Embodiment Construction

[0028] An embodiment of the leakage protection plug of the present invention, as Figure 1 to Figure 3 shown.

[0029] The leakage protection plug of the present invention includes a housing 100, a pin 200, a circuit board 300, a contact 410, a crimping terminal 400 and a fire damper 500;

[0030] The circuit board 300 , the contacts 410 , the crimping terminals 400 and the fire damper 500 are arranged inside the housing 100 ;

[0031] The contacts 410 and the crimping terminals 400 are arranged correspondingly;

[0032] The pin 200 is connected to the contact 410 or the crimp terminal 400 through the lower part of the housing 100 ;

[0033] The circuit board 300 is arranged on the upper part inside the housing 100;

[0034] The contact 410 is arranged on the lower part of the circuit board 300;

[0035] The fire damper 500 is disposed between the contact 410 and the housing 100 .

[0036] Before the fire damper 500 of the present invention is installed, the distance betw...

Abstract

The invention discloses a leakage protection plug which comprises a shell, a pin, a circuit board, a contact, a crimping terminal and a fire damper, wherein the circuit board, the contact, the crimp terminal and the fire damper are arranged inside the shell, the pin passes through the lower part of the shell to be connected with the contact or the crimping terminal, the circuit board is arranged in the upper part of the shell, the contact is arranged in the lower part of the circuit board, and the fire damper is arranged between the contact and the shell. By the adoption of the leakage protection plug of the invention, the risk that the plug shell is burned through when high-temperature heating and internal fire are generated due to poor contact between the contact and the crimping terminal inside the plug can be effectively reduced, fire and electric shock caused by plug firing can be avoided, and the safety of the plug is improved.

Description

technical field [0001] The invention relates to the technical field of plugs, in particular to an electric leakage protection plug. Background technique [0002] The existing leakage protection plugs with LCDI (leakage current detection circuit breaker) generally do not have special fire protection treatment for the contacts and the positions near the crimping terminals. [0003] An existing LCDI-containing plug is equipped with a flame-retardant fireproof board on the upper part of the contact, which can prevent fire from burning through the upper part of the contact. Due to the difference in the structure of the leakage protection plug, only a flame-retardant fireproof board is installed on the upper part of the contact, which cannot fully guarantee the fireproof performance of the plug. , the fire may burn out from the housing on both sides of the contact, and there are important defects in the fire performance of the plug. Contents of the invention [0004] Based on ...
