The card connector 1 that is provided with above-mentioned card guide is commonly referred to propelling/push type or push away-pushing-type connector, when card 101 inserts card connector 1 and when card 101 is when card connector 1 is discharged, all needs card 101 to push inward.This operation is similar in appearance to the blocked operation in a push-button switch field (position maintenance, push away connect deduction).The collaborative movement of bar member 81 and cam groove 22 makes and blocks 101 together with mobile sliding component 23 execution one push away-push operation.Thus, when by push the operation of card 101 to direction of insertion, card 101 is moved and during incoming terminal point along direction of insertion, described card guide can make by the active force of force application component 82 card 101 move along the direction contrary with direction of insertion from described end point, thereby discharges card 101.In latched position, sliding component 23 stops (in place), thereby card 101 is remained on to the inside of card connector 1.

The downward active force that bar member 81 is applied from top by a bar pressing member 75 of housing 71 keeps.Bar pressing member 75 is flexible tabular components that form by a part for housing 71 being carried out to bending process, with can be towards the direction application of force of the bottom wall portion 11b of pedestal 11, and bar member 81 be held between bar pressing member 75 and sliding component 23 or pedestal 11 and not depart from the mode of pedestal 11 or sliding component 23.

In addition, housing 71 has the shape of a general rectangular, and comprises towards a top plate portion 72 of card 101 upper surface 111b and from the vertical a plurality of side plates 74 established in many places of the lateral margin of top plate portion 72.A plurality of snap open 73 are formed at side plate 74, and, as shown in Figure 1A, Figure 1B and Fig. 2 A, Fig. 2 B, when housing 71 is installed on the upside of pedestal 11, be formed at the snap projection 13 and snap open 73 buckles of the outer surfaces such as side wall portion 11e of pedestal 11, thereby housing 71 is fixed on pedestal 11.From the outward extending stator 78 of housing 71 can be formed at one on the circuit board etc. of electronic equipment and fixingly by pad grade, be connected.Together with bar pressing member 75, as a peripherally ported bar, to press peripheral openings 75a and be formed at top plate portion 72, described bar is pressed the spin-off that peripheral openings is the forming process of bar pressing member 75.

And, at top plate portion 72, being formed with as the housing shell fragment portion 76 that presses card division, and being formed with as the peripherally ported shell fragment peripheral openings 76a of portion, the peripheral openings 76a of shell fragment portion is the spin-off of the forming process of housing shell fragment portion 76.Housing shell fragment portion 76 comprises: contact arm 76b, and it is cantilever type plate member, its cardinal extremity is connected in top plate portion 72; And leading section 76c, its free end for contact arm 76b is front end, thereby and oblique downward-extension make leading section 76c towards a front-end edge 71f of housing 71.And when card 101 does not insert card insertion space, at least the lower surface of leading section 76c is positioned at the below of the lower surface of top plate portion 72.Housing shell fragment portion 76 is arranged near the position of an end edge 71r of housing 71.Particularly, leading section 76c is located in the direction of insertion of card 101 than the position of the more close end edge 71r in centre of the front-end edge 71f of housing 71 and end edge 71r.

In the example shown in figure, have two housing shell fragment portions 76, but have one or three or more housing shell fragment portion 76 also passable.If have a plurality of housing shell fragment portion 76, they are preferably arranged in a row along end edge 71r on the Width of housing 71 so.

And housing shell fragment portion 76 is set to leading section 76c at least and contacts with the upper surface 111b of card 101 in card connector 1 interior maintenance.Leading section 76c preference is as contacted with card 101 upper surface 111b as upper/lower positions, and this position is than the contact site 51c of backside terminals 51 and the position of blocking 101 the position of contact pad contact and the contact site 61c of front side terminal 61 and blocking the more close end edge 71r in centre between the position that 101 contact pad contacts in the direction of insertion of card 101.In addition, leading section 76c preferably contacts with the upper surface 111b that blocks 101 accommodating recess 11j position in opposite directions with the welding afterbody that is formed at bottom wall portion 11b in card 101 direction of insertion.

