Slider contact piece 122 which contacts the upper surface portion 121 of the shield cover 120 by applying pressure from above to the slider 150 (see FIGS. 1 and 2) moving in the insertion direction in the shield cover 120. Is installed. This slider press piece 122 always elastically biases the slider main body 152 (refer FIG. 1 and FIG. 2) of the slider 150 which moves to an insertion direction, and sets the slider 150 to the bottom plate part 112. FIG. Squeezed on.

Here, in the upper surface part 121 of the shield cover 120, the slider press-contact piece 122 processes the site | part which forms the upper surface part of the movement area | region of the slider 150, and extends downward from the back toward the front side. It is formed leaf spring material.

As a result, the slider 150 is always pressed downward to be movable in the front-rear direction in the housing 110 (see FIG. 1).

In addition, the locking jaw portion 155 is pushed on the side surface portion 120R of the shield cover 120 by pressing the slider 150 (refer to FIGS. 1 and 5) positioned horizontally in the position near the insertion hole toward the receiving portion 104. Jaw pressing piece 128 is installed to engage the notch groove portion 220 of the card 200.

The jaw pressing piece 128 is formed of an elongated strip-like inertia member formed by processing a part of the side surface portion of the shield cover 120, here, by a leaf spring. Specifically, the jaw pressing piece 128 is a portion of the card insertion port side at the side surface portion 120R of the shield cover 120 formed by processing a metal plate, and is formed from the rear end side toward the card insertion port side of the shield cover 120. It is formed by cutting out to protrude inward.

The tip end of the jaw pressing piece 128 is bent so as to protrude toward the inside, that is, the receiving portion 104 side, and the bending piece 129 (see FIG. 1) formed by this bending is placed on the card insertion opening side at the side wall portion 114. It protrudes in the housing 110 through the formed window part 114a (refer FIG. 1). The side of the slider 150 is pressed toward the receiving portion 104 side at the top end portion of the bent piece 129 protruding therein through the window portion 114a.

In this way, the jaw pressing piece 128 presses the slider 150 pushed forward by the coil spring 160 to the receiving portion 104 side at the position of the card insertion port side. Therefore, the slider 150 positioned at the position of the card insertion slot is swingably arranged against the pressing force of the jaw pressing piece 128 while the locking jaw portion 155 protrudes into the receiving portion 104. It is.

Furthermore, the heart cam groove 180 of the bottom plate portion 112 of the housing 110 is located on the upper surface portion 121 of the shield cover 120 inward from the slider card contact portion 122. Corresponding to the shape of is extended to the rear and is inclined downward.

The card unit 190 applies a pressure from above to the locking pin 170 (see FIG. 2) moving in conjunction with the slider 150 to press the heart cam groove 180 to the bottom surface of the heart cam groove 180. Slid the phase.

Fig. 9 is a view showing the relationship between the wide portion of the card portion and the heart cam groove portion, and is a partial sectional view of the card portion seen from the rear side of the connector.

The card portion 190 is formed by processing a portion of the upper surface portion 121 of the shield cover 120 that faces upward from the heart cam groove portion 180 positioned behind the portion where the slider contact piece 122 is formed. have.

The card portion 190 is a leaf spring which is inclined downward from the upper surface portion 121 of the shield cover 120, and the one end portion 172 of the locking pin 170 does not fall out of the heart cam groove portion 180. It is formed in a shape corresponding to the trajectory of the locking pin 170 to move along the cam groove 180.

Here, as shown in FIG. 8, the card part 190 is arrange | positioned so that it may overlap with the arrangement | positioning area | region of the heart cam groove part 180, when it sees from a plane, The card | shape card main part 191 and the card main part It is formed continuously to the tip of 191 and has the wide part 193 extended toward the tip side.

