Description

本発明は、電気コネクタにおけるコンタクトの接触構造に関するものである。   The present invention relates to a contact structure of a contact in an electrical connector.

従来、電気コネクタにおけるコンタクト同士の接触構造において、一方のコンタクトの接触領域の接触側表面１１に、直線状の溝が例えば図６（Ａ），（Ｂ）に示すように、十字状やＸ状に交差させた凹部１１ａ，１１ｂを設けたものが知られている（特許文献１，２参照）。このような構成により安定した電気的接続を得るようにしている。   Conventionally, in a contact structure of contacts in an electrical connector, a linear groove is formed on the contact side surface 11 of the contact area of one contact, for example, as shown in FIGS. 6 (A) and 6 (B). There is known one provided with recesses 11a and 11b crossing each other (see Patent Documents 1 and 2). With such a configuration, a stable electrical connection is obtained.

特許公開２００６−２２８６６９号公報Japanese Patent Publication No. 2006-228669 国際公開ＷＯ２００８／００１４５９号公報International Publication WO2008 / 001459

しかし、従来の電気コネクタにおけるコンタクトの接触構造では、溝の深さを一定にしている。この凹部を形成する工程において、その深さを調整することが困難であり、深すぎると凹を入れた後のコンタクト接触部を曲げる工程で、コンタクトにクラックが入るおそれがある。また、この凹部を形成する際に、２回に分けて凹みを入れるので、凹部が重なる箇所においては応力が集中してダメージを受けクラックが入りやすくなる。このように、使用するコンタクト材料やコンタクト接触部の曲げ等によってクラックの入りやすさが異なり、よってコンタクトの生産性が劣るという課題がある。
本発明に係る電気コネクタにおけるコンタクトの接触構造は、このような課題を解決するために提案されたものである。 However, in the contact contact structure in the conventional electrical connector, the depth of the groove is constant. In the step of forming the recess, it is difficult to adjust the depth. If the depth is too deep, the contact may be cracked in the step of bending the contact contact portion after the recess is formed. Further, when forming the concave portion, the concave portion is formed in two steps, so that stress concentrates on the portion where the concave portion overlaps, and damage is easily generated. Thus, there is a problem that the ease of cracking varies depending on the contact material used, the bending of the contact contact portion, etc., and therefore the productivity of the contact is inferior.
The contact contact structure in the electrical connector according to the present invention has been proposed in order to solve such a problem.

本発明に係る電気コネクタにおけるコンタクトの接触構造の上記課題を解決して目的を達成するための要旨は、レセプタクルコネクタに固定して併設される雌コンタクトと、前記レセプタクルコネクタに嵌合するプラグコネクタに前記雌コンタクトの位置に対応して固定し併設される雄コンタクトとのうち一方のコンタクトの接触部は、当該コンタクトの長手方向においてコンタクト基部から一体にして支持されるとともに、前記コンタクトの板厚方向に屈曲されて接触側に向けて凸部にされ、且つ、当該接触部の接触側表面に十字型，Ｘ型若しくはＶ型に交差する凹部が形成されて成る接触構造において、前記交差する凹部のそれぞれの深さが、異なる深さで形成されていることである。   The gist for achieving the object by solving the above-described problems of the contact contact structure in the electrical connector according to the present invention is to provide a female contact fixedly attached to the receptacle connector and a plug connector fitted to the receptacle connector. The contact portion of one of the male contacts fixed and provided corresponding to the position of the female contact is integrally supported from the contact base in the longitudinal direction of the contact, and the thickness direction of the contact In a contact structure that is bent into a convex portion toward the contact side, and a concave portion that intersects the cross shape, the X shape, or the V shape is formed on the contact side surface of the contact portion. Each depth is formed at a different depth.

