The invention relates to separable, electrical plug connections in which a sleeve on the one arranged rotatably by two connecting bodies and releasably connected to the other connecting body and a device with an explosive charge for separating the two bodies at one Ignition of the charge is provided.

There are known electrical connectors in which the explosive charge in an annular Recess is arranged, which is provided on one of the plug parts and through the edge of a annular member is closed, which with the other connecting part by a releasable Connection connected and in the recess by angularly spaced pins in the Working position is held, which are broken when the charge is ignited.

With these connectors it is a reassembly of the connector parts after a Igniting the charge and separating the annular member from the other plug part is necessary, one to arrange new explosive charge in the annular recess, the edge of the annular member in To insert the recess, new connecting pins in the aligned holes of the annular Link and the one connector part to be arranged and then the tubular member in turn to connect with the other connector part.

The purpose of the present invention is to provide a separable electrical connector to provide the type described above, in which the plug parts easily and quickly after disconnection can be reassembled by igniting the explosive charge. To this end the sleeve, which is rotatably arranged on one body, has a bayonet connection in a known manner with the second body, so that both bodies by rotation of the sleeve with respect to the one connecting body can be connected or disconnected and the explosive charge when detonated Sleeve rotates in the connector release direction with respect to the one connecting body.

The connector according to the invention consists in that the sleeve with the other body over a bayonet connection is in connection, so that the connection or separation of both bodies in on known way by rotating the sleeve in or out of the engagement position of the bayonet lock takes place and the explosive charge between a support of the connecting part and one with the Sleeve connected and arranged around the plug connection axis rotatable thrust bearing to the Separable, electrical plug connection

act to put the two connector parts 10 and 11 in. As shown in FIG. 2 is an all-

Working engagement with each other and pulling them into common annular housing 39 on shell 21

attached directly to the rear of the disc 31. The housing 39 has, seen in the radial direction, an inner axial wall 40, an outer one axial wall 44 and a rear wall 45. The outer wall 44 extends forward to the point of contact with the rear surface of the disc 31. The inner wall 40 does not extend quite as far as the wall 44 at the front, the front edge of the wall 40 being supported against a rearwardly directed sleeve 43, which is rotatable with respect to the disk 31. In this embodiment, the sleeve 30 and washer 31 prevented from moving backwards along the jacket 21 so that when the sleeve 30 is in the triggering direction is rotated, the plug part 10 is forcibly pushed away from the part 11. Through a Longitudinal wedge 41 on the housing, which cooperates with a slot 42 in the jacket 21, is the housing 39 is prevented from rotating relative to the jacket 21.

A rotation of the sleeve 30 and the disc 31 in the triggering direction is made possible by a rotatable Driving a stop member 60 causes which is attached to the disc 31 and within the housing 44 is arranged. The rear surface of the disc 31 is at 46 over part of its angular extent except, this recess ends at a steep, axially lying shoulder 47, the serves as a stop for the link 60. The support 60 becomes counterclockwise to that of FIG. 2 position shown, with an expandable drill cartridge 49 in a bore 50 in an elongated Extension 54 of the housing 39 is housed. The cartridge 49, with a front expandable Bellows end 51 is held in place by a removable break block 52 which is inserted into the Part 54 is screwed in at 55. The outer end of the fracture block 52 is with part one at 56 designated electrical connector, for example a connector with two contact pins provided, which when energized by a power source will cause the cartridge to explode and a Part 51 of which can expand in the axial direction.

Within the curved channel 57 in the housing 39 is a movable one composed of a first drive member 59 formed support is arranged, which is attached to the sleeve 43, also the already mentioned Stop member 60, a rod 61 connecting the two members 59 and 60 and one between the helical compression spring 62 provided on both members 59 and 60. When cartridge 49 detonates and the front portion 51 thereof expands, the connected support member becomes clockwise of the in F i g. 2 pushed away, so that the disc 31 is rotated so that that the connector parts separate from each other. The rod 61 slidably disposed in the link 60 is, and the spring 62 cushions the drive of the disk and thereby prevent the parts from breaking. As a result of the drive of the link 60, the disc 31 and the sleeve 30 rotate in the plug release direction. This allows the pins 29 to move out of their respective seats at the end of the grooves 37 trigger and by a further rotation of the disk by the drive member 60 presses the sleeve 30 the plug part 10 away from the part 11, thereby providing a smooth and instantaneous separation of the two Connector parts is ensured.
