ツダである。 In electronic/electrical components and electronic/electrical devices, terminals are drawn out from the case in an insulated state. To explain this using the stem structure shown in FIGS. 1 and 2, 1 is a linear terminal, 2 is a terminal into which the terminal 1 is inserted and fixed,
The insulating part 3 made of, for example, glass is, for example, a ring-shaped metal header to which the insulating part 2 is surrounded and fixed.

決できないし、誘電損失が増大する。 With such a structure, especially when used in a high frequency range, capacitance and dielectric loss due to the presence of the insulating section 2 between the terminal 1 and the header 3 become a problem. Therefore, if the diameter of the terminal 1 is made smaller, there will be concerns about the strength of the terminal. Furthermore, if the diameter of the insulating portion 2 is increased, the eternal problem of miniaturization of electronic components cannot be solved, and dielectric loss increases.
それゆえにこの考案の基本的目的は、上記の静
電容量や誘電損失を減少させることである。 Therefore, the basic objective of this invention is to reduce the above-mentioned capacitance and dielectric loss.
すなわちこの考案では、絶縁部に孔を設けるこ

にのべる第2の実施例にもあてはまる。 FIG. 3 shows a first embodiment, in which a plurality of holes 13 are provided in the insulating part 12. The hole 13 may be a bottomed hole or a through hole depending on the purpose and use. Also, depending on the purpose and use, when the terminal 1 and the header 3 are arranged coaxially, it may be better to arrange the hole 13 so as not to destroy the symmetry, but when not used as a coaxial line, Alternatively, the hole 13 may be provided in an anabalance. These matters also apply to the second embodiment described below.

The influence of the insulators 12 and 20 between the terminal 1 and the header 3 is reduced, and unnecessary capacitance and dielectric loss are reduced.
第6図は第3図の例でさらに静電容量を小さく

and the holes 32 arranged on the outer concentric lines are not lined up in the radial direction from the center of the insulating section 30 to equivalently lengthen the path along which the lines of electric force run, thereby reducing the capacitance. . Further, in the example shown in FIG. 7, an intermediate rim 43 is provided between the inner rim 41 and the outer rim 42, four spokes 44 are provided between the rim 41 and the rim 43, and the rim 43 and the rim 4
Four spokes 45 are provided between the two spokes 44 in a positional relationship that is not aligned with the spokes 44 in the radial direction, and four bottomed holes 46 exist between the spokes 44 and four holes 45 are provided between the spokes 45. Bottom hole 4
7. With this structure, the holes 46 and 47 are not lined up in the radial direction from the center of the insulator 40, which equivalently lengthens the path along which the lines of electric force run in the spoke, thereby reducing the capacitance.

いものである。 As is clear from the above embodiments, this invention provides a terminal drawer structure that includes a terminal, an insulating part into which the terminal is inserted and fixed, and a metal part in which the insulating part is surrounded and fixed. Since the total amount of insulating material is reduced by providing holes in the terminal, it is possible to reduce unnecessary capacitance and dielectric loss caused by the presence of insulating material, and it is also possible to make the terminal sufficiently thick to increase strength, making it possible to reduce the amount of insulating material. There are great benefits when applied to the hermetic seal structure of electronic components and devices.
