Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a mounting structure for a lamp cap.

[Background technology]

When attaching the lamp cap to the cap mounting section, it is necessary to connect the cap shell of the lamp cap and the cap eyelet with the lead wire of the cap mounting section.

However, in the past, there have been disadvantages in that the work of connecting the base shell and the lead wire is complicated, the workability is poor, and the connection reliability is lacking.

[Purpose of invention]

The purpose of this invention is to provide a lamp cap mounting structure that allows for easy and reliable connection of lead wires.

[Disclosure of invention]

This device has a cap mounting thread formed in the base step, and a lead wire exposure hole formed at the tip of the cap mounting screw and at a continuous position between the base step and the base of the cap mounting screw. A mounting portion, a lead wire passed through the cap mounting portion from the inside and drawn out to each of the lead wire exposure holes, a cap shell and a cap eyelet, and the cap shell is screwed into the cap mounting screw portion. At the edge thereof, the lead wire of the lead wire exposure hole at a position where the base step and the base of the base mounting screw part are continuous is pressed against the base step and soldered to the base shell, and the other wire is attached to the base eyelet. It is equipped with a cap to which a lead wire is connected.

According to this invention, since the lead wire is pressed and fixed to the base step by the edge of the cap shell, the mechanical retention of the lead wire is reliable, and workability is improved because the lead wire is soldered in this fixed state. Moreover, the connection can be made more reliably, and the solder protrusion and lead wire attachment position are stabilized, which improves the ease of attachment to the socket.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 7. That is, the mounting structure of this lamp cap is such that the cap mounting screw portion 1 is formed at the base step portion 2, and the position of the tip of the cap mounting screw portion 1 and the position of the base step portion 2 and the root portion of the base mounting screw portion 1 are adjusted. a base mounting part 5 in which lead wire exposure holes 3 and 4 are formed in consecutive positions; and lead wires 6 and 7 that are passed through the base mounting part 5 from the inside and drawn out to the respective lead wire exposure holes 3 and 4. and a cap shell 8 and a cap eyelet 9, and by screwing the cap shell 8 into the cap mounting screw portion 1, the end edge 1
0, the lead wire 6 is pressed against the base step 2 and soldered to the base shell 8, and the base 11 is connected to the base eyelet 9 with the other lead wire 7.

The base attachment part 5 is formed at the end of the appliance body 12, and a ballast 13 and other lighting components 13' are arranged inside, and the lead wires 6 and 7 are used for receiving power. The cap 11 has a through hole 15 formed in the center of the base body 14, around which a cap shell 8 is fixed, and a cap eyelet 9 is formed at the outer end of the through hole 15. In this case, to attach the cap 11, pass the lead wires 6, 7, which have already been wired to the lighting component 13', through the lead wire exposure holes 3, 4 from inside the cap mounting part 5, and then insert the cap eyelet 9 into the fixture body 12. and the lead wire 7, and screw the cap shell 8 of the cap 11 into the cap mounting screw portion 1 of the cap mounting portion 5 from the state shown in FIG. Then, the lead wire 6 pulled out from the lead wire exposure hole 3 is pressed against the mounting step 2 by the end edge 10 of the cap shell 8 and fixed. FIG. 2 shows this state. With the lead wire 6 fixed, the tip of the lead wire 6 is bent as shown in FIG. 3, and the lead wire 6 is inserted into the base shell 8.
Solder and connect.

With this configuration, the lead wire 6 is mechanically held by the base shell 8, and can be easily and reliably soldered from the outside. Moreover, since solid soldering can be performed, the reliability of electrical connection can be easily improved. In addition, a lead wire exposure hole 6 is formed at a position that is continuous with the mounting step 2 and the base of the cap mounting screw 1, and since the mounting location of the lead wire 6 is restricted, the position of the solder protrusion is stabilized. , the reliability of the electrical and mechanical connection with the other socket is improved.

The instrument body 12 has an upper body 16 as shown in FIG.
and a lower body 17, a hole 19 for the lamp socket lead wire is formed in the joint part 18, and a pair of arm attachment parts 20, 21 are formed in the upper body 16 and the lower body 17, and both are riveted. 2
The upper main body 16 and the lower main body 17 are integrally formed by caulking and connecting the upper main body 16 and the lower main body 17, and the arm mounting portion 20 of the upper main body 16 has a pair of elasticity imparting slit grooves 23 formed at the end thereof. An intermediate piece 23a partitioned by 23 is formed thin for elastic deformation, and a protrusion 24 is formed on the upper surface of the intermediate piece 23a. The lamp support arm 25 has a semi-cylindrical support part 27 at its tip that supports the annular fluorescent lamp 26, and a recess 28 that fits into the arm attachment parts 20 and 21 at its base end. A tapered dowel groove 29 is formed at the edge of the recess 28 in correspondence with this, and an elongated hole 30 is formed inside the groove. The lamp support arm 25 is attached by fitting the recess 28 into the arm attachment parts 20 and 21.
At this time, the dowel groove 29 engages with the protrusion 24 and the dowel groove 2
9, the intermediate piece 23a having a protrusion 24 is elastically deformed by the slit groove 23, and the protrusion 24 is inserted into the elongated hole 3.
It is fixed by engaging with 0. In this way, the projection 24 and the elongated hole 30 are attached to the lamp support arm 25.
Therefore, the lamp support arm 25 can be easily attached to the arm attachment parts 20, 21, and is difficult to come off. In particular, by forming the dowel groove 29 in a tapered shape, it becomes easy to insert and difficult to remove.
Furthermore, the projection 24 eliminates the possibility that the lamp support arm 25 will be attached backwards, improving safety.

As shown in FIG. 7, a socket 31 for connecting the instrument main body 12 is provided at the lower end of a hanging fitting 32, and a hanging threaded portion 33 is provided at the upper end of the hanging fitting 32.
Install it on the ceiling, etc.

[Effect of idea]

According to this invention, since the lead wire is pressed and fixed to the base step by the edge of the cap shell, mechanical retention of the lead wire is reliable, and workability is improved because the lead wire is soldered in the fixed state. Moreover, the connection can be made more reliably, and the protruding amount of solder and the mounting position of the lead wire are stabilized, which has the effect of improving the ease of mounting to the socket.
