Description

本発明は、携帯情報端末機、ノートパソコンなどの情報機器、小型オーディオプレーヤー、小型ディスプレーなどのＡＶ機器、その他の電子機器の内部に組み込まれ、回路基板どうしの間、回路基板と電子部品との間、または機器の外装部品に設けられる導通部と回路基板との間などの種々の接続部品間を含む接続部材間の電気的接続に用いられる弾性コネクタに関する。   The present invention is incorporated in an information device such as a portable information terminal, a notebook personal computer, a small audio player, an AV device such as a small display, and other electronic devices, and between the circuit boards and between the circuit board and the electronic component. The present invention relates to an elastic connector used for electrical connection between connection members including various connection parts such as between or between a conductive portion provided on an exterior part of a device and a circuit board.

回路基板と電子部品の間などを電気的に接続する弾性コネクタには、その一例として図５や図６で示す弾性コネクタ１がある。この弾性コネクタ１は、絶縁性のゴム状弾性体でなる外周部２と、その内側に設けられる弾性導通部３とで円柱体に形成され、その両端面１ａ，１ａに弾性導通部３が露出して、円柱体の管軸方向に導電性を有する部材である。この弾性コネクタ１の弾性導通部３には、ゴム状弾性体中に磁性導電体が配合されたものが用いられている。   As an example of an elastic connector for electrically connecting a circuit board and an electronic component, there is an elastic connector 1 shown in FIGS. This elastic connector 1 is formed in a cylindrical body by an outer peripheral portion 2 made of an insulating rubber-like elastic body and an elastic conducting portion 3 provided on the inner side thereof, and the elastic conducting portion 3 is exposed at both end faces 1a, 1a. And it is a member which has electroconductivity in the pipe-axis direction of a cylindrical body. As the elastic conducting portion 3 of the elastic connector 1, a rubber-like elastic body in which a magnetic conductor is blended is used.

こうした弾性コネクタ１を電子機器に取付けるには、はんだ付けや機械的接合などの固定手段を用いる必要がなく、対向する接点（電極）にそれぞれ端面１ａを接触し圧接することで両接点を簡単に接続することができる。そして外周部２で機器外部からの振動や衝撃を吸収することができ、位置ずれによる接触不良を起こし難くすることができる。さらには、弾性導通部３の摩耗や放電を防止することができ、確実な電気的接続を実現することができる。   In order to attach such an elastic connector 1 to an electronic device, there is no need to use a fixing means such as soldering or mechanical joining, and both the contacts can be easily made by contacting and pressing the end faces 1a to opposing contacts (electrodes). Can be connected. The outer peripheral portion 2 can absorb vibrations and shocks from the outside of the device, and it is possible to make it difficult for poor contact due to misalignment. Furthermore, wear and discharge of the elastic conducting portion 3 can be prevented, and reliable electrical connection can be realized.

この弾性コネクタ１は、例えば、特開２００３−２５７５４２号公報に開示されている。また、複数の弾性導通部が形成されて異方導電性シートとされた例が、例えば、特開２００５−１７８０９２号公報に開示されている。こうした弾性導通部を設けた弾性コネクタ１や異方導電性シートは、効率的な生産、簡易的な作業、高い歩留まりなどを実現できることから金型成形によって製造されている。   This elastic connector 1 is disclosed in, for example, Japanese Patent Application Laid-Open No. 2003-257542. An example in which a plurality of elastic conductive portions are formed as an anisotropic conductive sheet is disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-178092. The elastic connector 1 and the anisotropic conductive sheet provided with such an elastic conducting portion are manufactured by molding because they can realize efficient production, simple work, high yield, and the like.

こうした柱状の弾性コネクタ１は、その底面に比べて高さが十分に低い場合には、安定的に配置することができるが、底面に比べて高さが高い、背の高い形状となると、圧縮時に弾性コネクタ自身が座屈し、回路基板から外れ易くなるだけでなく、接続部材との接触面が傾き導通不良となるおそれがある。
そのため、弾性コネクタを保持するホルダを回路基板または筐体等の接続部材側に設けて、そのホルダ内に弾性コネクタをはめ込む改良がなされているが、マウンターによる搬送で弾性コネクタを回路基板にセットするため、ホルダ内に弾性コネクタをはめ込むことは困難であった。また、マウンターによらずに手作業でセットする場合も同様であった。さらに、筐体等の接続部材側にホルダを含めて設計するにはスペース上の課題や設計上の制約があり、ホルダを簡単には設けることができないといった欠点があった。 Such a columnar elastic connector 1 can be stably disposed when its height is sufficiently lower than its bottom surface, but when it becomes a tall shape with a height higher than its bottom surface, it is compressed. In some cases, the elastic connector itself buckles and becomes easily detached from the circuit board, and the contact surface with the connection member may be tilted, resulting in poor conduction.
For this reason, a holder for holding the elastic connector is provided on the side of the connection member such as a circuit board or a housing, and the elastic connector is fitted into the holder. However, the elastic connector is set on the circuit board by carrying with a mounter. Therefore, it is difficult to fit the elastic connector in the holder. The same was true when setting manually without using a mounter. In addition, there is a problem in terms of space and design restrictions in designing a housing including a holder on the side of a connection member such as a housing, and there is a drawback that the holder cannot be easily provided.

