Description

Connecting device for card

Technical field

The present invention relates to a kind of connecting device for card that card with information storage function can be installed, particularly relate to the improvement of its trip mechanism.

Background technology

As the trip mechanism that is installed on this kind connecting device for card, known in the past structure is: when direction of insertion was pressed into, this card can be discharged (for example, referring to Patent Document 1) by the elastic force of built-in spring with the card under the installment state.This trip mechanism in the past generally has: the card that is inserted into the card resettlement section with card insert opening from housing fasten and can be to the direction of insertion of this card and discharge slide block that direction move, to card discharge direction to the spring members of this slide block application of force, heart type cam path, and move the sliding pin of (slip) along this heart type cam path, by the sliding pin card is ended on the sticking department of heart type cam path, slide block is locked on the preposition.

Promptly, in this prior art, the card that will have an information storage function is fashionable to card resettlement section interpolation from the card insert opening of housing, and the slide block that is pressed into the front end of card overcomes power that spring members applies to the device medial movement, be accompanied by moving of this slide block, sliding pin slides along heart type cam path.And, by will block in the card resettlement section, insert a certain amount of, the sliding pin card is ended on the sticking department of heart type cam path, therefore slide block is locked, thereby being reached, card is maintained at the state of being scheduled on the installation site, under this state, the terminal component in the termination contact portion of card and the housing contacts.In addition, when discharging the card of installing, be pressed into a little by the card that will remain on the installation site to direction of insertion (device is inboard), sliding pin is broken away from from the sticking department of heart type cam path, thus, slide block is unlocked, thereby spring members is to this slide block application of force.Therefore, if remove the operating physical force that is pressed into card, on one side card is pressed on one side by the slide block of the spring members application of force and moves, thereby can make this card be discharged to predetermined drain position to discharging direction (device front side).

Patent documentation 1: TOHKEMY 2000-251025 communique (the 3-4 page or leaf, Fig. 2)

In above-mentioned prior art, because the structure of trip mechanism can be oversimplified, thereby realize the miniaturization and the cost degradation of connecting device for card easily, if it is but strong excessively to the elastic force-applying of the spring members of the slide block application of force to card discharge direction, slide block fast moving when then worrying the card discharge, card flies out from card insert opening and comes off.Therefore, thereby consideration is set at more weak the flying out of card that prevent with the elastic force-applying of spring members, but, the contact pressure that is used for guaranteeing the reliability that is connected between the terminal component of the termination contact portion that blocks and jockey under installment state is essential, because when card is discharged, spring members must apply the power that exceeds this contact pressure to slide block, therefore, if worry power that spring members applies cross a little less than card can not discharge.In addition, also can consider by be provided with on the capping of the upper cover part of housing from above to the flexure strip of the card application of force, thereby the interior card of jockey is become to be difficult to move, but in this case, if thereby spring members does not overcome very big power behind the elastic force-applying of additional this flexure strip on the described contact pressure to the slide block application of force, then can not discharge by card, therefore, the result is, is set at stronger needs though produced the power that spring members is applied, and reduced the effect that prevents that card from flying out.

Summary of the invention

The present invention finishes in view of the actual conditions of described prior art, and its purpose is to provide a kind of connecting device for card, and it can prevent flying out of card under the situation of miniaturization and cost degradation.

For achieving the above object, connecting device for card of the present invention, it has: slide block fastens with the card that inserts in the card resettlement section from the card insert opening of housing, and can and discharge on the direction and move in the direction of insertion of this card; Force application part is used for discharge direction to this card to this slide block application of force; Cam mechanism has the slide unit that moves along cam path, and described slide block can be locked on the precalculated position; Terminal component, when this cam mechanism locks described slide block and makes described card be in installment state, contact with the termination contact portion of this card, remove the described locking of described slide block by be in described card under the installment state to the direction of insertion pressing operation, described force application part should block to discharging direction by this slide block to be released, and be provided with swing mechanism, described swing mechanism is used in the described locking of removing described slide block and after described termination contact portion leaves from described terminal component, make this slide block can be to described card resettlement section one side shifting, by this swing mechanism to described card resettlement section one side by this slide block of the application of force with described card by inwall to described housing.

