Problems solved by technology

[0021] However, when adjusting the characteristic impedance value of the plug connector 101 described in Patent Document 1, it can only be adjusted from a high characteristic impedance value to a low impedance value, and it is necessary to further add other conventional connectors on the front end 103a side of the signal conductor 103. The electrostatic capacitance adjustment region 110 that does not need to be provided in the plug connector has a certain area after extending the length and width dimensions, which has the following problem: the amount of metal material used to form the signal conductor 103 increases. , resulting in an increase in product cost

Embodiment

[0132] Next, the plug connector of the present invention was trial-produced and evaluated, and the following description will be given.

[0133] The plug connectors shown in the examples are used in addition to Figure 7 In addition to the grounding conductors shown, there are figure 1 The structure shown is a plug connector for coaxial cables with a characteristic impedance of 50Ω, including a signal conductor made of a steel nickel-silicon (Corson) type copper alloy material, and a ground conductor made of a phosphor bronze material for springs. , The insulator made of LCP material, the distance d between the contact part of the signal conductor and the front end of the inner conductor of the coaxial cable is 0.85mm, and the depth dimension of the three concave parts is 0.04mm. The thickness is 0.1mm. The thickness dimension of the connector is 0.62mm. The width dimension of the connection part of the signal conductor is 0.4mm, the diameter of the inner conductor of the c...

Abstract

The present invention provides a coaxial connector, etc., which can be adjusted to improve VSWR and maintain the characteristic impedance of the coaxial cable, and can effectively achieve ultra-low profile. The coaxial connector (1) of the present invention has a signal conductor (3), a ground conductor (5) and an insulator (7), and is characterized in that the ground conductor (5) and the signal conductor (3) are arranged opposite to each other The two conductors opposing regions (13) of the two conductors form a distance expansion part (15), and the distance expansion part (15) makes the grounding conductor The vertical distance (X) between the inner surface (5a) of (5) and the back surface (3a) of the signal conductor (3) facing the inner surface (5a) is increased.

Description

technical field [0001] The present invention relates to a plug connector used for connecting a coaxial cable, especially a plug connector used for connecting an RF module and an antenna among internal parts of an electronic instrument. [0002] In addition, the present invention relates to a receptacle connector used in communication equipment such as smartphones and notebook computers, electric equipment, and electronic equipment. [0003] The present invention also relates to a coaxial connector composed of a plug connector and a receptacle connector, which does not cause an increase in substrate manufacturing cost and has a structure capable of stable connection even at a mating height of 0.8mm The ultra-low profile of the left and right sides does not cause mis-matching and mis-installation, and there is no short-circuit and other adverse conditions. Background technique [0004] For example, a conventional plug connector used in a high frequency band includes a contact...
