In the support stand device disclosed in Patent Document 1, the electrical device is detached from the support stand device because the electrical device is fixed to the mounting surface of the support stand device by the engagement of the mounting screw and the mounting screw hole. Is prevented. However, it is troublesome to attach and detach electric devices.
On the other hand, since the cradle disclosed in Patent Document 2 only needs to place the electrical device on the stand body of the cradle body, the electrical device can be easily attached and detached. However, when such a cradle is used in a vehicle, the sway of the vehicle is transmitted to the cradle, and there is a possibility that the electric device falls off from the cradle.

  The present invention has been made in view of such circumstances, and a main object of the present invention is to bring an electric device between an upper holding piece and a lower stand body of an electric device by bringing the holding piece into and out of contact with the electric device. An object of the present invention is to provide a stand device that can reliably prevent an electrical device from falling off and can easily attach and detach the electrical device by adopting a configuration in which the device is sandwiched.

  Another object of the present invention is to automatically hold an electric device by placing the electric device on the mounting table, and to release the engagement of the fixing portion that engages with the mounting table and fixes the mounting table. Accordingly, an object of the present invention is to provide a stand device that can more easily attach and detach an electric device by automatically releasing the holding of the electric device.

  Another object of the present invention is to prevent vertical movement of a mounting table on which an electric device is to be mounted when the electric device is not mounted, and when the electric device is mounted, the connectors are connected to each other. It is in providing the stand apparatus which can connect connectors reliably by setting it as the structure which prevents an apparatus side connector from falling unnecessarily before doing.

  Still another object of the present invention is to automatically release the locking between the mounting table and the vertical movement preventing portion for preventing the mounting table from moving up and down, and to prevent the vertical movement. By providing a structure in which connectors are connected to each other before the locking of the part is released, it is possible to provide a stand device that can easily attach an electrical device and can reliably connect the connectors to each other. It is in.

  A stand device according to a first aspect of the present invention is a stand device that detachably supports an electric device, the stand device on which the electric device is placed, and an electric device that is placed on the stand main body, and is arranged above the electric device. A clamping piece for clamping the device to and from the stand main body, and a contact / separation mechanism for bringing the clamping piece into and out of contact with the clamping position of the electrical device.

  In the stand device according to the second aspect of the present invention, the holding piece is provided at one end of a holding member that is formed in an inverted L shape in an elevational view, and the stand body is an electric device to be placed The mounting table is configured to be lowered when pressed downward, and is detachably provided with respect to the mounting table. The mounting table is engaged with the mounting table at a position where the mounting table is lowered. A fixing portion for fixing the mounting table, and a position that is arranged below the mounting table, is compressed by the lowered mounting table, and is restored by disengaging the fixing unit and the mounting table is raised An elastic member that raises the mounting table, and the contact / separation mechanism rotatably supports the other end portion of the holding member, and the holding piece moves as the mounting table descends. The clamping piece approaches the clamping position, and the clamping piece moves along with the rise of the mounting table. Characterized in that said clamping member so as to apart from the bellflower lifting position are so as to rotate.

  A stand device according to a third aspect of the present invention includes a device-side connector connected to a device-side connector included in an electrical device mounted on the mounting table, and the device-side connector mounted thereon, and the substrate is mounted on the mounting table. A printed circuit board that is connected to the mounting table so as to be movable in the surface direction, and a vertical movement preventing unit that prevents the mounting table from moving up and down before the device-side connector and the device-side connector are connected; Is further provided.

  In the stand device according to a fourth aspect of the present invention, the vertical movement preventing portion is detachably provided to the mounting table, and the mounting table is locked to the mounting table at the raised position. And the device side connector is unlocked by being pressed by the electric device mounted on the mounting table, before the locking of the vertical movement preventing portion is released. The electric device is arranged so as to be connected to a device-side connector included in the electric device.

In the first invention, the stand main body, the clamping piece, and the contact / separation mechanism are provided.
The user places the electric device on the stand body.
When the electrical device is placed on the stand body, the contacting / separating mechanism causes the sandwiching piece to approach the sandwiching position of the electrical device, so that the sandwiching piece disposed on the upper side of the electrical device placed on the stand body The electric device is easily sandwiched between the stand body on which the electric device is placed (that is, disposed on the lower side of the electric device). That is, the stand device of the present invention supports the electric device in a state where the electric device is held between the holding piece and the stand body.

In addition, since the contact / separation mechanism separates the holding piece from the holding position of the electric device, the holding piece is separated from the upper side of the electric device placed on the stand body, so that the holding of the electric device is easily released. The user easily removes the electrical device from the stand device in a state where the clamping of the electrical device is released.
In addition, the structure which a user performs manual contact | separation by the contact / separation mechanism may be performed manually, for example, it is a structure performed automatically, for example, when a user mounts an electric equipment in a stand main body. Also good.

In the second aspect of the invention, the clamping member is formed in an inverted L shape when viewed from the top. The clamping member is provided with a clamping piece at one end, and the other end is rotatably supported by a contact / separation mechanism.
The stand main body has a mounting table, a fixing portion, and an elastic member.

The user places the electric device on the mounting table. At this time, the mounting table is pressed downward by the electric device.
Since the elastic member is arranged on the lower side of the mounting table, the mounting table is in a state separated from the bottom surface of the stand main body, for example, and is lowered when pressed downward by an electric device to be mounted. The elastic member is compressed by the lowered mounting table, and the fixing portion engages with the mounting table at a position where the mounting table is lowered to fix the mounting table.
The contact / separation mechanism rotates the holding member so that the holding piece approaches the holding position of the electric device as the mounting table is lowered.
As a result, the holding piece approaches the upper side of the electric device placed on the stand main body, so that the electric device is automatically held between the holding piece and the stand main body.

The fixing portion is provided so as to be detachable from the mounting table. For example, the user manually releases the engagement between the fixing portion and the mounting table.
When the engagement between the fixing portion and the mounting table is released, the mounting table is raised by the restoring force of the elastic member. The contact / separation mechanism rotates the holding member so that the holding piece is separated from the holding position of the electric device as the mounting table is raised. As a result, the holding piece is separated from the upper side of the electric device placed on the stand main body, so that the holding of the electric device is automatically released. In addition, since the electric device is pushed up by the mounting table, the user can easily remove the electric device from the stand device.

In the third invention, the apparatus further includes a device-side connector, a printed circuit board, and a vertical movement prevention unit.
The user places the electric device on the mounting table so that the device-side connector of the electric device is connected to the apparatus-side connector.
The device-side connector is mounted on a printed circuit board, and the printed circuit board is connected to a mounting table. For this reason, as the mounting table moves up and down, the printed circuit board and the apparatus-side connector also move up and down.
However, the vertical movement prevention unit prevents the mounting table from moving up and down before the connectors are connected, so that the mounting table is unnecessarily lowered before the connectors are connected and the connection between the connectors is poor. It is prevented from occurring. In addition, the vertical movement prevention unit prevents vertical vibration of the mounting table due to, for example, transmission of vehicle vibration to the stand device when no electrical device is mounted.

