Description

Data socket

Technical Field

The invention relates to a connection socket having a switching 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.

Background

Such a connection socket is known for example as an RJ-45 data socket and is installed in particular in a concealed manner. For this purpose, the connection socket is connected to a cable which leads into the concealed cup and is then inserted into the concealed cup. However, due to the small installation space, connecting the connection socket to the cable is complicated and can sometimes only be carried out together.

Disclosure of Invention

It is therefore an object of the present invention to provide a connector socket of the type mentioned in the introduction, which simplifies handling during connection.

To achieve the object, a terminal socket is proposed with the measures and features of the independent claims. In order to achieve the object, it is therefore proposed, in particular, in a connecting socket of the type mentioned at the outset: the connection interface has at least one blade-shaped terminal contact and at least one insertion means associated with the blade-shaped terminal contact, by means of which at least one core wire of a cable to be connected to a connection socket of the connection socket can be electrically connected to the blade-shaped terminal contact by means of a relative movement between the insertion means and the blade-shaped terminal contact.

The core of the cable can be connectable to the blade-shaped cable clamp contact by a relative movement of the insertion means with respect to the blade-shaped cable clamp contact.

In this way, a connection socket of the type mentioned at the outset is provided, which enables a tool-free electrical connection of a cable to the at least one connection socket of the connection socket. It is therefore possible to dispense with the use of so-called setting tools for connecting the connection socket to the cable.

The at least one insertion means can be provided for inserting and electrically connecting the at least one core wire to the blade clamp contact. The at least one jack may be an RJ-45 jack, for example.

It is to be noted here that the at least one connection socket of the connection socket can be arranged or formed on the end user side of the switching insert. The cable can be connected to the at least one connection socket via a connection interface of the switching insert, which connection interface can be arranged or formed on the so-called cable side of the switching insert or of the connection socket.

In one embodiment of the connection socket, it is provided that the at least two wires and/or the at least one two-wire of the cable can be electrically connected to the blade clamp contact by a relative movement between a feed-in element of the connection socket and the blade clamp contact associated with the feed-in element.

In this case, the at least one insertion means of the connection interface can be designed for inserting at least two wires and/or at least one double wire and/or can be adapted to at least two blade-shaped terminal contacts. In this way, two or more core wires and/or at least one two-core wire can be electrically connected to a corresponding number of blade-shaped wire clamping contacts by means of the insertion device.

In a particularly advantageous embodiment of the connection socket, which allows particularly comfortable electrical connection, the at least one insertion means is designed as a sliding block.

The lead-in means can be moved between a receiving position, in which it can receive at least one core wire of the cable, and a contact position. The at least one core wire can be electrically connected to the blade clamp contact by moving the insertion means into the contact position. This is achieved, for example, by introducing the core wire between the edges of the at least one blade clamp contact by means of a lead-in device. In this case, the blade edge can cut through the insulation sheath of the core wire and make contact with the conductor of the core wire, and thus electrically connect the core wire to the blade clamp contact. The at least one insertion means can be mounted on the switching insert so as to be movable between a receiving position and a contact position, for example via a sliding block.

The insertion means can be lockable in the receiving position. This facilitates the positioning of the core wire of the cable on or in the insertion means in such a way that the core wire can be electrically connected to the blade clamp contact by means of the insertion means. The insertion means can be lockable in the receiving position by means of a locking point. For this purpose, at least one corresponding latching point can be formed between the insertion device and the switching insert of the connection socket.

In order to prevent the insertion means from being unintentionally released in the contact position, it can be advantageous if the insertion means can be locked in the contact position. This can also be achieved, for example, by at least one latching point which, in the contact position of the insertion part, is formed between the insertion part and the switching insert of the connection socket.

In one embodiment of the connector socket, it is provided that the at least one insertion means has at least one plug receptacle for a core end of the core. When the insertion device is arranged in the receiving position already mentioned above, the core of the cable can be inserted with its core end into the plug-in receiving portion of the insertion device. The insertion part can then be moved into a contact position together with the core wire end located in the plug receptacle of the insertion part, in order to establish an electrical contact between the at least one blade-shaped wire clamp contact of the connection socket and the core wire of the cable.

In a preferred embodiment of the connection socket, the at least one insertion device has two insertion receptacles for one core wire each. Thus, two wires of the cable can be received by one lead-in device and can be electrically connected to the blade clamp contact by a relative movement between the lead-in device and the blade clamp contact. Therefore, the plurality of core wires can be reliably and quickly connected to the terminal socket.

