The present invention relates to an improved explosion proof connector for electrical circuits. high voltage and high titre currents is particularly suitable

JiS is not too difficult, explosion-proof connectors or · Connections with controlled arcing for low amperages and low voltages create »But the development of connections for circuits of 200 amps and 480 volts, for example, brings an acute Problem with "because the resulting arc under these circumstances is comparable to a welding arc Size and temperature. Under these circumstances, I am maintained for a correspondingly long period of time Arc would be devastating because no construction materials known from would naIts.

D _e r terminal according to the present Jirfindunk comprises a multi-contact Anordnun ^; for use in a high voltage and high current line and is particularly designed to handle the closing and breaking of. Contacts between the Steckerkonfcaktueilen and the socket contact parts to reduce arc duration occurring to a minimum. The present invention relates to a plug-in device which can be "coupled and uncoupled" quickly and which has a spring-assisted release or locking device (detent means) in order to bring about a quick connection and disengagement of the connection elements.

The aim of the invention is to create an explosion-proof Connection especially for hone jtroms and high Voltages is suitable and has means for reducing the arc time between the contacts.

Another object of the invention is to provide a A clutch that can be engaged and disengaged quickly and in which the contacts pass through the arc phase at a rate which reduces the adverse effects of the arc limited to the contacts and the insulation

51, while the anterior lipid of the spring J?

While the spring 51 is discharged or relaxed, the solder part 11 continues into the plug part 1? Moved up to a position as can be seen from Fig. '$ of the drawing, v / o the plug contact parts 'dj> in egg: e plug socket conraict parts 17 engage. Through this process it is advertised that "the contacts no raiucli are guided through the arc phase, 4a,; the effect of the arc; on the contacts and the insulation is reduced to a minimum. Jiupulun _: 7shülHe 52 leads to an inwardly engaging position between the plug parts 2, 5 and the socket contact parts 17, in which the spring washer 45 is located on the other side of the second stop surface 46. In this position, a sealing ring 62 carried by the plug housing 11 engages in a sealing manner at the end of the Socket housing 1- and is pressed together between these housings in order to create an effective seal between these parts.

Disengagement of the electrical contact elements is achieved by rotating the coupling sleeve 52 in the opposite direction, As a result, the spring washer 43 is pressed against the second soleplate
