固定部7が形成されている。A structure of a hermetic terminal that solves the above-mentioned disadvantage has been proposed. For example, Japanese Utility Model Application Laid-Open No. 61-182118 discloses a hermetic stem for a crystal unit including at least two metal leads penetrating an insulating glass and a metal ring or a flange surrounding the periphery of the insulating glass. An airtight terminal is disclosed in which a wedge-shaped fixing portion is provided at an end of a metal lead on a side to which a vibrator is fixed, and the end of the wedge-shaped fixing portion is embedded in insulating glass. The mechanical strength is improved. FIG. 4 is a top view of the hermetic terminal of the embodiment and a cross-sectional view of a metal lead portion. A wedge-shaped fixing portion 7 is formed at an end of the lead 6.

揃いになると水晶振動子の固定がし難く、量産ではバラ
ツキの原因となる。The positioning of a metal lead having one end formed in a wedge shape and embedding it in insulating glass is extremely poor in workability. If the wedge-shaped directions of a pair of leads are not uniform, a crystal vibration occurs. It is difficult to fix the child, which causes variation in mass production.

密端子を提供することを目的としている。[0006] If there is a variation in the fixing, the characteristics of the crystal unit will vary, and even if the mechanical strength of the fixing is improved, there will be many disadvantages. SUMMARY OF THE INVENTION It is an object of the present invention to provide an airtight terminal capable of solving the above-mentioned drawbacks and fixing a crystal oscillator firmly and stably.

治具に固定して行われる。FIG. 1A shows an airtight terminal after a step of positioning and fixing a metal header 2, an insulating member, and two leads 1 and 1. The manufacturing method is the same as that of the prior art. (B) is an airtight terminal in which the fixing portion 8 is formed by flattening the end of the lead 1 by pressing or the like. (C) is an airtight terminal after the step of providing a notch 9 in the longitudinal direction of the center lead 1 of the flat fixing portion 8. The notch is formed by a cutter, a laser beam or the like. (D) The hermetic terminal after the step of forming the flat portion divided into two by the notch into a V-shape, a Y-shape or a U-shape. In this case, it is a preferable manufacturing method that two leads are simultaneously formed by pressing alternately and flatly on the basis of the centers of the leads. Each process is performed by fixing the airtight terminal to a jig.

ばよい。FIG. 6 is a front view in which a rectangular crystal resonator is fixed to the hermetic terminal of the present invention. Since the ends of the rectangular crystal unit are fixed by a structure sandwiched between V-shaped fixing parts, they can be securely and firmly fixed. Although the present invention has been described with respect to a hermetic terminal for a crystal oscillator, it goes without saying that the present invention is not limited to a crystal oscillator and can be applied to all hermetic terminals for directly fixing elements to leads. Even in a structure having three or more leads, the fixing portion may be processed only for the element fixing leads.

【発明の効果】気密接合後に固定部を成形するので、気
密封止の際のリード形状は単純(実施形態では丸棒)で
あり、位置決め固定作業が容易となる。According to the present invention, since the fixing portion is formed after the hermetic bonding, the lead shape at the time of hermetic sealing is simple (in the embodiment, a round bar), and the positioning and fixing work is easy.
【0013】気密接合後に固定部を成形するので、完成
後の固定部はバラツキが無く、水晶振動子の組立が安定
し、結果として水晶振動子の特性も安定する。Since the fixed portion is formed after the hermetic joining, there is no variation in the fixed portion after completion, and the assembly of the crystal unit is stabilized, and as a result, the characteristics of the crystal unit are also stabilized.
【0014】固定部の平坦部と水晶振動子の平面部が一
致するため、指示部の面積が大きくなり、水晶振動子と
固定部の固定が安定し、固定部の機械的強度が向上す
る。Since the flat portion of the fixed portion and the flat portion of the crystal unit coincide with each other, the area of the pointing unit is increased, the fixing of the crystal unit and the fixed unit is stabilized, and the mechanical strength of the fixed unit is improved.
