Abstract
The utility model discloses a contact means of starter, including base and apron, be equipped with the explosion chamber in the base and touch the bridge, be equipped with arc extinguishing bars piece in the explosion chamber, it is equipped with the movable contact to touch the bridge both sides, be equipped with the contact on the apron, be equipped with the stationary contact of aiming at the movable contact on the contact, characterized by: be equipped with the magnetic conduction board between apron and the contact, the magnetic conduction board has the extension that exposes in the contact, the extension is located arc extinguishing bars piece middle part top.
Description
Technical field
The utility model is related to a kind of contact apparatus of starter.
Background technology
At present, the contact apparatus of the starter that in the market is provided, including base and cover plate, are provided with arc-chutes and touch in base
Bridge, is provided with arc extinguishing grid pieces in arc-chutes, touch bridge both sides and be provided with movable contact, and cover plate is provided with contact, and it is dynamic tactile that contact is provided with alignment
The stationary contact of point, wherein contact extend directly to arc extinguishing grid pieces middle part top, and because contact is copper sheet, property that its is are-tight is poor, holds
Easily it is burnt.
The content of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide a kind of contact and is unlikely to be burnt
And the contact apparatus of the longer starter of service life.
Therefore, the utility model adopts the following technical scheme that to realize：
The contact apparatus of starter, including base and cover plate, are provided with arc-chutes and tactile bridge, the arc-chutes in the base
Arc extinguishing grid pieces are inside provided with, the tactile bridge both sides are provided with movable contact, and the cover plate is provided with contact, and it is dynamic that the contact is provided with alignment
The stationary contact of contact, it is characterized in that：It is provided with magnetic conductive board between the cover plate and contact, the magnetic conductive board has and exposes to contact
Extension, the extending part is in arc extinguishing grid pieces middle part top.
The contact is copper sheet, and the magnetic conductive board is iron plate.
After adopting the above technical scheme, be provided with magnetic conductive board between cover plate and contact, magnetic conductive board has and exposes to prolonging for contact
Extending portion so that the electric arc of arc-chutes first passes through magnetic conductive board again on contact, is unlikely to be burnt contact, and magnetic conductive board is iron plate,
Property that its is are-tight is higher than copper sheet, makes the whole service life of contact apparatus longer.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is internal structure schematic diagram of the present utility model.
Specific embodiment
Shown in reference picture 1, the contact apparatus of the starter that the utility model is provided include base 1 and cover plate 2, the base
It is provided with 1 in arc-chutes 3 and tactile bridge 4, the arc-chutes 3 and is provided with arc extinguishing grid pieces 5, the both sides of tactile bridge 4 is provided with movable contact 6, institute
State cover plate 2 and be provided with contact 7, the contact 7 is provided with the stationary contact 8 of alignment movable contact 6, it is characterized in that：The cover plate 2 and touch
Magnetic conductive board 9 is provided between piece 7, the magnetic conductive board 9 has the extension 10 for exposing to contact 7, and the extension 10 is located at arc extinguishing
The middle part of grid 5 top, the contact 7 is copper sheet, and the magnetic conductive board 9 is iron plate.
In the present embodiment, magnetic conductive board 9 is provided between cover plate 2 and contact 7, magnetic conductive board 9 has the extension for exposing to contact 7
Portion 10 so that the electric arc of arc-chutes 3 first passes through magnetic conductive board 9 again on contact 7, is unlikely to be burnt contact 7, and magnetic conductive board 9 is
Iron plate, property that its is are-tight is higher than copper sheet, makes the whole service life of contact apparatus longer.
