How to choose and use the circular connector correctly? The circular connector is a relatively precise component, which can carry out the transmission of electric energy and signal transmission. Its reliability is directly related to the safety and reliability of the entire power system. It is not easy to choose and use circular connectors correctly. There are many manufacturers of such products. There are certain differences in the specifications, types, performance and uses of products produced by different manufacturers. We need to have a A general understanding, but also need to be connected to the technical standards of the product, and the current quality of the product. From the product manual provided by the manufacturer, we can understand the production standards of the selected product, as well as the product's size, weight, technical parameters, and installation methods. From this, we can analyze whether the product is reasonably designed and whether it is safe and reli

I've ever met a customer asking, what's the difference between a tattoo machine and a tattoo machine ? Many people think that it's the same tattoo. It's just because there are more needles and fewer needles. Some people even look for some "tattoo masters" who use eyebrow tattoo machines to work in pursuit of a low price. It was a cheap price, and I got a work that disappointed me or even failed. Today we will take a look at the difference between the two before. After comparing them, I believe that everyone will consider whether they are still attracted by the low prices before the next tattoo. 1. Different working principles: Eyebrow tattoo machine---The eyebrow tattoo machine adopts the working principle of the eccentric head driven by the motor. The horizontal transmission rod is rotated through the eccentric head of the motor shaft, and the transmission rod moves up and down to drive the needle bar to work up and down. Limited by the working limit of the m

If you happened to be working in an industrial unit or you are an operator of machinery, then you would realize the importance of a push button switch. Push button along with other switches is designed for the smooth functioning of commercial applications and industrial usage. It provides a multitude of benefits to the operators that are in charge of controlling the machinery. These buttons are basically designed to control some functions of a machine or a process. These switches are commonly used in simple manual operations. It is important to check the specifications of these switches in order to ensure compatibility with your devices. In order to facilitate smooth functioning, the surface of a push button switch is usually flattened so that it can be pressed or pushed easily. Various types of buttons and switches are used for commercial applications and industrial products.

With the maturity of technologies such as artificial intelligence, big data, and the Internet of Things, smart cities have set off a new wave of urban construction. According to relevant data, more than 600 cities in China are currently promoting the construction of smart cities. However, as smart city projects are in full swing, LED displays as smart city display terminals will also be seen everywhere, and with it is the increasingly serious "light pollution" problem. How should LED outdoor display related companies deal with it? ? The problem of light pollution in the LED display industry has a long history With the continuous advancement of the industrialization process, as early as the 1930s, the international astronomy community put forward the concept of light pollution, but light pollution has not been paid attention to until recent years. As a by-product of industrial civilization, light pollution sources include exterior and interior lighting of buildings, advertisi

We have heard more about water cooling and heat dissipation, and its application in industry is more and more. What are the benefits of water cooling? Ultra quiet. The liquid cooling cooling system uses the pump to circulate the coolant in the cooling pipe and dissipate heat. The heat absorbing part on the radiator is used to absorb heat from the heating core. The heat absorbed by the heat absorbing part is discharged to the outside of the main engine through the radiator designed on the back of the fuselage. In other words, the advantage of liquid cooling is that it can transfer heat to the radiator without increasing the temperature inside the fuselage, instead of using liquid to cool it. As long as it can improve the cooling performance of the heat conducted by the radiator discharging the heat pipe into the air, the silent design can be realized by reducing the fan speed of the cooling radiator or adopting fan less design. Heat dissipation is fast, water cooling also has a very imp

As manufacturers continue to improve the sliding door opener s, many different types of sliding door openers have gradually appeared in our eyes. Let's talk about the functions and compatibility of the sliding door openers . 1. Function With the improvement of residential intelligence and safety requirements, when choosing a sliding door opener, you must consider expanding the function. For example, whether the sliding door is convenient to use inductive access control and card reader to control, to restrict the entry of people without a card; whether the remote control device of the door opener can be easily compatible with other remote control equipment to realize multi-door joint control, etc. Some automatic door operators have this kind of function, which is easy to install, but some door operators do not have this function, and they must be equipped with many devices to install, thus leading to unnecessary expenses. 2. Compatibility Judging from the materials used in many plac

