Description

The invention relates to a connection box with a switch insert, which comprises at least one connection socket and a connection interface, via which the at least one connection socket can be connected to a cable.

Such connection sockets are already known, for example as RJ-45 data sockets, and are installed flush-mounted in particular. To do this, the junction boxes are connected to a cable that ends in a flush-mounted cup and then inserted into the flush-mounted cup. Due to the small installation space, however, the connection of the junction box to the cable is comparatively complex and can sometimes only be carried out by two people.

The object of the invention is therefore to provide a junction box of the type mentioned at the outset, the handling of which is simplified when connecting.

To solve the problem, a junction box with the means and features of the independent claim is proposed. In order to achieve the object, it is therefore proposed in particular for a connection box of the type mentioned at the outset that the connection interface has at least one insulation displacement contact and at least one feed means assigned to the insulation displacement contact, with which at least one wire of the cable to which the Connection socket of the junction box is to be connected, can be electrically connected to the insulation displacement contact by a relative movement between the feed means and the insulation displacement contact.

The core of the cable can be connected to the insulation displacement contact by a movement of the feed means relative to the insulation displacement contact.

In this way, a connection box of the type mentioned is provided, which enables a tool-free electrical connection of a cable to the at least one connection socket of the connection box. The use of so-called application tools for connecting the junction box to the cable can thus be dispensed with.

The at least one supply means can be set up for the supply and electrical connection of at least one wire to an insulation displacement contact. The at least one connection socket can be an RJ-45 connection socket, for example.

At this point it should be mentioned that the at least one connection socket of the connection box can be arranged or formed on an end user side of the switch insert. The connection interface of the switch insert, via which the cable can be connected to the at least one connection socket, can be arranged or formed on a so-called cable side of the switch insert or the connection socket.

In one embodiment of the connection box, it is provided that at least two cores and/or at least one double core of the cable can be electrically connected to the insulation displacement contacts by a relative movement between a feed means of the connection box and insulation displacement contacts assigned to this feed means.

At least one feed means of the connection interface can be designed to feed at least two wires and/or at least one pair of wires and/or be assigned to at least two insulation displacement contacts. In this way, two or more cores and/or at least one pair of cores can be electrically connected to a feed means with a corresponding number of insulation displacement contacts.

In a particularly advantageous embodiment of the junction box, which allows a particularly convenient electrical connection, the at least one feed means is designed as a slide.

The feeding means can be movable between a receiving position, in which the feeding means can receive at least one wire of a cable, and a contact position. By moving the feed means into the contact position, the at least one wire can be electrically connected to the insulation displacement contact. This can be done, for example, by inserting the wire between the cutting legs of the at least one insulation displacement contact using the feed means. The cutting limbs can cut through an insulating sleeve of the wire and can be brought into contact with a conductor of the wire and the wire can thus be electrically connected to the insulation displacement contact. The at least one feed means can be movably mounted on the switch insert between the receiving position and the contact position, for example via a sliding seat.

The feeding means can be locked in the receiving position. This makes it easier to position a wire of a cable on or in the feed means that the wire can be electrically connected to the insulation displacement contact using the feed means. The supply can in the on position can be locked by a locking point. For this purpose, at least one corresponding latching point can be formed between the feed means and the switch insert of the connection socket.

In order to prevent the feed means from being unintentionally released in the contact position, it can be advantageous if the feed means can be locked in the contact position. This can also be done, for example, by at least one locking point that is formed between the feed means and the switch insert of the connection socket in the contact position of the feed means.

In one embodiment of the junction box, it is provided that the at least one feed means has at least one plug-in receptacle for a wire end of a wire. When the feed means is arranged in the previously mentioned receiving position, the wire end of a core of the cable can be pushed into the plug-in receptacle of the feed means. The feeder can then be moved into the contact position together with the wire end positioned in the plug-in receptacle of the feeder, in order to establish electrical contact between the at least one insulation displacement contact of the connection socket and the wire of the cable.

In a preferred embodiment of the junction box, the at least one feed means has two plug-in receptacles, each for one wire. Thus, two cores of the cable can be picked up by a feeding device and electrically connected to the insulation displacement contacts by a relative movement between the feeding device and the insulation displacement contacts. In this way, a large number of wires can be connected to the junction box quickly and reliably.

