Taiwan patent No. 321352, "improvement of on-line switch structure", discloses a switch structure with a fuse, but the fuse is located in the path of the power line, and needs to rely on the passing of current for protection, especially the over-current can melt the fuse, since the fuse needs to pass the current during operation, but must be melted when the current is too large, so the low melting point lead-tin alloy and zinc are often used as the fuse, and the conductivity is much lower than that of copper. Taking an extension cord socket as an example, the extension cord socket mainly uses copper as a conductor, and if the extension cord socket is combined with the switch of taiwan patent No. 321352 to control the power supply, the conductivity of the fuse is poor, and the problem of energy consumption is easily caused.

Detailed Description

In view of the above technical features, the main functions of the rocker switch and the sliding pressing member thereof according to the present invention will be apparent from the following embodiments, wherein the sliding pressing member is a part of the rocker switch and is used to control the power on or off of the rocker switch.

Referring to fig. 1 and 2, the rocker switch of the present embodiment includes:

a base body 1L having a receiving space 11L. A first conductive member 2L and a second conductive member 3L are disposed through the base 1L. A warping plate conductive member 4L disposed in the accommodating space 11L, the warping plate conductive member 4L straddles the first conductive member 2L and is electrically connected to the first conductive member 2L. An operating component 6L for operating the rocker conductive member 4L to connect the first conductive member 2L and the second conductive member 3L or to disconnect the first conductive member 2L and the second conductive member 3L. When the operating temperature is abnormally increased, it is preferable that the break is generated in the live wire, so that the first conductive member 2L is used as the first end of the live wire, and the second conductive member 3L is used as the second end of the live wire, so that a live wire path is formed when the first conductive member 2L and the second conductive member 3L are conducted by the seesaw conductive member 4L, and a live wire break is formed when the first conductive member 2L and the second conductive member 3L are disconnected by the seesaw conductive member 4L.

The operating component 6L is assembled on the base 1L, and includes an operating element 61L and a first elastic element 62L, the operating element 61L has a pivot point 611L, and the pivot point 611L is pivoted to the base 1L, so that the operating element 61L can rotate back and forth with the pivot point 611L as an axis to a limited extent. The operating element 61L further includes a sliding pressing member and a limiting member 612L, and the sliding pressing member slides on the wane conductive member 4L, so that the wane conductive member 4L contacts or separates from the second conductive member 3L in a wane movement pattern. The sliding pressing member includes a heat conducting casing 613L and an overheating destructive member 5L, the heat conducting casing 613L has a recessed receiving chamber 6133L and an inner surface 6134L surrounding the receiving chamber 6133L, and the overheating destructive member 5L is placed in the receiving chamber 6133L and tightly attached to the inner surface 6134L. Wherein the overheating damage part 5L can be damaged at a damage temperature which is between 100 ℃ and 250 ℃. The heat conducting casing 613L further comprises an open end 6131L and an arc-shaped contact end 6132L, wherein the contact end 6132L contacts the rocker conductive member 4L. It should be noted that the overheating breaking element 5L is not used to maintain the continuous supply of electric current, and therefore, an insulating material such as plastic, or a low melting point alloy such as bismuth alloyed with any one or more of cadmium, indium, silver, tin, lead, antimony, and copper, or other low melting point metals with a melting point between 100 ℃ and 250 ℃ may be used, and the tin-bismuth alloy has a melting point between 138 ℃ and 148 ℃ depending on the composition, which is a preferred material. The limiting member 612L is provided with an inward concave accommodating space 6121L, the accommodating space 6121L is provided with an opening 6122L, the first elastic member 62L is placed in the accommodating space 6121L, the heat-conducting shell 613L is connected with the limiting member 612L to close the opening 6122L, so that the first elastic member 62L extends into the heat-conducting shell 613L from the opening end 6131L and abuts against the overheating destructive member 5L, the first elastic member 62L is compressed to have a first elastic force, the width of the first elastic member 62L is substantially equal to that of the opening end 6131L of the heat-conducting shell 613L, and the width of the first elastic member 62L is slightly smaller than that of the opening end 6131L of the heat-conducting shell 613L, so that the first elastic member 62L can move along a set track.

The rocker switch of this embodiment further has a second elastic member 7L, the second elastic member 7L is a spring in this embodiment, and the second elastic member 7L has a second elastic force acting on the operating member 61L and the rocker conductive member 4L.

Referring to fig. 3, a user operates the operating element 61L to rotate around the pivot point 611L, so that the heat conductive shell 613L slides on the rocker conductive element 4L, and drives the rocker conductive element 4L to selectively contact or separate from the second conductive element 3L in a rocker motion mode. When the heat conductive casing 613L slides on the rocker conductor 4L in a direction toward a silver contact 41L on the rocker conductor 4L, the moment of the first elastic force acting on the rocker conductor 4L is greater than the moment of the second elastic force acting on the rocker conductor 4L, so that the silver contact 41L is forced to contact the second conductor 3L to form a power-on state.

Referring to fig. 1 and 4, when the external conductive device connected to the first conductive member 2L or the second conductive member 3L is in an abnormal state, for example, the external conductive device is a socket, when oxides, dust, incomplete insertion of metal pins, deformation of metal pins, etc. exist between the metal pins of the plug and the socket, the conductive portion of the socket generates large heat energy, and the heat energy is transferred to the rocker conductive member 4L through the first conductive member 2L or the second conductive member 3L, and then transferred to the overheating destructive member 5L through the heat conductive shell 613L, and the overheating destructive member 5L absorbs the heat energy and gradually reaches its melting point, for example, the material of the overheating destructive member 5L is a tin-bismuth alloy, although its melting point is 148 ℃, but starts to lose rigidity when approaching the melting point, so that under the action of the first elastic force, the overheating breaking element 5L is pressed and deformed by the first elastic element 62L, even breaks through the overheating breaking element 5L, the first elastic force is reduced or lost, and the moment of the second elastic force acting on the rocker conductive element 4L is greater than the moment of the rocker conductive element 4L acting on the first elastic force, so that the silver contact 41L of the rocker conductive element 4L is separated from the second conductive element 3L. Referring to fig. 1 and 4, after the overheating destructive element 5L is disposed in the accommodating chamber 6133L, a height difference exists between the overheating destructive element and the opening end 6131L, so as to prevent the overheating destructive element 5L from overflowing into the accommodating chamber 6133L when the first elastic element 62L is damaged due to overheating of the overheating destructive element 5L. It should be further noted that, in this embodiment, the arrangement direction of the first conductive member 2L and the second conductive member 3L defines a longitudinal direction, the operating member 61L has a length in the longitudinal direction, the first elastic member 62L is disposed at a central position of the length, and the second elastic member 7L is disposed at a distance from the central position, so that when the second elastic force is greater than the first elastic force, the operating member 61L can rotate around the pivot point 611L due to the action of moment, and drives the heat-conducting shell member 613L to slide on the rocker conductive member 4L to force the operating member 61L to move to the closed position, and the silver contact 41L of the rocker conductive member 4L is separated from the second conductive member 3L, thereby forming a power-off state, and thus achieving the overheat protection effect. In addition, the overheating breaking element 5L abuts against the inner surface 6134L of the heat conducting casing 613L, and can completely absorb the heat energy generated by the passage, thereby having the advantage of high sensing sensitivity.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