The so-called wire-to-board connector is the connector that connects the wires and the circuit board. The function of the connector is mainly to transmit power and signals. Therefore, the wire-to-board connector can be said to be the ancestor of all links, depending on various uses and requirements. , There are countless types of wire-to-board, but in the information industry, most of them are distinguished by the distance between the pins and the transmitted current and voltage. The biggest difference between a wire-to-board connector and a wire-to-wire connector is a wafer. The wire-to-board connector is welded to the circuit board by the socket connection wire, which plays a role of current flow. The structure of the wire-to-board connector is very simple: place the electrodes (contacts) in the shell (plastic shell). There are two types of contacts: stick or chip "plug" and "socket". Squeeze the plug completely into the socket and cover it to achieve "match

Although the development of the plastics industry in Thailand is limited, the investment in plastic equipment has reached more than 1 billion US dollars in the past 10 years, and the market prospect of plastic injection moulding machine is promising. In order to continuously produce various modern products, the Thai plastics industry must update its equipment and introduce advanced technology to compete with plastics manufacturers in other countries and regions. Nowadays, the Thai plastics industry can only provide general household plastic products, and it will continue to increase investment in the future. According to the Thai Plastics Corporation, the future investment in equipment for the Thai plastics industry will cost approximately US$2 billion. This shows that there are huge business opportunities in the plastic machinery market in Thailand. The chairman of the Thai Plastics Association said that there is currently no plastics company investing in modern high-quality plastics

COB(Chip On Board ) Technology Newer COB technology presents many advantages: wide viewing angle, solid dustproof, shockproof, and often waterproof surface which is rigid and prevents damage to LED elements. Flat and even face minimizes moire effect. There are a few manufacturers who are experimenting with this upcoming technology and some products are already available for purchase. Unfortunately there are also challenges associated with COB LED video screens that are yet to be resolved. Surface Mounted Device LED SMD LEDs are the more recent, resilient, efficient, and long lasting technology for mass production. SMD parts can be made smaller and thinner because the part is only soldered to the "surface" of one side of the circuit board. SMD screens usually use 3-in-1 LEDs. With one RGB 3-in1 LED unit per pixel, there are three tiny LED chips sealed inside a single part. Therefore, the color blends better, and the image is sharper. Dual In-Line Package (DIP) DIP LEDs contai

The wire-to-wire connector includes the form of wire-to-cable or cable-to-cable, and its defining feature is that two single-wire individuals or corresponding wires in two cables are permanently connected to each other. These permanent connections are more common in fixed connections, line-to-line connections and IDC connections. Connectors are classified into three basic types: wire-to-wire, wire-to-board and board-to-board. These three types of connections are not completely different. The following two reasons can explain this type of overlap. First of all, the design scheme of the same connector only needs to be redefined after a slight change in the connection method, which becomes a new design scheme applicable to another type of connection method; secondly, a cable is assembled during assembly You can install a wire-to-wire connector on one end and a wire-to-board connector on the other end. For example, the appearance of I/O connector level 5 products is the most common exampl

The popularity of eating chicken has led to competition in the game industry. Large and small companies are competing to join in and all want to get a share of the game. The author thinks that the popularity of "eating chicken" has both accidental and inevitable factors. Why is it inevitable? I think it should be seen from the development trend of hardware market. Recently, hardware manufacturers have made great efforts to improve the performance of CPU and graphics card, which has spawned a large wave of installation demand. Most of the purpose of the installation is to get a better game experience. As the "chicken eating" game requires high performance of hardware, hardware manufacturers seize this opportunity to vigorously promote their products to get a better "chicken eating" experience. The same recommendation from manufacturers and players leads to the feast of chicken eating. Although eating chicken is good, it also needs good hardware support. The