以上のような従来技術を背景としてなされたのが本発明である。すなわち、本発明の目的は、弾性コネクタを実装する接続部材間が比較的離れた場合であっても座屈し難い弾性コネクタを得ることにある。   The present invention has been made against the background of the prior art as described above. That is, an object of the present invention is to obtain an elastic connector that is difficult to buckle even when the connection members for mounting the elastic connector are relatively separated from each other.

上記目的を達成すべく以下に構成する弾性コネクタを提供する。
すなわち、絶縁性のゴム状弾性体でなるベース部と、導電方向に導電体が数珠繋ぎに配向する導通部と、ベース部を補強する硬質材でなる補強芯材とを一体に備えており、接続部材間に挟持されて、これら接続部材どうしを相互に導通接続する柱状の弾性コネクタについて、補強芯材は環状の鍔部を有するハット形状の金属板からなり、導通部はその一端が補強芯材の頂部と連通しており、ベース部は補強芯材と導通部のそれぞれの外周面を被覆しており、導通部の他端と前記金属板の鍔部が接続部材に接触可能であって、ベース部に被覆された導通部が補強芯材を設けた部分から突出する弾性接続部位と、補強芯材を有する形状保持部位とを構成することを特徴とする弾性コネクタである。 In order to achieve the above object, an elastic connector configured as follows is provided.
That is, it is integrally provided with a base portion made of an insulating rubber-like elastic body, a conduction portion in which the conductors are connected in a row in the conductive direction, and a reinforcing core material made of a hard material that reinforces the base portion. For the columnar elastic connector sandwiched between the members and electrically connecting these connecting members to each other, the reinforcing core material is a hat-shaped metal plate having an annular flange, and one end of the conductive portion is a reinforcing core material. The base portion covers the outer peripheral surfaces of the reinforcing core member and the conducting portion, and the other end of the conducting portion and the flange portion of the metal plate can contact the connecting member, The elastic connector is characterized in that the conductive portion covered by the base portion constitutes an elastic connection portion protruding from a portion provided with the reinforcing core member and a shape holding portion having the reinforcing core member.

絶縁性のゴム状弾性体でなるベース部と、導電方向に導電体が数珠繋ぎに配向する導通部と、ベース部を補強する硬質材でなる補強芯材とを一体に備えたため、回路基板や筐体等の接続部材間が比較的離れている場合であっても、接続部材側にホルダ等の余分な部位を設けることなく、座屈し難い弾性コネクタとすることができる。
補強芯材が環状の鍔部を有するハット形状の金属板からなるため、この補強芯材を設けた部分はベース部を補強することができるとともに、導通部と連通して導通させることができる。また、ハット形状の内側を中空とすることで軽量な弾性コネクタとすることができる。環状の鍔部を有するため、この環状の鍔部を露出させることで、ハンダ付け面とすることができる。さらに、ハット形状の頂部を有するため導通部の端部と十分な導通接続を行うことができる。 Since the base part made of an insulating rubber-like elastic body, the conduction part in which the conductors are oriented in a row in a conductive direction, and the reinforcing core made of a hard material that reinforces the base part, the circuit board and the housing are integrated. Even when the connection members such as the body are relatively separated from each other, an elastic connector that is difficult to buckle can be obtained without providing an extra portion such as a holder on the connection member side.
Since the reinforcing core member is made of a hat-shaped metal plate having an annular flange portion, the portion provided with the reinforcing core member can reinforce the base portion and can be electrically connected to the conducting portion. Moreover, it can be set as a lightweight elastic connector by making the inside of a hat shape hollow. Since it has an annular collar part, it can be set as a soldering surface by exposing this annular collar part. Furthermore, since it has a hat-shaped top portion, sufficient conduction connection can be made with the end portion of the conduction portion.

導通部はその一端を金属製の補強芯材の頂部と連通することができるため、導通部と補強芯材とを導通させることが可能となる。これにより、接続部材との接点を補強芯材とすることができ、弾性コネクタの一端にハンダ付けすることが可能となる。
ベース部は補強芯材と導通部のそれぞれの外周面を被覆しているため、所定の端面以外では導電部分が被覆され他部品との絶縁状態を確保することができる。また、補強芯材と導通部とをベース部で一体にすることができる。
導通部の他端と金属板の鍔部が接続部材に接触可能であるため、金属製の補強芯材を導電部分として担わせることができる。 Since the one end of the conducting portion can communicate with the top of the metal reinforcing core, the conducting portion and the reinforcing core can be conducted. Thereby, a contact with a connection member can be used as a reinforcing core, and it becomes possible to solder to one end of an elastic connector.
Since the base portion covers the outer peripheral surfaces of the reinforcing core member and the conductive portion, the conductive portion is covered except for the predetermined end surface, and an insulation state from other parts can be ensured. Further, the reinforcing core member and the conducting portion can be integrated with each other at the base portion.
Since the other end of the conducting portion and the collar portion of the metal plate can contact the connecting member, a metal reinforcing core can be carried as the conductive portion.

