Description

本発明は高周波フィルタの部品間の結合構造、及びそのような結合構造を含む高周波フィルタに関するものであり、より詳細には、高周波フィルタで共振棒とハウジングの底部との間の結合、及び入出力端子のコネクタとハウジングの側壁部との間の結合などをねじ込み方式によらず、共振棒やコネクタなどの部品に特殊な構造を導入して、ハウジングの底部や側壁部などに押圧して結合することにより、組立時の管理の簡易化及び高周波フィルタの小型化を達成することができる高周波フィルタの部品間の結合構造、及びそのような結合構造を含む高周波フィルタに関するものである。 The present invention relates to a coupling structure between components of a high frequency filter and a high frequency filter including such a coupling structure, and more specifically, a coupling between a resonance rod and the bottom of a housing in a high frequency filter, and input / output. Regardless of the screwing method, the connection between the terminal connector and the side wall of the housing is not limited to the screwing method, but a special structure is introduced into parts such as the resonance rod and the connector, and the connection is pressed against the bottom and side walls of the housing. The present invention relates to a coupling structure between components of a high-frequency filter that can achieve simplification of management at the time of assembly and miniaturization of the high-frequency filter, and a high-frequency filter including such a coupling structure.

高周波フィルタは高周波、特に超高周波を共振するための一種の回路筒体の構造を有する。一般的なコイルとコンデンサによる共振回路は輻射損失が大きいため、超高周波を形成するのに適していない。よって、ＲＦフィルタは複数の共振器で構成する。各共振器は導体で取り囲まれた金属性の円筒又は直方体などの収容空間（ｃａｖｉｔｙ）を形成し、その内部には誘電体共振素子（Ｄｉｅｌｅｃｔｒｉｃ Ｒｅｓｏｎａｎｃｅ（ＤＲ） ｅｌｅｍｅｎｔ）又は金属共振棒で構成された共振素子を備えて固有周波数の電磁場のみが存在するようにすることで、超高周波の共振が可能にする構造を有する。 The high frequency filter has a kind of circuit cylinder structure for resonating high frequencies, particularly ultra high frequencies. A general coil-capacitor resonant circuit has a large radiation loss and is not suitable for forming ultra-high frequencies. Therefore, the RF filter is composed of a plurality of resonators. Each resonator forms a accommodation space (cavity) such as a metallic cylinder or a rectangular body surrounded by a conductor, and is composed of a dielectric resonance element (DR) element or a metal resonance rod inside the cavity. It has a structure that enables ultra-high frequency resonance by providing a resonance element so that only an electromagnetic field having a natural frequency exists.

通常の高周波フィルタが図１及び図２に示されている。図１及び図２を参照すると、通常の高周波フィルタ１０は一側面が開放され、内部に収容空間が形成されたハウジング１００を有する。ハウジング１００は、その内部に収容空間を有する、例えば、直方体状に形成することができる。従って、ハウジング１００は底部１１０と側壁部１２０を含む。ハウジング１００は、その内部に複数の金属共振棒３００を収容することができるように、内部収容空間が隔壁１３０によって区画される構造を有する。ハウジング１００の開放された面はカバー２００によって覆われる。カバー２００にはチューニングスクリュー４００が設置されている。ハウジング１００の側壁部１２０には入出力端子のコネクタ５００が設置されている。 Normal high frequency filters are shown in FIGS. 1 and 2. Referring to FIGS. 1 and 2, a normal high frequency filter 10 has a housing 100 having one side open and an accommodation space formed therein. The housing 100 can be formed in a rectangular parallelepiped shape, for example, having a storage space inside the housing 100. Therefore, the housing 100 includes a bottom 110 and a side wall 120. The housing 100 has a structure in which the internal accommodation space is partitioned by the partition wall 130 so that a plurality of metal resonance rods 300 can be accommodated therein. The open surface of the housing 100 is covered by the cover 200. A tuning screw 400 is installed on the cover 200. An input / output terminal connector 500 is installed on the side wall portion 120 of the housing 100.

ハウジング１００の底部１１０に金属共振棒３００を結合する際には、締結ねじ６１０を使用する。より具体的に言えば、金属共振棒３００は、その底部に締結ねじ６１０と結合するネジ締結溝を有し、ハウジング１００の底部１１０にはねじ締結孔が形成されている。締結ねじ６１０をハウジング１００の底部１１０に形成されたねじ締結孔に挿通させた後、金属共振棒３００に設けられたねじ締結溝に嵌め込むことにより、ハウジング１００の底部１１０に金属共振棒３００を固定させることができる。 When connecting the metal resonance rod 300 to the bottom 110 of the housing 100, a fastening screw 610 is used. More specifically, the metal resonance rod 300 has a screw fastening groove for connecting to the fastening screw 610 at the bottom thereof, and a screw fastening hole is formed at the bottom 110 of the housing 100. After inserting the fastening screw 610 into the screw fastening hole formed in the bottom 110 of the housing 100, the metal resonance rod 300 is fitted into the bottom 110 of the housing 100 by fitting it into the screw fastening groove provided in the metal resonance rod 300. Can be fixed.

