Description

本発明は、電線に接続される接続端子に関する。   The present invention relates to a connection terminal connected to an electric wire.
この種の接続端子は、従来より種々提案されている。図3には、従来の接続端子を使用したシールドコネクタが示されている(特許文献1,2参照)。   Various types of connection terminals of this type have been proposed. FIG. 3 shows a shield connector using a conventional connection terminal (see Patent Documents 1 and 2).
図5において、シールドコネクタ50は、インナーハウジング51と、このインナーハウジング51内に収容された複数の接続端子52と、インナーハウジング51の外周を被うシールドシェル60とを備えている。   In FIG. 5, the shield connector 50 includes an inner housing 51, a plurality of connection terminals 52 accommodated in the inner housing 51, and a shield shell 60 that covers the outer periphery of the inner housing 51.
インナーハウジング51は、所定の誘電率の絶縁体より形成されている。各接続端子52は、電線接続部53と、相手端子との接続を行う接点部54とを有する。電線接続部53には、シールド電線W1の各芯線70がそれぞれ接続されている。シールドシェル60は、導電性材より形成されている。シールドシェル60は、シールド本体61とこれに組み付けされるシールドカバー62とから構成されている。シールド本体61とシールドカバー62の後端部には、シールド電線W1のシールド線71が加締めによって接続されている。   The inner housing 51 is formed of an insulator having a predetermined dielectric constant. Each connection terminal 52 has an electric wire connection portion 53 and a contact portion 54 for connecting to a counterpart terminal. Each core wire 70 of the shielded electric wire W1 is connected to the electric wire connecting portion 53. The shield shell 60 is made of a conductive material. The shield shell 60 includes a shield body 61 and a shield cover 62 assembled to the shield body 61.

しかしながら、前記従来の接続端子52は、図6に詳しく示すように、電線接続部53と接点部54が一直線状に直列に配置されている。従って、接続端子52の長さ寸法L2が長いという問題がある。特に、上記したシールドコネクタ50は、シールド電線W1の芯線70とシールド線71をそれぞれ接続する必要があるため、他種類のコネクタと較べて長寸法となる。そのため、シールドコネクタ50では、接続端子52の長さ寸法L2を極力短くすることが特に要請される。   However, in the conventional connection terminal 52, as shown in detail in FIG. 6, the wire connection portion 53 and the contact portion 54 are arranged in series in a straight line. Therefore, there is a problem that the length L2 of the connection terminal 52 is long. In particular, since the shield connector 50 described above needs to connect the core wire 70 and the shield wire 71 of the shielded electric wire W1, each of the shield connectors 50 has a longer dimension than other types of connectors. Therefore, the shield connector 50 is particularly required to shorten the length dimension L2 of the connection terminal 52 as much as possible.
そこで、本発明は、前記した課題を解決すべくなされたものであり、長さ寸法の短い接続端子を提供することを目的とする。   Accordingly, the present invention has been made to solve the above-described problems, and an object thereof is to provide a connection terminal having a short length.
本発明は、導電性材より形成され、電線を接続する電線接続部と、相手端子との接続を行う接点部とを備え、前記電線接続部と前記接点部が並列に配置され、前記電線接続部と前記接点部のいずれか長い方の範囲内で短い方が並列に配置され、前記電線接続部は、前記接点部の反対面側が電線配置面とされていることを特徴とする。 The present invention comprises an electric wire connecting portion that is formed of a conductive material and connects an electric wire and a contact portion that connects to a mating terminal, and the electric wire connecting portion and the contact portion are arranged in parallel, and the electric wire connection The shorter one is arranged in parallel within the longer range of the contact portion and the contact portion, and the electric wire connecting portion has an electric wire arrangement surface on the opposite surface side of the contact portion .
前記電線接続部には、前記電線内に突き刺す爪部が設けられることが好ましい。   It is preferable that the electric wire connection portion is provided with a claw portion that pierces into the electric wire.
前記電線接続部と前記接点部は、双方の前端で連結部を介して連結されることが好ましい。   It is preferable that the electric wire connection portion and the contact point portion are connected via a connecting portion at both front ends.
