　電気的な導通のみを目的として製造される金属部品は、一般に、表面処理において高い平面度が求められない。このような金属部品同士を嵌め合わせて１つの外導体を構成する場合、両金属部品の嵌合面同士の間に隙間が生じる。高速通信用の回路において、嵌合面同士の隙間は、不必要なキャパシタを発生させて共振現象を引き起こし、通信特性を低下させる原因となる。この対策としては、金属部品の接触面積を広く確保してインピーダンスを低下させることが考えられる。しかし、金属部品がダイキャスト製である場合は、プレス製品に比べると寸法精度や平面度が低いため、接触面積を広く確保することが難しい。 Metal parts that are manufactured solely for the purpose of electrical continuity generally do not require high flatness in surface treatment. When such metal parts are fitted together to form one outer conductor, a gap is generated between the mating surfaces of both metal parts. In a circuit for high-speed communication, a gap between mating surfaces generates an unnecessary capacitor, causes a resonance phenomenon, and deteriorates communication characteristics. As a countermeasure, it is conceivable to reduce the impedance by ensuring a wide contact area of the metal parts. However, when the metal parts are die-cast, it is difficult to secure a large contact area because the dimensional accuracy and flatness are lower than those of pressed products.
　本開示は、上記のような事情に基づいて完成されたものであって、外導体を構成する金属部品同士を、広い面積で接触させることを目的とする。 The present disclosure has been completed based on the circumstances as described above, and aims to bring the metal parts forming the outer conductor into contact with each other over a wide area.

First, the embodiments of the present disclosure will be listed and described.
The shield terminal of the first disclosure includes:
(1) An inner conductor, a dielectric surrounding the inner conductor, and an outer conductor surrounding the dielectric, wherein the outer conductor includes a plurality of metal parts that are fitted together, and at least A plurality of protrusions are formed on a fitting surface of one of the metal parts that comes into sliding contact with the other metal part during the fitting process.

According to this configuration, it is possible to form the projection by blasting with low accuracy.
　（７）２つの前記金属部品の嵌合方向に対して、前記嵌合面が斜めをなしていることが好ましい。この構成によれば、金属部品同士の嵌合過程では、複数の突部が塑性変形するタイミングが分散されるので、嵌合抵抗の最大値を低減することができる。 (7) It is preferable that the fitting surface is oblique with respect to the fitting direction of the two metal parts. According to this configuration, in the process of fitting the metal parts together, the timings of plastic deformation of the plurality of projections are dispersed, so that the maximum value of the fitting resistance can be reduced.
　（８）互いに嵌合される２つの前記金属部品は、前記複数の突部の山数ＰＰＩが異なる組合せであることが好ましい。この構成によれば、一方の金属部品の突部と他方の金属部品の突部が、必ず当接して塑性変形を生じるので、接触信頼性が高い。 (8) It is preferable that the two metal parts to be fitted to each other are a combination in which the number of peaks PPI of the plurality of protrusions is different. According to this configuration, the protrusion of one metal part and the protrusion of the other metal part always come into contact with each other to cause plastic deformation, so that the contact reliability is high.
　第２の開示の外導体は、
　（９）内導体が収容される誘電体を包囲する外導体であって、互いに嵌合される複数の金属部品を備えており、少なくとも１つの前記金属部品のうち、嵌合過程において他の前記金属部品に摺接する嵌合面には、複数の突部が形成され、前記複数の金属部品が嵌合された状態では、前記複数の突部が塑性変形した状態で前記他の金属部品に接触している。本開示の構成によれば、複数の金属部品を嵌合する過程で、１つの金属部品の嵌合面に形成された複数の突部が、他の金属部品に摺接しながら塑性変形する。この塑性変形した複数の突部によって、外導体を構成する金属部品同士を、広い面積で接触させることができる。 The outer conductor of the second disclosure is

According to the configuration of the present disclosure, in the process of fitting a plurality of metal parts, the plurality of protrusions formed on the fitting surface of one metal part are plastically deformed while being in sliding contact with other metal parts.

