Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a crosspiece for attaching a terminal block and a wiring duct in a power distribution box.

[Conventional technology]

Conventionally, the terminal block and the wiring duct were separately installed in the wiring duct in close proximity to each other via dedicated crosspieces, which increased the number of parts and was disadvantageous in terms of space.

Therefore, it was proposed in Japanese Patent Application Laid-Open No. 54 (1972) to support the base plate in a floating state on the board surface inside the wiring box via a support member that also serves as a spacer, and to mount both the terminal block and the wiring duct on this base plate. −57195
It is known in the publication no. It is also disclosed therein that the mounting surface of the terminal block is bent diagonally downward and extended with respect to the mounting surface of the wiring duct on the base plate.

[The problem that the idea attempts to solve]

However, the conventional base plate is fixed to the panel surface of the switchboard via the separate support member, and there are still many parts, and the support member is fixed to the panel surface, and then the base plate is attached to the support member. It requires fixing and has poor assembly workability.

Furthermore, a light terminal block is placed on the fixed end side of the base plate fixed to the support member, and a heavy wiring duct is placed on the free end side of the base plate, so that the tip side of the base plate bends downward. There is a risk of deformation. Of course, this problem can be solved by supporting the base plate in a state where it is supported on both sides, but this will only further increase the number of parts and worsen the assembling workability.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a crosspiece that requires a minimum number of members, has excellent assembly workability, and allows a terminal block and a wiring duct to be attached together.

Another object of the present invention is to provide a mounting crosspiece that can firmly support a terminal block and a wiring duct without causing deformation in the installed state.

[Means to solve the problem]

The present invention relates to a crosspiece installed inside a wiring box to which a terminal block 1 and a wiring duct 2 can be attached together, and includes a horizontally elongated upper plate part 3 on the left and right sides, and a crosspiece extending downward from the rear end of the upper plate part 3. It is made of a long shape material having a mounting plate part 4 bent at right angles and extending out, and a terminal block mounting plate part 5 bent diagonally downward from the front end of the top plate part 3. It can be installed on the power distribution box side, and the terminal block mounting plate part 5
A long hole 6 for installing the terminal block 1 is formed in at least one of the top plate part 3 or the mounting plate part 4.
It is characterized by the formation of

[Effect of idea]

The crosspiece of the present invention can be directly attached to the power distribution box side via the mounting plate part 4, and the wiring duct 2 can be attached to the mounting plate part 4 or the top plate part 3 to mount the terminal block that cantilevers forward. The terminal block 1 can be attached to the plate part 5 at the same time. Therefore, the number of parts can be kept to a minimum, and the assembly workability is also excellent.

Heavy wiring duct with built-in wiring cord 2
is attached to the mounting plate part 4 or the top plate part 3. In other words, the light terminal block 1 is mounted on the upper surface of the terminal block mounting plate part 5 extended cantilevered forward. Therefore, the crosspiece of the present invention does not suffer from bending deformation when installed and in use.

Then, attach the mounting plate 4 to the top plate 3.
is bent downward at an almost right angle, and the terminal block mounting plate 5 is bent downward diagonally, so
Needless to say, in the state shown in FIG. 2 where the wiring duct 2 is attached to the mounting plate 4, even in the state shown in FIG. Since the work space is effectively formed even though the wires are close to each other, wiring work can be carried out well.

In addition, since the terminal block 1 and the wiring duct 2 can be directly attached to the mounting surface of the crosspiece A through the long holes 6 and 7, respectively, the positions can be easily adjusted during installation, and the number of parts can be reduced in this respect as well. Can be reduced to the minimum necessary.

[First Embodiment] Figures 1 to 3 show the first embodiment of the present invention, and A is the mounting crosspiece of the present invention for installing the terminal block 1 and the wiring duct 2 inside the power distribution box. .

This mounting crosspiece A is an elongated member that is long from side to side, and includes a horizontal upper surface plate portion 3, and a mounting plate portion 4 that is bent downward at a right angle from the rear end thereof.
It consists of a terminal block mounting plate part 5 which is bent diagonally forward and downward from the front end of the top plate part 3. Horizontally elongated holes 6 and 7 are formed in the terminal block mounting plate part 5 and the mounting plate part 4 at predetermined pitches in the left and right longitudinal directions, respectively.

The terminal block 1 is equipped with a transparent plate 10 that covers the terminals 9.

The wiring duct 2 has a U-shaped cross section and a cover 12 can be detachably attached to the duct body 11.
Elongated notch holes 13 are formed in the both side walls of 1 in the longitudinal direction.

The proposed crosspiece A is directly attached, for example, between left and right perforated supports 15, 15 via the mounting plate 4 in the power distribution box. In this direct mounting, the elongated hole 7 of the mounting plate part 4 and the vertical elongated hole 16 of the support column 15 are used to fix it with the screw 17a.

Next, attach the bottom wall of the wiring duct 2 to the mounting plate part 4.
and attach it with screws 17 through the elongated hole 7. Further, the terminal block 1 is attached to the upper surface of the terminal block mounting plate part 5 with screws 18. The terminal block 1 is now supported in an inclined position relative to the horizontal top plate 3, and the wiring cord drawn out from the wiring duct 2 can be easily connected to the terminal 9 on the terminal block 1.

[Second Embodiment] Fig. 4 shows a second embodiment of the present invention. In this case, the front and rear width of the top plate portion 3 is increased, and a long hole 7 is inserted in the front and rear center of the top plate portion 3 in the left and right longitudinal direction. The wiring duct 2 was mounted on the top plate part 3 at a fixed pitch through the long holes 7 with screws 17, and the rest of the structure was the same as that of the first embodiment. Also in this example, since the terminal block 1 is installed in an inclined position, an effective wiring work space can still be secured between it and the wiring duct 2.
