Description

[Detailed explanation of the invention] [Purpose of the invention] (Industrial application field) This invention is applied to the T-shaped wiring part of a line gutter that protects power and communication wires that are wired on the floor or wall. This invention relates to metal line gutter connectors used.

(Prior Art) Line gutters have conventionally been molded from synthetic resin, but because harmful gases are generated in the event of a fire, there is a demand for line gutters molded from metal. The connection tool used for the T-shaped wiring part of the metal gutter is the first
As shown in FIGS. 0 to 12, coupling devices 3 bent downward in a U-shape are fitted in the middle of the three gutter portions 2 of the approximately T-shaped main body 1, and the lower ends of both sides of the coupling devices 3 are fitted. The coupling tool 3 is engaged with each gutter portion 2 by engaging the engaging portion 5 formed on both sides of the lower end of each gutter portion 2, and then the main body 1
A substantially T-shaped cover 7 having gutter cover portions 6 having a U-shaped cross section on three sides is fitted onto the upper surface of the coupling tool 3.
The cover 7 is fixed to each connector 3 by inserting a screw 8 into the gutter cover part 6 fitted above and screwing this screw 8 into the female screw hole 9 of the connector 3, and then attaching the cover 7 to the main body 1. A fixed structure was used.

(Problem to be Solved by the Invention) When using a line gutter connector having the conventional structure as described above, when the cover 7 is engaged with the main body 1, three connectors 3 are connected to the gutter portions 2 at three locations. Since both sides of the gutter cover 6 are engaged with each other and the three gutter cover parts 6 fitted thereon are screwed, a large number of parts are required and the construction is time-consuming.

In view of the above-mentioned problems, the purpose of the present invention is to provide a metal line gutter connector that can connect a cover to the gutter body with one screw, is easy to install, and has a small number of parts. It is something.

[Structure of the idea]

(Means for Solving the Problems) The metal line gutter connector of the present invention includes a line gutter body formed from a metal plate, a cover formed from a metal plate covering the top surface of the line gutter body, and a gutter body formed from a metal plate. and a connector molded from a metal plate that connects the gutter main body and the cover. The line gutter main body includes a straight portion having a substantially U-shaped cross section with the peripheral wall portion bent upward on both side edges, and a straight portion extending in a right angle direction from the center portion of one side of the straight portion via an inclined edge. It has a base plate part consisting of a branch part having a substantially U-shaped cross section with peripheral wall parts formed on both side edges, and an inclined connecting part between the peripheral wall part on one side of the straight part of the base plate part and the peripheral wall part of the branch part. and a central portion of the peripheral wall portion of the other side edge of the straight portion, respectively, and a fitting portion is formed by cutting out the fitting portion, and an engaging portion that bulges upward and opens outward is formed at the bottom of the fitting portion position. ing. The connector includes a generally triangular upper plate portion with a screw hole formed approximately in the center thereof, and is bent downward from each corner of the upper plate portion and is fitted into each fitting portion of the line gutter body. It has leg pieces that fit together, and engaging pieces that are bent from the lower end of each leg piece and are respectively engaged with the engaging portions of the gutter main body. Further, the cover includes a substantially T-shaped cover plate portion that covers the upper surface opening of the line gutter body and has a screw insertion hole formed in the substantially central portion corresponding to the screw hole of the connector; and a peripheral wall part that is bent downward from the peripheral edge of the line gutter body and circumscribed by the peripheral wall part of the gutter main body.

(Function) The metal line gutter connector of the present invention is such that the T-shaped wiring part of the electric wire is located inside the T-shaped line gutter body fixed to the floor or wall, and then the triangular shaped wiring part is placed on the center of this body. Position the coupling tool, fit the three downwardly bent leg pieces into the fitting parts of the peripheral wall of the main body, and engage the engaging pieces at the lower ends of the leg pieces with the lower surface of the engaging parts of the main body. This causes the coupling to engage the body.

Next, when a substantially T-shaped cover is fitted from the upper surface, the peripheral wall portions are circumscribed by the peripheral wall portions of the main body, respectively. Next, by tightening the top cover plate of the stacked covers and the top plate of the connector with screws, the cover is engaged with the main body via the connector, forming a connector with connection ports open on three sides. be done.