　［実施例１］
　本開示を具体化した実施例１のシールド端子１を、図１～図６を参照して説明する。なお、本発明はこれらの例示に限定されるものではなく、請求の範囲によって示され、請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。本実施例１において、前後の方向については、図１～３におけるＸ軸の正方向を前方と定義する。左右の方向については、図１，２，４におけるＹ軸の正方向を右方と定義する。上下の方向については、図１～４におけるＺ軸の正方向を上方と定義する。 [Details of the embodiment of the present disclosure]
[Example 1]
A shield terminal 1 of Example 1 embodying the present disclosure will be described with reference to FIGS. 1 to 6. FIG. The present invention is not limited to these exemplifications, but is indicated by the scope of the claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims. In the first embodiment, regarding the front-rear direction, the positive direction of the X-axis in FIGS. 1 to 3 is defined as the front. Regarding the left-right direction, the positive direction of the Y-axis in FIGS. 1, 2 and 4 is defined as the right side. Regarding the vertical direction, the positive direction of the Z-axis in FIGS. 1 to 4 is defined as upward.
　本実施例１のシールド端子１は、図２に示すように、１つの内導体１０と、１の誘電体１１と、１つの外導体１５とを組み付けて構成されている。内導体１０は、細長い金属材料からなり、内導体１０を側方から見た側面視において、Ｌ字形に屈曲した形状をなす。誘電体１１は、側面視形状がＬ字形をなす部品である。図３に示すように、誘電体１１の内部には、Ｌ字形をなすスリット状収容室１２が形成されている。スリット状収容室１２内には、誘電体１１の後方から内導体１０が挿入されている。 As shown in FIG. 2, the shield terminal 1 of Example 1 is constructed by assembling one inner conductor 10, one dielectric 11, and one outer conductor 15. The inner conductor 10 is made of an elongated metal material, and has an L-shaped bent shape when viewed from the side of the inner conductor 10 . The dielectric 11 is a component having an L-shape in side view. As shown in FIG. 3, an L-shaped slit-shaped accommodation chamber 12 is formed inside the dielectric 11 . The inner conductor 10 is inserted into the slit-shaped housing chamber 12 from behind the dielectric 11 .
　外導体１５は、金属製の第１部品１６と、金属製の第２部品２４とを組み付けて構成されている。第１部品１６は、直方形の本体部１７と、本体部１７から前方へ突出した円筒部１８とを有する単一部品である。本体部１７内及び円筒部１８内には、誘電体１１を収容するための収容空間１９が形成されている。本体部１７の後壁部２０には、誘電体１１を収容空間１９内に組み付けるための組付用開口部２１が形成されている。組付用開口部２１は、本体部１７の後面と下面に開口している。組付用開口部２１の左右両内側面を、一対の第１嵌合面２２と定義する。 The outer conductor 15 is configured by assembling a metal first part 16 and a metal second part 24 . The first component 16 is a single component having a rectangular body portion 17 and a cylindrical portion 18 projecting forward from the body portion 17 . A housing space 19 for housing the dielectric 11 is formed in the body portion 17 and the cylindrical portion 18 . A rear wall portion 20 of the body portion 17 is formed with an assembly opening 21 for assembling the dielectric 11 into the housing space 19 . The assembly openings 21 are opened on the rear surface and the bottom surface of the body portion 17 . The left and right inner side surfaces of the assembly opening 21 are defined as a pair of first fitting surfaces 22 .
　第２部品２４は、本体部１７に対して下から組み付けることによって、本体部１７の外面における収容空間１９の開口を閉塞する部品である。第２部品２４は、底壁部２５と、底壁部２５の後端部から上方へ柱状に立ち上がった柱状部２６とを有する単一部品である。柱状部２６の左右両外側面を、一対の第２嵌合面２７と定義する。 The second part 24 is a part that closes the opening of the accommodation space 19 on the outer surface of the body part 17 by being assembled to the body part 17 from below. The second part 24 is a single part having a bottom wall portion 25 and a columnar portion 26 rising upward from the rear end portion of the bottom wall portion 25 in a columnar shape. The left and right outer side surfaces of the columnar portion 26 are defined as a pair of second fitting surfaces 27 .
