Description

Contact insert for plug-in connector parts which can be connected to mating plug-in connector parts

Technical Field

The invention relates to a contact insert for a plug-in connector part that can be connected to a mating plug-in connector part according to the preamble of claim 1.

The contact insert has a retention frame and at least one contact module. The at least one contact module has a module housing and at least one electrical contact element for making electrical contact with a mating plug connector part, wherein the at least one contact module can be attached to a holding frame to form a contact insert.

Such contact inserts may be manufactured in a modular manner, wherein the holding frame forms one or more plug-in locations for one or more contact modules, so that the holding frame may be assembled in a modular manner for one or more contact modules. The contact plug configured in this way can then be inserted into the housing of the plug connector part in order to complete the plug connector part in this way.

The different contact modules can provide different arrangements of the contact elements, whereby a modularly configurable plug connector part with the plug surfaces provided by the contact modules can be achieved by a modular assembly of the holding frame.

Background

Different designs of modularly assemblable contact inserts are known, for example, from DE 20 2012 103 360U1, DE 20 2006 012 687 U1 and EP 1 026 788 A1.

A plug connector part can be created by means of the contact plug, which is used, for example, for connecting an electrical cable to an electrical component, such as a switch cabinet, or to another cable. The power signals can be transmitted via the contact insert and the contact module arranged thereon, but the data signals can also be transmitted.

Although contact inserts with a modularly mountable holding frame are used in particular for so-called heavy-duty plug connectors (also referred to as industrial plug connectors) for industrial applications and are particularly protected, for example, by a surrounding housing, other plug connectors are known, for example, for data transmission. For example, so-called M12 plug connectors are used to establish data connections, such as ethernet connections, by creating quadrupole connections. Because of the transmission frequencies used (e.g., in the gigahertz range), data transmission requires electromagnetic shielding, such plug connectors are tailored in a special manner, especially in terms of shielding, and are typically delivered to customers already in mass-produced and connected form with electrical data conductors by the suppliers.

Such a wire connector used on (data) wires can be designed in particular as a so-called push-pull connector, which enables a plug-in connection with another wire connector and is specified in the IEC61076-2-010 standard.

DE 20 2016 10427121 describes a plug connector system in which at least one plug and one contact are arranged separately on a support body. The plug is held in the support body by the adapter.

DE 10 2018 122 848 A1 describes a module element for accommodation on a holding frame, on which an M12 plug connector is arranged.

Disclosure of Invention

The object of the invention is to provide a contact insert for a plug connector part which can be connected to a mating plug connector part, which makes it possible to assemble the connection for the data conductors in a simple, modular manner, while the assembly of the contact insert is also simple.

This object is solved by a body having the features of claim 1.

The contact insert therefore has at least one conductor plug connector connected to the electrical conductor, which has an insulator, a locking element for locking the at least one conductor plug connector to the mating plug connector part, and an actuating element which can be moved relative to the insulator to unlock the locking element. The at least one electrical contact element is arranged on the insulator. The module housing has at least one receiving opening into which an actuating element of at least one wire connector can be inserted for connection to the module housing.

The contact insert may be modularly formed with one or more contact modules, which are attached to the holding frame for this purpose. The possibility of using a wire connector connected to the electrical wires is achieved in this case on at least one contact module.

The conductor plug connector can be designed in particular according to the so-called push-pull principle and has a locking element for locking with a mating plug connector part when the plug connection is established and an actuating element for unlocking the locking element. Such a wire connector can be plugged into another wire connector of the mating connector part and, in the plugged state, can be locked with the other wire connector by means of a locking element. By actuating the actuating element, in particular by moving the actuating element relative to the insulator, the locking can be released, so that the wire connector can thereby be released from the mating connector part.

The wire plug-in connector (in the assembled state of the contact insert) is arranged on the contact module and is firmly connected to the contact module. For this purpose, the module housing of the contact module has a receiving opening in which the actuating element of the wire connector is received for connection to the module housing. For assembly, the wire connector can be attached to the module housing such that the actuating element is located in the receiving opening and is thus received therein.

By inserting the actuating element into the receiving opening of the module housing, a connection is achieved between the contact module and the wire plug connector. The conductor plug connectors can thus be arranged on the contact module, wherein the conductor plug connectors are already preassembled with the corresponding electrical conductors.

