Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a short circuit structure for a stripline type resonant component that shorts the center conductor of the stripline type resonant component to a ground electrode.

(Prior Art) Conventionally, as a short-circuit structure of the center conductor of a stripline type resonant component, for example, as shown in FIG.
Short-circuited end 3 of center conductor 3 formed on one main surface of
a and the ground electrode 4 formed on the other main surface of the dielectric plate 2.
A short-circuited with a short-circuiting electrode 5 made by printing and firing a conductive paste on the central conductor 3, or connecting the short-circuited end 3a of the center conductor 3 and the ground electrode 4 with each other with a short-circuit bar 6 made of copper, as shown in FIG. It is generally known that the circuit is short-circuited.

By the way, as shown in FIG. 2, the short-circuiting electrode 5 formed on the end surface 2a of the dielectric plate 2 short-circuits the short-circuit end 3a of the central conductor 3 and the earth electrode 4,
Failure to conduct electricity between the shorting electrode 5 and the center conductor 3 is likely to occur at the edge formed by the main surface where the center conductor 3 of the dielectric plate 2 is formed and the end surface 2a. 6 is required, and the installation is time-consuming.

(Purpose of the invention) The purpose of the invention is to easily and reliably short-circuit the center conductor of the stripline-type resonant component and the ground electrode by using a stripline-type resonant component that is easy to manufacture. An object of the present invention is to provide a short-circuit structure for a stripline type resonant component.

(Structure of the invention) Therefore, in the present invention, a stripline type resonant component is formed on a rectangular dielectric plate and one main surface of this dielectric plate. It consists of a center conductor reaching the edge and a ground electrode formed on another main surface opposite to the above-mentioned one main surface of the dielectric plate, and the stripline type resonant component is attached to a case or a mounting plate. This is a short-circuit structure of a stripline type resonant component in which the ground electrode is electrically connected to the case or the mounting plate, and the short-circuited end on one end of the center conductor is short-circuited to the ground electrode, and the case or the mounting plate is cut and raised. It comes into contact with one surface between the two main surfaces of the dielectric plate and reaches the short-circuited end of the center conductor from the case or mounting plate, and is electrically connected to this short-circuited end to ground the shorted end. At the same time, a short circuit portion for positioning the dielectric plate in a direction perpendicular to the one surface, and a short circuit portion for positioning the dielectric plate by contacting two side surfaces adjacent to the one surface of the dielectric plate, respectively. It is characterized by having a positioning protrusion formed by cutting and raising the case or mounting plate.

(Embodiments) Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1a and 1b, a stripline type resonant component 14 has a ground electrode 12 and a center conductor 13 formed on both opposing main surfaces of a rectangular dielectric plate 11, respectively.
is conductively bonded to the inner wall of the metal case 15 with a conductive adhesive (not shown).

On the other hand, in the case 15, a shorting piece 15a having a substantially constant width is cut and raised on the end face 11a of the dielectric plate 11, which includes the shorting end 13a of the center conductor 13 of the stripline type resonant component 14. The tip of this shorting piece 15a and the shorting end 13a of the center conductor 13 of the stripline type resonant component 14 are connected to the solder 1.
6 is soldered.

Preferably, the case 15 is also formed with positioning protrusions 15b, 15b that protrude from both sides of the stripline resonant component 14, respectively, in order to determine the mounting position of the stripline resonant component 14.

In the above manner, by soldering the shorting piece 15a cut out from the case 15 to the shorting end 13a of the center conductor 13 of the stripline type resonant component 14, the shorting end 13a of the center conductor 13 and the ground electrode 12 can be easily and reliably short-circuited. Further, the shorting piece 15a is connected to the positioning protrusion 1
Together with 5b and 15b, it also functions for positioning the stripline type resonant component 14 with respect to the case 15, so that the stripline type resonant component 14 can be attached to the case 15 accurately.

In addition, in the above embodiment, the shorting piece 15a is
It is not limited to being cut out from the case 15, but may be formed by any method as long as it is formed so as to protrude from a part of the case 15.
Instead of the case 15, a mounting plate or the like provided inside the case may be used.

Furthermore, a conductive adhesive may be used instead of the solder 16 to connect the short-circuit end 13a of the center conductor 13 of the stripline type resonant component 14 and the short-circuit piece 15a.

Furthermore, the ground electrode 12 of the stripline type resonant component 14 and the case 15 can be bonded together by soldering.

(Effects of the invention) As is clear from the detailed description above, the present invention provides shorting pieces and positioning protrusions on the case or mounting plate to which the stripline type resonant component with the center conductor open at both ends is mounted. The short-circuited end of the center conductor of the stripline type resonant component is short-circuited to the ground electrode, so the stripline type can be easily manufactured because the center conductor is open at both ends without using any special parts. By attaching the resonant component to a case or a mounting plate, the short-circuited end of its center conductor and the ground electrode can be easily and reliably short-circuited.
