[Problems to be solved by the invention]
However, the erroneous insertion prevention means described in the above-mentioned prior example includes a card which is damaged by a stopper or a free end of a stopper plate when an excessive pushing force is applied to the card, or in some cases cantilever. The stopper or the stopper plate may buckle and bite between the plate surface of the card and the housing, so that the card cannot be ejected. Such a risk is remarkable in a miniature card connector whose miniaturization is promoted in accordance with miniaturization of the card.
[0005]
Therefore, when the card is erroneously inserted in the upside down position, it is possible to mechanically prevent the card from being inserted to the card setting position, and furthermore, an excessive pressing force is applied to the card. Even at this time, there is a demand for a means for preventing such erroneous insertion and, consequently, for preventing the card connector from being destroyed.
[0006]
The present invention has been made in view of the above circumstances, and takes measures to disperse and receive a load generated by locking an end face of a card that is incorrectly inserted in an upside down position at a plurality of locations. This prevents mechanical insertion of the card by mechanical means.In addition, even if an excessive force is applied to the card, the card connector can be easily damaged and the card connector can be easily inserted. Its purpose is to prevent it from being destroyed.
[0007]
Further, the present invention provides a card connector which can prevent the above-described erroneous insertion of a card without causing damage to components, even if there is a variation in dimensions of a card, a contact installation position, etc. within a tolerance range. An object of the present invention is to provide a card connector in which contacts are reliably electrically connected to electrodes of a card inserted in a normal posture at a card set position in a space.
[0008]
[Means for Solving the Problems]
A card connector according to the present invention has a body provided with a card supporting surface on which cards overlap and a cover made of sheet metal attached to the body, and a space between the body and the cover is formed as a card insertion space. The card inserted into the card insertion position of the card insertion space has a contact which resiliently contacts an electrode provided on a plate surface of the card, and a card insertion direction in which the card is erroneously inserted in the card insertion space upside down. A card connector provided with locking means for locking the leading end face of the card so as to prevent the card from being inserted into the set position, by elastically contacting the card inserted into the card insertion space and holding the card in the card supporting surface of the body. And the locking means is cut and raised inward at a plurality of locations on the cover and inserted incorrectly in an upside-down posture. Consisting in engaging piece arrays for locking the said leading end face of the card in surface contact with the plurality of locations, is that.
[0009]
According to the present invention, when a card is erroneously inserted into the card insertion space in an upside down posture, the locking means locks the leading end face of the card and prevents the card from being inserted into the card setting position. Since the locking means is a row of locking pieces for locking the leading end face of the card that has been incorrectly inserted in the upside-down position by surface-contacting the plurality of locations, the locking piece row is inserted into the plurality of locations of the cover. Even if the card is cut and raised in the direction, the load generated by locking the leading end face of the card can be distributed and received at a plurality of locations. Therefore, even if an excessive pushing force is applied to the card, the locking piece row does not buckle, and the locking piece row does not bite between the card and the housing so that the card cannot be ejected. . Further, since the locking piece row locks the leading end face of the card by surface contact, the card is unlikely to be damaged. Furthermore, since the card is provided with a card resilient means for elastically contacting the card inserted into the card insertion space and pressing the card against the card supporting surface of the body, the initial position of the contact and the like can be determined using the card supporting surface as a reference surface. By doing so, even if there are dimensional variations within the tolerance range of the card and the contact installation position, etc., the contacts will be sure to the electrodes of the card inserted in the card insertion position in the card insertion space in the normal posture. As a result, the reliability of the card insertion operation and the reliability of the electrical connection are improved.
[0010]
In the present invention, the plurality of first locking pieces are formed by bending one of the root portions of the cut pieces cut out at a plurality of locations of the cover, and cutting the cut pieces inward. And a second locking piece that is backed up from the back side by a gate-shaped enclosure formed by cutting and raising the cover. According to this, the plurality of first locking pieces can be easily formed, and even if an excessive pressing force is applied to the erroneously inserted card, the pressing force applied to the second locking pieces is changed to a gate-like shape. Since the enclosure portion receives the second locking piece, the second locking piece does not buckle, which also helps to prevent the first locking piece from buckling. Therefore, an excellent erroneous insertion prevention action is exhibited as a whole, and when a card is erroneously inserted in an upside down posture, the card is reliably mechanically prevented from being inserted to the card set position. In addition, even when an excessive pushing force is applied to the card, the locking piece row and the card connector are not broken.
