JPS5924142Y2 - ceiling rosette - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a ceiling rosette.

Conventionally, there are sealing rosettes that use screw terminals to connect switch circuits and feed circuits, but because they use screw terminals, it takes a lot of time to connect and install them.

Moreover, since the terminals for power supply and transmission wiring are not arranged in a straight line, there is a drawback that the size becomes large.

The present invention was developed in view of the above-mentioned drawbacks, and its purpose is to enable easy connection and disconnection of power lines and feed wiring, as ceiling lighting equipment becomes more diverse. , to provide a sealing rosette that can be connected to an electrical appliance with a U plug.

The present invention will be explained below with reference to examples. Figures 1 to 5 show an embodiment of the present invention, and the main body 1 includes a body 2 to which a charging part is attached, and a lower part fitted into the body 2, as shown in Figures 2 and 3. It is composed of a cover 3 that is attached together to protect the live part.

A pair of fitting holes 4, 4 are provided on the upper surface of the inner bottom of the body 2 to fit the hook blades provided in the hook cap (not shown), and the hook blades and the slider are inserted into the fitting holes 4, 4. The contact fittings 5a and 5b for the hook blades which are in contact with each other are shown respectively.

Further, as shown in FIG. 1, a pair of first terminal plates 6a and 6b are connected along a center line perpendicular to the center of a line connecting the pair of fitting holes 4-14, and each of the first terminal plates 6a and 6 A power supply connecting terminal block A for connecting a power line consisting of a pair of first locking springs 7a, 7b and a first release button 8 corresponding to b, and a pair of second terminal plates 9a, 9 b, and a pair of second terminal plates 9 a and 9 b corresponding to each second terminal plate 9 a and 9 b.
A feed wiring connection terminal block B consisting of locking springs 10a, 10b and a second release button 11 is arranged at a predetermined position in a substantially straight line.

In the figure, reference numeral 12 denotes an insulating plate disposed inside the body 2 above one of the hooking blade contact fittings 5a;
2 is provided with a partition wall 13 that partitions both sides of the insulating plate 12, and on the insulating plate 12 on both sides of the partition wall 13, U
Blade holder fittings 14a and 14b for inserting and connecting connection plug blades of a plug (not shown) are provided, respectively, and holes are formed on the side of the body 2 to correspond to the blade holder fittings 14a and 14b. Together with the blade insertion port 15.15, the outlet portion C is configured.

Reference numeral 16 denotes a mounting hole in the main body 1 for mounting to a construction material.

Reference numeral 17 denotes a partition wall protruding from the inner bottom surface of the body 2.

In addition, the cover 3 is provided with the first terminal of each connecting terminal block A, B.
．． The first terminal for introducing electric wires to be connected to the second terminal plates 6a, 6a, 9a, 9b. Second wire hole 18,1
8.19.19 and 1st. Window holes 20a, 20 for operating the second release buttons 9, 11 with a jig such as a screwdriver
b.

However, in the ceiling rosette of the present invention, the power wire is inserted into the first wire hole 18.18 and connected.
The power line is connected to the first locking spring against the spring force of the first locking springs 7a and 7b.
By press-fitting between the locking springs 7a, 7b and the first terminal plates 6a, 6b, the power wires are connected to the first locking springs 7a, 7.
It is connected to the first terminal plates 6 a and 6 b by the elastic force of b.

One first terminal plate 6a is connected to one hook blade connecting fitting 5b.
and one blade holder 14 a and one second terminal plate 9
a, and the other first terminal plate 6b is connected to the other hooking blade connection fitting 5a, the other blade holder fitting 15b, and the other second terminal plate 9b, and the second terminal plate 6b is connected to the other one by the connected power wire. Power is supplied to the quick-connect terminal block B of No. 2, the outlet portion C, and the connection fittings 5a and 5b for the hook blade.

When connecting the transmission line, insert the second locking springs 10a, 10b and the second locking springs 10a, 10b into the second wire hole 19.
A power transmission line is held under pressure between the terminal plates 9a and 9b,
Transmission lines can be connected to power lines.

When removing the connected electric wire, use the first and second window holes 20a.
, 20b, push a rod-shaped jig such as a screwdriver into the first
By moving the second release buttons 8 and 11 in the direction of the arrow X in FIG. 5, the first and second locking springs 7 a and 7 b are released.
What is necessary is to compress 10a, 10b and pull out the electric wire.

The ceiling rosette of the present invention formed in this way is attached to a ceiling construction material such as a pole edge, and each hook blade of a hook cap (not shown) connected to a light fixture is inserted through the fitting holes 4, 4, respectively. Insert each hooking plug blade connection fitting 5a
, 5 b so that the lamp can be suspended by slidingly engaging with it.

In this invention, as mentioned above, the terminal for connecting the power line and the terminal for the feed wiring are each constructed from independent connecting terminal blocks, so that it is easy to connect and disconnect the electric wires, and the connection of the other side is easy. It has the advantage of safely connecting and disconnecting the power supply because the terminal blocks do not affect the connection, and each quick-connect terminal block is arranged in a straight line in a direction perpendicular to the center of the line connecting the pair of fitting holes. In addition, the outlet section is placed above one of the contact fittings for the hook blade, so each terminal block can be placed in the center, allowing for the shortest distance to the contact fitting and blade holder. The quick-connect terminal block for power supply can be connected with the quick-connect terminal block for power supply, and even when connecting the quick-connect terminal block for power supply and the quick-connect terminal block for feed wiring, it can be done in the shortest distance, so the arrangement of internal parts can be made compact. The overall size can be made smaller, and since the outlet section is provided, it is possible to connect a power supply device with a U plug, making it easy to use.Also, since there is an insulating plate at the bottom of the outlet section, there is no need to cut the blade. This has the advantage of not only being able to insulate the receiving fitting and the contact fitting for the hooking blade, but also preventing the chips of the blade receiving fitting from falling toward the contact fitting, and eliminating the electrical influence caused by the accumulation of cutting chips.
