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

Abstract

The present invention provides a coaxial connector and the like which can be adjusted such that the VSWR is improved and the characteristic impedance of a coaxial cable is maintained, and effectively achieves a great reduction in height. This coaxial connector (1) is characterized by being provided with a signal conductor (3), a ground conductor (5), and an insulator (7), and in that in a both-conductor-opposed region (13) in which the ground conductor (5) and the signal conductor (3) are disposed opposing each other, a distance enlargement part (15) in which the vertical distance (X) between the inner surface (5a) of the ground conductor (5) and the back surface (3a) of the signal conductor (3), which is the surface facing the inner surface (5a), becomes larger without increasing the thickness dimension (t) of the coaxial connector (1) is formed.

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...
