Heat destructive disconnecting switch and socket comprising same

Abstract

The invention discloses a heat destructive disconnecting switch and a socket comprising the same. The heat destructive disconnecting switch comprises a first conductive member, a second conductive member, a movable conductive member, an overheating destructive member, an operating component, and a second elastic member. The movable conductive member conducts electricity to the first conductive member and the second conductive member. The operating component has an operating member and a first elastic member. The first elastic member and the second elastic member act on the operating member. The first elastic member is compressed and provided with a first elastic force, and the second elastic member is provided with a second elastic force. When the overheating destructive member is destructed due to overheating, the first elastic force is diminished or vanishes, causing the second elastic force to be larger than the first elastic force. Consequently, the movable conductive member disconnects the current conducting state between the first conductive member and the second conductive member, thereby achieving a protective effect from overheating. The socket comprises the heat destructive disconnecting switch.

Description

Technical field [0001] The present invention relates to a thermally destructive power-off switch and a socket with the switch, in particular to a power-off structure that is different from a fuse and a bimetallic strip. The overheating destructive component of the present invention does not rely on the passage of current to perform Destroy, and perform destruction by means of heat transfer and power off the switch, and a socket with the switch. Background technique [0002] The existing rocker switch controls the switch to pivot to and fro within a certain angle range to control the passage and disconnection of the switch. For example, Taiwan Patent No. 560690 "Spark Shielding Structure for Switching Switches" uses the The positioning feature locates it in a first position or a second position to form a path or a disconnection. [0003] The existing push switch can repeatedly control the switch's passage and disconnection every time it is pressed. The button uses a reciprocating b...

AI Technical Summary

Problems solved by technology

[0008] 1. The metal pins of the plug are severely oxidized, and the metal pins are covered with oxides. When the plug is inserted into the socket, the oxide with poor conductivity will increase the resistance and the socket will overheat.

[0009] 2. When the metal pin of the plug is inserted into the socket, the insertion is not complete, resulting in only partial contact, and the too small contact area causes the socket to overheat

[0010] 3. The metal pins of the plug are deformed or worn, resulting in incomplete contact when inserted into the socket, and too small contact area causes the socket to overheat

[0011] 4. The metal pins of the plug or the metal sheet of the socket are stained with foreign matter, such as dust or dirt, which makes the conductivity poor, so the resistance becomes larger and overheats

[0014] Since there are many situations that cause the socket to overheat, and the distance between the socket and the bimetal of the overload protection switch will cause a huge temperature difference, in order to effectively achieve overheat protection, an overload protection should be set on each socket of the extension cord socket. Protection switch, but the price of the bimetal type overload protection switch is relatively high. If it is installed on each socket of the extension cord socket, the price will rise sharply, which is not conducive to popularization.