ところで、このようなねじ込み方式は部品によってサイズが異なる締結ねじ６１０を使用しなければないため、締結ねじ６１０のサイズに合わせて異なるトルク（回転力）を適用して組み立てなければならない。このような点で、管理項目が多くなる欠点があった。それだけでなく、締結ねじ６１０はテーパーした形態（傾斜した形態）の頭部を有し、このような頭部がハウジング１００の底部１１０に設けられたねじ締結孔に結合しなければならない。そのため、ハウジング１００の底部１１０の厚さを薄くするには限界があった。このような理由から、通常の高周波フィルタ１０を小型化するには限界があった。 By the way, since such a screwing method must use fastening screws 610 having different sizes depending on the parts, it is necessary to apply different torques (rotational forces) according to the size of the fastening screws 610 for assembly. In this respect, there is a drawback that the number of management items increases. Not only that, the fastening screw 610 has a tapered (tilted) head, which must be coupled to a screw fastening hole provided in the bottom 110 of the housing 100. Therefore, there is a limit to reducing the thickness of the bottom 110 of the housing 100. For this reason, there is a limit to miniaturizing the ordinary high-frequency filter 10.

一方、カバー２００をハウジング１００と結合するには締結ねじ６３０を使用し、また、ハウジング１００の側壁部１２０に入出力端子のコネクタ５００を設置するためにも締結ネジ６２０を使用する。このような締結ねじ６３０及び６２０の使用による問題は前述した通りである。特に、コネクタ５００をハウジング１００の側壁部１２０に設置するために、コネクタ５００にフランジ５０５を一体に形成し、フランジ５０５を複数の締結ねじ６２０によってハウジング１００の側壁部１２０に結合させる構造を採用するが、このような結合構造は前述した問題点をさらに悪化させる。 On the other hand, a fastening screw 630 is used to connect the cover 200 to the housing 100, and a fastening screw 620 is also used to install the input / output terminal connector 500 on the side wall portion 120 of the housing 100. The problems caused by the use of such fastening screws 630 and 620 are as described above. In particular, in order to install the connector 500 on the side wall portion 120 of the housing 100, a structure is adopted in which the flange 505 is integrally formed with the connector 500 and the flange 505 is connected to the side wall portion 120 of the housing 100 by a plurality of fastening screws 620. However, such a coupling structure further exacerbates the above-mentioned problems.

韓国特許登録第１０−１２１７１８４号は無線周波数フィルタを開示する。開示された発明はハウジングカバーとハウジング本体との間にハウジングの気密層を挿入し、ハウジングの気密層を溶融させた後、固化させることにより、ハウジングカバーとハウジング本体を結合して受動相互変調歪み（Ｐａｓｓｉｖｅ Ｉｎｔｅｒ−Ｍｏｄｕｌａｔｉｏｎ Ｄｉｓｔｏｒｔｉｏｎ：ＰＩＭＤ）を減らすものである。この特許発明は、金属棒気密層をハウジング本体と共振金属棒との間に挿入して、同一の方式でハウジング本体と共振金属棒を結合する。この特許発明は前述した通常の高周波フィルタの問題点を解決するために案出されたものではないが、ねじ込み方式を回避するものであるため、そのような問題は現れないこともあり得る。ただし、ハウジング気密層と金属棒気密層による結合は機械的構造による結合方式ではなく、物理化学的接着結合方式に該当して耐久性に疑問があった。 Korean Patent Registration No. 10-1217184 discloses a radio frequency filter. In the disclosed invention, an airtight layer of the housing is inserted between the housing cover and the housing body, and the airtight layer of the housing is melted and then solidified to combine the housing cover and the housing body to form a passive intermodulation distortion. (Passive Inter-Modulation Distortion: PIMD) is reduced. In this patented invention, the metal rod airtight layer is inserted between the housing body and the resonant metal rod, and the housing body and the resonant metal rod are coupled in the same manner. Although this patented invention has not been devised to solve the problems of the above-mentioned ordinary high-frequency filter, such a problem may not appear because it avoids the screwing method. However, the bond between the housing airtight layer and the metal rod airtight layer is not a mechanical structure bonding method, but a physicochemical adhesive bonding method, and there is a question about durability.