ベース部に被覆された導通部が補強芯材を設けた部分から突出する弾性接続部位を構成するため、このベース部に被覆された導通部の部分は圧縮を受けると伸縮することができ、接続部材間に圧着させて、確実な導通を図ることができる。また、補強芯材を有する形状保持部位を構成するため、形状保持部位の部分では圧縮を受けても伸縮させないことができる。そのため、弾性コネクタの必要以上の伸縮を防止し、弾性コネクタ自体の座屈を防止することができる。   Since the conductive part covered by the base part constitutes an elastic connection part protruding from the part provided with the reinforcing core material, the part of the conductive part covered by this base part can expand and contract when subjected to compression, It is possible to achieve reliable conduction by pressing between the members. In addition, since the shape holding portion having the reinforcing core material is configured, the portion of the shape holding portion cannot be expanded or contracted even when subjected to compression. Therefore, the elastic connector can be prevented from expanding and contracting more than necessary, and the elastic connector itself can be prevented from buckling.

また、絶縁性のゴム状弾性体でなるベース部と、導電方向に導電体が数珠繋ぎに配向する導通部と、ベース部を補強する硬質材でなる補強芯材とを一体に備えており、接続部材間に挟持されて、これら接続部材どうしを相互に導通接続する柱状の弾性コネクタについて、補強芯材は円筒状の硬質板からなり、導通部はその円筒内を貫通しており、ベース部は導通部の外周面と補強芯材の外周面を被覆しており、さらに補強芯材を設けた一端側には金属箔層を有しており、導通部の一端と前記金属箔層が接続部材に接触可能であって、ベース部に被覆された導通部が補強芯材を設けた部位から突出する弾性接続部位と、補強芯材を有する形状保持部位とを構成することを特徴とする弾性コネクタを提供する。   In addition, a base part made of an insulating rubber-like elastic body, a conducting part in which the conductors are oriented in a daisy chain in the direction of conduction, and a reinforcing core made of a hard material that reinforces the base part are provided integrally. About the columnar elastic connector that is sandwiched between the members and electrically connects these connecting members to each other, the reinforcing core is made of a cylindrical hard plate, the conductive portion penetrates the cylinder, and the base portion is The outer peripheral surface of the conducting portion and the outer peripheral surface of the reinforcing core material are covered, and a metal foil layer is provided on one end side where the reinforcing core material is provided, and the one end of the conducting portion and the metal foil layer are connected to each other. The elastic connector is characterized in that the conductive portion covered with the base portion constitutes an elastic connection portion projecting from a portion provided with the reinforcing core member and a shape holding portion having the reinforcing core member. I will provide a.

補強芯材が円筒状の硬質板からなるため、導通部を被覆するベース部の中に補強芯材を含ませることができる。そのため、導通部における導電体の配向状態に影響を与えることなくベース部を補強することができる。換言すれば、導通部は補強芯材と交差せず、補強芯材の円筒内を貫通することができるため、補強芯材の影響を受けずに導通状態を保持することができる。
ベース部は導通部の外周面と補強芯材の外周面を被覆するため、所定の端面以外では導電部分が被覆され他部品との絶縁状態を確保することができる。また、補強芯材と導通部とをベース部で一体にすることができる。
さらに補強芯材を設けた一端側には金属箔層を設けたため、金属箔層にハンダ付けすることが可能であり、導通部の一端と前記金属箔層が接続部材に接触可能であるため、金属製の金属箔層を導電部分として担わせることができる。 Since the reinforcing core member is made of a cylindrical hard plate, the reinforcing core member can be included in the base portion that covers the conducting portion. Therefore, the base portion can be reinforced without affecting the orientation state of the conductor in the conduction portion. In other words, the conducting portion does not intersect with the reinforcing core material and can penetrate through the cylinder of the reinforcing core material, so that the conducting state can be maintained without being affected by the reinforcing core material.
Since the base portion covers the outer peripheral surface of the conducting portion and the outer peripheral surface of the reinforcing core member, the conductive portion is covered except for the predetermined end surface, and an insulating state from other parts can be ensured. Further, the reinforcing core member and the conducting portion can be integrated with each other at the base portion.
Furthermore, since the metal foil layer is provided on one end side where the reinforcing core material is provided, it is possible to solder to the metal foil layer, and since one end of the conductive portion and the metal foil layer can contact the connection member, A metal metal foil layer can be carried as a conductive portion.

ベース部に被覆された導通部が補強芯材を設けた部位から突出する弾性接続部位を構成するため、このベース部に被覆された導通部の部分は圧縮を受けると伸縮することができ、接続部材間に圧着させて、確実な導通を図ることができる。
また、この補強芯材を設けた部位が形状保持部位を構成するため、形状保持部位の部分では圧縮を受けても座屈させないことができる。 Since the conductive part covered by the base part constitutes an elastic connection part protruding from the part where the reinforcing core material is provided, the part of the conductive part covered by this base part can be expanded and contracted when compressed. It is possible to achieve reliable conduction by pressing between the members.
Moreover, since the site | part which provided this reinforcing core material comprises a shape maintenance site | part, even if it receives compression in the part of a shape maintenance site | part, it can prevent buckling.

