Abstract
The invention relates to a card connector. Specifically, the invention provides a card connector having a detection switch for detecting the insertion and pulling-out of a card. The card connector can perform scraping motion through the vertical movement of contact parts of a contact member forming the detection switch and can shorten the length of a card along an insertion length. When the card is detected by the detection switch detecting card insertion and pulling-out to be inserted, the top end of the card abuts on a cam part of a first contact member. If the insertion of the card continues, the card makes the cam part descend and then resides thereon. A first contact part descends and performs scraping motion on a second contact part. If the insertion of the card goes farther, the top end of the card passes through the upper part of the first contact part and abuts on the second contact part. The second contact part is separated from the first contact part with the further insertion of the card.

First, consider the card insertion space 17 that card 60 does not insert card connector 1, or as shown in FIG. 4 and 5, the tops that card 60 is inserted to these card insertion spaces 17 and card 60 are connected to the state before the cam part 41b of the first contact 41.In this case, the second 42d of contact portion of the second contact 42 flexibly contacts the first 41c of contact portion of the first contact 41, switch closure.Thus, card is not detected as and does not insert.
And in this case, ground contactor 21 not yet contacts the earthy pad 61 arranging at the back side of card 60, in addition, not yet pad 62～66 for activation signal of contact 22～26 for signal.
Then, start to make card 60 along advancing with the card insertion direction shown in arrow X from the state shown in Fig. 4 and Fig. 5.So as shown in Figure 6, the top of card 60 is connected to the cam part 41b of the first contact 40.Then, if card 60 insertion carry out, as shown in Figure 7, card 60 cam part 41b is declined and on take above it.Now, the first 41c of contact portion of the first contact 41 declines and to the second 42d of contact portion of the second contact 42 action of swiping.Then, if card 60 the step that is inserted into carry out, the scraping release of the first 41c of contact portion, and the top of the top of card 60 by the first 41c of contact portion and be connected to the second 42d of contact portion.
And, start to make the step that is inserted into of card 60 to carry out and push until block 60 top being connected to the left wall 16 in the rear end arranging at housing 10 from the state shown in Fig. 7.So, become the card shown in Fig. 8 and Fig. 9 and give as security the state of cutting.Give as security and cut under state at this card, it is mobile that the top of card 60 makes the second 42d of contact portion of the second contact 42 press to the depths thruster of card insertion direction, and the first 41c of contact portion of the second 42d of contact portion and the first contact 41 is spaced apart.Thus, switch disconnects, and the insertion of card 60 detected.
Give as security and cut under state at this card, ground contactor 21 contacts the earthy pad 61 arranging at the back side of card 60, in addition, and signal use contact 22～26 pad 62～66 for activation signal.
In addition, now, as shown in Figure 9, the contact site 41d that forms the first contact 41 of grounding component contacts the earthy pad 61 forming at the back side of card 60.Therefore, the first contact 41 also has concurrently as the function of switch contact with as the function of grounding component, does not need to arrange separately grounding component, can seek minimizing that parts count and the reduction of cost.In addition, even if the earthy pad 61 of predetermined the first contact 41 contact cards 60 also makes the first contact 41 act as grounding component.Therefore, do not have the risk that contacts the short circuit that earthy pad 61 causes because of the first contact 41.
Then, if give as security to cut under state at the card shown in Fig. 9, hand is taken away and discharged from blocking 60, by the effect of ejecting mechanism 50, card 60 is discharged direction along the card with shown in arrow Y and is moved as shown in Figure 10 and Figure 11, becomes card chimerism.
Under this card chimerism, the second 42d of contact portion of the second contact 42 is still connected to the top of card 60, but spaced apart with the first 41c of contact portion of the first contact 41.Therefore, maintain switch off state, maintain the state of the insertion that card detected.
In addition, under this card chimerism, maintain ground contactor 21 and contact the state at the earthy pad 61 of the back side of card 60 setting, in addition, maintain the state of signal contact 22～26 activation signals pad 62～66.
In addition, about the contact site 41d of the first contact 41 that forms grounding component, under card 60 chimerism, as shown in Figure 11 (A), the length that has an earthy pad 61 forming at the back side of card 60 is short and do not contact the situation that this earthy pad 61 contacts.In addition, as shown in Figure 11 (B), the length that also has an earthy pad 61 forming at card 60 the back side is long and the contact site 41d of the first contact 41 contacts the situation of this earthy pad 61.