本発明によれば、電線接続部と接点部のいずれか長い方の寸法が接続端子の長さ寸法となるため、接続端子の長さ寸法が短くなる。   According to the present invention, since the longer dimension of the wire connection portion and the contact portion is the length dimension of the connection terminal, the length dimension of the connection terminal is shortened.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(第1実施形態)
図1及び図2は、本発明の第1実施形態を示す。図1及び図2に示すように、接続端子1Aは、1枚の導電性金属材である銅合金材の板を折り曲げることによって形成されている。接続端子1Aは、電線Wを接続する電線接続部2と、相手端子(図示せず)との接続を行う接点部10と、電線接続部2と接点部10間を連結する連結部20とを備えている。
(First embodiment)
1 and 2 show a first embodiment of the present invention. As shown in FIGS. 1 and 2, the connection terminal 1 </ b> A is formed by bending a sheet of copper alloy material, which is a single conductive metal material. The connection terminal 1 </ b> A includes an electric wire connection portion 2 for connecting the electric wire W, a contact portion 10 for connecting to a mating terminal (not shown), and a connecting portion 20 for connecting the electric wire connection portion 2 and the contact portion 10. I have.
電線接続部2は、接点部10とは反対側である上面が電線配置面3として形成されている。電線配置面3には、他の箇所よりも一段高いハンダ接続面3aが形成されている。   The electric wire connection portion 2 has an upper surface on the side opposite to the contact portion 10 formed as an electric wire arrangement surface 3. On the electric wire arrangement surface 3, a solder connection surface 3a that is one step higher than other portions is formed.
接点部10は、上面接触片部11と、この上面接触片部11の後端側より前方に向かって大きく折り曲げられた弾性接触片部12とを有する。接点部10は、雌接点形状である。相手端子であるオス端子(図示せず)が上面接触片部11と弾性接触片部12の間に挿入されると、弾性接触片部12の撓み復帰力によって密着され、電気的に接続される。   The contact portion 10 includes an upper surface contact piece portion 11 and an elastic contact piece portion 12 that is largely bent forward from the rear end side of the upper surface contact piece portion 11. The contact portion 10 has a female contact shape. When a male terminal (not shown), which is a mating terminal, is inserted between the upper surface contact piece 11 and the elastic contact piece 12, it is brought into close contact with and electrically connected by the bending return force of the elastic contact piece 12. .
連結部20は、電線接続部2と接点部10の双方の前端同士を連結している。連結部20で連結された電線接続部2と接点部10は、並列に、つまり、側面から見て上下縦並びに配置されている。   The connecting portion 20 connects the front ends of both the wire connecting portion 2 and the contact portion 10. The wire connecting part 2 and the contact part 10 connected by the connecting part 20 are arranged in parallel, that is, vertically and vertically as viewed from the side.
電線Wは、導体30とこの外周を被う絶縁外皮31とから構成されている。電線Wの先端側は、最先端の絶縁外皮31を残してその少し内側の絶縁外皮31が剥ぎ取られている。これにより、電線Wは、先端より少し内側の一部区間で導体30が外部に露出されている。   The electric wire W is composed of a conductor 30 and an insulating sheath 31 covering the outer periphery. At the tip end side of the electric wire W, the insulating sheath 31 is peeled off slightly inside, leaving the most advanced insulating sheath 31. Thereby, as for the electric wire W, the conductor 30 is exposed outside in the partial area a little inside from the front-end | tip.
電線Wの先端側は、導体30の露出箇所がハンダ接続面3aに載置される位置で電線接続部2の電線配置面3に配置されている。そして、導体30とハンダ接続面3a間がハンダ付けされている。   The tip end side of the electric wire W is arranged on the electric wire arrangement surface 3 of the electric wire connection portion 2 at a position where the exposed portion of the conductor 30 is placed on the solder connection surface 3a. The conductor 30 and the solder connection surface 3a are soldered.
