How to Crimp Wires With Insulated Terminal

Crimping is a style of joining wires to metal fittings that are then used to connect the wire to another wiring component or to other wires.

The fittings themselves come in various styles, and are collectively known as “crimp connectors.”

They are most commonly used with stranded wires found in the wiring of appliances, electronics, or automobile systems.

The technique involves compressing a small insulated metal sleeve on the end of the connector around the exposed bare wires.

Wire connections using crimp connectors are often used in locations where the heat of soldering is not appropriate, or where the wire connection may need to be detached occasionally.

Connections made with crimp connectors take up little space; they also are easier to make than solder connections and when done properly, they can be just as effective.

When you crimp a connector onto the end of a wire, the idea is to form a tight, continuous electrical union between the wire and the connector fitting that will stay together permanently.

To achieve this, both the connector sleeve and the wire both have to be malleable enough to deform under a compressive force.

An electrical connector is a device for joining electrical circuits together using a mechanical assembly.

The connection may be temporary or serve as a permanent electrical joint between two wires.

There are hundreds of types of electrical connectors.

Connectors may join two lengths of wire together or connect a wire to an electrical terminal.

Crimp connectors work best with stranded wire because solid wire usually isn’t malleable or ductile enough to make a reliable connection.

The wire gauge isn’t a major factor.

You can crimp a connector onto beefy 8-gauge wire as effectively as you can onto 18-gauge wire, as long as you use a connector of the right size.

Below area few connector types.

On the far, upper left, we have an insulated splice connector to connect two wire ends together.

To the right, the forked connector (spade, or split ring) is useful for connecting wire to screw terminals by sliding the fork into a screw terminals’s socket.

Screws can be partially screwed in before installing the terminal.

The ring terminals in the middle are also useful for connecting wire to screw terminals.

While the ring terminal provides a more reliable connection, you would need to completely remove the screw before installing the terminal.

On the far, upper right we have a male spade connector (blade).

These can slide into the female spade connector (double crimp) that is shown on the bottom right.

Depending on the design and application, these connectors can come in different flavors like flanged fork or locking ring terminal.

To achieve the necessary compressive force, it’s best to use a crimping tool when attaching crimp connectors to a wire.

Pliers or a hammer will work in a pinch, but using such tools can result in a loose connection that ultimately results in an open circuit.

Nothing is more difficult to diagnose than a loose crimp connection in complex automotive and appliance electrical systems, where crimping is most commonly used.

Choose the Right Connector

Crimp connectors come in many styles, so make sure you choose the right one for the application.

  • ring connector makes the most secure connection to a terminal post. It can be disconnected only if nut on the terminal is removed.
  • spade connector is best for situations in which it’s impractical to remove the nut from the connection terminal. The spade-shaped tip slides into a socket on the terminal.
  • quick-disconnect connector can be barrel-shaped or blade-shaped. You can separate the connection by pulling the two halves apart.
  • butt connector permanently splices two wires together.

How To Make Heat Shrinkable Intermediate Joint

How to make heat-shrinkable intermediate joint and the production process of heat-shrinkable tube.

In today’s society, heat shrinkable casing is widely used in electronics, power, cable and other fields as well as daily life plays an important role in social development. 

Heat shrinkable casing is an alloy of radiation crosslinking polyolefin and its polymer, which produces shape memory effect after high-energy ray radiation, so as to realize the coating of various wires and cable joints and the purpose of insulation protection. 

So what are the manufacturing processes of heat shrinkable casing? 

It is mainly divided into four parts: the first mixing granulation, the second extrusion molding, the third radiation crosslinking, the fourth expansion shaping, packaging.

The production process of heat shrinkable sleeve has the following three points:

There is a chemical formula.

Molding technology (extrusion molding technology, injection molding technology).

Transmission control technology, tension control technology, expansion production technology and other production technology that requires accurate calculation.

The manufacturing process of heat shrinkable sleeve has the following four points:

Expansion to finalize the design

 

Heat the plastic pipe after radiation crosslinking to the high elastic state, and then use the expander to expand to get the heat shrinkable sleeve.

The process parameters of expansion finalize the design are: temperature 120~150℃, input speed 8~10Hz, pull out speed 8~10Hz, vacuum degree -0.06MPa.

Extrusion molding

 

Extrusion molding is by extruder, cooling water tank, tractor, tension machine and winding machine to complete. 

Its technological parameters are: extrusion speed of 20~50r/min, traction speed of 30~50 Hz, extruder temperature of 90~130℃.

Mixing granulation

 

Weigh all raw materials according to the formula and use a high-speed blender to stir them evenly, with a stirring volume of 110kg and a stirring time of 8-12min. 

Mixing and granulating are accomplished by pelleting machine, cooling water tank, blow drying machine and granulating machine. 

