[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a function expanding box for electronic equipment such as a portable personal computer.

[0002]

2. Description of the Related Art For example, as disclosed in Japanese Utility Model Laid-Open No. 3-119220, the portability of a portable electronic device such as a so-called notebook type personal computer, a laptop type personal computer, etc. is ensured and its function is improved. In order to expand to the same level as or more than a desktop personal computer, it has been proposed to provide a function expansion box containing a circuit for expanding the function and attach / detach the portable electronic device to this box.

The function expanding box and the portable electronic device are electrically connected to each other, for example, by inserting a male connector provided in the portable electronic device into a female connector provided in the function expanding box. Further, in order to prevent these connectors from being accidentally pulled out, a means for prohibiting relative movement of the connectors in the insertion / removal direction is provided.

[0004]

However, in the conventional function expansion box of this type, only prohibition of relative movement of the connectors in the insertion / removal direction is taken into consideration, and for example, in the vertical direction perpendicular to the insertion / removal direction. No consideration was given to the move to. Therefore, when connecting the function expansion box and the portable electronic device, if the portable electronic device is to be lifted in the vertical direction, the stress concentrates on the connection connector, and there is a danger that the connector will be broken.

Further, since the user attaches and detaches the portable electronic device to and from the conventional function expansion box, it is not always possible to accurately move the portable electronic device and the connector relative to each other in the insertion / removal direction of the connector. The pins and the receptor are easily deformed, which causes poor contact.

From the opening (52), a sub connector portion (54) (not shown in FIGS. 1 and 2) described later is interlocked with the second lever (53) on the side wall of the storage portion (4) and the mounting portion (2). It is possible to raise to the surface.

FIG. 8 shows an interlocking mechanism between the first lever (47) and the first to third extruding members (48) to (50) and an interlocking mechanism between the second lever (53) and the sub connector portion (54). 9 and 10 are perspective views showing these interlocking mechanisms, and each interlocking mechanism will be described below with reference to FIGS. 8 to 10.

The first to third pushing members (48) to (50) are rotatably supported by the first to third crank members (55) to (57), respectively. In addition, the crank member (5
One end of each of 5) to (57) is fixed to a first shaft (58) that is rotatably supported in the storage section (4). Therefore, with the rotation of the first shaft (58), the first to third pushing members (48) to (50) can slide in the sliding direction of the tray (5) (direction of arrow A in the figure). is there.

A slide plate (60) is connected to the other end of the first crank member (55) via a connecting pin (59). The slide plate (60) extends in the sliding direction of the tray (5) at the left end of the mounting portion (2). In addition, an opening (61) is formed at approximately the center of the slide plate (60).
(See FIGS. 9 and 10), and the opening (6
The first lever (47) on the front end side of the mounting portion (2) of 1)
Is rotatably supported by a shaft (62) (see FIG. 8).

The first lever (47) has a projecting piece (63) projecting inwardly of the mounting portion (2) on its rear surface. The tip of the projecting piece (63) abuts on a guide plate (66) mounted outside one end of a swing plate (65) rotatably held by a shaft (64) in the mounting portion (2). Contact.

The swing plate (65) is provided with a second spring (6).
8) is always urged counterclockwise in FIG. 8 and, by driving the solenoid (68), it is rotated clockwise against the urging force of the spring (67). The solenoid (68) is driven for a predetermined time (10 seconds in this embodiment) after the switch (69) shown in FIGS. 1 and 2 is pressed.
As is done, it is done by an electrical circuit not shown.

Next, the relationship between the first lever (47) and the swing plate (65) will be described with reference to FIGS. 11 to 13.

FIG. 11 shows the state when the solenoid (68) is not driven. At this time, the oscillating plate (65) is urged counterclockwise by the spring (67), so that the protrusion (63) of the first lever (47) is in a positional relationship with the guide plate (66). Then, the first lever (47) is completely stored inside the mounting portion (2) (non-operating position). On the other hand, FIG.
When the solenoid (68) is driven as shown in FIG. 5, the rocking plate (65) rotates clockwise against the urging force of the spring (67), and as a result, the first lever (47) moves the mounting portion (2). )
Stick out (operation position). Thereby, the mounting portion (2) of the slide plate (60) by the first lever (47).
Sliding operation toward the front end becomes easy. Further, the drive of the solenoid (68) is held for a predetermined time, and the guide plate (66) is held substantially parallel to the slide plate (60) during this time. Therefore, as shown in FIG. The 1 lever (47) acts as a posture holding and guiding role.