The wire plug connector may for example be a standardized wire plug connector, for example according to the IEC61076-2-010 standard.

By arranging the wire connector on the contact module in a preloaded and connected manner with the corresponding wire, the wire connector can be provided together with the wire by the manufacturer and then used by the user on the contact insert. In particular, when the wire connector is designed as a data plug on a data wire, the wire connector can thus be mounted on the contact plug in a prefabricated manner, for example together with the already manufactured electromagnetic shield, wherein the wire connector is inserted with the actuating element into the receiving opening of the module housing for connection with the contact module, and then the module housing can be attached to the holding frame for configuring the contact plug.

In one embodiment, the module housing has two housing parts which can be separated from one another in order to insert the wire connector into the receiving opening. The housing portions define a receiving opening therebetween. When the housing parts are attached to each other, the wire plug connector is accommodated in the accommodation opening between the housing parts, so that the actuating element is fixed between the housing parts and thus firmly connected with the module housing.

In one embodiment, the actuating element is formed by a sleeve which is displaceable relative to the insulating body in the actuating direction. In this case, the actuating element preferably enables the push-pull principle. For example, a contact insert with a wire plug connector arranged thereon may be attached to a corresponding counterpart plug connector part in the plug-in direction. The attachment can in particular be carried out (pushed) in the plugging direction. The actuating element can be moved relative to the insulating body in the plugging direction, so that the actuating element can be actuated, for example, counter to the plugging direction (pull), in order to release the connection in order to unlock the locking element in this way.

Due to its design as a sleeve, the actuating element surrounds the insulator on the outer circumference and has a substantially cylindrical basic shape.

In one embodiment, the actuating element has at least one form-fitting section for form-fitting connection with the module housing. In the position of insertion of the actuating element into the receiving opening of the module housing, the form-fitting section of the actuating element engages with a corresponding counter-form-fitting section on the module housing, so that a form-fitting connection is thereby formed between the actuating element and the module housing. The form fit can be provided in particular in a plug-in direction, in which the contact plug can be plugged into the mating plug-in connector part, so that the actuating element can be fixed in a form-fit manner relative to the module housing in the plug-in direction and cannot be moved independently of the module housing in the plug-in direction.

The actuating direction in which the actuating element is actuated is preferably oriented in the plugging direction, so that the actuating element can be moved relative to the insulating body in the plugging direction in order to unlock the locking element.

In one embodiment, the actuating element has a cylindrical body from which the at least one form-fitting section protrudes radially. The actuating element thus has a cylindrical basic shape. At least one form-fitting section protrudes radially from the cylindrical body, wherein the form-fitting section of at least one may be formed, for example, by an annular section encircling the body or any other radially protruding shape. In the position in which the actuating element is connected to the module housing, at least one form-fitting section engages with a mating form-fitting section of the module housing, for example in the form of a recess complementary to the form-fitting section of the actuating element, so that a form-fitting connection is thereby formed between the actuating element and the module housing.

When the wire connector is arranged on the contact module, a secure connection is established between the actuating element and the module housing by receiving the actuating element in the receiving opening of the module housing. This allows the actuating element to be moved only with the module housing relative to the insulator. The actuation of the actuating element is thus effected by a displacement of the module housing which is accommodated in the mounting position on the holding frame of the contact insert which in turn is firmly connected to the housing of the corresponding plug-in connector part.

When the plug connector part is plug-connected with the mating plug connector part, the wire plug connector on the contact module is plug-connected with the corresponding wire plug connector on the mating plug connector part. This creates a lock between the wire connectors, thereby securing the connection. If the connection is to be released, the user can activate the housing of the plug connector part and move it against the plug-in direction relative to the mating plug connector part, whereby the contact plug (too) is moved relative to the mating plug connector part with the holding frame and the module housing firmly connected to the holding frame. The actuating element of the wire connector is thereby actuated, so that the locking of the locking element is released, so that the wire connector is separated from the mating connector part according to the push-pull principle, so that the connector part can be removed from the mating connector part.

