RU2447538C1 - Delay-line structure of spiral type - Google Patents

Abstract

FIELD: electricity.

SUBSTANCE: delay-line structure of spiral type contains metal frame with at least one spiral located at ends of dielectric supports. At least one metal ring with grooves with rigidly fixed free ends of dielectric supports is installed at frame concentrically in regard to spiral; the ring has possibility of translational movement along the system axis. At the ring there is also a tool for ring translation in the form of protrusion with threaded hole for connection with pin which ends are installed at grooves of housing flanges. In result of pins rotation metal rings are translated with spirals along longitudinal axis of delay-line structure. During spirals movement distance between them is changed and it leads to changes in operating frequency and delay coefficient of the structure. It allows adjustment of delay-line structure.

EFFECT: provision of structure adjustment.

Description

The invention relates to electronic equipment and can be used in delay systems.

Known retarding system of a spiral type with anomalous dispersion (patent RU 2067335, authors Kuzmina F.P., Orlova S.M., H01J 23/24, published 09/27/96, BI No. 27), containing a spiral, mounted in a metal case with dielectric supports.

In this slowdown system, which is closest to the proposed one, the disadvantage is the inability to configure the slowdown system.

The problem to which the invention is directed is to create a custom slow-down system.

The technical result of the invention consists in the possibility of changing the parameters of the retarding system.

This technical result is achieved by the fact that in a retardation system of a spiral type containing a metal casing, inside of which dielectric supports are installed and at least one spiral secured with one end of the dielectric supports, it is new that coaxial to the casing is additionally introduced, at least at least one metal ring with grooves in which the other ends of the dielectric supports are mounted and rigidly fixed, while each metal ring is mounted with the possibility of longitudinal movement about in relative body further inputted via the means for moving the ring.

The means for moving the ring can be made in the form of a protrusion on the ring, in the protrusion there is a threaded hole for detachable connection with a stud, the ends of which are installed in the flanges of the housing.

Using the specified means for moving located on the ring, the metal rings are moved with spirals connected by means of dielectric supports along the longitudinal axis of the retarding system. When moving the spirals, the distance between them changes, which leads to a change in the operating frequency and the deceleration coefficient of the system. This makes the slowdown system customizable.

Figure 1 presents an example implementation of the design of the proposed retarding system of a spiral type.

The retardation system of the spiral type comprises a metal housing 1, three spirals 2, dielectric bearings 3, three metal rings 4, studs 5, flanges 6 and 7 of the housing of the retardation system.

Inside the metal casing 1, spirals 2 and dielectric supports 3 are installed. Coaxial to the casing 1 are metal rings 4 with grooves. The spirals 2 are fixed with one end of the dielectric supports 3. The other ends of the dielectric supports 3 are mounted and rigidly fixed in the grooves of the metal rings 4. On the cylindrical surface of each ring 4 there is a protrusion with a threaded hole, the axis of which is parallel to the longitudinal axis of the retarding system. Studs 5 are inserted into the threaded holes of the rings, the ends of which are installed in the grooves of the flanges 6 and 7 of the housing of the retarding system. Moreover, each ring is connected by a threaded connection to one of the studs.

The setting of the retarding system of the spiral type is as follows.

The studs 5 are detachably connected to the threaded holes of the rings 4. Due to the rotation of the studs 5, the metal rings 4 with spirals 2 move along the longitudinal axis of the retardation system. When moving the spirals, the distance between them changes, which leads to a change in the operating frequency and the deceleration coefficient of the system.

A prototype was made, which confirmed the operability of the claimed device. Housing parts were made of 12Kh18N10T steel, spirals were made of MOB vacuum melting copper, dielectric holders were made of VK-94 ceramics.
