Electro-optical plug and socket and electro-optical connector

The present invention relates to an electro-optical connector and to an electro-optical connector connectable to the electro-optical connector.

The present invention therefore also relates to an electro-optical

Plug connection of an electro-optical plug with an electro-optical socket.

Electro-optical connectors or general hybrid connectors are known in the art. A known in the prior art problem of particular optical

 Connectors is to transmit the optical signals from the connector side to the female side or generally to connectors.

In this case, it is necessary to optimally couple the light from a light exit surface of one of the connector pairs to an entry surface of the corresponding connector pair. This results in both constructive and tolerance-related problems in the transmission of optical signals. In general, in addition sender and receiver are used, so that the known in the market conventional connectors represent only connecting elements between transmitter and receiver.

In other words, transmitters and receivers are often distributed in devices and the prior art connectors provide a line connection between the transmitting and receiving stations. In the context of increasing miniaturization of devices and mobile applications, it becomes necessary to transmit and receive devices and transmission media and to arrange optical conductors as possible within a connector. This ensures that, for example, on the plug and / or socket side of a connector, a transceiver or receiver or transmitter can be accommodated.

Here are several difficulties to overcome. For one, it is difficult for space transceiver, transmitter and receiver within the miniaturized

Accommodate connectors and on the other hand, the problems in the optical and mechanical coupling of optical signals from the plug to the socket side and vice versa while housing transmit, - or receive

Transceiver devices.

Object of the present invention is therefore to provide an electro-optical connector and an electro-optical jack, overcome the aforementioned disadvantages and are easy to manufacture and are safe to handle.

In describing the invention, reference is made to the entire disclosure content of DE 10 2010 044 834.6, DE 10 2010 044 835.4 and DE 10 2010 044 836.2.

The electro-optical connector according to the invention which is designed for transmitting electrical and optical signals comprises a connector housing in which a contact carrier is arranged, which has a plurality of electrical contacts, wherein the contact carrier has mechanical coupling means for receiving optical conductors and further comprises an optical coupling portion to Coupling or decoupling of optical signals in or out of the optical conductors.

Ie. the electro-optical connector has a plurality of receiving devices for introducing optical conductors, which is formed by means of an optical coupling portion which is formed by the contact carrier, optical signals in this or can decouple.

According to the invention, the contact carrier is at least in the region of the optical

Coupling section on a transparency for optical signals. Ie. the contact carrier is either preferably completely made of transparent material for optical signals or at least transparent in the area in which the optical conductors run with their filament.

The mechanical coupling means are formed in a preferred embodiment as grooves, preferably as V-shaped grooves or V-grooves in the contact carrier;

ideally, the grooves are parallel, so that in multi-pole electro-optical

Plugs the optical conductors are parallel to each other.

The optical coupling section of the contact carrier has optical coupling means for coupling or uncoupling optical signals in and / or out of the end faces of the optical conductors. The optical coupling section as a whole constitutes the region of the contact carrier through which the optical signals coming or transmitted from or to the optical conductors can pass and exit the contact carrier again from an exit surface on the underside of the contact carrier. The idea according to the invention consists, inter alia, of determining the optical paths by reflection at optical interfaces as intended from the entrance surface, thus from the optical coupling means to a light exit surface or generally

To guide exit surface in the contact carrier and to reflect there. Consequently, the optical coupling portion having an optical interface having the refractive index n is formed adjacent to the optical coupling means. The

In this case, the interface is offset with respect to the optical paths from and to the end faces of the optical conductors sent or received optical signals. In other words, according to the invention, two factors have to be considered.

On the one hand, a transparent material having such a refractive index n is to be used, so that the optical interface acts as a total reflection surface and, on the other hand, the interface is to be arranged on the contact carrier, with respect to orientation and position, such that the optical paths are intended to form an exit surface on the underside of the substrate Contact carrier to be steered. Advantageously, the optical interface is defined as a curved,

in particular concave outer surface formed. The refractive index n is chosen such that the transition at the interface from the interior of the contact carrier and indeed from the transparent, but optically denser coupling section to the ambient air acts as a conical total reef reflection mirror.

Therefore meets an optical signal, which from the optical fiber into the optical

Coupling reaches, on the interface, which acts as a total reflection surface, so at this interface, the light is not outwardly out of the contact carrier, but reflected at this purpose and intended in the direction of

Exit surface at the bottom of the contact carrier. The curved, in particular conical or convex-conical interface is thus oriented with respect to the mechanical coupling means so that optical signals emanating from the optical conductors are reflected to the contact carrier underside.

Another special feature is that in a specially designed

Embodiment, the electrical contacts, the mechanical coupling means thus cover the longitudinal openings of the grooves and thus fulfill two functions. On the one hand, they serve as mechanical protection and cover for the optical conductors and on the other hand, they represent electrical contacts. Through this construction, one obtains a particularly compact, small-sized

electro-optical connector.

The electro-optical jack according to the invention also comprises a contact carrier with an optically transparent optical coupling section with a light entry surface for leaking or to be received optical signals to or from the connector, which can be connected to the electro-optical jack.

The electro-optical socket according to the invention comprises an electro-optical component, preferably an optoelectronic transceiver or an electro-optical transmitting or electro-optical receiving device, such. As a VCSEL or a photodiode. Further advantages, objects and details of the invention will become apparent from the description of the embodiments with reference to the drawings; in the drawings shows:

Coupling means 14a for the optical signals from the optical conductors. The optical coupling means 14a are formed as an optical interface 15.

In an advantageous manner, the optical interface 15 is conical

Total reflection surface formed. This means that, viewed from the outside, a convex elevation is arranged in the region of the optical coupling means 14a. From the optically denser medium (inside the transparent contact carrier 13), which has a higher refractive index n than the ambient air, the interface 15 acts as a conical total reflection mirror for incident optical signals.

Side of the contact carrier 13 are side walls 18, which surround the respective outer optical fibers 2.

Consequently, the mating connector has corresponding corresponding mechanical coupling means 38, as shown in Fig. 8. In the embodiment according to FIG. 8, the mechanical coupling means are designed as semi-cylindrical elevations.

In FIG. 6, the grooves 16a which are open according to FIG. 5 are covered with contact elements 20.

The contact elements 20 comprise a first contact portion 21 and a second contact portion bent therefrom. Thus, there is a bend 23 between the first and second contact portions 21, 22.