上記構成において、接続端子1Aは、電線接続部2と接点部10が並列に、つまり、側面から見て上下縦並びに配置されている。従って、電線接続部2と接点部10のいずれか長い方の寸法、この実施形態では電線接続部2の寸法が接続端子1Aの長さ寸法L1となるため、接続端子1Aの長さ寸法L1が短くなる。   In the above configuration, in the connection terminal 1A, the wire connection portion 2 and the contact portion 10 are arranged in parallel, that is, vertically and vertically as viewed from the side. Accordingly, since the longer dimension of the wire connecting portion 2 and the contact portion 10, in this embodiment, the dimension of the wire connecting portion 2 is the length dimension L1 of the connecting terminal 1A, the length dimension L1 of the connecting terminal 1A is Shorter.
電線接続部2は、接点部10の反対面側が電線配置面3とされている。従って、電線配置面3の上方が開放スペースとなるため、電線Wの配置作業及び固定作業が容易である。   The electric wire connection portion 2 has an electric wire arrangement surface 3 on the opposite surface side of the contact portion 10. Therefore, since the upper part of the electric wire arrangement surface 3 becomes an open space, the arrangement work and fixing work of the electric wire W are easy.
電線接続部2と接点部10は、双方の前端で連結部20を介して連結されている。従って、接点部10を雌端子形状として容易に作成できる。   The electric wire connection part 2 and the contact part 10 are connected via a connecting part 20 at both front ends. Therefore, the contact part 10 can be easily formed as a female terminal shape.
電線接続部2の電線配置面3には、他の面より一段高いハンダ接続面3aが形成されている。従って、電線Wとのハンダ付けを確実に、しかも、強固なハンダ付けとすることができる。   The wire connection surface 3 of the wire connection portion 2 is formed with a solder connection surface 3a that is one step higher than the other surfaces. Therefore, the soldering with the electric wire W can be performed reliably and firmly.
(第2実施形態)
図3及び図4は、本発明の第2実施形態を示す。図3及び図4に示すように、接続端子1Bは、前記第1実施形態の接続端子1Aと比較するに、電線接続部2に爪部4が設けられている点のみが相違する。爪部4は、電線接続部2の一部の切り起こしによって形成されている。爪部4の端面は、刃状に形成されている。爪部4は、電線W内に突き刺さっている。
(Second Embodiment)
3 and 4 show a second embodiment of the present invention. As shown in FIGS. 3 and 4, the connection terminal 1 </ b> B is different from the connection terminal 1 </ b> A of the first embodiment only in that a claw portion 4 is provided on the wire connection portion 2. The claw portion 4 is formed by cutting and raising a part of the electric wire connection portion 2. The end surface of the nail | claw part 4 is formed in blade shape. The claw portion 4 is pierced into the electric wire W.
他の構成は、前記第1実施形態と同様であるため、図面の同一構成箇所には同一符号を付して説明を省略する。   Since other configurations are the same as those of the first embodiment, the same components in the drawings are denoted by the same reference numerals, and description thereof is omitted.
この第2実施形態では、前記第1実施形態と同様の理由によって、接続端子1Bの長さ寸法L1が短くなる等の効果がある。   In the second embodiment, for the same reason as in the first embodiment, there is an effect that the length L1 of the connection terminal 1B is shortened.
電線接続部2には、爪部4が設けられている。従って、接続端子1Bは、電線Wに作用する引っ張り力Pをハンダ固定力と爪部4の係止力によって受けるため、電線Wの引っ張り強度が向上する。爪部4が導体30に接触することにより、電線接続抵抗が低くなる。   The wire connection portion 2 is provided with a claw portion 4. Therefore, since the connection terminal 1B receives the tensile force P acting on the electric wire W by the solder fixing force and the locking force of the claw portion 4, the tensile strength of the electric wire W is improved. When the nail | claw part 4 contacts the conductor 30, electric wire connection resistance becomes low.
(変形例)
前記各実施形態では、接続端子1A,1Bには電線Wの導体30がハンダ付けで接続されているが、接続手段は問わない。
(Modification)
In each said embodiment, although the conductor 30 of the electric wire W is connected to the connecting terminals 1A and 1B by soldering, a connection means is not ask | required.
上記した接続端子1A,1Bをシールドコネクタに適用すれば、シールドコネクタの短寸法化の要請に応えることができ、好ましい。   If the connection terminals 1A and 1B described above are applied to a shielded connector, it is possible to meet the demand for shortening the size of the shielded connector, which is preferable.
