Description

この発明は中継用コネクタ、特に成形配線板とソレノイドとを電気的に接続する際に用いて便利なコネクタに関するものである。   The present invention relates to a relay connector, and more particularly to a connector convenient for use in electrically connecting a molded wiring board and a solenoid.

自動車の変速機の内部に配置された配線板においては、電線を用いてコネクタで接続するのが普通である。しかしながら、近年の自動車の変速機内には、環境対応等の要請で、配置される電気部品の数が増加しており、それに伴い価格は上昇する傾向にある。   In a wiring board arranged inside a transmission of an automobile, it is usual to connect with a connector using an electric wire. However, in recent automobile transmissions, the number of electrical components to be arranged is increasing due to demands for environmental measures and the like, and the price tends to increase accordingly.

一方、コストダウンの要請もますます強くなっており、他の部品での価格低減を図り、全体としての価格上昇を抑制しなければならず、電線の代わりに成形配線板を用いて組立性を改善し、作業コストを低減化し、これにより価格上昇を抑えることも試みられている。   On the other hand, there is an increasing demand for cost reductions, and it is necessary to reduce the price of other parts and to suppress the overall price increase. Attempts have also been made to improve and reduce operating costs, thereby suppressing price increases.

一般的に、コネクタにおいては、電気的接続を確実にする為にロック機構を必要とするが、成形配線板との接続の際には、電線との接続の場合と異なり、成形配線板の形態上の特質から、従来のロック機構はそのままでは用いることは困難であった。   In general, a connector requires a locking mechanism to ensure electrical connection. However, when connecting to a molded wiring board, the form of the molded wiring board is different from the case of connecting to an electric wire. Due to the above characteristics, it has been difficult to use the conventional locking mechanism as it is.

つまり、図１に示す様な、主に電線１７との接続するのに用いるコネクタ１９においては、ソレノイドなどに嵌合する端面１４の反対側の端面１５の周囲には使用可能な空間が多く存在しているので、この空間を利用してロックバネ１６を設置することが可能であるが、電線１７に代えて成形配線板を用いる場合には、その空間に成形配線板が位置してしまう為、ロックバネ１６の為の空間を確保することは困難で、従来の電線タイプのコネクタをそのまま成形配線板との接続に用いるのはむずかしかった。   That is, as shown in FIG. 1, in the connector 19 mainly used for connection with the electric wire 17, there is a lot of usable space around the end face 15 on the opposite side of the end face 14 fitted to the solenoid or the like. Therefore, it is possible to install the lock spring 16 using this space, but when using a molded wiring board instead of the electric wire 17, the molded wiring board is located in that space. It is difficult to secure a space for the lock spring 16, and it has been difficult to use a conventional electric wire type connector as it is for connection to a molded wiring board.

本発明者は、自動車の変速機内などで成形配線板とソレノイドとを電気的に接続する際に多く使用される中継コネクタに関する上記従来の問題点を解決すべく研究を行った結果、ロックバネを延伸させる為の空間が乏しい成形配線板との接続の際にも、ロックバネのバネ性を十分に確保し、確実にロックできる様にしたコンパクトな中継コネクタを開発することに成功し、本発明としてここに提案するものである。   The present inventor conducted research to solve the above-mentioned conventional problems related to the relay connector that is often used when electrically connecting a molded wiring board and a solenoid in an automobile transmission or the like. As a result, the lock spring was extended. We have succeeded in developing a compact relay connector that secures the spring property of the lock spring and allows it to be securely locked even when connected to a molded wiring board with insufficient space for This is what we propose.

