Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of the base of a crimp-type metal container that supports a crystal oscillator.

Conventionally, this type of crimp-type base is shown in Figures 1 and 2.
As shown in the figure, a flat metal support 8 having protrusions 6, 6 and through holes 7, 7 is placed inside a metal base 1 formed into a cross-sectional shape, and the protrusions 6, 6 are placed on the metal base 1. It was fitted into the openings 3, 3 provided in the bottom plate 2 of 1, and the protrusions 6, 6 and the openings 3, 3 were bonded together with silver solder 9. The base is sealed in the through holes 7, 7 of the metal support 8 with insulating materials 10, 10, and the lead wires 11, 11 are inserted thereinto.
A crystal oscillator 12 is connected to the tips of 1 and 11, and the metal base 1 is covered with a cross-sectional metal case 13.
The bent side 5 continuous to the edge of the side wall 4 and the bent side 14 formed at the opening side edge of the metal case 13 are pressed and sealed using a press machine.

However, as shown by the chain line in FIG. 1, the impact during this crimping deforms the metal support base 8 that supports the crystal oscillator 12, adversely affecting the crystal oscillator.
There was a drawback that the oscillation frequency was distorted.

The object of the present invention is to provide a crimp-type base for a crystal oscillator that solves the above-mentioned drawbacks.

The crimp-type base for a crystal oscillator of the present invention is made by crimping and fixing a metal support base that supports a crystal oscillator, which is reinforced by curved upwards on both sides, to the metal base, thereby covering the metal case and forming the metal base. To protect a crystal oscillator without deforming a metal support base supporting the crystal oscillator due to the impact of the crimping when the bent part of a metal case is crimped and sealed. It is characterized by

Embodiments of the present invention will be described below based on the drawings.

Note that explanations of parts that overlap with those of the conventional product will be omitted.

3 and 4 show the metal support of the present invention, 16, 16 are protrusions protruding from the lower surface of the metal support 18, and 17, 17 are the protrusions 16, 16.
The lead wires 11, 11 opened in the insulating materials 10, 10
This is a through hole for sealing and loose passage. The metal support base 18 is formed with both sides 20a, 20a curved upward about a center line 19 passing through the protrusions 16, 16 and the through holes 17, 17.

The metal support 18 thus formed is placed on the bottom plate 2 of the metal base 1, as shown in FIG. 5 and FIG.
The protrusions 16, 16 are fitted into the base, and the openings 3, 3 and the protrusions 16, 16 are bonded with silver solder 9 to form a base.

As shown in FIG.
1 and 11 loosely, and insulating material 1 such as glass.
The crystal oscillator 12 is connected to the lead wires 11, 11 by sealing with 0 and 10. Then, the metal cover 13 is covered, and the bent portion 14 of the metal cover 13 is overlapped and pressed onto the bent portion 5 of the metal base 1.

As mentioned above, in the present invention, both sides of the metal support that supports the crystal oscillator are curved upward and fixed to the metal base, so that when the bent parts of the metal base and the metal cover are overlapped and crimped together, , the metal support will not be deformed by impact. In particular, the bending strength in the direction between the through holes through which the lead wires are loosely passed is strong, so even if shock or vibration is applied, the crystal oscillator will not be adversely affected or damaged, which is extremely useful for quality control.
