The car connection line runs through the entire car. It connects various electrical equipment on the car and serves as a medium for equipment power supply and signal transmission. This article mainly introduces the components and functions of the car connection line. It is often compared to the car neural network system. Car connection The wire is the network main body of the automobile circuit. It connects various electrical appliances on the automobile and serves as the power supply and signal transmission medium for the equipment. Car connecting wires are often compared to car neural network systems, which are the network main body of automobile circuits. There is no car circuit without connecting wires. So, let’s briefly talk about the functional composition and role of car connecting wires!

The functions and functions of car connecting cables

The automobile connecting cable is an indispensable system-level component of the entire vehicle. It distributes power to various systems of the entire vehicle and serves as a medium for signal transmission between components. In short, in order to get the power to light up, the car's electrical appliances (such as headlights) need to be connected to the battery or generator via wires to form a power circuit. In order for the headlights to light up, the body controller (BCM) must be aware of the driver's intention and turn on the light combination switch. The signal exchange between the combination switch and the BCM must also pass through the wiring harness.

Components of automobile connecting lines

Low-voltage wiring harness components include cables, connectors, terminals, fuse boxes, relays, fuses, plastic brackets, metal brackets, PVC insulating tubes, corrugated tubes, heat shrinkable tubes, fillers, rubber sleeves, automotive wiring harnesses, etc. It consists of wire harness packaging, wire harness fixings (fasteners, rubber, wire harness brackets, etc.) and wire harness accessories.

The main component of the automobile connecting wire, usually called the wire, is the main part of the wiring harness, and its main function is the current required by the load. An important parameter of a conductor is its current-carrying capacity. The current-carrying capacity of a conductor is affected by the wire diameter (cross-sectional area of the conductor), wire length, conductor resistivity and ambient temperature.

  Connector

Connectors are also called connectors or connectors. Connectors are an indispensable component when connecting a wire harness to other electrical equipment. They are divided into wire harness side connectors and electrical equipment side connectors. We often hear about male connectors (male terminals and female connectors). The connector with male terminals is called a male connector, and the connector with female terminals is called a female connector. What's on one side of our harness is usually a female connector. In wire harnesses, connectors are relatively precise parts. In order to ensure the connection performance between the wire harness assembly and electrical equipment, male and female connectors are generally required to be used in sets. In other words, it is very important to choose the same connector from the same manufacturer for important components and safety components of the car, such as airbags and ABS. Connectors are roughly divided into two types: waterproof and non-waterproof. At the beginning of the design, PIN pins of different widths are selected according to the magnitude of the current that should be carried on each PIN pin, and cavities are formed on the connector to accommodate different PIN pins, thereby forming a Housing that accommodates multiple PINs.

Its function is to ensure that after the plastic shell and electrical connector are assembled intact, the fasteners of the primary locking mechanism will not be easily disengaged. Due to the particularity of its functions, CPA must ensure operator operability and visibility when designing. Therefore, the CPA must be a separate mechanism on the plastic housing and also require a special color display.

Waterproof gasket: There are two types of waterproof sealing mechanisms, one is used for sealing between plastic shells and the other is used for sealing terminal leads.

Car connecting wire fixation

Car connecting cables are different from other parts of other cars. Car connecting cables are flexible parts and samples of car connecting cables cannot be sent in the default form. Therefore, additional components need to be added for fixation. The shape and material of the fixation vary depending on the installation environment of the wire harness, such as the installation space of the wire harness, temperature requirements, waterproof requirements, etc. However, the wire harness fixation still shows a trend of standardization and is One of the easy components for wiring harness platform selection.
