The present invention relates to a connector terminal with a shielded wire.

図６は従来のシールド電線付きコネクタ端子の分解斜視図であり、図７は図６に示したシールド電線付きコネクタ端子の組立状態の縦断面図である。
なお、ここに示したシールド電線付きコネクタ端子１０１は、下記特許文献１に開示された構成のものであり、またシールド電線の一種である同軸ケーブル１を相手方端子（不図示）にコネクタ接続するために、この同軸ケーブル１の一端部に端子本体１０３が接続された構成になっている。 6 is an exploded perspective view of a conventional connector terminal with a shielded wire, and FIG. 7 is a longitudinal sectional view of the assembled connector terminal with a shielded wire shown in FIG.
In addition, the connector terminal 101 with a shielded electric wire shown here has a configuration disclosed in Patent Document 1 below, and is used to connect the coaxial cable 1 which is a kind of shielded electric wire to a counterpart terminal (not shown). In addition, the terminal main body 103 is connected to one end of the coaxial cable 1.

同軸ケーブル１は、図６に示すように、内部導体である中心導体（芯線）１１と、この中心導体１１の外周面を包囲しながらこの中心導体１１の長手方向に延長する絶縁物（内部被覆）１３と、シールド部材としてこの絶縁物１３の外周面を包囲しながらその長手方向に延長する外部導体１５と、この外部導体１５の外周面を包囲しながらその長手方向に延長する絶縁外皮（外部被覆）１７と、を備えて構成されている。そして、その長手方向の一端部（先端部）において、中心導体１１、絶縁物１３、外部導体１５、及び絶縁外皮１７のそれぞれの一端部が露出されている。 As shown in FIG. 6, the coaxial cable 1 includes a center conductor (core wire) 11 that is an inner conductor and an insulator (inner covering) that extends in the longitudinal direction of the center conductor 11 while surrounding the outer peripheral surface of the center conductor 11. ) 13, an outer conductor 15 extending in the longitudinal direction while surrounding the outer peripheral surface of the insulator 13 as a shield member, and an insulating sheath (external) extending in the longitudinal direction while surrounding the outer peripheral surface of the outer conductor 15 Coating) 17. Then, at one end portion (tip portion) in the longitudinal direction, one end portions of the center conductor 11, the insulator 13, the outer conductor 15, and the insulating outer shell 17 are exposed.

一方、端子本体１０３は、図６に示すように、一端部に中心導体加締部１１１ａを有して同軸ケーブル１の一端部で中心導体１１に電気的に接続された、相手方端子に中心導体１１を電気的に接続するための導通性金属製の中心導体導通端子（芯線導通端子：一般的に「中心コンタクト」と呼ばれる）１１１と、この中心導体導通端子１１１が中心導体１１に電気的に接続した状態でこの中心導体１１と伴に貫通し且つ係止される貫通孔１１５ａが形成された絶縁部材（絶縁部材：例えば、ポリエチレン等による発泡誘電体）１１５と、この絶縁部材１１５に外嵌し且つ中心導体導通端子１１１の周囲を包囲しながらこの中心導体導通端子１１１を、絶縁部材１１５を介して支持する円筒部１１３ｃが一端部に設けられ、同軸ケーブル１の一端部で外部導体１５を加締めるための外部導体加締部（シールド部材加締部）１１３ａ及び絶縁外皮１７を加締めるための絶縁外皮加締部（外部被覆加締部）１１３ｂが他端部で連設され、且つこの外部導体１５に電気的に接続される導電性金属製のシールド端子１１３と、備えている。
なお、同軸ケーブル１の一端部で露出された中心導体１１と中心導体導通端子１１１との接続部、即ち中心導体１１の加締め状態にある中心導体加締部１１１ａは、その外周を熱収縮性チューブ１１７により密着状態で覆われており、また絶縁部材１１５により、シールド端子１１３内に挿入された中心導体導通端子１１１とシールド端子１１３の間に所定の誘電率が確保されることになる。 On the other hand, as shown in FIG. 6, the terminal main body 103 has a central conductor caulking portion 111 a at one end and is electrically connected to the central conductor 11 at one end of the coaxial cable 1. A conductive metal center conductor conducting terminal (core wire conducting terminal: generally referred to as “center contact”) 111 and the center conductor conducting terminal 111 are electrically connected to the center conductor 11. An insulating member (insulating member: foamed dielectric material made of polyethylene or the like) 115 formed with a through-hole 115a penetrating and locked with the central conductor 11 in a connected state, and externally fitted to the insulating member 115 In addition, a cylindrical portion 113c that supports the central conductor conduction terminal 111 via the insulating member 115 while surrounding the circumference of the central conductor conduction terminal 111 is provided at one end. The outer conductor caulking part (shield member caulking part) 113a for caulking the outer conductor 15 at the part and the insulating outer skin caulking part (outer sheath caulking part) 113b for caulking the insulating outer skin 17 are provided at the other end. A shield terminal 113 made of a conductive metal that is connected to and electrically connected to the outer conductor 15 is provided.
It should be noted that the connection portion between the center conductor 11 and the center conductor conduction terminal 111 exposed at one end of the coaxial cable 1, that is, the center conductor crimping portion 111 a in the crimped state of the center conductor 11 has a heat shrinkable outer periphery. The tube 117 is covered in close contact, and the insulating member 115 secures a predetermined dielectric constant between the central conductor conducting terminal 111 inserted into the shield terminal 113 and the shield terminal 113.