そこで、本発明は前述した通常の高周波フィルタの問題点、即ち組立時の管理項目が多くなるという点と、小型化が難しいという点を改善するために案出されたものである。 Therefore, the present invention has been devised to improve the problems of the above-mentioned ordinary high-frequency filter, that is, the number of control items at the time of assembly increases and the difficulty of miniaturization.

従って、本発明の目的は高周波フィルタで共振棒とハウジングの底部との間の結合、及び入出力端子のコネクタとハウジングの側壁部との間の結合などをねじ込み方式によらず、共振棒やコネクタなどの部品に特殊な構造を導入して、ハウジングの底部や側壁部などに押圧して結合することにより、組立時の管理の簡易化及び高周波フィルタの小型化を達成することができる高周波フィルタの部品間の結合構造、及びそのような結合構造を含む高周波フィルタを提供することにある。 Therefore, an object of the present invention is to use a high-frequency filter to connect the resonance rod and the bottom of the housing, and the connection between the input / output terminal connector and the side wall of the housing, regardless of the screwing method. By introducing a special structure to parts such as the above and pressing and connecting to the bottom and side walls of the housing, it is possible to achieve simplification of management at the time of assembly and miniaturization of the high frequency filter. It is an object of the present invention to provide a coupling structure between components and a high frequency filter including such a coupling structure.

前述した目的を達成するための本発明に係る高周波フィルタの部品間の結合構造は、円形又は多角形の穴が貫設されている板状本体部の領域を含み、高周波フィルタに使用される第１部品；及び前記第１部品の前記円形又は多角形の穴の内径に一致するように挿入され、円板又は多角形板形状を有する挿入末端部、前記挿入末端部の直径より大きい直径を有する円板、多角形板、円柱又は角柱形状の係止本体部、及び前記挿入末端部の直径より小さい直径を有して前記挿入末端部と前記係止本体部を連結し、円板又は多角形板形状を有する連結部を含む、高周波フィルタに使用される第２部品との間の結合構造である。 The coupling structure between the parts of the high frequency filter according to the present invention for achieving the above-mentioned object includes a region of a plate-shaped main body through which a circular or polygonal hole is formed, and is used for the high frequency filter. 1 part; and an insertion end portion inserted to match the inner diameter of the circular or polygonal hole of the first part and having a disk or polygonal plate shape, having a diameter larger than the diameter of the insertion end portion.

Manufactured from a material, by arranging a support under the first component and pressing the first component, a coupling structure between the first component and the second component is completed. At this time, in the coupling structure between the first component and the second component, the connecting portion and the insertion end portion of the second component are inserted into the circular or polygonal hole of the first component. When the second component is pressed while the locking main body of the second component is locked to the main body of the first component, the second component is located below the locking body of the second component. It is formed by filling the annular gap formed between the locking main body and the insertion end of the second component in the process of pushing the main body portion of the first component downward.

Regardless, by introducing a special structure to parts such as resonance rods and connectors and pressing and connecting them to the bottom and side walls of the housing, we have achieved simplification of management during assembly and miniaturization of high-frequency filters. It is possible to do.

A feature of the present invention is that the coupling structure between the components of the high-frequency filter, which will be specifically described below, is different from the corresponding coupling structure of a normal high-frequency filter. Therefore, since FIG. 1 can be referred to for the overall shape of the high frequency filter 10 of the present invention, detailed description thereof will be omitted here.

図３は本発明の一実施形態に係る高周波フィルタの部品間の結合構造をなす過程を説明するための断面図である。ここで、第１部品は高周波フィルタ１０のハウジング１００の底部１１０であり、第２部品は金属共振棒３００である。 FIG. 3 is a cross-sectional view for explaining a process of forming a coupling structure between parts of a high-frequency filter according to an embodiment of the present invention. Here, the first component is the bottom 110 of the housing 100 of the high frequency filter 10, and the second component is the metal resonance rod 300.

図３に示したように、本発明において第１部品であるハウジング１００の底部１１０は板状本体部の領域を含み、そのような本体部には円形の穴１１２が貫設されている。円形の穴１１２の代わりに、多角形の穴を形成することも可能である。以下では円形の穴１１２を基準に説明することにする。 As shown in FIG. 3, the bottom portion 110 of the housing 100, which is the first component in the present invention, includes a region of a plate-shaped main body portion, and a circular hole 112 is formed in such a main body portion. Instead of the circular hole 112, it is also possible to form a polygonal hole. Hereinafter, the description will be made with reference to the circular hole 112.

