Embodiment 1

[0021] Example 1: refer to figure 1 , is the basic embodiment of a tuning fork type quartz crystal resonator base of the present invention, and it comprises seat ring 2, glass bead 3 and lead wire; Described lead wire 1 passes through glass bead 3, and this glass bead 3 outer layer is covered with seat ring 2; the upper port of the seat ring 2 extends inwardly to form a spigot 21, and the lower port of the seat ring 2 is an opening extending downward along the inner wall; the part of the lead wire 1 outside the upper end surface and the lower end surface of the glass bead 3 exceeds The upper end surface and the lower end surface of the glass beads 3 have a certain length.

Embodiment 2

[0022] Example 2: The difference from the above-mentioned embodiment 1 is that the outer diameter a of the seat ring is 1.7 mm to 2.7 mm, the inner diameter b of the seat ring is 1.3 mm to 2.3 mm, and the height c of the seat ring is 0.9 mm to 1.4 mm. Good fit with the shell of the existing standard parts, so as to ensure good airtightness after the shell is socketed, and at the same time, the shell will not burst. There are two lead wires 1, the two lead wires 1 are parallel, the distance d between the centers of the lead wires is 0.6 mm to 0.9 mm; the length e of the lead wires is 7 mm to 12 mm, and the diameter f of the lead wires is 0.2 mm to 0.4 mm. If it exceeds this range, For example, when the distance d between the two lead wires is reduced, the glass bead 3 between them is likely to be broken after being formed, and if the distance d is too large, the insulation distance between it and the seat ring 2 will be insufficient. The glass bead 3 is a sphere with two thro...

Embodiment 3

[0023] Example 3: The difference from the above-mentioned embodiment 2 is: the base of the tuning fork type quartz crystal resonator has an outer diameter a of the seat ring of 2 mm to 2.5 mm, an inner diameter of the seat ring of 1.5 mm to 2 mm, and a height c of the seat ring of 1.1 mm to 1.3mm.

Abstract

The invention relates to a tuning-fork-shaped quartz crystal resonator base, comprising a base ring, a glass bead and a lead wire, wherein the lead wire penetrates through the glass bead and the base ring is sleeved on the outer layer of the glass beam; the upper end of the base extends inwards to form a seam allowance; the lower end of the base ring is an opening with an inner wall which extends downwards; and the part of the lead wire, which is out of an upper end face and a lower end face of the glass bead, is beyond the upper end face and the lower end face of the glass bead for a certain length. The tuning-fork-shaped quartz crystal resonator base is easy to produce, reasonable in structure and lower in cost.

Description

technical field [0001] The invention relates to an electronic component, in particular to a tuning fork type quartz crystal resonator base. Background technique [0002] The quartz crystal includes a shell with one end open, a quartz wafer and a base for sealing the opening of the shell, and the base is further composed of a seat ring, glass beads and leads. Usually, the above-mentioned quartz wafers are mostly tuning fork type, and there are two lead wires, which are welded and fixed to the mounting electrodes on the surface of the tuning fork type quartz wafer. The wafer is sealed in the housing. There are deficiencies in the structure of the base of the quartz crystal resonator in the prior art, and the product manufacturing is relatively difficult and the cost is high. Contents of the invention [0003] The object of the present invention is to provide a tuning fork type quartz crystal resonator base which is easy to produce, reasonable in structure and low in cost. ...
