Description

本発明は、同軸コネクタ用の内導体端子、この内導体端子を並列に横連鎖させてなる連鎖端子、及び、同軸ケーブルと内導体端子との圧着接続方法に関する。   The present invention relates to an inner conductor terminal for a coaxial connector, a chain terminal formed by laterally chaining the inner conductor terminals in parallel, and a method for crimping and connecting a coaxial cable and an inner conductor terminal.

内部導体として芯線を有し、且つ外部導体として編組を有する同軸ケーブルの端末に同軸コネクタを設ける場合、同軸ケーブルの芯線と同軸コネクタの内導体端子との圧着接続部分のインピーダンスを、できるだけ同軸ケーブルのインピーダンスに近づけることが重要になっている。   When a coaxial connector is provided at the end of a coaxial cable having a core wire as an inner conductor and a braid as an outer conductor, the impedance of the crimp connection portion between the core wire of the coaxial cable and the inner conductor terminal of the coaxial connector is set as much as possible of the coaxial cable. It is important to bring it close to impedance.

下記特許文献１の開示技術にあっては、図７に示す如く、同軸ケーブル１の芯線２と、同軸コネクタを構成する内導体端子３とを圧着接続し、この後、圧着接続部分４に、内側に導電層を有する熱収縮成形品５を挿入し、そして、この熱収縮成形品５を加熱収縮させることによりインピーダンス整合部６を形成するような工夫がなされている。   In the disclosed technology of Patent Document 1 below, as shown in FIG. 7, the core wire 2 of the coaxial cable 1 and the inner conductor terminal 3 constituting the coaxial connector are crimped and connected to the crimping connection portion 4. A device is devised in which an impedance matching portion 6 is formed by inserting a heat-shrinkable molded product 5 having a conductive layer inside and then heat-shrinking the heat-shrinkable molded product 5.

ここで、端子の一般的な圧着接続に関して説明をする。従来の端子の圧着接続は、例えば下記特許文献２に開示されている。図８及び図９において、端子圧着装置１１は、シャーブレード１２によって連鎖端子１３のキャリア１４を切断するような構成になっている。シャーブレード１２は、バネ１５により上向きに付勢されている。シャーブレード１２には、キャリア１４を挿通するための水平方向の溝１６が形成されている。溝１６の上縁には、刃部１７、１８が形成されている。図１０において、連鎖端子１３は、複数の端子１９の圧着片２０側の後端がキャリア１４に連結されており、複数の端子１９が並列に横連鎖するような状態で形成されている。   Here, a general crimp connection of terminals will be described. Conventional crimp connection of terminals is disclosed in, for example, Patent Document 2 below. 8 and 9, the terminal crimping device 11 is configured to cut the carrier 14 of the chain terminal 13 by the shear blade 12. The shear blade 12 is biased upward by a spring 15. The shear blade 12 is formed with a horizontal groove 16 through which the carrier 14 is inserted. Blade portions 17 and 18 are formed on the upper edge of the groove 16. In FIG. 10, the chain terminal 13 is formed such that the rear ends of the plurality of terminals 19 on the side of the crimping piece 20 are connected to the carrier 14 and the plurality of terminals 19 are laterally chained in parallel.

上記構成において、端子圧着装置１１のアンビル２１とクリンパ２２との間で端子１９を電線に圧着接続させると同時に、シャーブレード１２を押圧降下させ、シャーブレード１２の正面側の刃部１７とクリンパ２２側の固定刃２３とでキャリア１４の連結部２４を剪断すると、端子１９がキャリア１４から分離する。この時、シャーブレード１２の側面側の刃部１８と側方の固定刃２５とでキャリア１４がチップ状に切断される（チップカス２６参照）。連鎖端子１３は、キャリア１４の孔２７に送り爪２８を係合させることによって送り出されるようになっている。
特開２００１−１８５３０２号公報 特開平８−１６２２４８号公報 In the above-described configuration, the terminal 19 is crimped and connected to the electric wire between the anvil 21 and the crimper 22 of the terminal crimping device 11, and at the same time, the shear blade 12 is pressed down and the blade portion 17 on the front side of the shear blade 12 and the crimper 22 are pressed. When the connecting portion 24 of the carrier 14 is sheared with the fixed blade 23 on the side, the terminal 19 is separated from the carrier 14. At this time, the carrier 14 is cut into chips by the side blades 18 and the side fixed blades 25 of the shear blade 12 (see the chip chip 26). The chain terminal 13 is fed out by engaging a feed claw 28 with the hole 27 of the carrier 14.