一方、本発明において第２部品である金属共振棒３００は挿入末端部３１０、係止本体部３２０及び連結部３３０を含む。金属共振棒３００のその他の構成は通常の金属共振棒同じであり得る。 On the other hand, the metal resonance rod 300, which is the second component in the present invention, includes an insertion end portion 310, a locking main body portion 320, and a connecting portion 330. Other configurations of the metal resonance rod 300 can be the same as that of a normal metal resonance rod.

共振棒３００の挿入末端部３１０はハウジング底部１１０に形成された円形の穴１１２の内径に一致するように挿入される。従って、挿入末端部３１０は円板状である。もしハウジング底部１１０が円形の穴１１２の代わりに、多角形の穴を有する場合、挿入末端部３１０は多角形板状を有しなければならないことは当然である。 The insertion end 310 of the resonance rod 300 is inserted so as to match the inner diameter of the circular hole 112 formed in the bottom 110 of the housing. Therefore, the insertion end portion 310 has a disk shape. If the bottom 110 of the housing has a polygonal hole instead of the circular hole 112, it is natural that the insertion end 310 must have a polygonal plate shape.

共振棒３００の係止本体部３２０は挿入末端部３１０の直径より大きい直径を有する円板又は円柱状に形成される。もしハウジング底部１１０が円形の穴１１２の代わりに、多角形の穴を有する場合、係止本体部３２０は多角形板又は角柱形状に形成することができる。このとき、係止本体部３２０から延びて共振棒３００の残りの構成を形成することができる。 The locking body portion 320 of the resonance rod 300 is formed in a disk or columnar shape having a diameter larger than the diameter of the insertion end portion 310. If the housing bottom 110 has polygonal holes instead of circular holes 112, the locking body 320 can be formed in the shape of a polygonal plate or prism. At this time, the remaining configuration of the resonance rod 300 can be formed by extending from the locking main body 320.

共振棒３００の連結部３３０は挿入末端部３１０の直径より小さい直径を有する挿入末端部３１０と係止本体部３２０を連結するものである。連結部３３０は円板状である。もしハウジング底部１１０が円形の穴１１２の代わりに、多角形の穴を有する場合、連結部３３０は多角形板状に形成することができる。 The connecting portion 330 of the resonance rod 300 connects the insertion end portion 310 having a diameter smaller than the diameter of the insertion end portion 310 and the locking main body portion 320. The connecting portion 330 has a disk shape. If the housing bottom 110 has polygonal holes instead of circular holes 112, the connecting portion 330 can be formed in the shape of a polygonal plate.

共振棒３００がこのような構造で形成されるので、係止本体部３２０と挿入末端部３１０との間に環状間隙３４０が形成される。前述した挿入末端部３１０、連結部３３０及び係止本体部３２０は一体に形成されることが好ましい。 Since the resonance rod 300 is formed with such a structure, an annular gap 340 is formed between the locking main body portion 320 and the insertion end portion 310. It is preferable that the insertion end portion 310, the connecting portion 330, and the locking main body portion 320 described above are integrally formed.

本発明において第２部品である共振棒３００は第１部品であるハウジング底部１１０を構成する金属材料の硬度より大きい硬度を有する金属材料で製造される。例えば、共振棒３００は真鍮、鉄又はステンレス鋼で製造することができ、ハウジング底部１１０はアルミニウム、銅めっきされたアルミニウム又は銀メッキされたアルミニウムで製造することができる。 In the present invention, the resonance rod 300, which is the second component, is manufactured of a metal material having a hardness higher than the hardness of the metal material constituting the housing bottom 110, which is the first component. For example, the resonant rod 300 can be made of brass, iron or stainless steel, and the housing bottom 110 can be made of aluminum, copper plated aluminum or silver plated aluminum.

共振棒３００をハウジング底部１１０に結合するためには、図３には図示しなかったが、ハウジング底部１１０の下に支持台を配置して共振棒３００を適切なジグを用いて押圧することにより、ハウジング底部１１０と共振棒３００との間の結合構造を完成することができる。この時、支持台は、押圧力により発生するハウジング底部１１０の変形がハウジング底部１１０の下側の境界領域を超えて下方に伝播されることを防ぐ程度の硬度を有するものであれば何でもよい。 In order to connect the resonance rod 300 to the bottom 110 of the housing, although not shown in FIG. 3, by arranging a support base under the bottom 110 of the housing and pressing the resonance rod 300 with an appropriate jig. , The coupling structure between the housing bottom 110 and the resonance rod 300 can be completed. At this time, the support base may be any one having a hardness sufficient to prevent the deformation of the housing bottom 110 generated by the pressing force from being propagated downward beyond the lower boundary region of the housing bottom 110.