The at least one plug-in receptacle of the at least one feed means can have a longitudinal axis which is aligned transversely or at right angles to the relative movement between the at least one feed means and the at least one insulation displacement contact for the electrical connection of the wire of the cable to the insulation displacement contact -Contact is carried out.

If the at least one insulation displacement contact is aligned obliquely to a longitudinal axis of a wire connected to the insulation displacement contact and/or obliquely to a direction in which a wire is inserted into the feed means, the wire can be connected particularly reliably to the insulation displacement contact get connected. The at least one insulation displacement contact can be aligned, for example, at an angle of 45° to a longitudinal axis of a wire connected to the insulation displacement contact and/or direction of insertion of a wire into the feed means.

In a preferred embodiment of the junction box, it is provided that one feed means is assigned to a pair of insulation displacement contacts. Furthermore, the at least one feed means can have at least two plug-in receptacles for wire ends. If the insertion openings of the two plug-in receptacles of such a supply means are arranged in different levels of the supply means, the insertion openings of the plug-in receptacles of the supply means for the wire ends of the wire to be connected are offset in height relative to one another. This height offset makes it possible to feed the two wires to the insulation displacement contacts using the feed means one after the other. Due to the staggered arrangement of the sockets, the cutting forces that occur must be overcome for each wire individually, which means that less force is required to connect the wires. This can considerably simplify the production of the electrical connection between the wires of the cable and the insulation displacement contacts and also protect the junction box, in particular the switch insert and the feed means.

In one embodiment of the junction box, it is provided that the switch insert has at least one shield clamp. The shielding clamp can be used to reliably attach a shielding of the cable, which can consist of braiding and/or a film, for example, to the junction box and to provide the electrical shielding of the junction box in the desired manner.

In one embodiment of the shield clamp, it is provided that it has a clamping gap which, through its insertion opening for a cable shield, defines an insertion direction which is opposite to a direction in which wire ends are inserted into the at least one feed means. Furthermore, the clamping gap of the shield clamp can have at least one undercut, for example serrated. In this way, the cable shielding of the cable can be prevented from being pulled out and thus reliably fixed to the shielding clamp of the junction box.

In one embodiment of the connection box, the connection interface can have at least two offset insulation displacement contacts and/or at least two pairs of offset insulation displacement contacts and/or at least two feed means offset with respect to one another. This can simplify the connection of cores of a cable to the connection interface. The offset can be in the direction of insertion of wires into the feed means and/or in the direction of a carrier plate of the junction box to which the switch insert can be connected.

The switch insert can have a circuit board, which has at least one insulation displacement contact with associated feed means on opposite sides. In this case, insulation displacement contacts and/or feed means can be arranged offset on one side of the circuit board in relation to insulation displacement contacts and/or feed means on another side of the circuit board. In particular, the feed means and/or the insulation displacement contacts on the different sides of the circuit board can have an offset in the direction in which wires are inserted into the feed means and/or an offset in the direction of a carrier plate of the junction box with which the switch insert can be connected or is connected .

In particular when the switch insert/or its circuit board is inclined relative to the aforementioned support plate, the staggered arrangement of the insulation displacement contacts and/or feed means on the different sides of the circuit board enables them to be aligned in a common manner obliquely to the circuit board Connection level are arranged. This can simplify the connection of the junction box to a cable.

The switch insert can also have a housing. For example, the circuit board mentioned above can be arranged inside the housing. The housing can be set up to shield against electromagnetic radiation. It is particularly advantageous if the housing consists of metalized plastic. In this way, the housing can obtain the desired shielding properties and can also be manufactured comparatively inexpensively.

At this point it should be mentioned that the use of housings made of metalized plastic can make sense in the entire field of information and communication technology wherever the associated shielding effect against electromagnetic radiation is advantageous. This is also the case, for example, with connection strips, in particular LSA connection strips, such as those used at distribution points in telecommunications technology.

As already indicated above, the junction box can have a carrier plate. The support plate can be detachably connected to the switch insert. For this purpose, a releasable connection, for example a snap-in connection, preferably a non-destructively releasable snap-in connection, can be formed between the carrier plate and the switch insert of the connection box. In this way it is possible to connect the at least one connection socket of the connection box to the cable when the switch insert is detached from the carrier plate and then to connect the switch insert to the carrier plate of the connection box. The support plate can then be attached together with the switch insert, for example, to a flush-mounted cup for mounting the junction box. If the snap-in connection is a snap-in connection that can be released non-destructively, the switch insert can be separated from the carrier plate if necessary, without damaging the connecting elements of the snap-in connection.

