Abstract

The invention relates to a device which causes a safety locking of the electrical contactor of faulty ventilator thermocontacts or the like. The device is placed in the thermocontact element. It comprises a stationary contact (5), a movable contact (6), a safety return spring (11), and one or more pins or weld seams (12) made of a eutectic alloy and meltable at a predetermined temperature. When the temperature rises above a predetermined abnormal level, the meltable pins (12) change from a solid state to a liquid state, and the tensioned safety return spring brings the movable contact (6), which moves freely on slides, back against the contactor (4), thereby creating a link between connectors (8 and 9). This link immediately triggers the operation of the disengageable ventilator or the like.

Description

La présente invention conerne un dispositif de sécurité fusible sur contacteur électrique des thermocontacts ou analogues. The present invention relates to a fuse safety device on an electrical contactor of thermal switches or the like.

Les thermocontacts actuellement utilisés dans l'industrie présentent un inconvénient majeur. The thermal switches currently used in industry have a major drawback.

En cas de défaillance de l'élément thermosensible 2, fig. 1, le thermocontact est inefficace, du au non enclenchement du contacteur électrique 4 resté en position de rupture de circuit entre les bornes 8 et 9 fig. 1 et empêche la mise en service du ventilateur ou analogue. In case of failure of the heat-sensitive element 2, fig. 1, the thermal switch is ineffective, due to the non-engagement of the electrical contactor 4 which remains in the circuit break position between the terminals 8 and 9 fig. 1 and prevents the commissioning of the fan or the like.

Il en résulte une augmentation de température excessive. Cette surchauffe entratne une détérioration prématurée des organes moteur et des organes du circuit réfrigérant. This results in an excessive temperature increase. This overheating leads to premature deterioration of the engine parts and the parts of the refrigerant circuit.

Le dispositif selon l'inventeur permet de remédier à cet inconvénient du à la défaillance d'organes thermocontacts de tous types, et permet d'éviter toutes les conséquences qui en découlent
Ce dispositif est inséré à même l'élément thermocontact et se décompose comme suit, fig. 1
- une enclume fixe 5
- une enclume mobile 6
- d'un ressort de rappeL de sécurité 11
- de goupille(s) ou soudure(s) de sécurité fusible 12
à température prédéterminée en alliage eutectique ternaire ou binaire.The device according to the inventor makes it possible to remedy this drawback due to the failure of thermo-contact members of all types, and makes it possible to avoid all the consequences which ensue therefrom.
This device is inserted directly on the thermal contact element and is broken down as follows, fig. 1
- a fixed anvil 5
- a mobile anvil 6
- a safety recoil spring 11
- fuse safety pin (s) or weld (s) 12
at predetermined temperature in ternary or binary eutectic alloy.

Fonctionnement normal du thermocontact fig. 1
Lors de température normale prédéterminée par la sonde thermosensible 2, sertie sur le corps de thermocontact 1 la tige de poussée 3, poussée par la sonde thermosensible 2 vient actionner le contacteur électrique 4 qui vient en butée contre l'enclume mobile 6, permettant ainsi la jonction des bornes 8 et 9 noyées dans le bouchon 7.La jonction des bornes 8 et 9 provoque la mise en service du ventilateur ou analogue. En cas de défaillance de l'élément thermosensible 2, la poussée de la tige 3 est insuffisante, et le contacteur électrique 4 ne peut Aetre actionné, et le venti- lateur est hors fonction. Normal operation of the thermal switch fig. 1
At normal temperature predetermined by the thermosensitive probe 2, crimped on the thermoswitch body 1 the push rod 3, pushed by the thermosensitive probe 2 actuates the electrical contactor 4 which abuts against the movable anvil 6, thus allowing the junction of terminals 8 and 9 embedded in the plug 7. The junction of terminals 8 and 9 causes the fan or the like to be put into service. In the event of failure of the heat-sensitive element 2, the thrust of the rod 3 is insufficient, and the electrical contactor 4 cannot be actuated, and the fan is off.

La température augmente-dans tout le circuit de refroidissement. Lorsque cette surchauffe anormale atteint une température prédéterminée, la goupille(s) ou soudure(s) de sécurité 12 passe de l'état solide à l'état liquide et libère l'enclume mobile 6 et l'enclume fixe 5 sur ses glissières. Le ressort de rappel de sécurité 11, de part sa traction, rappelle l'enclume mobile 6 et celle-ci vient se mettre en butée sur le contactueur 4 et mermet la jonction des bornes 8 et 9. Le ventilateur débrayable est mis en service, évitant ainsi une surchauffe et protège le moteur ou analogue ainsi que le circuit réfrigérant de détérioration prématurée.  The temperature increases throughout the cooling circuit. When this abnormal overheating reaches a predetermined temperature, the safety pin (s) or weld (s) 12 changes from the solid state to the liquid state and releases the movable anvil 6 and the fixed anvil 5 on its slides. The safety return spring 11, due to its traction, recalls the movable anvil 6 and the latter comes to abut on the contactor 4 and allows the junction of the terminals 8 and 9. The disengageable fan is put into service, thus avoiding overheating and protects the engine or the like as well as the refrigerant circuit from premature deterioration.
