[0002] In the prior art, the wire outlet mode of insertable ultrasonic flowmeters mostly adopts a direct wire outlet mode, that is, the wire outlet of the transducer is directly connected to the main unit. However, during the use of ultrasonic flowmeters, long-term operation may cause problems such as transducer breakage and malfunction. At this time, replacement is required. In most cases, the distance between the main unit and the transducer is relatively far. When replacing the transducer, generally the transmission cable connected to the main unit is replaced together. The length of the transmission cable is relatively long. If replaced together, it will increase the replacement time and cost. Summary of the Invention

Inside the front end of the transducer body, there is a piezoelectric ceramic sheet. One end of the positive wire and the negative wire are both welded and fixed to the piezoelectric ceramic sheet. The other ends of the positive wire and the negative wire pass through the transducer body and enter the inside of the junction box and are connected to the ceramic terminal inside the junction box. The ceramic terminal is connected to one end of the transducer cable. The other end of the transducer cable extends out from the wire outlet nozzle of the transducer body.
[0005] Further, a groove is provided on the outer side wall of the end of the transducer body adjacent to the junction box. The groove facilitates tightening when installing the junction box.
[0006] Further, a ring-shaped step is provided on the inner wall of the side opening of the junction box. The sealing ring is arranged on the ring-shaped step, and the rear end of the transducer body presses tightly against the sealing ring.
[0007] A method of using an insertable ultrasonic transducer structure with a junction box structure, connecting the positive wire and the negative wire in the transducer body to the ceramic terminal in the junction box, then detachably connecting the transducer body to the junction box by threads. One end of the ceramic terminal in the junction box is connected to one end of the transducer cable, and the other end of the transducer cable extends out of the junction box and is connected to the host.