In addition, the contact arm 76b of the function of performance cantilever type shell fragment portion is arranged to contact site 51c that the addendum modification of leading section 76c on above-below direction be at least greater than backside terminals 51 addendum modification on above-below direction.Particularly, make from the cardinal extremity that contacts arm 76b longer to the length of leading section 76c that contacts arm 76b,, make elastic reaction length longer, thereby the flexibility of described shell fragment portion is increased, leading section 76c can plastic deformation on above-below direction thus, and increases the addendum modification of leading section 76c on above-below direction.For example, the length of the contact arm 76b of housing shell fragment portion 76 is preferably long than the contact arm 51b of backside terminals 51.

Like this, housing shell fragment portion 76 contacts with the upper surface 111b of card 101 in remaining on card connector 1 and to blocking 101 active forces that apply downward, press card 101, thereby maintain reliably the contact between the contact pad of card 101 and the contact site 61c of the contact site 51c of backside terminals 51 and front side terminal 61.Especially reliably maintain the contact between the contact pad of card 101 and the contact site 51c of backside terminals 51.

In addition, a card detecting switch is arranged near the front-end edge 11f of pedestal 11, and for detection of the contact pad of card 101 and the contact between backside terminals 51 and front side terminal 61, thereby test card 101 is arranged in card connector 1.Described card detecting switch is formed by one second contact member 63 that is installed on inner wall part 11a and near one first contact member 62 thereof and is installed on bottom wall portion 11b.

The first contact member 62 comprises: an installation portion 62a, is installed on inner wall part 11a; One cantilever type body 62b, one cardinal extremity is connected in installation portion 62a and extends along transverse direction; And a contact site 62c, be connected in the free end of body 62b.Installation portion 62a is in substantially parallel relationship to the side of inner wall part 11a, and when card 101 is not while inserting card connector 1, and the front side that body 62b is positioned at respect to the described laterally inclined and contact site 62c of inner wall part 11a in the direction of insertion of card 101 is rear.When card 101 inserts, block 101 front end in contact body 62b.

On the other hand, the second contact member 63 comprises: a flat installation portion 63a, is installed near the part inner wall part 11a of bottom wall portion 11b; One cantilever type body 63b, its cardinal extremity is connected in installation portion 63a and extends along transverse direction; And a contact site 63c, be connected in the free end of body 62b.Installation portion 63a is in substantially parallel relationship to the upper surface of bottom wall portion 11b, and when card 101 does not insert card connector 1, described upper surface and contact site 63c that body 63b is also in substantially parallel relationship to bottom wall portion 11b are positioned near the position of inner wall part 11a.

And when card 101 does not insert, as shown in Figure 3 and Figure 4, the first contact member 62 does not contact with the second contact member 63, the not conducting of described card detecting switch that is to say in closing (OFF) state.

But, when position that card 101 inserts and contacts with backside terminals 51 and front side terminal 61 to the contact pads of Dacca 101, the cantilever type body 62b of the first contact member 62 is blocked that 101 front end is pushed the direction of inner wall part 11a to and displacement makes the contact site 62c of the first contact member 62 contact with the contact site 63c of the second contact member 63.Thereby the first contact member 62 contacts with the second contact member 63, and described card detecting switch conducting, that is to say in connecting (ON) state.

Next, the operation of the card connector 1 with above-mentioned formation is described.First, the operation of inserting card 101 is described.

Fig. 5 A, Fig. 5 B are the figure that one of explanation the first embodiment of the present utility model blocks the state not inserting, and Fig. 6 A, Fig. 6 B are the figure that one of explanation the first embodiment of the present utility model blocks the state inserting.In addition, Fig. 5 A, Fig. 6 A are a vertical view, and Fig. 5 B, Fig. 6 B are an amplification view of making along the line of arrow A, A and B in connection layout 5A, Fig. 6 A, B.

When card 101 does not insert card insertion space, as shown in Fig. 5 A, Fig. 5 B, the front end of contact arm 51b and the front end that contacts arm 61b of front side terminal 61 of backside terminals 51 extend obliquely towards front-end edge 11f, and the upper surface of the upper surface of at least contact site 51c of backside terminals 51 and at least contact site 61c of front side terminal 61 is positioned at the top of the upper surface of bottom wall portion 11b.Because the contact arm 51b of backside terminals 51 is short, the contact site 51c of backside terminals 51 only protrudes from the top of the upper surface of bottom wall portion 11b a little.On the other hand, because the contact arm 61b of front side terminal 61 is long, so the contact site 61c of front side terminal 61 protrudes from the top of the upper surface of bottom wall portion 11b to a greater degree than the contact site 51c of backside terminals 51.