硬質材を樹脂材とすることができる。硬質材を樹脂材としたため、金属板を用いる場合に比べて軽く、製造も容易である。また、導通部以外の絶縁性が確実になる。
また、ベース部で導通部と補強芯材との間隙を埋めることができる。ベース部が導通部と補強芯材との間隙を埋めていると、接続部材間に挟まれた際に補強芯材がある形状保持部位も収縮することができる。そのため、補強芯材があっても補強芯材が無い場合と同様に弾性コネクタが持つ柔軟性を維持することができる。 The hard material can be a resin material. Since the hard material is a resin material, it is lighter and easier to manufacture than using a metal plate. Moreover, insulation other than a conduction | electrical_connection part becomes reliable.
In addition, the gap between the conductive portion and the reinforcing core can be filled with the base portion. When the base portion fills the gap between the conductive portion and the reinforcing core material, the shape holding portion where the reinforcing core material is located can be contracted when sandwiched between the connecting members. Therefore, even if there is a reinforcing core material, the flexibility of the elastic connector can be maintained as in the case where there is no reinforcing core material.

絶縁性のゴム状弾性体でなるベース部と、導電方向に導電体が数珠繋ぎに配向する導通部と、ベース部を補強する金属材でなる補強芯材とを一体に備えており、接続部材間に挟持されて、これら接続部材どうしを相互に導通接続する柱状の弾性コネクタについて、補強芯材は金属塊からなり、導通部はその一端が補強芯材の頂部と連通しており、ベース部は補強芯材と導通部のそれぞれの外周面を被覆しており、導通部の他端と前記金属塊の底部が接続部材に接触可能であって、ベース部に被覆された導通部が補強芯材を設けた部分から突出する弾性接続部位と、補強芯材を有する形状保持部位とを構成することを特徴とする弾性コネクタを提供する。
補強芯材を金属塊で構成したため、補強強度の強い弾性コネクタを得ることができる。また、重心が安定して倒れにくく、ハンダ付けがし易い弾性コネクタである。 A base part made of an insulating rubber-like elastic body, a conduction part in which conductors are arranged in a daisy chain in the direction of conduction, and a reinforcing core made of a metal material that reinforces the base part are integrally provided between the connecting members. With respect to the columnar elastic connector that is sandwiched between and connected to each other, the reinforcing core is made of a metal lump, one end of the conductive portion is in communication with the top of the reinforcing core, and the base is The outer peripheral surfaces of the reinforcing core member and the conductive portion are covered, the other end of the conductive portion and the bottom of the metal block can contact the connecting member, and the conductive portion covered by the base portion is the reinforcing core member. An elastic connector is provided, which comprises an elastic connection portion projecting from a portion provided with a shape retaining portion and a shape maintaining portion having a reinforcing core member.
Since the reinforcing core member is made of a metal lump, an elastic connector having a strong reinforcing strength can be obtained. In addition, it is an elastic connector that has a stable center of gravity and is easy to be soldered.

そして、絶縁性のゴム状弾性体でなるベース部と、導電方向に導電体が数珠繋ぎに配向する導通部と、ベース部を補強する硬質材でなる補強芯材とを一体に備えており、接続部材間に挟持されて、これら接続部材どうしを相互に導通接続する柱状の弾性コネクタについて、ベース部に被覆された補強芯材を有する形状保持部位と、補強芯材を設けないベース部に被覆された導通部を有する弾性接続部位とが導電方向に積層して構成されることを特徴とする弾性コネクタを提供する。   A base part made of an insulating rubber-like elastic body, a conduction part in which the conductors are arranged in a daisy chain in the direction of conduction, and a reinforcing core made of a hard material that reinforces the base part are provided integrally. A columnar elastic connector that is sandwiched between members and electrically connects these connecting members to each other, is covered by a shape holding portion having a reinforcing core material covered by a base portion and a base portion not provided with a reinforcing core material. An elastic connector is provided in which an elastic connection portion having a conductive portion is laminated in a conductive direction.

ベース部に被覆された補強芯材を有する形状保持部位と、補強芯材を設けないベース部に被覆された導通部を有する弾性接続部位とが導電方向に積層して構成されるため、弾性接続部位で適度に圧縮を受けて伸縮し確実な導通を図ることができるとともに、形状保持部位で形状を保ち、弾性コネクタ自体の座屈を防止することができる。   Elastic connection because the shape-retaining part having the reinforcing core material covered by the base part and the elastic connecting part having the conductive part covered by the base part not provided with the reinforcing core material are laminated in the conductive direction. The portion can be appropriately compressed at the portion to expand and contract to ensure reliable conduction, and the shape can be maintained at the shape holding portion to prevent buckling of the elastic connector itself.

弾性接続部位の高さが、弾性コネクタの高さに対して５％〜５０％とすることができる。弾性接続部位の高さを、弾性接続部位と形状保持部位の両方の高さを加えた弾性コネクタの高さに対して５％〜５０％としたため、接続対象部材間の離間程度にかかわらず適度な圧縮が可能な弾性コネクタとすることができ、座屈を起こさずに確実な導通接触を図れる弾性コネクタである。   The height of the elastic connection portion can be 5% to 50% with respect to the height of the elastic connector. Since the height of the elastic connection part is 5% to 50% with respect to the height of the elastic connector including the height of both the elastic connection part and the shape holding part, it is appropriate regardless of the degree of separation between the connection target members. It is an elastic connector that can be made an elastic connector capable of proper compression and that can achieve reliable conduction contact without causing buckling.