In the connecting device for card that constitutes like this, when card is discharged, apply and make the slide block can be, thereby therefore the card in will moving, be discharged from thereby this inwall limit of card sliding contact is subjected to the resistance to sliding limit by on the inwall of housing to the power of card resettlement section one side shifting.But, because till the termination contact portion of card is left from described terminal component, can not apply and make the slide block can be to the power of card resettlement section one side shifting, the power that therefore will described force application part apply is set by force excessively.And because the inwall of card sliding contact housing moves to discharging direction thereby the limit is subjected to suitable braking limit, even therefore the power that applies of described force application part is strong, card can not fly out from card insert opening yet.

In the connecting device for card that constitutes like this, have: the outstanding guiding projection that is arranged on the described slide block; First gathering sill, it is opened on the described housing, and engages described guiding projection, is used for guiding this guiding projection to the direction of insertion and the discharge direction of described card; Second gathering sill, be opened on the position that is communicated with described first gathering sill of described housing, and allow that described guiding projection is to described card resettlement section one side shifting, when making described guiding projection be positioned at described second gathering sill, described slide block by described force application part to described card resettlement section one side by the application of force.Thus, can constitute described swing mechanism by described second gathering sill, described guiding projection and described force application part, therefore need not to append new parts can prevent flying out of card by simple structure.

In addition, in this case, if described guiding projection is to be made of a pair of described guiding projection that separates configuration on described slide block along its length, and, described first gathering sill is to be made of a pair of described first gathering sill that engages with described each guiding projection respectively, and, clipped by this a pair of first gathering sill, and with position that first gathering sill away from the inboard of described card insert opening is communicated with on, offer described second gathering sill, then, as the swing fulcrum, be easy to make another direction protrusion portion that is positioned at second gathering sill the direction protrusion portion in inserting mouthful first gathering sill of a nearest side of being fastened on to blocking resettlement section one side oscillation.Therefore, the end of the inboard by slide block can be pushed the card when discharging reliably from the side, need not to worry therefore that blocking is moving insufficient, can realize the raising of reliability.

In addition, in this case, if the described cam path of described cam mechanism is arranged on described slide block and the face side opposition side with described guiding projection, then compare with the structure that this cam path is arranged on the housing, duty factor significantly improves, so can promote the miniaturization of jockey.

In addition, in this case,, then can allow the swing of described slide block to the card resettlement section, the braking that blocks reliably if described second gathering sill is more side-prominent and form wide cut to described card resettlement section one than described first gathering sill.

In addition, in this case, if described first gathering sill is connected with described second gathering sill, so that after described terminal component leaves in described termination contact portion, described guiding projection moves to described second gathering sill, then after terminal component left in the termination contact portion of card, need not to append new parts can make slide unit to resettlement section one side oscillation by simple structure.

Connecting device for card of the present invention, at the lock-out state of removing slide block, thereby after making the terminal component of termination contact portion separating device of card, apply the power of this slide block that makes by swing mechanism to the card resettlement section lopsidedness of device, thus, card when discharging is by on the inwall of housing, and therefore, cartoon is crossed this inwall limit and is subjected to suitable braking limit and moves to discharging direction.Therefore, even it is strong to the power that the force application part of the slide block application of force applies to discharge direction to card, card when also need not to worry to discharge flies out from the card insert opening of device, in addition, described swing mechanism can not append new parts and constitute simply, therefore need not to worry to have the miniaturization and the cost degradation of damage device.

Fig. 1～connecting device for card shown in Figure 3, roughly the box-shaped shell 3 that forms by on frame 2 not shown clamshell being set, the output mechanism 5 arranging a plurality of terminal components 4 of the inside be arranged on housing 3 and be installed in a side of housing 3 constitute.Housing 3 is provided with: card insert opening 3a is used to have the insertion and the discharge of the card 1 of information storage function; Card resettlement section 3b, it is communicated with space outerpace by card insert opening 3a in the space that is covered by described clamshell.Output mechanism 5 has: slide block 6 engages with the card 1 that inserts in card resettlement section 3b from card insert opening 3a, and can go up mobile in this direction of insertion and discharge direction (left and right directions of Fig. 1～Fig. 3) of blocking 1; Helical spring 7 is discharged direction (right of Fig. 1～Fig. 3) to slide block 6 application of forces to card; Sliding pin 9 is fastened in the heart type cam path 8 that is arranged on slide block 6 upper surfaces one end thereof (slip end) 9a; Another end 9b of sliding pin 9 can be supported by frame 2 with freely swinging.Thus, slip end 9a is accompanied by moving of slide block 6 and moves (slips) along heart type cam path 8, and when slip end 9a was fastened on the sticking department 8a (with reference to figure 4) of heart type cam path 8, slide block 6 was locked on the precalculated position.In addition, as shown in Figure 4, heart type cam path 8 has past road 8b, returns road 8c and comes and goes dual-purpose path 8d, forms sticking department 8a toward road 8b with the coupling part of returning road 8c.In addition, as shown in Figure 1, 2, be provided with the 1a of termination contact portion that contacts with terminal component 4 when mounted in the inboard of card 1 front end.

