Description

本発明は、FPCに対する端子の接続構造に関する。   The present invention relates to a connection structure of terminals to an FPC.

プリント基板に端子を接続する際には、プリント基板のスルーホールに端子を挿通して半田付けしていた。しかしながら、半田接合時に電子部品に熱の影響が及ぶのを防止するために、下記の特許文献1の電子機器のように、半田接合を行わずに端子接続を行うことが考えられている。   When connecting the terminal to the printed circuit board, the terminal is inserted into the through hole of the printed circuit board and soldered. However, in order to prevent an electronic component from being affected by heat at the time of solder bonding, it is considered to perform terminal connection without performing solder bonding as in the electronic device disclosed in Patent Document 1 below.

下記の特許文献1の電子機器は、カメラモジュールの突起電極に拡径した係止部を備えている。基板には、大径部と小径部とを並べて構成された貫通孔が形成され、貫通孔の周囲には端子が形成されている。カメラモジュールは、突起電極の係止部が貫通孔の大径部に挿入された後、係止部が小径部内に進入するよう位置合わせされて基板に実装される。突起電極と端子とは、小径部の裏面に係止されることで接触する。   The electronic device disclosed in Patent Document 1 includes a locking portion whose diameter is increased on the protruding electrode of the camera module. The substrate has a through hole formed by arranging a large diameter portion and a small diameter portion, and a terminal is formed around the through hole. The camera module is mounted on the substrate after the locking portion of the protruding electrode is inserted into the large-diameter portion of the through hole and then aligned so that the locking portion enters the small-diameter portion. The protruding electrode and the terminal come into contact with each other by being locked to the back surface of the small diameter portion.

しかしながら、特許文献1の方法では、突起電極を貫通孔の大径部に挿入した後、係止部が小径部内に進入するようカメラモジュールの位置決めを行う必要があり、接続作業に手間がかかった。   However, in the method of Patent Document 1, it is necessary to position the camera module so that the engaging portion enters the small diameter portion after the protruding electrode is inserted into the large diameter portion of the through hole, which takes time and labor. .

本発明は斯かる課題に鑑みてなされたもので、半田接合を行わず簡単な作業でPFCに端子を接続できる端子接続構造を提供することを目的とする。   The present invention has been made in view of such a problem, and an object thereof is to provide a terminal connection structure capable of connecting a terminal to a PFC by a simple operation without performing solder bonding.

このような目的を達成するために、本発明の端子接続構造は、コネクタの一面に配設されたFPCに対する端子接続構造であって、端子の先端から長手方向に延びたスリットと、前記一面に開口し、前記端子が挿入される端子孔と、該端子孔の底面に突設され、前記端子の前記スリットに嵌合する突起と、該突起と対向する位置に開口し、前記突起に前記スリットを嵌合させた端子により拡開される端子挿通孔と、該端子挿通孔の周縁に形成されて、前記端子挿通孔を拡開した前記端子に接続されるランドとを備え、前記端子挿通孔の周縁は、前記端子の挿入にしたがって前記スリットが開拡すると、前記端子孔の内部方向に屈曲し、かつ弾性力によって前記突起とともに前記端子を挟持していることを特徴とする。
また、本発明は、前記突起が、前記端子挿通孔を通して前記端子孔の外部に突出していることを特徴とする。
In order to achieve such an object, the terminal connection structure of the present invention is a terminal connection structure for an FPC disposed on one surface of a connector, and includes a slit extending in the longitudinal direction from the tip of the terminal, An opening, a terminal hole into which the terminal is inserted, a protrusion projecting from the bottom surface of the terminal hole, fitting into the slit of the terminal, opening to a position facing the protrusion, and the slit into the protrusion A terminal insertion hole that is expanded by a terminal fitted with the terminal, and a land that is formed at a peripheral edge of the terminal insertion hole and that is connected to the terminal having the terminal insertion hole expanded , the terminal insertion hole When the slit is expanded according to the insertion of the terminal, the peripheral edge of the terminal is bent in the inner direction of the terminal hole, and the terminal is held together with the protrusion by an elastic force .
Further, the present invention is characterized in that the projection protrudes outside the terminal hole through the terminal insertion hole.

