Harness processing three: crimping and soldering terminals

-
The manual soldering technique is to melt the solder at a certain temperature, and the molten solder is spread along the surface of the weld by capillary suction to form a wett of the solder and the weld, and the weld is firmly bonded to the core of the wire. Has good electrical conductivity. The crimping technology is to apply a certain pressure to two specific metal surfaces by a crimping tool or equipment at normal temperature, so that the metal joints can be properly plastically deformed to produce a reliable electrical connection, which has good mechanical strength and excellent Electrical performance and environmental resistance.
Harness processing three: crimping and soldering terminals
We also need to understand the terminals. The terminals are the main components for wire processing. There are many types of terminals. The crimp terminals need to use the open terminals, and the wires are placed on the terminals of the crimping parts from the side. Most of the welding terminals can be welded, but the working hours are large, the technical requirements are high, the efficiency is low, the inspection is difficult, and subjective factors are many.
After the terminal is crimped and welded, it must pass the tensile test. It cannot be pulled or broken within a certain range. If it breaks or falls off, we must check the crimping and welding faults before inspecting and repairing. This is also a factor that affects quality.

  SAE J1939 (hereinafter referred to as J1939) is the recommended standard of the American Society of Automotive Engineers (SAE). It is controlled and communicated by the "Truck and Bus Electrical & Electronics Committee" (Track & Bus Electrical & Electronics Committee). Developed and written by the Track & Bus Control and Communications Network Subcommittee. J1939 has become a recognized industry standard and choice for commercial vehicle diagnostics and data communication heavy, off-highway, truck, bus, ship propulsion, power generation, industrial pumping, construction, and material handling machinery. J1939 is a high-level protocol network (CAN) based on Controller Area. It is widely used by the diesel engine industry to provide diagnostic data such as vehicle engine speed, temperature, oil temperature, exhaust emissions, and other customizable options. J1939 connectors are divided into black and green rubber cores, but do you know the difference between t

Benefits of overmolded connectors and wiring harnesses?

What is overmolding? In short, overmolding is an injection molding process in which two or more materials are used to combine a harness wire and a connector to form a single part, and the cable assembly is placed in a mold. In this process, the first material substrate will be covered by other materials. The overmolding process requires the use of insert molding (single injection) or multiple injection molding techniques to cover rigid plastic parts with TPU layers or other overmolding materials. So what are the benefits of the connector and harness overmolding process? Benefits of overmolding connectors and harnesses: 1. Increase the flexibility of the cable harness exit so that most of the movement between the cable harness and the connector occurs at the cable harness exit. 2. Provide abrasion resistance, impact resistance or impact resistance. 3. Fix the cable assembly by sealing the assembly in plastic. 4. Provide 360 degree strain relief and increase tension. 5. Cr

In the context of global environmental conservation, new energy vehicles have become an inevitable trend in the development of automobiles worldwide. PwC's first blueprint for the Chinese auto industry, released on December 8, states that China's new energy vehicle sales are far ahead of other markets in the world. With the government's vigorous support for new energy vehicles, China's new energy vehicle era has arrived. Global sales of new energy vehicles reached 500,000 in 2015, of which 330,000 were sold in China, three times the previous year, and far ahead of other markets in the world. Accelerating development, Internet giants and other emerging players are actively entering the market, bringing pressure and shock to traditional car manufacturers and dealers. There is no doubt that new energy and intelligent connected cars have become the mainstream of the automotive industry, and the demand for applicable wiring harnesses will also increase significantly.