By the way, the printed circuit board can move in the substrate surface direction (that is, the direction along the surface of the printed circuit board) with respect to the mounting table. Therefore, even if the connector is misaligned during connection, The printed circuit board on which the device-side connector is mounted is moved by the external force applied. Therefore, the positional deviation between the connectors is automatically corrected.
As a result, the connectors are reliably connected without applying unnecessary external force to the device-side connector and / or the printed circuit board.

  In the fourth aspect of the invention, the vertical movement preventing portion provided so as to be detachable with respect to the mounting table is locked to the mounting table at the position where the mounting table is raised, thereby fixing the mounting table. That is, when an electrical device is not placed on the mounting table, the vertical movement prevention unit prevents the mounting table from moving up and down.

On the other hand, when the vertical movement preventing unit is pressed by the electric device mounted on the mounting table, the lock on the mounting table is released. However, the device-side connector is arranged so as to be connected to the device-side connector of the electric device mounted on the mounting table before the vertical movement preventing portion is unlocked. In other words, the connectors are connected before the electrical device is completely placed on the mounting table, and after the connectors are connected, the electrical device presses the vertical movement preventing portion and the vertical movement preventing portion and the mounting table. When the locking is released and the electric device further presses the mounting table, the mounting table is lowered and engaged with the fixing portion. In this state, for example, when the user manually releases the engagement between the fixed portion and the mounting table, the mounting table is raised and locked to the vertical movement preventing unit.
As a result, it is possible to achieve both prevention of unnecessary vertical movement of the mounting table and automatic clamping / canceling release of the electric device by lowering / raising the mounting table with a simple configuration.

  In the case of the stand device according to the first aspect of the invention, since the electric device is held between the holding piece and the stand body, it is ensured that the electric device is dropped from the stand device even if, for example, a vehicle shake is transmitted to the stand device. Can be prevented. Moreover, since it is not necessary to fix the electric device to the stand body using, for example, screws and screw holes, the user can easily attach and detach the electric device to and from the stand device.

In the case of the stand device according to the second aspect of the invention, when the user presses the mounting table with the electric device, the mounting table is lowered, and the contact / separation mechanism operates in a direction to bring the holding piece closer to the electric device. Can be pinched. At this time, useless raising of the mounting table can be prevented by the fixing portion.
Further, for example, when the user manually releases the engagement of the fixed portion, the elastic member raises the mounting table to the position where the mounting table is raised, and the contact / separation mechanism separates the holding piece from the electric device. Since it operates, it is possible to automatically release the electric device. At this time, the electric device can be raised from the position supported by the stand device.
As a result, the user can more easily attach and detach the electric device to and from the stand device.

In the case of the stand device of the third invention, unnecessary lowering of the mounting table is prevented when the connectors are connected, and the positional displacement between the connectors can be corrected by the movement of the printed circuit board. Can be connected to. In addition, when the electrical device is not placed, the placement table is prevented from moving up and down, so that it is possible to prevent the occurrence of noise due to rattling of the placement table.
Furthermore, it is possible to prevent unnecessary external force from being applied to the device-side connector and the printed circuit board due to the positional deviation between the connectors, and the device-side connector and the printed circuit board are deformed or damaged by such external force. Can be prevented. In addition, it is not necessary to use a floating type connector for this purpose, nor is it necessary to use a special connector having a flange formed on the outer periphery.

  In the case of the stand device according to the fourth aspect of the invention, it is possible to achieve both prevention of unnecessary vertical movement of the mounting table and automatic clamping / canceling release of the electric device due to the lowering / raising of the mounting table with a simple configuration. it can. In addition, since the electric device is automatically clamped / unclamped, the electric device can be easily attached and detached, and since the mounting table does not descend unnecessarily, the connectors can be securely connected to each other. Since it does not move up and down unnecessarily, vibration noise of the mounting table can be suppressed.

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.

Embodiment 1.
FIG. 1 is a perspective view schematically showing the appearance of a stand device according to Embodiment 1 of the present invention.
FIG. 2 is a side view for explaining a state in which no electrical device is placed on the stand device according to Embodiment 1 of the present invention, and FIG. 3 is a stand device according to Embodiment 1 of the present invention. It is a side view explaining the state by which the electric equipment was mounted.
Further, FIG. 4 is a front view of the vicinity of the device-side connector for explaining a state in which the electric device is being placed on the stand device according to Embodiment 1 of the present invention, and FIG. 5 is a diagram of the embodiment of the present invention. 2 is a front view of the vicinity of a device-side connector for explaining a state in which an electric device is placed on the stand device according to No. 1.

In the figure, reference numeral 1 denotes a stand device. FIG. 1 shows the back side of the stand device 1.
As shown in FIG. 1, the stand device 1 has a leg portion 1 a, and is bonded and fixed to a dashboard inside the vehicle by sticking, for example, a double-sided tape to the bottom surface of the leg portion 1 a. Moreover, the stand apparatus 1 is provided with a connector (not shown), and this connector is connected to a connector (not shown) provided in the vehicle. These connectors are for connecting the stand device 1 to an in-vehicle power source and an in-vehicle device (not shown).
In such a state, the stand device 1 supports the electric device 2 in a detachable manner.

  The electric device 2 is, for example, a portable navigation device, a television device, or the like. The electric device 2 has a thin rectangular box-like appearance, and a power button 2a for turning on / off the electric device 2 is provided on the left side of the top surface. A display surface on which an image such as a map to be guided and an image of a television program is displayed and an operation button for the user to operate the electric device 2 are arranged in parallel (each not shown).

The stand device 1 includes a stand main body 3 on which the electric device 2 is placed, a clamping member 4 formed in an inverted L shape in a side view, and a contact / separation mechanism 5.
The stand body 3 is formed in a box shape having an opening 3 a in the upper part, and the electric device 2 is inserted into and removed from the stand body 3 through the opening 3 a.
The clamping member 4 is provided with a clamping piece 41 at one end, and a clamping piece support portion 42 that supports the clamping piece 41. More specifically, the sandwiching member 4 according to the present embodiment is formed by integrally forming sandwiching pieces 41 and sandwiching piece support portions 42 each having a rectangular flat plate arranged substantially orthogonal to each other. Engaging protrusions 411 protrude from the inner surface (see FIGS. 2 and 3 to be described later). The end portion of the holding piece support portion 42 is rotatably supported by the contact / separation mechanism 5 so that the engaging protrusion 411 of the holding piece 41 faces the stand main body 3 side.

