Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a drip-proof cover that is attached to a power distribution device of an internal combustion engine such as an automobile engine to protect cable connection terminals from water intrusion, salt damage, etc.

[Prior Art] In general, a drip-proof cover is divided into two parts: a cap-type cover that fits over the power distribution unit and envelops the entire body, and a cap-type cover that is split into two parts and hinged so that they can be opened and closed. It is known that when the cap is attached to a cap, the two cover parts are opened and the cover is fitted to enclose it, and the former cap type is often made entirely of an elastic material such as rubber and has been in practical use for a long time. The latter split-type cover was devised to eliminate the inconvenience of attaching and detaching the cap type, and was proposed in, for example, Japanese Utility Model Publication No. 59-30500. This split type cover is generally made of synthetic resin with both cover parts molded, and one side edge is connected to the other by a hinge means so that it can be opened and closed, and when it is attached to or removed from the power distribution device, it is fitted in the open state and used. Occasionally, a closing means provided on the other side edge, such as a locking pawl, is used to close them together.

In this way, there are two types: single type, and divided type that can be opened freely.
The present invention relates to improvements in these drip-proof covers that are molded from synthetic resin.

[Problems to be solved by the invention] The synthetic resin drip-proof cover minimizes the gap between the cover and the power distributor to avoid occupying the narrow engine room space, and also prevents water droplets from entering through the gap. However, since it is a molded product and a mass-produced product, it is extremely difficult to obtain a cover that can be attached closely to the power distribution device in all cases. For this reason, there is usually some air gap between the power distributor and the cover, which often becomes a source of noise due to vibrations from the engine.

In addition, in the case of conventional synthetic resin covers, the insertion hole through which the cable cord is pulled out is made larger than the actual diameter of the cable in consideration of ease of insertion, but due to the void created here, the cable is subject to engine vibrations. There were problems such as the cable making noise when it hit the cover and damaging the cable sheath due to friction.

The present invention was devised in order to eliminate the noise or friction caused by the gap formed between the drip-proof cover of such a mass-produced molded product and the power distributor or cable.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a cover molded from synthetic resin, more specifically, a cover part that is divided into two parts constituting a cap-shaped cover body. Each inner wall surface is provided with a seismic isolation member made of an elastic material, and when the cover body is attached to the power distribution device, the cover body is brought into close contact with the seismic isolation member via the seismic isolation member. This seismic isolation member is molded separately from the cover main body, and is fixed and assembled to the inner wall surface of each cover part via a locking means that is formed at the time of molding the cover part. The purpose is to provide a drip-proof cover.

On the other hand, the present invention provides a cable clamping means having a U-shaped cross section in the opening provided in each cover part in order to insert the cable, and clamps the middle of the length of the cable pulled out through the opening to the clamping means. This is to prevent the cable passing through the opening from vibrating.
At the same time, in the present invention, the holding means is molded separately from the cover part, and a stop means for attaching the holding means to the opening is provided in advance in conjunction with the molding of the cover part. It is an object of the present invention to provide a drip-proof cover for a power distribution device, in which the above-mentioned clamping means is assembled through.

[Function] Due to the above structure, when the drip-proof cover of the present invention is attached to the power distribution device, the earthquake-proofing member comes into close contact with the outer wall surface of the power distribution device, so even if there is a gap between the two,
This gap becomes the vibration width and the cover body does not vibrate, thus suppressing the generation of noise.Furthermore, the cable pulled out from the power distribution device through the opening is prevented from vibrating by the clamping member. Therefore, collision between the cable and the cover body is avoided.

In addition, by attaching the seismic insulation material, the cover and the power distribution device are brought into close contact, and since the seismic insulation material is made of an elastic material, it is stretchable and can absorb molding errors in the cover body. , a stable wearing condition can be obtained at all times.

In addition, in the drip-proof cover of the present invention, the two cover parts constituting the cover body, the earthquake-proofing member, and the clamping means are each molded separately, and the cover part is provided with a means for attaching these members at appropriate locations. This makes it easy to assemble.

Hereinafter, the features of the present invention will be described in more detail with reference to embodiments.

[Example] Fig. 1 is a perspective view of a drip-proof cover according to the present invention in an open state, Fig. 2 is a front view of the same in an open state, Fig. 3 is a plan view, and Fig. 4 is a partial view. FIG. 5 is a bottom view in section, a front view of the closed state when installed, and FIG. 6 is a cross-sectional plan view.

Cover body 1 substantially shaped like a cap
is approximately the center, and is divided into two to create two cover parts 1
a and 1b, and the abutting edges of both cover parts are hinged by fitting a shaft 2 on one side and a bearing 3 on the other side, and are connected to each other so that they can be opened and closed freely. Openings 5a and 5b each having a U-shaped cross section and forming an insertion hole for pulling out the cable 4 are formed at the upper edge of the free end side of the cover portions 1a and 1b.
are provided facing each other, and furthermore, an elastic locking piece 6a serving as means for restraining both cover portions in a closed state and a locking portion 6b for engaging the elastic locking pieces 6a are provided facing each other approximately at the center of the height.