このとき、シールド端子１１３の円筒部１１３ｃに装着される絶縁部材１１５は、円筒部１１３ｃから脱落しないように、円筒部１１３ｃ内に確実に固定される必要がある。
そこで、従来では、絶縁部材１１５の外周部に、前方（図中左方）への移動を規制するための段部１１５ｂ（図６参照）と、後方（図中右方）への移動を規制するための段部１１５ｃ（図７参照）とが設けられおり、これに対応して、円筒部１１３ｃの内周面には、それぞれの段部１１５ｂ，１１５ｃに係止して絶縁部材１１５の移動を規制するための係止片１１３ｄが設けられている。
なお、図７は、円筒部１１３ｃの内周面に設けられた係止片１１３ｄが、絶縁部材１１５の段部１１５ｃに係止して、絶縁部材１１５の後方への移動が規制されている状態を示している。 At this time, the insulating member 115 attached to the cylindrical portion 113c of the shield terminal 113 needs to be securely fixed in the cylindrical portion 113c so as not to drop off from the cylindrical portion 113c.
Therefore, conventionally, a step 115b (see FIG. 6) for restricting forward movement (leftward in the figure) and a backward movement (rightward in the figure) are restricted at the outer peripheral portion of the insulating member 115. Correspondingly, a step 115c (see FIG. 7) is provided. Correspondingly, the inner peripheral surface of the cylindrical portion 113c is engaged with the respective steps 115b and 115c to move the insulating member 115. 113d for restricting is provided.
7 shows a state in which the locking piece 113d provided on the inner peripheral surface of the cylindrical portion 113c is locked to the step portion 115c of the insulating member 115, and the backward movement of the insulating member 115 is restricted. Is shown.

しかしながら、シールド端子１１３内での絶縁部材１１５の移動を規制するために、絶縁部材１１５の外周に段部１１５ｂ，１１５ｃを形成し、加えて、シールド端子１１３の内周面に段部１１５ｂ，１１５ｃに対応した係止片１１３ｄが設けられた従来のシールド電線付きコネクタ端子１０１では、この段部１１５ｂ，１１５ｃ、及び係止片１１３ｄがインピーダンスの乱れを招き、これにより、接続される同軸ケーブル１の高周波特性を低下させてしまっていた。
さらに、段部１１５ｂ，１１５ｃ、及び係止片１１３ｄ等の形成のために、シールド端子１１３、及び絶縁部材１１５の構造が複雑化し、これらの部品の製造コストの増大を招いていた。 However, in order to restrict the movement of the insulating member 115 in the shield terminal 113, the step portions 115 b and 115 c are formed on the outer periphery of the insulating member 115, and in addition, the step portions 115 b and 115 c are formed on the inner peripheral surface of the shield terminal 113. In the conventional connector terminal 101 with a shielded wire provided with the locking piece 113d corresponding to the above, the step portions 115b and 115c and the locking piece 113d cause the disturbance of the impedance, thereby causing the coaxial cable 1 to be connected. The high frequency characteristics have been degraded.
Furthermore, the formation of the stepped portions 115b and 115c, the locking pieces 113d, and the like complicate the structures of the shield terminal 113 and the insulating member 115, leading to an increase in manufacturing costs of these components.