具体的に、共振棒３００の挿入末端部３１０がハウジング底部１１０に設けられた円形の穴１１２に一致するようにジグ（図示せず）に共振棒３００を固定した後、下方力を作用させて共振棒３００を下方に移動させる（図３の一番目の図）。そうすると、共振棒３００の挿入末端部３１０と連結部３３０は、ハウジング底部１１０に形成された円形の穴１１２に挿入され、共振棒３００の係止本体部３２０は円形の穴１１２に挿入されないため、ハウジング底部１１０に係止された状態になる（図３の二番目の図）。この状態で引き続き共振棒３００を押圧すると、係止本体部３２０の硬度がハウジング底部１１０の硬度より大きいため、係止本体部３２０の下に位置するハウジング底部１１０の部分は係止本体部３２０によって下方に押圧される（図３の三番目の図）。即ち、ハウジング底部１１０の該当部分に垂直変形が発生するようになる。ところで、このような過程でハウジング底部１１０は支持台に配置されているので、押圧力により発生するハウジング底部１１０の垂直変形はハウジング底部１１０の下側の境界領域を超えて下方に伝播することができない。従って、結局はハウジング底部１１０の垂直変形は水平変形に変換されて、ハウジング底部１１０のそのような変形部分が係止本体部３２０と挿入末端部３１０との間に形成された環状間隙３４０を満たすようになる（図３の四番目の図）。 Specifically, after fixing the resonance rod 300 to a jig (not shown) so that the insertion end portion 310 of the resonance rod 300 coincides with the circular hole 112 provided in the bottom portion 110 of the housing, a downward force is applied. The resonance rod 300 is moved downward (first diagram of FIG. 3). Then, the insertion end portion 310 and the connecting portion 330 of the resonance rod 300 are inserted into the circular hole 112 formed in the bottom portion 110 of the housing, and the locking body portion 320 of the resonance rod 300 is not inserted into the circular hole 112. It is locked to the bottom 110 of the housing (second figure in FIG. 3). If the resonance rod 300 is continuously pressed in this state, the hardness of the locking main body 320 is larger than the hardness of the housing bottom 110, so that the housing bottom 110 located below the locking main body 320 is formed by the locking main body 320. It is pressed downward (third figure in FIG. 3). That is, vertical deformation occurs in the corresponding portion of the housing bottom 110. By the way, since the housing bottom 110 is arranged on the support base in such a process, the vertical deformation of the housing bottom 110 generated by the pressing force may propagate downward beyond the lower boundary region of the housing bottom 110. Can not. Therefore, in the end, the vertical deformation of the housing bottom 110 is converted into a horizontal deformation, and such a deformed portion of the housing bottom 110 fills the annular gap 340 formed between the locking body 320 and the insertion end 310. (Fourth figure in Fig. 3).

前述した過程によりハウジング底部１１０の水平変形によって新たに生成された突出部が共振棒３００の環状間隙３４０に嵌め込まれることにより、共振棒３００とハウジング底部１１０との間の結合が強固に行われる。図４を参照すると、ハウジング底部１１０の（１）部分は共振棒３００の押圧過程中で下方に押されるようになり、そのようなハウジング底部１１０の垂直変形は水平変形に変換されて、結局はハウジング底部１１０の（２）部分が突出して新たに形成される。ハウジング底部１１０から突出して新たに形成された（２）部分は共振棒３００の環状間隙３４０に嵌め込まれて、ハウジング底部１１０と共振棒３００が結合されるようになる。従って、ハウジング底部１１０の厚さによって共振棒３００の挿入末端部３１０と連結部３３０の厚さを適切に選択すると、前述のような結合構造を実現することができるようになる。 The protrusion newly generated by the horizontal deformation of the housing bottom 110 by the process described above is fitted into the annular gap 340 of the resonance rod 300, so that the coupling between the resonance rod 300 and the housing bottom 110 is firmly performed. Referring to FIG. 4, the portion (1) of the housing bottom 110 is pushed downward during the pressing process of the resonant rod 300, and such vertical deformation of the housing bottom 110 is converted into horizontal deformation and eventually. The portion (2) of the housing bottom 110 protrudes and is newly formed. The newly formed portion (2) protruding from the bottom portion 110 of the housing is fitted into the annular gap 340 of the resonance rod 300 so that the bottom portion 110 of the housing and the resonance rod 300 are coupled. Therefore, if the thickness of the insertion end portion 310 and the connecting portion 330 of the resonance rod 300 is appropriately selected according to the thickness of the housing bottom portion 110, the coupling structure as described above can be realized.

