Description

Technical Field

[0001] This utility model relates to the technical field of crystal oscillator mounting equipment, specifically a mounting housing for a crystal oscillator. Background Technology

[0002] Crystal oscillators are critical components of electronic devices. Due to their excellent frequency stability and phase noise performance, they are commonly used as time or frequency reference sources in communication, electronics, aerospace, and instrumentation equipment, often referred to as the "heart" of electronic devices. Therefore, in production, crystal oscillators are typically fixed to prefabricated circuit boards using solder joints to form the complete device and achieve its intended function. However, when a crystal oscillator is subjected to significant acceleration from external forces, such as strong vibrations, impacts, or drops, additional mechanical resonance occurs. This interference is added to the signal generated by the crystal oscillator, causing deterioration in phase noise and frequency stability. Furthermore, strong mechanical resonance can cause irreversible damage to the quartz crystal and its support, leading to serious consequences such as crystal oscillator malfunction. Current crystal oscillator structures, due to their small size, present challenges for quick installation and are susceptible to damage from external pressure during use, thus posing certain inconveniences. Therefore, we propose a mounting housing for crystal oscillators. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mounting housing for a crystal oscillator, comprising a main body and a fixing plate. The main body is provided with a circular ring connecting portion, the bottom of the fixing plate is provided with a frustum portion, and a mounting plate is provided above the fixing plate. Fixed grooves are provided at equal intervals on the outer side of the frustum portion, and movable grooves are provided at equal intervals on the circular ring connecting portion. A movable plate is engaged in the movable groove, and the end of the movable plate is engaged in the fixed groove. A slider is provided at the bottom of the movable plate, and the slider is movably engaged in a sliding groove. A positioning spring is provided on the side of the slider. A crystal oscillator body is mounted on the mounting plate, and a baffle is provided on the side of the crystal oscillator body. The outer side of the baffle is connected to a protective plate through a connecting spring.

[0005] In the above scheme, at least three sets of fixing slots are provided.

[0006] In the above scheme, the end of the movable plate is provided with a chamfered portion.

[0007] In the above scheme, the top of the annular connecting part is provided with a threaded hole, and a locking screw is screwed into the threaded hole, the bottom of the locking screw extending into the movable groove.

[0008] In the above scheme, the fixing plate, the frustum portion, and the mounting plate are fixedly connected.

[0009] In the above scheme, a knob is provided on the top of the locking screw.

[0010] In the above scheme, the outer shell body is provided with connection holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The mounting housing for the crystal oscillator has a simple and reasonable structural design and strong practicality. By setting a circular connecting part on the main body of the housing and a frustum on the fixing plate, the frustum is fully inserted into the circular connecting part. At this time, the edge of the frustum gradually squeezes the moving plate, and then the moving plate is locked into the fixing groove under the action of the positioning spring to achieve the positioning effect, thus achieving the effect of quick installation. Afterwards, the fixing effect of the moving plate can be further improved by rotating the locking screw, which effectively ensures the installation stability of the crystal oscillator mechanism and enhances the deformation resistance of the equipment. Furthermore, by setting a buffer mechanism consisting of a baffle, connecting spring and protective plate on the outside of the crystal oscillator body, the impact of external impacts such as strong vibration and strong impact on the internal mechanism can be reduced.