　第１部品１６と第２部品２４は、上下方向に平行移動させることによって組み付けられる。両部品１６，２４の嵌合方向は、底壁部２５から柱状部２６が立ち上がる方向と平行な方向である。第１部品１６と第２部品２４を組み付ける過程では、柱状部２６が組付用開口部２１内に対して相対的に下から嵌合され、第１嵌合面２２と第２嵌合面２７が上下方向に摺接する。第１部品１６と第２部品２４を組み付けた状態では、底壁部２５が本体部１７の下面の開口を閉塞し、柱状部２６が組付用開口部２１を閉塞する。 The first part 16 and the second part 24 are assembled by vertically translating them. The fitting direction of the two parts 16 and 24 is parallel to the direction in which the columnar portion 26 rises from the bottom wall portion 25 . In the process of assembling the first part 16 and the second part 24, the columnar part 26 is fitted into the assembly opening 21 from below, and the first fitting surface 22 and the second fitting surface 27 are fitted together. slides in the vertical direction. When the first part 16 and the second part 24 are assembled, the bottom wall part 25 closes the opening on the lower surface of the main body part 17 and the columnar part 26 closes the assembly opening 21 .
　第１部品１６は、鋳造（ダイキャスト）、鍛造又は切削によって製造された部品であるため、板状の金属部材に比べると、剛性が高い。第２部品２４も、鋳造（ダイキャスト）、鍛造又は切削によって製造された部品であるため、板状部材に比べると剛性が高い。そのため、柱状部２６を組付用開口部２１に嵌合したときに、第１嵌合面２２と第２嵌合面２７を弾性的に密着させることはできない。両嵌合面２２，２７の密着度を高めるために両部品１６，２４の寸法公差を小さくすると、柱状部２６と組付用開口部２１との間の摺動抵抗が大きくなり過ぎて、最悪の場合、嵌合不能となる。 The first part 16 is a part manufactured by casting (die casting), forging, or cutting, so it has higher rigidity than a plate-like metal member. The second part 24 is also a part manufactured by casting (die casting), forging, or cutting, so it has higher rigidity than the plate-like member. Therefore, when the columnar portion 26 is fitted into the assembly opening 21, the first fitting surface 22 and the second fitting surface 27 cannot be elastically brought into close contact with each other. If the dimensional tolerances of the parts 16 and 24 are reduced in order to increase the degree of close contact between the fitting surfaces 22 and 27, the sliding resistance between the columnar portion 26 and the assembly opening 21 becomes too large. In the case of , it becomes impossible to mate.
　この対策として、一対の第１嵌合面２２を、両部品１６，２４の嵌合方向に対して傾斜させている。一対の第１嵌合面２２の対向間隔は、第１嵌合面２２の上端側（第２部品２４の嵌合方向における先端側）に向かって次第に狭まっている。また、一対の第２嵌合面２７の左右方向の距離も、第１嵌合面２２と同様、第２嵌合面２７の上端側（第１部品１６に対する嵌合方向の先端側）に向かって次第に小さくなっている。第１嵌合面２２と第２嵌合面２７は、平行をなす。 As a countermeasure against this, the pair of first fitting surfaces 22 are inclined with respect to the fitting direction of the two parts 16 and 24 . The space between the pair of first fitting surfaces 22 facing each other gradually narrows toward the upper end side of the first fitting surfaces 22 (the tip side in the fitting direction of the second component 24). Further, the distance between the pair of second fitting surfaces 27 in the left-right direction is also the same as the first fitting surface 22, toward the upper end side of the second fitting surface 27 (toward the tip end side in the fitting direction with respect to the first component 16). gradually getting smaller. The first fitting surface 22 and the second fitting surface 27 are parallel.
