Las figuras 5 y 6 representan las partes superior e inferior del circuito impreso de la placa.Figures 5 and 6 represent the parts upper and lower of the printed circuit board.
Las figuras 1-6 representan un termostato bimetálico de acuerdo con el presente invento. El termostato bimetálico comprende una caja exterior 1 dispuesta en un extremo de una parte 2 que tiene una rosca macho 21 para acoplamiento con equipo externo.Figures 1-6 represent a bimetallic thermostat according to the present invention. He bimetallic thermostat comprises an outer box 1 arranged in a end of a part 2 having a male thread 21 for coupling with external equipment.
La parte 2 está preferiblemente hecha de latón y tiene una cavidad central roscada internamente 22 adaptada para recibir un elemento de termostato sensible 3. El elemento sensible 3 comprende un bulbo que está provisto de un extremo roscado 31 para permitir una conexión de acoplamiento por coincidencia con la cavidad 22 de la parte 2 y que contiene dos láminas de coeficientes de dilatación térmica diferentes (por ejemplo, de acero y de aluminio), dispuestas rígidamente la una sobre la otra, fijadas por un lado al bulbo y libres de moverse por el otro lado; los contactos eléctricos o patillas 23 están fijados a los extremos de las mismas. Al aumentar la temperatura, el metal más sensible tiende a dilatarse pero, al estar frenado por el otro metal, el cual es más resistente a los cambios de temperatura, se curva, conmutando así el contacto eléctrico.Part 2 is preferably made of brass and it has an internally threaded central cavity 22 adapted to receive a sensitive thermostat element 3. The sensitive element 3 it comprises a bulb that is provided with a threaded end 31 for allow a coupling connection by coincidence with the cavity 22 of part 2 and containing two sheets of coefficients of different thermal expansion (for example, of steel and aluminum), rigidly arranged on top of each other, fixed by one side to the bulb and free to move on the other side; the contacts electrical or pins 23 are fixed to the ends of the same. As the temperature rises, the most sensitive metal tends to expand but, being braked by the other metal, which is more resistant to temperature changes, it curves, thus commuting The electrical contact
Dentro de la caja 1 hay una placa con un circuito impreso 10, por ejemplo una placa de "vetronite" (fibra de vidrio), la cual soporta un relé de potencia 4. La placa, que puede verse mejor en las figuras 5 y 6, comprende un circuito impreso 100, que está integrado en la placa 10 y que está adaptado para conectar eléctricamente el elemento sensible 3 al relé de potencia 4, así como medios para fijar el relé de potencia 4 en dicha placa 10. La placa 10 comprende dos orificios rebordeados metálicos 55 ara conexión con las patillas metálicas 23 del elemento sensible 3; más concretamente, las patillas 23 del elemento sensible 3 están soldadas en los orificios 5 de la placa 10. El relé de potencia está normalmente soldado a la placa 10 por medio de patillas dispuestas sobre orificios rebordeados metálicos 11 de la placa 10. El relé de potencia está adaptado para trabajar con voltajes normales y altos niveles de corriente, es decir, con voltajes de 12 ó 24 voltios, y corrientes del orden de decenas de amperios; por ejemplo, el relé 4 es capaz de trabajar con valores de 12 V y 35 A durante 10 minutos, ó de 12 V y de 25 A durante 60 minutos.Inside box 1 there is a plate with a printed circuit 10, for example a "vetronite" board (fiberglass), which supports a power relay 4. The board, which can be seen better in figures 5 and 6, it comprises a circuit printed 100, which is integrated in plate 10 and which is adapted to electrically connect the sensitive element 3 to the relay power 4, as well as means for setting power relay 4 on said plate 10. Plate 10 comprises two flanged holes metal 55 for connection with the metal pins 23 of the element sensitive 3; more specifically, the pins 23 of the element Sensitive 3 are welded in holes 5 of plate 10. The Power relay is normally soldered to plate 10 by means of pins arranged on metal flanged holes 11 of plate 10. The power relay is adapted to work with normal voltages and high current levels, that is, with 12 or 24 volt voltages, and currents of the order of tens of amps; for example, relay 4 is able to work with values 12 V and 35 A for 10 minutes, or 12 V and 25 A for 60 minutes minutes
Conectados a la placa 10 hay dos cables
eléctricos 701, 702, de los cuales el cable 701 se usa para
suministrar potencia al termostato (normalmente a 12 V ó 24 V), y
