Immediately after cleaning and drying, ventilation should be applied to bring the relay down to room temperature. 2.Mounting Orientation The correct mounting orientation is important to achieve optimal relay performance.
The ideal installation direction of shock resistance is to make the contacts and moving parts (armature part) perpendicular to the direction of vibration or impact in the direction of movement, especially when the normally open contact ** ring is not excited, its vibration and shock resistance is greatly affected by the installation direction of the relay. The installation direction of the contact reliability relay should be so that the contact surface is perpendicular to prevent pollution and dust from falling into the contact surface, and it is not suitable to convert large load and low level load on one relay at the same time, otherwise it will affect each other. When many relays need to be installed next to each other, due to the superposition of heat generated, it may lead to abnormal high temperature, so there should be enough clearance between each other (generally 5mm) to prevent heat accumulation.
In any case, it should be ensured that the ambient temperature of the relay does not exceed the sample specification. When using the socket, ensure that the socket is installed firmly, the relay pins are in reliable contact with the socket, the mounting holes are well matched with the socket, and the socket and relay mounting bracket are used correctly. Selection of connecting leads.
If it is necessary to connect the relay with a lead, the lead wire with an appropriate cross-sectional area should be selected according to its load size, and the following table shows the cross-sectional area of the current and the lead wire that should be selected. 3.Transportation and installation The relay is a kind of precision machinery, so it is very sensitive to the abuse of the mode of transportation, many methods have been adopted in the manufacturing process to make the relay get the best protection during transportation, so in the factory inspection and the user's later use and installation, do not destroy the initial performance of the relay, in addition to the following points should be noted:
To prevent contamination of the surface of the lead-out end, direct contact with the lead-out should not be made, otherwise, it may result in a decrease in solderability. The position of the lead end should be consistent with the hole position of the printed plate, any improper fit may cause dangerous stress on the relay, impairing its performance and reliability, please follow the punch diagram in the sample to punch the hole. Care should be taken to monitor the storage temperature and try to avoid storing the relay for too long (no more than three months is recommended).
Relays should be stored and installed in a clean environment. 4.Flux Coated Non-plastic relays are highly susceptible to flux contamination and are recommended to use flux-resistant or plastic relays to prevent flux gas from ingress from the lead end and the gap between the base and the housing, and are suitable for multi-bubble flux or spray flux processes.
Solder resistant relays are preheated and dried to further prevent flux ingress. 5.Soldering process When using flux or automatic soldering, care should be taken not to damage the relay performance, flux-resistant relays or plastic relays can be suitable for dip soldering or wave soldering processes, but the maximum soldering temperature and time should be controlled according to the relay selected.

The correct wiring method for relays is to turn the circuit on or off directly with the contacts of the relay.
The purpose of the relay itself is to use weak electricity to counterbalance strong electricity. The connector of the relay is the contact connector of the control circuit and the connector of the control coil.
If it is a four-corner relay, then it is necessary to use ABCD to describe its four sides, and at this time it is necessary to make sure that it has two sides that belong to the control angle. If it is a triangular relay, then one of its ports should be connected to the load, and the other interface should be connected to the power supply, which is a common interface, and the remaining other interface should be connected to the button.
Considerations for selecting relays
1. When selecting a relay, it is necessary to understand the load and type of its contact, because the contact method of the relay of the same model is different, with multiple groups of contacts and single group contacts. When selecting a relay, you can choose the type of contact.
2. And when selecting, its own rated current must be within the standard range. And the relay is a transistor used, so its rated current is lower than its own output current of the relay, and its own volume should also be understood.
3. When selecting a relay, it is necessary to understand its voltage and coil power supply clearly. For electromagnetic type relays, it is necessary to know whether it is AC or DC, and what voltage it is rated to work at. In the case of a normal type, it is lower than its own operating voltage.

Summary. The starter relay is in the fuse box in the engine compartment. The function of the starter relay is mainly to control the current of the high-voltage line by controlling the current of the low-voltage line, and play the role of current switch.
The starting relay is one of the components of the starting system, which is mainly used in the automobile to control the rotation of the motor in a small current control and high current mode, so as to drive the magneto rotor inside the generator to rotate, input the ignition pulse signal to the igniter, and make the igniter produce an electric spark, ignite the mixed gas in the cylinder and do work.