本発明に係る高周波フィルタの部品間の結合構造は、部品の組立時にハウジング底部１１０のせん断強度以上の力でジグを用いて共振棒３００を押圧するだけで十分である。そのため、部品の組立時の管理が簡単で容易である。必要な場合、ハウジング底部１１０の円形の穴１１２に対して共振棒３００を押圧する長さをさらに管理することができる。このように、押圧長さの追加管理も難なく行うことができる。従って、本発明に係る高周波フィルタは通常の高周波フィルタに比べて部品の組み立てが簡単で容易であるという長所を有する。 For the coupling structure between the parts of the high-frequency filter according to the present invention, it is sufficient to press the resonance rod 300 with a jig with a force equal to or higher than the shear strength of the housing bottom 110 at the time of assembling the parts. Therefore, it is easy and easy to manage when assembling parts. If necessary, the length of pressing the resonant rod 300 against the circular hole 112 of the bottom 110 of the housing can be further controlled. In this way, additional management of the pressing length can be performed without difficulty. Therefore, the high-frequency filter according to the present invention has an advantage that parts can be easily and easily assembled as compared with a normal high-frequency filter.

図５は本発明の一実施形態に係る高周波フィルタの部品間の結合構造に適用される共振棒（第２部品）の形状を例示した斜視図である。図５の共振棒３００において、係止本体部３２０にはＤカット部３２５が設けられている。Ｄカット部３２５は連結部３３０と連結される係止本体部３２０の末端面から垂直に切断した後水平に切断して、Ｄ形状の断面を有する切断物を除去することにより、係止本体部３２０の側面の一部に平らに形成される。 FIG. 5 is a perspective view illustrating the shape of the resonance rod (second component) applied to the coupling structure between the components of the high-frequency filter according to the embodiment of the present invention. In the resonance rod 300 of FIG. 5, a D-cut portion 325 is provided on the locking main body portion 320. The D-cut portion 325 is vertically cut from the end surface of the locking main body 320 connected to the connecting portion 330 and then horizontally cut to remove a cut piece having a D-shaped cross section, thereby removing the locking main body. It is formed flat on a part of the side surface of the 320.

前述したように、共振棒３００がハウジング底部１１０の円形の穴１１２に押圧される際に、ハウジング底部１１０の垂直変形が水平変形に転換されてハウジング底部１１０に突出部が形成され、このような突出部は共振棒３００の環状間隙３４０に嵌め込まれる。この時、共振棒３００の係止本体部３２０にＤカット部３２５が形成されている場合、ハウジング底部１１０はＤカット部３２５に対応する部分では垂直変形を起こさない。そのため、ハウジング底部１１０はＤカット部３２５により共振棒３００の係止本体部３２０に係止されるようになる。 As described above, when the resonance rod 300 is pressed against the circular hole 112 of the housing bottom 110, the vertical deformation of the housing bottom 110 is converted into the horizontal deformation to form a protrusion on the housing bottom 110, such as this. The protruding portion is fitted into the annular gap 340 of the resonance rod 300. At this time, when the D-cut portion 325 is formed on the locking body portion 320 of the resonance rod 300, the housing bottom portion 110 does not undergo vertical deformation at the portion corresponding to the D-cut portion 325. Therefore, the housing bottom 110 is locked to the locking body 320 of the resonance rod 300 by the D-cut portion 325.

従って、共振棒３００の係止本体部３２０にＤカット部３２５が更に設けられると、共振棒３００をハウジング底部１１０の円形の穴１１２に押圧した後、共振棒３００が回転することを確実に阻止する。 Therefore, when the D-cut portion 325 is further provided in the locking body portion 320 of the resonance rod 300, the resonance rod 300 is surely prevented from rotating after being pressed into the circular hole 112 of the bottom portion 110 of the housing. do.

