Description

本発明は、コネクタ同士を接続するジョイントコネクタに装備される端子構造に関する。   The present invention relates to a terminal structure equipped in a joint connector for connecting connectors to each other.

従来の端子構造として、コネクタハウジング内に、端子部をそれぞれ有する２個のバスバーを組み付けたものが知られている（例えば、特許文献１参照）。   As a conventional terminal structure, one in which two bus bars each having a terminal portion are assembled in a connector housing is known (for example, see Patent Document 1).

図５に示すように、特許文献１に開示された端子構造は、２個のバスバー１０１の両端部に複数の端子部１０２をそれぞれ有する。バスバー１０１は、一方側の端子部１０２が開口部品１０３の取り付け孔１０４に組み付けられ、バスバー１０１が組み付けられた開口部品１０３がハウジング本体１０５に嵌合されることで、バスバー１０１の他方側の端子部１０２がハウジング本体１０５の取り付け孔１０６に組み付けられる。   As shown in FIG. 5, the terminal structure disclosed in Patent Document 1 includes a plurality of terminal portions 102 at both ends of two bus bars 101.

特開２００３−７７６００号公報（図１）Japanese Patent Laying-Open No. 2003-77600 (FIG. 1)

ところが、上記特許文献１に開示された従来の端子構造においては、端子部１０２を有するバスバー１０１、即ちプレス加工によって複数の端子部１０２を同一平面上に設けた板状導電部材を用いているために、それぞれのバスバー１０１の板方向（横方向）への導通経路は形成できるが、上下に配置されたそれぞれのバスバー１０１同士（縦方向）、或いは、複数の端子部１０２のうちのバスバー１０１毎に選択されたそれぞれの端子部１０２の導通経路を形成することができない。   However, the conventional terminal structure disclosed in Patent Document 1 uses a bus bar 101 having terminal portions 102, that is, a plate-like conductive member provided with a plurality of terminal portions 102 on the same plane by pressing. In addition, a conduction path in the plate direction (lateral direction) of each bus bar 101 can be formed, but each bus bar 101 arranged vertically (in the vertical direction) or for each bus bar 101 among the plurality of terminal portions 102. Thus, it is not possible to form a conduction path for each of the selected terminal portions 102.

また、複数の端子部１０２を同一平面上に設けた板状導電部材のバスバー１０１であるために、回路変更が生じた際に、端子部１０２を新たに設けたバスバー１０１を作成するか、或いは２個のバスバー１０１に加えて新たなバスバー１０１を付加することとなり、その結果、加工工数の増大をまねくばかりか、生産性の向上を図り難い。   In addition, since the bus bar 101 is a plate-like conductive member provided with a plurality of terminal portions 102 on the same plane, when a circuit change occurs, the bus bar 101 newly provided with the terminal portions 102 is created, or In addition to the two bus bars 101, a new bus bar 101 is added. As a result, the number of processing steps is increased and it is difficult to improve productivity.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、回路形成の自由度を拡張することができるとともに生産性の向上を図ることができる端子構造を提供することにある。   The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a terminal structure capable of expanding the degree of freedom of circuit formation and improving productivity.

１）本発明に係る端子構造は、相手コネクタとの嵌合方向に沿って２分割形成されたコネクタハウジング内に装着される回路基板に形成された端子挿通孔に挿着され、前記回路基板に電気的に接続される本体部と、該本体部の挿着方向に沿った前後両端に突設された外部接続部とを有する端子構造であって、前記本体部後方側に、後方側のコネクタハウジングに当接する当接部と、前記本体部前方側に、前記端子挿通孔に圧接挿着されるプレスフィット部と、該プレスフィット部前端側の前記外部接続部に前方側のコネクタハウジングに圧入固定される突起と、を備えていることを特徴とする。
1) A terminal structure according to the present invention is inserted into a terminal insertion hole formed in a circuit board to be mounted in a connector housing formed in two parts along a fitting direction with a mating connector, A terminal structure having an electrically connected main body portion and external connection portions projecting at both front and rear ends along the insertion direction of the main body portion, the rear connector on the rear side of the main body portion A contact portion that contacts the housing; a press-fit portion that is press-fitted into the terminal insertion hole on the front side of the main body portion; and a press-fit connector housing on the front side into the external connection portion on the front end side of the press-fit portion And a protrusion to be fixed.

