Description

The invention relates to a mounting-friendly embodiment of an electrical angle connector.

Various embodiments of angular connectors are already known from the prior art. However, the installation of the angle plug, in particular the connection of the cable to the contact elements of the angle plug connector, usually is very cumbersome because the contact elements are difficult to access due to the shape of the angle connector.

The invention is therefore based on the object to overcome vorbesagte disadvantages and to provide an easy to install angle connector available, the contact elements are easily accessible during assembly which makes the entire assembly process easier than other angle connectors.

This object is achieved by the feature combination according to claim 1.

The invention therefore proposes an electrical angle plug connector with a two-part housing which can be connected to one another via a corresponding connecting section. The housing, which consists of a first housing part, which extends from a mounting side to its connecting portion in a first direction, and a second housing part, which extends in a direction transverse to the first direction second direction from its connecting portion to a plug-side portion, there is also from an adapter piece for insertion mounting in the second direction in the first housing part, and a contact body for receiving at least one contact element, wherein the adapter piece in its, in the first housing part completely inserted and mounted state, at least partially extends into the second housing part and wherein the contact body is releasably held by connecting means on the adapter piece and is fixed by means of the connecting means against axial displacement in the second direction. As a result, the simple installation of cables to the contact body is guaranteed and since it can be plugged separately into the housing, while the mounting location is easily accessible.

For the plug-in mounting, at least one profiled extension is provided on the adapter piece, which can be plugged into a corresponding groove of the first housing part. The reverse of this principle is, so the extension of the housing part and the groove on the adapter piece is also possible. Sliding surfaces may also arise between the profiled extension and the corresponding groove, so that the pairing forms a sliding bearing.

It is advantageous if the adapter piece at least partially has a C-shaped contour in which it receives the contact body. As a result, the two wing-shaped arms of the adapter piece arch around the contact body whereby this is held in the radial direction to its longitudinal axis in its position until final assembly.

It is also advantageous if the connecting means between contact body and adapter piece are formed as a groove on the contact body and corresponding to the groove as engaging in the groove projection on the adapter piece, or vice versa. As a result, the contact body is fixed in position until final assembly.

An advantageous embodiment is characterized in that the groove is formed on the adapter piece as an upwardly open groove. The groove can thus follow the entire C-shape of the adapter piece or be formed only in parts of the C-shape, while it is also possible that the groove is designed as a breakthrough, so completely breaks through the wall of the C-shaped adapter piece. The projection on the contact body can, corresponding to the formation of the groove on the adapter piece, completely circumscribe the outer jacket of the contact body or else be formed only partially on the outer jacket.

It is advantageous, in the embodiment of the groove on the contact body, an embodiment in which the groove is annularly formed on the contact body annular.

Furthermore, an advantageous embodiment is provided if at least one coding groove or coding rib extends from an end face of the contact body starting in the second direction and is provided at least one position on the outer shell of the contact body, wherein a contact body counterpart has at least one corresponding coding rib or coding groove. It is true that between two coding grooves always a coding rib is formed. By such a coding a faulty connection is prevented, which increases the handling and reliability.

In this case, a possible embodiment provides that the adapter piece represents a contact body counterpart. That is also present at the adapter piece at least a corresponding Kodiernut or Kodierrippe to those on the contact body. If there are several coding grooves or coding ribs on the contact body, but only one on the adapter piece, the adapter piece can thereby be in its rotational position adjusted and fixed relative to the adapter piece.

An advantageous embodiment is when a two-part cable duct is formed from the mounting side to the plug-side portion, wherein a first cable duct part through the first housing part from the mounting side to the connecting portion and a second cable duct part through the second housing part of the connecting portion in the direction of the plug-side portion of second housing part extends. The cable duct serves both for receiving cables and for their guidance. A cable guide can be given by an inner contour of the housing walls, which facilitate insertion and passage of the cables through the housing.

It is positive and therefore advantageous if a first seal is provided between the contact body and the second housing part. As a result, the interior of the housing is protected from dust, other dirt and up to a certain pressure limit against fluids.

It is also advantageous if between the first housing part and the second housing part, a second seal is provided, preferably, the seal is mounted in a, on the outer surface of the first housing part introduced groove-shaped, recording. As a result, the housing is also sealed at its joint against dust, dirt and up to a certain pressure limit against fluids.

An advantage, in particular for harsh environmental conditions, is when the two-part housing comprises metallic material. This makes it stronger and more resilient.

The installation of such an electrical angle connector can be done with the following steps:

• Passing one or more cables through the cable duct from the mounting side of the first housing to the connecting portion of the first housing;
• • Connecting one or more cables to the at least one contact element and inserting the contact elements on the end or latching position in the contact body;
• • Inserting the contact body in its mounting position in the adapter piece such that the contact body is held by the connecting means and subsequent mounting of the adapter piece on the first housing part, so that the contact body is connected via the adapter piece with the first housing part, or alternatively insert the adapter piece in the Mounting position in the first housing part and subsequent mounting of the contact body on the adapter piece, so that the contact body is held by the connecting means;
• Pushing the second housing part over the contact body until the connecting sections lie on one another such that the first seal tightly seals between the second housing part and the contact body and the second seal between the first housing part and the second housing part;
• • Attach the second housing part to the first housing part. This can be done by screwing the second housing part on the first, clipping the housing parts into each other or by equivalent measures.