　第１嵌合面２２には、梨地加工が施されており、梨地加工によって複数の突部２３が形成されている。梨地加工は、第１部品１６を鋳造するための金型に細かい凹凸を形成することによって、鋳造工程において形成することができる。また、第１部品１６を所定の形状に成形した後の後加工として、ワイヤブラシ法、ブラスト法、分散めっき法等によって行うことができる。第２嵌合面２７には、梨地加工は施されておらず、第１嵌合面２２の突部２３に相当するような突出部位を形成していない。したがって、第１嵌合面２２の面粗度は、第２嵌合面２７の面粗度よりも大きい。第１嵌合面２２の表面粗さは、算術平均粗さ（Ｒａ）、最大高さ（Ｒｙ）、十点平均粗さ（Ｒｚ）のいずれにおいても、第２嵌合面２７の表面粗さよりも大きい。第１嵌合面２２における基準面を最も低い谷底の高さと定義したときに、その基準面からの各突部２３の突出寸法は、ランダムである。第１嵌合面２２における複数の突部２３の分布については、複数の突部２３は、一定ピッチで規則的に配置されているのではなく、ランダムに配置されている。 The first fitting surface 22 is satin finished, and a plurality of protrusions 23 are formed by the satin finish. The satin finish can be formed in the casting process by forming fine irregularities in the mold for casting the first component 16 . After forming the first component 16 into a predetermined shape, post-processing can be performed by a wire brush method, a blast method, a dispersion plating method, or the like. The second fitting surface 27 is not satin-finished and does not have a projecting portion corresponding to the projecting portion 23 of the first fitting surface 22 . Therefore, the surface roughness of the first fitting surface 22 is greater than the surface roughness of the second fitting surface 27 . The surface roughness of the first fitting surface 22 is higher than the surface roughness of the second fitting surface 27 in all of the arithmetic mean roughness (Ra), maximum height (Ry), and ten-point average roughness (Rz). is also big. When the reference plane of the first fitting surface 22 is defined as the height of the lowest valley bottom, the projecting dimension of each protrusion 23 from the reference plane is random. Regarding the distribution of the plurality of protrusions 23 on the first fitting surface 22, the plurality of protrusions 23 are not regularly arranged at a constant pitch, but are randomly arranged.
　図５は、第１部品１６と第２部品２４を嵌合する前の状態をあらわす拡大断面図であり、第５図には、第１嵌合面２２における複数の突部２３の大きさや突出寸法が誇張して描かれている。第１部品１６と第２部品２４を嵌合する過程では、突部２３の頂上部が、第２嵌合面２７に摺接することによって、削られるように塑性変形する。第２嵌合面２７も、突部２３との摺接によって削られるように塑性変形する。塑性変形するときには、両部品１６，２４の間に嵌合抵抗が生じる。両嵌合面２２，２７は、両部品１６，２４の嵌合方向に対して傾斜しているので、突部２３と第２嵌合面２７との接触によって嵌合抵抗が生じるのは、両部品１６，２４の嵌合過程の途中からである。したがって、嵌合開始時から嵌合抵抗が生じる場合に比べると、嵌合時の作業性が良好である。 FIG. 5 is an enlarged cross-sectional view showing a state before the first part 16 and the second part 24 are fitted together. FIG. Dimensions are exaggerated. In the process of fitting the first part 16 and the second part 24 together, the top of the projection 23 is plastically deformed by sliding contact with the second fitting surface 27 . The second fitting surface 27 is also plastically deformed so as to be scraped by sliding contact with the protrusion 23 . A mating resistance is generated between the parts 16 and 24 when they are plastically deformed. Since both fitting surfaces 22 and 27 are inclined with respect to the fitting direction of both parts 16 and 24, the reason why fitting resistance is generated by the contact between the protrusion 23 and the second fitting surface 27 is This is from the middle of the fitting process of the parts 16 and 24 . Therefore, workability during fitting is better than when fitting resistance occurs from the start of fitting.