上記１）に記載の発明によれば、本体部後方側に、後方側のコネクタハウジングに当接する当接部と、本体部前方側に、端子挿通孔に圧接挿着されるプレスフィット部と、該プレスフィット部前端側の外部接続部に前方側のコネクタハウジングに圧入固定される突起と、を備えているので、プレスフィット部が回路基板の端子挿通孔に圧接挿着されて確実に保持されるとともに、当接部が後方側のコネクタハウジングに当接することにより端子の挿入量が規制され、突起が前方側のコネクタハウジング内に圧入固定されることにより相手コネクタの嵌合時に端子の後方側への抜け出しを防止することができる。
また、回路基板上の端子挿通孔の横列及び縦列に任意の導通経路が形成されていれば、回路基板上の導通経路に応じて回路を形成することができ、回路変更が生じたとしても、変更された回路を有する回路基板に応じて変更を容易に行うことができる。従って、回路形成の自由度を拡張することができるとともに生産性の向上を図ることができる。 According to the invention described in 1) above, on the rear side of the main body part, an abutting part that comes into contact with the connector housing on the rear side, and on the front side of the main body part, a press fit part that is press-fitted into the terminal insertion hole, The press-fit portion includes an external connection portion on the front end side of the press-fit portion and a protrusion that is press-fitted and fixed to the connector housing on the front side, so that the press-fit portion is press-fitted and securely held in the terminal insertion hole of the circuit board. In addition, the amount of insertion of the terminal is restricted when the abutting part abuts on the rear connector housing, and the protrusion is press-fitted and fixed in the front connector housing, so that the rear side of the terminal is fitted when the mating connector is fitted. It is possible to prevent slipping out.
In addition, if an arbitrary conduction path is formed in the row and column of the terminal insertion holes on the circuit board, a circuit can be formed according to the conduction path on the circuit board, and even if a circuit change occurs, The change can be easily performed according to the circuit board having the changed circuit. Therefore, the degree of freedom in circuit formation can be expanded and productivity can be improved.

２）本発明に係る端子構造は、上記１）に記載の端子構造において、前記突起が２対設けられていることを特徴とする。   2) The terminal structure according to the present invention is characterized in that in the terminal structure described in 1) above, two pairs of the protrusions are provided.

上記２）に記載の発明によれば、突起が２対設けられていることで、相手コネクタの嵌合時に端子の後方側への抜け出しを確実に防止することができる。   According to the invention described in 2) above, since two pairs of protrusions are provided, it is possible to reliably prevent the terminal from being pulled out backward when the mating connector is fitted.

３）本発明に係る端子構造は、上記１）又は２）に記載の端子構造において、前記外部接続部の対向した両側面に設けられた一対の前記突起間の先端幅が、前記端子挿通孔の内径よりも小さく、且つ前記前方側のコネクタハウジングの端子孔の内径よりも大きいことを特徴とする。   3) The terminal structure according to the present invention is the terminal structure according to 1) or 2) described above, wherein a tip width between a pair of the protrusions provided on opposite side surfaces of the external connection portion is the terminal insertion hole. Is smaller than the inner diameter of the terminal housing and larger than the inner diameter of the terminal hole of the connector housing on the front side.

上記３）に記載の発明によれば、一対の突起間の先端幅が端子挿通孔の内径よりも小さいので、プレスフィット部前端側の外部接続部は回路基板の端子挿通孔を容易に挿通してから、前方側のコネクタハウジングの端子孔内に確実に圧入固定される。   According to the invention described in 3) above, since the tip width between the pair of protrusions is smaller than the inner diameter of the terminal insertion hole, the external connection portion on the front end side of the press fit portion can be easily inserted through the terminal insertion hole of the circuit board. Then, it is securely press-fitted into the terminal hole of the connector housing on the front side.

