Protective effect of harness wire circuits on electrical appliances

Look for the shortest distance between the electrical connections and use the shortest wire. And install the connector on both ends of the wire. The wires are bundled into bundles, and different materials are used as the protective layer depending on the position of the wires. At the same time, fully consider the reliable grounding of electrical equipment. In addition, the wiring harness should be easy to assemble and disassemble and easy to maintain. It is mainly composed of controller, stepper, logic discriminator and sound and light alarm. Each part is composed of an integrated circuit and related electronic components, which are respectively soldered on their respective printed boards. Only one block is used for each test bench, and a few or a dozen blocks are used for the stepper board and the logic board, depending on the complexity of the harness assembly. The following is a brief introduction to the functions of each part.

Every other length should be fixed with a plastic or plastic tube clamp, and the connector on the frame that is easily stained with mud should be covered with plastic film. When the original harness is severely damaged, can no longer be used, and the new harness cannot be purchased, the car electrician must make a new harness in summer. There are many ways to duplicate the new harness, which is the same as the repair harness. The diagnostic system is the engine system for each job. The component performs fault self-diagnosis, which can inform the driver of the detected fault in the form of an indicator light or a code. The vehicle has a fault and needs to be repaired. The electrical function description and wire configuration of the needle position of the diagnostic tool pin and the harness connector are provided.

The automotive wiring harness process assisted design system is based on a software system developed for the platform. The inline process design is an important part of the wire harness design, and the resulting inline process card is an important document to guide wire harness production. Based on the inline representation and automatic layout algorithm, the software automatically completes all inline layouts and generates inline process cards. The four inline process card layouts that are automatically generated are displayed.

The in-vehicle equipment is mainly composed of a CPS receiver, a communication device and some sensors to determine its own position, collect vehicle information, report to the main control center, and sometimes execute the command center of the main control center according to the needs. The electronic harness is responsible for the vehicle and the main control. The communication link of the center is the nerve center of the entire vehicle dispatch monitoring network. Because in the bus system, the sensor has only two wires connected to the outside. These two wires are both signal wires and power wires. If the low voltage time is too long, more than the capacitor can provide the time to maintain the chip operation, which will result in the chip failing. normal work. This data is used in estimating the capacitance. It is the time interval between two frames, which indicates the time that the sensor capacitor is charged or the sensor is measured analogically when the sensor is switched to the external power supply mode after the data transfer is completed.

Each of the electronic harnesses is generally fixed to the vehicle body with a plastic cable tie, a fixing card, or the like. The sheaths that are butted between the bundles are generally collectively fastened with a tie. According to the direction and diameter of the electron beam in different areas, consider the sealing and protection of the wiring harness, determine the direction and fixing of the harness.

Line protection is to protect the wires and protect the circuit components. The protection devices mainly include fuses, circuit breakers and fusible wires. Engines and the like have a great influence on the performance and safety of the whole vehicle. In addition, electrical devices that are susceptible to interference from other electrical equipment must have a single fuse. Engine sensors, various types of alarm lights and external lighting, horns and other electrical components have a greater impact on vehicle performance and safety, but such electrical loads are not sensitive to mutual interference. Therefore, it is possible to combine one another according to the situation and use one fuse together. The system is developed for the wire harness test problem on the automobile production line. The application of the test system controls the consistency of the wire harness production, reduces the defective rate of the wire harness product, reduces the labor intensity of the wire harness test, and improves the accuracy of the wire harness test. The socket block is used for connecting the conduction detector and the tested harness, and is composed of a spring probe, a spring push pin, and a socket block. The left end of the spring probe is in contact with the terminal of the harness to be tested, and the right end is connected to the extension circuit of the continuity detector as an information channel between the harness and the continuity detector. The structure of the spring push pin is similar to that of the spring probe. It is placed on the connector. When the restriction of the lock wedge mating plug is removed, the push pin pushes the connector out.

Visual inspection is required before replacement. The new wiring harness model should be the same as the original model. The wire terminals and the wires are connected reliably. You can pull the connectors and wires to loosen or fall off. Compare the new harness with the original harness, such as the size of the harness, wire terminal fittings, wire color, etc. should be basically the same. For doubts, use a multimeter to test and confirm that the harness is intact before it can be replaced.
