In the 1940s all terminals were soldered

1953 AMP introduces crimp barrel terminals

1960 Buchanan introduces 4-notch crimp tool with ratchet (Ref. MS3191)

1961 Boeing adopts Minuteman program’s ML-C-26500 standard

1963 MS3191-1 is released as the first crimp tool standard

In 1965 Daniels Manufacturing introduced the MS3191-4.

1969 MIL-T-22520 published and dated, superseding all previous specifications

1974 Changed to MlL-C-22520, added slash table

1996 Changed to MIL-DTL-22520

2016 to present Completed SAE AS22520 changes

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.

The automobile wiring harness runs throughout the entire car. It connects various electrical devices on the car and serves as a medium for power supply and signal transmission of each device. This article mainly introduces the components and functions of automobile wiring harnesses
1What is a wiring harness?
The automobile wiring harness is often compared to the car's neural network system. The automobile wiring harness is the network main body of the automobile circuit. Without the wiring harness, there would be no automobile circuit. The literal meaning of a wire harness is a bundle of wires. The automobile wire harness defines the environment in which the wire harness is used, that is, it is assembled on the car, as shown in the figure below: Figure: Vehicle wiring harness (red part)
The automobile wiring harness runs throughout the entire car. It connects various electrical devices on the car and serves as a medium for power supply and signal transmission of each device. The automobile wiring harness is often compared to the car's neural network system. The automobile wiring harness is the network main body of the automobile circuit. Without the wiring harness, there would be no automobile circuit.

2 Functions and functions of the wiring harness
The wiring harness is an indispensable system-level component in the vehicle. Its function is to provide and distribute power to various systems in the vehicle, and at the same time, it serves as a medium for signal transmission between various components.
To put it bluntly, if a car's electrical components, such as headlights, want to be powered by power, they need to be connected to the battery or generator through a wiring harness to form a power loop. In order for the headlights to light up, the body controller (BCM) must recognize the driver's intention to turn on the light combination switch. The signal interaction between the combination switch and the BCM also needs to pass through the wiring harness.
3 components of automobile wiring harness
The range of low-voltage wiring harness components is wide, including cables, connectors, terminals, fuse boxes, relays, fuses, plastic brackets, metal brackets, PVC insulation tubes, corrugated tubes, heat shrink tubes, sealing rings, rubber sleeves, tapes, Cable ties, protective covers, bolts, etc.
Automotive wiring harnesses are composed of wires, connectors, wire harness wrappings, wire harness fixings (buckles, rubber parts, wire harness brackets, etc.) and wire harness accessories.
electric wire
Wires are the main component of the wiring harness, often called wires. They are the main part of the wiring harness and their main function is to carry the current required by the load. The important parameter of a wire is its current-carrying capacity. The current-carrying capacity of a wire is affected by the wire diameter (the cross-sectional area of the wire conductor), the wire length, the resistivity of the conductor and the ambient temperature.
Connector
Connectors are also called connectors, CONNECTOR, or connectors. Connectors are indispensable components for connecting wire harnesses to other electrical equipment. They are divided into wire harness end connectors and electrical appliance end connectors.
We often hear about male connectors (referred to as male terminals) and female connectors (referred to as female terminals). The connector where the male terminal is located is called a male connector, and the connector where the female terminal is located is called a female connector. The ones on our wiring harness end are usually female connectors.
For wiring harnesses, connectors are relatively precise parts. In order to ensure the connection performance between the wiring harness assembly and electrical equipment, male and female connectors are generally required to be used in sets, that is, the same set of connectors from the same manufacturer is selected. This is important for the car. This is very important for parts and safety parts, such as airbags and ABS.
Connectors can be divided into two categories: waterproof and non-waterproof. At the beginning of the design, PIN pins of different widths are selected according to the current that each PIN pin needs to carry, and then a cavity is formed on the connector to accommodate different PIN pins, thereby forming a Housing that accommodates multiple PINs.
CPA, plastic shell secondary locking mechanism (ConnectorPositionAssurance). Its function is to ensure that the buckle of the primary locking mechanism will not be easily withdrawn after the plastic shell and electrical interface are assembled in place. Due to its special function, CPA must ensure worker operability and legibility when designing. This is CPA is required to be an independent organization on the plastic shell and must also have a special color mark.
Waterproof sealing ring: There are two types of waterproof sealing mechanisms, one is used for sealing between plastic cases, and the other is used for sealing terminal leads.
TPA, terminal secondary locking structure, TerminalPositionAssurance. Not all terminals require a secondary locking structure. VW requires that TPA should be used when the terminal width is less than 2.8mm (including 2.8). In order to ensure the convenience of installation by wire harness factory workers, the color of TPA must also be identifiable and must be used during assembly. It has a clear feel. In order to ensure that the TPA will not automatically enter the locking position when the plastic case is transported to the wiring harness factory, an anti-locking mechanism is necessary on the TPA.
2.5.3 Wire harness wrapping
The main function of wire harness wrapping is to protect the wiring harness. Depending on the material of the wrapping, the main types of wrapping include corrugated pipe, PVC tape, cloth tape, flannel tape, sponge tape and aluminum foil tape.
Due to different materials, the material properties of different wrappings are also inconsistent. Correspondingly, their application conditions and methods on the wire harness assembly are also inconsistent. The specific selection should be based on the specific use environment of the wire harness and its wear resistance, Heat resistance.
4 wire harness fixtures
Unlike other parts on other cars, the wiring harness is a flexible part. The wiring harness cannot be sent in a predetermined shape. Therefore, in order to constrain the layout path of the wiring harness on the entire vehicle, additional parts need to be added to fix the wiring harness. These additional parts The part is the wire harness fixture, which plays the role of fixing the wire harness and constraining the wire harness layout path.
Wire harness fixtures include: cable ties, buckles, rubber sheaths, wire harness brackets, etc. Depending on the installation environment of the wire harness, such as the wiring harness installation space, temperature requirements, waterproof requirements, the shape and shape of each wire harness fixture The materials are not consistent. Even so, the wire harness fixtures also show a trend of standardization, and they are also one of the components that is easier to implement in the selection of wire harness platforms.
5 wire harness accessories
Wire harness accessories refer to other smaller products on the wire harness assembly, such as product labels, fuse clips, etc. on the wire harness assembly.
