Meishuo-advantages And Features Of Automotive Electrical Control Relay
- May 13, 2018 -

With the rapid development of the automobile and the improvement of the national living standard, the reliability of the automobile has been raised more and more. As a main control component of the car, the relay needs a higher level, especially the reliability of the relay at high temperature, such as the newly issued by the German Volkswagen. The VW80000 - 2009 standard of the cloth is to replace VW80101, which has been implemented for many years, which has added a new high temperature endurance test project. Domestic auto manufacturers, such as SAIC and Chery, have not directly corrected their standards, but in the design and verification of the new relay, they also refer to the general GMW1 5267 standard, adding some similar over Test items such as load, high temperature durability and durability. In order to improve and improve the product of the standard, we use high temperature resistant material in the plastic parts of the product. The polyester imide enameled wire is used for the special coating line. The original F/H class polyurethane (UEW) enameled wire can be used, but the 180 grade polyester imide (EIW) enamel line with high thermal shock resistance is now used, and so on.

Under the joint efforts of the motor vehicle project team, Mei Shuo electric technology has developed a number of auto control relay products, including MAA1/ MAH2/ MAA/ MAB/ MAD/ MAG/ MAV and so on; for car start / car light / car resistance control. The products are fully covered with the needs of automobile control and conversion; Mei Shuo electric technology R & D, production and sales of Automobile Relays for many years; on the basis of fully absorbing technology and management at home and abroad; combining the advanced technology and customer feedback at home and abroad; optimizing the design of the relay in the structure of the relay; and raising the product Reliability.

Product structure features:

1, press resistance device: the same industry uses spot welding and splitting pressure to connect resistance and diode, its processing is complex, processing technology is various, and the cost of production equipment is high, and the residue of spot welding and cutting and riveting metal often leave the product with hidden trouble. In order to avoid the risk, we use the new structure to replace the resistance directly into the base, and the resistance is directly pressed and fixed by the clip of the lead foot while entering the magnetic circuit. Compared to the competitor's structure, its features are simple and simple in process, and the spot welding equipment and the splitting riveting process are not put in, the hidden danger of quality remains and the processing cost of the product is reduced relatively.

Description: resistance is pressed into the base slot by pin groove.

2, armature anti vibration structure: the automobile use the harsh environment, especially in the vibration on the relay's anti vibration capacity requirements, so after the renewal and replacement of the MAA in the armature design 2 limit convex block, the armature collocation in the yoke mouth position limit, to prevent external vibration and fall to the reed to produce deformation, thus improving the product The stability of the parameters can enhance the service life of the relay.

Description: the armature is fixed by 2 bumps, and the armature is fixed to play the role of reed.

3, the yoke lead end uses the copper riveting. The yoke lead end of the same industry is often the yoke iron part. After the replacement, the MAA adopts the form of the yoke lead and the yoke iron to be connected by the cone rivet separately, and the lead is made of copper material. The automobile relay has a complex environment and high requirement for salt fog. Its advantage greatly improves the salt fog performance of the product and the rated current of the product in the case of sealing. It can reach 35A (competitor 30A), and the life of the product is above 13W.

4. Appearance: after the product is updated, all high-precision electrical pulses are applied to the shell and the base cavity to make the appearance of the shell and base more delicate and exquisite. And the use of laser printing, to avoid hidden dangers of traditional ink printing. The design of shell and pedestal is designed to make the product look more sleek and beautiful.

5. The model flow analysis method is used to analyze the product first, and the model flow analysis is used in the product design for the first time in the relay industry, and the product reliability is guaranteed from the product design.
