[Industrial application field]

The present invention relates to a printed board unit insertion/removal jig that is formed so that the printed board unit can be inserted into and removed from a motherboard mounted in a housing.

2. Description of the Related Art Electronic devices used in computers and the like are generally formed by mounting a printed circuit board unit in a housing.

Such a printed board unit is usually configured to be removable so as to facilitate assembly work in the manufacturing process and maintenance and inspection during operation.

On the other hand, such printed board units have recently tended to become larger, and as they become larger, they become particularly heavy, making it difficult to mount them in a housing.

Therefore, it is desired to develop a jig that can easily mount such a printed board unit in a housing.

[Conventional technology]

Conventionally, the configuration was as shown in the conventional explanatory diagram of FIG. 4. In FIG. 4, a is a side view, b is a perspective view of the main part, and c is a front view of the main part.

As shown in FIG. 4a, the printed board unit 3 is held by the clamper 13 of the holder 12 provided on the lifter 11 that is moved along the floor 14, and the lifter 11 is moved in the direction of arrow C. , connect the connector 2B and the contact 3B by inserting the guide pin 3A provided on the printed board unit 3 into the guide hole 2A of the thermal board 2,
A printed board unit 3 has been attached to a thermal board 2 mounted on a housing 1.

Further, as shown in b, the printed board unit 3 is provided with a hook 3C having a hook hole 3D on the back side opposite to the side from which the guide pin 3A and the contact 3B are protruded. The printed board unit 3 is held by inserting a pin 13E provided on a movable plate 13D of the clamper 13 shown in FIG.

This clamper 13 consists of a movable plate 13D that is slidably locked by a bar 13A stretched over the holder part 12, and a shaft 13B that is rotated via a gear 13F by rotating a handle 13C. By rotating the handle 13C in the direction of arrow B, the movable plates 13D are formed to expand or narrow as shown in arrow A.

Therefore, by rotating the handle 13C, the pin 13E of the movable plate 13D is moved to the printed board unit 3.
The printed board unit 3 is held in the holder part 12 by inserting it into the hook hole 3D of the lifter 11.
The printed board unit 3 is mounted by moving it in the direction of arrow C and connecting the contacts 3B of the printed board unit 3 to the connector 2B of the motherboard 2.

After installation, the handle 13C is rotated in the opposite direction to that described above, and the pin 13E of the movable plate 13D is removed from the hook hole 3D of the printed board unit 3.
The installation work was completed by moving the lifter 11 in the direction opposite to arrow C.

[Problem that the invention attempts to solve]

In such a configuration, when positioning the printed board unit 3 at the mounting position of the motherboard 2,
It is affected by the accuracy of the plane of the floor 14.

Therefore, even if the guide pins 13E of the printed board unit 3 are aligned with the guide holes 2A of the motherboard 2, if the accuracy of the floor surface is poor, the movement of the arrow C will cause the position to shift, making installation difficult. It had a difficult problem.

Therefore, the present invention aims to reduce the number of assembly steps by facilitating positioning during insertion and removal operations.

[Means for solving problems]

FIG. 1 is an explanatory diagram of the principle of the present invention.

As shown in FIG. 1, a clamper is driven by rotation of a first handle to hold a printed board unit, and a floating table is moved by rotation of a second handle to project or retract the printed board unit. A holder portion is provided, and the holder portion is configured to be locked to a support arm fixed to the housing by a rotation pin.

With this configuration, the above-mentioned problems are solved.

[Effect]

That is, the holder section is provided which is locked to a support arm fixed to the housing, and when the first handle is rotated, the printed board unit is held on the floating table by the clamper of the holder section, and the printed board unit is held on the floating table by the rotation of the first handle.
By rotating the handle, the floating table is made to protrude, and this protrusion allows the printed board unit to be attached to the motherboard mounted in the housing.

Therefore, by moving it like a conventional lifter that moves along the floor, it is possible to prevent misalignment of the positioning, and the insertion and removal work can be easily performed, reducing the number of work steps. can.

〔Example〕

The present invention will be explained in detail below with reference to FIGS. 2 and 3. FIG. 2 is an explanatory diagram of an embodiment of the present invention, in which a is a rear view, b is a side view, and FIG. 3 is an explanatory diagram of the main part of the present invention, in which a is a plan view and b is a sectional view. The same reference numerals indicate the same objects throughout the figures.

As shown in a and b of FIG. 2, the shaft 10D and the guide 1 rotated by the second handle 9
The holder part 10 is formed by providing the floating table 4 slidably locked to the frame 10A by the fixing part 1 of the housing 1.
It is configured to be locked to a support arm 6 fixed to A by a rotation pin 7 and rotated.

Further, the floating table 4 is provided with a clamper 5, which has the same configuration as the clamper 13 described above, and is formed so that the printed board unit 3 can be held by rotating the first handle 8. There is.

Therefore, by rotating the second handle 9, the floating table 4 is projected in the direction of arrow D, and the printed board unit 3 held by the clamper 5 is
is attached to the motherboard 2.

Furthermore, when holding the printed board unit 3, the frame 10A is rotated around the rotation pin 7, as shown in FIG. After holding the printed board unit 3, the opening is closed as shown by arrow E, so that the printed board unit 3 can be easily held. However, it is necessary to provide a locking mechanism that locks the frame 10A from rotating when it is closed.

Also, a floating table 4 is provided with a clamper 5 held by the printed board unit 3.
Tables 4A and 4B are shown in Figure 3b.
A bearing 4 is constituted by two sets of tables, and a bearing 4 is held between them by a protrusion 4D and a metal fitting 4E.
C and is formed to be slidable.

Therefore, when mounting the printed circuit board unit 3 on the motherboard 2, fine adjustment can be made to match the guide pin 3A with the guide hole 2A, and the guide pin 3A is guided to the guide hole 2A, so that the connector 2B
It becomes easy to insert the contact 3B into the contact 3B.

With this configuration, the positioning of the printed board unit 3 does not shift due to the precision of the floor as in the past, and the workability of mounting the printed board unit 3 on the clamper is improved, reducing assembly man-hours. can be achieved.

[Effect of idea]

As explained above, according to the present invention, the holder section is first opened, the printed board unit is held by the clamper by rotation of the first handle, the holder section is closed after holding, and the holder section is then closed. By rotating the handle, the printed board unit can be attached to a predetermined motherboard.

Therefore, there is no positional shift during installation as in the conventional case, and the number of assembly steps can be reduced due to the ease of work, which has a great practical effect.