The actuating element is thus actuated by actuating the housing of the upper-stage plug connector part. Since the actuating element is fixed to the module housing of the contact module, which in turn is accommodated in a holding frame firmly connected to the connector part housing, actuation of the connector part housing is transmitted to the actuating element and results in unlocking. In this way, a plug connector part is obtained in which a lock is established by means of one or more wire plug connectors, wherein the lock can be released by moving the housing of the plug connector part as a whole according to the push-pull principle.

In one embodiment, the actuating element has an actuating section for acting on the locking element. By means of this actuating section, the actuating element acts on the locking element during actuation, for example by the actuating element pushing the locking element out of the locking position and thus unlocking it.

In one embodiment, at least one of the conductor plug connectors has an electrically conductive plug section arranged on the insulator, on which the actuating element is guided in a movable manner, and which can be connected in a plug-in manner to the mating plug connector part in order to transmit the ground potential. The plug section is electrically connected, for example, to a shielding layer of the conductor, so that the plug section forms a shielding layer on the side of the conductor plug connector and transfers the shielding potential to the mating plug connector part, in order to achieve uninterrupted shielding also at the transition between the conductor plug connector and the mating plug connector part.

The actuating element is guided displaceably on the plug section, so that the actuating element can be displaced on the plug section, in particular for unlocking the conductor plug connector.

In one embodiment, the locking element is electrically conductive and is electrically connected to the plug section. The locking element can be arranged in particular on the plug section so as to be directly connected to the plug section. The locking element is locked to the mating connector part, for which purpose the locking element rests against the mating connector part in the locked position. The ground potential for shielding can thus be transferred to the mating plug connector part, for example to the conductive plug section on the conductor plug connector of the mating plug connector part, by means of the conductive locking element.

In one embodiment, the locking element can be displaced elastically relative to the plug section by actuating the actuating element in order to unlock the locking element. The locking element can be designed, for example, by an elastic spring element, which in the locked position, with elastic pretensioning, rests against mating connector parts, for example, the plug sections of the conductor plug connectors of the mating connector parts, so that a defined electrical connection is established by the locking element in the plugged position for the transmission of the ground potential, and furthermore a mechanical locking is also established. By actuating the actuating element, the locking element can be elastically deflected at the plug section in order to unlock the lock in this way. For example, the locking element may have a resiliently deflectable locking leg, which the actuating element acts on during actuation, and the locking leg can be moved out of the locking position by the actuating element, so that the wire connector is released from the mating connector part.

In one embodiment, the holding frame has a frame opening into which at least one contact module can be inserted to form a contact insert. In this case, the module housing has a first latching element, while the holding frame has a second latching element. The first latching element and the second latching element are latched together at the location of the insertion of at least one contact module into the frame opening, so that the contact module is thereby secured in the frame opening of the holding frame. Thus, the holding frame may be modularly assembled with one or more contact modules by inserting the one or more contact modules into the frame opening of the holding frame. In the inserted position, the contact module is locked with the holding frame by means of latching elements on the module housing, so that a fixed connection is formed between the contact module and the holding frame.

The holding frame may provide a plurality of plug-in locations arranged side by side, for example in a side-by-side direction. The contact modules can be attached to these plug-in locations in order in this way to create a variably assembled contact plug, the variable plug-in face of which is determined by the contact modules.

If the contact insert is assembled by fitting the holding frame with one or more contact modules, the contact insert can be inserted into the housing of the plug connector part in order to complete the plug connector part in this way.

In one embodiment, such a plug connector part comprises a housing and a contact insert of the type described above accommodated in the housing. In the assembled state, the housing is fixedly connected to the holding frame of the contact insert. The housing encloses the contact insert from the outside, thereby providing mechanical protection for the contact insert. The housing may be made of metal or plastic. By enclosing the contact insert in a housing, a heavy-duty plug connector is in particular achieved, which can also be used in industrial environments and which can withstand loads and environmental influences during operation.

The plug connector is composed of a first plug connector part and a second plug connector part, which can be plugged into each other in a plug-in direction. The plug connector parts can each be designed in the manner described above and each have a contact insert with a holding frame and at least one contact module, and a wire plug connector arranged on the contact module.