The heart cam groove 180 has a bottom surface having a plurality of heights different from each other, and a bottom surface (particularly the bottom surface 182d) constituting a path between the bottom surface 182e engaged with the V-shaped groove 34. The bottom surface (particularly the bottom surface 182f) that constitutes the return path has a lower level of height (see FIG. 7). Therefore, corresponding to the heights of these bottom surfaces 182c to f, the tip portion 194 of the wide portion 193 of the card portion 190 moves to the bottom surface side constituting the return side in the heart cam groove portion 180. It is inclined (see FIG. 9).

That is, in the plate-shaped card portion 190, the wide portion is formed around the axis of the card body portion 191 with respect to the card body portion 191 extending inclined downward from the rear surface of the upper surface portion 121 in the insertion direction. The front end portion 194 of 193 is twisted so that the end side of the bottom surface side which forms a return is located below. Accordingly, the tip portion 194 of the wide portion 193 is formed to be disposed in a twisted position with respect to the upper surface portion 121.

The card portion 190 is particularly the heart cam groove 180, when the one end 172 of the locking pin 170 is located near the step by the bottom surface (182a ~ 182h), the locking pin 170 The heart cam groove portion 180 is provided so as not to fall out.

As described above, the card unit 190 has a lock pin 170 on any bottom surface when the one end 172 of the lock pin 170 slides each of the bottom surfaces 180a to 180h of the heart cam groove 180. It is configured to press to give approximately the same load.

Next, with the relationship between the locking pin for moving the detachable operation of the card 200 to the memory card connector configured as described above and the operation of the locking mechanism along the heart cam groove, and the card portion for pressing the locking pin to the heart cam groove. Explain.

10 is a view showing the positional relationship between the heart cam groove, the locking pin and the pin pressing portion moving along the heart cam groove, Figure 11 to Figure 18, Figure 10, one end of the locking pin is the height of the heart cam groove Fig. 11 is a sectional side view showing the main portion showing the relationship with the card portions when they are located on different bottom surfaces. FIGS. 11-18 are main sectional side views which show the locking pin in which one end part is located in M1-M8 position on the bottom surface 182a-182h, respectively in FIG.

19 is a plan view of the housing showing the state in which the card is inserted into the connector according to the embodiment of the present invention in stages. In FIG. 19, the coil spring is omitted for convenience. FIG. 19 (a) is a plan view of the housing corresponding to FIG. 13, and FIG. 19 (b) is a plan view of the housing showing the state where the slider is in the card mounting position in the connector, and FIG. 19 (c). ) Is a plan view of the housing corresponding to FIG. 17. 20 and 21 are top plan views showing the relationship between the locking pin and the card portion corresponding to the position of one end of the locking pin shown in FIG. 20 (a) to 20 (c) show the positional relationship between the locking pin 170 and the card portion 190 in which one end portion 172 is positioned at the positions M2 to M4, respectively, and FIG. 21 (d). (G) shows the positional relationship between the locking pin 170 and the card part 190 in which the one end part 172 is located in the position M5-M8, respectively.

As shown in FIGS. 2 and 11, in the connector 100 in which the card 200 is not inserted, the slider 150 is the bottom plate portion of the housing 110 by the coil spring 160 (see FIG. 2). It is located at the card insertion port side on 112, and is elastically biased to the accommodating part 104 side by the jaw pressing piece 128. As shown in FIG.

Accordingly, in the slider 150 disposed between the bottom plate portion 112 and the upper surface portion 121 of the shield cover 120, the guide protrusion 151 of the lower surface is pressed on the front end of the slit 117, The tip portion 117a of the slit 117 is pressed toward the receiving portion 104 side. Therefore, the slider 150 is able to swing in the horizontal direction on the opposite side to the accommodating portion 104 in a state where the interference locking jaw portion 155 protrudes into the accommodating portion 104 at the position of the card insertion port side.

At this time, the locking pin 170 is disposed below the proximal end of the card main body 191 of the card 190 with the clearance G interposed therebetween. That is, the lock pin 170 is the front end side end portion of the bottom surface 182a of the base end 172 inserted into the heart cam groove 180 in the state of the connector 100 in which the card 200 is not inserted. It is arrange | positioned, without being pressed from the upper side in the state located in the side (refer FIG. 5 and FIG. 11).