[0011]
In the present invention, the first locking piece is inserted into the card setting position in the card insertion space in a normal posture, and one side plate surface is formed on the other side plate surface of the card overlapping with the card support surface. It is preferable that the protrusion protrudes into the groove-shaped recess, and is arranged in the groove-shaped recess so as to face an electrode forming a step with the other side plate surface of the card at an interval. With this configuration, the first locking piece formed by cutting and raising the cover on the electrode of the card inserted in the normal posture does not short-circuit, and when the card is inserted in the inverted posture, The first locking piece securely locks the leading end face of the card, so that the first locking piece surely exerts the function of preventing the incorrectly inserted card from being inserted into the card setting position in the upside down position. Become.
[0012]
In the present invention, it is preferable that the second locking piece and the surrounding structure are accommodated in a groove provided in a card inserted in a normal posture at a card setting position in a card insertion space. According to this, the card inserted in the normal posture is pushed into the card setting position without being locked by the second locking piece or the surrounding structure.
[0013]
In the present invention, it is desirable that the surface of the first locking piece is subjected to an electrical insulation treatment. According to this, even if metal dust or the like is interposed between the electrode of the card inserted in the normal posture and the first locking piece, the electrode of the card and the first locking piece are interposed via the metal scrap. No short circuit occurs and the electrical connection reliability is improved.
In the present invention, it is desirable that the surface of the second locking piece is roughened to increase the frictional resistance with the leading end face of the card. According to this, when the second locking piece or the first locking piece is locked to the leading end face of the card that has been erroneously inserted in the upside-down posture and the erroneous insertion is prevented, the second locking piece and the card are prevented from being inserted. Contact with the leading end surface of the lock member in a non-slip state, so that an unexpected situation such as the card being lifted and climbing over the first lock member is less likely to occur, and the reliability of the erroneous insertion prevention action by the lock member row is reduced. improves.
[0014]
In the present invention, it is preferable that the card resilient means is a cantilevered leaf spring piece formed by cutting and raising inward on the cover. According to this, the card rejection means can be formed at low cost without adding a component.
[0015]
In the present invention, the card insertion slot of the card insertion space is formed by each edge of the body and the cover, and the edge of the cover forming the edge of the card insertion slot faces outward. It is desirable that it is formed as an invitation piece cut and raised. According to this, it becomes easy to insert the card into the card insertion space through the card insertion slot. This function is extremely useful when the present invention is applied to a micro card connector having an opening width of a card insertion slot of several mm.
[0016]

It is being regulated.
[0019]
A housing is formed by attaching the cover 3 of FIG. 2 to the body 1, and a card insertion space (throttle) is formed by the housing, and the slider 6 is provided inside the housing at a side of the card insertion space. Is located. When the card 100 is inserted into the card insertion space of the housing in a normal posture, the front end corner of the card 100 abuts against the card receiving portion 61 of the slider 6 and pushes the slider 6, and the card 100 is inserted into the card 100 as shown in FIG. The protrusion 63 of the resin lever 63 provided on the slider 6 fits into the recess 120 provided, and the card 100 is half-locked to the slider 6. The slider 6 pushed by the card 100 is locked by the action of the cam mechanism 7 at a position corresponding to the card setting position in the card insertion space. Further, when the slider 6 is locked at a position corresponding to the card setting position, when the slider 6 is pushed through the card, the locked state is released, and the slider 6 is moved together with the card 100 by the force of the spring member 62 to the initial position. Retreat until. The half lock means that the card 100 is pulled out from the slider 6 when the card 100 is pulled with a large force, and when the card 100 is not pulled so much, the card 100 is held by the slider 6. That is.
[0020]
The bottom surface of the body 1 shown in FIG. 1 is formed flat as a card supporting surface 16 on which the card 100 inserted into the card insertion space overlaps. The cover 3 in FIG. 2 is made of sheet metal, and has, on both sides in the width direction, wall portions 31 and 32 that are fitted and fixed to the outside of the side wall portions 13 and 14 of the body 1 in FIG. ing. Further, the cover 3 has card resilient means consisting of front cantilevered leaf spring pieces 34, 34 formed by cutting and raising inward at two places on the left and right sides of the upper plate part 33. The locking piece row 35 is provided on the side part. The locking piece row 35 is composed of a plurality of first locking pieces 36 arranged in a horizontal row and a second locking piece 37 arranged in a row beside the first locking pieces 36. Then, the first locking piece 36 is formed by bending a portion 36a (see FIG. 6) of a base portion of each of the cut pieces cut out at a plurality of locations of the upper plate portion 33 of the cover 3 at a substantially right angle, and joining the cut pieces. It is formed by cutting and raising inward, and the height of each first locking piece 36 is the same. On the other hand, the second locking piece 37 is integrally connected to a gate-shaped enclosure 38 formed by cutting and raising the upper plate 33 of the cover 3. The stopper 37 is backed up from the back side. FIG. 9 is an enlarged cross-sectional view of a portion along the line IX-IX in FIG. 2. As can be seen from FIG. 9, the surrounding portion 38 is formed in a U-shape. The height of the second locking piece 37 and the surrounding structure 38 is such that they do not interfere with the groove 104 provided in the card 100 (see FIG. 3: the groove 104 will be described later).
