Further, the front lanyard 124 includes a first handle contact portion 125 and a second handle contact portion 126.

As shown in FIG. 13, the circuit board 110 is provided with a board connector 115 at the rear end on the right side in the figure. A front panel 111 is provided at the front end on the left side of the circuit board 110 in the drawing, and a pair of upper and lower handlebars 110 are provided on the upper and lower sides of the front panel 111, respectively. 0, 100 are provided. As shown in FIG. 14 (A), each of the insertion / extraction handles 100 is detachably engaged with a handle engagement portion 112 provided on the circuit board 110 at the rear end side. The first handle contact portion 1 2 5 and the second handle contact portion 1 26 of the front rail 1 24 of the subrack 120 The contacted portion 103 having the contacted portion 103a and the second contacted portion 103b, the locked portion 102, and the contacted portion A rotary shaft portion 104 is attached to the handle mounting member 140 provided on the circuit board 110 between the rotary shaft portion 104 and the rotary shaft portion 104. At the front end side of the insertion / extraction handle 100, a pressing operation unit 101 having a first pressing operation unit 101a and a second pressing operation unit 101b is provided.

When the circuit board 110 is to be inserted into the subrack 120, the locked portion 102 of the insertion / removal handle 100 is removed from the handle locking portion 112 as shown in FIG. 14 (B). From that state, insert the circuit board 110 into the subrack 120 and press the first pressing operation part 101a of the handle 100 for insertion and removal upward (in the direction of arrow 65) in FIG. 14B. Manipulate. As a result, the handle 100 for insertion and removal rotates around the rotation shaft portion 104 as the center of rotation, and the first contact portion 103 a of the handle 100 for removal and the front The first handle abutment portion 125 abuts. Further, when the pulling handle 100 is rotated, the first abutted portion 103 a rotates, whereby the circuit board 110 moves rearward (X direction in the drawing) with respect to the subrack 120. Then, the board side connector 115 of the circuit board 110 is inserted into the subrack side connector 123 provided in the subrack 120 (see FIG. 6). Also, in this state, the locked portion 102 of the insertion handle 100 is locked to the handle locking portion 112 as shown in FIG.

In FIG. 13 in this locked state, for example, when the pressing operation portion 101 of the insertion / extraction handle 100 projects between the upper and lower handle locking portions 112, 112 of the circuit board 110, the circuit board 1 When using the front panel 1 10 by drilling holes in the LED and arranging the LEDs, the handle for insertion and removal 100 will be in the way, and use the front part of the circuit board 110. The possible range becomes narrow. In addition, at the International Electrotechnical Commission (IEC), etc., the handle 100 for insertion / extraction protrudes from the portion of the circuit board 110 between the approximately 1 1 2 and 1 1 2 on the front panel 1 1. It is standardized so that it does not.

Therefore, the conventional handle 100 for insertion / extraction has the front panel 1 1 1 1 of the circuit board 110 with the locked portion 102 of the handle 100 for insertion / extraction locked to the handle locking portion 112. From the front.

On the other hand, remove the circuit board 1 10 inserted into the subrack 120 from the subrack 120. In this case, from the state shown in FIG. 14 (A), move the second pressing operation portion 101 b of the insertion / removal handle 100 on the side opposite to the pressing direction of the first pressing operation portion 101 a.

As a result, as shown in FIG. 14 (B), the locked portion 102 is unlocked from the handle locking portion 112, and the second contact portion of the pull-out handle 100 is released. 10 3 b and the second handle contact portion 1 2 6 of the front rail 1 2 4 of the subrack 1 2 0 abut, and when the handle for insertion and removal 100 is further rotated, the second contact portion 1 0 3 b is rotated, whereby the circuit board 110 is moved to the left front side (Y direction in the drawing) with respect to the subrack 120, and the board side of the circuit board 110 is moved. The connector 115 can be disconnected from the subrack side connector 123 of the subrack 120.