  The contact / separation mechanism 5 is disposed on the back of the stand body 3 and is configured to bring the holding piece 41 into and out of contact with the holding position of the electric device 2. The contact / separation mechanism 5 brings the holding piece 41 close to the holding position of the electric device 2, whereby the electric device 2 placed on the stand body 3 is held between the holding piece and the stand body 3. Further, when the contact / separation mechanism 5 separates the holding piece 41 from the holding position of the electric device 2, the holding piece 41 is separated from the upper side of the electric device 2 placed on the stand body 3. Is released. As a result, the electric device 2 can be taken out from the stand body 3.

  As shown in FIGS. 2 to 5, the stand body 3 includes a back surface portion 30, a mounting table 31, a fixing portion 32, an elastic member 33, a bottom surface portion 34, left and right side wall portions 35 and 35, and a front portion not shown. . However, illustration of the side wall portions 35 and 35 is omitted in FIGS. 2 and 3, and illustration of the fixing portion 32 and the right side wall portion 35 is omitted in FIGS. 4 and 5.

The mounting table 31 has a flat plate shape, on which the electric device 2 is mounted. The mounting table 31 is configured such that its peripheral portion can be moved up and down while sliding on the inner surface of each of the front surface portion, the back surface portion 30 and the side wall portions 35 and 35 of the stand body 3, and the electric power mounted on the mounting table 31. It descends when pressed downward by the device 2.
The mounting table 31 on which the electrical device 2 is not mounted (see FIGS. 2 and 4) is a position where the electrical device 2 is mounted (see FIGS. 3 and 5) and the mounting table 31 is lowered (hereinafter referred to as a lowered position). It is placed higher than This position is a position where the mounting table 31 is raised from the lowered position, and is hereinafter referred to as a raised position.

The mounting table 31 is formed with an insertion hole 31a through which an elastic member support bar 331 described later is inserted. The elastic member support bar 331 protrudes from the bottom surface 34 in a direction orthogonal to the mounting table 31, and the inner surface of the insertion hole 31 a slides on the circumferential surface of the elastic member support bar 331 as the mounting table 31 moves up and down.
As shown in FIGS. 4 and 5, the mounting table 31 includes through holes 31b, 31b,... Through which suspension screws 142, 142,. A board arrangement hole 31c into which 12 is loosely fitted is formed.

  As shown in FIGS. 2 and 3, the fixing portion 32 is detachably provided on the mounting table 31 and engages with the mounting table 31 lowered to the lowered position to fix the mounting table 31. As shown in FIGS. 2 to 5, the elastic member 33 is disposed on the lower side of the mounting table 31 and is compressed by the lowered mounting table 31, and the engaging portion of the fixing portion 32 is disengaged. Thus, the mounting table 31 is raised to the raised position.

First, the fixing part 32 will be described (see FIGS. 2 and 3).
The fixing portion 32 includes an engaging portion 32a that engages with and disengages from the mounting table 31, an urging portion 32b that incorporates a mainspring spring (not shown), and an operation lever 32c that is pressed by a user.
The urging portion 32b has a rotating shaft arranged in the left-right direction (the direction orthogonal to the paper surface in FIGS. 2 and 3), and the engaging portion 32a and the operation lever 32c are moved in the direction indicated by the arrow B and the arrow in the drawing. It is supported so as to be rotatable in the direction opposite to the B direction. However, the urging portion 32b is fixedly supported on the bottom surface portion 34 by a support portion (not shown).
When the mounting table 31 is arranged at the raised position, the engaging portion 32a is not engaged with the mounting table 31 (see FIG. 2). More specifically, the engaging surface of the engaging portion 32 a is located below the mounting table 31.

The engaging portion 32 a rotates in the direction of arrow B in the figure so as to be away from the mounting table 31 by being pressed against the mounting table 31 that starts to descend from the raised position. For this reason, the engaging portion 32 a does not hinder the lowering of the mounting table 31. Further, when the engaging portion 32a rotates in the direction of arrow B in the figure, an external force is applied to the spring of the urging portion 32b.
When the mounting table 31 further descends and reaches the lowered position, the engaging portion 32a is urged in the direction opposite to the arrow B direction in the drawing and rotated by the elastic restoring force of the urging portion 32b. As a result, the engaging surface of the engaging portion 32a engages with the upper surface of the end portion of the mounting table 31 (see FIG. 3), thereby preventing unnecessary lifting of the mounting table 31 (that is, fixing the mounting table 31).

When the user presses the operation lever 32c in the direction indicated by the arrow B in the figure while the engaging portion 32a is engaged with the mounting table 31, the engaging portion 32a is moved in the direction indicated by the arrow B so as to move away from the mounting table 31. Rotate to. For this reason, engagement with the engaging part 32a and the mounting base 31 is cancelled | released, and the mounting base 31 starts a raise. Further, when the engaging portion 32a rotates in the arrow B direction, an external force is applied to the spring of the urging portion 32b.
When the user releases the operation lever 32c after the mounting table 31 is further lifted and reaches the raised position, the engaging portion 32a is reversed in the direction indicated by the arrow B in the figure by the elastic restoring force of the urging portion 32b. It is urged in the direction and rotates. As a result, the engaging portion 32a returns to a state where it is not engaged with the mounting table 31 (see FIG. 2).

Next, the elastic member 33 will be described (see FIGS. 2 to 5).
The elastic member 33 uses a coil spring and is supported by an elastic member support bar 331 that penetrates the central portion of the elastic member 33.
When the mounting table 31 is lowered, the elastic member 33 is compressed between the lower surface of the mounting table 31 and the upper surface of the bottom surface part 34 (see FIGS. 3 and 5).
On the other hand, the elastic member 33 raises the mounting table 31 on which the electric device 2 is mounted to the raised position by an elastic restoring force (see FIGS. 2 and 4). That is, the elastic member 33 is hardly compressed when only the weight of the electric device 2 is applied to the mounting table 31, so that the user who mounts the electric device 2 can move the mounting table 31 down. 2, the mounting table 31 needs to be pressed with a force equal to or greater than the elastic restoring force of the elastic member 33.

  In addition, it is desirable that the plurality of elastic members 33, 33,... Are appropriately disposed (for example, at both the left and right ends of the mounting table 31) so that the mounting table 31 moves up and down uniformly.

