Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grommet device for preventing damage to a cable routed through a through hole provided in a wall surface.

[0002]

2. Description of the Related Art Generally, an automatic processor is provided with a processing solution tank for storing a processing solution such as a developing solution, a fixing solution, and washing water.
The photographic light-sensitive material is processed by successively immersing it in this processing solution. The photosensitive material is driven by rollers provided in the processing rack in each processing solution tank, guided and conveyed along a predetermined path (substantially U-shaped path), and passes through the processing solution.

Each processing liquid tank is provided with pipes for supplying a replenishing liquid, a diluting water, etc. These are controlled by driving a pump, opening and closing a valve, and the like.

The photosensitive material which has been processed in the processing liquid tank is
It is sent to the drying section and dried. Possible methods include a type in which hot air heated by a heater is directly blown onto the photographic light-sensitive material, a type in which the photographic light-sensitive material is brought into contact with a roller heated by a heater, and a type in which far infrared rays are irradiated. There is also a drying section that uses these in combination.

In the automatic processor, many electric parts such as a driving source of rollers of the processing rack, a heater of a drying section, a power source of far-infrared lamps, a driving source of pumps and valves, etc. are arranged. It is controlled according to the signal. The external casing of the automatic processor is provided with a monitor display section for notifying the operator of the processing status and an operation section for receiving an instruction from the operator with a push button or the like.

Usually, the control unit is installed in a place as far as possible from the place where the treatment liquid is present, and the electric parts here are covered with a cover member which prevents the treatment liquid from adhering to the control unit, or at the beginning. Since, it is waterproofed or has chemical resistance.

Here, from the control unit, it is necessary to provide electrical wiring to the electric parts scattered and arranged at various places in the automatic developing machine. For this reason, this electric wiring (cable) has to be wired at various places in the automatic developing machine, and, for example, is integrally molded with the processing liquid tank and penetrates the leg portion (wall surface) supporting the processing liquid tank. It may also be wired.

As described above, in order to connect the control unit, the heater, and the drive source, which are separated from each other, by electric wiring, a grommet (rubber bush) formed by an elastic member is usually fitted into a through hole formed in the partition wall. , To prevent damage due to contact between the cable and the inner peripheral surface of the through hole.

[0009]

However, the provision of the through holes in the partition wall causes a possibility that the processing liquid may come in contact with the through holes. For example, as described above, when the wall surface supporting the processing liquid tank is integrally formed with the processing tank and the through hole is formed, the processing liquid leaking from the processing liquid tank may adhere to the cable along the wall surface. . Since the cable used has chemical resistance, there is no problem with the cable itself, such as electrical leakage. However, when the cable is transmitted (when the cable is in the form of a harness, capillary phenomenon Can occur), leading to control units and electrical parts that are not chemically resistant.

Also, the cable itself may cause fatigue on the surface of the cable due to chemical change of the chemicals deposited over time.

In consideration of the above facts, the present invention prevents damage due to contact with a wall surface when a cable, particularly an electric cable, is arranged so as to penetrate the wall surface, and adheres liquid flowing along the wall surface. The purpose is to obtain a grommet device capable of preventing the above.

[0012]

According to a first aspect of the present invention, there is provided a cable which is fitted around a through hole provided in a wall surface where dripping can occur and which is wired through the through hole. A grommet part that prevents damage to the cable due to contact with the inner peripheral surface of the through hole, and a side where liquid drip may occur on the wall surface when the grommet part is fitted, and continues from the lower part of the grommet part A flare composed of a receiving portion formed of a substantially horizontal portion and an upwardly continuing portion thereof, a substantially horizontal portion continuous from the upper portion of the grommet portion so as to cover the receiving portion from above, and a downwardly continuing portion thereof. And a grommet portion and a dripping prevention cover portion integrally formed with a flexible material.

According to the first aspect of the invention, the grommet portion is fitted around the through-hole provided on the wall surface, whereby the device is fixed to the wall surface. In this state, when the cable is passed through the hole of the grommet portion, the hole of the grommet portion cannot be visually observed because the drip prevention cover portion has the liquid drip prevention cover portion extending in a tubular shape from the grommet portion.

The dripping prevention cover section is divided into a receiving section and a flare section. In a normal state, these sections form a closed cross section (cylindrical shape), but since these are flexible, the receiving section and flare section are formed. By elastically deforming one or both of the parts, they can be easily separated. In this state, the hole of the grommet portion can be visually confirmed, and the work of passing the cable can be facilitated.