The laterally projecting engaging arm 10 that is provided with on the end of slide block 6 inboards, this engaging arm 10 is configured in the 3b of card resettlement section and with the front end of card 1 and engages.In addition, on the bottom surface of slide block 6, outstanding a pair of guiding projection 6a, the 6b of arranged spaced in the longitudinal direction of being provided with.These guiding

projections

6a, 6b penetrate in the first gathering sill 2a, the 2b or the second gathering sill 2c that offers on the frame 2.That is, offer in the lower zone of the slide block 6 on frame 2: the first gathering sill 2a of slit shape from extending to the inside near the card insert opening 3a, and engages with a guiding projection 6a; The second gathering sill 2c of long hole shape reserves predetermined space in the inboard of the described first gathering sill 2a and is set up, and is through with another guiding projection 6b; The first gathering sill 2b of slit shape is set to be communicated with the inboard of the described second gathering sill 2c, and engages with another guiding projection 6b.When slide block 6 to card 1 direction of insertion with discharge direction when moving, a guiding projection 6a is always spacing by the first gathering sill 2a, but another guiding projection 6b is just limited only in the first gathering sill 2b time, can swing in the time of in the second gathering sill 2c.Promptly, compare with the

first gathering sill

2a, 2b, the second gathering sill 2c is the bigger excision of quilt on Width, thereby the slit between itself and the resettlement section 3b narrows down, therefore, when the elastic force-applying of another guiding projection 6b by helical spring 7 in the first gathering sill 2b in the second gathering sill 2c when mobile, thereby this another guiding projection 6b is swung by the application of force to card resettlement section 3b, thus, apply make slide block 6 with another guiding projection 6b in the first gathering sill 2a as the power of fulcrum to card resettlement section 3b lopsidedness.

In the connecting device for card that constitutes like this, at first, the action that just will block when inserting and installing describes.Fig. 2 (a) and Fig. 3 (a) expression card 1 insert in card resettlement section 3b from card insert opening 3a, and should card 1 front end with slide block 6 engage arm 10 state of contact, at this moment, the slip end 9a of sliding pin 9 be positioned at heart type cam path 8 round dual-purpose road 8d in portion.From this state, if will blocking 1, the operator in card resettlement section 3b, is pressed into, then block 1 front end and be pressed into engaging arm 10, therefore thereby slide block 6 overcomes the elastic force-applying of helical spring 7 to device medial movement (with reference to figure 2 (b)), be accompanied by moving of this slide block 6, slip end 9a moves (with reference to figure 3 (b)) from the round dual-purpose road 8d yearning road 8b of heart type cam path 8.And, when will blocking 1, the operator further is pressed into and when making slip end 9a arrive forefront toward road 8b, being moved further of slide block 6 by sliding pin 9 restrictions, if but remove the operating physical force that is pressed into herein, slide block 6 can return a little to the device front side under the effect of the elastic force-applying of helical spring 7, thereby slip end 9a card is ended sticking department 8a place at heart type cam path 8, therefore, slide block 6 is lockable, thereby be in card 1 is remained on the state of being scheduled on the installation site (with reference to figure 2 (c) and Fig. 3 (c)).Under this state,, so can carry out the transmitting-receiving of the signal of telecommunication because card 1 the 1a of termination contact portion contacts with terminal component 4 in the housing 3.

In addition, in will blocking 1 process of in card resettlement section 3b, inserting and installing like this, shown in Fig. 2 (a)～(c), a 6a of direction protrusion portion of slide block 6 in the first gathering sill 2a to the device medial movement, and the 6b of another direction protrusion portion moves in the first gathering sill 2b in the second gathering sill 2c, the function that the

first gathering sill

2a, 2b realization is moved slide block 6 straight lines.