As shown in FIGS. 3 to 5, an insertion hole 22 into which the elastic member support bar 331 of the stand device 1 is removably inserted is formed on the bottom surface of the electric device 2. In addition, an engagement hole (not shown) that engages and disengages the engagement protrusion 411 of the stand device 1 is formed at the center in the left-right direction of the top surface of the electric device 2.
Furthermore, a device-side connector 21 is provided at the left end of the bottom surface of the electric device 2. Furthermore, alignment holes 23 and 23 into which alignment pins 143 and 143, which will be described later, are removably inserted, are formed in the vicinity of the device-side connector 21 on the bottom surface of the electric device 2.

As shown in FIGS. 4 and 5, an apparatus-side connector 11, a printed circuit board 12, and a vertical movement prevention unit 13 are disposed inside the stand body 3.
The device-side connector 11 is mounted on the upper surface of the printed circuit board 12 and connected to the device-side connector 21 included in the electric device 2 placed on the placement table 31. The printed circuit board 12 is connected to the mounting table 31 so as to be movable in the substrate surface direction with respect to the mounting table 31. The vertical movement prevention unit 13 prevents the mounting table 31 from moving up and down before the device-side connector 21 and the apparatus-side connector 11 are connected.

First, the printed circuit board 12 will be described.
The printed circuit board 12 is arranged in the substrate placement hole 31c so that the upper surface on which the apparatus-side connector 11 is mounted and the upper surface of the mounting table 31 (that is, the mounting surface on which the electric device 2 is mounted) are positioned on the same surface. Are supported by the substrate support plate 141. The shape of the board arrangement hole 31 c corresponds to the shape of the printed circuit board 12, but the size of the board arrangement hole 31 c is appropriately longer than the size of the printed board 12.

  The substrate support plate 141 has a shape that is obtained by bending a single flat plate. The flat plate central portion 14a has the same shape and shape as the printed circuit board 12, and protrudes downward from the left and right end portions of the central portion 14a. Left and right suspension plate portions 14b, 14b projecting left and right from the lower end of the leg portion so as to be parallel to the central portion 14a and not to face the central portion 14a Have

The suspension plate portions 14 b and 14 b of the substrate support plate 141 are disposed below the mounting table 31. Here, the legs of the suspension screws 142, 142,... Pass through the through holes 31b, 31b,... Of the mounting table 31 with play, and the heads of the suspension screws 142 are mounted. The top surface of the mounting table 31 is locked. Further, the leg portions of the suspension screws 142, 142,... Are screwed and fixed into screw holes formed in the suspension plate portions 14b, 14b.
The leg portions of the suspension screws 142, 142,... Pass through between the upper surfaces of the suspension plate portions 14b, 14b of the substrate support plate 141 and the lower surface of the mounting table 31, and the bushes 144, 144 made of synthetic rubber. , ... are arranged.

That is, the substrate support plate 141 is suspended from the mounting table 31 via the suspension screws 142, 142,. Here, the suspension screws 142, 142,... Are movable in the upper surface direction (for example, the front-rear direction or the left-right direction) of the mounting table 31 in the through holes 31b, 31b,. . Moreover, since the bushes 144, 144,... Have elasticity, the suspension screws 142, 142,... Can move in the upper surface direction of the mounting table 31 while expanding and contracting the bushes 144, 144,. Therefore, the printed circuit board 12 supported by the substrate support plate 141 is connected to the mounting table 31 so as to be movable in the substrate surface direction with respect to the mounting table 31.
In the vicinity of the left side and the right side of the device-side connector 21, alignment pins 143 and 143 that protrude through the printed circuit board 12 from the upper surface of the central portion 14 a of the board support plate 141 are arranged.

  A printed circuit board 15 connected to the printed circuit board 12 by a harness on a film (not shown) is disposed on the upper surface of the bottom surface portion 34, and a leaf spring 16 is interposed between the printed circuit board 15 and the substrate support plate 141. It is arranged.

  The leaf spring 16 is compressed by the substrate support plate 141 lowered together with the mounting table 31, restored by the engagement portion of the fixed portion 32 being disengaged, and lifted up the mounting table 31 via the substrate support plate 141. It functions as an elastic member. Further, it is possible to prevent the substrate support plate 141 that has been lowered excessively from coming into contact with the printed circuit board 15 to cause deformation or damage of the printed circuit board 15. Further, since the compressed leaf spring 16 pushes up the board support plate 141 from the lower side, and thus the apparatus side connector 11 mounted on the printed circuit board 12, the apparatus side connector 11 and the apparatus side connector 21 (hereinafter referred to as the connector 11). , 21) are more securely connected. However, since the bushes 144, 144,... Are interposed between the mounting table 31 and the substrate support plate 141, an unnecessary external force is applied to the apparatus-side connector 11 from below, so that the connectors 11, 21 and / or The printed circuit board 12 and the like are prevented from being deformed or damaged.

Next, the vertical movement preventing unit 13 will be described.
The vertical movement prevention unit 13 is provided so as to be detachable with respect to the mounting table 31. The mounting table 31 is locked to the mounting table 31 at a position where the mounting table 31 is raised, and is mounted on the mounting table 31. When the electric device 2 is pressed, it is unlocked. For this purpose, the vertical movement preventing portion 13 includes a locking portion 131 and a spring portion 132.
The locking portion 131 is formed with a locking groove 13 a that engages and disengages with respect to the end of the mounting table 31 by inserting and removing the end of the mounting table 31. The spring part 132 uses a coil spring and is interposed between the locking part 131 and the left side wall part 35 (the right side in FIGS. 4 and 5) to support the locking part 131 so as to be movable in the left-right direction. is doing. It is desirable that the right side wall 35 is also provided with the vertical movement prevention unit 13 having the same configuration.

When the mounting table 31 is arranged at the raised position, the locking portion 131 is locked to the mounting table 31 (see FIG. 4). More specifically, the end of the mounting table 31 is inserted into the locking groove 13 a of the locking part 131. For this reason, even if a user presses the mounting base 31 directly by hand, the mounting base 31 does not fall.
The locking portion 131 is pressed in contact with the lower left corner of the electric device 2 inserted in the direction of the white arrow in FIG. Start moving to the right). For this reason, the latching | locking part 131 does not inhibit insertion of the electric equipment 2.

As the locking part 131 moves to the right, the end of the mounting table 31 gradually comes out of the locking groove 13a while compressing the spring part 132. However, since the device-side connector 11 of the stand device 1 is arranged to be connected to the device-side connector 21 of the electric device 2 before the locking between the vertical movement preventing unit 13 and the mounting table 31 is released, Until the connectors 11 and 21 are connected to each other, the end of the mounting table 31 does not completely come out of the locking groove 13a. For this reason, the mounting table 31 does not descend.
If the mounting table 31 starts to descend before the connectors 11 and 21 are connected, a connection failure may occur in the connectors 11 and 21. However, in the present embodiment, as described above, the vertical movement prevention unit 13 prevents the mounting table 31 from being lowered, so that the connectors 11 and 21 are reliably connected.

