Abstract

PURPOSE:To ensure the electric conductivity between a prescribed part of electronic parts and a case by spreading a clipping part for electronic parts for a prescribed interval or over by the electronic parts. CONSTITUTION:A box type case 10 is formed by a resin having the elasticity, e.g. Nylon. Further, a couple of clipping parts 13, 14 clipping each dielectric coaxial resonator 1 are formed at each dielectric coaxial resonator 1 to a wall 12 opposed to the cover. Both the clipping parts 13, 14 are spread into an interval L2 larger than a prescribed interval L1 by the pressing force from a peripheral face 16 of the dielectric coaxial resonator 1. Then the conductivity between the outer conductor 10 and the plating electrode film provided to the case 10 is kept always by the elastic force of the clipping parts.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a housing structure for electronic components such as dielectric coaxial resonators.

(Prior Art) Some electronic components, such as dielectric coaxial resonators, are housed in parallel arrangement between predetermined opposing wall surfaces in a case.

FIG. 3 is a perspective view of a housing structure showing a state in which a plurality of dielectric coaxial resonators l are housed in a metal case 2. FIG. In this case, the top cover of the case 2 is not shown. A plurality of dielectric coaxial resonators l shown in FIG. 3 are housed so as to constitute a filter device, and are arranged in parallel in the longitudinal direction of the case 2. Each dielectric coaxial resonator l has the same shape, and has electrode films (inner conductor 4 and outer conductor 5) on the inner and outer circumferential surfaces of the cylindrical dielectric body 3, respectively.
is formed, and an electrode film is formed on one end surface to short-circuit the inner conductor 4 and outer conductor 5, so that they resonate at l/4 wavelength, and from the open end side, the inner conductor on the inner peripheral surface 4
The terminal 6 is inserted so as to make contact with the terminal 6. 7 is a dielectric substrate on which a capacitor electrode 8 for contacting the terminal 6 and the like is formed. This capacitor electrode 8 is for electrostatically coupling the dielectric coaxial resonators 1 to each other and the dielectric coaxial resonator 1 to an external circuit.

In such a configuration, each dielectric coaxial resonator l has its outer conductor 5 pressed against the bottom wall surface 9 via a metal spring material when the top cover of the case 2 (not shown) is covered, and the outer conductor 5 of each dielectric coaxial resonator l is By using the adhesive, mechanical retention is achieved and the outer conductor 5 is electrically connected to the case 2.

(Problem to be Solved by the Invention) By the way, in such a configuration, it is undesirable for the dielectric coaxial resonator l to move within the case 2 and shift its storage position during handling. It is necessary to fix the housing position of the body coaxial resonator 1. For this reason, in the past, a recess corresponding to the outer peripheral surface of the dielectric coaxial resonator 1 was formed on the bottom wall of the case 2, or a metal spring with a complicated shape was interposed between the bottom wall and the outer peripheral surface. There is something.

However, in conventional storage structures, the case 2 is made of die-cast aluminum, so even if a recess is formed on the bottom wall of the case 2, the dielectric coaxial resonator l can be fixed and fixed with high precision. Moreover, since it is made of die-cast aluminum (specific gravity is about 2.7), the overall weight is very heavy. Also,
Not only does the number of parts increase with metal springs, but it is also not always easy to mount the metal springs accurately, and there remains room for improvement in terms of stable mounting of the dielectric coaxial resonator ■.

The present invention has been made in view of these circumstances, and the first objective of the present invention is to reduce the weight.

A second object of the present invention is to reduce the number of parts.

A third objective of the present invention is miniaturization.

A fourth object of the present invention is to reduce the cost.

A fifth object of the present invention is to ensure electrical continuity between a predetermined location of the electronic component and the case.

