" Hand lamp made of molded insulation material.

The invention "relates to a hand lamp for ship, and port facilities. . "'

So far for. such systems hand lamps, their Main body made up of two separately manufactured parts, the wooden handle and the metal housing, were "used. On A metal threaded flange was screwed onto the housing, onto which the protective glass was secured by means of a glass retaining ring and the protective cage were attached. The flange could with the protective glass and the protective cage · also on normal Ship lights are screwed on.

In a further version of hand lamps there was a molded insulating handle with a housing-like tapering Lower part combined into one piece. In this version, the protective cage was attached to a threaded metal cap attached, which also at the same time the protective glass with the interposition of a seal against the hand lamp handle pressed.

The first-mentioned types of hand lamps had the disadvantage that the handle and the housing part are special easily loosened from each other if handled improperly, the cable slightly twisted bark moisture, penetrated into the terminal room. , ■

For hand lamps with one-piece insulated · ^und.Me-: tallgewindekappe but had special protective glasses and special protective cages are kept in stock. \

In the hand lamp according to the present invention the described EFaehteile are switched off, that the Isolierpreßstoffgriff with the housing, on which you can screw the normal threaded flange, in one piece is carried out and on the flange the normal Protective glass and protective baskets that also light up Can be used, attached. Since furthermore the lamp handle with the housing part, the flange and the glass holder ring on the new "hand lamp made of pressed insulating material are made off, the hand lamp also offers Usually advantages especially for ships. According to the invention is located in the housing space Hand lamp has an earthing bridge, which can be used for two and three-lobed versions can be used. This is of particular importance because if the current flow is disturbed, the incandescent lamp is usually unscrewed from the luminaire first. to look for the damage. Since almost exclusively sockets with metal housings are used for such Hand lamps are used and the cables are strong are stressed on train, the fault is very often on a loosened cable core, the end of the metal housing the socket "can have · In this state, however, the light bulb is unscrewed in damp locations dangerous if the hand lamp handle is also made of insulating material, because touching the / Socket housing occurs when the incandescent lamp is screwed out in the present case on the troubleshooting a tension about.
