DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the connector for connecting boards between boards according to the present invention will be described in detail below.

FIG. 1 is a conceptual exploded perspective view showing a connector portion 10 which is a main component of the connector for connecting boards between boards according to the present invention.

The connector member 10 is an insulating housing 11 integrally formed of a synthetic resin such as plastic.
And a plurality of contacts 12 facing each other along the longitudinal direction of the housing 11.

On the other hand, on the upper surface of the housing 11, opposed to each other, positioning projections 11a having a substantially U-shape in plan view are provided.
11b, a plurality of mounting holes 14 are formed on both sides of the housing 11, respectively, and a fixing bracket 13 forming a part of the hook means 40 is mounted in the plurality of mounting holes 14.

One of the plurality of mounting holes 14 has a pair of projections 13a forming the fixing bracket 13 fitted in one of the mounting holes 14a, and an L-shaped cross section in the other mounting hole 14b. The other pair of protrusions 13b of the shape is fitted.

When the fixing bracket 13 is fitted and supported in the corresponding mounting holes 14a and 14b as indicated by arrows, a connector member with the fixing bracket 13 is provided as shown in the conceptual perspective view of FIG. 10 are formed.

One of the projections 13b of the fixing member 13 provided on the connector member 10 forms a part of the hook means 40.

On the other hand, as shown in FIG.
On one side, a plurality of contact pads 21 electrically connected to the contacts 12 are formed at positions facing the plurality of contacts 12 provided on the surface of the connector member 10 in FIG. On both sides of the substrate 20, a pair of engagement holes 22 forming the other of the hook means 40 are formed. The length L1 of the other substrate 20 is substantially the same as or slightly smaller than the length L2 between the pair of positioning projections 11a and 11b formed on the upper surface of the housing 11 shown in FIG. Width W1
Is set shorter (W1 <W2) than the width W2 of the pair of positioning projections 11a and 11b formed on the upper surface of the housing 11 shown in FIG.

In this embodiment, a flat cable 23 is connected to each contact pad 21 of the other substrate 20.

On the other hand, as shown in FIG.
0, one of the substrates 30 connected to the
A connector member fitting support hole 31 for fitting and supporting the attached connector member 10 is formed. The size of the connector member fitting support hole 31 is the same as or slightly smaller than the length L2 and the width W2 (FIG. 2) between the pair of positioning projections 11a and 11b formed on the connector member 10. A pair of holes 32 are formed on both sides of the connector member fitting support hole 31 so as to insert one of the protrusions 13a of the fixture 13 mounted on the connector member 10, respectively.

Such a connector member fitting support hole 31 is provided.
In order to mount the connector member 10 on one of the substrates 30 on which is formed a pair of positioning projections 11a, 11b of the connector member 10 in the connector member fitting support holes 31 as shown by arrows in FIG. And at the same time, the fixing bracket 13
Is inserted into a pair of holes 32 at opposing positions (FIG. 5).

Thereafter, the one protrusion 13a is fixed in the pair of holes 32 by fixing means 33 such as soldering as shown in FIG. Needless to say, in order to solder the projection 13a into the hole 32, a wiring pattern is formed in and around the hole 32.

As shown in FIG. 6, when one of the protrusions 13a is fixed in the pair of holes 32, the connector member 10 is fitted in the connector member fitting support hole 31 and is fixed to the one substrate 30. Will be supported. In this case, each rear end 12a of each contact 12 shown in FIG. 1 is fixed by soldering or the like to a corresponding wiring pattern (not shown) formed on the back surface of one substrate 30 shown in FIG. .

Next, in order to electrically connect one substrate 30 on which the connector member 10 shown in FIG. 6 is mounted and the other substrate 20 on which the contact pads 21 shown in FIG. 3 are formed, as shown in FIG. Then, the contact pad side formed on the other substrate 20 is made to face the connector member 10 disposed on the one substrate 30, and then the connector member 10 as shown by an arrow.
Is brought into pressure contact with the contact portion 12b of the contact 12 disposed in the above. At this time, as shown in FIG. 8, each of the engagement holes 22 forming a part of the hook means 40 formed on the other substrate 20 is fixed to the other of the hook means 40 protrudingly provided at a position facing the engagement hole 22. The projection 13b of the metal fitting 13 is fitted and inserted.

At this time, the entire other substrate 20 is slidably disposed between the pair of positioning projections 11a and 11b of the connector member 10.

When the board 20 is slid in the direction of the arrow from the arrangement state of the other board 20 shown in FIG.
As shown in FIG. 9, the engagement holes 22 of the other substrate 20 constituting the hook means 40 are respectively fitted into the projections 13 b having the L-shaped cross section constituting the hook means 40, and the other substrate 20 is Positionally supported by the connector member 10 via the hook means 40, and at the same time, the contact portion 12b of the contact 12 and the contact pad come into contact with each other, so that the one substrate 30 and the other substrate 20 are electrically connected. .

In order to release the electrical connection between one substrate 30 and the other substrate 20, the other substrate 20 is moved from the position of the substrate 20 shown in FIG.
Since the engagement between the engagement hole 22 forming the hook means 40 and the projection 13b having an L-shaped cross section is released, the other substrate 20
Can be easily removed from one substrate 30.

Therefore, according to the connection state between one substrate 30 and the other substrate 20 shown in FIG.
Are connected via the connector member 10 in a state of being buried inside one substrate 30, so that the one and the other substrates 2 are connected.
The total thickness of the combination of 0 and 30 is extremely thin as compared with the conventional one.

The other substrate 2 with respect to the one substrate 30
0 is also connected via the hook means 40 to the other substrate 20.
Is simply slid, so the connection workability is also greatly improved.

[0030]

As described above, according to the connector for board-to-board connection of the present invention, the connector member provided with the contacts is mounted in the connector member fitting support hole formed on one of the boards. Further, since the other substrate on which the contact pads are formed in the contact member is slid via the hook means so as to be electrically connected to the one substrate, the overall thickness of the connector for connection between the substrates is extremely thin. Not only that, the connection and disconnection of one and the other substrates can be performed by a simple operation of sliding the other substrate, thereby significantly improving the connection between the substrates and the maintenance and inspection workability thereof.