本発明の端子構造によれば、縦方向や任意の方向へ導通回路を形成できない、回路変更の際に伴い加工工数の増大をまねく、生産性の向上を図り難い、という問題を解決でき、これにより、回路形成の自由度を拡張することができるとともに生産性並びに作業性の向上を図ることができるという効果が得られる。   According to the terminal structure of the present invention, it is possible to solve the problems that a conduction circuit cannot be formed in a vertical direction or an arbitrary direction, an increase in processing man-hours accompanying a circuit change, and a difficulty in improving productivity. As a result, the degree of freedom of circuit formation can be expanded and the productivity and workability can be improved.

以下、本発明に係る好適な実施の形態例を図面に基づいて詳細に説明する。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.

図１は本発明の端子構造の一実施形態を用いた端子の外観斜視図、図２は図１に示す端子構造に用いる回路基板の平面図、図３は図１に示す端子構造を用いたジョイントコネクタの分解斜視図、図４は図３に示す端子構造の縦断面図である。   1 is an external perspective view of a terminal using an embodiment of the terminal structure of the present invention, FIG. 2 is a plan view of a circuit board used in the terminal structure shown in FIG. 1, and FIG. 3 is a terminal structure shown in FIG. 4 is an exploded perspective view of the joint connector, and FIG. 4 is a longitudinal sectional view of the terminal structure shown in FIG.

図１に示すように、本発明の一実施形態を用いた端子１０は、本体部１１と、第１外部接続部１２と、第２外部接続部１３と、を備えており、一般的な端子材料である黄銅や鉄等の熱劣化し難い導電金属製板部材をプレス加工することで作成される。   As shown in FIG. 1, a terminal 10 using one embodiment of the present invention includes a main body part 11, a first external connection part 12, and a second external connection part 13. It is created by pressing a conductive metal plate member that is not easily thermally deteriorated, such as brass or iron.

本体部１１は、両外部接続部１２，１３よりも大きい外形に形成されており、第１外部接続部１２側にプレスフィット部１４が形成され、第２外部接続部１３側にコネクタハウジング３０（図３参照）に当接する一対の当接部１５が形成されている。   The main body 11 is formed to have a larger outer shape than both the external connection parts 12, 13, a press-fit part 14 is formed on the first external connection part 12 side, and a connector housing 30 ( A pair of abutting portions 15 that abut on (see FIG. 3) are formed.

プレスフィット部１４は、楕円形の環形状に形成されていて縮径方向に弾性変形可能であり、回路基板１６に有する端子挿通孔１７に圧入されることで、その端子挿通孔１７に圧接挿着される。このとき、回路基板１６上に形成されているプリント配線板（図２参照）１８の回路部が端子挿通孔１７内まで延設されており、このプリント配線板１８とプレスフィット部１４が電気的に接続される。   The press-fit portion 14 is formed in an elliptical ring shape and can be elastically deformed in the direction of diameter reduction, and is press-fitted into the terminal insertion hole 17 by being press-fitted into the terminal insertion hole 17 provided in the circuit board 16. Worn. At this time, the circuit portion of the printed wiring board (see FIG. 2) 18 formed on the circuit board 16 extends into the terminal insertion hole 17, and the printed wiring board 18 and the press-fit portion 14 are electrically connected. Connected to.

当接部１５は、本体部１１の第２外部接続部１３側に配置されており、この端子１０が、回路基板１６の端子挿通孔１７に挿通された際に、コネクタハウジング３０に当接することで、それ以上の挿入が阻止される。   The contact portion 15 is disposed on the second external connection portion 13 side of the main body portion 11, and contacts the connector housing 30 when the terminal 10 is inserted into the terminal insertion hole 17 of the circuit board 16. This prevents further insertion.