本発明は、前述した課題に鑑みてなされたものであり、その目的は、コネクタ端子の内部でのインピーダンスの乱れを無くして、高周波特性を向上させることができ、加えて、シールド端子及び絶縁部材の構造の簡素化を図って、これらの部品の製造コストを低減することのできるシールド電線付きコネクタ端子、並びにシールド電線付きコネクタ端子の製造方法を提供することにある。 The present invention has been made in view of the above-described problems, and an object of the present invention is to improve the high-frequency characteristics by eliminating the disturbance of impedance inside the connector terminal, and in addition to the shield terminal and the insulating member. It is intended to provide a method of manufacturing a connector terminal with a shielded wire and a connector terminal with a shielded wire, which can reduce the manufacturing cost of these components.

上記（１）の構成によれば、長手方向の、円筒部の中間部に、一対のスリットが円筒部の周方向に沿って且つ長手方向で互いに離間するように形成され、一対のスリットを長手方向に沿って架け渡すように切れ目部が形成され、一対のスリット及び切れ目部により円筒部の中間部に絶縁部材加締部が形成される。これにより、円筒部に設けられた絶縁部材加締部が、所定の工具により円筒部の内側に曲げられ、絶縁部材の外周面の一部に食い込む。このため、絶縁部材加締部は、円筒部の内側に曲げられており、シールド端子の円筒部に装着される絶縁部材は、円筒部内に固定されることになる。即ち、絶縁部材自体には、円筒部からの抜け止めを防止するための段部を形成する必要なく、加えて、シールド端子の円筒部においても、その内周面に係止片等を突出形成する必要がない。このため、絶縁部材の外周面に段部が不要になり、また、シールド端子の円筒部の内周面に抜け止めを防止するため係止片を突設する必要もなくなり、これらの部品を径方向における形状変化の少ない簡素な構造にすることができるため、シールド端子の内部での誘電体や導体の径方向における形状変化に起因するインピーダンスの乱れを防止でき、高周波特性の向上を図ることができる。また、シールド端子及び絶縁部材を簡素な構造にできるため、これらの部品の加工や成形が容易になり、これらの部品の製造コストを低減させることもできる。
上記（２）の構成によれば、シールド端子は、所定の形状を有した板材を内側に曲げることにより形成されており、切れ目部は、この板材の両縁部に位置する側面が対峙するように配置されることで形成されている。このため、切れ目部を新たに形成する必要がなくなり、即ち、プレス加工によりシールド端子を成形して、このとき形成される合わせ目（両側面が対峙配置される部分）を切れ目部として利用して、この合わせ目に交差するように一対のスリットを形成するだけで、容易に絶縁部材加締部を形成することができる。これにより、製造コストを低減することができる。
上記（３）の構成によれば、シールド端子の円筒部に形成された絶縁部材加締部の加締工程は、シールド端子のシールド部材加締部を加締める際に同時に行うため、専用の加締工程を追加する必要がなくなる。したがって、製造工程が増えることがなく、生産性を向上させることができる。 According to the configuration of (1) above, the pair of slits are formed in the middle portion of the cylindrical portion in the longitudinal direction so as to be separated from each other in the longitudinal direction along the circumferential direction of the cylindrical portion. A cut portion is formed so as to extend along the direction, and an insulating member caulking portion is formed at an intermediate portion of the cylindrical portion by the pair of slits and the cut portion. Thereby, the insulation member crimping part provided in the cylindrical part is bent inside the cylindrical part by a predetermined tool, and bites into a part of the outer peripheral surface of the insulating member. For this reason, the insulating member crimping part is bent inside the cylindrical part, and the insulating member attached to the cylindrical part of the shield terminal is fixed in the cylindrical part. That is, the insulating member itself does not need to be provided with a step portion for preventing the cylindrical portion from coming off, and in addition, a locking piece or the like is formed on the inner peripheral surface of the cylindrical portion of the shield terminal. There is no need to do. This eliminates the need for a stepped portion on the outer peripheral surface of the insulating member, and eliminates the need for protruding locking pieces on the inner peripheral surface of the cylindrical portion of the shield terminal to prevent these parts from falling out. Because it can be a simple structure with little shape change in the direction, impedance disturbance due to shape change in the radial direction of the dielectric or conductor inside the shield terminal can be prevented, and high frequency characteristics can be improved. it can. Further, since the shield terminal and the insulating member can be made simple, these parts can be easily processed and molded, and the manufacturing cost of these parts can be reduced.
According to the configuration of (2) above, the shield terminal is formed by bending a plate material having a predetermined shape inward, and the side surfaces located at both edges of the plate material are opposed to each other. It is formed by arranging. For this reason, there is no need to newly form a cut portion, that is, a shield terminal is formed by press working, and a joint formed at this time (a portion where both side surfaces are arranged to face each other) is used as a cut portion. The insulating member caulking portion can be easily formed simply by forming a pair of slits so as to intersect the seam. Thereby, manufacturing cost can be reduced.
According to the configuration (3) above, the crimping process of the insulating member crimping portion formed on the cylindrical portion of the shield terminal is performed simultaneously with the crimping of the shield member crimping portion of the shield terminal. There is no need to add a tightening process. Therefore, the number of manufacturing steps does not increase and productivity can be improved.

