  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.