底面の外径に対し高さが２倍以上の長さを有する弾性コネクタとすることができる。
底面の外径に対し高さが２倍以上の長さを有するため、幅狭な実装空間にあって、接続対象部材間が離れていても座屈させずに確実な導通を行うことができる。 It can be set as the elastic connector which has a length 2 times or more with respect to the outer diameter of a bottom face.
Since the height is more than twice as long as the outer diameter of the bottom surface, in a narrow mounting space, even if the members to be connected are separated, reliable conduction can be performed without buckling. .

弾性接続部位の高さは、０．５ｍｍ〜５．０ｍｍとすることができる。
弾性接続部位の高さを、０．５ｍｍ〜５．０ｍｍとしたため、接続対象部材間の間隙に応じて最良の弾性接続部位の長さを選択することができ、確実な導通接合を行わしめることができる。 The height of the elastic connection part can be 0.5 mm to 5.0 mm.
Since the height of the elastic connecting portion is set to 0.5 mm to 5.0 mm, the best length of the elastic connecting portion can be selected according to the gap between the connection target members, and reliable conductive joining is performed. Can do.

In this case, examples of the material of the conductor include good-electricity metals, resins, ceramics, and carbon black.

ベース部１２は、絶縁性のゴム状弾性体でなり、導通部１３や補強芯材１４を被覆して、導通部１３と補強芯材１４とを一体化させているほか、導電接点となる導通部１３や補強芯材１４の露出部分以外の部分を外部と絶縁している。
このベース部１２の材質には、絶縁性でゴム弾性を有する熱硬化性ゴム、熱可塑性エラストマーが使用できる。例えば、天然ゴム、シリコーンゴム、イソプレンゴム、ブタジエンゴム、アクリロニトリルブタジエンゴム、１，２−ポリブタジエン、スチレン−ブタジエンゴム、クロロプレンゴム、ニトリルゴム、ブチルゴム、エチレン−プロピレンゴム、クロロスリホンゴム、ポリエチレンゴム、アクリルゴム、エピクロルヒドリンゴム、フッ素ゴム、ウレタンゴム、スチレン系熱可塑性エラストマー、オレフィン系熱可塑性エラストマー、エステル系熱可塑性エラストマー、ウレタン系熱可塑性エラストマー、アミド系熱可塑性エラストマー、塩化ビニル系熱可塑性エラストマー、フッ化系熱可塑性エラストマー、イオン架橋系熱可塑性エラストマーなどが挙げられる。後述するように金型中で加熱硬化する場合は熱硬化性ゴムが好ましく、なかでも耐熱性の高いシリコーンゴム、フッ素ゴムがより好ましい。 The base portion 12 is made of an insulating rubber-like elastic body, covers the conducting portion 13 and the reinforcing core member 14, integrates the conducting portion 13 and the reinforcing core member 14, and conducts as a conductive contact. Portions other than the exposed portions of the portion 13 and the reinforcing core member 14 are insulated from the outside.
As the material of the base portion 12, thermosetting rubber or thermoplastic elastomer having insulating properties and rubber elasticity can be used. For example, natural rubber, silicone rubber, isoprene rubber, butadiene rubber, acrylonitrile butadiene rubber, 1,2-polybutadiene, styrene-butadiene rubber, chloroprene rubber, nitrile rubber, butyl rubber, ethylene-propylene rubber, chlorosulfone rubber, polyethylene rubber, Acrylic rubber, epichlorohydrin rubber, fluoro rubber, urethane rubber, styrene thermoplastic elastomer, olefin thermoplastic elastomer, ester thermoplastic elastomer, urethane thermoplastic elastomer, amide thermoplastic elastomer, vinyl chloride thermoplastic elastomer, fluorine A thermoplastic thermoplastic elastomer, an ion-crosslinked thermoplastic elastomer, and the like. As will be described later, when heat-curing in a mold, thermosetting rubber is preferable, and silicone rubber and fluorine rubber having high heat resistance are more preferable.

補強芯材１４は、弾性コネクタ１１に強度をもたらし形状保持部位１７を形成する主な構成要素となる。本実施形態では、銅板、鉄板等の金属板をハット形状に形成している。そして、頂部１４ｂは導通部１３の一端１３ａと接している。また、鍔部１４ａが弾性コネクタ１１の端部に露出し、回路基板上にハンダ付け可能となっている。ハット形状の内部は、中空になっており、弾性コネクタ１１自体の荷重を軽くしている。また、導通部１３の製造には金型に設けた磁性ピンによる磁場配向を利用するが、ハット形状の内部に磁性ピンを挿入することができるので、磁性導電粒子の配列がより確実な導通部１３を製造することができる。   The reinforcing core member 14 is a main component that gives strength to the elastic connector 11 and forms the shape holding portion 17. In the present embodiment, a metal plate such as a copper plate or an iron plate is formed in a hat shape. The top portion 14 b is in contact with the one end 13 a of the conducting portion 13. Further, the flange portion 14a is exposed at the end of the elastic connector 11, and can be soldered on the circuit board. The inside of the hat shape is hollow, reducing the load on the elastic connector 11 itself. In addition, although the magnetic field orientation by the magnetic pins provided in the mold is used for manufacturing the conduction part 13, the magnetic pins can be inserted into the inside of the hat shape. 13 can be manufactured.

