Description

Technical Field

[0001] The invention relates to an angled plug connector for fixing on a shielded conductor and also relates to a method for fixing the angled plug connector on a shielded conductor. Background Art

[0002] In particular, in the field of electric vehicles, the demands on charging cables and the associated plug connectors are increasing. In order to withstand environmental influences and enable charging outdoors, these plug connectors must meet the highest sealing requirements. In this case, the plug connector can preferably be designed with an angled wire outlet to ensure space-saving cable laying and convenient operation. However, the assembly of the connector on the cable, especially in the case of multi-pole wires with angled wire outlets, has not been able to be carried out in a satisfactory manner so far. Therefore, there is a need for an improved angled plug connector for fixing on shielded wires, which enables a simplified installation process. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to provide an improved angled plug connector which can be simply fixed on a conductor.

[0004] This technical problem is solved by the subject matter of the independent claim. Advantageous developments of the invention are given in the dependent claims, the description and the drawings.

[0005] The described embodiments are also applicable to an angled plug connector for fixing to a shielded conductor and a method for fixing an angled plug connector to a shielded conductor. Even without detailed description, different combinations of the embodiments can produce synergistic effects.

[0006] In addition, it is worth noting that all embodiments of the present invention related to the method can be performed in the described order of steps. However, this may not be the only possible and necessary order of steps in the method. Unless otherwise clearly stated below, the method described herein can be performed in a different order than the disclosed steps without departing from the corresponding embodiment of the method.

[0007] According to one aspect of the present invention, an angled plug connector for fixing on a shielded conductor is provided. The plug connector has an upper housing part and a lower housing part. The upper housing part has a hole configured to receive the conductor, wherein the hole is configured to allow the upper housing part to pivot around the conductor and to move the upper housing part along the conductor. The lower housing part is configured to receive at least one plug contact attached to the end of the conductor. In addition, the plug connector has a latching mechanism, which is configured to connect the upper housing part to the lower housing part.

[0008] Therefore, the plug connector has a two-piece outer housing, wherein the advantageous separation between the two housing parts allows a simple assembly of the components in the plug connector and a simple installation on the wire. The structural form of the plug connector can advantageously meet high or highest sealing requirements, such as IP6K9K. It is also possible when using a right-angle or almost right-angle wire outlet (preferably a 90-degree wire outlet). Through the structural form of the two-piece plug connector, wherein the upper housing has a hole on its rear end that is used as a through-guide for the wire and can be moved on the wire and laterally pivoted to the wire when the wire is introduced, a simple and reliable installation of the plug connector on the wire is guaranteed. Here, the hole can have a circular diameter that is slightly larger than the outer diameter of the wire to be assembled. Movement and pivoting can thus be achieved. Alternatively, the hole can also have other cross sections, such as elongated or elliptical cross sections. The lower housing part is constructed to be tightly connected to the side of the upper housing part opposite to the hole. For this purpose, a latching mechanism is provided between the upper housing part and the lower housing part. There is a hollow space between the lower housing part and the upper housing part, and the hollow space is used to receive at least one plug contact attached to the end of the wire. The plug contact is fixed in the lower half housing, and preferably protrudes from the lower half housing so that electrical contact can be generated when the plug connector is connected. Therefore, although the plug connector has an angled wire outlet, the plug connector is still assembled simply and fixed simply on the wire, and high sealing is ensured to prevent the intrusion of liquids such as water. Preferably, the plug connector is a multi-pole plug connector with a plurality of plug contacts, which can be attached to the individual cores of the wire. In a preferred embodiment, it is related to a plug connector provided for use in a high voltage field and / or configured for operation with an alternating current. Advantageously, the plug connector can be provided with a shielding member used with a shielded wire. The plug connector can be advantageously used in all multi-piece plug connectors here. Different variants of the plug system can be realized with the plug connector according to the present invention, such as outlet direction, number of poles, shielding or lead wire.

[0009] In one embodiment of the invention, the plug connector has a sealing device, which is designed to seal the upper housing part relative to the lower housing part. This sealing device can be attached to the connection point between the upper housing part and the lower housing part and can be designed as a circumferential rubber seal. Alternatively, a casting can also be provided to seal the two housing parts to each other.

