Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a card connector,
In particular, the present invention relates to a card connector having a slider which is pushed by a card inserted into a body and is pushed forward from an initial position toward a pushing position corresponding to a card setting position.

[0002]

2. Description of the Related Art A card connector of this type is disclosed in
No. 185286 (prior example). In this card connector, a card inserted into the body is held in a body as a housing by a slider being slid back and forth in a state where a slider is constantly biased backward by a spring force. Is provided with an engaging surface for engaging. When the card is inserted into the body in the normal posture, the card is engaged with the engagement surface of the slider, and the slider is pushed forward against the bias of the spring.

[0003] The slider is provided with a pin member formed by bending a chevron-shaped engaging body on a part of an elastic wire rod in a cantilever manner. There is a recess that can be fitted.
Then, when the card is inserted into the body in the normal posture, the slider remains stopped at the initial position (ie, without moving the slider located at the initial position), and the front side of one end face of the card is moved. The portion gets over while displacing the engaging body outward, whereby the engaging body fits into the recess of the card by the elasticity of the pin member.
Thus, in the state where the engagement body is fitted in the recess of the card, a half lock function is exhibited in which the card is prevented from being independently retracted from the slider unless the card is forcibly pulled backward. In this state, when the slider is further pushed by the card and reaches the pushing position, a full lock function by a lock mechanism for fixing the position of the slider to the body (a lock mechanism is constituted by a cam mechanism in the preceding example) is provided. This prevents the slider from moving backward. When the full lock function is released, the slider retreats to the initial position by the force of the spring urging the slider rearward, and the card is pushed rearward by the slider.

On the other hand, when the card is inserted into the body in an upside-down posture, the other end surface of the card may ride on the engaging body and displace the engaging body outward.
In such a case, the card pushes the slider from the initial position to the pushing position while the other end surface of the card rides on the engaging body and is displaced outward, but in this case, the full lock function by the lock mechanism works. When the pressing force on the card is released by releasing the hand from the card, the slider retreats to the initial position by the force of the spring biasing the slider backward, and the card is pushed backward by the slider, In this way, the card once pushed in is immediately pushed out without being fully locked at the pushing position of the slider, so that the operator recognizes that the card has been inserted in the upside down position (that is, the card has been reversely inserted). .

[0005]

However, as seen in the above-mentioned prior art, the distinction between the case where the card is inserted in the normal posture and the case where the card is inserted in the upside down posture is made by the card being pushed by the slider. When the card inserted into the body is immediately pushed out without being fully locked at the pushing position of the slider, the operation is performed when the card is inserted into the body and immediately pushed out without being fully locked. The operator does not always recognize that the card has been reversely inserted in the upside down position, and the operator may erroneously recognize that the card connector or the device to which the card connector is attached is broken.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and makes a card stroke different from a pushing stroke when a card is inserted in a normal posture and a pushing stroke when a card is inserted in a reversed posture. It is an object of the present invention to provide a card connector that allows an operator who has inserted a card in an upside down posture to correctly and easily recognize reverse insertion of a card.

[0007]

SUMMARY OF THE INVENTION A card connector according to the present invention has a body into which a card is inserted, which is engaged with a card inserted into the body and is moved from an initial position to a pushing position corresponding to a card setting position. A slider that is pushed forward toward the front is slidably held back and forth while being elastically urged rearward. Also, an engaging body that fits into the recess provided on one side in the width direction of the card inserted into the body in the normal posture in the slider and positions the card with respect to the slider, and the engaging body is formed by the recess. An elastic body that is constantly urged in the direction of insertion into the place, and the engaging body is provided for allowing the one end face in the width direction of the card inserted into the body in the normal posture to ride up without moving the slider. When the card is pulled to the rear of the slider from a state in which the engaging body is fitted in the recess, the side guide surface and one end surface in the width direction of the card are allowed to climb up without moving the slider. And a front guide surface.

Further, a hook portion is added to the body,
A hook portion which is displaceable between an outer position where the slider can be hooked on the hook portion and an inner position where the slider cannot be hooked, and is always elastically biased toward the inner position; And the hooking position between the hooking portion and the hook portion is located at a position where the slider is moving from the initial position to the pushing position, and the rear guide surface of the engaging body is provided. Has a function of allowing the other end in the width direction of the card inserted into the body in the upside-down posture to ride on the engaging body without moving the slider, and the card inserted into the body in the upside-down posture. A pressing portion that pushes out the hook portion toward an outer position as the engaging body having the other end surface in the width direction climbed up against the biasing force of the elastic body is retracted to the side, and the engaging body is It is installed continuously.