The at least one plug receptacle of the at least one insertion part can have a longitudinal axis which is oriented transversely or perpendicularly to a relative movement which is carried out between the at least one insertion part and the at least one blade-shaped cable clamp contact in order to electrically connect the core wire of the cable to the blade-shaped cable clamp contact.

The connection of the core wire to the blade-shaped wire clamping contact is particularly reliable if the at least one blade-shaped wire clamping contact is oriented obliquely to the longitudinal axis of the core wire connected to the blade-shaped wire clamping contact and/or obliquely to the insertion direction of the core wire into the insertion device. The at least one blade-shaped wire clamping contact can be oriented at an angle of 45 ° with respect to the longitudinal axis of the core wire connected to the blade-shaped wire clamping contact and/or with respect to the insertion direction of the core wire into the insertion device.

In a preferred embodiment of the connection socket, it is provided that each insertion means is assigned to a respective pair of blade-shaped terminal contacts. Furthermore, the at least one insertion means can have at least two plug receptacles for the ends of the core wires. When the insertion openings of the two plug sockets of such a lead-in device are arranged in different planes of the lead-in device, the insertion openings of the plug sockets of the lead-in device for the core wire ends of the core wires to be connected have a height offset from one another. By means of this height offset, the two core wires can be successively introduced into the blade clamp contact by means of an introduction device. By virtue of the offset arrangement of the plug receptacles, the cutting forces occurring in this case can be overcome individually for each core wire, which requires a low force for connecting the core wires. This can considerably simplify the production of an electrical connection between the core wires of the cable and the blade clamp contacts and furthermore protect the connection socket, in particular the switching insert and the insertion device.

In one embodiment of the connection socket, it is provided that the switching insert has at least one sheathing/shielding clamp (Schirm-Klemme). The sheath clamp can be used to securely fasten a sheath of a cable, which may be made of a braid and/or a film, for example, to a connector housing and to electrically shield the connector housing in a desired manner.

In one embodiment of the sheathing clamp, it is provided that the sheathing clamp has a clamp slot which defines an insertion direction through its insertion opening for the cable sheath, which insertion direction is opposite to the insertion direction of the core wire end into the at least one insertion means. Furthermore, the wire grip gap of the sheathing wire grip may have at least one undercut, for example, may be serrated. In this way, the cable sheath of the cable can be prevented from being pulled out and can thus be reliably fixed to the sheath clamp of the connection socket.

In one embodiment of the connection socket, the connection interface can have at least two blade-shaped terminal contacts offset from one another and/or at least two pairs of blade-shaped terminal contacts offset from one another and/or at least two insertion devices offset from one another. This may simplify the connection of the core wires of the cable to the wiring interface. The offset can be present in the insertion direction of the core wire into the insertion device and/or in the direction of the carrier plate of the connection socket, which carrier plate can be connected to the switching insert.

The switching insert can have a circuit board/board which has at least one blade clamp contact and a corresponding insertion means on the sides facing away from each other. In this case, the blade clamp contacts and/or insertion means on one side of the circuit board can be arranged offset with respect to the blade clamp contacts and/or insertion means on the other side of the circuit board. In particular, the insertion means and/or the blade-shaped terminal contacts on different sides of the circuit board can have an offset in the insertion direction of the core wires into the insertion means and/or can have an offset in the direction of the carrier plate of the connection socket, which carrier plate can be connected or is connected to the switching insert.

In particular, when the switching insert and/or its circuit board have an inclined position relative to the aforementioned carrier plate, a staggered arrangement of the blade-shaped terminal contacts and/or insertion means on different sides of the circuit board can be achieved, which are arranged in a common terminal plane oriented obliquely relative to the circuit board. This may simplify the connection of the patch socket to the cable.

The switching insert may also have a housing. In this housing, for example, the previously mentioned circuit board can be arranged. The housing may be arranged to shield electromagnetic radiation. It is particularly advantageous if the housing is made of metallized plastic. In this way, the housing can achieve the desired shielding properties and can furthermore be produced at relatively low cost.

It is pointed out here that the use of housings made of metallized plastic throughout the field of information and communication technology can be of interest in all areas in which a shielding effect with respect to electromagnetic radiation is advantageous in this connection. Thus, for example, even in connection strips, in particular LSA connection strips, as they are used, for example, in telecommunications technology at distribution points.