Detailed Description

The plug connector 1 shown in fig. 1A to 1C in one embodiment has a first plug connector part 2 and a second plug connector part 3, which can be connected to one another in a plug-in manner in a plug-in direction E. The first plug connector part 2 is arranged, for example, on an electrical component, for example a switch cabinet, and is fastened to the device wall 21 for this purpose by means of the housing 20. On the other hand, the second plug connector part 3 is connected, for example, with a cable 31 which extends through the cable outlet 300 into the housing 30 of the plug connector part 3 and is fixed to the cable outlet 300 in a stress-relieving manner by means of a cable fixing means 301 in the form of a fixing nut.

The plug connector parts 2,3 in the exemplary embodiment shown in the figures in particular realize what is known as a heavy-duty plug connector (also referred to as an industrial plug connector), which is suitable for use in industrial environments and is designed to be loadable and durable for this purpose.

In the exemplary embodiment shown, the plug connector parts 2,3 each have a contact insert 4,5, which is enclosed in a respective housing 20, 30 of the plug connector part 2,3 and forms a plug face on the respective plug connector part 2,3 for plug-connecting the plug connector parts 2,3 to one another.

As can be seen from the sectional views according to fig. 1B and 1C, the contact inserts 4,5 are each formed by a holding frame 41, 51 and a contact module 40, 50 arranged thereon. On at least one contact module 40, 50 of each contact plug 4,5, a wire plug connector 6,7 is arranged, which is connected to the corresponding wire 60, 70 and has an electrical contact element 62, 72 for establishing an electrical connection between the plug connector parts 2, 3.

The first wire plug connector 6 is assigned to the first plug connector part 2 and is arranged on the contact plug 4 of the first plug connector part 2. On the other hand, a second wire plug connector 7 is assigned to the second plug connector part 3 and is arranged for this purpose on the contact plug 5 of the second plug connector part.

Fig. 2 shows two mutually corresponding, mutually complementary conductor plug connectors 6,7 in the plug-in position, but without the corresponding contact plug 4,5 and other components of the plug connector parts 2,3, respectively.

The first wire plug connector 6 is shown in different views in fig. 4-10. In contrast, the second wire connector 7 is shown in different views in fig. 11 to 15.

The wire connectors 6,7 are connected by way of a so-called push-pull principle. Each wire connector 6,7 has an insulator 61, 71 with an insulator section 610, 710, which protrudes in the direction of the other wire connector 7, 6, respectively, on which an electrical contact element 62, 72 is arranged. The contact elements 62 of the first wire plug connector 6 form socket contacts, into which the contact elements 72 of the second wire plug connector 7 in the form of pin contacts can be inserted for electrical contact.

The wire connector 6,7 together with the corresponding wire 60, 70 form a data connection. Each wire plug connector 6,7 has a plug section 63, 73 made of an electrically conductive material, which is connected to the shielding of the wires 60, 70 so as to be at ground potential of the shielding of the wires 60, 70. For plugging the conductor plug connectors 6,7, the plug sections 63, 73 are plugged into one another, the plug section 73, which is designed as a so-called male part, is engaged with the plug section 63, which is designed as a so-called female part, and a plug connection is thereby established between the conductor plug connectors 6, 7.

The wire plug connector 6 has a locking element 65 which is arranged as an annular element (see fig. 3 and 4) in the plug section 63 and projects radially inwards from the plug section 63 in a plurality of tongues arranged side by side in the circumferential direction around the plug section 63. By means of the locking element 65, a lock is established between the plug sections 63, 73 in the plug position of the wire plug connectors 6, 7. For the plug connection, the wire plug connectors 6,7 are plugged into one another in the plug direction E. In the process, the plug section 73 is slid into the plug section 63 in the plug direction E, so that in the plug position the plug section 73 of the second plug connector 7 is located behind the locking element 65 with the locking head 730, and thus the pulling out of the wire plug connector 7 counter to the plug direction E is prevented by the locking element 65. In the plugging position, the wire plug connectors 6,7 are thus locked together and cannot be released from each other against the plugging direction E, at least without unlocking.

In the plugged position, a moisture-tight transition is formed between the wire connectors 6,7 by means of one or more seals 630, so that moisture cannot enter in particular the region of the contact elements 62, 72 on the wire connectors 6, 7.