本発明によれば、コネクタ端子の内部でのインピーダンスの乱れを無くして、高周波特性を向上させることができ、加えて、シールド端子及び絶縁部材の構造の簡素化を図って、これらの部品の製造コストを低減することのできるシールド電線付きコネクタ端子、並びにシールド電線付きコネクタ端子の製造方法を提供することができる。 According to the present invention, it is possible to improve the high frequency characteristics by eliminating the disturbance of the impedance inside the connector terminal, and in addition, simplify the structure of the shield terminal and the insulating member, and manufacture these components. The manufacturing method of the connector terminal with a shielded electric wire and the connector terminal with a shielded electric wire which can reduce cost can be provided.

一方、端子本体２０ａは、所謂プラグ型端子（雄型コネクタ）であり、図５に示すように、一端部に中心導体加締部２１ａを有して同軸ケーブル１の一端部で中心導体１１に電気的に接続された、相手方端子に中心導体１１を電気的に接続するための導通性金属製の中心導体導通端子（芯線導通端子：一般的に「中心コンタクト」と呼ばれる）２１と、この中心導体導通端子２１が中心導体１１に電気的に接続した状態でこの中心導体１１と伴に貫通し且つ係止される貫通孔２５ａが形成された絶縁部材（絶縁部材：例えば、ポリエチレン等による発泡誘電体）２５と、この絶縁部材２５に外嵌し且つ中心導体導通端子２１の周囲を包囲しながらこの中心導体導通端子２１を、絶縁部材２５を介して支持する円筒部２３ｃが一端部に設けられ、同軸ケーブル１の一端部で外部導体１５を加締めるための外部導体加締部（シールド部材加締部）２３ａ及び絶縁外皮１７を加締めるための絶縁外皮加締部（外部被覆加締部）２３ｂが他端部で連設され、且つこの外部導体１５に電気的に接続される導電性金属製のシールド端子２３と、を備えている。
なお、同軸ケーブル１の一端部で露出された中心導体１１と中心導体導通端子２１との接続部、即ち中心導体１１の加締め状態にある中心導体加締部２１ａは、その外周を熱収縮性チューブ１１７により密着状態で覆われており、また絶縁部材２５により、シールド端子２３内に挿入された中心導体導通端子２１とシールド端子２３との間に所定の誘電率が確保されることになる。 On the other hand, the terminal main body 20a is a so-called plug-type terminal (male connector), and has a central conductor crimping portion 21a at one end and is connected to the central conductor 11 at one end of the coaxial cable 1 as shown in FIG. An electrically connected central conductor conducting terminal (core wire conducting terminal: generally called “center contact”) 21 for electrically connecting the central conductor 11 to the counterpart terminal, and the center Insulating member (insulating member: foamed dielectric made of, for example, polyethylene or the like) in which a through hole 25a that penetrates and is engaged with the central conductor 11 in a state where the conductor conducting terminal 21 is electrically connected to the central conductor 11 is formed. Body) 25 and a cylindrical portion 23c that is externally fitted to the insulating member 25 and supports the central conductor conducting terminal 21 via the insulating member 25 while surrounding the central conductor conducting terminal 21. An outer conductor caulking portion (shield member caulking portion) 23a for caulking the outer conductor 15 at one end of the coaxial cable 1 and an insulating outer sheath caulking portion (outer sheath caulking portion) 23b for caulking the insulating outer shell 17 Are connected at the other end and are electrically connected to the outer conductor 15 and a shield terminal 23 made of conductive metal.
It should be noted that the connection portion between the central conductor 11 and the central conductor conduction terminal 21 exposed at one end of the coaxial cable 1, that is, the central conductor crimping portion 21a in the crimped state of the central conductor 11, has a heat shrinkable outer periphery. The tube 117 is covered in close contact, and the insulating member 25 ensures a predetermined dielectric constant between the central conductor conduction terminal 21 inserted in the shield terminal 23 and the shield terminal 23.

