Description
[technical field]
The utility model relates to a kind of radio frequency connector, relates in particular to the insulator of this radio frequency connector and the fit structure of outer conductor.
[background technology]
In the prior art, for radio frequency connector, usually insulator is fixed in the outer conductor with the roll riveting method or hangnail is set at the medial surface of outer conductor, the groove that cooperates with the hangnail of outer conductor is set on the insulator, hangnail and groove cooperatively interact and insulator are retained in the outer conductor, thereby prevent the insulator interior axial motion of body outside.In the prior art, though the roll riveting method can effectively prevent the axial motion of insulator in outer conductor, but its cost height does not meet the requirement that present product reduces cost.In addition, hangnail is set and the mode rebound amount at high temperature of groove is set on insulator at the medial surface of outer conductor big, thereby can cause secure fit to lose efficacy.
Therefore, be necessary existing technological improvement to overcome above-mentioned defective.
[utility model content]
Technical problem to be solved in the utility model provides a kind of radio frequency connector of being convenient to the position of stable center terminal and insulator.
For solving the problems of the technologies described above, the utility model provides a kind of radio frequency connector, but on surface soldered to an external equipment, it comprises outer conductor, is housed in the insulator in the outer conductor and is housed in the interior center terminal of insulator, outer conductor is provided with the installation portion that can be mounted to outer conductor, described installation portion is provided with the host cavity of accommodating insulator, described outer conductor is provided with hangnail at the terminal edge of the close external equipment of its host cavity, and described hangnail moves to the direction away from external equipment in order to prevent insulator.
Compared to prior art, the radio frequency connector of the utility model is provided with hangnail at the terminal edge of host cavity, and insulator supports and can prevent that on this hangnail insulator from moving simplicity of design in the axial direction, and be convenient to the position of stable insulation body, and then stablized the position of center terminal.
