[Problem that the idea aims to solve]

However, the conventional dielectric element connecting device described above does not connect the internal conductor and the pattern. In addition, the connection between the pin and the internal conductor and the pin and the pattern must be soldered. This is due to For this reason, work efficiency is poor and dielectric damage due to uneven bending of the pins. Misalignment of the dielectric element is likely to occur, and if misalignment occurs, the dielectric element may become misaligned. Because the heat capacity is large and it is difficult to correct misalignment, and the conductor material is silver, it is difficult to The rice fields are difficult to remove and cannot be reused. Also, since it uses a wiring board, it does not take up much space. There were problems such as the space being large.

[0005] In view of these circumstances, the present invention not only has good workability, but also eliminates positional shift and occupies less space. The present invention aims to provide a dielectric element connecting device with an extremely small space.

[0006]

[Means to solve the problem]

The present invention has a crown part formed of a springy material and fitted onto the outer surface of the end of the connecting dielectric element. and a conduction terminal having a pointed head that fits into the hollow end of the dielectric element to be connected. A dielectric element is connected to a dielectric element through a connecting terminal. .

[0007]

[Effect]

The dielectric element is connected by fitting a conductive terminal into the dielectric element. The outer conductor of one dielectric element is connected to the other inner conductor, and the inner conductor of one dielectric element is connected to the other inner conductor. Each is connected to the other external conductor.

[0008]

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0009] FIG. 1 shows conduction terminals 5, which form a pair to form a dielectric element connection device. Configure.

0010 The conduction terminal 5 is made of a material that is a good conductor and has spring properties, such as phosphor bronze or beryllium. The crown part 6 is made of aluminum copper and fits on the outer peripheral surface of the dielectric element 2, and the hollow part of the dielectric element 2 The crown part 6 and the pointed part 7 are connected in a stepped manner. 8.

[0011] The crown portion 6 is a flat plate formed into a cylindrical shape, and has an inner diameter larger than the outer diameter of the dielectric element 2. The diameter is slightly small, and when the crown part 6 is fitted to the dielectric element 2, the spring property of the crown part 6 It is designed so that a required contact pressure can be obtained between the outer peripheral surface of the dielectric element 2 and the outer peripheral surface of the dielectric element 2.

0012 The pointed head 7 is a flat plate that is folded back at the tip and shaped into an arrowhead shape. Like the crown part 6, it has spring properties in the radial direction, and the pointed part 7 is connected to the hollow part of the dielectric element 2. The required contact pressure is obtained between the inner surface of the hollow part and the inner surface of the hollow part in the state of being inserted into the inner surface of the hollow part.

[0013] Next, the operation of this embodiment will be explained with reference to FIGS. 2 and 3.

[0014] Insert conductive terminals 5a and 5b into the ends of dielectric elements 2a and 2b to be connected, respectively. Furthermore, the pointed portions 7a, 7b of the conduction terminals 5a, 5b are connected to the dielectric element 2 on the other side. Fit into the hollow parts of a and 2b.

[0015] Fitting of the pointed parts 7a and 7b into the hollow part and the dielectric element 2 of the crown parts 6a and 6b Fitting into the ends a and 2b is also restricted by the step of the connecting portion 8, respectively. However The outer conductor of one dielectric element 2a is connected to the other dielectric element 2 via the conduction terminal 5a. b, and the inner conductor of one dielectric element 2a is connected to the other conductive terminal 5. b to the outer conductor of the other dielectric element 2b. Furthermore, the connecting portion 8 Due to the stepped shape, a gap 9 is formed between the dielectric elements 2a and 2b, and the conduction terminal 5a and 5b never come into contact.

[0016] As mentioned above, the work of connecting the dielectric elements 2 involves simply connecting the dielectric elements 2. It is only necessary to fit the conductive terminal 5 into the end, which is very simple. Furthermore, the dielectric element 2 For removal, it is sufficient to simply pull out the conduction terminal 5.

[0017] In addition, in order to make the connection between the dielectric element 2 and the conduction terminal 5 more secure, soldering is performed auxiliary. Of course, bonding may be performed using a conductive adhesive.

[0018] Furthermore, as mentioned above, both the crown part 6 and the pointed part 7 of the conduction terminal 5 have spring properties. Therefore, even if there are variations in the outer diameter and inner diameter of the dielectric element 2, connection can be performed without any problem.

[0019]

[Effect of the idea]

As described above, the present invention exhibits the following excellent effects.

[0020] Eliminates the need for a circuit board to connect dielectric elements and also eliminates the need for connection pins. The number of parts is reduced.

[0021] Connection work is extremely simple, and workability is improved by eliminating soldering. Significant improvements have been made, and together with a reduction in the number of parts, costs and manufacturing time have been reduced. It will be done.

[0022] The occupied space can be reduced to approximately the volume of the dielectric element.

[0023] Let the length of the dielectric element be the length of the greatest common divisor of each frequency of the expected model. This makes it possible to manufacture dielectric resonators by simply increasing or decreasing the number of connections. .
