Description

本発明は、高周波信号を取り扱う機器に用いられ、同軸ケーブルに対する接続を行うために使用される同軸コネクタに係り、とくに同軸コネクタに同軸ケーブルを固定するカシメリングに関する。   The present invention relates to a coaxial connector that is used for equipment that handles high-frequency signals and is used to connect to a coaxial cable, and more particularly, to caulking that fixes the coaxial cable to the coaxial connector.

同軸コネクタに同軸ケーブルを接続するには、同軸ケーブルの端部で中心導体および外部導体を同軸コネクタの対応導体に電気的に接続し、かつ同軸ケーブルの外被および編組を同軸コネクタの円筒状部に被せた上で外周からカシメリングにより固定し、抜け止めを図っている。   To connect the coaxial cable to the coaxial connector, the center conductor and the outer conductor are electrically connected to the corresponding conductors of the coaxial connector at the end of the coaxial cable, and the coaxial cable jacket and braid are connected to the cylindrical portion of the coaxial connector. It is fixed by caulking from the outer periphery after covering it, and is intended to prevent it from coming off.

図4は、カシメリングを装着後の状態を示したものである。同軸コネクタ10に同軸ケーブル20の端部を接続し、カシメリング30を嵌装している。この場合、同軸ケーブル20の外被21および編組が同軸コネクタ10の図示しない円筒状部に被せられ、同軸ケーブルの絶縁体22の中心位置にある中心導体が同軸コネクタ10の中心導体を兼ねる構成となっている。   FIG. 4 shows a state after the caulking ring is mounted. An end of the coaxial cable 20 is connected to the coaxial connector 10 and a caulking ring 30 is fitted. In this case, the outer sheath 21 and the braid of the coaxial cable 20 are put on a cylindrical portion (not shown) of the coaxial connector 10, and the central conductor at the center position of the insulator 22 of the coaxial cable also serves as the central conductor of the coaxial connector 10. It has become.

そして、カシメリング30は、同軸コネクタ10と同軸ケーブル20とを組合わせる前に、同軸ケーブル20に通しておき、接続作業の後にカシメリング30を正しい位置に置いてかしめる。   The caulking ring 30 is passed through the coaxial cable 20 before the coaxial connector 10 and the coaxial cable 20 are combined, and the caulking ring 30 is placed in a correct position after the connection work.

図5は、図4に示したカシメリング30の正面形状を示したものである。このカシメリング30は、ほぼリング状であって、本体31の一部にカシメ用の一対の工具掛け32およびこの工具掛け32相互間のカシメ代33が設けられたものである。   FIG. 5 shows the front shape of the caulking ring 30 shown in FIG. The caulking ring 30 is substantially ring-shaped, and a part of a main body 31 is provided with a pair of caulking tool hooks 32 and caulking allowances 33 between the tool hooks 32.

カシメリング30は、このようにリング状であるから、同軸コネクタと同軸ケーブルとを接続する前に、カシメリング30を同軸ケーブルに通しておく必要がある。   Since the caulking ring 30 has a ring shape as described above, it is necessary to pass the caulking ring 30 through the coaxial cable before connecting the coaxial connector and the coaxial cable.

これを忘れると作業をやり直すことになり、また忘れなくても高所で接続作業を行う場合などは同軸ケーブルに通したカシメリングが同軸ケーブルを伝って遥か下方まで落下することもあり、作業性の面で不都合がある。   If you forget this, you will have to do the work again, and if you do not forget to connect at a high place, the caulking ring that passed through the coaxial cable may fall down along the coaxial cable. There is inconvenience in terms of.

本発明は上述の点を考慮してなされたもので、同軸コネクタを同軸ケーブルと接続した状態でも嵌装およびかしめ作業をすることができるカシメリングを提供することを目的とする。   The present invention has been made in consideration of the above-described points, and an object thereof is to provide a caulking ring that can be fitted and caulked even when the coaxial connector is connected to the coaxial cable.

上記目的達成のため、本発明では、
同軸ケーブルを同軸コネクタに接続した後、抜け落ち防止のため前記同軸ケーブルの外被の外側に嵌装して締め付けるカシメリングにおいて、中央部が平板状であり、この中央部の両側にカシメ後の外形形状と同等の半径を持ち、互いに対向するように立ち上がった一対の曲面部分を有し、カシメ後の状態で前記曲面部分の端部間に開口部を形成する程度の全長であることを特徴とするカシメリング、
を提供するものである。
In order to achieve the above object, in the present invention,
In caulking, after connecting the coaxial cable to the coaxial connector and fitting it to the outside of the outer cover of the coaxial cable to prevent it from falling off, the central part is flat, and the outer shape after crimping on both sides of this central part It has a radius equivalent to the shape, has a pair of curved surfaces that rise so as to face each other, and has a total length that forms an opening between the ends of the curved surfaces in a state after crimping. Caulking,
Is to provide.

本発明は上述のように、一部に開口部を有するため、この開口部を介して同軸ケーブルを通すことができ、次いで平板状部分を同軸ケーブルの外被の上から同軸コネクタの円筒状部を包み込むように屈曲し、さらに一対の曲面部分を同軸ケーブルの外被に密着させることにより、同軸コネクタと同軸ケーブルとを確実に抜け止め固定することができる。   As described above, since the present invention has an opening in a part thereof, the coaxial cable can be passed through the opening, and then the flat plate-like portion is formed on the outer surface of the coaxial cable from the cylindrical portion of the coaxial connector. The coaxial connector and the coaxial cable can be surely prevented from coming off and fixed by bending the cable so as to wrap the cable and further bringing the pair of curved surfaces into close contact with the outer cover of the coaxial cable.

