Fixed-pole contact insert and contact insert arrangement

The invention relates to a fixed-pole contact insert for a plug connector, with a contact insert body and with a plurality of contact elements arranged in the contact insert body. In addition, the invention relates to a contact insert arrangement for a plug connector, with a fixed-pole contact insert, the fixed-pole contact insert having a contact insert body and a plurality of contact elements arranged in the contact insert body.

A large number of contact inserts for plug connectors in which several contact elements are arranged are known from the prior art. The

Contact inserts are usually arranged in a housing part of a plug connector that is designed to receive the contact insert.

For this purpose, the contact insert body is usually connected to the housing part of the

Connector connected. The contact inserts serve to be connected to a corresponding mating contact insert, which is arranged in a housing of a mating connector.

The contact elements arranged in the contact insert body can be designed, for example, as contact pins or contact sockets, which are connected to corresponding contact elements of the mating contact insert when the contact insert is plugged together with a corresponding mating contact insert or the plug connector is plugged together with the corresponding mating plug connector. By putting them together they become

Contact elements contacted collectively. The contact elements arranged in the contact insert body are known from the prior art

Connectors are designed similarly in terms of the contacting and connection zone in order to ensure uniform contacting.

Basically, contact inserts can be divided into modular contact inserts and fixed-pole contact inserts. Modular contact inserts are usually first inserted into a holding frame, which is then inserted into a housing part of a connector and secured therein. Because the contact inserts can be inserted individually into the holding frame, it is possible to equip a holding frame with different contact inserts depending on the intended use.

-2- BE2022/5306

Fixed-pole contact inserts, on the other hand, are inserted directly into a housing part of a plug connector and secured therein, i.e. without the use of a holding frame. Such a contact insert has a contact insert body in which several contact elements are arranged. With fixed-pole contact inserts, the number of contact elements arranged in the contact insert body cannot be changed. The present invention relates to fixed-pole contact inserts which are intended to be inserted and secured directly into a housing part of a connector without the use of a holding frame.

As a rule, the contact inserts, in particular the fixed-pole contact inserts in question, usually have at least one contact element in addition to the contact elements arranged in the contact insert body

Protective conductor and/or ground connection. So when it comes to the fixed-pole contact insert according to the invention, it is said that the fixed-pole

Contact insert has contact elements arranged in the contact insert body, then the at least one protective conductor and / or ground connection does not fall under these contact elements but is to be considered separately from these contact elements. The holding frames of the modular contact inserts listed above also usually have at least one

Protective conductor and/or ground connection. Such a holding frame for a modular contact insert can be clearly distinguished from a fixed-pole contact insert in question, which, in addition to at least one protective conductor and/or ground connection, has further contact elements arranged in the contact insert body.

Various types of fixed-pole contact inserts are known from the prior art. These can be particularly in the type and the

The number, but also the arrangement, of the contact elements arranged in the contact insert body differ. However, what all fixed-pole contact inserts have in common is that the use of the fixed-pole contact inserts is limited and not flexible due to the contact elements that are firmly integrated into the contact insert body.

The present invention is therefore based on the object of providing a fixed-pole contact insert which can be used for a wider range of applications than conventional fixed-pole contact inserts. In addition, the invention is based on the object of providing a contact insert application.

-3- BE2022/5306 regulations that can be designed flexibly for different areas of application.

This object is achieved in the contact insert according to the invention with the features of patent claim 1 in that the contact insert body has at least a first receiving location for receiving at least one modular contact insert. According to the invention, it has been recognized that the range of use of a fixed-pole contact insert is significantly expanded can be made if the contact insert body has at least one receiving location for receiving at least one modular contact insert. The fixed-pole contact insert according to the invention can thus be equipped with at least one, in particular with several, modular contact inserts. In this way, the fixed-pole can be used in a particularly elegant way

Contact insert can be expanded to include further contact elements, namely the contact elements of the modular contact insert. In particular, the fixed-pole contact insert according to the invention enables easy adaptation to various areas of application and can therefore be used in a variety of ways and designed flexibly. The contact insert according to the invention also enables various types of contacts in a particularly elegant manner

Contact inserts can be flexibly combined with one another, namely in that a modular contact insert with a different design - in relation to the type and/or arrangement of the contact elements - can be inserted into at least one first receiving location. In order to enable a modular contact insert to be easily accommodated, A preferred embodiment of the contact insert according to the invention is characterized in that the at least one receiving location has a holding frame for receiving the at least one modular contact insert. In a first

Variant, the holding frame is designed as a separate component. The holding frame is then arranged in the receiving location and connected to the contact insert body. The connection between the holding frame and the contact insert body can be made, for example, by a screw connection or a

Snap connection can be realized.