略直方体状をなした軟質合成樹脂製の本体の長手方向両端に開口部を有し、本体内に設置されている端子と外部の電気部品の端子とを接触させることにより、一対の電気部品同士を電気的に接続する中継用コネクタにおいて、本体の上面上方に、一方の端面から上方に立上った後、本体上面から浮いた状態で長手方向に延伸され、長手方向中央付近で左右に分岐し、斜め下方に向かって弯曲して本体側面に達する略Ｔ字形平面形状を呈した帯状のロックバネを本体上部に一体的に設けると共に、該ロックバネの上面にストッパー用凸部を形成して上記課題を解決した。   A pair of electrical components is formed by having openings at both ends in the longitudinal direction of a soft synthetic resin main body having a substantially rectangular parallelepiped shape, and bringing the terminals installed in the main body into contact with the terminals of external electrical components. In the relay connector for electrical connection, after rising upward from one end surface above the upper surface of the main body, it is extended in the longitudinal direction while floating from the upper surface of the main body, and branches to the left and right near the center in the longitudinal direction. A belt-shaped lock spring having a substantially T-shaped planar shape that bends obliquely downward and reaches the side of the main body is integrally provided on the upper portion of the main body, and a stopper convex portion is formed on the upper surface of the lock spring. Solved.

この発明に係る中継用コネクタは、電線を介在させた電気部品同士の接続にも勿論用いることができるが、ソレノイドと成形配線板との電気的接続に用いる場合には、本体の上方に形成されているロックバネを指や治具などで下方に押さえ込みながら、ソレノイドの接続用凹穿部に本体の脚部が立上っている側の端面を挿入してストッパー用凸部をソレノイドの上面に形成されている係合用透孔に嵌め込み、本体とソレノイドとを結合させると共に、もう一方の端面を成形配線板の接続用凹穿部に差し込んで成形配線板と結合させ、ソレノイドと成形配線板との電気的接続を行う。
この際、この中継用コネクタにおいては、ロックバネは左右に分岐されているので、成形配線板にその本体を差し込んだとき、ロックバネが邪魔になることはなく、ソレノイドとのロックも確実に保持させることができる。又、ロックバネの長さが短いにもかかわらず、バネ性が良好なので、コネクタ本体の小型化が可能で、自動車の変速機内への電気部品の高密度での組込みが現実できる。更には、部品点数を増加させずにロック機能を満足させることができ、ソレノイド作動時の移動エネルギーを受けても電気的接続が損なわれることはなく、接続信頼性も十分に確保することができる。しかも、電線を介在させた接続にも使用可能で、汎用性にすぐれ、高い実用性を有している。 The relay connector according to the present invention can of course be used to connect electrical components with electric wires interposed therebetween, but when used for electrical connection between a solenoid and a molded wiring board, the relay connector is formed above the main body. While pressing the lock spring down with a finger or jig, insert the end face on the side where the leg of the main unit rises into the concave connection part of the solenoid to form the convex part for the stopper on the top face of the solenoid The main body and the solenoid are connected to each other, and the other end surface is inserted into the connecting concave hole of the molded wiring board to be connected to the molded wiring board. Make electrical connections.
At this time, in this relay connector, since the lock spring is branched to the left and right, the lock spring does not get in the way when the main body is inserted into the molded wiring board, and the lock with the solenoid is securely held. Can do. Further, although the length of the lock spring is short, the spring property is good, so that the connector body can be miniaturized, and electrical components can be incorporated into the transmission of an automobile at high density. Furthermore, the locking function can be satisfied without increasing the number of parts, and the electrical connection is not impaired even when the moving energy is applied when the solenoid is operated, and the connection reliability can be sufficiently secured. . In addition, it can be used for connection with an electric wire interposed between them and has excellent versatility and high practicality.

コネクタ本体上面に一体的に設けられている帯状のロックバネを中央で左右に分岐させてＴ字形平面形状にすることにより、ロックバネ全体の長さを短縮させ、成形配線板などに差し込んだ際にロックバネに干渉しない様にした点に最大の特徴が存する。   The length of the entire lock spring is shortened by branching the belt-shaped lock spring provided integrally on the upper surface of the connector body to the left and right in the center to make it a T-shaped flat shape. The greatest feature exists in the point which did not interfere with.

