Description

本発明は、デジタルカメラやビデオカメラおよび携帯電話などの小型電子機器に搭載されて、バッテリーパック（電池パック）のような接続用電極を備えた相手側電気機器との接続に用いられるコネクタに関するものである。   The present invention relates to a connector that is mounted on a small electronic device such as a digital camera, a video camera, and a mobile phone, and is used for connection to a counterpart electric device having a connection electrode such as a battery pack (battery pack). It is.

従来、この種のコネクタは、そのコンタクトが、ハウジングに保持される保持部と、プリント配線基板に半田付けなどで接続される接続部と、バッテリーパックの電極部と接触する接触部と、保持部と接触部の間を連結する弾性変位可能な略Ｓ字状の弾性変形部とを具備しており、バッテリーパックをコンタクトに押し付け、電極部を接触部に弾性接触させることにより、電気的接続をはたす構造のものが知られている。   Conventionally, in this type of connector, a contact is held by a housing, a connecting part connected to a printed wiring board by soldering, a contact part that contacts an electrode part of a battery pack, and a holding part And an elastically displaceable substantially S-shaped elastic deformable portion that connects between the contact portion and the contact portion, and the battery pack is pressed against the contact, and the electrode portion is brought into elastic contact with the contact portion, thereby making electrical connection. One with a structure is known.

そして、略横長直方体状ハウジングには、コンタクト収容室が長手方向（バッテリーパックの幅方向）に沿って所定ピッチで形成されており、コンタクトは、接触部が対応するコンタクト収容室の前面側開口部から前方向へ突出するとともに、弾性バネ機能を果たす弾性変形部の伸長方向を上下方向とし（底面に対して略垂直面内で折り返して形成し）、接続部が対応するコンタクト収容室の底面側（プリント配線基板面側）から下方向へ突出するよう収容室内に挿入されている。（例えば特許文献１参照）。   In the substantially horizontally long rectangular parallelepiped housing, contact housing chambers are formed at a predetermined pitch along the longitudinal direction (battery pack width direction), and the contacts are openings on the front side of the contact housing chamber to which the contact portions correspond. The front side of the contact accommodating chamber to which the connecting portion corresponds is formed with the extending direction of the elastically deforming portion serving as an elastic spring functioning in the up-and-down direction (folded in a substantially vertical plane with respect to the bottom surface). It is inserted into the accommodating chamber so as to protrude downward from the printed wiring board surface side. (For example, refer to Patent Document 1).

この公知例によれば、弾性変形部の変位を規制することにより、弾性変形部の湾曲部の変位量を制限でき、このため、弾性変形部の下方湾曲部（第２湾曲部）とハウジングの端面（例えばプリント配線基板面）の間隔を小さくすることができ、小型化が可能とされている。
特開２００５−１２９３７４号公報 According to this known example, the displacement amount of the bending portion of the elastic deformation portion can be limited by restricting the displacement of the elastic deformation portion. For this reason, the downward bending portion (second bending portion) of the elastic deformation portion and the housing The distance between the end faces (for example, the printed wiring board surface) can be reduced, and the size can be reduced.
JP 2005-129374 A

薄型化が進む小型電子機器においては、バッテリーパックとその接続用コネクタとの接続構造においても、さらに薄型化（例えば、小型チップ部品と同様にプリント配線基板上の実装高さが１．５ｍｍ以下）および小型化が図れる形態であることが望ましい。   In small electronic devices that are becoming thinner, the connection structure between the battery pack and its connector is further reduced (for example, the mounting height on the printed wiring board is 1.5 mm or less as in the case of small chip components). And it is desirable that the size can be reduced.

公知例のごとくの従来例において、その弾性変形部は、（バッテリーパックの押し付けによる）前面側からの押圧力を受けて撓む弾性変形部の弾性変位量（永久変形を起こさない撓み範囲量）を確保するため、薄板状にて有効バネ長（バネ機能としての有効長）を長くした（略Ｓ字状に蛇行させた）形態としている。   In the conventional example as in the known example, the elastic deformation portion is an elastic displacement amount of the elastic deformation portion that is deflected by a pressing force from the front side (by pressing the battery pack) (a deflection range amount that does not cause permanent deformation). In order to ensure the above, a thin plate shape is used in which the effective spring length (effective length as a spring function) is increased (meandered in a substantially S-shape).