In order to fix the at least one modular contact insert in the holding frame, in a preferred embodiment the holding frame has at least one spring element which is designed to fix the modular contact insert. The spring element preferably goes into a prestressed state, at least briefly, when the modular contact insert is inserted

-4- BE2022/5306 about. If the modular contact insert is arranged in its end position in the receiving location, the at least one spring element is preferably in a state with at least reduced preload compared to the state of maximum preload achieved. The at least one spring element is then particularly preferably in a relaxed state.

In order to fix the at least one modular contact insert in the holding frame, the spring element preferably has at least one latching element.

The latching element is preferably designed as a latching lug or as a latching projection. A modular contact insert, which is intended to be accommodated in the receiving location, then preferably has a locking recess into which the at least one locking element engages when the modular contact insert is inserted.

The holding frame particularly preferably has at least one second spring element for fixing a modular contact insert. Particularly preferably, the holding frame has at least a first end face and a second end face opposite the first end face, as well as a first long side and a second long side opposite the first long side, and the two spring elements are also on opposite sides

Sides of the holding frame are arranged, i.e. on the opposite end faces or on the opposite long sides.

The design with a holding frame designed as a separate component, which is connected to the contact insert body, has the advantage that different types of holding frames can be introduced into the contact insert body. In addition, the holding frame is replaceable, so that, for example, in the event of damage to the holding frame, only the

Holding frame can be replaced.

In order to reduce the effort associated with mounting the holding frame in the receiving location, in a particularly preferred embodiment of the fixed-pole contact insert according to the invention, the holding frame is at least partially formed in the contact insert body. The holding frame is therefore at least partially formed in one piece with the contact insert body, i.e. formed in the contact insert body in the area of the receiving location.

Particularly preferably, the holding frame formed in the receiving location has at least one spring element for fixing the at least one modular contact insert in the receiving location. Is particularly preferred

-5- BE2022/5306 the at least one spring element is formed in one piece with the contact insert body. The spring element preferably changes into a prestressed state, at least briefly, when the modular contact insert is inserted. If the modular contact insert is arranged in its end position in the receiving location, the at least one spring element is preferably in a state with at least reduced preload compared to the state of maximum preload achieved. Particularly preferably, the at least one spring element is then in a relaxed state,

To fix the at least one modular contact insert in the holding frame formed in the receiving location, the spring element preferably has at least one latching element, particularly preferably a latching lug or a latching projection. A modular contact insert then preferably has a locking recess into which the at least one locking element engages when the modular contact insert is inserted.

In a particularly advantageous embodiment, which further reduces the assembly effort, the holding frame is formed completely in the contact insert body. No additional separate fixing means are therefore necessary to fix the modular contact insert.

In one embodiment, the holding frame formed in the contact insert body in the area of the receiving location has at least one second spring element for fixing a modular contact insert. Particularly preferably, the holding frame has at least a first end face and a second end face opposite the first end face, as well as a first

Long side and a second long side opposite the first long side and the two spring elements are also formed on opposite sides of the holding frame, i.e. on the opposite end faces or on the opposite long sides.

The contact insert body of the fixed-pole contact insert can be implemented differently according to the invention. In a first variant, the contact insert body is made of an electrically insulating material. The contact insert body is particularly preferably made of a plastic.

This enables, for example, the production of the contact insert body using an injection molding process. The use of an electrically insulating material for the contact insert body has the advantage that

Contact elements of the contact insert body are electrically isolated from one another

-6- BE2022/5306 and that electrical insulation is also guaranteed compared to a modular contact insert that can be accommodated in the receiving location. If the contact insert has a protective conductor connection and/or a ground connection, in a particularly preferred embodiment at least one electrical contacting element for electrically contacting a modular contact insert that can be accommodated in the receiving place is arranged between the protective conductor connection and/or ground connection and the receiving place. If a modular contact insert is arranged in the receiving location, it is contacted by the electrical contacting element.