With the global energy shortage, solar energy has been vigorously developed as a new type of energy. Among them, solar batterys are the most used in our lives. Solar batterys are mainly based on semiconductor materials. Photoelectric materials are used to absorb light energy and then undergo photoelectric conversion to make it generate current. What is the working principle of solar battery ? In the past, from an electrical point of view, the silicon we used was all neutral. The excess electrons are neutralized by the excess protons in the phosphorus. The missing electrons (holes) are neutralized by the missing protons in boron. When holes and electrons are mixed at the junction of N-type silicon and P-type silicon, neutrality is destroyed. Will all free electrons fill all holes? will not. If so, then the whole preparation is meaningless. However, at the junction, they do mix to form a barrier, making it increasingly difficult for electrons on the N side to reach the P side. Eventually

We've all seen a LED wall or sign; actually, we see them daily. If you've ever been to the airport, a baseball game, or in your favorite store, you've encountered one, as they are everywhere. Digital signage is very versatile and can share a lot of information, both clearly and concisely. They can list information or entertain the viewer with graphics and short video clips. It is up to the venue owner how they utilize digital signage. One important aspect of digital signage is the pixel pitch. It is something the average viewer is never aware of, unless it's incorrect, as it then becomes noticeable. Pixel pitch matters in digital signage because it affects how well the viewer can see the display. What is Pixel Pitch? Pixel pitch is the density of the light-emitting diode (LED) clusters that make up the panel of a larger led display . The pixel pitch directly correlates with the resolution and clarity of the images being displayed. Also called pitch, or dot pitch, the pi

The purpose of a display wall in any control room is providing situational awareness and a useful common operating picture for multiple operators to simultaneously view relevant information and collaborate in critical decision‐making processes. Display systems in control rooms should be treated differently than display systems used in boardrooms, auditoriums, signage and short‐term viewing applications, because operators need to sit in front of the screens for longer hours monitoring critical information and handling incidents. The capability to interact efficiently with the display wall defines operational efficiency and alertness. If the custom led display size is not properly selected, the resulting strain on operator eyes can negatively affect operational efficiency. Your investment in the control room display system could be wasted. Screen size, resolution of the individual screens, the resulting optimal visual acuity, sill height (distance from floor to bottom of screens) and av

The LED industry always strives to innovate and to be better, faster, and brighter. With this constant search for new technology comes exceptional designs and breathtaking capabilities. In order to bridge the gap between state of the art custom LED panels and their internal components, how to get better & more pixels within LED panels? More Pixels Receiving cards are expected to have a higher and higher loading capacity, to provide the amount of pixels needed. With the design of cabinets trending more and more towards fine pixel pitch, the requirement for receiving cards to have a small size is more important than ever. Only if a receiving card has a high loading capacity and small size is it then able to meet the needs of clients, and keep costs low. Better Pixels LED display rental is a fast paced industry, and LED tiles need to always be as versatile as possible. The same LED panel may be used at a meeting room, a tradeshow booth, or even in front of a TV camera. With more viv

Versatile and recyclable die cut grey cardboard is the primary source of packaging in a host of different industries. What Is Die Cutting? Die cutting is a manufacturing process that uses a specialised tool or die fitted to a machine that presses the required shape from various chipboards. Preparing the die to turn a three-dimensional package into a two-dimensional flattened template relies on a great deal of skill and accuracy. Die cutting can create highly complex cardboard shapes and uses a process known as knifing to include apertures, tear strips and tamper-proof seals. Scored lines are incorporated to allow the black cardboard shape to be speedily folded into the finished carton. Die cut paperboard is used for thousands of packaging solutions. The food industry relies on die cutting to create paperboard sleeves for pre-prepared meals, cartons for cereals and decorative cardboard boxes for chocolates. Die cut apertures or windows in elaborate designs are frequently used to give

