CN201413803Y - Change-over switch of power-saving contactor - Google Patents

Abstract

The utility model discloses a change-over switch of a power-saving contactor, comprising a shell, a pushing rod, a static contact and a moving contact which is movably arranged on the pushing rod; pressure springs are arranged between the bottom part of the pushing rod and the shell; the change-over switch is provided with protective covers at two sides thereof and has the advantage of compact andsimple structure; and in the process of absorbing a moving iron core of the contactor so as to extrude the pushing rod, the moving contact and the static contact are separated gradually under the function of the two pressure springs. The change-over switch plays a role of connecting and cutting off, has stable working and reliable performance, does not cause wearing to the moving contact and thestatic contact and prolongs service life.

Description

Economize on electricity contactor change over switch

Technical field

The utility model relates to the economize on electricity contactor change over switch in a kind of low-voltage electrical apparatus field.

Background technology

Existing A.C. contactor has not only taken an auxiliary normally closed interlock, and owing to the often improper instability that causes circuit working of mechanical constant of contact.Chinese patent 88205508.9 discloses a kind of ac contactor silent energy-saving coil, and this product is intended to overcome above-mentioned defective, is made of three U font sheet metals, and wherein two U word slices are connected on the circuit two ends relatively and respectively as fixed contact, U word bottom.Another U word slice is connected between two U word slices of fixed contact as moving contact, its U word opening part attaching has a moving contact depression bar, another termination of depression bar passes the magazine end face and just places between the armature, the contact of this structure is the line contact, capacity is little, circuit working is unstable, and there is friction between the sound sheet, influences useful life.

The utility model content

The purpose of this utility model provides the economize on electricity contactor change over switch of a kind of stable work in work, simple in structure, long service life.

In order to achieve the above object; the solution that the utility model is taked is: economize on electricity contactor change over switch comprises shell, push rod, fixed contact and is actively installed on moving contact on the push rod; be provided with stage clip between push rod bottom and the shell, both sides are provided with protective cover, form change over switch.

Description of drawings:

Fig. 1: the structural representation of change over switch

Among Fig. 1, shell (1), push rod (2), fixed contact (3) and moving contact (4), stage clip (5), (8), prerotation vane (6), (7), protective cover (9), (10)

Specific embodiments:

Below in conjunction with embodiment and accompanying drawing thereof utility model is remake description.

Referring to figure, a kind of economize on electricity contactor change over switch comprises shell (1), push rod (2), fixed contact (3) and is actively installed on moving contact (4) on the push rod (2).And be provided with arc-extinguish chamber (9), (10), and being provided with stage clip (5) between push rod (2) bottom and the shell (1), moving contact (4) can be set on the push rod (2).On the push rod (2) of moving contact (4) below, be movably equipped with prerotation vane (6), (7), between be provided with stage clip (8).When the starting of economize on electricity contactor, make iron core by adhesive, and the push rod of extruding change over switch, make the change over switch disjunction, when the release of economize on electricity contactor, change over switch is connected.Change over switch reaches in economize on electricity contactor running and plays adhesive to keeping transformation.

The utility model can be integral all component sets, compact conformation, simple, the moving iron core of economize on electricity contactor by adhesive pressure-ram process in, dynamic/static contact breaks away under two stage clip effects gradually, and circuit working is stable, dependable performance, and there are not wearing and tearing in dynamic/static contact, has improved useful life.The utility model also can be applicable on the electric equipment products of electromagnet.

Claims (3)

1, a kind of economize on electricity contactor change over switch.The change over switch that is characterised in that of the present utility model.Comprise shell (1), push rod (2), fixed contact (3) and be actively installed on moving contact (4) on the push rod (2), be provided with stage clip between push rod (2) bottom and the shell (1).

2, economize on electricity contactor change over switch according to claim 1 is characterized in that being being movably equipped with on the push rod (2) prerotation vane (6), (7), between be provided with stage clip (8).

3, economize on electricity contactor change over switch according to claim 1, its feature is provided with protective cover (9), (10) on the shell both sides.