しかし、このように、ハウジングの底面に対して略垂直方向となる上下方向に連結部を伸長させて、弾性変形部のバネ機能を高めている（弾性変形部の変位軌道はハウジングの底面と直交する）従来例のコネクタは、（ハウジングの底面からの）高さ方向に弾性変形部の収容スペースを確保する必要があるものであり、この高さ方向のスペースが制限されると、弾性変形部のバネ特性（材質、弾性変形部の有効バネ長や断面形状などから決まる弾性変位量と反発力の関係）の設定も制限され、有効バネ長の確保が困難となる。   However, in this way, the connecting portion is extended in the vertical direction that is substantially perpendicular to the bottom surface of the housing to enhance the spring function of the elastic deformation portion (the displacement track of the elastic deformation portion is orthogonal to the bottom surface of the housing). In the conventional connector, it is necessary to secure an accommodation space for the elastic deformation portion in the height direction (from the bottom surface of the housing). When the space in the height direction is limited, the elastic deformation portion The setting of the spring characteristics (the relationship between the elastic displacement and the repulsive force determined from the material, the effective spring length of the elastically deforming portion, the cross-sectional shape, etc.) and the repulsive force are also limited, and it is difficult to ensure the effective spring length.

言い換えると、薄型化を図るため、収容スペースの高さを低減させ、これに応じて弾性変形部を短小化させた場合、弾性変形部の永久（塑性）変形や接触圧の低下による接続性能の悪化が起こり得る。したがって、小型電子機器において（嵌め合い寸法の誤差を吸収させるため弾性変位量を大きく確保する必要がある）バッテリーパック着脱接続などの用途で使用されるこの種のコネクタでは、そのハウジングの高さが３ｍｍ以下となる薄型形態のものの実用は少ない。   In other words, in order to reduce the thickness, the height of the accommodation space is reduced, and when the elastic deformation portion is shortened accordingly, the connection performance due to permanent (plastic) deformation of the elastic deformation portion or a decrease in contact pressure is reduced. Deterioration can occur. Therefore, in this type of connector used in applications such as a battery pack attachment / detachment connection in a small electronic device (a large amount of elastic displacement must be secured to absorb the fitting dimension error), the height of the housing is low. There are few practical use of the thin form which becomes 3 mm or less.

よって、本発明の目的とするところは、上述のごとき従来技術の有する問題点を解決するものであって、接続性能を維持しつつ、さらなる薄型化が実現可能なコネクタを提供することにある。   Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide a connector capable of further reducing the thickness while maintaining connection performance.

上記目的を達成するために、請求項１に記載のコネクタは、コンタクトと、そのコンタクトに組み合わされる補助バネと、補助バネが組み合わされたコンタクトを収容保持するハウジングとを有し、コンタクトには前記収容保持された状態においてハウジングの前面側に突出する接触部とその接触部と相手側電気機器の電極部との接続に伴う相対的な押圧を受けて弾性変位する弾性変形部とが形成されており、その弾性変形部が前記弾性変位する際のその変位軌道はハウジングの前面と直交するハウジングの底面に沿った面内となるように設定されており、補助バネには前記収容され前記押圧を受けた状態において接触部を支持せしめる支持部と前記押圧を受けた状態においてコンタクトの弾性変形部とともに弾性変位する弾性変形部とが形成されている。   In order to achieve the above object, a connector according to claim 1 includes a contact, an auxiliary spring combined with the contact, and a housing that accommodates and holds the contact combined with the auxiliary spring. A contact portion that protrudes to the front side of the housing in the state of being housed and held, and an elastic deformation portion that is elastically displaced by receiving a relative pressure associated with the connection between the contact portion and the electrode portion of the counterpart electric device are formed. And the displacement trajectory when the elastically deforming portion is elastically displaced is set to be in a plane along the bottom surface of the housing perpendicular to the front surface of the housing. A support portion that supports the contact portion in the received state and an elastic deformation portion that elastically displaces together with the elastic deformation portion of the contact in the state where the pressure is received. It is.

