• - eine USB-Buchse montierbar an der Leiterplatte; und
• - ein Stabilisierungselement montierbar an der Leiterplatte, wobei das Stabilisierungselement die USB-Buchse zumindest abschnittsweise umschließt, und wobei die USB-Buchse und das Stabilisierungselement miteinander verriegelbar ausgebildet sind bzw. miteinander verriegelt sind.

One aspect of the invention relates to a USB port for mounting on a printed circuit board, comprising:

• - a USB socket mounted on the circuit board; and
• - A stabilizing element mounted on the circuit board, wherein the stabilizing element surrounds the USB socket at least in sections, and wherein the USB socket and the stabilizing element are formed lockable with each other or are locked together.

The USB socket can be for example one with the USB 2.0 . 3.0 or 3.1 be a compatible USB port and / or as a port type USB Type A , USB Type B or USB Type-C. The USB socket can have connecting elements on a side facing in a mounting state of the printed circuit board, with which the USB socket is fastened to a connection region of the printed circuit board. Likewise, the stabilization element on a side facing in the mounting state of the printed circuit board side have connecting elements with which the stabilizing element is attached to the connection region of the printed circuit board. For this purpose, the connecting elements of the stabilizing element can be made larger than the connecting elements of the USB socket. As a result, the connection between the stabilizing element and the printed circuit board can be made more resilient, so that tensile loads which are absorbed by the stabilizing element do not lead to damage to the connection between the stabilizing element and the printed circuit board.

The stabilizing element surrounds the USB socket at least in sections along a connecting direction. The connection direction is the direction in which a USB plug complementary to the USB socket is inserted for connection to the USB socket. In the assembled state, the stabilizing element can enclose the USB socket over a length of preferably 10 mm to 20 mm and particularly preferably 16.5 mm in the direction of the connecting direction. Alternatively, the stabilizer element may surround the USB socket along the entire length of the USB socket along the connection direction.

• - einen Befestigungsabschnitt zur Montage des Stabilisierungselements an der Leiterplatte; und
• - einen Stabilisierungsabschnitt, welcher die USB-Buchse zumindest abschnittsweise umschließt.

Preferably, the stabilizing element further comprises:

• - A mounting portion for mounting the stabilizing element on the circuit board; and
• - A stabilization section, which encloses the USB socket, at least in sections.

In particular, the attachment portion comprises the connection elements of the stabilization element. In the mounted state of the USB connection, it is provided that the fastening section is arranged opposite the connection region of the printed circuit board. In other words, the attachment portion is mounted in the terminal area of the circuit board. In contrast, the stabilization section may at least partially project beyond the printed circuit board in the mounted state of the USB connection. Preferably, the stabilizing portion in the assembled state can project beyond the printed circuit board completely against the connecting direction.

In particular, the stabilizing section may have a guide opening which is designed to receive the USB socket. For this purpose, the USB socket can be inserted or counter to the direction of connection into the stabilizing section or into the guide opening. The stabilizing portion may be configured such that the stabilizing portion encloses the USB socket for a length of at least 3 mm along the connecting direction. In this case, the stabilizing section or the guide opening may be in contact with the USB socket, or the stabilizing section or the guide opening is spaced from the USB socket.

Such a configuration of the material thickness makes it possible to achieve an advantageous weight distribution of the stabilizing element or to perform an optimal determination of the center of gravity of the stabilizing element. For example, it is possible to make the attachment portion harder than the stabilization portion so as to shift the center of gravity of the stabilization member toward the attachment portion. On the one hand, a simpler mounting of the USB connection on the printed circuit board can be achieved since the shifted center of gravity towards the fastening section or the higher weight of the fastening section holds the USB connection on the intended connection region of the printed circuit board. Furthermore, the stability of the USB port can be increased overall.

Preferably, the stabilizing element may be designed to be electrically conductive, wherein the USB socket and the stabilizing element have an electrical contact closure with each other. This makes it possible for a shield running on the outside of the USB socket to be connected in an electrically conductive manner to the stabilizing element. Thus, the stabilizing element can additionally act as a shield. For example, the stabilizing element can be made of zinc and manufactured by die casting. Alternatively, the stabilizing element may be formed as an electrical insulator, for example, the stabilizing element may be made of plastic.

The USB socket has at least one locking element, which can be locked or locked with at least one complementary recess of the stabilizing element. In particular, the at least one locking element may be formed on one side of the USB socket, which, in the assembled state of the USB connector on the printed circuit board, faces away from the printed circuit board. The one locking element may further be resilient. Preferably, the USB beech may comprise two locking elements, in which case the stabilizing element has two complementary recesses. In particular, the at least one locking element or the two locking element and the at least one complementary recess or the two complementary Aussparrungen are designed such that the USB socket and the stabilizing element in the mounted state engage with each other or are locked together.

Preferably, the USB socket has a stop, which can engage in a complementary recess of the stabilizing element. Thus, it is possible that the USB port with the stabilizing element mounted in State of the USB port is locked. That is, the USB socket can not be moved relative to the stabilizing element in the mounted state of the USB port. In particular, the stop and the indentation can each be arranged on the USB socket or the stabilizing element in the direction of the connecting direction.
