Overheating damage component of switch, switch, socket and assembly method thereof

Abstract

The invention provides an overheating damage assembly of a switch and its switch, socket and assembly method. The overheating damage switch includes: a base, a first conductive part, a second conductive part, a movable conductive part, an overheating damage part, An operating component and a second elastic member. The movable conductive part is connected to the first conductive part and the second conductive part. The operation component includes an operation part and a first elastic part, and the first elastic part is limited between a contact part and the overheating damage part and has a first elastic force. The second elastic force of the second elastic member acts on the operating member. The overheating destructive element is destroyed at the destructive temperature, so that the first elastic force becomes smaller or loses, and the second elastic force will force the operating element to move, so that the movable conductive element is separated from the second conductive element to form a power failure.

Description

technical field [0001] The invention relates to an overheating damage switch, an assembly method of an overheating damage component and an overheating damage part, and a socket with a switch, in particular to a power-off structure different from a fuse and a bimetal strip. Instead of relying on the passage of current to destroy, the device relies on the transfer of thermal energy to destroy and de-energize 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 struc...

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.