　図６は、第１部品１６と第２部品２４が嵌合し、第１嵌合面２２と第２嵌合面２７が近接して対向している状態をあらわす拡大断面図である。図６には、第１嵌合面２２における複数の突部２３の大きさや突出寸法が誇張して描かれている。突部２３を有しない平坦面同士を対向させて嵌合した場合、平坦面の一部のみが接触し、それ以外の広い領域では平坦面同士が非接触のままになることが懸念される。その点、本実施例１では、両部品１６，２４が嵌合して両嵌合面２２，２７が対向したときに、突出寸法の異なる複数の突部２３が、第２嵌合面２７の複数箇所に対して塑性変形した状態で接触する。したがって、第１部品１６（第１嵌合面２２）と第２部品２４（第２嵌合面２７）との接触面積が大きい。 FIG. 6 is an enlarged cross-sectional view showing a state in which the first part 16 and the second part 24 are fitted together, and the first fitting surface 22 and the second fitting surface 27 face each other closely. In FIG. 6, the sizes and projection dimensions of the plurality of protrusions 23 on the first fitting surface 22 are exaggerated. When the flat surfaces without the protrusion 23 are opposed to each other and fitted together, there is a concern that only part of the flat surfaces will come into contact with each other, and the flat surfaces will remain out of contact with each other in the other wide area. In this regard, in the first embodiment, when both parts 16 and 24 are fitted together and both fitting surfaces 22 and 27 are opposed to each other, the plurality of protrusions 23 having different projecting dimensions are formed on the second fitting surface 27. It comes into contact with multiple points in a state of being plastically deformed. Therefore, the contact area between the first part 16 (first fitting surface 22) and the second part 24 (second fitting surface 27) is large.
　本実施例１のシールド端子１は、内導体１０と、内導体１０を包囲する誘電体１１と、誘電体１１を包囲する外導体１５とを備えている。外導体１５は、互いに嵌合される複数の金属部品（第１部品１６と第２部品２４）を備えて構成されている。第１部品１６は、第２部品２４との嵌合過程において第２部品２４に摺接する第１嵌合面２２を有する。第１嵌合面２２には、複数の突部２３が形成されている。第１部品１６と第２部品２４が嵌合された状態では、複数の突部２３が塑性変形した状態で第２嵌合面２７に接触している。第１部品１６と第２部品２４を嵌合する過程では、第１嵌合面２２に形成された複数の突部２３が、第２部品２４に摺接しながら塑性変形する。この塑性変形した複数の突部２３による多点接触によって、外導体１５を構成する第１部品１６と第２部品２４を、広い面積で接触させることができる。第１部品１６と第２部品２４が広い面積で接触すると、第１嵌合面２２と第２嵌合面２７の接触面積が広く確保されてインピーダンスが低下し、第１嵌合面２２と第２嵌合面２７との間に不必要なキャパシタが生じ難くなるので、共振現象が抑制され、高速通信における通信特性の低下を防止することができる。 The shield terminal 1 of Example 1 includes an inner conductor 10 , a dielectric 11 surrounding the inner conductor 10 , and an outer conductor 15 surrounding the dielectric 11 . The outer conductor 15 includes a plurality of metal parts (first part 16 and second part 24) that are fitted together. The first part 16 has a first fitting surface 22 that comes into sliding contact with the second part 24 during the fitting process with the second part 24 . A plurality of protrusions 23 are formed on the first fitting surface 22 . When the first part 16 and the second part 24 are fitted together, the protrusions 23 are in contact with the second fitting surface 27 while being plastically deformed. In the process of fitting the first part 16 and the second part 24 together, the plurality of protrusions 23 formed on the first fitting surface 22 are plastically deformed while being in sliding contact with the second part 24 . The multipoint contact by the plurality of plastically deformed protrusions 23 allows the first part 16 and the second part 24 forming the outer conductor 15 to be brought into contact over a wide area. When the first part 16 and the second part 24 are in contact with each other over a large area, a large contact area is secured between the first fitting surface 22 and the second fitting surface 27, and the impedance decreases. Since an unnecessary capacitor is less likely to be generated between the two fitting surfaces 27, the resonance phenomenon is suppressed, and deterioration of communication characteristics in high-speed communication can be prevented.
　第２部品２４は、鋳造、鍛造又は切削によって成形されたものであり、剛性が高い。第２部品２４に形成されている第２嵌合面２７は、平坦面であるから変形し難い。第１部品１６も、鋳造、鍛造又は切削によって成形されているため剛性が高いのであるが、突部２３は、小さく突出した部位であるから、平坦状の第２嵌合面２７に比べると、剛性が比較的低い。したがって、第２嵌合面２７に突部２３が接触したときに、突部２３を確実に塑性変形させることができる。 The second part 24 is molded by casting, forging or cutting, and has high rigidity. Since the second fitting surface 27 formed on the second part 24 is a flat surface, it is difficult to deform. The first part 16 is also formed by casting, forging, or cutting, and thus has high rigidity. Relatively low stiffness. Therefore, when the protrusion 23 contacts the second fitting surface 27, the protrusion 23 can be reliably deformed plastically.
