Abstract

PROBLEM TO BE SOLVED: To provide a card connector surface mounted on a circuit board and into which a card, e.g., a memory card, is inserted, in which a switch for detecting insertion and withdrawal of a card is provided, and coplanarity is ensured while suppressing the cost.SOLUTION: A card connector includes a switch 23 consisting of a first contact member 23a and a second contact member 23b which detect insertion of a card by coming into contact with each other when a card is not inserted, and separating from each other when a card is inserted and pushes the first contact member 23a. The second contact member 23b is composed of the same member as one contact 22_3 out of a plurality of contacts 22_1-22_6, and connected with a circuit board via the substrate connection 22b_3 of the one contact 22_3.

Description

本発明は、回路基板に表面実装されてメモリカード等のカードが挿入されるカードコネクタに関する。   The present invention relates to a card connector that is surface-mounted on a circuit board and into which a card such as a memory card is inserted.

上記のタイプのカードコネクタは、ハウジングを形成する樹脂に、複数のコンタクトが繋がった形状の金属板がインサート成形され、成形後に金属板を切断して複数のコンタクトに分離するという工程を経て作製される（特許文献１参照）。   The card connector of the above type is manufactured through a process in which a metal plate having a shape in which a plurality of contacts are connected to a resin forming a housing is insert-molded, and the metal plate is cut and separated into a plurality of contacts after molding. (See Patent Document 1).

ここで、このタイプのカードコネクタは、ハウジングの厚みが薄いにもかかわらず、回路基板との接触面積が広いという形状を有する。この場合、コンタクトの基板接続部のいわゆる共平面性が問題となる。すなわち、インサート成形された金属板由来の複数のコンタクトの、回路基板に接続される基板接続部が、それら複数のコンタクトにわたって十分な精度で１つの平面上にあることが必要となる。複数のコンタクトのうちの１つでもその平面から外れると回路基板に表面実装した際に半田付け不良のおそれがある。近年、このタイプのカードコネクタは小型化、低背化が著しく進んできている。このためハウジングの厚みが益々薄くなり、成形金型の僅かな寸法誤差や成形時の僅かな反りや変形等が基板接続部の共平面性に大きく影響する。この共平面性を確保するため、複数のコンタクトの基板接続部は互いに近接した位置に配置するようにレイアウトが工夫される。   Here, this type of card connector has a shape in which the contact area with the circuit board is wide despite the thin housing. In this case, so-called coplanarity of the substrate connecting portion of the contact becomes a problem. That is, it is necessary that the board connecting portions of the plurality of contacts derived from the insert-molded metal plate to be connected to the circuit board are on one plane with sufficient accuracy over the plurality of contacts. If even one of the plurality of contacts deviates from the plane, there is a risk of poor soldering when surface-mounted on a circuit board. In recent years, this type of card connector has been remarkably reduced in size and height. For this reason, the thickness of the housing is further reduced, and a slight dimensional error of the molding die and a slight warp or deformation at the time of molding greatly affect the coplanarity of the board connecting portion. In order to ensure this coplanarity, the layout is devised so that the substrate connecting portions of the plurality of contacts are arranged at positions close to each other.

ここで、上記のタイプのカードコネクタには、カードの挿抜を検出するスイッチを組み込むことが多い。このスイッチは、カードが最終位置まで挿入されたことを検出するスイッチであるため、複数のコンタクトとは離れた、カードコネクタの奥側に配置される。このスイッチ基板接続部についてもコンタクトの基板接続部との共平面性を確保する必要がある。   Here, a switch for detecting insertion / removal of a card is often incorporated in the above type of card connector. Since this switch is a switch for detecting that the card has been inserted to the final position, it is disposed on the back side of the card connector, away from the plurality of contacts. It is necessary to ensure the coplanarity of the switch board connecting portion with the contact board connecting portion.

特許文献２には、スイッチを構成する２つの接点部材がハウジングに圧入された構造のスイッチが開示されている。圧入の場合、インサート成形よりも高い精度を確保することができる。したがって、そのスイッチを構成する接点部材の基板接続部がコンタクトの基板接続部から離れた位置にあっても、基板接続部の共平面性を確保することができる。   Patent Document 2 discloses a switch having a structure in which two contact members constituting the switch are press-fitted into a housing. In the case of press-fitting, it is possible to ensure higher accuracy than insert molding. Therefore, even if the board connecting portion of the contact member constituting the switch is located away from the board connecting portion of the contact, the coplanarity of the board connecting portion can be ensured.