In addition, the front end of the contact arm 76b of housing shell fragment portion 76 is towards the oblique downward-extension of front-end edge 71f, and the lower surface of at least leading section 76c of housing shell fragment portion 76 is lower than the lower surface of top plate portion 72.And, the leading section 76c of housing shell fragment portion 76 from the lower surface of the top plate portion 72 contact site 51c that outstanding amount is greater than backside terminals 51 downwards from the upper surface of bottom wall portion 11b outstanding amount upward.

First, a user is such as card 101 being inserted and is formed in the card insertion space between pedestal 11 and housing 71 via the insert port 18 at the rear of card connector 1 with finger etc.Card 101 inserts to the front-end edge 11f of pedestal 11, the posture (orientation) of blocking 101 the lower surface top plate portion 72 towards bottom wall portion 11b, upper surface 111b towards housing 71 to block 101 front end face.Card 101 moves forward along card guide resettlement section 11h thus.

Then, when user further inwardly pushes away card 101, the lateral margin maintaining part 23b of sliding component 23 and front end maintaining part 23c keep lateral margin and the front end of card 101, thereby block 101, kept and towards inner wall part 11a, move together with sliding component 23 by sliding component 23.Now, user points applied pressure and from the front end that blocks 101, is passed to sliding component 23 by front end maintaining part 23c.Then, the force application component 82 that sliding component 23 compressions consist of helical spring, therefore, sliding component 23 and card 101 counter-forces that are subject to from force application component 82; But, because this counter-force is less than user, the applied pressure such as point, so sliding component 23 and card 101 overcome counter-force and move.Now, sliding component 23 slides along card guide resettlement section 11h, blocks 101 and moves forward together with sliding component 23.After sliding component 23 and card 101, arrive as one of advanced positions farthest and cross stroke (over stroke) position and cross stroke state in one.

Then, when user stops pushing away card 101 and removes while being applied to the pressure on card 101, the counter-force being applied by force application component 82 makes sliding component 23 and card 101 edges rearward move away from the direction of inner wall part 11a.Sliding component 23 and card 101 remain on a latched position subsequently, in this latched position, block 101 in card connector 1 in a lock-out state.This is that the free end of the bar member 81 that engages due to the cam groove 22 with being formed on the upper surface of slide cam part 21 is snapped in the part of cam groove 22 and the motion of limit slippage member 23, thereby sliding component 23 is locked in to latched position.

And, block 101 by being held in latched position, in can and be provided with card connector 1 electronic equipment such as arithmetic element etc. between the state that transmits and receive data.When card 101 is while being held in latched position, reach the state shown in Fig. 6 A, Fig. 6 B, and the backside terminals 51 of card connector 1 and contact site 51c, the 61c of front side terminal 61 contact and conducting with the contact pad of card 101.

At this, because the contact arm 61b length of front side terminal 61 relatively length have longer elastic reaction length, therefore, the contact arm 61b of the effect of performance cantilever type shell fragment portion has high flexibility, and contact site 61c has larger addendum modification on above-below direction.Therefore, as shown in Fig. 6 A, Fig. 6 B, when contact site 61c is due to card 101 during displacement downwards, as the larger elastic acting force of contact arm 61b performance of the shell fragment portion of strain, therefore, contact site 61c applies larger active force upwards to blocking 101 contact pad.Therefore, maintain reliably the contact between contact site 61c and the contact pad of the card 101 corresponding with contact site 61c.

On the other hand, because the contact arm 51b length of backside terminals 51 is relatively short, there is shorter elastic reaction length, therefore, the contact arm 51b of the effect of performance cantilever type shell fragment portion has low flexibility, and contact site 51c has less addendum modification on above-below direction.Therefore, as shown in Fig. 6 A, Fig. 6 B, when contact site 51c is due to card 101 during displacement downwards, as the contact arm 51b of the shell fragment portion of strain, can only bring into play less elastic acting force, therefore, contact site 51c applies less active force upwards to blocking 101 contact pad.

