Plug-in device

The invention relates generally to a connecting device. In particular, the invention relates to a Steckvorrich device for forming a connector.

There are connecting devices for forming connectors known. There are also connecting devices with "male union" and "female" connectors are known. The publication DE 29717055 U1 describes a connecting device with combined plugs and sockets, the connecting device having a first end formed as a socket connector and a second end designed as a connector connector. However, the known connecting elements are unwieldy and have a complex structure.

One object of embodiments of the present invention is therefore to provide an improved connector device.

To solve this problem, a connector for forming a connector is proposed. The plug-in device has a front end for connecting the plug-in device to an essentially similar plug-in device and a rear end for receiving a band-shaped body, in particular a cable. The connector comprises a housing with a front side at an open front end, with a rear side at an open rear end opposite the front end and with a side wall connecting the front side to the rear side, the side wall having at least one recess at the front end. The plug-in device further comprises a plug-in body or plug-in insert with a front side and with a rear side opposite the front side, the front side of the plug-in body having at least one gradation, and the plug-in body in the housing, in particular in the open front end of the housing, insertable in this way is that the at least one gradation of the plug body at the open front end of the housing is positioned essentially diametrically opposite the at least one recess of the housing, so that the front end of the plug device with a front end egg ner similar plug device to form a connector that can be held together by frictional forces can be connected by a translational movement.

Due to the design of the connector, in particular due to the positioning of the recess on the front of the housing and due to the gradation or the stepped area or the plug nose on the front of the Steckkör pers, the front end of the connector is separated into two funk tioneil areas. Because the gradation of the Steckkör pers can a non-stepped area of another plug body, in particular another connector, aufneh men. The non-stepped area of the plug-in body can, however, be included in a corresponding step of another plug-in body.

The plug device is thus equipped with the functionality of both a "male" and a "female" connection piece, so that a complementary or complementary plug connection with a similar or essentially identical plug device can be implemented in a simple manner without doing a rotary motion to have to perform in particular to screw in connectors or to secure the connector. Because of the possibility of connecting essentially identical plug-in devices, the plug-in device is also particularly well suited for standardization. In particular, the plug-in device can be used as a standard plug-in device or as a standardized universal connector, which realizes the double functionality "male-female" or pin socket.

The plug-in device can be designed to be essentially cylindrical, the at least one recess being formed in the form of a semicircle at the end of the housing, and the at least one step on the front side of the plug-in body being formed in a semicircle. Through the semi-ring-shaped recess of the housing and the semicircular graduation from the plug body, a secure plug connection with a similar plug device is easily made possible light, the correct orientation of the plug device at the position of the recess or the gradation is easily recognizable bar.

The plug-in device can have at least one friction element for increasing the frictional forces between two essentially identical plug-in devices which are connected to one another in a plug-in connection. Due to the increase in the frictional forces caused by the friction element, in particular the tensile force required to release the plug connection can be increased up to a predefined level, so that an unintentional loosening of the plug connection can be prevented.

The at least one friction element can comprise at least one O-ring, in particular a rubber O-ring. With an O-ring, the necessary to release the plug connection can be made Pulling force can be increased in a simple manner. Furthermore, the friction element can, however, also be formed in other conventional ways.

The inside of the housing can have, in particular, a circumferential groove for receiving the at least one O-ring. The O-ring can be secured through the groove so that the O-ring does not slip or fall out even if it is repeatedly inserted and removed. In particular, the plug connection between two plug devices can lead to a pinch or terminal contact caused by the O-ring or O-ring seal, whereby the plug connection is held together.

In some embodiments, a non-stepped loading area protrudes from the plug-in body, in particular when installed, from the front of the housing. The protruding from the housing part of the plug-in body can in particular serve as an orientation aid, so that two similar Steckvor directions can be plugged together easily and quickly.

In some embodiments, the plug device has at least one contact pin and at least one contact hole, the at least one contact pin and the at least one contact hole being arranged to be accessible from the front of the plug device or the housing.

The at least one contact pin accessible from the front of the connector and the at least one contact hole accessible from the front of the connector can be used to form an electrical contact so that the connector can provide both a mechanical and an electrical connection. The plug device can have an equal number of Kontaktstif th and of contact holes, so that the Steckvor direction is divided half into pins and sockets. In particular, the at least one contact pin and the at least one contact hole can be arranged complementary to one another, so that when two plug-in devices of the type described above are brought together, each contact hole is occupied by a corresponding contact pin, and each contact pin is received by a corresponding contact hole becomes. Such an arrangement of the at least one contact pin and the at least one contact hole allows a complementary electro-mechanical connection between two similar plug devices to be provided in a simple manner.

The at least one contact pin can in particular be arranged on the at least one gradation of the plug-in body and the at least one contact hole outside the gradation, in particular on a non-stepped part of the plug-in body or on the plug nose on the front of the plug element. By arranging the contact pins in the gradation, the contact pins can be protected particularly well by the outer wall of the housing.

Terminal contacts can be formed on the rear side of the plug-in body, which are electrically connected through the plug-in body to the at least one contact pin and to the at least one contact hole. The connection contacts on the rear side of the plug-in body can in particular be connected directly to opposite contact pins or contact holes and / or in a permutated manner, so that a desired pole assignment of the contact pins or contact holes is achieved. The invention will now be explained in more detail with reference to the accompanying figures. The same reference numerals are used in the figures for parts that are the same or have the same effect.
