Description

本発明は、各種の電子部品が実装されたプリント配線基板に関する。   The present invention relates to a printed wiring board on which various electronic components are mounted.

プリント配線基板上に電子部品が実装されることによってプリント配線基板上に回路が構成される。この回路と外部の回路等とを相互に接続する必要があるので、プリント配線基板に、リード線が束になったハーネスを接続しなければならない。ハーネスの端部にはコネクタが取り付けられており、このコネクタと対をなすコネクタをプリント配線基板上に実装し、両コネクタを連結することによってハーネスをプリント配線基板上の回路に接続する。   A circuit is configured on the printed wiring board by mounting the electronic component on the printed wiring board. Since it is necessary to mutually connect this circuit and an external circuit or the like, it is necessary to connect a harness in which lead wires are bundled to the printed wiring board. A connector is attached to the end of the harness, and a connector paired with the connector is mounted on the printed wiring board, and the connector is connected to a circuit on the printed wiring board by connecting the two connectors.

ただし、このコネクタを用いる方式であればプリント配線基板上にコネクタを実装しなければならないが、コネクタは比較的大型の部品で有り、プリント配線基板を収納するスペースが狭い場合にはプリント配線基板にコネクタを実装できない場合が生じる。   However, if this connector is used, the connector must be mounted on the printed wiring board, but the connector is a relatively large component, and if the space for housing the printed wiring board is narrow, the printed wiring board is used. In some cases, the connector can not be mounted.

そこで、基板の外縁から突出する端子部を設け、その端子部にプリントされた導電部からなる端子を設け、端子部に係合するコネクタ内の端子と端子部の端子とを電気的に接続するようにしたものが知られいている（例えば、特許文献１参照）。   Therefore, a terminal portion protruding from the outer edge of the substrate is provided, a terminal formed of a conductive portion printed on the terminal portion is provided, and the terminal in the connector engaged with the terminal portion is electrically connected to the terminal of the terminal portion. What was done is known (see, for example, Patent Document 1).

特開平１１−１２６９８５号公報（図１）Unexamined-Japanese-Patent No. 11-126985 (FIG. 1)

上記の構成で、端子部をコネクタに接続した状態でハーネスが引っ張られるなどしてコネクタに外力が作用すると、その外力は端子部に作用し、端子部が破損するおそれがある。そのため、上記特許文献に記載されたものでも、端子部を挟むガイド部を基板と一体に形成し、端子部に作用する外力を分散して軽減するように配慮されている。   In the above configuration, when an external force acts on the connector when the harness is pulled in a state where the terminal portion is connected to the connector, the external force acts on the terminal portion, and the terminal portion may be damaged. Therefore, even in the patent document described above, the guide portions sandwiching the terminal portion are integrally formed with the substrate, and the external force acting on the terminal portion is considered to be dispersed and reduced.

ところが、端子部に作用する外力は低減されるが、外力の多くがガイド部に作用して、ガイド部が破損するという不具合が新たに生じる。   However, although the external force acting on the terminal portion is reduced, most of the external force acts on the guide portion to newly cause a problem that the guide portion is broken.

そこで本発明は、上記の問題点に鑑み、端子部を挟むガイド部が破損しないようにしたプリント配線基板を提供することを課題とする。   Therefore, in view of the above problems, the present invention has an object to provide a printed wiring board in which the guide portions sandwiching the terminal portion are not damaged.

上記課題を解決するために本発明によるプリント配線基板は、板状の基板の外縁から突出する端子部を設け、その端子部にプリントされた導電部からなる端子を設け、端子部に係合するコネクタ内の端子と端子部の端子とを電気的に接続するプリント配線基板において、上記端子部を挟むガイド部を基板と一体に形成し、そのガイド部を補強する導電部をガイド部から基板本体部分にわたってプリントし、さらにその導電部にハンダを被着することによって補強効果を増すようにしたことを特徴とする。 In order to solve the above problems, the printed wiring board according to the present invention is provided with a terminal portion projecting from the outer edge of a plate-like substrate, and a terminal comprising a conductive portion printed on the terminal portion is provided and engaged with the terminal portion In a printed wiring board for electrically connecting a terminal in a connector and a terminal of a terminal portion, a guide portion sandwiching the terminal portion is integrally formed with the substrate, and a conductive portion for reinforcing the guide portion from the guide portion to the substrate body It is characterized in that the reinforcing effect is enhanced by printing over a portion and further applying a solder to the conductive portion .

プリント配線基板上には自由に導電部をプリントすることができるので、回路構成に支障が無いように、ガイド部を補強する導電部をガイド部にプリントすることによって、ガイド部の破損を防止する。   Since the conductive portion can be printed freely on the printed wiring board, damage to the guide portion is prevented by printing the conductive portion reinforcing the guide portion on the guide portion so that there is no hindrance to the circuit configuration. .

なお、上記コネクタの外面には、上記端子部の挿入方向に平行なガイド溝が形成されており、上記端子部にコネクタを係合させる際に、上記ガイド部がガイド溝に挿入され、コネクタと基板との相対移動をガイドすることによって、コネクタが斜めになることを防止して発生する外力が大きくならないようにしてもよい。   A guide groove parallel to the insertion direction of the terminal portion is formed on the outer surface of the connector, and when the connector is engaged with the terminal portion, the guide portion is inserted into the guide groove, and By guiding the relative movement with the substrate, the connector may be prevented from being inclined and the generated external force may not be increased.

