Description

[Detailed explanation of the idea] This invention relates to lighting equipment.

The cord pendant shown in FIGS. 1 to 3 is made by caulking a tension stopper 2 to a round cord 1, passing the lower end of the cord 1 through the insertion hole 4 of the instrument body 3,
The pair of ears 2a of the tension stopper 2 are passed through the through groove 5 formed in the insertion hole 4, and a holding groove 6 is formed at a position perpendicular to the through groove 5 at the lower edge of the insertion hole 4. This is a structure in which the socket 8 is attached to the main body 3 by hooking it onto the main body 3 to support the main body 3, and connecting the connecting portion 7 of the cord 1 to the terminal of the socket 8. 9 is the lamp connected to the socket, 10 is the appliance body 3
It is a shade hung on the roof.

However, when assembling this lighting device, the lug 2a of the tension stopper 2 may come off from the holding groove 6 and be located in the through groove 5, or the operator may not lock the lug 2a in the holding groove 6. If you forget or if the metal fitting 2 is not sufficiently caulked to the cord 1, the weight of the device may be too large for the lead wire 1a of the cord 1 and the socket 8.
7, causing poor contact, heat generation, non-lighting, arcing, etc., and furthermore, there was a risk that the connection would come off and the appliance would fall.

Therefore, the purpose of this invention is to be able to maintain the connection state reliably without causing poor contact even if the tension stopper is not retained in the retaining groove or is insufficiently attached to the cord, and also to ensure that the tension stopper is not retained in the retaining groove. It is an object of the present invention to provide lighting equipment that can prevent mistakes.

An embodiment of this invention is shown in FIGS. 4 to 7. That is, this lighting fixture has a pair of socket terminal holding protrusions 13 hanging down from the lower hole edge of the cord insertion hole 12 of the fixture body 11, and a metal fitting passage groove continuous with the insertion hole 12 and the protrusion 13. 14 is formed, and a holding groove 15 is formed at the lower hole edge of the insertion hole 12 at a position perpendicular to the groove 14. socket 1
Reference numeral 6 forms a pair of recesses 17 for receiving the projections 13, and a plate-shaped connection terminal 19 is provided between the recesses 17 at a portion of the dividing plate 18 facing the projections. Further, a tension stopper 22 with a pair of ears 21 is caulked to the cord 20, and a flat connecting portion 24 is formed on the lead wire 23 of the cord 20. 25 and 26 are socket mounting holes.

In this lighting fixture, the lower end of the cord 20 is passed through the insertion hole 12 of the fixture body 11, penetrated through the passage groove 14 of the lug 21 of the tension stopper 22, and the lug 21 is rotated 90 degrees (rotation of the main body ) and lock the lug 21 in the holding groove 15. The connecting part 24 of the lead wire 23 at the tip of the cord 20 is folded over and engaged with the tip of the protrusion 13, the protrusion 13 is fitted into the socket 16, and the lead wire 23 is inserted through the mounting hole 26 of the socket 16 with a screw (not shown). Attach to the mounting hole 25 of the main body. At this time, the connection portion 24 is brought into pressure contact with the surface of the plate-shaped connection terminal 19 of the socket 16 due to the support of the protrusion 13 and is thus connected. Further, the weight of the device is borne by the entire cord as the lug 21 is engaged with the holding groove 15.

With this configuration, after the lead wire 20 is connected to the socket 16 and the socket 16 is attached to the instrument main body 11, the ear piece 21 of the tension stopper 22 is connected.
Even if an attempt is made to lock the lead wire 23 into the holding groove 15, the connecting portion 24 of the lead wire 23 becomes loose as shown in FIG. Further, even if the cord 20 of the tension stopper 22 is not properly attached, the projection 13 presses the connecting portion 24 against the terminal 19, so that the contact will not be separated. Furthermore, even if one hooked lug 21 comes off from the holding groove 15 during work, the passage groove 14
Since the lug 21 is formed so that it does not rotate and engage with the passage groove 14 and pass through, the lug 21
has a retaining effect by locking onto the hole edge. Even in such an unsatisfactory condition, terminal connection failures do not occur, and heat generation, non-lighting, and arcing can be prevented.

As described above, the lighting equipment of this invention has a holding protrusion for the lead wire connection part on the main body, and a groove for passing the tension stopper through the holding protrusion, which prevents operator mistakes and prevents terminal connections. is reliable, and even if tension is applied to the terminal part, there will be no contact failure, and there is no possibility that the metal fittings will inadvertently fit into the grooves during work.