[0021]
Next, the card 100 to be used shown in FIG. 3 has a flat one side plate surface 101 (see FIG. 6 and the like) and the other side plate surface 102 on the opposite side. At the front end of the other side plate surface 102, a plurality of grooved recesses 103 are provided side by side, and the electrode 110 is separately provided in each of the grooved recesses 103. Have been. In addition, a constant step A is formed between the electrode 110 provided in each groove-shaped recess 103 and the other side plate surface 102 of the card 100. Further, a groove 104 is formed at the front end of one side plate surface 102 of the card 100 at one end in the width direction.
[0022]
FIG. 4 is an enlarged vertical sectional side view of an essential part for explaining an operation when the card 100 is erroneously inserted into the card insertion space in an inverted posture, FIG. 5 is a schematic bottom view for explaining the operation, and FIG. FIG. 7 is an enlarged longitudinal sectional side view of an essential part for explaining an operation when the card 100 is inserted in a normal posture into the insertion space. FIG. 7 is an enlarged essential part for explaining an operation of a leaf spring piece 34 as a card resilient means. It is a vertical side view.
[0023]
When the card 100 of FIG. 3 is inserted in a normal posture into the card insertion position of the card insertion space formed by the space of the mutual rod between the body 1 and the cover 3, as shown in FIG. One side plate surface 101 of the card 100 is resiliently contacted with the other side plate surface 102 of the card 100 and pressed against the card support surface 16 of the body 1 to be in a state of being overlapped in a contact state. Also, as shown in FIG. 6, each of the first locking pieces 36 respectively protrudes into a plurality of groove-shaped recesses 103 on the other side plate surface 102 of the card 100 and is disposed in the groove-shaped recess 103. Opposing the electrode 110 at an interval. In this case, since the card 100 is pressed against the card supporting surface 16 of the body 1 by the leaf spring piece 34 in the resilient state as described above, the card supporting surface 16 shown in FIG. If the distance a between the electrode and the surface of the electrode 110 falls within the tolerance range, and the height of the first locking piece 36 shown in FIG. A situation where a short circuit occurs due to contact with the electrode 110 cannot occur. However, rarely, it is conceivable that a metal dust or the like that has entered the card insertion space may be interposed between the first locking piece 36 and the electrode 110 and both may be short-circuited through the metal scrap or the like. You. Therefore, in this embodiment, an insulating process is performed in which an insulating film is formed on each of the first locking pieces 36. In this way, even if metal dust or the like that has entered the card insertion space is interposed between the first locking piece 36 and the electrode 110, there is no room for a situation in which both are electrically short-circuited. Therefore, there is no possibility that the cover 3 short-circuits the plurality of electrodes 110 on the card 100 side to cause a malfunction, thereby improving the connection reliability.
[0024]
When the card 100 of FIG. 3 is inserted into the card insertion position in the card insertion space in the normal posture as described above, the second locking of the cover 3 shown in FIG. 2 into the groove 104 of the card 100 shown in FIG. The piece 37 and the enclosure 38 are housed. Further, as shown in FIG. 6, the contact 21 of the contact 2 enters the groove-shaped recess 103 of the card 100 and rides on the electrode 110, and the contact 21 of the contact 2 is electrically connected to the electrode 110.
[0025]
Here, as shown in FIG. 7, the contact 21 of the contact 2 is formed in a valley shape by bending the distal end of the leaf spring material forming the contact 2 into a curved shape, and is inserted into the card set position. The contact 21 is resiliently contacted with the electrode 110 of the card 100 that has been connected, thereby improving the connection reliability. Therefore, when the card 100 is not inserted into the card set position, the contact 21 of the contact 2 needs to be positioned lower than the contact position of the card 100 inserted into the card set position with respect to the electrode 110. In this way, when the contact 21 of the contact 2 rides on the electrode 110 of the card 100 inserted at the card setting position, the contact 21 comes into elastic contact with the electrode 110. However, if the tip 23 of the contact 21 of the contact 2 is too low, when the card 100 is inserted into the card setting position, the tip 23 may strike the card 100 and cause buckling. There is.
[0026]
Also in this regard, since the card 100 is pressed against the card supporting surface 16 of the body 1 by the leaf spring piece 34 shown in FIG. 7 in a resilient state, the card 100 shown in FIG. If the interval b between the support surface 16 and the tip 23 of the contact 21 is made larger than the interval a between the card support surface 16 and the surface of the electrode 110, the interval b falls within the tolerance range. As long as the card 100 is inserted into the card setting position, the situation that the tip 23 of the contact 21 abuts on the card 100 cannot occur.