図２はこの発明に係る中継用コネクタの実施例１の斜視図である。図中１は中継用コネクタの本体であり、絶縁性を有する軟質合成樹脂を素材として略直方体状の外観を呈し、その長手方向両端から軸芯に沿って空胴２が形成されており、この空胴２内には接続用端子が軸芯と平行に位置し、ソレノイド４及び成型配線板５にそれぞれ形成されている接続用凹穿部６内の接続用端子７と結合せしめることにより、ソレノイド４と成形配線板５とを電気的に接続する様になっている。
なお、これら構成は、接続用コネクタとしては一般的なものであり、特段目新しいものではない。 FIG. 2 is a perspective view of Embodiment 1 of the relay connector according to the present invention. In the figure, reference numeral 1 denotes a relay connector body, which has a substantially rectangular parallelepiped appearance made of a soft synthetic resin having an insulating property, and a cavity 2 is formed along the axis from both longitudinal ends thereof. A connecting terminal is located in the cavity 2 in parallel with the axis of the cavity 2, and is connected to a connecting terminal 7 in a connecting concave portion 6 formed in the solenoid 4 and the molded wiring board 5, respectively. 4 and the molded wiring board 5 are electrically connected.
In addition, these structures are general as a connector for connection, and are not especially new.

一方、本体１のソレノイド４に接続される側の端面１８の上部からは、帯状のロックバネ８の脚部９が上方に向って立上っており、該脚部９は上部において円弧状に弯曲し、バネ本体１０に接続しており、バネ本体１０は本体１の上方において成形配線板５の方向に向って略平行に延設され、長手方向中央付近において、横方向に分岐して下方に向かってそれぞれ円弧状に弯曲した後、本体１の上面側部から外側に向かって突設された一対の腕材１１，１１に接続されている。   On the other hand, from the upper part of the end face 18 on the side connected to the solenoid 4 of the main body 1, the leg part 9 of the band-shaped lock spring 8 rises upward, and the leg part 9 bends in an arc shape at the upper part. The spring body 10 is connected to the spring body 10 in a direction substantially parallel to the direction of the molded wiring board 5 above the body 1, and is branched laterally downward in the vicinity of the center in the longitudinal direction. After being bent in a circular arc shape, they are connected to a pair of arm members 11, 11 protruding outward from the upper surface side of the main body 1.

つまり、ロックバネ８は図２に示す様に、上方から見て、Ｔ字形の平面形状を呈しており、脚部９、バネ本体１０、脚材１１は軟質合成樹脂により、いずれも本体１と一体的に形成され、上下方向に十分なバネ性を有していることになる。又、このロックバネ８のバネ本体１０の中央部の上面には小さな立方体状のストッパー用凸部１２が一体的に形成されており、ソレノイド４の接続用凹穿部６の上面に設けられている四角形状の係合用透孔１３に係合させられる様になっている。   That is, as shown in FIG. 2, the lock spring 8 has a T-shaped planar shape when viewed from above, and the leg portion 9, the spring body 10, and the leg material 11 are all made of a soft synthetic resin and are all integrated with the body 1. Therefore, it has sufficient spring property in the vertical direction. Further, a small cube-shaped stopper convex portion 12 is integrally formed on the upper surface of the central portion of the spring body 10 of the lock spring 8, and is provided on the upper surface of the connecting concave hole 6 of the solenoid 4. It is made to engage with the rectangular through hole 13 for engagement.