第１外部接続部１２は、本体部１１の挿通方向前方側に配置され、第２外部接続部１３は、本体部１１の挿通方向後方側に配置されている。そして、この第１外部接続部１２のプレスフィット部１４側に２対の突起１２ａが突設されている。この突起１２ａは、挿通方向にテーパ面を有する楔形状であり、第１外部接続部１２の対向した両側面に設けられている。この対向した一対の突起１２ａ，１２ａ間の先端幅（最大幅）は、端子挿通孔１７の内径よりも小さく、前方側のコネクタハウジング３２（図３参照）の端子孔３１（図４参照）の内径よりも大きく設定されている。したがって、第１外部接続部１２は、端子挿通孔１７を挿通して端子孔３１内に突起１２ａによって後抜け不可に圧入固定される。   The first external connection portion 12 is disposed on the front side in the insertion direction of the main body portion 11, and the second external connection portion 13 is disposed on the rear side in the insertion direction of the main body portion 11. Then, two pairs of protrusions 12a project from the first external connection part 12 on the press fit part 14 side. The protrusion 12 a has a wedge shape having a tapered surface in the insertion direction, and is provided on both opposing side surfaces of the first external connection portion 12. The tip width (maximum width) between the pair of opposed protrusions 12a, 12a is smaller than the inner diameter of the terminal insertion hole 17, and the terminal hole 31 (see FIG. 4) of the connector housing 32 (see FIG. 3) on the front side. It is set larger than the inner diameter. Accordingly, the first external connection portion 12 is inserted and fixed through the terminal insertion hole 17 so that it cannot be pulled out into the terminal hole 31 by the protrusion 12a.

図２に示すように、回路基板１６は、板形状の基板本体１９に横列６個、縦列４個の２４個の端子挿通孔１７を有する。そして、端子挿通孔１７のそれぞれを繋いでプリント配線板１８が形成されている。プリント配線板１８は、例えば、図２中の最上段の横列における右端の端子挿通孔１７での導通ランド２０と、上から３段目の横列における右から２番目の端子挿通孔１７での導通ランド２０と、最下段の横列における右から３番目及び４番目の端子挿通孔１７での導通ランド２０と、を導通させるように任意の導通パターンが設定されている。   As shown in FIG. 2, the circuit board 16 has 24 terminal insertion holes 17 in six rows and four columns in a plate-shaped board body 19. A printed wiring board 18 is formed by connecting the terminal insertion holes 17. For example, the printed wiring board 18 is connected to the conduction land 20 in the rightmost terminal insertion hole 17 in the uppermost row in FIG. 2 and in the second terminal insertion hole 17 from the right in the third row from the top. An arbitrary conduction pattern is set so that the land 20 and the conduction land 20 in the third and fourth terminal insertion holes 17 from the right in the lowermost row are electrically connected.

図３に示すように、端子１０は、２４個用いられ、第１外部接続部１２を先にして一方のコネクタハウジング３０に形成されている端子孔３１（図４参照）に挿通されるとともに、回路基板１６の端子挿通孔１７に圧接挿入され、他方コネクタハウジング３２に形成されている端子孔３３に挿通される。そして、一方のコネクタハウジング３０が他方のコネクタハウジング３２に嵌め付けられることで、ジョイントコネクタ４０が構成される。   As shown in FIG. 3, 24 terminals 10 are used and inserted into a terminal hole 31 (see FIG. 4) formed in one connector housing 30 with the first external connection portion 12 first. The circuit board 16 is pressed into the terminal insertion hole 17 and is inserted into the terminal hole 33 formed in the other connector housing 32. The joint connector 40 is configured by fitting one connector housing 30 into the other connector housing 32.

このように、端子１０は、単体であって、バスバーのように連結されずに作成される。そして、一方のコネクタハウジング３０と、回路基板１６と、他方のコネクタハウジング３２と、に対して、同一の方向から進行することで、一方のコネクタハウジング３０と、回路基板１６と、他方コネクタハウジング３２に組み付けられる。   Thus, the terminal 10 is a single unit and is created without being connected like a bus bar. The one connector housing 30, the circuit board 16, and the other connector housing 32 are advanced from the same direction with respect to the one connector housing 30, the circuit board 16, and the other connector housing 32. Assembled into.

