Promptly, the slide block 150 that is positioned at half latched position makes locking claw 155 under the outstanding state in accommodation section 104, become the pressing force that overcomes pawl pressing tablet 128 and swing the state that freely disposes.Therefore, as shown in Figure 1, be positioned at slide block 150 under the state of half latched position, insert accommodation section 104 if will block 200, then the jag of the locking claw 155 of strain cooperates with the cooperating recesses 220 of card 200 freely to cooperate or freely to remove the mode that cooperates, and can plug maintenance freely (half locking) card 200.
In the card connector 100 that constitutes like this, in order to assemble or half locking card 200 and at movable part, on helical spring 160, apply lubricant here.
Lubricant is semisolid lubricants (lubricating grease) preferably, is applied to the moving part that the sliding part that comprises helical spring 160 grades.Decay the thus active force of helical spring 160 reduces by the active force of helical spring 160 to the translational speed of discharging the mobile slide block 150 of direction (B direction shown in Figure 1).Specifically, in the telescopic spring zone, apply lubricant at the whole face of the helical spring 160 of extended configuration.
Lubricant has when because of viscosity the card that flicks (to direction of insertion) lock-out state at card 200 At time of eject, with finger tip being unlocked, because the viscosity that the active force of helical spring 160 reduces to the force of mobile slide block 150 of card pull-off direction (discharge direction) and card 200.Thus, can not stay and push vestige and can prevent flying out of this card 200 on surface from connector card 200.Also have, lubricant also can be applied to the following position of sliding of the following and slide block 150 of slide block 150 on base plate 112.The translational speed of slide block 150 self can be reduced thus, flying out of card 200 can be prevented more effectively.
If card 200 is inserted into card connector 100, then with regard to the slide block 150 of half latched position, locking claw 155 is in the side slip of card 200, thereby enters cooperating recesses 220 and cooperate with cooperating recesses 220 from blocking 200 jut 230.Thus, card 200 self keeps being maintained at locking claw 155 (with reference to Fig. 1) with plug half lock state freely.
Block under 200 the state having assembled like this, insert to direction of insertion again, blocked then that 200 slide blocks of pushing 150 overcome helical spring active force and side shifting inwards if further will block 200.Thus, the base end part 172 (bending axle) of following the stop pin 170 that slide block 150 moves breaks away from from V-shaped valley 34, describes the backhaul track by the active force of helical spring 160, and slide block 150 moves to the pull-off direction by the active force of helical spring 160.Thus, slide block 150 usefulness bearing surfaces will block 200 jut 230 to be pushed to the pull-off direction, and with locking claw 155 side of cooperating recesses 220 is pushed to the pull-off direction, and card 200 self moves to the pull-off direction.
Like this, the active force of slide block 150 by helical spring 160 put and moved to half latched position from clamping coordination, but this moment, its translational acceleration is suppressing mobile for lubricated dose.
In addition,, just resist the power of pull-off direction, so the mobile acceleration of pull-off direction is further suppressed (with reference to Fig. 1) owing on slide block 150, apply by the pressing force of pawl pressing tablet 128 to card 200 sides.Like this, in card connector 100, the locomotivity decay of the slide block 150 when pawl pressing tablet 128 makes the active force of the helical spring 160 of having decayed by lubricant and slide block 150 put the locomotivity of the occasion of returning half latched position and just block discharging operation from clamping coordination.
In this card connector 100, the assembling action by repeating card 200 and block 200 discharging operation, slide block 150 is in half latched position and clamp coordination and move between putting, and follows this to move, and helical spring 160 stretches.Follow the flexible of helical spring 160, be coated in the stretching region that lubricant on the helical spring 160 spreads to helical spring 160, come in and gone out and pushes in the slide block 150 of this stretching region.Thus, lubricant is pushed out into the top plate portion 121 that covers stretching region and attached to this top plate portion 121.
Here, in the base plate 112 of housing 110, at the position that slide block 150 slides, part (stretching region of helical spring 160) that helical spring 160 stretches and the part that constitutes accommodation section 104 are cut apart by slit 117 (with reference to Fig. 4 and Fig. 5).
Therefore, lubricant is stretched and attached on below the slide block 150 from the stretching region of helical spring 160, by capillarity can from the slipper of slide block 150 (below) stretch to accommodation section 104 sides, but separated by slit 117.Thus, lubricant can't arrive accommodation section 104.Specifically, as shown in Figure 5, can not stretch from flexible part (stretching region of helical spring 160) side direction accommodation section 104 sides of helical spring 160 (direction of representing with arrow C).
Fig. 9 is that moving of slide block passed through in expression, attached to the figure that stretches of the lubricant F on the top plate portion 121.Also have, same with direction and Fig. 1 that arrow A, B represent, arrow A is represented card insertion direction, and arrow B is represented card discharge direction.
As shown in Figure 9, on the slider body 152 of slide block 150, slide block 150 is accompanied by moving of slide block 150 in the stretching region of helical spring 160 attached to the lubricant on the top plate portion 121, shown in arrow F1 like that attached on the slide block 150.And lubricant flows in the grooving portion 154 (reference arrow F2), is separated and is directed into grooving portion 154 by divider wall parts 157, and be stored in the grooving portion 154.
Therefore, attached to even the lubricant slide block 150 on the top plate portion 121 moves in this position above attached to slide block 150, can between top plate portion 121 and the slide block 150 that moves capillarity not take place, therefore can not expand, but the direction to arrow F4 is expanded in grooving portion 154 to the direction of arrow F3.
Therefore, lubricant is stretched to accommodation section 104 sides between can be above top plate portion 121 and slide block 150.
Like this, even repeat card 200 is inserted in the accommodation section 104 of card connector 100, maybe will be assemblied in the action that the cards 200 in the accommodation section 104 are discharged from the accommodation section, lubricant can be attached on the card 200 that is plugged yet.
In addition, top plate portion 121 is split into the stretching region side and accommodation section 104 sides of helical spring 160 at the moving area of slide block 150 by otch 122a when overlooking.Therefore, though lubricant from helical spring 160 sides attached to top plate portion 121, also can prevent to expand to accommodation section 104 sides.