An actuating element 64 in the form of a substantially cylindrical sleeve is arranged on the plug section 63 of the wire plug connector 6, which actuating element can be displaced in an actuating direction B (which is oriented in the plug direction E) on the plug section 63. By moving the actuating element 64 in the actuating direction B, the actuating element 64 can be moved on the plug section 63, so that the actuating element 64 acts with the actuating section 640 on the tongue of the locking element 65 and moves it elastically relative to the plug section 63. The locking of the wire connectors 6,7 is released in this way, so that the wire connectors 6,7 can be disconnected from one another in the plugging direction E.

By making the wire connectors 6,7 insertable together (pushed) in the plugging direction E, the plug connectors 6,7 can then be released again from each other (pulled) by moving the actuating element 64 in the opposite, oriented actuating direction B, with the locking of the locking element 65 released, the plug connection being realized according to the push-pull principle. The wire connectors 6,7 are easily attached to each other, reliably locked together in the plugging position, and can be released again relative to each other by the user conveniently by unlocking them.

In the embodiment shown, the locking is effected by a locking element 65 on the wire plug connector 6 side. It should be noted that the wire connector 7 also has a locking element 75 and an actuating element 74 for unlocking the locking element 75, which enables connection with another wire connector and locking by means of the locking element 75. The locking element 75 and the actuating element 74 are provided in particular in order to also establish compatibility with other plug connectors.

The line connectors 6,7 are used in particular for establishing data connections, for example ethernet connections, and are designed for this purpose, for example, as four-pole connectors having so-called M12 plug faces. For example, the wire-plug connector may be standardized.

Since in such data connections the wire connectors 6,7 are to be connected, for example, with the shielding of the corresponding data wires 60, 70, such wire connectors 6,7 are usually provided to the user by the manufacturer in a mass-produced manner, after which the user uses the wire connectors 6,7 together with the already connected wires 60, 70 in a predetermined manner.

The invention proposes the use of a wire plug connector 6,7 on the plug connector parts 2,3, as shown for example in fig. 2, 4,5 and 11, which makes it possible to realize heavy-duty plug connectors (industrial plug connectors). For this purpose, the wire plug connectors 6,7 are attached to the corresponding contact modules 40, 50 and used on the contact modules 40, 50 without any adjustment of the plug connector parts 6,7 being required for this purpose. When the plug connector parts 2,3 are plugged, the conductor plug connectors 6,7 of the plug connector parts 2,3 are connected to one another in a plug-in manner, wherein a lock is respectively established on the conductor plug connectors 6,7, which can then also be released together again in a common manner by the actuation element 64 of the conductor plug connector 6 being actuated together.

As can be seen from the wire plug connector 6 of fig. 6-9 and the wire plug connector 7 of fig. 12-14, the contact modules 40, 50 for using the wire plug connectors 6,7 are formed by housing parts 400, 500 which have receiving openings 401, 501 for receiving the wire plug connectors 6,7 and can be attached to each other to complete the respective contact modules 40, 50. Fig. 9 shows such a contact module 40 using two wire plug connectors 6. Fig. 14, on the other hand, shows a contact module 50 using two wire plug connectors 7.

For each contact module 40, 50, the two housing portions 400, 500 are attached to each other to form a module housing 406, 506. The housing parts 400, 500 together form two receiving openings 401, 501, respectively, in each case in which a wire connector 6,7 can be received.

As can be seen from the wire connector 6 of fig. 4 and 5 in combination with fig. 6 and from the wire connector 7 of fig. 11 and 12, form-fitting sections 641, 741 are formed on the actuating elements 64, 74 of the respective wire connector 6,7, which project radially from the cylindrical bodies 642, 742 of the actuating elements 64, 74 formed as sleeves. The form-fitting sections 641, 741 are each formed as a surrounding annular section on the outside of the main body 642, 742 and engage into the corresponding form-fitting sections 402, 502 in the form of groove-shaped recesses inside the corresponding receiving openings 401, 501 of the housing parts 400, 500 in the plugging position of the wire plug connectors 6,7, so that a form-fitting connection is formed between the actuating elements 64, 74 and the module housings 406, 506 and the actuating elements 64, 74 are form-fittingly connected with the module housings 406, 506 in the plugging direction E.

The wire plug connectors 6,7 are thereby respectively accommodated and fastened to the corresponding module housing 406, 506. In this way, a contact module 40, 50 is formed, which is shown in fig. 9 for two conductor plug connectors 6 and fig. 14 for two conductor plug connectors 7.

