Description

[Detailed Description of the Invention] (Industrial Application Field) A printed circuit board inserted into the case of an electronic device is tightly connected to a connector, so it is difficult to remove it from the case.

The present invention relates to a printed circuit board extraction device in which a handle is attached to a printed circuit board, and the printed circuit board can be easily extracted by grasping the handle.

(Prior art) Conventional extraction device (for example, Utility Model Application No. 53-148163
Since the handle is pinned to the printed circuit board, not only is a tool required to drive the pin in to attach the handle, but the shock caused by driving the pin can loosen the electronic components on the printed circuit board, resulting in poor contact. There was a risk that this could occur.

(Problems to be solved by the invention) The present invention makes the entire handle integrally made of synthetic resin, eliminates the need for an assembly process, and allows the handle to be easily and securely attached to the printed circuit board. The purpose is to prevent damage to the circuits on the board without applying shock.

(Means for solving the problem) The present invention includes a handle that is integrally formed of synthetic resin, and has protrusions on both sides and an intermediate plate between the protrusions, and a protrusion on the inner surface of the intermediate plate. Insert a printed circuit board between both protrusions and the intermediate board, fit the protrusion into a through hole bored on the side opposite to the plug part of the board, and insert the protrusions provided at both ends of the back side of the protrusions into the ends of the board. This is a printed circuit board extraction device that connects a handle to the board by pressing against the edge.

(Function) In the extraction device of the present invention, both protrusions and the middle plate sandwich the substrate in the direction perpendicular to the surface of the substrate, and the protrusion and the convex surface in the direction parallel to the surface of the substrate. Support in immobility.

(Example) To explain the present invention based on an example shown in the drawings, 1 is a printed circuit board whose upper and lower sides are
The board 1 is slidably inserted into the parallel guide grooves 2, 2 provided in the case of an electronic device such as a computer, and the board 1 is inserted into the case, thereby inserting the plug portion 3 at the tip into the connector 4 inside the case. It is electrically connected to a large number of printed contacts 5 provided in the plug section 3.

Next, the synthetic resin handle 6 has protrusions 7 on both sides.
7 and an intermediate plate 8 is formed between them, and a protrusion 9 is provided on the inner surface of the intermediate plate 8. The upper surface of the projection 9 is sloped low toward the tip of the middle plate 8.

The board 1 has upper and lower parts 2 on the opposite side from the plug part 3.
Through-holes 10, 10 are respectively bored in the two locations, and the board 1 is inserted between the protrusions 7, 7 of the two handles 6 and the middle plate 8, and the protrusions 9 are inserted into the through-holes 10, 10.
The handle 6 is thereby connected to the substrate 1.

When inserting the board 1 between the protrusions 7, 7 and the middle plate 8 of the handle 6, first insert the board 1 obliquely along the slope of the upper surface of the protrusion 9, and then insert the board 1 obliquely between the protrusions 7, 7 and the middle plate 8. By gradually inserting the board 1 deeply parallel to the protrusions 7, 7 and the middle plate 8 while expanding the gap between the protrusions 7, 7 and the middle plate 8, the substrate 1 can be easily inserted between the protrusions 7, 7 and the middle plate 8. Can be inserted.

Convex surfaces 11 are provided on both ends of the back sides of the protrusions 7, 7, and the protrusions 9 are firmly fixed to the through holes 10 by pressing the edges of the substrate.

Therefore, in order to remove the printed circuit board 1 from the case, the printed circuit board 1 can be reliably removed from the case by grasping the handles 12 formed on each handle 6 and pulling out the circuit board 1.

Note that in a small-sized printed circuit board, the connector is also short and the bonding strength between the two is relatively weak, so it is sufficient to connect one handle 6 to either the upper or lower side.

(Effect of the invention) As described above, according to the invention, the projection 9 of the handle 6 is fitted into the through hole 10 of the printed circuit board 1, and in addition, the protrusion 9 of the handle 6 is fitted into the through hole 10 of the printed circuit board 1.
1 allows the handle 6 to be easily and securely connected to the board 1 by pressing the edge of the board. At this time, there is no impact, so the board will not be damaged. 9 is also integrally formed from synthetic resin and does not use any parts, so there is no need for an assembly process and 1 is made of synthetic resin molding.
It has the advantage of being able to be manufactured in a process and mass-produced at low cost.
