ところで、先行技術文献にあっては、1つの電子部品のリード端子をソケットに嵌合されている端子弾性保持部に対して嵌合し、その後にプリント基板の裏面から導出されているリード端子をプリント基板のパターンに端子弾性保持部の一部と共に半田付け固定するものであり、1つの取付装置に対しては1つの電子部品しか取付けできないものであった。   By the way, in the prior art document, the lead terminal of one electronic component is fitted to the terminal elastic holding portion fitted in the socket, and then the lead terminal led out from the back surface of the printed circuit board is used. A part of the terminal elastic holding portion is soldered and fixed to the printed circuit board pattern, and only one electronic component can be attached to one attachment device.

すなわち、1つの電子部品をプリント基板に対して嵩上げした状態でプリント基板に取付けるものであり、複数の電子部品のリード端子を連続して接続して回路を構成するということは不可能なものであった。   That is, one electronic component is attached to the printed circuit board in a raised state with respect to the printed circuit board, and it is impossible to configure a circuit by continuously connecting lead terminals of a plurality of electronic components. there were.

本発明は前記した問題点を解決せんとするもので、その目的とするところは、プリント基板の導電パターンに半田付け固定した状態において、2つの電子部品のリード端子を直交する方向に半田付けすることができるようにしたので、プリント基板に対して電子部品を直列方向のみならず直交する方向にも半田付け固定でき、従って、プリント基板の設計の自由度が大きくなるプリント基板用端子を提供せんとするにある。   The present invention is intended to solve the above-described problems, and its object is to solder the lead terminals of two electronic components in a direction orthogonal to each other in a state of being soldered and fixed to a conductive pattern of a printed circuit board. As a result, it is possible to solder and fix electronic components to the printed circuit board not only in the series direction but also in the orthogonal direction, thus providing a printed circuit board terminal that increases the degree of freedom in designing the printed circuit board. To be.

本発明のプリント基板用端子は、前記した目的を達成せんとするもので、請求項1の手段は、プリント基板の導電パターンに半田付け固定される台部と、該台部の一辺から起立された起立部と、該起立部の先端から折曲され四隅を起立して鍔部を形成することで電子部品のリード端子を載置する十字状の溝が形成されたリード支持部とから構成したことを特徴とする。   The printed circuit board terminal of the present invention achieves the above-described object, and the means of claim 1 is erected from a base portion soldered to the conductive pattern of the printed circuit board and one side of the base portion. And a lead support portion formed with a cross-shaped groove on which the lead terminal of the electronic component is placed by standing up the four corners and forming a collar portion by bending from the tip of the standing portion. It is characterized by that.

請求項2の手段は、前記した請求項1において、前記リード支持部の前記十字状の溝が自動吸着機の吸着ノズルにより吸着が可能なように平坦面に形成されていることを特徴とする。   According to a second aspect of the present invention, in the first aspect, the cross-shaped groove of the lead support portion is formed on a flat surface so as to be sucked by a suction nozzle of an automatic suction machine. .

請求項3の手段は、前記した請求項1において、前記台部をプリント基板の導電パターンに半田付けした際に余分な半田を逃がすための開口部が形成されていることを特徴とする。   According to a third aspect of the present invention, in the first aspect, an opening is formed for releasing excess solder when the base portion is soldered to the conductive pattern of the printed circuit board.

本発明は前記したように、プリント基板の導電パターンに台部が半田付けされたリード支持部に十字状の溝が形成されたリード支持部を形成したので、電子部品のリード端子を直線方向のみならず直交方向、あるいは、導電パターンに対する半田付け方向を他の端子に対して斜め位置に半田付けすることで斜め方向にリード端子を取付けることが可能となり、導電パターンに対して電子部品をあらゆる方向に取付けることができ、従って、プリント基板のパターン設計の自由度が大きくなる。   In the present invention, as described above, since the lead support portion in which the cross-shaped groove is formed is formed in the lead support portion in which the base portion is soldered to the conductive pattern of the printed circuit board, the lead terminal of the electronic component is arranged only in the linear direction. In addition, it is possible to attach the lead terminal in an oblique direction by soldering the soldering direction with respect to the other direction, or in an orthogonal direction, or in an oblique direction with respect to the other terminals. Therefore, the degree of freedom in pattern design of the printed circuit board is increased.

