Description

For the adventure of an electric pump used to illuminate the sights of artillery systems, use cartridges of various designs. The diversity of these constructions leads to an increase in the cost of shafts and to the complication of repair and replacement of parts that have failed, (moreover, the cartridges used on the bench are structurally incoherent and unreliable in operation.

The proposed universal paron, at the suggestion of the author, rebuilds all the tasks that stand in the way of rationalizing the lighting of the mechanics: the special scales of the artillery systems, and provides the possibility of using it with any type of attachment and electroplate, making it universal.

The essence of the invention lies in the fact that the central contact is fixed on the lead wire inserted into the paron and is held by an insulating sleeve abutting the collar on the internal surface of the cartridge and behind the plug which is screwed into the latter.

The foregoing is illustrated in a drawing.

which shows a longitudinal section of the proposed cartridge (. having a single-pole version).

In case Y, there is an electrical insulating sleeve 2 of central contact 3, into which 4 current-carrying wires live. A rubber washer about and a metal washer 6 are installed behind the sleeve, forming a seal. The pulling in of the washers 5 and b is carried out by a stopper 7, which is fitted with a straight knurling along the surface 5 of the flange and screwed into the tail part of the housing 1. When tightening, the sleeve 2 abuts against the flange 9 inside the housing / cartridge. The cavity 10 for accommodating the lamp base is provided with a screw thread.

In the single-pole version, the second wire is the metallic material part of the artillery system (“earth”). In the case of a bipolar design, a tail contact was placed electrically connected to the housing / in the tail part of the housing / is isolated from the contact 3 and the core 4; the core wire is soldered

to an additional contact washer. Wire strands are recommended to be connected to the metal parts of the cartridge by soldering, which is the most reliable method of fastening.

Subject invention

A cartridge for electric incandescent lamps, in particular for illuminating the sights of the sights, characterized in that the central contact is fixed on the lead wire introduced into the soda and held by an insulating sleeve abutting the collar on the inner surface of the cartridge and tightening the screw into the latter.