以上の説明から明らかなように、本発明は、ガイド部を補強する導電部を設けたので、ガイド部に外力が作用してもガイド部の破損が防止される。   As apparent from the above description, according to the present invention, since the conductive portion for reinforcing the guide portion is provided, even if an external force acts on the guide portion, breakage of the guide portion is prevented.

本発明の一実施の形態の構成を示す図A diagram showing a configuration of an embodiment of the present invention 補強用の導電部の第１の変形例を示す図The figure which shows the 1st modification of the electroconductive part for reinforcement 補強用の導電部の第２の変形例を示す図The figure which shows the 2nd modification of the conductive part for reinforcement

図１を参照して、１は本発明によるプリント配線基板（以下、基板という）であり、その表面には銅箔からなる多数の導電部がプリントされている。この基板１の外縁から外方に突出するように端子部２を設けた。この端子部２には外部のコネクタＣに接続される複数の個所から延設された導電部からなる端子２１が設けられている。従って、この端子部２に外部のコネクタＣを取り付けると、コネクタＣの各リード線が各端子２１に電気的に接続されることになる。この端子部２を挟んで両側に１対のガイド部３を基板１に一体に形成した。   Referring to FIG. 1, reference numeral 1 denotes a printed wiring board (hereinafter referred to as a board) according to the present invention, on the surface of which a large number of conductive parts made of copper foil are printed. The terminal portion 2 was provided to protrude outward from the outer edge of the substrate 1. The terminal portion 2 is provided with a terminal 21 consisting of a conductive portion extended from a plurality of points connected to the external connector C. Therefore, when the external connector C is attached to the terminal portion 2, the lead wires of the connector C are electrically connected to the terminals 21. A pair of guide portions 3 were integrally formed on the substrate 1 on both sides of the terminal portion 2.

一方、コネクタＣの両側面にはガイド溝Ｇが形成されており、コネクタＣを図示のように端子部２に取り付ける際に、ガイド部３の内側部３０がガイド溝Ｇ内に入ってコネクタＣの移動をガイドするようにした。このように構成すると、コネクタＣが端子部２に取り付けられた状態でコネクタＣに対して外力が作用しても、その外力がガイド部３に分散されて、端子部２が破損することが防止される。   On the other hand, guide grooves G are formed on both side surfaces of the connector C, and when the connector C is attached to the terminal portion 2 as illustrated, the inner portion 30 of the guide portion 3 enters the guide groove G To guide the movement of With such a configuration, even if an external force acts on the connector C in a state where the connector C is attached to the terminal portion 2, the external force is dispersed to the guide portion 3 and the terminal portion 2 is prevented from being damaged Be done.

ところが、外力がガイド部３に分散されると、ガイド部３が破損するおそれが新たに生じる。そこで、両ガイド部３にそれぞれ導電部からなる補強部３１，３２を設けて、ガイド部３の機械的強度を増すことによってガイド部３が破損することを防止することとした。なお、両補強部３１，３２は共にいずれの導電部に対しても導通しておらず、他の導電部に対して電気的に絶縁された状態にある。また、各導電部にフローハンダする際に、この補強部３１，３２にもハンダが盛られるので、ハンダによって補強効果が増すことになる。なお、Ｒは導電部のハンダ付けが不要な部分にハンダ付けされないように塗布したレジン膜である。   However, when the external force is dispersed to the guide portion 3, there is a possibility that the guide portion 3 may be damaged. Therefore, reinforcing portions 31 and 32 made of conductive portions are provided in both the guide portions 3 to prevent the guide portion 3 from being damaged by increasing the mechanical strength of the guide portion 3. Both reinforcing portions 31 and 32 are not electrically connected to any of the conductive portions, and are in a state of being electrically insulated from other conductive portions. Further, when the flow soldering is performed on each conductive portion, the reinforcing portions 31 and 32 are filled with the solder, so that the reinforcing effect is increased by the solder. Here, R is a resin film applied so as not to be soldered to a portion where soldering of the conductive portion is unnecessary.

ところで、図１に示したものでは、補強部３１，３２を端子２１と同じ面に設けたが、図２に示すように、端子２１を設けた面に対して反対側の面に補強部３１，３２を設けてもよい。   By the way, although the reinforcement parts 31 and 32 were provided in the same surface as the terminal 21 in what was shown in FIG. 1, the reinforcement part 31 is provided in the surface on the opposite side to the surface which provided the terminal 21 as shown in FIG. , 32 may be provided.

また、図３に示すように、ガイド部３に分散された外力は角部３０ａに集中するので、この角部３０ａを囲うようにＬ字型に補強部３３を形成してもよい。   Further, as shown in FIG. 3, since the external force dispersed in the guide portion 3 is concentrated on the corner portion 30a, the reinforcing portion 33 may be formed in an L shape so as to surround the corner portion 30a.

なお、本発明は上記した形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々の変更を加えてもかまわない。   The present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the present invention.
