The exemplary panel connector 41 is assembled such that the female connector member 43 slides up and down inside the connector base 44 .

That is, the vertical surface 50 of the connector base 44 and the guide plate 45
Two cylindrical or round rod-shaped shafts 74 of the female connecting member 43 are inserted into the gap formed between the female connecting member 43 and the box-shaped guide structure 46, so that the thin connecting member 43 is connected to the connecting tool base 44. It is assembled so that it can be slid up and down inside.

FIG. 8 shows a panel connector 4 according to a second embodiment of the present invention.
1 is attached to a panel board 77. Mounting notches 79 are provided at opposing positions at the same height on the panel board 77, and panel connectors 4 are installed in the mounting notches 79.
1 is inserted and fixed to form a connected panel 78.

In this case as well, in order to maintain the connection strength and to prevent the connected connected panels 78 from twisting at the connection points, the connected panels 78 are connected at two or more locations. A plurality of panel connectors 41 are attached to both sides at the same height positions.

The connection operation will be explained with reference to FIG.

When the connected panels 78 are not connected, the panel connectors 4
1, as shown in FIG. 5(a), the female connecting member 43 is lowered below the connector base 44 to cover the female connecting member 42.

When connecting the connected panels 78, if their heights are aligned, the panel connectors 41 will face each other at the same position.

By sliding the female connecting member 43 of the panel connecting tool 1 on one side upward, the conical connecting arms 64 and 65 appear as shown in FIG. 5(b). Pinch the conical connecting arm 64 as shown in FIG. 5(c).
Bow 65 towards you.

Next, attach the pulled out conical connecting arms 64 and 65 to the shaft 5.
1, rotate 90 degrees or 180 degrees, and insert the conical connecting arm 64.65 into the circular hole 71 of the female connecting member 43 of the panel connector 41 to be connected. Insert the head 61 of the attached connecting pin 63,
The neck 62 of the connecting pin 63 is inserted into the narrow groove 7 of the female connecting member 43.
The coupling operation is simply completed by moving the conical coupling arms 64, 65 downwards so as to slide them along 1.

As shown in FIG. 5(d), the female connecting member 43 of the panel connector 41 using the female connecting portion 42 is slid downward to an intermediate position. The connecting operation is completed by covering a part of the area, but the last operation is not necessarily necessary as a connecting operation.

As shown in FIG. 9(a), when connecting the connecting panels 78 in a horizontal-letter shape, the male connecting arms 64 and 65 are
Rotate once to connect both sides of the connected panel 78.

The male connecting arms 64,65 of the panel connectors 41 are connected to the female connecting members 43 of the panel connectors 41 of the third and fourth interlocking panels 78, respectively, by rotating them by 90 degrees.

Therefore, when connecting panels in an L-shape, only the panel connector 41 on one side is used to connect the panels.
Although the connection strength is not strong, there is no problem in practical use.

The connection can be easily disconnected by performing the reverse procedure of the connection operation.

By using the panel connector 41 according to the present invention, there is no gap between the connected connected panels 78. Further, the panels can be connected arbitrarily by the user regardless of whether the panels are on the front or back.

Due to the structure of the panel connector 41, there is no protrusion from the panel surface when not in use, and the connected panel 78
Even when used singly, problems due to protrusion of foreign matter do not occur.

Both sides 68.69 of the female connecting member 43 have ends 72.73.
Since they are connected by the shaft 74, both sides 68 and 69 will not open even if the connected panels 78 are stretched in a connected state. Further, since the female connecting member 43 which is not in the connected state presses down the male connecting arm 64.65 in the connected state by its own weight, it is possible to prevent the male connecting arm 64, 65 from becoming disconnected.

In order to enable the connection angle at an angle other than 90 degrees or 180 degrees, the panel plates 31 and 770 angles are formed into four semicircular shapes, and as shown in FIG.
This can be achieved by forming the corners 24 and 44 into four semicircular shapes, respectively.

That is, in the first embodiment, as shown in FIG. 11(a), the mounting portions 5 and 6 of the female panel connector 1 are formed to have a width that is approximately the same as the length between the two shafts 9. Also,
The corners of the U-shaped upper surface 7 and lower surface 8 on the mounting portion 5 and mounting portion 6 sides may be formed in a quarter circle shape connected to the edges 11, 14, and 15, with the shaft 9 attached as the center. good.