特開２００６−２５２９５０号公報JP 2006-252950 A 米国特許第７，２５８，２７８号明細書US Pat. No. 7,258,278

接点部材を圧入するには、上記のインサート成形用の金属板とは別に接点部材を製造し圧入する必要があり、工数やコストの上昇を招く。スイッチとしての機能を確保する観点からは、スイッチ用の２つの接点部材のうちの１つをインサート用の金属板に配置し、別途に製造して圧入する接点部材の数を１つとすることができる。ただしこの場合、上記の金属板に配置したスイッチ用の接点部材は、コンタクトから離れた、カードコネクタの奥側に配置する必要があり、共平面性の問題が残る。   In order to press-fit the contact member, it is necessary to manufacture and press-fit the contact member separately from the above-described metal plate for insert molding, resulting in an increase in man-hours and costs. From the viewpoint of ensuring the function as a switch, one of the two contact members for the switch is arranged on the metal plate for the insert, and the number of contact members separately manufactured and press-fitted is one. it can. However, in this case, the switch contact member disposed on the metal plate needs to be disposed on the back side of the card connector away from the contact, and the coplanarity problem remains.

本発明は、上記事情に鑑み、カードの挿抜検出用のスイッチを備えるとともに、コストを抑えつつ基板接続部の共平面性を確保したカードコネクタを提供することを目的とする。   In view of the circumstances described above, an object of the present invention is to provide a card connector that includes a switch for detecting insertion / removal of a card, and that ensures coplanarity of a board connecting portion while suppressing cost.

上記目的を達成する本発明のカードコネクタは、
回路基板に表面実装されて、複数の接続パッドが形成されたカードが挿入されるカードコネクタであって、
ハウジングと、
表面実装用の基板接続部と、挿入されたカードの複数の接続パッドそれぞれに接触してカードと導通する接点部とを有する複数のコンタクトと、
カード無挿入時に互いに接触しカード挿入により第１の接点部材がカードに押されて互いに離間することでカードの挿入を検出する、その第１の接点部材と第２の接点部材とからなるスイッチとを備え、
上記第２の接点部材が、複数のコンタクトのうちの１つのコンタクトと同一の部材で構成され、その１つのコンタクトの基板接続部を介して回路基板に接続されるものであることを特徴とする。 The card connector of the present invention that achieves the above object is
A card connector into which a card that is surface-mounted on a circuit board and formed with a plurality of connection pads is inserted,
A housing;
A plurality of contacts having a substrate connection part for surface mounting and a contact part that contacts each of the plurality of connection pads of the inserted card and is electrically connected to the card;
A switch composed of a first contact member and a second contact member that contact each other when the card is not inserted and the first contact member is pushed by the card and separated from each other by the card insertion, and detects the insertion of the card; With
The second contact member is composed of the same member as one of the plurality of contacts, and is connected to the circuit board via a substrate connecting portion of the one contact. .

複数のコンタクトのうちの１つは、グラウンドに接続されるコンタクトであり、また、スイッチを構成する２つの接点部材のうちの一方はグラウンドに接続される。本発明のカードコネクタは、この点に着目したものである。すなわち、本発明のカードコネクタは、スイッチ用の一方の接点部材である第２の接点部材を、１つのコンタクトと同一の部材で構成しその１つのコンタクトの基板接続部を介して回路基板に接続する構造としている。このため、スイッチがコンタクトから離れた位置にあっても基板接続部の共平面性が確保される。   One of the plurality of contacts is a contact connected to the ground, and one of the two contact members constituting the switch is connected to the ground. The card connector of the present invention focuses on this point. That is, in the card connector of the present invention, the second contact member, which is one contact member for the switch, is composed of the same member as one contact, and is connected to the circuit board via the substrate connecting portion of the one contact. It has a structure to do. For this reason, even if the switch is located away from the contact, the coplanarity of the board connecting portion is ensured.

