Description

The claimed relay relates to electrical engineering and can be used in industrial automation circuits.

A time relay [1] is known, consisting of an insulating casing, inside of which there is a control circuit and an output electromagnetic relay, clamps for connecting external conductors, a knob for adjusting the time delay setting. The disadvantages of this relay are its large overall dimensions, due to the location on the front panel of the setting scale with a large number of divisions. The use of the relay in question is economically feasible only in cases where it is necessary to accurately set the setpoint.

It is also known a time relay [2], taken as a prototype, the design of which is shown in figure 1, consisting of an insulating base (socket) 10 with sockets 11 and clamps 12 for connecting external conductors, an electromagnetic relay 1 with hard leads 3 on its base 2, a semiconductor time prefix 4 with hard leads 13 on the base 6, containing a plastic case with a printed circuit board with circuit elements located on it and a setpoint regulator 5. The relay of the design in question differs in small dimensions, which, along with other factors, due to the absence of numbered scale. Due to the small size, such relays are widely used, and especially in those cases when high requirements are not imposed on the accuracy of setting the time settings.

The disadvantages of this timer are limited functionality, because its use is possible only for mounting external conductors in the plug-in method using screw clamps 12 located on the base of the relay 10, and the complexity of its design. The design under consideration can provide the functions of a time relay only when the electromagnetic relay and the time set-up are installed together on the base (socket), since the mutual electrical connection of the electromagnetic relay and the time set-top box is carried out only through their hard leads and special elements located in the base 10 (socket). In this case, when using an intermediate relay without a time prefix, one type of socket is used, and when using an intermediate relay with a time prefix, a socket of a more complex design uses special elements between the electromagnetic relay and the time prefix.

The technical result of the proposed technical solution is the expansion of functionality and simplification of the design of the time relay.

The specified technical result is achieved by the fact that in the time relay, consisting of an electromagnetic relay with terminals located in the base, a semiconductor time set-top box with a base and a setpoint regulator, a protrusion is mechanically conjugated to the base of the electromagnetic relay on the basis of the semiconductor time set-top box, and on the side opposite to the base protrusion semiconductor time prefix made element mounting the time relay.

The essence of the claimed technical solution lies in the fact that due to the claimed design, a universal time relay is created, with the electromagnetic relay and the semiconductor device connected to each other with a protrusion on the basis of the semiconductor device and the electrical installation between them, which allows you to use this time relay as for connecting external conductors by soldering to the terminals of the electromagnetic relay, and plug-in method using a standard outlet used in the computer ekte with electromechanical relays.

Figure 2 shows a General view of the inventive time relay, figure 3 is the basis, where the following notation:

1 - electromagnetic relay;

2 - the base of the electromagnetic relay 1;

3 - conclusions for external mounting of the electromagnetic relay 1;

4 - semiconductor time prefix;

5 - setpoint regulator;

6 - the base of the semiconductor time prefix 4;

7 - protrusion on the basis of 6;

8 - relay mounting element;

9 - conductors of the electrical connection between the electromagnetic relay 1 and the time prefix 4.

The time relay consists of an electromagnetic relay 1 with terminals 3 at the base 2 and a semiconductor time attachment 4 with a base 6 and a setpoint regulator 5 fixed to each other by a protrusion 7 at the base 6. The necessary electrical connection between the electromagnetic relay 1 and the time attachment 4 is made directly by conductors 9. The fastening element of the relay 8 is made in the form of a plate with holes that provide mechanical fastening of the time relay, which are located on the base 6 on the opposite side of the protrusion 7. Thus

Thus, the claimed relay, in contrast to the prototype, represents a complete design without installing it on a common base (socket).

The work of the proposed time relay is similar to the work of the prototype. When you turn on the supply voltage to the two terminals of the electromagnetic relay, the time prefix receives power through the conductors of the electrical connection and the time delay starts. After some time, the time prefix gives a signal to turn on the electromagnetic relay. Thus, the electromagnetic relay operates with a time delay determined by the position of the settings regulator of the semiconductor time prefix.

The proposed time relay can be included in the electrical circuit by mounting by soldering the external conductors to the terminals 3 of the electromagnetic relay, or by the plug-in method when installing it on a standard electromagnetic relay socket having terminals with screw terminals. Thus, the proposed design allows you to perform a time relay for connecting external conductors by soldering or plug-in method. In the latter case, a standard socket from an electromagnetic relay can be used, which eliminates the need for additional costs for the manufacture of a special socket for installing an electromagnetic relay with a time prefix.

On the basis of the claimed technical solution, a universal time switch for industrial production has been developed.