図４に示すように、圧入前の端子１０は、プレスフィット部１４の外径が回路基板１６の端子挿通孔１７の内径よりもわずかに大きくなっており、回路基板１６の端子挿通孔１７に圧入される。そして、プレスフィット部１４が縮径方向に弾性変形して、端子挿通孔１７に圧接挿着される。このとき、端子挿通孔１７内まで延設されたプリント配線板１８の回路部とプレスフィット部１４が電気的に接続される。
そして、当接部１５が一方のコネクタハウジング３０に当接してそれ以上の挿入が阻止されるとともに、２対の突起１２ａが他方コネクタハウジング３２の端子孔３３内に後抜け不可に圧入固定される。これにより、端子１０は、端子挿通孔１７に確実に保持されるので、両外部接続部１２，１３のアライメントを確保することができる。 As shown in FIG. 4, in the terminal 10 before press-fitting, the outer diameter of the press-fit portion 14 is slightly larger than the inner diameter of the terminal insertion hole 17 of the circuit board 16. Press fit. Then, the press-fit portion 14 is elastically deformed in the diameter reducing direction, and is press-fitted into the terminal insertion hole 17. At this time, the circuit portion of the printed wiring board 18 extended into the terminal insertion hole 17 and the press fit portion 14 are electrically connected.
The abutment portion 15 abuts against one connector housing 30 to prevent further insertion, and the two pairs of protrusions 12a are press-fitted and fixed in the terminal hole 33 of the other connector housing 32 so that they cannot be removed backward. . Thereby, since the terminal 10 is reliably hold | maintained at the terminal insertion hole 17, the alignment of both the external connection parts 12 and 13 is securable.

一方のコネクタハウジング３０には、不図示の一方の相手側コネクタが挿着され、他方のコネクタハウジング３２には、同じく不図示の相手側コネクタが挿着される。このとき、他方コネクタハウジング３２の端子孔３３内に突起１２ａが圧入固定されているので、相手側コネクタ挿着時に端子１０が後抜けするようなことはない。これにより、一方の相手側コネクタに内装された不図示の一方の相手側端子が第２外部接続部１３に電気的に接続されるとともに、他方の相手側コネクタに内装された不図示の他方の相手側端子が第１外部接続部１２に電気的に接続され、一方の相手側端子に接続されている一方の回路が、端子１０と、回路基板１６のプリント配線板１８と、他の端子１０とを通じて他方の相手側端子に接続されている他方の回路に接続される。   One connector housing (not shown) is inserted into one connector housing 30, and the other connector (not shown) is also inserted into the other connector housing 32. At this time, since the protrusion 12a is press-fitted and fixed in the terminal hole 33 of the other connector housing 32, the terminal 10 does not come back backward when the mating connector is inserted. As a result, one counterpart terminal (not shown) housed in one counterpart connector is electrically connected to the second external connector 13 and the other counterpart (not shown) housed in the other counterpart connector. The counterpart terminal is electrically connected to the first external connection portion 12, and one circuit connected to the other counterpart terminal includes the terminal 10, the printed wiring board 18 of the circuit board 16, and the other terminal 10. And connected to the other circuit connected to the other counterpart terminal.

以上説明したように、本発明の一実施形態である端子構造によれば、本体部１１が回路基板１６の端子挿通孔１７に挿入されることで、プレスフィット部１４が端子挿通孔１７に圧接挿着されて確実に保持される。そして、本体部１１が回路基板１６上のプリント配線板１８に電気的に接続される。プリント配線板１８は、回路基板１６上において、端子挿通孔１７の横列及び縦列に任意に導通経路を形成しているために、プリント配線板１８の導通経路に応じて回路を形成することができる。また、回路変更が生じたとしても、変更された回路を有するプリント配線板１８に応じて変更を容易に行うことができる。従って、横方向及び縦方向のみならず回路形成の自由度を拡張することができるとともに生産性の向上を図ることができる。   As described above, according to the terminal structure according to an embodiment of the present invention, the press-fit portion 14 is pressed against the terminal insertion hole 17 by inserting the main body portion 11 into the terminal insertion hole 17 of the circuit board 16. Inserted and securely held. Then, the main body 11 is electrically connected to the printed wiring board 18 on the circuit board 16. Since the printed wiring board 18 arbitrarily forms conduction paths in the rows and columns of the terminal insertion holes 17 on the circuit board 16, a circuit can be formed according to the conduction paths of the printed wiring board 18. . Even if a circuit change occurs, the change can be easily performed according to the printed wiring board 18 having the changed circuit. Therefore, not only the horizontal direction and the vertical direction but also the degree of freedom in circuit formation can be expanded and productivity can be improved.