The card 200 is inserted and pushed into the connector 100 in such a state from the card insertion hole 102. Then, the end of the card 200 is pressed in the insertion direction by the end of the opening 104 of the locking jaw portion 155 existing in the accommodation portion 104, that is, in the insertion region, and the slider 150 itself is accommodated in the accommodation portion 104. Rotate in the horizontal direction to the opposite side of). Accordingly, the locking jaw portion 155 is displaced in the direction away from the card 200 while sliding the side surface of the protrusion 230 of the side of the card 200 inserted into the receiving portion 104 in the jaw engaging groove 220. Enter Accordingly, the card 200 itself is held in the insertable / removable half lock state (see FIG. 1).

At this time, the protruding portion 156 is disposed to face the notch portion 210 of the card 200, and the notch portion 210 and the protruding portion 156 are engaged with each other.

Thereafter, by inserting the coil spring 160 in the insertion direction (A direction) of the card 200 against the elastic biasing force, the slider 150 moves the locking jaw 155 to the jaw recess 220. It is pressed by the inclined surface 156a by the inclined surface 212 which forms the notch part 210 in the engaged state. Accordingly, the slider 150 is guided by the slit 117 to move toward the rear end side of the connector 100. At this time, since the proximal end 172 (bending shaft) of the locking pin 170 is disposed in the heart cam groove 180, the locking pin 170 itself moves upward from the bottom surface (from the bottom surface 182a). It moves toward the bottom surface 182d via the slope 182b and the bottom surface 182c.

When the end portion 172 of the locking pin 170 moves inwardly from the bottom surface 182a in the insertion direction, from the middle portion of the bottom surface 182a, the locking pin 170 itself is from above and the upper surface of the upper portion. The card portion 190 abuts toward the insertion direction from the portion 121. Accordingly, the one end 172 slides on the bottom surface 182c while sliding under pressure on the bottom surface 182a, and moves to the position M2 shown in FIG. In the case where the one end 172 is located at the position M2 of the bottom surface 182c, as shown in FIG. 20 (a), the main body portion of the locking pin 170 is located below the card portion 190. , The card portion 190 is pressed against the bottom surface 182c.

Furthermore, when the slider 150 is deeply inserted inward, one end 172 of the locking pin 170 falls from the stepped bottom surface 182c to the bottom surface 182d, and M3 shown in FIG. Move to the location. The insertion degree of the card 200 to the connector 100 at this time is shown in Fig. 19A. Further, the positional relationship between the locking pin and the card portion 190 when the one end portion 172 is positioned at the position M3 of the bottom surface 182d is in the state shown in FIG. 20 (b).

Then, when the pushing of the card 200 pushed up to the position M3 is released, the base end portion 172 of the locking pin 170 returns to the card insertion hole side by the elastic biasing force of the coil spring. Pushed. At this time, the base end portion 172 of the locking pin 170 is moved to the bottom surface 182e side without returning to the bottom surface 182c side of the position higher than the bottom surface 182. In FIG. 14 and FIG. 20 (c), in the bottom surface 182d having a lower level than the bottom surface 182c, the step surface with the bottom surface 182c is guided toward the bottom surface 182e. The state located in M4 position of the step part as a boundary part with the bottom surface 182e is shown.

The locking pin 170 whose one end portion 172 is positioned at the position M4 of the stepped portion between the bottom surface 182d and the bottom surface 182e is reliably pressed from above by the card portion 190. In the card portion 190, the front end portion 194 (here center portion) of the wide portion 193, which presses the locking pin 170 at which one end 172 is positioned at position M4, is the bottom surface 182d. Corresponding to the bottom surface 182e having a lower height level, the inclination is inclined downward from the end portion at the bottom surface 182d side. Accordingly, the card portion 190 provides the lock pin 170 with approximately the same load as when the one end portion 172 is located on the bottom surface 182d.