But, because the contact arm 76b length of housing shell fragment portion 76 relatively length have long elastic reaction length, therefore, the contact arm 76b of the effect of performance cantilever type shell fragment portion has high flexibility, and the addendum modification of leading section 76c on the above-below direction addendum modification of contact site 51c on above-below direction that be greater than backside terminals 51.Therefore, as shown in Fig. 6 A, Fig. 6 B, when leading section 76c is because blocking 101 while making progress displacement, the larger elastic acting force of contact arm 76b performance as the shell fragment portion of strain, therefore, the contact arm 76b that comprises leading section 76c applies downward larger active force to blocking 101,, with larger active force, presses card 101 that is.

At this, housing shell fragment portion 76 is arranged on the position near an end edge 71r of housing 71.In the example shown in figure, leading section 76c is contacting with the upper surface 111b of card 101 as upper/lower positions, this position is than the contact site 51c of backside terminals 51 with block 101 the position of contact pad contact and the contact site 61c of front side terminal 61 and the welding afterbody that blocks the ，Gai position, position of the more close end edge 71r in centre between the position that 101 contact pad contacts and be formed at bottom wall portion 11b is accommodated recess 11j in opposite directions in card 101 direction of insertion.By housing shell fragment portion 76, be applied to the effect of the position that contact site 61c that the effect of the position that downward active force on card 101 contact in the contact site 51c of backside terminals 51 and the contact pad of card 101 is thus greater than at front side terminal 61 contacts with the contact pad of blocking 101.

The contact site 51c of backside terminals 51 and card 101 contact pad are subject to together thus the contacting the active force that active force that arm 51b applies and housing shell fragment portion 76 apply of backside terminals 51 and press mutually, thereby maintain reliably the contact between the contact site 51c of backside terminals 51 and the contact pad of the card 101 corresponding with contact site 51c.

The part that housing shell fragment portion 76 is applied to the downward active force on card 101 also acts on the position that the contact site 61c of front side terminal 61 and the contact pad of card 101 contacts, thus the contact site 61c of front side terminal 61 and block 101 contact pad and be also subject to together the contacting a part of active force that active force that arm 61b applies and housing shell fragment portion 76 apply of front side terminal 61 and press mutually.Thereby the contact between the contact site 61c of front side terminal 61 and the contact pad of the card 101 corresponding with contact site 61c is maintained more reliably.

In addition, the body 62b of the first contact member 62 of described card detecting switch is blocked 101 front end and is released and antedisplacement, and the free-ended contact site 62c that is connected in body 62b contacts with the contact site 63c of the second contact member 63.Thereby the first contact member 62 contacts with the second contact member 63, described card detecting switch is in connecting (ON) state.

Yet, when a user pushes away card 101, conventionally with finger, wait the rear end 111r that pushes away card 101.If forming, the bottom wall portion 11b of pedestal 11 on fore-and-aft direction, there is the length of a length and the rear that end edge 11r is positioned at the rear end 111r of the card 101 that is held in latched position, so when user pushes to the mistake travel position in latched position the place ahead by card 101, finger is by the end edge 11r of contact pedestal 11, and this will hinder the carrying out of push operation.That is, this will cause operability to reduce.

But, as mentioned above, according to card connector 1 of the present utility model, can make to keep to backside terminals from end edge 11r the distance of contact site 51c of the backside terminals 51 in recess 11c shorter, therefore, even if certainly block 101 rear end 111r, only there is a little distance near the contact pad 111r of this rear end, when card 101 marched to travel position, do not need to make the rear end 111r of card 101 further to insert and cross end edge 11r forward.Therefore, operability can not reduce.

Afterwards, the operation that instruction card 101 is discharged from card connector 1.

First, when a user pushes away card 101 with finger etc., move towards inner wall part 11a sliding component 23 and card 101 self-locking positions.Then, when user further pushes away card 101, sliding component 23 and card 101 arrive advanced positions farthest and cross travel position and cross stroke state in one.