[0010] In one embodiment of the invention, the plug connector has a contact support, which is configured to receive at least one plug contact attached to the end of a conductor and is configured to be received in the lower housing part. The contact support can serve as a connection between the at least one plug contact and the lower housing part. Thus, the plug contact attached to the conductor can be inserted into the contact support, and the contact support is attached in the lower housing part. As a result, in the case of a plurality of multi-pole plug contacts, a particularly simple installation can be achieved.

[0011] In one embodiment of the invention, the plug connector has a shielding element which is designed to be fixed with a first end to the contact support and with a second end to the conductor. To ensure uninterrupted shielding of the conductor of the conductor, the plug connector in this embodiment of the invention can be provided with a shielding element which extends the shielding of the conductor to an area within the plug connector. The shielding element can here be in contact with the shielding of the conductor and extend as far as the contact support or even further.

[0012] In one embodiment of the invention, the shield is constructed in two parts, so that the conductor runs between a first part of the shield and a second part of the shield. The two-part construction of the shield allows for a simple installation of the shield on the conductor that is already connected to the contact support. To this end, the two parts of the shield are attached to the conductor from opposite sides and connected to each other.

[0013] In one embodiment of the present invention, the shield is configured to be connected to the second end of the shield of the conductor. This ensures electrical contact of the shield and thus ensures grounding of the plug connector shield and / or the conductor shield.

[0014] In one embodiment of the invention, the plug connector further comprises a sealing portion, which is configured to seal the wire extending through the hole of the upper housing part relative to the upper housing part, and a tension relief portion, which is configured to prevent the wire from moving through the hole of the upper housing part when fixed to the upper housing part. In addition, the plug connector has a sealing cover, which is configured to be fixed to the upper housing part and thereby fix the sealing portion and the tension relief portion to the upper housing part. These components of the plug connector can be pushed onto the wire before the upper housing part is installed on the wire. After the upper housing part is connected to the lower housing part, the sealing portion can be pushed along the wire and installed in the hole of the upper housing part to seal the intermediate space between the wire and the upper housing part. The tension relief portion is then spliced ​​on the upper housing part and fixed to the upper housing part and clamped on the wire by the sealing cover.

[0015] In one embodiment of the invention, the plug connector is designed to bend the wire extending through the plug connector between the hole in the upper housing part and the plug contact attached to the end of the wire by substantially 90°. Preferably, the end of the wire is deflected by an angle of between 45 and 135 degrees in the plug connector, particularly preferably by an angle of between 80 and 100 degrees. Also particularly preferred are embodiments of the plug connector in which the wire is deflected by an angle of approximately 90 degrees.

[0016] In one embodiment of the invention, the bending of the conductor takes place essentially in the region of the shield of the plug connector, and the shield is designed to shield and / or stabilize the conductor without outer insulation running inside the shield. The deflection of the conductor takes place in the region in which the outer insulation of the conductor has been removed and the individual conductors of the multi-pole conductor run freely side by side. This region is particularly easy to deflect and can be stabilized and shielded from electromagnetic interference by the shield of the plug connector.

[0017] According to another aspect of the invention, a method for fixing an angled plug connector according to one of the aforementioned embodiments to a shielded conductor is proposed. The method comprises the following steps: plugging a sealing cover, a strain relief part and a sealing part onto the shielded conductor, and introducing the conductor into the upper housing part through a hole in the upper housing part. In addition, the method comprises the following steps: removing insulation from the end of the conductor, coating the shield on the conductor, attaching at least one plug contact to the end of the conductor, installing at least one plug contact into a contact support, and fixing the shield with a first end to the contact support and with a second end to the conductor. In addition, the method comprises the following steps: installing the contact support in the lower housing part, pivoting the upper housing part to connect the upper housing part to the lower housing part, and installing the sealing part, the strain relief part and the sealing cover on the upper housing part. This method enables a particularly simple and reliable attachment of the plug connector to the conductor.

[0018] Therefore, advantages provided by one of the above-mentioned aspects also apply to all other aspects, and vice versa.

[0019] Basically, the invention relates to an angled plug connector for fixing on a shielded conductor. The plug connector has an upper housing part and a lower housing part. The upper housing part has a hole configured to receive the conductor, wherein the hole is configured to allow a pivoting movement of the upper housing part around the conductor and a movement of the upper housing part along the conductor. The lower housing part is configured to receive at least one plug contact attached to the end of the conductor, and the plug connector has a latching mechanism, which is configured to connect the upper housing part to the lower housing part.
