Description

Protective component and insulated conductive heating module thereof

This creation is related to circuit protection components, and mainly provides a protection element that is relatively simple and reliable in structure, contributes to the development toward thinning, and an insulated conductive heating module associated therewith.

In general, electrical equipment is inevitably damaged by short-circuit damage, or a large current such as a lightning surge, or an abnormality in the output voltage of the battery unit, etc., or damage some important components or valuable components in the circuit, even burning the circuit to cause a fire. .

In order to prevent damage to precision electronic equipment caused by instantaneous excess current or excessive voltage, electrical components are usually added to the circuit. The protection components are mainly provided with heat generated by an excessively large current. The molten fusible conductor, when the instantaneous current exceeds a predetermined value, the fusible conductor is melted by the heat generated by the instantaneous excessive current to form an open circuit, so that the excessive current does not flow into the circuit, the protection circuit and the electrical appliance Free of damage.

In order to prevent the heat generated by the excessively large current from being absorbed by the electrodes of the protective element and causing the melting timing of the fusible conductor to be delayed, a protective element for rapidly melting the fusible conductor through the heating element appears as shown in Fig. 1; Similar to the protective element provided with the heating element 15, an insulating substrate 16 is disposed in an outer frame 18, and first and second electrodes 11, 12 are disposed on the insulating substrate 16, and a surface of the insulating substrate 16 is disposed on the surface of the insulating substrate 16. a plurality of heating elements 15, a heating element extraction electrode 13 electrically connected to the side ends of the heating elements 15, and a fusible conductor 14 supported by the heating element extraction electrode 13, and the soluble conductor 14 constitutes the first 1. The second electrodes 11, 12 are in communication.

Similar to the protective element provided with the heating element 15, the first electrode 11 and the second electrode 12 are connected to an external circuit, and the current path from the first electrode 11 to the second electrode 12 via the fusible conductor 14 is formed by the fusible conductor 14. At the same time, the heating element extraction electrode 13 constitutes a power supply path of the heating elements 15.

Basically, when the fusible conductor 14 flows over a rated overcurrent, the fusible conductor 14 is melted by its own heat generation, so that the external circuit can be blocked. Further, the heat generating bodies 15 are heated by electric current, and the heat generated by avoiding an excessively large current is absorbed by the first and second electrodes 11 and 12 of the protective element, thereby causing the meltable conductor 14 to be melted and delayed.

However, the conventional protective element is provided by encapsulating the heat generating bodies 15 on the surface of the insulating substrate 16 through an insulating member 17, and then providing heat generating electrical connection with the side ends of the heat generating bodies 15 above the insulating member 17. The body lead electrode 13 not only has an extremely complicated overall structure, but is not conducive to the development toward the thinning direction, and the heat source of the heat generating body 15 cannot be directly conducted to the fusible conductor 14, and the protective function must be started by a relatively high current. It may be that the heating element 15 fails to achieve the desired protective function prior to the failure of the fusible conductor 14.