Then, when user stops pushing away the operation of card 101 and removes the pressure being applied on card 101, the active force being applied by force application component 82 makes the sliding component 23 and the card 101 that were positioned at travel position move along the direction away from inner wall part 11a, and this makes them along the direction contrary with direction of insertion, move.Sliding component 23 and card 101, then by latched position and further move backward, are discharged from insert port 18 thereby block 101.

In the present embodiment, as mentioned above, card connector 1 comprises: a pedestal 11, for accommodating a card 101 that is provided with a plurality of contact pads; A plurality of backside terminals 51 and a plurality of front sides terminal 61, be arranged on pedestal 11, contacts with described a plurality of contact pads of card 101; And a housing 71, be installed on pedestal 11, at least covering pedestal 11 and inserting the part of the card 101 of pedestal 11.Backside terminals 51 is provided with: base portion 51a, arranges and be installed on the bottom wall portion 11b of pedestal 11 along the end edge 11r of pedestal 11; Cantilever type contact arm 51b, its cardinal extremity be connected in base portion 51a and certainly this cardinal extremity towards the front-end edge 11f of pedestal 11, extend; And contact site 51c, contact site 51c is connected with the front end that contacts arm 51b, and contacts with the contact pad of card 101.Housing 71 is provided with: a top plate portion 72, with card 101 upper surface 111b in opposite directions; And housing shell fragment portion 76, be formed at top plate portion 72.Housing shell fragment portion 76 is provided with: cantilever type contact arm 76b, its cardinal extremity be connected in top plate portion 72 and certainly this cardinal extremity towards the front-end edge 71f of housing 71, extend; And the leading section 76c of contact arm 76b.And the addendum modification of leading section 76c is greater than the addendum modification of the contact site 51c of the backside terminals 51 arranging along the end edge 11r of pedestal 11.

Thus, the contact site 51c of backside terminals 51 can be arranged on near the position end edge 11r of pedestal 11 of card connector 1, even if certainly block 101 rear end 111r, only there is a short distance near the contact pad 111r of rear end, when card 101 inserts card connector 1, do not need the rear end 111r of card 101 further to insert and cross end edge 11r forward yet, this makes card 101 easily insert and discharge, and improves operability.In addition, because 76 pairs of card 101 active forces that apply towards the bottom wall portion 11b of pedestal 11 of housing shell fragment portion, therefore the contact between the contact site 51c of backside terminals 51 and the contact pad of card 101 increases, and the contact between them is maintained reliably, and higher reliability is provided thus.

In addition, when card 101 is not while inserting pedestal 11, the contact site 51c of the backside terminals 51 arranging along the end edge 11r of pedestal 11 is less than housing shell fragment portion 76 from the bottom wall portion 11b of pedestal 1 leading section 76c towards the outstanding amount of top plate portion 72 from top plate portion 72 towards the outstanding amount of bottom wall portion 11b.Result, the addendum modification of the contact site 51c of backside terminals 51 is less than the addendum modification of the leading section 76c of housing shell fragment portion 76, the contact arm 76b of housing shell fragment portion 76 applies a large elastic acting force, therefore, housing shell fragment portion 76 can apply downward larger active force to blocking 101, can press card 101 with larger active force.

In addition, housing shell fragment portion 76 is arranged near the position of an end edge 71r of housing 71.The contact site 51c of backside terminals 51 and card 101 contact pad are subject to together thus the contacting the active force that active force that arm 51b applies and housing shell fragment portion 76 apply of backside terminals 51 and press mutually, thus the contact site 51c that maintains reliably backside terminals 51 with and the contact pad of the corresponding card 101 of contact site 51c between contact.

In addition, also there is near the front side terminal 61 of front-end edge 11f that is configured in pedestal 11, the leading section 76c of housing shell fragment portion 76 is contacting with card 101 upper surface 111b as upper/lower positions, and this position is than the contact site 51c of backside terminals 51 and the position of blocking 101 the position of contact pad contact and the contact site 61c of front side terminal 61 and blocking the end edge 71r of the more close housing 71 in centre between the position that 101 contact pad contacts.Thus, a part that is applied to the downward active force on card 101 by housing shell fragment portion 76 also acts on the position that the contact site 61c of front side terminal 61 and the contact pad of card 101 contacts, thus the contact site 61c of front side terminal 61 and block 101 contact pad and be subject to together the contacting a part of active force that active force that arm 61b applies and housing shell fragment portion 76 apply of front side terminal 61 and press mutually.

