Description

本考案は、電気コネクター内に配置される、対接コネクターと電気的に接続するための弾性ピンに関し、特に、弾性を有する収縮可能なピンに関する。 The present invention relates to an elastic pin disposed in an electrical connector and electrically connected to a mating connector, and more particularly to an elastic contractible pin.

図1は、従来技術の電気コネクターと対接コネクターの立体図である。このような電気コネクターとは、プラグ式電気コネクターであり、通常、携帯電話やパーソナル・デジタル・アシスタント或いは充電器等に適用されて、充電や信号転送することに供する。電気コネクター８には、絶縁ケーシング８２と、複数の弾性ピン８４と、ケーブル８３とが含有され、弾性ピン８４は、絶縁ケーシング８２に収納され、絶縁ケーシング８２の先端から露出し、ケーブル８３は、絶縁ケーシング８２の末端に配置され、弾性ピン８４に電気的に接続される。電気コネクター８は、対接コネクター９と、対応し、対接コネクター９には、複数の固定される平面ピン９２がある。 FIG. 1 is a three-dimensional view of a conventional electrical connector and a contact connector. Such an electrical connector is a plug-type electrical connector, and is usually applied to a mobile phone, a personal digital assistant, a charger, or the like to be used for charging or signal transfer. The electrical connector 8 includes an insulating casing 82, a plurality of elastic pins 84, and a cable 83. The elastic pins 84 are accommodated in the insulating casing 82 and exposed from the tip of the insulating casing 82. It is disposed at the end of the insulating casing 82 and is electrically connected to the elastic pin 84. The electrical connector 8 corresponds to the contact connector 9, which has a plurality of fixed planar pins 92.

図2は、従来技術の弾性ピンの前面図である。接触の安定性や信頼性を確保するため、弾性ピン８４は、弾性的に、対接コネクター９の該平面ピン９２に当接するように、設置される。弾性ピン８４には、固定保持部８５と、弾性アーム８６と、接触部８７と、が含有される。その中、固定保持部８５は、絶縁ケーシング８２の内壁と、干渉し合い、弾性アーム８６は、固定保持部８５の左右から、湾曲的に上へ伸びて、弾性的に、対接コネクター９の平面ピン９２に当接する。 FIG. 2 is a front view of a conventional elastic pin. In order to ensure the stability and reliability of the contact, the elastic pin 84 is installed so as to elastically contact the flat pin 92 of the contact connector 9. The elastic pin 84 includes a fixed holding portion 85, an elastic arm 86, and a contact portion 87. Among them, the fixed holding portion 85 interferes with the inner wall of the insulating casing 82, and the elastic arm 86 extends curvedly upward from the left and right of the fixed holding portion 85, and elastically, It contacts the flat pin 92.

しかし、電気コネクター８は、対接コネクター９に接続される時、平面ピン９２は、弾性ピン１３に対して、一方向の力を生成することに加え、斜めの方向の力も生成される。また、接続された後、電気コネクター８の重量により、垂下する現象が起こることによって、弾性ピン８４は、傾斜的に対接コネクター９の平面ピン９２に当接する状態になる。しかし、上記の従来技術である弾性アーム８６は、比較的に強い縦方向の弾性力しか生成できず、他の方向においての弾性力が、弱いものであるため、弾性ピン８４が受ける力の全ては、垂直方向に集中し、そのため、弾性疲労が容易に発生する。一方、弾性ピン８４を収納するための縦方向にやや長い収納空間がある構造が必要となるため、電気コネクター８のサイズが大きくなる。 However, when the electrical connector 8 is connected to the contact connector 9, the planar pin 92 generates a force in one direction in addition to a force in one direction against the elastic pin 13. Further, after the connection, the phenomenon that the electric connector 8 hangs down due to the weight of the electric connector 8 causes the elastic pin 84 to come into contact with the flat pin 92 of the contact connector 9 in an inclined manner. However, the above-described conventional elastic arm 86 can generate only a relatively strong longitudinal elastic force, and the elastic force in the other direction is weak. Are concentrated in the vertical direction, so that elastic fatigue easily occurs. On the other hand, since a structure having a slightly longer storage space in the vertical direction for storing the elastic pin 84 is required, the size of the electrical connector 8 is increased.

