The "normal state" referred to in the present invention refers to a state in which a current can be normally conducted. For example, when the conductive sheet overheating and power-off structure is applied to a socket or plug, the so-called "normal state" does not include that the electric power when the socket or plug is used exceeds the load, the contact between the socket and the plug is poor, and the socket Or the cross-sectional area of the plug that allows the current to pass is too small, there is a foreign matter between the socket and the contact surface of the plug, and other abnormal use of the socket or plug.

Please refer to the first figure and the second figure, which disclose the overheating and power-off structure of the conductive sheet according to the first embodiment of the present invention, including: a first conductive sheet (1), a second conductive sheet (2), and an overheating damage member (3), of which: The first conductive sheet (1) is provided with a first groove (11), and the second conductive sheet (2) is provided with a second groove (21) corresponding to the first groove (11). 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 that is open 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 is accumulated, but the elastic force can also be provided by an external elastic element, and the implementation is not limited. In addition, the direction of the acting 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.

In this embodiment, 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 a curved 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) may be integrally formed from a conductive material (for example, metal).

The support member (34) is disposed between the first limiting piece (31) and the second limiting piece (32). Normally, the first limiting piece (31) and the second limiting piece (32) can be restricted. The similar movements between the first restricting portion (312) and / or the second restricting portion (322) can force the second conductive piece (2) to contact the first conductive piece (1). In detail, the first limiting piece (31), the second limiting piece (32), and the connecting portion (33) may jointly define an accommodating space (30). The shape of the support member (34) in this embodiment The example corresponds to the receiving space (30) to fit in the receiving space (30). Here, the supporting member (34) has a pair of engaging portions (341) for engaging the first limiting piece (31) and the second limiting piece (32) to better fix the supporting member ( 34) to prevent the support (34) from coming off. The pair of engaging portions (341), the first limiting piece (31), and the second limiting piece (32) may have a concave-convex or convex-concave fitting type, and are not limited in implementation. In addition, the shape of the above-mentioned support member (34) does not necessarily correspond to the accommodation space (30), that is, whether the shape of the support member (34) fills the accommodation space (30) is not critical, as long as the support member (34) The position 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, The desired effect is achieved, so the shape of the support (34) can also be a block, a cylinder, an elliptical cylinder, an irregular block, etc.

The support member (34) can be damaged at a destruction temperature. The material of the support member (34) can be an insulating material such as plastic (including thermosetting plastic or thermoplastic plastic), or a non-insulating material such as metal or alloy. It is a low melting point alloy. Therefore, the damage of the support member may include any of the following conditions: softening, melting, liquefaction, gasification, deformation, cracking, pyrolysis, and coking.

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).

Continue to refer to the fourth and fifth figures, when the first conductive sheet (1) and the second conductive sheet (2) heat up due to abnormal conditions of current or voltage in the circuit to be protected, the first conductive sheet (1) and the heat of the second conductive sheet (2) are conducted to the support (34). When the support member (34) receives an overheating temperature exceeding the working temperature, for example, when the working temperature rises to about 130 ° C or 140 ° C, the support member (34) will be damaged by heat (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 the first restricting portion (312) or / and the second restricting portion (322) toward the groove (S), so that the restricted distance (T2 ') is smaller than or equal to the groove width ( S1), and it is no longer enough 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 through The forces are spread apart relative to each other to form a disconnection.

Please refer to FIGS. 3 and 5 again. In other words, under normal conditions, the overheating damage member (3) has an initial dimension in the Y direction, and the initial dimension can be maintained by a support member (34). Take advantage of this overheating The initial size of the destruction member (3) forces the second conductive sheet (2) to contact the first conductive sheet (1) in the X direction to form a path (such as a live line path or a neutral line path). At this time, the first conductive The working temperature of the sheet (1) or / and the second conductive sheet (2) will be transmitted to the overheating damage piece (3); when the overheating damage piece (3) receives an overheating temperature exceeding the working temperature, the effect The force forces the overheating damage piece (3) to change size in the Y direction to form an overheating size. For example, the support piece (34) is destroyed at the overheating temperature, and conditions for forming the overheating size are provided. The overheating size cannot force the The second conductive sheet (2) contacts the first conductive sheet (1), and keeps the second conductive sheet (2) away from the first conductive sheet (1) to form a disconnection (for example, interrupting the live wire path or the neutral line) path). Preferably, after the second conductive sheet (2) is far from the first conductive sheet (1), the first conductive sheet (1) can support the overheating destruction member (3), so that the overheating destruction member (3) ) Will not be scattered randomly.