図1(a),(b)は、本発明に係るカシメリングの一実施例を示す正面図および平面図である。このカシメリング300は、可塑性材料、例えばアルミニウム等の金属を細長く成形した板材により作製される。そして、対象とする同軸コネクタに同軸ケーブルを接続したものをワークと呼ぶと、このワークの外周長よりも若干短い長さに切断したものを成形して、本発明に係るカシメリングを構成する。   FIGS. 1 (a) and 1 (b) are a front view and a plan view showing an embodiment of caulking according to the present invention. The caulking ring 300 is made of a plate material obtained by forming a plastic material, for example, a metal such as aluminum into an elongated shape. And what connected the coaxial cable to the coaxial connector made into object is called a workpiece | work, The thing cut | disconnected to the length a little shorter than the outer periphery length of this workpiece | work is shape | molded, and the crimping ring which concerns on this invention is comprised.

まず中央部301は平板状にし、その両側に円弧状に形成された一対の曲面部分302を配する。そして、一対の曲面部分302の各基部302aで中央部分301と連なっている。   First, the central portion 301 is formed into a flat plate shape, and a pair of curved surface portions 302 formed in an arc shape are arranged on both sides thereof. The base portion 302 a of the pair of curved surface portions 302 is continuous with the central portion 301.

一対の曲面部分302は、内周面が対象とするワークの外周面に一致するように、曲率を選んで成形されている。そして、一対の曲面部分302の各端部302bの相互間は、開口部となっている。この開口部は、ワークを通すことができる程度の大きさに形成されている。   The pair of curved surface portions 302 are formed by selecting a curvature so that the inner peripheral surface coincides with the outer peripheral surface of the target workpiece. And between each end part 302b of a pair of curved surface part 302 is an opening part. The opening is formed in a size that allows the work to pass therethrough.

それには、カシメリング300を同軸ケーブルに通してからワークの位置までずらすのであれば開口部は小さめでよいし、ワークの位置で通すのであれば大きめに形成する。   For this purpose, the opening may be smaller if the caulking ring 300 is passed through the coaxial cable and then shifted to the position of the workpiece, and larger if it is passed at the position of the workpiece.

図2(a),(b)は、図1に示したカシメリング300をワークに装着する前および装着後の状態を示したものである。まず図2(a)に示すように、カシメリング300の開口部をワークに向け、この開口部にワークを通す。そして、図2(b)に示すように、カシメリング300をかしめることにより、ワークがカシメリング300の内周面に密着した状態となる。   FIGS. 2A and 2B show states before and after mounting the caulking ring 300 shown in FIG. 1 on the workpiece. First, as shown in FIG. 2 (a), the opening of the caulking ring 300 is directed to the workpiece, and the workpiece is passed through this opening. Then, as shown in FIG. 2 (b), the caulking ring 300 is caulked to bring the workpiece into close contact with the inner peripheral surface of the caulking ring 300.

このとき、カシメリング300の曲面部分302の両端部302b相互間は、一般には隙間が空いた状態となる。言い換えれば、曲面部分302相互間に隙間が空く程度の長さにカシメリング300を形成しておく方が、かしめたときのカシメ代があって作業性が良好である。したがって、十分にかしめた結果として隙間が殆どない状態になっても支障はない。   At this time, a gap is generally left between both end portions 302b of the curved surface portion 302 of the caulking ring 300. In other words, if the caulking ring 300 is formed in such a length that there is a gap between the curved surface portions 302, there is a caulking margin when caulking, and workability is better. Therefore, there is no problem even if there is almost no gap as a result of sufficient caulking.

図3(a),(b)は、本発明のもう一つの実施例をワークに装着する前および装着後の状態を示したものである。この実施例では、リングの内周面に、回り止め用の2つの突起303が設けられている。   FIGS. 3 (a) and 3 (b) show a state before and after mounting on another workpiece according to another embodiment of the present invention. In this embodiment, two protrusions 303 for preventing rotation are provided on the inner peripheral surface of the ring.

この実施例2においても、実施例1と同様、図3(a)に示すように、カシメリング300の開口部をワークに向け、この開口部にワークを通す。そして、図2(b)に示すように、カシメリング300をかしめることにより、ワークがカシメリング300の内周面に密着した状態となる。   Also in the second embodiment, as in the first embodiment, as shown in FIG. 3A, the opening portion of the caulking ring 300 is directed to the workpiece, and the workpiece is passed through the opening portion. Then, as shown in FIG. 2 (b), the caulking ring 300 is caulked to bring the workpiece into close contact with the inner peripheral surface of the caulking ring 300.

この状態で、図2と異なるのは、カシメリング300の内周面に設けた突起303が同軸ケーブルの外被に食い込んでおり、カシメリング300に周方向の大きな力が加わってもカシメリング300が回ることはない。   In this state, the difference from FIG. 2 is that the protrusion 303 provided on the inner peripheral surface of the caulking ring 300 bites into the jacket of the coaxial cable, and the caulking ring 300 is applied even when a large circumferential force is applied to the caulking ring 300. Will never turn.

カシメリング300は、その外表面に着色しておくことにより、作業時にカシメリング300の存在を認識し易くなる。そして、特定色を用いることにより装着後の確認作業がし易くなる。   By coloring the outer surface of the caulking ring 300, it becomes easy to recognize the presence of the caulking ring 300 during work. And it becomes easy to perform the confirmation work after mounting | wearing by using a specific color.
