Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a ballast for a discharge lamp, and more particularly to wiring of a lead wire of a secondary coil to a ballast in which a secondary coil and a secondary fill are mounted on the same core.

[Technical background of the invention]

A discharge lamp lighting circuit using a ballast generally connects a power supply (2) to both ends of the primary coil (1) as shown in Figure 3, and connects one end of the primary coil (1) to one end of the primary coil (1). Wiring is used to connect the other end of the secondary coil (3), which has one end connected in series to the other end of (1), to the discharge lamp (4). For this reason, conventional ballasts for discharge lamps have a primary coil (7) and a secondary coil (8) wound around a pair of molded bobbins f51 and f61, as shown in Figures 1 and 2. ) is attached to form the ballast main body, and a pair of terminals +1) (
The winding start lead wire ff31 and winding end lead wire ■ of the primary coil (7) are connected and fixed to 121, and the terminal (151) provided at one outer end of the bobbin (6) of the secondary coil (8) is connected and fixed. The winding start wire θa of the coil (8) is connected and fixed, and the winding end of this secondary coil (8) is drawn out long and the winding end of the coil is held as a free end with an insulating adhesive tape. In this state, after attaching the iron core to the primary coil (7) and secondary coil (8), wire it as a terminal (crossing wire 08 on one side) provided at one outer end of the -secondary film (force bobbin (5)). In this type of wiring configuration, in a device with a ballast placed in the center of the device body and a lamp socket at both ends, the drawing drawer of the secondary coil (7) Connect the power supply side lead wire to the terminal tint:a to which the wire fi3 (+4) is connected, and connect the terminal circle to which the winding start lead wire 03) of the negative secondary coil (7) is connected, and the winding start of the secondary coil (8). The lamp socket can be connected with a lead wire to the terminal 05) to which the lead wire 0 is connected, and the connection of the lead wire is simplified, which has the advantage of facilitating wiring.

[Behind the scenes technology]

However, in the above-mentioned conventional ballast, the winding end lead wire αn of the secondary coil (8) must be wired across the primary coil (7) during the ballast assembly process, which makes it difficult to automate the ballast assembly. It has become an obstacle.

Therefore, as shown in Figure 4, the end terminal (141) of the bobbin of the primary coil (7) is connected to the terminal (141) at the outer end.
Connect both ends of the connecting wire O to the terminal l provided at the other outer end of the bobbin of the secondary coil (8), and connect the terminal D provided at the outer end opposite the bobbin of the primary coil (7) of the bobbin of the secondary coil (8). Secondary coil (
8) Connect the winding end lead wire On, install this pair of bobbins in parallel to the iron core, and connect the connecting wire part and the winding of the secondary coil (8) at the opposing terminals of this pair of bobbins (191213). A configuration has been proposed in which the end lead wire 0η is connected.In such a configuration, there is no need for a crossover wire from the secondary coil (7) to the secondary coil (8), and automated assembly is easy. However, this configuration requires an insulating material to protect the connecting wire on the upper insulating material of the primary coil (7), similar to the connecting wire of a conventional ballast, and It has the disadvantage that insulation and insertion processes are time-consuming.

[Purpose of the invention]

The present invention was made in view of the above-mentioned drawbacks, and in the assembly process of the ballast, the connecting wire between the secondary coil and the secondary coil is eliminated, wiring can be simplified, and the connecting wire is insulated and protected.

[Summary of the Invention] The present invention comprises a ballast main body by attaching a pair of coils consisting of a primary coil and a secondary coil, each of which is formed by winding a wire around a molded bobbin, to an iron core. Each outer end has a terminal for connecting and fixing the coil lead wire,
A connecting wire connecting the secondary coil and the secondary coil is wound several times around the outer circumference of the primary coil, and both ends are connected to terminals provided at both outer ends of the coil bobbin around which the secondary coil is wound. The lead wire located between the coil bobbins is connected and fixed between the bobbins at opposing terminals, thereby eliminating the need for a crossover wire between the two coils and reducing the amount of protective insulating material.