[0027]
As described above, the leaf spring piece 34 is provided as the card pressing means as in this embodiment, and the card 100 inserted into the card insertion space is brought into contact with the card supporting surface 16 of the body 1 by the leaf spring piece 34. When the card connector is repressed, the initial position of the contact 21 of the contact 2 is set within a tolerance range on the card connector side with the card supporting surface 16 of the body 1 as a reference plane. By setting the distance a between the one-side plate surface 101 and the surface of the electrode 110 within the tolerance range only by using the one-side plate surface 101 overlapping with the reference surface 16 as a reference surface, the card 100 can be mounted without considering the total thickness of the card 100. It is easy to improve the reliability of the card insertion operation and the connection reliability by avoiding the situation where the contact 2 buckles due to the contact 2. Since the ability to reduce the thickness of the card connector itself becomes possible to suppress extremely small tolerance stack, easily promote the thinning.
[0028]
Next, when the card 100 is erroneously inserted into the card insertion space in the upside down posture, as shown in FIG. 4 or FIG. Since the piece 36 and the second locking piece 37 are locked, the card 100 cannot be pushed. This prevents the card 100 from being pushed down to the card setting position while being turned upside down.
[0029]
In particular, in this embodiment, since the plurality of first locking pieces 36 and the second locking pieces 37 contact and lock at a plurality of locations on the leading end face 105 of the card 100, the leading end face 105 of the card 100 is locked. As a result, the load generated is distributed and received by the plurality of first locking pieces 36 and the second locking pieces 37. Therefore, even if an excessive pushing force is applied to the card 100, the first locking pieces 36 and the second locking pieces 37 buckle or the locking pieces 36, 37 are engaged between the card 100 and the housing. And the card 100 cannot be ejected.
[0030]
Further, in this embodiment, since the plate surfaces of the first locking pieces 36 and the second locking pieces 37 are in surface contact with the leading end face 105 of the card 100 and locked, the card 100 is damaged. It is also unlikely that it will stick.
[0031]
Further, even if an excessive pushing force is applied to the erroneously inserted card 100, the pushing force applied to the second locking piece 37 is received by the gate-shaped enclosure 38, so that the second locking piece 37 buckles. No buckling occurs, and as a result, the first locking piece 36 does not buckle. Therefore, an excellent erroneous insertion prevention action is exhibited as a whole, and when the card 100 is erroneously inserted in the upside down posture, it is mechanically ensured that the card 100 is inserted to the card setting position. In addition, even when an excessive pressing force is applied to the card 100, the locking piece row and the card connector are not broken.
[0032]
By the way, even when the card 100 is erroneously inserted in the upside down position and its leading end face 105 is locked by the first locking piece 36 or the second locking piece 37, the leading end face 105 is operated by the operating force applied to the card 100 or the like. Is slipped with respect to the first locking piece 36 or the second locking piece 37, the card 100 is inclined in the card insertion space, and the leading end face 105 is displaced in the vertical direction. It is rarely assumed that the leading end face 105 gets over the two locking pieces 37. Therefore, in order to improve this point, in this embodiment, the surface of the second locking surface 37 is roughened by means such as sandblasting or the like, whereby the leading end surface 105 of the card 100 and the second locking surface 37 are roughened. The frictional resistance with the piece 37 is increased. With this arrangement, when the second locking piece 37 or the first locking piece 36 is locked to the leading end face 105 of the card 100 erroneously inserted in the upside down posture and the erroneous insertion is prevented, the second locking Since the piece 37 and the leading end surface 105 of the card 100 are in contact with each other in a non-slip state, an unexpected situation such as the card 100 being inclined and getting over the first locking piece 36 is less likely to occur.
[0033]
Further, in this embodiment, as shown in FIG. 8, the card insertion slot 130 of the card insertion space is formed by each edge of the body 1 and the cover 3, and the cover of the cover forming the edge of the card insertion slot 130 is formed. The edge portion is cut and raised outward to form an invitation piece 39. In this way, even in the case of an ultra-thin card connector in which the vertical width of the card insertion slot 130 is only a few mm, the card 100 can be easily and reliably inserted from the card insertion slot 130 into the card insertion space. Become like
[0034]
【The invention's effect】
As described above, according to the card connector of the present invention, the load generated by locking the end face of the card that has been incorrectly inserted in the upside-down posture can be distributed and received at a plurality of locations. Cards are prevented from being inserted incorrectly by mechanical means.At the same time, even when an excessive force is applied to the card, the card can be damaged or the card can be prevented from being inserted incorrectly. Will not be. In addition, even if there are dimensional variations within the tolerance range of the card and the contact installation position, etc., the card ensures that the contacts are electrically connected to the electrodes of the card inserted in the card insertion position in the card insertion space in the normal posture. It becomes possible to provide a connector.