Laminated chipboard panels are a versatile form of chipboard cardboard that are used in many different industries. Here are answers to some of the Frequently Asked Questions that we are asked: What are Laminated Chipboard Panels? If something thicker than the maximum density of single-ply chipboard is required, then two or three pieces can be laminated together using PVA glue to produce a panel. This process ends up creating a very strong material. What Sizes are the Panels Available in? In terms of thickness, anything from 300micron (.3mm) up to 5000micron (5mm). As for width and height: a maximum of 2000mm x 3200mm. What can Laminated Chipboard Panels be used for? They have many uses, such as: Packaging. As on-line shopping for every conceivable product continues to grow, cheap packaging is becoming more and more important. Grey chipboard is ideal for this as it is light, has great strength, and can easily be moulded into different shapes and sizes of package. And, as it is made fr

1. Character placement is unreasonable   The character cover pad SMD soldering piece brings great inconvenience to the soldering of the component and the on-off test of the printed board.   The character design is too small, which makes screen printing difficult, and the over-construction causes characters to be stacked on each other, making it difficult to distinguish.   2. the processing industry can not clarify   The single-panel design is on the TOP layer. If it is not clarified, it will be done in reverse. The fabricated board is also lacking in good soldering.   For example, a four-layer PCB board design uses four layers of TOP mid1 and mid2 bottom, but the processing is not placed at the same time, which requires clarification.   3. Draw pads with padding   When designing the circuit, the pad can be traced by the DRC, but the processing is not possible, because such a pad can not directly generate solder resist data. When the solder resist is applied, the pad area will be a sol

Brush cutters, also known as grass brush cutter , is divided into electric power and internal combustion power through different powers. Internal combustion power is divided into two-stroke and four-stroke gasoline engines. Through different transmission methods, it is divided into flexible shaft transmission and straight rod transmission. It has a wide range of uses, which mainly used for landscaping, garden maintenance, road cleaning, forest fire prevention, crop harvesting, etc. The grass brush cutter is a two-stroke power, and attention should be paid to the power, transmission and cutting tools during use to ensure the normal use of the machine: 1. Engine The engine is a two-stroke engine. The fuel used is a mixture of gasoline and engine oil. The ratio of the mixed oil is: two-stroke special engine oil: gasoline=1:50. The gasoline should be above No. 90, and the engine oil should be two-stroke engine oil. The symbol is 2T. You must use brand-name engine oil, preferably special en

1. Eliminate the influence of injection molding machine and mold factors To choose an injection molding machine with a capacity equivalent to that of the injection molded product, if the injection molding machine has problems such as material dead ends, it is best to replace the equipment. For the mold casting system, exhaust grooves, etc., which can cause color difference, it can be solved by the maintenance mold of the corresponding part of the injection mold . The problems of injection molding machines and molds must be solved before the production can be organized to reduce the complexity of the problem. 2. Eliminate the influence of uneven mixing of color masterbatch and masterbatch Poor mixing of plastic masterbatch with color masterbatch will also make the product color volatile. After the masterbatch and the masterbatch are mixed uniformly, when they are fed into the hopper through the lower suction, the masterbatch is separated from the masterbatch due to the electrostatic e

The choice of heavy duty racks generally depends on the size, weight and type of the warehouse, and the purpose of the warehouse. It is made of cold rolled steel and can be stored in large warehouses and heavy goods in large warehouses. Although the storage density is relatively low, but the load-bearing weight is large, equipped with pallets and various accessories, it can also be used for mechanical storage, which can solve the problem of access to most commodities and is widely used in manufacturing, third-party logistics distribution centers, etc. In fact, heavy-duty racks have many advantages: the column is prefabricated, and the steel card is inserted between the beam and the column, and it is locked with a key to prevent it from falling off. Fully assembled structure, can be combined arbitrarily, easy to install and disassemble; each column has a 75mm adjustment hole, which can be adjusted according to the height of the goods, suitable for storing large or small amounts of good
