Description

The present invention relates to a support fitting for holding a crystal unit used in a crystal unit used in an electronic device or the like, in particular, a unit in which a microcomputer or a transmitter is mounted.

Conventionally, a crystal in a crystal unit is connected to a support metal fitting by bonding, and is connected to an electrode for taking out an electric signal to the outside by spot welding or the like. This support bracket has an elastic support function to alleviate the impact in order to prevent the crystal itself from being damaged when the crystal unit receives impact such as impact or vibration from the outside, and the equipment cannot be used. Was adopted.

For that purpose, there were the following problems.
The shape of the support bracket was made elastic with respect to pitching in the vertical direction and rolling around the longitudinal axis of the crystal due to manufacturing constraints and lack of experience in this field, but the vertical axis in the electrode direction No consideration was given to turning and yawing. For this reason, it may be damaged during use, and it may become impossible to use the mounted equipment.

In the current support bracket, the crystal is supported by two support members. However, the support member is one, and the shape and processing method of this one are reviewed and the left and right shapes are asymmetrical. .

The number of support members from the electrode connection part to the crystal fixing part is changed from two to one, and the rising part of the specified angle is provided at this part, so the rigidity of yawing and pitching is almost equal without changing the plate thickness. Can be adjusted to the value.

Since the left and right shapes are not intended, it is easy to balance the left and right forces and movements during yawing, pitching and rolling.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
(A) Side column support provided with a raised portion (6) in which a part of the material is raised at a specified angle on one side of a stepped crystal fixing portion (1) made of a thin metal material (4) is provided, and an inter-post support part (7) along the longitudinal direction of the crystal fixing part (1) is provided, and a substantially rectangular central support part (2) provided along the side support part (4). Connect to one end of
(A) The support fitting (3) of (a) and the support fitting 2 (10) having an asymmetric shape are opposed to each other, and the electrode (8) and the electrode 2 (12) on the pedestal (11) side of the crystal resonator The electrode connection part (5) and the electrode connection part 2 (13) are aligned and provided.
When the present invention is used in the above configuration,
The electrode connection part (2) of the center column part (2) of this product having two asymmetrical shapes at the tip part of the electrode (8) and the electrode 2 (12) arranged on the left and right of the base part (11) of the crystal resonator 5) and the electrode connecting part 2 (13) are firmly connected electrically and mechanically using spot welding or ultrasonic waves, and the crystalline lens (9) is fixed to the left and right crystal fixing parts (1) by bonding. Thereafter, a metal cap is covered and sealed by brazing.
At this time, the side column portion (4) may have a shape in which the rising portion (6) is not provided.

It is a perspective view of the support metal fitting of this invention. It is a disassembled perspective view of the crystalline lens of this invention, a support metal fitting, and a base. It is a disassembled perspective view using the conventional support metal fitting. It is a disassembled perspective view of the other plan of this invention.