この実施例は、上記の通りの構成を有するものであり、電線を介在させた接続にも勿論用いることができるが、ソレノイド４と成形配線板５との電気的接続に用いる場合には、本体１の上方に形成されているロックバネ８を指や治具などで下方に押さえ込みながら、ソレノイド４の接続用凹穿部６に本体１の脚部９が立上っている側の端面１８を挿入してストッパー用凸部１２を係合用透孔１３に嵌め込み、本体１とソレノイド４とを結合させると共に、もう一方の端面を成形配線板５の接続用凹穿部６に差し込んで成形配線板５と係合させ、ソレノイド４と成形配線板５との電気的接続を行う。
この際、この中継用コネクタにおいては、ロックバネ８は左右に延伸されているので、成形配線板５にその本体１を差し込んだとき、ロックバネ８が邪魔になることはなく、ソレノイド４とのロックを確実に保持させることができる。ロックバネ８の長さが短いにもかかわらず、バネ性が良好なので、コネクタ本体１の小型化が可能で、自動車の変速機内への電気部品の高密度での組込みが実現できる。
更に、部品点数を増加させずに、ロック機能を満足させることができ、ソレノイド作動時の移動エネルギーを受けても電気的接続が損なわれることはなく、接続信頼性も十分に確保することが可能である。
又、電線を介在させた接続にも当然用いることができるので、すぐれた汎用性を有している。 This embodiment has the configuration as described above, and can of course be used for the connection through the electric wires. However, when used for the electrical connection between the solenoid 4 and the molded wiring board 5, the main body The end face 18 on the side where the leg portion 9 of the main body 1 rises is inserted into the connecting concave portion 6 of the solenoid 4 while pressing down the lock spring 8 formed above 1 with a finger or a jig. Then, the stopper convex portion 12 is fitted into the engaging through hole 13 to connect the main body 1 and the solenoid 4, and the other end surface is inserted into the connecting concave portion 6 of the molded wiring board 5 to form the molded wiring board 5. The solenoid 4 and the molded wiring board 5 are electrically connected.
At this time, in this relay connector, since the lock spring 8 is extended to the left and right, the lock spring 8 does not get in the way when the main body 1 is inserted into the molded wiring board 5, and the lock with the solenoid 4 is prevented. It can be reliably held. Although the length of the lock spring 8 is short, the spring property is good, so that the connector main body 1 can be miniaturized, and electrical components can be incorporated at high density into the transmission of an automobile.
Furthermore, the lock function can be satisfied without increasing the number of parts, and the electrical connection will not be damaged even if the movement energy at the time of solenoid operation is received, and the connection reliability can be sufficiently secured. It is.
Moreover, since it can also be used for the connection which interposed the electric wire, it has the outstanding versatility.

自動車の変速機内における電気部品の接続だけでなく、広範囲にわたる電気部品の接続に用いることができる。   It can be used not only for the connection of electrical components in the transmission of an automobile but also for the connection of a wide range of electrical components.

The greatest feature exists in the point which did not interfere with.

図２はこの発明に係る中継用コネクタの実施例１の斜視図である。図中１は中継用コネクタの本体であり、絶縁性を有する軟質合成樹脂を素材として略直方体状の外観を呈し、その長手方向両端から軸芯に沿って空胴２が形成されており、この空胴２内には接続用端子が軸芯と平行に位置し、ソレノイド４及び成型配線板５にそれぞれ形成されている接続用凹穿部６内の接続用端子７と結合せしめることにより、ソレノイド４と成形配線板５とを電気的に接続する様になっている。
なお、これら構成は、接続用コネクタとしては一般的なものであり、特段目新しいものではない。 FIG. 2 is a perspective view of Embodiment 1 of the relay connector according to the present invention. In the figure, reference numeral 1 denotes a relay connector body, which has a substantially rectangular parallelepiped appearance made of a soft synthetic resin having an insulating property, and a cavity 2 is formed along the axis from both longitudinal ends thereof. A connecting terminal is located in the cavity 2 in parallel with the axis of the cavity 2, and is connected to a connecting terminal 7 in a connecting concave portion 6 formed in the solenoid 4 and the molded wiring board 5, respectively. 4 and the molded wiring board 5 are electrically connected.
In addition, these structures are general as a connector for connection, and are not especially new.

一方、本体１のソレノイド４に接続される側の端面１８の上部からは、帯状のロックバネ８の脚部９が上方に向って立上っており、該脚部９は上部において円弧状に弯曲し、バネ本体１０に接続しており、バネ本体１０は本体１の上方において成形配線板５の方向に向って略平行に延設され、長手方向中央付近において、横方向に分岐して下方に向かってそれぞれ円弧状に弯曲した後、本体１の上面側部から外側に向かって突設された一対の腕材１１，１１に接続されている。   On the other hand, from the upper part of the end face 18 on the side connected to the solenoid 4 of the main body 1, the leg part 9 of the band-shaped lock spring 8 rises upward, and the leg part 9 bends in an arc shape at the upper part. The spring body 10 is connected to the spring body 10 in a direction substantially parallel to the direction of the molded wiring board 5 above the body 1, and is branched laterally downward in the vicinity of the center in the longitudinal direction. After being bent in a circular arc shape, they are connected to a pair of arm members 11, 11 protruding outward from the upper surface side of the main body 1.