また、シールド端子２３は、加工後、前述した円筒部２３ｃ、外部導体加締部２３ａ、及び絶縁外皮加締部２３ｂを得るための所定の形状を有した板材を、例えばプレス加工により内側に曲げられることにより成形されており、この結果、この曲げられた板材の両縁部に位置する側面が対峙する（合わさる）ように配置されることで、円筒部２３ｃが形成されることになる（図１及び図５参照）。また、このとき、この側面の合わせにより、円筒部２３ｃには、長手方向にわたって１本の切れ目部２３ｄが形成されることになる。 In addition, after processing, the shield terminal 23 is formed by bending a plate material having a predetermined shape for obtaining the above-described cylindrical portion 23c, outer conductor crimping portion 23a, and insulating outer shell crimping portion 23b, for example, by pressing. As a result, the cylindrical portion 23c is formed by arranging the side surfaces located at both edge portions of the bent plate material so as to confront each other (see FIG. 4). 1 and FIG. 5). Further, at this time, due to the alignment of the side surfaces, one cut portion 23d is formed in the cylindrical portion 23c in the longitudinal direction.

さらに、長手方向の、シールド端子２３の円筒部２３ｃの中間部には、この切れ目２３ｄを跨ぐように１対のスリット３１，３２が、例えばパンチ加工により長手方向で互いに離間するように形成されている。即ち、切れ目部２３ｄは、この一対のスリット３１，３２を長手方向に沿って架け渡しており、この一対のスリット３１，３２，及び切れ目部２３ｄにより絶縁部材加締部３４，３５が円筒部２３ｃの中間部に形成されることになる。そして、後述するように、絶縁部材加締部３４，３５は、絶縁部材２５を円筒部２３ｃ内に固定するように、円筒部２３ｃの内側に曲げられることになる。 Further, a pair of slits 31 and 32 are formed in the middle portion of the cylindrical portion 23c of the shield terminal 23 in the longitudinal direction so as to straddle the cut 23d so as to be separated from each other in the longitudinal direction by punching, for example. Yes. That is, the cut portion 23d spans the pair of slits 31 and 32 along the longitudinal direction, and the insulating member crimping portions 34 and 35 are formed into the cylindrical portion 23c by the pair of slits 31 and 32 and the cut portion 23d. It will be formed in the middle part. As will be described later, the insulating member crimping portions 34 and 35 are bent inside the cylindrical portion 23c so as to fix the insulating member 25 in the cylindrical portion 23c.