ここで、本発明のカードコネクタでは、典型的には、上記複数のコンタクトおよび上記第２の接点部材が、ハウジングを構成する樹脂にインサート成形された金属板からなり、上記第１の接点がハウジングに圧入された金属部材からなる。   Here, in the card connector of the present invention, typically, the plurality of contacts and the second contact member are made of a metal plate insert-molded in a resin constituting the housing, and the first contact is the housing. It consists of a metal member press-fitted into

第２の接点部材は、上記の通り１つのコンタクトと繋がっていてそのコンタクトの基板接続部を介して回路基板に接続されるため、インサート成形であっても基板接続部の共平面性が確保される。また、この第２の接点部材を別部品として製造して圧入する必要がないため、その分コストが抑えられる。スイッチを構成するもう一方の接点部材である第１の接点部材は、ハウジングに圧入された金属部材であり、高い精度が確保されるため、その第１の金属部材の基板接続部がコンタクトの基板接続部から離れた位置にあっても基板接続部の共平面性が確保される。   Since the second contact member is connected to one contact as described above and is connected to the circuit board through the substrate connecting portion of the contact, the coplanarity of the substrate connecting portion is ensured even in insert molding. The Further, since it is not necessary to manufacture and press-fit the second contact member as a separate part, the cost can be reduced accordingly. The first contact member, which is the other contact member constituting the switch, is a metal member press-fitted into the housing, and since high accuracy is ensured, the substrate connection portion of the first metal member is the contact substrate. Coplanarity of the board connecting portion is ensured even at a position away from the connecting portion.

以上の本発明のカードコネクタによれば、コストを抑えつつ基板接続部の共平面性が確保される。   According to the above card connector of the present invention, the coplanarity of the board connecting portion is ensured while the cost is suppressed.

以下本発明の実施の形態を説明する。   Embodiments of the present invention will be described below.

図１は、本発明の一実施形態としてのカードコネクタの斜視図である。   FIG. 1 is a perspective view of a card connector as an embodiment of the present invention.

また、図２，図３は、図１に外観を示すカードコネクタからシェルを外してハウジングの上面側を示した、それぞれ斜視図および平面図である。   2 and 3 are a perspective view and a plan view, respectively, showing the upper surface side of the housing with the shell removed from the card connector whose appearance is shown in FIG.

このカードコネクタ１０は、図１に示すように、ハウジング組立体２０とシェル３０とを有し、それらの間に、カード挿入口１１が設けられている。   As shown in FIG. 1, the card connector 10 includes a housing assembly 20 and a shell 30, and a card insertion slot 11 is provided between them.

ハウジング組立体２０は、図２，図３に示すように、ハウジング２１と、そのハウジング２１に対しインサート成形された複数のコンタクト２２＿１〜２２＿６と、２つの接点部材２３ａ，２３ｂからなるスイッチ２３を有する。このスイッチ２３を構成する２つの接点部材２３ａ，２３ｂは、カード（図示せず）が挿入されていない状態では互いに接触している。このスイッチ２３を構成する一方の接点部材２３ｂは、コンタクト２２＿１〜２２＿６とともにハウジング２１にインサート成形されたものである。これらのコンタクト２２＿１〜２２＿６や接点部材２３ｂをインサート成形するにあたっては、それらのコンタクト２２＿１〜２２＿６や接点部材２３ｂが繋がった形状の金属板が用意されてその金属板がインサート成形される。そして、成形後に金属板の必要な箇所が切断されて、コンタクト２２＿１〜２２＿６や接点部材２３ｂが形成される。   As shown in FIGS. 2 and 3, the housing assembly 20 includes a housing 21, a plurality of contacts 22_1 to 22_6 insert-molded to the housing 21, and a switch 23 including two contact members 23a and 23b. . The two contact members 23a and 23b constituting the switch 23 are in contact with each other when a card (not shown) is not inserted. One contact member 23b constituting the switch 23 is insert-molded in the housing 21 together with the contacts 22_1 to 22_6. In insert molding these contacts 22_1 to 22_6 and the contact member 23b, a metal plate having a shape connected to the contacts 22_1 to 22_6 and the contact member 23b is prepared, and the metal plate is insert-molded. And the required location of a metal plate is cut | disconnected after shaping | molding, and contacts 22_1-22_6 and the contact member 23b are formed.

それらのコンタクト２２＿１〜２２＿６は、図３に実線と点線で示すようにそれぞれ広がっている。各コンタクト２２＿１〜２２＿６は、挿し込まれたカード（図示せず）のハウジング２１側を向いた面に形成されている各接続パッドに接触する接点部２２ａ＿１〜２２ａ＿６と、回路基板（図示せず）に表面実装される基板接続部２２ｂ＿１〜２２ｂ＿６とを有する。それらのコンタクト２２＿１〜２２＿６の基板接続部２２ｂ＿１〜２２ｂ＿６は、互いに近接した位置に配置され、これにより共平面性の精度を確保している。   The contacts 22_1 to 22_6 are spread as shown by solid lines and dotted lines in FIG. Each contact 22_1 to 22_6 includes contact portions 22a_1 to 22a_6 that contact each connection pad formed on the surface of the inserted card (not shown) facing the housing 21 and a circuit board (not shown). Board-connecting portions 22b_1 to 22b_6 that are surface-mounted. The board connecting portions 22b_1 to 22b_6 of the contacts 22_1 to 22_6 are arranged at positions close to each other, thereby ensuring the accuracy of coplanarity.

