The main portion 32, the upper wall portion 34, and the bottom wall portion 36 constitute a guide groove 38 that guides the movement of the side edge 210 of the card 200. As expected from FIG. 2, the guide groove 38 has a substantially U-shape when cut along a plane parallel to the YZ plane. The guide groove 38 guides the insertion of the card 200 into the card connector 100 until the leading end of the card 200 abuts against the abutting surface 24 of the base portion 20.

図２に示されるように、ガイド部３０の先端近傍には、保持部５０と、保持部５０と連続するようにして設けられた収容部６０とが形成されている。なお、保持部５０及び収容部６０の詳細についてはアースラグ９０の形状等と関連付けて後に説明することとする。   As shown in FIG. 2, a holding part 50 and a storage part 60 provided so as to be continuous with the holding part 50 are formed in the vicinity of the tip of the guide part 30. The details of the holding unit 50 and the housing unit 60 will be described later in association with the shape of the ground lug 90 and the like.

図２に示されるように、連結部４０は、薄板状の部位であり、ガイド部３０の先端近傍において底壁部３６同士を連結している。   As shown in FIG. 2, the connecting portion 40 is a thin plate-like portion, and connects the bottom wall portions 36 in the vicinity of the tip of the guide portion 30.

図１及び図２に示されるように、各コンタクト７０は、水平部７２及び垂直部７４からなる略Ｌ字形状を有しており、水平部７２がベース部２０の保持孔２２に挿通されることにより、フレーム１０に保持されている。なお、各コンタクト７０がフレーム１０に保持された状態においては、水平部７２はフレーム１０の内部に向かって延びており、垂直部７４は下側（−Ｚ方向）に向かって延びている。   As shown in FIGS. 1 and 2, each contact 70 has a substantially L shape including a horizontal portion 72 and a vertical portion 74, and the horizontal portion 72 is inserted into the holding hole 22 of the base portion 20. Thus, the frame 10 is held. In a state where each contact 70 is held by the frame 10, the horizontal portion 72 extends toward the inside of the frame 10, and the vertical portion 74 extends downward (−Z direction).

図１及び図２に示されるように、ロケータ８０には複数の整列孔８２が形成されており、コンタクト７０の垂直部７４は、この整列孔８２に挿通され、それによって整列させられている。ロケータ８０自体は、フレーム１０の後端近傍に組み込まれ固定されている。   As shown in FIGS. 1 and 2, the locator 80 is formed with a plurality of alignment holes 82, and the vertical portions 74 of the contacts 70 are inserted through the alignment holes 82 and aligned thereby. The locator 80 itself is incorporated and fixed near the rear end of the frame 10.

図２に示されるように、アースラグ９０は、略平板片状の被保持部９１と、被保持部９１から延びる接触片９２とを備えている。詳しくは、被保持部９１には、幅方向内側の斜め上方に向かって延びる係止舌片９３と、下方向に向かって延びる二股係止片９４が設けられている。接触片９２は、略くの字形状を有するように折り曲げ形成されており、くの字の頂部がカード２００のサイドエッジ２１０に設けられたカード電極部２１２と接触する当接部９７として機能する。即ち、本実施の形態における接触片９２は、当接部９７が被保持部９１よりも幅方向内側に向かうように、折り曲げられている。換言すると、接触片９２は、被保持部９１から抜去方向（−Ｘ方向）に向かうと共に幅方向内側に向かって当接部９７まで延びる第１部位９５と、当接部９７から抜去方向に向かうと共に幅方向外側に向かって延びる第２部位９６を備えている。   As shown in FIG. 2, the earth lug 90 includes a substantially flat piece-like held portion 91 and a contact piece 92 extending from the held portion 91. Specifically, the held portion 91 is provided with a locking tongue piece 93 extending obliquely upward on the inner side in the width direction and a bifurcated locking piece 94 extending downward. The contact piece 92 is formed to be bent so as to have a substantially U-shape, and the top of the U-shape functions as a contact portion 97 that comes into contact with the card electrode portion 212 provided on the side edge 210 of the card 200. . That is, the contact piece 92 in the present embodiment is bent so that the contact portion 97 is directed inward in the width direction relative to the held portion 91. In other words, the contact piece 92 extends from the held portion 91 in the removal direction (−X direction) and extends inward in the width direction to the contact portion 97 and from the contact portion 97 in the removal direction. And a second portion 96 extending outward in the width direction.