シールド端子２３の円筒部２３ｃに装着される絶縁部材２５は、図３に示すように、外周に段部のない単純な厚肉円筒構造に形成されており、図１等に示すように、シールド端子２３に挿入された後、絶縁部材加締部３４，３５の加締めにより、円筒部２３ｃ内に固定されることになる。 As shown in FIG. 3, the insulating member 25 attached to the cylindrical portion 23c of the shield terminal 23 is formed in a simple thick cylindrical structure having no stepped portion on the outer periphery. As shown in FIG. After being inserted into the terminal 23, the insulating member crimping portions 34 and 35 are crimped to be fixed in the cylindrical portion 23c.

次に、前述のように形成された、シールド端子２３の円筒部２３ｃの絶縁部材加締部３４，３５の加締めを行う方法について、図５を参照して、説明する。
まず、前述した、一端部において、中心導体１１、絶縁物１３、及び外部導体１５のそれぞれが露出された同軸ケーブル１を用意する（即ち、シールド電線用意工程）と共に、前述した、中心導体導通端子２１、絶縁部材２５、シールド端子２３を有した端子本体２０ａを用意する（即ち、端子本体用意工程）。 Next, a method for caulking the insulating member caulking portions 34 and 35 of the cylindrical portion 23c of the shield terminal 23 formed as described above will be described with reference to FIG.
First, the coaxial cable 1 in which the central conductor 11, the insulator 13, and the outer conductor 15 are exposed at one end as described above is prepared (that is, a shielded wire preparation step), and the central conductor conduction terminal described above is prepared. 21, a terminal body 20a having an insulating member 25 and a shield terminal 23 is prepared (that is, a terminal body preparing step).

そして、同軸ケーブル１の一端部で露出された中心導体１１に中心導体導通端子２１を導通接続する中心導体導通端子接続工程（即ち、芯線導通端子接続工程）を実施して中心導体導通端子２１が一端に接続された同軸ケーブル１を製造する。なお、このとき、中心導体加締部２１ａの外周を熱収縮性チューブ１１７により密着状態で覆う。
一方、シールド端子２３の円筒部２３ｃ内に絶縁部材２５を挿入する（即ち、絶縁部材挿入工程）。 Then, a center conductor conduction terminal connection step (that is, a core wire conduction terminal connection step) in which the center conductor conduction terminal 21 is conductively connected to the center conductor 11 exposed at one end of the coaxial cable 1 is performed, so that the center conductor conduction terminal 21 is The coaxial cable 1 connected to one end is manufactured. At this time, the outer periphery of the center conductor crimping portion 21a is covered with the heat-shrinkable tube 117 in a close contact state.
On the other hand, the insulating member 25 is inserted into the cylindrical portion 23c of the shield terminal 23 (that is, the insulating member inserting step).

次に、同軸ケーブル１の一端部に接続された中心導体導通端子２１を、絶縁部材２５が装着されたシールド端子２３の内部に挿入して、絶縁部材２５の貫通孔に中心導体導通端子２１を係止すると共に、同軸ケーブル１の一端部で露出された外部導体１５をシールド端子２３の外部導体加締部２３ａに、そして絶縁外皮１７をシールド端子２３の絶縁外皮加締部２３ｂに、それぞれ配置する｛即ち、中心導体導通端子挿入工程（芯線導通端子挿入工程）｝。 Next, the center conductor conduction terminal 21 connected to one end of the coaxial cable 1 is inserted into the shield terminal 23 to which the insulation member 25 is attached, and the center conductor conduction terminal 21 is inserted into the through hole of the insulation member 25. The outer conductor 15 exposed at one end of the coaxial cable 1 is disposed on the outer conductor crimping portion 23a of the shield terminal 23, and the insulating sheath 17 is disposed on the insulating sheath crimping portion 23b of the shield terminal 23. {I.e., center conductor conductive terminal insertion step (core wire conductive terminal insertion step)}.