また、スイッチ２３を構成するもう一方の接点部材２３ａは、カードに押されて弾性変形させる必要上、別体の金属部材で形成されていて、一端部２３１ａがハウジング２１に圧入されて片持ち梁形状となっている。   In addition, the other contact member 23a constituting the switch 23 is formed of a separate metal member so as to be elastically deformed by being pushed by the card, and the one end 231a is press-fitted into the housing 21 so as to be cantilevered. It has a shape.

また、このハウジング組立体２０にはさらに、スライダ２４、カムバー２５、およびコイルバネ２６が備えられている。スライダ２４は、ハウジング２１に対し、カードの挿入方向（矢印Ａ方向）および抜取方向（矢印Ｂ方向）にスライドする部材である。このスライダ２４は、コイルバネ２６により抜取方向（矢印Ｂ方向）に付勢されている。このスライダ２４は、挿入されてきたカードに押されるカード受け部２４１と、いわゆるハートカム溝２４２を有する。ハートカム溝２４２にはカムバー２５の先端部のカムピン２５１が入り込んでいる。   The housing assembly 20 further includes a slider 24, a cam bar 25, and a coil spring 26. The slider 24 is a member that slides relative to the housing 21 in the card insertion direction (arrow A direction) and the drawing direction (arrow B direction). The slider 24 is urged by a coil spring 26 in the extraction direction (arrow B direction). The slider 24 has a card receiving portion 241 to be pushed by the inserted card and a so-called heart cam groove 242. A cam pin 251 at the tip of the cam bar 25 is inserted into the heart cam groove 242.

カードが挿入されてくるとカード受け部２４１にカードが当接する。カードがさらに挿入されるとスライダ２４がカードに押され、そのスライダ２４が、コイルバネ２６の付勢に抗して挿入方向（矢印Ａ方向）にスライドする。このスライダ２４が挿入方向最終位置までスライドすると、カムピン２５１がハートカム溝２４２のロック位置２４２ａに入り込み、スライダ２４はその最終位置までスライドした状態のままロックされる。挿入されているカードを指で再度挿入方向に押すと、カムピン２５１がハートカム溝２４２のロック位置２４２ａから外れる。その後カードから指を離すと、スライダ２４がコイルバネ２６に押されて抜取方向（矢印Ｂ方向）にスライドする。これによりカードがスライダ２４に押されて、抜取方向に、カード挿入口１１（図１参照）から一部が食み出した状態となるまで移動する。このカードは指あるいはピンセットなどの道具で摘んで抜き取られる。   When the card is inserted, the card comes into contact with the card receiving portion 241. When the card is further inserted, the slider 24 is pushed by the card, and the slider 24 slides in the insertion direction (arrow A direction) against the bias of the coil spring 26. When the slider 24 slides to the final position in the insertion direction, the cam pin 251 enters the lock position 242a of the heart cam groove 242 and the slider 24 is locked while being slid to the final position. When the inserted card is pushed again in the insertion direction with a finger, the cam pin 251 is disengaged from the lock position 242a of the heart cam groove 242. Thereafter, when the finger is released from the card, the slider 24 is pushed by the coil spring 26 and slides in the extraction direction (arrow B direction). As a result, the card is pushed by the slider 24 and moves in the extraction direction until part of the card protrudes from the card insertion slot 11 (see FIG. 1). This card is removed by picking it with a tool such as a finger or tweezers.

また、カードが挿入されてきたとき、そのカードの挿入の最終に近い段階でスイッチ２３の一方の接点部材２３ａがカードで押されて弾性変形する。すると、この接点部材２３ａがもう一方の接点部材２３ｂから離れ、これによりカードが挿入されたことが検出される。挿入されたカードが上記にようにして抜取方向に移動すると、接点部材２３ａが再び接点部材２３ｂに接触し、これによりカードの抜取りが検出される。   When a card is inserted, one contact member 23a of the switch 23 is pushed by the card and elastically deforms at a stage near the end of the card insertion. Then, the contact member 23a is separated from the other contact member 23b, thereby detecting that a card is inserted. When the inserted card moves in the extraction direction as described above, the contact member 23a comes into contact with the contact member 23b again, thereby detecting the removal of the card.