  When the connectors 11 and 21 are connected and the bottom surface of the electric device 2 is placed on the mounting table 31, the mounting table 31 is lowered to the lowered position by being pressed by the electric device 2 (see FIG. 5). At this time, the end portion of the mounting table 31 is completely removed from the locking groove 13a, and the locking between the vertical movement preventing unit 13 and the mounting table 31 is released. The vertical movement preventing portion 13 is disposed between the left side surface of the electric device 2 and the side wall portion 35, and the spring portion 132 is compressed between the locking portion 131 and the side wall portion 35.

After the engagement between the engaging portion 32a of the fixing portion 32 and the mounting table 31 is released and the mounting table 31 rises to the ascending position, the electrical device 2 is reversed from the opening 3a in the direction of the white arrow in FIG. When pulled out in the direction, the locking portion 131 is urged rightward (leftward in the figure) so as to approach the mounting table 31 by the elastic restoring force of the spring portion 132. At this time, the end of the mounting table 31 is inserted into the locking groove 13a. That is, the locking part 131 is locked to the mounting table 31. As a result, the vertical movement preventing unit 13 prevents the mounting table 31 from moving up and down.
As described above, the mounting table 31 moves up and down when vertical movement is necessary, and is fixed in the vertical direction when vertical movement is unnecessary.

As shown in FIGS. 2 and 3, the contact / separation mechanism 5 is configured such that the holding piece 41 approaches the holding position of the electric device 2 as the mounting table 31 is lowered, and the holding piece 41 is moved as the mounting table 31 is raised. The clamping member 4 is rotated so as to be separated from the clamping position of the electric device 2. For this purpose, the contact / separation mechanism 5 includes a rotation support part 51, a pressing part 52, and a transmission part 53, which are arranged at the center part in the left-right direction of the back part 30.
The rotation support portion 51 is disposed on the outer surface side upper portion of the back surface portion 30, and the lower end portion of the holding piece support portion 42 of the holding member 4 can be rotated around a shaft portion 511 arranged in the left-right direction. To support.

  More specifically, the rotation support portion 51 has a cylindrical portion 512 that rotates about the shaft portion 511, and the clamping piece support portion 42 of the clamping member 4 is integrally formed on the peripheral surface of the cylindrical portion 512. The lower end is arranged. A rotating piece 513 protrudes from the lower end portion of the holding piece support portion 42 at a predetermined angle from the cylindrical portion 512. Therefore, the clamping member 4 and the rotating piece 513 are rotated in the directions of arrows A1 and A2 in the drawing around the shaft portion 511. In addition, the main body spring (not shown) is built in the cylindrical portion 512, and when the holding piece 41 is rotated in a direction approaching the holding position of the electric device 2 (that is, in the direction of arrow A2 in FIG. 3), the holding piece 41 Produces an elastic restoring force that rotates in a direction away from the clamping position of the electric device 2 (that is, in the direction of arrow A1 in FIG. 2).

  The pressing portion 52 is disposed at the center portion on the outer surface side of the back surface portion 30, and is compressed when the pressing rod 521 is moved upward, and the pressing rod 521 disposed so as to be movable up and down along the vertical direction. And a coil spring 522 for lowering the pressing rod 521. The upper end portion of the pressing rod 521 is disposed close to the rotating piece 513 of the rotation support portion 51, and when the pressing rod 521 rises, the pressing rod 521 presses the rotating piece 513, and the rotation support portion 51. Is rotated in the direction of arrow A2. Further, when the rotating piece 513 is rotated in the direction of the arrow A1 by the elastic restoring force of the cylindrical portion 512, the pressing rod 521 is pressed by the rotating piece 513 and descends.

  The transmission portion 53 is disposed through a hole (not shown) provided in the lower portion of the back surface portion 30 and has a seesaw shape that rotates around a shaft portion 531 disposed in the left-right direction. One end portion 532 of the seesaw-shaped transmission portion 53 is disposed close to the lower surface of the mounting table 31, and the other end portion 533 is disposed close to the lower end portion of the pressing rod 521. For this reason, the transmission part 53 is pressed downward by the pressing bar 521 or the mounting table 31 and rotates in the directions of the arrows C1 and C2 in the drawing to press the mounting table 31 or the pressing bar 521 upward.

The operation of the contact / separation mechanism 5 will be described below.
When the mounting table 31 is lowered from the raised position, in the transmission unit 53, the lower end of the mounting table 31 presses one end 532 to rotate in the direction of the arrow C2 in FIG. 3, and the other end 533 is a pressing rod 521. Is pressed upward. In the pressing portion 52, the pressing rod 521 pressed upward by the other end portion 533 presses the rotating piece 513, and the coil spring 522 is compressed.
In the rotation support portion 51, when the pressing rod 521 presses the rotation piece 513, the rotation support portion 51 rotates in the direction of the arrow A <b> 2, and an external force is applied to the cylinder portion 512. With the rotation of 51, the clamping piece 41 approaches the clamping position of the electric device 2. In other words, the clamping member 4 is closed to clamp the electric device 2 placed on the stand body 3.

On the other hand, when the mounting table 31 is lifted from the lowered position, in the transmission unit 53, the pressing of the one end 532 by the mounting table 31 is released. As a result, in the pressing part 52, the pressing of the pressing bar 521 by the other end 533 is released, and in the rotation support part 51, the pressing of the rotating piece 513 by the pressing bar 521 is released.
At this time, the rotation support portion 51 rotates in the direction of the arrow A1 in FIG. 2 by the elastic restoring force of the cylindrical portion 512 of the rotation support portion 51. As the rotation support portion 51 rotates, the clamping piece 41 is separated from the clamping position of the electric device 2. In other words, the clamping member 4 is opened to release the clamping of the electric device 2 placed on the stand body 3.

As the rotation support portion 51 rotates, the rotation piece 513 presses the pressing rod 521 of the pressing portion 52 downward. Pressed by the rotating piece 513, and by the elastic restoring force of the coil spring 522, the pressing bar 521 is lowered, the other end 533 of the transmitting portion 53 is pressed downward, and is rotated in the direction of the arrow C1. 532 presses the mounting table 31 upward.
As described above, the contacting / separating mechanism 5 brings the holding piece 41 into and out of contact with the holding position of the electric device 2 as the mounting table 31 moves up and down. Further, when the holding piece 41 is separated from the holding position of the electric device 2, the contact / separation mechanism 5 also has a function of raising the mounting table 31.