このように、弾性変形部のその変位軌道（撓み方向）がハウジングの底面に沿う方向、すなわちハウジングの底面に対して（プリント配線基板に搭載される場合は、底面と対面するその基板上面に対しても）略平行になる方向で設定されている構成は、ハウジングの底面からの高さを低く設定する場合でも（弾性変形部の伸長方向がハウジングの高さ方向と異なるため）弾性変形部の有効バネ長の確保が容易である。   Thus, the displacement trajectory (bending direction) of the elastically deforming portion is in a direction along the bottom surface of the housing, that is, relative to the bottom surface of the housing (when mounted on a printed circuit board, with respect to the top surface of the substrate facing the bottom surface). Even if the configuration set in a substantially parallel direction is used, even when the height from the bottom surface of the housing is set low (because the extension direction of the elastic deformation portion is different from the height direction of the housing), the elastic deformation portion It is easy to ensure the effective spring length.

また、補助バネが接触部を支持しつつ（好適には、薄板状の導電性金属板から打ち抜き曲げ加工される）コンタクトの弾性変形部とともに弾性変位せしめる構成は、補助バネの弾性機能がコンタクトの弾性機能に加担できるため、ハウジングに収容されるコンタクトの弾性変形部の（収容状態において上下方向に渡る）材幅寸法を（高さの低いハウジングに収容させるため）狭くした場合においても、相手側電気機器の電極部との接触に必要とされる接触力の確保が容易となる。   In addition, the configuration in which the auxiliary spring supports the contact portion (preferably punched and bent from a thin plate-like conductive metal plate) and is elastically displaced together with the elastic deformation portion of the contact has the elastic function of the auxiliary spring. Because it can take part in the elastic function, even when the material width dimension of the elastic deformation part of the contact accommodated in the housing (vertically in the accommodated state) is narrowed (to accommodate in the housing with a low height), the other side It becomes easy to ensure the contact force required for contact with the electrode portion of the electric device.

請求項２によれば、コンタクトの弾性変形部には複数の湾曲部がコンタクトの収容保持状態においてハウジングの底面に沿った面内で蛇行状に順次連結して形成されており、補助バネの弾性変形部には前記組み合わされた状態において複数の湾曲部の少なくとも何れか一つの（好適には、補助バネの湾曲部の形成数がコンタクトの湾曲部と同数で、全ての）湾曲部に沿うように湾曲する湾曲部が形成されており、コンタクトの弾性変形部の（収容状態において左右横方向に渡る）横幅寸法が（湾曲部が単数の場合と比較して、有効バネ長を実質的に長くできるため）小幅であっても弾性変位量の確保が容易となるとともに、補助バネの湾曲部の収容スペースを（コンタクトの湾曲部の収容スペースとほぼ重ね合わせることが可能であるため）コンタクトの湾曲部の収容スペースとは別に大きく確保する必要がない。   According to the second aspect of the present invention, the elastic deformation portion of the contact is formed with a plurality of curved portions sequentially connected in a meandering manner in a plane along the bottom surface of the housing in a state where the contact is accommodated and held. In the combined state, the deforming portion is arranged along at least one of the plurality of bending portions (preferably, the number of forming the bending portions of the auxiliary spring is the same as the number of bending portions of the contact, and all the bending portions). The contact spring elastically deformed portion has a lateral width (in the horizontal direction in the accommodated state) that is substantially longer than that of a single curved portion. This makes it easy to secure the amount of elastic displacement even if the width is small, and the accommodation space of the curved portion of the auxiliary spring can be almost overlapped with the accommodation space of the curved portion of the contact. There is no need to separate large secured a space for accommodating the curved portion of Ntakuto.

このような弾性変形部が小幅であってもバネ機能に優れるコンタクトと収容スペースを大きく取らない補助バネとをハウジングに（その底面に沿うように）配列する構成とすれば、その配列ピッチの狭小化が可能となる。   Even if such an elastically deformable portion has a small width, a contact with an excellent spring function and an auxiliary spring that does not take up a large storage space are arranged on the housing (along its bottom surface), so that the arrangement pitch is small. Can be realized.

