Here, slope and the stage 182a～182f of the portion mode of not describing opposite rail with the other end of the locking branch 170 of butt forms.

As shown in Figures 7 and 8, the starting point as the track of heart-shaped cam slot part 180 is that bottom surface 182a is as the plane parallel with the bottom surface of slide block 150.And, form the sloping 182b on the inclined-plane that forms in the mode that erects from bottom surface 182a.

If surpass sloping 182b, then for having the bottom surface 182c on the plane higher than bottom surface 182a as the bottom surface on inclined-plane.If surpass bottom surface 182c then constitute ladder, and constitute the bottom surface 182d of bending with plane lower than bottom surface 182c.

Promptly, the base end part 172 of locking branch 170 moves to the process that fastens the position from the card insert opening side position at slide block 150, when arriving bottom surface 182d, can not turn back to bottom surface 182c.And, if surpass bottom surface 182d then constitute ladder, and the bottom surface 182e on the low plane of constituent ratio bottom surface 182d.

Bottom surface 182e forms V-shaped valley by the inwall of overlooking V word shape that protrudes in the card insert opening side.The base end part 172 of locking branch 170 moves to the process that fastens the position from the card insert opening side position at slide block 150, can not turn back to bottom surface 182d when arriving bottom surface 182e.The state that base end part 172 arrives the bottom surface 182e of V-shaped valley 34 is the lock-out state or the installment state of card 200.Have, base end part 172 is the track in outlet from the track that bottom surface 182a arrives bottom surface 182e again.

And, to block 200 in the reinforcing of opposing helical spring 160 is that rear side is when further inserting to the inboard of connector 100, then the base end part 172 of locking branch 170 discharges from V-shaped valley 34, surpasses the bottom surface 182f that bottom surface 182e is positioned at ladder and has the plane lower than bottom surface 182e.Promptly, the base end part 172 of arrival bottom surface 182f can not turn back to bottom surface 182e.

Having, is bottom surface (slope) 182g to be connected with bottom surface 182f and to form the inclined-plane that favours card insertion one side from the mode that bottom surface 182f erects again.

Insertion oral-lateral at sloping 182g forms the bottom surface 182h with plane higher than sloping 182g.Insertion oral-lateral 102 sides at this bottom surface 182h form ladder, and configuration has the bottom surface 182a on the plane lower than bottom surface 182h.

So form heart-shaped cam slot part 180, so that the contact point of the locking branch 170 that slides is described partly to describe irreversible track in short transverse in the planar obit simulation of heart shape on the bottom surface.

In addition, heart-shaped cam slot part 180 is configured in and leaves the leading section of depositing not the storage card in 104 in and along a side (with the side of card insert opening 102 as main apparent time right side) of connector 100 and between the helical spring 160 that direction of insertion prolongs in connector 100.

Just, in connector 100, on housing 110, deposit and reasonable disposition storage part 104, comprise locking mechanism portion 140 helical spring 160 and the heart-shaped cam slot part 180 of slide block 150 reinforcings.

Thus, in connector 100, the transverse width of this connector 100 forms and is similar to the width dimensions that conforms to the transverse width of the transverse width of storage card self and locking mechanism portion 140, realizes miniaturization, and realizes the saving spatialization of installing space.

Be configured on the base plate 112 of housing 110 of said structure slide block 150 by above the seal cover 120 of top covering shell 110 (with reference to Fig. 1) limit moving of direction up and down.Thus, slide block 150 laterally moving freely on leading section (fan-shaped part) 117a of fore-and-aft direction and slit 117 only.

Push to storage part 104 sides by pawl pressing tablet 128 when particularly, slide block 150 forwards afterburning by helical spring 160 and that be positioned at the position of card insert opening side is pushed downwards by slide block compressing piece 122.

In addition, the slide block 150 crimping slide block compressing pieces 122 that are being positioned at the card insert opening side.Thus, slide block 150 is promptly being blocked occasion that the holding position turns back to the position of card insert opening side when just blocking discharging operation by the last distolateral position of active force in storage part of helical spring 160, slide block compressing piece 122 mainly weakens the locomotivity of the slide block 150 that is obtained by active force with pressing tablet 128.