  When using the stand device 1 as described above, the user places the electric device 2 on the stand body 3 through the opening 3 a of the stand body 3. More specifically, the user causes the alignment pins 143 and 143 of the stand device 1 and the elastic member support bar 331 to be inserted into the alignment holes 23 and 23 and the insertion hole 22 of the electric device 2, respectively. Thus, the device-side connector 11 of the stand device 1 and the device-side connector 21 of the electric device 2 are aligned, and the electric device 2 is placed so that the device-side connector 21 is connected to the device-side connector 11. Placed on. At this time, the user presses the mounting table 31 downward using the electric device 2.

  Since the elastic member 33 is disposed on the lower side of the mounting table 31, the mounting table 31 is in a state of being separated from the bottom surface part 34 and descends when pressed downward by the electric device 2 to be mounted. The device-side connector 11 is mounted on a printed circuit board 12, and the printed circuit board 12 is connected to a mounting table 31. For this reason, as the mounting table 31 is lowered, the printed circuit board 12 and the apparatus-side connector 11 are also lowered.

However, since the vertical movement prevention unit 13 prevents the mounting table 31 from moving up and down before the connectors 11 and 21 are connected, the mounting table 31 is unnecessarily lowered before the connectors 11 and 21 are connected. This prevents the connection failure of the connectors 11 and 21.
In addition, the printed circuit board 12 can be moved in the direction of the substrate surface with respect to the mounting table 31 by the substrate support plate 141, the suspension screws 142, 142,..., The bushes 144, 144,. Therefore, even if the connectors 11 and 21 are misaligned during the connection, the printed circuit board 12 is moved by the external force applied to the device-side connector 21. Accordingly, the positional deviation of the connectors 11 and 21 is automatically corrected. As a result, the connectors 11 and 21 are securely connected without applying unnecessary external force to the device-side connector 11 and / or the printed circuit board 12 or the like.

  The elastic member 33 contracts when pressed by the lowered mounting table 31, and the engaging portion 32 a of the fixing portion 32 engages with the mounting table 31 at a position where the mounting table 31 is lowered to fix the mounting table 31. To do. The contact / separation mechanism 5 rotates the holding member 4 around the end of the holding piece support portion 42 so that the holding piece 41 approaches the holding position of the electric device 2 as the mounting table 31 is lowered. When the contact / separation mechanism 5 brings the holding piece 41 closer to the holding position of the electric device 2, the holding piece 41 is arranged on the upper side of the electric device 2 placed on the stand main body 3, and the engagement protrusion 411 is provided in the electric device. 2 Engage with the engagement holes on the top surface.

As a result, the clamping piece 41 clamps the electric device 2 with the stand body 3. In other words, the electrical device 2 is supported by the stand device 1 while being sandwiched between the upper sandwiching piece 41 and the lower stand body 3. For this reason, even if the motion of the vehicle is transmitted to the stand device 1, the electric device 2 does not drop from the stand device 1.
In addition, by the reliable connection of the connectors 11 and 21, power is reliably supplied to the electric device 2 mounted on the stand device 1 via the connectors 11 and 21, and between the electric device 2 and the in-vehicle device. Various signals are transmitted and received reliably.

Thereafter, when removing the electric device 2, the user manually releases the engagement between the engaging portion 32 a of the fixing portion 32 and the mounting table 31 by pressing the operation lever 32 c of the fixing portion 32. .
When the engagement between the fixing portion 32 and the mounting table 31 is released, the mounting table 31 is raised by the restoring force of the elastic member 33. As the mounting table 31 rises, the printed circuit board 12 and the device-side connector 11 also rise. The contact / separation mechanism 5 rotates the holding member 4 about the end of the holding piece support portion 42 so that the holding piece 41 is separated from the holding position of the electric device 2 as the mounting table 31 is raised. As a result, the clamping piece 41 is separated from the upper side of the electric device 2 placed on the stand body 3, and the engagement between the engagement protrusion 411 and the engagement hole on the top surface of the electric device 2 is released. 2 is automatically released. Moreover, it is pushed up by the mounting table 31 and the electric device 2 rises.

The user removes the electrical device 2 from the stand device 1 in a state where the clamping of the electrical device 2 is released.
By the way, when the electric equipment 2 is not placed, the up-and-down motion preventing unit 13 prevents up-and-down vibration (rattle) of the mounting table 31 due to, for example, transmission of vehicle vibration to the stand device 1. As a result, noise caused by the play of the mounting table 31 is suppressed.

Embodiment 2. FIG.
FIG. 6 is a side view illustrating a state in which no electrical device is placed on the stand device according to Embodiment 2 of the present invention. FIG. 7 is a side view for explaining a state where an electrical device is being placed on the stand device according to the second embodiment of the present invention, and FIG. 8 is a stand device according to the second embodiment of the present invention. It is a side view explaining the state by which the electric equipment was mounted. 6 to 8, reference numeral 38 denotes a front portion of the stand main body 3.
FIG. 9 is a perspective view showing the external appearance of the mounting table and a part of the contact / separation mechanism provided in the stand device according to Embodiment 2 of the present invention.

  The contact / separation mechanism 5 of the stand device 1 of the present embodiment is different in configuration from the contact / separation mechanism 5 of the stand device 1 of the first embodiment. The stand main body 3 of the present embodiment has a mounting table 36 instead of the mounting table 31 of the first embodiment, and has the same configuration as the fixing unit 32 instead of the fixing unit 32 that fixes the mounting table 31. The base plate 561 of the swing base 56, which will be described later, is provided so as to be able to be engaged and disengaged directly, and has a fixing portion (not shown) for fixing the mounting base 36 indirectly via the base plate portion 561. Instead of the elastic member 33 disposed on the lower side of the mounting table 31, the elastic member 57 is disposed on the lower side of the bottom plate portion 561 with the same configuration as the elastic member 33. The elastic member support bar 571 of the elastic member 57 is inserted through an insertion hole 56 b formed in the bottom plate portion 561. Furthermore, a device-side connector (not shown) is disposed on the stand body 3 and is connected to a device-side connector (not shown) of the electric device 2 placed on the stand body 3.

  Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The contact / separation mechanism 5 is housed in the stand body 3 and is configured to bring the holding piece 41 into and out of contact with the holding position of the electric device 2. More specifically, in the contact / separation mechanism 5, the holding piece 41 approaches the holding position of the electric device 2 as the mounting table 36 is lowered, and the holding piece 41 holds the electric device 2 as the mounting table 36 is raised. The clamping member 4 is rotated so as to be separated from the position. For this purpose, the contact / separation mechanism 5 includes a sliding portion 54, a rotation coupling portion 55, a swing base 56, and an elastic member 57, which are arranged at the center in the left-right direction of the back surface portion 30.

