Abstract

Embodiments disclose a device for interrupting current flow upon an electrical conductive sheet being overheated, for use in a plug or a power socket. The device includes a first electrical conductive sheet, a second electrical conductive sheet and a thermal circuit breaker. The thermal circuit breaker includes a limiting member and a supporting member. The limiting member and the supporting member are disposed over the first and second electrical conductive sheets transversely. The limiting member has a limiting portion. In a normal state, the limiting portion urges the second electrical conductive sheet to make contact with the first electrical conductive sheet to form a current passage and the second electrical conductive sheet thereby stores energy. The supporting member damages when receiving heat produced at a temperature greater than a working temperature, and the second electrical conductive sheet exerts an opposing force on the limiting portion to displace the limiting portion. In such a case, the first and second electrical conductive sheets withdraw from each other due to the opposing force, and the current flow is thereby interrupted.

For example, when the conductive sheet overheating and power-off structure is applied to a socket or a plug, the so-called "normal" does not include the overload of the electric power when the socket or plug is in use, the poor contact between the socket and the plug, and the socket Or the cross-sectional area of the plug that allows current to pass is too small, there are foreign objects between the contact surface of the socket and the plug, and other abnormal heating conditions caused by the abnormal use of the socket or plug.

Please refer to the first and second figures, 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 destruction component (3), wherein: 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 second conductive sheet (2) has a force away from the first conductive sheet (1). For example, the second conductive sheet (2) is preset with an open circuit 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 force can also be provided by the outside (such as a spring), and the implementation is not limited. In addition, the extending direction of the first conductive sheet (1) can be defined as an X direction, the second conductive sheet (2) is superimposed on the first conductive sheet (1) in a Y direction, and the Y direction is perpendicular to the X direction. .

The overheating destruction component (3) includes a limiting member (31) and a supporting member (32): the limiting member (31) and the supporting member (32) are adjacent to each other in the X direction, and the limiting member (31) And the supporting member (32) across the groove (S) along the Y direction, the limiting member (31) has a limiting portion (311), the limiting portion (311) includes a curved surface (3110), the The curved surface (3110) corresponds to the second conductive sheet (2). The limiting member (31) further includes a body portion (312) and a sleeve portion (313). The body portion (312) is connected to the sleeve portion (313) and the restricting portion (311). The body portion (312) ) Extends along the Y direction, and defines a fitting space (314) between the body portion (312) and the fitting portion (313) to accommodate the supporting member (32). In this embodiment, the fitting portion (313) includes a first extension section (3131) and a second extension section (3132). The first extension section (3131) extends along the X direction, and the second extension The section (3132) extends along the Y direction and is connected to the first extension section (3131). However, the implementation is not limited to this, for example, the second extension section (3132) may not be included, as long as it can be used to assist in positioning the support member (32). That is, the limiting member (31) and the supporting member (32) can have a coordinated positioning relationship to improve the convenience of assembly.

The supporting member (32) normally restricts the close movement of the limiting member (31). The shape of the support (32) corresponds to the nesting space (314) in this embodiment to fit into the nesting space (314). In addition, the shape of the supporting member (32) does not necessarily correspond to the fitting space (314), that is, whether the shape of the supporting member (32) fills the fitting space (314) is not critical, as long as the supporting member (32) It can restrict the similar movement of the limiting member (31) under normal conditions, that is, the expected effect can be achieved. Therefore, the shape of the supporting member (32) can also be a block, a cylinder, an elliptical cylinder, or an irregular block. Wait.

The support (32) can be destroyed at a failure temperature. The support (32) 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. Therefore, the failure mode of the support (32) may include any of the following conditions: softening, melting, liquefaction, gasification, deformation, cracking, pyrolysis, and coking.

Please continue to refer to the third figure, the groove (S) has a groove width (S1) in the X direction. The distance between the part of the limiting member (31) that crosses the groove (S) and the position of the support member (32) that crosses the groove (S) in the X direction in the normal state is defined as an initial distance ( T1), the initial distance (T1) is less than or equal to the groove width (S1). The maximum distance between the limiting portion (311) of the limiting member (31) and the supporting member (32) in the X direction in the normal state is defined as a limited distance (T2), and the limited distance (T2) is greater than the groove width ( S1). In this embodiment, the limiting member (31) further includes a blocking portion (315) corresponding to the first conductive sheet (1), and the blocking portion (315) and the supporting member (32) The maximum distance between them in the X direction 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, which causes 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 (32). When the support (32) receives an overheating temperature that exceeds the working temperature, it will be destroyed, for example, when the working temperature rises to about 130°C or 140°C At this time, the support (32) will be damaged by heat (including softening, melting, liquefaction, gasification, deformation, cracking, pyrolysis, coking, etc.). At this time, the force of the second conductive sheet (2) will force The limiting member (31) moves closer to the support member (32) at the X, and is no longer sufficient to force the first conductive sheet (1) and the second conductive sheet (2) to contact each other, thereby causing the first The conductive sheet (1) and the second conductive sheet (2) are opened relative to each other by the force to form an open circuit.

Please refer to the third and fifth figures again. In other words, under normal conditions, the first conductive sheet (1), the second conductive sheet (2), and the overheating destruction component (3) can be supported by the aforementioned support ( 32) Maintain the preset positional relationship. Using the limiting member (31) and the supporting member (32) to force the second conductive sheet (2) to contact the first conductive sheet (1) in the Y direction to form a path (such as a live path or a neutral path). When the working temperature of the first conductive sheet (1) or/and the second conductive sheet (2) is transferred to the overheating destruction component (3); when the overheating destruction component (3) is receiving an overheating that exceeds the working temperature At temperature, the force forces the limiting member (31) to change its relative position in the X direction, but cannot force the second conductive sheet (2) to contact the first conductive sheet (1), so that the second conductive sheet (2) Keep away from the first conductive sheet (1) to form an open circuit (for example, interrupt the live wire path or the neutral wire 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 damage component (3), so that the overheating damage component (3) ) Is not scattered randomly. For example, the blocking portion (315) of the limiting member (31) can be used to prevent the limiting member (31) from being directly separated from the first conductive sheet (1) and the second conductive sheet (2).

Please continue to refer to the sixth and seventh figures, which disclose the overheating and power-off structure of the conductive sheet of the second embodiment of the present invention.

Please continue to refer to the ninth and tenth figures. When the desired protection circuit has abnormal current or voltage conditions, which causes the first conductive sheet (1A) and the second conductive sheet (2A) to heat up, the first conductive sheet The heat of (1A) and the second conductive sheet (2A) will be conducted to the support (32A). When the support (32A) receives an overheating temperature that exceeds the operating temperature, it will be destroyed.