According to this structure, when the card is inserted into the body in the normal posture, the one end face of the card gets over while displacing the engaging body to the outside while the slider remains stopped at the initial position. Since the engagement body fits into the recess by the elasticity of the elastic body, a half lock function of preventing the card from retreating from the slider alone is exhibited. In this state, the slider can be further pushed to the pushing position by the card.

On the other hand, when the card is reversely inserted into the body in an upside-down posture, the other end surface of the card is engaged by the rear guide surface of the engaging member while the slider remains stopped at the initial position. And the engaging body is retracted (displaced) outward (to the side) against the bias of the elastic body.
When the engaging body retreats to the side in this way, the pressing portion connected to the engaging body pushes the hook portion toward the outer position accordingly, and thereafter, the other end surface of the card rides on the engaging body. When the slider is pushed from the initial position toward the pushing position, the hook portion moves forward together with the slider and engages with the engaging portion added to the body, and the slider moves forward beyond the engaging position. To prevent that. Since the hooking position between the hooking portion and the hook portion is located at a position where the slider is moving from the initial position to the pushing position, the operator pushes the card before the slider reaches the pushing position. And the operator will recognize that the card has been reversely inserted in the upside down position.

In the present invention, the above-mentioned elastic body made of a spring plate;
The engaging body consisting of a chevron part connected to the tip of the spring plate, the pressing part consisting of a protruding piece connected to the engaging body via the spring plate, the hook part, and the hook It is desirable that a sheet metal unit integrally provided with a spring piece part that constantly urges the part toward the inside position be attached to the slider. According to this, since the elastic body, the engagement body, the pressing portion, the hook portion, and the spring piece portion are formed by a single component called a sheet metal unit, an increase in the number of components is suppressed, and the number of assembly steps and component costs are reduced. In addition, the required positional accuracy of the pressing portion, the hook portion, and the like can be easily secured, and the operation stability is improved.

In the present invention, it is preferable that the engaging portion is formed by a front opening edge of the opening in a frame member having an opening that allows the hook portion to retreat. According to this, when the body is made of a synthetic resin molded body, the frame member serves to reinforce the body, so that the body can be thinned and its compactness can be promoted.

Thereafter, the card 100 is further inserted, and the slider 2 is pushed forward together with the card 100 against the bias of the spring 7, so that the slider 2 reaches the pushed position and is fully locked ( The card 100 is inserted into a card setting position (indicated by a phantom line in FIG. 7), and the contact of the contact member of the body 1 resiliently contacts the electrode of the card 100 (not shown). When the full lock state is released from this state, the slider 2 moves rearward by the bias of the spring 7 and returns to the initial position shown in FIG.

Next, as shown in FIG. 8, when the card 100 is reversely inserted into the
Is stopped at the initial position, the other end surface 102 in the width direction of the card 100 rides on the engaging body 63 by the action of the rear guide surface 63a of the engaging body 63, and the engaging body 63 is attached to the elastic piece 62. Retreat to the side against the forces. When the engaging body 63 retreats to the side in this way, the engaging body 63
Since the pressing portion 69 connected to the spring portion 62 through the elastic piece portion 62 pushes the spring piece portion 67 toward the outer position, the hook portion 68
Is also pushed out of the opening 81 of the frame member 8 toward the outside position. Thereafter, when the slider 2 is pushed forward as shown by the arrow F from the initial position to the pushing position while the other end surface 102 of the card 100 rides on the engagement body 63, the card 100 23, the slider 2 is pushed in, and the hook portion 68 moves forward together with the slider 2 to move the frame member 8 as shown in FIG.

The hooking position between the hooking portion 82 and the hook portion 68 is located slightly before the position of the hook portion 68 when the slider 2 is located at the initial position. Before reaching the pushing position, the card 100 cannot be pushed in, so that the operator notices that the card 100 has been reversely inserted in the inverted posture. Therefore, the operator can use the card 100
Can be pulled out of the body 1 and reinserted in a normal posture. When the card 100 is pulled out of the body 1, the slider 2 moves rearward by the bias of the spring 7, and returns to the initial position shown in FIG. Further, the engaging body 63 protrudes inward from the opening 29 by the elasticity of the elastic piece 62, and the hook 68 returns to the inner position by the elasticity of the spring piece 67.