As shown in FIG. 15, one end 172 of the locking pin 170 moves to the bottom surface 182e by the elastic biasing force of the coil spring 160, and thus the position on the bottom surface 182e ( In M5) it is caught and fixed to the V-shaped groove (34).

In a state where the proximal end 172 of the locking pin 170 is engaged with the V-shaped groove 34, as shown in FIG. 19B, the slider 150 is pulled out by the elastic biasing force of the coil spring. The movement in the direction is regulated and fixed to the mounting position of the card 200. That is, the card 200 is in a mounted state. At this time, the card portion 190, as shown in Fig. 21 (d), the locking pin 170 in the center portion of the front end portion 194 of the wide portion 193, the bottom surface of the V-shaped groove portion 34 The one end 172 is pressed by the substantially same load as the case where the one end part 172 is located in the position M4 on the side of 182e.

Thus, as shown in Figs. 15 and 19 (b), while the slider 150 is located at the mounting position, the electrodes on the front lower surface of the mounted card 200 are connected to a plurality of contacts (cantilever contacts) ( 130 (see FIG. 2), data of the card 200 can be read and written. In addition, at this time, since the locking jaw portion 155 enters and is engaged with the jaw groove 220 of the card 200, it is possible to prevent the card 200 from easily exiting from the connector 100 by vibration or the like. Can be.

On the other hand, when the card 200 is removed by releasing the locked state, the card 200 in the card mounted state is pushed deep into the connector 100. That is, in the state in which the card 200 is mounted, the card 200 is further inserted in the insertion direction against the elastic biasing force of the coil spring 160, so that the base end 172 of the locking pin 170 (bending shaft) ) Is released from the V-shaped groove 34.

Then, the base end 172 of the locking pin 170 on the bottom surface 182e does not return to the adjacent bottom surface 182d with a step higher than the bottom surface 182e, and is shown in Figs. 16 and 21 (e). As shown in the figure, the plate moves to the bottom surface 182f side.

The locking pin 170 whose one end 172 is located at the position M6 of the boundary portion between the bottom surface 182e and the bottom surface 182f is the tip portion 194 of the wide portion 193 of the card portion 190. It is pressed by the site | part on the bottom surface 182f side rather than the center part of (). In this case, the load applied to the locking pin 170 of the card portion 190 at the distal end portion 194 of the wide portion 193 is placed downward at the end side of the bottom surface 182f with the center portion therebetween. Since it is inclined, the one end portion 172 has approximately the same force as the case where it is located at the position M2, the position M4, or the like.

Then, one end 172 of the locking pin 170 slides from the bottom surface 182e to the bottom surface 182f side while leaving the V-shaped groove 34 and passing through the position M6, as shown in FIG. It moves on the bottom surface 182f. As described above, the locking pin 170 having the one end 172 positioned at the position M7 of the bottom surface 182f has a wide portion 193 of the card portion 190. It is pressed by the end portion of the bottom surface 182 side of the tip portion 194 of. In addition, the load applied to the locking pin 170 at this time is located in the distal end portion 194 of the wide portion 193 so as to be positioned below the end on the bottom surface 182d side of the portion that abuts the locking pin 170. Therefore, the one end 172 is substantially the same force as the case where it is located in the position M2, the position M4, etc.

In this way, the card 200 is pushed deep into the connector 100, and when the pushed state is released, the movement of the slider 150 is followed by the elastic biasing force of the coil spring 160, thereby inserting the card insertion hole 102. ) Side. Specifically, one end 172 of locking pin 170 passes from bottom surface 182f to bottom surface (slope) 182g, bottom surface 182h (see FIG. 18), and bottom surface 182a. Move to draw the return trajectory.

Specifically, one end 172 of the locking pin 170 rides on the bottom surface (slope) 182g and is referred to the position M8 (see FIG. 21 (g)) from the position M7 (see FIG. 21 (f)). Even in the case of moving to), the card portion 190 is disposed directly above the one end portion 172.