In addition, the addendum modification of the contact site 61c of front side terminal 61 is greater than the addendum modification of the contact site 51c of backside terminals 51.Contact between the contact pad of the contact site 61c of front side terminal 61 and the card corresponding with contact site 61c 101 is maintained thus reliably.

Next one second embodiment of the present utility model is described.The identical sign flag for parts with the structure identical with the first embodiment, and the description thereof will be omitted, also omits the operation identical with the first embodiment and the explanation of effect.

Fig. 7 is according to a stereogram of a card connector of one second embodiment of the present utility model.

In this embodiment, there is single (only one) housing shell fragment portion 76, as is shown in this figure.Housing shell fragment portion 76 comprises: a pair of contact arm 76b, and its cardinal extremity is connected in top plate portion 72, is cantilever type tabular component; A junction 76d, for connecting the free end of described a pair of contact arm 76b; And leading section 76c, be the free end of contact arm 76b, be also the free end of connecting portion 76d simultaneously.Described a pair of contact arm 76b is divided into one first contact arm 76b1 and contacts arm 76b2 with one second.In addition, be formed with by top plate portion 72, the first contact arm 76b1 and contact arm 76b2 and a connecting portion 76d delimitation inner opening 76e of shell fragment portion around with second, housing shell fragment portion 76 has the flat shape of a cardinal principle コ word shape or U-shaped.

Other aspects of the structure of card connector 1 and operation are similar in appearance to the first embodiment, and therefore the description thereof will be omitted.

As mentioned above, the present embodiment has a single housing shell fragment portion 76, but the effect of the free end performance leading section 76c of the connecting portion 76d extending due to Width along card connector 1, the elastic acting force that therefore, contact arm 76b can be applied puts in the wider scope on the Width of upper surface 111b of the card 101 that inserts card insertion space.Because contact arm 76b is divided into the first contact arm 76b1 and contact arm 76b2 with second, so contact arm 76b2 width separately with second as the first contact arm 76b1 of cantilever type shell fragment portion, can reduce, thereby make the flexibility raising of shell fragment portion.Other aspects of the effect of the present embodiment are similar in appearance to the first embodiment, and therefore the description thereof will be omitted.

Next of the present utility model 1 the 3rd embodiment is described.The identical sign flag for parts with the structure identical with the second embodiment with the first embodiment, and the description thereof will be omitted, also omits the operation identical with the second embodiment with the first embodiment and the explanation of effect.

Fig. 8 A, Fig. 8 B are according to a stereogram of a card connector of of the present utility model 1 the 3rd embodiment; Fig. 9 A, Fig. 9 B are the two-sided view according to the card connector of the 3rd embodiment of the present utility model; Figure 10 is for representing according to the plan view of the state of removing housing of the card connector of the 3rd embodiment of the present utility model; And Figure 11 is for representing according to the stereogram of the state of removing housing of the card connector of the 3rd embodiment of the present utility model.In addition, Fig. 8 A illustrates that a card does not insert state wherein and Fig. 8 B illustrates a card and inserts state wherein.Fig. 9 A is a vertical view and Fig. 9 B is an end view.

Therefore in this embodiment, identical with the situation of the first embodiment, the length of the contact arm 51b of backside terminals 51 is shorter, can make the distance to contact site 51c from the rear end of backside terminals 51 reduce.Therefore,, if backside terminals keeps recess 11c to be formed near the end edge 11r of pedestal 11, can make the distance to contact site 51c from end edge 11r reduce, as shown in Figure 10 and Figure 11.As a result, even if certainly block 101 rear end 111r, only have a short distance near the contact pad 111r of rear end, also can make to be inserted into card connector 1 card 101 rear end 111r from the end edge 11r of pedestal 11 rearward outstanding amount reduce, as shown in Fig. 8 B.In addition,, when card 101 inserts card connector 1, do not need the rear end 111r of card 101 further to insert forward the end edge 11r that crosses pedestal 11.