The starting relay is one of the components of the starting system, and its main role in the car is to start the rotation of the Mashan stool in a small current control and large current mode, so as to drive the internal magneto rotor of the motor and slide motor to rotate, and input the ignition pulse signal to the igniter, so that the igniter can produce an electric spark, ignite the mixed gas in the cylinder and do work.
Will the starter relay have anything to do with one-button start?
It will have a little to do with it.
Oh, his key choice is to turn on a switch, turn off a power supply, how to get it.
That is, after connecting all the lines, click one button to turn on.
There's no electricity over there with a one-button start.
It may be that the line is not connected, you can check it.
The lines are all good.
Where is the relay of the starter installed?
The starter relay is in the fuse box in the engine compartment.

Starter Relay Installation Position Hello dear! Starter relays have battery B, button S, start, and negative pole respectively. Battery B is connected to the position of the starter electromagnetic switch live wire, and the button S is connected to the position of the ignition switch 3 pins, and the smallest starter is connected to the screw, and then the negative electrode is hit with the iron chain.
The start-up relay can be installed on the starter or elsewhere. There is a control terminal on the starter, and the starter will start the vehicle after this terminal is connected to the positive pole of the power supply. However, this magnetic switch generates a large current when it is engaged, and the switch contacts can easily be burned out.
So we use the starter relay to withstand this current, and connect one of the wires in parallel to the main power supply, and the other wire to the starter control end. Control the termination key key to ignite. Starting relays, there may be many forms, what 3 feet and 4 feet, the color of the line will be different because of different models, but the principle is the same.
It is to ensure that the coil of the relay is connected into a loop, and the contact of the start button is strung together, and the output contact of the relay is connected in series with the coil of the motor, so that two circuits are formed, a control loop and a main loop. Hope it helps!

The starting relay can be installed like this: 1, respectively, the button S, the battery B, the start, the negative pole, the battery B are connected to the position of the starter electromagnetic switch live wire, the button S and the ignition switch triangle position, the smallest screw rod that is connected to the starter is started, and then the negative electrode is ironed; 2. If it is a triangular kind of starting relay, there is no mark on it, the general black wire is iron, and then the other 2 wires are connected to the minimum binding post of the live wire and the starter electromagnetic switch, and it is not important that the 2 electric good luck lines are reversed; 3. There are two very thick wires with screws, a positive pole of the battery, and a terminal pile connected to the starting motor. 4. After the engine starts the booklet, release the key, the power supply of the starter is cut off, and the starting gear is separated from the flywheel under the action of the return spring to complete the starting action.

Just connect in series.
When the coil is de-energized, the electromagnetic suction force disappears, and the armature returns to its original position under the reaction force of the spring, so that the moving contact engages with the original static contact (normally closed contact). In this way, it is engaged and released, so as to achieve the purpose of conduction and cutting in the circuit.
Precautions for relay use:
In order to maintain the performance of the relay, be careful not to drop the relay or subject it to strong shocks. Relays after being dropped are recommended to be used no longer.
The relay is used as much as possible in an environment with room temperature and humidity, less dust and harmful gases. Harmful gases include sulfur, silicon, nitrogen oxide and other gases.
For magnetic latching relays, they are placed in the action or resetting position as needed before use, and for polarization relays, pay attention to the polarity of the coil voltage.

Because the main purpose of the application relay is to control the strong current with weak current, including low voltage to control high voltage, small current to control large current. The effect is achieved by controlling the power on and off of its own coil, so that its contacts are powered on and off. In layman's terms, it is to control the magnet to attract or not, and the magnet then controls the contact switch, so the connector of the relay includes the contact connector that controls the circuit and the connector that controls its coil.
The conductive circuits of the relay are connected together with the exposed non-live metal parts and shells, and can withstand the AC voltage of 2kV (RMS) and 50Hz for 1min test, and there is no insulation breakdown or flashover resistance.
An electromagnetic relay is a switch that uses an electromagnet to control the on/off of the working circuit. >>>More
The working principle of the electromagnetic relay is to use the electromagnetic effect to control the mechanical contact to achieve the purpose of on-off, to energize the coil with the iron core, generate a magnetic field for the coil current, and adsorb the armature with the magnetic field to act on and off the contact, and the whole process is a process of "small current, magnetic, mechanical and large current". >>>More
Other switches are controlled by means of an electromagnet.
The landlord's "mouth" is very powerful.
Depending on the classification method, there are the following types of relays that are commonly used. >>>More
