図示しない一次、二次コイルが巻線されている。 The present invention will be described below with reference to embodiments shown in the drawings. 1 to 3, 1 is a resin cup-shaped case, 1a is a cylindrical flange integrally molded on the bottom of the case 1, and the tip that protrudes axially inside the case 1 has an axially Four cut grooves 1b are formed extending into the groove, and a tapered portion 1c is formed on the inner circumferential surface of the tip end thereof. Further, on the outer periphery of the portion of the flange portion 1a that protrudes to the outside of the case 1, a cord insertion tube 1d is similarly formed integrally with the case 1 and protrudes in the axial direction. Reference numeral 2 denotes a nail-shaped secondary terminal, whose base part is fixed to a holding base 12 such as a secondary bobbin, and whose tip end is exposed in the cord insertion tube 1d through the center hole (fitting hole) of the flange part 1a. There is. Reference numeral 3 indicates a resin cast into the case 1, and reference numeral 13 indicates a high voltage cord inserted and held within the cord insertion tube 1d, and its core wire is connected to the secondary terminal 2. Reference numeral 14 denotes a core whose both ends protrude outside the case 1, and primary and secondary coils (not shown) are wound around the outer periphery of this core 14.
上記構成において、二次ターミナル２をケース

組付作業性がよくなる。 In the above configuration, when the secondary terminal 2 is inserted into the fitting hole of the case 1, the flange portion 1a serves as a guide, so the secondary terminal 2 can be easily inserted, and the flange portion 1a and the Due to the increased fitting area with the secondary terminal 2, there is no need to harden the fitting degree of the secondary terminal 2,
Improves assembly workability.

is provided, so that the casting resin 3 can fit into the groove 1.
Since it sufficiently extends around the fitting portion of the secondary terminal 2 via the flange portion 1a, the space between the flange portion 1a and the terminal 2 can be made airtight.

果がある。 As described above, in the present invention, a cylindrical flange is provided at the bottom of the case that projects inward and axially to clarify the position of the fitting hole and to ensure that the secondary terminal does not fit into the case. Since the combined area is increased, the workability of assembling the secondary terminal is improved.Moreover, a cut groove extending in the axial direction is provided at the tip of the flange part, so that the casting resin can be distributed around the fitting part of the secondary terminal. This has the effect of making the secondary terminal fitting part airtight.
