Description

[Detailed explanation of the invention] This invention interposes a joint frame with a jetty between the commonly used switch box and the waterproof outlet, and connects the jetty of the joint frame to the rubber seat at the bottom of the waterproof outlet. By fitting and installing it into the circumferential groove of the switch, the joint frame, switch box, and waterproof outlet can be properly combined and engaged, and this design is designed to completely prevent water from seeping into the switch box. This invention relates to a combination of a switch box, a joint frame, and a waterproof outlet.

Prior Art In the conventionally commonly used combination of a switch box and a waterproof outlet, a rubber seat with a circumferential groove attached to the bottom of the waterproof outlet is placed over the top of the switch box. The switch box and waterproof outlet are combined and glued together using screws, but at this time, the rubber seat of the waterproof outlet has a circumferential groove, so it is difficult to combine and glue the switch box and waterproof outlet together. If you tighten the screws too much, the circumferential groove of the rubber seat will be crushed, and if you don't tighten the screws enough, it will be difficult for the circumferential groove of the rubber seat to come into close contact with the top opening of the switch box. A complete waterproof effect could not be expected by simply gluing the switch box and waterproof outlet together via a rubber seat with a circumferential groove.

Therefore, in this invention, in the intervention of a joint frame with a jetty,
We devised a way to achieve a complete combination of a switch box and a waterproof outlet with a rubber seat with a circumferential groove.

Structure of the device This device is related to the creation of a technical idea that reasonably achieves the above purpose. Below, as an example of a means that embodies this device, we will explain the drawings based on this structure. To explain, a joint frame A is made, in which a jetty 2 is provided on the upper surface of a rectangular frame 1 with a fitting side 3, and a small hole 7 and inward projecting pieces 8 and 9 are provided on the side. Attach the frame A and the mating side 3 to the top opening 4 of the switch box B, and attach the rubber seat plate 6 with the circumferential groove 5 attached to the bottom of the waterproof electrical outlet C to the top opening 4 of the switch box B. Place it on the attached joint frame A, fit the circumferential groove 5 of the rubber seat 6 to the jetty 2 of the joint frame A, and attach the switch box B, joint frame A,
A waterproof outlet C and an enclosure of a rubber seat 6 are combined and connected.

The fitting side 3 of the joint frame A is fitted into the top opening 4 of the switch box B and installed, and the metal frame 10 that is tiled on top of the joint frame A is
Through the communication of the screws 11 and 12, the projecting piece 8°9 of the joint frame A is screwed into the seats 13 and 14 together with the small hole 7, and the screw that leads to the waterproof outlet C is screwed into the small hole 15 and 16 of the metal frame 7. Bast and glue switch box B and waterproof outlet C together.

Functions, Effects, and Implementations of the Invention This invention has the following functions and effects since it is related to the above-mentioned configuration.

That is, this invention creates a joint frame A in which a jetty 2 is provided on the upper surface of a rectangular frame 1 with a fitting side 3, and inward projecting pieces 8 and 9 with small holes 7 are provided on the sides. Attach the fitting side 3 to the top opening 4 of the switch box B, and place the rubber seat plate 6 with the circumferential groove 5 attached to the lower bottom of the waterproof outlet C onto the joint frame A of the top opening 4 of the switch box B. Place it on the rubber seat 6
The circumferential groove 5 of the switch box A is fitted into the jetty 2 of the joint frame A, and the switch box B, the joint frame A, and the waterproof electrical outlet C are brought into alignment by connecting and tightening screws.

Therefore, when using this invention, the jetty 2 on the top surface of the joint frame A at the top opening 4 of the switch box B fits into the circumferential groove 5 of the rubber seat 6 at the bottom of the waterproof electrical outlet (C). and the circumferential groove 5 can be well bonded, so that the waterproof outlet C and the switch box B can be properly and correctly matched by communicating and tightening the screws with the interposition of the joint frame A, and thus the waterproof outlet C) This effectively prevents water from entering C and switch box B, resulting in a completely waterproof effect.

That is, when using this invention, the jetty 2 of the joint frame A attached to the switch box B is fitted into the circumferential groove 5 of the rubber seat plate 6 of the waterproof outlet C in a supporting manner. , switch box B and waterproof electrical outlet) C,
Even if tightening is done by connecting screws, the presence of the jetty 2 of the joint frame A prevents the circumferential groove 5 of the rubber seat 6 from being crushed below the height of the jetty 2, so the circumferential groove remains sound. By existing in this form, the switch box B and the waterproof outlet C can be joined together in a controlled and safe manner, and the role of waterproofing can be well fulfilled.

That is, in this invention, waterproofing by joining the switch box B and the waterproof electrical outlet (C) is achieved by fitting the jetty 2 of the joint frame A with the circumferential groove 5 of the rubber seat 6, so the jetty 2 and the circumferential Even if the screws are inadvertently tightened a little too tightly when fitting into the groove 5, the waterproof effect can still be achieved.

Furthermore, since the jetty 2 of the joint frame A attached to the top opening 4 of the switch box B fits into the circumferential groove 5 of the rubber seat 6 at the bottom of the waterproof outlet C, the switch box B top opening 4 and waterproof outlet) C rubber seat 6
The circumferential groove 5 of the switch box B and the waterproof outlet C are normally connected and supported in the fixed position. This serves to ensure the positioning of the combination adhesive.

In short, in this invention, the top opening 4 of the switch box B has a simple opening shape, but the fitting side 3 of the joint frame A is fitted into this opening shape.
The jetty 2 is fitted into the circumferential groove 5 of the rubber base 6 attached to the bottom of the waterproof outlet C, the waterproof outlet C, the rubber base 6, the joint frame A, and the switch box B. By tightening the enclosures in series with screws, the enclosures can be joined together reliably and strongly, and water ingress from any of these joints can be properly and completely prevented. , has the effect of maintaining airtightness well.

This invention uses a joint frame A, which has a jetty 2 on the top surface of a square frame 1 and a fitting side 3 on the bottom surface, interposed between a conventional public switch box and a waterproof outlet, and It is a practical and effective device that is easy to use, allows the switch box and the waterproof outlet to be fixed in place and accurately, and has a perfect waterproof effect.

Although it is possible to use a synthetic resin board as the material for making the joint frame A of this invention, it is not necessarily limited to this material.