Below, action when just making card 1 discharge under the installment state that is in shown in Fig. 2 (c) describes, then the operator is by being pressed into a little with this card 1 to device inboard (card insertion direction), thus, can make the sticking department 8a disengaging of the slip end 9a of sliding pin 9 from heart type cam path 8, thus, the slide block after the release 6 is by helical spring 7 elastic force-applyings.Therefore, if remove the operating physical force that is pressed into card 1, then pushed card 1 by engaging arm 10 on one side by the slide block 6 of helical spring 7 elastic force-applyings, to device front side (card discharge direction) move on one side, at this moment, the slip end 9a that breaks away from from sticking department 8a moves to round dual-purpose road 8d from past road 8c.Yet, when the elastic force-applying of the 6b of another direction protrusion portion by helical spring 7 in the first gathering sill 2b in the second gathering sill 2c when mobile, then as mentioned above, the 6b of another direction protrusion portion is to card resettlement section 3b swing, make the power of slide block 6 thereby apply, pass through slide block 6 quilts by on the inwall 2d of frame 2 (with reference to figure 1 (a) and (b)) so block 1 to card resettlement section 3b lopsidedness.Therefore, block 1 sliding contact this inwall 2d and when being subjected to resistance to sliding, move to discharging direction.That is, card 1 continues to be subjected to the braking of this inwall 2d, and by engaging arm 10 on one side by helical spring 7 elastic force-applyings, Yi Bian be discharged from, even therefore the elastic force-applying of helical spring 7 is very strong, card 1 can not fly out from card insert opening 3a yet.

Like this, card 1 moves to preposition when being subjected to suitable braking, when the operator should block 1 when extracting from jockey, owing to be removed from the reaction force of card 1, so slide block 6 is in the posture (with reference to figure 1 (c)) to the big slightly inclination of card resettlement section 3b one side.And, if insert in the 3b of resettlement section to card from card insert opening 3a will blocking 1 under this state once more, thereby will block 1 front end is pressed on the engaging arm 10, then shown in Fig. 2 (a), posture before slide block 6 quilts are pushed back, slide block 6 direction of insertion and the discharge direction with card 1 on its length direction is approximately consistent.

In addition, when carrying out such discharging operation, because till the 1a of termination contact portion of card 1 leaves from terminal component 4, the 6b of another direction protrusion portion is positioned at the first gathering sill 2b, so can not apply the power of slide block 6 that do not make to card resettlement section 3b lopsidedness, therefore block 1 and inwall 2d between resistance to sliding little.Therefore, thus the elastic force-applying of helical spring 7 preferably can overcome the degree that contact pressure between 1a of termination contact portion and the terminal component 4 makes slide block 6 side shifting before device, will not set by force excessively by this elastic force-applying.Promptly, if the elastic force-applying of helical spring 7 is strong excessively, even the card in the time of will discharging 1 is by on the inwall 2d of frame 2, this card 1 is flown out from card insert opening 3a, but in the present embodiment, because the elastic force-applying of helical spring 7 needn't be set very by force, therefore can prevent flying out of card 1 reliably.

Simultaneously, in the present embodiment, when the discharging operation that blocks 1, as long as the 6b of another direction protrusion portion is imported in the second gathering sill 2c in the first gathering sill 2b, will apply and make the power of slide block 6 to card resettlement section 3b lopsidedness, therefore not appending new parts can prevent that card 1 from flying out by simple structure.In addition, this moment be fastened in the first gathering sill 2a a 6a of direction protrusion portion as the swing fulcrum, the 6b of another direction protrusion portion that is positioned at the second gathering sill 2c is easily to card resettlement section 3b one side oscillation, card 1 when the end of inboard (helical spring 7 one sides) that therefore can be by slide block 6 is pushed discharge reliably from the side, therefore need not to worry that card 1 braking is insufficient, reliability improves.

In addition, in the present embodiment, because heart type cam path 8 is arranged on the side opposite with the side of the 6a of direction protrusion portion, 6b with slide block 6, therefore compare with the structure that heart type cam path 8 is arranged on the housing 3, can increase substantially duty factor, therefore promote the miniaturization of jockey.But even heart type cam path 8 is arranged under the situation of the structure on the housing 3, the application of the invention also can prevent flying out of card 1.