本発明の電気コネクタにおけるコンタクトの接触構造によれば、接触部に設けられた交差する凹部がその深さを違えて交わり、クラックの発生が抑えられ、生産性が向上するものである。その結果、使用できるコンタクト材料の種類も拡大し、汎用性が向上するものである。また、交差する凹部の深さが異なることで、接触部における接触信頼性が向上する。そして、コンタクト設計時の自由度が向上し挿抜時の接触抵抗力が減少する。   According to the contact contact structure in the electrical connector of the present invention, intersecting concave portions provided in the contact portion intersect with each other at different depths, and generation of cracks is suppressed, thereby improving productivity. As a result, the types of contact materials that can be used are expanded and versatility is improved. Moreover, the contact reliability in a contact part improves because the depth of the recessed part which cross | intersects differs. And the freedom degree at the time of contact design improves, and the contact resistance force at the time of insertion / extraction reduces.

本発明に係る電気コネクタにおけるコンタクト１の接触構造は、図１（Ａ）〜（Ｄ）に示すように、レセプタクルコネクタ（図示せず）に固定して併設される雌コンタクトと、前記レセプタクルコネクタに嵌合するプラグコネクタ（図示せず）に前記雌コンタクトの位置に対応して固定し併設される雄コンタクトとのうち一方のコンタクト１の接触部において実現される。   As shown in FIGS. 1A to 1D, the contact structure of the contact 1 in the electrical connector according to the present invention includes a female contact fixedly attached to a receptacle connector (not shown), and the receptacle connector. This is realized at a contact portion of one contact 1 among a male contact fixedly attached to a plug connector (not shown) to be fitted in correspondence with the position of the female contact.

そして、前記コンタクト１の長手方向においてコンタクト基部２（プリント基板などに半田付けされる）から一体にして支持されるとともに、前記コンタクト１の板厚方向に屈曲されて接触側に向けて凸部にされ、且つ、当該接触部の接触側表面３にＸ型に交差する凹部４，５が形成されている。   The contact 1 is supported integrally from the contact base 2 (soldered to a printed circuit board or the like) in the longitudinal direction of the contact 1, and is bent in the plate thickness direction of the contact 1 to be convex toward the contact side. And the recessed part 4 and 5 which cross | intersects X type | mold is formed in the contact side surface 3 of the said contact part.

前記凹部４，５は、前記交差する凹部のそれぞれの深さが、異なる深さで形成されている。   The concave portions 4 and 5 are formed with different depths of the intersecting concave portions.

コンタクト１は、例えば、レセプタクルのコンタクト収納部に固定して併設される雌コンタクトである。また、これに接触する相手側の雄コンタクトの接触部の面は、平坦である。   The contact 1 is, for example, a female contact that is fixedly attached to the contact storage portion of the receptacle. Moreover, the surface of the contact part of the other male contact which contacts this is flat.

前記凹部は、金型により加工するものであるが、深さは、図２（Ｂ），（Ｃ）に示すように、凹部４の深さｄ１が深く、凹部５の深さｄ２は浅い。その実施例としては、前記凹部４の深さｄ１が約９μｍで、凹部５の深さｄ２が約３μｍである。この場合、深い方の前記凹部４を先に加工し、その後に、前記凹部５を加工する。   The concave portion is processed by a mold, and as shown in FIGS. 2B and 2C, the depth d1 of the concave portion 4 is deep and the depth d2 of the concave portion 5 is shallow. In this embodiment, the depth d1 of the recess 4 is about 9 μm, and the depth d2 of the recess 5 is about 3 μm. In this case, the deeper recess 4 is processed first, and then the recess 5 is processed.