また、本発明の一実施形態である端子構造によれば、本体部１１が回路基板１６の端子挿通孔１７に挿入されることで、プレスフィット部１４が端子挿通孔１７に圧接挿着されると同時に、当接部１５が一方のコネクタハウジング３０に当接してそれ以上の挿入が阻止され、他方コネクタハウジング３２の端子孔３３内に突起１２ａが圧入固定される。これにより、端子１０がプリント配線板１８に電気的に接続されるために、半田付け等の接合手段を用いることなく、機械的な組み付けのみで電気的な接続を行うことができる。   Moreover, according to the terminal structure which is one embodiment of the present invention, the press-fit portion 14 is press-fitted into the terminal insertion hole 17 by inserting the main body portion 11 into the terminal insertion hole 17 of the circuit board 16. At the same time, the contact portion 15 contacts one connector housing 30 to prevent further insertion, and the protrusion 12 a is press-fitted and fixed in the terminal hole 33 of the other connector housing 32. Thereby, since the terminal 10 is electrically connected to the printed wiring board 18, it is possible to perform electrical connection only by mechanical assembly without using a joining means such as soldering.

また、本発明の一実施形態である端子構造によれば、本体部１１の先端側の第１外部接続部１２を回路基板１６の端子挿通孔１７に挿通することで、先端側の第１外部接続部１２を一方のコネクタハウジング３０に組み付け、回路基板１６を挟んで他方のコネクタハウジング３２を一方のコネクタハウジング３０に組み付けることで、基端側の第２外部接続部１３を他方のコネクタハウジング３２に組み付けることができる。これにより、回路基板１６に対する単一方向の組み込みを行えるために、工数の減少を図って生産性の向上を図ることができる。   In addition, according to the terminal structure according to the embodiment of the present invention, the first external connection portion 12 on the distal end side of the main body portion 11 is inserted into the terminal insertion hole 17 of the circuit board 16, thereby The connecting portion 12 is assembled to one connector housing 30, and the other connector housing 32 is assembled to one connector housing 30 with the circuit board 16 interposed therebetween, whereby the second external connecting portion 13 on the base end side is connected to the other connector housing 32. Can be assembled. As a result, since the circuit board 16 can be integrated in a single direction, man-hours can be reduced and productivity can be improved.

なお、本発明は、前述した実施形態に限定されるものではなく、適宜、変形、改良等が自在である。例えば、端子の数は、この端子構造が適用される車種毎の回路構成に応じて適宜設定されるために、何ら限定されるものではない。   In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. For example, the number of terminals is not limited at all because it is appropriately set according to the circuit configuration for each vehicle type to which this terminal structure is applied.

また、回路基板上の端子挿通孔端縁に当接する接続部を設けることで、プリント配線板１８上の導電ランドと電気的に接続させることができ、プレスフィット部との接続に加えて、通電経路を付加することができるので、通電容量を増加させることができる。   Further, by providing a connection portion that contacts the edge of the terminal insertion hole on the circuit board, it can be electrically connected to the conductive land on the printed wiring board 18, and in addition to the connection with the press-fit portion, energization Since a route can be added, the current carrying capacity can be increased.

また、回路基板としては、図示した単一構造のものに代えて、複数の回路基板を積層させた複数層のものを用いても良い。もちろん、その場合にも、回路基板接続部がプリント配線板に電気的に接続される。   Moreover, as a circuit board, it may replace with the thing of the single structure shown in figure, and the thing of the several layer which laminated | stacked the several circuit board may be used. Of course, also in this case, the circuit board connecting portion is electrically connected to the printed wiring board.
