[0016] The base has an upper folded edge on one opposite side, which contacts the surface of the housing.

[0017] As a further description of the above technical solution:

[0018] The upper end of the folded edge is provided with an arc-shaped bend.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, when the circular quartz crystal is packaged on the base, the two sides of the quartz crystal are supported by brackets, and the edge of the quartz crystal passes through the strip hole of the bracket, so that the bracket firmly adheres to and positions the quartz crystal, effectively improving the quality of the plug-in crystal oscillator.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-4 This utility model provides a technical solution: a plug-in crystal oscillator structure, comprising:

[0032] The base 1 has pins 11 on it, and a bracket 12 is provided on the top of the pins 11;

[0033] A quartz crystal sheet 2 is provided with a silver-plated electrode 21. A symmetrically arranged support 12 is provided on both sides of the quartz crystal sheet 2. A strip hole 121 is provided on the support 12. The edge of the quartz crystal sheet 2 passes through the strip hole 121. The quartz crystal sheet 2 is bonded and fixed to the support 12.

[0034] The shell 3 is bonded and fixed to the base 1.

[0035] The inner wall of the housing 3 is provided with annular inner protrusion 31, which contacts the side wall of the base 1. The inner protrusion 31 strengthens the anti-deformation ability of the bottom opening of the housing 3, improves the connection quality between the housing 3 and the base 1, and improves the sealing performance.

[0036] Working principle: When the circular quartz crystal chip 2 is packaged on the base 1, the two sides of the quartz crystal chip 2 are supported by the bracket 12, and the edge of the quartz crystal chip 2 passes through the strip hole 121 of the bracket 12, so that the bracket 12 firmly adheres to and positions the quartz crystal chip 2, effectively improving the quality of the plug-in crystal oscillator.

[0037] Example 2

[0038] This embodiment further improves upon the above embodiment by providing the following technical solution: a glue groove 13 is provided on the side wall of the base 1. The glue groove 13 is used to fill glue so that the housing 3 can be bonded and fixed to the base 1.

[0039] Specifically, two parallel annular ribs 14 are provided on the side wall of the base 1, and the two annular ribs 14 and the side wall of the base 1 form an adhesive groove 13. The annular ribs 14 effectively restrict the adhesive and support the shell 3 at the same time.

[0040] Example 3

[0041] Based on the above embodiments, this embodiment further improves the technical solution as follows: an upper folded edge 15 is provided on one opposite side of the base 1. The upper folded edge 15 contacts the surface of the housing 3, fully positioning the housing 3, further improving the connection quality between the housing 3 and the base 1, and improving the sealing performance.

[0042] Furthermore, the upper end of the upper folded edge 15 is provided with an arc-shaped bending edge 151, which can effectively prevent obstruction when the shell 3 and the base 1 are plugged and assembled by pre-opening the upper folded edge 15, and at the same time avoid scratching the shell 3.