こうした弾性コネクタ１１は、導通部１３と補強芯材１４の境界を基準にして、弾性接続部位１６と形状保持部位１７とに分けることができ、図面上方の導通部１３側が、補強芯材１４を設けた部分から突出する弾性接続部位１６を構成し、図面下方の補強芯材１４側が形状保持部位１７を構成している。   Such an elastic connector 11 can be divided into an elastic connection portion 16 and a shape holding portion 17 with reference to the boundary between the conducting portion 13 and the reinforcing core member 14. The elastic connection part 16 which protrudes from the provided part is comprised, and the reinforcement core material 14 side below a figure comprises the shape maintenance part 17. FIG.

弾性接続部位１６の高さは、弾性接続部位１６と形状保持部位１７の両方の高さを加えた弾性コネクタ１１の高さに対して５％〜５０％とすることができる。５％より低いと接続対象部材間にこの弾性コネクタを保持する際に弾性接続部位１６の収縮が十分ではなく、導通不良を起こす可能性がある。また、５０％を超えると、弾性接続部位１６が座屈してしまい、形状保持部位１７を設ける意味が薄れることになる。   The height of the elastic connecting portion 16 can be 5% to 50% with respect to the height of the elastic connector 11 including the height of both the elastic connecting portion 16 and the shape holding portion 17. If it is lower than 5%, when the elastic connector is held between the members to be connected, the elastic connecting portion 16 is not sufficiently contracted, which may cause poor conduction. Moreover, if it exceeds 50%, the elastic connection part 16 will buckle and the meaning which provides the shape maintenance part 17 will fade.

弾性コネクタ１１の形状は柱状であるが、柱形の底面の外径に対し、柱形の高さを２倍以上の長さとすることができる。形状保持部位１７が無い従来の弾性コネクタであれば外径に対する高さを２倍以上の長さとすると、座屈をするおそれが生じるのに対し、形状保持部位１７を設けていることで座屈の心配が無いからである。
また、弾性接続部位の高さは０．５ｍｍ〜５．０ｍｍとすることができる。０．５ｍｍより低いと補強芯材１４の成形が困難になり、５．０ｍｍを超えると実装した際の安定感が失われるからである。 The shape of the elastic connector 11 is a columnar shape, but the height of the columnar shape can be made twice or more the outer diameter of the bottom surface of the columnar shape. In the case of a conventional elastic connector having no shape holding portion 17, if the height with respect to the outer diameter is set to be twice or more, there is a risk of buckling. Because there is no worry.
Moreover, the height of the elastic connection part can be set to 0.5 mm to 5.0 mm. If the thickness is less than 0.5 mm, it is difficult to form the reinforcing core material 14, and if it exceeds 5.0 mm, the sense of stability when mounted is lost.

弾性コネクタ１１の製造の一例を説明する。
磁性導電体を分散した液状ゴムを金型のキャビティー内に注入し、このキャビティー内に磁力を印加して分散している磁性導電体をキャビティー内の一部に集めて配向させる。その後、液状ゴムを硬化して導通部１３と導通部１３の外周面１３ｃを被覆するベース部１２とを得る。一方で、平板状の金属板をハット形状に成形して補強芯材１４を得る。そして、導通部１３を備えるベース部１２にこの補強芯材１４をはめ込んで一体化し、略円柱状の弾性コネクタ１１を得る。 An example of manufacturing the elastic connector 11 will be described.
Liquid rubber in which a magnetic conductor is dispersed is injected into a cavity of a mold, and a magnetic force is applied to the cavity to collect and align the dispersed magnetic conductor in a part of the cavity. Thereafter, the liquid rubber is cured to obtain the conductive portion 13 and the base portion 12 that covers the outer peripheral surface 13 c of the conductive portion 13. On the other hand, a reinforcing metal member 14 is obtained by forming a flat metal plate into a hat shape. Then, the reinforcing core member 14 is fitted into and integrated with the base portion 12 including the conducting portion 13 to obtain the substantially cylindrical elastic connector 11.

第２実施形態〔図２〕：
第２実施形態の弾性コネクタ２１を図２の断面図で示す。この弾性コネクタ２１は、補強芯材２４が円筒状の樹脂板でなることや、導通部２３が補強芯材２４の円筒内にも及ぶこと、それに底面２１ａに金属箔層２５を備えること等が第１実施形態の弾性コネクタ１１と異なるが、ベース部２２と導通部２３、補強芯材２４が一体に形成されている点は第１実施形態の弾性コネクタ１１と同じである。 Second Embodiment [FIG. 2] :
The elastic connector 21 of 2nd Embodiment is shown with sectional drawing of FIG. In the elastic connector 21, the reinforcing core member 24 is made of a cylindrical resin plate, the conductive portion 23 extends into the cylinder of the reinforcing core member 24, and the metal foil layer 25 is provided on the bottom surface 21a. Although it differs from the elastic connector 11 of 1st Embodiment, the point by which the base part 22, the conduction | electrical_connection part 23, and the reinforcement core material 24 are integrally formed is the same as the elastic connector 11 of 1st Embodiment.