そして、この結果得られたコネクタ端子２０の組上状態において、３つの加締用プレス型４１，４２，４３を有してこれらが同時に協動するプレス機を用いて、絶縁部材加締部３４，３５、外部導体加締部２３ａ、及び絶縁外皮２３ｂを同時に、シールド端子２３の内側に曲げて加締める。このとき、図５に示すように、加締用プレス型４１，４２が外部導体加締部２３ａ及び絶縁外皮２３ｂをそれぞれシールド端子２３の内側に曲げ、加締用プレス型４３が、絶縁部材加締部３４，３５をシールド端子２３の内側に曲げることになる。 Then, in the assembled state of the connector terminal 20 obtained as a result, the insulating member caulking portion 34 is provided by using a press machine having three caulking press dies 41, 42, and 43 that simultaneously cooperate. , 35, the outer conductor caulking portion 23a, and the insulating outer sheath 23b are simultaneously bent and caulked inside the shield terminal 23. At this time, as shown in FIG. 5, the crimping press dies 41 and 42 bend the outer conductor crimping portion 23a and the insulation sheath 23b to the inside of the shield terminal 23, respectively, and the crimping press die 43 The fastening portions 34 and 35 are bent inside the shield terminal 23.

ここで、シールド端子２３の内側に曲げられた絶縁部材加締部３４，３５は、図２に示すように、それぞれの先端部３４ａ，３５ａが絶縁部材２５の内部に食い込み、これにより絶縁部材２５が円筒部２３ｃ内に確実に固定されることになる。 Here, as shown in FIG. 2, the insulating member crimping portions 34 and 35 bent inside the shield terminal 23 have their tip portions 34 a and 35 a bite into the insulating member 25, whereby the insulating member 25. Is securely fixed in the cylindrical portion 23c.

以上説明したように、本実施形態によれば、コネクタ端子２０では、長手方向の、円筒部２３ｃの中間部に、一対のスリット３１，３２が円筒部２３ｃの周方向に沿って且つ長手方向で互いに離間するように形成され、一対のスリット３１，３２を長手方向に沿って架け渡すように切れ目部２３ｄが形成され、一対のスリット３１，３２及び切れ目部２３ｄにより円筒部２３ｃの中間部に絶縁部材加締部３４，３５が形成される。これにより、円筒部２３ｃに設けられた絶縁部材加締部３４，３５が、所定の工具により円筒部２３ｃの内側に曲げられ、絶縁部材２５の外周面の一部に食い込む。このため、シールド端子２３の円筒部２３ｃに装着される絶縁部材２５は、円筒部２３ｃ内に固定されることになる。 As described above, according to the present embodiment, in the connector terminal 20, the pair of slits 31 and 32 are provided along the circumferential direction of the cylindrical portion 23c and in the longitudinal direction at the intermediate portion of the cylindrical portion 23c in the longitudinal direction. The slit 23d is formed so as to be spaced apart from each other and spans the pair of slits 31 and 32 along the longitudinal direction, and is insulated by the pair of slits 31 and 32 and the slit 23d at an intermediate portion of the cylindrical portion 23c. Member caulking portions 34 and 35 are formed. Thereby, the insulating member crimping parts 34 and 35 provided in the cylindrical part 23c are bent inside the cylindrical part 23c by a predetermined tool and bite into a part of the outer peripheral surface of the insulating member 25. For this reason, the insulating member 25 attached to the cylindrical portion 23c of the shield terminal 23 is fixed in the cylindrical portion 23c.

即ち、絶縁部材２５自体には、円筒部２３ｃからの抜け止めを防止するための段部を形成する必要なく、加えて、シールド端子２３の円筒部２３ｃにおいても、その内周面に係止片等を突出形成する必要がない。このため、絶縁部材２５の外周面に段部が不要になり、また、シールド端子２３の円筒部２３ｃの内周面に抜け止めを防止するため係止片を突設する必要もなくなり、これらの部品を径方向における形状変化の少ない簡素な構造にすることができるため、シールド端子２３の内部での誘電体や導体の径方向における形状変化に起因するインピーダンスの乱れを防止でき、高周波特性の向上を図ることができる。また、シールド端子２３及び絶縁部材２５を簡素な構造にできるため、これらの部品の加工や成形が容易になり、これらの部品の製造コストを低減させることもできる。 That is, the insulating member 25 itself does not need to be formed with a step portion for preventing the cylindrical member 23c from coming off, and in addition, the cylindrical member 23c of the shield terminal 23 also has a locking piece on its inner peripheral surface. There is no need to form a protrusion or the like. This eliminates the need for a stepped portion on the outer peripheral surface of the insulating member 25 and eliminates the need for protruding locking pieces to prevent the cylindrical member 23c of the shield terminal 23 from coming off. Since the parts can be made to have a simple structure with little shape change in the radial direction, impedance disturbance due to the shape change in the radial direction of the dielectric or conductor inside the shield terminal 23 can be prevented, and high frequency characteristics can be improved. Can be achieved. Moreover, since the shield terminal 23 and the insulating member 25 can be made into a simple structure, these parts can be easily processed and molded, and the manufacturing cost of these parts can be reduced.