Further, the action of the oscillating plate (65) includes the action of locking the tray (5). That is, FIG.
When the solenoid (68) is not driven in the set state of the tray (5) as shown in FIG. 11, the notch (23) of the tray (5) as shown by the dashed line in FIG.
In the vicinity of the guide plate (66) of 5), the lock member (70) extends in the direction perpendicular to the paper surface of FIG. 11 and has a sectional shape similar to that of the notch (23). Therefore, FIG.
In the state of 1, the tray (5) is fixed in the set state position. On the other hand, as shown in FIG. 12 or FIG.
Since the notch (23) and the lock member (70) are disengaged in the state in which the drive member (8) is driven, the tray (5) can be slid.

In this embodiment, the solenoid (68) is used.
Was driven within a predetermined time after the switch (69) was pressed down. This is because the lock release period between the cutout (23) and the lock member (70) due to an erroneous operation of the switch (69) is shortened as much as possible. This is to prevent the desired tray (5) from sliding. If the undesired slide of the tray (5) occurs during the use of the personal computer, the electrical connection between the personal computer and the extension box (1) will be opened, which will cause a malfunction as described later. On the other hand, after driving the solenoid (68) to press the switch (69), the tray (5) is driven.
It is also possible to configure so that the drive state is not released until is moved from the set state position. However, at this time, the malfunction is prevented by providing a mechanism capable of locking the tray (5) at the set position regardless of the driving of the solenoid (68).

Returning to FIGS. 8 to 10, the first crank member (55) is constantly urged to the rear of the storage section (4) by the third spring (71). Therefore, each extruded member (4
8) to (50) and the slide plate (60) are also urged in the rearward direction of the storage section (4) by the urging force of the third spring (71).

The sub-connector (54) has a second shaft (72) axially supported in parallel with the first shaft (58) in the accommodating portion (4) and one end fixed to the second shaft (72). Submount (76), first and second auxiliary extruding members (74) (75) fixed to the left and right ends of the other end of the submount (76), and the auxiliary extruding members (74) (7).
5) and a second connector (73) disposed on the submount (76). In addition, the sub connector (5
4) is the operation of the second lever (53) fixed to one end of the second shaft (72), so that the first and second auxiliary push-out members (74) (75) and the second connector (73) shown in FIG. ,
The second shaft (72) is rotated about the second shaft (72) so as to rise to the surface of the mounting portion (2) through the opening (52) shown in FIG. FIG. 9 shows a state in which the auxiliary push-out members (74) (75) and the second connector (73) are housed in the housing part (4), and FIG. 10 is raised to the surface of the mounting part (2). Indicates the status. In this raised state, the first and second auxiliary extrusion members (74)
(75) is located in front of the first and second extruding members (48) and (49), respectively. Further, the first and second extruding members (7
4) and (75) are both urged to the left in the figure (the direction of the second shaft (72) in FIG. 10) by the fourth spring (77) as shown in FIG. A push rod (7) slidable in the communication passage communicating with the hole.
8) (79). From the state shown in FIG. 10, the push rods (78) (79) push the first and second push members (48) (49) toward the mounting portion (2) as the slide plate (60) slides. Then, the tip of the rod is pushed out (78).
The (79) is brought into contact with the second shaft (72) side, and the other end of the push rods (78) (79) is projected toward the front end of the mounting section (2).

Next, the first to third extruding members (48) to

As shown in FIG. 5, the first connector (51) is an A4PC (1
It is connected to an external connector (80) arranged on the back surface of 1). Further, in this state, as shown in FIG. 11, the notch (23) of the tray (5) and the lock member (70) are in a locked state, and the tray (5) is prohibited from sliding. Furthermore,
As shown in FIG. 6, since the hook-shaped part (39) of the hook means (34) is locked to the locking part (41) on the bottom surface of the A4PC (11), an upward force acts on the A4PC (11). However, the A4PC (11) will not be removed from the tray (5).