However, if the conventional handle 100 for insertion and removal is made of a material having a short length, when the pressing operation unit 103 is operated to pull out the circuit board 110 from the subrack 120 In view of the fact that a large force has to be applied to the pressing operation portion 103, it is configured with a long length. Therefore, with the circuit board 110 inserted into the subrack 120, the handle 100 for insertion and removal projects from the front panel 111 of the circuit board 110 by a considerable length, and the subrack 120 Even after being stored in the sub rack, it protrudes from the sub rack 12 ° by a considerable length. As a result, when the sub-rack 120 containing the circuit board 110 is installed, the handle 100 for removal becomes a hindrance, requiring a large installation space, and the handle 100 for insertion and removal. There is a problem that other objects are easy to hit. Disclosure of the invention

If the handle piece 2 is rotated about the rotation axis 34 for the support section before the rotation about the rotation axis 21 for the handle piece, the first abutting section 3 1 and the first handle contact portion 125 of the Supraq 120 come into contact with each other. Then, a load is applied to the first contacted portion 31 by the contact, so that the first contacted portion 31 maintains the state, and the handle piece 2 is connected to the handle piece rotating shaft 21. Rotating around the center of rotation, the regulation contact portion 22 of the handle piece 2 and the first regulation portion 36a of the handle support portion 3 come into contact with each other, resulting in the state shown in FIG.

When the first pressing operation portion 23 of the handle piece 2 is further pressed in the direction of arrow 62 from the state shown in FIG. 8, the handle piece 2 is turned with the support portion rotation shaft 34 as the rotation shaft. It rotates together with the support 3 with respect to the substrate body 110a. In addition, with the rotation, the first contacted part 31 that abuts on the first handle contact part 125 of the subrack 120 rotates, and the substrate body 110a is rotated. Move relatively forward. Then, during the movement, the substrate main body 110a is positioned rearward with respect to the subrack 120 (see FIG. (X direction of 8).

As a result, as shown in FIG. 9, the board side connector 1 15 of the board body 110 a is fitted into the sub rack side connector 123 of the sub rack 120, and the handle piece 2 is locked. The part 25 is locked to the handle locking part 112 of the substrate body 110a. Next, when removing the substrate main body 110a from the subrack 120, the locking release operation part 26 of the handle piece 2 is pressed in the direction of arrow 63 from the state shown in FIG. As a result, the locked portion 25 of the handle piece 2 can be unlocked from the handle locking portion 112 of the substrate body 110a as shown in FIG.

When the locked portion 25 of the handle piece 2 and the handle locking portion 1 12 of the substrate body 110a are released, the handle piece 2 is locked by the urging force of the urging member 5. The locking portion 25 rotates together with the handle supporting portion 3 in a direction away from the handle locking portion 1 1 2 of the substrate body 110 a with the rotation shaft 34 for the support portion as the axis of rotation, and the handle. The one-sided rotation shaft 21 is rotated in the same direction with respect to the handle support 3 using the rotation shaft as the rotation axis.

In addition, as the handle piece 2 rotates about the support portion rotation shaft 34 as a rotation axis, as shown in FIG. 11, the second contact portion 32 and the subrack 120 (2) Handle contact portion 1 2 6 contacts. In addition, as the handle piece rotating shaft 21 rotates about the rotation axis, the restricting contact portion 22 of the handle piece 2 and the first restricting portion 36a of the handle support portion 3 come into contact with each other. In this state, a finger is inserted between the second pressing operation part 24 of the handle piece 2 and the handle locking part 112 of the substrate body 110a to insert the second pressing operation part 2 The finger insertion portion 6 is formed such that the finger 4 can be pressed. '

In this state, a finger is inserted into the finger insertion section 6 and the second pressing operation section 24 is pressed in the direction opposite to the pressing direction of the first pressing operation section 23 (arrow 64 direction). As a result, the handle piece 2 rotates with respect to the substrate main body 110a with the rotation shaft 34 for the support portion as the axis of rotation. Further, with the rotation, the second contacted portion 32 rotates, and moves relatively rearward with respect to the substrate main body 110a. Then, at the time of the movement, the substrate main body 110a is moved to the front side (Y direction in FIG. 11) with respect to the subrack 120.

As a result, the board-side connector 1 15 of the board body 110a is connected to the subrack 120 It can be disconnected from the subrack side connector 123 (as shown in Fig. 7). In this state, the handle piece 2 is located at substantially the same height as the tip of the second contact portion 32 of the handle support portion 3 as shown in FIG. It is almost the same height as 24a.

Therefore, for example, even when a plurality of sub-racks 120 are stacked and used, when rotating the handle piece 2 of the handle 1 for pulling out the circuit board 110 stored in one sub-rack 120, The circuit board 110 accommodated in the subrack 120 can be configured so as not to hit the other extraction handle 1. Thereby, the handle 1 can be smoothly rotated.

Then, in this state, the first pressing operation portion 23 and the second pressing operation portion 24 of the handle piece 2 are gripped and pulled forward. Thus, the circuit board 110 can be pulled out of the sub rack 120. At this time, since the distance between the first pressing operation portion 23 and the second pressing operation portion 24 gradually increases in the pulling direction, the hand is less likely to slip from the handle piece 2 and can be easily pulled.