本発明によれば、端子の先端を端子挿通孔を通して端子孔に挿入するという簡単な作業で、半田接合を行わずにFPCに端子を接続できる。   According to the present invention, the terminal can be connected to the FPC without performing solder bonding by a simple operation of inserting the tip of the terminal into the terminal hole through the terminal insertion hole.

以下、図面を参照して、本発明の一実施形態を説明する。
本実施形態の端子接続構造は、図1に示すように、コネクタ2の一面に配設されたFPC(Flexible printed circuits)3に対する端子1の接続構造である。
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the terminal connection structure of the present embodiment is a connection structure of the terminal 1 to an FPC (Flexible Printed Circuits) 3 disposed on one surface of the connector 2.

端子1は、断面方形の棒状を呈しており、先端部にはスリット11を備えている。スリット11は、端子1の先端から端子1の長手方向に延びている。スリット11の先端は拡開している。   The terminal 1 has a bar shape with a square cross section, and has a slit 11 at the tip. The slit 11 extends from the tip of the terminal 1 in the longitudinal direction of the terminal 1. The tip of the slit 11 is expanded.

コネクタ2の一面には、端子1が挿入される端子孔21が開口している。端子孔21の底面には、端子1のスリット11に嵌合する突起22が突設されている。突起22は断面三角形状を呈した板状体である。   A terminal hole 21 into which the terminal 1 is inserted is opened on one surface of the connector 2. A protrusion 22 that fits into the slit 11 of the terminal 1 is provided on the bottom surface of the terminal hole 21. The protrusion 22 is a plate-like body having a triangular cross section.

FPC3の突起22と対向する位置には、端子挿通孔31が開口している。図示しないが、端子挿通孔31の周縁には、ランドが設けられている。   A terminal insertion hole 31 is opened at a position facing the protrusion 22 of the FPC 3. Although not shown, a land is provided on the periphery of the terminal insertion hole 31.

端子1は、図1に矢印で示すように、端子挿通孔31を通して端子孔21に先端から挿入される。端子1の先端のスリット11が、図2に示すように端子孔21の突起22に嵌合すると、スリット11が図2に矢印で示すように拡開され、端子1の先端が分割される。   The terminal 1 is inserted into the terminal hole 21 from the tip through the terminal insertion hole 31 as indicated by an arrow in FIG. When the slit 11 at the tip of the terminal 1 is fitted into the protrusion 22 of the terminal hole 21 as shown in FIG. 2, the slit 11 is expanded as shown by the arrow in FIG. 2, and the tip of the terminal 1 is divided.

スリット11が拡開すると、分割された端子1の先端の周面が端子挿通孔31の周縁に当接して、端子挿通孔31が拡開された状態となる。端子1は、図3に示すように、先端が端子孔21の底面にまで達するまで、端子孔21内に挿入される。   When the slit 11 is expanded, the peripheral surface at the tip of the divided terminal 1 is brought into contact with the peripheral edge of the terminal insertion hole 31 so that the terminal insertion hole 31 is expanded. As shown in FIG. 3, the terminal 1 is inserted into the terminal hole 21 until the tip reaches the bottom surface of the terminal hole 21.

端子挿通孔31の周縁部は、図4に拡大して示すように、端子1により下方に屈曲させられ、FPC3の周縁部の表面が端子1の周面に接触している。このため、FPC3の周縁部の表面に形成されたランドに端子1が接続される。屈曲した端子挿通孔31の周縁部は、図4に矢印で示すように端子1側に弾発力を働かせており、端子挿通孔31と突起22とで端子1が挟持された状態となっている。   As shown in an enlarged view in FIG. 4, the peripheral portion of the terminal insertion hole 31 is bent downward by the terminal 1, and the surface of the peripheral portion of the FPC 3 is in contact with the peripheral surface of the terminal 1. For this reason, the terminal 1 is connected to the land formed on the surface of the peripheral edge of the FPC 3. As shown by an arrow in FIG. 4, the peripheral portion of the bent terminal insertion hole 31 exerts an elastic force toward the terminal 1, and the terminal 1 is sandwiched between the terminal insertion hole 31 and the protrusion 22. Yes.

