【考案の実施の形態】[Embodiment of the invention]

以下、本考案の実施例を図面を参照して説明する。図1において、ベース1は 金属製であり、中央部の長手方向に3個の貫通孔4が穿孔されていて、各貫通孔 4の中心線上で固定端子3を貫通配置するようになっている。各固定端子3と各 貫通孔4の内周面との間には絶縁物5を充填している。隣接する各一対の固定端 子3の間には夫々カード8が平行移動自在に配置され、各カード8に導電性でバ ネ性の可動接触片9が保持されている。各可動接触片9は夫々1枚ものでカード 8と一体成形され、固定端子3の側面に接触することによって、中央部の固定端 子3と各端の固定端子3との間を各可動接触片9を介して夫々接続するようにな っている。固定端子3の一部と可動接触片9とはベース1と金属製のカバー2と により覆われる。すなわち、カバー2は下面に凹所10が形成されており、この 凹所10内に固定端子3の一部と可動接触片9とを収納するように、カバー2が ベース1に結合される。カバー2には長孔11が穿孔してあって、この長孔11 にカード8を挿通させている。また、可動接触片9の先端部に対応したカバー2 の内側には夫々アース接点12が形成されていて、アース接点12と導通したア ース端子13をベース1の下面より突出させている。尚、カバー2の上にはカー ド8を駆動する電磁石部6(図2参照)が配置される。両カード8が電磁石部6 により図1(a)の上下方向に駆動されると各一対の固定端子3間が夫々開閉さ れる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a base 1 is made of metal, and three through holes 4 are drilled in a longitudinal direction of a central portion, and the fixed terminal 3 is arranged to penetrate on a center line of each through hole 4. . An insulator 5 is filled between each fixed terminal 3 and the inner peripheral surface of each through hole 4. A card 8 is arranged between each pair of adjacent fixed terminals 3 so as to be freely movable in parallel, and each card 8 holds a movable contact piece 9 that is conductive and springy. Each of the movable contact pieces 9 is integrally formed with the card 8 by a single piece, and comes into contact with the side surface of the fixed terminal 3 so that the movable contact between the fixed terminal 3 at the center portion and the fixed terminal 3 at each end is formed. Each is connected via a piece 9. A part of the fixed terminal 3 and the movable contact piece 9 are covered by the base 1 and the metal cover 2. That is, the cover 2 has a recess 10 formed on the lower surface, and the cover 2 is coupled to the base 1 so that a part of the fixed terminal 3 and the movable contact piece 9 are accommodated in the recess 10. A long hole 11 is perforated in the cover 2, and the card 8 is inserted through the long hole 11. Ground contacts 12 are formed on the inside of the cover 2 corresponding to the tips of the movable contact pieces 9, and ground terminals 13 electrically connected to the ground contacts 12 protrude from the lower surface of the base 1. An electromagnet section 6 (see FIG. 2) for driving a card 8 is disposed on the cover 2. When both the cards 8 are driven by the electromagnet unit 6 in the vertical direction in FIG.

【0007】 金属製のベース1と固定端子3との絶縁を図る絶縁物5にはフッ素樹脂を用い る。フッ素樹脂は、誘電率が低く(誘電率ε=2〜3)、誘電正接が小さく、耐 熱性が高いという特性を有している。貫通孔4に対応する部位における特性イン ピーダンスZ0 は、数1で表される。The insulator 5 that insulates the metal base 1 from the fixed terminal 3 is made of a fluorine resin. Fluororesins have characteristics of a low dielectric constant (dielectric constant ε = 2 to 3), a small dielectric loss tangent, and a high heat resistance. The characteristic impedance Z 0 at a portion corresponding to the through hole 4 is expressed by Expression 1.

