Japanese Patent Publication No. 63-66130

  An elevator may require a waterproof / drip-proof structure for an indicator or the like depending on the situation of the installation site. In order to achieve a waterproof / drip-proof structure in the prior art, it is necessary to bond the fixing device 4 using a rubber bushing and also bond the locking plate 15 and the wiring box 12 with a complicated structure. In addition, there is a problem that a complete waterproof / drip-proof effect cannot be expected.

  The present invention provides an electrical wiring device having a configuration in which an insertion port through which an external wire connector can be inserted is opened on one side of the wiring box, and the external wire connector is inserted into the insertion port and the external wire is mounted. An attachment member having a configuration that is wider than the opening and through which the external electric wire can be inserted; and a flexible member that has an area wider than the insertion opening and through which the external electric wire can be inserted; The connector side of the external electric wire is inserted through the mounting member and the flexible member and enters the wiring box from the insertion port, and the mounting member is on one side of the wiring box across the flexible member It is the electric wiring apparatus of the elevator characterized by being fixed to.

In the present invention, the external electric wire is fixed to the attachment member, and the attachment member has a notch through which the external electric wire can pass.
The flexible member is fixed to the mounting member, the external electric wire is a cable, and the size of the hole formed in the flexible member is equal to or smaller than the outer dimension of the cable. Furthermore, rubber is used as the flexible member.

  According to the present invention, a waterproof / drip-proof effect can be achieved with a relatively simple configuration.

An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an overall explanatory view, FIG. 2 is a partial cross-sectional front view showing a mounting state of an external electric cable, and is a view corresponding to FIG. 9, FIG. 3 is a left side view of FIG. It is.
In the figure, reference numeral 30 denotes a wiring box such as an indicator or a landing pushbutton component, and an insertion port 32 through which the external wire connector 20 is inserted is opened at the center of the back surface portion 31, and insert nuts (for example, stocks) are provided above and below the box. A “lobatin” (registered trademark, etc.) 33 of the company Lobtex is attached. Reference numeral 40 denotes an external electric cable, which is the same as the branch line 6 in FIG. 7, and an external electric wire connector 20 is attached to the tip of the external electric cable. Here, two external electric wire connectors 20 are provided, but one or three or more may be used.

  When attaching the external electric wire cable 40 to the wiring box 30, the external electric wire connector 20 and the tip of the external electric wire cable 40 are routed through a U-shaped cutout 43 provided on one piece 42 of the angle-like attachment member 41. It passes through a hole 45 formed in a plate-like flexible member 44 made of rubber. Since the dimension of the hole 45 is equal to or smaller than the outer dimension of the external electric cable 40, the flexible member 44 and the external electric cable 40 are in close contact. Then, the external electric cable 40 is fixed to the other piece 47 of the attachment member 41 by the bundle band 46. The work so far can be made in advance in a factory or the like as in the prior art, or can be done on site.

Next, as shown in FIG. 2, the distal ends of the external wire connector 20 and the external wire cable 40 are inserted into the wiring box 30 from the insertion port 32, and the bolt 50 is placed in one piece 42 with the mounting member 41 and the flexible member 44 interposed therebetween. The external electric wire cable 40 is attached to the wiring box 30 by being screwed into the insert nut 33 from the hole 48.
Thereafter, the external electric wire connector 20 is connected to the internal electric wire connector as in the prior art, and the operation is completed by attaching an indicator or a landing call button component to the front portion of the wiring box 30.

As described above, the present embodiment is configured by combining the attachment member 41 and the like mainly for fixing the external electric cable 40 and the flexible member 44 mainly responsible for the waterproof / drip-proof function. An elevator electrical wiring apparatus having a waterproof and drip-proof effect can be realized with a relatively simple configuration.
Moreover, since the external electric wire cable 40 is inserted into the notch 43 of the mounting member 41, even if the external electric wire connector 20 is large, it can be inserted without any problem. Further, since the hole 45 is opened in the flexible member 44, the external wire connector 20 can easily pass through the hole 45.

In the above-described embodiment, the external electric cable 40 is fixed to the mounting member 41 by the bundling band 46. However, the present invention is not limited to this, and other types such as a clamp and a bind line that sandwich the external electric cable 40 may be used. . Nut welding may be used in place of the insert nut 33. Furthermore, although the example which provided the insertion port 32 in the back surface part 31 of the box 30 for wiring was shown, even when the insertion port is provided in addition to a back surface part, it is the same.
Further, although the attachment member 41 and the flexible member 44 are separated, the flexible member 44 can be fixed to the attachment member 41 in advance. Furthermore, although the attachment member 41 has an angle shape, it is not limited to this.

It is the whole explanatory view showing an embodiment of the invention. It is a partial cross section front view which shows the attachment state of an external electric wire cable. FIG. 3 is a left side view of FIG. 2. It is a left view of an attachment member. It is a perspective view of the conventional wiring box. It is a perspective view of the conventional latching plate. It is a side view of the conventional latching components. It is a perspective view of the conventional indicator pushbutton component. It is a partially longitudinal side view which shows the assembly state of the conventional electric wiring apparatus.
