For example, when the host of an electronic device (e.g., a desktop computer, a server, a car computer, etc.) is bulky or the installation location is complicated or hidden, most workers in the field will adopt the design structure of the strip line connector to utilize the length of the strip line connector to ensure that another electronic product can be electrically connected to the electronic device, or to enable the connector of the electronic device to be conveniently connected to a circuit board to transmit signals or power. However, since the conventional strip line connector usually only has the butt-joint surface to form a connection with another connector, if the user applies improper force or the plugging direction is deviated during the plugging process (especially in the blind plugging situation), the insulating body or the housing of the strip line connector or the other connector is easily deformed and damaged. In addition, with the demand for higher transmission speed and smaller size of the connector, the cable connector is likely to interfere with other electronic components at a short distance during high-speed transmission. Therefore, how to effectively solve the above problems is a major subject of the present invention discussed herein.