　互いに嵌合される第１部品１６と第２部品２４のうち、第１部品１６のみに複数の突部２３を形成した。この構成によれば、大多数の突部２３を塑性変形させて、第２部品２４との第２嵌合面２７に接触させることができる。第１部品１６と第２部品２４の嵌合方向に対して、第１嵌合面２２と第２嵌合面２７が斜めをなしている。この構成によれば、第１部品１６と第２部品２４の嵌合過程では、複数の突部２３が塑性変形するタイミングが分散されるので、嵌合抵抗の最大値を低減することができる。 Of the first part 16 and the second part 24 that are fitted together, only the first part 16 is provided with a plurality of protrusions 23 . According to this configuration, most of the protrusions 23 can be plastically deformed to come into contact with the second fitting surface 27 with the second component 24 . The first fitting surface 22 and the second fitting surface 27 are oblique to the fitting direction of the first part 16 and the second part 24 . According to this configuration, in the fitting process of the first part 16 and the second part 24, the timings of plastic deformation of the plurality of protrusions 23 are dispersed, so that the maximum fitting resistance can be reduced.
　複数の突部２３の突出寸法がランダムに設定されているので、両部品１６，２４の嵌合過程では、複数の突部２３が塑性変形するタイミングが分散される。したがって、突部２３の塑性変形に起因する嵌合抵抗の最大値を、低減することができる。複数の突部２３は、ワイヤブラシ法、ブラスト法、分散めっき法等によって施された梨地加工によって形成されたものであるから、所望の大きさや配置の突部２３を形成することができる。複数の突部２３は、第１嵌合面２２上においてランダムに配置されているので、精度の低いブラスト加工によって突部２３を形成することが可能である。 Since the projecting dimensions of the plurality of protrusions 23 are set at random, the timing of plastic deformation of the plurality of protrusions 23 is dispersed during the fitting process of the two parts 16 and 24 . Therefore, the maximum value of fitting resistance due to plastic deformation of the protrusion 23 can be reduced. Since the plurality of protrusions 23 are formed by satin finishing by a wire brush method, blasting method, dispersion plating method, or the like, the protrusions 23 can be formed in a desired size and arrangement. Since the plurality of projections 23 are randomly arranged on the first fitting surface 22, it is possible to form the projections 23 by blasting with low accuracy.

When the reference plane of the first fitting surface 31 is defined as the height of the lowest valley bottom, the projecting dimension of each first protrusion 32 from the reference plane is constant. When the reference plane of the second fitting surface 34 is defined as the height of the lowest valley bottom, the projection dimension of each second protrusion 35 from the reference plane is constant. The projection dimension of the first projection 32 from the reference plane and the projection dimension of the second projection 35 from the reference plane are set to be the same dimension.
　第１嵌合面３１における複数の第１突部３２の分布については、複数の第１突部３２は、一定ピッチで規則的に配置されている。第２嵌合面３４における複数の第２突部３５の分布については、複数の第２突部３５も、一定ピッチで規則的に配置されている。第１突部３２の山数ＰＰＩは、第２突部３５の山数ＰＰＩよりも少ない。山数ＰＰＩの少ない第１突部３２の頂上部は、比較的なだらかな山形をなす。これに対し、山数ＰＰＩの多い第２突部３５の頂上部は、第１突部３２に比べると尖った山形をなす。したがって、第１突部３２の強度は第２突部３５よりも大きい。 Regarding the distribution of the plurality of first protrusions 32 on the first fitting surface 31, the plurality of first protrusions 32 are regularly arranged at a constant pitch. Regarding the distribution of the plurality of second protrusions 35 on the second fitting surface 34, the plurality of second protrusions 35 are also regularly arranged at a constant pitch. The number of ridges PPI of the first protrusion 32 is less than the number of ridges PPI of the second protrusion 35 . The top portion of the first projection 32 having a small number of peaks PPI forms a relatively gentle mountain shape. On the other hand, the top portion of the second protrusion 35 having a large number of peaks PPI has a sharper peak than that of the first protrusion 32 .
