Electric leakage protection socket with function of reverse wiring protection

Abstract

The invention provides an electric leakage protection socket with a function of reverse wiring protection, and the socket comprises a main loop switch and an electromagnetic release mechanism, and also comprises a lifting part. Two sides of the lifting part are respectively provided with a metal rod in a sleeving manner. The lower end of the metal rod is sleeved by a reset spring, and the upper end of the metal rod is in contact connection with a movable metal piece. The reset spring of a zero line metal rod and a static metal piece form a reverse wiring loop switch. The lifting part is cooperatively provided with a locking part, and the head of the locking part abuts against a side wall of the lifting part. The electromagnetic release mechanism comprises an iron core, and the iron core is provided with a driving disc. During reverse wiring, the iron core pulls the lifting part downwards, and the head of the locking part covers the top of the lifting part under the action of an elastic resetting mechanism. The beneficial effects of the invention are that a main loop switching mechanism is reasonable and ingenious in structure, and is quick in response; during reverse wiring, the lifting part is driven by the iron core to sinks for automatic releasing; moreover, the locking part automatically locks the lifting part; the reset button cannot achieve the resetting; the socket is safe for use.

Description

technical field

[0001] The invention relates to the field of power sockets, in particular to a leakage protection socket with reverse wiring protection function. Background technique

[0002] Existing leakage protection sockets, for example (invention patent with patent number 201010248157.8), generally include a housing, an output conductor, a power input terminal, and a power output terminal, which are used to close the main circuit switch and cooperate with the locking mechanism to maintain the closed state of the main circuit switch. Furthermore, the reset button that keeps the power supply input terminal, the power supply output terminal and the output conductor conducting, and the electromagnetic tripping mechanism used to disconnect the main circuit switch when a leakage current is generated, etc., the metal sheets drawn from the input terminal and the output terminal must be at least one For the elastic metal sheet, the length of the elastic metal sheet is long and o...

Embodiment 1

[0034] refer to Figure 1 to Figure 9 As shown, the earth leakage protection socket with reverse wiring protection function of the present invention includes main circuit switches (L10, L40) (L30, L40) (N10, N40) (N30, N40), middle bracket 4, reset button 001, off The buckle coil 7 and the electromagnetic tripping mechanism also include a lifter 9, and a metal rod 10, 11 is respectively set on both sides of the lifter 9C, and the lower ends of the metal rods 10, 11 are set with return springs 007, 008, and the upper ends of the pair of metal rods are connected correctly. In this state, it is in contact with the moving metal pieces (N4, L4) of the main circuit switch, and the return spring 008 of the neutral line metal rod 11 and a static metal piece K9 located below the zero line metal bar return spring 008 form a tripping coil 9 circuit In the reverse wiring path switch of normal close, the upper ends of the neutral wire metal rod 11 and the live wire metal rod 10 are kept in...

Embodiment 2

[0043] refer to Figure 3-1 The difference between this embodiment and Embodiment 1 is that the bottom of the middle bracket is open to form a sliding fitting area for the locking piece to be put in, and the middle bracket and the locking piece are combined to form a sliding limit through the combination of the convex nail 3D or the buckle plate mechanism. All the other structures are basically the same as the first embodiment. Convex nails are integrated on both sides of the locking piece.

Embodiment 3

[0045] refer to Figure 3-2 The difference between this embodiment and Embodiment 1 is that a cover plate is arranged above the locking member, and the cover plate has a through hole or a gap for the guide column of the reset button and the guide column of the test button to pass through. The bracket is hooked and positioned with a positioning convex nail, and above the positioning convex nail, there is a relief defect area that is convenient for snapping into the middle bracket. All the other structures are basically the same as the first embodiment.