As already mentioned above, the connection socket can have a carrier plate. The carrier plate can be detachably connected to the switching insert. For this purpose, a detachable connection, for example a latching connection, preferably a non-destructively detachable latching connection, can be formed between the carrier plate of the connection socket and the switching insert. In this way, the at least one connection socket of the connection socket can be connected to the cable with the switching insert detached from the carrier plate and the switching insert can then be connected to the carrier plate of the connection socket. The carrier plate can then be fixed, for example, with the switching insert on the built-in cup for the assembly of the connection socket. If the latch connection is a non-destructively detachable latch connection, the switching insert can be detached from the carrier plate if necessary without damaging the connecting elements of the latch connection.

In order to adapt the carrier plate of the connection socket to different installation dimensions, the carrier plate can have at least one predetermined breaking point for tool-free adaptation of the size and/or geometry of the carrier plate. At the at least one predetermined breaking point, the carrier plate can be broken off and thereby reduced. Preferably, the carrier plate has a plurality of predetermined breaking points, in particular arranged uniformly distributed around a center point of the carrier plate. These predetermined breaking points can be predetermined breaking lines or predetermined breaking edges, for example. Such a setting of the breaking points facilitates a uniform and/or symmetrical, in particular mirror-symmetrical, adaptation of the geometry of the carrier plate.

The carrier plate may also have a ground connection point. The ground connection point may be formed by a flat plug. Thus, the connection socket can be connected with a ground cable.

In one embodiment of the connection socket, a circuit board of the switching insert, for example the previously mentioned circuit board and/or the insertion direction of the core wire into the at least one insertion part and/or the longitudinal axis of the plug receptacle of the at least one insertion part, for example the previously mentioned plug receptacle, is oriented perpendicularly or obliquely with respect to the previously mentioned carrier plate, in particular at an angle of between 30 ° and 60 °, preferably at an angle of 45 °.

In this way, it is possible for the insertion openings of the connection sockets to have an inclined position relative to the aforementioned carrier plate of the connection socket. The insertion opening of the at least one connection socket can be oriented obliquely downward in the use position of the connection socket. In this way, a cable on the end user side, for example an ethernet cable, can be inserted with its plug obliquely downwards into the at least one connection socket of the connection socket. With this arrangement, cables that have been inserted into the wiring sockets of the wiring receptacle are well protected against accidental shearing.

In one embodiment of the connection socket, the switching insert can be oriented perpendicularly or obliquely, in particular at an angle of between 30 ° and 60 °, preferably at an angle of 45 °, to the aforementioned carrier plate.

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

Detailed Description

All figures show a connection socket designated as a whole by 1. The connection socket 1 has a switching insert 2 which comprises two connection sockets 3 on its subscriber side and a connection interface 4 on its cable side. The two connection sockets 3 of the connection socket 1 can be connected to a cable via a connection interface 4.

Fig. 2 shows diagrammatically that the connection interface 4 has a total of 16 blade-clamp contacts 5 and a total of 8 insertion devices 6, which are each associated with two of the 16 blade-clamp contacts 5 of the connection socket 1.

By means of the insertion means 6, two wires 7 of a cable to be connected to the connection socket 1 can be connected electrically to the blade clamp contact 5 by relative movement between the insertion means 6 and the blade clamp contact 5.

The insertion means 6 is designed as a slide and can be moved between a receiving position and a contact position.

In the connection socket 1 shown in fig. 2, the first and third lead-in devices 6 of the upper row of the two rows of lead-in devices 6 of the connection socket 1 are shown in their receiving positions, respectively.

Of the total four lead-in devices 6 in the lower row, the first lead-in device 6 from the right is shown in its receiving position. The remaining lead-in elements 6 of the connection socket 1 are in their contact position in which they have electrically connected the core wires 7 of the cable to the blade clamp contacts 5.

The insertion means 6 can be locked not only in its receiving position but also in its contact position. For this purpose, a corresponding latching point 23 is formed between the insertion means 6 and the switching insert 2.

Each insertion device 6 has two plug receptacles 8 for one core end of one core 7 of the cable. Each lead-in device 6 is associated with two blade-shaped clamp contacts 5. Thus, the introduction means 6 can be used to introduce and connect two core wires 7 or twisted two core wires. The longitudinal axis of the plug receptacle 8 is oriented transverse or perpendicular to the relative movement of the insertion means 6, in which the insertion means 6 is moved relative to its blade-shaped terminal contact 5 to electrically connect the core wires 7.

