2. Description of the Related Art FIG. 4 shows a conventional dielectric device connection device.

[0003] A conventional dielectric element connecting device for connecting a dielectric element having a hollow shape and a conductor between the hollow inner wall and the outer side is a conductor. The wiring board 1 is provided with a plurality of patterns 3 each including a land portion to which the dielectric element 2 itself is fixed and a lead portion, the same number as the number of dielectric elements to be connected. The dielectric element 2 itself is fixed to the land portion, and the outer conductor of the dielectric element 2 and the pattern 3 are electrically connected by soldering.
Are connected by soldering, and the pins 4 are connected to adjacent patterns 3 by soldering. Thus, the inner conductor and the outer conductor of adjacent dielectric elements 2 are connected.

However, the above-mentioned conventional dielectric element connecting device requires pins for connecting the internal conductor and the pattern, and furthermore, the connection between the pin and the internal conductor and the connection between the pin and the pattern are performed by soldering. is there. For this reason, the workability is poor, and the displacement of the dielectric element due to the unevenness of the pins is apt to occur. Further, when the displacement occurs, the heat capacity of the dielectric element is large and it is difficult to correct the displacement. Since the conductor is made of silver, it is difficult to remove the solder and cannot be reused. In addition, there is a problem that the occupied space is large because a wiring board is used.

The present invention has been made in view of the above circumstances, and has as its object to provide a dielectric element connection device which has good workability, has no positional displacement, and occupies a very small space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a conduction terminal 5.
Form a pair to form a dielectric element connection device.

The conductive terminal 5 is made of a material having good electrical conductivity and spring properties, for example, phosphor bronze or beryllium copper, and has a crown 6 fitted on the outer peripheral surface of the dielectric element 2 and a hollow section of the dielectric element 2. The crown 6 and the pointed head 7 are connected by a connecting part 8 formed in a stepped shape.

The crown 6 is formed by forming a flat plate into a cylindrical shape, and has an inner diameter slightly smaller than the outer diameter of the dielectric element 2. When the crown 6 is fitted to the dielectric element 2, the crown is formed. The required contact pressure between the outer peripheral surface of the dielectric element 2 and the required contact pressure is obtained by the resiliency of the portion 6.

The pointed head 7 is formed by bending a flat plate at the tip end and forming it in the shape of an arrowhead. The pointed head 7 has spring properties in the radial direction similarly to the crown part 6. A required contact pressure is obtained between the element 2 and the inner surface of the hollow portion while being fitted into the hollow portion.

Next, the operation of this embodiment will be described with reference to FIGS.

Conductive terminals 5a and 5b are fitted into the ends of the dielectric elements 2a and 2b to be connected, respectively, and the cusps 7a and 7b of the conductive terminals 5a and 5b are connected to the dielectric elements 2a and 2b on the other side. 2b.

The fitting of the cusps 7a, 7b into the hollow portions and the fitting of the crowns 6a, 6b to the ends of the dielectric elements 2a, 2b are also regulated by the step of the connecting portion 8.
Thus, the outer conductor of one dielectric element 2a is a conductive terminal 5a.
Is connected to the inner conductor of the other dielectric element 2b through
The inner conductor of the other dielectric element 2a is connected to another conductive terminal 5b.
Is connected to the outer conductor of the other dielectric element 2b.
Further, the dielectric element 2
A gap 9 is formed between the conductive terminals 5a and 5b, and the conductive terminals 5a and 5b do not come into contact with each other.

As described above, the work of connecting the dielectric element 2 is very simple, simply by fitting the conductive terminal 5 to the end of the dielectric element 2. Further, when removing the dielectric element 2, it is only necessary to remove the conductive terminal 5.

Incidentally, in order to more reliably connect the dielectric element 2 and the conductive terminal 5, it is needless to say that auxiliary soldering and bonding with a conductive adhesive may be performed.

Further, as described above, the crown portion 6 of the conductive terminal 5,
Since the pointed head 7 also has a spring property, even if the outer diameter and the inner diameter of the dielectric element 2 vary, the connection can be performed without any trouble.

[0019]

According to the present invention, as described above, the following excellent effects are exhibited.

A circuit board for connecting the dielectric element is not required, and no connection pin is required, so that the number of components is reduced.

The connection work is remarkably simple, workability such as elimination of soldering is remarkably improved, and a reduction in the number of components, a reduction in cost, and a reduction in the production period can be achieved.

The occupied space can be reduced to approximately the volume of the dielectric element.

By setting the length of the dielectric element to the length of the greatest common divisor of each frequency of the assumed model, it is possible to cope with the production of a dielectric resonator simply by increasing or decreasing the number of connections.
