Figure 31 means the figure that makes coaxial plug 1700a with epitaxy part 1705 and the chimeric state of coaxial connector 1100, and Figure 31 (a) is overall diagram, and Figure 31 (b) is near the amplification view coaxial connector 1100.Figure 32 means the figure that makes coaxial plug 1700b with epitaxy part and the chimeric state of coaxial connector 1100, and Figure 32 (a) is overall diagram, and Figure 32 (b) is near the amplification view coaxial connector 1100.
In order to measure the characteristic of antenna etc., connecting plate 1400 is disconnected with switching spring 1500 TURPs, and with in connecting plate 1400 and situation that the center conductor of coaxial plug is electrically connected to, the leading section of use center conductor has larger-diameter the first coaxial plug 1700a.As shown in Figure 31 (b), the fore-end of coaxial plug 1700a have lower end position from epitaxy part 1705 outstanding towards below in the form of a ring and cross section be step-like projection 1703.Projection 1703 is located at the position in the hole 1407 of passing connecting plate 1400, but the diameter of the outer peripheral portion of projection 1703 is larger than the diameter in hole 1407, and forms epitaxy part 1705.In addition, projection 1703 and the insulant 1601a, the 1601b butt that switch on spring 1500.Due to the thickness that has insulant, therefore, center conductor 1701a forms the structure that with the contact site 1509 of switching spring 1500, does not contact.In addition, when coaxial plug 1700a inserted, the extension 1705 of center conductor 1701a contacted with the contact site 1408 of connecting plate 1400.In addition, coaxial plug is become can make external conductor 1702a, 1702b displacement on above-below direction together with pin insulator by elastic bearing with respect to the main body of plug, and center conductor is also become displacement independently by elastic bearing.
In order to measure the characteristic of high-frequency circuit etc., connecting plate 1400 is disconnected with switching spring 1500 TURPs, and will switch in spring 1500 and situation that the center conductor of coaxial plug is electrically connected to, use the leading section of center conductor to have the second coaxial plug 1700b of the diameter less than the diameter of the first coaxial plug 1700a.The diameter of the leading section of the center conductor 1701b of the second coaxial plug 1700b is less than the diameter in the hole of connecting plate 1,400 1407, can pass hole 1407.In addition, the leading section of center conductor 1701b and contact site 1509 butts that switch spring 1500.In addition, the annexation of antenna and high-frequency circuit also can be opposite.
When coaxial plug 1700a, 1700b are not installed, contact site (the 4th contact site) 1504 of switching spring 1500 is pressed into the contact site (the 3rd contact site) 1402 of connecting plate 1400 by the elastic force of elastic portion 1503, make connecting plate 1400 and switching spring 1500 keep the state that is electrically connected to.
When the first coaxial plug 1700a with epitaxy part 1705 was installed, the bottom of the external conductor 1702a of the first coaxial plug 1700a and external conductor 1300 butts, the leading section of the center conductor 1701a of coaxial plug were inserted logical vertical hole 1203.Under this state, the projection 1703 of the fore-end of the center conductor 1701a of coaxial plug 1700a and insulant 1601 butts of elastic portion 1503.At this moment, the elastic force of the center conductor of coaxial plug is larger than the elastic force of elastic portion 1503, and therefore, elastic portion 1503 is pressed down and strain by the center conductor of coaxial plug, contact site 1504 separates from contact site 1402, so that connecting plate 1400 is disconnected with switching spring 1500 TURPs.In addition, meanwhile, contact site (the first contact site) 1408 butts of the epitaxy part 1705 of the leading section of the center conductor of coaxial plug and the outer rim in the hole 1407 of the extension 1404 of connecting plate 1400, so that the center conductor of coaxial plug is connected the state that is in connection with connecting plate.By this, the signal that flows from connecting plate 1400 towards switching spring 1500 is flowed, so that antenna is checked by the center conductor of connecting plate 1400 towards coaxial plug.
It is comparatively desirable position relationship that the position relationship of the second contact site 1509, the 4th contact site 1504 and insulant 1601 is in for the 3rd contact site 1402 and being connected of the 4th contact site 1504 are cut off.Namely, there is the 4th contact site 1504 in free end side at the switching spring 1500 of cantilever beam shape, insulant 1601 and position than this contact site be more by the position butt of base portion side, and therefore, the addendum modification of the 4th contact site 1504 that is positioned at free end side is larger than the addendum modification of the part of butt.
When the second coaxial plug 1700b of the less center conductor of diameter with leading section is installed, the bottom of the external conductor 1702b of the second coaxial plug 1700b and external conductor 1300 butts, the leading section of the center conductor 1702b of coaxial plug are inserted logical vertical hole 1203.Under this state, the center conductor 1702b of coaxial plug and the contact site of elastic portion 1503 (the second contact site) 1509 butts.At this moment, the elastic force of the center conductor of coaxial plug is larger than the elastic force of elastic portion 1503, therefore, elastic portion 1503 is pressed down and strain by the center conductor of coaxial plug, contact site 1504 separates from contact site 1402, so that connecting plate 1400 is disconnected with switching spring 1500 TURPs, meanwhile, the center conductor of coaxial plug is in switching spring 1500 state that is connected.By this, 1400 signals that flow from switching spring 1500 towards connecting plate are flowed, so that high-frequency circuit is checked by the center conductor of switching spring 1500 towards coaxial plug.
