[0018]
As shown in FIG. 5 (B), the connector main body 4a is U-shaped with an open top, and the longitudinal direction has an appropriate length as shown in FIG. 2, and both ends of the bottom portion hang downward. Are formed on the positioning protrusion 4a '.
[0019]
As shown in FIG. 3, the connector main body 4a is provided with slits 15 in the longitudinal direction and at both ends on the bottom so as to have a width that can penetrate the upper portion of the fixing piece 4b. Further, as shown in FIG. 2, when the operation lever 4c is translated in the X direction from the position of the two-dot chain line and then rotated to the solid line position, the pin 16 provided on the operation lever 4c is provided on the connector body 4a. Positioning grooves 17 whose one side surface is an inclined surface 17a are provided for smooth reception.
[0020]
As shown in detail in FIG. 7, the fixing piece 4b is formed by bending two sides of a square shape into a right angle and overlapping L pieces back to back. Is formed on the base portion 4b "in a standing state, and the thickness of the overlapping base portion 4b" is dimensioned so that it can move in the slit 15, and the upper portion of the base portion 4b "is appropriately adjusted so that it can be accommodated in the connector main body 4a. The length shaft 18 is inserted in a state protruding in the thickness direction.
[0021]
The distal end portion 4c 'of the operation lever 4c is formed in a yoke shape so as to sandwich the base portion 4b "of the fixing piece 4b from both sides, and the base portion 4b" of the fixing piece 4b is inserted inside the distal end portion. By passing the shaft 18 from one side of the 4c 'to the other side, the operation lever 4c is attached to the fixing piece 4b so as to be rotatable about the shaft 18.
[0022]
Further, as shown in FIG. 7B, a cam portion 19 having a top portion at a position orthogonal to the operation portion 4c ″ is formed at the base end portion 4c ′ of the operation lever 4c. The pin 16 is fixed in parallel to the shaft 18 so as to protrude on both sides of the operation portion 4c ″. As shown in FIG. 2, both ends of the pin 16 are rotated when the operation lever 4c is turned to the lying down state. The width of the connector main body 4a is equal to or slightly longer than the width of the connector main body 4a so as not to be disengaged from the positioning groove 17 of the connector main body 4a.
[0023]
Next, as shown in FIGS. 1, 4 and 5, the upper portion of the panel frame 1, 1 'has an upper end plate 1b formed in a recessed shape at a position lower than the upper surface. 4 can be attached.
[0024]
That is, the positioning hole 20 for the positioning protrusion 4a 'of the connector main body 4a is located at a predetermined position in the longitudinal direction of the upper end plate 1b, and the pressure contact portion of the fixing piece 4b is located closer to the end than the positioning hole 20. 4b 'passes through the base 4b "so that only the base 4b" can be moved to the center, and each of the odd-shaped mounting holes 21 is formed by combining a rectangular hole 21a and an elongated hole 21b. Is provided.
[0025]
In the embodiment shown in FIG. 5, the upper end plate 1b is separate from the panel frames 1 and 1 ', but may be formed integrally with the panel frames 1 and 1'. .
[0026]
Next, a procedure for attaching the connector 4 to the upper end plate 1b will be described.
[0027]
The fixing piece 4b of the operation lever 4c is previously attached to the attachment holes 15 and 15 of the connector main body 4a.
[0028]
Next, in order to attach the connector 4 to the upper end plate 1b, the connector 4 shown in FIG. 5 (B) is fitted as shown in FIG.
[0029]
That is, the positioning protrusions 4a 'and 4a' at both ends of one connector body 4a are engaged with the positioning holes 20 and 20 provided in the two serially connected upper end plates 1b and 1b ', respectively, so that the upper end plate 1b is engaged. , 1b ′ temporarily fix the connector main body 4a.
[0030]
After that, the press contact portion 4b 'protruding from the bottom of the connector main body 4a is passed through the mounting holes 21 and 21 provided in the upper end plates 1b and 1b in accordance with the rectangular holes 21a, and then the base portion 4b "is elongated. It moves to the shape hole 21b side.