The mixing and granulation process parameters are as follows: the main engine speed is 1 000~1 400r/min, the feeder speed is 50~80r/min, the body temperature is 110~160℃, the head temperature is 190~240℃.

Radiation crosslinking

 

The function of the electron accelerator is to generate rays and irradiate the plastic pipe so as to produce crosslinking.

The function of the beam transmission device is to continuously send the plastic pipe into and out of the electron accelerator.

After the winding times are determined,  the desired radiation dose can be obtained by controlling the speed of the electron accelerator beam and the transmission device.  

These production processes can greatly reduce the investment cost of heat shrinkable casing, reduce energy consumption and enterprise production costs, improve production efficiency and product quality, and produce products with relatively high mechanical strength and long service life, corrosion resistance, aging resistance, environmental pressure and other advantages.

What Is The Realization Of Industrial Automatic Equipment Positioning

With the rapid development of the processing industry, the level of automation equipment in all walks of life is getting higher and higher.

Modern processing workshops are often equipped with automatic machine to improve production efficiency and replace workers in dangerous and arduous labor in harsh environments.

 

At present, the control methods of industrial automatic machine commonly used on the market are mainly driven by hydraulic or pneumatic pressure.

The advantage of this control strategy is that the structure is simple and the system is easy to control.

However, the disadvantage is that the positioning of the system is achieved by setting the position of the proximity switch, and the positioning accuracy is low.

Once the user requests to change the type of retrieving work, the positioning switch of each hydraulic or pneumatic cylinder must be re-adjusted to adapt to the new work task, Conducive to the automation of the production process.

 

The main motion of the automatic machine adopts the all-electric control mode.

 

The system uses the AC motor as the driving source, the dedicated AC motor servo controller is the lower position machine, the industrial control computer is the upper computer, and the system adopts the distributed control control strategy.

The design scheme has high control precision, high control real-time performance, compact structure and easy operation by the user.

What Is The Most Important Thing About Non-standard Automation Design

Theory is the direction indicator to guide practice.

In practice, the theoretical effect is not achieved because the details in the actual situation are not consistent with the theory, so it is very important to do every detail;

it is not denied that some theoretical basis is not perfect, resulting in Unexpected errors, so it is important to improve the theoretical knowledge reserve.

 

OF week Industrial Control Network: What is the most important non-standard automation design?

 

Q: Where are the difficulties in non-standard automation design?

 

A: The plan.

Only by understanding the product characteristics and product processing technology can a feasible and reliable implementation plan be proposed.

Only under the guidance of the blueprint drawn by the designer can the project be implemented in an orderly manner and achieve the final result.

 

Q: What is the most important non-standard automation design?

 

A: Nothing is not important.

The large-scale design is as small as a screw that is not tight, and every factor that affects the final acceptance is important.

 

Q: Which one is better for dead positioning and adjustable mechanisms?

 

A: The position that can be dead is determined to be dead, and it needs to be positioned and positioned.

The error will be concentrated, the adjustable mechanism will be reduced as much as possible, and the multiple adjustments of the equipment can be adjusted to achieve the final debugging effect.

The adjustment mechanism is fine and fine. .

 

Q: What issues are you paying attention to in mechanical design?

 

answer:

First, positioning.

 

1, The positioning of the processing object is related to the determination of the big blueprint and solves the customer’s demand problem;

 

2, The docking position between the single machine and the single machine determines the reliability of the connection production;

 

3, The positioning of the components in the stand-alone device determines the matching between the functional modules;

 

4, The positioning of the part in the component determines the certainty of the action of the mechanism;

 

5, Clear positioning and locking concepts, to prevent less positioning, to avoid over positioning;

 

6, Positioning solves the problem of functionality, meeting the functional requirements is the premise of the design;

Types and Differences of Cutting Machine

The choice of pipe cutting machine can be viewed from the following aspects:

一:Depending on the material to be cut, shape (round tube, square tube, bar, or special shape), dimensions and thickness of materials, cut straight or diagonally 45 degrees to choose different size models.

 

Different types of pipe cutting machines can process different sizes of materials;

Different materials require different power of pipe cutting machine;

The same pipe cutting machine, its 45 degrees of cutting material size is often smaller than 90 degrees of cutting;

Generally speaking, for relatively small iron pipe, copper pipe, in the cutting accuracy is not high, blanking output is not large can choose manual type or low-power semi-automatic pipe cutting machine.

 

二: According to the blanking accuracy requirements or quality requirements to determine.

 

If the blanking accuracy requirement is high, the output is large, the specification of the cutting material is large or thick, then we need to consider the automatic pipe cutting machine or the high-power semi-automatic pipe cutting machine.

Generally speaking, manual pipe cutting machine, semi-automatic pipe cutting machine and automatic pipe cutting machine all have the following characteristics:

(1) Manual cutting machine: feeding, clamping and cutting are manual operation, mainly for some cutting requirements are not high, the efficiency is not high, and the cutting amount is not large occasions.