図６は図３及び図４に示した高周波フィルタの部品間の結合構造を通常の高周波フィルタの部品間の結合構造と比較した断面図である。図６に示したように、通常の高周波フィルタにおいて共振棒３００をハウジング底部１１０に結合するために締結ねじ６１０を採用する。そのため、ハウジング底部１１０の厚さは最小限にしても２ｍｍより大きくしなければならない。通常の高周波フィルタにおいてハウジング底部１１０の厚さは、例えば２〜４ｍｍ又はそれ以上でなければならない。反面、本発明に係る高周波フィルタにおいては前述した結合構造によって共振棒３００とハウジング底部１１０が結合するので、２ｍｍ以下の厚さでハウジング底部１１０を形成することができる。本発明の高周波フィルタにおいて共振棒３００と結合するハウジング底部１１０の厚さは１〜２ｍｍで設計することができ、より正確に設計する場合は、それよりも小さな厚さ、例えば、１〜０．５ｍｍ程度の厚さでハウジング底部１１０を設計することもできる。 FIG. 6 is a cross-sectional view comparing the coupling structure between the components of the high-frequency filter shown in FIGS. 3 and 4 with the coupling structure between the components of a normal high-frequency filter. As shown in FIG. 6, in a normal high frequency filter, a fastening screw 610 is adopted to connect the resonance rod 300 to the housing bottom 110. Therefore, the thickness of the housing bottom 110 must be at least 2 mm. In a normal high frequency filter, the thickness of the housing bottom 110 should be, for example, 2-4 mm or more. On the other hand, in the high frequency filter according to the present invention, since the resonance rod 300 and the housing bottom 110 are coupled by the coupling structure described above, the housing bottom 110 can be formed with a thickness of 2 mm or less. In the high frequency filter of the present invention, the thickness of the housing bottom 110 coupled to the resonance rod 300 can be designed to be 1 to 2 mm, and for more accurate design, a smaller thickness, for example, 1 to 0. It is also possible to design the housing bottom 110 with a thickness of about 5 mm.

一方、図９は本発明の一実施形態に係る高周波フィルタの部品間の結合構造を達成するために設計した共振棒（第２部品）の実際形状を撮影した写真であり、図１０は本発明の一実施形態に係る高周波フィルタの部品間の結合構造を達成するためのハウジングの底部（第１部品）を模写した金属板の形状を撮影した写真であり、図１１乃至図１３は図９の共振棒を図１０のハウジング底部に結合して本発明の一実施形態として高周波フィルタの部品間の結合構造を完成した状態を撮影した写真である。この時、図１１は金属板の上部面を斜めに撮影した写真であり、図１２は側方から撮影した写真であり、図１３は金属板の下部面を撮影した写真である。図９乃至図１３から確認できるように、本発明に係る高周波フィルタの部品間の結合構造は設計した通りよく実現された。 On the other hand, FIG. 9 is a photograph of the actual shape of the resonance rod (second component) designed to achieve the coupling structure between the components of the high-frequency filter according to the embodiment of the present invention, and FIG. 10 is a photograph of the present invention. 11 to 13 are photographs of the shape of a metal plate that imitates the bottom portion (first component) of the housing for achieving the coupling structure between the components of the high-frequency filter according to the embodiment. It is a photograph of the state in which the resonance rod is coupled to the bottom of the housing of FIG. 10 and the coupling structure between the components of the high frequency filter is completed as one embodiment of the present invention. At this time, FIG. 11 is a photograph of the upper surface of the metal plate obliquely taken, FIG. 12 is a photograph taken from the side, and FIG. 13 is a photograph of the lower surface of the metal plate. As can be confirmed from FIGS. 9 to 13, the coupling structure between the components of the high-frequency filter according to the present invention was well realized as designed.

図７は本発明の他の実施形態に係る高周波フィルタの部品間の結合構造を通常の高周波フィルタの部品間の結合構造と比較した図である。 FIG. 7 is a diagram comparing the coupling structure between components of a high-frequency filter according to another embodiment of the present invention with the coupling structure between components of a normal high-frequency filter.

図７を参照すると、本発明の高周波フィルタにおいて第１部品はハウジング１００の側壁部１２０であり、第２部品は入出力端子のコネクタ５００であり得る。従って、ハウジング側壁部１２０にはハウジング底部１１０に設けられた円形の穴１１２に対応する円形の穴１２２が形成されており、コネクタ５００は挿入末端部５１０、係止本体部５２０、及び連結部５３０を有する。コネクタ５００の挿入末端部５１０、係止本体部５２０、及び連結部５３０は前述したように、共振棒３００の挿入末端部３１０、係止本体部３２０、及び連結部３３０が円形の穴１１２を備えたハウジング底部１１０に対して有する結合機能及び技術的効果と同じ機能及び効果を、円形の穴１２２を備えたハウジング側壁部１２０に対して発揮することができる。 Referring to FIG. 7, in the high frequency filter of the present invention, the first component may be the side wall portion 120 of the housing 100, and the second component may be the connector 500 of the input / output terminal. Therefore, the side wall portion 120 of the housing is formed with a circular hole 122 corresponding to the circular hole 112 provided in the bottom portion 110 of the housing, and the connector 500 has an insertion end portion 510, a locking main body portion 520, and a connecting portion 530. Has. As described above, the insertion end portion 510, the locking body portion 520, and the connecting portion 530 of the connector 500 are provided with holes 112 in which the insertion end portion 310, the locking body portion 320, and the connecting portion 330 of the resonance rod 300 are circular. The same function and effect as the coupling function and technical effect of the housing bottom 110 can be exerted on the housing side wall 120 provided with the circular hole 122.

