Abstract

The invention relates to elements of electrical equipment, in particular, resistors, and can be used in various automation and communication systems. The purpose of the invention is to increase the manufacturability of manufacturing a resistor by reducing the requirements for the accuracy of the geometric dimensions that constitute its components. The resistor consists of a ceramic frame 1 with a central mounting hole 2 and a resistor winding wound on this frame. Two terminals 4 are led to one of the ends of the frame 1. In addition to the central hole 2 and parallel to it in frame 1, through holes 3 are made, in which similar wire terminals 4 are placed, forming a wedge-shaped slot 5 at one end of the frame for embedding the onset of a resistive winding, and on the other - a baton hook 7. 2 ill.

Description

Phage.1

The invention relates to elements of electrical equipment, in particular resistors, and can be used in various automation and communication systems.

The purpose of the invention is to improve the manufacturability by reducing the requirements for the accuracy of the geometric dimensions of the component parts and changing the design of the terminals and their fastening element in the housing, which ensures the benefits in the through open holes 3 of the frame 1, are bent and formed by compression in the form of a hook 7 with reverse parties. This provides a mechanical fastening of the terminals and fixing them from longitudinal movement. Loop 6 serves to solder external mounting. When manufacturing a resistive winding 8, the beginning of the wire is pinched in a wedge-shaped slot 5 of one terminal, then produces a waste-free production technology with single-layer winding onto the frame 1, and two terminals with a release of 6 million pieces per year. At the same time, the end of the wire is soldered to the formers, saving 78 tons of brass and 0.5 tons of tin. FIG. 1 shows a common resistor

The terminals 4 are made of the same type and form a wedge-shaped slot 5 on one side and a loop 6 for 25 external mounting solders, and on the other hand a hook hook 7. On the frame 1 a single-layer resistive 8 winding is made of high-resistivity wire. To protect against external influences and impart a presentation, the resistor is covered on the outside with a layer of enamel (not shown). The dielectric frame 1 is made by extruding the ceramic material in the form of a tube through a die, which is then cut into blanks of the required length.