接触部８７には、斜め方向から力が印加されると、弾性アーム８６の上部が、変形し、従来の技術においては、弾性アーム８６の上部において、厚さを大きくして、厚い底部８８を形成するため、弾性が劣化するだけでなく、材料のコストも高くなる。 When a force is applied to the contact portion 87 from an oblique direction, the upper portion of the elastic arm 86 is deformed. In the conventional technique, the thickness is increased at the upper portion of the elastic arm 86 so that the thick bottom portion 88 is formed. As a result of the formation, not only the elasticity is degraded, but the cost of the material is also increased.

また、弾性アーム８６には、一つの方向(縦方向)について、変形を吸収する能力しかないため、応力が集中し、大きな力を受ける事になる。弾性アーム８６は、容易に弾性疲労するため、通常、非常に高い強度を有する材料を適用することにより、高い弾性という要請を満足する。従来の技術は、通常、高価のベリリウム銅合金（Be
Cu）を適用することにより、硬度や強度を向上させるため、コストが高くなる。また、弾性アーム８６に、湾曲する回数が多くて、長さがより長くなるため、抵抗が大きくなり、通信の品質に悪影響を与えることになる。 Further, since the elastic arm 86 has only the ability to absorb deformation in one direction (longitudinal direction), stress concentrates and receives a large force. Since the elastic arm 86 is easily elastically fatigued, the demand for high elasticity is usually satisfied by applying a material having very high strength. Conventional techniques typically use expensive beryllium copper alloys (Be
By applying Cu), the hardness and strength are improved, which increases the cost. Further, since the elastic arm 86 is bent many times and becomes longer, the resistance is increased and the communication quality is adversely affected.

以上のことから分かるように、上記の従来の弾性ピンには、実際の実用上、不便や欠点があるので、改善すべくものである。 As can be seen from the above, the above-described conventional elastic pins have inconveniences and disadvantages in actual practical use and should be improved.

本考案人は、上記の欠点が改善できると分かって、鋭意に研究し、また、学理的な運用を合わせて、設計が合理的であり、また、有効に、上記の欠点を改善できる本考案を提案した。 The inventor knows that the above-mentioned drawbacks can be improved, researches intensively, and combines the scientific operation with a rational design, and can effectively improve the above-mentioned disadvantages. Proposed.

本考案は、多方向に接続力を生成し、良い接触信頼性を確保できるだけでなく、より安い銅合金を使用することにより、生産コストを低減できる、弾性ピンを提供する。 The present invention provides an elastic pin that not only generates a connection force in multiple directions and ensures good contact reliability, but also can reduce production costs by using a cheaper copper alloy.

本考案の主な目的は、多方向の接続力が生成して、良い接触信頼性を確保でき、また、力を分散させて、弾性疲労を低減する弾性ピンを提供する。 A main object of the present invention is to provide an elastic pin that can generate a multidirectional connection force to ensure good contact reliability, and also distributes the force to reduce elastic fatigue.

本考案の他の目的は、抵抗を低下させて、信号の品質を向上する、弾性ピンを提供する。 Another object of the present invention is to provide an elastic pin that reduces resistance and improves signal quality.

本考案の更に他の目的は、より安い銅合金を適用することにより、生産のコストを低減できる、弾性ピンを提供する。 Still another object of the present invention is to provide an elastic pin that can reduce the cost of production by applying a cheaper copper alloy.

本考案に係わる弾性ピンは、上記の目的を達成するため、電気コネクター内に収容されて、対接コネクターに電気的に接続され、下へ垂直に伸びる半田付けピンである固定保持部と、当該固定保持部の一側から上へ伸びる縦方向湾曲部がある弾性アームと当該縦方向湾曲部の一側に位置する少なくとも二つの横方向湾曲部とを有する弾性アームと、当該弾性アームの末端に形成され、当該電気コネクターの上部に位置するスリットから露出する接触部と、を有する。 In order to achieve the above object, an elastic pin according to the present invention is housed in an electrical connector, electrically connected to the contact connector, and a fixing holding portion which is a soldering pin extending vertically downward, An elastic arm having a longitudinally curved portion extending upward from one side of the fixed holding portion, an elastic arm having at least two laterally curved portions positioned on one side of the longitudinally curved portion, and an end of the elastic arm A contact portion formed and exposed from a slit located at an upper portion of the electrical connector.

図面を参照しながら、本考案のより良い実施例について詳しく説明するが、ここで、説明するものは、本考案を説明するためのものだけであり、本考案に係わる実用新案登録の範囲を制限するものではない。 The preferred embodiments of the present invention will be described in detail with reference to the drawings. However, what is described here is only for explaining the present invention, and limits the scope of utility model registration related to the present invention. Not what you want.