【0008】[0008]

【数1】 (Equation 1)

【0009】 ここで、図1(b)に示すように、D1 は固定端子3の外径、D2 は貫通孔4の 内径、εは絶縁物5の誘電率である。特性インピーダンスZ0 を数1のような簡 単な式で表すことができるのは、固定端子3が断面円形で一定の直径を有すると ともに貫通孔4が断面円形で一定の直径を有し、しかも固定端子3が貫通孔4に その中心線上で挿通されているからである。数1から明らかなように絶縁物5の 誘電率εが小さいほど特性インピーダンスZ0 が大きくなる。また、固定端子3 はプリント板への実装性により上限が規定され強度により下限が規定されるから 一定値とみなすことができるが、貫通孔4は固定端子3よりも内径D2 が大きけ ればよく、数1によれば内径D2 が大きいほど特性インピーダンスZ0 が大きく なることがわかる。つまり、特性インピーダンスZ0 が一定であるとすれば、絶 縁物5の誘電率εが小さいほど貫通孔4の内径D2 を小さくすることが可能にな る。したがって、低誘電率であるフッ素樹脂を絶縁物5として用いることにより 貫通孔4の内径D2 を小さくすることができ、結果的に固定端子3間の距離を小 さくすることが可能になる。このことは、挿入損失の低下につながる。しかも、 フッ素樹脂は絶縁材料として一般に用いられているPBT(ポリブチレンテレフ タレート)などに比較して誘電正接が小さいから、この点からも挿入損失を小さ くすることができる。Here, as shown in FIG. 1B, D 1 is the outer diameter of the fixed terminal 3, D 2 is the inner diameter of the through hole 4, and ε is the dielectric constant of the insulator 5. The characteristic impedance Z 0 can be expressed by a simple expression such as Equation 1 because the fixed terminal 3 has a constant diameter with a circular cross section and the through hole 4 has a constant diameter with a circular cross section. Moreover, the fixed terminal 3 is inserted through the through hole 4 on the center line thereof. As is clear from Equation 1, the characteristic impedance Z 0 increases as the dielectric constant ε of the insulator 5 decreases. The fixed terminal 3 can be regarded as a fixed value because the upper limit is defined by the mountability on the printed board and the lower limit is defined by the strength, but the through hole 4 has an inner diameter D 2 larger than the fixed terminal 3. Equation 1 shows that the characteristic impedance Z 0 increases as the inner diameter D 2 increases. That is, assuming that the characteristic impedance Z 0 is constant, the smaller the dielectric constant ε of the insulator 5, the smaller the inner diameter D 2 of the through hole 4 becomes. Accordingly, the fluorine resin is a low dielectric constant can be reduced inner diameter D 2 of the through-hole 4 by using as the insulator 5, consequently becomes the distance between the fixed terminal 3 can be small fence. This leads to lower insertion loss. In addition, since the fluororesin has a smaller dielectric loss tangent than PBT (polybutylene terephthalate) generally used as an insulating material, the insertion loss can be reduced from this point as well.

【0010】 また、図1により明らかなように、貫通孔4の両端間の距離(固定端子3の長 手方向における絶縁物5の厚み)に対して固定端子3と可動接触片9との接触部 位から絶縁物5までの距離は十分に小さく設定してあり、固定端子3において可 動接触片9との接触部位と絶縁物5との間の部位(つまり、空中に露出している 部位)の特性インピーダンスへの影響を小さくすることができる。このことは、 数1による設計値にほぼ一致した特性インピーダンスを得ることができるという ことであり、特性インピーダンスの設定が容易になる。Also, as is clear from FIG. 1, the distance between the fixed terminal 3 and the movable contact piece 9 with respect to the distance between both ends of the through hole 4 (the thickness of the insulator 5 in the longitudinal direction of the fixed terminal 3). The distance from the portion to the insulator 5 is set to be sufficiently small, and a portion of the fixed terminal 3 between the contact portion with the movable contact piece 9 and the insulator 5 (that is, a portion exposed in the air). ) Can be less affected by the characteristic impedance. This means that it is possible to obtain a characteristic impedance that substantially matches the design value according to Equation 1, and it is easy to set the characteristic impedance.
