 45 on the device connector panel 42 has two fewer contact elements 43. At the jumper panel 40, more contact elements 43 are provided to receive lead wires for connecting signal tracking light circuits used to track the jumper connections.

Each of the support structures 222 includes two side walls 224, upper and lower walls 225, 226, and a rear wall 227. The walls 224-227 define rectangular receptacles 230 sized to receive the underside 61 of the housings 45. The side walls 224 define openings 232 for receiving the detents 69 of the housings 45 to provide snap-fit connections that retain the housings 45 in the receptacles. The back walls 227 define openings 234 for receiving the pin contacts 53 of the contact elements 43 when the housings 45 are secured in the receptacles 230. The openings 234 defined by the rear walls 227 of the mating connection field 40 are preferably aligned with the plated-through holes 146 located on the second part 124b of the printed circuit board 124. The openings 234 defined by the rear walls 227 of the mating connection field 40 are preferably aligned with the plated-through holes 148 located on the second part 124 b of the printed circuit board 124.

II. Using the DSX system

It should be understood that the DSX system 30 functions in the same manner as a conventional DSX system. Through the (IN / OUT blocks) device connector panel 42, the jacks 36, 38 can be connected to digital devices. The jumper connection field 40 allows the sockets 36, 38 to be connected to each other by semi-permanent cable bridges. The sockets 36, 38 provide opening connections between the digital devices connected to the device connector panel 42 and the jumper interface 40. By inserting plugs into the MONITOR terminals of the jacks 36, 38, the jacks 36, 38 can be monitored for continuous signals without interrupting the signals. With the signal tracking lamp circuits, the monitored routed connections as in FIG U.S. Patent No. 6,116,961 described pursued become. Plugs may be plugged into the IN or OUT terminals of the jacks 36, 38 for testing or diagnostic purposes or to redirect signals to other digital devices.

III. Alternative embodiment

Characters. 10-15B show another DSX module 34 'having features that are examples of aspects of the invention in accordance with the principles of the present disclosure. Many of the components of the DSX module 34 'are identical to components of the DSX module 34. Identical reference numbers have been assigned to these identical components.

The DSX module 34 'has the same basic components as the DSX module 34, only the device connector panel 42 has been routed to the back of the module. To account for this change, the DSX module 34 'includes a shortened printed circuit board 124' having a greater density of plated-through holes for connecting the insulation displacement. Connector 41 of the connection pads 40, 42 of the circuit board 124 '. Also, the DSX module 34 'includes a back cover 126' that has been shortened and modified to include receptacles 230 that receive the insulation displacement connectors 41 that define the device connector panel 42 located at the back of the module 34 '. In addition, the DSX module 34 'includes a front cover piece 49' which has been shortened and modified to eliminate the lower set of receptacles 230.

Although the disclosed insulation displacement mounting structure has been illustrated as being used in combination with a DSX module, it will be understood that the structure can be applied to any type of DSX system (modular or non-modular). In addition, the insulation displacement mounting structure is also applicable to any type of board-mounted insulation displacement application.

The connection pads 40, 42 have each been shown as insulation displacement connectors 41. Regardless of whether the connector panels 40, 42 are both from the front or the device connector panel 42 of the Reverse accessible, mixed structures can also be applied. Thus, for example, a terminal box as insulation displacement connector 41 and the other terminal box as a coaxial connector, such as Balun, M4, 1.0 / 2.3, 1.6 / 5-6, SMB or Type 43 coaxial connector or as RJ plug connectors, in particular RJ 45 plug connectors (shielded or unshielded), may be formed. In this case, the patch panel 40 is preferably designed as insulation displacement connector 41 and the device connection field 42 is formed as a coaxial or RJ connector. In addition, other connector types such as D-Sub are possible.