(Means and effects for solving the problems) The present invention has the following features:
To achieve this purpose, in an electronic component storage structure in which electronic components are arranged and stored in a case, the case is made of elastic resin, and the inner wall of the case has a structure in which the electronic components are sandwiched. At least one pair of clamping portions are integrally formed with a predetermined distance therebetween;
Both the clamping parts are pushed apart by a distance larger than the predetermined interval by a pressing force from the outer peripheral surface of the electronic component when the electronic component is clamped, and a metal plating film is formed on at least a part of the clamping part. The basic feature is that it is electrically connected to a predetermined location of the electronic component.

(Effects) According to the present invention, since the case that houses the electronic components is made of resin (for example, its specific gravity is about 1.6), the overall weight of the housing structure is significantly reduced. Additionally, the number of parts can be reduced because metal springs are no longer required. Additionally, a case is usually divided into two parts, and the electronic components are stored inside, and then assembled using screws. However, if the case is made of resin, the case cannot be assembled using ultrasonic welding, for example. Because it can be done, it can be made smaller and costs can be reduced. Furthermore, since the electronic component is held between two holding parts, and the holding parts are pushed apart by the electronic component beyond a predetermined distance from each other, the holding parts must be held in a manner that presses against the electronic component. As a result, the electronic component can be stably arranged and housed in a predetermined position within the case, and electrical continuity between the predetermined location of the electronic component and the case can be ensured.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the drawings. FIG. 1 is a side sectional view of an electronic component storage structure according to an embodiment of the present invention. This embodiment is applied to a case in which a plurality of dielectric coaxial resonators are housed as electronic components in a case. The dielectric coaxial resonator 1 shown in FIG.
It has a structure similar to that described based on the figure.

The box-shaped case 10 in the storage structure of this embodiment is made of elastic resin such as nylon, polyacetal, AB, etc.
It is made of industrial resin such as S. The case 10 is also plated with, for example, an electrode film on its inner circumferential surface to provide at least a ground current path, and when the case 10 is covered with a top cover 15, they face each other with the dielectric coaxial resonator 1 in between. Of the two opposing walls 11.12 constituted by the case 10 and the upper lid I5, a pair of sandwiching portions 13.14 that sandwich each dielectric coaxial resonator 1 are provided on the opposing wall 12 on the case 10 side. It is formed for each dielectric coaxial resonator l. Each of these clamping portions 13, 14 is formed with a predetermined distance Ll from each other.

When the dielectric coaxial resonator I is not sandwiched between the sandwiching portions 13 and 14, they face each other at an interval of LL, but when the dielectric coaxial resonator I is sandwiched between the sandwiching portions 13 and 14, the dielectric coaxial Due to the pressing force from the outer circumferential surface 16 of the resonator 1, the resonator 1 is expanded to a distance L2 larger than the predetermined distance L1.

That is, as shown in FIG. 2, when the sandwiching parts 13 and 14 do not sandwich the dielectric coaxial resonator 1, the distance between them is Ll, but when they sandwich the dielectric coaxial resonator l,
The distance between them is L2. In this case, the clamping part 13.1
4 has elasticity, so when the distance becomes L2, a force that tries to return to the original distance in the direction of ff1LI is applied, and this causes the dielectric coaxial resonator 1 to return to the first position due to this return force. There is no deviation in the horizontal direction in the figure. Furthermore, since the opposing wall surface 12 on the case 10 side and the opposing wall 11 on the top cover 15 side are located in the vertical direction in FIG. 1, the dielectric coaxial resonator l will not shift in that direction.

The connection between the outer conductor 5 and the plated electrode film provided on the case 10 is always maintained due to the elastic force of the clamping portion.

In addition, although the example has been explained using a dielectric coaxial resonator as an electronic component, it is not limited to the dielectric coaxial resonator of the example, and in short, any electronic component that is housed in a case can be used. It is applicable.

The outer cross-sectional shape of the dielectric coaxial resonator 1 may be rectangular instead of circular as shown.

A clamping portion may also be formed on the upper lid 15.

In place of the case IO and the upper MI5, a case may be used in which a holding portion is integrally formed on the inner wall of a two-part case (referring to something like a skin in the middle). In this case, there is an advantage that the number of parts types can be further reduced.