el cable 702 se usa para dar salida a la señal que se origina en el
relé de potencia 4 y utilizable por el equipo externo. Como puede
verse mejor en las figuras 5 y 6, el circuito impreso 100 de la
placa 10 tiene orificios rebordeados metálicos 71, 72 para conexión
de los conductores eléctricos del cable de potencia 701, y
orificios rebordeados metálicos 73, 74, para conexión con los
conductores eléctricos del cable de salida 702; el circuito impreso
100 comprende tiras metálicas 75 que enlazan los orificios 5 con
los orificios 11, y
otras tiras metálicas 75 para la
conexión del relé al cable 702 y de dicho relé 4 y el elemento
sensible 3 al cable 701.Connected to the plate 10 are two electrical wires 701, 702, of which the cable 701 is used to supply power to the thermostat (usually at 12 V or 24 V), and the cable 702 is used to output the signal that is originates in power relay 4 and can be used by external equipment. As can be best seen in Figures 5 and 6, the printed circuit 100 of the plate 10 has metal flanged holes 71, 72 for connection of the electrical conductors of the power cable 701, and metallic flanged holes 73, 74, for connection with the electrical conductors of the output cable 702; the printed circuit 100 comprises metal strips 75 that link the holes 5 with the holes 11, and
other metal strips 75 for the connection of the relay to the cable 702 and of said relay 4 and the sensitive element 3 to the cable 701.
La placa 10 sirve para evitar interferencias entre las patillas 23 del elemento sensible 3, el circuito eléctrico para el suministro de potencia, y el circuito eléctrico para la señal de salida emitida por el relé de potencia 4, situación que podría dar lugar a un cortocircuito del relé o, en todo caso, a impedir que el propio relé 4 funcione correctamente, con el resultado de que serían entregadas señales de salida incorrectas por medio del cable eléctrico de salida de señales 702.Plate 10 serves to avoid interference between the pins 23 of the sensitive element 3, the circuit electrical for power supply, and electrical circuit for the output signal emitted by power relay 4, situation that could lead to a short circuit of the relay or, in In any case, to prevent relay 4 itself from functioning correctly, with the result that output signals would be delivered incorrect by means of the electrical signal output cable 702
Esta solución permite un fácil montaje del termostato. Dentro de la caja 1 se aplica una resina aislante 6, por ejemplo, una resina de epoxi, para proteger al relé de potencia contra las altas temperaturas, preferiblemente de hasta 260º.This solution allows easy assembly of the thermostat. Inside the box 1 an insulating resin 6 is applied, for example, an epoxy resin, to protect the power relay against high temperatures, preferably up to 260 °.
La reducción de los tiempos de fabricación, combinada con la simplicidad del dispositivo, justifica una reducción sustancial de los costes.The reduction of manufacturing times, combined with the simplicity of the device, justifies a substantial reduction of costs.
El termostato es del tipo TCR, es decir, que además de percibir la temperatura, al alcanzar un valor determinado, hace que se conmute un contacto eléctrico y que se produzca la consiguiente apertura o cierre de un contacto eléctrico. Este tipo de termostato se usa para mantener la temperatura dentro de los límites fijados, o en equipos neumáticos e hidráulicos, por ejemplo, en los intercambiadores de calor la señal de salida controla automáticamente la refrigeración por fluido o los sistemas de calefacción.The thermostat is of the TCR type, that is, besides perceiving the temperature, when reaching a value determined, it causes an electrical contact to switch and produce the consequent opening or closing of a contact electric. This type of thermostat is used to maintain the temperature within the set limits, or in pneumatic equipment and hydraulic, for example, in heat exchangers the output signal automatically controls cooling by fluid or heating systems.
La figura 4 ilustra el circuito del termostato antes descrito, en donde 71 y 72 son los terminales de potencia, y 73, 74 son los terminales de salida en el modo de contactos normalmente cerrados, es decir, cuando el relé 4 está en estado de activado, lo que a su vez es función del elemento sensible 3.Figure 4 illustrates the thermostat circuit described above, where 71 and 72 are the power terminals, and 73, 74 are the output terminals in contact mode normally closed, that is, when relay 4 is in the state of activated, which in turn is a function of the sensitive element 3.