一方、コネクタ５００は係止本体部５２０の直径より小さい直径を有する円柱状のコネクタ本体部５５０を含む。コネクタ本体部５５０は係止本体部５２０上の同心円の位置に設置される。この時、コネクタ５００をハウジング側壁部１２０に結合するためにジグにより握られる部分とジグにより押される部分はコネクタ本体部５５０ではなく、係止本体部５２０であることが好ましい。このため、係止本体部５２０の直径をコネクタ本体部５５０の直径より大きく形成するものである。コネクタ本体部５５０がジグにより握られて押された場合は、そのような過程でコネクタ本体部５５０が損傷する恐れがある。 On the other hand, the connector 500 includes a columnar connector main body 550 having a diameter smaller than the diameter of the locking main body 520. The connector main body 550 is installed at a concentric position on the locking main body 520. At this time, it is preferable that the portion gripped by the jig and the portion pushed by the jig for connecting the connector 500 to the side wall portion 120 of the housing are not the connector main body portion 550 but the locking main body portion 520. Therefore, the diameter of the locking main body 520 is formed larger than the diameter of the connector main body 550. If the connector body 550 is gripped and pushed by a jig, the connector body 550 may be damaged in such a process.

図７に示したように、通常の高周波フィルタにおいて入出力端子のコネクタ５００をハウジング側壁部１２０に結合するために締結ねじ６２０を採用する。そのため、ハウジング側壁部１１０の厚さは最小限にしても、３ｍｍより大きくしなければならない。通常の高周波フィルタにおいてハウジング側壁部１１０の厚さは、例えば３〜５ｍｍ又はそれ以上でなければならない。反面、本発明に係る高周波フィルタにおいては前述した結合構造によってコネクタ５００とハウジング側壁部１１０が結合するので、２ｍｍ以下の厚さでハウジング側壁部１２０を形成することができる。本発明の高周波フィルタにおいてコネクタ５００と結合するハウジング側壁部１１０の厚さは１〜２ｍｍで設計することができ、より正確に設計する場合は、それよりも小さな厚さ、例えば、１〜０．５ｍｍ程度の厚さでハウジング側壁部１１０を設計することもできる。 As shown in FIG. 7, in a normal high-frequency filter, a fastening screw 620 is adopted to connect the connector 500 of the input / output terminal to the side wall portion 120 of the housing. Therefore, the thickness of the side wall portion 110 of the housing must be made larger than 3 mm at the minimum. In a normal high frequency filter, the thickness of the side wall portion 110 of the housing should be, for example, 3 to 5 mm or more. On the other hand, in the high frequency filter according to the present invention, since the connector 500 and the housing side wall portion 110 are coupled by the above-mentioned coupling structure, the housing side wall portion 120 can be formed with a thickness of 2 mm or less. In the high frequency filter of the present invention, the thickness of the side wall portion 110 of the housing to be coupled to the connector 500 can be designed to be 1 to 2 mm, and for more accurate design, a smaller thickness, for example, 1 to 0. It is also possible to design the housing side wall portion 110 with a thickness of about 5 mm.

また、本発明によれば、通常の高周波フィルタで採用するコネクタ５００はねじ込み方式でハウジング側壁部１２０に結合するためにフランジ５０５が必要であるが、本発明に係るコネクタ５００はこのようなフランジを必要としない。従って、本発明の高周波フィルタは、このような点でさらに有用な側面を有する。 Further, according to the present invention, the connector 500 used in a normal high-frequency filter requires a flange 505 to be coupled to the housing side wall portion 120 by a screwing method, but the connector 500 according to the present invention has such a flange. do not need. Therefore, the high frequency filter of the present invention has a more useful aspect in this respect.

図８は通常の高周波フィルタの部品間の結合構造と比較して本発明に係る高周波フィルタの部品間の結合構造によって小型化が達成されることを示す図である。図８に示したように、本発明に係る高周波フィルタは共振棒３００とハウジング底部１１０が前述した結合構造で結合する。そのため、通常の高周波フィルタに比べて、その高さを少なくとも１ｍｍ以上減らすことができ、小型化の達成に寄与するようになる。 FIG. 8 is a diagram showing that miniaturization is achieved by the coupling structure between components of the high frequency filter according to the present invention as compared with the coupling structure between components of a normal high frequency filter. As shown in FIG. 8, in the high-frequency filter according to the present invention, the resonance rod 300 and the housing bottom 110 are coupled by the coupling structure described above. Therefore, the height of the filter can be reduced by at least 1 mm or more as compared with a normal high-frequency filter, which contributes to the achievement of miniaturization.