図3及び図４は、それぞれが、本考案の弾性ピンの立体図と、本考案の弾性ピンが組み立てられる電気コネクターの断面図である。本考案の弾性ピン１は、電気コネクター２内に収容され、対接コネクター３（図5参照）に電気的に接続される。弾性ピン１には、固定保持部１２と、弾性アーム１４と、接触部１６と、が含有される。電気コネクター２には、絶縁ケーシング２２と、絶縁ケーシング２２の上部に形成される複数のスリット２４と、が含有される。本実施例において、電気コネクター２には、更に、底部に設けられる回路基板２６があり、回路基板２６は、弾性ピン１を固定保持する絶縁板体であってもいい。絶縁ケーシング２２には、複数の弾性ピン１を収納するための収納空間２３が、形成される。対接コネクター３には、複数の対接端子３２がある。 3 and 4 are a three-dimensional view of the elastic pin of the present invention and a cross-sectional view of the electrical connector in which the elastic pin of the present invention is assembled, respectively. The elastic pin 1 of the present invention is housed in an electrical connector 2 and is electrically connected to a contact connector 3 (see FIG. 5). The elastic pin 1 includes a fixed holding portion 12, an elastic arm 14, and a contact portion 16. The electrical connector 2 contains an insulating casing 22 and a plurality of slits 24 formed in the upper portion of the insulating casing 22. In the present embodiment, the electrical connector 2 further includes a circuit board 26 provided at the bottom, and the circuit board 26 may be an insulating plate that fixes and holds the elastic pin 1. A storage space 23 for storing the plurality of elastic pins 1 is formed in the insulating casing 22. The contact connector 3 has a plurality of contact terminals 32.

固定保持部１２は、回路基板２６に半田付けるための、下へ垂直に伸びる、半田付けピン１３である。半田付けピン１３は、固定保持部１２の底部の中央にでなく、固定保持部１２の底部の側辺に設置され、これにより、複数の弾性ピン１は、逆方向に並列するように、回路基板２６に半田付けされ、また、半田付けピン１３は、半田付けをより容易にするため、交差のように設置され、図４において、半田付けピン１３’のようである。半田付けピン１３は、回路基板２６に半田付けされなく、直接的にケーブルに半田付けされてもいい。 The fixed holding part 12 is a soldering pin 13 extending vertically downward for soldering to the circuit board 26. The soldering pin 13 is installed not on the center of the bottom of the fixed holding part 12 but on the side of the bottom of the fixed holding part 12, so that the plurality of elastic pins 1 are arranged in parallel in opposite directions. The soldering pins 13 are soldered to the board 26, and are installed like a cross to make the soldering easier, and are like soldering pins 13 'in FIG. The soldering pin 13 may be directly soldered to the cable without being soldered to the circuit board 26.

本実施例において、固定保持部１２の底部の縁に、複数の互いに対称する凹槽１２２が設けられ、その中、半田付けピン１３の基部の両側には、それぞれ凹槽１２２が設けられ、これにより、半田付けピン１３においての基部の強度を強くしながら、半田付けピンを、異なる位置に変化できる。その中、固定保持部１２の自由端には、外へ向かう突出１２４が形成され、また、固定保持部１２と弾性アーム１４と接続する位置にも、外へ向かう突出１２６が形成され、上記の両突出１２４、１２６により、弾性ピン１と絶縁ケーシング２２の内壁とが、干渉し合うため、収納空間２３内に固定される。 In this embodiment, a plurality of symmetrical concave tubs 122 are provided on the edge of the bottom of the fixed holding portion 12, and the concave tubs 122 are respectively provided on both sides of the base of the soldering pin 13. Thus, the soldering pin can be changed to a different position while increasing the strength of the base portion of the soldering pin 13. Among them, an outward protrusion 124 is formed at the free end of the fixed holding portion 12, and an outward protrusion 126 is also formed at a position where the fixed holding portion 12 and the elastic arm 14 are connected. Since both the protrusions 124 and 126 cause the elastic pin 1 and the inner wall of the insulating casing 22 to interfere with each other, they are fixed in the storage space 23.