つまり、ロックバネ８は図２に示す様に、上方から見て、Ｔ字形の平面形状を呈してお
り、脚部９、バネ本体１０、脚材１１は軟質合成樹脂により、いずれも本体１と一体的に形成され、上下方向に十分なバネ性を有していることになる。又、このロックバネ８のバネ本体１０の中央部の上面には小さな立方体状のストッパー用凸部１２が一体的に形成されており、ソレノイド４の接続用凹穿部６の上面に設けられている四角形状の係合用透孔１３に係合させられる様になっている。 That is, as shown in FIG. 2, the lock spring 8 has a T-shaped planar shape when viewed from above, and the leg portion 9, the spring body 10, and the leg material 11 are all made of a soft synthetic resin and are all integrated with the body 1. Therefore, it has sufficient spring property in the vertical direction. Further, a small cube-shaped stopper convex portion 12 is integrally formed on the upper surface of the central portion of the spring body 10 of the lock spring 8, and is provided on the upper surface of the connecting concave hole 6 of the solenoid 4. It is made to engage with the rectangular through hole 13 for engagement.

この実施例は、上記の通りの構成を有するものであり、電線を介在させた接続にも勿論用いることができるが、ソレノイド４と成形配線板５との電気的接続に用いる場合には、本体１の上方に形成されているロックバネ８を指や治具などで下方に押さえ込みながら、ソレノイド４の接続用凹穿部６に本体１の脚部９が立上っている側の端面１８を挿入してストッパー用凸部１２を係合用透孔１３に嵌め込み、本体１とソレノイド４とを結合させると共に、もう一方の端面を成形配線板５の所定箇所に形成されている透孔からその内部に差し込んで成形配線板５と係合させ、ソレノイド４と成形配線板５との電気的接続を行う。
この際、この中継用コネクタにおいては、ロックバネ８は左右に延伸されているので、成形配線板５にその本体１を差し込んだとき、ロックバネ８が邪魔になることはなく、ソレノイド４とのロックを確実に保持させることができる。ロックバネ８の長さが短いにもかかわらず、バネ性が良好なので、コネクタ本体１の小型化が可能で、自動車の変速機内への電気部品の高密度での組込みが実現できる。
更に、部品点数を増加させずに、ロック機能を満足させることができ、ソレノイド作動時の移動エネルギーを受けても電気的接続が損なわれることはなく、接続信頼性も十分に確保することが可能である。
又、電線を介在させた接続にも当然用いることができるので、すぐれた汎用性を有している。 This embodiment has the configuration as described above, and can of course be used for the connection through the electric wires. However, when used for the electrical connection between the solenoid 4 and the molded wiring board 5, the main body The end face 18 on the side where the leg portion 9 of the main body 1 rises is inserted into the connecting concave portion 6 of the solenoid 4 while pressing down the lock spring 8 formed above 1 with a finger or a jig. Then, the stopper convex portion 12 is fitted into the engaging through hole 13 to connect the main body 1 and the solenoid 4, and the other end surface is inserted into the inside from the through hole formed at a predetermined position of the molded wiring board 5. The solenoid 4 and the molded wiring board 5 are electrically connected by being inserted and engaged with the molded wiring board 5.
At this time, in this relay connector, since the lock spring 8 is extended to the left and right, the lock spring 8 does not get in the way when the main body 1 is inserted into the molded wiring board 5, and the lock with the solenoid 4 is prevented. It can be reliably held. Although the length of the lock spring 8 is short, the spring property is good, so that the connector main body 1 can be miniaturized, and electrical components can be incorporated at high density into the transmission of an automobile.
Furthermore, the lock function can be satisfied without increasing the number of parts, and the electrical connection will not be damaged even if the movement energy at the time of solenoid operation is received, and the connection reliability can be sufficiently secured. It is.
Moreover, since it can also be used for the connection which interposed the electric wire, it has the outstanding versatility.

自動車の変速機内における電気部品の接続だけでなく、広範囲にわたる電気部品の接続に用いることができる。   It can be used not only for the connection of electrical components in the transmission of an automobile but also for the connection of a wide range of electrical components.
