Description

[Detailed description of the invention] [Industrial application field] This invention relates to electrical wiring in an elevator car.

This particularly concerns the wiring connected to the car operation panel.

[Conventional technology]

Conventionally, many electric wires are led to the car operation panel, so
Various ideas have been made for the wiring.

For example, as described in Japanese Utility Model Application Publication No. 54-11470, there is a device in which terminal blocks are mounted in a stepped manner.

Figure 5 shows a technical idea similar to that disclosed in the above publication, in which (l) is a hoistway, (2) is a car room,
(2a) is the car door, (3) the platform and operation panel, (4) is the tail cord, (4a) is the hanger that fixes the tail cord (4) to the car compartment (2), (4b) is the tail cord (
4) Connect the car operation panel (3) with the connector connected to the second terminal.
It is pulled in all at once from the bottom.

[Problem that the invention seeks to solve]

Conventional electrical wiring in an elevator car, especially the wiring to the car operation panel, is pulled in all at once from the bottom opening and the connectors are installed centrally as shown above, so the wires run through and it is difficult to check the wiring during elevator installation. It was difficult to perform adjustment work, and maintenance and inspection work was also time-consuming. In addition, the case itself was sometimes made deeper to alleviate this noise.

As a result, the wing walls become thicker, reducing the effective area of the car, resulting in a problem of reducing the loading capacity. Yet again. Attempts were made to make the case extremely long and spread out the wire connections, but this also resulted in an unsightly appearance.

This invention solves the above-mentioned problems, and aims to provide electrical wiring for an elevator cab that is easy to install and maintain by avoiding congestion of electric wires.

[Failure to solve the problem]

The electrical wiring of the elevator car according to the present invention is as follows.

A vertical wire through hole is formed on one side of the case of the car operation panel, a duct with an opening on the side opposite to the wire through hole is attached to the outer wall of the car room, and the electric wire is stored in this duct. The electric wires were then set up and distributed vertically, and the electric wires were drawn into the case.

[Function] The electric wires to the car operation panel are widely distributed in the vertical direction and drawn in to avoid congestion of the electric wires.

[Embodiments of the invention]

1 to 4 show an embodiment of the present invention.

In the figure, the same reference numerals as in Figure 5 indicate the same parts, and (5) is a sleeve that rotates 90 degrees via the hinge (5a) and whose side edge is normally fixed in contact with the doorway post (2b). The wall (6) is a duct installed along the outer wall of the car compartment (2) on the side opposite to the entrance/exit pillar (2b) of the control panel (3), and the tail cord (4a) is held in place by a hanger (4a). 4) is stored.

The car operation panel (3) is shown in Figure 4.
- the face plate (3a) and the face plate (3a);
), the case (sb), the back cover (3C) that covers the side opposite to the face plate (3a), and the face plate (5).
Wire through holes (5d) are drilled at the necessary locations on the - side of the case (3b) set up along line a), and the tail cord (
4) The connector (3e) is connected to a wire that is inserted through the case (3b) and leads to an instrument installed in the case (3b).

In other words, the car operation panel (3) is vertical and the case (3) is vertical.
b) Distribute and cut the tail cords (4) in accordance with the instruments inside, and attach the connectors (4b). This tail cord (4) is drawn into the case (3b) through an appropriate wire through hole (3d) and connected to a connector (5e).

Also, the rising part of the tail cord (4) is connected to the duct (6).
Therefore, there is no problem even if the car room (2) is raised or lowered or the car door (2a) is opened or closed.

Yet again. During installation and maintenance, it is necessary to rotate the wing wall (5) and open the back cover (5C) as shown in Figure 3. Along with this, the tail cord (4) is pulled, but since the wire through hole (3d) is vertical, it moves as shown by the symbol (4') in FIG. Connector (36') 9 (4b) and case (3b)
) No large force is applied to the appliance terminals.

In the above embodiment, the wing wall (5) was assumed to be rotatable, but it was fixed to the entrance/exit post (2b).

The present invention can also be applied to a car operation panel in which the case (3b) is embedded in the fixed wing wall (5).

〔Effect of the invention〕

In addition to the above-mentioned aspects, the present invention includes forming a vertical electric wire through hole on one side of the case of the car operation panel, and installing a duct having an opening on the side opposite to the electric wire through hole on the outer wall of the car room. The wires are stored in this duct, raised, distributed vertically, and drawn into the case, which prevents the wires from crowding inside the case and makes installation and maintenance easier. have an effect.

[Brief explanation of drawings]

Claims (1)

[Claims] In a device that is connected to a car operation panel installed by burying the case in the wing wall of the car room, a plurality of electric wire through holes arranged vertically or in line are formed in one side of the case, and the electric wires pass through the car. A duct having an opening on the side opposite to the hole is attached to the outer wall of the car compartment along the case, and the electric wires are stored in this duct, raised and distributed in a vertical direction, and the electric wires are passed through the through hole into the case. Electrical wiring for an elevator car, characterized in that the above-mentioned electric wires are drawn in.