Therefore, the lock pin 170 is always in a state of being pressed on the bottom surface 182f, 182g, 182h side rather than the card part 190. As shown in FIG. In addition, the movement of the one end 172 of the locking pin 170 becomes a movement to the position of high height by raising the bottom surface 182g, and also the movement to the base end side of the card part 190. The protruding degree with respect to the upper surface part 121 of the card part 190 is slower than the distal end part 194 of the wide part 193 of the front end side. Therefore, even if one end part 172 moves to the height direction approaching the upper surface part 121, the pressing force from upper direction is substantially the same as the case where it is located in the bottom surface 182f.

The locking pin 170 guided and moved to the heart cam groove 180 is always the bottom surface 182a to 182h, as shown in FIGS. 11 to 18, particularly in the stepped portion of the heart cam groove 180. Is pressed against the heart cam groove portion 180 side by the card portion 190 formed corresponding to the height level.

As described above, even if the locking pin 170 is provided with the card part 190 in the shield cover 120, the bottom of the heart cam groove part 180 having a different height level at approximately the same pressure is always provided by the card part 190. The surface 182a to 182h is pushed to slide on each bottom surface. Therefore, the locking pin 170 can be slid without falling out without scraping the bottom surfaces 182a to 182h of the heart cam groove 180, and can accurately pass the trajectory by the heart cam groove 180.

With the movement of the locking pin 170, the slider 150 moves in the disengaging direction due to the elastic biasing force of the coil spring 160, so that the inclined surface 212 of the card 200 abuts on the inclined surface 156a is removed. Direction to move the card 200 in the release direction.

In the connector 100 of this embodiment, the slider 150 which is a slide member is covered with the shield cover 120 from the upper side, and is a slide member in the resin housing 110 which accommodates the card 200. It is arranged so that the slide can be moved in a direction and a discharge direction. Slider 150 is pressed by the card 200 in accordance with the insertion of the card 200 into the housing 110 to move deep inside the housing 110 to the mounting position of the inside, together with the card 200 when discharged It moves to the ejection position (card insertion opening side position) by the insertion port 102 side, and is hold | maintained in the state which protruded the card 200 outward from the insertion hole 102 in a discharge position. The slider 150 is elastically biased in the discharge direction by the coil spring 160. In the connector 100, the heart cam groove 180 is formed in the housing 110, and the locking pin 170 is engaged with the heart cam groove 180 in the slider 150. The locking pin 170 moves within the heart cam groove 180 according to the slide movement of the slider 150 by pressing the card 200, thereby counteracting the slider 150 against the elastic biasing force of the coil spring 160. To move it to the position to be held at the mounting position and the position to release the holding. The locking pin 170 is pushed downward by the card portion (pressing member) 190 formed by cutting a portion of the shield cover 120 downward, thereby preventing the cam pin 180 from being pulled out. The card portion 190 is formed at the position where the locking pin 170 is moved to the shield cover 120 from the discharge position and pressed toward the cam groove portion 180 during the movement of the cam groove portion 180. In addition, a clearance G is formed between the locking pin 170 at the discharge position and the upper surface portion 121 of the upper shield cover 120.

According to the present embodiment, when the card 200 is not inserted, the locking pin 170 is disposed with the clearance G interposed below the proximal end of the card main body 191 of the card unit 190. The base end portion 172 inserted into the heart cam groove portion 180 is arranged without being pressed from above in a state of being positioned on the tip side end portion side of the bottom surface 182a.

Accordingly, in the state where the card 200 is not inserted, no load is applied to the locking pin 170 at all. Therefore, reflow heating at the time of mounting the connector 100 on a board | substrate can be performed in the state which does not apply the load to the locking pin 170. FIG. That is, in the connector 100 in a state, the locking pin 170 and the card part 190 which is a part of the metal shield cover 120 are separated. Therefore, the force pressed by the locking pin 170 by the card unit 190 and the heat heated by the reflow are not transmitted to the locking pin 170. Thus, the card 190 allows the locking pin 170 to heat the reflow heat without pressing it with respect to the resin housing 110 (in detail, the bottom plate portion 112) having the heart cam groove 180. This is done.

