Description

The invention relates to the field of radio engineering and can be used for the manufacture of the Y-joint in the form of a system of interwoven flat conductors in the manufacture of circulators on the concentrated elements of the meter and decimeter wavelength ranges with a high level of operating power.

A known method of manufacturing a Y-joint in the form of a system of interwoven conductors, interwoven and isolated between each other (US patent No. 6646608, MKI: H01Q 1/38 from 11.11.2003). The disadvantage of this method is the need for a number of complex and lengthy technological operations. In addition, the flat conductors of the Y-joint formed using photosensitive electrically conductive paste have a small thickness, which reduces the level of operating power of decoupling devices with this joint.

There is also known a method of manufacturing a Y-joint in the form of a system of interwoven conductors interlaced and insulated between each other (US patent No. 5611878, MKI: H01P 1/383, H01P 11/00, H01P 1/387 of 03/18/1997) used in the manufacture of circulators on lumped elements. The method is based on the formation of a Y-joint due to injection of a conductive paste under pressure into the channels formed in the ferrite elements. The disadvantages of this method is the use of complex technologies.

Closest to the claimed technical solution according to the technical essence and the technical result achieved is a method of manufacturing a Y-joint in the form of a system of interwoven and insulated flat conductors from each other (US patent No. 7095291 B1, MKI: H01P 1/383 from 08/22/2006) . The known method is based on sequential folding due to bending around the ferrite element of flat conductors made of thin foil, in accordance with a randomly selected direction (clockwise or counterclockwise) on a polygonal (hexagonal) ferrite element. The described method is adopted as a prototype of the invention. The disadvantages of this method of forming the Y-joint are the lack of symmetry of the Y-joint due to the different relative positions of the flat conductors relative to each other and, as a result, the low operating frequencies of the circulators (less than 1 GHz), the high complexity of the process of weaving the conductors, the need to use polygonal ferrite element (hexagonal) for the correct orientation of the conductors and a low level of working power of the joint (50 W), caused by the need to use as a ma terial conductors of thin foil.

The technical result of the invention is to provide a method of manufacturing a Y-joint in the form of a system of interwoven flat conductors for circulators on lumped elements, providing symmetry of the Y-joint, when two flat conductors of each arm are parallel to each other at the required distance from each other and at the required angular distance relative to the conductors in the other shoulders and each conductor intersects with four others, while passing over two alone and under two other of Four silent, as well as reducing the complexity of manufacturing and achieve high repeatability of manufacturing Y-junction independence of the shape of the ferrite element and the possibility of using conductors of a flat cable, allowing better operation power decoupling device.

The technical result is achieved by the fact that the method of manufacturing a Y-joint in the form of a system of interwoven flat conductors for circulators on lumped elements comprises the steps of mechanically installing flat conductors of equal length parallel to each other on the side surface of an imaginary cylinder with fixing their ends on the circles of the first and second bases of the imaginary cylinder , with their subsequent interweaving by rotation of the bases of an imaginary cylinder relative to each other around the axis of an imaginary qi Indra on calculated angle (less than 180 °), while the approximation. When placing flat conductors on the lateral surface of an imaginary cylinder, the end of each of the conductors to be fixed on a common circle rotates around the longitudinal axis of the conductor by 180 ° in the direction opposite to the subsequent direction of rotation of the bases.

In FIG. 1 shows the initial placement of flat conductors on the side surface of an imaginary cylinder.

In FIG. 2 shows the steps for manufacturing a Y-joint in the form of a system of interwoven conductors.

In FIG. 3 shows a system of interwoven conductors.

The essence of the invention lies in the fact that the method is based on the formation of a Y-joint by interlacing flat conductors pre-placed parallel to each other on the side surface of an imaginary cylinder and twisted around its longitudinal axis by 180 ° with fixing their ends on the circles of the first and second bases of the imaginary cylinder (Fig. 1) due to rotation of the bases of an imaginary cylinder, which are simultaneously approaching, at an angle of not more than 180 °. When the bases of the imaginary cylinder are rotated, the mutual position of all flat conductors is simultaneously changed, while the conductors are intertwined and brought together, as a result of which they occupy a position when the conductors are arranged in pairs parallel to each other at the required distance from each other and at the required angular distance relative to the others and each conductor intersects with four others, while passing over two alone and under two other of these four. The resulting structure is planarized and fixed.

An example embodiment of the invention is modeled and presented in FIG. 2. For clarity, the process of forming the Y-joint is divided into several stages, each of which corresponds to its own angle of rotation of the bases of the imaginary cylinder relative to each other. Initially, six flat conductors are distributed over the surface of an imaginary cylinder (Fig. 1), formed by the circles of the first and second bases of the imaginary cylinder. Each flat conductor is twisted around its longitudinal axis by 180 ° in the direction opposite to the direction of rotation of the base of the imaginary cylinder. With the mutual rotation of the bases of an imaginary cylinder, flat conductors twisted in the opposite direction are straightened with simultaneous approach. The final form of the formed Y-joint is a system of interwoven conductors, in which two flat conductors of each arm are parallel to each other at the required distance from each other and at the required angular distance relative to the conductors in the other arms and each conductor intersects with four others, while passing over two alone and under two other of the four, shown in FIG. 3. The final distance between the flat conductors (size A, Fig. 3) is determined by the angle of mutual rotation of the bases of the imaginary cylinder. In the given example, the bases of the imaginary cylinder at the end of the formation of the Y-joint are rotated relative to each other by 160 °.

When implementing the proposed method, various options for fastening flat conductors to the bases, for example, fastening with clamps, soldered or adhesive joints, can be used.

The application of the proposed method provides the manufacture of the Y-joint in the form of a system of interwoven flat conductors for circulators on lumped elements with high repeatability and low laboriousness, and also allows the use of multicore flat conductors consisting of double-insulated wires as conductors, which extends the technological capabilities of the manufacturing method Y-joints, while increasing productivity and reducing the complexity of adjusting the circulators.
