LANCE FOR HOLDING A SENSOR OR SAMPLER FOR METAL MELTS

The lance comprises an upper part (1) and a lower part (2), which are arranged on a sensor or sampler and are detachably connected with one another by a plug-in connector, and a blocking device (5) movably arranged at the upper part of the lance by a gravitational force. The plug-in connector has tw...

Zusammenfassung:	The lance comprises an upper part (1) and a lower part (2), which are arranged on a sensor or sampler and are detachably connected with one another by a plug-in connector, and a blocking device (5) movably arranged at the upper part of the lance by a gravitational force. The plug-in connector has two coupling parts (3, 4) plugged into one another in the longitudinal direction of the lance. A first coupling part is arranged at the upper part and the second coupling part is arranged at the lower part. One of the coupling parts at its open connecting end has an opening or groove (9). The lance comprises an upper part (1) and a lower part (2), which are arranged on a sensor or sampler and are detachably connected with one another by a plug-in connector, and a blocking device (5) movably arranged at the upper part of the lance by a gravitational force. The plug-in connector has two coupling parts (3, 4) plugged into one another in the longitudinal direction of the lance. A first coupling part is arranged at the upper part and the second coupling part is arranged at the lower part. One of the coupling parts at its open connecting end has an opening or groove (9) extending itself from the front side of the coupling parts in the longitudinal direction of the lance. The opening or the groove has an extension spatially formed from the front side of the first coupling part in a circumferential direction of the coupling part. An elevation is formed at the second coupling part and intervenes into the extension. A latching element of the blocking device is partially arranged between a part of the elevation and a part of its opening or groove extending itself in the longitudinal direction of the lance. The blocking device is movable in the longitudinal direction of the lance. The coupling parts are formed as bayonet lock, and as hollow cylinder within the circular cross-section. The second coupling part arranged at the lower part is plugged into the first coupling part arranged at the upper part. An electrical coupling is arranged in the plug-in connector.