図２乃至図６に示されるように、上述した本実施の形態による保持部５０及び収容部６０は、上記構成を有するアースラグ９０を保持収容するための部位である。保持部５０は、厚み方向に延びるスリットを有している。保持部５０の幅方向内側の壁上には係止部５２として機能する段差が形成されており、保持部５０のスリットの底部５０ａにはフレーム１０の下面まで貫通する孔５４が形成されている。アースラグ９０の二股係止片９４を孔５４から下方向に突出させつつ被保持部９１の部位９１ｂが保持部５０のスリットの底部５０ａに当接するまで被保持部９１を保持部５０に挿入すると、被保持部９１のＸ方向端部に形成された圧入部９１ａが保持部５０のＸ方向で対向する壁に食い込み、それによってアースラグ９０の被保持部９１が保持部５０に保持される。この保持部５０に対する被保持部９１の挿入の際、係止舌片９３は、保持部５０の内壁からＹ方向外側に向かう力を受けて一時的に変形するが係止舌片９３の端部が保持部５０の係止部５２に達すると、再び元の形に戻ろうとする。それによって係止舌片９３の端部は係止部５２に係止することになり、圧入部９０ａの機能と相俟って保持部５０による被保持部９１の保持をより強固なものとする。   As shown in FIGS. 2 to 6, the holding unit 50 and the storage unit 60 according to the present embodiment described above are portions for holding and storing the ground lug 90 having the above-described configuration. The holding part 50 has a slit extending in the thickness direction. A step functioning as a locking portion 52 is formed on the inner wall in the width direction of the holding portion 50, and a hole 54 penetrating to the lower surface of the frame 10 is formed in the bottom portion 50 a of the slit of the holding portion 50. . When the held portion 91 is inserted into the holding portion 50 until the portion 91b of the held portion 91 abuts against the bottom portion 50a of the slit of the holding portion 50 while projecting the bifurcated locking piece 94 of the ground lug 90 downward from the hole 54, A press-fit portion 91 a formed at the X-direction end of the held portion 91 bites into a wall facing the holding portion 50 in the X direction, whereby the held portion 91 of the earth lug 90 is held by the holding portion 50. When the held portion 91 is inserted into the holding portion 50, the locking tongue piece 93 is temporarily deformed by receiving a force from the inner wall of the holding portion 50 toward the outside in the Y direction. When it reaches the locking part 52 of the holding part 50, it tries to return to its original shape again. As a result, the end portion of the locking tongue piece 93 is locked to the locking portion 52, and the holding portion 91 is more firmly held by the holding portion 50 in combination with the function of the press-fit portion 90a. .

収容部６０は、特に図３乃至図６に示されるように、アースラグ９０の接触片９２を収容するためのものである。この収容部６０には、収容部６０の内壁からガイド溝３８まで貫通する窓部６２が形成されている。本実施の形態における窓部６２の位置及び形状は、特に図５及び図６に示されるように、アースラグ９０の被保持部９１が保持部５０に保持された状態において、アースラグ９０の接触片９２に設けられた当接部９７の下部９７ａのみが窓部６２を通じてガイド溝３８内に突出するようにして、定められている。換言すると、本実施の形態による当接部９７の上部９７ｂは、被保持部９１が保持部５０に保持された状態において、窓部６２の上側に位置しているためガイド溝３８内には突出していない。   The accommodating part 60 is for accommodating the contact piece 92 of the earth lug 90 as especially shown by FIG. 3 thru | or FIG. A window portion 62 that penetrates from the inner wall of the accommodating portion 60 to the guide groove 38 is formed in the accommodating portion 60. The position and shape of the window portion 62 in the present embodiment is such that the contact piece 92 of the earth lug 90 is in a state where the held portion 91 of the earth lug 90 is held by the holding portion 50 as shown in FIGS. Only the lower portion 97a of the abutting portion 97 provided in the upper portion is defined so as to protrude into the guide groove 38 through the window portion 62. In other words, the upper portion 97b of the contact portion 97 according to the present embodiment protrudes into the guide groove 38 because it is located above the window portion 62 when the held portion 91 is held by the holding portion 50. Not.

