Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a structure around a terminal of a ballast for a discharge lamp.

[Background of the invention]

Conventional discharge lamp ballast terminals and lead wires are generally connected in many cases by soldering, but recently there have been some methods that have partially adopted a connection method that does not use soldering, for example, -34749 etc. started to be seen.

However, even if the connecting method is adopted, the need for soldering remains, and discharge lamps that can be selectively used with either soldering or connecting method and have a structure around the terminals that can insulate and protect the conductive parts. A ballast for use is desired.

[Purpose of the invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a ballast for a discharge lamp having a structure in which a lead wire can be connected to the same terminal part by either a connecting method or a soldering method, and the conductive part can be insulated and protected. do.

[Summary of the invention]

In other words, the present invention makes it possible to connect terminals and lead wires and insulate and protect conductive parts by arbitrarily selecting and using connecting blocks and insulating blocks with the same external shape in the same terminal part. , a discharge lamp comprising a terminal block that extends from the end face of a coil bobbin, a terminal that runs along this terminal block and connects the winding end of the coil, and a terminal part that has an engaging surface that is parallel to the axial direction of this terminal. This provides a ballast for use.

[Embodiments of the invention]

One embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Through-coil bobbin 1 attached to an iron core (not shown)
A horizontally projecting terminal block 2 is provided at the terminal block 2, and fitting portions 22 and 23 for fitting and fixing the connecting block 4 and the insulating block 5 inserted from the horizontal direction are provided.

When connecting the terminal 21 provided on the terminal block 2 and the lead wire 6 by a connecting method, the connecting block 4 is inserted from the horizontal direction as shown in FIG. 22 and 23 are fitted and fixed, and then the lead wire 6 from which the insulation coating at the tip has been peeled off is inserted into the lead wire insertion hole 42. Thereby, the connection between the terminal 21 and the lead wire 6 and the insulation protection of the conductive part are achieved.

If the terminal 21 and the lead wire 6 are to be connected by soldering, as shown in FIG. Insert from the horizontal direction and insert both fitting parts 52 and 53.
By fitting and fixing the fitting portions 22 and 25, the terminal 21
and the connection of the lead wire 6 and the insulation protection of the conductive part. To explain a little further, the terminal block 2 extends from the end surface of the coil bobbin 1, and the terminals 21 are arranged along the surface of the terminal block 2. Of course, the winding end of the coil wound around the coil bobbin 1 is connected to this terminal 21. Furthermore, the fitting portions 22 provided on both sides of the terminal block 20 and the fitting portions 23 provided on the coil bobbin 1 side of the terminal block 2 are connected to the terminal 21.
The engagement surfaces 222 and 223 are parallel to the axial direction of the engagement surfaces 222 and 223. This engagement surface 222.225 has a fitting portion 52.55.
The upper surfaces of the two will come into contact and fit together. Therefore, due to the engagement of the upper surface of the fitting portion 52.53 with the engagement surface 222.223K, the quick connect block 4 and the insulating block 5 will not separate from the terminal 21. As described above, since the quick connect block 4 and the insulating block 5 have the same external dimensions, either of them can be arbitrarily selected and used for the same terminal block 2.

5 and 4 show other embodiments, in which the terminal block 2, the connecting block 4, and the insulating block 5 are fitted in the vertical direction, and the other configuration is shown in FIG. 1. , second
This is the same as the embodiment shown in the figure.

In this embodiment, the lower surfaces of both ends of the terminal block 20 are used as engagement surfaces 200 extending parallel to the axial direction of the terminals 21, and the quick connection blocks 4 are attached to the engagement surfaces 200.
', the upper surface side of the claw part of the fitting part 52' provided on both sides of the insulating block 5' is engaged, and the terminal 21 is connected to the connecting block 4'.
, which prevents the insulating block from coming apart.

FIG. 5 shows an example of the internal structure of the connecting block 4 incorporated in the embodiment, showing the lower end of the built-in S-shaped connecting fitting 41, the horizontal portion of the terminal 21 of the terminal block 2, and the upper end of the connecting fitting 41. and the lead wire 6 from which the insulating coating at the tip has been peeled off are pressed together to establish an electrical connection.

As explained above, according to the discharge lamp ballast of the embodiment, (1) When the type of lead-out wire is a single wire...In the case of a quick connection type stranded wire:
...It can be used in different ways, such as the soldering method.

(2) The quick connect block and the insulating block have the same external shape, and either can be arbitrarily selected and used for the same terminal portion.

(3) Since the quick-setting block and the insulating block have the same external shape, by partially replacing the mold, it is possible to manufacture both using the same large part of the expensive mold. It is possible to reduce mold costs.