When the dripping prevention cover part is returned to its original position (it naturally returns due to the restoring force after elastic deformation), the flare part covers the periphery of the receiving part, so that the liquid dripping on the receiving wall along the wall surface It can be guided to the outside of the side wall, and the liquid does not adhere to the cable. Therefore, the liquid does not transfer to the control device, the electric parts, etc. through the cable to cause electric leakage or corrosion, and the life of the device can be extended. Also, the cable itself will not fatigue over time.

According to a second aspect of the present invention, in the invention according to the first aspect, a portion of the dripping prevention cover portion facing upward of the receiving portion is a lower surface of the substantially horizontal portion of the flare portion or a portion facing downward. It is characterized by being in contact with the inner surface of the.

According to the second aspect of the present invention, since the receiving portion has a structure that covers the inside and the flare portion covers the outside thereof, liquid does not flow in between them, and a waterproof effect is obtained. There is.

A third aspect of the invention is characterized in that, in the first aspect of the invention, the flexible material is resistant to a processing solution for a photographic light-sensitive material.

According to the invention described in claim 3, since the grommet device itself has resistance to the processing liquid,
There is no problem if the liquid directly adheres to the grommet device.

According to a fourth aspect of the present invention, in the first aspect of the invention, a downward opening is provided between the receiving portion and the flare portion of the dripping prevention cover portion. I am trying.

According to the fourth aspect of the invention, since the opening for wiring is directed downward, the liquid does not enter the opening, and the path of the liquid traveling through the cable can be cut off. .

As shown in FIGS. 2 and 3, the through hole 8
A rubber grommet 84 is fitted in each of 0 and 82, and the surface of the cable 78 and the through holes 80 and 82 are inserted.
It prevents damage caused by contact with the inner surface of the. The grommet 84 is formed as a part of the protective body 86. A liquid drip prevention cover 88 is integrally formed with the grommet 84.

The dripping prevention cover 88 is provided on the concave portion 74 side in the present embodiment.

As shown in FIG. 4, the dripping prevention cover 8
8 is a receiving portion 90 extending from the end surface of the grommet 84 corresponding to the lower half of the through holes 80 and 82, the through hole 80,
The flare portion 92 extends from the end surface of the grommet 84 corresponding to the upper half of 82, covers the receiving portion 90, and guides the liquid dripping on the receiving portion 90 to the outside of the side wall.

The receiving portion 90 and the flare portion 92 have portions that overlap each other, and usually form a closed cross section. Therefore, the cylindrical space extended from the through holes 80 and 82 is formed.

As a result, the processing liquid that has fallen down from the wall surface portion 70A is received by the flare portion 92, and the flare portion 9 is received.
Since it will be dripped from the end of No. 2, the structure is such that no liquid enters into the cylindrical space.

Further, in this embodiment, the dripping prevention cover 86 is bent at a substantially right angle immediately after extending from the grommet 84, and the cylindrical space faces the opening direction of the recessed portion 74 along the wall surface. There is.

Here, while the receiving portion 90 is extended to the position where the tip reaches the inclined portion 76A of the rib 76, the flare portion 92 has a portion corresponding to the inclined portion 76A of the tip portion. It is inclined downward, and the tip is at the same position as the height of the bottom of the receiving portion 90. Therefore, the tip end opening of the dripping prevention cover 88 faces downward, and the cable 78 is wired from this downward opening through the cylindrical space to the opening (through holes 80, 82) of the grommet 84.

Although the two protective bodies 86 are arranged so as to be vertically overlapped with each other, the downward openings are not shielded by the inclined portions 76A of the ribs 76 and the inclined portions of the flare portions 92, respectively. The cable 78 has a structure that allows it to freely pass therethrough.

It may leak and fall along the wall surface portion 70A.

In such a case, the cable 78 receives the receiving portion 9
Since it is covered with 0 and the flare portion 92, the processing liquid that has propagated through the wall surface is not directly applied to the cable 78, and the processing liquid is prevented from being guided through the cable 78 to the electric parts and the control unit. It For this reason, deterioration due to chemicals contained in the processing liquid of the electric components and the control unit, corrosion due to moisture, etc. are prevented, and the life can be extended. In addition, it is possible to prevent the cable 78 itself from being deteriorated by a chemical.

In the present embodiment, the protector 86 is attached to the through holes 80 and 82 provided in the wall surface portion 70A continuous with the processing tank of the automatic developing machine 10, but the object to be attached is not limited to the automatic developing machine.
