Body part, and opening is formed backwards to the cavity of the contact system, it is characterised in that it further include the clamping groove, the card
A side of the pedestal is arranged in the notch of access slot, and first divider wall is provided on the pedestal, described
Clamping groove include the first clamping portion and the second clamping portion, the bottom with the opposite insulating boot of opening of the insulating boot
Portion, first divider wall, the pedestal composition first clamping portion, second clamping portion is arranged described
Insulating boot below the pedestal on.
The vertical section of second clamping portion of the clamping groove be in ┒ type, can increase to greatest extent so dynamic contact feet with
The distance between quiet contact feet.
The contact system includes dynamic contact group and quiet contact group, the push rod include it is described push away seat and two with
The push arm for pushing away seat and being wholely set, the seat that pushes away are connected with the disk pack of the electromagnetic system, push away described in two
The front end of arm is provided with clamping portion, and there are two groove, the dynamic contact groups to move for clamping portion setting symmetrical above and below
The top of contact chip be symmetrically set with two it is corresponding with the push arm push away slot, the clamping portion of the push arm is caught in
Described pushes away slot, thus it is possible, on the one hand, moving contacting plate return when, push rod auxiliary pull moving contacting plate return, thus increase after
The sensitivity of electric appliance；On the other hand, simple and convenient when assembling push rod, improve production assembly efficiency.
There are two spacing is corresponding with the push arm to each self-supporting institute for the upper end setting of the insulating boot
The step for the push arm stated, push arm described in two pass through corresponding step, in this way, keeping push rod more steady when pushing moving contacting plate
It is fixed and easy to assembly.
The quiet contact group is an integral structure, in this way, further reducing the part of product, increases assembly efficiency,
To consistency of enhancing product performance.
The dynamic contact group is an integral structure, in this way, further reducing the part of product, increases assembly efficiency,
To consistency of enhancing product performance.
Compared with prior art, the utility model has the advantages that since a side of pedestal is arranged in the notch of clamping groove
Face, is provided with the first divider wall on pedestal, and clamping groove includes the first clamping portion and the second clamping portion, opposite with the opening of insulating boot
The bottom of insulating boot, the first divider wall, pedestal form the first clamping portion, the pedestal below insulating boot is arranged in the second clamping portion
On, i.e. the clamping groove side that abuts against insulating base meets the pitch requirements of dynamic and static contact group leading foot, and give magnetic circuit system
System leaves very large space, so that disk pack can be added under the space of restriction, so as to realize magnetic latching relay function
Energy；On the other hand, pedestal and insulating boot integral structure, dynamic contact group, quiet contact group are also all structure as a whole accordingly, move contact
Group, quiet contact assembling timing, it is simple and fast as long as being caught in pedestal from side can be completed installation, improve production assembly efficiency.
