Description
Technical field:
The invention belongs to electric field, relate to a kind of relay, particularly relate to a kind of twin coil relay for automobile and assemble method thereof.
Background technology:
Relay is generally divided into communication relay, lathe relay, general-purpose relay and relay for automobile, and what market demand amount was larger is general-purpose relay and relay for automobile, mostly is suction type electromagnetic relay for relay for automobile.
Relay for automobile power switched is larger, therefore the fail safe of vehicle is considered, high to the requirement of relay for automobile, existing relay for automobile is commonly a coil, if vehicle is relay damaged in the process of moving, easily cause the accident, welding procedure is widely used for existing relay, because the volume of relay for automobile can not be excessive, therefore needing extreme care when manufacturing relay, the performance of relay can not be destroyed, and welding procedure needs high temperature, easily cause scald, manufacture process is more loaded down with trivial details, and production efficiency is not high.
Summary of the invention:
The object of the invention is to solve when general relay for automobile damages and there is no replaceable relay, cause unsafe problem of vehicle travel process and provide a kind of without the need to having welded the method that relay assembling is produced.
A kind of twin coil relay for automobile, comprise relay body and shell, it is characterized in that: described relay body comprises pedestal, be installed on the spill yoke one on pedestal and spill yoke two side by side, vertically be provided with the bobbin one of ribbon core in the groove of described spill yoke one, in the groove of spill yoke two, be vertically provided with the bobbin two of ribbon core; Described pedestal is provided with strip groove one near the outside of spill yoke one, and pedestal is provided with strip groove two near the outside of spill yoke two, is equipped with the resistance and light-emitting diode that mutually press in described groove one and groove two; Sheet metal has all been riveted in the top, one end of described spill yoke one and spill yoke two, the movable end bottom surface of described sheet metal is provided with moving contact, spill yoke three is provided with in the below of sheet metal movable end, the two ends, top of spill yoke three are provided with the fixed contact corresponding with sheet metal movable end bottom surface moving contact, and described spill yoke three and base contact face draw the common ground pin of two coils; Wherein, bobbin one, bobbin two are made by compound resin, (the percentage calculation) composed as follows of described compound resin: PC:40-60%, PMMA:8-20%, composite modifier: 5-20%, compound bulking agent: 5-10%, nano-MgO particle: 5-20%, processing aid: 3-10%, described composite modifier is ABS and polycarbonate-polysiloxane copolymer, and wherein both weight ratios are 2-3:1.
PC has that good light transmission, resisting heat distortion performance, high impact properties, hardness are high, good weatherability, and shortcoming is not ultraviolet resistance, not resistance to highly basic, is subject to the erosion of organic solvent.PMMA has splendid weatherability, higher case hardness, has good processing characteristics, have high transparency, but melt viscosity is higher, cooldown rate is very fast again, goods easily produce internal stress, require strict, also need to carry out reprocessing after product molding time therefore shaping to process regulation.PMMA has Room Temperature Creep characteristic, along with load increasing, time increase, can cause stress cracking phenomenon.Finished product is made in blended for PC and PMMA rear injection mo(u)lding, easily occurs lamination, thus affect the useful life of goods.The present invention is directed to the problems referred to above, the basis that PC, PMMA are blended by rational proportion adds composite modifier, compound bulking agent and nano-MgO, by the cooperative effect formed between each composition, improve the compatibility of each resin, significantly improve the combination property of compound resin, especially the stretching of compound resin, bending and notch impact strength and anti-scratch performance, and then improve the useful life of bobbin and twin coil relay for automobile.
