  In many applications, screw-on RF connections can sometimes appear stretched and even unusable: for example, panels, daughter cards or inserts with multiple RF connection points. In these cases, the spacing between the connectors must be set very small, so that the nut cannot be accommodated; or the card/combination sometimes cannot be operated due to the need to be inserted into the slot. For these reasons, people have developed push-in connectors, also known as blind-mate connectors. The common blind-mate connector in military, aerospace, satellite communications and radar fields is the Blind-mate A/BMA (Blind-mate A/BMA) connector developed in the 1980s. In the initial period, the registered trademark used by BMA connectors was OSP, so it is often called OSP connector. The advantage of the BMA connector is that even if there is a slight degree of misalignment, mating can be easily achieved by pressing the plug into the socket with sufficient pressure, and then the internal mec...

Although the CLD (Car Light detection) board end is simple, it uses two 100μF 25V capacitors to make the product performance more stable. And this time directly upgrade to gold-plated pin header and 3.0mm connector. As we all know, 3.0mm wire-to-board connectors appear the most frequently in the use of automotive connectors, and the lights and central control account for a relatively large proportion. The main reason is the stability and shock resistance of 3.0mm with buckle connector products. The main functions of the gold-plated pin header are low impedance, fast transmission speed and strong wear-resistant life, which are much stronger than the tin-plated nickel-plated pin header. Main products:  1.27mm pin header  and  3.0mm DIP with buckle connector .

Speaking of the pin header, as a component practitioner, how much do you know? Do you know what effect the plating of the pin headers has? The following  Konnra Electronics  engineers will introduce you to the role of the pin plating. I hope that through our explanation, you will have a deeper understanding of the plating effect of the row of pins. The optimization of electrical performance can be considered from the control of the film on the surface of the contact plating that is already present and about to be formed. A major requirement for the electrical performance of the pin headers is to establish and maintain a stable pin header impedance. To achieve this, a metal contact interface is required to provide such inherent stability. Establishing such a contact interface requires that the surface film be able to avoid or split during contact engagement. These two different options clarify the difference between precious metals or rare metals and ordinary metals. To vary...

About the concept and classification of the Female header connector How much do you know, the electric bee optimization engineer pointed out that the Female header is a type of connector, commonly known as the Female header connector. Because in most cases it is used with the "pin header connector", the role and scope of the Female header connector is basically the same as that of the header connector. According to Konnra Electronics , the Female header connector is widely used on PCB boards in electronics, electrical appliances, and instrumentation products. Its role is to function as a bridge before being blocked or isolated in the circuit. The task of current or signal transmission. It is generally used in conjunction with the pin header connector to form a board-to-board connection, or used in conjunction with an electronic harness to form a board-to-wire connection, or it can be used independently for board-to-board connection. Classification: 1, Female header accordi...