Each contact module can now be inserted into the holding frame 41, 51 of the contact insert 4,5 to form the contact insert 4,5, as shown in fig. 10 for the contact insert 4 and fig. 15 for the contact insert 5. Since the contact modules 40, 50 with the conductor plug connectors 6,7 arranged thereon are mutually chargeable and can be connected to each other to establish an electrical (data) connection, complementary contact inserts 4,5 are created in this way, which can be connected to each other to connect the higher-level plug connector parts 2, 3.

As can be seen from fig. 10 and 15, each holding frame 41, 51 has a side frame part 410, 510 which are connected to one another by means of end flange sections 413, 414, 513, 514 and form a plurality of plug-in locations arranged next to one another for receiving the contact modules 40, 50. In this case, latching elements 411, 511 in the form of mechanical springs are arranged on the side frame parts 410, 510 for producing a locking connection with latching elements 405, 505 on the module housings 406, 506 of the contact modules 40, 50 when the contact modules 40, 50 are inserted into the frame openings 412, 512 of the holding frame 41. In the inserted position, the contact modules 40, 50 are thus firmly connected to the holding frames 41, 51 and are thus firmly and loadably fixed to the holding frames 41, 51.

To form the plug connector parts 2,3 (see fig. 1A-1C), the contact inserts 4,5 can be fastened to the housings 20, 30 by screwing the flange sections 413, 414, 513, 514 to the respective housings 20, 30 to connect the contact inserts 4, 5. The plug connector parts 2,3 are thus assembled, wherein a plug face is formed on the plug connector parts 2,3 by the contact modules 40, 50 on the holding frames 41, 51.

Because the actuating element 64, 74 of the wire connector 6,7 is fixed to the module housing 406, 506, the actuating element 64, 74 together with the module housing 406, 506 can be moved relative to the other components of the wire connector 6,7, in particular the assembly formed by the insulator 61, 71, the plug section 63, 73 and the locking element 65, 75. This achieves that the actuating elements 64, 74 of all the wire connectors 6,7 are actuated together by actuating the housings 20, 30, so that by attaching the connector parts 2,3 the wire connectors 6,7 can be plugged into one another in a simple manner and a lock can be produced by the wire connectors 6,7, but also by actuating the housings 20, 30 of the connector parts 2,3 the lock can be released, so that the connection can again be released simply.

As can be seen from fig. 16, the contact inserts 4,5 can be attached to one another in the plugging direction E. When attached, the wire plug connectors 6,7 lock with each other. If, in order to release the respective plug connector parts 2,3 from one another again, one of the plug connector parts 2,3 is pulled, the housing 20, 30 of the respective plug connector part 2,3 is moved, wherein this movement is transmitted via the housing 20, 30 to the holding frame 41, 51 and thus to the module housing 406, 506 of the contact module 40, 50. As a result of the fixed connection to the module housing 406, 506, the actuating element 64, 74 on the wire connector 6,7 is thus displaced, so that the locking of the wire connector 6,7 is released.

This enables a simple manipulation of the plug connector parts 2,3 to establish a connection and release a connection.

Because the module housings 406, 506 of the contact modules 40, 50 are adapted to accommodate the pre-manufactured, possibly standardized, wire-plug connectors 6,7, the wire-plug connectors 6,7 can be manufactured and delivered together with the connected wires 60, 70 and then can be attached to the module housings 406, 506 by the user so as to be usable on the contact modules 40, 50. This enables, in particular, the user to use already existing, mass-produced data lines on the contact modules 40, 50 in a variable, modular manner.

By adapting the shape of the receiving openings 401, 501 on the module housings 406, 506, the contact modules 40, 50 can be adapted to a specific wire connector 6,7, so that in principle completely different wire connectors 6,7 can be used on the contact modules 40, 50.

The basic idea of the invention is not limited to the embodiments described above, but can also be implemented in other ways.

The holding frame, the contact module and the wire plug connector may in particular have a completely different shape than described in the embodiments.

The data connection can advantageously be established by means of a wire connector, wherein the wire connector can be formed as monopolar, bipolar or multipolar, for example as quadrupole.

An ethernet connection, in particular a fast ethernet connection, can be established in particular by means of a wire plug connector of the type described here.
