The sheet (2) has a force away from the first conductive sheet (1). For example, the second conductive sheet (2) is preset with an open position relative to the first conductive sheet (1), so when the first groove (11) and the second groove (21) overlap A groove (S) can be formed together, and an elastic force can be accumulated, but the elastic force can also be provided by an external elastic element, which is not limited in implementation. In addition, the direction of the force can be defined as an X direction, and the extending direction of the first conductive sheet (1) can be defined as a Y direction.

The overheating damage component (3) includes a first limiting piece (31), a second limiting piece (32), a connecting portion (33) and a supporting member (34):

In this embodiment, the first limiting piece (31) has a first free end (311), and the first limiting piece (31) has a first free end (311). The free end (311) is provided with a first restricting portion (312), the second restricting piece (32) has a second free end (321), and the second free end (321) is provided with a second restricting portion (322) The first restricting portion (312) or/and the second restricting portion (322) may be an arc surface. The connecting portion (33) connects the first limiting piece (31) and the second limiting piece (32). In this embodiment, the first limiting piece (31), the second limiting piece (32) and the The connecting portion (33) can be integrally formed of conductive material (for example, metal).

The supporting member (34) is arranged between the first limiting piece (31) and the second limiting piece (32), and can limit the difference between the first limiting piece (31) and the second limiting piece (32) under normal conditions. The close movement between the first restricting portion (312) or/and the second restricting portion (322) can force the second conductive sheet (2) to contact the first conductive sheet (1). In detail, the first limiting piece (31), the second limiting piece (32) and the connecting portion (33) can jointly define an accommodation space (30). The shape of the support (34) is in this embodiment The example corresponds to the accommodating space (30) to fit into the accommodating space (30). Here, the supporting member (34) has a pair of engaging portions (341) for engaging with the first limiting piece (31) and the second limiting piece (32) to better fix the supporting member ( 34), to prevent the support (34) from detaching. The pair of engaging portions (341), the first limiting piece (31), and the second limiting piece (32) can be in a concave-convex or convex-concave mating pattern, which is not limited in implementation. In addition, the shape of the aforementioned support (34) does not necessarily correspond to the accommodating space (30), that is, whether the shape of the support (34) fills the accommodating space (30) is not critical, as long as the support (34) ) The location between the first limiting piece (31) and the second limiting piece (32) can restrict the close movement between the first limiting piece (31) and the second limiting piece (32), that is, it can To achieve the expected effect, the shape of the support (34) can also be a block, a cylinder, an elliptical cylinder, an irregular block, etc.

The support (34) can be destroyed at a failure temperature. The support (34) can be made of insulating materials such as plastics (including thermosetting plastics or thermoplastics), or metal or alloys of non-insulating materials. It is a low melting point alloy.

Please continue to refer to the third figure, the groove (S) has a groove width (S1), and the distance between the first limiting piece (31) and the second limiting piece (32) under normal conditions is defined as an initial distance ( T1), the initial distance (T1) is less than or equal to the groove width (S1), and the maximum distance between the first restricting portion (312) and the second restricting portion (322) under normal conditions is defined as a limited distance (T2), the defined distance (T2) is greater than the groove width (S1). The maximum pitch of the connecting portion (33) in the direction of the initial pitch (T1) is defined as a positioning pitch (T3), and the positioning pitch (T3) is greater than the groove width (S1).

Please continue to refer to the fourth and fifth diagrams. When the desired protection circuit has abnormal current or voltage conditions, causing the first conductive sheet (1) and the second conductive sheet (2) to heat up, the first conductive sheet (1) and the heat of the second conductive sheet (2) will be conducted to the support (34). When the support (34) receives an overheating temperature that exceeds the operating temperature, it will be destroyed. For example, when the operating temperature rises to about 130°C or 140°C, the support (34) will be thermally damaged (including softening and melting). , Liquefaction, gasification, deformation, cracking, pyrolysis, coking, etc.), at this time, the force of the second conductive sheet (2) will force the first limiting sheet (31) and the second limiting sheet (32) ) Move similarly to displace the first restricting portion (312) or/and the second restricting portion (322) toward the groove (S), so that the defined distance (T2') is less than or equal to the groove width ( S1), and is no longer sufficient to force the first conductive sheet (1) and the second conductive sheet (2) to contact each other, thereby allowing the first conductive sheet (1) and the second conductive sheet (2) to pass The forces spread out relative to each other to form an open circuit.

Please refer to the third and fifth figures again. In other words, under normal conditions, the overheating destruction member (3) has an initial size in the Y direction, and the initial size can be maintained by a supporting member (34). Using the initial size of the overheating destruction member (3) to force the second conductive sheet (2) to contact the first conductive sheet (1) along the X direction to form a path (such as a live path or a neutral path), and then the The working temperature of the first conductive sheet (1) or/and the second conductive sheet (2) will be transferred to the overheating destruction part (3); when the overheating destruction part (3) receives an overheating temperature exceeding the working temperature , The force forces the overheating destruction member (3) to change its size in the Y direction to form an overheating dimension. For example, the support member (34) is destroyed at the overheating temperature to meet the conditions for forming the overheating dimension. The second conductive sheet (2) cannot be forced to contact the first conductive sheet (1), and the second conductive sheet (2) is moved away from the first conductive sheet (1) to form an open circuit (such as interrupting the live wire path or the Neutral path). Preferably, after the second conductive sheet (2) is far away from the first conductive sheet (1), the first conductive sheet (1) can support the overheating destruction element (3) so that the overheating destruction element (3) ) Shall not be scattered randomly.

Please continue to refer to the sixth figure, which is the second embodiment of the present invention. The shape of the overheat breaking element is roughly the same as the first embodiment. The overheat breaking element (3A) also includes a first limiting piece (31A) and a second The limiting piece (32A), a connecting portion (33A) and a supporting member (34A), the first limiting piece (31A), the second limiting piece (32A) and the connecting portion (33A) also define an accommodation space ( 30A), the difference from the first embodiment is that the first limiting piece (31A), the second limiting piece (32A) and the connecting portion (33A) are not integrally formed, and the supporting member (34A) is not The corresponding accommodation space (30A) is only used to support the first limiting piece (31A) and the second limiting piece (32A). The overheating destruction member (3A) can force the first conductive sheet (1A) and the second conductive sheet (2A) to contact each other under normal conditions, and can be destroyed by the support member (34A) at the overheating temperature.