上述したように、本発明のコネクタは、接続性能を維持しつつ薄型化および小型化が実現可能なものである。   As described above, the connector of the present invention can be reduced in thickness and size while maintaining connection performance.

以下、添付図面の図１から図４に基づき本発明の実施の形態を説明する。図１は、本発明のコネクタの実施例を示した斜視図である。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4 of the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of the connector of the present invention.

図1に示すように、絶縁樹脂で成形されたハウジング３には、前面６側に開口する略角穴状の収容部４が底面５に沿う方向に並んで配置されおり、収容部４には、補助バネ３０が組み込まれたコンタクト１０が、前面６側に接触部１１を突出させる向きで収容されている。なお、本図において、コンタクト１０および補助バネ３０が収容される前の状態を説明するため、収容部４の内の１箇所においては、補助バネ３０およびコンタクト１０が未収容のままの状態を示している。   As shown in FIG. 1, a housing 3 formed of an insulating resin has a substantially square hole-shaped storage portion 4 that opens toward the front surface 6 side by side in a direction along the bottom surface 5. The contact 10 incorporating the auxiliary spring 30 is accommodated in the direction in which the contact portion 11 protrudes on the front surface 6 side. In addition, in this figure, in order to demonstrate the state before the contact 10 and the auxiliary | assistant spring 30 are accommodated, in one place of the accommodating part 4, the state in which the auxiliary | assistant spring 30 and the contact 10 are not accommodated is shown. ing.

ハウジング３に収容されるコンタクト１０は、薄板状の導電性金属板より打ち抜かれ曲げ加工されたものであり、収容状態において、収容部４に保持される保持部１３と、開口部７より突出する接触部１１とを備えている。そして、接触部１１と保持部１３との間には、湾曲部２１，２２，２３が蛇行状に順次連結された形態の弾性変形部２０が形成されており、保持部１３より延長する端末部１４には、プリント配線基板（図２に示す６０）に接続させるためのテール部２４，２５および半田付け固定させるための固定部２６が設けられている。   The contact 10 accommodated in the housing 3 is punched and bent from a thin plate-like conductive metal plate, and protrudes from the holding portion 13 held by the accommodating portion 4 and the opening 7 in the accommodated state. The contact part 11 is provided. An elastic deformation portion 20 is formed between the contact portion 11 and the holding portion 13 in such a manner that the curved portions 21, 22, and 23 are sequentially connected in a meandering manner, and extends from the holding portion 13. 14 is provided with tail portions 24 and 25 for connection to a printed wiring board (60 shown in FIG. 2) and a fixing portion 26 for fixing by soldering.

また、補助バネ３０は、薄板状の金属板より打ち抜かれ曲げ加工されたものであり、収容状態において収容部４に保持される保持部３３とコンタクト１０の接触部１１の内側に位置する支持部３１とを備えている。そして、支持部３１と保持部３３との間は、湾曲部４１，４２，４３が蛇行状に順次連結された形態の弾性変形部４０が形成されており、その形状は、コンタクト１０の湾曲部２１，２２，２３の湾曲形状にほぼ倣って湾曲した形状となっている。そして、補助バネ３０は、その湾曲部４１，４２，４３がコンタクト１０の湾曲部２１，２２，２３に沿うような状態でコンタクト１０に組み合わされて収容部４に挿入される（図３を参照）。そして、接触部１１が開口部７より所定の突出量となるまで挿入された収容状態において、コンタクト１０および補助バネ３０は、それらの保持部１３，３３に設けられた係止部１６，３６により収容部４内においてハウジング３に圧入固定（保持）されている。 The auxiliary spring 30 is stamped and bent from a thin plate-like metal plate, and is a support portion positioned inside the contact portion 11 of the holding portion 33 and the contact 10 held in the storage portion 4 in the storage state. 31. And between the support part 31 and the holding | maintenance part 33, the elastic deformation part 40 of the form to which the curved parts 41, 42, and 43 were sequentially connected in the meandering form is formed, The shape is the curved part of the contact 10. The curved shape substantially follows the curved shape of 21, 22, and 23. Then, the auxiliary spring 30 is inserted into the accommodating portion 4 by being combined with the contact 10 in a state where the curved portions 41, 42, 43 are along the curved portions 21, 22, 23 of the contact 10 (see FIG. 3). ). In the accommodated state in which the contact portion 11 is inserted until a predetermined amount of protrusion is obtained from the opening portion 7, the contact 10 and the auxiliary spring 30 are held by the locking portions 16 and 36 provided in the holding portions 13 and 33. The housing 4 is press-fitted and fixed (held) to the housing 3.

