Description
Technical field
The utility model is related to relay, more particularly to a kind of mute electromagnetic relay.
Background technology
Relay is a kind of using extensive electronic component, and it is applied to household electrical appliance, automobile, Industry Control, power train
The fields such as system, communication device.Electromagnetic relay operationally, due to armature and electromagnet adhesive clash into and dynamic and static contact
Closure clash into, certain noise can be produced, at present the operationally produced noise of electromagnetic relay on the market is universal all
In more than 70dB.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind and can reduce noise, while not reducing its original load
The mute electromagnetic relay of ability.
The utility model solve the technical scheme that adopted of above-mentioned technical problem for：A kind of mute electromagnetic relay, including
Base, outer casing and electromagnetic relay, described electromagnetic relay is arranged between described outer casing and described base, institute
Fixation on the base stated is plugged with auxiliary leading foot group, the lower end of each auxiliary leading foot in described auxiliary leading foot group to
Under pass described base, described auxiliary leading foot group includes the dynamic leading foot of auxiliary, aids in quiet leading foot and two boost lines
Circle leading foot, is provided with PCB connecting plates in described outer casing, the upper end of the dynamic leading foot of described auxiliary, described auxiliary are quiet
It is dynamic leading foot in upper end, the described electromagnetic relay of the upper end of leading foot and the ancillary coil leading foot described in two, quiet
Leading foot and two coil leading foots are inserted respectively in described PCB connecting plates and scolding tin is fixed, the dynamic leading foot of described auxiliary,
The upper end of the quiet leading foot of described auxiliary and the ancillary coil leading foot described in two respectively by described PCB connecting plates one by one
Accordingly electrically connect with the dynamic leading foot in described electromagnetic relay, quiet leading foot and two coil leading foots, described electricity
Puigging is provided between magnetic relay and described base, described outer casing.
Further, resistance is parallel between the ancillary coil leading foot described in two, effect is that suppression coil power-off is inverse
To electric discharge, the components and parts beyond electromagnetic relay are protected from relay impact failure.
Further, described resistance is arranged on described PCB connecting plates, and two connecting pins of described resistance are distinguished
Fix with the upper end scolding tin of the ancillary coil leading foot described in two.
Further, the material of described puigging is solid for porous low density polyethylene (LDPE), soft silicon rubber or soft epoxy
Change glue.
Compared with prior art, the utility model has the advantages that due to arranging sound insulation between electromagnetic relay and outer casing
Layer, while each leading foot of electromagnetic relay is drawn into base by corresponding auxiliary leading foot, need not be to original electricity
Magnetic relay carries out forming a brand-new mute electromagnetic relay on the premise of any structural modification so that the mute electromagnetic after
The noise that electrical equipment is operationally produced is less than 50dB, while and not reducing original load capacity of electromagnetic relay.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is partial exploded view of the present utility model；
Fig. 3 remove outer casing, puigging for the utility model after structural representation.