As described above, according to this embodiment, the pushing stroke when the card 100 is reversely inserted in the upside down posture is shorter than the pushing stroke when the card 100 is inserted in the normal posture. 100
Can be easily and correctly recognized by the operator who has reversely inserted the card 100 upside down.

In this embodiment, the elastic pieces 62,
Engagement body 63, pressing part 69, hook part 68, spring piece part 67
8 is formed by a single component called the sheet metal unit 6, not only is the increase in the number of components suppressed, so that the number of assembling steps and component costs are reduced, but also the pressing portion 69 and the hook portion 6 are formed.
The required positional accuracy, such as 89, was easily ensured, and excellent operational stability was obtained. Further, since the frame member 82 made of sheet metal reinforces the body 1 made of a synthetic resin molded body, it is possible to make the body thinner and promote its compactness.

Next, the structure and operation of the cam mechanism 4 will be described.
As shown in FIG. 4, the cam portion 41 has a cam groove 42,
A pin 52 held by the slider 2 is inserted into the cam groove 42.
Has come to imitate. The cam groove 42 includes a groove-shaped forward path 43 for guiding the pin 52 to the front F of the cam portion 41, a stepped locking section 44 for locking the pin 52 at an end point of the groove-shaped forward path 43, The pin member 5 (see FIG. 5 and the like) is provided by guiding the pin 52 rearward with the locking portion 44 as a starting point.
And a groove-shaped return path 45 for guiding to the starting point P of the groove-shaped forward path 43 without forcing excessive deformation, and the groove-shaped return path 45 is located outside the groove-shaped forward path 43. Of these, the groove-shaped forward path 43 reaches an end point (locking section 44) through a sloping section 43a and a detour section 43b that extend diagonally inward from the position of the starting point P, and the groove-shaped return path 45 includes a locking section. It has a detour portion 45a protruding outward from 44 and a return main portion 45b extending straight backward from the detour portion 45a. In addition, the groove-shaped forward path 4 continues straight to the return path main portion 45b.
The evacuation route 46 extending to the side of the starting point P of the third evacuation route 43 is added, and as shown in FIG.
6 and the starting point P of the groove-shaped forward path 43
And the evacuation route 46 are communicated with each other by an inclined surface 47. This inclined surface 47 is provided with a pin 52 located at the starting point P of the groove-shaped forward path 43.
Is pushed outward, the pin 52 is slid to get on the evacuation path 46, or the pin 52 riding on the evacuation path 46 is slid to move to the start point P of the groove-shaped forward path 43. Has functions.

In the cam groove 42 having the above-described shape, the pin 52 goes backward at the starting point of the detour 43b of the groove-shaped forward path 43, on both sides of the locking part 44, and at the junction of the groove-shaped return path 45 with the groove-shaped forward path 43. Are provided, respectively. FIG. 6 shows the step portion 33 formed at the boundary between the detour portion 45a and the return main portion 45b.

On the other hand, as shown in FIG. 5, the pin 52 has a curved surface (a lower end) whose outer peripheral edge is wider than the retreat path 46 and has a downward slope toward the groove-shaped forward path 43. An inclined surface 53 is formed.
For this reason, as shown by the arrow f in FIG. 5, when the pin member 5 is pressed by the curved portion 66 of the spring body 61 described in FIG. 3 and the like, and the inclined surface 53 of the pin 52 is pressed against the evacuation path 46, The pin 52 is moved from the evacuation path 46 to the groove-shaped forward path 43.
To the start point P of.

Next, the operation of the cam mechanism 4 will be described.

When the slider 4 is positioned at the initial position, the card 100 is inserted into the body 1 in a normal posture and forward, and one end surface 101 of the card 100 rides on the engaging body 63 to move the engaging body 63 to the outside. When retracted in the direction, the pressing portion 64 pushes the pin member 5 so that the pin 52 (see FIG. 4) located at the starting point P of the groove-shaped forward path 43 of the cam groove 42 on the inclined surface 47 described with reference to FIG. Although the pin 52 is slid and pushed out to the evacuation path 46, the pin 52 thus pushed out to the evacuation path 46 has the engaging body 63 as shown in FIG.
6 and the pressing portion 64 is displaced inward,
The inclined surface 53 of the pin 52 slides down the inclined surface 47 from the evacuation path 46 by the action of the spring body 61 and returns to the starting point P of the groove-shaped forward path 43.