In the above embodiment, the handle piece 2 and the handle support 3 are urged by one urging member 5. For example, the handle piece urging member and the handle support The handle member 2 is urged against the handle support 3 by the handle member urging member, and the handle support 3 is mounted on the substrate by the handle support urging member. A bias may be applied to the main body 110a.

Further, in the above embodiment, the front panel 111 is provided on the substrate body 110a, and the front end face of the substrate body 110a includes the front panel 111. It is not necessary to provide the panel 111, and it can be changed as appropriate.

Further, in the above embodiment, the handle piece 2 is moved from the position where the locked portion 25 is locked to the handle locking portion 112 in a state where the circuit board is inserted into the subrack 120. The rotation is performed in a range until the height is substantially the same as the upper and lower outer surfaces of the upper and lower outer surfaces. However, the present invention is not limited to this configuration. Range from the position where 1 and 2 are locked to an appropriate position inside the upper outer surface or lower outer surface of the subrack 120 with the circuit board inserted into the subrack 120, Alternatively, with the circuit board inserted into the subrack 120 from the position where the locked part 25 and the handle locking part 112 lock, from the upper outer surface or the lower outer surface of the sub rack 120 to the outside. A predetermined amount, specifically, when a plurality of subrackes 120 containing circuit boards 110 are stacked, a handle for inserting and removing a circuit board stored in one subrack 120 is replaced with another subrack 1. When the handle locking portion 1 1 2 and the locked portion 25 of the circuit board stored in 20 are locked, rotate the range up to the protruding position by an amount that does not hit the extraction handle. This may be done and can be changed as appropriate.

Further, in the above embodiment, the handle piece 2 is moved from a position where the first pressing operation portion 23 of the handle piece 2 is substantially perpendicular to the front panel 111 serving as the front end surface of the substrate body 110a. The front panel 1 is rotated to a position that is substantially parallel to the front panel 1. The locked portion 25 of the handle piece 2 is not limited to this type, and the locked portion 1 of the board body 1 10 a The locked part 25 of the handle piece 2 is unlocked from the front panel 1 11 a of the board body 1 1 0 a, and the locked part 25 of the handle piece 2 is Stop portion 1 1 2 Locked to the position where the projecting length of the handle piece 2 from the front panel 1 1 1 of the board body 1 110 a is shorter than the standing state, preferably the board body 1 1 0 The distance from the front panel 1 1 1 as the first end face of a to the second end of the handle piece 2 is The distance from the front panel 1 1 1 as the first end face of 0a to the first end of the handle piece, or the front panel 1 1 1 as the first end face of the board body 110a The range up to the position where the protruding state becomes smaller and smaller than the distance to the first end of 2 can be changed as appropriate by rotating the range.

Also, in the above embodiment, the stackable and usable subrack 120 is used as a circuit storage frame for extracting and unloading the circuit board to which the insertion handle 1 is attached, but the circuit storage frame is However, the present invention is not limited to this embodiment, and may be, for example, a frame used alone, and may be appropriately changed.

In the handle for extracting a circuit board according to the present invention, the second end of the handle piece is connected to a handle of the board main body with the second rotation center as the center of rotation in accordance with the pressing operation of the first pressing operation portion. By rotating toward the stop portion and rotating toward the handle locking portion together with the handle support portion with the first rotation center as the center of rotation, the board body is rotated. The projecting length of the handle piece from the first end face is shorter than that in the upright state. By doing so, it is possible to reduce the protruding length of the handle piece from the end surface of the substrate main body in a state where the substrate main body is inserted into the substrate storage frame. As a result, when installing the board storage frame that houses the circuit board, it is possible to reduce the installation space without disturbing the extraction handle, and to prevent the insertion handle from being hit by other objects. Can be reduced. On the other hand, when removing the circuit board inserted into the board storage frame from the board storage frame, release the lock between the locked part and the handle locking part, rotate the handle piece, and rotate the second rotation center part. If the center is rotated, the distance between the second pressing operation unit and the first rotation center can be gradually increased according to the rotation. With this, when the second pressing operation portion is pressed, the second handle contact portion abutting on the second handle contact portion of the substrate housing frame can be rotated with a small force, and the operation can be facilitated. .

