Take you back to the history of terminal crimping

Electrical conductors have been used to transmit signals throughout aircraft since the dawn of flight and early propulsion systems. As air travel evolves, so do the requirements for the wiring harnesses and connectors used in these systems.

With the rapid progress in automobiles, aerospace, medical equipment, industrial equipment and other fields, the requirements for electrical systems are becoming higher and higher. The increasing number of electrical components and functions integrated into modern devices has resulted in a significant increase in the number and type of wires and cables in wiring harnesses. This complex wiring requires connectors, terminals, wires, fiber optics and other technology that requires precision tools.

Crimping: Then and Now

The first multi-pin connectors were terminated by soldering conductors to non-removable terminals. However, high temperature applications and the need for simple and reliable field service led to the introduction of connectors with removable terminals. They are crimped to the conductors rather than soldered.

The first standard crimping tools for crimping these new terminals were introduced in the early sixties. MS3191-1 is a military drawing that defines the tool and its accessories.

The MS3191-1 features a four-indentation crimp pattern and a positive stop positioner that controls indenter travel (crimp depth).

The MS3191-1 design is a compromise between operational simplicity and crimp performance because the crimp depth of any given terminal cannot be adjusted to accommodate the different diameters of the conductors being crimped. However, it fits the crimp connectors of that era. An improved tool design with independently adjustable crimp depth was soon introduced as the MS3191-4.

The MS3191-4 features internal adjustments that are completely independent of the positioner, allowing selection of seven independent crimp depths, allowing for optimal crimping of conductors ranging from AWG 12 to 26, regardless of the contact’s barrel size . MS3191-4 also introduces the use of a dual-ended indenter to produce eight indentation crimp patterns that consistently achieve superior tensile break values and mechanical properties.

The MS3191-4 introduces the concept of a turret head containing three positioners that can be used without the need to separate any one of the positioners from the base crimp tool.

In 1969, military specifications for two crimping tools were developed to replace existing military drawings. They are MIL-T-22520C (Navy) and MIL-T-83724 (U.S. Air Force), which define standard size crimp tools similar to MS3191-4, but with an expanded eight-step crimp depth range. These specifications also define a micro crimp tool for crimping conductors as small as AWG 32. The two documents were merged into MIL-C-22520D in 1971. All previous military standards for crimp tools, including MS3191, were subsequently cancelled. This list includes specifications for notch crimp tools, terminal lug crimp tools, air tools, coaxial cable crimp tools, and other specialty crimp tools.

MIL-DTL-22520 establishes a single specification that defines the performance requirements for all crimp tools used on military-standard electrical connectors. This eliminates the waste and confusion caused by the overlapping application of many different "standard" crimping tools due to numerous unrelated military drawings.

Crimp concept

As an electrical connection method, crimping is widely used in the electronics and electrical industries. It tightly combines the metal barrel with the conductor through pressure, ensuring that the terminal or contact end can be firmly connected to the electrical conductor.

To achieve a satisfactory crimp, the selection and combination of conductors, crimp barrels and tools are critical. Conductors need to have good electrical conductivity and mechanical strength to withstand the electrical current and mechanical stress during operation. The crimping barrel needs to have sufficient elasticity and plasticity so that it can be tightly combined with the conductor under pressure to form a strong connection.

When correctly matched tools are used, the joints created have good electrical and mechanical properties. The tool will meet these requirements consistently and reliably, ensuring repeatability with quality cycle control tools.

The resistance of a properly designed and controlled crimp connector should be equal to or less than that of wire of equal cross-section. Specifications specify requirements for millivolt voltage drop at specified currents.

The mechanical strength of a crimp joint and its pullout force (tensile strength) varies with the applied deformation (i.e., the crimp die of the tool determines the crimp configuration and deformation). Therefore, by properly shaping the deformation, high pullout forces can be obtained. The die in the tool determines the complete crimp configuration, which is often an element of the contact and/or connector design.

Some design considerations include:

a) contact type, its size, shape, material and function,

b) the type and size of wires to be accommodated,

c) The type of tool that must be configured.

800V system challenge Charging pile of charging system

background:

With the gradual launch and popularization of vehicles equipped with 800V system platforms, a series of new challenges in 800V voltage systems compared with traditional 400V voltages are gradually attracting attention. This article will do some analysis and comparison from different systems of the entire vehicle. When we mention 800V now, many people will think of "800V fast charging", "silicon carbide electric drive", etc. What we need to understand is that 800V fast charging or overcharging is just a system in the 800V high-voltage platform. We can divide the charging facility end to the vehicle end into: charging system, battery system, drive electronic control system, auxiliary unit system, etc. The 800V platform requires these dispersed systems to work under the same voltage platform.

800V charging "Basic principles of charging"

640 (1).png

This article mainly talks about some preliminary requirements for 800V charging piles. Let’s first look at the charging principle: when the charging gun head is connected to the vehicle, the charging pile will provide ① low-voltage auxiliary DC power to the vehicle to activate the built-in BMS of the electric vehicle ( Battery management system), after activation, ② Connect the vehicle terminal to the pile terminal, exchange basic charging parameters such as the maximum charging demand power of the vehicle terminal and the maximum output power of the pile terminal. After the two parties match correctly, the BMS (battery management system) of the vehicle terminal will The charging pile sends power demand information, and the charging pile will adjust its output voltage and current based on this information, and officially start charging the vehicle. This is the basic principle of charging connection, and we need to be familiar with it first.

800V charging: “Increase voltage or current”

640 (2).png

Theoretically, if we want to provide charging power and shorten charging time, there are usually two ways: either you increase the battery or increase the voltage; according to W=Pt, if the charging power is doubled, the charging time will naturally be halved; according to P =UI, if the voltage or current is doubled, the charging power can be doubled. This has been mentioned repeatedly and is considered common sense.If the current is larger, there will be two problems. The larger the current, the larger and heavier the cable required to carry the current will be. This will increase the wire diameter and weight, increase the cost, and make it inconvenient for personnel to work; in addition, according to Q=I²Rt, if The higher the current, the greater the power loss. The loss is reflected in the form of heat, which also increases the pressure on thermal management. Therefore, there is no doubt that it is not advisable to increase the charging power by continuously increasing the current, whether it is charging or driving. Internal drive systems are not advisable.

Compared with high-current fast charging, high-voltage fast charging generates less heat and lower losses. At present, almost mainstream car companies have adopted the route of increasing the voltage. In the case of high-voltage fast charging, theoretically the charging time can be shortened by 50%. The increase in voltage can also easily increase the charging power from 120KW to 480KW.

800V charging: "Thermal effects corresponding to voltage and current"

640 (3).png

But whether you are increasing the voltage or the current, first of all, as your charging power increases, your heat will appear, but the heat manifestations of increasing the voltage and increasing the current are different, and the faster one will have a greater impact on the battery. A larger one, a relatively slower one but with more obvious thermal concealment and a more obvious upper limit. But the former is preferable.

Since current encounters lower resistance as it passes through the conductor, increasing the voltage reduces the required cable size and dissipates less heat. While increasing the current, the current-carrying cross-sectional area increases resulting in larger outer diameter cables. It is heavier, and the heat will gradually increase as the charging time increases, making it more concealed. This method has greater risks for the battery.
