Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an ultrasonic probe plug and an ultrasonic device. Background Art

[0002] The ultrasonic probe plug is used to connect the ultrasonic probe to the ultrasonic host to realize the function of the ultrasonic host. The shell of the existing ultrasonic probe plug is made of die-cast aluminum metal. The metal shell has good anti-interference performance. For ultrasonic probes with low anti-interference requirements, the conventional metal shell solution can meet their needs. However, for ultrasonic probes with high anti-interference requirements, only using a metal shell without adding other shielding treatments can easily affect the signal transmission of the ultrasonic probe, thereby affecting the image quality of the ultrasonic probe. Die-cast aluminum is formed by a die-casting mold. The dimensional error of the die-casting mold is large, which may cause a small gap between the upper and lower shells after assembly. Generally, the assembly surface will be machined. However, whether it is mold forming or machining, there are errors. From a microscopic point of view, there is a small gap between the upper and lower shells after assembly, which cannot meet the use requirements of ultrasonic probes with high anti-interference requirements.