本実施形態では、補強芯材２４は円筒状の樹脂板からなる。導通部２３は、補強芯材２４の円筒内を貫通し、その一端２３ａは金属箔層２５と連通し、他端２３ｂは弾性コネクタ２１の表面に露出している。ベース部２２は導通部２３の外周面２３ｃを被覆し、また、補強芯材２４の内周面２４ｄと外周面２４ｃの両面を被覆している。そして、補強芯材２４を設けた一端２１ａ側に金属箔層２５を有している。この金属箔層２５は、導通部２３の一端２３ａに接触するだけでなく、補強芯材２４の底面も覆う広面積に形成されている。そして、導通部２３の他端２３ｂと金属箔層２５が接続部材（図示せず）に接触可能となっている。
こうした弾性コネクタ２１は、補強芯材２４の頂部２４ｂを基準にして、図面上方が補強芯材２４を設けた部分から導通部２３が突出する弾性接続部位２６を構成しており、また、図面下方の補強芯材２４を設けた部分が形状保持部位２７を構成している。 In the present embodiment, the reinforcing core member 24 is made of a cylindrical resin plate. The conducting portion 23 penetrates through the cylinder of the reinforcing core member 24, one end 23 a communicates with the metal foil layer 25, and the other end 23 b is exposed on the surface of the elastic connector 21. The base portion 22 covers the outer peripheral surface 23c of the conducting portion 23, and covers both the inner peripheral surface 24d and the outer peripheral surface 24c of the reinforcing core member 24. And it has the metal foil layer 25 in the one end 21a side which provided the reinforcement core material 24. FIG. The metal foil layer 25 is formed in a wide area that not only contacts the one end 23 a of the conducting portion 23 but also covers the bottom surface of the reinforcing core member 24. And the other end 23b of the conduction | electrical_connection part 23 and the metal foil layer 25 can contact a connection member (not shown).
In the elastic connector 21, the upper part of the drawing constitutes an elastic connection part 26 from which the conductive part 23 protrudes from the part where the reinforcing core member 24 is provided, and the lower part of the drawing is based on the top 24 b of the reinforcing core member 24. The portion provided with the reinforcing core member 24 constitutes the shape maintaining portion 27.

弾性接続部位２６の高さや全体に対する割合、弾性コネクタ２１の高さ等も第１実施形態の弾性コネクタ１１と同様にすることができる。   The height and ratio of the elastic connection portion 26 to the whole, the height of the elastic connector 21 and the like can be the same as those of the elastic connector 11 of the first embodiment.

弾性コネクタ２１の製造の一例を説明する。
樹脂を円筒状に成形し金型にインサートする。そして、磁性導電体を分散した液状ゴムをこの金型のキャビティー内に注入する。磁力を印加して分散している磁性導電体を集めて磁場配向させた後、液状ゴムを硬化させると、導通部２３の外周面２３ｃを被覆し、補強芯材２４の内周面２４ｄおよび外周面２４ｃを被覆して、導通部２３、補強芯材２４と一体となったベース部２２を得る。最後に補強芯材２４の底面に金属箔層２５を固着することで導通部２３と金属箔層２５が接触した略円柱状の弾性コネクタ２１を得る。 An example of manufacturing the elastic connector 21 will be described.
Mold the resin into a cylindrical shape and insert it into the mold. Then, liquid rubber in which the magnetic conductor is dispersed is injected into the cavity of this mold. After collecting magnetic conductors dispersed by applying a magnetic force and orienting the magnetic field, the liquid rubber is cured to cover the outer peripheral surface 23c of the conductive portion 23, and the inner peripheral surface 24d and outer periphery of the reinforcing core member 24. Covering the surface 24 c, the base portion 22 integrated with the conducting portion 23 and the reinforcing core member 24 is obtained. Finally, by fixing the metal foil layer 25 to the bottom surface of the reinforcing core member 24, the substantially cylindrical elastic connector 21 in which the conductive portion 23 and the metal foil layer 25 are in contact is obtained.

弾性コネクタ２１は、弾性コネクタ１１と比較すると、導通部２３とその導通部２３を被覆するベース部２２が形状保持部位２７をも貫いている点で相違する。そのため、接続部材間で弾性コネクタ２１が圧着させる場合に、その押圧力を受けて形状保持部位２７も収縮することができる。そのため、弾性接続部位２６や従来の補強芯材を有しない弾性コネクタが持つ柔軟性を維持することができる。
なお、本実施形態では補強芯材として樹脂板を用いているが金属板を用いることも可能である。 The elastic connector 21 is different from the elastic connector 11 in that the conductive portion 23 and the base portion 22 covering the conductive portion 23 also penetrate the shape holding portion 27. Therefore, when the elastic connector 21 is pressure-bonded between the connecting members, the shape holding portion 27 can be contracted by receiving the pressing force. Therefore, the softness | flexibility which the elastic connector which does not have the elastic connection part 26 and the conventional reinforcement core material has can be maintained.
In this embodiment, a resin plate is used as the reinforcing core material, but a metal plate can also be used.

