[0020] The utility model will be further described in detail in combination with the drawings and specific embodiment: refer to Figures 1-5 A quick installation shell of quartz oscillator includes first shell 1 and second shell 2. The periphery of the first shell 1 is provided with a plurality of quick connectors 3, and the second shell 2 is provided with connecting holes 4 matched with the quick connectors 3. By inserting the quick connector 3 into the connecting hole 4, the connection of the first shell 1 and the second shell 2 can be completed.

[0021] Further, the quick connector 3 is composed of a connecting column 9 and a connecting round table 10 at the end of the connecting column 9. The connecting round table 10 includes a first plane 11 and a second plane 12. The first plane 11 is connected to the end of the connecting column 9, and the diameter of the first plane 11 is greater than that of the second plane 12 at the end, forming a conical structure in cross section.

[0022] The outer edge of the second shell 2 is divided into a first section 5 and a second section 6, which are the top and bottom of the second shell 2 respectively. Therefore, a connecting hole 4 is provided through the first section 5 and the second section 6. Specifically, the connecting hole 4 includes a first hole body 7 extending from the first section 5 and a second hole body 8 extending from the second section 6.

[0023] As shown in the figure, the diameter of the first hole body 7 is smaller than that of the second hole body 8. The first hole body 7 matches the connecting column 9, and the diameter of the second hole body 8 is slightly larger than the diameter of the second plane 12 of the connecting circular platform 10. During assembly, after the connecting circular platform 10 of the quick connector 3 passes through the first hole body 7, the connecting circular platform 10 is embedded in the second hole body 8, so that the quick connector 3 is connected in the connecting hole 4, that is, the connecting platform is limited outside the second hole body 8, thereby realizing the locking of the first shell 1 and the second shell 2.

[0024] The materials of the first shell 1 and the second shell 2 are plastic, so the quick connector 3 can temporarily deform the first hole body 7 and pass through to realize the quick connection of the first shell and the second shell.

[0025] Further, in order to facilitate the installation inside the shell, a placement groove 13 is arranged in the center of the second shell 2. The shape of the placement groove 13 matches the outer contour of the base 14, which is used to fix the base 14. The base 14 is integrally arranged, that is, the quartz crystal wafer 15 is pre-installed on the base 14, and the two sides are connected with the communicating pins 16. The pins 16 extend from the base 14 and pass through the through holes in the side wall of the second shell 2 to realize external circuit connection.

[0026] In order to improve the sealing performance, a sealing ring is arranged between the first shell 1 and the second shell 2. Specifically, the sealing ring 19 is sleeved on the connecting column 9 of the quick connector 3, so that it is supported on the outer surface of the first shell 1. The material of the sealing ring 19 is elastic rubber and the cross section is oval.

[0027] A first chamfer 17 is arranged at the entrance of the first hole body 7. When the first shell 1 and the second shell 2 are connected, the sealing ring is pressed and embedded in the first chamfer 17. At the same time, the sealing ring 19 seals the first shell 1 and the second shell 2, and the sealing ring 19 is embedded in the first chamfer 17, thereby realizing the stable connection between the first shell 1 and the second shell 2, that is, the connecting column 9 cannot shake in the first hole body 7, thereby improving the qualified rate of the product.

[0028] Further, the inner wall of the connecting hole 4 of the second shell 2 is also provided with an annular groove, which cooperates with the outer side of the first chamfer 17. After being pressed, the sealing ring 19 deforms and fills the gap between the first shell 1 and the second shell 2, thereby enhancing the axial sealing effect and stabilizing the connection of the first shell 1.

[0029] Meanwhile, the first shell 1 is provided with a plurality of protrusions 18, which are arranged outside the placing groove 13 and cooperate with the connecting column 9 to enable the sealing ring 19 to be sleeved outside without affecting the placement of the base 14 in the placing groove 13.

[0030] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
