Upgrading of car sound systems

Posted On:2018-06-08 10:33:35

Car stereo is a kind of component that electronic engineers often touch. The role of the car audio wire harness is very simple: to build a bridge of communication between blocked circuits or isolated circuits, so that the current can flow and the circuit can achieve predetermined functions. The form and structure of car connectors are ever-changing. They are mainly composed of four basic structural components: contact parts, shells(depending on the variety), insulators, and accessories.
With the increase of automotive functions and the universal application of electronic control technology, there will be more and more connector plugs and electrical parts, and more and more wires. The number of circuits and power consumption on the car will increase significantly, and the wire bundles will become thicker and heavier. This is a big problem that needs to be solved. How to make a large number of wire bundles in the limited car space more effective and reasonable arrangement, so that the car wire bundles play a greater function, has become a problem facing the automotive manufacturing industry.
Before arranging the wire bundles, the wire beam diagram must be drawn in advance. The wire beam diagram is different from the circuit diagram. The schematic diagram of the motorcycle wiring circuit is an image that describes the relationship between various electrical parts. It does not reflect how the electrical parts connect with each other, and is not affected by the size of the various electrical components and the distance between them. Motorcycle wire bundles and wire bundles must take into account the size of each electrical component and the distance between them, and also reflect how the electrical parts are connected to each other.
After the technicians of the wire beam factory made the wire beam alignment plate according to the wire beam diagram, the workers cut the line alignment according to the rules of the wiring plate. The main line of the vehicle is generally divided into engines(ignition, electric spraying, power generation, starting), instruments, lighting, air conditioning, auxiliary appliances, etc., with main line bundles and branch lines.
A whole main line bundle has multiple branch lines, just like tree poles and branches. The main line of the vehicle is often centered on the dashboard and extends backwards and forwards. Due to length or assembly convenience, Some car wire bundles are divided into front wire bundles(including instrument, engine, front light assembly, air conditioning, battery), rear wire bundles(taillight assembly, card light, luggage box lights), and top top wire bundles(doors, top lights, sound speakers) and so on.
Each end of the wire beam will be marked with marked numbers and letters to indicate the connection object of the wire. The car audio beam operator sees that the sign can be correctly connected to the corresponding wire and electrical device.
