Conventional miniature coaxial connectors typically include a female connector soldered to the circuit board and a male connector H for mating with the female connector. In the two connectors, the insulated body is sealed by a metal casing and the conductive terminals housed in the body, and then the metal casing is connected to a reference potential (usually referred to as a ground potential) to reduce the connector from being externally transmitted during signal transmission. The impact of electromagnetic interference. Typically, the method is to provide a ground point in the connector with the metal housing in contact with the ground point that forms a ground path with the external ground element to connect the metal housing to the reference potential. Therefore, if the metal casing is in poor contact with the grounding point, the grounding performance is greatly reduced. When the male connector is mated with the female connector, since the metal outer casing of the female connector and the metal outer casing of the male connector are not directly fixed, only the upper and lower bonding contacts of the two are in contact with each other, and the contact is extremely unstable, thereby causing the mother Connection| § The ground connection of the metal casing of both the male connector and the male connector is unstable, and the grounding performance is lowered. It is difficult to prevent interference from external electromagnetic waves, thereby affecting the signal transmission performance of the micro coaxial connector. Moreover, the female connector of the micro coaxial connector is soldered to the external circuit board only through the conductive terminals therein, and the female connector and the external circuit board are used after the male connector is repeatedly inserted and removed for the female connector. The connection may be loose, affecting the signal transmission quality of the product. 3 M384447 [New Content] The purpose of this creation is to provide a miniature coaxial connector with a simple structure, stable connection with an external circuit board, reliable electrical connection, good grounding performance and electromagnetic prevention. interference.

The accommodating body has a body portion and an extending arm extending from both sides of the body portion. The body portion is provided with an accommodating space, and a receiving groove for accommodating the conductive terminal is formed in the accommodating space. The conductive terminal has a soldering end connected to the external circuit board, and the soldering end protrudes outside the receiving space. The cover housing includes a tongue portion, an arm portion extending from the tongue portion, and a welded portion connected to the external circuit board. The tongue portion is covered and fixed on the body portion of the housing body, and the arm portion is wrapped on the extension arm and the arm portion The bonding surface is matched with the shielding shell of the male connector, and the bonding surface is provided with a first grounding bump. As described above, the female connector of the present miniature coaxial connector is connected to the external circuit board through the conductive terminal on the one hand, and the soldering portion covering the housing is connected to the external circuit board on the other hand, so that the female connector and the circuit board are firmly connected. It maintains a stable electrical connection when subjected to the insertion and removal force of the male connector. In addition, a first grounding bump is disposed on the arm portion of the covering body, and when the male connector is inserted into the female connector, the arm portion is in close contact with the shielding housing, and the first grounding bump on the two causes two The contact is more stable, which improves the grounding performance of the female connector and the male connector, thereby better preventing electromagnetic interference. 4 M384447 [Embodiment] In order to explain the technical contents, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description with reference to the drawings.