(2) Semi-automatic pipe cutting machine: manual feeding, clamping and cutting are all automated operations, mainly for some occasions with high efficiency requirements, low length accuracy requirements and large cutting quantity.

(3) Automatic pipe cutting machine: feeding, clamping, cutting are automatic operation, mainly for some high efficiency requirements, there are certain cutting precision requirements, and the cutting amount is also large occasions.  

 

In the selection of pipe cutting machine, taking into account the above factors, I believe you can choose a suitable pipe cutting machine for your product.  

The Root Cause Of Automatic Machine Must Be Used

Foreign media reported that China’s manufacturing industry will be transformed from labor-intensive to capital-intensive.

In 2016, the number of automatic machine installed in China will rank first in the world.

Factors such as industrial transformation, robot density, and employment attitudes of young people are the main reasons for this change.

 

After swallowing up a lot of global manufacturing jobs, China will now hand over these jobs to robots.

China has become the world’s largest industrial robot market.

In 2014, sales of automatic machine in China increased by 54% year-on-year, indicating that China is accelerating the popularity of industrial robots.

According to statistics from the International Federation of Robotics, the number of automatic machine installed in China will be the highest in the world in 2016.

 

China is expected to become an automation center, a phenomenon that denies many ideas about robots and the global economy.

Economists often believe that automation is designed to reduce labor costs, and it can spawn advanced economies that protect manufacturing from threats of moving overseas and may even return manufacturing.

The motivation for universal automation has not disappeared.

However, in developing countries, robots will gradually replace jobs, and potential employment opportunities in Asia, Africa and Latin America’s frontier markets are decreasing.

 

In China, the support for economic strength has lagged behind the trend.

Labor costs have risen sharply, while countries with advanced economies such as the United States have been less affected.

At first, China relied on the labor cost advantage to bring a lot of manufacturing jobs, but new trends have destroyed this economic system.

The new robotics technology is cheaper and easier to use than ever.

In addition, many of the fastest growing Chinese manufacturing industries, such as automotive manufacturing, tend to rely on automation technology wherever the plant is located.

Some manufacturing jobs can only use robots, such as the precision work of electronics factories.

 

In fact, whether using robots made in China or robots from Western companies, China’s rapid popularization of industrial robots is also related to self-esteem.

Steven Wyatt, head of marketing and sales at ABB Robotics, a robot manufacturer, said: “When Chinese export goods, they are often hindered by product quality.

Now they will say, ‘We use robots with Western European and North American companies.

The same ‘.’ This is one of the reasons why the Chinese government is promoting this change.

In 2013, the Chinese government announced that by 2020, China will have at least three internationally competitive robotics companies, 8 to 10 supporting industrial clusters, and domestic robots in high-end robots will account for about 45% of the market share, and the robot density will reach 100 or more.

Some analysts believe that this top-down strategy will produce a “herd effect” that will result in wrong spending. Gan Jie, a professor at Cheung Kong Graduate School of Business and a director of Dajiang, said: “If you invest money in the wrong company, you will crowd out the most innovative companies.”

 

From the current point of view, robots do not seem to have much impact on the Chinese job market.

In 2014, the average wage in China’s cities increased by more than 10%, but this year China still plans to create at least 10 million new jobs.

Chinese business owners believe that it is increasingly difficult for them to find young people who are willing to work on boring assembly lines, which is the main reason they use robots.

Some electronics manufacturers say they have to deal with a turnover rate of up to 20% per month.

Although some factories have moved out of China, the employment environment in China is still in good shape.

Perhaps other developing countries have a better understanding of this.

The Inevitable Element Of The Rise Of Stamping Molds

Once upon a time, in the Pearl River Delta region, where the manufacturing industry was concentrated, the migrant workers from the south became competing to become a “screw” on the production line in the factory.

The same process was repeated day after day, and the robot was becoming a new booster for transformation and upgrading.

First, in the Pearl River Delta, the home appliance industry took the lead in “machine substitution”, the electronic information industry closely followed, the automobile, textile and garment industries are also ready to go, one by one “unmanned factory replaced the workshop where the workers were sweating” Factory building.

 

Molds production lines and automated production not only help enterprises to alleviate the shortage of skilled workers, cope with rising labor costs, but also better meet the standardization requirements of modern production, create greater production capacity, and help solve the land facing China.

Environmental carrying capacity and other issues.

The stamping molds can replace the person in a dangerous or uncomfortable working environment, complete the consistency and repeatability of the work cycle, can not be reached by humans, the stamping molds can be programmed, after completing the current task, can be executed by editing and installing the required tools.

A completely different task, the controller is connected to other molds systems to achieve molds integration.

 

At present, the stamping molds technology and industry are developing rapidly and are increasingly used in production.

It has become an important high-level automation equipment in modern manufacturing.
