Therefore, the movable terminal not only undertakes the task of electrical contact with the fixed terminal, but also undertakes the task of providing the restoring force required to return to the contact state between the two when it is disconnected from the fixed terminal. When the structure is miniaturized, there will be Due to the short elastic arm of the movable terminal, it is easy to undergo plastic deformation, resulting in insufficient elasticity, which leads to the failure of the switch
Therefore, in the prior art, it is difficult to achieve both the improvement of the durability of the movable terminal and the miniaturization of the coaxial connector.

Embodiment Construction
[0022]The present invention will be described in detail below in conjunction with the drawings and embodiments.
[0023]SeeFigure 1 to Figure 4, Is a coaxial connector 100 according to the present invention, which is used to be fixed to a circuit board (not shown). The coaxial connector 100 includes a body 11 and a housing module stacked and held up and down with the body 11 12 and corresponding fixed terminals 13 and movable terminals 14 fixed between the main body 11 and the housing module 12. The fixed terminal 13 and the movable terminal 14 are respectively assembled at positions close to both sides of the main body 11. The movable terminal 14 is corresponding to the fixed terminal 13 elastically butted. The coaxial connector 100 can be used for soldering to the internal circuit substrates of various electronic devices. The switch function between the movable terminal 14 and the fixed terminal 13 can realize the free conversion between the internal antenna and the external antenna,...

The invention discloses a coaxial connector which is provided with a butt joint hole for an external probe to be inserted. The coaxial connector comprises a body, a shell module, a fixed terminal anda movable terminal, wherein the fixed terminal and the movable terminal are correspondingly assembled in the body and / or the shell module, and the fixed terminal comprises a fixed terminal contact part; the movable terminal comprises a movable terminal substrate, a movable terminal contact part formed by extending one side of the movable terminal substrate, a movable terminal elastic arm formed byextending the other side of the movable terminal substrate, and a movable terminal butt joint pin formed by bending and extending the extending tail end of the movable terminal elastic arm; the movable terminal contact part is used for being in butt joint with the fixed terminal contact part, the movable terminal elastic arm can achieve elastic deformation in the plugging direction of an externalprobe, and the movable terminal further comprises two movable terminal connecting arms which extend towards the two sides from the two side edges of the movable terminal substrate respectively; the extending tail ends of the two movable terminal connecting arms are connected with movable terminal function arms, and the two extending tail ends of the movable terminal function arms abut against thebody.
Description
Technical field[0001]The present invention relates to a coaxial connector, in particular to a coaxial connector having a fixed terminal and a movable terminal that are in contact with or separated from each other.Background technique[0002]In today's increasingly miniaturized electronic information field, such as mobile phones, tablet devices, wireless local area network devices and other devices, it is usually necessary to realize the free conversion of internal antennas and external antennas through the switch function of coaxial connectors. In addition, the coaxial connector is often installed in a circuit board, and is used to connect an external test head to the circuit board for testing the high-frequency characteristics of the circuit board. As the appearance of electronic information equipment becomes smaller and smaller, the demand for such coaxial connectors is becoming more and more widely used. As we all know, the smaller the shape, the more difficult it is to realize the...
