Description
【Technical field】
A kind of magnetic latching relay is the utility model is related to, more particularly to a kind of antioverloading magnetic latching relay.
【Background technology】
Magnetic latching relay is a kind of new type of relay to grow up in recent years, and a kind of automatic switch.And other
Electromagnetic relay is the same, and turn on automatically and cutting action are played to circuit, and overload behavior, mistake often occurs in electrical equipment when in use
Load frequently can lead to circuit and burn, and damage electrical equipment, trigger fire, and magnetic latching relay does not possess antioverloading function at present, disconnected
It can not be alarmed when electric, be not suitable for being arranged on and shake on larger electrical equipment.Therefore, it is proposed that a kind of antioverloading magnetic keeps relay
Device.
【Utility model content】
Main purpose of the present utility model is to provide a kind of antioverloading magnetic latching relay can effectively solve background skill
The problem of in art.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of antioverloading magnetic latching relay, including protective cover and magnetic latching relay body, the protective cover is interior to be set
Have a magnetic latching relay body, the magnetic latching relay bodies top and bottom are provided with cushion pad, the magnetic keep after
Electrical equipment body side is provided with power-off alarm, and the power-off alarm side is provided with overload protective device, the power alarm
Device and overload protective device are electrically connected with magnetic latching relay body, and the power-off alarm and overload protective device are installed in
On the inside of protective cover.
Further, the protection cover inner surface applies covered with fire resistant coating, the protection cover outer surface covered with insulation
Layer.
Further, the protective cover both sides are provided with threading hole.
Further, the overload protective device and power-off alarm are electrical connected with power bus.
Compared with prior art, the utility model has the advantages that：Relay is kept in magnetic by overload protective device
When device load current exceedes a certain numerical value, overload protective device is threaded off and carries out open circuit protection to power bus automatically, avoids burning magnetic
Guard relay, triggers fire, and power-off alarm is alarmed after circuit disconnection, reminds staff to safeguard in time, pass through
Upper lower cushion fixes relay body, avoids larger vibration influence magnetic latching relay from working, is adapted for mount on vibrations
Used on larger electric equipment, the fire resistant coating on protective cover can prevent that magnetic latching relay work is fiery caused by bad
Flower triggers fire, and insulating coating can avoid electrical equipment effect of leakage magnetic latching relay from working.
【Brief description of the drawings】

【Embodiment】
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As shown in Figure 1-2, a kind of antioverloading magnetic latching relay, including protective cover 3 and magnetic latching relay body 4, institute
State and magnetic latching relay body 4 is provided with protective cover 3, the top and bottom of magnetic latching relay body 4 are provided with slow
Pad 5 is rushed, the side of magnetic latching relay body 4 is provided with power-off alarm 2, and the side of power-off alarm 2 was provided with
Protector 1 is carried, the power-off alarm 2 and overload protective device 1 are electrically connected with magnetic latching relay body 4, the power-off
Alarm 2 and overload protective device 1 are installed in the inner side of protective cover 3.
Wherein, the inner surface of protective cover 3 is covered with fire resistant coating 7, and the outer surface of protective cover 3 is covered with insulating coating
8。
Wherein, the both sides of protective cover 3 are provided with threading hole 6, for threading wiring.
Wherein, the overload protective device 1 and power-off alarm 2 are electrical connected with power bus.
It should be noted that the utility model is a kind of antioverloading magnetic latching relay, protected by overload protective device 1 in magnetic
When holding the load current of relay body 4 and exceeding a certain numerical value, overload protective device 1 is threaded off and carries out breaking guarantor to power bus automatically
Shield, avoid burning magnetic latching relay, trigger fire, power-off alarm 2 is alarmed after circuit disconnection, reminds staff
Safeguard, fixed magnetic latching relay body 4 in time by upper lower cushion 5, avoid larger vibration influence magnetic from keeping relay
Device works, and is adapted for mount on the larger electric equipment of vibrations and uses, the fire resistant coating 7 on protective cover 3 can prevent magnetic from keeping
Relay work it is bad caused by spark trigger fire, insulating coating 8 can avoid electrical equipment effect of leakage magnetic keep after
Electrical work.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