弾性アーム１４には、固定保持部１２の一側から上へ伸びる縦方向湾曲部１５と、縦方向湾曲部１５の一側に位置する少なくとも二つの横方向湾曲部１７と、がある。本考案に係わる弾性アーム１４は、多方向に、対接コネクター３に当接する弾性力を提供し、縦方向湾曲部１５は、側面へ向かう弾性力を提供し、二つの横方向湾曲部１７は、湾曲により互いに接続することによって、垂直方向の弾性力を提供する。 The elastic arm 14 includes a longitudinal bending portion 15 extending upward from one side of the fixed holding portion 12 and at least two lateral bending portions 17 located on one side of the longitudinal bending portion 15. The elastic arm 14 according to the present invention provides an elastic force that abuts the contact connector 3 in multiple directions, the longitudinal bending portion 15 provides an elastic force toward the side surface, and the two lateral bending portions 17 By connecting to each other by bending, it provides a vertical elastic force.

接触部１６は、弾性アーム１４の末端に形成され、また、電気コネクター２の上部のスリット２４から露出する。 The contact portion 16 is formed at the end of the elastic arm 14 and is exposed from the slit 24 at the top of the electrical connector 2.

図5は、本考案に係わる弾性ピンが組み立てられる、対接コネクターに挿設される、電気コネクターの断面図である。本実施例において、弾性アーム１４の末端は、下へ突出する当接部１７２であり、接触部１６が力を受けて下へ移動すると、当接部１７２は、横方向湾曲部１７に当接して、比較的に短い信号転送経路を提供するため、信号の品質の向上に更に有利になる。本実施例において、接触部１６の底端には、弾性アーム１４の末端に対応する、内へ向かう欠け口１６２が形成されるため、元の弾性が維持できるだけでなく、横方向湾曲部１７を下ヘの圧力を減少させ、変形量を低減し、力が、当接部１７２に直接に作用し、また、材料の節約もできる。 FIG. 5 is a cross-sectional view of an electrical connector inserted into a contact connector in which an elastic pin according to the present invention is assembled. In this embodiment, the end of the elastic arm 14 is a contact portion 172 that protrudes downward, and when the contact portion 16 receives force and moves downward, the contact portion 172 contacts the lateral bending portion 17. Thus, since a relatively short signal transfer path is provided, it is further advantageous in improving the signal quality. In the present embodiment, the bottom end of the contact portion 16 is formed with an inward cutout 162 corresponding to the end of the elastic arm 14, so that not only the original elasticity can be maintained, but also the laterally curved portion 17 is provided. The downward pressure is reduced, the amount of deformation is reduced, the force acts directly on the contact portion 172, and material can be saved.

本考案に係わる弾性ピン１は、上記の構造により、対接コネクター３との圧接力を分散して、弾性疲労を減少し、また、対接コネクター３に対する接触信頼性が向上できる。同時に、本考案において、湾曲方式により、弾性アーム１４の長さが、従来技術の長さより、短いため、抵抗が低下されて、信号の品質が向上される。 With the above structure, the elastic pin 1 according to the present invention disperses the pressure contact force with the contact connector 3, reduces elastic fatigue, and improves the contact reliability with respect to the contact connector 3. At the same time, in the present invention, due to the bending method, the length of the elastic arm 14 is shorter than the length of the prior art, so the resistance is lowered and the signal quality is improved.

図6は、本考案に係わる弾性ピン材料ベルトの前面図である。本考案の弾性ピン１は、弾性ピン材料ベルト４を分断して得られ、弾性ピン材料ベルト４は、金属シートをプレスして製作され、上へ伸びる複数の接続部４２を有する材料ブリッジ４１が含有され、その上に、複数の弾性ピン１が形成される。弾性ピン１の固定保持部１２は、接続部４２が接続される。本考案の湾曲方式により、より良い、多方向の弾性力が生成されるため、本考案において、より安い、一般の銅合金で同様な効果が得られ、コストの低減を大幅に実現できる。 FIG. 6 is a front view of an elastic pin material belt according to the present invention. The elastic pin 1 of the present invention is obtained by dividing the elastic pin material belt 4. The elastic pin material belt 4 is manufactured by pressing a metal sheet, and a material bridge 41 having a plurality of connecting portions 42 extending upward is provided. A plurality of elastic pins 1 are formed thereon. The connecting portion 42 is connected to the fixed holding portion 12 of the elastic pin 1. Since a better multi-directional elastic force is generated by the bending method of the present invention, the same effect can be obtained with a cheaper general copper alloy in the present invention, and the cost can be greatly reduced.

以上の説明は、ただ、本考案のより良い実施例であり、本考案の登録範囲は、それによって、制限される物ではなく、また、本考案の登録範囲においての、等価な変化や変更も、本考案の範囲に含まれる。 The above description is merely a better embodiment of the present invention, and the registration scope of the present invention is not limited thereby, and equivalent changes and modifications within the registration scope of the present invention are also possible.
