Hinge (1) with an integrated electrical contact (2), wherein the hinge (1) consists of a hinge sleeve (4) which has on both ends plug-side openings (5, 15) and a plug-side opening (5) mechanically with a rotatable pin (3) is connectable, while the other plug-side opening (15) is formed for electrical contacting with a plug pin (11).

Description

The The invention relates to a hinge with an integrated electrical contact.

The Hinge is designed as a mechanical hinge and at the same time as a rotatable socket contact or rotary electrical Connector.

The The invention relates to a connector designed as mechanical rotary hinge and at the same time as a rotatable socket contact respectively rotatable electrical connector.

To a substantially cylindrical contact arrangement is provided, which are mechanically unilaterally with a rotatable hinge pin and on the opposite Connect side by means of an electrical contactor leaves.

It is possible, for example, a hinge sleeve one piece with the housing a mobile phone form or as an end-side Part of a mobile phone while the rotatable pins, for example, from a corresponding part from the lid of a mobile phone or a at one end part of a lid of a mobile phone can be formed. In this case, the lid, for example, a Screen or display that faces the second component a mobile phone, which has keyboard and control units features, rotates to move.

It would be desirable this rotatable joint, preferably in a mobile phone to one outwards open End to design so that, for example, an antenna connector can be connected to the mobile phone. In particular due to space and space problems and as a result of increasing miniaturization in mobile technology, as with many other electronic Devices, hardly suitable places to disposal stand, the problem arises to arrange this connector space-saving.

The Invention has given itself the task of a rotary hinge such to change, that over the hinge is an electrical connection can be produced.

According to the invention happens this by the features provided in claim 1.

preferred Embodiments emerge from the subclaims.

Further Advantages, objects and details of the invention are hereafter based on the representation of exemplary embodiments the invention described in the drawings.

Brief description of the drawings:

1 shows a schematic section through an electrical connector formed as a hinge;

2 shows a section according to the in 1 shown embodiment along the section line AA;

3 shows a schematic section, also according to the embodiment of the 1 along the section BB.

In 1 is a hinge 1 with an integrated contact 2 shown.

The hinge 1 is designed as a mechanical hinge and consists of a rotatable pin 3 and a corresponding operatively connected hinge sleeve 4 , The hinge sleeve 4 is formed for example of an electrically conductive tube material or even of a non-conductive plastic as a cylindrical sleeve. In the hinge sleeve 4 molded is near the plug-in opening 5 a circumferential locking groove 6 on the inner wall of the hinge sleeve 4 arranged. The hinge sleeve 4 with the circumferential locking groove 6 forms part of the hinge 1 , in which a rotatably mounted pin 3 can be introduced. The rotatable pin 3 preferably has at its plug-in end 7 one to the circumferential locking groove 6 corresponding locking ring arrangement 8th ,

The locking ring 8th runs so that a part of the rotatable pin 3 further than the position of the detent ring 8th in the hinge sleeve 4 protrudes, so that a secure bearing is provided on the cylindrical inner sleeve.

The locking ring 8th may in turn be formed as a circumferential spring ring, which in an unillustrated annular groove on the rotatable pin 3 is formed.

The spring ring can then when mounting the rotatable pin 3 in the hinge sleeve 4 so spring into the annular groove that an assembly of the rotatable pin 3 becomes possible. The spring ring then engages or dips into the annular groove and allows insertion into the plug-side opening 5 , whereby upon reaching the latching ring 8th at the position of the inner circumferential locking groove 6 the rotatable pin 3 operatively connected to the hinge sleeve 4 engaged. In this position, the pin 3 be rotated infinitely rotationally symmetric about its longitudinal axis.

Preferably, first and second contact zones 12 . 13 on the inside of the hinge sleeve 4 formed with the first and second contact zones of a pin 11 can work together.

The particular problem is that on the one hand the hinge 1 must be designed to be rotatable and thereby withstand mechanical stresses, on the other hand, however, an additional socket to be avoided.

In addition exists the problem is that the connected pin a good electrical connection with good mechanical Provide connection with the corresponding socket got to.

In one embodiment of the invention, the mechanical and electrical contacting by means of the first contact zones 12 and second contact zones 13 realized.

It is, as in 3 shown, the arrangement of the first contact zones 12 approximately at an angular distance of 60 ° symmetrically on the inner surface of the hinge sleeve 4 distributed. These first contact zones 12 For example, they may be formed as electrically supported hemispheres, which in turn are themselves connected to a conductor, not shown. In an embodiment not shown, the first contact zone 12 Also be designed as an electrically conductive ball bearing, which is rotatably arranged in a corresponding circumferential locking groove. The locking groove is in the 1 to 3 not shown.

The second contact zones 13 are formed as segments, which also at a symmetrical or asymmetrical distance along the inner surface of the hinge sleeve 4 spaced from the first contact zones 12 are arranged.

Preferably, the first contact zones 12 from the plug-in opening 15 spaced further inwardly than the second contact zones 13 , The first contact zones 12 and the second contact zones 13 together form a contact pair.

As in 2 clearly shown, the second contact zones 13 optionally be designed as segments or as not shown, as a completely encircling contact ring.

Corresponding to the first and second contact zones 12 . 13 is how in 1 shown the pin 11 formed, which at the plug-side end 16 or almost at a distance, via a contact groove 17 destroyed. At a distance there is a circumferential contact ring 18 passing through an insulator 19 from the pin 11 and thus of the contact groove 17 is electrically isolated. The contact ring 18 can with one in the center of the connector pin 11 located, rotatably mounted connection 20 be connected. By this configuration, the pin can be 11 rotate axially while the electrical connection 20 also mounted in the center, axially rotatable. When plugging in the pin 11 in the hinge sleeve 4 it comes to a contacting of the first contact zones 12 and second contact zones 13 with the contact groove 17 and the contact ring 18 , corresponding to the first contact zones 12 with the contact groove 17 connect electrically and the second contact zones 13 with the rotating contact ring 18 to be in electrical contact.

Due to the design of the first contact zones 12 In addition, there is a mechanical operative engagement with the contact groove 17 , so that in addition to the electrical connection also has a mechanically strong connection with the connector pin 11 is guaranteed. This will prevent the connector pin 11 unintentionally from its electrically contacted connection with the hinge sleeve 4 can be pulled out. The individual contact zones of the electrical contact 2 can be connected in a conventional manner with interconnects or with a flexible circuit board, so that a diverse application is possible.
