Heat destructive disconnecting switch and socket comprising same

Abstract

The present invention provides a heat destructive disconnecting switch and a socket comprising the same. The heat destructive disconnecting switch is composed of 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 enables conducting electricity to the first conductive member and the second conductive member. The operating component has an operating member and a first elastic member. The overheating destructive member butts against a limiting member, which causes a first spring to be compressed to between a contact member and the overheating destructive member, thereby providing the first spring with a first elastic force and providing the second elastic member with a second elastic force. When the overheating destructive member is destructed due to overheating, the first elastic force is smaller than the second elastic force, which causesthe movable conductive member to disconnect the first conductive member from 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 thermal breakage power-off switch and a socket with the switch, in particular to a power-off structure different from fuses and bimetal strips. The overheating breaker of the present invention does not rely on current passing to perform Destruction, and the destruction is performed by heat energy transfer and the switch is de-energized, and a socket with the switch. Background technique [0002] The existing rocker switch is to control the switch to pivot reciprocally in a certain angle range to control the access and disconnection of the switch. For example, China Taiwan Patent No. 560690 "Spark shielding structure of switch", when the switch pivots, use Locating features position it in a first position or a second position to create a path or break. [0003] In the existing press switch, each press operation can repeatedly control the on-off and off-circuit of the switch. The button utilizes a reciprocating button ...

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. The bimetal of the protection switch, but the price of the overload protection switch of the bimetal type is relatively high. If it is installed on each socket of the extension cord socket, the price will increase sharply, which is not conducive to popularization.