It goes without saying that the cover body 1 is formed in a shape and size that matches the outer diameter of the power distributor 7 to be attached in the closed state, but the cover body 1 formed here is slightly smaller than the outer diameter of the power distributor 7. It is made large so that a gap can be provided between the two. Two seismic isolation members 8 are provided on the inner wall surfaces of both cover portions 1a and 1b at positions corresponding to the body of the power distributor so as to fill this gap.

The seismic isolation member 8 is used to fill the above-mentioned gap and bring the cover part into close contact with the power distributor to prevent the cover from coming into contact with the power distribution device due to vibrations, and also to absorb the difference in the size of the gap, which is made in advance, and is made of an elastic material. For example, it is molded from a material such as rubber.

In this embodiment, as shown in FIG. 7, two rod-shaped protrusions 9 are planted at intervals on the inner wall surface of each cover member, and a trapezoidal rubber seismic isolation member 8 is pierced through the protrusions. It has been stopped.

The above-mentioned protrusions 9 are arranged in pairs in each cover portion 1a,
1b, two sets each are arranged in four locations on the cylindrical inner wall surface when closed together in a cap shape, and an imaginary circle a connects the tops of the seismic isolation members 8 each engaged with these protrusions. As shown in FIG. 6, the outer diameter of the body of the power distributor 7 coincides with the outer diameter of the body of the power distributor 7 and abuts against it.

On the other hand, the openings 5a and 5b, which have a U-shaped cross section, are provided with stop means 10 facing each other on opposing surfaces, and the cable clamping member 1
1 is installed. The locking means 10 is a locking plate 1 raised from the wall surface via a platform portion 12.
3, and a slit 14 is provided in the center of the locking plate along the longitudinal direction from the opening side. On the other hand, the holding member 11 has two holding parts 15 formed in a U-shape.
are arranged in series, and engaging pieces 16, 16 are provided on both sides of this clamping part.
are provided in parallel, and the locking plate 1 is provided with this locking piece facing the locking means 10 as shown in FIG.
It is designed so that it can be inserted between 3 and locked.

This clamping member 11 can be sufficiently fixed by inserting the engaging piece 16 under the floating locking plate 13. However, a groove 17 is formed on one side of the engaging piece, so that when the engaging piece is inserted, a bulge appears on the wall of the opening. By engaging the provided protrusion 18 with this groove 17, the fastening can be ensured. Note that this clamping member 11
When the two cover members are closed, the end of the clamping member abuts against the engaging piece of the clamping member that is fixed in the other opening (see FIG. 5), so it will not come off when it is attached to the power distributor.

Incidentally, in the illustrated embodiment, two clamping parts 15 are provided in series on one clamping member, but it goes without saying that the number can be selected as required. Although it goes without saying that the diameter of the clamping part 15 is determined by the diameter of the cable to be inserted, a stable clamping state can be obtained by providing elasticity to the clamping part 15 so that it can elastically clamp the cable to be clamped.

The drip-proof cover of the present invention is constructed as explained in the above embodiment, and the cover part 1 is manufactured.
Shaft 2 and bearing 3 are molded separately for a and 1b.
By fitting them together, they are hinged and connected together so that they can be opened and closed freely. Then, the power distributor 7 is faced from the side in an open state, and is wrapped between both cover portions, and the elastic locking piece 6a serving as the closing means is inserted into the gate-shaped locking portion 6b, and the protrusion is inserted into the gate-shaped locking portion 6b. The cable 4 pulled out through the insertion hole is fitted into each holding part 15 to complete the mounting operation.

[Effects of the invention] In the drip-proof cover of the present invention, which is installed and used as described above, the earthquake-proofing member 8 provided on the inner wall of the power distribution device 7 comes into close contact with the power distribution device 7, so that the power distribution device itself is connected to the engine. Even if it vibrates due to vibrations such as earthquakes, it will not collide with the cover and generate noise, and since the above-mentioned seismic insulation member is made of an elastic material, it will adhere tightly to the power distribution device, and its elasticity will allow it to connect the power distribution device and the cover body. Even if there is some variation in the gap, the difference can be absorbed and a constant adhesion state can be ensured, so a certain amount of manufacturing error can be expected, which is advantageous in terms of mass production.

By the way, in the example, it was decided that the seismic insulation member installed on the inner wall surface of the cover part and the clamping member installed in the opening were molded separately from the cover part and assembled. This makes it easy to mold the cover body, making it possible to provide a highly accurate product, and by selecting these parts, it is possible to ensure versatility in responding to changes in the shape of the power distribution device. .