Thereafter, when the card 100 is pushed (push-in operation) and the slider 2 is pushed forward together with the card 100 against the bias of the spring 7, the pins 52 of the pin member 5 following the slider 2 are pushed. Moves to the front F shown by the arrow in FIG. 4 without forcibly deforming the groove-shaped forward path 43 of the cam groove 42 and hits the front end of the bypass part 43b.
At this time, when the push action on the card 100 is released, the slider 2 is pushed back by the force of the spring 7, and
The pin 52 reaches the end point of the groove-shaped forward path 43 through the bypass 43 b and is locked by the locking portion 44. At this time, the full lock function of preventing the slider 2 that half-locks the card 100 from retreating is exhibited, and the card 10
0 is inserted into the card setting position (indicated by phantom lines in FIG. 7), and the contact of the contact member on the body 1 resiliently contacts the electrode of the card 100.

When the card 100 is strongly pulled in the pulling-out direction from the full lock state, the one side end face 10 of the card 100 is acted on by the action of the inclined front guide surface 63b of the engagement body 63.
The front portion of the vehicle 1 rides on the engaging body 63 and the engaging body 63 is retracted outward, whereby the half-lock state is released. At the same time, the pressing portion 64 pushes the pin member 5 to lock the pin 52 locked by the locking portion 44 at the end point of the groove-shaped forward path 43 to the groove-shaped return path 45 via the detour 45a shown in FIG.
, The full lock state is released.

When the full lock state is released in this way,
The slider 2 moves rearward by the bias of the spring 7, and accordingly, the pin 52 moves from the groove-shaped return path 45 to the retreat path 46, and returns to the starting point P of the groove-shaped forward path 42. Also,
The slider 2 returns to the initial position shown in FIG.

Next, as shown in FIG. 8, when the card 100 is reversely inserted into the
Is stopped at the initial position, the other end face 102 in the width direction of the card 100 rides on the engaging body 63 and retreats the engaging body 63 to the side against the bias of the elastic piece 62. .
For this reason, the pressing portion 64 presses the pin member 5 and the groove-shaped forward path 4
The pin 52 located at the start point P of No. 3 is pushed out to the evacuation path 46 via the inclined surface 47 shown in FIG. Therefore, after that, slider 2
When the pin 52 is pushed forward from the initial position to a position corresponding to the hooking position between the hook portion 82 and the hook portion 68 shown in FIG.
Or from the evacuation path 46 to the groove-shaped return path 45
to go into. Therefore, a situation in which the pin member 5 is forcedly deformed does not occur. In addition, the pin 52 is
There is no situation in which the vehicle is fully locked by being locked to the lock.

As described above, in this embodiment, the card 100 is inserted upside down while the push / push operation is enabled by employing the cam mechanism 4 composed of the cam portion 41 and the pin member 5. The pin member 5 is not forced to be deformed even when it is moved. Therefore, it is possible to provide a card connector having a cam mechanism that does not cause a situation in which the half lock function or the full lock function is impaired. This makes it possible to provide a highly reliable half-lock function and full-lock function even when the pin member must be made of an extremely thin wire as the card connector becomes thinner.

According to the embodiment described with reference to FIGS.
Not only can the operator reliably recognize that the card 100 has been reversely inserted in the upside down position, but also the card 1
When 00 is reversely inserted in the upside down position, the card 100
The pin member 5 of the cam mechanism 4 that exerts the full lock function when the card is inserted to the card setting position is not forced to deform excessively, and the operation reliability of the full lock function is improved.

[0040]

According to the present invention, since the pushing stroke when the card is reversely inserted in the upside down posture is shorter than the pushing stroke when the card is inserted in the normal posture, the card is reversely inserted in the upside down posture. The operator can correctly and easily recognize the reverse insertion of the card. Therefore, when the card is pushed out immediately after being inserted without being fully locked, the operator is less likely to erroneously determine that the card connector or the device to which it is attached is broken.