In order to adapt the support plate of the junction box to different installation dimensions, the support plate can have at least one predetermined breaking point for tool-free adjustment of the size and/or geometry of the support plate. The carrier plate can be broken at the at least one predetermined breaking point and thereby reduced in size. The carrier plate preferably has a plurality of predetermined breaking points, in particular arranged uniformly distributed around a center point of the carrier plate. The predetermined breaking points can be predetermined breaking lines or predetermined breaking edges, for example. Such predetermined breaking points favor a uniform and/or symmetrical, in particular mirror-symmetrical, adaptation of the geometry of the carrier plate.

The support plate can also have a ground connection point. This can be formed by a tab. This allows the junction box to be connected to a grounding cable.

In one embodiment of the junction box, a printed circuit board, for example the one mentioned above, of the switching insert and/or a direction of insertion of a wire into the at least one feed means and/or a longitudinal axis of a plug-in receptacle, for example the one already mentioned above, of the at least one feed means can be perpendicular or inclined , in particular at an angle of between 30° and 60°, preferably at an angle of 45°, to the aforementioned carrier plate.

In this way it is possible for an insertion opening of the connection socket to have an inclined position in relation to the previously mentioned carrier plate of the connection socket. In this case, the insertion opening of the at least one connection socket can be aligned obliquely downwards in the usage position of the connection socket. In this way, a cable from the end user, for example an Ethernet cable, can be plugged into the at least one connection socket of the connection socket with its plug at an angle from below. With this arrangement, the cable that is plugged into the connection socket of the junction box is well protected against unintentional shearing off.

In one embodiment of the junction box, the switch insert can be aligned at right angles or at an angle, in particular at an angle between 30° and 60°, preferably at an angle of 45°, to the aforementioned carrier plate.

In one embodiment of the connection socket, this is designed as an RJ-45 data socket. Furthermore, the connection box can have at least two connection sockets, preferably arranged next to one another.

Further exemplary embodiments are obtained by combining the features of individual or multiple claims with one another and/or by combining individual or multiple features of the exemplary embodiment.
Show it:

• 2 an isometric rear view of the in 1 shown junction box, wherein the multiple insulation displacement contacts and the insulation displacement contacts associated feed means of the connection interface can be seen with which wires of the cable by a relative movement between the feed means and the insulation displacement contacts with the insulation displacement contacts are electrically connectable,

• 7 a front view of the in 6 shown junction box in the flush-mounted cup.

All of the figures each show a junction box labeled 1 as a whole. The connection box 1 has a switch insert 2 which has two connection sockets 3 on its user side and a connection interface 4 on its cable side. The two connection sockets 3 of the connection socket 1 can be connected with a cable via the connection interface 4 .

2 makes it clear that the connection interface 4 has a total of 16 insulation displacement contacts 5 and a total of eight feed means 6 which are each assigned to two of the 16 insulation displacement contacts 5 of the connection box 1 .

With the aid of the feed means 6, two cores 7 of the cable to which the junction box 1 is to be connected can be electrically connected to the insulation displacement contacts 5 by a relative movement between the feed means 6 and the insulation displacement contacts 5.

The feed means 6 are designed as slides and can be moved between a receiving position and a contact position.

At the in 2 Connection box 1 shown, the first and third feed means 6 of an upper row of two feed means 6 of the connection box 1 are each shown in their receiving position.

In the bottom row of a total of four feed means 6, the first feed means 6 seen from the right is shown in its receiving position. The other feed means 6 of the junction box 1 are in their contact position, in which they have already electrically connected the wires 7 of the cable to the insulation displacement contacts 5 .

The feeding means 6 can be locked both in their receiving position and in their contact position. For this purpose, corresponding latching points 23 are formed between the feed means 6 and the switch insert 2 .

Each of the supply means 6 has two sockets 8 for one wire end of a wire 7 of the cable. Each feed means 6 is assigned to two insulation displacement contacts 5 respectively. Thus, the supply means 6 can be used for supplying and connecting two wires 7 or twisted pair wires. Longitudinal axes of the plug-in receptacles 8 are aligned transversely or at right angles to the relative movement of the feed means 6, in which the feed means 6 is moved relative to its insulation displacement contacts 5 for the electrical connection of the wires 7.