また、配列されたコンタクト１０の接触部１１におけるそれぞれの頂部１５の配列ピッチＰは、相手側電気機器であるバッテリーパック（図２および図４における５０）の電極部（同、５１）の配列ピッチに対応するように設定されている。   Further, the arrangement pitch P of the top portions 15 in the contact portions 11 of the arranged contacts 10 is the arrangement pitch of the electrode portions (51) of the battery pack (50 in FIGS. 2 and 4) which is the counterpart electric device. It is set to correspond to.

図２は、図１に示したコネクタ１とバッテリーパック５０との接続過程を示した側面図（部分断面図）であり、図２（ａ）は、接続前の状態を、図２（ｂ）は、接続完了時の状態を示している。プリント配線基板６０に搭載されたコネクタ１は、コンタクト１０の固定部２６がプリント配線基板６０上に（半田付けされて）固定され、さらにテール部２４，２５がプリント配線基板６０に設けられた配線パターン（図示せず）に（固定部２６とともに半田付けされて）接続されている。これにより、コンタクト６０が３点で基板６０に固定され、バッテリーパックの接続によりコンタクト１０作用する水平方向の外力に対して抗力を高めた構成になっている。   2 is a side view (partial cross-sectional view) showing a connection process between the connector 1 and the battery pack 50 shown in FIG. 1, and FIG. 2 (a) shows a state before connection, and FIG. Indicates the state when the connection is completed. In the connector 1 mounted on the printed wiring board 60, the fixing part 26 of the contact 10 is fixed (soldered) on the printed wiring board 60, and the tail parts 24 and 25 are provided on the printed wiring board 60. It is connected to a pattern (not shown) (soldered together with the fixing portion 26). Thereby, the contact 60 is fixed to the substrate 60 at three points, and the resistance is increased against the horizontal external force acting on the contact 10 by the connection of the battery pack.

電極部５１の配設側をコネクタ１の前面６側に向けた接続前の状態にあるバッテリーパック５０は、電極部５１の配設側を先頭にして、前面６より突出する接触部１１に向かい、接続完了となる所定の位置まで水平（図２における左から右へ向かう方向）に移動する。この過程で、バッテリーパック５０の電極部５１が接触部１１を押圧し、接触部１１がハウジング３の内部方向に押し込まれていく。   The battery pack 50 in a state before connection with the electrode portion 51 disposed side facing the front surface 6 side of the connector 1 is directed to the contact portion 11 protruding from the front surface 6 with the electrode portion 51 disposed side at the head. Then, it moves horizontally (in the direction from left to right in FIG. 2) to a predetermined position where the connection is completed. In this process, the electrode part 51 of the battery pack 50 presses the contact part 11, and the contact part 11 is pushed into the inside of the housing 3.

図３および図４は、図２に示した接続過程におけるコネクタ１の内部の動作状態を示しており、説明のためにハウジング３の上面側を取り除いた状態で上方視した部分平面図で示している。   3 and 4 show the internal operation state of the connector 1 in the connection process shown in FIG. 2, and are shown in a partial plan view viewed from above with the upper surface side of the housing 3 removed for the sake of explanation. Yes.