That is, unlike the prior art, in the reflow, the center portion of the bottom surface portion of the housing, which is generated by applying pressure from the locking pin while the bottom surface portion (bottom plate portion 112) of the resin housing is softened. Deformation improvement at the time of high-temperature deformation which expanded to below affects the whole plane (including a heart cam groove part) of the housing 110 as it is, and it does not harden in the state which the fixing piece 120a of the side lifted.

Therefore, unlike the related art, deformation of the housing 110 after reflow such as lifting of the fixing piece 120a on both sides can be prevented, and the connector terminal flatness (coplanarity) after reflow can be improved.

In addition, the position card portion 190 that the locking pin 170 moves from the discharge position and presses toward the cam groove portion 180 during the movement of the cam groove portion 180 is formed corresponding to the shape of the heart cam groove portion 180. Specifically, corresponding to different height levels of the bottom surfaces 182a to 182h on which one end 172 of the locking pin 170 slides, the degree of protrusion downward from the shield cover 120 and the width of the protrusion The tip portion 194 elongated in the width direction of the portion 193 is inclined along the height of the bottom surfaces 182d to 182f so as to intersect the insertion direction. As a result, the conventional locking mechanism using the heart cam groove is not provided, and the same pressing force is applied to one end portion 172 that slides certain bottom surfaces 182a to 182h.

Moreover, in this connector 100, when ejecting the card 200, the jaw pressing piece (plate spring) 128 (plate spring) 128 of the locking jaw part 155 of the slider 150 in the carding groove 220 of a card (FIG. 1), the card is prevented from being pulled out by elastic biasing. Further, when ejecting the memory card 200, when the card in the locked state is released by pressing with a fingertip (pressing in the inserting direction), the slider increases the acceleration and moves in the card ejection direction (ejection direction) together ( 150 and the force of the memory card 200 are suppressed by the pusher piece 128 (refer FIG. 1) and the slider press-contact piece 122 (refer FIG. 1) which elastically biases the slider 150 itself downward. Accordingly, since the memory card 200 discharged from the connector is not directly pressed, it is possible to prevent the card 200 from popping out without leaving a trace of pressing the card 200 itself. Since the locking pin 170 is connected to the slider 150, the pressing force by the card unit 190 also attenuates the elastic biasing force in the disengaging direction of the slider 150 by the coil spring 160.

In addition, in the connector 100, the heart cam groove portion 180 has a right end when the front end portion of the memory card accommodated in the housing portion 104 and one side of the connector 100 (the card insertion hole 102 are viewed from the front). It is disposed between the coil spring 160 extending in the insertion direction along the side). That is, in the connector 100, the locking mechanism 140 including the housing 104, the coil spring 160 and the heart cam groove 180 that elastically bias the slider 150 on the housing 110. Is reasonably arranged to be water-soluble.

Therefore, in the connector 100, the width of the connector 100 is formed to have a length close to the width of the sum of the width of the memory card itself and the width of the locking mechanism 140, and the size of the connector 100 is reduced. Saving of mounting space is also planned.

Moreover, the slider press-contact piece 122 is press-contacted to the slider 150 located in the card insertion port side. Therefore, when the slider 150 returns to the position of the card insertion port side from the card holding position, which is the position of the rearmost side in the receiving portion, by the elastic biasing force of the coil spring 160, that is, at the time of the card ejection operation, The slider contact piece 122 may mainly reduce the moving force of the slider 150 due to the elastic biasing force together with the jaw pressing piece 128.

The memory card connector according to the present invention is not limited to the above embodiments, and various modifications can be made. In addition, the present invention may make various schematic modifications without departing from the spirit of the present invention, and the name is natural for the present invention.

The memory card connector according to the present invention has an effect that the housing itself is not deformed well even when the board is reflowed in the board mounting, and thus can be preferably mounted. It is useful as a push-in push-out memory card connector for mounting a memory card.