詳しくは、本実施の形態における収容部６０は、上方から見た場合に、接触片９２と同様にくの字状に延びる内壁を有している。この収容部６０のくの字状の内壁のうち、窓部６２の上側の部分は、幅方向において、当接部９７の上部９７ｂの内側に位置しており、接触片保護部６４として機能する。   In detail, the accommodating part 60 in this Embodiment has the inner wall extended in the shape of a dogleg like the contact piece 92, when it sees from upper direction. Of the inner wall of the container-shaped portion 60, the upper portion of the window portion 62 is located inside the upper portion 97 b of the contact portion 97 in the width direction, and functions as the contact piece protection portion 64. .

図４及び図５から理解されるように、本実施の形態による接触片保護部６４は上壁部３４に形成されている。また、本実施の形態による接触片保護部６４のくの字状の頂部よりも挿入方向（Ｘ方向）奥側の部位６４ａは、当接部９７からみて挿入方向奥側で且つ幅方向外側に位置している。そのため、カード２００のイレギュラーな挿入動作が行われた場合であっても、アースラグ９０の接触片９２は接触片保護部６４と接触するため、それ以上変位することがない。従って、アースラグ９０の接触片９２の座屈等の変形を確実に防止することができる。   As can be understood from FIGS. 4 and 5, the contact piece protection portion 64 according to the present embodiment is formed on the upper wall portion 34. In addition, the portion 64a on the back side in the insertion direction (X direction) of the contact piece protection portion 64 according to the present embodiment is located on the back side in the insertion direction and outside in the width direction as viewed from the contact portion 97. positioned. Therefore, even when the irregular insertion operation of the card 200 is performed, the contact piece 92 of the ground lug 90 is in contact with the contact piece protection part 64 and thus is not displaced further. Therefore, deformation such as buckling of the contact piece 92 of the earth lug 90 can be reliably prevented.

なお、本実施の形態における接触片保護部６４は幅方向において当接部９７の上部９７ｂのすべてと重なるように構成されているが（図５参照）、例えば、接触片保護部６４の挿入方向奥側の部位６４ａのみが当接部９７の上部９７ｂと幅方向において重なることとしてもよい。接触片９２を座屈等させるような力は当接部９７を挿入方向に移動させるようなものであるのに対して、接触片保護部６４の部位６４ａは当接部９７の挿入方向へ向かう移動を規制する役割を果たすからである。但し、接触片保護部６４の強度の向上や接触片９２の座屈防止をより確実なものとするためには、本実施の形態のように、接触片保護部６４が幅方向において当接部９７の上部９７ｂのすべてと重なるように構成されていることが好ましい。   In addition, although the contact piece protection part 64 in this Embodiment is comprised so that it may overlap with all the upper parts 97b of the contact part 97 in the width direction (refer FIG. 5), for example, the insertion direction of the contact piece protection part 64 Only the rear portion 64a may overlap the upper portion 97b of the contact portion 97 in the width direction. The force for buckling the contact piece 92 is for moving the contact portion 97 in the insertion direction, whereas the portion 64a of the contact piece protection portion 64 is directed in the insertion direction of the contact portion 97. This is because it plays a role in regulating movement. However, in order to improve the strength of the contact piece protection portion 64 and prevent buckling of the contact piece 92 more reliably, the contact piece protection portion 64 is a contact portion in the width direction as in the present embodiment. 97 is preferably configured to overlap all of the upper part 97b of 97.