The oscillating base 56 is a plate-like member having an L-shape in side view in which a bottom plate portion 561 and a back plate portion 562 arranged orthogonal to the bottom plate portion 561 are integrally formed. An insertion hole 56a through which a mounting table support plate 361 described later is inserted is formed from the bent portion to the center portion in the front-rear direction of the bottom plate portion 561. As will be described later, such a swinging table 56 swings up and down as the mounting table 36 moves up and down.
The elastic member 57 is disposed on the lower side of the bottom plate portion 561 of the swing base 56, is compressed by the lowered bottom plate portion 561, and is restored by disengaging the fixing portion (not shown) to restore the bottom plate portion 561. To raise.

The rotation coupling portion 55 is disposed at the upper end portion of the back plate portion 562 of the swing base 56, and the shaft portion 551 is disposed at the lower end portion of the clamping piece support portion 42 of the clamping member 4 in the left-right direction. It is supported so as to be rotatable around the center.
More specifically, the rotation coupling portion 55 is configured to couple the clamping piece support portion 42 of the clamping member 4 and the back plate portion 562 of the swing base 56 in a hinge shape, and rotate about the shaft portion 551. A cylindrical portion 552 is provided. Further, the main body spring (not shown) is incorporated in the cylindrical portion 552, and is clamped when the clamping piece 41 is rotated in a direction approaching the clamping position of the electric device 2 (that is, the arrow A2 direction shown in FIG. 7). An elastic restoring force that causes the piece 41 to rotate in a direction away from the holding position of the electric device 2 (that is, the direction of the arrow A1 shown in FIG. 6) is generated.

  The sliding portion 54 has a convex shape projecting from the back surface of the sandwiching piece support portion 42 of the sandwiching member 4, and slides on the upper end portion and the inner surface of the back surface portion 30, as shown in FIG. 6. Thus, the rotation of the clamping member 4 between the position where the clamping piece support part 42 is tilted backward and the position where the clamping piece support part 42 is upright as shown in FIGS. 7 and 8 is guided.

  The mounting table support plate 361 has an inverted V shape that is T-shaped in a plan view and shallow in a side view. The mounting table 36 has a trapezoidal shape integrally projecting on the upper surface in the vicinity of the base end portion of the mounting table support plate 361, and is pressed downward by the electric device 2 mounted on the mounting table 36. If you go down. For this purpose, a rotation shaft portion 362 disposed in the left-right direction is integrally provided at the base end portion of the mounting table support plate 361, and the mounting table support plate 361 is centered on the rotation shaft portion 362. The mounting table 36 is configured to be vertically movable by rotating. Further, the mounting table support plate 361 is inserted into the insertion hole 56a of the swing table 56, the front end portion is disposed close to the upper surface of the bottom plate portion 561 of the swing table 56, and the rotation shaft portion 362 is the back surface portion. 30.

  Accordingly, the mounting table support plate 361 and the swinging table 56 are raised or lowered in conjunction with each other. When the swinging table 56 is arranged at the raised position (see FIG. 6), the mounting table support plate 361 is provided on the mounting table support plate 361. The mounting table 36 is disposed at the raised position, and as the swinging table 56 is lowered (see FIG. 7), the mounting table 36 is also lowered, and the swinging table 56 is disposed at the lowered position. When engaged by the fixing portion (see FIG. 8), the mounting table 36 is arranged at the lowered position and fixed. That is, the fixing portion (not shown) is indirectly engaged with the mounting table 36 via the swinging table 56 at the lowered position to fix the mounting table 36. However, since the mounting table support plate 361 can move minutely up and down with respect to the swing table 56 within the opening range of the insertion hole 56a, the mounting table support plate 361 is indirectly engaged and fixed to the fixing portion (not shown). The mounting table 36 is capable of minute relative vertical movement with respect to the swinging table 56.

  Further, the rotation shaft portion 362 of the mounting table support plate 361 is provided with a helical spring (not shown), and the mounting table support plate 361 rotates in the direction in which the mounting table 36 descends (the direction of arrow D in FIG. 7). In this case, an elastic restoring force that rotates the mounting table support plate 361 in the direction in which the mounting table 36 ascends (the direction opposite to the arrow D direction in FIG. 7) is generated. That is, the mounting table support plate 361 and the rotation shaft portion 362 are arranged below the mounting table 36, are compressed by the lowered mounting table 36, and are restored by disengaging the fixing unit (not shown). And it functions also as an elastic member which raises the mounting base 36 to the position where the mounting base 36 rose.

When the stand device 1 as described above is used, the electric device 2 is placed on the stand body 3. More specifically, the user places the electric device 2 on the mounting table 36 while the elastic member support bar 571 of the stand device 1 is inserted into the insertion hole 22 of the electric device 2. At this time, the user presses the mounting table 36 downward using the electric device 2.
When the mounting table 36 is pressed downward, the mounting table support plate 361 rotates in the direction of arrow D in FIG.

  When the swinging table 56 is lowered, the elastic member 57 is compressed between the bottom plate portion 561 and the bottom surface portion 34, and on the back surface of the sandwiching piece support portion 42 disposed on the upper end portion of the back plate portion 562. When the projecting sliding portion 54 slides from the upper end portion of the back surface portion 30 to the inner surface, the clamping member 4 rotates in the direction of the arrow A2 while descending, and as a result, the clamping piece support portion 42 Stands upright and the clamping piece 41 approaches the clamping position of the electric device 2. However, the engaging protrusion 411 of the holding piece 41 does not engage with the electric device 2 while the user pushes in the electric device 2.

When the mounting table 36 is lowered to the lowered position (FIG. 8), the swinging table 56 and the mounting table 36 are fixed by the engagement of the fixing unit (not shown). At this time, when the user releases his / her hand from the electric device 2, the mounting table support plate 361 is slightly rotated in the direction opposite to the arrow D direction by the elastic restoring force of the rotating shaft portion 362. The device 2 is pushed up slightly, and the engagement protrusion 411 is engaged with the electric device 2.
As described above, the electric device 2 is firmly held between the holding piece 41 and the mounting table 36 by the engagement of the engaging protrusion 411 with the electric device 2 and the pushing-up of the electric device 2 by the mounting table 36. The For this reason, even if the motion of the vehicle is transmitted to the stand device 1, the electric device 2 does not drop from the stand device 1.

Thereafter, when the electric device 2 is removed, the user operates the fixing portion (not shown) to release the engagement of the fixing portion.
At this time, the rocking table 56 is raised by the elastic restoring force of the elastic member 57. Further, the mounting table support plate 361 rotates in the direction opposite to the arrow D direction by being pushed up by the rising rocking table 56 by the elastic restoring force of the rotating shaft part 362. For this reason, the mounting table 36 rises, and the electric device 2 mounted on the mounting table 36 rises.

