For example, in microwave coaxial equipment, a microwave coaxial connector is used to connect the input end or output end of a microwave coaxial line, and has a great influence on the characteristics of the microwave line. Therefore, it is necessary for the microwave coaxial connector to satisfy the microwave line characteristics, ie, VSWR (voltage standing wave ratio) and loss, to predetermined values. FIG. 6 shows an example.

It is formed. The center conductors P2 and J2 are each
It is positioned and fixed at the center of the coaxial section by insulators P3 and J3.

In the microwave coaxial connector described above, the center conductors P2 and J2 are fixed by the insulators P3 and J3, so as shown in Fig. 7, the microwave coaxial devices A and B can be connected simultaneously at two or more places. When doing this, it is not possible to absorb the pitch tolerance ±Δl,
Cannot be connected directly. Therefore, as an alternative connection means, as shown in FIGS. 8a and 8b, the front pitch tolerance ±Δl is absorbed by the coaxial cable C for connection. However, this method has the problem that the VSWR deteriorates as the number of connection points of the microwave line increases, and the loss increases as the length of the microwave line increases. In addition, the cost is increased due to the need for a coaxial cable, and the connection space is increased, and the connection workability is poor.

It is desired to improve coaxial connectors that can make connections at two or more locations at the same time.

That is, in the present invention, at least one of the two center conductors that are mated with each other is made flexible so that it can bend in the radial direction, thereby absorbing the pitch tolerance that occurs between two or more connectors. I try to do that. By the way, when the centers of the center conductor and the outer conductor constituting the coaxial section coincide, the coupling capacitance thereof is usually uniform radially. In contrast, when the center conductor is slightly eccentric, the uniformity of its coupling capacitance is disrupted, but the inventors' experiments have confirmed that this does not have a large effect on the overall impedance. For example, in a microwave band SMA connector, in order to set the impedance to 50 ohms, the ratio of the diameter of the center conductor to the inner diameter of the outer conductor is approximately 1:2.3, and if the diameter of the center conductor is 1 mm, then the outer The inner diameter of the conductor is
2.3mm, and the allowable eccentricity is about 0.2mm.
In this way, when the center conductor of an SMA connector with a diameter of 1 mm is eccentric by about 0.2 mm, it can be used up to the quasi-millimeter wave band.

It is provided with a cantilever support structure with P5 as the free end. In addition, in order to regulate the deflection of the center conductor P2 within the allowable stress range, the outer diameter of the mating part P4 of the external conductor P1 on the plug P side and the hole diameter of the mating part J4 of the external conductor J1 on the jack J side are Provides clearance for deflection.