Card when so, the locking transfer part 155 of pawl pressing tablet 128 and slide block compressing piece 122 and slide block 150 together constitutes card 200 discharges is jumped out anti-locking mechanism.In the present embodiment, pawl pressing tablet 128 utilizes the bending part 129 (with reference to Fig. 1) of storage part 104 sides that protrude in card 200 in the horizontal direction to slide block 150 effect pressing forces, and slide block compressing piece 122 acts on pressing forces in vertical direction to slide block 150.Just, pawl pressing tablet 128 and sliding pressure contact pin 122 with the direction of direction of insertion quadrature on the slide block 150 that moves along direction of insertion is pushed, effectively suppress the locomotivity of direction of insertion.

Secondly, to blocking 200 to as above the loading and unloading action of the memory card connector of formation and the action of locking mechanism portion describe.

Do not inserting in card 200 connectors of card 200, slide block 150 carries out reinforcing by helical spring 160 to connector the place ahead, carries out reinforcing (with reference to Fig. 2) by pawl pressing tablet 128 to storage part 104 sides simultaneously.

Thus, with regard to the slide block 150 that moves that top 121 of base plate 112 and seal cover 120 is limited direction up and down, following guide protrusion portion 151 is pressed against the anterior end of slit 117, and pushes to storage part 104 sides at the leading section 117a of slit 117.Thus, slide block 150 is also being swung with storage part 104 opposite sides with the state that lock pawl 155 protrudes in the storage part 104 in the horizontal direction freely in the position of card insert opening side.In addition, the base end part 172 that is inserted into the locking branch 170 in the heart-shaped cam slot part 180 this moment is configured in the front end side of bottom surface 182a.

To block 200 from card insert opening 102 is inserted in the card connector of this state.So, pushing the end face that is present in the open side of just inserting the locking claw 155 in the zone in the storage part 104 by the end of card 200 in direction of insertion, slide block 150 is certainly in swinging in the horizontal direction with storage part 104 opposite sides.Thus, to the direction displacement of leaving card 200, enter into pawl fastening groove 220 in the side slip of the jut 230 of the side of the card 200 of the card 200 of locking claw 155 in being inserted into storage part 104.Thus, card 200 self is held (with reference to Fig. 1) with half lock-out state that plugs freely.

In addition, at this moment, relatively dispose extension 156 with the notch 210 that blocks 200, notch 210 and extension 156 are in mated condition.

After this, because the active force of opposing helical spring 160 blocks 200 insertions in direction of insertion (A direction), thus slide block 150 so that the state that is engaged in the pawl fastening groove 220 of locking claw 155 be urged at inclined plane 156a by the inclined plane 212 that forms notch 210.Thus, slide block 150 is directed in slit 117, moves to the rear end side of connector 100.At this moment, because the base end part 172 (bending axle) of locking branch 170 is configured in the heart-shaped cam slot part 180, so locking branch 170 is from moving in outlet direction (from bottom surface 182a through sloping 182b, the bottom surface 182c direction to bottom surface 182d) on the bottom surface.

When slide block 150 was inserted into the inboard, then the base end part 172 of locking branch 170 dropped into bottom surface 182d from the bottom surface 182c with ladder.And, stop card 200 push (to the pushing of direction of insertion) time just block 200 and be pushed into when the most inboard, the base end part 172 of locking branch 170 since helical spring active force push back to the card inserting side.At this moment, the base end part 172 of locking branch 170 can not turn back to the bottom surface 182c side that is positioned at than 182 high positions, bottom surface, and to bottom surface 182e side shifting and be stuck in the V-shaped valley 34.Under the base end part of locking branch 170 was engaged in state in the V-shaped valley 34, being limited to pulling away the mobile of direction by helical spring active force of slide block 150 was fixed on the installation site of card 200.Promptly, card 200 is in installment state.

Fig. 9 is illustrated in the vertical view that slide block in the connector that relates to an embodiment of the invention is positioned at the housing of the state on the card installation site.Have again, in Fig. 9, omit helical spring for convenience.

