It is well known that corrosive gases, high humidity and strong oscillations are three important conditions that cause oxidation and frictional corrosion and lead to connector failure. These environmental factors can have a significant impact on tin and lead-tin contact surfaces, as is the case with 90% of connector surfaces. Usually, people use electroplated precious metals, such as gold plating or silver plating, because these metals do not oxidize. The thickness of these coatings varies from 0.5 μm to 1.27 μm. However, unfortunately, because of the high price of these precious metals and their processing, such electroplating processes are expensive, so people use such electroplating materials as little as possible. In automotive electrical harness applications, only about 10% of the connection points use this type of metal. As a result, some major connector suppliers, such as FCI, have other alternative plating solutions (such as pure tin plating, Tin-Teflon, NXT, and press-fit t...

When talking about the connector, it must be inseparable from the material of the connector. Different materials can bring different product performance. At the same time, the material of the connector can affect the price of the product, so understand the connector. Knowledge of material materials is necessary. The following  Konnra Electronics  engineers have compiled some of the materials of the connector materials. The following is a summary. Let's read them together. As shown in Figure 1, the connector insulator is commonly used Usually: PBT, nylon, ABS, PC, LCP and other materials are shown in Table 1, but in principle, materials with better flame resistance are used. A.PBT material: Generally used PBT material plus 20-30% glass fiber, with anti-cracking, anti-shock, anti-electricity, good wear resistance, low friction coefficient, good self-lubricating effect, good oil and chemical resistance. It has good dielectric strength under high temperature and high humidity. The...

Want to know the blind plug connector related products, we must first understand what its definition is, it is a kind of connector, for the average user may be a bit strange, then the definition of the blind plug connector What is it like? The following  Konnra Electroncis  engineers will tell you about the definition of blind plug connectors. The blind-plug connector adjusts itself to the correct connection position according to the self-contained guiding system, so it can be used in special operations where the power outlet is too far or too concealed to affect its visibility and difficult to touch to know its exact position. Specialties. These meticulously designed connectors are uniquely designed to ensure reliable, consistent precision docking, minimizing the risk of misconnections. The blind-inserted connector must also be of high quality and adaptable, so that it can maintain its durable and highly reliable characteristics even if it is hit and beaten during use. ...

        Users who often interact with FPC connectors are very knowledgeable about the structure of FPC connectors. What is the structure of the FPC connector? The following Konnra Electronics engineers will come to your FPC connector. The structural principle of this aspect.          Konnra Electronics  engineers pointed out that FPC connectors can be thinned, and to reduce the footprint of the connector, and to achieve a miniaturized, high-frequency signal transmission connector, the connector consists of four parts, respectively, the core, the tongue , terminals, soldering pieces, the following is the knowledge of these four parts;         1. The function of the FPC connector rubber core is to protect the terminal, insulation, guiding when connecting, providing the strength of the mechanism, etc. The manufacturing process of the FPC connector rubber core is generally using an injection molding process, and the ma...

With the rapid increase in sales of various types of handheld miniaturized electronic device products in the market, many electronic product manufacturers have greatly improved the demand for basic electronic device accessories such as plug-in connectors, and at the same time, for the production. The quality and stability of miniaturized high-performance electronic products, many electronic product manufacturers have put forward a lot of high-level technical requirements for the board connector. Then, when purchasing a stable and durable plug-in connector product, what are the main points of the product? First, pay attention to the manufacturer's production technology Although the quality-guaranteed plug-in connector product is a seemingly simple electronic accessory, in fact, it is necessary to meet the requirements of current electronic product manufacturers, and it also needs to overcome many technical difficulties. At present, some professional plug-in  connector manufacture...

In the connector industry, connectors are divided into three categories: wire to wire connectors, wire to board connectors, and board to board connectors depending on the properties of the connectors connected to the connectors. However in the day Often used, there is no absolute distinction. Many connectors can be used in two or even three cases. How do we distinguish between these connectors? Konnra Electronics specializes in the production of connector products. According to incomplete statistics in the industry, we can roughly distinguish as follows: What is a  wire to wire connector ? Wire to wire connectors are typically connectors that work between wires and cables or between cables and cables. What are the main  wire to  wire connectors? In the connector industry, there is also a product called a connecting wire, which is also known as a terminal wire, and one end has a terminal and the other end is...

When the size of electronic components is getting smaller and smaller, the circuit connection of different electronic component products needs to be more refined, and as the electronic industry users continue to improve the quality requirements of electronic products, the application of a wide variety of plug-in connectors Reliability is even more important for electronics industry customers. Below,  Konnra Electronics  explains why high-quality, durable and efficient plug-in connectors are well recognized by users in the electronics industry. First, in line with product miniaturization needs The electronic devices in modern society have become increasingly miniaturized. Due to the increasingly narrow space for installing electronic components, many electronic industry users are more demanding on the connector of the board. The well-received plug-in connectors in the market have been upgraded from board-to-board to side-plugged, which is more in line with the miniaturizatio...

Recently, in our mail, many users are asking for such a question - what should we pay attention to when making RJ45 connector? In order to facilitate the user's friend's review, Konnra Electronics has compiled this document to introduce the RJ45 connector production time. Some aspects to be aware of. I hope that with the introduction of Konnra Electronics, you can pay attention to what is a clearer standard for the production of RJ45 connectors. Every connector has its own point of view, and the RJ45 connector is no exception. In general, to make RJ45 connectors, we need to pay attention to the following aspects, as follows: 1. RJ45 connector trimming: Check whether the standard type of wire is accurate; the scale is not in compliance with the requirements; the cutting must be flush, not scratching the wires, the wires are not dirty, etc. 2. RJ45 connector peeling the skin: Check whether the stripping port is flush, not peeling the core wire, grouping wire, etc., and the pe...

To understand the usb interface, you must first understand its concept. In English, usb is the abbreviation of Universal Serial Bus, translated into Chinese is the meaning of "universal serial bus". It is not a new bus standard, but a new interface technology for PC applications. In 1995, the usb interface was already used on the PC, but due to the lack of software and hardware support, the USB ports of these PCs were idle. Until 1998, with Microsoft's built-in support module for USB interface in Windows 98, and the increasing number of USB devices, the USB interface gradually entered the practical stage. USB uses a 4-pin plug as a standard plug. With this standard plug, all peripherals can be connected in a daisy chain without losing bandwidth. The USB standard divides USB into five parts: controllers, controller drivers, USB chip drivers, USB devices, and client drivers for different USB devices. USB requires support from the host hardware, operating system, and p...