In addition, since the locked portion is provided at the second end together with the pressing operation portion, the handle locking portion of the substrate body and the locked portion are locked, and the locked portion is moved from the handle locking portion. The protrusion of the second end between the handle locking portions of the substrate body can be suppressed. As a result, it is possible to use the board efficiently without reducing the usable range on the center side between the handle locking portions in the substrate body.

Also, for example, when another subrack is stacked on a subrack as a board storage frame that contains a circuit board, when operating the handle piece of the insertion / extraction handle, the insertion / extraction handle stored in the other subrack is used. Since the handle pieces of the sub-rack protrude from the end face of the substrate body in a short state, the handle for insertion and removal stored in another subrack can be made easy to operate without obstruction.

The handle for inserting and removing a circuit board according to the present invention includes the unlocking operation portion. Therefore, when the locked portion locked by the handle locking portion is to be released from the handle locking portion, the unlocking operation portion is required. The operation can be easily performed.

The second pressing operation portion of the handle for inserting and removing a circuit board according to the present invention is a handle locking portion that locks the locked portion when the handle locking portion and the locked portion of the board main body are locked. And the other handle engaging portion provided on the first end surface of the substrate body for engaging the other handle for forming a pair with the handle. To be installed in By doing so, the second pressing operation unit is attached to the substrate body. It can be made so that it does not project between the handle locking parts. This allows efficient use without reducing the usable range on the center side between the handle locking portions of the board body.

In the handle for inserting and removing a circuit board according to the present invention, a finger is inserted between at least the handle locking portion and the first pressing operation portion from a position where the handle locking portion and the locked portion are locked. The range up to the position where it can be obtained is rotated with respect to the handle support with the second rotation center as the center of rotation. The second handle abutment portion of the handle support portion abutting the second handle abutment portion of the frame can be easily rotated around the second rotation center portion as the center of rotation. The distance between the first pressing operation portion and the second pressing operation portion of the handle for inserting and removing a circuit board according to the present invention gradually increases as the distance from the second rotation center increases. By doing so, for example, when the circuit board is pulled out from the board storage frame by gripping the first pressing operation section and the second pressing operation section, the hand is hard to slip from the first pressing operation section and the second pressing operation section. it can. Thus, the circuit board can be easily pulled out of the board storage frame.

Further, the handle support portion of the handle for inserting and removing the circuit board of the present invention has a handle piece storage portion for accommodating at least a part of the handle piece when the handle piece is rotated toward the handle locking portion of the board body. Even when the thickness of the handle piece is increased, at least a part of the handle piece can be stored in the handle piece storage portion when the handle piece is rotated toward the handle locking portion of the board body. The protrusion length of the handle piece from the can be shortened. Therefore, for example, even when the handle piece is formed thick so that the first pressing operation portion and the second pressing operation portion can be easily grasped when the circuit board is pulled out from the board storage frame, the handle Can be reduced in length. Furthermore, the handle for inserting and removing a circuit board according to the present invention, even when a subrack containing a circuit board and another subrack are stacked, as the handle piece of the pulling handle rotates, for example. It can be made so that it does not hit other insertion / extraction handles stored in black. 'This allows the insertion handle to rotate smoothly.

The handle support of the handle for inserting and removing the circuit board of the present invention is Since the urging force of the urging member is received through the handle piece and is urged in the same direction as the handle piece, the handle piece can be urged against the handle support portion by one urging member. At the same time, the handle support can be biased against the substrate body. As a result, the number of parts can be reduced, the assembling process can be simplified, and the device can be manufactured easily and at low cost.

The handle for inserting and removing a circuit board according to the present invention can be bent from the handle supporting portion. Therefore, when the circuit board is inserted into and removed from the board storage frame by the handle piece, the handle protrudes from the board body. Can be operated with a longer length. On the other hand, after the circuit board is inserted into the board storage frame, the length of protrusion from the board main body can be shortened to lock the handle locking portion and the locked portion of the board main body. With this, when installing the board storage frame that houses the circuit board, it is possible to reduce the installation space without disturbing the handle for extraction, and there is a possibility that other objects may hit the handle for insertion and removal. Can be reduced.

Also, for example, when another subrack is stacked on a subrack as a board storage frame that houses a circuit board, when operating the handle piece of the insertion / extraction handle, the insertion / extraction handle stored in the other subrack is used. The handle piece of the sub-rack has a shorter protruding length from the end face of the board body, so the pull-out handle stored in another subrack can be made easy to operate without obstruction.

Although the present invention has been described above as preferred embodiments, each term is used for description, not for limitation, and departs from the scope and spirit of the present invention. Without departing from the scope of the appended claims, it can be modified.