As shown in Figure 9, during slide block 250 was positioned on the installation site, the electrode below the front of the card of being installed 200 contacted with a plurality of contacts (arm extending type contact) 130, can block reading of 200 data.In addition, at this moment, locking claw 155 can not break away from from connector 100 because of vibration waits so block 200 easily owing to enter and be engaged in the pawl fastening groove 220 of card 2002.

On the other hand, the state that unlocks takes out the occasions of card 200 cards, will block 200 and be pressed into to the connector inboard from blocking installment state again.

So, block 200 state having installed, resist helical spring active force and will block 200 and further insert, the base end part (bending axle) of locking branch 170 is discharged from V-shaped valley 34 to direction of insertion.So, the base end part of locking branch 170 can not turn back to bottom surface 182d, move and break away to bottom surface 182f, utilize helical spring active force to move (with reference to Fig. 7 and Fig. 8) in the mode of track of describing to turn back to the outlet of bottom surface 182a by sloping 182g, bottom surface 182h from V-shaped valley 34.

Be accompanied by moving of this locking branch 170, slide block 150 is moved to pulling away direction by the active force of helical spring 160, will push to pulling away direction on the inclined plane 212 of the card 200 of inclined plane 156a butt, and card 200 is moved to pulling away direction.

With regard to this connector, discharging card at 200 o'clock, by with pawl pressing tablet (leaf spring) 128 (with reference to Fig. 1) with pawl fastening groove 220 reinforcings of the locking claw 155 of slide block 150 to card, thereby make the anticreep of card 200.Have again, when the discharge of storage card 200, with finger tip bullet (to direction of insertion pushing) thus when the card of lock-out state unlocks, to card pull away direction (discharge direction) mobile slide block 150 and the impetus of storage card 200 when increasing downwards by pawl pressing tablet 128 (with reference to Fig. 1) with afterburning slide block compressing piece 122 (with reference to Fig. 1) rejection of acceleration of slide block 150 self.Thus owing to can directly not push the storage card 200 of discharging from connector, so can not can leave card 200 self the pushing vestige prevent jumping out of this card 200.And the state that is arranged in the card side position at slide block 150 just blocks 200 half lock-out state, is affectedly bashful and pulls out from the end (base end part) of the outstanding laterally card 200 of card insert opening 102 with finger.Thus, locking claw 155 is followed to the swing of slide block 150 and is carried out displacement, extracts from pawl fastening groove 220, along the outward flange of jut 230 notch 210 side shiftings to card 200.Thus, be disengaged, can extract card 200 self blocking 200 half lock-out state.

Secondly, the wrong reversedly occasion of inserting in card 200 tables that insert in connector 100 is as constituted above described.

The wrong reversedly occasion of inserting card 200 in the table in the connector 100 of Figure 1 and Figure 2 state, in card 200, a sidepiece of formation notch 210, pawl fastening groove 220 and jut 230 is configured in guiding side wall portion 113 sides with side wall portion 114 opposite sides of being furnished with slide block 150.

On the other hand, the other end of the leading section of card 200 (with the left side that forms by the opposite side of notch 210 1 sides) is configured in slide block 150 sides of side wall portion 114 sides.

Thus, will block 200 when being inserted in the housing 110, then the bight of the other side of leading section is connected to the inclined plane 156a that protrudes in the extension 156 that inserts area side and goes up and block.On the other hand, at a sidepiece, though the leading section that forms narrowly than notch 210 width is inserted between the protruding end and guiding side wall portion 113 of lock pawl 155, but near the position of the other side of card 200 leading section and inclined plane 156a butt, jut 230 is connected on card insert opening 102 edge parts.At this moment, in the front more forward, between the leading section of card 200 and guiding side wall portion 113, form the gap than jut 230.Under this state, card 200 can not push slide block 150 and then its straight line is moved in direction of insertion, slides along inclined plane 156a in the other side of card leading section, and card 200 self favours side wall portion 114 sides.

Promptly, wrongly reversedly in table inserted card at 200 o'clock, in housing 110, slide on the inclined plane 156a of the extension 156 of slide block 150 in the other side of the linearity of card leading section.Thus, the leading section of card moves in the mode of stopping up the inner space, and card 200 is tilted by the opening surface that card insert opening 102 forms relatively.