図３において、ハウジング３の開口部７より突出するコンタクト１０の接触部１１の内側には補助バネ３０の先端部分である支持部３１が位置しており、コンタクト１０の第１湾曲部２１および第３湾曲部２３の内側に補助バネ３０の第１湾曲部４１および第３湾曲部４３が、コンタクト１０の第２湾曲部２２の外側に補助バネ３０の第２湾曲部４２がそれぞれ（わずかに離間して倣うように）沿って位置付けられている。この状態において、コンタクト１０の弾性変形部２０に形成された湾曲部２１，２２，２３および補助バネ３０の弾性変形部４０に形成された湾曲部４１，４２，４３は、その湾曲度を深める方向に（蛇行状の弾性変形部２０，４０が縮まるように）弾性変位することが可能である。   In FIG. 3, a support portion 31, which is a tip portion of the auxiliary spring 30, is positioned inside the contact portion 11 of the contact 10 that protrudes from the opening 7 of the housing 3. The first bending portion 41 and the third bending portion 43 of the auxiliary spring 30 are located inside the third bending portion 23, and the second bending portion 42 of the auxiliary spring 30 is located slightly outside the second bending portion 22 of the contact 10 (slightly spaced apart). To be imitated). In this state, the bending portions 21, 22, 23 formed on the elastic deformation portion 20 of the contact 10 and the bending portions 41, 42, 43 formed on the elastic deformation portion 40 of the auxiliary spring 30 increase the degree of bending. (So that the meandering elastic deformation portions 20, 40 are contracted).

図４において、バッテリーパック５０の移動（押し込み）により弾性変形部２０は、補助バネ３０の弾性変形部４０とともにそれらが縮まる方向（図４における右方向）に弾性変位して（撓んで）おり、この弾性変位過程における弾性変形部２０の変位軌道（撓みの軌跡）は、ハウジング３の底面（図２における５）に沿って略水平となる向きとなっている。このように変位軌道が略水平に描かれるように設定された本実施例のコネクタ１は、ハウジング３の高さ寸法（図２におけるＡ寸法）が比較的に低い場合であっても、（弾性変形部の伸長方向（折り返し方向）をハウジングの高さ方向としていないため）バネ特性に大きく影響する弾性変形部２０の有効バネ長を大きく（長く）設定できる。   In FIG. 4, the elastic deformation portion 20 is elastically displaced (flexed) in the direction in which the elastic deformation portion 20 contracts together with the elastic deformation portion 40 of the auxiliary spring 30 (right direction in FIG. 4) by the movement (pushing) of the battery pack 50. The displacement trajectory (deflection trajectory) of the elastic deformation portion 20 in the elastic displacement process is oriented substantially horizontally along the bottom surface (5 in FIG. 2) of the housing 3. In this way, the connector 1 of the present embodiment set so that the displacement trajectory is drawn substantially horizontally, even if the height dimension of the housing 3 (dimension A in FIG. 2) is relatively low (elasticity The effective spring length of the elastic deformation portion 20 that greatly affects the spring characteristics can be set large (long) because the extension direction (folding direction) of the deformation portion is not the height direction of the housing.

また、接触部１１は、バッテリーパック５０の電極部５１により押圧されて開口部７方向に押し込まれており、電極部５１との当接部５２には、その押圧により弾性変位した弾性変形部２０の反発力により、接触力が作用しており、バッテリーパック５０とコネクタ１とは、電気的に接続が可能な状態となっている。そして、押し込まれた接触部１１を受けるように支持する補助バネ３０の支持部３１も接触部１１とともに開口部７方向に押し込まれており、弾性変位した弾性変形部４０の反発力により、支持部３１は、接触部１１を付勢し、当接部５２における接触力を増強させている。なお、接触部１１の頂部１５は、その内側が凹状となるようエンボス（絞り成形）加工がなされており、さらに、支持部３１の先端部分は、その外側が凸状となるようエンボス（絞り成形）加工がなされており、上述の押圧状態にあるとき、その凹凸が重なるように（支持部３１が接触部１１から外れないように）設定されている。   Further, the contact portion 11 is pressed by the electrode portion 51 of the battery pack 50 and is pushed in the direction of the opening 7, and the contact portion 52 with the electrode portion 51 is elastically displaced by the elastic deformation portion 20 due to the pressing. Due to the repulsive force, a contact force is applied, and the battery pack 50 and the connector 1 are in an electrically connectable state. The support portion 31 of the auxiliary spring 30 that supports the pressed contact portion 11 is also pushed in the direction of the opening 7 together with the contact portion 11, and the support portion is supported by the repulsive force of the elastically deformable elastic deformation portion 40. 31 urges the contact portion 11 to increase the contact force at the contact portion 52. The top portion 15 of the contact portion 11 is embossed (drawn) so that the inside is concave, and the tip of the support portion 31 is embossed (drawn) so that the outside is convex. It is set so that the unevenness overlaps when it is processed and is in the above-mentioned pressing state (so that the support portion 31 does not come off the contact portion 11).