In such a state, the switch (6
When the solenoid 9) is operated, the solenoid 68 is driven,
As shown in FIG. 2, the rocking plate (65) is rotated clockwise so that the first lever (47) is projected to the side surface of the mounting portion (2) and the notch (23) and the locking member (70) are locked. The state is released. When the locked state is released, the tray (5) is urged toward the released state position by the urging force of the first spring (28), but actually the first connector (51) and the external Since the connection force with the connection connector (80) is larger than the urging force of the first spring (28), the positional relationship shown in FIG. 15 is maintained.

After that, when the first lever (47) is slid toward the front end of the mounting portion (2) as shown in FIG. 13, the first to third extruding members (48) to (5) are interlocked with this sliding.
0) protrudes toward the mounting portion (2), and as shown in FIG.
The back surface of the 4PC (11) is pushed out toward the front end of the mounting portion (2), and the first connector (51) and the external connection connector (80).
Will be disconnected. At this time, the first connector (5
Since 1) is located at the center between the second and third extruding members (49) and (50), stress is evenly applied to the connector, and damage to pins and the like forming the connector can be prevented.

When the connection between the first connector (51) and the external connection connector (80) is released as shown in FIG. 16, the tray (5) is free to slide, and the A4PC (11) is free.
Even if the tray itself is heavy, the tray (5) can be easily slid to the released position by the biasing force of the first spring (28).

A sub-PC is used instead of the A4PC (11).
(12) is placed on the tray (5) at a predetermined position (see FIG. 3) defined by the first, third to fifth regulating members (6), (8) to (10), and the tray ( 5) when sliding 5) to the set position (see FIG. 1).
The second lever (53) must be operated in advance so that the first and second auxiliary pushing members (74) (75) and the second connector (73) are exposed on the surface of the mounting portion (2) as shown in FIG. As a result, as shown in FIG. 17, when the tray (5) reaches the set position, the second connector (73) moves to the sub PC (1

(12) is prevented from being disengaged in the upward direction, and the tray (5) is also prohibited from sliding due to the engagement of the lock member (70) and the notch (23). When the switch (69) is operated in such a state, the locking is released and the tray (5) can be freely slid, but the connection force between the second connector (73) and the external connector (82) causes The positional relationship shown in 17 is maintained. After that, when the first lever (47) is slid toward the front end of the placing portion (2) as shown in FIG. 13, the first to third parts are interlocked with this sliding.
Although the push-out members (48) to (50) project toward the mounting portion (2), the back surface of the sub-PC (12) and the standing wall (3) of the storage portion (4) are separated from each other, and thus the first lever (47) is formed. ) Is operated toward the front end of the placing section (2) to the maximum, the tips of the first to third extruding members (48) to (50) do not directly contact the back surface of the sub-PC (12). However, the extrusion rod (7) of the first and second auxiliary extrusion members (74) (75) located between the sub-PC (12) and the first and second extrusion members (48) (49).
8) (79) is the first and second extruding members (48) (4)
With the projection of 9), the back of the sub PC (12) is projected and the rear surface of the sub PC (12) is pushed out toward the front end of the mounting portion (2). Therefore, as shown in FIG. 18, the second connector (73)
The external connection connector (82) is disconnected, and the tray (5) can be freely slid. still,
The second connector (73) and the external connection connector (82)
When the connection with the sub PC (12) is released (8
Since the connector (82) is located in the center of the first and second auxiliary extruding members (74) and (75), the stress applied to 2) is even and does not damage the pins or the like of the connector.

On the other hand, the microswitch (33) on the mounting portion (2) is mounted on the tray (5) as described above with the A4PC (1).
It is turned on only when 1) is placed and the tray (5) is in the released state. The operation position of the second operation lever (53) is detected by a detection means such as a micro switch (not shown). Therefore, the second connector (7

According to the present invention, relative movement of the function expansion box and the portable electronic device in the insertion / removal direction of the connector can be accurately performed by sliding the tray. At times, it is possible to prevent the pins and the receptor of the connector from being deformed. Further, when the function expansion box and the portable electronic device are connected, the portable electronic device can be fixed on the mounting portion of the function expansion box by the hook means, so that undesired relative movement in the vertical direction is performed. Can be prevented. Furthermore, the hook means automatically inhibits relative movement of the function expansion box and the portable electronic device in the vertical direction only when the function extension box and the portable electronic device are connected together in conjunction with the slide of the tray. Operability is improved because a separate operation for prohibition is unnecessary.
