the utility model relates to an electromagnetic switch with rectifier bridge.
Background art:
some existing electromagnetic switches generally do not have a rectifier bridge, so that the coil part of the existing electromagnetic switch is large in overall size, heavy in weight and poor in suction force. CN2306565Y discloses an electromagnetic switch, which is not suitable for mass production because it requires an additional capacitor and has high cost and installation space, although a rectifier bridge is added.
The utility model has the following contents:
to the above problem, the utility model provides a simple structure, the coil quantity still less, light in weight, the suction force is good, the energy consumption is low, the electromagnetic switch that the cost is lower.
The utility model discloses a realize through following technical scheme:
a coil of the electromagnetic switch is connected to the output end of a bridge rectifier, and two input ends of the bridge rectifier are respectively connected to two output contacts of the electromagnetic switch.
Furthermore, one leg of the coil of the electromagnetic switch is connected to one output end of the bridge rectifier, and the other leg of the coil is connected to the other output end of the bridge rectifier through a series current limiting resistor.
In another preferred embodiment of the present invention, the coil of the electromagnetic switch is connected to the output terminal of the diode, and the two input terminals of the diode are respectively connected to the two output contacts of the electromagnetic switch.
Furthermore, one leg of the coil of the electromagnetic switch is connected to one output end of the diode, and the other leg of the coil is connected to the other output end of the diode through a series current limiting resistor.
After alternating current is converted into direct current for power supply, the current passing through the coil is larger, the coil is easier to heat, and the heating of the coil can be reduced by increasing the current-limiting resistor under the condition that the winding parameters of the coil cannot be further optimized.
The utility model has the advantages that: the utility model discloses an electromagnetic switch integrates rectifier bridge or diode in the switch, and the alternating current becomes the direct current after the rectification and lets in the coil, can strengthen the suction force greatly, reduces the quantity of coil simultaneously, and the output still is the alternating current, and its energy consumption is lower, and the cost of manufacture is lower.
