DE2359195A1 - Combined fluid and electrical connector - has contact pins and sockets encircling concentric fluid channels with sealing ring - Google Patents

Abstract

The combined fluid-coupling and electrical connector has its centre region occupied by the fluid coupling, and the electrical contact pins and sockets form a circle around it. One half of the connector contains the contact sockets and the other half the contact pins. The fluid coupling has a central fluid channel in one connector half and located at the centre of a taper. The entrance to this channel is widened to accept a sealing ring. The outer circular fluid channel passes out next to the centre channel. The second half of the fluid coupling has a circular trench with another sealing ring to mate with the outside of the taper.

They each consist of a central coupling tube that is rigidly or movably attached to a central buffer coupling of the rail vehicle, while the ends are connected to the pipeline to be coupled. The electrical contact elements are located on lines, trier claws, which are arranged diametrically to one another on the coupling heads projecting above the end face of the coupling tubes and about 90 of the outer surface.

include about 90 of the outer surface area of the coupling head ";

The centering claws cause the coupling parts to be centered precisely and thus secure their exact coupling in a prescribed angular position.

Since the application of fluidic auxiliary energy now also on has found its way into the field of missile technology, there is a need to use such combination couplings as connecting means, e.g. between the payload tip and the To use the fuselage of a missile. The division of plug bodies into such assemblies results in at the mechanical separation points also separation points for the electrical, hydraulic and pneumatic lines. These line connections must be designed to be fast, absolutely trouble-free and functionally reliable, because of them the function of the respective missile depends. A further complicating factor is that such plug-in connections take up little space may claim and must be extremely light. Furthermore, from tactical requirements, for example, a warhead with a cutting effect in different angular positions with the missile fuselage connect another difficulty. Such warheads must depending on whether, for example, a bridge when flying over or under or a sea vehicle when passing its longitudinal

side is to be destroyed, in different angular positions, based on a normal situation, even by inexperienced personnel, be connectable to the missile fuselage.

The invention is therefore based on the object of a combined plug connection with several fluidic and to create electrical line connections that and is designed to save weight in such a way that neither electrical lines nor hoses during the coupling process jammed or damaged that no line or. Tubeless is required for the coupling process and that a coupling option in different angular positions is possible with the least possible construction effort.

Starting from a plug connection for connecting electrical and fluid lines by means of a plug ker— and a socket part, the fluidic one in the middle and have the electrical connecting elements concentric thereto, this object is achieved according to the invention by additional fluidic lines, the socket side in concentric, sealing rings having annular channels and on the plug side in a circular cross-section Line pins open out, and that the electrical plug connections on the socket side as concentric, arranged Ring contacts are formed.

With the help of such a combined plug connection can be a warhead as a result of the concentric to the central line arranged annular spaces and ring contacts in a simple manner in any angular position with the missile fuselage connect quickly and securely. The angular position can still be changed even if the warhead is already connected to the missile fuselage. Here is

BO 9-8 23/0094

only a loosening of the mechanical locking elements is necessary to keep the warhead in relation to the To be able to twist missile fuselage. After setting the new angular position, the mechanical interlock is restore.

According to a simplified embodiment of the invention are the electrical connection elements designed as plug contacts in groups in fixed angular positions (e.g. 90 each) arranged to each other.

It is true that in this embodiment the possible angular positions between the warhead and the missile are carried out the number of groups of plug contacts is limited, but the design of the electrical plug connection is limited easier. Such an embodiment must therefore always be used when only two preferred angles - lay between the parts to be connected, e.g. between a warhead and a missile fuselage are needed.

According to a further feature of the invention, the sealing rings are on the inner circumferential surface of the annular spaces of the fluid. Dischen line connections arranged.

According to another embodiment of the invention are the sealing rings on both sides of the annular spaces of the fluidic plug connection on the end face of the socket part arranged.

In this embodiment there is the further advantage that the plug part of the fluidic plug connection is designed according to the invention so that the fluidic Lines open out at the front of the plug part.