このように、補助バネ３０の弾性機能がコンタクト１０の弾性機能に加担できる形態は、ハウジング３に収容されるコンタクト１０の弾性変形部２０および接触部１１の材幅寸法（図２におけるＢ寸法）を小さくした（反発力が低下する）場合においても、電極部５１との接触に必要とされる接触力（反発力）の確保が可能となり、（弾性変形部２０の材幅寸法が小さくなればコンタクト１０の小型化が可能となるため）ハウジング３の高さ（図２におけるＡ寸法）を低くさせることが可能となる。   Thus, the form in which the elastic function of the auxiliary spring 30 can participate in the elastic function of the contact 10 is the material width dimension of the elastic deformation part 20 of the contact 10 and the contact part 11 accommodated in the housing 3 (dimension B in FIG. 2). Even when (repulsive force is reduced), it is possible to secure a contact force (repulsive force) required for contact with the electrode portion 51 (if the material width dimension of the elastically deforming portion 20 is reduced). Since the contact 10 can be downsized, the height of the housing 3 (dimension A in FIG. 2) can be reduced.

また、湾曲部２１，２２，２３および湾曲部４１，４２，４３が蛇行状（略Ｓ字状）に順次連結され、湾曲部４１，４２，４３が湾曲部２１，２２，２３の湾曲形状に倣うように湾曲して沿う本実施例の形態は、その横幅方向の寸法（図３におけるＷ寸法）が比較的小さい場合でも弾性変形部２０，４０の有効バネ長を大きく（長く）設定できる。また、補助バネ３０を有する形態であっても、その収容スペースを（コンタクト１０の収容スペース内にほぼ収めることができるため）大きく確保する必要がないため、（変位軌道が略水平となるように設定されるコネクタであっても）ハウジング３に配列されるコンタクト１０の配列ピッチ（図１におけるＰ寸法）の狭小化が可能となる。   Further, the bending portions 21, 22, 23 and the bending portions 41, 42, 43 are sequentially connected in a meandering shape (substantially S-shaped), so that the bending portions 41, 42, 43 have the bending shapes of the bending portions 21, 22, 23. In the embodiment of the present embodiment that is curved so as to follow, the effective spring length of the elastically deformable portions 20 and 40 can be set large (long) even when the dimension in the width direction (W dimension in FIG. 3) is relatively small. Even if the auxiliary spring 30 is provided, it is not necessary to secure a large accommodation space (because it can be accommodated in the accommodation space of the contact 10), so that the displacement trajectory is substantially horizontal. The arrangement pitch (P dimension in FIG. 1) of the contacts 10 arranged in the housing 3 can be reduced (even if the connector is set).

なお、本実施例において、コンタクト１０および補助バネ３０は、それぞれ湾曲部が３箇所形成された形態としたが、これに限定されるものではなく、例えば、コンタクトは湾曲部の形成数をさらに増やして弾性変位量を増加させた形態でも良く、（高導電性を必要としない）補助バネは、（高反発力が得られ弾性変位量も大きく設定することが可能な）高剛性で薄板状の金属板（例えば、板厚０．１ｍｍ以下のステンレス鋼板）を素材として、湾曲部の形成数の少ない簡素構造の形態としても良い。   In the present embodiment, the contact 10 and the auxiliary spring 30 each have three curved portions. However, the present invention is not limited to this. For example, the contact further increases the number of curved portions formed. The auxiliary spring (which does not require high electrical conductivity) may have a configuration that increases the amount of elastic displacement, and the auxiliary spring (which can obtain a high repulsive force and can be set to a large amount of elastic displacement) has a high rigidity and a thin plate shape. A metal plate (for example, a stainless steel plate having a thickness of 0.1 mm or less) may be used as a raw material to have a simple structure with a small number of curved portions.