On the other hand, in the time that card 60 is extracted from card insertion space 17, start temporarily along card insertion direction pushing card 60 from card chimerism.Then,, if hand is taken away from blocking 60, the effect of the spring members 54 by ejecting mechanism 50 is discharged direction to blocking 60 application of forces along card, card 60 can be extracted from card insertion space 17 thus.Take out in process at this card 60, the first contact 41 and the second contact 42 carry out the action contrary with the insertion process of card 60.
,, if start temporarily to block 60 along card insertion direction pushing from the card chimerism shown in Figure 10 and Figure 11, become the card shown in Fig. 8 and Fig. 9 and give as security the state of cutting.Now, it is mobile that the top of card 60 makes the second 42d of contact portion of the second contact 42 press to the depths thruster of card insertion direction, and the second 42d of contact portion is still spaced apart with the first 41c of contact portion of the first contact 41.Thereby, maintain the off-state of switch, maintain the state of the insertion that card detected.
Then, if give as security to cut under state at this card, hand is taken away from blocking 60, the effect of the spring members 54 by ejecting mechanism 50 is discharged direction to blocking 60 application of forces along card, becomes the card discharge state shown in Fig. 5 after through the state shown in Fig. 7 and Fig. 6.
At this, become the state shown in Fig. 7 if cut state from card signature, the second 42d of contact portion of the second contact 42 is connected to the first 41c of contact portion of the first contact 41.Thus, switch becomes closure state, becomes the state not inserting that card detected.Then, if become the state shown in Fig. 6 from the state shown in Fig. 7, block 60 top and leave the second 42d of contact portion of the second contact 42, the cam part 41b of the first contact 41 rises.Thus, the first 41c of contact portion rises and to the second 42d of contact portion action of swiping.Under the card discharge state shown in Fig. 4 and Fig. 5, maintain the contact condition to the first 41c of contact portion of the second 42d of contact portion, maintain the closure state of switch.
So, the card connector 1 related according to present embodiment, in the time of the insertion of card 60, card 60 is connected to the cam part 41b of the first contact 41.Then, if card 60 insertion carry out, block 60 cam part 41b is declined and on take above it, the first 41c of contact portion of the first contact 41 declines and to the second 42d of contact portion of the 2nd contact 42 action of swiping.In addition, in the time of card 60 take out, the contrary action while carrying out with the insertion of card 60 of the first contact 41.Therefore, can be moved along the vertical direction and be carried out scraping action by the first 41c of contact portion of the first contact 41 of sense switch 40, action can obtain fully and swipe reliably between the first and second contact 41,42.
In addition, block 60 the step that is inserted into after moving and carry out, the scraping release of the first 41c of contact portion if decline and the second 42d of contact portion swipe at the first 41c of contact portion.Meanwhile, the top of card 60 top by the first 41c of contact portion and be connected to the second 42d of contact portion.Then, if card 60 the step that is inserted into is carried out, blocking 60 top, that the second 42d of contact portion is pressed to the depths thruster of card insertion direction is mobile, and the second 42d of contact portion and the first 41c of contact portion are spaced apart.Therefore, the state completing in the insertion of card 60, blocks under chimerism, and the first 41c of contact portion of the first contact 41 of the action of swiping is positioned at the downside of card.Therefore, can shorten the card insertion direction length of card connector 1.
In addition, the second 42d of contact portion of the second contact 42 utilizes the flat board extending along the vertical direction to form, and the angle of shear edge of the first 41c of contact portion of the first contact 41 contacts its pressing face.Therefore, situation about contacting with each other with plane is compared, the hertz stress (Hertz Stress) can improve the first 41c of contact portion and contact the second 42d of contact portion time.In addition, the contact can also reduce scraping action time.
Above, embodiments of the present invention have been described, but the present invention is not limited to this, can carries out all changes, improvement.
For example, not necessarily need the angle of shear edge of the first 41c of contact portion of the first contact 41 to contact the pressing face of the second 42d of contact portion.
In addition, the first contact 41 not necessarily need to also have the function as grounding component concurrently outside the function as switch contact.
