Description of the Related Art Conventionally, a spark gap device as shown in FIG. 2 has been used to absorb surges flowing into electronic equipment from power sources or antenna lines. That is, this spark gap device uses conductors 2 and 3 whose tips are shaped like hooks so that the shortest distance C is predetermined in the discharge gap part 1.
It has a structure in which it is fixed to a holding layer 4 made of an insulator. Moreover, in order to prevent deformation of the conductors 2 and 3,
A box-shaped case 5 is attached to cover the outer periphery. Note that 8 is a printed wiring board.

実施例
以下、本考案の一実施例のスパークギヤプ装置
を図面を参照して説明する。Embodiment Hereinafter, a spark gap device according to an embodiment of the present invention will be described with reference to the drawings.

８に取付けられて使用される。 As shown in FIG. 1, conductors 2 and 3, which are uniform in the longitudinal direction, are placed on the bottom surface of a case 7, which is made of an insulating material and has a space 6 opened on one side, with a constant distance C maintained at one end thereof. Fix it. The other ends of the conductors 2 and 3, which are not fixed, are bent within the space 6 so as to move away from each other and protrude from the opening, and are used by being attached to the printed circuit board 8 at this protrusion.

間良好な状態のスパークギヤプが期待できる。 The shortest distance between the conductors 2 and 3 is near where they are fixed to the case 7. Therefore, this portion becomes the spark gap portion 9. This spark gap part 9
Since the conductors 2 and 3 near are fixed to the case 7, they are not easily deformed. Further, the conductors 2 and 3 do not need to have a special shape to form a gap. Note that 10 is a protrusion formed on the bottom surface of the case 7 between the conductors 2 and 3 to prevent easy sparking. Further, when installed, the spark gap portion 9 is surrounded by the case 7 and the printed circuit board 8, and is less affected by dust, so that the spark gap can be expected to remain in good condition for a long period of time.

良好な性能が期待できるものである。Effects of the invention As described above, the spark gap device of the invention has the following advantages:
Since the area fixed to the case becomes a spark gap, it is difficult to deform and a stable spark gap is obtained.When using this spark gap, the case is surrounded by printed circuit boards, etc., so a separate protective case is required. without doing,
There is very little performance deterioration due to dust, etc., and good performance can be expected for a long time.