In an alternative embodiment, the contact insert body is made of an electrically conductive material. The contact insert body is particularly preferably made of a metal. An electrical connection between a modular contact insert that can be accommodated in the receiving location and a protective conductor connection and/or a ground connection of the

The contact insert then takes place via the electrically conductive contact insert body.

Particularly preferably, the contact elements of the fixed-pole contact insert are at least partially arranged in a contact element area. Further preferably, the contact element region of the fixed-pole contact insert has a contact element region longitudinal axis. With fixed-pole contact inserts known in practice, this is the case

The contact element area longitudinal axis is usually parallel to a long side of the contact insert or the contact element area longitudinal axis is parallel to an end face of the contact insert.

According to the invention, the at least one receiving location has a longitudinal axis of the receiving location. The receiving location is preferably dimensioned such that it has a greater extent in the direction of the longitudinal axis of the receiving location than in a direction perpendicular to the longitudinal axis of the receiving location. In one embodiment, the extension of the recording space in the direction corresponds

-7- BE2022/5306 tion of the longitudinal axis of the recording space, the extension of the recording space in a direction perpendicular to the longitudinal axis of the recording space. The recording space is then essentially square. According to the invention, it is now provided in a variant that the contact element area longitudinal axis and the receiving location longitudinal axis run parallel to one another. In an alternative variant, it is provided that the longitudinal axis of the contact area and the longitudinal axis of the receiving location run perpendicular to one another.

Through these inventive alignments of the receiving location to those - or at least to some - arranged in the contact insert body

Contact elements make it possible to equip the fixed-pole contact insert with at least one modular contact insert in a space-saving and clear manner.

Particularly preferably, the contact insert body has two end faces opposite one another and two long sides opposite one another. Further preferably, the at least one receiving location is formed on an end face of the contact insert body. This is particularly preferred

The longitudinal axis of the receiving location is parallel to an end face plane spanned by the at least one end face. In another embodiment, the longitudinal axis of the recording location is perpendicular to that of the at least one

Front side spanned front side plane.

In an alternative embodiment, the at least one receiving location is formed on a long side of the contact insert body. Particularly preferably, the longitudinal axis of the receiving location lies parallel to a longitudinal side plane spanned by the at least one longitudinal side. In another embodiment, the longitudinal axis of the receiving location is perpendicular to the longitudinal side plane spanned by at least one longitudinal side.

In a particularly preferred variant of the fixed-pole contact insert according to the invention, the at least one first receiving location is designed to accommodate several modular contact inserts. Particularly preferably, the plurality of modular contact inserts can be arranged directly adjacent to one another in the receiving space. More preferably, the multiple modular contact inserts can be fixed independently of one another in the receiving location, for example by previously described spring elements, so that the multiple modular contact inserts are individually in the

Recording place can be introduced or removed from the recording place.

A particularly preferred embodiment of the fixed-pole contact insert according to the invention, which further increases the modularity of the contact insert, is characterized in that the contact insert body has at least one second receiving location for receiving at least one further modular contact insert.

In an alternative variant, the first longitudinal axis of the recording space and the second longitudinal axis of the recording space are perpendicular to one another.

If the contact insert body has a first end face and a second end face opposite the first end face as well as a first long side and a second long side opposite the first long side, then in a particularly preferred embodiment the first receiving location is formed on the first end face and the second receiving location is formed The second

Front side formed. In an alternative variant, both are the first

Receiving place and the second receiving place are formed on the first end face. The longitudinal axes of the receiving location can then, for example, lie parallel to an end face plane spanned by the first end face or be perpendicular to an end face plane spanned by the first end face.

In a further variant, the first receiving location and the second receiving location are formed on a first longitudinal side of the contact insert body. Particularly preferably, the longitudinal axes of the receiving space then lie parallel to a longitudinal side plane spanned by the first longitudinal side or are parallel to the longitudinal side plane spanned by the first longitudinal side. It is also provided in one embodiment that the first receiving location is formed on the first long side and the second receiving location is formed on the second long side.

In a further alternative, the first receiving location is formed on an end face and the second receiving location is formed on a long side.