上述したように、本実施形態の端子1の接続構造では、端子1の先端が端子挿通孔31を通して端子孔21に挿入されて、端子孔21の底面に突設された突起22にスリット11が嵌合すると、スリット11で分割された端子1の先端により端子挿通孔31が拡開され、端子挿通孔31の周縁に形成されたランドに端子1が接続される。   As described above, in the connection structure of the terminal 1 of the present embodiment, the tip of the terminal 1 is inserted into the terminal hole 21 through the terminal insertion hole 31, and the slit 11 is formed in the protrusion 22 protruding from the bottom surface of the terminal hole 21. When fitted, the terminal insertion hole 31 is expanded by the tip of the terminal 1 divided by the slit 11, and the terminal 1 is connected to the land formed at the periphery of the terminal insertion hole 31.

本実施形態によれば、端子1の先端を端子挿通孔31を通して端子孔21に挿入するという簡単な作業で、半田接合を行わずにFPC3に端子1を接続させることができる。   According to the present embodiment, the terminal 1 can be connected to the FPC 3 without performing solder bonding by a simple operation of inserting the tip of the terminal 1 into the terminal hole 21 through the terminal insertion hole 31.

なお、上記実施形態では、突起22の高さがコネクタ2の一面よりも低く、突起22の先端が端子孔21の内部に位置している場合につて説明した。しかしながら、突起22の高さは任意であり、例えば、図5に示すように、端子挿通孔31を通して突起22が端子孔21の外部に突出していてもよい。   In the above embodiment, the case where the height of the protrusion 22 is lower than one surface of the connector 2 and the tip of the protrusion 22 is located inside the terminal hole 21 has been described. However, the height of the protrusion 22 is arbitrary. For example, the protrusion 22 may protrude outside the terminal hole 21 through the terminal insertion hole 31 as shown in FIG.

また、スリット11が端子挿通孔31を拡開させた状態に保つことができるのであれば、突起22及びスリット11の形状も任意である。また、突起22の大きさも任意である。突起22を大きくしてスリット11を大きく拡開させることで、端子1とFPC3との間に位置ずれが生じ難くなり、ランドと端子1との電気的接続の確実性を高めることができる。   Moreover, if the slit 11 can maintain the state which expanded the terminal insertion hole 31, the shape of the processus | protrusion 22 and the slit 11 is also arbitrary. Further, the size of the protrusion 22 is also arbitrary. By enlarging the protrusions 22 and widening the slits 11, misalignment is unlikely to occur between the terminal 1 and the FPC 3, and the reliability of electrical connection between the land and the terminal 1 can be improved.

また、スリット11を突起22に嵌合させた端子1により拡開されて端子1を挟持し、周縁部に形成されたランドを端子1に接続させられるのであれば、端子挿通孔31の形状及び大きさも任意である。また、上記実施形態では、端子1が棒状に形成されている場合について説明したが、先端にスリット11が形成されているのであれば、端子1の形状も任意である。例えば、端子1は、断面円形の棒状体から構成されていてもよい。   Further, if the slit 11 is expanded by the terminal 1 fitted to the protrusion 22 to sandwich the terminal 1 and the land formed at the peripheral portion can be connected to the terminal 1, the shape of the terminal insertion hole 31 and The size is also arbitrary. Moreover, although the said embodiment demonstrated the case where the terminal 1 was formed in rod shape, if the slit 11 is formed in the front-end | tip, the shape of the terminal 1 is also arbitrary. For example, the terminal 1 may be composed of a rod-shaped body having a circular cross section.
