It is known to configure an HSD circuit board plug (HSD-high speed data) and a USB circuit board plug (USB-universal serial bus) on a circuit board (PCB-printed circuit board) and electrically connect the plugs to each other via the circuit board. In this way, an adapter from the HSD interface to the USB interface is made possible.

Disclosure of Invention

The object of the invention is to improve a plug adapter of the type mentioned above in that it can be converted in a simple and functionally reliable manner from one electrical interface to an interface constructed in a different geometry.

This object is achieved according to the invention by the plug adapter described below. Advantageous embodiments of the invention are described below.

In a plug adapter of this type, it is provided according to the invention that the at least one first inner conductor part and the one second inner conductor part are in each case designed in one piece with one another.

This has the advantage that a particularly economical and simple to manufacture plug adapter with improved signal transmission is provided.

Since the at least one first outer conductor part and the one second outer conductor part are constructed integrally with each other, a further improvement of the signal transmission with continuous shielding of the signal conductor is obtained.

A particularly universally usable plug adapter is obtained in that the first electrical interface comprises four first inner conductor parts and the second electrical interface comprises four second inner conductor parts, wherein each of the four first inner conductor parts of the first interface is configured to be integrated with one second inner conductor part of the second interface, respectively.

Since the first electrical interface and the second electrical interface have the same number of inner conductor parts, a particularly simple and direct signal transmission between the plug-side ends of the plug adapter is obtained.

Since the first electrical interface comprises N₁An inner conductor part, wherein N₁Not less than 3, in particular N₁=4, said N₁Each of the inner conductor members has a first plug-side end portion, wherein the first plug-side end portions of the first inner conductor members are arranged in N in one plane₁The corners of the polygon, a mechanical interface geometry is obtained where the first interface is circular in cross-section.

For example, the first electrical interface includes a first outer conductor member configured to be circular or elliptical in cross-section. The first electrical interface is thus adapted to a corresponding circular or elliptical interface contour.

Since the second electrical interface comprises N₂An inner conductor part, wherein N₂Not less than 3, in particular N₂=4, said N₂Each inner conductor part has a second plug-side end, wherein the second plug-side ends of the second inner conductor parts are arranged on a straight line in a plane, resulting in a mechanical interface geometry of the second interface with a substantially rectangular or polygonal cross section.

For example, the second electrical interface has a second outer conductor member that is rectangular or polygonal in cross-section. In this way, the second electrical interface is adapted to a corresponding rectangular or polygonal interface contour.

By way of example, the first electrical interface is configured as an HSD (HSD-high speed data) interface.

In a preferred embodiment, the second electrical interface is configured as a USB interface.

Since the plug-side end of the at least one first inner conductor part is configured as a pin, an electrical plug is obtained in which the first interface is simple to manufacture.

Since the plug-side end of the at least one second inner conductor part is configured as a resilient sheet metal part, an electrical plug is obtained in which the second interface is simple to manufacture.

A particularly simple and economical production is achieved in that the at least one integral inner conductor part is constructed as a stamped and bent part from the first inner conductor part and the second inner conductor part.

In order to fix the first inner conductor part of the first interface locally to the first plug-side end of the plug adapter, the first interface comprises a first insulator, to which the first inner conductor part is held and which is arranged within the first outer conductor part.

In order to fix the second inner conductor part of the second interface locally to the second plug-side end of the plug adapter, the second interface comprises a second insulator, to which the second inner conductor part is held and which is arranged within the second outer conductor part.

Detailed Description

The preferred embodiment of the plug adapter according to the invention shown in fig. 1 to 3 comprises a first plug-side end 10 and a second plug-side end 12. As shown in particular in fig. 1 and 3, the first plug-side end 10 is configured as a first electrical interface with a first mechanical interface geometry in the form of an HSD (high speed data) interface. The first electrical interface at the first plug-side end 10 therefore has four inner conductor parts 14 and a first outer conductor part 16. As is apparent in particular from fig. 2 and 3, the second plug-side end 12 is designed as a second electrical interface with a second mechanical interface geometry in the form of a USB interface, which is different from the first mechanical interface geometry. The second electrical interface at the second plug-side end 12 therefore has four second inner conductor parts 18 and four second outer conductor parts 20. The first outer conductor part 16 and the second outer conductor part 20 are constructed integrally with each other.

The preferred embodiment of the plug adapter shown in fig. 1-4 is merely exemplary and is shown with an HSD interface and a USB interface for simplicity of description. The terms "HSD interface" or "HSD plug" and "USB interface" or "USB connector" are merely representative of all possible interface or mechanical interface geometries or plugs or connectors.

Furthermore, the plug adapter according to the invention comprises a housing 22, which housing 22 is configured with the mechanical geometry of an HSD plug at the first plug-side end 10 and with the mechanical geometry of a USB connector at the second plug-side end 12. The first inner conductor part 14 and the first outer conductor part 16 also have the mechanical geometry of an HSD plug at the first plug-side end 10. Furthermore, the second inner conductor part 18 and the second outer conductor part 20 at the second plug-side end 12 have the mechanical geometry of a USB connector.

The first inner conductor component 14 is configured at the plug-side end 24 as a contact pin, so that said pin can be mechanically inserted into and make a corresponding electrical contact with a corresponding HSD connector (not shown). The second inner conductor part 18 is designed at the plug-side end 26 as a resilient sheet metal part, so that said part can be mechanically plugged together with a corresponding USB plug (not shown) and makes corresponding electrical contact with a contact surface in the USB plug.

The first interface at the first plug-side end 10 is configured with a first insulating member 28, which first insulating member 28 is arranged inside the first outer conductor member 16 and holds the first inner conductor member 14 fixed at a predetermined position. The first inner conductor component 14 is configured to be arranged around a ring line according to the mechanical interface geometry of the HSD interface, wherein the first outer conductor component 16 is configured to be circular in cross-section and to surround the first inner conductor component 14 configured in a star quad configuration as a shield. At the second plug-side end 12, the second interface is configured with a second insulating member 30, the second insulating member 30 being arranged within the second outer conductor member 20 and holding the second inner conductor member 18 fixed at a predetermined position. According to the mechanical interface geometry of the USB interface, the second inner conductor part 18 is configured such that its plug-side end 26 is arranged along a straight line in one plane, wherein the second outer conductor part 20 is configured rectangular in cross section and surrounds the second inner conductor part 18 as a shield.

The first inner conductor part 14 and the second inner conductor part 18 are in each case constructed together as a one-piece inner conductor part. In this way, a direct electrical connection is produced between the individual connections of the two different interfaces at the individual plug-side ends 10, 12 of the plug adapter without the need for circuit boards or other auxiliary components.

In order to be able to correctly distribute the signals transmitted via the inner conductors 14, 16 to the respective connections of the first and second interfaces, the respective integral inner conductor parts 14, 16 are configured differently in their mechanical path throughout the plug adapter, as shown in fig. 4. The circular geometry of the HSD interface is converted to a planar or flat geometry of the USB interface. The integral inner conductor parts 14, 16 are configured as sheet metal parts and are manufactured, for example, by means of a stamping-bending process by means of a further stamping step.