The insulation displacement contacts 5 of the junction box 1 are inclined, namely at an angle of 45° to a longitudinal axis of the plug-in receptacles 8 for the wire ends of the wires 7 and thus also at an angle of 45° to a longitudinal axis a wire 7 to be connected to the respective insulation displacement contact 5 and thus also correspondingly inclined to a direction of insertion of a wire 7 into the feed means 6 .

As already mentioned above, one of the total of eight feed means 6 is assigned to a pair of insulation displacement contacts 5 in each case.

Each of the supply means 6 has a total of two plug-in receptacles 8 for wires 7, the insertion openings 9 of which are arranged in different levels of the respective supply means 6. In this way, the insertion openings 9 of the plug-in receptacles 8 are aligned with one another with a height offset. This helps to reduce the effort required to press the wires 7 located in the sockets 8 into the insulation displacement contacts 5 of the junction box 1 .

The above-described height offset of the insertion openings 9 of the feed means 6 is particularly clear based on the illustration of the connection box 1 according to FIG 3 to recognize.

For example 2 shows that the junction box 1 has one shield clamp 10 on each side of its switch insert 2 , ie a total of two shield clamps 10 . Each of the shield clamps 10 has a clamping gap 11 which, through its insertion opening 12 for a cable shield, defines an insertion direction which is opposite to a direction in which the wire ends of the wires 7 are inserted into the feed means 6 . Each of the shielding clamps 10 also has two undercuts 13 in its clamping gap 11, which help to securely lock a cable shielding inserted into the clamping gap 11 in the clamping gap 11.

The switching insert 2 comprises a circuit board 14 which has four pairs of insulation displacement contacts 5 with their four associated feed means 6 on opposite sides 15 and 16 . The circuit board 14 is arranged in a housing 27 of the switch insert 2 . The housing 27 consists of plastic, which has a shielding effect due to metallization. This can prevent interference signals from being coupled in and promote the function of the junction box 1.

The insulation displacement contacts 5 with their feed means 6 on the side 15 of the circuit board 14 are arranged offset to the insulation displacement contacts 5 and their feed means 6 on the other side 16 of the circuit board 14 . This offset is particularly good in the side view of the junction box 1 according to 5 to recognize.

The connection interface 4 of the connection box 1 shown in the figures thus has a plurality of pairs of insulation displacement contacts 5 arranged offset relative to one another and a plurality of feed means 6 arranged offset relative to one another.

The offset can be measured in the direction of insertion of the wires 7 into the feed means 6 and in the direction of a carrier plate 17 of the junction box 1 to which the switch insert 2 is connected. The switch insert 2 of the connection box 1 is detachably connected to the carrier plate 17 . For this purpose, a latching connection 18 is provided between the switch insert 2 and the support plate 17 . The latching connection 18 can be a non-destructively releasable latching connection. In this way, the switching insert 2 can be separated from the carrier plate 17 if necessary, without damaging the connecting elements of the snap-in connection 18 .

Among other things 1 shows that the support plate 17 of the junction box 1 has several predetermined breaking points 19 for tool-free adjustment of the size and geometry of the support plate 17. Wings 20 of support plate 17 can be broken off at predetermined breaking points 19 .

The support plate 17 also has a ground connection point 21 for a flat plug.

The circuit board 14 of the switch insert 2, an insertion direction of a wire 7 in the feed means 6 and longitudinal axes of the plug-in receptacles 8 of the feed means 6 are oriented obliquely, here at an angle between 30° and 60°, preferably at an angle of 45°, to the carrier plate 17 .

The connection socket 1 shown in the figures is an RJ-45 data socket. One of the connection sockets 3 has an RJ-45 connector 22 occupied. In the position of use, the connection box 1 is inserted into a flush-mounted cup 24 and is provided with a screen 25 .

The switching insert 2 is supported on the carrier plate 17 at three support points 26 . The contact points 26 ensure that the switching insert 2 is held securely on the carrier plate 17 .

The invention deals with improvements in the technical field of connection sockets, in particular data sockets. For this purpose, a connection box 1 is proposed, among other things, which has a connection interface 4, which has at least one insulation displacement contact 5 and at least one feed means 6 assigned to the insulation displacement contact 5, with which a wire 7 of a cable to which the connection box 1 is to be connected by a relative movement between the feeding means 6 and the insulation displacement connector clock 5 can be electrically connected to the insulation displacement contact 5.
