Problems solved by technology

High power consumption, high noise, and easy to burn coils or contacts during work, poor reliability
[0003] Moreover, the side-lock type direct-running AC contactor that was improved later, although it does not consume power, has no noise, and does not burn the coil during operation, has defects such as complex structure, large space occupation, and insufficient sensitivity and easy-to-burn contacts.

Embodiment 1

[0038] like figure 1 , figure 2 As shown: the present invention includes corresponding moving and static contacts, the moving contacts are installed on the movable ferrule 6, and the bottom of the movable ferrule 6 is fixed through the hanging plate 3 to attract the moving magnet 4 of the electromagnet, and the static contact Fixed on the static contact holder 7, the static contact holder 7 is fixed on the contactor base 15, between the hanging plate 3 and the contactor base 15 there is a static magnet 1 fixed on the contactor base 15, the static magnet 1 Two pull-in coils 19 are arranged on the top, and a locking mechanism is provided at the center of the static magnet 1 between the two pull-in coils 19-1 and 19-2.

[0039] like figure 2 , image 3 and Figure 4 Shown: the lock mechanism includes a lock tongue 11 and a lock pin, the lock pin is fixed on the hanging plate 3, the lock tongue 11 is connected to the opening and tripping frame that can be reset automatically...

Embodiment 2

[0046] like Figure 5 , Image 6 , Figure 7 Shown: the tripping trip frame includes a tripping pin 12, a tripping force arm 13 and a tripping shaft 23. The tripping pin 12 and the tripping force arm 13 are fixedly connected to the tripping shaft 23 respectively. The tripping shaft 23 is installed on the lock seat 16 , a release torsion spring 20 is installed on the release shaft 23 , and the lock tongue 11 is connected to the release switch pin 12 . The rest are the same as in Embodiment 1. The action of the tripping force arm 13 is transmitted to the tripping pin 12 through the tripping rotating shaft 23, so that the locking tongue 11 is moved, which also achieves the same purpose and achieves the same beneficial effect.

[0047] It can be seen from the above embodiments that the present invention has a simple structure, realizes voltage-free operation, does not consume power and has no noise; the tripping force is reduced, and it is easy to realize voltage-loss tripping; ...

Abstract

The invention relates to a straight-movement AC(Alternating Current) contactor with a lock catch arranged at the center, belonging to the technical field of low-voltage electric appliances. A moving contact is mounted on a moving mortice core, and a stationary contact is fixed on a stationary contact fixing stand which is fixed on a contactor base; a stationary magnet fixed on the contactor base is arranged between a hanger plate and the contactor base; and two attracting coils are arranged on the stationary magnet. The straight-movement AC contactor is characterized in that a lock catch mechanism is arranged at the central position of the stationary magnet between the two attracting coils; the lock catch mechanism comprises a spring bolt and a lock pin which is fixed on the hanger plate; the spring bolt is connected onto a brake separation tripping rack, and the brake separation tripping rack can restore automatically and is installed on a lock catch seat ; the lock catch seat is fixed on the stationary magnet; a brake separation tripper is correspondingly arranged at the outer end of a tripping force arm of the brake separation tripping rack; and the lower end of a stripping rod of the brake separation tripper contacts with the tripping force arm. The straight-movement AC contactor consumes no electric power and produces no noise during operation; the coils and the contacts can not easily be burned; and the straight-movement AC contactor is small in size, little in occupying room, and reasonable and compact in structure and is sensitive and reliable.

Description

technical field [0001] The invention relates to a central locking type direct-running AC contactor, belonging to the technical field of low-voltage electrical appliances. Background technique [0002] AC contactor is the most widely used electrical device in electrical equipment. The direct-running AC contactor includes corresponding moving and static contacts. The moving contact is installed on the movable ferrule, and the static contact is fixed on the static contact holder. The stationary contact holder is fixed on the base of the contactor, and the bottom of the movable ferrule is installed with a moving magnet that attracts electromagnets, and the corresponding static magnet below is installed on the base of the contactor. During operation, by supplying power to the pull-in electromagnet coil, suction force is generated between the moving and static magnets of the electromagnet, and the moving magnet pulls down the movable ferrule to make the moving and static contacts ...