変形例１〔図３〕：
第１実施形態の変形例として、補強芯材として用いた金属板１４に代えて金属塊３４を用いることができる。この金属塊３４を用いた弾性コネクタ３１を図３の断面図で示す。弾性コネクタ３１では、第１実施形態の弾性コネクタ１１と同様に補強芯材である金属塊３４のの外周面３４ｃをベース部３２で被覆しているが、弾性コネクタ１１と異なり、金属塊３４の外周面３４ｃの一部は被覆されずに外部に露出している。
また、金属塊３４の頂部３４ｂが導通部１３に連通する一方で、金属塊３４の底部３４ｅが接続部材に接触可能となっている。 Modification 1 (FIG. 3) :
As a modification of the first embodiment, a metal lump 34 can be used instead of the metal plate 14 used as the reinforcing core material. An elastic connector 31 using this metal lump 34 is shown in the sectional view of FIG. In the elastic connector 31, the outer peripheral surface 34 c of the metal mass 34, which is a reinforcing core material, is covered with the base portion 32 in the same manner as the elastic connector 11 of the first embodiment. A part of the outer peripheral surface 34c is exposed to the outside without being covered.
Moreover, while the top part 34b of the metal lump 34 is connected to the conduction | electrical_connection part 13, the bottom part 34e of the metal lump 34 can contact a connection member.

この弾性コネクタ３１の製造は、第１実施形態の弾性コネクタ１１と同様に行うことができるが、導通部１３の製造に際し、磁性ピンを金属塊３４の外側に置かざるを得ないので、金属塊３４自体が磁化されて磁性ピンの代わりとなる必要がある。
弾性コネクタ３１によれば、金属塊３４を用いているため、金属板１４を用いた弾性コネクタ１１に比較して強固であり、また、底部３４ｅの面積が広くなるためハンダ付けが容易になる。さらに、重心が安定し取扱いが容易である。しかしながら、金属部分の容積が増えるためコストが上がり、また、重くなるといった不都合がある。 The elastic connector 31 can be manufactured in the same manner as the elastic connector 11 of the first embodiment. However, since the magnetic pin must be placed outside the metal block 34 when the conductive portion 13 is manufactured, the metal block 34 itself needs to be magnetized to replace the magnetic pin.
According to the elastic connector 31, since the metal lump 34 is used, it is stronger than the elastic connector 11 using the metal plate 14, and soldering is easy because the area of the bottom 34 e is wide. Furthermore, the center of gravity is stable and easy to handle. However, since the volume of the metal portion increases, there is a disadvantage that the cost increases and becomes heavy.

変形例２〔図４〕：
第２実施形態の変形例として、補強芯材２４として用いた円筒状の樹脂板と導通部２３との間に隙間を設けずに両者が接触するように構成することができる。こうした弾性コネクタ４１を図４の断面図で示す。
また、この弾性コネクタ４１では、補強芯材２４の外周面２４ｃの一部はベース部４２に被覆されずに外部に露出している点で異なる。
弾性コネクタ４１の製造も弾性コネクタ２１と同様に行うことができる。 Modification 2 (FIG. 4) :
As a modified example of the second embodiment, the cylindrical resin plate used as the reinforcing core member 24 and the conductive portion 23 can be configured so as to contact each other without providing a gap. Such an elastic connector 41 is shown in the cross-sectional view of FIG.
Further, the elastic connector 41 is different in that a part of the outer peripheral surface 24 c of the reinforcing core member 24 is exposed to the outside without being covered with the base portion 42.
The elastic connector 41 can be manufactured in the same manner as the elastic connector 21.

弾性コネクタ４１によれば、補強芯材２４と導通部２３との間を隙間なく構成することができるため、補強芯材２４の内径を小さくすることができ、これにより弾性コネクタ４１全体を小さくすることができる。また、弾性コネクタ４１全体を小さくしても弾性コネクタ２１よりも補強芯材２４と金属箔層２５との固着面積を広く取ることができるので金属箔層２５を剥がれ難くすることができる。
また、補強芯材２４の外周面２４ｃの一部を外表面に露出させ、その露出させた部分を金属箔層２５との接触箇所である補強芯材２４の底部２４ｅとしたため、金属箔層２５の端部を補強芯材２４と固着することができるので、金属箔層２５の端部が折れ曲がり難い。 According to the elastic connector 41, since the reinforcing core member 24 and the conducting portion 23 can be configured without a gap, the inner diameter of the reinforcing core member 24 can be reduced, thereby reducing the entire elastic connector 41. be able to. Further, even if the entire elastic connector 41 is made smaller, the fixing area between the reinforcing core member 24 and the metal foil layer 25 can be made larger than that of the elastic connector 21, so that the metal foil layer 25 can be made difficult to peel off.
In addition, a part of the outer peripheral surface 24 c of the reinforcing core member 24 is exposed to the outer surface, and the exposed portion is used as the bottom 24 e of the reinforcing core member 24 that is a contact portion with the metal foil layer 25. Since the end portion of the metal foil layer 25 can be fixed to the reinforcing core member 24, the end portion of the metal foil layer 25 is not easily bent.