But, because the contact arm 51b length as cantilever type shell fragment portion is shorter, therefore have shorter elastic reaction length, the little and contact site 51c of the flexibility of described shell fragment portion is difficult for flexible displacement on above-below direction, so the addendum modification of contact site 51c on above-below direction reduces.

In the present embodiment, the contact arm 61b length of front side terminal 61 is also shorter, as the situation of backside terminals 51.As shown in figure 10, the contact arm 61b of front side terminal 61 has the length identical with the contact arm 51b cardinal principle of backside terminals 51.As a result, the degree of freedom of the setting position of front side terminal 61 in the direction of insertion of card 101 increases, and the degree of freedom of the design of card connector 1 increases.The length of card connector 1 can reduce.

But, because the contact arm 61b as cantilever type shell fragment portion of the front side terminal 61 of the present embodiment is also with the situation of backside terminals 51, length is shorter in the same manner, there is short elastic reaction length, therefore the flexibility of described shell fragment portion is low, and contact site 61c is difficult for flexible displacement on above-below direction, the addendum modification of contact site 61c on above-below direction reduces.Therefore, when contact site 61c is due to card 101 during displacement downwards, as the situation of backside terminals 51, contact arm 61b as the shell fragment portion of strain only produces a relatively little elastic acting force, therefore contact site 61c applies less active force upwards to blocking 101 contact pad, with less active force, presses card 101.

Therefore, in the present embodiment, the position near the top plate portion 72 front-end edge 71f of housing 71 is also formed with housing shell fragment portion 76.Particularly, in the present embodiment, housing shell fragment portion 76 is not only arranged near position end edge 71r, is also arranged near the position of front-end edge 71f, and is set to form two rows that extend along the Width of card connector 1.

The housing shell fragment portion 76 that is arranged near position front-end edge 71f be the housing shell fragment portion 76 of front side have be arranged on end edge 71r near the housing shell fragment portion 76 of position be the identical structure of the housing shell fragment portion 76 of rear side, the explanation of therefore omitting its structure.

The leading section 76c of the housing shell fragment portion 76 of front side is preferably contacting with card 101 upper surface 111b as upper/lower positions, and this position is than the contact site 51c of backside terminals 51 and the position of blocking 101 the position of contact pad contact and the contact site 61c of front side terminal 61 and blocking the more close front-end edge 71f in centre between the position that 101 contact pad contacts in the direction of insertion of card 101.The leading section 76c of the housing shell fragment portion 76 of front side is more preferably contacting with card 101 upper surface 111b as upper/lower positions, and this position is the position of the more close front-end edge 71f in position that contacts with the contact pad of blocking 101 than the contact site 61c of front side terminal 61 in the direction of insertion of card 101.

Other aspects of described structure are identical with the first embodiment, and therefore the description thereof will be omitted.

Then, illustrate according to the operation of the card connector 1 of the present embodiment.

Figure 12 A, Figure 12 B illustrate one of the 3rd embodiment of the present utility model and block the state not inserting; Figure 13 A, Figure 13 B illustrate the state of a card insertion of the 3rd embodiment of the present utility model.Figure 12 A, Figure 13 A are a vertical view and Figure 12 B, Figure 13 B amplification view for making along the line of arrow C, C and D in connection layout 12A, Figure 13 B, D.

When card 101 does not insert card insertion space, as shown in Figure 12 A, Figure 12 B, the front end of contact arm 51b and the front end that contacts arm 61b of front side terminal 61 of backside terminals 51 extend obliquely towards front-end edge 11f, and the upper surface of the upper surface of at least contact site 51c of backside terminals 51 and at least contact site 61c of front side terminal 61 is positioned at the top of the upper surface of bottom wall portion 11b.In addition because the contact arm 51b of backside terminals 51 and front side terminal 61 to contact arm 61b length all shorter, so the contact site 51c of backside terminals 51 and the contact site 61c of front side terminal 61 only protrude from the top of the upper surface of bottom wall portion 11b a little.

