SU97602A1 - Non-reactive Plug Resistance Store - Google Patents

Description

The subject of the invention is a non-reactive plug-in resistance box for alternating low and sound frequency currents, consisting of low-impedance-wound low-resistance (less than 100 ohms) and more complex large-value impedances, contact plug-ins for decades of resistance, a two-pin clip for separate output About g plug devices of low-resistance decades and a double electric screen inside which all parts of the store are mounted.

The design of the proposed plug-in store provides a reduction in its residual inductance. This is achieved by the fact that plug-in devices of low-resistance decades and a separate lead from them to the bifilar clamp are made bifilar. In order to ensure the continuity of shielding, all 1pins are equipped with two transverse contact bridges, which, when inserting the plugs into the slots of the 1plate devices, block the apertures in the screens.

FIG. 1, depicting the layout of the magazine, is designated: / - low-resistance decade plug-in devices connected by a bifillary output 2 with a bifillary clamp 5; 4 - plug devices of high resistance decades; 5 - ordinary clips.

FIG. Figure 2 shows the construction of a separate low-impedance plug device made bifillary. As can be seen from the drawing, the current /, the passage to the row of plug contacts 6, 7, 8 W. 9, returns over the plate 10, insulated with a gasket 11 from all contacts except 6.

FIG. 3 shows a plug 12 provided with transverse contact bridges 13 and M, due to which when inserting the plugs into the slots of the plug device / through holes 15 in the inner 16 and outer 17 walls of the screen 18 are blocked.

Subject invention
