DE7606572U1 - FLASH THERMAL ADAPTER - Google Patents

Description

Patent-Treuhand-Gesellschaft for electric light bulbs mbH, Munich

♦) Flash adapter

The innovation relates to a flash adapter with rotating mount at one end to accommodate a flash cube fitted with flash lamps that can be ignited by high voltage pulses, as well as in the Slotted mount of a flat camera, matching sheet socket at the other end. The turning solution has four 90 turning positions when turned 360 Occupying rotary cylinder with a square recess and an axially extending, cross-slotted, co-rotating cylinder in this Double cone, which interacts with a square socket pin with a central cylinder bore of the lightning cube. Electrical contacts the rotary mount are connected in an electrically conductive manner to electrical conductor tracks of the blade base.

Compensation of electrostatically built-up charges via the ignition system (external power supply lines, detonator) can lead to the accidental ignition of flash lamps that are ignited with a high voltage pulse. Becomes a seated in the aforementioned adapter rotating socket Touched the flash cube to continue rotating it after taking a picture this danger for the still to be led into the flashing position, unused flashbulbs of the cube.

According to the innovation, accidental ignition is still in the flashing position This prevents the flashing lamps of a flashing cube inserted into this adapter rotating socket from being touched, that means are provided which short-circuit the outwardly led Stromzule ungen these flash lamps.

'As a means of shortcuts1, for example, a jointed,

Figure 1 shows such a contact ring in plan view. Figure 2 shows such a contact plate in plan view.

Figure la shows the contact ring "wound up" in a side view of Figure 1.

2a shows the contact plate in a side view according to Figure 2.

Figure 3 shows a flash cube adapter with in its rotating socket inserted contact ring in section.

FIG. 4 shows the flash cube adapter according to FIG. 3 with a contact ring in the threatening version in plan view.

The contact ring 1 (Figure l) is for example made of copper, brass, etc. Its outer diameter is about 21 mm, while its inner diameter runs to about 15 mm be. The same applies to the contact plate 2 (FIG. 2). Ring 1 and plate 2 are divided by joints or support sections 4 into curved contact sections 5 and 6, which are somewhat resilient to compensate for the height. The ring or plate lie in the annular space Ja of the rotary mount 7 of the flash cube adapter 8

End of the lightning cube adapter 8, the other end of which is a leaf base 12 is executed. The electrical conductor tracks 13 of the base 12 are connected to electrical contacts l4 of the socket 7 through Power supply lines 15 connected. Is a lightning cube in socket 7 used, they are not in the ignition position above the contacts standing flash lamps through contact with sections 5 and 6 electrically short-circuited by ring 1 or plate 2. This short circuit is eliminated when the lamps are in the ignition position come.

Instead of the described ground contacts, suitably trained, the lamps short-circuiting side contacts can be provided in or on the rotary socket.