図４，図５は、図３に示す、それぞれ矢印Ａ−Ａ、矢印Ｂ−Ｂに沿う各断面図である。   4 and 5 are cross-sectional views taken along arrows AA and BB, respectively, shown in FIG.

図４に示す、矢印Ａ−Ａに沿う断面図上では、スイッチ２３を構成する２つの接点部材２３ａ，２３ｂの双方がコンタクト２２＿３から離れている。ただし、このスイッチ２３を構成する一方の接点部材２３ｂは、図５に示す、矢印Ｂ−Ｂに沿う迂回した経路により繋がっている。すなわち、この接点部材２３ｂは、インサート成形された金属板の必要箇所を切断した後もコンタクト２２＿３と同一の部材で構成されている。このコンタクト２２＿３は、回路基板上のグラウンドに接続されるコンタクトである。接点部材２３ｂも回路基板上のグラウンドに接続される部材であるため、本実施形態では、この接点部材２３ｂを、コンタクト２２＿３と同一の部材で構成して、コンタクト２２＿３の基板接続部２２ｂ＿３を介して回路基板に接続するようにしている。これにより、スイッチ２３を構成する２つの接点部材２３ａ，２３ｂの接触ポイント自体はコンタクト２２＿１〜２２＿６から離れた位置にあっても、一方の接点部材２３ｂの回路基板への接続部分の共平面性が確保されている。   In the cross-sectional view taken along the arrow AA shown in FIG. 4, both of the two contact members 23a and 23b constituting the switch 23 are separated from the contact 22_3. However, one contact member 23b constituting this switch 23 is connected by a detoured route along the arrow BB shown in FIG. That is, the contact member 23b is composed of the same member as the contact 22_3 even after cutting a necessary portion of the insert-molded metal plate. This contact 22_3 is a contact connected to the ground on the circuit board. Since the contact member 23b is also a member connected to the ground on the circuit board, in this embodiment, the contact member 23b is composed of the same member as the contact 22_3, and is connected via the board connection portion 22b_3 of the contact 22_3. It is connected to the circuit board. Thereby, even if the contact point itself of the two contact members 23a and 23b constituting the switch 23 is located away from the contacts 22_1 to 22_6, the coplanarity of the connection portion of the one contact member 23b to the circuit board is improved. It is secured.

スイッチ２３を構成するもう一方の接点部材２３ａの基板接続部は、ハウジング２１に圧入された固定端２３１ａ側にある。この基板接続部の位置はコンタクト２２＿１〜２２＿６の基板接続部２２ａ＿１〜２２ａ＿６から離れているが、ハウジング２１に圧入された部材であり、インサート成形と比べ高い組立精度を有する。このため、この接点部材２３ａの基板接続部についても共平面性が確保されている。   The board connecting portion of the other contact member 23 a constituting the switch 23 is on the fixed end 231 a side press-fitted into the housing 21. The position of the board connecting portion is far from the board connecting portions 22a_1 to 22a_6 of the contacts 22_1 to 22_6. However, the board connecting portion is a member press-fitted into the housing 21, and has higher assembly accuracy than insert molding. For this reason, the coplanarity is ensured also about the board | substrate connection part of this contact member 23a.

このように、本実施形態では、スイッチ２３の一方の接点部材２３ｂをコンタクト２２＿３と同一の部材で構成して回路基板に接続することにより基板接続部の共平面性が確保されている。また、本実施形態によれば、スイッチ２３を構成する２つの接点部材２３ａ，２３ｂのうちの圧入される部材は一方のみであり、前掲の特許文献２のようにスイッチを構成する２つの接点部材の双方を圧入する構成と比べ、工数やコストの低減化が図られる。   As described above, in the present embodiment, one contact member 23b of the switch 23 is formed of the same member as the contact 22_3 and is connected to the circuit board, thereby ensuring coplanarity of the board connecting portion. Further, according to the present embodiment, only one of the two contact members 23a and 23b constituting the switch 23 is press-fitted, and the two contact members constituting the switch as in Patent Document 2 described above. The man-hour and cost can be reduced as compared with the configuration in which both of them are press-fit.
