Description

The previous cartridge is intended to make it difficult to unscrew the incandescent lamp from the black, and also to disconnect it from the electrical circuit without using a special switch, by applying screws to the screws connected to the incandescent, central contact and provided with an insulating part of the contact ring.

In FIG. 1 depicts an axial section of the proposed cartridge; FIG. 2 - view of the central contact and contact cylinder.

The cartridge consists of a casing 1 with 4: (a sleeve 2 directed onto it, in which is placed the spiral spring 3, pressing the isolation disk 4 downwards with the central contact 8 and equipped with an insulating part 11, with a contact ring 7 (Fig. 2). Electric current leads to the clamps b and b fixed in the disk 4 and through the contact 8 and the ring 7 passes into the screws 13 and 13 connected to the filament of the lamp and fastening the insulating disk 5 located under the contact 8 and the ring 7, 12 chuck with curved edges on one side and with slot 14 at the bottom ti.

A sleeve 15 is screwed onto the external thread 16 of the casing 1, separated from the casing 1 by an insulating part 17..

The casing 1 and the sleeve 15 are provided with 12 holes 19, which are at the same height with the slot 14 of the sleeve, and the sleeve 2 with the same hole, but slightly offset in the vertical direction relative to the latter.

To screw into the lamp cartridge, the sleeve 2 must be pulled down and, having aligned the screwdriver on it with the holes 19, pass a pin through them that prevents the lamp holder 12 from rotating when the lamp is screwed into it. When the lamp is screwed in, this pin is removed and the lamp rotates, together with the rotation of the holder 12 so that the lamp will not be unscrewed, but will only be disconnected from the current circuit when the screw 13 is in contact with the insulating part 11 of the ring 7 .

In order to remove the cartridge from the cartridge, it is necessary to pass the pin through the holes 19, which can be done either by breaking the lamp bulb or by tugging the solenoid 2 and aligning its hole with the holes 19.

The subject of the patent.

A cartridge for electric lamps, characterized by the use of a centrally located centrally contact 8 and equipped with an embedded insulating part 11-11, contact ring 7, which contact 8 and ring 7, are clamped to the heads of screws 13 electrically connected to the thread, and 13 bearing inner race 12th oliruschey disk 5.