特許文献１の開示技術にあっては、熱収縮成形品５が別部品で必要になり、また、熱収縮成形品５は内側に導電層を有して熱収縮する構造を必須とすることから、これらがコスト高の要因となっている。また、熱収縮成形品５を挿入する工程と、加熱収縮させる工程とを必要とすることから、工数面や装置構成面においても影響を来している。さらに、内導体端子３の先端側（相手側端子との接続側）を通過させることができるだけの大きさに熱収縮成形品５を形成する必要があることから、熱収縮成形品５は収縮前の状態が比較的大きなものとなっている。   In the disclosed technique of Patent Document 1, the heat shrink molded product 5 is required as a separate part, and the heat shrink molded product 5 has a conductive layer on the inside and requires a heat shrink structure. These are high cost factors. Moreover, since the process of inserting the heat-shrink molded product 5 and the process of heat-shrinking are required, the man-hours and the apparatus configuration are also affected. Furthermore, since it is necessary to form the heat-shrinkable molded product 5 in such a size that it can pass through the tip side of the inner conductor terminal 3 (connection side with the counterpart terminal), the heat-shrinkable molded product 5 is not shrunk. The state is relatively large.

本発明は、上記した事情に鑑みてなされたもので、インピーダンス整合に好適な構造を有する内導体端子、連鎖端子、及び、同軸ケーブルと内導体端子との圧着接続方法を提供することを課題とする。   The present invention has been made in view of the above circumstances, and it is an object to provide an inner conductor terminal having a structure suitable for impedance matching, a chain terminal, and a method for crimping and connecting a coaxial cable and an inner conductor terminal. To do.

上記課題を解決するためになされた請求項１記載の本発明の内導体端子は、同軸ケーブルの芯線に圧着接続する部分としての芯線圧着部を有し、圧着接続後の前記芯線圧着部にはインピーダンス整合部を設ける同軸コネクタ用の内導体端子において、前記インピーダンス整合部を、連鎖端子におけるキャリアの一部を切り取り曲げ加工を施して後付けする端子フェルールとすることを特徴としている。   The inner conductor terminal of the present invention according to claim 1, which has been made to solve the above problems, has a core wire crimping portion as a portion to be crimped and connected to a core wire of a coaxial cable, and the core wire crimping portion after the crimping connection has An inner conductor terminal for a coaxial connector provided with an impedance matching portion is characterized in that the impedance matching portion is a terminal ferrule that is retrofitted by cutting and bending a part of a carrier in a chain terminal.

このような特徴を有する本発明によれば、キャリアを利用して端子フェルールを形成し、この端子フェルールを圧着接続後の芯線圧着部に曲げ加工によって後付けする。端子フェルールは内導体端子に対して別部品になるものの、これらは同じ連鎖端子に形成されることから、圧着接続後の芯線圧着部に対するインピーダンス整合部の形成は容易となる。   According to the present invention having such a feature, a terminal ferrule is formed using a carrier, and this terminal ferrule is retrofitted to the core wire crimping portion after crimping connection. Although the terminal ferrule is a separate component with respect to the inner conductor terminal, since these are formed on the same chain terminal, it is easy to form the impedance matching portion for the core crimping portion after crimping connection.

上記課題を解決するためになされた請求項２記載の本発明の連鎖端子は、内導体端子の芯線圧着部側をキャリアに連結して前記内導体端子を並列に横連鎖させてなる連鎖端子において、前記キャリアに、圧着接続後の前記芯線圧着部に対しインピーダンス整合部として後付けするための端子フェルールを形成することを特徴としている。   The chain terminal of the present invention according to claim 2, which has been made to solve the above-mentioned problem, is a chain terminal in which the core conductor crimping part side of the inner conductor terminal is connected to a carrier and the inner conductor terminals are laterally chained in parallel. The terminal ferrule for retrofitting as an impedance matching part with respect to the said core wire crimping part after crimping connection is formed in the said carrier.

このような特徴を有する本発明によれば、内導体端子と端子フェルールとを有する連鎖端子になる。連鎖端子は、キャリアに端子フェルールを形成する分だけ歩留まりが向上する。端子フェルールは、内導体端子の近くに形成されることから、圧着接続後の芯線圧着部に対するインピーダンス整合部の形成は容易となる。端子フェルールは、内導体端子に対し別々に部品管理されるものでなく、従って、専用の保管スペースは不要である。   According to the present invention having such characteristics, a chain terminal having an inner conductor terminal and a terminal ferrule is obtained. The yield of the chain terminal is improved by the amount of forming the terminal ferrule on the carrier. Since the terminal ferrule is formed near the inner conductor terminal, it is easy to form the impedance matching portion with respect to the core wire crimping portion after crimping connection. The terminal ferrule is not separately managed with respect to the inner conductor terminal, and therefore a dedicated storage space is not required.