また、リード支持部の十字状の溝が自動吸着機の吸着ノズルにより吸着が可能なように平坦面に形成することにより、自動吸着機の吸着ノズルに吸着してプリント基板の導電パターン上に移動して半田付けが行えるので、プリント基板への半田付けを自動化によって正確、かつ、迅速に取付けることができる。   In addition, the cross-shaped groove of the lead support part is formed on a flat surface so that it can be adsorbed by the adsorption nozzle of the automatic adsorption machine, so that it is adsorbed by the adsorption nozzle of the automatic adsorption machine and moves onto the conductive pattern on the printed circuit board Since soldering can be performed, the soldering to the printed circuit board can be performed accurately and quickly by automation.

さらに、台部をプリント基板の導電パターンに半田付けした際に余分な半田を逃がすための開口部を形成することで、余分な半田が側面方向に流れて他の導電パターンと接続されるのを防止できる等の効果を有するものである。   Furthermore, when the base is soldered to the conductive pattern of the printed circuit board, an opening is formed to allow excess solder to escape, so that the excess solder flows in the lateral direction and is connected to other conductive patterns. It has effects such as prevention.

以下、本発明に係るプリント基板用端子Aの構造を図面と共に説明する。
1は大きな銅板から打ち抜きプリント基板の導電パターンに半田付けするための台部にして、四角形状に形成されており中央に開口部11が形成されている。この開口部11は導電パターンに半田付けした時に余分な半田が開口部11から上方に流れるようにし、外周側に流れ他の導電パターンと短絡しないようにするものである。
Hereinafter, the structure of the printed circuit board terminal A according to the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a base for punching out from a large copper plate and soldering to a conductive pattern of a printed circuit board, which is formed in a square shape and has an opening 11 formed in the center. This opening 11 is used to prevent excess solder from flowing upward from the opening 11 when soldered to the conductive pattern, and to flow to the outer peripheral side so as not to be short-circuited with other conductive patterns.

2は前記台部1の一辺から延長された起立部にして、先端に向かって幅が狭く形成され先端側が弾性を有する形状となっている。3は前記起立部2の先端に延長されたリード支持部にして、4隅がプレス加工によって切り起こされ鍔部31となっている。この鍔部31によって形成された中心部分は十字状の溝32となっている。そして、溝32の底面は平坦面となっており、自動吸着機の吸着ノズルによる吸着が可能な形状となっている。   Reference numeral 2 denotes an upright part extended from one side of the base part 1 and is formed in a shape having a narrow width toward the tip and having elasticity at the tip. Reference numeral 3 denotes a lead support portion extended to the tip of the upright portion 2, and four corners are cut and raised by pressing to form a flange portion 31. A central portion formed by the flange 31 is a cross-shaped groove 32.

In this state, the bottom surface, which is the flat surface of the groove 32 of the lead support portion 3, is moved while being sucked by the suction nozzle of the automatic suction machine, and is placed on a desired conductive pattern on the printed circuit board. Since this conductive pattern is coated with solder paste, the printed circuit board terminal A is temporarily fixed.

このように複数のプリント基板用端子Aを導電パターンに載置した状態で高熱炉を通過させることで、プリント基板用端子Aはプリント基板の導電パターンに半田付け状態となる。   In this way, by passing the high temperature furnace with a plurality of printed circuit board terminals A placed on the conductive pattern, the printed circuit board terminals A are soldered to the conductive pattern of the printed circuit board.

そして、1つのプリント基板用端子Aに対して2つのプリント基板用端子A′を直交する方向に配置することで、2つの電子部品Bは直交した導電パターンに接続されることとなる。また、1つのプリント基板用端子Aに対して他のプリント基板用端子(図示せず)を導電パターンC2(プリント基板用端子Aにおけるリード支持部3の溝32の直線方向とは異なる位置)に半田付けした場合であっても、リード端子B1を変形させることで導電パターンC1,C2との間に電子部品Bを半田付けすることが可能となる。   By disposing the two printed circuit board terminals A ′ in the direction orthogonal to the one printed circuit board terminal A, the two electronic components B are connected to the orthogonal conductive patterns. Further, another printed circuit board terminal (not shown) is placed on one printed circuit board terminal A in a conductive pattern C2 (a position different from the linear direction of the groove 32 of the lead support portion 3 in the printed circuit board terminal A). Even when soldered, the electronic component B can be soldered between the conductive patterns C1 and C2 by deforming the lead terminal B1.