Outside woods, the front end that contacts arm 76b of the front end of the contact arm 76b of the housing shell fragment portion 76 of rear side and the housing shell fragment portion 76 of front side is all towards the oblique downward-extension of front-end edge 71f, and the lower surface of at least leading section 76c of the lower surface of at least leading section 76c of the housing shell fragment portion 76 of rear side and the housing shell fragment portion 76 of front side is lower than the lower surface of top plate portion 72.The leading section 76c of the leading section 76c of the housing shell fragment portion 76 of rear side and the housing shell fragment portion 76 of front side from the lower surface of top plate portion 72 downwards outstanding amount be greater than the contact site 51c of backside terminals 51 and the contact site 61c of front side terminal 61 from the upper surface of bottom wall portion 11b outstanding amount upward.

In addition, the operation that user inserts the card insertion space between pedestal 11 and housing 71 by card 101 via the insert port 18 at card connector 1 rear is identical with the first embodiment, and therefore the description thereof will be omitted.

But, because the length that contacts arm 76b of the contact arm 76b of the housing shell fragment portion 76 of rear side and the housing shell fragment portion 76 of front side is long and have long elastic reaction length, therefore the flexibility of contact arm 76b of effect of bringing into play cantilever type shell fragment portion is high, and the addendum modification of leading section 76c on above-below direction is greater than the contact site 51c of backside terminals 51 and the addendum modification of the contact site 61c of front side terminal 61 on above-below direction.Therefore, when leading section 76c makes progress displacement due to card 101, as shown in Figure 13 A, Figure 13 B, contact arm 76b as the shell fragment portion of strain produces a large elastic acting force, therefore, the contact arm 76b that comprises leading section 76c applies downward larger active force to blocking 101, with larger active force, presses card 101.

At this, the housing shell fragment portion 76 of rear side is arranged near the position of end edge 71r of housing 71, and the housing shell fragment portion 76 of front side is arranged near the position of front-end edge 71f of housing 71.In the example shown in this figure, the leading section 76c of the housing shell fragment portion 76 of rear side is contacting with the upper surface 111b of card 101 as upper/lower positions, this position be in card 101 direction of insertion than the contact site 51c of backside terminals 51 and block 101 the position of contact pad contact and the contact site 61c of front side terminal 61 and position that the welding afterbody that blocks the ，Gai position, position of the more close end edge 71r in centre between the position that 101 contact pad contacts and be formed at bottom wall portion 11b is accommodated recess 11j in opposite directions.In addition, the leading section 76c of the housing shell fragment portion 76 of front side is contacting with the upper surface 111b of card 101 as upper/lower positions, this position is than the contact site 51c of backside terminals 51 with block the more close front-end edge 71f in position that the ，Gai position, position of the more close front-end edge 71f in centre between the position that the position of 101 contact pad contact contact with the contact site 61c of front side terminal 61 and the contact pad of card contacts with the contact pad of blocking 101 than the contact site 61c of front side terminal 61 in card 101 direction of insertion.

The housing shell fragment portion 76 of rear side is applied to the effect of the position that the contact pad of contact site 61c that the effect of the position that downward active force on card 101 contact in the contact site 51c of backside terminals 51 and the contact pad of card 101 is thus greater than at front side terminal 61 and card 101 contacts, and the housing shell fragment portion 76 of front side is applied to downward active force on card 101 at the contact site 61c of front side terminal 61 and and block the contact site 51c that the effect of the position that 101 contact pad contacts is greater than in backside terminals 51 and blocks the effect of the position that 101 contact pad contacts.

The contact site 51c of backside terminals 51 and card 101 contact pad are subject to together thus the active force that the housing shell fragment portion 76 that contacts active force that arm 51b applies and rear side of backside terminals 51 applies and press mutually, thereby maintain reliably the contact between the contact site 51c of backside terminals 51 and the contact pad of the card 101 of corresponding contact site 51c.In addition, the contact site 61c of front side terminal 61 and card 101 contact pad are subject to together the active force that the housing shell fragment portion 76 that contacts active force that arm 61b applies and front side of front side terminal 61 applies and press mutually, thereby maintain reliably the contact between the contact site 61c of front side terminal 61 and the contact pad of the card 101 of corresponding contact site 61c.