この第１実施例に係るコンタクト１では、その電気的接触性能を他のコンタクトと比較すると、凹部深さｄ１＝約９μｍ，ｄ２＝約１．５μｍ、同じ深さのコンタクトｄ１＝ｄ２＝約３μｍ、凹部のないコンタクト、とした場合に、より良い方を＞記号で表すと、凹部深さｄ１＝約９μｍ，ｄ２＝約３μｍ＞凹部深さｄ１＝約９μｍ，ｄ２＝約１．５μｍ＞同じ深さのコンタクトｄ１＝ｄ２＝約３μｍ＞凹部のないコンタクト、となる。 In the contact 1 according to the first embodiment, when compared with other contacts, the recess depth d1 = about 9 μm , d2 = about 1.5 μm, and the contact d1 = d2 = about the same depth. In the case of 3 μm and a contact without a concave portion, the better one is represented by a symbol> concave portion depth d1 = about 9 μm, d2 = about 3 μm> recessed portion depth d1 = about 9 μm , d2 = about 1.5 μm > Contact of the same depth d1 = d2 = about 3 μm> Contact without recess.

図３乃至図４に示すように、コンタクト１ａに、十字型の凹部６，７を設けたものである。前記凹部６がの深さが深く、凹部７の深さは浅い。その実施例としては、第１実施例と同様である。また、深さの深い方の前記凹部６を先に加工し、その後に、前記凹部７を加工する。   As shown in FIGS. 3 to 4, the contact 1a is provided with cross-shaped recesses 6 and 7. FIG. The recess 6 is deep and the recess 7 is shallow. The embodiment is the same as the first embodiment. Moreover, the said recessed part 6 of the deeper one is processed first, and the said recessed part 7 is processed after that.

前記実施例１と実施例２とにおいて、各凹部４，５、凹部６，７においては、接触側表面３の断面を見た場合に、図５（Ａ）〜（Ｃ）に示すように、凹部を形成する側壁面８の立ち上がり角度θが、凹部底面から拡開させて９０°以上大きく開いた角度で形成した場合と、次第に９０°に近づけて形成した場合の、電気的接触性能を比較してみる。そこで、接触する相手側のコンタクト表面にフラックスを被膜させて、所定の押圧力で接触させる。前記フラックスの膜厚は、一例として約３μｍである。   In the first embodiment and the second embodiment, in each of the concave portions 4 and 5 and the concave portions 6 and 7, when the cross section of the contact side surface 3 is viewed, as shown in FIGS. 5 (A) to (C), Comparison of electrical contact performance between the case where the rising angle θ of the side wall surface 8 forming the concave portion is widened by 90 ° or more from the bottom surface of the concave portion, and when gradually rising to 90 °. Try it. Therefore, a flux is coated on the contact surface of the counterpart to be contacted, and contact is made with a predetermined pressing force. The film thickness of the flux is about 3 μm as an example.

前記角度θが９０°に近いほど、前記角部Ｒのフラックスを貫通する接触力が少ない。即ち、角部Ｒにおいて、極端に微小な半径ｒにしなくても、十分な接触信頼性を得られるものである。これにより、コンタクト設計の自由度が広がるようになる。更に、角部Ｒの先端を極端な微小ｒにしないことで、挿抜時の接触抵抗力も少なくすることができる。   The closer the angle θ is to 90 °, the less the contact force penetrating the flux at the corner R. That is, sufficient contact reliability can be obtained even if the corner portion R does not have an extremely small radius r. This increases the degree of freedom in contact design. Furthermore, the contact resistance force at the time of insertion / extraction can be reduced by not making the tip of the corner portion R extremely small.

上記実施例で、凹部４，５、凹部６，７を十字型，Ｘ型に交差させて形成したものを示したが、これに限らずＶ型等に交差する凹部にしても良い。   In the above-described embodiment, the concave portions 4 and 5 and the concave portions 6 and 7 are formed so as to intersect with the cross shape and the X shape.

このようにして、従来の同じ深さの凹部をＸ型状等に形成出来なかったコンタクト材料であっても、本発明の形状には形成可能であり、汎用性が向上することになる。   In this manner, even a conventional contact material in which a concave portion having the same depth cannot be formed in an X shape or the like can be formed in the shape of the present invention, and versatility is improved.

本発明のコンタクトの接触構造は、電気的コンタクトの接触部において、広く応用して採用することができるものである。   The contact contact structure of the present invention can be widely applied and employed in the contact portion of an electrical contact.