The blade-shaped terminal contacts 5 of the connection socket 1 are oriented obliquely, i.e. at an angle of 45 ° with respect to the longitudinal axis of the plug receptacle 8 for the core wire ends of the core wires 7, and thus also at an angle of 45 ° with respect to the longitudinal axis of the core wires 7 to be connected to the respective blade-shaped terminal contacts 5, and thus also correspondingly obliquely with respect to the insertion direction of the core wires 7 into the insertion device 6.

As already mentioned above, a respective one of the eight leadthrough devices 6 in total is assigned to a respective pair of blade-shaped terminal contacts 5.

Each insertion device 6 has a total of two plug sockets 8 for the core wires 7, the insertion openings 9 of which are arranged in different planes of the respective insertion device 6. In this way, the insertion openings 9 of the plug sockets 8 are aligned with a height offset from one another. This helps to reduce the effort required for pressing the core wires 7 located in the plug sockets 8 into the blade-shaped terminal contacts 5 of the connection socket 1.

The previously described height offset of the insertion opening 9 of the insertion device 6 can be seen particularly well from the view of the connection socket 1 according to fig. 3.

Fig. 2, for example, shows diagrammatically that the connection socket 1 has one sheathing clamp 10, i.e., a total of two sheathing clamps, on both sides of its switching insert 2. Each sheathing clamp 10 has a clamp slot 11, which defines an insertion direction through its insertion opening 12 for the cable sheathing, which is opposite to the insertion direction of the core ends of the cores 7 into the insertion device 6. Each sheathing clamp 10 also has two lateral recesses 13 in its clamp slot 11, which help to securely lock the cable sheathing introduced into the clamp slot 11 in the clamp slot 11.

The switching insert 2 comprises a circuit board/board 14 which has four pairs of blade-shaped terminal contacts 5 with a total of four associated insertion devices 6 on the

sides

15 and 16 facing away from each other. The circuit board 14 is arranged in a housing 27 of the switching insert 2. The housing 27 is made of plastic, which has a shielding effect by means of metallization. This makes it possible to avoid interference signals being coupled in and facilitates the function of the connector socket 1.

The blade clamp contact 5 with its insertion device 6 on the side 15 of the printed circuit board 14 is arranged offset with respect to the blade clamp contact 5 with its insertion device 6 on the other side 16 of the printed circuit board 14. This offset can be seen particularly well in the side view of the connection socket 1 according to fig. 5.

The connection interface 4 of the connection socket 1 shown in the figures therefore has a plurality of pairs of blade-shaped terminal contacts 5 arranged offset from one another and a plurality of insertion devices 6 arranged offset from one another.

The offset can be measured in the insertion direction of the core wire 7 into the insertion device 6 and in the direction of the carrier plate 17 of the connection socket 1 connected to the switching insert 2. The switching insert 2 of the connection socket 1 is detachably connected to the carrier plate 17. For this purpose, a latching connection 18 is provided between the switching insert 2 and the carrier plate 17. The latch connection 18 may be a latch connection that can be removed without damage. In this way, the switching insert 2 can be separated from the carrier plate 17 when required, without damaging the connecting elements of the detent connection 18.

Fig. 1 furthermore shows that the carrier plate 17 of the connector socket 1 has a plurality of predetermined breaking points 19 for tool-free adaptation of the size and geometry of the carrier plate 17. The flaps 20 of the carrier plate 17 can be broken at the set breaking points 19.

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

The circuit board 14 of the switching insert 2, the insertion direction of the core wire 7 into the insertion device 6 and the longitudinal axis of the plug receptacle 8 of the insertion device 6 are oriented obliquely to the carrier plate 17, in this case at an angle of between 30 ° and 60 °, preferably at an angle of 45 °.

The patch panel jack 1 shown in the various figures is an RJ-45 data jack. One of the wiring jacks 3 is occupied by an RJ-45 plug 22. In the position of use, the connection socket 1 is inserted into the concealed cup 24 and is provided with a stop 25.

The switching insert 2 is supported on the carrier plate 17 at three bearing points 26. The bearing points 26 ensure that the switching insert 2 is held stably on the carrier plate 17.

The invention relates to an improvement in the technical field of connection sockets, in particular data sockets. To this end, a connection socket 1 is also proposed, which has a connection interface 4 with at least one blade-shaped terminal contact 5 and at least one insertion means 6 assigned to the blade-shaped terminal contact 5, with which insertion means a conductor 7 of a cable to be connected to the connection socket 1 can be electrically connected to the blade-shaped terminal contact 5 by means of a relative movement between the insertion means 6 and the blade-shaped terminal contact 5.
