Description

The invention is based on a connection element according to the preamble of the independent claim 1.

Such connection elements are needed to connect different connectors together.

State of the art

The DE 10 2013 105 602 A1 shows a connector for connectors for contacting the connector with a mating connector. In this case, the connection element is intended to produce a mechanical connection with a mating connection of the mating connector to be contacted. For this purpose, at least two types of means for contacting mating connections are provided on the connection element, which also allow many different types of mating connectors to be contacted with the connector. This allows use of the connector with various types of mating connectors.

A disadvantage of the known prior art, however, is that the known connection elements consist of at least two parts. Due to this multi-part design of the connection elements, the connection of different connectors is only partially possible, since the wealth of variants is limited.

task

The object of the invention is to propose a connecting element, which is carried out variant rich.

The object is solved by the subject matter of independent claim 1.

Advantageous embodiments of the invention are specified in the subclaims.

The invention relates to a connection element for plug connectors and mating connectors. The connection element has at least one interface for connecting plug-in connectors and mating connectors or for connecting plug-in connectors and circuit card. The connection element has a first connection side and a second connection side, wherein the first connection side and the second connection side are arranged opposite one another. The connection element furthermore has at least a first interface and a second interface. The first interface and the second interface are each suitable for connecting different connection variants of the mating connector or for connection to a printed circuit board.

A connection variant is understood to mean the type of housing of a connector or a mating connector to be connected. For example, there are so-called heavy-duty connectors, RJ connectors, PushPull connectors. The different types of housings have different mating faces, so that a variety of different connection variants in the prior art is known. These mating faces correspond with a corresponding mating connector face. Alternatively, the use of a connection element with different mating faces on connectors and mating connectors is necessary.

The connection element serves to establish a connection between plug connector and mating connector. In this case, connectors and mating connectors are either identical design or connectors and mating connectors are of different types. Ideally, the connecting element is used as a connector between different types of connectors.

The connection element has corresponding contacts. However, since the present invention relates only to the terminal, the connector and mating connector, the contacts are not of concern. The contacts will not be discussed further below.

In a particularly preferred embodiment, the connection element is integrally formed. The one-piece design ensures that connectors and mating connectors are securely and stably connected to each other. Due to the one-piece design, a possible predetermined breaking point is avoided or prevented, which increases the stability of the entire connection.

In a preferred embodiment, the connecting element is formed substantially sleeve-like. The sleeve-like shape is intended to receive the contacts such that, as described above, a first interface and a second interface result.

In a further embodiment, the connection element is designed as a hollow cylinder. The hollow cylinder is in the axial direction ideally composed of two hollow cylinders with different radii.

In a preferred embodiment, the first interface is suitable for connecting different connection variants. This preferably also applies to the second interface. This is ideally suitable for various connection variants.

Another embodiment states that the first interface and the second interface are each suitable for connecting differently sized conductor cross sections.

The first interface has nested connection variants. The second interface has nested connection variants. Due to the nested arrangement of the connection variants, a space-saving arrangement of the connection variant per interface is provided.

In a particularly preferred embodiment, the connection variants are each a snap-in connection and / or a PushPull connection and / or a screw connection and / or a connection for an at least single-pole plug and / or a connection to a printed circuit board , In particular, the connection variants are a combination of M12 screw connection, D12 PushPull connection, D12 snap-in connection, D8 PushPull connection and D8 snap-in connection. As a result, the variety of different types of connection elements is reduced. The connection element can be used universally.

The combination of snap-in connection, PushPull connection and screw connection means that the connection element corresponds to the IP classes IP20, IP65 / 67 and IP69K, for example.

The object is thus achieved by an inventive connecting element. The connecting element allows a simple connection of different connection variants and conductor cross sections without changing the same. Through the one-piece connection element, the necessary variety of connection elements is reduced, which is easier and clearer to handle in everyday life for the fitter. Furthermore, the connection element meets the requirements of various IP protection classes such as the IP20, the IP65 / 67 and the IP69K.