上記課題を解決するためになされた請求項３記載の本発明の同軸ケーブルと内導体端子との圧着接続方法は、アンビルと、クリンパと、上向きに付勢されるシャーブレードとを含み、該シャーブレードは、水平方向のキャリア用溝を有するシャーブレード本体と、上下一対の曲げ型とを備え、前記シャーブレード本体には、この上面と前記キャリア用溝とを連通し且つ下側の前記曲げ型を収容するための穴部を形成する一方、上側の前記曲げ型を前記穴部の上方に配置し、このような構成の端子圧着装置を用いて行う工程として、連鎖端子における内導体端子の芯線圧着部と、同軸ケーブルの芯線とを前記アンビル及び前記クリンパによって圧着接続すると同時に、前記シャーブレード本体を降下させて前記内導体端子とキャリアとの連結部を切断し、且つ前記キャリア用溝に前記キャリアを残す第一工程と、圧着接続後の前記内導体端子を前記シャーブレード本体の前記上面に移動させるとともに、前記芯線圧着部を前記穴部の位置にセットする第二工程と、前記シャーブレード本体を降下させて前記キャリアに予め形成した端子フェルールを切り取ると同時に、上下一対の前記曲げ型によって曲げ加工を施しつつ前記端子フェルールを前記芯線圧着部に対し後付けする第三工程と、を含むことを特徴としている。   A method for crimping and connecting a coaxial cable and an inner conductor terminal according to claim 3 of the present invention made to solve the above-described problem includes an anvil, a crimper, and a shear blade biased upward. The blade includes a shear blade body having a horizontal carrier groove and a pair of upper and lower bending dies. The shear blade body communicates with the upper surface and the carrier groove, and the lower bending die. The core wire of the inner conductor terminal in the chain terminal is a step that is performed using the terminal crimping device having such a configuration in which the upper bending mold is disposed above the hole portion while the hole portion for accommodating the inner terminal is formed. The crimping portion and the coaxial cable core wire are crimped and connected by the anvil and the crimper, and at the same time, the shear blade body is lowered to connect the inner conductor terminal and the carrier. The first step of cutting and leaving the carrier in the carrier groove, and moving the inner conductor terminal after crimping connection to the upper surface of the shear blade main body, the core wire crimping portion at the position of the hole A second step of setting, and lowering the shear blade main body to cut out the terminal ferrule formed in advance on the carrier, and at the same time, bending the terminal ferrule with respect to the core wire crimping part while bending with the pair of upper and lower bending molds And a third step to be retrofitted.

このような特徴を有する本発明によれば、内導体端子の芯線圧着部と同軸ケーブルの芯線とを圧着接続し、この後にシャーブレード本体の上面において、シャーブレードの構成により、端子フェルールを圧着接続後の芯線圧着部に対し曲げ加工によって後付けする。本発明によれば、連鎖端子のキャリアに端子フェルールを形成するとともに、端子圧着装置のシャーブレードの構成及び構造を一般的な装置に対し若干変更するだけで、圧着接続後の芯線圧着部に対するインピーダンス整合部の形成が容易となる。   According to the present invention having such a feature, the core wire crimping portion of the inner conductor terminal and the core wire of the coaxial cable are crimped and connected, and then the terminal ferrule is crimped and connected on the upper surface of the shear blade body by the configuration of the shear blade. It is retrofitted to the subsequent core wire crimping part by bending. According to the present invention, the terminal ferrule is formed on the carrier of the chain terminal, and the impedance of the core wire crimping portion after crimping connection is changed by slightly changing the configuration and structure of the shear blade of the terminal crimping device with respect to a general device. Formation of the alignment portion is facilitated.

本発明によれば、コスト高にならず、むしろコスト低減に寄与し、工数面や装置構成面においても良好であることから、インピーダンス整合に好適な構造を有する内導体端子、連鎖端子、及び、同軸ケーブルと内導体端子との圧着接続方法を提供することができるという効果を奏する。   According to the present invention, it does not increase the cost, but rather contributes to cost reduction, and is good in terms of man-hours and equipment configuration, so that the inner conductor terminal having a structure suitable for impedance matching, the chain terminal, and There is an effect that it is possible to provide a crimping connection method between the coaxial cable and the inner conductor terminal.

端子圧着装置を用いて行う第一工程としては、連鎖端子４２における内導体端子３２の芯線圧着部４１と、同軸ケーブル３１の芯線３５とをアンビル６２及びクリンパ６３によって圧着接続することを行う。また、これと同時にシャーブレード本体５２をシャーブレード押圧部６１によって降下させて内導体端子３２とキャリア４３との連結部４４を切断することを行う。この時、キャリア用溝５６には、キャリア４３が残るものとする（図３（ａ）参照）。   As a first step performed using the terminal crimping apparatus, the core wire crimping portion 41 of the inner conductor terminal 32 in the chain terminal 42 and the core wire 35 of the coaxial cable 31 are crimped and connected by the anvil 62 and the crimper 63. At the same time, the shear blade body 52 is lowered by the shear blade pressing portion 61 to cut the connecting portion 44 between the inner conductor terminal 32 and the carrier 43. At this time, it is assumed that the carrier 43 remains in the carrier groove 56 (see FIG. 3A).