Under this state,, also keeping state to be pushed in the housing 110 with respect to card insert opening 102 (opening surface that is formed by card insert opening 102 at length) tilts so block 200 because card is pushed in press direction.

Just block with regard to 200, the other side side is slided along the inclined plane 156a of extension 156, at external part, by side directed at guiding side wall portion 113, jut 230 its front ends of a lateral side of card leading section invade in the storage part 104 when being connected on the internal face that guides side wall portion 113.Thus, with regard to blocking a sidepiece of 200, utilize the jag (as the inclined plane of the cardinal extremity side that forms notch 210) of jut 230 will guide side wall portion 113 when the side pushes, to slide, block 200 and self be embedded in the connector 100.

Figure 10 is the figure that expression is inserted into the storage card mistake state in the connector that relates to embodiment of the present invention.

As shown in figure 10, when card 200 is embedded in the connector 100, in guiding side wall portion 113, when the jag butt of jut 230 inserts oral-lateral part 113a this part 113a is outwards pushed.

Figure 11 is the enlarged drawing of the card insert opening side part of expression guiding side wall portion in connector shown in Figure 10.As shown in figure 11, set stiffener 191 inserting on the oral-lateral part 113a, form from the internal face side and have resin bed 1136, metal level.

Promptly, with regard to the connector 100 of present embodiment, in housing 110, slide block 150 is configured on the card installation site from card insert opening 102 sides freely movably in side wall portion 114 sides, and the internal face along part 113a on the card insert opening side part 113a of the guiding side wall portion 113 relative with sidewall 114 sets the stiffener 191 that this part 113a is strengthened.

In addition, set the side plate 123 of seal cover 120 in overlapping mode in the outside of guiding side wall portion 113.

So, in connector 110, the guiding side wall portion 113 of integrally formed housing 110 and stiffener 191.Thus, with regard to connector 110,, bear card 200 for three layers with the side plate 123 (metallic plate) that guides side wall portion 113, stiffener 191 and seal cover 120 at sidewall sections.

Thus, with regard to connector 100, wrong reversedly the insertion blocked 200 o'clock on the surface, and at the sidewall sections of connector body, the part 113a of butt jut 230 is in the state of strengthening with stiffener 191, can prevent the distortion of connector self.

In addition, by connected entrance 193 outstanding being provided with of stiffener 191 claw 1135 (with reference to Fig. 5) is installed in the outside of card side part 113a with the resin system of housing 110 one.Thus, in the outside of guiding side wall portion 113, in the end (leading section) of the card insert opening side of each and side wall portion 114 of end of card insert opening side (leading section) and base end part and each of base end part form claw 1135 be installed.

This installation claw 1135 forms by flowing out resin laterally from the inboard of stiffener 191 when contact 130 is especially inserted shaping as the product of insertion to housing 110 with the metallic plate of stiffener 191.Claw 1135 is installed is cooperated, thereby seal cover 120 stably can be installed on the housing 110 with the fastening hole 126 (with reference to Fig. 5) of seal casinghousing.

In addition, form protuberance 192 (with reference to Fig. 5) accordingly in the part of inner face side and butt card 200, on the side plate 123 of these protuberance 192 contacts at seal cover 120 in the outside of the stiffener 191 that forms a part that guides side wall portion 113 outsides.Because stiffener 191 will be delivered to the side plate 123 of seal cover 120 because of the load that mistake is inserted the card 200 that is subjected to.

In addition, stiffener 191 self is as shown in Figure 2 in connector body, restriction is deposited in the base plate 112 of bottom surface portions of storage part 104 of card, and extends and the reinforcement base plate 310 usefulness same parts that are provided between guiding side wall portion 113 and the side wall portion 114 form at Width.

Because, even since the wrong card 200 that comes that injects make and press stiffener 191 from storage part 104 thrusters, load can be distributed to below on the reinforcement base plate 310 relative with card 200, much less stiffener 191 is strengthened base plate 310 and also is in the state that bears card 200.

Thus, can further improve the intensity of guiding side wall portion 113.In the present embodiment, in the insertion oral-lateral part 113a of guiding side wall portion 113, compare, can realize that about 2.6 times intensity improves with the structure that does not have stiffener 191.