Further, as the swinging table 56 is raised, the sliding portion 54 protruding from the back surface of the holding piece support portion 42 disposed at the upper end portion of the back plate portion 562 extends from the inner surface of the back surface portion 30 to the upper end portion. By sliding, the clamping member 4 is lifted and rotated in the direction of the arrow A1 shown in FIG. 6, and as a result, the clamping piece support part 42 is tilted rearward and the engagement of the engagement protrusion 411 is released. Then, the clamping piece 41 is separated from the clamping position of the electric device 2.
The user removes the electrical device 2 from the stand device 1 in a state where the clamping of the electrical device 2 is released.

  Since the stand device 1 as described above has fewer parts of the contact / separation mechanism 5 than the stand device 1 of the first embodiment and has a simple configuration, the stand device 1 can be manufactured at low cost, and the failure of the contact / separation mechanism 5 is also possible. High reliability because it is difficult to occur.

Embodiment 3. FIG.
FIG. 10 is a front view of the vicinity of the device-side connector for explaining a state in which an electric device is being placed on the stand device according to the third embodiment.
11 and 12 are a plan view and a side view of the vicinity of the device-side connector provided in the stand device according to the third embodiment.
In the present embodiment, unlike the first embodiment, a configuration in which the printed circuit board 12 on which the apparatus-side connector 11 is mounted is coupled to the bottom surface portion 34 so as to be movable in the substrate surface direction with respect to the bottom surface portion 34 is illustrated. To do.
The x-axis direction, the y-axis direction, and the z-axis direction shown in FIGS. 10 to 12 are directions along the left-right direction, the front-rear direction, and the up-down direction of the stand device of the present embodiment.

Further, as shown in FIG. 10, the alignment pins 143 and 143 protrude from the upper surface of the printed circuit board 12. However, a flat plate for supporting the substrate is arranged on the lower side of the printed circuit board 12, and printing is performed from the upper surface of the flat plate. The structure which penetrates the board | substrate 12 and protrudes may be sufficient.
Furthermore, as shown in FIGS. 10 to 12, the leaf spring 16 is arranged in a bridge shape symmetrical in both the x-axis direction and the y-axis direction over the opening peripheral front part and the opening peripheral rear part of the rectangular hole 34 a described later. ing.

A rectangular hole 34 a is formed in the bottom surface portion 34. The dimensions in the left-right direction and the front-rear direction of the opening of the rectangular hole 34 a are longer than the corresponding dimensions of the printed circuit board 12. The printed circuit board 12 is arranged so as to be movable in the left-right direction, the front-rear direction, and the up-down direction above the opening of the rectangular hole 34a.
For this purpose, the printed circuit board 12 has the left end in FIGS. 10 and 11 connected to the left edge of the opening edge of the rectangular hole 34a by three leaf springs 171, 173, 175, and the right end is a rectangular hole. The leaf springs 172, 174, and 176 are connected to the right side of the opening peripheral edge of 34a, and the lower surface is disposed close to the upper surface of the central portion of the leaf spring 16. Here, the elastic coefficient of the leaf springs 171 to 176 is smaller than that of the leaf spring 16 (that is, the spring force is light).

Each of the leaf springs 171 to 176 has a deformed Z shape, and the bent portion functions like a hinge. Therefore, each of the leaf springs 171 to 176 is compressed when the bent portion is further bent, and is expanded when the bent portion is extended in a flat plate shape.
The leaf springs 171 to 176 and the printed circuit board 12 are arranged in a bridge shape that is symmetrical in the x-axis direction and the y-axis direction, respectively, across the opening peripheral left part and the opening peripheral right part of the rectangular hole 34a.

More specifically, the leaf springs 171 and 172 are disposed in a direction facing the bottom surface portion 34, and the leaf springs 173 to 176 are disposed in a direction orthogonal to the bottom surface portion 34. More specifically, one end of the leaf spring 171 (or leaf spring 172) is fixed to the left edge of the opening edge (or right edge of the opening edge) of the rectangular hole 34a, for example, with a screw, and the other end is One end of each of the leaf springs 173 and 175 (or the leaf springs 174 and 176) is fixed. The other end portions of the leaf springs 173 and 175 (or leaf springs 174 and 176) are fixed to the left end portion (or right end portion) of the printed circuit board 12.
The device-side connector 11 and the printed circuit board 12 move in the z-axis direction by the expansion and contraction of the left and right leaf springs 171 and 172.

  When such a stand device is used, the user inserts the alignment pins 143 and 143 of the stand device into the alignment holes 23 and 23 of the electric device 2, respectively. The side connector 11 and the equipment side connector 21 of the electrical equipment 2 are aligned, and the equipment side connector 21 is placed on the stand device so as to be connected to the equipment side connector 11. At this time, the electrical device 2 presses the device-side connector 11 and the printed board 12 downward.

  The printed circuit board 12 pressed downward by the electric device 2 descends and presses the leaf spring 16 downward. At this time, since the elastic restoring force of the leaf spring 16 presses the printed circuit board 12 upward, the printed circuit board 12 and, consequently, the apparatus-side connector 11 is lowered unnecessarily, resulting in poor connection in the connectors 11 and 21. To prevent. Even if a large downward external force is applied to the device-side connector 11 and the printed circuit board 12, the leaf spring 16 absorbs this external force, so that the device-side connector 11 and the printed circuit board 12 are deformed or damaged. Etc. are prevented.

By the way, if a displacement in the x-axis direction occurs between the connectors 11 and 21 to be connected, the left leaf springs 173 and 175 expand (or are compressed) in the x-axis direction, and the right leaf springs 174 and 176 Is compressed (or expanded) in the x-axis direction, so that the apparatus-side connector 11 and the printed circuit board 12 move in the x-axis direction, so that the positional deviation in the x-axis direction is corrected.
Further, if a displacement in the y-axis direction occurs between the connectors 11 and 21 to be connected, the front leaf springs 173 and 174 extend (or are compressed) in the y-axis direction, and the rear leaf springs 175 and 175 are compressed. Since the apparatus-side connector 11 and the printed circuit board 12 move in the y-axis direction when the 176 is compressed (or expanded) in the x-axis direction, the positional deviation in the y-axis direction is corrected.

  Other parts corresponding to those of the first and second embodiments are denoted by the same reference numerals, and description thereof is omitted.

  Even in the configuration as described above, the printed circuit board 12 on which the device-side connector 11 is mounted is moved by an external force applied to the device-side connector 11, so that the misalignment of the connectors 11 and 21 at the time of connection is automatically corrected. Is done. As a result, deformation, breakage, and the like of the device-side connector 11 and the printed circuit board 12 are prevented.