第二工程としては、圧着接続後の内導体端子３２をシャーブレード本体５２の上面５９側に移動させるとともに、芯線圧着部４１を穴部６０の位置にセットすることを行う（図３（ｂ）参照）。   As the second step, the inner conductor terminal 32 after the crimping connection is moved to the upper surface 59 side of the shear blade body 52, and the core wire crimping portion 41 is set at the position of the hole 60 (FIG. 3B). reference).

第三工程としては、シャーブレード本体５２をシャーブレード押圧部６１によって降下させてキャリア４３の端子フェルール３４（図４参照）を切り取ると同時に、下側の曲げ型５３と上側の曲げ型５４とによって曲げ加工を施しつつ端子フェルール３４を芯線圧着部４１に対して後付けすることを行う（図４ないし図６参照。後述する）。これにより、図１（ａ）に示す如く端子フェルール３４を後付けした状態の内導体端子３２が同軸ケーブル３１の端末に設けられる。   As a third step, the shear blade main body 52 is lowered by the shear blade pressing portion 61 to cut out the terminal ferrule 34 (see FIG. 4) of the carrier 43, and at the same time, the lower bending die 53 and the upper bending die 54 are used. The terminal ferrule 34 is retrofitted with respect to the core wire crimping portion 41 while performing bending (see FIGS. 4 to 6, which will be described later). Thereby, the inner conductor terminal 32 with the terminal ferrule 34 retrofitted as shown in FIG. 1A is provided at the end of the coaxial cable 31.

図４において、端子フェルール３４の下側には、下側の曲げ型５３が配置され、図３（ｂ）及び図５に示す如くシャーブレード本体５２が降下すると、端子フェルール３４はこの下側から下側の曲げ型５３によって曲げ加工が施され、そして、図６に示す如くシャーブレード本体５２における上面５９の位置で上側の曲げ型５４（及び下側の曲げ型５３）により更に曲げ加工が施される。これにより、端子フェルール３４が巻き付くような状態で後付けされる。   In FIG. 4, a lower bending die 53 is disposed below the terminal ferrule 34. When the shear blade body 52 is lowered as shown in FIGS. 3B and 5, the terminal ferrule 34 is moved from the lower side. Bending is performed by the lower bending die 53, and further bending is performed by the upper bending die 54 (and the lower bending die 53) at the position of the upper surface 59 in the shear blade body 52 as shown in FIG. Is done. Thus, the terminal ferrule 34 is retrofitted in a state where it is wound.

以上、図１ないし図６を参照しながら説明してきたように、本発明によれば、連鎖端子４２のキャリア４３を利用して端子フェルール３４を形成し、この端子フェルール３４を圧着接続後の芯線圧着部４１（圧着接続部分３３）に曲げ加工によって後付けする構造及び方法であることから、インピーダンス整合部の形成は従来よりも格段に容易となる。また、連鎖端子４２における内導体端子３２の近傍に端子フェルール３４を形成する構造であることから、この配置面でもインピーダンス整合部の形成は従来よりも格段に容易となる。連鎖端子４２は、キャリア４３に端子フェルール３４を形成する分だけ歩留まりが向上する。   As described above with reference to FIGS. 1 to 6, according to the present invention, the terminal ferrule 34 is formed using the carrier 43 of the chain terminal 42, and the core wire after the terminal ferrule 34 is crimped and connected. Since the crimping portion 41 (crimp connection portion 33) has a structure and a method that are retrofitted by bending, the formation of the impedance matching portion is significantly easier than before. In addition, since the terminal ferrule 34 is formed in the vicinity of the inner conductor terminal 32 in the chain terminal 42, the impedance matching portion can be formed much easier than before in this arrangement surface. The yield of the chain terminal 42 is improved by the amount that the terminal ferrule 34 is formed on the carrier 43.

従って、本発明によればインピーダンス整合に好適な構造を有する内導体端子３２、連鎖端子４２、及び、同軸ケーブル３１と内導体端子３２との圧着接続方法を提供することができるという効果を奏する。   Therefore, according to the present invention, it is possible to provide an inner conductor terminal 32, a chain terminal 42, and a crimping connection method between the coaxial cable 31 and the inner conductor terminal 32 having a structure suitable for impedance matching.

本発明は本発明の主旨を変えない範囲で種々変更実施可能なことは勿論である。   It goes without saying that the present invention can be variously modified without departing from the spirit of the present invention.