[0031]
As a result, the pressure contact portion 4b 'of the fixing piece 4b is positioned below the lower surfaces of the upper end plates 1b and 1b', and cannot be pulled upward. This is because the operation lever 4c indicated by a two-dot chain line in FIG. 2 is in a state of being translated in the central direction while standing.
[0032]
From this state, when the pin 16 of the operating lever 4c is slid to a position corresponding to the positioning groove 17 of the connector main body 4a, and the operating lever 4c is rotated at that position as shown by the solid line in FIG. 16 slides on the inclined surface 17a of the connector main body 4a, falls into the positioning groove 17, and the operation lever 4c is locked in this position. The fact that the pin 16 is engaged with the positioning groove 17 means that the base portion 4b ″ of the fixing piece 4b is positioned on the side of the elongated hole 21b of the mounting hole 21, and secure fastening is assured. .
[0033]
On the other hand, the operation of the operation lever 4c causes the cam portion 19 to come into pressure contact with the upper surface of the bottom of the connector main body 4a, so that the lower pressure contact portion 4b 'is pulled up, the upper side is the cam portion 19, and the lower side is the pressure contact portion 4b'. The upper end plates 1b and 1b 'are sandwiched. As a result, the operating lever 4c does not return due to the friction of the cam portion 19 and can be fixed securely.
[0034]
When the fixing is performed securely, the headboard 9 is attached on the panel frame 1 as shown in FIG.
[0035]
FIGS. 8 and 9 show a plan view and a side view of another embodiment of the present invention. In FIGS. 2 to 7, the straight connector 4 is used for the upper end plates 1b and 1b '. The point using the connector 5 is different.
[0036]
Accordingly, since the upper end plates 1b and 1b ″ are arranged so as to form a right angle with each other, the shape of the connector main body 5a of the connector 5 is naturally a shape obtained by bending the connector main body 4a at a right angle at the center. However, the fixing member 4b other than the connector main body 5a constituting the connector 5 and the operation lever 4c can be shared by the connector 4, and the shapes of the upper end plates 1b and 1b ″ are also 1b and 1b ′. Since they are completely the same in structure, the same reference numerals are given to the drawings, and the description thereof is omitted.
[0037]
In the case of the terminal connector 6 that connects the panel frame 1 'and the joint support 2 shown in FIG. 1 at the upper part, a shape obtained by cutting the connector body 4a at the center position is used. Therefore, in this case, the fixing piece 4b and the operation lever 4c are only one of the coupling tool 4, but the mounting method is the same.
[0038]
【The invention's effect】
In the present invention, as described above, the upper end plate is provided as a recessed portion at a position lower than the upper surface of the panel frame with respect to the panel frame, and the panel frames connected to each other by being attached so as not to remove the connector. There will be no problems that cause a gap. More specifically,
1) According to the first aspect, the coupling tool body of the coupling tool is placed so as to straddle between the positioning holes drilled at a predetermined position of the upper end plate of the adjacent low partition. Engage the positioning protrusion provided to the positioning hole to restrain both partitions, and operate the pressing part of the fixing piece placed on the upper surface of the connector body facing the lower surface of the upper end plate. Since the lever is pressed down against the lower surface, the fixing can be smoothly connected and the front and rear of the low partitions do not shift.
[0039]
2) According to the second aspect, in the case of the connection by the fixing of the previous item 1, the operation lever has a pin projecting in advance on the side surface in the vicinity of the pivot point. Since the positioning groove for receiving this pin is provided on the main body side, the pin is positioned by this groove when the operation lever is tilted, and at the same time, the cam portion protruding from the outer periphery of the base end portion of the operation lever is provided on the upper end plate. Since it operates so as to be brought into pressure contact with the lower surface, the connection by fixing is further strengthened, and further, there is no deviation in the front-rear direction between the raw partitions.