また、本実施形態によれば、シールド端子２３は、所定の形状を有した板材を内側に曲げることにより形成されており、切れ目部２３ｄは、この板材の両縁部に位置する側面が対峙する（合わさる）ように配置されることで形成される。このため、切れ目部２３ｄを新たに形成する必要がなくなり、即ち、プレス加工によりシールド端子２３を成形して、このとき形成される合わせ目（両側面が対峙配置される部分）を切れ目部として利用して、この合わせ目に交差するように一対のスリット３１，３２を形成するだけで、容易に絶縁部材加締部３４，３５を形成することができる。これにより、製造コストを低減することができる。 In addition, according to the present embodiment, the shield terminal 23 is formed by bending a plate material having a predetermined shape inward, and the cut portions 23d are opposed to the side surfaces located at both edges of the plate material. It is formed by being arranged so as to be combined. For this reason, it is not necessary to newly form the cut portion 23d, that is, the shield terminal 23 is formed by press working, and the joint formed at this time (the portion where both side surfaces are opposed to each other) is used as the cut portion. Then, the insulating member crimping portions 34 and 35 can be easily formed simply by forming the pair of slits 31 and 32 so as to intersect the seam. Thereby, manufacturing cost can be reduced.

さらに、本実施形態に係るコネクタ端子２０の製造方法によれば、シールド端子２３の円筒部２３ｃに形成された絶縁部材加締部３４，３５の加締工程は、シールド端子２３の外部導体加締部２３ａ及び絶縁外皮加締分２３ｂを加締める際に同時に行うため、専用の加締工程を追加する必要がなくなる。したがって、製造工程が増えることがなく、生産性を向上させることができる。 Furthermore, according to the manufacturing method of the connector terminal 20 according to the present embodiment, the step of crimping the insulating member crimping portions 34 and 35 formed on the cylindrical portion 23 c of the shield terminal 23 is performed by the outer conductor crimping of the shield terminal 23. Since it is performed simultaneously with the caulking of the portion 23a and the insulating sheath caulking portion 23b, it is not necessary to add a dedicated caulking process. Therefore, the number of manufacturing steps does not increase and productivity can be improved.

なお、本発明に係るコネクタ端子によりコネクタ接続される電線は、前述した実施形態に示した同軸ケーブルに限るものではなく、例えば、中心導体の他にシールド用の外部導体を備える各種の同軸ケーブル１にも応用可能である。例えば、前述した実施形態では、その絶縁物と絶縁外皮とに介在する外部導体として編組を備えたものを説明したが、これに限らず、外部導体は、編組の外周にアルミニウム箔、銅箔、等といった金属箔を更に巻きつけたもの、或いは絶縁物の外周に巻きつけられたアルミニウム箔、銅箔、等といった金属箔を更に有するものであってもよい。また、同軸ケーブルは、編組の代わりにスパイラル状のシールド線を備えたものであってもよい。 In addition, the electric wire connected by the connector terminal according to the present invention is not limited to the coaxial cable shown in the above-described embodiment. For example, various coaxial cables 1 including a central conductor and an outer conductor for shielding. It can also be applied to. For example, in the above-described embodiment, the outer conductor provided between the insulator and the insulating outer shell has been described as having the braid, but the outer conductor is not limited thereto, and the outer conductor is formed of an aluminum foil, a copper foil, Further, a metal foil such as an aluminum foil or a copper foil wound around the outer periphery of the insulator may be further provided.
